  • That analogy was chosen for a reason. Ada was originally developed by DOD committee and a French programming team to be a programming language for Defense projects between 1977 and 1983 that they were still using at least into the early 2000s. It’s based on Pascal.

    It was intended for applications where reliability was the highest priority (above things like performance or ease of use) and one of the consequences of that is that there are no warnings - only compiler errors, and a lot of common bad practices that will be allowed to fly or maybe at worst generate a warning in other languages will themselves generate compiler errors. Do it right or don’t bother trying. No implicit typecasting, even something like 1 + 0.5 where it’s obvious what is intended is a compiler error because you are trying to add an integer to a real without explicitly converting either - you’re in extremely strongly-typed country here.

    Libraries are split across two files, one is essentially the interfaces for the library and the other is it’s implementation (not that weird, and not that different than C/C++ header files though the code looks closer to Pascal interface and implementation sections put in separate files). The intent at the time being that different teams or different subcontractors might be building each module and by establishing a fixed interface up front and spelling out in great detail in documentation what each piece of that interface is supposed to do the actual implementation could be done separately and hypothetically have a predictable result.





  • This might seem nit picky but the scientific method as we know it today require that peer review and require methods of reproduction. Whether you can reproduce results is a different story.

    Oooh, are we about to have a discussion on whether large portions of the soft sciences across the past several decades fail to be “real” science due to the reproducibility crisis?

    I find it especially amusing that in my Lemmy feed the post right before this one is a quote from a book by a Nobel laureate talking about the importance of self-marketing, politicking and ladder climbing in academia. You know, all the stuff that isn’t science that plays a part in what Yann LeCun considers to play a vital role in what counts as science.

    H1B skilled worker visas. You have to prove that you tried to hire locally and couldn’t find anyone qualified. The whole point is that the qualifications are impossible, so you are either under qualified or lying. Since no qualified candidate exists, you can bring someone over from overseas and hold the risk of being deported if you fire them over their heads - and you suddenly get less thorough about checking qualifications for your immigrant candidates.


  • (And/Or with a fine that required us to do more than lift up our couch cushions.)

    That’s a problem with the amount of fine being set by law and despite likely not being as wealthy as claimed, Trump still has enough money that $10k isn’t going to hurt him.

    Jailing him for contempt has all the same logistical problems imprisoning him is going to, but at a smaller, less secure facility.

    Someone should look up the maximum sentence for what he’s been charged with. The current biggest hold-ups are not being able to make someone appear in multiple trials in different places simultaneously, and avoiding the appearance that the court is trying to interfere with an election.

    You don’t want the court to not care about the appearance of interfering with elections, or else you’ll have the GoP trying to get Democrat politicians on dubious charges that they’ll definitely not be guilty of but will definitely bury them in scandal and prevent them from campaigning effectively.


  • As the size of the pyramid increases the obvious algorithm (walking all the routes down the tree) is going to fall afoul of the time limit pretty quickly, as are several alternative algorithms you might try. So a pyramid 100 or 1000 levels deep very rapidly falls out of the time limit unless you choose the right algorithm because there are 2^(n-1) paths for a n-level pyramid. I’d suggested a…much bigger dataset as one of the judgement datasets One that took my reference implementation about 15 seconds.

    This was a contest for high school kids c. 2001 and was going to involve 4 problems across 6 hours. The prof making the decision thought it was a bit much for them to figure out why the algorithm they were likely to try wasn’t working in time (noting that the only feedback they were going to get was along the lines of “failed for time on judgement dataset 3 with 10000 layers”, that it was because it was a poor choice of algorithm rather than some issue in their implementation, and then to devise a faster algorithm and implement and debug that all ideally within 1.5 hours.

    For example, the algorithm I used for my reference solution started one layer above the bottom of the pyramid, checked the current number against either child it could be summed with, replaced the current number with the larger sum and continued in that fashion up the pyramid layer by layer. So, comparison, add, store for each number in the pyramid above the bottom layer. When you process the number at the top of the pyramid, that’s the final result. It’s simple and it’s fast. But it requires looking at the problem upside down, which is admittedly a useful skill.




  • See, when I was a comp sci undergrad 20-odd years ago our department wanted to do a programming competition for the local high schools. We set some ground rules that were similar to ACS programming competition rules, but a bit more lax - the big ones were that it had to run in command line, it had to take the problem dataset filename as the first parameter and it had to be able to solve all datasets attempted by the judges in less that 2 minutes per dataset, noting that the judgement datasets would be larger than example ones.

    Some of the students were asked to come up with problem ideas. I was told mine was unfair, but mine was entirely about choosing the right algorithm for the job.

    It went like this - the file would contain a pyramid of numbers. You were supposed to think of each number as connecting to the two numbers diagonally below it and all paths could only proceed down. The goal was to calculate the largest sum of any possible path down.



  • Wouldn’t matter, because the problem isn’t about space or motion, but about position. If you jump backwards in time but your position in the universe doesn’t change then you are probably no longer on earth because the Earth moves about the sun, etc. To land somewhere meaningful, you’d have to calculate the target location relative to some reference point with a predictable location and as Earthlings we’d probably pick the Earth itself unless this is a time traveling spacecraft.


  • I actually had someone whose family member died of Covid tell me that his brother-in-law didn’t really die of Covid, he died of something else, because it’s all overblown and the hospitals are doing a similar scam to this myth (i.e. making it out as a bigger deal than it needs to be.)

    That sort of thing goes around here a lot too, usually framed in terms of “He didn’t die of COVID, but if you die from any cause whatsoever while you also have COVID they’ll count it as dying of COVID to make the COVID numbers bigger.” It usually falls apart when you ask why they want the COVID numbers to be bigger than they really are.



  • That’s exactly what I was thinking. I’m totally fine with about half of the directions given, and the rest are baking in right wing talking points.

    It must be confusing to be told to be unbiased, but also to adopt specific biases like that. Also, I find it amusing to tell it not to repeat any part of the prompt under any circumstances but also to tell it specifically what to say under certain circumstances, which would require repeating that part of the prompt.


  • Media presents time travel as just inputting the date and off you go, but really you need to input time AND space because the two are interconnected.

    Alternately since we’re Earthlings, someone designing a time machine might think it’s a good idea to automatically calculate the location using the Earth as a reference point because that’s likely to be the most common use case and doing so would prevent you from dying to the void of space if you make a tiny math error. At which point you would just need to input the destination time if the target is the same location relative to Earth.
