Covid-19 France – le point mi avril 2020

A Board for Paper-Based Spaced Repetition Memorization

I’ve been using spaced repetition for quite some time now. My favorite program is Anki, even if I have also tried a few others. I had actually developed one myself before I even knew the SuperMemo algorithm existed back in the late 1990’s, that was more than 10 years before the first Anki release. Interestingly, … Continue reading “A Board for Paper-Based Spaced Repetition Memorization”

Planned Obsolescence, 0 – 3D Printer, 1

It is not the first time that I fix something with 3D printing. But this one was an interesting one! The problem A few years ago, I bought two stands for my microphones. Okay, they were inexpensive, and maybe it was a bad long-term choice. Maybe I should have opted for more expensive ones. But … Continue reading “Planned Obsolescence, 0 – 3D Printer, 1”

A Strange Rubik’s Cube Story

Two years ago, my wife offered me a very nice gift: While that was a great gift and the kind of challenge that I would take on, I felt embarrassed as I even had no idea how to solve this: Right.

Learning words in foreign languages

Recently I was asked how many times you should hear a word in a foreign language before it really sticks into your mind. Sometimes, hearing/reading one word one single time in the right context will imprint it into your mind forever. And sometimes, you will repeat one word 100 times and it will not stick. … Continue reading “Learning words in foreign languages”

3D printing – part 1

I have been curious about 3D printing for a few years now but never found the time and courage to finally take the first step and buy a printer.
