Show HN: I built an AI Agent to do Visual QA and Front end bug fixing
Hi HN! I am excited to share this new tool,
How it works:
1. Detects visual inconsistencies (misalignments, colors, spacing, typography, missing assets) between design mockups and developed UI.
2. Auto-generates Jira/Linear tickets, eliminating manual bug tracking.
3. AI fixes frontend bugs, creating GitHub PRs with clean code.
4. Browser Agent monitors live UI changes, preventing visual regressions in production.

With a VR headset: with Alyx, it's one of the best game I enjoyed playing :)

You ARE in space. That feeling when you hop in your spaceship, take off, point to the sky and come up in space...

Sure, after a hundred hours of playing, I came to the conclusion I had enough, I had seen everything that was to see in the game - even without completing it, never reached the center of the galaxy - but it sure was worth its price.
Correct, it's "arrival time".

It isn't uncommon to find german variable names in codebases that predate web 1.0 or linux.

Now that I think about it, german is especially good at creating words by concatination. So "arrival time" should just be the single word "Ankunftszeit" - "ankunftZeit" feels a bit off.
I think the general public has believed that self driving would arrive as some big bang moment where it just "worked" in 95%+ of environments where people drive. One morning there'd be an announcement it was cracked and then in six months you'd be able to buy a new car with it.

I don't think from either a business, technical or legal perspective google ever wants to sell or license their tech directly to a car being sold to the public.

They want to run a taxi service, they plan on running a taxi service, they're never going to sell it directly to consumers but they don't want consumers thinking about the implications of that.

They're just going to keep expanding Waymo in the background till it's ubiquitous.
I tend to agree with you, but had I been in Trump position I would do same - just freeze the bloody everything for 90 days and figure out in those 90 days whats actually important and whats not.

If I understand correctly, noone freezes things indefinitely
It's quite unlikely that OpenAI didn't break any TOS with all the data they used for training their models.
Not just OpenAI but all companies that are developing LLMs.

IMO, it would look bad for OpenAI to push strongly with this story, it would look like they're losing the technological edge and are now looking for other ways to make sure they remain on top.
I think it was termites. But they built a huge spaceship.

> Components often still use 0.1 inch pin spacing.

This changed with IC SMD packages. It's now mostly even 100-micrometers.

SMD passives seem to be in a state of limbo, but mostly still using inches. Mouser lists resistor size codes as both inch and mm. It's a bit confusing.
I think the 3D part is fine, it's more "all of physics" coming into play with a plane. Like bird strikes, engine failures, trying to decide how to handle that. What is the loss function the AI is supposed to apply if an emergency landing is needed?

And then if you have people flying the planes, you have to deal with people mostly _but not always_ doing the right thing. So now you build out a plan and have to deal with consequences of that.

So at the end of the day you're still looking at funneling humans into a thing. At worst you could consider ATC as "customer support", there to press buttons on machines to actually handle a bunch of logistics because the pilots need to figure things out.

On top of all of this, airports are trying to get through a lot of flights quickly. So people can make snap judgements about whether planes can or cannot advance, what they should do, etc. No matter how well your plan is, the instant a pilot mishears something it's over.

If we can figure out self-driving cars, maybe we can talk about replacing pilots with AIs. But in the meantime there's somebody not following the plan often enough.

This does lead to an interesting question for me, though: what is the biggest "human movement" system that is actually entirely hands-off logistics? I would imagine that postal service companies are doing a lot but every major person moving operation seems pretty hands-on from the outside.
What, are they unable to build a large-scale social network from scratch? Kids these days.

funny, I actually think the energy use was high not low. Like energy to move a 1000 KG thing for 100 meters just to answer a simple question? Try doing that with your own muscles.

And that from the system that is using like 10% of the energy then OpenAI. So for OpenAI every useless request is like pushing 1000KG for 1KM.
That was my thought exactly when I heard of this. I trust that like other major accidents, that we will learn from this and make the skies safer. Sixteen years without a major airline crash was an incredible accomplishment. It's a tragedy it couldn't have gone on longer.
> FWIW every time I've seen something that actually needs a "complex home brew codegen system", it's absolutely best expressed in a dedicated piece of software engineering and not within a macro environment. Zephyr leans heavily on that kind of engineering, actually.

I'd definitely agree with you about Zephyr's "I really want C macros to be real macros" system for it's device tree system. It's a huge pain to debug because you don't find issues until the linking step. However I'd counter with the fact that C macros _aren't_ real macros. Hence the pain.

Actually C's "macros" are literally just a separate codegen tool (m4 processor) just like what you're suggesting. It's a large part of what makes C code so hard to programmatically parse or automate.

Essentially Zephyr is doing meta-programming in an external codegen tool. Totally agree that a separate codegen tool specifically for device trees or whatnot could be better than that. However if C had a proper macro system (and compile time types), you could readily express the device tree system in the language at compile time and produce helpful errors.

> The point is really that "macros" is a weird sandwich between "complicated metaprogramming you need to do from first principles" and "you really didn't need metaprogramming, did you?". And that over the years that sandwich has been getting thinner.

They aren't really though. Homebrew codegen systems are much more of the weird sandwich between "you needed metaprogramming" and "you didn't have metaprogramming". Instead you build a system which is even more complicated in total, e.g. source and generated code gets out of sync, you have name clashes, the core API logic is spread out over different languages and code bases, etc.

Though I do agree the use cases for macros are shrinking, but more due to meta-programming via templates and compile time expressions becoming more powerful and usually preferable method to doing meta-programming.
Ask HN: Could Europe build their own AI infrastructure?
I wonder how Europe is set up for the coming AI race around the world.

What would happen if Europe were to be cut off from American supply of GPUs?

As far as I know, Europe has control over one company that is involved in the supply chain to build AI hardware: ASML. They build the lithography equipment which is needed to produce the wafers which are needed to produce the processors.

Are there companies around the world who can/could build this type of lithography equipment?

If Europe loses this piece of control over the AI supply chain, would Europe then be at the mercy of the USA for AI hardware supply? How long would it take for Europe to produce their own GPUs?
This is a great project.

It’s probably really early to ask, but in case anyone here is knowledgeable and has any idea: why didn’t TCAS help avoid the accident? Isn’t it designed for such situations where 2 aircrafts collide? Do military crafts not have it or something?
Right.

Helicopter was on Helicopter Route 4, per the map, apparently on course.

Aircraft was on approach to Runway 33, apparently on course.

That helicopter route crosses the approach to runway 33.

That's controlled airspace. How did they both have clearance to be there?

We'll know more tomorrow as all the audio and radar recordings are examined.
Or just open the simulator/charts on the capacitor manufacturer website and look at which capacitor filters which frequencies at which temperatures?

Apparently most EE's don't do this.. I've seen decoupling caps in designs that basically do nothing.
I can't help but feel this is reintroducing some of the problems it claims to solve in working around the difficulties.

* The fact that there is an `Oom` error that can be thrown means that there is no increase in reliability: you still don't know how much memory you're going to need, but now you have the added problem of asking the user for how much memory you're going to be using — which they are going to be guessing blindly on!

* This is because the memory usage is not much more predictable than it would be in easy mode Rust. (Also that "mem.lem()/2" scratch space is kind of crappy; if you're going to do this, do it well. Perhaps in allocating the correct amount of scratch space, you end up with a dynamic allocator at the end of your memory. Does that sound like stack space at the start of memory and heap space at the end of memory? Yes, your programming language does that for you already, but built-in instead of bolted-on.)

* Furthermore, the "easy mode" code uses lots of Box, but if you want you can get the benefits of RAII without all the boxes by allocating owned vectors scrupulously. Then you get the benefit of an ownership tracking system in the language's typesystem without having to `unsafe` your way to a half reimplementation of the same. You can get your performance without most of the mess.

* Spaghetti can be avoided (if you so desire) in the same way as the previous point.

What you do achieve is that at least you can test that Oom condition. Perhaps what you actually want is an allocator that allows for simulating a particular max heap size.
Do you think that blockchain engineers are incapable of developing high throughout distributed systems due to engineering incapacity or due to real limits to how fast a strongly consistent, sufficiently secured cryptographic distributed system can be? Are blockchain devs all just idiots, or have they dumbly prioritized data integrity because that doesn't matter it's about big data these days, nobody needs CAP?

Gravitational Waves: Even though both light and gravitational waves were generated by this event, and they both travel at the same speed, the gravitational waves stopped arriving 1.7 seconds before the first light was seen ( https://bigthink.com/starts-with-a-bang/light-gravitational-... )

But people don't do computation with gravitational waves.
Mass is relative to speed. If the object has a very high speed, it can reach the mass of the earth or even higher. That's why my understanding is that if it can escape the gravity of the earth, it means its own gravitational field is as or more powerful.
More detail to come. You're right, it's unprecedented.

A lot would probably be loan words anyway, and they're words many English speakers would also need to learn. Array, socket, database, loop, float, function, etc.

If the stack overflow examples are in English, you might as well use it. That's also why JavaScript is maybe a better choice than Typescript even if Typescript is better.

Are you suggesting it's easier to successfully sue OpenAI for copyright infringement if you live in China?
Doesn't mean generative models won't make it worse. Sure, maybe the advice given to you by an influencer in a short video was bunk, but at least you could be sure that they actually said it. Soon you won't be certain even of that.
Do you seriously hallucinate a difference there? I'd like to have what you're smoking.
You're not replying to the original poster. It's a different commenter.
Too low, most likely.
How much data from o1 would DeepSeek actually need to actually make any improvements with it?
I also assume they'd have to ask a very specific pattern of questions, is this even possible without OpenAI figuring out what's going on

Ok, the question is: how to get a PERSONAL .arpa domain? (i want one too :D)
The real question, I feel, is whether the current U.S. government as it exists in 2025 is still capable of continuing to improve things, and whether it's still putting all the lessons of the past into practice - or whether we were just coasting on a combination of luck and the vestigial safety left to us by the diligence of the past.
I should be flattered you wasted some time looking into my history, but let me disappoint you here - I am sympathetic to truth alone. Russian, China or the US do not matter much to me. Visiting/living in those countries is absolutely horrible experience, which I am lucky to have very little of (with exception of some regions in China perhaps).

My interest in US politics is based on pure curiosity. And on top of that, it's very unfortunate that US spreads it's "interests" everywhere in the world, starting wars, overthrowing governments and sorts. So no matter where one lives or planning to, it's going to be interesting and relatable.

If we take this particular case, my welcome to the measure is partially based on hope it will help to deescalate and eventually stop the Ukraine war - useless meat grinder and money laundering machine for corrupted politicians.

And if it makes my posts "inflammatory" - I will humbly welcome that as well.
They're not actually processing the entire system prompt (which is rather long) on every query, but continuing from a model state saved after processing the system prompt once.

That makes it a bit harder, but still, spitting out the wrong date just seems like a plain old time-zone bug.

Using the phrase "virtue signaling" as a pejorative is iniquity signaling.

In reality, it serves an important social function. Expressing ethical values signals to others that these values matter and encourages collective action. When enough people make similar choices, it can create economic and social pressure for change. Publicly aligning one's actions with one's principles isn't just about image. It's about fostering accountability, strengthening community values, and inspiring others to reflect on their own choices.

In this way, "virtue signaling" can be a catalyst for meaningful social and economic reform.
Voluntary coordination and shared purpose are great things.

Otherwise, all the “forward” and “shared purpose” euphemisms do not change the fact that you have a tyrannical system, nor do the “intellectually lazy” ad hominems.
> reproduce the OpenAI capabilities from scratch

who cares. even if the claim is true, does that make the open source model less attractive?

in fact, it implies that there is no moat in this game. openai can no longer maintain its stupid valuation, as other companies can just scrape its output and build better models at much lower costs.

everything points to the exact same end result - DeepSeek democratized AI, OpenAI's old business model is dead.
I read this and think that if they see DeepSeek as a threat to national security due to sending personal data to another country, then isn't any US-hosted good LLM a threat to any other country?
Maybe they use AI to monitor traffic, but it is still learning :)
No I worked at Sears and it was driven into the ground by an idiot PE fund manager and his arrogant consultants.

Sears had one big problem when Eddie took over: it was out of step with the then-current retail format (big box stores). Its stores were heavily situated in enclosed malls that were out of fashion. The solution was straightforward if expensive: reformat the business (Sears had already done this twice before).

But then Eddie rolled into town with his genius consultants and a galaxy brained idea: Kmart has stand-alone stores that kinda look like big box if you squint. So let's just merge the brands together! Then Sears ends up in big boxes without expensive reformatting!

The fact that the brands were completely incompatible was pointed out by everyone who knew anything, but those weren't people in Eddie's inner circle so their opinions meant nothing.

By the way I don't think ESL Investments ended up making money on Sears. They stripped the company of assets yes, but most of those assets were distressed by the collapse of Sears. Like a lot of real estate was in struggling malls that had Sears as the anchor tenant. ISTR some of ESL's LPs suing Eddie.

Eddie made money the way all PE fund managers make money even when everyone else involved loses their shirt: by charging fees.
In Germany I've seen both. Whenever possible I push for having everything in English. Code comments, general documentation, databases, etc simply because the german developers know English but the non-german developers sometimes don't know German. It also puts everyone at roughly the same language level since we don't have many English natives.

PS: I remember quite a while back when Wargaming's World of Tanks became a big thing they had to translate everything from Russian to English because they wanted to get foreign developers involved as well. Never heard of the reverse happening.
I've been thinking about this.

In self driving world it no longer makes sense for a car to look like they do now.

Instead I think they operate a bit like Coach and Horses used to. You the consumer own the "coach", you have it specced out how you want it, your choice of seating (hell even a bed?), your sound system, your big screen tv, whatever you want because you're a passenger not the driver.

The "horses" are the self driving bit + batteries. The ubiquitous taxi service owns these. Maybe you permanently rent a low range model (100 miles) that is attached to your "Coach" at all times for quick errands. For longer range journeys you hire a model with more battery and longer range that drives over and attaches automatically to your coach.

For really long range journeys, your self driving "horse" drives into a coaching station along the way, detaches and another one attaches in 30 seconds and off you go.
Edge detection is used a lot in 2d & 3d graphics, microscopy, telescopy, photography, and a ton of other fields.

If this could be done almost instantaneously and without additional energy, it would be very useful.

I can imagine having tiny analogue edge detection component in cameras, microscopes, telescopes, and maybe even graphics cards.

This could be a part of the future of computing - tiny specialized analogue components for specific tasks.

On the other hand, maybe digital compute, whether silicone or futuristic alternatives, will always be cheap enough that the economics will never work out - it'll always just be cheaper to throw more general purpose compute at a problem.

Maybe. The article talks about "how the Obama-era FAA practiced discrimination in its hiring processes," which wouldn't apply to the woman I know. But it's not an in-depth article so it is possible such practices were still in place through Trump's first term and post-COVID when FAA hiring ramped up and would have affected the person I know.
