It can go both ways of course. The first edition of Norman’s classic ‘design of everyday things’ was 1988, and it’s interesting to read that book today and see how a lot of the har…

It goes further than warnings though - at least circa 2012 using an unofficial charger (or official charger where this fragile extra wire is broken) would underclock the cpu dramat…

Along these lines, I admit with shame that lately I’ve been switching to airplane mode before looking up or modifying a contact, because it’s not obvious to me which combination of…

Al-foil is ubiquitous in ultra-high vacuum labs because part of the process of reaching this vacuum level involves baking the whole chamber at 120-150dC for 24+ hours. The chambers…

The three people are known to you in advance (it’s your group). It was common to game this a little by saving the biggest person as the third one that had to break the bridge.

Oh, really so much faster with pypy3? That would have been very nice to know when putting this together, but in any case is good to know for the future. Thanks for the tip.

Author here. I really wasn’t very good at SPL-T before I changed gears to brute forcing it, so the whole strategy aspect is unexplored here. If you think you have a method that cou…

This summary doesn't give numbers, but the journal article being discussed does. About 3e3 to 1e4 S/m for different preparations, compared with zero for untreated silk. Performed a…

You can see in the video that he does have desoldering braid, but has chosen not to use it. Sounds like our experience differs, but personally I find desoldering braid is seldom he…

This is because it just got published in Nature something, the earlier open arXiv version from April is here: https://arxiv.org/abs/1604.02265 Figure 3 is absolutely spectacular, a…

open arXiv version from April: https://arxiv.org/abs/1604.02265 Figure 3 is absolutely spectacular, and deserves to be admired by the whole world. A comment on the inevitable promi…

If anyone out there is looking for alternatives, last time this happened I switched to the MCP2221 from microchip. It's been in about 6 hobby projects now and I'm very happy with i…

Last year when I was looking into silicene it was all very controversial and nobody seemed to have given all the necessary evidence to prove they'd made it (i.e. honeycomb lattice …

I feel like the real lesson I learned here was not about time series but about reading the comments section for any discussion involving global warming

This is a really nice example of a project post/build log. Related, I think it would be a lot of fun to interface the Pi with the original (not very good) LCD. Then you could make …

Some time back I described a project to do this with a single data track ( http://www.flashingleds.net/swipecards/swipecards.html ) This was a crude first pass, which is evident fr…

It sounds like there might not be a 'next-time' in the near future, but maybe think about putting some lights on if you're doing another 3am start. Even riding my bike at 6am witho…

You know how sometimes you buy a second hand book and some jerk who owned it previously went through and underlined every second sentence, presumably for an assignment or some such…

'just because' doesn't seem like sufficient justification for spending 4-6 years working crazy hours for scant pay. It's a big sacrifice, so as other have alluded to it is importan…

The reason your analogy breaks down is competition. Usually it's pretty easy to obtain food in some shape or form, so there are near endless alternatives if you face steep pricing.…

I confess to trying this myself after reading the Srivastava story. If you step back from the fact that it's a lottery, there's plenty of money involved, "what are you a gambling i…

Regarding the point: "Just-in-time learning is the future. No ifs, ands, or buts. Any argument you might have to the contrary is not only wrong, but dangerously wrong." I don't thi…
