it's easier to remember that it originated from the Byte range, where all bytes could be kept in. Character didn't have negative values so it did [0-128) instead. Long and Short are the same as Byte.

Years before the autoboxing/Integer.valueOf() caching stuff (and before generics), (I) used to have IntegerProvider that did similar stuff to higher ranges. Personally, I have considered autoboxing on integers net-negative for Java

>S4 suspend

Is not popular in general, so yes. But also no - I don't use swap ever, if I have to go over the RAM (32GB being low, with 64GB the norm), might as well consider the system dead.

bytecode manipulation has been a thing ever since late 90s and early 2000s (e.g. BCEL, Jan, 2001), along with byte code decompilation.

Generally one must understand how bytecode signatures, all flavors of invoke, and constant pool work. After that using visor pattern or 'functional' alike stuff makes no difference whatsoever.

I have used (still using) bytecode manipulation along with custom classloaders as part of my job (albeit not on daily basis any longer). Personally, I don't consider objectweb asm hard to use in any way. and java's class file won't be funnier - perhaps it was the very project I'd not pick bcel, though.

>It feels like Pascal in Cyrillic

replace cyrillic w/ russian and it'd be ok.

КНЦ = end (конец in russian is end). However, in bulgarian in means 'thread' (as in sewing thread) and it has lots its meaning of end, aside from 'from needle to thread' expression where it means from the tip of the needle to the end of the thread.

Also 'ALL' (и все = it's over/that's all), which should be 'end' as in begin/end in pascal.

The main point still stands - it's Pascal.

I can do "ctrl + +" to increase the font, but it's still serif and low contrast, so I have to do "ctrl + A". Or better yet - press "reader view" on firefox.

of course, it's hot-swap material, the microcode is 1st deployed by the bios, then the OS can apply changes as well.

Just that it's writable by $ (not #) feels awkward.

Even though you're commenting on While Rabbit post, it took some time to understand "WR" is white rabbit, esp. since describing the pico seconds in brackets.

Posting comments in bad faith is not funny, e.g. EU permanent residency requires 5 (or 7) years to have been resident already.

> has the ability to LEARN so much faster with an AI research assistant, and that becoming an expert has accelerated for those with the personal stamina to dig deep (this as a requirement hasn't changed)

If anything it allows to be as lazy as possible. I have not seen anyone digging deeper with the AI tools.

>I wonder if other languages are less ambiguous about this.

most are (few others I can speak). Generally, passive voice and past tense do not collide by having the exact same suffix. The fact the headline lacks a verb (when interpret correctly) doesn't help either.

New comment by xxs in "A nicer voltmeter clock"

xxs — Mon, 18 May 2026 06:50:04 +0000

PWM is used in pretty much everything.

Any power supply, any voltage regulation (A cpu has multiple voltages, e.g. core, SoC, cache,), most LED brightness control, lots of motor speed controls and so on.

Like mentioned transistor (esp FETs) like to be fully open or fully closed. Class-D amplifier requires to convert the naturally analog signal, unlike say a power supply that has a voltage ref. on/off, with sampling 1st. It makes it for a relatively poor example of PWM use.
