Hatch v1.10.0 - Hatch hatch.pypa.io [1] Hatch be flyin. This new release of hatch includes support for the new package installer uv which is just mind blowing fast compared to anything else we have in python right now.

How an empty S3 bucket can make your AWS bill explode Imagine you create an empty, private AWS S3 bucket in a region of your preference. What will your AWS bill be the next morning? Medium · medium.com [1] Imagine waking up to a $1,300 for running an example project! That sounds like peanuts for a cloud bill but for an individual trying to learn that hits my monthly budget real hard. That’s what happened to Marciej, make sure you check out the full article and give them a 👏 on Medium if you have an account.

Yes, S3 charges for unauthorized requests (4xx) as well[1]. That’s expected behavior. They offer no DDOS protection against 4xx or 5xx requests against your bucket. Absolutely bonkers that you have ZERO control over this. --- This response just feels absolutely gross. I notified the AWS security team. I suggested that they restrict the unfortunate S3 bucket name to protect their customers from unexpected charges, and to protect the impacted companies from data leaks. But they ...
