Introduction It’s rarely necessary to make an issue of installing and maintaining the GRUB bootloader. However, for reasons explained in a separate post, I wanted to install GRUB 2.12 on an old distribution (Debian 8). So it required some acrobatics. That said, it doesn’t limit the possibility to install new kernels in the future etc. [...]
Introduction My Debian 8-based web server had been running for several years as an OpenVZ container, when the web host told me that containers are phased out, and it’s time to move on to a KVM. This is an opportunity to upgrade to a newer distribution, most of you would say, but if a machine [...]
General Exactly like my previous post from 14 years ago, these are random jots that I took as I set up a QEMU/KVM-based virtual machine on my Linux Mint 19 computer. This time, the purpose was to prepare myself for moving a server from an OpenVZ container to KVM. Other version details, for the record: [...]
Intro This is a super-short post, but I have a feeling it will evolve with time. Using ssh, pasting text with CTRL-V or the mouse’s middle button sometimes resulted in ~0 and ~1 around the pasted text. Super annoying. As it turns out, this is called “bracketed paste” and its a way for the terminal [...]
The problem I wanted to solve On an embedded arm system running LUbuntu 16.04 LTS (systemd 229), I wanted to add a mount point to the /etc/fstab file, which originally was like this: # UNCONFIGURED FSTAB FOR BASE SYSTEM Empty, except for this message. Is that a bad omen or what? This is the time [...]
Motivation I have an English / Hebrew keyboard, but occasionally I also want to use the Swedish letters å, ä and ö. The idea is to sacrifice three keys on the keyboard for this purpose. But which ones? I went for the keypad’s /, * and – keys. But hey, I use these normally every [...]
Introduction Having switched from ADSL to FTTH (fiber to the home), I was delighted to discover that the same script that set up the pppoe connection for ADSL also works with the new fiber connection. And as the title of this post implies, I opted out the external router that the ISP provided, and instead [...]
Introduction These are notes I made while trying to make my Sony WH-CH510 bluetooth headphones work properly with my Linux Mint 19 machine. It’s evident that an upgrade of the whole OS would have fixed the problem, but I have my opinion on upgrades. The problem: It takes a long time for the headphones to [...]
Introduction This is a spin-off post about failing attempts to fix the problem with a webcam’s keyboard buttons. Namely, that the a shaky physical connections caused the USB device to go on and off the bus rapidly, and consequently crash X windows. The background story is in this post. There is really nothing to learn [...]
Introduction There is a widespread belief, that in order to use git send-email with Gmail, there’s a need to subscribe to Google Cloud services and obtain some credentials. Or that a two-factor authentication (2fa) is required. This is not the case, however. If Thunderbird can manage to fetch and send emails through Google’s mail servers [...]
