when is GCC gonna have support for shock collars?
it might help to shock the programmer whenever the compile fails

@gooba42 panic("Splunge!"); was more useful than some other error messages I've run into.

Earlier today I had something that kept spitting "Access violation" over and over like a fountain. No details, not even any description of what function was throwing it.

On an unrelated note I want a big heavy leather collar that actually does serve as a grounding strap as suggested in that old story

Wow, modems got TURBO JANKY for a while, didn't they... Supposedly this is just a PCTel reference design, with pretty much everything not absolutely needed stripped off.

In case you're wondering how these worked without an isolation transformer, the secret is in the "Silicon DAA" design. Everything on the phone line side of the modem is powered only by the DC voltage on the line. Serial data communication back to the PCI interface chip is passed via the seemingly random value 2KV rated ceramic disc capacitors.

In case you are wondering if this worked at all: yes, in most cases.

In case you are wondering if this was any good: lol NO

ceramic disc capacitors for data transmission

I saw this voltmeter at the electronics flea market. Look at that massive probe! It looks like you need to check your back blast before using it.
Apparently it's for REALLY high voltages? Like, 3kV?

@vxo@digipres.club avatar

@foone I'd go up an order of magnitude at least, you wouldn't need it that big for 3k. The little TV repair sized hv probes you probably saw around in various places are made for like 30

@foone ugh I would love to invite people to instead become keyboard builders! Leave the vintage hardware alone and instead score a custom keyboard that is exactly what you want it to be.

I want to build a nice split mechanical that looks like the neon shimmering on a rainy night. :3

I feel like I have never been seen before about my desire for a proper mainstream Android phone with a hardware keyboard than on Fedi

It feels like for the longest time I was the only one, but being on Fedi has shown me that… Wow… A LOT of people want this.

If there's one thing I know from '90s kitchens and bathrooms, it's that no one ever actually uses or eats the aesthetic stuff in fancy jars. That soap? Nah, that's the decorative soap. It's here to look pretty, so don't use it. We're out of noodles, too—those in the jar are strictly decor. https://www.eater.com/24105047/you-dont-need-to-decant-your-groceries-kitchen-storage

Little secret about datacenter water usage: they actually don't USE nearly as much as they report-- they DRAW a lot of water yes, but they'll only cycle it a few times before giving it back, either through waste pipes or other ways, otherwise you get sediment buildup in the pipes and heatexchangers. The average golf course uses far more water, and actually uses it without returning any of it

And the alternative, is to use energy-heavy AC/heatpumps, which due to public outcry, is happening more.

@anthropy where is it used anyway? evaporative cooling towers?

I'm looking for recommendations for things to help introduce someone to the world of electronics, both instructional materials and hands-on activities like kit building. I've run into a few people now who are really interested after learning about some project, like console modding or repair, and would love to increase their knowledge.

Someone on tumblr asked why 3.5" floppy disks seem so much more friendly (or "pleasant and edible" to use their terminology) than 5.25" floppy disks, so I wrote about it:

https://www.tumblr.com/foone/750216135935492096/why-do-35-inch-floppy-disks-seem-so-much-more

TL;DR: It's because Sony.

@ai6yr are you sure? I mean really all you'd need is to construct a long pool with a couple of circulation pumps pushing the water through it so it can propel a raft around :D

Some weirdo or weirdos is retransmitting the entire broadcast of a local TV station and a local radio station on ham radio here in LA. They've been doing it for many days now.

@MLE_online oh, that nonsense. hah. We had a jammer like that in Miami for a while, they'd settle in on a frequency at complete random in the afternoons.

That's assuming it isn't just some intermod product drama

@recursive I have enough that I could easily bench test an old analog broadcast console that needs +/-18, +/-12, +5, and -48 (though this is usually optional and only needed if you are using the internal mic preamp and condenser mics)

I forget which the goofy one was I was working on that needed +/-18 and +/-12

Ok it's time for a thread about the sencore AT985 atsc RF monitor, tbh first time I ever heard about atsc so no idea what format is that, but hey look! a floppy drive.

@kiwa some examples of the eye and constellation patterns can be found in this thread https://www.avsforum.com/threads/8vsb-rf-waveform-display.2960126/

the constellation at least, uh, looks like all the right parts are there - it should ideally be concentrated on the 8 vertical lines. When the dots start falling more left and right of them that usually implies weak signal / terrain impacts on the received signal, multipath, or distortion at the transmitter.

@MLE_online The only one I remember being decommissioned was the Mt. Bradley site way up in the north end of the state, because that moved to being part of a different repeater system. I think the ones near you should be working. If not you can sneak in via Echolink, K6LNK-R
