EVE Online: The Move to Python 3 Begins!

EVE Online is beginning its transition to Python 3, a move that will involve using the futurize script on 2.4 million lines of code and a manual review of about 20,000 differences between Python 2 and Python 3. The company has historically run on Stackless Python since 2003, with the last major upgrade in 2010 to Stackless Python 2.7. While the announcement does not detail how Stackless will be replaced, the team previously showcased a shift away from Stackless in their Carbon engine for EVE Frontier, leveraging the open‑source carbonengine/scheduler library.

Konstantin Ryabitsev highlights the growing problem of abusive web crawlers that consume excessive CPU resources on git.kernel.org, the official Git repository for the Linux kernel. He notes that at any given moment, 14 CPU cores across five geo‑distributed nodes are dedicated solely to rendering git commits as HTML for these scrapers, surpassing the CPU usage for all legitimate access such as git clones. This issue raises concerns for services like Datasette, which also serve large numbers of crawlable web pages.

Any Nix package, live in your browser

Farid Zakaria’s trynix.dev lets users run any Nix package from the past 13 years inside a browser‑based x86_64 Linux VM powered by QEMU‑WASM. By providing URL‑addressable packages, a user can simply navigate to a link such as https://trynix.dev/?pkg=python3%403.6.2, click "Load," and obtain an interactive shell running that specific package. The platform is also integrated with GitHub Actions, enabling pull‑request reviews that launch the PR’s build directly in the browser via trynix-preview.
