Unfortunately, yet just another story like this. One of these unexpected usage charges in the thousands appears every month, and with the same automatic denied too. This is one of the reasons I just stopped using these kinds of pay-per-usage cloud services long ago. At best, I still use services that have hard-bounded usage limits, like EC2 from AWS, where one instance can never go beyond 24h/day usage and is always capped, with shutdowns when exceeded, and limited credit cards, too.

It's super frustrating that this is the only option to realistically deal with this issue, since all stories end up the same way: The cloud company just saying "f* you, we don't care, pay up." and legal fees are always expensive :(

Some thoughts on what it costs to be curious these days

In reality, nothing is perfect. Materials are never 100% one material. Rustness is imperfection, the weight and material of the ball, and the place it's attached are also consideration points, how firmly it is attached, and with which material. A "perfect" simulation of the spring itself would have to consider all these variables, and they almost never do.

Show HN: ThesisTide – Tool that rate and classify scientific articles

Hey HN,

Some week ago, I read an article called "Waking Up Science’s Sleeping Beauties" (https://worksinprogress.co/issue/waking-up-sciences-sleeping...) that I saw here on HN and decided to spend last weekend hacking together a tool. It uses AI to classify scientific articles and score them based on their relevance and usefulness for different fields (currently STEM-focused, since the only source implemented so far is arXiv).

It was one of those classic "I can build something like this—it’ll be fun!" developer moments.

This is very much a weekend hack and a POC, so it’s far from polished. It’s missing critical features (like search), and I definitely struggled with the layout (UX/UI folks, I see you). But I’d love to hear your thoughts!
