Wed, 06 Jul 2022 20:40:00 +0000

GIMP at HiDPI screens

Tue, 14 Sep 2021 14:29:00 +0000

GIMP (2.10) has very small menu fonts on my screen which barely readable. I cannot found a way to increase the font size in the Preferences, how-ever editing the theme file is a easy quick fix. For example for the 'System' theme: ```bash $ diff -u /usr/share/gimp/2.0/themes/System/gtkrc.orig /usr/s...

Foscam VMS not showing device username/password

Mon, 12 Apr 2021 20:27:00 +0000

I changed a username/password to of one of my foscam devices, which I forgot to write down. The password was stored in the 'Foscam VMS' application, how-ever the GUI did not allow me to retrieve it. Luckily for me the application was written in .NET and was very well debug-able. With tooling like [...

Microsoft Teams meeting without looking at yourself

Tue, 06 Apr 2021 12:49:00 +0000

I find looking at myself when attending an MS teams call really distracting. It feels like looking at the mirror how-ever with just a very small delay. Apparently I am [not the only one](https://microsoftteams.uservoice.com/forums/555103-public/suggestions/36329914-move-or-turn-off-selfview-in-a-te...

Brother DCP-L3550CDW printer not printing

Wed, 10 Feb 2021 21:45:00 +0000

My DCP-L3550CDW printer was not printing multiple copies of the same document when asked via LibreOffice using the default (driverless) driver. It is most likely caused due to the fact the default driver does not implement the [collate CUPS feature well](https://cgit.freedesktop.org/libreoffice/cor...

Typing the shortcuts to your home directory with the tilde (\~) sign, requires an extra space after the character [when using an 'US International keyboard' layout](https://en.wikipedia.org/notes/Dead_key#Dead_keys_on_various_keyboard_layouts) which could be rather annoying since I type a lot.

I recently [found out](https://twitter.com/natfriedman/status/1271253144442253312) the term 'master' as repository name is considered offensive, since it is often used in conjunction with the term 'slave' Which in hindsight is indeed [not correct to use](https://en.wikipedia.org/notes/Master/slave_...

How-ever recently the key-binding is hijacked by the emojicon hipsters on GNOME to allow inserting emojicons. To re-claim the key-binding, use \`ibus-setup\` and head to the ...
