That sounds quite troublesome if the encryption key is lost, compromised, or rotated for any other reason.

That looks cool!

I agree with your point, but I must correct you on DOS: it had device drivers too. :) That's how we used to access mouse input, CD drives, network, extended memory, etc. Yes, it sucked on the graphics and sound; every app basically had

Or you could target .NET Framework 4.8 which is supported by all Windows OSes out of the box albeit quite outdated.

Microkernel architecture doesn't magically eliminate bugs, it just replaces a subset of kernel panics with app crashes. Bugs will be there, they will keep impacting users, they will need to be fixed. Rust would still help to eliminate

> But that's easy to fix, so just implementation quirk for this particular library, the idea is sound. It's in ULID spec.

UUIDv7 is the closest to ULID as both are timestamp based, and UUIDv7 has fewer quirks than ULID, no question about it. I agree that picking UUID variant requires caution, but when someone has already picked ULID, UUIDv7 is easily a superio

To implement a thread-safe sequential increment, you need locking. When you use locking, then it becomes a “non-universal” ID generator with arbitrary performance impact. Either it’s collision-prone or locking. Both are problematic in their

Thanks for the heads up, then it’s one less reason for ULID to adopt this weird behavior.

Yes, the problem is that this mode is supported and required per the spec. So, a developer must know the pros/cons of this mode. It requires them to correctly assess the consequences. It's quite easy to shoot themsleves in the foo

You mean someone who wants to attack your system might be discouraged by Base32 encoding?

Not if the same ULID generator instance is used across threads.

> You only need to lock sequence if you care about IDs being ordered within a millisecond Yes, and that's when sequences are only used. I guess that's to avoid hogging the CPU or emptying the OS entropy pool during high loads.

You're right, not hosts or processes in that case. I forgot about random part as it's been a while since I looked at it. However, a single instance of a ULID generator must support this mode, which means that on multi-threaded arc

Whenever ULID comes up, I need to remind that it has a sequential ID generation mode in its spec which is prone to conflicts on multi-threads, processes or hosts which kills the purpose of a "universal" identifier. If you need a s

Yeah it went on about 12 hours which might be a record. But this was the 38th eruption this year. Others may not have been as big as this though. That said, it feels like a once in a lifetime experience, yes. See my video: https:/&#x2

Yes we watched it in the night too. It was disappointing to see iPhone “normalizing” its brightness down. I had to take raw photos to capture it.

I was there today. We happened to notice the smoke over Kilauea while driving to Hilo, then checked out USGS cams, and immediately drove there and spent the next 7 hours getting mesmerized. As my first eruption encounter, I didn’t expect t

It’s a very trimmed down kernel with minimal set of drivers and modules. It doesn’t even support SD cards out of the box. That’s probably the main reason as no hardware probing/initialization delays are incurred.

Those GUIDs aren't related to NT kernel but Windows Explorer and its COM-based component system. They were introduced with Windows 95, IIRC.
