• Linux and Windows Dual Boot Issue NIC Won't work After Booting Windows


    In Windows, with some NICs, especially Intel, Windows may enable features on the card that break it in Linux. It is hard to troubleshoot as what you'll see is that the NIC is still detected in Linux, the NIC/port will be up but nothing will work (eg. DHCP requests or even static IPs won't work). You may see STP bridge traffic but that is all. In a corporate environment this can result in many calls to support and is essentially downtime and an unnecessary waste of resource........
  • Nvidia Tesla GPUs K40/K80/M40/P40/P100/V100 at home/desktop hacking, cooling, powering, cable solutions Tutorial AIO Solutions


    Do you have access to some old Tesla GPUs and want to try them at home in your Desktop or old Server? Some people have wanted to try these units for gaming but keep in mind they have no video out port, they were only meant for AI applications such as Deep Learning. The easiest way by far is to choose an AIservice that has everything ready to go, perhaps with a bunch of Docker or Kubernetes containers. This can be done with Cloud services like Google, Amazon and many........
  • Vbox Virtualbox DNS NAT Network Mode NOT working


    There is a random bug that sometimes occurs with Vbox NAT mode DNS, although it has never happened in the past and Vbox was working fine until recently. The symptom is that you can see it does get an IP+ DNS from the Vbox NAT DHCP. Below we use resolvectl dns and verify the DNS server is set to 10.0.2.3 which is the DNS from Vbox NAT. We can ping it but it does not respond to any DNS requests when we use dig @10.0.2.3 realtechtalk.com........

    This would be crucial especially if the phone is hardened, not being able to reset or change settings could prevent a phone registering in a new environment or even when migrating from office to office. This applies even if you are trying to migrate the phone to another platform such as Asterisk/FreePBX etc... This guide applies to nearly all of the Cisco IP phones that you would use in CME or CUCM from several years ago including models: 9900, 9971, 8800, 8900, 8845, 8851, 8841........

  • XBOX 360 No Sound over HDMI Solution/Fix


    My XBOX's dashboard/firmware was from sometime in 2008 when I first bought the system. I mainly played using composite cables but at my brother in law's house we used HDMI. The very first time it worked, but then I bought some games that did some update and after that HDMI never worked. The symptoms besides having on sound is that your XBOX will show PC monitor resolutions but won't have any option to say you have a 720P or 1080P display, this means the XBOX firmware is fa........
  • Asus Eee PC 1000HE Crashed/Need To Recover/Restore Windows? Easy Solution is Hitting F9


    I'm not a fan of Asus and won't be buying another because of having to fight Asus over a bogus warranty denial (it's a long story but they only replied about how to RMA my unit weeks later on the EXACT day the warranty expired). Anyway, it's just a matter of hitting F9 to do this, there's no need to worry about booting from USB or CD (unless of course you want a different OS eg. Windows XP Pro, Vista/7, or a flavor of Linux or Unix). Also remember that you need to fully/properl........

    This is what the /var/log/cups/error.log says after my Samsung CLP-310N decided to stop printing. This is a new printer that replaced my CLP-300 and it has been working for a day so far. What happened is that I lifted the top part (not realizing there were rollers on it) and it stopped printing. The network activity light was flashing ,hitting the stop button didn't do anything. Even powering the printer on and off did not help. I have restarted CUPS and SMB on the........
  • Hard Drive Not Working/Not Detected By Your BIOS Anymore?


    I was starting to panic because suddenly my 1TB Seagate SATA drive wasn't working,I thought it was a BIOS issue because it seemed to have happened after I tried overclocking my Desktop too much. I tried powering down and waiting, but I still couldn't hear the drive spin up at all. I tried a second 1TB hard drive and it wouldn't work either. I checked all power connections again and again until one of the pins in the MOLEX connector popped completely loose. Th........
