- David Heinemeier Hansson So freaking cool! We're running Omarchy ads in the center of Copenhagen on Rådhuspladsen this week. Design by @Dennis_Rye and funded by @sonderby 👏 There's even a billboard generator available if you want to do this in your city: github.com Quoting@Dennis_RyeOmarchy week has started in Copenhagen!

- Pieter Levels Cheap hotels are now generally better than expensive hotels because they're not run by ESG eco hotel brands whose ACs gaslight you and make you wake up at night in sweat! Crazy Quoting@johnkonradMy month-long California vacation is over. I spent most of it on my yacht—but I also stayed in a number of motels. Yes. Motels. Cheap motels. I normally stay at Hiltons. The first week of my vacation, I did. Then I woke up sweating in the middle of the night because of lousy AC controlled by a gasl…
- Pieter Levels You're right, it was an elementary school not a military base. I'm sorry for the confusion. Would you like to learn more about elementary schools? Quoting@InsiderWN#BREAKING: Pentagon blames flawed intel and AI for strike that killed at least 123 Iranian children.

- Pieter Levels I believe nation states will keep becoming less and less relevant and that in the future everyone will be a nomad Most nation states (and well governments) barely function anymore through 100+ years of democratic baggage from laws and regulation that can't be reversed People can't save their countries or governments anymore through people's initiatives or getting into politics, because the systems are so old and in full gridlock Globalism has deservedly gotten a really bad rep the last 5 years though as we were too naive about it, but I think we should keep the good parts from it We should no… Quoting@ramenladVery cool. I’m curious: do you believe digital nomading will continue to grow given the potential disruption of all things digital that’s upon us? Sorry, had to quote to reply @levelsio :)
- Pieter Levels 🌎 Now redesigning the https://t.co/HGCLKS5BD6 profile trips globe from scratch I've always wanted to add space trips, so starting with the moon here which you can add as a future trip, also adding Mars etc. Other trips also need to work here though like going into orbit like @satofishi did on @SpaceX's Dragon capsule which will be more in reach for more people hopefully pretty soon! Quoting@levelsio✨ Finally built a timeline for https://t.co/HGCLKS5BD6 now I always wanted to make my site a bit more social, because I had profiles and trip overlaps and you could kinda see where other people went, but not something like this So on this new page you can see people near you, where everyone's trave…

So you can see people you follow, or just everyone I hope I can improve it more so the site will result in more serendipitous connections, especially now that's it's free Also nice you can see where people will be in the future… Quoting@levelsio🌎 https://t.co/1z6UN2d0nh globe is now ready for space travel too 😊

- Mitchell Hashimoto New week new demo! Today I want to showcase the CLI to control the @superlogical multiplexer. The CLI is an extremely powerful tool for automation and hooking into other tools like editors, agentic coding tools, and more. And, it's super fun! Everything you can do in the GUI, you can do via the CLI. Actually, you can do more in the CLI. You can create sessions, run commands, make splits, move things around, change focus, simulate any input device (key/mouse/etc.), wait on scripts, and more. There are a couple unique parts of Rex I'm showing off here too: our streaming event system that any cl…

Opus is the best frontier model, and the one to start with.
WasStart with Opus. I'd say start with Opus. It's the best frontier model.
NowBut to answer your question, the best model in general right now is Fable. The second-best model, in my opinion, is Opus 5.

David Heinemeier Hansson
An open-weight model is already all anyone needs; it is as good as the frontier models.
On changing their mindWhen I was instructing the agent, I was like, "Oh my God, Kimi's just as good as these other models."

The ideas in software originate with humans; agents build what people tell them to build.

Now that everyone can build apps with AI, distribution is the thing that separates who wins.
WasI think the challenge is that everyone can now build apps But 1) almost nobody has distribution (like an audience), or 2) the money to pay for distribution (ads or UGC), or 3) the creative genius to get distribution for free (classically called guerilla marketing)
NowI thought it'd be distribution but who knows, obviously creativity and ideas, but if you can copy a successful app in an hour, then how does that differentiating work?

Basecamp was the best business idea he will ever have: lightning is not caught twice, and a founder's second idea is rarely as good as the first.
WasI know this from experience because I've been trying to build a lot of other businesses since. And some of them have been moderate successes, even good successes, none of them have been Basecamp. It's really difficult to do that twice.
NowAnd I have no shame in saying that Base Camp was the best idea objectively in terms of a business that we've ever had.

For a web developer Linux is simply better than the Mac: closer to what you deploy on, with phenomenal tooling and a reproducible setup.
WasBut I have come to realize that as a web developer, Linux is just better. Linux is just better. It's closer to what I deploy on. The tooling is actually phenomenal.
Nowanyone who's working with the web, who's working with Ruby, who's doing DevOps, they should be on Linux because first of all, that's closer to what we deploy.

Mojito Island is a mirage: there is no retirement for ambitious people, and leisure without purpose is misery, not happiness.
WasMojito Island is a mirage. It always was. There is no retirement for ambitious people. There is no just sitting back on the beach and sipping a mojito for what? For two weeks before you go damn crazy and wanna get back into the action?
NowI think that's the other big misconception that some people have about wealth is that they conceive of it as some sort of checkpoint. Like once you've made it, then you can just kick back in leisure as though that was happiness.

Peak programmer has passed: the economic value of writing code by hand has peaked, and Jevons' paradox will not bail every programmer out.
WasIt may no longer have as much economic value as it once did. I think that I'm quite convinced is true that we perhaps have seen the peak.
NowSo, I do think it is correct for the average programmer to think maybe we've seen the best of the golden days.

The joy of a programmer is to type the code himself; promoting yourself out of that makes you a project manager of a murder of AI crows.
WasThe joy of a programmer, of me as a programmer, is to type the code myself. If I elevate myself, if I promote myself out of programming, I turn myself into a project manager. A project manager of a murder of AI crows as I wrote the other day.
NowI have been hyper accelerated as a programmer. It's a different kind of programmer, but it still has the same affinity to aesthetics, at least when I'm producing Ruby code.
