Quoting Addy Osmani, Morgan Westlee Lunt, and Qing Wang

The article discusses a shift in code review practices, moving from a final gate to continuous review that functions like spellcheck during coding. It highlights how the Claude Code team uses the Claude AI to catch routine mistakes before human reviewers intervene, allowing developers to focus on higher-level issues. The piece references insights from Addy Osmani, Morgan Westlee Lunt, and Qing Wang on this evolving approach.

Be alert: targeted attacks on prominent Rustaceans

The article warns of a targeted campaign against prominent Rust developers and crate owners, aiming to compromise their devices and accounts to publish malware. Attackers use seemingly legitimate video calls to trick targets into installing malicious software or executing commands, such as a fake audio codec or clipboard command. A recent supply‑chain attack on the array‑ref crate illustrates the threat, and the author suggests using dependency cooldowns as a defensive measure.

Just a rumour of a bug is enough to find a security exploit these days

The article reports that rumors of bugs in open‑source projects now trigger rapid security exploits, with automated agents probing for vulnerabilities within minutes of a patch being discussed. Anil Madhavapeddy demonstrates how modern coding agents can exploit even minimal hints, and rclone maintainer Nick Craig‑Wood notes a dramatic spike in security disclosures and delayed CVE assignments. The post highlights the need for new processes to protect open‑source communities from swift exploitation.

Claude Cowork and chat are now one Claude

Claude Cowork and the standard chat interface are merging into a single Claude experience, allowing users to hand over tasks or ask quick questions that the system will continue to handle even after the laptop is closed. The rollout will begin with Pro and Max plan users across web, desktop, and mobile, and will extend to new users on these plans over the coming weeks. This integration suggests Claude is evolving into a general agent, simplifying the distinction between Cowork and regular Claude usage.

Your executable is a SQLite database

Farid Zakaria shows how to create a SQLite database file that can be executed directly as a Linux binary. By setting the SQLite file format’s 4‑byte application ID to "SELF" and arranging ELF components into SQLite tables, a small C interpreter can extract and run the necessary parts. The technique can be registered with the kernel via binfmt_misc so any file matching the pattern is automatically executed.

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.
