Since we're counting model parameters, let me introduce you to a two-parameter model for agentic search that's awesome: It's called BM25. I haven't tried it yet, but I think fp4 will work fine. arxiv.org/abs/2605.10848
The web is disappearing 🕳️ According to a Pew Research Center report, 26% of pages from 2013-2023 are no longer accessible. But that’s not the whole story. In a new study published in Internet Archive's book, VANISHING CULTURE, data scientists working with the Wayback Machine have found: 16% have been restored through the Wayback Machine. 56% are preserved before they disappear. Preservation is the remedy for cultural loss. 📚 Read VANISHING CULTURE free from the Internet Archive 📖 Download & read: archive.org/details/vanish… 🛒 Purchase in print: betterworldbooks.com/product/detail… #VanishingCulture #DigitalMemory #InternetArchive #BookTwitter

Predicting the future is very very hard. Keep working on fundamentals.
If you are a software engineer "experiencing some degree of mental health crisis", now hear this, because I've been coding for 50 years since the days of punched cards and I have a salutary kick in your ass to deliver. Get over yourself. Every previous "programming is obsolete" panic has been a bust, and this one's going to be too. The fundamental problem of mismatch between the intentions in human minds and the specifications that a computer can interpret hasn't gone away just because now you can do a lot of your programming in natural language to an LLM. Systems are still complicated. This shit is still difficult. The need for people who specialize in bridging that gap isn't going to go away. As usual, the answer is: upskill yourself and adapt. If a crusty old fart like me can do it, you can too.
I don't know why this week became the tipping point, but nearly every software engineer I've talked to is experiencing some degree of mental health crisis.
