The algorithm™ recommended me a video on the subject. But there is also a website with more details.
TL;DW/R:
A Jedi master is teaching young Padawans an important lesson on the Force. Towards the end, one bored and exhausted youngling challenges the master: "I don't get it, maybe I can learn it from a real Jedi master and just not from you!" The master, smiling, asks back: "Why is that?" The youngling points to the master's Padawan braid. The master, still smiling: "Exactly, because of younglings like you, I kept wearing the braid: to remind us, that there is always something to learn about the Force, for Jedi masters and Padawans alike. Lesson's over."
May the 4th be with you!

Humans are as free, healthy and happy as it is possible in nature, when they focus on work a single person can handle. Unhappiness and inequality stem from society and its need to forage, own, depend, compare and compete, which promotes innate human differences (e.g. in ability, preferences, talents).
Sometimes it may be desired to get packages from apt instead of snap,
e.g. the Chromium snap doesn't have hardware acceleration for video conferences.
# Remove all snap packages
snap list
sudo snap remove --purge $SNAP_NAME
# Remove cache
sudo rm -rf /var/cache/snapd/
sudo apt autoremove --purge snapd gnome-software-plugin-snap
rm -rf ~/snap
# Block snap from auto-installing
sudo apt-mark hold snapd
sudo apt install gnome-softwareDiscovered some old notes for software dev interview prep.: Database normalization!

Japanese for acceptance of both (im-) and perfection. Kind of suprising, since the Japanese seem very perfectionist to me. I guess, wabi-sabi is to balance the strive.

0 is best, meaning "no PWM". Otherwise higher frequency is better. Sensitive people may have issues with screens in the 250-500 Hz range or lower frequencies.
Isn't it ironic after decades of framing and "appeal to emotion" by media and PR, those techniques are now so universally used that the same organisations losing control are urged to provide "fact checks"? 😅

Today, I discovered three distinct cases of poorly written code in our team's code base. Each time it bothered me so much, that before improving, I checked the author of those lines: me, a year ago.

The philosopher Harry Frankfurt at Princeton University defined bullshit as talk that has no relationship to the truth. Lying covers up the truth, while bullshit is empty, and bears no relationship to the truth.

A good naming scheme is scalable, unique, and easy to remember. The purpose of these naming schemes is to name networked servers, wireless access points or client computers, but it can also be used to name projects, products, variables, streets, pets, kids, or any other project where unique names and rememberable names are required.
