Back in 2012 I built a PC around the Intel i7 3930K 6-core/12HT processor which I have been using ever since. While it’s still a strong PC, especially with the upgrades (GPU, SSD) I made, I’m starting to feel that editing photos isn’t as snappy as it used to be. I am also curious in how well the new generation of CPUs lend themselves to VGA passthrough. In short, I’m considering building a new PC.Continue reading “New PC Build”

The funny thing was that I could boot into Linux and run some applications, and whenever I used Firefox I would sooner or later get a freeze. I monitored the processes and saw that the kswapd demon was busy. It took me a little to grasp that I had “lost” memory.Continue reading “Memory Failure”
In my Running Windows 10 on Linux using KVM with VGA Passthrough VFIO tutorial I introduced different options for using the keyboard and mouse with the Linux host and the Windows VM. Running a virtualized Windows VM means running two separate systems – the Linux host and the Windows VM – both of which require input and output devices.Continue reading “Virtualization Hardware Accessories”
I’m the type of person who is learning things the hard way. This is also true for me buying computer equipment and peripherals. I cannot even recall how many times I have replaced my computer mouse and keyboard in the last decade.
One should think that a mouse or a computer keyboard aren’t exactly rocket science – well they aren’t! Yet many popular mice or keyboards are either bad by design, or fall to pieces within a relatively short time.
Below is a list of things you should be checking when buying a computer mouse or keyboard. It is based on my personal experience – your experiences may be different, though.Continue reading “Keyboards and Mice”
