I've seen some begginer programmers asking themselves: why do I even need constants? Variables I get, they're super important, but why have an extra thing that's like a variable, but worse? It can't even change! And if I know that const NUMBER_OF_COLUMNS = 3, why can't I just write 3?
The PHP ecosystem is full of frameworks: Symfony, Laravel, Yii, Zend, Phalcon, and so many, many, many more... All of them built by professionals and supported by big communities. So why on earth would a junior developer, who has just started his first job, try his hand in building yet another one?
I had to learn Git as a programmer. If you want to easily collaborate on a codebase, you really need either Git or something similar. But as a non-programmer, you’ve probably never even heard that name, have you? Then why would you ever need it?
A Coding Dojo is a great way to practise programming, test-driven development, teamwork, pair programming and problem solving. Avris Dojo provides an easy way to synchronise your dojo codebase with your teammates.
Keeping your classes immutable and stateless makes your code way less prone to bugs. Yet somehow this clean code rule isn’t as popular and as often invoked as SRP, YAGNI, DRY, KISS and others... Maybe it’s because of the lack of a catchy acronym?
Anyways, I’d like to take a look at two examples of when sticking to this rule could save your ass (or at least save you some time debugging).
Having 100% of LOC covered by unit tests certainly feels like a great achievement. But beware – that doesn’t necessarily mean your code is perfectly covered. Lines of code coverage is a really nice indicator of your app’s stability, but is can also hide some risks.
Programming isn’t that hard. Really. With enough time and determination, almost everybody could write some useful code. The Internet is full of tutorials that teach you programming from scratch, full of people who faced the same problems you do, full of people who solved those problems and shared their solutions for you to use, and finally full of free libraries that you can just use. All you need to do is learn some tools, google your problems and put together pieces of code that you find.
But if it’s not a black magic, not a secret knowledge, then why are software developers so well paid?
Finally. I got to work and rewrote the code of my sweet blog. Brand new design, new framework, Micrus, better support for language versions, a couple of new features in the admin panel, ditching custom comments for the awesomeness of Disqus, ditching TinyMCE for the beauty and simplicity of Markdown. It was a lot of work, but it was definitely worth it!
Wreszcie. Wziąłem się do roboty i przepisałem od zera kod mojego blogaska. Zupełnie nowy design, nowy framework, Micrus, lepsze wsparcie dla wersji językowych, parę nowych ficzerów w panelu administracyjnym, rzucenie własnego systemu komentarzy na rzecz zajebistości Disqusa, rzucenie TinyMCE dla piękna i prostoty Markdownu. Zajęło to sporo pracy, ale zdecydowanie było warto!
Code golf is a type of recreational computer programming competition in which participants strive to achieve the shortest possible source code that implements a certain algorithm. [source]
Picco is a tiny PHP web framework that only takes ~2,5 kB of space and has no dependencies on other libraries, while still providing quite a lot of features, being extensible and reasonably easy to use.
The idea is to create a simple (in terms of complexity, not ease of use) programming language, that will have quite a concisesyntax, that will play with the power of Unicode and most importantly – will be fun to create ;)
