I’m not OP but every time I post a comment with this sentiment I get told “the latest models are what you need”. If every 3 months you are saying “it’s ready as long as you use the latest model”, then it wasn’t ready 3 months ago and it’s not likely to be ready now.

To answer your question, I’ve tried both Claude code and Antigravity in the last 2 weeks and I’m still finding them struggling. AG with Gemini regularly gets stuck on simple issues and loops until I run out of requests, and Claude still just regularly goes on wild tangents not actually solving the problem.

Have you tried it with something like OpenSpec? Strangely, taking the time to lay out the steps in a large task helps immensely. It's the difference between the behavior you describe and just letting it run productively for segments of ten or fifteen minutes.

I'm Portuguese, so read this as a view from outside. Brexit traded rigid limits on national action for soft limits. It is bonkers, because the soft limits are much harsher!

Take, for example, trade policy. Facing trade tariffs from the US, Europe can call the bluff, the UK is way too small to have any cards on the negotiating table. It is much better to be in a huge economic block than to face the bully alone. On paper you have more formal power alone, in practice you have no power whatsoever on your own.

The absence of formal action limits can be deceitful. Limits are not only there anyhow, they are worse for you outside the economic block.

So, no, you won't be better in 20 years. In fact, given the direction the world is going, you'll be worse than even today.

The article explains they they are not safe nor effective

No. The article explains they do not cure the underlying issue, whatever it is. We have many such drugs, widely accepted as safe and effective.

Great idea, nice proof of concept. It'd be nice to see a translation into English after we finish the sentence, as it'll inevitably introduce words I don't known yet, and there's a learning opportunity.

master in the context of git never referred to slavery, it's derived from the "master record" used by the audio industry. The process of renaming the default branch was started by someone outside the project who never contributed to git in any way before or after that.

Thankfully, there are many countries outside the US where this sort of 1984-style language policing is not accepted and we'll continue "clinging" to our "legacy terms", tyvm.

Portuguese has the word "mestre" from the same Latin origin. Since it has evolved in a separate context, it may give a glimpse of the original meaning, way before slavery. A "mestre", in Portuguese, is one of three concepts:

- Someone who has mastered some art;

- A teacher;

- The lead artisan in a team, the one who has mastered the art, teaches and leads.

The slave master is a very narrow interpretation on these meanings, and the woke push against the word is myopic. The word has a long history, none of it connected to slavery.

    > I am curious where this comes from, because my thinking is the absolutely opposite. As much business logic as possible should belong in the model.

The opposite of this is what Fowler has called an "Anemic Domain Model"[0] which is ostensibly an anti-pattern. What I've learned from my own experience is that with an anemic domain model, the biggest challenge is that the logic for mutating that object is all over the codebase. So instead of `thing.DoDiscreteThang()`, there could be one or more `service1.DoDiscreteThang(thing)` and `serviceN.DoDiscreteThang(thing)` because the author of `service1` didn't know that `service2` also did the mutation.

Domain models are hard to do well and I think the SOA era brought a lot of confusion between data transfer objects, serialized objects, anemic domain models, and domain models.

I tend to draw the line at intrinsic vs extrinsic behavior. The model layer must be able to maintain all intrinsic properties. Whenever it would talk outside the application, it's beyond the domain of the model.

Taken to the extreme, you could model all intrinsic constraints and triggers at the relational database level, and have a perfectly functional anemic domain model.

sergiosgc commented on Ask HN: How to Learn 'To Think'? · Posted by u/cannnot_think

As with most tasks, you learn by doing. You can't learn to play tennis from a book, in the same fashion you can't learn to think from a book.

Find an area where you have to disassemble large problems into small ones, where you have to plan a few steps of the solution. Any knowledge area will do. Writing was suggested in another comment, it's a good playground. As is programming, where there is ample literature of puzzle problems to solve. Algebra, if you are so inclined although, beware, it veers a bit into the abstract. There are physical hobbies with that characteristic too: anything involving woodwork or building stuff out of parts (or disassembling and reassembling, like mechanics).

Having picked up a hobby, apply the hours. Start with stuff you can do, don't overshoot complexity. Then, evolve from there. As with all new activities, embrace failure. Don't just accept failure, expect it, learn from it, step on past failures to evolve.

P.S. I can't imagine not having an inner monologue, or its dual, spatial imagination, but a relevant part of the population doesn't have either, with no ill effects on the thought process. It's amazing, to me, but it seems they are not required for thinking.

Teslas are very stale inside. The "tablet as 99% of the interface" is horrible and should be left in the 20teens. Physical buttons for the most important interactions with the car are in all ways better. I understand why they do this, they are going all in on autonomous driving, so sure. I recently purchased an EV and when I sat in the Tesla, I hated it. I don't want to play the iPad driving game.

sergiosgc · 2 years ago

I know this is a popular opinion, but you'll be hard pressed to find a Tesla owner that shares your opinion. It could be self-selection, or it could be that Tesla's user interface actually works very well.

In my opinion, it's the latter, after observing how my parents adapted to driving a Tesla. I was actually concerned it'd be a hard transition, but I only had a couple "support calls" related to the car.

As somebody potentially in the market for an EV, I can say that for me, Musk is most definitely a factor.

Not the only factor, to be sure, but the off-putting icing on an otherwise average cake. If Tesla were the only decent EV in town, I might hold my nose through Musk’s behaviour and buy one. They aren’t, though, so I don’t have to.

The other major factors in my decision are the very public QA issues, safety issues, and questionable design decisions (eg. all-touchscreen controls, dangerous “full self-driving” fallacy) that, combined, leave me thinking “yeah, maybe I’d rather buy from a somewhat more boring company with a longer history of _making safely-working cars_”

I don’t kid myself that the heads of most car companies are necessarily decent human beings who align with me ethically or politically, but all other things being increasingly equal, why would I opt for the one run by a childish unstable egomaniac who stands in loud, public opposition to most of what I believe in?

sergiosgc · 2 years ago

Maybe because VW, for example, has actually skirted pollution laws, with intent. Or because PSA management publicly derides any effort for EV transition. Or maybe because Toyota has for 20 years falsely promised EV fuel cells/engines in the next five years, all the while happily selling ICE vehicles.

If you look closely at any big corporation management, they are all egomaniacs. Just not childish enough to publicize that fact.

Yeah but someone who got a Model S in 2018 and upgraded to a Model S in 2022, is probably not going to buy the same looking car in 2025

Step back a bit and ask yourself: Why not? If it's a great car, and if it has been technologically updated, should you really care that much about a new front grill design?

We consider cars more fashionable than shoes.
