priority – How may one reduce the impact of a WSL2 session on the performance of its Windows host?

I have been running some computationally-intensive processes (compiling and linking large programs) in WSL2 on Windows 10 Pro (build 19041.746), and doing so noticably slows down graphical Windows programs, sometimes seeming to halt them altogether for a minute or more.

I have been setting the -j option of the make job that runs these processes to 1, to minimize parallelism, and I am also using ‘nice’ to reduce the priority of these processes within Linux. While this allows me to run other Linux programs concurrently in WSL2, it does not seem to ameliorate the impact on Windows programs (which is to be expected, I suppose, as the Linux scheduler presumably does not ‘know’ about what is happening in its Windows host.)

I went into the Windows Task Manager and found two instances of wsl.exe and three instances of wslhost.exe running (corresponding to one terminal with two tabs open.) I set all their priorities to ‘low’ and restarted the Linux job in one of those terminal tabs, but at best this only slightly improved the situation. Given that the Linux programs do not seem to be slowed down much by what I have done so far, it seems there might be room for the Windows performance to be restored while the Linux programs continue to make progress (I do not care if they are slower, within reason), but is there anything I can do to achieve that?

windows 10 – ShellExecuteEx code 31 error any time I try to launch an EXE

I don’t know if this is the right forum for this question, so please direct me elsewhere if needed.

I am having a new issue launching .exe files. I keep receiving the following error:

ShellExecuteEx failed; code 31.
A device attached to the system is not functioning.

Specifically, I have recently tried to launch the following EXE and get that error:

These are all downloaded from legit sources (Flash remover from Adobe website; R packages from R-CRAN).

I’ve restarted my computer a million times and I don’t have any external hard drives plugged in. When I right-click and Run as Administrator, it still says gives the error box, “A device attached to the system is not functioning.”

Windows 10, ASUS TUF, laptop is about 2 yrs old, issue just started a couple weeks ago (noticed it when I tried to uninstall Flash and just ignored it… now it’s an issue I can’t ignore)

windows 10 – AX200 Bluetooth lost after hibernate / powersafe

Since I changed my M.2 WIFi card on my HB ProBook 440 G5 /w Win10 Pro (the original one was causing random crashes) to an Intel AX200 I have the problem, that when I want to recover from hibernate the PC crashes and I have to hard-reset it by long-pressing the power button. When booting again, neither WiFi nor Bluetooth are working. Re-booting brings back WiFi, but Bluetooth is permanently lost. Bluetooth is not listed in device manager (albeit greyed out when I list unused devices).
When I check the event log, I can find under Microsoft>Kernel-Boot (sorry german):

Fehler: BL_LOG_ERROR_RES_HW_CHANGE: Hardware- oder Firmware-Einstellungen haben sich seit dem Ruhezustand geändert. Status: {Falscher Datenträger}
Die Zieldatei einer Umbenennung befindet sich auf einem anderen Gerät als die Quelle der Umbenennung.

Unfortunately Google is not my friend on that one. Also, I tried a lot of – and combinations of – power management settings, enabling and disabling Windows power management on AX200 in device manager (Bluetooth does not have the setting), setting power management profile for network adapter to high performance, restarting BT services and so on; nothing helped.

The only 2 methods of bringing Bluetooth back were so far: Physically reinstall the original wireless card, booting windows, shuting down again, reinstalling the AX200, rebooting and everything works fine (until next hibernate).
Also, resetting the power management profile was once successful (but is unsafe)

I’m a little out of options. I still see

  • Reinstalling Win10 and hoping for the best (well…)
  • Buy new Laptop (well…..)
  • Migrate to Linux (have still to test if booting linux once brings BT back, but what kind of fix would that be… :D)

I hope you guys have some more ideas. Thanks a lot in advance!

windows – What am I doing wrong to receive Loopback and REST API WordPress Errors?

I’ve taken a dive into self hosting and learning along the way. I have a decent understanding of most of it. It only took me a day to cobble together a “working” NGINX, MySQL, PHP, phpMyAdmin and SSL. I am doing this purely for the educational purposes and fun. A playground if you will. Version information is here. SSL acquired by LetsEncrypt via certbot. The host is Windows Server 2016 Standard 10.0.14393 x64.

I’ve currently ran into a few problems.

  • WordPress Error: The REST API request failed due to an error: cURL error 28: Operation timed out after 10010 milliseconds with 0 bytes received (http_request_failed)
  • WordPress Error: The loopback request to your site failed, this means features relying on them are not currently working as expected: cURL error 28: Operation timed out after 10008 milliseconds with 0 bytes received (http_request_failed)

I have looked through some logs and can’t make heads or tails of it. I have spent a solid day trying random things I have come across. Because WordPress has zero plugins enabled or installed, and only one theme installed and used (default 2020), I am led to believe this is an issue with the server configuration. For reference, here are both the files used by NGINX:

WordPress appears to function fine. But I prefer no errors. I’m not sure where the breakdown is for this. Any help would be greatly appreciated. Thanks.

Algorithm for sorting within windows

I am writing an app which displays speeches on various topics, with each speech having a number of attributes. I want to give the user the choice to sort a list of speeches by an attribute, even within a previously sorted list of speeches – such that, for example, if the previous list had been sorted by speaker and there were three speakers (so the list was split into three windows), and the user was now sorting by length, that the new list would be sorted by speaker, and within each window of speaker, the speeches would be sorted by length (creating a new window within this window for each length of speech in the speaker’s window). I would like to be able to give the user the ability to do this with an arbitrary number of attributes. I start with a flat list of speeches and need to end with a flat list of speeches to display. How can I go about sorting this list within each window, preferably in the most efficient way?

Was There a Release of WMI for Windows NT 4.0 Running on DEC Alpha?

Windows Management Instrumentation (WMI) was made available as a separate download for Windows NT 4.0 SP4 and above. I know that WMI installs and works great on Intel IA32 (x86) flavors of NT4, because I have the WMI redistributable and I’ve tested it.

However, Windows NT 4.0 Service Pack 4 (SP4), SP5, SP6, and SP6a were released for both the Intel IA32 (x86) and DEC Alpha architectures of Windows NT 4.

My question is: did Microsoft release a WMI redistributable for NT4 that worked on DEC Alpha?

I have a WMI redistributable for NT4 (wmint4.exe, SHA256: A958C28D19507784BC66D42404952D755281FF3549660605613C4EDD3E489809), but I do not have a DEC Alpha system to know if it would install there. I could also speculate that there may have been a separate download for DEC Alpha NT4 systems.

For completion sake, it is worth noting that Windows NT 4 was originally released for MIPS and PowerPC platforms, too, but Microsoft abandoned further development for these platforms before the release of SP4. Because the WMI redistributable required SP4, I can conclude that WMI could not be added to MIPS or PowerPC versions of NT4.

linux – I’ve created a bootable Windows 10 USB Drive, but my desktop will not load it

I followed a tutorial online to create a bootable Windows 10 USB drive on Linux, but it does not boot when I choose it from the boot menu. I’ve been waiting for a while, hoping it just had to load, but it’s been almost 20 minutes, and basically nothing is happening. I am using a desktop pc, and the BIOS is “MSI CLICK BIOS 5” (not sure if that matters). Also, would it change anything if it’s plugged into a USB 3.0 instead of a USB 2.0 slot?
