Rust Dependency Management with Cargo

This past week, I started learning Rust. While I have enjoyed learning about Rust’s clever approach to system programming, I have to say that I found its dependency management a bit confusing at first. Today, I will share my new understanding of this with you, whether you are a new, experienced, or aspiring Rustacean.

Write Better Functions

Functions are the building blocks of many applications. Most software developers, current or aspiring, have some experience writing functions. Everyone writes them differently, and there are different approaches to getting the most out of your functions. Bad functions are hard to maintain, more unstable, and lack reusability. Writing better functions will make your application more stable, easier to read and maintain, and make future development easier.

Django Function-Based Views vs. Class-Based Views

Django views are an essential part of most Django applications. They carry out user requests to perform actions and return different types of data. Django provides two distinct methods for creating a view: function-based and class-based. Many discussions have been had over the benefits of using one over the other. I believe that the benefits of using one or the other is highly circumstantial. In this post, I will outline the guidelines I use to determine which option is better for different circumstances.

Django ORM Optimization Tips

When it comes to optimizing an ORM, your greatest weapon is your understanding of how your ORM works under the hood (at least at a high level). This makes understanding all of the rules and guidelines for creating a speedy application much easier. Therefore, I highly recommend reading through the Django docs on the subject at least once. My goal for this post is to condense these tips and tricks into an easily-referenceable compilation, as well as adding some of my own. Also check out my Django ORM Optimization cheat sheet for an even more condensed version.

Methodic Debugging

Breathe

Shockingly, code that you or someone else wrote has been deemed imperfect and you are now responsible for fixing it. Your first instinct may be to panic. You may have a testy customer or an impatient superior who has made sure to impress upon you the importance of your swiftness. You may just not like fixing bugs. In any case, don’t be so hasty. Rushing a bug fix is a good way to create several more.

Bug fixing is a true test of your problem-solving skills. Bugs are not typically random or due to chance. They each have a logical explanation. If you approach the bug fixing process in an organized and logical manner, you will be able to find solutions in a more reasonable and predictable amount of time.
