I'll be talking about Tailwind vs. CSS at the FrontKon conference in a couple of weeks. Controversy or harmony? 👀

Counting rows on an unusual chessboard seems simple since you sense there's a trick. But I couldn't get any major LLM to answer correctly without big hints. Do you have similar examples?

One of the reasons I like using Gemini 2.5 Pro for tech specs is that it can defend its decisions. If I ask, "why didn't you X?" it will give me the rationale and let me debate back and forth. Compare that to Claude: "You're absolutely right! I should have done X." Much less helpful.

The Temporal proposal provides a replacement for Date, a long standing pain-point in the JavaScript language. This blog post describes some of the history and motivation behind the proposal. The…

What is all the rage about parallel AI agents? And how is it great to let the agent work for hours?
I get that it solves the current problems, but overall it feels wierd.
Why? Because humans can't really think in parallel. 1/2

Question: Why did you build a cli tool instead of an IDE?
Boris from Anthropic: There is good change that by the end of the year people aren't using IDEs anymore.

I stay well clear of enums.
in fact as soon as ts 5.8 lands (with this PR: github.com/microsoft/T...) I'll be enabling `--erasableSyntaxOnly`
I've started using `--experimental-strip-types` in node too.
I use typescript for checking + intellisense, not in my build pipeline

Today TypeScript 5.8 Beta ships the new "erasableSyntaxOnly" flag 🎉
It is designed to pair with Node's built-in TypeScript support, guiding users away from TS-only runtime features such as:
❌ enum
❌ runtime namespace
❌ parameter properties
Remember: TS = JS + Types 👍

TypeScript 5.8 Beta is released 🎉
🔶 "nodenext" gets require(ESM)
🔶 "nodenext" deprecates Import Assertions
🔷 Checked Conditional Return Types
🔷 erasableSyntaxOnly flag for Node
🔷 Perf: libReplacement flag
🔷 Perf: Program load/update optimizations

We just released the beta for TypeScript 5.8! This release brings support for Node.js' require(ESM), smarter/safer checks for functions using advanced types, a few great optimizations for editor scenarios, and more. Give it a try!

I was casually driving home, not really concentrating on what 'someone' was talking about. Suddenly I heard my name! It took me a while to realise that I was listening to none other than Eric Meyer in his Igalia Chats podcast. What an unexpected situation.

I progressively love VueJS 😉 . It was ok in version 2 with Options API, but now on version 3.5 with full Typescript support, Composition API, and latest syntax features it is great.
