Ha. The search page is working again. So only the status page seems to be down.


And requires me to remember to get up and hang it before a scheduled meeting. Or not hang it when someone calls me and a meeting erupts. And I need to remember to take it down after each call. (If I don’t, then it’s just up all the time and might be taken as seriously as a Prop 65 Warning.)

Automations are really nice for certain things!


And I'm sure you've set up all the systems that make sure the complicated system is actually working and not dead weight or doing something unintended.

> Versus, I dunno a door lock

They just explained why a door lock has absolutely abysmal reliability.

"Making sure" the complicated system works significantly better than a door lock is actually really easy to do, because the door lock is so bad.


sir, this is hacker news


obviously you need a remote motor that spins the sign to "do not disturb" when the meeting starts and then back around when it's over. and a sensor to verify it's in the correct orientation.

so you get the simplicity of the sign with the automation desired by the OP.


A webcam in the corridor that shows your office door from the outside, machine vision reads the image to know which orientation the sign is in. If a meeting begins and the sign is wrong, a little LED on the desk starts flashing red.


An alternative would be to spin the sign constantly around its center of mass while a meeting is in progress.


The meeting state coheres when the sign is observed.


nice! a clear application of quantum computing if i've ever heard one!


I dreamed of having one of these when I was in high school drafting class!

They definitely were worth it over “acoustic” erasers, but cost something like $70. The few times I got to use one spoiled me.


My brother and I bought the same album back in 1994. Stone Temple Pilots—Purple.

I had it on CD, he bought the tape.

The CD sounded (obviously) so much better than his tape. But a little while later I made my own tape copy of the CD, and my copy sounded really close to the CD! Way better than his store-bought copy.

Those bastards didn't even have the decency to use Type II cassettes for the released album.

A Type II (or even better, Type IV-Metal) tape could sound pretty damn good. Still sucked to have to rewind or fast-forward, though.

(Also, Dolby NR was terrible. I'd rather have the hiss than have the muted highs)


Don't forget about quality loss from manufactured cassettes being high speed dubs. There's significant quality loss as you increase the dub speed.


Yeah mass-produced tapes were pretty bad but if you copied an album to cassette using a good tape and decent tape deck they could sound pretty good. Good enough for a Walkman or playing in the car anyway.


Pioneer, metal tape (TDK) and Dolby, man.


Maxell man!!! j/k

even the tape hiss in the ad about a cassette tape is golden


One of the all-time great iconic ads. The photo of the guy in the chair was available as a poster and graced many a young man's bedroom or dorm room wall.


I still have cassette tapes encoded with dbx rather than Dolby and the former's sound quality is much better than the latter. I'd recorded them on Technics decks, which is why I still keep an old deck of that brand for playback and ripping as the bias values are identical.


All the best things in this world aren't covered by insurance :)


What would be an appropriate suppression system here? That's a lotta batteries all arranged like a boy scout arranges kindling logs for a campfire.

A roof-mounted water tank with a thousand gallons ready to dump into the shed? A drum of baking soda?

Or maybe rebuild the shed out of cinder block and clear any overhanging vegetation?

Maybe this whole setup is on desert dirt with plenty of clearance. The fire plan is "run away and wait."


A ton of sand, but that's the main issue with those systems and why it's genuinely impractical as anything but a hobbyist project. They need constant monitoring as all of those cells are from laptop and risk thermal runaway at some point. Even with the best matching possible some cell in his configuration will have higher internal resistance and create heat. "Real" large off-grid systems all use LiFePO4 and are unlikely to just catch fire. That being said from the forum post he seems well aware and he probably has individual fuse for each cell.

You could also just bury it so that the worst of the explosion is mostly mitigated. I've also seen small container setup which would probably work better than his (seemingly) wooden shed.


I wonder if the correct solution here is build the shed far away from house and trees, on a cinderblock foundation filled in the middle with 8+ inches of sand, and you just stand back with the garden hose to keep everything around it moist.


You can see the shelter here [0] and it is apparently 50m from the house [1].

Would be better if the ground was paved around the shed, but it seems to be far enough from other free standing structures.

VMs are too resource hungry.

No, the many-worlds interpretation shows that our universes are merely containers with copy-on-write behavior :)


Yeah, could be a giant LMDB, but that's implementation detail :)

I imagine there's some serious optimization involved to make it all fit in memory.


Wikipedia has good info on how RespOrgs handle this:

The fictional block exists, but it's not the entire 555 prefix. It's 555-01xx.

It was the entire "Klondike-5" block, but got narrowed.


If you place a device with a high-gain directional receiver pointed toward the fob, and a high-power transmitter pointed toward the car, wouldn’t that work?
