Thank you. It is mind boggling to me how politicians and scientists (well, mostly MDs) keep talking about exponential growth and make horrible predictions, without realizing that exponential growth is never sustainable - a logistic growth i

In interviewed at a local startup [1] and had a nice chat with one of the founders. We talked about 1h. It was pleasant and I got a code review assignment, timeboxed to 1h. Not sure if I managed to do something useful, but I handed back my

Sam Zeloof is building ICs in his garage. His blog and youtube channel are excellent and he has now a quite sophisticated process that produces reliable results, quite astounding really: http://sam.zeloof.xyz/

Phil's lab is the first thing that came to my mind when seeing this. Phil is an excellent teacher and has great content on PCB design, digital filtering, signal processing, C programming, FreeRTOS etc. Certainly an engineer that I woul

I agree. I enjoy socializing, but it never even crossed my mind that my job isn't doing something for someone else. This hypothesis is quite easy to verify: the sets of activities that I perform at work and in the time I have full cont

Ah yes, Agile-Fall! Of course, the agility here happens by accident, because in the first week of the program increment you realize that something is much harder than anticipated, and hundreds of person-hours of planning are thrown overboar

It's just like nutritional science. Only the time scale between the changes in recommendations is now weeks instead of years, and instead of recommendations it's laws.

Sadly, it looks like I was: "Thousands of health workers across France have been suspended without pay for failing to get vaccinated against Covid-19 ahead of a deadline this week, Health Minister Olivier Veran said Thursday." [1]

by donquichotte 5y ago
As a cynic, I see this as a message to the healthcare workers that are unwilling to get vaccinated: you are replaceable, there are plenty of people waiting at our doors to take your jobs.

Tangentially related, is there a good open-source tool for handwriting OCR? I want to digitize hand-written notes and make them searchable. Google Lens does a really good job, but I'd like to remove the dependency on tools that I can&#

Rigidity of the frame is key for accurate and safe subtractive manufacturing. You do not want your frame to flex while a spindle is cutting aluminium at 20kRPM. See Marco Reps and Kris Temmerman on youtube, they built formidable high precis

Very cool project. I guess actual subtractive manufacturing can only performed on very soft materials like foams - I have an eShapeoko which is stiffer than this construction and the frame starts flexing quite easily.
