Every year when we move the clocks forward there's a large spike in fatal car crashes and heart attacks. These are not small effects.

ultrafilter posted:Every year when we move the clocks forward there's a large spike in fatal car crashes and heart attacks. These are not small effects. So let's talk about calculations for oncology software, which a friend of mine who definitely isn't me has worked on in the past. The way a PET scan works is that the patient is injected with a radioactive isotype that binds with glucose - this highlights metabolic activity on the scan. In order to interpret the scan, the units are normalized into what is known as "SUV", or standard uptake value, which is a unit of density on the image. So given a pixel value on the image, you can empirically say "hey, the suv value on the pixels in this tumor in this roi is high, this could be cancer." Unfortunately, one of the variables that goes into this calculation is "injected activity" - and the problem is that the software (depending on the scanner) may need to decay correct this value (as since the isotype decays, the amount of radiation being emitted will go down over time) - and decay correction involves finding the time difference between when the isotype was injected, and when the scan started.  These times are all stored in the dicom header as metainformation. Here's the https://qibawiki.rsna.org/images/8/86/SUV_vendorneutral_pseudocode_20180626_DAC.pdf for calculating the SUV value. A recent topic of research has been the inexplicable variability in these measurements, e.g. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5698613/ https://www.ajronline.org/doi/pdfplus/10.2214/AJR.10.4923 So like... hypothetically, say whether or not a tumor is considered as cancer or not changes depending on whether or not your scan gets done at midnight, or when the clocks change over to DST That'd probably be undesirable, right?

This is great, saving this. Went looking for the Hartford coliseum disaster, found this list instead 20 famous software disasters Some engineering journal posted:This roof was noted for being one of the first large-span roofs made possible by computer design and analysis, and was modeled as a space truss using a trusted program. The roof of this three-year-old structure collapsed at 4:15 AM on January 18, 1978 during a freezing rainstorm after a period of snow. Fortunately, there were no injuries sustained as a result of the collapse. The night before, there were over 5,000 people in the coliseum attending an event. Following several investigations of the collapse, it was determined that this was an instance primarily of inadequate structural design.

NtotheTC posted:https://www.theverge.com/2021/4/23/22399721/uk-post-office-software-bug-criminal-convictions-overturned That story has been running for decades. It would be interesting to know more about the software issues that led to the accounting being off by tens of thousands of pounds - I've never seen any detail on that. But everything I've seen about it suggests that it was primarily a problem in the management culture of the Post Office, and the actual software bugs are probably not that interesting in comparison. They didn't believe or didn't want to believe that their lovely software system might be giving them the wrong numbers, and they were happy to crush the little people and get them sent to prison rather than investigate whether anything was really wrong with their system even though there were dozens of cases all being prosecuted at the same time

It wouldn't be surprising if any of the people responsible for pushing through the prosecutions got off with no consequences.

I'd love to know the Fujitsu side of the story, did they just chuck it over the fence and say it's done, no more support? If the Post Office management made a ruling early on that it must be theft and never even passed it on to Fujitsu then that's one thing but surely they heard about this over the 3 decades or whatever. Also, "Earlier this month the chief executive of the Post Office said that Horizon would be replaced with a new, cloud-based solution." just incase someone thought a lesson had been learned.

People who aren't computer programmers by trade generally make the assumption that computers are good at stuff like multiplying or adding two numbers together, especially if they grew up using electronic calculators. Floating point is actually such ridiculous bullshit that it takes experience to realize how easy it is to gently caress up with it.

It's worth pointing out that this "horizon" system has been in place for a long time, by the standards of computer systems (well, maybe not by the standards of government computing systems). Like I said in my previous post, this has been a story for decades. The system was introduced in 2000. It's not that remarkable that they might have decided to replace a 20-year-old system.

The UK has plenty of really bad poo poo in its history, even if we want to restrict it to relatively recent events and not go back to Cromwell or whatever. This is very bad but doesn't even come close to "largest miscarriage of justice" in the UK. For instance, in Northern Ireland in the 1970s, civilians suspected of IRA involvement were captured and extrajudicially tortured, and a military unit opened fire on an unarmed crowd. The investigations were, of course, totally whitewashed. And of course that's just within the UK proper, not even getting into the prison camps, torture, and summary executions that were official policy during events like the Malayan Emergency or Mau Mau uprising.

I don't know what is happening in your head, you have to tell me. That's all I wanted to get across.

Not So Fast posted:"miscarriage of justice" specifically refers to court cases getting overturned, not just all the war crimes we've done over the last few centuries I guess I also interpreted "miscarriage of justice" much more narrowly than Space Gopher in particular. To me it doesn't merely mean "unjust thing that happened", rather it means a case where a court convicted somebody when they shouldn't have. So while the things they mentioned were unjust, not all of them are "miscarriages of justice" as such... to me. But I didn't want to drag things off on a tangent about what exactly qualifies as a "miscarriage of justice", or try to impose my version of what the term should mean. My real issue is that I've a pet peeve about the way goons communicate. Oh yes, and a Creme Egg McFlurry please.

Most of the reporting I've seen about it refers to it as the "most widespread miscarriage of justice" presumably meaning as opposed to one corrupt region, it has affected the whole of the UK. The quoted article says "reportedly the largest miscarriage of justice" which seems like The Verge misinterpreting the other sources since in terms of number of cases overturned, it's not actually the largest. Nowhere have I seen anyone refer to it as the "worst miscarriage of justice".

I believe I've made my feelings clear regarding how the post might or might not be interpreted, so I won't respond to further posts expressing simple disagreement with my interpretation (or refusal to interpret). That'd just end up being a sequence of "nuh uh" "uh huh" posts and it's not worthwhile. By all means continue disagreeing and call me dumb or w/e, I've made my views a matter of public record at this point.

It doesn't matter whether or not they had something specific in mind. You're not refusing to interpret the post; you're reading a specific interpretation into it, realizing that the interpretation you came up with made the post ambiguous, and then complaining about the post rather than re-evaluating your reading of the post.

As penance for derailing the thread, have a story about what I'm doing with my time this past week or so. When I joined this company a few years ago, everything was on Perforce. Now in 2021 nearly all development activities are on Azure DevOps. My team is the last one left using Perforce on a day to day basis and I'm working on changing that by moving us over. I have some scripts that use "git p4 clone" to reproducibly create git repos for the various projects that live in Perforce. And I'm working on getting automated builds to run in the "new world". Things I've had to gently caress around with in the last couple of days:
