kvemkon··on C++ Insights – See your source code with the eyes of a Compiler
> See your source code ...

What I'd like to see, is how much time is spent to compile each block of C++ code (sliced as fine as possible).

kvemkon··on Memory Companies Have Destroyed the Consumer Market
All(?) ASUS mainboards got a week ago a new BIOS:

> Enhanced memory performance, system stability, and compatibility with CXMT memory chips for improved low-latency operation.

A year ago I'd hardly know what CXMT is.

The famous TI C55x DSP with 16 bits byte for example: https://news.ycombinator.com/item?id=3112704.

And they are still available new for purchase.

kvemkon··on How I changed teaching after AI managed to do all my homework assignments
> and you have to actually grade the exam

That's the point. As a professor you're allowed to outsource the grading of written exams to you assistants (ongoing PhD teaching stuff). But you must do an oral exam personally.

> usually quicker for the well prepared students

That's true. More time is needed only in case the answer is missing and you have to check whether you hit accidentally the only poorly understood material piece or there are more troubles.

Well, since the name is a "variable", it must by default be mutable. Otherwise it is an exception being forced to become a standard case.

kvemkon··on Audacity 4.0
> since computers are getting new hardware features

It's not possible to move forwards fast anywhere.

> and removing features

Yeah, this is indeed very unfortunate. They claim the GTK core team is about 2 devs, so tiny that we're lucky the development goes further at all. Hard to understand considering Red Hat became part of IBM.

1.6 MW power [1]. Would be 2 minutes for take-off realistic?

kvemkon··on Audacity 4.0
> so difficult to upgrade to new versions

Perhaps, because GTK developers insist, that GTK2, GTK3, GTK4 are different toolkits.

> Qt4 to Qt5 usually only involved ...

I'd start with Qt3 to Qt4.

kvemkon··on Audacity 4.0
I can still use and develop GTK2 software in Debian out-of-the-box, but not Qt3 or even Qt4.
kvemkon··on Show HN: I missed the moving blocks, so I built a real Linux disk defragmenter
> to a newly-allocated part of the drive's LBA space

Which is rather a case for home use, not practical for highly parallel access industrial use cases. That's why the issue became a research topic. For the first time I saw a proof that the "fact" SSDs do not need defragmentation is actually a myth. Well, you still want to avoid explicit defragmentation (waste of time and SSD lifetime) by filesystem driver submitting additional hints (using new NVMe extensions) to the SSD controller about what blocks belong to the same file, so that SSD can place them for an optimal sequential access with properly interleaving (not necessary strictly physically consecutively whatever this means on SSD).

To visually inspect fragmentation of a partition on Linux, a tool exists since 15 years: https://github.com/i-rinat/fragview. Just in case.
kvemkon··on Tether: iMessage, SMS, etc. on Linux
That's what I thought at first but then discovered:

> universal clipboard is synchronized over internet, it is not done trough cable connection. it uses apple continuity service, what you put into UC is uploaded into apple cloud,..

https://github.com/libimobiledevice/libimobiledevice/issues/...

That's why I'm a bit confused now.

> don't let the "KDE" fool you

Being GNOME2-then-MATE user, it really would.

kvemkon··on Tether: iMessage, SMS, etc. on Linux
Is there an easy way to share iOS clipboard to Linux directly using local WiFi without going through any cloud?

This is an interesting point of view. I've been thinking that only the moment counts, when the manufacturer has been made aware, regardless when the manufacturer has in fact actively become aware. Thanks!

kvemkon··on How Europe is killing makers and micro-entrepreneurs
If the law wouldn't say 24 hours counting only working hours (3 working days for small business or even weeks during vacations), then it wouldn't be an exempt.

Well, how small business can report anything during 24 hours through weekends, long weekends, 1-week Christmas, 3-4-weeks summer vacations?
