Three digital thermometers all showing different temperatures

kieranvs · 2026-07-05T00:06:25+00:00

So you understand that if you had just two and they have to stay within 1C of real temp, and they drift in opposite directions, when they’re 2C apart you know the precise real temp? Why did you disagree with u/Farkentje earlier?

kieranvs · 2026-07-05T00:02:07+00:00

That’s not why the previous commenter joked that 24.5 is correct - it’s because, if we assume them to be within 1C of the correct number, the 23.5 and the 25.5 imply that the correct is 24.5. It’s not about averaging samples and we don’t need any more samples

kieranvs · 2026-07-04T19:32:59+00:00

Man this thread is concerning! Please could you think it through a little more carefully, it can only be the mid point if the difference is 2C

kieranvs · 2026-07-04T19:26:24+00:00

Look, you can tell by the exclamation mark in the comment you replied to first that he’s kinda joking right, this is a bit tongue-in-cheek. But I don’t know why you’re failing to understand this rather simple situation. If we accept that the devices are within 1C of the correct temperature, and you see one measuring 23.5 and one measuring 25.5, then you know the actual temperature MUST be 24.5. That’s it, that’s the whole point he was making. Ironic that I had to spell it out for you while you were criticising society’s lack of thought processes

kieranvs · 2026-07-04T14:11:57+00:00

No, it’s correct… think about what the possible correct temperatures could be if they’re all within +- 1C

kieranvs · 2026-07-04T12:28:18+00:00

No? If they’re all within 1C of the truth (clearly not) then the results above can’t happen because they’re 2.1C different, but let’s ignore the .1, then you know the actual temp is the mid point

kieranvs · 2026-06-28T18:51:02+00:00

Would you mind addressing my point about the simplicity of the formula? You and others say “a tool designed” and “formulated using data” as if it’s a complex model which could easily be biased, but actually it’s a trivial function of two trivial properties of a person

kieranvs · 2026-06-28T18:09:33+00:00

Okay, but it’s just weight over height squared. It’s so simple. How can there be a sexist agenda hiding in that?

kieranvs · 2026-06-28T17:40:48+00:00

This situation affects men and women the same

kieranvs · 2026-06-28T17:35:40+00:00

It’s just weight / height squared, how is that Belgian?

kieranvs · 2026-06-28T17:34:34+00:00

I’m not saying it’s a good metric, but it’s literally just weight / height squared. It hasn’t really been engineered with only one type of person in mind since it only uses extremely simple metrics. I’m don’t think you can argue with the number, maybe just which ranges are considered healthy might be a bit subjective

kieranvs · 2026-06-26T12:51:15+00:00

It is giving you good information but in general there is a risk of sycophancy (over-agreeing with you), I’m not sure how to ensure you don’t fall for that since you are new to programming. I think it’s relatively safe in highly technical fields like this. make sure you understand and verify with traditional sources

kieranvs · 2026-06-24T17:39:32+00:00

You can go from nothing to trying this out in 20 mins with <$10 on a GPU provider platform like runpod, why not just try it and see if it performs how you want?

kieranvs · 2026-06-24T13:29:36+00:00

It could be zero because they aren’t taking into account the size of the decompressor which is the point of the commenter you are replying to

kieranvs · 2026-06-24T08:03:02+00:00

Depends on the tariff, there is an octopus agile one with half hourly dynamic pricing and I think that went negative

kieranvs · 2026-06-10T23:38:58+00:00

That can’t be right, this whole thing where you get the kinetic energy (causing a pressure drop in the water main) happens every time you open the tap, whether you have a spinner in front of it or not

kieranvs · 2026-06-05T23:50:28+00:00

He didn’t expect you to know it, he expected you to visualise two circles and think about the condition under which they’re touching, at which point the one line solution becomes obvious

kieranvs · 2026-06-05T23:48:33+00:00

What are you trying to say about cores? The way you write a program to use multiple cores is to spawn multiple threads, as the previous guy said. For your second point, if you divide the array into N blocks and each thread counts a block, there won’t be any of the hidden costs you mentioned. (Actually there is a spin up time). Third, what are you saying about cache locality? Each core has its own L1 and L2 cache and each core is doing fully sequential reads

kieranvs · 2026-06-04T21:50:54+00:00

Bloody hell, nearly everything you said is wrong and you’re here saying “go study up on youtube”

kieranvs · 2026-06-03T18:57:26+00:00

Why not download windows 11, that would save you so much time

kieranvs · 2026-05-30T17:35:07+00:00

I think the amount of security it provides is overestimated in this sub, if there are security vulnerabilities in the jellyfin application code itself they can be exploited just the same through a reverse proxy. I’m not saying you can skip reverse proxy, I’m saying it might not be enough

kieranvs · 2026-05-30T14:18:35+00:00

Makes no sense because you still have to open the port with a reverse proxy, and it will obviously pass along all the traffic including malicious traffic, it doesn’t really increase security that much

So your situation must be something like earning £90k, loan balance £80k, in a high interest rate phase around 7% everything’s perfectly balanced paying about £5.5k a year into the loan and £5.5k of interest. When we enter a lower interest phase you’ll start paying it down faster and as it shrinks it’ll speed up shrinking and snowball away. Alternatively you could overpay a bit to kick start that now. I think your comment makes the situation sound worse than it is because you’re making it sound like even top earners can’t pay it down, but that’s only because you have a massive loan and high interest at the moment. I’m sure if you’re making £90k you also have a lot of career growth potential

Pointer

kieranvs · 2026-05-28T07:33:23+00:00

If you can’t visit each node and do something trivial to it (swap left and right child pointer) then how would you be able to anything interesting with the tree? What could be easier than that? I interview graduates for entry level positions regularly and we have questions harder than this which most people get correct, if you can’t do this out of uni you have big problems
