Time to revisit the 500 miles email... http://web.mit.edu/jemorris/humor/500-miles

Funny how he went about troubleshooting. I guess it was a long time ago and they didn't enable logs to save disk space.

Because me being a sysadmin for the past 14 years would go directly to the logs and see my client timing out.

Reminds me of "story of a car that wouldn’t start every time its owner bought vanilla ice cream". http://www.kepner-tregoe.com/blog/help-my-car-is-allergic-to...

Please, somebody, create a website that centralizes all these weird bugs! Could be a very good resource to "debug things", try and approach problems with different approaches.

Is it just me who'd love something like this to happen to me? Would be great fun tracking down the source of the problem (if it was my car; probably less so if I was in the house...) There's a lot of options to try to isolate the problem, just thinking out loud here - a) Back into the driveway returning from work. See if alarm goes off. Next morning, see if alarm goes off as you drive out. b) Remove fuse for reverse…

I had to debug my home this summer and I think it makes a good story. I have been renting this appartment on the ground floor for one year, and for environmental and economical reasons, I decided to try to reduce my electricity bill, which was quite large for the size of the appartment. An obvious culprit was the Canadian winter in a poorly isolated place, but I was also wondering about why in summer I had around 22-…

So what's the other story??

Along the same lines, I had a hell of a time tracking down the reason my washroom GFI (ground fault interrupter) tripped on random occasions; i.e., the electric outlet would lose power and need to be reset. It turned out that an iPhone receiving a phone call tripped it -- even before it starts to ring! Making a phone call didn't do anything. Here's a 13-second video: https://vimeo.com/247730625 I'd love to hear comme…

The timing sounds like RF interference. I worked in TV a while back, and we were not allowed to have any cell phones (even silenced) on set - they would introduce this crackling sound into lightly-shielded cables near them. The interference would kick in about a second or two before the ringing started, because there's probably some handshake/setup before the receiving phone decides it's actually an incoming call. In…

I do the same thing in recording studios. You have to turn off your phone completely. Nothing worse than ruining a good take when you receive a call.

I've heard stories of unplugged loudspeakers turning into AM radios with enough power pumped into the air, so there's that too.

AM radio has all kinds of "fun" properties. https://www.youtube.com/watch?v=GHSuInSkHtA Listening to the tranmission using the arc the tower generates to ground!

Holy %!#@! That is one of the most interesting things I've ever seen.

Why would someone microwave blueberries?

Making sauce or heating up a muffin, I guess? Or frozen blueberries, but why would anyone buy frozen blueberries.

why would anyone buy frozen blueberries

Because 'fresh' blueberries out of seasons cost 3 times as much and taste like nothing much.

It's a bit more serious, but good old RISKS DIGEST is worth a read for this kind of thing. https://catless.ncl.ac.uk/Risks/

I can often tell that I'm about to receive a text message because my poorly shielded computer speakers will start buzzing. I assume it's caused by a transmission from my phone's radio inducing a current in the amplification circuit. I would guess this is what's happening with your GFI. Even though you're receiving the call, your phone is probably transmitting too (sending back the equivalent of an ACK or something).…

I remember old feature phones which had a fancy light on the back, which started blinking whenever a call was about to come through. Was a pretty nifty feature when you were expecting calls ['twas a time when I used to give "missed calls" for a callback].

We had a fire alarm going off due to low battery once. We searched the house for 3 hours trying to find it. Gave up, slept through the beeping. Next day, enraged, we tried again. Eventually we found it in the bathroom trash can.

Just did this yesterday, and eventually found it was the neighbours one that was flat. It’s the 3rd time I’ve knocked on a neighbours door (different people each time) to ask them to take a battery out an alarm. I’d consider it a feature if they combusted after alarming for a day.

I am Deaf. In the night you would need to break into my flat, too, because the flash indicating the door bell is in the living room, not the bed room. Nobody and nothing disturbs my sacred nightly sleep.
