Kozmik1··on Ask HN: Who decided copy+paste should copy styling/formatting?
It's amazing that Microsoft works so hard on this bs, but does zero to have Excel support copying newline separated (or comma separated, otherwise clearly dilineated) text pop into Excel properly on paste, something that would actually be useful!

What is the annual maintenance cost on a Mercedes?
Kozmik1··on IBM open sources fully-functional Lego microscope design (2020)
I prefer to use AmScope objectives in my 3D printed microscope, but my kids find all kind of wonders using the cheap PiCam setup. I think it’s about equivalent to 20x objective magnification.

Actually the magnification is shockingly good, enough to find tardigrades and microorganisms. The Raspberry Pi Cam is the default low cost sensor option of the OpenFlexure 3D printed microscope which for less cost than this Lego kit competes with extremely expensive lab grade microscopes.

In OpenFlexure PiCam mode, the lens from the PiCam is removed and inverted and spaced at a distance, giving a higher magnification than the digital camera in default configuration.

Kozmik1··on Ask HN: How Is Your Neck?
I was beginning to have back pain this summer after working very long hours sitting and with a lot of stress, and I thought my general weakness and lack of exercise was to blame.

I started an 8-week push-up challenge in which I found my max amount of push-ups without stopping (30) and then did 4 times that many (120) in a row, however long it took, gradually reducing the rest time between the sets. I did this 4 days per week. After that process I gained a lot of strength in 8 weeks and ability to do 40 push-ups without stopping. I've now switched to doing my maximum once or twice per day and increasing by 5 every couple weeks. I'm currently at 70, having a hard time going higher, but really feel incredible level of upper body strength from neck to back to abdomen, and am being more careful with my food choices as well. I think I'm now ready to do some more varied exercises, including cardiovascular and other things that challenged me earlier.

I find as I'm getting older it's really not worth sacrificing your body for engineering gains, I have too many tech friends who have chronic and sometimes debilitating pain and injuries as a result of the career. What's the point of great accomplishments in technology, career, and wealth if you can't enjoy them because of a broken body?

I encourage everyone to find an exercise routine that fits your lifestyle. Push-ups were great for me because I needed no equipment and could fit it easily into my work from home day, and target the areas of my body that were feeling weak.

US Dad of 2. We had a doula for our first child, she was hugely helpful, even in a hospital birth. Highly recommend!
Kozmik1··on Ask HN: How can I make a “kid's computer” today as good as an Apple II?
I think the best learning experience is seeing you can still build and repair a computer yourself, so I had my 8yr old kid build his own gaming PC from scratch (with me standing by for guidance). We were about $1200 in with parts: motherboard, cpu, ram, nvme, chassis, dvd-rom, etc.

Then he got to help as we installed dual-boot Ubuntu and Windows, with Ubuntu being default :)

In windows I installed some games I felt ok about. Microsoft Flight Simulator, Kerbal Space Program, Pokemon TCG, his school office apps. But I only let him run Minecraft on the Linux side, so he will have to boot there and sort it out from time to time, with the bonus of a Minecraft server environment we've hacked a bit.

We're no longer in the 80s, that's for sure! But I think focusing on learning the components of hardware/software in computing are better done on a desktop than a laptop or tablet. There's really nothing to be learned in today's repair-hostile walled gardens.

Kozmik1··on Ask HN: Who has moved from the U.S. to Europe?
Can anyone moving from the US to Europe speak to the non-white experience? I’m interested in the UK specifically. We understand that the UK has some pretty harsh anti-hate crime and anti-hate speech laws on the books, but what is life like as a professional American person of color making a change from the US to the UK?

Is anyplace outside London considered inclusive?

Kozmik1··on The “Granny Knot”
Try the Surgeon's Knot instead: https://www.fieggen.com/shoelace/surgeonknot.htm
Kozmik1··on The “Granny Knot”
As others have mentioned, Ian's knots has great reccommendations, but overlooked is the "surgeon's knot".

This one has two twists instead of the normal one, and comes out like a square knot if done right. It won't come untied by itself, ever. But you can untie it by tugging on the tails of the laces. You can do this one with a thumb on the initial bend, unlike the "bunny ears" style knots.

It's a hell of a lot better than the "double knot" your kids' teachers will do if they go to school with any kind of single knot, square or not. Double knotting just results in big jams when one tries to untie it later.

We've been looking for a good bathymetric layer (with depth contours) for Leaflet. Has anyone done this?
