• Interesting Whisper AI CPU vs GPU Test


    This is not scientific but Itook an old Xeon V4 workstation and an old Quadro GPU and compared the Whisper times for the same approximately 4 minute audio, transcribing in English. Here are the times which is slightly surpising. I used the small model with this command: whisper vid.mp4 --model small --output_format srt --language en Of course to test the GPU I added the --device cuda flag and confirmed GPU was being use........
  • QEMU KVM Keyboard Problems Not Working Right Repeating Characters, Ctrl+C Copy and Paste not working right when using PS2 mouse in guests Solution


    It seems that QEMU/KVM's default PS2 mouse and keyboard doesn't work right in most cases. I have especially observed issues using Ctrl+C and Ctrl+V and in Linux you may see repeated key presses in the terminal and you will wonder why you copied something and it's not in the clipboard when you try to paste. The way to temporarily fix it is to press the key that is repeating once(works in Linux but not really in Windows). Sometimes when moving your mouse it will also s........
  • How To Speed Up Linux Ubuntu and Debian Based Computers By Improving CPU Performance and Changing the CPU Governor


    I used to believe that for Desktops especially that the "ondemand" CPUfrequency changing that kernels included with Ubuntu and Debian based distros have would be sufficient for snappy performance. However, you can feel the lack of performance on the fastest computer if you have ondemand. A lot of times even under high load 100% of your CPUfrequency in MHz will not be used. For example a 2.8Ghz CPUmay only run at 1.8MHz or even .9GHz. Now........
  • exim high load and dozens of processes


    This server was experiencing loads of up to 80 and maxing out the RAM and kmemsize on a CPanel VPS. There were literally dozens if not hundreds of exim processes. I have no idea why exim has such a design that would allow it to consume this much CPU and RAM. Any normal MTA should not be spawning so many processes, it should be processing them in sequence and if it is going to spawn hundreds of processes in response to a large volume of mail, it's better to have a delayed del........
  • Unlocked iPhone 3GS and firwmare 3.0 battery short low life horrible


    This is pretty bad, ever since my phone has been unlocked the battery life is horrible. Many others have reported this issue on provider unlocked phones and even jail broken phones. We're talking issues as bad as losing 1% every 3 minutes which is what I seem to have observed as well. For now I'm going to relock the phone, and hopefully a firmware update will address this issue. This is very annoying and it seems apparent this is also happening on 3G phones and that........
