Counter Strike: Source won’t start on NixOS

After the latest update of my NixOS machine, Counter Strike: Source wont start. Starting Steam from console shows the following error message

src/] Attempt to free invalid pointer 0x94d1af0 
/home/user/.local/share/Steam/steamapps/common/Counter-Strike Source/ line 73: 14550 Aborted                 (core dumped) ${GAME_DEBUGGER} "${GAMEROOT}"/${GAMEEXE} "$@

I could fixed the problem by

  • copy the from Half-Life 2 bin-folder (/home/user/.local/share/Steam/steamapps/common/Half-Life 2/bin/ to Conter-Strike: Source bin-folder
  • Rename existing to or similar
  • rename to

The game now starts 🙂

Logging from PHP to Docker logs (stdout)

If you run your PHP application inside a docker container, you could write (debug) output to the docker log. This is useful if you want to see the output of your application in the docker logs.


$out = fopen('php://stdout', 'w'); //output handler
fputs($out, "Output goes here...."); //writing output operation
fclose($out); //closing handler


function _log($msg) {
    $msg = "myApp - " . date("c") . ": " . $msg."\n";
    $out = fopen('php://stdout', 'w');
    fputs($out, $msg);

Fixing Windows Hello PIN on Windows 11 (0x80090016)

This is the second time, my Lenovo X13s (Windows-on-ARM) machine wont boot and ask for the BitLocker key. After using the recovery key, and login with password, i can't set a new Windows PIN which is needed for biometric (fingerprint or face recognition) login. I get the error message Something went wrong. Try again later (0x80090016).


To fix this, you need to delete the folder C:\Windows\ServiceProfiles\LocalService\AppData\Local\Microsoft\NGC and reboot the system. After that, i was able to set a new PIN.


  1. takeown /f C:\Windows\ServiceProfiles\LocalService\AppData\Local\Microsoft\NGC /r /d y
  2. icacls C:\Windows\ServiceProfiles\LocalService\AppData\Local\Microsoft\NGC /grant administrators:F /t
  3. Delete C:\Windows\ServiceProfiles\LocalService\AppData\Local\Microsoft\NGC
  4. Reboot
