Based on Are we web yet?, Rust is ready for web development. There are a lot of frameworks available. Most are to build backend services, but some are to develop frontends. That is right, you can write your next single-page application in Rust.
Rust’s standard library is small. It was designed to be. This is why some functionalities appear to be missing and some snippets feel long. Let’s see how extension methods can help.
Applications that interact with databases have a few moving pieces to keep in mind. Between the connection, the setup, and the queries, there is enough to find it overwhelming. This post will cover all those pieces in a Play application.
Building a single page application is a luxury not everyone can afford. If you are short on time, don’t learn Vue.js, React, or the other flavor of the month. Use Play Framework’s built-in templating engine, Twirl. It isn’t perfect but gets the job done.
Play Framework is a simple way to get started with Scala. My first post was a traditional “Hello, World!”. This one will show how to build a ReSTful API for a pet store.
Scala is a language stuck between two worlds. The FP world attracts many talents, but the OOP one is often where people start. My “taming cats” posts covered cats for the first group. Bellow is the start of a few posts on the Play Framework for the second.
Amazon S3 is a great way to host files. It is similar to Google Drive, Apple iCloud, and Microsoft OneDrive, but for developers. Files are uploaded into Buckets under specific Keys. They can then be downloaded from around the world. There is a little bit more to it, but that is the main gist.
Disclaimer: The solution bellow works, but there are many cut corners. This is because I am learning Rust. Don’t hesitate to improve my solution in the comments, or on GitHub.

Running virtual private cloud, or VPC, on AWS is common, and even required in some cases.
The third one down the list is Monad.
Continuing with scary names, Applicative is next.
Computer science is great at finding off-putting vocabulary. It is able to hide simple concepts behind scary words, for example, Functors.
Scala supports supertypes and typeclasses. Those allowed me to write a generic maxOption function, in a previous article. With the overview out of the way, I will show in more detail how typeclasses can add real value to your project.
After a few months of writing about Cats, it is great to take a small break. This pause isn’t to start anything new but to build foundations for the upcoming posts. If you are looking to learn about those scary FP words, you will need to understand what is below.
Cats is a library which provides abstractions for functional programming in the Scala programming language. The name is a playful shortening of the word category.

There are plenty of options to host static websites. An obvious one would be GitHub pages. This can deploy pages found in a directory, or found in a branch. It is great if you have a public resource to publish, but it can’t handle private ones. For those cases, I would recommend AWS S3.
Exercism is a nice little service I talked about last month. It is great to learn new languages or improve your skills, but it isn’t perfect. I wished it had submission validations. So let’s build one.
I often get distracted by new things to study. Some are rather old, Erlang, Haskell, and others are fairly new, PureScript, Rust. I am not looking to master these skills, but at least understand how to use them.
I haven’t played with embedded systems since college. My group and I built a wonderful little vehicle. It could follow a line, traverse an obstacle course, and pick up balls along the way. Pretty standard for a college project, but still quite fun to build.
Your source code is important. It defines everything about your application. How it runs. How it tests itself. How it gets deployed. A bad commit, at best, could take your application down, at worst, open access to your whole system. Why not monitor your repositories and avoid those issues?
Shrove Tuesday is over. After eating my weight in pancakes, I had a longer look at the recipe.
Last month, I covered how to use AWS CodeBuild as a continuous integration solution. It finished with a simple example of continuous deployment. AWS supposedly has a better solution, AWS CodePipeline. Let’s see if this is true.
Travis CI, Circle CI, and many others are great services. They help people create pipelines to build, test, and, if they wish, deploy code. They shorten the development loop, but they do come with their limits. To avoid confidentiality and security headaches, let me introduce you to AWS CodeBuild.
Passwords make the life of your users difficult. Good ones are hard to remember, even harder to type, they should be unique and changed frequently. The only solution seems to be a password manager like 1password, or lastpass, and a strict routine. It’s time to change this, let’s build something better.
