Too Spicy For My Hat

by in Error'd on

My plate has been full this week, but not as full as Walter's!

"Maybe hold the cheese?" suggests Walter T. regarding a pepper and steak grinder. "Seen at Reading (MA) House of Pizza on Jul 24 2024." If you decide to search around to try to understand the different names for this kind of sandwich, you will undoubtedly discover someone trying to claim that really, the hoagie is a different sandwich from a submarine, which is different from a grinder and so on. They are wrong, and this is how we know: if they truly were different kinds of sandwiches, then somewhere on this planet would be a shop selling examples of each of the different variants for your dining pleasure. There is not*. Q.E.D any consistent regional variation in bread choice, or dressing, or fillings, is simply that: a regional variation of the same thing, not an entirely different category.
*Until someone can show me the existence of such a sandwich shop, I assert that it does not exist, thus my proof holds.

Adrian M. lit up this blooper for us. "Apparently Siemens Mobility wasn't satisfied that a mere 95-year copyright term would be enough for the brochure about their m60-series traffic light controller. I hope I won't have to wait until 2029 for a green light." See for yourself here.


Watching the Days

This week, we saw some unexpected results in UK politics. Nothing was more unexpected than the dark-horse results that Richard and a few anonymice remarked on.

"A glorious victory for the Undefined party!" crowed Richard "The UK general election has seen a surge of support for minor parties."


That Movie with Whatsisname

by in Error'd on

This week's special edition is a series of Error'ds specifically dealing with trains, which geeks are for some reason especially taken with. It should go without saying that the reason these are predominantly from Europe is not an indication their infosystems are especially bad, but rather as we all know, US passenger trains are so little used that there is far less opportunity to discover any wtfs.

This entry by Robert G. requires explanation. London North East Rail has a novel (six years old now but still new to me) point-of-use display of seat reservations. In my train experience, a reserved seat ticket only identifies a certain car but not a specific seat, so this is pretty slick. On LNER, if you don't have a seat reservation but you're traveling in the specified class, you can take any seat labelled "Available" but you'll need to vacate it at the "until XXX" station. The two rows in Robert's fuzzy image read "Current" and "Next", which should help to understand what has happened here. The two red lights indicate "Reservations". As Robert puts it, "My train was part cancelled, and a replacement coach was provided to where it was now starting from. Unfortunatly the coach arrived a few minutes after the train departed, so a new train was needed. Fortunatly the TOC's (Train Operating Company) app allows seat reservations to made up to 10 minutes from departure and the next train was in half an hour - given it's a long journey I was going to get a reservation. Apparently several other people had the same idea, resulting in two of us getting a confirmation (both email and in app) for the same seat." Apparently Robert reserved Edinburgh->KingsX and a random competitor reserved Newcastle->KingsX at the same time. It seems that LNER's seat reservation application had a failure of transactional integrity. Hopefully it was eventually consistent.
