  • The common sketchy performance advice is to disable mitigations in the kernel, this post is about disabling mitigations in Intel’s userspace graphics stack because it’s already checked in the kernel.

    Assuming you meant disabling kernel mitigations, since AFAIK audio stuff doesn’t usually use OpenCL:

    Has anyone else here disabled it?

    Nah, my understanding is it’s not worth it on newer CPUs, and in some cases, the microcode expects things to be mitigated for best performance. Older CPUs (pre-2019ish) it does make a difference though.

    But you’re welcome to benchmark it, and see if it makes a worthwhile difference on your CPU. Kernel mitigations are easy enough to turn on and off.

    My understanding is previously the kernel would crash on systems with more RAM than the address space, so there’s now a patch to ignore the anything above the max address supported (e.g. 32bit without PAE, 36bit with PAE). More RAM was never supported, so I think the author of the article has misunderstood or oversimplified what’s been done.






  • I got through University running Debian testing. It was mostly fine, some Linux based subjects were way easier without dealing with a VM (they recommended against WSL for some reason).

    However there were a couple units that absolutely required you to use Visual Studio (non-code), I occasionally used a VM, the Uni IT also provided me with a remote VM (there’s a form to fill and and it’s all automated). But I mostly used Rider, which for one unit it confused their CI and I got marked down for (otherwise got top marks so it’s fine).

    For office, it didn’t matter. Group projects mostly used Google Docs, occasionally Microsoft Office where the online version worked fine. All my units wanted PDFs at the end anyway, so it does not matter that you used LibreOffice or whatever. Some units provided you with DOCX templates, I had no issues opening them with LibreOffice.

    Edit: People are mentioning online exams, my Uni did ‘online quizzes’ which worked fine, and some had to be done in class on their PCs anyway. Final exams where always done on paper.


  • Ahh sorry, I thought you meant you plugged it into the input side. If that’s the case then are you running anything that measures CPU usage? I run the TIG stack, it might be able to give you some hits. Also back to my original point which is already unlikely, if it’s a modified sinewave UPS, it can confuse some measuring devices while it’s on battery.








  • I never mentioned vulnerabilities, I just wanted to point out that, RDP doesn’t really work without a graphical session, Windows Server Core gets around this by being a graphical session (although very basic).

    Also I’m not sure, but I don’t think Windows handles RDP on the kernel level, it’s just nicely tied in with DWM and doesn’t have to deal with the multitude of window managers on Linux.

    Handling RDP on the kernel level does sound like a bad idea security wise, but there should be a better way.
