Crosh and Web Fonts

Crosh, the Crostini shell, uses CSS to render the terminal. Gives you nice capabilities, but it’s also not compatible how normal Linux is configured. Zsh and in particular the PowerLevel10k theme uses Unicode characters quite a bit. So step 1 is using a font which works: Open the crosh terminal Control-Shift-P In the Text Font

Fixing a Nintendo Pro Controller – Part 2

While I ordered a replacement joystick potentiometer slider (see my post from last week), I thought that you could also simply move one slider from a less used joystick axis to the one used most (left joystick, up-down direction). Much less used is the right joystick up-down). So I open the joystick again, bent off

ESP8266’s smaller brother: ESP8285

I forgot I bought one of those a while ago! To flash Espruino software on it: Files from https://www.espruino.com/binaries/espruino_2v05_esp8266/. Source: http://forum.espruino.com/conversations/319660/ although that speaks of 40MHz. I have not seen any issues with 80MHz. Needless to say, it works fine:

Fixing a Nintendo Switch Pro Controller

Came across this thread on reddit about fixing the Pro Controller for the Nintendo Switch. While I don’t have yet a problem, it’s good to know what fails and how to fix it when it happens. The main information is in those pictures. The sliders are actually replaceable without having to de-solder the joystick. Get

RouterOS and SSH

I got 6 Mikrotik RouterOS devices in active use now. 4 more which are not used. Time to make backups of their configs… Setting up ssh keys Making a config dump

Kubuntu 20.04 and Japanese Input

Enabling Japanese Input Method is always something which takes me more time that it should. Here the short version: Install ibus-mozc: apt install ibus-mozc Run im-config (it’s interactive) Log out and back in (all this is only active after re-login). For good measure re-start your X server (Ctrl-Alt-Backspace if enabled). You should now have the

Fixing DNS Resolver on Kubuntu

systemd is nice in principle, but it does not always improve things. E.g. why does it need a DNS resolver? Fix #1 This will get rid of the initial DNS name not resolvable error I see sometimes: Change /etc/nsswitch.conf and remove in the hosts line the “[NOTFOUND=return]” Fix #2 This removes the local DNS proxy/cache:

Creating TLS Certificates for Home Use

I used to create self-signed certificates, but they have the problem that I have to accept them the first time when using a browser, and when openssl library connects, I have to disable the certificate verification in curl, Node.js etc. The proper fix is to create your own CA which your computers trust. Then signing

Impact of Changing 5GHz WiFi Channels

My routers do DFS really well. So well, that they detect radar once in a while (about once per week) where I am pretty sure there is nothing to detect. I found a map of weather radar stations in my area (100km around me) and their frequencies. I should not be able to detect weather
