As you might know, Raspberry Pi 3/3+/4 all have a 64bit CPU but Raspbian (the official and default system for the Raspberry Pi) is 32-bit. In this guide I will show you how to switch the kernel to 64-bit, however I only recommend doing this with the latest Rasbian Lite [...]
We can do this easily using curl, Gotify and a crontab one-liner (cronjob)! I'll show you how! This assumes you already have Gotify installed and set up, you can get the server and app for free on gotify.net (yes it's self-hosted)! Sign in to your Gotify server's dashboard, and then [...]
This is just a quick one, as I always find it annoying to not have numlock enable automatically on Linux desktops. Overview (all distros) You will want to install the application numlockx, and then add it to your startup applications (the name and command of the entry being simply numlockx). [...]
The Tor Browser for Linux comes as compressed tarball (.tar.xz) which you extract somewhere, however it does not add itself to the start menu. I'll show you how to add it yourself! So let's say you just downloaded tor-browser-linux64-9.0.10_en-US.tar.xz and extracted the folder tor-browser_en-US somewhere (I recommend to extract it [...]
The Nextcloud client does add itself to autostart on Linux, however I don't see a tray icon by default. I'll show you how to fix it. After the installation, Nextcloud creates a bad entry to the "autostart", which needs to be replaced with the correct entry as follows: Go to [...]
Sometimes you have to SSH into different devices with the same IP address, for example when you flash routers with OpenWrt and want to do initial configuration. One annoyance with that is fingerprint checking, as the fingerprint will be different for every new device but the IP will stay the [...]
You can find out really easily with one simple command: systemd-analyze Which will output something like: Startup finished in 9.708s (firmware) + 3.692s (loader) + 46.909s (kernel) + 13.614s (userspace) = 1min 13.924s graphical.target reached after 12.063s in userspace So as you can see, my laptop takes ages to boot. [...]
Not all my FIDO U2F keys (for e.g. Yubikey) were working under Linux and as it turns out, I had to add UDEV rules. I'll show you how. First, which rules you have to use depend on your UDEV version. You can check your version with: sudo udevadm --version All [...]
You might want to have your own /etc/resolv.conf but it keeps getting overwritten or lost. I have the solution! On systems like Ubuntu 18.04, by default the file /etc/resolv.conf is controlled by systemd-resolved. Usually it fetches the DNS servers and domain name (search domain) from DHCP and writes it to [...]
You might want to check what packages you installed on OpenWrt, for example when wanting to build a custom image based on your installation or to restore the packages after an upgrade. I found a neat little script that lets you do just that! The script I found on a [...]
