In this chapter, we learn about tools for only running a piece of code if a condition is met: truth values (booleans), comparisons and if statements.

I’ve been on the lookout for a scripting language which can be neatly embedded into Hare programs. Perhaps the obvious candidate is Lua – but I’m not particularly enthusiastic about it. When I was evaluating the landscape of tools which are “like Lua, but not Lua”, I found an interesting contender: ...

An introduction to the new Results Table integrated into the output cell of Notebooks, powered by the VS Code extension called Data Wrangler. The post Announcing the Data Wrangler powered Notebook Results Table appeared first on Microsoft for Python Developers Blog.

Firefox is now the first and the only browser to deploy fast and comprehensive certificate revocation checking that does not reveal your browsing activity to anyone (not even to Mozilla). Tens of millions of TLS server certificates are issued each day to secure communications between browsers and we...

Quick question: How many numbers are there from 5 to 18, including both ends? Your first instinct might be to subtract: 18 - 5 = 13 Feels right. But it’s wrong. It’s a small thing, and kind of basic, but this mistake got me more times than I’d like to admit. Eventually I learned how to count ranges ...

Let's be honest: Half the APIs you write are for a specific purpose in a specific component on a specific page. Re-usable in theory but you've never tried. That's where Server Components come in ... but what if your server isn't JavaScript?

I do not consider myself an expert in generative AI, but I now know enough to build full-stack web applications on top of generative AI models, evaluate the quality of those applications, and decide whether new models or frameworks will be useful. These are the resources that I personally used for g...

In Neon, we’re always trying to strike a balance between out-of-the-box configurations that work for most people and the flexibility to accommodate a wide range of use cases. By tweaking features like autoscaling, branching, and scale to zero, you can optimize Neon for many different scenarios – fro...

How to make your customers happy and your engineers even happierIt’s common for monitoring and alerting solutions on production services to be quite chatty, sometimes producing hundreds of notifications per day. There’s a scene in the classic film The Matrix where one of the characters (Cypher) is l...

Discord and NVIDIA partner to showcase cloud-streamed gaming experiences on Discord to transform game discovery for players and developers, starting with Fortnite.

In this chapter we look at one way of storing more than one value in a variable: arrays.

Trust calibration is a concept from the world of human-machine interaction design, one that is super relevant to AI software builders. Trust calibration is the practice of aligning the level of trust that users have in our products with its actual capabilities. If we build things that our users trus...

Build a professional deployment workflow for your Supabase project. Learn essential patterns that prevent 3am panic attacks while keeping your workflow fun, simple, and safe.

A few of the ideas, topics, and commonplaces that have been gaining steam on <a...

In the last chapter, we worked with numbers. In this chapter, we’ll work with text and write our first applications.

Type annotations are a workaround for compiler limitations, not a feature—a well-designed language should infer all types automatically, forcing programmers to write smaller, cleaner modules.

Master the art of communicating with AI coding assistants through effective prompting strategies, iterative refinement, and systematic approaches that turn ideas into deployable applications.

Get your AI-generated app ready for production with this comprehensive guide covering security, performance, and deployment best practices.

Build a testing strategy that prevents production disasters without turning development into a slog. Learn which tests matter, which tools to use, and how to catch bugs before your users do.

In the Stack Overflow 2025 Developer Survey, “84% of respondents are using or planning to use AI tools in their development process.” They don’t break this number down by developer language, but if they did, they would likely find a wide disparity between different languages. While TS/JS and Python ...

This is an interactive article. To fully experience it, you'll need to turn JavaScript on. I recently made the Space Invader Generator for Creative Coding Amsterdam code challenge. I made it for fun of course... and galactic domination too! You can see how it looks below and in this post I'll show y...
