In other Nixie news, I picked up a Keithley 160 today. Here it is (middle instrument) measuring 10V out from an HP 6114A precision power supply. My Keysight U1282A reports the output as 10.009V. Nothing's been warmed up in advance. I just turned it on to see it all run, but it hasn't changed since it was cold about 20 minutes ago. Good stuff. Just needs a little adjustment.
Nice! The Keithley appears somewhat red on the photo. There's no need for it to feel embarrassed that I can see, though.
The only good thing about this revolving date pagan event is the reduced guilt of buying and eating Chocolate
Jittery indeed. I have nightmares about RFC 5545 recurrence section
Well has an interesting morning here. Got up, slipped over on some pens my youngest left in the middle of the living room carpet and spent a chunk of it in hospital. Sprained elbow. Fun. Not
A tribute to the NHS and London here. If you’re going to fuck yourself up, do it on a bank holiday. 7 minutes there on the bus, Took 5 minutes to triage, 5 minutes to X-ray then 20 minutes to see consultant. 15 minutes home on bus via pharmacy to get some naproxen. Bingo. Total cost < $15 in dollarydoos.

What's particularly bad about recurrence, compared with all the other messes associated with dates and times?
I've had occasion to drum into people just how awkward date and time are. Start with the easy questions like "how many hours are there in a day?", and proceed to more obscure questions.

Ouch. Daughter broke her elbow like that (avulsive fracture).
I've still got some naproxen from a a few years ago. I expect it is out of date, but it is comforting to have it in the "store cupboard" along with all the other items that might become difficult to obtain.
Ouchy no heavy Tea for you for a bit

Recurrence is a nasty one. Here's a real world anecdote.
It forces the question of "how do you store it" which turns out to be very difficult if you are a typical CRUD programmer (99% of them). The naive SQL-obsessed person takes the RFC and implements a piece of code which writes each occurrence of the event to a table. That is until a client comes along and accidentally adds one event every hour until the year 2150. This all happens in a nice little for loop, IOPS go through the roof and the operations team go purple. The next naive manager comes along and adds a restriction which shoots the clients down who legitimately have an appointment every week for the next two years by saying that they can't schedule more than a year ahead. Clients go purple. Then someone decides it's a fantastic idea to add attachments to this and subcontracts this out to the lowest bidding outsourcer who decides a chunk of it needs futzing around. About 3 months later, the operations team suddenly go purple again as all the CPUs on all the nodes are rammed at 100%. Well it turns out that a DST change and a poor understanding of time zones meant that all events an hour long had collapsed to 0 minutes and kicked off infinite loops on every node causing thread pool starvation and total platform outage and some steaming crashdumps and purple customers.
This is when I usually get dragged in to work out what the fuck has gone on. Stage one, discover that the start event is stored in UTC and the end of the event is stored in local time. Wowsers. Unravelled that one in a couple of hours. Stage two, add some circuit breakers and unit tests to cover the infinitely loop condition. Stage three, design a sparse storage model which (a) abstracts the entire RFC 5545 model (b) scales to 20,000 concurrent users (c) has no arbitrary event recurrence limitations (d) works across different timezones (e) can be slid into the existing fucked up mess of spaghetti written by the outsourcers. Then obtain a suitably sized LART and educate everyone involved while navigating politicians, bringing down a whole chain of CYA and generally Hulk smashing everything into oblivion in the way of it.
Horribly complex due to humans of course.
[Test]
public void TestDoesBD139ThinkThisIsGoodEnoughToRelease()

Totally agree. TDD is easy to subvert though:Code: [Select][Test]
public void TestDoesBD139ThinkThisIsGoodEnoughToRelease()
{
Assert.Fail("Hell no");
}

Or, more subtly, have tests that cannot fail. Or code which, in many places, simply catches and swallows occasional exceptions without finding their source.
Yup, I've seen that in fintech produced by UK developers. Nobody cared, even when it was pointed out to them.

Indeed. No sons. Three girls. Oldest two are going shopping today. Joy to teenagers. Zap them some cash and it's sorted.

Yep, that is SOP for me when I did tant changes on 465/475.
Good grief HP Nixie counters are still fetching big money. HP 5221B closed at $101.50 plus shipping.

You can't complain too much, you do have a much better chance of finding those counters than we have over here.
This is the only HP Nixie one on ePay UK at the moment, but unfortunately the price has the decimal point in the wrong place.

That depends on what they spend the cash on
I was lucky: at 14 my daughter and friends were just discovering local regional shopping centres and thinking they were fun. Well, OK - but there is more to life than that.
Fortunately I decided that my 50th was coming up and I really ought to go gliding - so we learned together. Great fun, she wanted to do things with me for longer than would have been the case, and the non-flying experiences were wonderful for her CV. Winner all round.
But she still thinks my test equipment is worthless, and makes the point that "if people like you are buying stuff from your youth, what will be the resale value when you all want/need to downsize?". Difficult to counter that, especially since the "downsizing" is the diplomatic scenario!

What? "For parts or not working?"
This has got to be a joke.
They're all quite sensible now, well mine are anyway; I can't speak for other people's children. Certainly better than my generation. Shopping isn't seen as a productive activity now because money is better spent on other things now that the Internet has shown how much things really can not cost. I expect it's probably different outside London as well. Also conspicuous consumption appears to have declined finally!

I would love to go and do something like that. We did abseiling the last time. That form of controlled falling was cheaper . I may revisit PPL as well. Prices for renting a Cessna out for the day and the tuition are starting to look more affordable once the mortgage is gone. That would make a good family activity too.
I'm considering putting a £15 offer on it
