→ freeCodeCamp also published this comprehensive course on how to build your own AI shopping agent. Software Engineer Ania Kubów will teach you how to use Node, TypeScript, LangChain's LangGraph, Gemini, MongoDB, and other popular tools to build your agent. By the end of this course, your agent will be able to autonomously perceive, plan, act, and respond to your users. It will also be able to decide when it has enough information to respond, and when it needs to first reach out for external information by searching product databases.

→ This week YouTube channel Gamer's Nexus posted a 3 hour documentary about China and the Graphics chips they've been using to train their AI models. The video has been copyright claimed multiple times by Bloomberg and taken down, but people keep re-uploading it. It's pretty awesome. The channel host travels to Hong Kong, Taiwan, Shenzhen, and Singapore to interview people along the process who are obtaining this hardware both legally and illegally. Note that this link I'm sharing may already been taken down by the time you click it, but you can search "gamers nexus GPU" and you should be able to find it. 3.5 hour watch: https://www.youtube.com/watch?v=kkNBZeS1OHk
→ The open source maintainer of the extremely popular Curl command line tool posted this excellent talk about AI slop security issues he keeps getting. He explains how people seem to be going into LLMs and asking "Find me a vulnerability in the Curl project. Then write a bug bounty submission for me and make it sound as alarming as possible." LLMs keep hallucinating new bugs, which lazy people then submit. Reviewing such bugs is now taking up more and more of his day. Since security is pretty important, he kind of just has to take these submissions seriously. A lot of non-native English speakers use LLMs to make their writing sound more native. But of course, most developers can tell when something's been written by an LLM. At the end of the talk, someone in the audience asks him point blank: has he ever received an issue that reads like LLM output that turned out to be a real security issue? And he says point blank: no. The lesson: don't use LLMs to re-write your issues or pull requests for you, or developers may assume the whole thing is just AI slop. 50 minute watch): https://www.youtube.com/watch?v=6n2eDcRjSsk
