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 hard problems he was discussing were completely solved by the a

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 dramatically. It happened silently, such that I didn’t realize wha

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 symbol-labelled buttons will do this without initiating a p

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 are typically made of stainless steel which has a pretty me

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 could be phrased in an algorithmic kind of way, please share! T

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 as a two-probe DC measurement, so once you factor i

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 helpful for removing parts - it tends to leave behind just eno

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 it. Half the price in small quantities and easier t

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 with the right atomic spacing AND dirac cones in the ba

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 kind of 'alternate history' nextgen game

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 from the fact that the shim is a sawed off

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 without eye-searingly bright front and backlights makes me very n

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? The default behaviour on the kindle seems to be to show me

'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 important to think hard about your reasons for getting into it.

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. It's really quite difficult to be a competent doctor, so yo

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 idiot?" etc it's actually a really fun problem to tackle. I p

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 think I agree with you there (or perhaps I just didn't interpre

Quite aside from any of the main points being made here, the guy is dead on about Strogatz's book. I had the same reaction to that book as I did to Lipovača's Learn You A Haskell - it's a great accessible resource to learn something new and

It's an issue of definitions. Of course you cannot build an electronic device using only a single atom, because you need leads, interconnects, power supplies, measurement equipment etc. So when you talk about a single atom transistor, what'
