Thanks for the correction. Your project is very interesting. I think that my mistake was caused by this, that some manual I read in old days was claiming that m68010 was the first one which was able to run proper unix OSes, because it had c

For historical record, first m68k which could use mmu was m68010 I've never seen m68008 m68010 and m68012 in action though. Seems Sun used them.

Well.. I just noticed that implementation of inet_ntoa in glibc is a bit suspect. Using %d with char, without typecasting to (int) or using %hhd is tricky, and depending on memory alignment rules, and on whether arguments are passed in regi

I'm speculating heavily here, but it seems TLS seems to be userland thing, but with OS support (e.g. CLONE_SETTLS flags, *_thread_area()). Maybe it was thought more like a thread-level thing, and not runtime thing. E.g. if we had some

If someone wants to buy additional 10G card, and has ~300 USD to spare I suggest Intel E810 series. The cheapest E810 version is, I believe, E810-XXVDA2 which has 2x28Gb SFP ports (so good for the future), and uses PCIE4, which makes it wor

by jagrsw 5y ago
They're 50USD or so. The main problem seems to be that they use ~3-4W of power each, and it's more than power budget of a single SFP/+ slot (2W or so), and they become v.hot (~70°C), what can lead to overheating of switches.

Thanks all in the thread for explanations. I had matrix multiplication at the Uni (IT faculty, many years ago) as part of algebra courses, I memorized, I passed the exam, and forgot the topic. Though, I don't remember anyone explaining

I understand the rotation part and some uses, but what's the intuitive explanation for why it's done this way? Convention? IOW, what matrix multiplication tries to achieve by doing this manipulation which looks like rotation visua

Having two monitors with different DPI or physical size. Wayland supports different scaling per monitor, so your windows will look thesameish in terms of physical or pixel size (depending on your wishes) when moving them across monitors :).
