Matrices — Organizing a Sequence of Vectors youtu.be/LvfH1Z3MPuM Our sentence contains several tokens, and each token has a vector. Placing those vectors into rows produces a matrix.

In one small test, Claude Code picked Stripe in all 12 payment runs without being asked. I see a new distribution problem for software companies: the buyer may never compare vendors. Their coding agent has already installed one before they know a choice was made.

Anthropic is pledging 5% of its shares to a public-benefit fund. I welcome the commitment. But a company-owned fund choosing who receives money isn’t the same as people owning a claim on AI’s returns. The percentage matters. So does who controls the payout.

GNU and the Free Software Movement youtu.be/_vcWUQEnF_Y GNU stands for “GNU’s Not Unix.” The name captures an important distinction: the project aimed to provide a Unix-like environment without depending on proprietary Unix code. GNU was not simply a campaign to make software cost nothing. Its central concern was the freedom users had after receiving a program.

The Birth of Unix youtu.be/_vcWUQEnF_Y The story begins in 1969 at Bell Labs, where Ken Thompson, Dennis Ritchie, and their colleagues began developing the operating system that became Unix. Early work took place on a DEC PDP-7 computer, following Bell Labs’ withdrawal from the ambitious Multics project.

Connecting three AI providers to one console creates a fourth security dependency. OpenCode’s breach is a reminder: I’m not just choosing an interface. I’m choosing another place that can hold the keys to someone else’s compute bill.

Linus Torvalds has a message for people banning AI coding tools: “UTTERLY STUPID.” His point: intelligent people he respects don’t shy away from new tools. They learn to use them—and understand what they’re submitting. The standard is competence. Refusing a tool doesn’t prove you have it.

Which one do you use? anthropic, openai or xai?

I’d give an AI agent its own email address before giving it mine. Not because a new inbox makes it safe, but because “the agent said yes” and “I said yes” need to remain different events. Convenience gets expensive when software can borrow my identity.

A developer says Claude helped remove ads and bloatware from his TV. To me, that’s a better AI pitch than generating another app: helping owners undo software they never wanted. The hardware wasn’t necessarily too slow. It was busy serving someone else.

A professor says students brought AI-generated formulas to an exam that already allowed his notes. What bothers me isn’t using AI. It’s replacing a relevant source with a plausible answer, then spending time reconciling them. That’s automation creating its own workload.

From Individual Values to Vectors and Matrices youtu.be/blC_CGqM9S8 A scalar operation works on individual values. A vector operation applies an operation across multiple elements. A matrix operation combines rows and columns to produce a collection of accumulated results.

@wldnfq A true programmer doesn’t use a compiler either. Just a steady hand and a magnet to flip the bits. lol

It’s official: Linus Benedict Torvalds, the man who created Linux and Git, has entered the vibe coding era. The legend himself is letting AI write some code. Somewhere, a developer is still typing “real programmers don’t use AI.”
