on dslreports or broadbandreports there's at least two instances of me complaining about two cable companies because, at last, it was figured out there was moisture ingress in the LE (line extender, usually on cable lines on poles). The only common denominator was it happened during prime time, every night, and went away around midnight. The other common denominator was the cable company refusing to believe it was an…

Interesting, I wonder if I’m experiencing something a little bit similar that Comcast can’t seem to debug. Almost every day, in the heat of summer, I get one to five 10-minute outages as soon as the temp gets over about 80F. More when it’s hotter, usually. Usually it results in a modem reset, so it’s hard to tell how long the actual outage is. Been happening for going on 5 years. They replaced the under-street cable…

Several day's of 80+ temps, meaning it hasn't dropped below 80? Possibly it is just getting above 80 before you start your work day. And not dropping below until after your work day has ended?

I've experienced something similar except for temperatures below ~32-36 degrees. At this particular location it would result in a ~1hr outage going below that temperature, but not when it went back above it for some reason.

https://en.wikipedia.org/wiki/DaSH_PA I don't know if Alec Proudfoot counts as a normy, but DaSH PA flew a bunch of times, with many different pilots. That particular event, which was an attempt to try some records, was a bust; there had been rain recently and the dry lake beds weren't. Landing gear was a recurring problem (light weight and robust don't go together), and even some last-minute attempts to build a runw…

That's really cool! I was only aware of the Gossamer Condor/Albatross and MIT's Daedalus in that field.

Nope, it's at the point that there's whole gatherings (most recently in the UK) where multiple aircraft and their builders/pilots/communities meet.

When I was a student of mechanical engineering many years ago I was very lucky to do an internship at a major car supplier in Japan. We did the engine application for a car on the Chinese market and being unexperienced as I was, I was more of a burden than help to the engineer who I was assigned to.

However, when driving around with our test car, from time to time the engine stalled, or stalled an restarted. This seemed to appear randomly, and since the engineer was busy with doing the engine application, he asked me if I could try to take care of the issue.

I noticed that the problem occured only during rain, then I noticed that it only occured when the windscreen wiper was set to interval. With some help from engineers from the main office, I was able to find the relais controlling the interval mode for the windscreen wiper as the root cause. I was sending voltage spikes into the cable tree, causing a reset in the central control unit. A decision was made to change the supplier for the relais (this was not supplied by our company), and the problem disappeared and never occured again. Everybody was happy and I felt really proud that I was actually able to contribute to the success of the project.

We had the same problem at an old house. There was a cable splitter in the attic that was expanding in the heat and losing connection to the cable. We bought a heftier one and moved it under the insulation in the attic.

This is a secondhand anecdote, but it’s pretty funny. Back in the days of server rooms, a friend’s server for his company would reboot every day around 5pm. They checked everything they possibly could with the OS, they would be logged in and running checks on it and it would spontaneously go offline for about 5 minutes and reboot every day. Finally they decided to go stand in the presence of the server around the tim…

this is why denmark has an additional slanted plug for IT equipment and a winky one for hospitals

How can, say, a cleaner tell the prong configuration on a plug when it's plugged in and not visible?

What industry?

manufacturing.

You don’t happen to be the guy who overnighted a bunch of network cables for $5,000 because the boss had to have them overnighted and the company didn’t care what it cost I read about recently? lol

This reminds me of a strange recurring experience I used to have with electronics in my house. In that house,on certain days of the week at midnight, something that sounded like recordings of political speeches from WW2 would be audibly (but faintly so) from all of stationary electronics. It was so faint, that it was usually hard to pinpoint any one source, and the words used weren't understandable, so it usually sou…

Near my work, there is a roughly 25 foot stretch of road in front of a factory where seemingly every FM station is overpowered by Muzak. I don’t know what the heck is going on in this factory but I have seriously considered contacting the FCC.

1999, the town hall of a small municipality s/e of Stuttgart Germany. For the 3rd time in half a year me (IT apprentice) and senior developer are onsite to fix one MS SQL db's broken indizes. It's the early afternoon of friday and humid hot, a thunderstorm is on it's way. We toil on and are almost done when at about 16:00 the chief officer turns up and informs us that we have to hurry because at 17:00 all electricity will be cut in the building! Senior developer and me share a shocked glance. "Is this every friday?" "Why yes! We conserve lots of energy that way." Senior and me share another glance and on impulse I speak up. "Isn't the weekly db cleanup scheduled for 16:30 PM on fridays?" The senior developer nods. We spend the remaining hour to fix the problem and then cancel this weeks schedule and manually shut down the DB server for the time being. Every friday these guys cut the power to the building, causing all kinds of production issues with not only their Netware Server but also the DB server for their collections software (our product). As per maintenance contract we were required to repair the DB everytime which was a hassle and a waste of ressources on our behalf. In the end it took another month or so until they relented and rescheduled the hard power down until saturday morning so that all servers could shut down properly even AFTER the backup jobs could complete (backup was also totally broken but they never did check or even perform a restore so they never actually noticed).

Ah, gather 'round, me dear friends, and let ol' Uncle Colm regale ye with a software engineering tale that'll have ye chucklin' and admirin' the wonders of technology!

'Twas back in the early days of the internet, when dial-up connections ruled the land and floppy disks were the height of data storage. I found meself workin' as a young software engineer for a company that aimed to revolutionize the way folks communicated. They called it "email."

Now, ye might think email's as commonplace as a pot of tea these days, but back then, it was like magic. Me team and I were tasked with creatin' the very first email client for personal computers. We had grand ideas, but, oh, the challenges we faced!

Our office was a chaotic mix of wires, half-eaten sandwiches, and programmers hunched over their keyboards, with cups of strong coffee never more than arm's reach away. We'd spend hours debuggin', tweakin', and scratchin' our heads, tryin' to make sense of the code.

But there was one particularly ornery bug that had us stumped. Every time a user sent an email, a gremlin in the system would gobble it up, and it never reached the recipient. We dubbed this foul creature the "Email Bandit."

We tried every trick in the book, but the Email Bandit remained elusive. The boss was near despair, and me colleagues were ready to throw in the towel. But ye see, I had a plan. A plan so bold, it was downright cheeky.

I reckoned that if the Email Bandit was stealin' our precious messages, maybe he had a hankerin' for a particular type of email. So, I composed a message that read, "Dear Email Bandit, we've got a special treat for you. Please don't eat this one."

We sent that message out into the digital wilds, and we waited. Lo and behold, within minutes, the Email Bandit struck! He gobbled up the message and vanished into the ether.

Now, remember, we engineers are a clever bunch. We'd embedded a little tracker in that email, and it led us straight to the Email Bandit's hideout – a rogue line of code that no one had noticed before.

With the Bandit cornered, we rewrote that line, patched up our software, and celebrated like we'd won the lottery. From that day on, our email client worked like a charm, and we'd slain the Email Bandit once and for all.

So, me friends, never underestimate the power of a bit of creativity and a dash of cheekiness when it comes to solvin' software engineering conundrums. And remember the tale of the Email Bandit, a reminder that sometimes, the most elusive problems have the simplest solutions, hidden in plain sight. Sláinte to the world of software engineering!
