At the time Starlink was announced as was rocket reusability. Both were widely mocked and considered infeasible.

Since then Starlink has succeeded, reusable rockets are a reality, ISS crewed spaceflight restored to US.

I expect all that had an impact on the valuation. Personally I wouldn't invest in Elon because his stock is a wild ride but space x has achieved a lot.

If the AI tools can easily find exploits, cannot those same tools be used to harden security? In fact the companies have an advantage over script kiddies: access to more expensive models and compute time as well as professional security engineers

if that's all he did sure, he makes an interesting blog nearly every day jealous or what?

I wonder if fiction writing at that level is like coding. You can learn to type and navigate really fast, but unless you're working on blub software, if you're doing something interesting and novel, you won't actually get to the goal faster. The bottleneck is the ideas, the structure of the story and the development of the characters, amongst many other concerns.

I find Simon's work informative and entertaining; the last thing he can be accused of is low effort. The Pelicans are just a bit of fun icing on top.

are you sure it's non trivial? they posted a 2d image of what it looks like. a fairly simple model of the users wrist and mouse position doesn't seem crazy hard but the devil is in the details

Unlike Uber and Airbnb that did break local laws and got away with it because people wanted their service (and also deep pockets for handling litigation and encouraging politicians to see your way), training an ai is generally not theft.

If I read a physics textbook and now I know some physics do I perform a theft when I use it practice or teach someone else?

New comment by justinhj in "Good Tools Are Invisible"

justinhj — Sat, 11 Jul 2026 01:41:15 +0000

The very first paragraph about macros taking a while is wrong. They are really useful and once in your muscle memory a near instantly accessible solution to small tedious tasks. This is true in Neovim and Emacs.

I also don't use these editors for identity. That is also dumb. I use them because it's fun and they are invisible tools once mastered.

Thanks for sharing that. It's relevant but also a great story about how to struggle against giant corporation bureaucracy and ship against all odds

These kinds of internet dramas get so much more attention here and elsewhere than technical discussion it makes me wonder if Andrew Kelley is a marketing genius.

Same for SFU students too especially the mountain top Burnaby campus.

Same thing happens in Ice Cube's "Are We There Yet" where the characters are driving from Portland to Vancouver but the whole movie is filmed in Vancouver and surrounding area.

"If your company’s cutoff sits at 85, I fail 65% of the time. Same exact resume, different luck."

Sounds like they have replicated the existing recruitment process

The main difference in my proposal is separating git completely from asset management and replacing it with a flexible, scalable system built for that purpose

I see Git as a tool aimed at experts that spend time to learn the tool. Asking non technical people to use it is a mistake. You can build guard railed apps on top of it for them, but probably it's the wrong tool.
