Yeah the Tek scopes were made before they came up with them though which is annoying. I usually replace them with the Harwin gold plated turned pin ones as I got a massive box off them from eBay for virtually nothing :)

Annoyingly the IC sockets tend to oxidise if the board doesn’t! I’ve lost count of the number of them I’ve had to replace in my life. If it wasn’t for mechanical switches, pots, contacts and some dubious thermal design I imagine the kit wou

But that’s not the case. The root cause is the MFT and NTFS architecture. People fail to mention that because the problem is harder to fix. It’s almost that there is a “do not speak bad of NTFS” going on. You can demonstrate this by using a

You can do TDR (cable measurement) with 74LVC series easy enough. I built a nice little pulse generator fixture for this and use it with my Tek 475A (1.4ns risetime). Also 74AUC has Tpd of 300ps at 2.5V. I don't get why Potato even hav

I think that’s because they want the bits you can’t see to look as good as the bits you can. I rather like poking around inside apple kit. Always have a smile on when I have to.

Also lots of boards had transparent solder mask after that (Tektronix did this) which was great for debugging! Examples here: http://golddredgervideo.com/kc0wox/tek/7504/detailedpictures... Whole scope is a w

Actually OSHpark boards I find are pretty crap. They have mouse bites left over, the mask is crap and the registration poor on some boards. Getting better boards from JLC but you lose HASL and purple.

I can’t see MFT contention mentioned once. That’s what absolutely and totally destroys small file write performance. This affects source operations, WSL, compilers, file storage, everything. And that’s so architecturally tied to the guts of

This made me snigger perhaps more than I should do. I wonder if the people selling this shit actually know or not. They have to I suppose.

That was absolutely amazing. Thanks for posting.

Euro NCAP will be mostly “nope”. It’s not that the Chinese can’t build decent cars (Qoros 3 got 5 stars) but definitely not at that price point. Also no dealer, service or parts supply here in Europe so no thanks. Stick with my Citroen.

Accept it or change it. Accepting it is transitioning from the realisation that you’re doing it because it’s interesting to doing it because it pays the bills and funds other interests. Changing it is transitioning something else into the p

My apologies to the readers of HN. I will bear this in mind in future.

The stasi kept the data protected better than a lot of tech companies as well.

We're getting pretty good at being examples to the rest of the world of what not to do recently. Might as well sink our ship in style.

Any public references for this anywhere?

I may be older than you :) When I did secondary school "technology" which was the overseeing subject, we used BBC basic and 6502 assembly (some of us anyway!) to drive CNC equipment and Lego and spent half of the time with a solde

Good. The equality that was fought for does not mean being granted a license for hypocrisy. Edit: sorry was that the wrong kind of equality I subscribe to?

Some schools. My eldest did python on MacOS here in UK secondary school.

I think the worst place I ever worked was like that. Was going back quite a number of years now but it was a startup fired up by a one of the lesser MBAs to utilise a legal loophole to slice cash off the public via a web app and a metric to

They do explode quite violently still. I’ve blown up tens of new ones. Try an average Chinese or even rubicon 10uF 63v ish cap which is in just about every bit of crap from SMPS to cheap toys. They go with quite a Big Bang.

I think we hugged it to death based on the 404... :(

When they’re not screwing it up: https://github.com/dotnet/cli/issues/3093#issuecomment-44343... I suggest anyone interested reads the entire thread.

I'd blown up a few myself by then, mostly on purpose :)

My grandfather was the opposite unfortunately. We found a radio power supply he made, I carefully but not carefully enough reverse engineered it, brought it up slowly on a variac and after three minutes it exploded violently spewing capacit

Indeed. Reminds me of the book by Jim Williams on analogue Design via anecdotes. There was a picture in there of a broken Tektronix 453, lab notebook, tools, pizza and coke and a caption saying “life doesn’t get much better than this”. I wo

The whole packaging process is a bit wonky. I’ve had a couple of broken or buggy builds on Debian.

Telemetry and packaging are the big ones.
