@RaminNasibov Once I found that gravity is not a force but acceleration from the ground towards outer space, and it blew my mind.

In short, it’s because js is incredibly shitty language, so it’s extremely hard to translate it into specialised bytecode. Overall, the pipeline is similar: source code -> bytecode -> machine code. It’s just semantics of the language which disallows efficient machine code translation. BTW, Dart is properly designed in that sense, and Dart code performance has to be similar to Rust in WA.

@LukasHozda I think smartphones killed this category. You can do simple office work on your phone.

@oprydai That’s true. But is intelligence a compression?

@denbvk @nicbarkeragain There's a reason media other than books exist: films, series, music. Text isn't the best way to communicate everything. An image often explains an idea far better than pure text. Deep thinking and work are impossible with text alone.

The entire idea of AI code generation is based on the assumption that a "prompt" can express your technical intention. But as soon as you start to get good at programming you stop thinking about it in english and instead switch to some abstract mental representation.

@typecraft_dev You mean the biggest architectural mistake in PG, so even made Uber do a back migration to MySQL?

@systemdesignone Because we didn’t have a good way to distribute proprietary binaries before Flatpack arrived. And it’s a bit too late for the party. You see, you need not only technical rigour, but also business initiatives for commercial players to invest in this crap.

@matteocollina I had a similar experience. They blocked regular code review. I think it noticed that some logic is a security hardening; this false positive suite shocked me.

My long Fable 5 session C++ was blocked without anything having to do with Cyber. Sigh. Model is great, but the rest is really annoying.

Software engineering is a great little insight into how capitalism works more broadly in that developers have spent the last 50 years making new tools that everybody else has to learn, inventing new libraries, working on projects that threaten to make everybody else's engineering skills obsolete, and this all culminates in AI tools that some people think will totally eliminate the profession. And so it's natural to ask yourself, "why?" Why would they do this? Why would an industry make the tools to make themselves obsolete? There's a simple answer: it's because people have *individual* incentives that override the collective incentives. Software engineers are in *competition* with each other. They aren't a single, coherent, cooperative entity. And it's the individual incentives that are operative. This is true all throughout capitalism. Many socialist arguments are built on an inability to understand this core fact.

@dadbod2100 @nicbarkeragain Sure, so I guess your approach is a Techno King who just tells everybody how many spaces to use for indentation. Actually, it sounds good. Where do I apply?

Question to all the people upset about Anthropic adding safeguards to Fable. I think most of you come from a libertarian viewpoint? But from that perspective, isn't it also Anthropic's right to do whatever they want with their model?

@teej_dv I’ve built a couple. My learning is that it’s harder than it seems, and to make it prod-ready, it’s like months, if not years, of work. But it’s fun though.
