> Can't log in when standing up This reminds me of a recent issue I had. I had just gotten a new laptop from IT. While picking it up from them, I had generated myself a password, put it in my password manager on my phone, and then entered it twice to set it on the laptop. Everything worked great. But when I got back to my desk, the password didn't work! I tried a bunch of times, watched myself hit each key to elimina…

It's worth noting that sometimes (incorrect) keyboard maps can get in the way. If it's a key that you may not often type and one that is often transposed between regions, the fact that the entered char is not shown can lead to frustration. e.g. " and @ are in different positions in UK vs. US keyboards. So user thinks they are typing @, but " goes into the box.

No, that is why passwords are alphanumerical, keep your #€{*\$<€$<¥]+]!,’ to yourself.

I've collected a list of fun stories of this form and post them when this comes up: - Car allergic to vanilla ice cream: https://www.cs.cmu.edu/~wkw/humour/carproblems.txt - Can't log in when standing up: https://www.reddit.com/r/talesfromtechsupport/comments/3v52p... - OpenOffice won't print on Tuesdays: https://bugs.launchpad.net/ubuntu/+source/cupsys/+bug/255161...

You can add this one to the list: https://old.reddit.com/r/pcmasterrace/comments/7p09ay/i_shit...

If you strum an electric guitar and let the hertz of the string fall through the range of AM radio the amp will briefly pickup AM radio stations. Not that you can decipher anything but you recognize voices as it travels past the station.

That's not because of the frequency of the guitar but because the guitar functions as a very nice antenna (long piece of metal (the strong) + a coil forming a tuned circuit), what happens is that your hands create a very temporary partial diode where you touch the strings! Such naturally occurring diodes are an interesting phenomenon (in this case: the salt in your sweat interacting with the steel of the strings) and…

Too late to edit: strong => strings. sorry!

That may be one explanation, but more broadly with analog audio it is actually quite difficult NOT to end up with an AM receiver.

Wifi routers are little magic devices that work only when they want. I talked before here, but I had a Dell Vostro notebook that everytime it connected with my router using windows it would just kill the entire home wifi. It was a TP-Link mesh network. The only thing that would bring the thing up was to reboot every single router in the network and not connect that notebook.

I tried update my routers, tried to update my notebook wifi firmware, tryed to change the router config, the router position, the router order, the wifi channel, the wifi name and password. Nothing worked. But if I connected using linux, things would work just fine.

In the end I divorced my wife and brought a Thinkpad. She keeped the cat, the house, the routers and that dell vostro notebook.

I keeped the dog and the car.

Hehe. That's a very good point.

Of course, if you want to build a proper AM receiver you will find that it is quite hard ;)

Same with oscillators and amplifiers. You always get the other one first.

Oh, and it is also very hard not to build a microphone. Except...

>With a bit of work, my dad set up a line-of-sight Wi-Fi bridge — a couple of high-gain directional Wi-Fi antennas pointed at each other — between the office and our apartment. How was that not the first thing to be checked ? OP must have hit themselves over the head for not thinking of that one sooner

> How was that not the first thing to be checked ?

I'm a very technical person, and would be considered "smart". A few weeks ago, the TV remote was acting up. I changed the batteries, still happening. Restart the TV, still happening. The mobile app is working fine, I'm wondering if there's a fault on the IR blaster. Use a camera to check the IR blaster on the remote, seems fine. Factory reset the TV, still happening. Take the TV off the unit, pull out back of the TV off, solder to IR blaster looks ok. Put it all back together, still happening. Phone samsung, and go to make a coffee while I'm on hold. Come back, it's working while I'm on hold. Total time, 4 hours at this point.

Turns out, I had put a coffee cup in front of the receiver that morning, and unluckily put it back when I lifted the TV down from the stand...

Yup, pretty much any nonlinearity will demodulate AM.
