DeepSeek-R1's epic pull request (News)

0:28What up nerds? four years to build out infrastructure that will, quote, secure American leadership in AI. On the other hand, there's DeepSeek R1, a Chinese AI lab's MIT-licensed reasoning model that gives OpenAI's O1 a run for its money and only cost$5.6 million to train. It's big money versus big brain. I'm jealous of both. Okay, let's get into this week's news. DeepSeekR1's epic pull request. Speaking of big brain, Zan's son Nguyen opened a pull request to Georgi Gergenov's Llama.cpp repo that doubles the speed of WASM by optimizing SIMD instructions with the following PR comment, quote, surprisingly 99 % of the code in this PR is written by DeepSeekR1.

1:26The only thing I do is to develop tests and write prompts with some trials and errors. Indeed, this PR aims to prove that LLMs are now capable of writing good low-level code to a point that it can optimize its own code. End quote. I can't judge whether this is good low-level code or not because I don't know what good low-level code looks like, but Georgi and Zonsun sure are impressed. Zonson also shared the prompts they used to get the desired results. This, of course, resulted in a long X thread where both humans and robots debate and meme whether or not it's over for folks like us or not quite yet.

2:09Tailwind CSS version 4 is official. Here's Adam Wavin. Quote, Tailwind CSS version 4 is an all new version of the framework optimized for performance and flexibility with a reimagined configuration and customization experience and taking full advantage of the latest advancements the web platform has to offer. End quote. This looks like it was a massive undertaking. It has a new high performance build engine, simplified installation, automatic content detection, reimagined CSS first config and too much more to list here. the most influential papers in computer science history. Matthias Lima opens up the history books to create this admittedly subjective list of influential papers dating all the way back to 1936.

2:58Quote, these seven papers, sorted by date, stand out to me mostly because of their impact in today's world. For each paper, Matthias provides the big idea and why he thinks it still matters to this day. Here's the quick list. 1. On Computable Numbers with an Application to the Encheiden Zone Problem by Alan Turing in 1936. 2. A Mathematical Theory of Communication by Claude Shannon, 1948. 3. A Relational Model of Data for Large Shared Databanks, Edgar F. Codd, 1970. 4. The Complexity of Theorem Proving Procedures, Stephen A. Cook, 1971. 5. A Protocol for Packet Network Intercommunication, Vinton G.

3:45Cerf and Robert E. Kahn, 1974 6. Information Management, A Proposal by Tim Berners-Lee, 1989 7. The Anatomy of a Large-Scale Hypertextual Web Search Engine by Sergey Brin and Larry Page, 1998 He also provides a bonus list of five papers that almost made the list, finishing with this These days we are flooded with new stuff, fresh languages, mind-blowing AI breakthroughs, quantum leaps, and the JavaScript framework of the week. It's all super exciting, but here's the thing. Foundations matter. Without them, we're just piling on new toys without fully understanding the ground we're building on. It's now time for sponsored news.

AI is creating a generation of illiterate programmers. Nemanye Goel has a confession to make. Quote, a couple of days ago, cursor went down during the chat GPT outage. I stared at my terminal facing those red error messages that I hate to see. An AWS error glared back at me. I didn't want to figure it out without AI's help. After 12 years of coding, I'd somehow become worse at my own craft. And this isn't hyperbole. This is the new reality for software developers.

5:55End quote. He doesn't think he's the only one who's become a human clipboard, a mere intermediary between his code and an LLM. Quote, We're not becoming 10x developers with AI. We're becoming 10x dependent on AI. There's a difference. Every time we let AI solve a problem, we could have solved ourselves. We are trading long-term understanding for short-term productivity. We are optimizing for today's commit at the cost of tomorrow's ability. End quote. Does this sentiment resonate with you? If so, see also a linked recent paper on metacognitive laziness. How to improve work from home lighting to reduce eye strain.

6:34Russell Bayless is not an ergonomist or optometrist. He's just a worker from Homer who is susceptible to eye strain, eye pain, and dizziness. In the linked post, Russell shares what he's learned about optimizing home lighting to reduce eye strain. Here's the quick list. 1. An even, diffused lighting environment is the best for the eyes. 2. When it comes to light brightness, too much is just as problematic as too little. 3. Use natural light wherever possible. 4. Quality of artificial light matters. 5. The best lighting for camera is not necessarily the best lighting for ergonomics. 6. Even the perfect lighting environment will fatigue you.

In case you missed it, last week we published two great shows.

7:53Ashley Jeffs on going from open source to acquired. One listener called it very funny and a great guest choice plus interesting story. And of course we had fallout boy, I mean fall through boys, Chris Brando and Matthew Sanabria joining me on ChangeLog and Friends to discuss tools we're switching to, whether or not Go is still a great systems programming language choice, user-centric documentation, the need for archivists, and more. Find those in your feed and look forward to this week when we are joined on Wednesday by Globber Costa to talk about Limbo, a complete rewrite of Sequelite in Rust, and on Friday by Dan Moore for an It Depends style conversation on modern auth strategies.

8:33Have a great week. Leave us a five-star review if you dig the show, and I'll talk to you again real soon.
