AI-Written Code Is Still Your Code. Are You OK With That?

๐Ÿš€ Check out this trending post from Hacker News ๐Ÿ“– ๐Ÿ“‚ **Category**: ๐Ÿ’ก **What Youโ€™ll Learn**: Coding agents keep pushing the cost of writing software close to zero. This is valuable because writing software has historically been a big part of the work needed to ship software. For a lot of projects, testing, documenting, packaging, and other code-adjacent work have consumed much less effort, when theyโ€™re done at all.But the writing part has always bundled with it another important part that weโ€™ve been taking for granted: understanding software. Aside from the most basic comp sci homework problems, itโ€™s pretty hard…

This means that we are masters of and can allocate our own CVE identifiers. For any security problems within our territory, it is we who decides if the issue should get a CVE or not. No more bogus CVEs. 57 CVEs During these years we have published fifty-seven separate security vulnerabilities with their associated CVE identifiers.

โœจ Discover this awesome post from Hacker News ๐Ÿ“– ๐Ÿ“‚ **Category**: ๐Ÿ’ก **What Youโ€™ll Learn**: Somewhere around 11 PM on a Tuesday โ€” it's always a Tuesday โ€” you will attempt to catalog a book printed in Lyon in 1642 and the software will ask for an ISBN. Not politely. Insistently. A red border. A validation error. A small, pixel-perfect indignity. Your book has a colophon. A printer's device. A privilรจge du Roy. It has survived the Fronde, two world wars, and at least one previous owner who annotated it in pencil. What it does not have is a thirteen-digit…

Deduplicate all files in the wheel cache by charliermarsh ยท Pull Request #21327 ยท astral-sh/uv ยท GitHub

โœจ Explore this trending post from Hacker News ๐Ÿ“– ๐Ÿ“‚ **Category**: ๐Ÿ’ก **What Youโ€™ll Learn**: ## Summary When content hashing is enabled, we currently allocate and zero a new 64 KiB buffer for every file we copy and hash during streaming extraction. This PR reuses one buffer across the wheel instead. For the PyTorch wheel used in the benchmarks, that reduces buffer allocations for hashing from 11,120 to one, while keeping the buffer size at 64 KiB per active wheel. The following measurements compare #21327 at `a188b8e833aef3c3b4b60a32ed9fafe6ac74186a` with this optimization applied on top, before moving the change onto `main`. They…

I run Wirewiki.com, a website to inspect internet infrastructure like domain names.
