Reminds me when I was demonstrating Claude code to a friend recently. My friend was a huge cursor user and was just curious about the cli tool and stuff.

In the end, regardless of framework or approach, I believe there is a way to go about using llms that will optimize work for developers. I worked with this tech lead who reviews all PRs and insists on imports arranged in a specific order. I found it insulting but did it anyway. Now I don’t - the not does.

The same way that llms can be really helpful in planning and building out specific things like rest endpoints, small web components, single functions or classes and so on.

Glad people are attempting to work on such potential solution for approaching work to take advantage of these new tools

This is a nice article. I'm trying to make a map save file format. I'm curious if most developers usually use abstractions over bitflags(safely hiding away the bitwise operators from being typod, etc). My main niggle is I want maximum type safety and compile time checking, ie the compiler preventing me from accessing a bit that isn't being used or mixing things up. My other concern is also backwards compatibility if I want to modify the flags. Saving 2 bits for the version?

I want a kind of tree structure of bitflag values, and I'm trying to think of a good way to do it. For example a Grass /Stone tile, maybe 4 bits for the tile type (0001 = Grass), and then from that point forward, the remaining flags depend on the tile type (Grass having the next 2 bits for the grass colour, stone having 1 bit for whether it's cracked or not, etc), but in a safe and efficient abstraction where I can't accidentally mix them up. I don't want a pirate software monstrosity where I can't keep track of the different combinations.

996 or worse is what got us the labour movement in the first place. In a well regulated industry the practice is illegal or carries explicit expectations of overtime, time off, or both.

For evil-aligned founders it's important to realize that exploiting workers is one of the best trod paths to success. If you can get away with it without causing a revolt you're almost certainly getting more for your money. So being up front with 996 is absolutely in your interests. Being hard-core, 10x, cracked (pick your generation's euphemism) is just good marketing. Be prepared to cut anyone who burns out, try to get people without any ties or those who can't afford to quit. Maybe even create a cult of personality around yourself.

> let a: Double = -(1 + 2) + -(3 + 4) + -(5)

> Still fails on a very recent version of Swift, Swift 6.1.2, if my test works.

FWIW, the situation with this expression (and others like it) has improved recently:

- 6.1 fails to type check in ~4 seconds

- 6.2 fails to type check in ~2 seconds (still bad obviously, but it's doing the same amount of work in less time)

- latest main successfully type checks in 7ms. That's still a bit too slow though, IMO. (edit: it's just first-time deserialization overhead; if you duplicate the expression multiple times, subsequent instances type check in <1ms).

I'm wary rather than skeptical I think. There's clearly value here. Whether we're paying the true costs or not, however, won't be clear until all the VC fumes have cleared.

Much like the internet era actually - obviously loads of value, but picking out the pets.coms from the amazon.coms ... well, it wasn't clear at the time which was which; probably both really (we buy our petfood online) except that only one of them had the cash reserves to make it past the dot com crash.

I honestly think Tesla is past the point where lidar would provide significant benefits. I've tried FSD for a month or two and it can see everything but just drives like an idiot. Lidar isn't going to help it merge properly, change lanes smoothly, take left turns at lights without blocking traffic, etc.

Check out what the Tesla park assist visualization shows now. It's vision based and shows a 3D recreation of the world around the car. You can pan around to see what's there and how far away it is. It's fun to play around with in drive thrus, garages, etc. just to see what it sees.

Yep, completely agree.

I got in a bit of a disagreement with teammates at a previous job. I liked these teammates, they were very smart and nice people, but for a specific project I wanted to use LMAX Disruptor, and the excuse for not using it was very literally “we don’t want to make people learn anything”.

That stuff blows my mind; aren’t we engineers? If we’re not willing to learn new things and adapt, what exactly are we offering that a high school kid who bought an “Intro to Java” and “Intro to Spring” book can’t?

People really shouldn’t read too much into these numbers, particularly in that kind of forum rather than an analyst call. Is M&A an investment? What about hiring a team with stock? Commitment or actually transacted? As cash, equity, debt? Other than the sheer orders of magnitude being bandied around, and that being an indicator of the kind of phase we’re in right now.

Why would 30 minutes by car become 1.30 hours by public transport.

My (European) experience is the opposite: it takes longer to go to work by car, you're sitting in traffic whereas subways and trains take a fraction of the time as they are not impacted at all.

I live in Rome, which isn't known for great public transport. Yet I've seen multiple times people going from Rome suburbs to Naples downtown (a completely different region, 150 miles away) than it took me by car to do 7 miles.

Where are you driving?! If the person you're replying to has gone 8 months in Boston without having to intervene, I'm impressed. Boston is the craziest place to drive that I've ever driven.

Pro tip if you get stuck in a warren of tiny little back streets in the area. Latch on to the back of a cab; they're generally on their way to a major road to get their fare where they're going and they usually know a good way to get to one. I've pulled this trick multiple times around city hall, Government Center, the old state house, etc.

I cannot understate how afraid I am of the use of AI Surveillance. The worst thing is there is nothing you can do about it. It does not matter how private I am online, if the person I am sending things to is not privacy conscious and, say, uses AI to summarize emails, then I am in the AI database. And then there is just the day to day data being scraped, like bank records, etc.

I mean a PARKING LOT in my town is using AI cameras to track and bill people in a parking lot! The people of my town are putting pressure on the parking lot owner to get rid of it but apparently the company is paying him too much money for having it in his lot.

Like the old video says "Don't talk to the Police" [1], but now we have to expand it to say "Don't Do Anything", because everything you do is being fed into a database that can possibly be searched.

I don't hate Tesla. I've owned two of them, and still have one. I just think severe underperformance and hallucinations are going on with the company.

FSD has been a complete lie since the beginning. Any reasonable person who followed the saga (and the name "FSD") can tell you that. It was mobileye in 2015-2016, which worked quite well for what it's, followed by unfilled "FSD next year" promise since then every year.

People believe what they want. Ergo they side with the people who state that those beliefs are true, makes them feel good. Listening to experts who know better and oppose the held beliefs makes the believers feel bad, ergo they won't believe them.

Sometimes it is good to disregard the opinion of experts who are absolutely sure something can't be done, might by a prerequisite to making it happen.

The four minute mile comes to mind.

Beliefs are powerful, they can enable you to reach goals, become prisons of the mind trapping you or become delusions when feedback is disregarded.

> I thought it was precedentual within its circuit until an appellate says otherwise?

No, trial court decisions are never binding precedent, if they are “published” decisions, they may generally be cited as persuasive precedent. Appellate decisions (Circuit Courts in the federal system) are binding on the trial courts subordinate to that appellate court (and even on panels of the same appellate court) until reversed by the same court sitting en banc or by a higher court (the US Supreme Court in the federal system.)
Show HN: Dumb Site to Rate Horses

I wanted a project to learn the Dioxus framework. It needed to be relatively simple and fun. Here is a site that lets you rate horses.

The horse people I know have taken issue with this site because they say all horses are beautiful. What do you think?

Images are from an open source AI training dataset of horses, so there are some odd ones in there...

> NEMA 14-50 , aka dryer outlet

The reason why I was asking for the outlet is precisely because "dryer outlet" can mean a lot of different things. Dryers in the US usually don't even come with cords out of the box because people may have a few different plugs. Does it have a neutral? Is it 30A or 50A? All possibilities for a "dryer outlet".

I was reminiscing in a comment about the dot com era earlier - it occurs to me that this little documentary gem might have passed by some of the HN crowd at the time or (gulp) been made before they were born.

It's a pretty great perspective on what tech startup life was like back then. I'm going to re-watch it later.

If anyone is looking for other (even earlier) media on the topic you could try to dig out the book "Burn Rate" about a multimedia (think CD ROM) based startup.

"We hear them everywhere— their bad ideas, their grievances are all amplified."

Bridget Todd discusses these guys with her guest Anil Dash on the latest episode of her pod "There Are No Girls on the Internet", if anyone is interested. Dash thinks that they simply don't love tech. I also think that their bizarre world views contributes to the shit show the mainstream Internet has become.

For the rest of us, as long as net neutrality is operative we can at least experiment with alternatives. But that is already in the crosshairs. It reminds me of the history of radio. The airwaves used to be public. Now you're lucky if you can get--and keep--a community FM station on the air.

In RLVR? Quite easily.

And OpenAI has induced hallucinations in o3 with RLVR mistakes, not with a failed pre-training run. They used o4-mini as an example - similar training to o3 and similar issues.

Conversely, they have also designed a post-training system that has successfully reduced hallucinations in GPT-5.

Oh please - people excuse and dismiss major accomplishments, you can send a skyscraper to mars and people on HN will still be calling you a fraud.

The Bay Area has massive traffic, complex interchanges, SF has tight difficult roads with heavy fog. Sometimes there’s heavy rain on 280. 17 is also non trivial.

What Tesla has done is not trivial and roads outside the bay are often easier.

People can ignore this to serve their own petty cognitive bias, but others reading their comments should go look at it for themselves.

Whats the oddest thing about the wiper tech is that we've had the tech for automated wipers since at least the 70s. As a kid my neighbor's Cadillac had it.

tl;dr: you can use optics to determine if there's rain on a surface, from below, without having to use any fancy cameras or anything, just a light source and light sensor.

If you're into this sort of thing, you can buy these sensors and use them as a rain sensor, either as binary "yes its rained" or as a tipping bucket replacement: https://rainsensors.com

> Not a love letter or a sermon or a story, but a receipt. This probably reflects their ubiquity rather than importance.

We humans are pretty good at remembering sermons and stories and we can recreate them from memory and pass them down to the next generations. We however suck at remembering numbers, that's why we invented writing so we could write the numbers down and rely on these records, instead of on bad human memory.

It's a tough thing, I'm a solo dev supporting ~all at high quality. I cannot imagine using anything other than $X[1] at the leading edge. Why not have the very best?

Karpathy elides he is an individual. We expect to find a distribution of individuals, such that a nontrivial # of them are fine with 5-10% off the leading edge performance. Why? At least for free as in beer. At most, concerns about connectivity, IP rights, and so on.

Well, it's more like sensor fusion plus extensive human remote intervention, it seems: https://www.nytimes.com/interactive/2024/09/03/technology/zo... . Mind you, if it takes both LiDAR and call-centre workers to make self-driving work in 2025 and for the foreseeable future, that makes Tesla's old ambition to achieve it with neither look all the more hopeless.

It's nice to see people putting effort into tackling things from the human side outside of phishing awareness campaigns and annual training. Even CrowdStrike noted in their annual report that something like 70% of successful attacks were interactive intrusions without malware.

The only "metacognitive" skill it needs is to know how many D there are in every token, and sum those up. Humans are great at that sort of skill, which is why they can answer that sort of question even in languages where each letter is a group of sounds and not just one like Japanese katakana, that is not hard at all.

LLM are also really great at this skill when there is ample data for it. There is not a lot of data for "how many D in DEEPSEEK", so they fail that.

A company touting its 996 culture is unfurling a huge red flag that it doesn't have the best talent. The very best companies/workers accomplish extraordinary things in ordinary working hours, because they are extremely good at what they do and thus extremely efficient at it. Work smarter, not harder, as they say. If a company needs to work 996, it simply means it isn't all that smart.

One of the shower thoughts I've had is why don't we start equipping cars with UWB tech. UWB can identify itself, two UWB nodes can measure short range distances between each other (around 30m) with fairly decent accuracy and directionality.

Sure, it wouldn't replace any other sensing tech, but if my car has UWB and another car has UWB, they can telegraph where they are and what their intentions are a lot faster and in a "cleaner" manner than using a camera to watch the rear indicator for illumination

Honestly wondering if this is a legit use of DMCA. Like, what exact provision of the DMCA is being implicated here?

One should have some reasonable means for challenging this kind of thing. But what do I know.

It’s a scary world when you know a C&D or other legal nastygram is 100% bullshit and want to ignore it, but you’re chained to a vendor that can’t respond with any level of subtlety, just the ban-hammer for everyone

So the C&Ds and nastygrams become increasingly ridiculous, but whatevs, they’re all rubber-stamped so hey corporate just push that red “lawyer” button and make my embarrassment go away real fast, before any Streisand effect can kick in!

On the one hand, buybacks do allow a company in decline to paper over their failings. The post discusses that kind of thing.

On the other hand, a private company provides more actual value to the public than a public company. Public companies suffer from investor capture and face enormous pressure to think short term. So they 'enshittify' (to use the author's word). So, in theory, buying back shares is a step in the right direction.

Those two aspects have been banging around my head for some time, and I'm still unsure how to reconcile them.

> To educate people you just need the internet (communication infrastructure).

This is laughably reductive. Certainly the Internet can help people get educated and pop some comfort bubbles, but it's not automatic. Many (most?) humans need personal attention from others to learn. Even fewer place a value on what they're taught, much less learning itself. A significant number of people must have supervision and some proding to become functioning, literate, and informed adults.

All that said, I'd agree with most of your other points.

So they are all burying the lede it isn't about the innocent casualties that so much as the side they belong to.

> how often? as practiced by who, and where?

This was my experience in Google Search infrastructure circa 2005-2010. This was a system with dozens of teams and hundreds of developers all pushing their data through a common message bus.

It happened all the damned time and caused multiple real outages (from overzealous validation), along with a lot of tech debt involving having to initialize fields with dummy data because they weren't used anymore but still required.

Reports from other large teams at google, e.g. gmail, indicated they had the same problems.

> Nice, "explain to me how you're going to implement a backward-compatible SUM in the spec-parser that doesn't have the notions needed. Ha! You can't! Told you so!"

Sure sure, we could expand the type system to support some way of adding a new tag to every element of the repeated oneof, implement it, teach everyone how that works, etc.

Or we could just tell people to wrap the thing in a `message`. It works fine already, and everyone already understands how to do it. No new cognitive load is created, and no time is wasted chasing theoretical purity that provides no actual real-world benefit.
Show HN: Evalyze – AI investor matching from your pitch deck (feedback welcome)
by Veefa | 2025-09-06 17:40:20+00:00
I used to work in VC and watched good teams lose months chasing the wrong investors. I’m building Evalyze to make the unglamorous parts faster and more precise.

After sign-up (email only, no card) you can:

- upload a deck or paste your site - get a ranked list of relevant VCs/angels with a short “why” for each

What’s different: instead of dumping a big list, we try to explain why an investor fits based on stage, sector, check size, and portfolio patterns. It’s far from perfect and we want blunt feedback before opening wider.

Limits to know:

- newer funds and emerging managers can be underrepresented - geo nuances are still rough - matching can over-weight buzzwords if the deck is vague

I’d love critique on the ranking logic, signals you’d add/remove, and any privacy concerns. If you don’t want to upload a deck, there’s a sample you can use to see the flow.

I’ll be here replying and shipping fixes as comments come in.

The craziest thing I've discovered is that unattended-upgrades does not timeout after failing to download pkgs from security.ubuntu.com AND will NEVER release "dpkg/lock-frontend". It will happily keep failing to download new pkgs, NEVER printing any error messages that I could see to the journal or a log file ("/var/log/unattended-upgrades"), and preventing the user from using apt because it holds a lock that it refuses to give up.

The process doesn't even respond to "systemctl stop unattended-upgrades" or SIGTERM. Only "kill -9" ends the titan grip it has over my systems.

Edit:

Out of curiosity I ran a packet capture, during the 8 minutes it was running, unattended-upgrades (apt) received 4MB and sent 182KB of packets. Given the unattended-upgrades package is installed by default on Ubuntu and the "apt-daily-upgrade" timer will run every 24 hours ((archive|security).ubuntu.com has being down for longer), I can only imagine that there must be millions of machines reaching out, repeatedly and uselessly, attempting to download new pkgs without any timeout over and over again.

While I agree with your take on the harms or AI surveillance, I will never agree that AI is beneficial, and there is a net negative outcome using AI. For example electricity prices, carbon release, hallucinations, cognitive decay...they all outweigh what benefit AI brings, which still is not clear.

Like nuclear fission, AI should never have been developed.

In the standard system for libraries, the book is paid once.

That is "libraries" as in "we have societally decided to make published knowledge freely available".

Societies have not decided that window washing should be freely available - on the other side, they have decided that published knowledge be freely available (that is the meaning of the establishment of libraries).

Amazing that someone so acclaimed can write something so foolish. Buybacks can be good, buybacks can also be bad, like any other financial management decision. The same buyback can be good for some people, and less advantageous for others.

Instead of labeling it “Trump oligarchy shit” (?) just don’t own shares of whatever company you are upset about.

This guy clearly just has a bone to pick.
