In my experience, toasts are one of the worst additions to UX/UI that I've ever seen.

They really are ugly ducklings.

Why does Blazor Hot Reload STILL suck so badly on macOS?

[Matthew Layton @MrMatthewLayton]

I do wish Claude would stop saying "This is weeks-worth of work".

It isn't.

It's hours, if that.

Claude's task for today

Writing a new Virtual Sound Blaster module for NTVDM on Windows XP to fix the horrendous sound in MS-DOS.

Let's see if this works.

If it does, it could unlock a new era of retro gaming!

@otokyo Hiroshima.

[Matthew Layton @MrMatthewLayton]

I might just start building desktop productivity software exclusively for macOS, because Windows is just sucky slopware, and Linux is for servers.

Yeah, I know, horrendously bad take.

Sue me.

Claude > Roslyn Analyzers

Analyzers are dogmatic. You wrote the code, you made decisions, and all they do is moan — no context, no discussion.

With Claude you can ask for analysis, defend your choices, and refactor on your terms.

Not because a linter threw a tantrum.

@hicasamadim Container 3 fills first.

Water flows Tap > 1 > 3 (via lowest outlet).

4, 5, and 6 are blocked.

If container 1's inflow > outflow, then 2 begins to fill, feeding to 7.

7 has a hole in it. If the drain rate exceeds the fill rate, 7 settles at a low equilibrium or stays empty.

@Meech_Ward So they've finally nailed down a non-experimental spec for them?

Well...that took an age and a half. I was a young man when I started looking into JS decorators.

[Matthew Layton @MrMatthewLayton]

@DevLeaderCa I used an abstract class to model Result<T>, Success<T>, and Failure<T>

Why?

because C# doesn't yet support closed hierarchies (coming soon), and this was one place where I needed one.

Result<T> public abstract with internal constructor
Success<T> sealed
Failure<T> sealed

🚨 ONIXLABS DOTNET LIBRARY

In the next version we are adding Int256, UInt256, Int512, UInt512, Float128, and Float256.

We are also adding a complete unit of measurement library, including Area, Distance, Time, Temperature, Angle, Volume, Speed, and many more.

Stay tuned.

@DevLeaderCa Claude Code with Opus 4.7 at the moment, which works really well in conjunction with not only git, but github CLIs.

Also tinkering with GSD, but the last time I tried it, it wafted through way too much ceremony without actually building anything valuable.

[Matthew Layton @MrMatthewLayton]

@LukeParkerDev Most people who hold this opinion do so because of a dislike for Microsoft generally, and/or still think that C# is "Microsoft Java".

C# diverged from Java a long time ago, and is one of the better things to emerge from Microsoft.

@imabig_dreamer @jcouv Classes should be "sealed" by default, following this hierarchy of extensibility:

1. Sealed (nothing can extend)
2. Closed (same assembly can extend)
3. Neither (anyone can extend)

Safety first (sealed or closed). Only leave it open when extension is the expectation.

[Matthew Layton @MrMatthewLayton]

@pauloquicoli @gueldenpfennigr @jcouv sealed = cannot be inherited anywhere
closed = can only be inherited inside the same assembly

[Matthew Layton @MrMatthewLayton]

@mmisztal1980 @jcouv It would be more equivalent to public (and optionally abstract) with an internal constructor — it can only be extended from the current assembly.

@clerk — you guys have one of the best logo designs I've ever seen. So simple, yet so effective.

Claude Code Tip 👨🏼‍💻

The Notification hook with a permission_prompt matcher fires whenever Claude is blocked waiting on you. Pair it with afplay (macOS) and you'll never miss an approval prompt again.

Great for running multiple sessions in parallel.

[Matthew Layton @MrMatthewLayton]

@dinosaurs1969 Funny how many people talk about PEMDAS and still get it wrong.

The answer was right there in front of them. It’s 44.
