Why people use Deno and Bun over Node? I think it's neat that there are competitors for JS runtimes, but I really don't understand what advantages I'd get by swapping to one of these over Node. Bun has no REPL and worse JS engine, Deno is just Node with a restrictive, annoying permission system and no sqlite. Both claim better performance, but that only seems true in cherrypicked benchmarks, and in my tests (granted…

I switched to Deno because it is the only option out of the 3 that allow monorepo workflow without building .d.ts files. Bun and Node both do type stripping or compiling of TS, but it only works for the entry package of the running script, not any of the linked dependencies from the same repo. There are still things I dislike about Deno, but it really does make package development a lot simpler. JSR is a great upgrad…

I’ve set up a monorepo before that subpath exported plain TS across packages and it just worked (pnpm). You may want to try again.

I thought the prime bet was that the winning lab who reaches takeoff through recursive self improvement will make a galactic superintelligence.

I don't think this race to superintelligence idea should be taken too seriously. It is great for headlines and get peoples imaginations up. It is mostly a marketing gag. I look at superintelligence this way: software engineering used to be considered amoung the most mentally demanding jobs one can have. And in this field more and more people give up large parts of their job and become approximately product managers t…

The people in that community have been talking about superintelligence for decades and it’s part of an ideology. It’s not some recently-invented story for headlines.

Isn't that mostly just enums? Is there anything else that doesn't run as valid JS if you strip the types (and maybe some other extra keywords)out? Genuine question, in my head there's not much, but TS has a few weird corners I maybe haven't used

enums and decorators mainly. There are also subtleties such as having the ts file extension in imports. Also imports aren't transpiled in cjs so you need to need es modules. I'm using it in my projects with no issues.

Ah yeah I forgot about decorators - I’ve worked with angular before but clearly I managed to erase all knowledge of it from my brain.

Outside of that I’ve barely seen them used in typescript, they’re not really idiomatic in react projects

1. At least 99% of all species that ever lived on Earth are now extinct. I.e., that's life. 2. "But for a beautiful moment in time we created a lot of value for shareholders."

Failure for those species though.

What a strange way to view life.

At least you could go out with the accomplishment of having out-competed some other species along the way.

They know the problem. It's better than they don't.

All these complaints about Claude code are mostly resolved if you pay for your usage with direct API pay as you go. It’s not cheap but nearly all the complaints I see about Claude code are due to the fact the subscription plans seem unsustainable from a cost perspective.

I use the subscription and so far have had no problems.

I wonder why Anthropic chose to spend money on Bun when they could have easily spend that resource on Go which is fairly easy to use and fast. I'm sure their SWEs could easily everything things in Go. Anyone have insight on why?

JS is used because it's (still) the only code you can run in a browser. Although node and bun are regular OS processes, their use/popularity traces back to that browser environment one way or another.
