absolute chaos on a new unmoderated listserv this week as tens of people used the ‘thumbs up’ feature in outlook, which apparently now sends an email, causing an unstoppable torrent

@mikarv Outlook, adding features to email that nobody ever wanted, nobody needs and break the base assumptions how email works since 1997.

Is this different from the regular Loctite, I wonder.

attilakinali,
@attilakinali@society.oftrolls.com avatar

@mansr The normal ones? No, they are regular superglue. At best, they have paperwork to prove that they do not contain anything really toxic. At best...

The non-normal ones use a different adhesive that can be resorbed, i.e. you don't have to remove them from crevices they got into. But these are not the stuff you usually get on amazon or your local pharmacy.

@mansr I don't think the rest-chain of the cyanoacrylates poses a significant difference in the behaviour of the glue. Maybe the longer chains delay the polymerization reaction a bit, which might be helpful in applications where things are generally very wet... like when there is blood around. AFAIK the first siture glues were off the shelve super glue.

After a very windy afternoon Puget Sound Energy is now tracking 140 separate outages across the region affecting roughly 22.1K buildings.

Lab is operating on generator power and some equipment shut down when a loose UPS EBM cable resulted in running out of battery before the generator started.

So much for a nice relaxing weekend. Guess it's an excuse to do some hardware maintenance I had been putting off trying to avoid downtime.

@azonenberg I think, the US having such an bad power grid is the best advertisement for small scale solar power anyone could wish for.

attilakinali,
@attilakinali@society.oftrolls.com avatar

@azonenberg If northern Germany has good enough weather to do solar at industrial scale, then all of the continental US are perfect! You not only have much more sunny days than northern Germany, but also a much higher angle at which the sun shines, thus giving higher output per m^2.

As for outages: It doesn't matter whether they a large scale generation/distribution problem or a small scale distribution problem. Point is you have outages and solar panels on your roof would solve both of them.

@azonenberg Divine Copulating Bovines! You have a huge power usage. The average single family home over here uses 3-5MWh/a. You are at 10 times that!

I guess, the only way forward would be to put up one of these 50m tall wind power plants. That should be enough for most days 😜

attilakinali,
@attilakinali@society.oftrolls.com avatar

@azonenberg Oh.. I see. Yes, if you have a fully equipped electronics lab running 24/7, then your power consumption will be high. Especially high-speed/high-frequency measurement equipment.

A few weeks back I encountered a FOSS guy here explaining that when he sees open source devs ask for money, he blocks them and then stops using their code because they're morally wrong and he only wants to work with tools made by people who are doing the work for the right reasons. (I'm paraphrasing to avoid indexing the post.)

I've resisted writing about it because I'm slammed, but the question I can't shake is: Who benefits from the ideology of "pure" volunteerism?

attilakinali,
@attilakinali@society.oftrolls.com avatar

@kissane As someone who spent over a decade write OSS, one that millions of people use every day, I can wholeheartedly say: f*ck this guy. We had so many bright and productive people who had to leave projects because they needed to put food on the table and after a long workday had no energy left to keep on coding for other people.

OSS has an idealistic aspect, but at the end of the day, everyone has bills to pay. They can either do that working on OSS or on commercial software.

"Sough" is a word I've seen plenty of times in writing, and I knew what it meant (make a sigh or woosh like wind blowing).

But I wasn't sure what the correct pronunciation was. I guessed it might rhyme with "through" or "rough" or "sow" or "so".

So I looked it up, and found three totally different pronunciations ("suf", "so" and "sow") listed as correct. Very unsatisfying!

Which do you prefer?

attilakinali,
@attilakinali@society.oftrolls.com avatar

@TerryHancock Dear friend. Please, use IPA when describing pronunciation. English is really one of The Wurst of The Wurst languages when it comes to describe pronunciation.

Until you correct your ways, you will not get any chocolate!

I keep seeing the news about lunar time presented as “the Moon is getting its own time zone." What's actually happening is the Moon is getting its own time standard. The problem being solved is that time passes slightly more quickly on the Moon compared to Earth (due to General Relativity) and so the Moon needs its own time standard for precise measurements and navigation. UTC is the time standard for measuring time on Earth, and LTC is being created for the Moon.

attilakinali,
@attilakinali@society.oftrolls.com avatar

@dgoldsmith You seem to be knowledgeable on this topic. Could you explain why we do not just compensate for gravitational red shift on the moon the same way we do for the various NMI labs that are at different altitudes and thus run at slightly different rates? Why do we need LTC when just using UTC with the correct definition of the second (i.e. defined at zero gravitational field) would be sufficient?

Dear Fediverse,

I am currently at a place with very German internet and a Berlin firewall. Ie everything but ports 80 and 443 are block

This means I can ssh home as I have an ssh server running on port 443, but I cannot run wireguard, as that runs on a different port.

I remember once reading somewhere that on can run ssh and wireguard on the same port and some multiplexing thingy would disentangle the two. But my google foo is too weak to find anything

Does someone remember how to do that?

@mansr That someone is me! I don't know how that happened, or when it happened. From the crust on everything, I estimate that it must have been more than a decade.

It also looks like a fuse failed to fuse and something else had to fuse instead.

Given the very sorry state of electrical installations in this state in general and in this building in particular, I am not surprised that stuff like this never got fixed.

At least, now it will get fixed.

Reasons why I love physical books over pdfs: I can clearly remember what a book looked like, even if I can't remember its title. Hence finding it is just a quite browsing of the shelves.

A pdf is just a filename. It has no color, no texture, no smell. (ok, the last one is a good thing). So finding a specific pdf depends solely on remembering its title, or bits of it. Which of the 28'000 pdfs in the 7000 directories is the one I'm looking for?

This toot has been brought to you by a 3h search.

TIL: Until 1971, he UK used imperial units for their money as well, because, obviously, it makes sense that 12 pennies are a shilling and 20 shillings are a pound.

(Most of Europe went "metric" with their money somewhen in late middle ages / early renaissance, at latest during Napoleon)

Whenever "right to repair" is mentioned, my first thought is of Loretta's right to have babies in Life of Brian. You might have the right, but you're never getting the means.

attilakinali,
@attilakinali@society.oftrolls.com avatar

@mansr I'm more confused about the how to get the information how to repair a device. I know how complex electronics can be. I know how electronics, especially consumer electronics, are getting more and more integrated. If you don't have schematics, you'd have to reverse engineer the whole circuit, which isn't easy. And even if you have a schematics, when the problem is in one of the 10 ICs that make up the whole thing, 5 of them being custom made, how are you going to fix it?

attilakinali,
@attilakinali@society.oftrolls.com avatar

@mansr
Would you consider a BGA rework station and stereo microscopes standard workshop equipment? Because that's what's needed even for basic repair on a modern PCB. Even most electronic shops don't have that stuff because the time invested in reworking PCBs, even their own design, is not worth it considering how quickly cost add up to more than the PCB is worth.

@attilakinali@society.oftrolls.com avatar

@mansr @emeb @C8H10N4O2 @flameeyes Exactly. But this isn't new. This has been plaguing radio and tv repairs already 20 years ago. And it has been only getting worse. I also don't see how this will change given that being repairable and being small are contradicting requirements.

Does anyone know if there is a piece of test equipment that:

  • Is generally oscilloscope-esque (measures voltage over time)
  • Has a ton of channels. Eight or ten minimum, ideally significantly more
  • Has high-ish DC input impedance (tens of kΩ) and low AC impedance (50Ω)
  • Input range of at least +/- 12V, ideally up to 48V or more
  • Fairly low BW specs by scope standards, I need maybe 10 MHz and something under 100 Msps.
  • >8 bit vertical resolution would be nice

I don't want to have to build it, but I don't think it exists. A synchronized pair of Teledyne LeCroy WaveRunner 8000HD scopes with RP4060 active power rail probes would absolutely meet the requirement, but be exorbitantly expensive for the lower BW requirement here.

Use case is monitoring and verifying power rail ramp up/down behavior on a complex board that may have 10-20 different rails, each with requirements for ramp rate, on/off ordering, etc.

attilakinali,
@attilakinali@society.oftrolls.com avatar

@azonenberg Why not use a standard 8 channel oscilloscope and add some DC block capacitors to the inputs? Though getting to 20 channels would be a bit cumbersome, even with syncing multiple oscilloscopes.

If any STMicro engineers follow me, I have a challenge for you.

Release a new STM32, any size, in which at least one IO bank is contiguous on die (i.e. Px0 - Px15 are on adjacent bond pads with no other pins in between them aside from Vdd/Vss) and, on packaged chips, is placed in at least roughly the same corner of the package.

attilakinali,
@attilakinali@society.oftrolls.com avatar

@azonenberg Poor SI? My experience is that QFP is pretty easy to inspect visually. Yes, it uses an awful amount of space, but otherwise it's a pretty tame packaging.
