… or any other “unsupported” Linux distribution. … or: How to trick the installer into thinking you’re running one of the supported OSes. So I wanted to install Vivado 2020.1 on my Linux Mint 19 (Tara) machine. I downloaded the full package, and ran xsetup. A splash window appeared, and soon after it another window [...]
Just a quick note to remind myself: There’s a gap between the size of a disk, the used space and the available space. It’s quite well-known that a certain percentage of the disk (that’s 200 GB on a 3.6 TB backup disk) is saved for root-only writes. So the reminder is: No problem filling the [...]
When to do this Because Gnome desktop is sure it knows what’s best for me, and it’s virtually impossible to just tell it that I want this screen resolution mode and no other, there is only one option left: Lie about the monitor’s graphics mode capabilities. Make the kernel feed it with fake screen information [...]
Upgrading the kernel should be quick and painless… After upgrading the kernel from v5.3 to 5.7, a lot of systemd services failed (Debian 8), in particular systemd-remount-fs: ● systemd-remount-fs.service – Remount Root and Kernel File Systems Loaded: loaded (/lib/systemd/system/systemd-remount-fs.service; static) Active: failed (Result: exit-code) since Sun 2020-07-26 15:28:15 IDT; 17min ago Docs: man:systemd-remount-fs.service(8) http://www.freedesktop.org/wiki/Software/systemd/APIFileSystems Process: [...]
I sent that? One morning, I got a bounce message from my own mail sendmail server, saying that it failed to deliver a message I never sent. That’s red alert. It means that someone managed to provoke my mail server to send an outbound message. It’s red alert, because my mail server effectively relays spam [...]
A short one: What to do if unmount is impossible with a # umount /path/to/mount umount: /path/to/mount: target is busy but grepping the output of lsof for the said path yields nothing. In other words, the mount is busy, but no process can be blamed for accessing it (even as a home directory). If this [...]
Introduction So I got myself an LG OLED65B9. It’s huge and a really nice piece of electronics. I opted out the bells and whistles, and connected it via HDMI to my already existing media computer, running Linux Mint 18.1. All I wanted was a plain (yet very high quality) display. However at some point I [...]
General These are just a few jots on Wine. I guess this post will evolve over time. I’m running Wine version 4.0 on Linux Mint 19, running on an x86_64. First run Every time Wine is run on a blank (or absent) directory given by WINEPREFIX, it installs a Windows environment. Which Windows version an [...]
Introduction Firejail is a lightweight security utility which ties the hands of running processes, somewhat like Apparmor and SELinux. However it takes the mission towards Linux kernel’s cgroups and namespaces. It’s in fact a bit of a container-style virtualization utility, which creates sandboxes for running specific programs: Instead of a container for an entire operating [...]
Introduction Still in 2020, it seems like Microsoft lives up to its reputation: Being arrogant, thinking that anyone in business must be a huge corporate, and in particular ending up completely ridiculous. Microsoft’s mail servers, which accept on behalf of Hotmail, MSN, Office 365, Outlook.com, or Live.com users are no exception. This also affects companies [...]
