> They have demonstrated full self driving capabilities with a car driving "itself" to Taco Bell. I have a comma3 and have never had much success

I'm surprised you've even had any success. Are you a Comma Prime subscriber or something? Because mine absolutely gives no shits about red (or yellow!) lights, stop signs, "danger, sharp curve ahead," nothing. If it's the open road, lucky me. If there's the slightest decision to make, best to disengage

I'd say 2007 or so.

There wasn't any known active AI back then, but statistics on popular ideas and internet content was already a thing, and speech pollution based on those assessments had already started to spread fast, manually outputted.

Sure, a lot of good content came out since then. But the amount of garbage... it's immense and very difficult to sort out automatically.

The major issue is that this garbage then _became_ the norm. Only people who lived back then can remember what it was. For new folk, it looks just like a generational shift. However, it is quite obvious that some aspects of this shift were... unnatural (in the sense of not being spontaneous cultural manifestations).

White House communications director Steven Cheung reacted to the downgrade via a social media post, singling out Moody's economist, Mark Zandi, for criticism. He called Zandi a political opponent of Trump.

Show HN: Roast My Dish – AI roasts your food photos with brutal honesty
by romeumaleiane | 2025-05-17 01:14:48+00:00
Hey HN! I created a web app called Roast My Dish, it's a fun side project where you upload a photo of your dish, and an AI chef roasts it brutally. After the roast, it gives you a personalized "redemption" recipe to help you improve (or laugh).

It's built using Next.js, Tailwind.css, MongoDB, Azure Open Ai API, and I tried to mix entertainment with a bit of usefulness. Great for foodies, meme lovers, and anyone curious about AI + humor use cases.

Would love your feedback or ideas to improve it!

Don't confuse a polished TED talk from a practiced speaker with a seminar from any random person in academia. I'm sad to admit I've given talks (many recorded) that are much worse than this.

These seminar-style talks in particular have a strong Goodheart bias: academic scientists judge each other on the papers they write, but the highest honors usually come in the form of invited talks. The result is that everyone is scrambling to have their students give talks.

In larger scientific collaborations it can get a bit perverse: you want to get everyone together for discussions, but the institutes will only pay for travel if you give their students a 20 minute talk. You'll often have conferences where everyone crams into a room and listens to back-to-back 20 minute lectures for a week straight (sometimes split into multiple "parallel sessions"), and the only real questions are from a few senior people.

It's a net positive, of course: there's still some time around the lectures and even in 2025 there's no good replacement for face-to-face interaction. But I often wish more people could just go to conferences to discuss their work rather than "giving a talk" on it.

You can also use a microwave to bloom spices, or thaw frozen veggies from your home garden, or steam things, or thicken sauces, …

The microwave is a tool with certain useful aspects and certain limitations. It is also a tool which can lead to faster outcomes of things you need to do if the tool didn’t exist. At what point should a chef draw the line in the tools they use? Should I forgo microwaves? What about pressure cookers? Ovens? Surely knives are fair game? Maybe I should knap flint and butcher meat with it and cook over an open campfire — then truly no one can claim I am not a chef.

Yup.

Means testing is one of this things that fools people - it sounds good, but in practice is wildly bad at what it’s trying to do, and can be borderline evil.

Beyond the bureaucracy dimension - means testing puts up a barrier, not at the top, but everywhere.

Adding “one more thing” to people who are already struggling can be disproportionally difficult for them to meet, and therefore cause them to miss out on benefits they are completely entitled to.

Additionally, it can create incentives for behavior you would otherwise be completely pathological, such as divorcing your sick spouse because as a couple you don’t qualify for support, but individually they do.

> Any argument you can do one and not the other is insane.

Challenge accepted :).

The argument for lowering spending and lowering taxes is that the size of the economy and the tax base are inherently tied to tax rates and economic growth. Historically, federal tax receipts have hovered around 17 to 18% of GDP since the end of WWII, regardless of the tax rate[1]. Deep spending cuts paired with high taxes might increase the percentage, but it would be of a smaller economy, shrinking the overall tax base and making the debt ratio worse.

I don't know if that's true and I don't think we'll find out because the Republicans in Congress appear to be going for option C, lower taxes and larger deficits. The Democrats are in disarray and reflexively taking a contrary position, but even if they were in power I don't think this would be much of a priority. I think we get to see how far we can go. Maybe we'll beat Japan's debt to GDP ratio or maybe a failed auction or some debasement. The future has a lot of exciting possibilities.

Paying off the debt is cheaper (significantly so) than it was then, and we had no trouble then. So yes, if it didn't happen then it won't happen now, at least not for the same reason. You can construct a double/triple-failure situation, sure, but any argument of the form "We can't sustain this level of financing" is simply wrong by counterexample. We already did.

I don't really understand this take. You're unhappy because people are excited? May I ask, what do you work on and what do you get excited about that you'd rather advance? Do you think you're part of the group that is highly motivated and advancing ideas and people around them? Because I work with a lot of people in this group and this is the most exciting time I've experienced in my 30+ years. I am waking up and living and breathing this moment in time. I'm devouring more information than I ever have in my entire life, and it both feels like I can't get enough and that there's so much I'll never be able to keep up. So I really hope whatever you have in your pocket is just as interesting and excites people this much.

Is the cynical depression coming from watching people build your future without you while you're not a part of the conversation? Correct me if I'm wrong.

If "most of us" wish we'd hear less about LLMs how come it's always the hottest topic? That doesn't compute. Wouldn't have most of you taken over the conversation by now and changed the topic? Or perhaps whatever else you're trying to advance is just not that interesting to most of us?

I'm not a Rust guy and I probably won't be any time soon, but Rustls is such an exciting project in my eyes. Projects like BoringSSL are cool and noble in their intentions, but having something that's not just a hygienic codebase but an implicitly safer one feels deeply satisfying. I'm eagerly looking forward to this finding its way into production use cases.

> I'm not sure what you found in (checked) exceptions.

I could copy/paste the entire article here... but it would be easier if you could take a gander: https://mckoder.medium.com/the-achilles-heel-of-c-why-its-ex...

Summary:

Crashy code: You have no compiler-enforced way to know what exceptions might be thrown from a method or library.

More crashy code: If a method starts throwing a new exception, you might not realize you need to update your error handling.

Dead code: If a method stops throwing an exception, old catch blocks may linger, becoming dead code.

I think this is true, I've found I get roughly the same iteration speed for prompt processing no matter if the cache is fp16, q8 or q4.

It doesn't make sense to me though, I haven't looked into how it works inside but I would've thought it would pack vectors and then do 4-8b simd on all of them at once, but it really seems like it's not packing em.

If you know SQL, then yeah! But if you don't know SQL, using an AI to write a few queries & debug them is a great way to learn it.

I'm pretty comfortable with sql but still found it a fabulous tool recently. I have a sql database which describes a tree of some ~600k events. Each event is in a session (via session_id). Most events have a parent event - and trees of events can involve multiple sessions.

I wanted to add two derived columns to my events table. For each event, I wanted to name the root event for that event's tree and the root event within this session. I had code in typescript to do it - but unsurprisingly it was pretty slow. Well, it turns out you can write a recursive SQL query which can traverse the graph and populate those columns. I had no idea that was even possible.

ChatGPT managed it pretty well - though I ended up making a bunch of tweaks to the query it suggested to simplify it. I learned a bunch of SQL in the process - and that was cool! Obviously I could have read the SQL documentation and figured it out myself, but it was faster & easier using chatgpt. Writing SQL queries is a fantastic use case for LLMs.

They did ship hardware and software that wasn’t fully enabled. But your post implies there was some deception or extortion. System owners were well aware of what they paid for, or that they could upgrade and unlock some things. Today in software we just call it IAP.

I’m not saying it is how we -should-. But that IBM wasn’t rug pulling.

For example, I just asked o3 "how many Is are in antidisestablishmentarianism", and this was its train-of-thought output:

------

The user wants to know how many “I”s are in the word “antidisestablishmentarianism.” They probably mean the letter "I" in lowercase, though the question was a little broader with "Is."

I’ll treat it case-insensitively and count the total occurrences of the letter "i" (both uppercase and lowercase). I can count them manually now, or use a tool for faster analysis.

Analyzed word = "antidisestablishmentarianism" word_lower = word.lower() word_lower.count('i')

5 The user asked how many "I"s are in "antidisestablishmentarianism." I’m taking it to mean whether it’s counting "i" or "I", and I’ll consider them as the same for simplicity. So, I’ll count the 5 occurrences of "i" in the word. I manually broke it down and verified there are indeed five "i"s, so the final count should be 5. Pretty straightforward, now that it's all clear!

Done

There are 5 “i”s in “antidisestablishmentarianism.”

------

You can come up with complicated definitions of "core reasoning" where this doesn't count, and I understand there's great demand for such definitions, but this clearly satisfies common-sense understanding of the term.

I don’t expect a TED talk but we’re still talking about MIT here. I’ve seen 8 year olds more articulated. I guess where I am from being called in front of the class and having to present or talk about the homework reading is common, so perhaps why it’s seen as exotic in US to be able tie words together without saying “like” after every other word, or slump and touch the hair every 10 seconds.

I find that I like the errors from 1.12 to 1.14 the most. 1.12 shows where things happened during the expansion of macros, which can be useful, but 1.14 tends to be a bit terser and cleaner.

The newest errors tend to be noisy for my taste, and I have to tune out the advice to see the error.

Doing what?

Benchmarks aren’t all that useful since usually the bottleneck is File IO, external api calls, db calls, user latency or a combo of the 4.

Go’s main advantage in this matchup would be conciseness.

Go code looks so clean and nice, Java doesn’t.

I personally don’t care for Java, but I have bills so it’s always in my back pocket. Things happen , sometimes you need to write Java to eat.

“Fred, you really should just take the job.”

“Martha you don’t understand, it’s Java with an Oracle DB.”

I tried to find some use cases, this paper has listed some, although I think it's not obvious to me what makes the trees uniquely useful compared to other schemes (https://users.dcc.uchile.cl/~gnavarro/ps/cpm12.pdf seems to be the same Navarro as referenced in the article).

The use cases listed in that pdf are revolving around compression, e.g. graph adjacency list is listed as one. I myself found the last use case listed as smelling interesting (colored range queries), but I would need to dig into the references on that one to see what's actually going on with that one and is it truly anything interesting.

I would be interested in things like what's the unique advantage wavelets trees have compared to e.g. stuffing roaring bitmaps or other kinds of bitmaps into a tree. The RRR has rank-and-select queries which I think roaring bitmap won't do, so that might tie into something. Maybe a problem where the wavelet tree is the only known efficient way to solve it, or maybe it is uniquely really easy to throw at some types of problems or something else.

Anyone know real-world examples of wavelet trees used somewhere? I got interested enough to dig a bit deeper but on the spot as I'm writing this comment, I'm not smart enough to immediately see do these things have killer applications in any niches.

99% if not 100% of human thought and general output is derivative. Everything we create or do is based on something we've experienced or seen.

Try to think of an object that doesn't exist, and isn't based on anything you've ever seen before, a completely new object with no basis in our reality. It's impossible.

I genuinely love that 'rent just a room' (or even just a bed!) function of Airbnb, and continue to use it till this day. Have met many interesting people (or as I heard another comment on here say "weird in a non-dangerous way" lol), and it's always felt like a safe and quality experience to me (so long as I always do the due diligence and use common sense to stay with hosts that have tons of positive reviews, etc). IIRC Airbnb had a push a few 'releases' ago to revive this core part of their founding purpose, but now it seems they've moved on to 'services'.

> There's evidence to suggest players, particularly younger ones, are spending most of their time on these titles - sometimes referred to as "forever games".

There was a report the other day that cited something similar for games on iOS, they called it "evergreen titles". The games that are popular have a habit of staying popular.

But what the "forever games" and "evergreen titles" have in common is they cultivate habitual spending and extreme dopamine addiction, so their popularity might be being artificially propped-up by inadequate consumer protection laws in the first place.

> New hits took less time than ever to reach their first $1 million in revenue — 106 days — but competition from evergreen titles meant there were fewer of those standouts than before, according to Appfigures data.

This may be unpopular/counter-intuitive to say, but in a capitalist world this is probably the best outcome IF (and I'm not saying I can predict the future) we expect the profession to die/be obsolete from a society POV - in such a world restricting juniors before they commit a whole career to that profession and invest too much resources into it is actually the outcome we probably want. Better than the alternative of even more mass unemployment later. If that's the case then giving people that info early, and avoiding more hiring/training now stops potential mal-investment of money and people's time into training/hiring/building careers in/etc.

It stops juniors investing their life/time/energy in a field that is shrinking and that will increasingly "not be worth it" w.r.t effort put in given their longer time horizon. This is how capitalism when working correctly can obsolete jobs somewhat charitably - it does it by closing the door on entry level jobs ideally when people have little to lose and haven't yet invested a lot of their life into it. For example they may still be young enough to re-train; or may be dismayed from entering the field due to disruption/chatter and so do something more appropriate in the new world.

Being hired in a sinking and increasingly more competitive field may actually be considered a "winner's curse" outcome, in that you will be in a industry highly competitive that is slowly sinking and is stressful with low opportunities for pay rises compared to other industries/skill sets - this is definitely playing your career in "hard mode". Most of all you will feel your skills, and value is useless relatively to people who got into more jobs with more scarcity playing life in "easy mode" with less stress and anxiety. In a few years time people getting into other fields may feel they "dodged a bullet" comparing themselves to others that did.

Being able to pivot while you are still young and ageism isn't a barrier yet is definitely something to consider remembering careers these days are multi-decades long. I feel for your kid now, and I do for mine, but I would rather than try something different in their 20's vs say their 40's when they have a mortgage, a family to feed, and/or other commitments and ageism makes it harder to pivot/re-train into another career. I don't wish my kids to feel the anxiety I and many people I know are feeling later in life especially for a career that requires constant effort to maintain and keep relevant in. I'm not recommending my kids learn what I do at all for example.

Freedom of the individual is not compatible with communism. You can value some freedoms but all right to property is lost - something I value. (I don't allow freedom to murder - but I still value freedom more than communism can)

"“MCP is an open protocol that standardizes how applications provide context to LLMs, what’s the problem?”"

We are already off to a wrong start, context has a meaning specific to LLMs, everyone who works with LLMs knows what it means: the context is the text that is fed as input at runtime to LLM, including the current message (user prompt) as well as the previous messages and responses by the LLM.

So we don't need to read any further and we can ignore this article, and MCPs by extension, YAGNI

The problem with means-testing Social Security is that the government's promised some people "Social Security will be there for you" when they were in their 20's and 30's, and now you're taking it away in their 50's or 60's, when they can't go back and adjust life / retirement plans that were made taking into account "SS will be there for you."

In my humble opinion, this kind of broken promise borders on "the government defrauding the people".

It would be more legitimate to say "SS won't be there for you if you make too much" to those in their teens and 20's just entering the workforce -- but that won't have a major effect on cash outflow needed to satisfy SS obligations for 40-ish years (except for the small fraction of rich unfortunates who get SS because they become unable to work at a young age.)

You might also argue that the level of prying into people's finances implied by "means testing" is a form of illegitimate government overreach. If you believe this, in theory you should, for consistency, also believe that individual income tax ought to be eliminated (which many people consider a radical proposition).

> So because girls/women are finally given the same opportunities as boys/men and are excelling, the boys/men are miffed at this? The boys/men have the same opportunities as the girls/women. The fact they lag behind is their problem not the problem of the girls/women who are willing to work hard to achieve their goals.

There’s always too comments like this - people who clearly didn’t read the article but just have an idea of what the article might be about. I don’t understand why they bother subscribing.
