The top comment categorized scraping as abuse ("abuse such as [...] scraping") - that's precisely why some accuse its author of lack of self awareness.

Perhaps LLMs have mimicked the style because authors have popularized it and clearly it serves some benefit to readers.

Shouldn't the code say:

    position = (position + direction + 1) % 12;

Or have I misunderstood something?

How would that help? This doesn't seem like a solution to the CSRF problem

As a childless OMSCS graduate, I also can’t imagine doing it while having kids, because it took basically all of my free time. That said, I met quite a few people in the program who were in situations similar to yours. I have no idea how they managed it, but they somehow did.

> In that case the winning strategy would be to switch hedge funds every 3 years.

When you flip a coin, you can easily get all heads for the first 2-4 flips, but over time it will average out to about 50% heads. It doesn’t follow from this that the winning strategy is to change the coin every 3 flips.

Okay? I specifically responded to your comment that the parent comment implied "if you make a mistake and say sorry you are also a psychopath", which clearly wasn’t the case. I don’t get what your response has to do with that.

I think the point of comparison (whether I agree with it or not) is someone (or something) that is unable to feel remorse saying “I’m sorry” because they recognize that’s what you’re supposed to do in that situation, regardless of their internal feelings. That doesn’t mean everyone who says “sorry” is a psychopath.

New comment by ludwik in "Report: Tim Cook could step down as Apple CEO 'as soon as next year'"

But this sounds like an ideal setup, doesn't it? Tim is fantastic at execution, but he does need a shot of big-picture vision every now and then. Tim as CEO with Steve as Chairman, steering the broader direction, feels like it could have been a perfect pairing. The issue with how things actually turned out is that Tim ended up on his own - all execution, no vision.

Good call. I would feel extremely weird seeing "[my full name] is still alive" as a title somewhere...

I think you misunderstood what people are taking issue with. You explain that this matter is complicated and non-trivial - and yes, that’s exactly the point!

People don’t have a problem with real-time communication via audio or video in general. They have a problem with the suggestion that it’s a trivial issue that can be easily fixed by "jumping on a quick call."

The point about there being a "fairly in-depth" description of the issues isn’t that there’s nothing more to discuss - fixing those issues would obviously require talking through the specifics. The point is that this is a real problem that requires action and commitment, so suggesting it’s a non-issue that can be clarified with “a quick call” comes off as dismissive and unproductive, whether that’s intentional or not.

There is a big leap between them not being the sole person responsible for technical decisions and them not even necessarily having a seat at the table for technology direction. The former is understandable. Later - quite surprising.

That’s like saying Volodymyr Zelenskyy supports Trump. Foreign politicians operate outside of U.S. domestic politics - they don’t get to choose other countries’ leaders. Their job is to use diplomacy to navigate international politics in whatever shape those politics happen to be in.

New comment by ludwik in "One person was able to claim 20M IPs"

ludwik — Sat, 16 Aug 2025 20:07:51 +0000

20 million unique users is not that much. I don't understand the claim that this constitutes 9% of all IP addresses. It doesn't. There are about 4 billion public IPv4 address. 9% of that would be closer to 300 million.

New comment by ludwik in "AI is different"

ludwik — Sat, 16 Aug 2025 19:48:33 +0000

I don’t see a claim that anyone with a negative attitude toward AI shouldn’t be listened to because it automatically means that they formed their opinion on older models. The claim was simply that there’s a large cohort of people who undervalue the capabilities of language models because they formed their views while evaluating earlier versions.

Turns out what constitutes "claiming" an IP on the site is nothing like you’d expect. You don’t need to prove you control the IP. All it takes is embedding a transparent 1x1 tracking pixel on a website, and every IP that loads the page gets counted as “claimed” by you. In other words, it’s just a tally of visitors (or even ad impressions), not actual control of the IPs. So there’s really nothing meaningful here.

Why train the model to know how to use very specific tools which can change and are very specific only to ChatGPT (the website)? The model itself is used in many other, vastly different contexts.

It is used here as the default for cases when the user doesn't know or care about the technological details and is only interested in the end result. It is preferred because it integrates well with the built-in preview tool.

There is "performance" as in "speed and cost" and performance as in "the model returning quality responses, without getting lost in the weeds". Caching only helps with the former.

No, it's because that's what ChatGPT users internally to calculate things, manipulate data, display graphs etc. That's what its "python" tool is all about. The use cases usually have nothing to do with programming - the user is only interested in the end result, and don't know or care that it was generated using Python (although it is noted in the interface).

The LLM has to know how to use the tool in order to use it effectively. Hence the documentation in the prompt.
