In this tutorial, we're going to build a simple Phoenix application based upon NimblePublisher. I will then show you how you can integrate Haystack to add full-text search for your content. This tutorial is going to be focused on indexing content from NimblePublisher, but in reality, the data you want to index can come from anywhere and it can be in any shape or form.
Mar 22, 2023
Full-text search is a common requirement in a number of different types of website and web applications. I recently needed the ability to index and search content on a project I've been working on. However, using an off-the-shelf search solution didn't make sense for this project. Instead of building a closed-source solution as part of that project, I decided to build an open source library that I could use as a building block for my other Elixir projects that fit the same requirements. That open source library is Haystack, a simple, extendable full-text search engine written in Elixir.

I recently ran into a problem embedding XML templates in a Phoenix 1.7 application. It took me a while to figure out what was going wrong and so I thought I'd write up this blog post to try and save other people time in the future. This tutorial shows how to use embedded templates in Phoenix 1.7 when the format of the template is not HTML.

How often do you think if you had known how difficult something was going to be, you would have never started in the first place? Underestimating how difficult a task is going to be can be a valuable form of ignorance because without it, you might not start the project in the first place. In this article we are going to be looking at how ignorance can be beneficial when it comes to choosing what you should be working on.

A weekly review is a dedicated time to reflect on what you did this week, and what you will do in the coming week. It's an opportunity to re-align your goals, make improvements to your workflow, and to gain perspective on where you are on your journey. There are many benefits to getting into the habit of performing a weekly review. In this article we're going to be looking into weekly reviews, the benefits of doing a weekly review, and how you can set up your own weekly review for success.

The "Eat the Frog" productivity method is where you pick the most important thing from your to-do list and work on it first. It's a very simple way to prioritise your work and ensure you are always investing your energy into your most important work. The phrase was coined in Brian Tracy's productivity book, "Eat That Frog!: 21 Great Ways to Stop Procrastinating and Get More Done in Less Time", and is taken from the Mark Twain quote "if you have to eat a live frog, do it first thing in the morning and nothing worse will happen to you for the rest of the day".

The time it takes you to complete tasks is often longer than you expected. This happens to me quite regularly, and so I'm sure it probably happens to you too. Underestimating the time required to complete a task is known as the planning fallacy. The planning fallacy can have very serious consequences such as projects overrunning, deadlines missed, and budgets obliterated. This is why understanding the planning fallacy is so important. Once you are aware of the problem you can take steps to make better predictions on how long a task will take.

An important thing to consider when choosing what to work on next is how to minimise context switches. Whilst preemption can be important under certain circumstances, generally you want to avoid wasting time and energy on the meta work of switching tasks. Batching your work is a good way to ensure you maintain focus on the given task by dealing with similar tasks all in one go, instead of sporadically throughout your other tasks.
Aug 23, 2022
Task preemption is when you temporarily stop working on your current task to switch to a different task, with the intention of completing the previous task at a later date. In certain situations, switching from what you are currently working on to work on something else can be more efficient, but it comes at the price of switching costs. This is a counterintuitive, but important thing to consider if you want to optimise how you work to get the most done.

The pomodoro technique is a productivity method that breaks tasks into short, focused periods of work. During each work period, you focus on the task at hand, and then after the period has finished you would take a short break. As you are forced to break tasks down into small chunks, the pomodoro technique is good for people that face an overwhelming to-do list and don't know where to start. The technique also promotes regular breaks as a way of resetting your mind between tasks.
Aug 16, 2022
A sure fire way to break your flow state is to get interrupted. When working on a task that has a long ramp up time, a constant barrage of interruptions can be the kiss of death to achieving what you set out to do. Interrupt Coalescing is where you block out interruptions so that you can concentrate on completing tasks without distraction. It is the intentional process of ignoring distractions, or making yourself unavailable to interruption in order to concentrate on the task at hand.

Kanban is a task management method that originated from the lean manufacturing movement. It was first developed by Taiichi Ohno, an industrial engineer at Toyota in Japan. Kanban is a way to visualise the current workload using cards that move between stages of the production line. Whilst Kanban originated in lean manufacturing, it has made the leap to the mainstream as a simple and flexible way to manage projects.

One of the most difficult things in deciding what to work on next is getting the balance right between priority and dependencies. Usually tasks don't exist in isolation, every task on your task list will have different priorities and certain tasks will need to be completed before other tasks can be started. Understanding how to choose the right thing to work on next with these two things in mind is incredibly difficult.

The afternoon slump is a period in the early afternoon where a lot of people experience a drop in energy, motivation, and focus. Occurring usually just after your lunch break, the afternoon slump can be a killer for your productivity. However, it's possible to avoid the afternoon slump and maintain a high level of productive output during the working day. Once you understand your mind and body's natural ultradian rhythm, you can better manage the precious resource of your energy.

There are many different ways to sort and prioritise your to-do list. For example, you might want to prioritise your tasks by the earliest due date so that you work on tasks that are due first. Or perhaps you want to prioritise by the eisenhower matrix to ensure you are working on your most important tasks first. However, if you're feeling overwhelmed by a burgeoning to-do list, sometimes you just want to get as much stuff done as quickly as possible. This is known as the "shortest processing time" method because you are prioritising tasks by how quickly they can be completed.
Jul 27, 2022
Getting Things Done (also known as GTD) is one of the most popular productivity methods for organising and processing the tasks you need to complete. It's a particularly effective method if you're feeling overwhelmed with everything you need to remember and do. One of the core philosophies of the Getting Things Done method is to get the things you need to do out of your head and into a system to be organised and processed. The human brain is better for processing information, rather than storing it. Getting everything you need to remember out of your head also significantly reduces anxiety because you no longer have to be worried about remembering everything.

A common situation I'm sure we've all faced is when we have a deadline, but we procrastinate and delay working on the task until the very last minute. Panic ensues and it's a crazy mad dash to the finish line in order to deliver the work on time. This phenomenon is known as student syndrome and it's a common problem that affects nearly everyone, not just students! In this article we're going to be looking into the problem of student syndrome, and the one clever trick you need to beat it once and for all.
Jul 21, 2022
There are many things to consider when evaluating what task you should work on next. It's not always as simple as sorting your tasks by due date and then picking the first off the top of the list. The importance of each of your tasks should be evaluated carefully, as this is likely going to have an outsize impact on how productive you are.
Jul 19, 2022
It's easy to convince yourself that in order to get more done you need to work longer hours. But forcing yourself to do work past your body's capacity can actually cause you to be less productive. Working more intensely for shorter periods of time with extended periods of rest and recovery is actually a better strategy.
Jul 14, 2022
It doesn't matter who you are, every person on planet Earth only has 24 hours in a day. It's impossible to make more time, and so in order to maximise your productivity potential, you need to make the most of your time. Using time as a fixed constraint turns out to be a really great thing. When time is a fixed resource, it means you need to be smarter with how you spend it.
Jul 12, 2022
Our minds and bodies have evolved over millions of years. We are who we are because of the lived experiences of our ancestors. Everything that we know is a delicate balance. If we work with this harmony, instead of against it, we can achieve great things.

Moore-Hodgson's algorithm is an approach to scheduling work that aims to minimise the number of tasks that are late, rather than the lateness of any particular task. The algorithm was presented in 1968 by J. M. Moore, with an alternative algorithim attributed to T. E. Hodgson.
Jul 05, 2022
A common misconception is, working on the same types of tasks will have the same type of outcomes. Your current energy level has a disproportionate impact on the outcome of any task you take on, yet we so often neglect to be mindful of choosing what to work on next. This can mean attempting to complete a task that does not match your current energy level could require more effort and will take longer to complete than if you chose to tackle it at a different time.

Choosing the right productivity method is all about selecting a strategy that optimises for your specific goals and objectives. If you choose a method that optimises for something you don't care about you are guaranteed to not get the result you were looking for. The "earliest due date" method optimises for reducing the lateness of the most late task at the expense of very other task that could also end up being slightly late.
Jun 28, 2022
You only have a certain amount of hours in the day to get stuff done. Everyone feels the pressure to be productive. However, forcing yourself to work on tasks that don't match your energy is a recipe for disaster. This can lead to a downward spiral that eventually results in burnout.
Jun 16, 2022
The "last in, first out" productivity method is a simple system for choosing the next thing to work on by what was added to the queue last. It's a straightforward, and predictable method for organising your tasks that originates from the world of lean manufacturing. In this post we're going to be looking at the "last in, first out" method, its benefits, drawbacks, and when you might want to use it to organise your tasks.

We are inundated with information from the moment we wake up, to the moment we go to sleep. We are constantly making decisions, but over the course of a day, your ability to make decisions significantly decreases. Your capacity to make decisions is a finite resource that is drained as your energy is depleted. This phenomenon is known as decision fatigue.
Jun 09, 2022
Having a methodology for completing tasks doesn't need to be complicated. The most important thing is that the method achieves your desired goal. Using a productivity methodology can simplify the process of getting stuff done because it can reduce the decision fatigue inherent in picking what to do work on next.
Jun 07, 2022
Choosing the right thing to work on is a very difficult problem. Evaluating the nuance of every task you've got on your to-do list is cognitively exhausting. The problem is compounded when we are instinctively drawn to tasks with certain characteristic profiles, even if completing those tasks will not be beneficial to our longer term goals. This distinction can be seen in the choice between urgent and important tasks.

When you're looking for a solution to your productivity problems, it can be tempting to jump on the latest trendy method. If you hear of a method that works for other people, why wouldn't it also work for you? However, many people bounce from method to method, never really finding something that works. All productivity methods advertise themselves as the one true way to solve your productivity predicament. However, no single productivity method is a one size fits all solution. Every productivity method optimises for a specific goal, and so the reason why your productivity method failed is not because the method is bad, it's because it's achieving the wrong goal.

"One of the most popular ways people manage the things they need to do is via a calendar. A common expression you might have heard is, "if it's not on the calendar, it doesn't get done". In certain situations, a calendar can be the perfect way to manage your tasks. If everything you need to do revolves around events pre-scheduled for fixed points in time, a calendar is the perfect tool for the job. But for most people, using a calendar as a to-do list is a terrible solution. If you are currently managing your tasks via a calendar, but you're feeling overwhelmed and not making progress, you might be using the wrong tool for the job.
May 26, 2022
Productivity is one of those problems that has always remained unsolved. The reason why it's always been an elusive problem is because the very concept of productivity is such a big, fuzzy concept. The atomic unit of productivity is a task, but tasks are a vague concept that are defined by any number of external factors. Tasks are also often not static, but in fact evolve over time or due to the stimulus from a whole host of different inputs.

Choosing the right thing to work on next is more complicated than simply picking the first thing off the top of your task list. This is particularly important for freelancers, where you have a wide variety of tasks from working on creative problem solving tasks, routine admin tasks, or client calls and presentations. Selecting the right task to work on in any given situation depends on a number of complicated factors, including the specific context you find yourself in. But it's incredibly difficult when your tasks are so completely different from each other.
May 19, 2022
It's common wisdom that you shouldn't try and hold all of the things you need to do in your head at once. Productivity experts have been preaching this mantra since the dawn of productivity experts. Getting your tasks down onto paper, or in an app is a really good way of creating some space to think. When you don't have to rely on remembering everything, you can concentrate your brain cycles on thinking through those tricky problems.
May 17, 2022
Choosing the right thing to work on next is a very important aspect of working productively. However, most people leave it up to chance by either deciding what to do work on next by whatever is at the top of their task list at the time, or by having a quick scan of their tasks and settling on the first thing that jumps out at them.

After a 6 year hiatus from writing blog posts, the author has developed Prise, a smart productivity application that uses machine learning to build a profile of tasks on a todo list. The idea for Prise was originally conceived in 2010 and the author is now excited to finally put their ideas out into the world. The author will be writing about business and technology, but mainly focused on building Prise. Those interested can sign up for the Prise early access list.

An explicit contract defines the public API of a module, allowing consumers to use the module in a generic way and switch between implementations easily. Behaviours in Elixir are modules that define the contract, and any module that uses the behaviour must implement the contract callbacks. Implementing a behaviour requires using the @behaviour annotation and implementing the callbacks as specified. This allows for interchangeable modules that can be composed together and easily switched out when needed.

Elixir is a dynamic programming language that allows developers to infer types at runtime, rather than requiring them to declare them upfront. Elixir also allows developers to define function signatures and custom types. Function signatures provide a way to document code and can be used with static analysis tools to find discrepancies and possible bugs. Custom types provide a way to explicitly represent concepts in code, making it easier to read and understand.

In this tutorial, the importance of writing clear and concise code to improve readability was discussed, as well as the use of comments and documentation to help with learning. The tools and standards for writing comments and documentation in the Elixir ecosystem were covered. This included module documentation, function documentation, testing documentation, and generating HTML documentation. In the end, it was concluded that although writing documentation is not a favorite task for many developers, Elixir makes it beneficial and easy to do.

This article explored using Mnesia, a distributed, soft real-time database management system, as a storage mechanism for Erlang terms in Elixir applications. It is part of OTP, meaning it can be used without setting anything up and is faster than DETS. It also offers features like transactions and the ability to store data across multiple nodes, though it has the limitations of size constraints and distributed storage. Finally, it allows for direct storage of Erlang terms without translation. The article showed how to start Mnesia, create tables, insert and read data, and concluded that it is ideal for a limited amount of data on a fixed number of nodes, and that it offers the advantage of direct storage of Erlang terms.
Oct 05, 2016
ETS stands for Erlang Term Storage. It is a built-in storage engine in OTP, available in Elixir through Erlang interoperability. It is a key / value store, like Redis, but without the need for a third-party dependancy. In Elixir, you can create tables, add data, read data, delete data, and destroy tables using the :ets module. DETS is similar to ETS, but stores data to disk instead of in-memory. ETS can be used with GenServer to create a todo server which stores multiple todo lists.

The Little Elixir & OTP Guidebook by Benjamin Tan Wei Hao is an introduction to Elixir and OTP that focuses more heavily on the OTP side of things. It covers topics such as setting up the environment, running elixir in iex, data types, pattern matching, processes, and using `GenServer`. The book also includes chapters on building a worker pool from scratch with Mix, GenServer, and Supervisors, as well as covering topics such as distribution, load balancing, fault tolerance, property-based testing, and concurrency testing. This book is a great first step for those who are struggling to understand the bigger picture of how to build Elixir applications and use OTP effectively.
Sep 21, 2016
This article has covered many of the fascinating aspects of Elixir, Erlang, and OTP that allow us to build highly available, fault tolerant applications. It has looked at using Agents, understanding GenServer, using Mix to organize projects, and working with Supervisors. It has then gone on to explain how all of these topics can be combined to build a Casino application. Finally, it has demonstrated how to generate the application using Mix with a top level Supervisor, as well as how to create a Player process and Supervisor to manage them.

This article reviews two learning resources for the relatively young programming language Elixir. Programming Elixir, written by Dave Thomas, is an excellent introduction for newbies, while Elixir in Action, written by Saša Jurić, is a more advanced guide for those looking to become an Elixir developer.
Sep 07, 2016
This article discussed how to use Mix to organize Elixir projects and how to use Supervisors to build highly fault tolerant applications. It explained the difference between monitoring and linking processes, and discussed the concept of "let it crash". Lastly, it provided an example of creating a 'Flakey Service' using GenServer.

Mix is a set of tools for creating, testing, and building Elixir applications. It is packaged with the language and is used to manage dependencies, compile the code for deployment, and to create a new project. Mix also comes with ExUnit, a testing framework. Naming conventions must be followed, such as using a top level module to prevent naming collisions, and files and modules should be snake and camel cased respectively. Mix also allows for umbrella projects which are sets of independent Elixir applications.
Aug 24, 2016
This article examines the use of GenServer in Elixir, a functional programming language, as an abstraction for building generic servers. It follows up previous articles which explored concurrency and parallelism, using tasks, and storing state in Elixir processes. It will discuss the how and why of using GenServer.
Aug 17, 2016
In this tutorial, we looked at storing state in Elixir using processes. Processes allow us to store state inside of a process and access it through message passing. Elixir provides a number of helpers to make this process easier, such as the Agent module. Agents allow us to start a process, update state, and retrieve data from the state. They provide functions for adding, updating, reading, and deleting state, and can be used whenever state needs to be stored and interacted with.
Aug 10, 2016
This article discusses how Elixir processes work and how they can be used to maintain state. It explains that like objects in object-oriented programming languages, processes communicate with each other via message passing, and can be thought of as a way to retain state. It also provides an overview of today's tutorial which will cover working with state and Elixir processes.
Aug 03, 2016
This article discusses the use of the `spawn/1` function and the `Task` module in Elixir to create and execute concurrent processes, as well as their use in supervision trees. It notes that while supervision trees will be discussed in a future tutorial, today's focus is on using tasks.
Jul 27, 2016
Elixir processes are key for enabling concurrency and parallelism which are important for making applications run faster by running tasks concurrently and in parallel. Concurrency refers to when two or more tasks can start, run, and complete in overlapping time periods, whereas parallelism refers to when tasks run at the same time, for example on a multicore processor. In Elixir, processes are separate contexts (isolation) and you can have hundreds of thousands of processes on a single CPU (lightweight). If your computer has multiple cores, Elixir will run processes on each of them in parallel. To collect the results from each process, messages can be sent back with the result of the request.
Jul 20, 2016
This article discusses a book, "Artificial Intelligence - A Guide to Intelligent Systems", written by Michael Negnevitsky. It is for people from all kinds of different industries to gain an understanding of the theory behind artificial intelligence, and how to build and utilize intelligent systems. It is tailored for those without a background knowledge of calculus or experience with programming languages.

Allowing users to reset their password is a common and necessary feature of many web applications. This tutorial will go through the steps to implement password reset using Ruby on Rails and Trailblazer. The process comprises of two separate actions: 1) allowing the user to request a password reset email containing a unique token and 2) accepting the token and a new password. The tutorial will cover setting up the routes, creating a database table, creating an Operation and contract for requesting a reset email, and processing the reset request.
Jul 11, 2016
This article explored the basics of processes in Elixir, including how to spawn a process, send and receive messages between processes, and linking processes together. It also showed how processes in Elixir are analogous to objects in an object-oriented programming language.
Jul 06, 2016
This article covers the importance of integration tests in Ruby on Rails, and provides a tutorial on how to create them for the registration and confirmation flows.
Jul 04, 2016
Comprehensions in Elixir provide syntactic sugar and readability when working with enumerable data structures. The Enum module has the same functions for working with enumerables and comprehensions use similar pattern matching and filters. Comprehensions can also use multiple generators for nested loops and produce any collectable data structure. There is no real difference in terms of performance, but they can make code easier to read.
Jun 29, 2016
This article outlines how to use Trailblazer Cells and Action Mailer to create a confirmation email for a registration process. It explains the concept of Cells, which are View Models that can be used for emails, and references previous tutorials on getting started with Trailblazer Cells and building a user confirmation flow.
Jun 27, 2016
Polymorphism is a concept in programming that allows us to act on something in a generic way without knowing specifically what the thing is. In Elixir, polymorphism is implemented using Protocols. Protocols are like blueprints which define the function, and each type that wants to implement the Protocol also has an implementation that deals with how the Protocol function should be handled. We can define and implement our own Protocols in Elixir, and each type that uses the Protocol must have an implementation for it or it will throw an error.
Jun 22, 2016
This article describes a registration process being built using Ruby on Rails and Trailblazer. It covers how to create a link to confirm a user's email address and how to confirm imported users and give them the opportunity to pick a username and set a password. Trailblazer's abstraction is mentioned as a helpful tool for handling data based on the user's state. The article also provides a tutorial for how to implement this functionality.
Jun 20, 2016
This article looks at Structs and Maps in Elixir, discussing how they are similar and different, and the benefits of using Structs over regular Maps. Structs are an extension of Maps which provide compile-time guarantees and stricter access rules. Structs should be used when the data structure is a known type with properties that are defined up front.

This article explains how to build out an action for creating new users in Culttt using a Trailblazer Operation. It covers how two new routes will be needed, along with a Controller and UserMailer class. It explains how the User::Create::Operation::Default class will be updated to send a confirmation email and how a new Operation for requesting a confirmation email will be created. It also covers how a Cell class and view template will be used for displaying the form and how tests will be used to make sure everything is working properly.
Jun 13, 2016
This article explores the differences between the Elixir `Enum` and `Stream` modules, and explains when and where each should be used in Elixir code.
Jun 08, 2016
The Trailblazer Cells component of Trailblazer allows developers to encapsulate parts of their UI into components, using Object-oriented programming techniques and good practices to create widgets that can be composed and tested in isolation. This is in stark contrast to the Rails way of having an ocean of global helper functions and messy views. Cells provide a way to move the logic from the View into the Cell, and keep the View itself clean and easy to work with. They also provide a way to reintroduce Object-oriented methodologies that have been sucked out of the Rails View layer, and make testing easy by allowing Cells to be instantiated in isolation.
Jun 06, 2016
This article discussed the use of recursion in Elixir, specifically for looping through lists. It provided an example of a module that prints each element of a list, and discussed tail call optimization. It then provided two more examples of recursion, one for doubling each value in a list, and one for only returning the even values.
Jun 01, 2016
This article discusses the use of inheritance in the context of Ruby applications built using Trailblazer. It explains that inheritance is a basic building block of Ruby and is used in several Trailblazer components. It also provides a link to an article that explains inheritance in Ruby in more detail.
May 30, 2016
This article discusses how to use branching and conditional logic in the programming language Elixir. It suggests replacing the classical 'if' and 'else' statements with multi-clause functions and notes that there are no classical loop constructs in Elixir.
May 25, 2016
This tutorial explored how to get started with Trailblazer and Ruby on Rails, including creating an Operation for creating new users, writing tests, adding routes, and creating views. It also discussed the benefits of writing tests first and the spike and stabalise method of writing code. In the end, the tutorial showed how to connect the dots to finish off the implementation for creating a new user using Trailblazer and Ruby on Rails.
May 23, 2016
This article discussed the importance of multi-clause functions and pattern matching in Elixir. It showed how to pattern match the arguments of a function and use multiple definitions of the same function based upon the arguments it was called with. It also discussed the use of guards in Elixir to make the clause more specific. This technique can be used to print a message based upon what type was given to the function.
May 18, 2016
In last week's tutorial, we looked at defining our first Trailblazer Operation for creating new users. Trailblazer Operations encapsulate a given action of the application and take responsibility for accepting data from the request, validating that data, and creating or updating the database. It is possible to define the Contract, which is responsible for the properties and validation rules of the Operation, as a separate class and set it as the Contract for the Operation. This is helpful for Operations that share many of the same properties and validation rules. The Contract is actually just Reform in disguise and is defined with a Base class that can be extended for the create and update actions. The Contract can then be set on the Operation, allowing business rules that should always be satisfied to be placed in the base class.
May 16, 2016
Elixir is a programming language which uses Pattern Matching for a variety of operations, such as assigning values to variables, decomposing Tuples, Lists and Maps, using wildcards, and matching against the contents of a variable. Pattern Matching has many uses and is a unique feature of the Elixir language.
May 11, 2016
This article discusses the concept of Operations in Trailblazer, a framework for managing abstractions in Ruby applications. It builds on a previous tutorial which showed how to setup a Trailblazer project with Ruby on Rails. It explains that Controllers should be lean HTTP endpoints and Models should only deal with associations and querying, and that Operations are classes that encapsulate the business logic of an application.
May 09, 2016
In Elixir, functions are first class citizens which allows them to be assigned to a variable and passed as an argument to other functions. Anonymous functions are called using dot syntax to differentiate them from regular function calls. The & operator is also used when writing anonymous functions and it captures the module name, function, and arity and converts it into a lambda. Closures are lambdas which reference a variable from outside its scope and will still use the same value if it is changed afterwards. Functions as first-class citizens can be used to make functions such as 'map', 'each', and 'reduce' more flexible and generic.
May 04, 2016
This article provides a review of Trailblazer, a book on the "high-level architecture" framework for Ruby web applications. It explains how Trailblazer is decoupled from Rails and provides instructions on setting up a new Ruby on Rails project and adding Trailblazer to it. It also explains the advantages of the Trailblazer folder structure and the benefit of using Trailblazer for new projects outside of Rails. This article serves as an introduction to the mini-series on Trailblazer.
May 02, 2016
In this tutorial, the importance of function arity in Elixir is discussed. Function arity is the number of arguments a function takes, and in Elixir functions with the same name can have different arity, which is useful for providing default arguments. Pattern Matching will be looked at in the next tutorial.
Apr 27, 2016
This article is about Ruby on Rails and Trailblazer, a "framework" for dealing with the complexity of a Rails project. Ruby on Rails provides a wealth of tools to quickly create a functional Minimal Viable Product, but can become a "ball of mud" when the project reaches a certain level of complexity. Trailblazer provides tools for adding abstraction and a methodology for dealing with this complexity. The framework is created by Nick Sutterer, who has also written a book about Trailblazer.
Apr 25, 2016
Elixir is a functional programming language and the Pipe Operator is a useful tool for combining functions and making it easier to read data transformations. The Pipe Operator allows the return value of one function to be passed as the first argument to the next, making it simpler to read and understand transformations.

In this introduction to Elixir, we have looked at Strings, Tuples, and Lists, as well as two associative data structures; Keyword Lists and Maps. Keyword Lists are Lists of Tuples where the first item of each Tuple is an Atom, and they are usually used for passing the arguments to a function or for passing options. Maps are used to store key/value associations, and they are not ordered and you can use any type for the key. Elixir also has a Standard Library Module that provides a number of useful functions for working with Maps.

Tuples in Elixir are a "list" type that can contain items of different values. They are used for storing related data together to form a single aggregate value, and are stored contiguously in memory so getting a piece of data from a Tuple is fast. However, modifying Tuples is expensive as Elixir will copy the whole Tuple in memory and cannot be enumerated. They are often used as the return value of a function, as it enables Pattern Matching and the return value is a known value.
Mar 23, 2016
This is a tutorial on creating a registration process for a Ruby on Rails application from scratch, from creating the Model, Form Object, Controller, View, and writing Unit and Functional tests.

Elixir does not have a dedicated String type, instead Strings are represented as Binaries or Character Lists. Binaries are represented with double quotes, while Character Lists are represented with single quotes. The String Module has a number of useful functions, and Strings can also be interpolated. Heredocs are used for multiline Strings, and are usually represented as Binaries. It is important to understand the difference between Binaries and Character Lists, as they are not interchangeable and you may encounter Character Lists when using an Erlang library.

Active Record objects have a lot of power and responsibility within a Ruby on Rails project, and callbacks can help run specific logic whenever an object is created, updated, or destroyed. Callbacks can be registered with a method or macro style, and can have conditions attached to them. Callbacks can also be extracted into their own class for reuse or isolation. While callbacks can be useful, they should not be used for anything more complicated than modifying data on the object, and should be kept to a minimum.
Nov 23, 2015
In this article, the author explains how to set up Pusher in a Laravel application, including creating a Client to make HTTP requests and a Storage container to store active users. The focus then shifts to authentication for setting up Pusher.

API's are now the cornerstone for application architecture, and should be able to handle complex requests for data. The Pipeline Design Pattern is an excellent way to build up complex queries in a structured and composable way, by breaking the process into individual tasks and passing the query builder through each task. This avoids having messy controller methods with many query options and can be used for middleware. The Query Pipes should have a 'handle' method that accepts the Request and a Closure object, and can be used to set the Account context, add optional filters, and limit the number of results.

Laravel provides a convenient way to resolve environment specific implementations, such as for sending emails or SMS messages. For example, in development you would want to log sending emails, while in production you would use an implementation that actually sends the emails. This saves you from accidentally emailing customers when testing your code. Laravel provides a foundation for this functionality within the framework and you can easily create the same conveniences for your own services and get the benefit of environment-based implementations.
Aug 26, 2015
Test Driven Development is an important practice adopted by many in the Ruby community. Mini Test and RSpec are two popular tools used for testing in the Ruby community and they both provide the same outcome. This week we looked at using Mini Test, and next week we will be looking at using RSpec. To get started, you need to add 'minitest' as a development dependency, create a Rake task to make running the tests easier, create a Test Helper file, and create the first test. Mini Test also has a range of assertions and Spec helpers to make writing tests easier. Testing is an important part of application development and Ruby is a great language to learn how to do it in.

When building an API, it is important to consider what type of authentication to implement. HTTP Basic authentication is an easy choice, but it is quite limited. Oauth 2.0 is a better choice as it is a recognised open standard and is used by some of the biggest online companies. Oauth defines different 'grants' for different use cases and two distinct components, the Authorization Server and the Resource Server. There are a number of existing open source solutions for implementing Oauth, such as the league/oauth2-server package. To use this package, you need to define the table migrations and storage implementations, as well as the Oauth authentication endpoint. After this is set up, you can use the package to generate access tokens and refresh tokens, as well as to grant scopes to control access to the API.

In the last couple of weeks, a task list was built out using Test-Driven Development (TDD). This was done by first creating the list with static HTML, then making it dynamic with a controller and model, and mocking an API server. Interactivity was added to the application by transitioning to other pages using TDD. Tests were written, routes and links were added to the template, models were used to find the task, and Mirage was configured to define the new route. Ember's helpers such as find, click, and currentURL were used to create the interactivity.

Ruby is a programming language that allows developers to use Mixins to allow a class to inherit functionality from multiple places. Mixins are Modules that are included into a Class and can be Class Methods or Instance methods depending on how they are added. Mixins are a great way to share functionality between different classes without repeating code, while Inheritance is better for suggesting specialization. Understanding the difference between using Mixins and using Inheritance is important for writing effective code.

Ruby is a powerful programming language that allows developers to reopen any class and change its methods. This can be dangerous as it can lead to difficult to track down bugs, but it can also be useful if used carefully. An example of monkey patching is the ability to add or modify existing methods on a class. Monkey patching should be used sparingly, as it can lead to unforeseen issues. It is best used to add convenience methods or when patching a class you own.
Jun 15, 2015

We looked at how to define models, attributes, and relationships as part of Ember Data. Models are important to encapsulate the logic concerning persisted data.
May 13, 2015
This article has looked at the differences between blocks, Procs and lambdas in Ruby. Blocks are chunks of code that can be passed to a method, whilst Procs are blocks that are saved to a variable. Lambdas are anonymous functions that behave like methods and expect exact arguments, whereas Procs will default to nil when arguments are not passed. The return statement is also handled differently, with a lambda returning execution to the enclosing method, and a Proc jumping out of itself and the enclosing method. It is important to understand these differences as they will help you to better understand other people's code.

A Struct is a simple class object that allows you to encapsulate attributes and accessor methods without having to explicitly define a class. Structs can be useful for modelling known things in the domain of an application and are useful for when you need to be more explicit with structured data. They are similar to a Hash but require specific attributes, whereas a Hash will accept anything. OpenStructs sit in the middle of the Hash / Struct / Class spectrum and do not require attributes to be defined beforehand.

Feb 23, 2015
In this tutorial, we looked at building the Application Service for the user registration process of the Cribbb application. The Application Service acts as the "public API" to the inner core and should accept requests, return responses and be agnostic to where those requests come from and where the responses are sent. The Application Service also validates incoming data, dispatches Domain Events and returns the response in a generic format. The Application Service can be injected into a Controller or a Command Line tool to be used for registering new users into the application.

This series is focused on building an open-source application called Cribbb. The majority of the code so far is written in the Domain Layer, but now that Laravel 5 has been released, it is time to build out the Application Layer. This layer will provide an agnostic interface between the Domain and the HTTP layer, allowing the application to be driven in multiple different ways. The Application Layer consists of Application Services, a Command Bus, and a JSON transformation layer. Although this layer is useful in bigger applications, it is not necessary for simple ones. The series will go over each of the Domain layers to build out the Application Layer.

Domain Driven Design does not promote a single architecture style for all applications, as all applications are different. Hexagonal Architecture and Service Oriented Architecture are two examples of architectural patterns, and Command Query Responsibility Segregation (CQRS) is another. CQRS separates reading and writing into two models, allowing for efficient querying and scaling, as well as a task-based user interface. It is best used when there is an imbalance in responsibility between reads and writes, or when complex data processing is required. CQRS is not appropriate for most applications, but it is important to be aware of it as a solution for certain specific problems.
Jan 12, 2015
This article discusses Markdown, a lightweight formatting tool for text that can be converted to HTML. It looks at how large websites like GitHub, StackOverflow, and Reddit use variations of the syntax, and how a service can be created to parse Markdown and extract @mentions. It also looks at how this can be used to send user notifications and auto-link user profiles.
Jan 07, 2015
Service Oriented Architecture is the solution to a difficult problem when it comes to large applications. It involves breaking an application into separate services, each of which provide a common process to be consumed by other applications or areas of the organisation. It can be useful for integrating legacy or third-party systems, but it also can be used when an application has outgrown its single codebase. However, it should be avoided unless it is absolutely necessary, as it can become a nightmare if implemented prematurely.
Jan 05, 2015
This article discusses how Aggregates are an integral part of Domain Driven Design, serving to protect the internal implementation of the application from the outside world. It also looks at how Aggregates can be used to enforce business rules and how they can act as a gateway to the functionality of an application.
Dec 31, 2014
Hexagonal Architecture is an application architecture that promotes the separation of concerns through layers of responsibility. It is agnostic to the outside world, enables easier testing in isolation, allows for the replaceability of ports and adapters, and provides a separation of the different rates of change. It also encourages a more independent approach to external services. The drawbacks include a higher level of complexity, the cost of indirection and isolation, and the fact that most web applications do not need the level of complexity.
Dec 29, 2014
This article discusses how Domain Driven Design can be implemented using object oriented programming, specifically in PHP. It explains how the instantiation of an object is an important part of its lifecycle and provides an opportunity to implement business logic and enforce the rules of the application. It also looks at how Aggregates group related Entities into a single unit to provide a constrained and unified interface.
Dec 24, 2014
Factories are objects that are responsible for creating other objects, and are commonly used in object-oriented programming. They provide standardization and encapsulation when creating complex objects, and should not be responsible for their own creation. In Domain Driven Design, Factories form an important part of the application's domain, and provide an interface that reflects the goals of the client. When designing the interface of a Factory, it is important to accept everything needed to create the object in a single interaction, and to decide how problems should be handled if the invariants of the created object are not satisfied. Entities and Value Objects have different requirements when it comes to Factories, and Factories can also be used to reconstitute stored objects.
Dec 22, 2014
This article is part of a series on building an Open Source application called Cribbb. This particular post looks at using Entities in different Bounded Contexts to add structure and prevent responsibility from leaking outside of that context. The article discusses the need for a new Bounded Context for the Discussion functionality of Cribbb, identifies the important concepts, outlines the division of responsibility, and discusses the objects that need to be built. It emphasizes the importance of planning and designing before jumping into the code.
Dec 17, 2014
Domain Driven Design is a way of managing the complexity of applications when the web of interconnected entities and associations becomes overwhelming. Aggregates are a way to resolve this complexity by clustering associated objects into a single unit, with the root entity as the only globally accessible object. Aggregates have several benefits, such as providing a simple interface, maintaining invariants, and allowing safe removal of objects. Consequently, thinking about code in terms of Aggregates can be useful in resolving the complexity of a project.
Dec 15, 2014
This article discusses the importance of using entities in bounded contexts within an application as the application grows in scope. It explains that when an application is small, having all objects within reaching distance is easy to work with but as the application grows, there needs to be a rethink of the structure to accommodate the new design and requirements. The article emphasizes the importance of entities in an application as they have a lot of power and responsibility, making it essential to have the right structure in place.
Dec 10, 2014
Modules are an important concept in Domain Driven Design, used to keep related classes under the same "bucket" and prevent name collisions. They should be derived from the Ubiquitous Language and contain one or more cohesive Aggregates, organized by the Domain rather than the type of class. Modules should also be loosely coupled and can be organized into different layers. While it is possible to make them separate Composer packages, this is usually more trouble than necessary.
Dec 08, 2014
This article discusses the concept of Domain Driven Design and how important it is to encapsulate business logic within Domain Objects.

They then explain the role of the Identity Bounded Context, which is important for consumer social applications. Finally, the author introduces the role and responsibility of Groups, which will be the next Bounded Context discussed in the series.
Nov 26, 2014
This article looked at two important topics in Domain Driven Design: Domain Models and Bounded Contexts. Domain Models are the focused knowledge around a specific problem to the business, and Bounded Contexts are the boundaries around a Domain Model. There are a number of technical ways to integrate Bounded Contexts, third-party services and legacy applications. This article discussed seven integration strategies, including Shared Kernel, Customer/Supplier, Conformist and Anti-Corruption Layer, and the pros and cons of each.

This tutorial is about implementing the Twitter follower model using Doctrine. It explains the concept of the Owning Side and the Inverse Side of a bi-directional relationship, as well as how to create a Many-to-Many, Self-referencing relationship. It also explains how to create methods that allow users to follow and unfollow each other, and how to test them.
Nov 19, 2014
Using Domain Driven Design, it is possible to break down large problems into smaller, more manageable parts. This helps to better understand the nuances of the problem by providing a more focused language. A Bounded Context is the boundary that surrounds a particular model, keeping the knowledge inside consistent while ignoring noise from the outside world. A Context Map is a global view of the application that shows how Bounded Contexts communicate and share data. It is important to have both these tools in order to properly understand the problem and create a successful application.
Nov 17, 2014
In this article, it is suggested that web applications should have multiple layers of validation instead of relying solely on the Domain layer. These layers include client-side validation, Application Service requests, Framework validation libraries, and the Domain layer. It is argued that while Don't Repeat Yourself is an important rule, sometimes repeating yourself can make the code easier to work with and understand. The Domain layer is seen as the final guard against invalid data, but not the only one.
Nov 12, 2014
Domain Driven Design is an approach to software development that focuses on solving business problems. The Domain Model is the structured knowledge of the problem, which includes the vocabulary and key concepts of the problem domain, and the relationships among all of the entities within the scope. It is important to have a Domain Model because it is the backbone of the language used by all team members, it helps shape the code written, and it is a source of truth for the project. It is created through an iterative process of collaboration between the business experts and the technical team.
Nov 10, 2014
This article covers the three different layers of Domain Driven Design (DDD) application architecture: the Domain layer, Infrastructure layer, and Application layer. The Domain layer is responsible for encapsulating the application's business rules, while the Infrastructure layer is responsible for technical details of how the application is implemented. The Application layer acts as a public API to the application, and can be implemented in two ways: Application Services, or a Command Bus. Application Services tend to be more complicated, while Command Buses are simpler but harder to test. The Command Bus is made up of three components: Commands, Handlers, and the Command Bus itself. The Command Bus also requires an IoC Container and Inflector to map Commands to Handlers.

Implementing Domain Driven Design is a book written by Vaughn Vernon, a highly regarded software engineer with more than twenty-five years of development experience. It builds upon the theory of Eric Evans' "The Blue Book", Domain-driven Design: Tackling Complexity in the Heart of Software, which pioneered a new approach to application development. Implementing Domain Driven Design offers practical guidance on how to apply the tools and techniques of Domain Driven Design in real world projects, as well as covering new Domain Driven Design related material that has surfaced since the first book was published. The book follows a team of developers as they are tasked with creating a series of new applications, giving the reader an inside look into the reasoning of how certain decisions are made and how the team got to that solution. Experienced developers with a good grasp of Object Orientated Programming will benefit from reading both books.
Nov 03, 2014
In this article, the author discusses the need to sometimes write your own Domain Event Dispatcher instead of using an existing Open Source package. The Dispatcher, Event, and Listener interfaces are discussed, along with the process of registering and dispatching Events. The author also talks about what goes in to a Domain Event and the challenges of testing Domain Events.

Domain Driven Design is a framework for tackling complex software projects to deliver an end-product that meets the goals of the organisation. It promotes focusing the project on an evolving core model, and a collaborative feedback loop that concentrates on solving the organisation's primary requirements. It is written by Eric Evans, a well respected consultant, and is not about a single technology. Common reasons why projects fail are lack of communication between the business experts and the developers, developers failing to understand the problem they are solving, the code not reflecting the real world problem, and not being able to refactor the code. Domain Driven Design emphasizes the importance of the ubiquitous language, communication, and how to effectively become a project leader. It is aimed at experienced developers, and is a revelation for those already familiar with a lot of the code examples, design patterns and terminology.

Domain Driven Design is an approach to programming that involves breaking up an application into three main areas: the Domain, the Infrastructure, and the Application. Each service layer has a strict set of responsibilities, and should not be concerned with operations outside of their line of responsibility. Domain Services model functionality derived from the application's ubiquitous language, while Application Services handle requests and responses from the outside world. Infrastructure Services are used to abstract the technical details of the application, such as message queues, email providers, or payment gateways. These services should each implement an interface that acts as a contract, and the application code should depend on the interface contract rather than the concrete implementation. This allows the application to remain insulated, and makes testing the code easier.

Domain Driven Design is an important concept that models domain logic through Entities and Value Objects. Domain Services are used to encapsulate logic that does not fit neatly in either of those objects. The purpose of today's article is to look at when and how to use Domain Services. It should be noted that overusing Domain Services can lead to the Anaemic Model problem, where the logic has been robbed from the very objects that need it most. Domain Services should be stateless and they should only be used if the responsibility of the action does not fit on any existing Domain Object. Different types of Service exist for each layer of an application, and it is important that the implementation of a Domain Service is separated from the Domain, such as using an interface.

Domain Driven Design is a technique used to understand the requirements of an application and model it in code. It aims to mitigate the problem of business and development sides failing to communicate effectively by using Domain Events, a pattern which decouples actions from their triggers. Domain Events are classes which model a particular part of the domain, such as sending a confirmation email to a new user when they sign up. Event listeners are then registered to fire when the event occurs, allowing for decoupled code. Event dispatchers are used to trigger the listeners and the Domain Events package is used to facilitate this. Domain Events should be used to model the events of the application's domain and should be kept separate from data persistence or framework concerns.

This article continues to discuss how to create an Active Record-style PHP SDK package. It covers how to normalize the raw JSON responses from an API, as well as how to handle instances of single and multiple entities, as well as parent and child entity relationships. This normalization process will be implemented in a 'Normalizer' class.
Sep 15, 2014
An important part of the beauty of Domain Driven Design is the fact that it provides a language to describe certain concepts and components within applications. Terms like Aggregate Root, Value Object and Entity have concrete meanings and are used to describe how applications are formed. Additionally, it is important to represent these concepts explicitly in the code written to ensure that the application's domain model is correctly represented. To do so, foundational layers of objects, interfaces and traits can be used throughout the project to make the domain related code more expressive. This helps to reduce confusion in application development and to make the code more readable.

This article explains how to create a Normalizer class in PHP to transform JSON payloads from a third-party API into model instances. The Normalizer class will accept an instance of the current model to know what type of model the payload should be transformed into. The Normalizer class will have two public methods for transforming a single entity or a collection of entities. The code for the class is provided and it is explained that testing a few smaller classes is easier than testing one big class.

In this tutorial, the author looked at setting up the foundation of being able to query the CapsuleCRM API by separating the querying functionality into its own directory and splitting each querying action into its own trait. They then created a convention of inferring the API endpoint, with local configuration being able to override this. The author then wrote tests for the find() and all() methods, and created a Findable trait to add the ability to query to a model class. Finally, they implemented the FindOne and FindAll traits.
Aug 25, 2014
In this week's tutorial we looked at how to use The Specification Pattern to encapsulate the business rules of object selection within our applications. This pattern is powerful because it allows us to define a single responsibility class that can be combined with other Specifications to meet complex requirements. We also wrote two tests for a UsernameIsUnique Specification object, which returned a boolean value depending on if the username was found in the database or not.

This article is part of a series exploring how to integrate Doctrine 2 into a Laravel project and the unique characteristics and functionality Doctrine 2 offers. It provides an overview of the Data Mapper pattern and compares it to the Active Record pattern and explains the seven topics covered in the series so far. It also emphasizes the main reason to choose Doctrine 2, which is to encapsulate the business rules of an application.
Aug 13, 2014
This article discussed how to use the Factory Method Design Pattern to create an Active Record style PHP SDK. This pattern allows us to hide the complexity of instantiating certain objects whilst also ensuring that every instance of that object will be created in the same way. The author then provided a code example of how to create a Factory object and wrote tests to ensure that it works as expected. Finally, the author concluded by noting that while a developer is free to bypass the factory and instantiate objects directly, in future tutorials they would show how to put further restrictions in place to ensure that the dependencies that are required can't be forgotten about.

Doctrine Filters are a useful feature in Doctrine 2 that allows developers to apply a clause to a query regardless of where the query originated in their application. Filters can be used to filter results, such as to remove spam comments or to mark certain users as deleted without actually deleting them from the database, or to implement business rules, such as to only show results related to the current client. Filters are registered with Doctrine's configuration and can be enabled or disabled as needed. The drawbacks of using filters is that business rules should be articulated within the domain of the code, not the ORM, as the ORM is replaceable.

This tutorial looked at implementing validation for a third-party API in an Active Record style PHP SDK. Validation enables us to protect the sanity of the data that is allowed across the boundary from the user to the application. The tutorial looked at different validation libraries, and chose siriusphp/validation due to its small number of dependencies and ability to define validation rules as an array. Tests were written to ensure the validation was working, and a reusable trait was created to make it easy to add validation to the relevant models.

Doctrine 2 is a popular database library with an event system that can be used to trigger certain actions in response to something else happening within the system. Examples of this could be keeping an "updated_at" field up-to-date when a record in the database is changed, or sending an email when a new user registers for an application. Doctrine 2 has two ways of implementing this functionality: Lifecycle Callbacks which are methods on the entity, and Lifecycle Event Listeners, which are dedicated objects. For example, a "SendWelcomeEmail" listener could be triggered on the "postPersist" event to automatically send an email whenever a new user registers.

Models in the Active Record pattern are important because they provide a public interface for working with entities and the storage layer of an application. They are responsible for reading, creating, updating and deleting from persistence storage, as well as accessing properties and relationships of the record. Models may be considered "fat models" due to their responsibility, but this is not a concern for this series of articles. In this tutorial, the first steps towards building out models for a PHP SDK package were taken, by setting up the abstract model class that will hold a lot of the responsibility of each model instance.
Jul 21, 2014
This article examines how to use Doctrine 2 to create relationships between entities. It explains that entities in Doctrine 2 are plain PHP objects and have annotations to map them to a database. It also discusses how to create database schemas by reading the entity class.
Jul 16, 2014
The Active Record pattern is used to tightly couple the persistence layer to the entity, allowing for easy create, read, update and delete. When not using a traditional ORM, a HTTP Client is used to query and persist the entity to a third-party API. Guzzle is a popular PHP package used as the HTTP Client and dependency injection is used to ensure the code can be tested in isolation. The Connection class is used to instantiate a new instance of the Guzzle Client and define methods for GET, POST, PUT and DELETE. Tests are written to ensure the Client is created correctly.

Jul 07, 2014
This article explains the differences between Doctrine 2 and Eloquent, how to use Doctrine 2, and the advantages it has over other ORMs. Doctrine 2 is an ORM that implements the Data Mapper pattern and is more faithful to the repository pattern than Active Record ORMs. It uses annotations within the entity and has a service class known as the Entity Manager that is responsible for all persistence logic. It also uses the Unit of Work pattern and the Identity Map to efficiently query the database. The Doctrine Query Language is a powerful tool for complex queries. While Doctrine 2 is great, it is only best suited for certain types of applications and should be used pragmatically.

Reflection is a powerful tool in software development that allows objects to introspectively examine themselves at runtime. It is useful for debugging code and creating documentation, as well as for creating dependencies in frameworks such as Laravel. Common PHP Reflection functions include get_class(), get_class_methods() and method_exists(). The Reflection API also offers a number of classes and methods for further inspection of objects. Laravel uses Reflection to automatically inject dependencies into classes.

PHP has single inheritance, which means a class can only inherit from one other class. To prevent code duplication, developers may wish to inherit from multiple classes. PHP 5.4 added a feature called Traits, which are like Mixins and allow a class to "mix in" Trait classes, reducing code duplication and avoiding the problems of multiple inheritance. Traits are beneficial for reusing code between similar classes, but they can lead to bloated classes with too much responsibility if used incorrectly. Interfaces are contracts that say an object is able to do something, while Traits give the object the ability to do the thing. Typical situations for using Traits are when avoiding complicated class inheritance, or when copy and pasting code between similar classes. Traits should not be used as a crutch and composition may be a better option.

CRUD (Create, Read, Update and Delete) are the four basic functions that are used in most web applications. These functions allow for data to be stored in persistent storage such as a database. Laravel offers a great foundation for these functions, but it can be difficult to understand the boilerplate code needed to use them. This tutorial provides an example of how to create the basic code for CRUD operations, including routes, controller methods, and views. The controller is first injected with the repository, then the index, show, create, store, edit, update, delete and destroy methods are implemented. The tutorial also outlines the views needed for each method, as well as the forms and flash messages.

An ORM (Object Relational Mapper) is a layer that sits between a database and an application and is responsible for transforming data in the form of objects into relational data that can be stored in a database and vice versa. There are two main implementations of an ORM: Active Record and Data Mapper. Active Record is popular and intuitive, but Data Mapper is better for encapsulating domain rules and procedures of a business. The type of application, the environment it is built in, and the business rules should be considered when deciding which pattern to use.

Exceptions are a useful tool for programming languages because they allow developers to detect errors and address them gracefully. Without exceptions, applications would present errors to the user and it would be more difficult to diagnose what went wrong. Though exceptions may seem daunting, they can be easily learned and used to make code better and life easier for developers. Exceptions should only be used in exceptional circumstances and when dealing with external problems or package API's. Best practices include only using exceptions in exceptional circumstances, not using exceptions to control logic, and using custom exceptions to deal with errors in specific ways.
Apr 07, 2014
This post discussed the various ways of managing configuration data in a Laravel application. It covered setting up the configuration files and environment, using the Config facade, service providers, and dot files.

Interfaces are contracts that ensure that any classes that implement them will always have a defined set of methods available. They are distinct from Abstract Classes in that Interfaces state that the object is capable of doing something, while Abstract Classes state that the object is an instance of something. Interfaces should be used when writing code as part of a larger application, as it provides a public API to the code and ensures architectural integrity. They are also important for working in teams, as other developers don't need to care about the implementation details.

Multi-tenant applications are applications where one single application is used independently by many different clients. When a client authenticates with the application, they can only access and view the data that they have created, and cannot view data that was created by any other clients. Multi-tenant applications have become increasingly popular due to the rise of Software as a Service and the move towards delivering applications through the cloud. In this tutorial, the author walks readers through setting up the core components to allow them to create multi-tenant applications in Laravel 4. The author also explains the three different approaches to multi-tenancy, and how to create the Context interface and implementation. The Context is then bound in the IoC container, and set when authenticating. Finally, the Tenant Repository is created to scope the database queries.

Abstract classes are an important part of Object Oriented Programming languages that enforce standards and reduce duplicate code. They act as a blueprint that should be extended by child classes, and not used directly. Child classes need to implement the same methods and properties that the abstract class defines. Abstract classes should be used whenever you have multiple implementations of a certain functionality, as they ensure that each child class is interchangeable with one another by always having a consistent public API.
Mar 24, 2014
Laravel 4 is a modern PHP framework that is built on the principles of high quality application design. It is equipped with an IoC container, which is an integral part of the framework. This IoC container is used to resolve objects and dependencies, and it allows developers to easily switch out components and mock dependencies. The IoC container is also responsible for running Service Providers and resolving objects automatically, without the need for developers to manually set it up. Finally, the same concepts of Inversion of Control and Dependency Injection are applicable in many different frameworks and programming languages outside of Laravel and PHP.

The Factory Method Design Pattern is a way of controlling the creation of classes. It allows code to be kept DRY and ensures consistent behavior. It is often used when needing to create many interchangeable solutions for a given problem, such as database connections or payment gateways. The Factory will take an argument and try to create an instance of the appropriate class. It is an excellent solution for managing pluggable "drivers".

Laravel 4 is a modern PHP framework that is built around an event-based architecture, which makes it easily extensible and maintainable. Events make it possible for developers to listen for and respond to certain events in their applications. It also allows developers to create their own events for their applications. Using an event-based architecture helps to separate concerns, making code easier to maintain. Events can be fired and listened for using closures or classes. Queues can also be set up to process events. Laravel's core is built around an event-based architecture, so developers can take advantage of this to extend the framework.

Jeff Bezos, founder of Amazon, is renowned for his quote "Your margin is my opportunity", which refers to Amazon's strategy of cutting the margins of existing companies in order to offer lower cost alternatives to consumers. This strategy has been applied to many industries, and Amazon often loses money in categories in order to remain competitive. Amazon has also challenged Apple and Google with their Kindle range, with a focus on selling services and content to the consumer rather than hardware and advertising. Unbundling high margin industries is a great way to reduce complexity and provide a better service to consumers at a lower price. Companies such as iTunes, Netflix and Airbnb have all successfully taken advantage of this shift, and startups have the opportunity to reinvent the pricing structure of their industry.

Over the past 10 years, the trend of the Internet has shifted from static websites to real-time applications and services. Nearly all new websites have some sort of real-time service component, such as an API or webhook. An API is used to ask a direct question to another application, while a webhook is used to be notified when certain events take place. Webhooks are incredibly easy to create and are used by companies such as MailChimp, SendGrid, Stripe, and Shopify to keep other parts of their services up-to-date.

When building a new product, it is not uncommon to have it fall flat after launch. To recover from a product launch that no one cares about, the first step is to take a step back and assess the situation. Evaluate the true value of the product, what people are actually using, and what could be removed. It is also important to find people to talk to and understand their problem, and work with them to sign up and use the product. Lastly, failure can be beneficial since it is a quick way to discovering the truth. However, it is important to manage risk by making small bets and little failures.

The consumer Internet is a competitive place and many applications are trying to figure out how to make money. Advertising is the most common way to monetise an application, and while this method can be successful, it can be difficult to compete against giants like Google and Facebook. Subscription and in-product purchases are also potential monetisation methods, but they have their own drawbacks. Aggregate data insights may be a better option to monetise consumer applications, and this method involves offering free use of the service while collecting data and selling insights to larger companies. To create an aggregate data business, steps include creating a service that generates passive data, offering a low-cost premium service, blogging about data, building tools to leverage the data, and selling aggregate data and insights.

Online products have become increasingly sophisticated and well designed in recent years, but many companies struggle to get their product recognised and adopted by the mass market. Distribution is an essential component for a successful and sustaining company, and traditional online distribution methods have both positives and negatives. Companies can build their own distribution channel by investing in an additional product that can generate inbound interest and cultivate customer relationships. An example of companies that have done this successfully is Thrillist and Birchbox. Building your own distribution channel has benefits such as owning the relationship with the customer, being able to adapt to changes in the market, and being able to prevent competitors from using it. This strategy can be seen as a marketing expense, as it is a long-term investment that can drive targeted customers to the product.

The four steps to persuasion is a framework that can be universally applied to any situation where you need to "sell" an idea, such as selling a product or convincing a manager to take action. The four steps are: recognizing a pain, creating a solution, describing the benefits, and showing how the pain compounds over time. Recognizing a real pain is the most critical step, as customers won't switch products if there is no perceived problem. When selling a product, it is best to focus on the immediate benefits. Lastly, if you have an idea for solving a problem, use the four steps to persuasion to make a strong case for your manager to allow you to step up and solve it.

Gaining traction for online products is becoming more and more difficult due to the sheer amount of competition. Partnerships offer an opportunity to access an already established audience and added value.

The Long Tail is a book of research by former Wired Editor-In-Chief Chris Anderson, which examines how the Internet has enabled the rise of niche content, allowing for the proliferation of media from many different sources. This has disrupted the traditional hit-based business model, as consumers can now explore their own interests and tastes without the influence of gatekeepers. The Internet has also democratized the tools of production and distribution, allowing anyone to become a content producer and find an audience. This has created an abundance of choice, but paradoxically, too much choice can be overwhelming and can lead to a decrease in purchases. The Long Tail has changed the way we consume media, with niche content competing with mainstream content for the same audience.

Freemium is a business model where a product or service is provided free of charge with the option of upgrading to a paid version with extended features or increased usage. It is an attractive option for product developers because it reduces the barrier to entry to a product, allowing customers to try for free. It works because the revenue generated from the small percentage of paid users is enough to sustain the usage of the entire user base. There are several variations of the Freemium business model, including advertising support, limited time or usage, and virtual goods in-app purchases. This model has been successful for companies such as DropBox and Evernote. Freemium works best when the product has universal appeal with a large market, an incentive program to encourage user acquisition through Network Effects, and when the product DNA fits well with the model.

Social media is an important opportunity for businesses of all sizes, however many businesses do not properly understand the etiquette of how to interact online. Spamming, expecting people to care about your business, relying on interruption marketing and expecting to make enterprise sales through social media are all fallacies that should be avoided. Raising awareness, offering support and engaging, and becoming useful are all far more effective strategies for businesses to pursue on social media. Habits, saved searches, and scheduling content are easy ways to improve social media engagement without a lot of hard work.

The Viral Coefficient is an important metric for growing a website or application. It measures the exponential growth of users by tracking the average number of referrals that your user base sends out and the percentage of referrals that took the desired action. To calculate your Viral Coefficient, one must multiply their current number of users by the average number of invitations or referrals sent out and find the percentage of referrals that took the desired action. Having a positive Viral Coefficient means you can acquire new customers for free and your product will grow exponentially. Viral Cycle Time is also important as it is the number of steps a user needs to take in order to share your product. Improving your Viral Coefficient requires testing and optimizing to find the most successful referral campaigns and testing the variables of each test. Additionally, offering the sharing user and the new user a benefit or a reward for sharing or recruiting new users can help grow your product virally.

Thirdly, it is important to think about how the app is taking advantage of the hardware and software of the device, and whether it is necessary to be an app as opposed to a website. Finally, it is important to remember that success is rare and failure is common, and one should be prepared for this.

In order to be perceived as a leader within an industry, it is important to become synonymous with a word or phrase that represents that industry. Companies such as Heinz, Porsche, Facebook, Google, GMail and eBay have all become so ingrained in the collective mind of their consumers that they have become the undisputed leaders in their respective industries. This has been achieved by providing a better product than the competition, as well as creating a unique vision of the company and product. Becoming synonymous with a key word or phrase is incredibly hard to achieve, and only one company can own a word. It is therefore important to find an unoccupied territory and become the leader in that niche.

Creating a successful business website requires a strategy for the home page and how it aims to convert traffic into sales. Without a goal and strategy, the home page can become aimless and detrimental to the performance of the website. The goal should be ambitious enough to add real value to the bottom line of the business.

Website Optimizer can be used to set up experiments to serve sections of traffic with slight differences in the page. User personas should be created to better understand the needs and desires of different subsets of the audience.

Apple is currently positioned to disrupt the entertainment industry and Hollywood, as no other single entity has the infrastructure, penetration and resources that Apple do. The Internet has disrupted both Hollywood and the Television networks, allowing for peer-to-peer networking and services such as Netflix, Hulu and Apple's iTunes. However, consumers are left with a fragmented marketplace of choice between different competing services which fails to deliver the entire breadth of the content available. Apple's integrated system, where they have control over the hardware, software and the entire infrastructure of content, is far more elegant than any other competing proposition. It is in the consumers best interest for a single player to take the lead in disrupting the huge incumbent entertainment industry, and it may be Apple who emerges as the clear victor.

It is permission based and opt-in, meaning that customers are more likely to convert to paying customers, and it is far more engaging than social media posts.

Developing a product online has become much more attractive in recent years due to changes such as the rise in Internet services, venture capital, and low hosting and bandwidth costs. Despite this, many products fail to achieve success. One of the possible reasons for this is the transition from a fad to a utility. A utility is something that is useful, profitable, and beneficial, whilst a fad is a short-lived craze. To make the transition, a product must add value to the user's experience. Examples of products that have made the transition from fad to utility include Foursquare, eBay, and Facebook. To do this, product managers must objectively look at user engagement data and make decisions about the future of their product.

This article discusses the benefits and drawbacks of three different types of user authentication systems for web applications: traditional sign up, through an existing social graph, or an open platform like 4chan. Traditional sign up allows for data collection to target advertising, but can cause friction. Social graph sign up can piggy back off existing user relationships, but lacks the ability to build value within the application. No sign up or pseudo-anonymous systems have less friction, but can result in more spam or bad content.

In 2011, the smartphone industry saw Apple and Android gain significant market share at the expense of BlackBerry and Windows Mobile, leaving the incumbents with an almost impossible hill to climb. This was largely due to the early success of RIM's BlackBerry, which popularized mobile productivity, and the later rise of the iPhone and Android phones which focused on consumer utilities. Microsoft and RIM attempted to fight back, but failed, leading to the suggestion that Microsoft should acquire RIM in order to create a stronger challenge for the Enterprise market and stave off competition from Apple and Android.

The "start up" bubble created by companies like Facebook and Twitter and the movie "The Social Network" has caused an influx of people from other industries who want to join the start up movement. Those with backgrounds in business, finance, law, or other traditional industries often view the creation of a start up differently from someone with a technology based background. Knowing when to pivot, restart, or quit is critical to success. People without a technical background are less likely to understand when to do this, and the dangers of not knowing when to quit can include building a sophisticated product nobody uses, or being unable to reach the desired scale. To know when to quit, founders should track key metrics and have someone with a strong technical background to provide honest feedback.

Foursquare pioneered the Brand partnership business model which combines geolocation, rewards and real time intelligence of customers. This has led to many new start-ups attempting to imitate this model, but most will fail due to lack of engagement. Foursquare has been successful due to its features, partnerships, and user base.
