You may have stumbled on the Either type at some point if you used a functional programming language. Or perhaps the Result type in Rust. Their purpose it to explicitly embed the possibility of failure into a signature, while also treating errors as values (rather than raising exceptions). Union types
This post is aimed at people who are (forced to) using Python and are interested in Functional Programming and Static Typing benefits, that allow you to detect many potential errors at dev-time and prevent costly follow-up errors. First, I will give a quick recap about basic static typing (using mypy)
I recently started working with Kotlin. And unlike in my Rust and Scala projects, Github did not suggest a CI workflow for me. You can use a bog-standard Java workflow and just add two commands: chmod +x gradlew ./gradlew test --no-daemon Here is the workflow (goes into .github/workflows/ci.
I will start this article by demonstrating the problem that I was facing. I am developing a game in Ratatui, a really nice library for creating UIs in the terminal (TUI). Ratatui offers a builder pattern for widgets. Step 1: Building a simple widget // area: Rect, buf: &mut Buffer
Intro: Simple enums and exhaustiveness checking in PHPStan If you use enums (enum = enumeration of all possible states) then you can perform exhaustiveness checking. Before we proceed to Rust and Java, I am using PHP with PHPStan to give a quick introduction to the concepts at hand. enum GraphicsPreset { case
Native image generation by GPT-4o has hit the market. This means, the LLM no longer delegates image generation to Dall-E via prompts, it is now able to produce images on it's own, translating from text to images internally. The most notable immediate upgrade is the ability to create
I find myself needing to work with .webp files a lot recently. The default file browser (Nautilus) in Ubuntu 22.04 does not have previews. Enable webp previews To change that you can install webp-pixbuf-loader. As always, adding a 3rd party repo is risky, so think about whether you want
I've recently seen a "developers as RPG classes" post on LinkedIn; I don't remember what it was, just that it was disappointing. So I decided to make my own. 🛡️ Paladin: Carries the holy book of functional programming and wields the refactoring hammer. 🔮 Sorcerer: macro-level
When writing PHPUnit tests for your Http clients in Laravel, you probably know about Http::fake() and Http::assertSent(). Here is an example of this: use Illuminate\Http\Client\Request; Http::fake([ 'hehe' => Http::response('hehehe'), 'hihi' => Http::response('hihihi'
In a previous article I explained how Scala allows seamless function chaining via extension methods and pipe(), and then went on to replicate something """kind of""" similar in PHP: Creating a type-safe pipe() in PHPI am an absolute fan of pipeline-oriented programming. In this
Install the dependency: composer require --dev larastan/larastan If you are using Laravel, make sure to install larastan. Laravel comes with a huge amount of magic that is not compatible with a static type system, but the larastan package covers most of that. It installs phpstan under the hood and
In this article, I want to provide a holistic view about generative AI models and applications. I want to give an abstract notion of what LLMs are, some technical details about how applications like ChatGPT can infuse them with additional capabilities, how developers cope with the technical limitations and what
