<p>>teaching functional programming to people trained in OO: Some people's model just breaks, while others quickly see the similarities, and how one can translate from a world of vars to a world of monads with relative ease.<p>Besides OO -> Functional this applies everywhere else in Computer Science. If you understood the fundamentals no new framework, language or paradigm can shock you. The similarities are clear once you have a fitting world model.</p>

<p>What were your syntax stumbling blocks? I must be honest I've used jq enough but can never remember the syntax. It's one of the worst things about jq IMO (not the speed, even though I'm a fan of speedups). There's something ungrokkable about that syntax for me.</p>

<p>Replying here because the other comment is too deeply nested to reply.<p>Even if it's once off, some people handle a lot of once-offs, that's exactly where you need good CLI tooling to support it.<p>Sure jq isn't exactly super slow, but I also have avoided it in pipelines where I just need faster throughput.<p>rg was insanely useful in a project I once got where they had about 5GB of source files, a lot of them auto-generated. And you needed to find stuff in there. People were using Notepad++ and waiting minutes for a query to find something in the haystack. rg returned results in seconds.</p>

<p>In Germany I'd say you still make more with white collar, if you have a job. The problem for Gen Z though, is that they aren't hiring for junior positions.<p>Still if you go blue collar you have to build your own business.</p>

<p>The problem is rather that Java doesn't have generics and structs, so you're kind of forced to box things or can't use collections.</p>

<p>Nice. My test was always a blond bald guy. It always adds hair. If you ask for bald you get a dark haired bald guy, if you add blond, you can't get bald because I guess saying the hair color implies hair (on the head), while you may just want blonde eyebrows and/or blond stubble.</p>

<p>Not unlikely that you're talking to a lot of AI-based AI boosters. It's easier to create astroturfed comments with chatbots than fixing the inherent problems.</p>

<p>I'd add to this, any moderately involved logical or numerical problem causes hallucinations for me on all frontier models.<p>If you ask them in isolation they may write a script to solve it "properly", but I guess this is because they added enough of these to the training set. But this workaround doesn't scale.<p>As soon as I give the LLM a proper problem and a small part of it requires numeric reasoning, it almost always hallucinates something and doesn't solve it with a script.<p>If the logic/math is part of a larger problem the miss rate is near 100%.<p>LLMs have massive amounts of knowledge, encoded in verbal intelligence, but their logic intelligence is well below even average human intelligence.<p>If you look at how they work (tokenization and embeddings) it's clear that transformers will not solve the issue. The escape hatches only work very unreliably.</p>

<p>>I definitely agree that in principle a computer can drive with cameras alone.<p>Obvious things first, cameras have way worse contrast and low light sensitivity than human eyes.<p>Humans have much more evolved logical thinking capacity, even the stupid ones can figure stuff out that modern AI struggles with.<p>Humans have other sensors, too that they use to plausibility check the picture they see. I.e. one of the best sensor fusion systems on the planet.<p>When in doubt humans can figure out whether it's a lens occlusion or a some other artifact in their vision by virtue of moving their head around.<p>There's probably other things I'm not thinking of. In any case to make full self driving work we should first start by using all available tech to make it safe. When you have safe tech you can slowly start removing individual sensors while verifying that safety remains high. As the experience and system evolves there will be optimization potential.<p>And until we have that low light thing and high contrast figured out, camera alone doesn't cut it.</p>

<p>Exactly, you would probably also pay for a good one. I tried maybe 10 and gave up. I now carry a small booklet where you can rip off the pages, for notes and todos. Still way better than the phone apps</p>

<p>Which is not getting better.<p>I'd pay you 10€ for a TODO app that improved my life meaningfully. It would obviously need to have great UX and be stable.  Those are table stakes.<p>I don't have the time to look at all these apps though. If somebody tells me they made a great TODO app, I'm already mentally filtering them out. There's just too much noise here.<p>Does your TODO app solve any meaningful problem beyond the bare minimum? Does it solve your procrastination? Does it remind you at the right time?<p>If it doesn't answer this in the first 2 seconds of your pitch you're out.</p>

<p>I think the problem is lot's of people here don't have much kitchen experience and underestimate the effect.<p>But anyway, I think a pre-seasoned vegan ready made burger patty should only be compared to a pre-seasoned meat burger patty. It's an Apples and Oranges comparison with little meaning.<p>If you compare the high sodium of a vegan ground beef replacement with ground beef, that's fair game. The one from Beyond here is actually a good example of too high sodium. I won't judge. I only care about the comparison, not the company.</p>

<p>>it has way more sodium than ground beef you'd buy at a grocerty store<p>We're not comparing fairly here. A finished hamburger patty is not pure ground beef. Did you ever make a hamburger patty yourself? You add salt and spices at a minimum.<p>A more fair comparison would be looking at store-bought hamburger patties. That's the same category of food.<p>I just compared Beyond (0.75g salt per 100g) and block house American Burger (0.88g per 100g). The patties are somewhat similar in weight, too (113g and 125g). So both in absolute, and weight relative amounts the Beyond burger has less sodium.</p>

<p>This might be happening, too, however B2C advertising and heavy astroturfing is a sure sign that they don't even think they're close to this goal.<p>The average consumer pays the least for subscriptions and asks most uninteresting questions to the AI in terms of gaining insight. The only goal here can be upholding the narrative that everything will be AI soon™.</p>

<p>>But instead, all you see are FOMO propaganda to get devs to adopt the tool with no asking if it actually helps the devs do their job.<p>If (big if) LLMs/AI take over all of knowledge work the first thing you'll notice is that the first company getting to the point of automating all knowledge work will close off their models to the public, not advertise it, and take over every business on the planet.<p>You wouldn't waste a dime on advertising, influencers, or convincing people to use your product.<p>Taking over every business in the world seems more lucrative than selling $20 subscriptions to people.</p>
