Building OpenCode with Dax Raad
5 beliefs, in the piece's order there
Their words
the strategy that we know how to play really well is to pick one temporary bad guy and then galvanize all their competitors to push something forward against them.

Building OpenCode with Dax Raad youtube.com
Their words
none of our competitors are crushing us either. Like no one out there is using AI so well that they just like we can't even compete, right? Um, and we're in the coding agent space. All our competitors are super into AI. So you would think in our space there would be like uh a huge gap, but there there just isn't.

Their words
The moment you ship something, you're stuck supporting it forever. And by supporting, it means any future feature you build is going to like interact with it. So you still have to be very conservative with what you put out there. It's hard to undo anything. Just cuz we can ship 10 times more doesn't mean we have 10 times as many good ideas to ship out there.

Gamified learning is a bit like wrapping medicine in candy. Yes, it may help some students swallow some instruction they otherwise find bitter, but in practice it’s easy to pull off the candy, consume it, and throw the medicine away.

Their words
General problem solving abilities are neither learned nor taught. While some problem-solving methods have broader applicability than others (such as the scientific process of hypothesis testing), students learn these methods better when they’re explicitly taught rather than simply giving students projects and hoping they’ll reinvent them on their own.

Unfortunately, I completely agree that the United States of America is rapidly descending into all-out conflict between left and right. The Luigi left, Kirk killers, anti-Tesla terrorists, and Altman attackers are already in shoot-on-sight mode against conservatives, libertarians, and technologists. The right isn’t there yet; they’re called reactionaries because they only react, so they’re always one cycle behind. Thus, the left has already started shooting while the right is still “only” mirroring the lawfare of last decade’s left. But anyone can see how incandescently angry the American rig… Quoting @romanhelmetguy Gonna try to explain this to tech CEOs again: Young Americans are pissed. They feel betrayed. Half have embraced the far right & want to cut off your access to cheap foreign labor. The other half have embraced the far left & want to cut off your head. One side will win. Choose.

I still meet people convinced that AI coding tools will soon reach a point where code quality, design, and even architecture are "solved". So I ran a small ad-hoc experiment. I’ve been working on a CLI tool and let agents plan and implement a first functionally correct version. I provided strict instructions around testing strategy, workflows, and implementation constraints. But I deliberately removed the @codescene MCP and the safeguards I normally rely on. Unsurprisingly, the resulting code suffered from a ton of problems. It would have been a shaky foundation to continue building on. How s… MCP Related

Why Rust is different, with Alice Ryhl
5 beliefs, in the piece's order there
Their words
I think this is kind of leads to another way that Rust really helps with reliability, which is that if you're refactoring, I think Rust is really good at telling you all the places you need to update. I've done this sometimes where I would refactor something. I change the code. I change the return type or whatever it is, and then I just fix the compiler errors and until the compiler stops shouting. And then once I've done that, I've updated every place I need to update.
