Here are some things that you need to do to get Windows 10 running on a Debian host under KVM. UEFI Booting UEFI is big and complex, but most of what it does isn’t needed at all. If all you want to do is boot from an image of a disk with a GPT partition […] In my post on Debian S390X Emulation [1] I mentioned having problems booting a Debian PPC64EL kernel under QEMU. Giovanni commented that they had PPC64EL working and gave a link to their site with Debian QEMU images for various architectures [2]. I tried their image which worked then tried mine again which also worked – […] I decided to setup some virtual machines for different architectures. One that I decided to try was S390X – the latest 64bit version of the IBM mainframe. Here’s how to do it, I tested on a host running Debian/Unstable but Buster should work in the same way. First you need to create a filesystem in […] I just got a 15.6″ 4K resolution Desklab portable touchscreen monitor [1]. It takes power via USB-C and video input via USB-C or mini HDMI, has touch screen input, and has speakers built in for USB or HDMI sound. PC Use I bought a mini-DisplayPort to HDMI adapter and for my first test ran it […] If you have multiple PHP web sites on a server in a default configuration they will all be able to read each other’s files in a default configuration. If you have multiple PHP web sites that have stored data or passwords for databases in configuration files then there are significant problems if they aren’t all […] Bruce Schneier wrote an informative post about Zoom security problems [1]. He recommends Jitsi which has a Debian package of their software and it’s free software. Axel Beckert wrote an interesting post about keyboards with small numbers of keys, as few as 28 [2]. It’s not something I’d ever want to use, but interesting to […] The Bulwark has an interesting article on why they can’t “Reopen America” [1]. I wonder how many changes will be long term. According to the Wikipedia List of Epidemics [2] Covid-19 so far hasn’t had a high death toll when compared to other pandemics of the last 100 years. People’s reactions to this vary from […] For some years I’ve had SquirrelMail running on one of my servers for the people who like such things. It seems that the upstream support for SquirrelMail has ended (according to the SquirrelMail Wikipedia page there will be no new releases just Subversion updates to fix bugs). One problem with SquirrelMail that seems unlikely to […] In considering storage trends for the consumer side I’m looking at the current prices from MSY (where I usually buy computer parts). I know that other stores will have slightly different prices but they should be very similar as they all have low margins and wholesale prices are the main factor. Small Hard Drives Aren’t […] I just did a quick test of different compression options in Debian. The source file is a 1.1G MySQL dump file. The time is user CPU time on a i7-930 running under KVM, the compression programs may have different levels of optimisation for other CPU families. Facebook people designed the zstd compression system (here’s a […] |
