Twitter's domain is now officially x.com — this is probably the worst rebranding I've ever seen 😄

Async/await in #TypeScript is essentially “direct style”. It will be interesting to see if Effect, a monadic effect system, will take off, as a case study for #Kotlin & #Scala — although for “direct style”, these have the advantage of context parameters.

Anecdotally (n=2), trying to teach teenagers programming by allowing them to use GitHub Copilot / ChatGPT hasn't been going well. Copilot/ChatGPT will generate code that they don't understand, sometimes with mistakes. And I noticed no progression happening while it's used.

On the need for debuggers … I use it rarely because of FP, unit testing and println().

OTOH, I think we are deluding ourselves. We don't do debugging b/c the tools suck. Nothing ever comes close to having a real console at your breakpoint:

import pdb; pdb.set_trace() #Python

I'm starting to assess the health & maturity of programming languages by the availability of
‣ good LSP implementation (VS Code, vim, etc.);
‣ good IntelliJ IDEA plugin.

None is optional, I want both.

#FunctionalProgramming will make you build better software, regardless of language. Some understated effects:
‣ Prefer params to global state
‣ Prefer data pipelines to fragile state mutation
‣ Prefer clear responsibilities for components
‣ Make dangerous side effects visible.

The series of articles titled “My Scala Story” is pretty cool, worth a read 🥰
Interesting to see how many came to #Scala for mostly the same reasons — having fun with #FP 💪👾

#Preact, the light alternative to #React, doesn't require a build process, as it's using:

‣ tagged templates, instead of JSX;
‣ JavaScript modules.

This is the future of #JavaScript:

PRO-TIP: #ScalaCLI can compile packages with #GraalVM's native-image. And without --no-fallback, the compatibility issues (e.g., w/ reflection) are minimal.

Fast startup, reasonable binary size, good RAM use 💪

"Update NextDNS with a Scala CLI script"

Today I was reminded how awesome Scala is for scripting, via Scala CLI. And it goes beyond having “batteries included”.

#Firefox for #Android opened access to more extensions. I use uBlock Origin and Dark Reader.

Other reasons to use Firefox on Android — history sync that actually works, “open in app”, multiple search engines, not adversarial, feels good using it.

In principle, I know the advantages of dynamic type systems — treating code as data, or inventing types on the fly, based on runtime conditions. In practice, I've never seen any good use of dynamic type systems, only downsides.

Everything good about dynamic type systems has to do with tooling. The culture of simplicity, the REPL, the scripting, creating types based on external input (DBs, JSON files), etc. These are all great, yet nothing that a static language can't do better.
