<p>>do you really need SOTA models for everything?<p>For work in which you are in the loop, absolutely. Do people not value their own time or something? Why in the <i>world</i> would you use less than the best LLM available to you? You're not going to run out of the $20 plan even if you use Opus 5.5 at xhigh and code 8 hours/day (assuming you're doing it piecewise using a Claude product) so what exactly are you conserving by using something inferior?<p>For large continuous volumes of programmatically submitted LLM tasks, sure.</p>

<p>Jev's marketing can't be that good because as a dev I was thoroughly unimpressed by it. Isn't it just structured output? If you embed LLMs in your applications, you were almost certainly using structured outputs already. Maybe they did additional training on top of some open Chinese model, but almost always this makes things worse not better. There's no way Jev is better than a 5-5 series Claude model at any kind of classification task.<p>Like that old adage "that's a feature not a product" - Jev is just a system prompt, not a product.</p>

<p>There is a difference between wanton "vibecoding" and AI-assisted coding.<p>The latter still gives you many-X productivity improvement while the quality is pretty close to handwritten code.<p>LLMs are <i>still</i> not good enough where you can unleash it upon a huge codebase and get good results btw. Quality goes to shit once a context uses up around 50k-100k tokens. That's often only enough for one feature change and whatever validation the LLM wants to do for it.<p>It's fair to say that most new software is written with AI help, but that doesn't mean someone just prompted a few things and pressed deploy.</p>

<p>The README defines the expected behavior of my API endpoints and the overall program in natural language. Some repos have additional documents (like DATA_MODEL.md) that defines the nitty gritty of the distributed concurrency characteristics, data invariants and such other things.<p>Claude Code (Opus 5.5 xhigh), when it makes changes, tests the relevant endpoints for behavior based on what it touched. You could also just explicitly ask it to as a follow-up prompt. You do need to have instructions on how to set up a test environment or use infra for which dev env testing is well-documented online.<p>And yes, it's non-deterministic. It's not gonna test everything exhaustively or systematically like a fuzzer. It's basically doing what a manual QA would, at best. It probably doesn't even cover every edge case each diff. But I'm fine with this tradeoff for not having unit tests.<p>Caveat emptor:<p>1. These are relatively small-medium programs (~10k LOC) where the frontend and backend code reside in the same repo, and the frontend is strictly a web app, and where 100% of the functionality can be tested in the dev environment (incl the database).<p>2. I'm the only person working on these repos right now.<p>3. I read every line written by the LLM and have things I don't like refactored or stashed and rewritten with a modified prompt, mostly based on intuition.<p>>How many tokens does this process take?<p>I genuinely believe anyone who exceeds usage on a $20 plan doesn't use Claude Code correctly. Always use a new context wherever possible. Always make surgical changes (or, broad changes with well-defined success criteria). For anything complex, get a plan from the LLM at least so that you know it understood your ask. Ctrl+C and `git stash` are your best friends. Keep everything clean, don't build castles on garbage. In the LLM era ironically you should never put off tech debt because it will just compound.</p>

<p>Exactly. The LLM is actually going to replace PMs not SWEs. It's far more likely for a SWE+LLM to encroach into a PM's role than a PM+LLM to encroach into the SWE's role.</p>

<p>I take the complete opposite approach which is to have <i>zero</i> unit tests now, because LLMs are excellent at both reviewing code to understand what's going on, and also doing manual QA given environment instructions. Lots of unit tests will just bloat the context which ultimately dilutes the quality of the LLM's work and also creates additional work (it has to update the code and the tests each time).<p>Unit testing imo is pre-LLM. It was mostly to keep the human honest because the human can't possibly read all the code to make sure nothing broke.</p>

<p>I saw that post on LinkedIn and my immediate thought was just use AI to explain the code to you before committing. I do that and it's quite good and fast. I personally prefer to understand every line of code that's committed with my name on it, or in a repo that I own. I guess it's passe now to expect this of everyone?<p>Basically, don't let the AI coding era peer-pressure you into being a bad engineer.</p>

<p>I'd still want the most intelligent human in the room to work with the AI.

Can a layperson prompt the LLM like that?<p>"Garbage in, garbage out" is a polite way of saying the LLM's output is a reflection of the prompter's own intelligence.</p>

<p>I think if you're stuck on that question, <i>her</i> manipulation poked through the silver screen and worked on you.<p>To me the subtext of the movie was that a sociopath's manipulation is so strong that <i>even</i> against the heavy counterforce of the filmmaker's bias, it makes it through. I agree with TFA's general premise that the film forces you to confront how easy it is to deceive you -- but it's not the filmmaker who's doing the deceiving. Sociopathic manipulation is about sparking doubt. Gaslighters don't need to prove anything, they just need to plant a "but what if" in some corner of your mind. The fact that the author felt compelled to write TFA at all is ironically a product of <i>that</i> manipulative power.<p>Another way to think of it is: the documentary makes you think whether, if you were in the room with her in the years that Theranos was operating, would you have fallen for it? If you feel the need to write apologia after watching a documentary that's basically a hit piece, you know the answer.</p>

<p>The fatality rate of an accident includes all parties involved. Most often when a Tesla hits someone, it kills the other guy, since it's basically an ultra-dense block of mass that can do 0 to 60 in 3.5 seconds, <i>very quietly</i> and without launch control[1]. Teslas are incredibly safe for the people inside the Tesla.<p>[1]Lots of other cars have technically faster times than Teslas, but most of them require launch control, good tires, and sound like the engine's about to explode. You can floor the Tesla at any time and the software will deliver however much power it can without slipping.</p>

<p>There is mean-spirited racist humor and non-mean-spirited racist humor. Would you say Russell Peters is a racist?<p>True racism is about exclusion. If you'd never meaningfully associate with a person of some certain race(s), you're a racist. Doesn't matter if you're the most polite soul in the world.<p>There are people who have traveled the whole world, eat ethnic food all the time, do yoga, vote left etc but would never make friends with someone not of their own race. They are the real racists. Racism is simply defined as whether you consider race to be a meaningful way to classify people.</p>

<p>I mean sure, you could use casual meetups to meet new people, but friendship really develops and exists in a 1:1 context. I re-read the root comment and it seems like the person has the right approach initially - meet at a meetup, invite for 1:1 coffee afterward.<p>But then he invites them to his potluck and I think the friendship dies there. That potluck is like a graveyard of all his potential friendships. It just becomes a "hangout group" i.e. fake friends. Also, every other month is too infrequent.<p>Personally I think the best way to make friends is at places where you might meet them in a context that gives you sufficient and regular 1:1 time. This is almost always school or work.</p>

<p>Often it stops there, that's what I mean. A big group of people to hang out with could give you the illusion of having friends when it's not really friendship, because it lacks the deep intimacy that comes with a good friendship.<p>There are more people LARPing as friends than are actually friends these days. Then I can see why many people reject "friendships" completely. Just dressing up and doing stuff with a few people is tedious unless it's mainly just about the thing you're doing (such as sports).</p>
