Wer einen lokalen Minecraft Bedrock Server betreibt und das Problem hat, dass sich Android Clients verbinden können aber iPads mit der Meldung “Keine Verbindung zur Welt” streiken, sollte die Firewall prüfen. Im iOS sind diese etwas versteckt unter den Datenschutz Einstellungen zu finden: Einstellungen -> Datenschutz -> Lokales Netzwerk Dort muss der Eintrag Minecraft auf aktiv stehen, damit sich Minecraft im lokalen Netzwerk nach einem Server umsehen darf.

Note to myself: Using xargs with wildcards needs to be wrapped in a shell command. When trying to move all unpublished blog posts and their thumbnails to an archive folder I used the following commands: mkdir -p content_archive/post cd content/post grep -l -i "published.*false" * | cut -d'.' -f1 | xargs -i'{}' sh -c 'git mv {}.* ../../content_archive/post' Explanation: mkdir -p content_archive/post - create the archive directory and create parent directories if they don’t exist (-p) cd content/post - enter the blog post directory grep -l -i "published.

Long time no see. The last days I had some spare time and checked out different static website generators. I got stuck with Hugo and converted my existing website mcbachmann.de and my blog blog.mcbachmann.de to Markdown by using ExitWP for Hugo. After several rounds of learning the peculiarities of Hugo, integrating the existing pictures and reformatting the generated Markdown files I’m now finally able to manage my website with simple text files and don’t have to care about WordPress updates.

Today I released my project that shows how to build a display that can be remotely controlled via CAN bus. I plan to use it as Smart Home remote control. For interaction with the controller it has a rotary encoder attached that emits CAN bus messages for different actions. With this setup, a remote counterpart like the Raspberry Pi can supply an interactive menu. The project is hosted on GitHub: https://github.

While trying out MX Linux 19 Beta on my old Thinkpad X60s I saw that the volume keys did work but don’t show up as OSD. After googling a bit I found Thinkpad-Wiki which suggests writing echo 0x00fc7fff > /sys/devices/platform/thinkpad_acpi/hotkey_mask into /etc/rc.local before exit 0 and reboot. That solved it! Thanks.

I’m using an old Brother DCP-135c with saned over network to scan my documents. After upgrading to newer Ubuntu versions the setup doesn’t work anymore and says invalid argument. After some tests which involved root permissions it turned out, that saned simply had no permission to access the device because the line GROUP="scanner" in the file /etc/udev/rules.d/60-brother-libsane-type1.rules was not enabled.

If logged in into a SSH server with a running desktop, the GPG tool doesn’t show any password dialog when trying to decrypt a file in an SSH session. It just stalls at gpg: AES encrypted data. User grawity shows a solution on superuser.com where the PIN-Entry tool of the GPG agent can be set manually. My adaption now looks like this and works like a charm: File: ~/.gnupg/gpg-agent.conf pinentry-program /usr/bin/pinentry-curses Reload the GPG agent configuration with the following command and you’re done:

I own a Snom 821 VoIP phone which is connected via SIP to my FritzBox. The thing I like most on Snom phones is the easy to access API. One thing that isn’t available easily is the defined set of the DND status. The online Snom API has a lot of HTTP requests to control the behaviour but for DND it just allows to simulate pressing the button. For my use case “set the phone to DND at night” thats not enough as I can simply not tell if DND isn’t already enabled by a direct key press.

I recently installed Ubuntu 18.04 on my nearly 10 years old NAS Intel SS4200. After upgrading from Ubuntu 11.04 the harddisk LEDs stopped working and the boot log just showed an Oops when the leds_ss4200 driver was loaded.After some investigation which involved compiling the module by myself and adding a lot of debug I found out that the pci_register_driver didn’t run the drivers install function but the later code assumed that a global pointer was filled and ready to be used.

After installing Ubuntu 18.04 I’ve got very large emoticons (see title picture). To fix this I followed the advice from User TuXFrk (Ubuntu Mate Forum) who installed the package fonts-symbola. After that you’ll lose colored emoticons but they will fit into their line: apt install fonts-symbola
