Ok, lots of Russian trolls out and about. It's entirely clear why the change was done, it's not getting reverted, and using multiple random anonymous accounts to try to "grass root" it by Russian troll factories isn't going to change anything. And FYI for the actual innocent bystanders who aren't troll farm accounts - the "various compliance requirements" are not just a US thing. If you haven't heard of Russian sanctions yet, you should try to read the news some day. And by "news", I don't mean Russian state-sponsored spam. As to sending me a revert patch - please use whatever mush you call brains. I'm Finnish. Did you think I'd be supporting Russian aggression? Apparently it's not just lack of real news, it's lack of history knowledge too. Linus

www.infoq.com Java 24 to Reduce Object Header Size and Save Memory
JEP 450 (Compact Object Headers) has been targeted for delivery in JDK 24. This currently experimental feature optimizes heap utilization by shrinking the size of the mandatory object header in HotSpot. This should reduce overall heap size, improve density of deployments, and increase data locality.

I have an apostrophe and it’s super annoying as some companies see it as a SQL injection hack and sanitize it.
My surname contains a character that's only present in the Polish alphabet. Writing my full name as is broke lots of systems, encoding, printed paperwork and even British naturalisation application on Home Office website. My surname was part of my username back at uni, and everytime I tried to login on Windows, it would crash underlying LDAP server, logging everyone in the classroom out and forcing ICT to restart the server.

chrisdown.name In defence of swap: common misconceptions
tl;dr: Having swap is a reasonably important part of a well functioning system. Without it, sane memory management becomes harder to achieve.
To be clear, I don't blame the poster of this comment at all for the content of their post – this is accepted as "common knowledge" by a lot of Linux sysadmins and is probably one of the most likely things that you will hear from one if you ask them to talk about swap. It is unfortunately also, however, a misunderstanding of the purpose and use of swap, especially on modern systems.
I'm not sure if you understand what swap actually is, because even machines with 1Tb of RAM have swap partitions, just in case read this post from a developer working on swap module in Linux https://chrisdown.name/2018/01/02/in-defence-of-swap.html

davidvlijmincx.com Virtual vs Platform Threads When blocking operations return too fast
In this post, I look at Virtual Threads and if they are a silver bullet for blocking tasks.
The Linux kernel uses the CPU default scheduler, CFS,
Linux 6.6 (which recently landed on Debian) changed the scheduled to EEVDF, which is pretty widely criticized for poor tuning. 100% busy which means the scheduler is doing good job. If the CPU was idle and compilation was slow, than we would look into task scheduling and scheduling of blocking operations.
EDIT: Tried nice -n +19, still lags my other programs.
yea, this is wrong way of doing things. You should have better results with CPU-pinning. Increasing priority for YOUR threads that interact all the time with disk io, memory caches and display IO is the wrong end of the stick. You still need to display compilation progress, warnings, access IO.
There's no way of knowing why your system is so slow without profiling it first. Taking any advice from here or elsewhere without telling us first what your machine is doing is missing the point. You need to find out what the problem is and report it at the source.
The CPU is already 100% busy, so changing number of compilation jobs won't help, CPU can't go faster than 100%.

It's a regression, so ffmpeg should fix a regression.
It really depends on where you set the limit on what ORM is, JOOQ is kind of a thing you're looking for.
