Shere are so many levels this could be answered at.

All light in a narrow cone extending from the camera gets recorded to one pixel, entirely independently from other pixels. There's no reason this would be blurry. Blur is an artifact created by lenses when multiple pixels interact.

There is a lens in the apparatus, which is used to project the image from the mirror onto the pinhole, but it is configured so the plane of the laser is in focus at the pinhole.

What I don't understand is how the projection remains in focus as the mirror sweeps to the side, but perhaps the change in focus is so small.

> I think Claude Code itself is mostly vibe coded

What definition of "vibe coding" are you using here? I seriously doubt Claude Code was made "mostly" (or even "partly") by telling a prompt what they want, and accepting the output when it looks functionally acceptable without regard to how the code looks or works under the hood.

... Which is what "vibecoding" is.

Vibecoding != AI assisted/agentic coding

> That's an eternity for a request. I highly doubt they will timeout any model they serve.

That's what easing functions are for.

Let's say 10 GPUs are in use. You keep another 3 with the model loaded. If demand increases slowly you slowly increase your headroom. If demand increases rapidly, you also increase rapidly.

The correct way to do this is more complicated and you should model based on your usage history, but if you have sufficient headroom then very few should be left idle. Remember that these models do requests in batches.

If they don't timeout models, they're throwing money down the drain. Though that wouldn't be uncommon.

I have a lot of devices and have an app that supports a lot of device types. FireWire (like Thunderbolt) means daisy chaining those devices with a single port on the host. With USB I need hubs which need external power and may or may not work at full speed with different cables and all devices need cables long enough to go back to the host or hub.

If you blow the cable apart at a few important points the mass that falls either hits fairly near downrange from the tether, or does not hit at all. Have a group of range safety officers for the charges and a law that when on duty they are expected to shoot any politician that contacts them. (I'm thinking of Fukushima. We need to vent the reactor or it will blow! You can't vent until the city has been evacuated. The reactor didn't listen to the politicians.)

It was Diwali vacation in India. It looks like the managers were not able to force everyone to walk around with their laptops and pagers hanging from their necks and waists, respectively, which they normally do.

If there's one thing I have learned from my Amazon mates, then that is they never have a true time off. Hills, beaches, a marriage in the family— no exceptions. It's so pervasive that I can't really imagine it to be voluntary, and my friends' answers on this topic have never been clear.

I think it’s actually a pretty good comment. Most people would not know that skin and food exposure are different. This is something you are told as a parent though. E.g. My daughter had a skin reaction to (chicken) eggs at week 29 but tolerates them just fine as food and we were not particularly concerned but if no one had told us I would have thought it was a problem.

For a service like AWS, 75 mins is going to result in a LOT of COE's for people on way it wasn't mitigated quicker. A Sev 1 like this has an SLA of 20 mins to mitigate impact. Writing about these failures will consume a dozen peoples time for the next 6 weeks.

I have 10 years of experience at Amazon as an L6/L7 SDM, across 4 teams (Games, logistics, Alexa, Prime video). I have also been on a team that caused a sev 1 in the past.

Author here, I think we're mostly in agreement. Unlisted is a great approach for usability, especially for content with low sensitivity. It's a risk versus effort thing.

I'll point out that users don't always have a perfect understanding of the security websites provide. I'm a fan of Krug's book, Don't Make Me Think, as a model for how users interact with website UI and I think that's often how users interact with security. If you expect users to read, understand, and retain technical information you're going to be disappointed.

For YouTube in particular I noticed a number of articles that explain how unlisted content can leak and how to recover from a leak, so I think the 'may' in the quote is quite correct.

Oh no.

I suppose it is something to do with the fact that it has been, what, almost 40 years since the lectures?

The fact that most of the code would still work is a miracle. That wouldn't work for, say, Java (which didn't exist in 1986). Nor C++. Nor Javascript (also not there back then). Fortran and C might be able to pull it off (but barely).

Remember, we didn't have computers worth the name back then. Shoot, we didn't even have dirt yet, just rocks.

Do you mind providing sources for that?

Because, as a EU citizen, I have never in my life seen any tests that carmarkers are advertising with that focus on pedestrians. I am regularly seeing tests that focus on occupants though, e.g. the Euro NCAP. But I am by no means an expert.

It would be hard to focus on pedestrian safety from a carmaker standpoint except for adding software features that recognize people in front of you and auto-brake or smth, which definitely is not the focus of the tests here. It may be a requirement though. The more I think about it, the more sure I am that you just made this up, sorry.

""It's always DNS" is a long-standing sysadmin saw, and with good reason: a disproportionate number of outages are at their heart DNS issues. And so today, as AWS is still repairing its downed cloud as this article goes to press, it becomes clear that the culprit is once again DNS. "

I use stored DNS data.^1 The data is collected periodically and stored permanently

I seem to be unaffected by DNS-based outages

I use stored data because it is faster, e.g., faster than using DNS caches like Google DNS, Cloudflare DNS, etc., but there are obviously other other benefits

1. When I make HTTP requests there is no corresponding remote DNS query. The IP address is stored in the memory of the localhost-bound forward proxy

Right, and where are all those LLMs without the billions upon billions of lines of text written by humans? A not insignificant number coming from Wikipedia?

Also, LLMs don't produce truth. They don't have a concept of it. Or lies for that matter. If you are using LLMs do study something you know nothing about the information provided by them is as good as useless if you don't verify it with external sources written by a person. Wikipedia isn't perfect, nothing is, but I trust their model a shitload more then an LLM.

Fair enough, but in my estimation that next big thing is gene therapy, and the best way to get involved with it is to become a medical geneticist.

I'm sorry to be a buzzkill, but I just can't get excited about privately-funded space rockets or Japanese girlfriend robots, not even if there were an 8 figure stock compensation package in it for me. To me, it's all just "do something grandiose for the venture capitalist bucks, and then maybe figure out how it helps people in 20 years."

That's the best answer. Just wondering because you have a lot of experience and many people disagree with me.

How realistic is a C++ compiler that's 50x faster than clang for debug builds? Assuming 1) there's enough work for each core 2) there's so many files/headers that a unity build takes 1/4th of the time as a rebuild using individual files (this theoretical compiler would be multi-threaded)

I went to a school that was heavy on immigrants and had lots of 1st gen citizens as students and all they did was advocate against people like me for admissions and for preferential admissions for their own group. So in my opinion, skilled immigration is not a transfer of talent but an expansion of the upper classes who go to war with each other over a small number of seats. Ironically this zero sum game keeps overall skill levels the same. For every immigrant, say, one citizen loses a seat somewhere.

The US is allied with actual authoritarian regimes.

I'm not a big fan of the UK, I grew up there and left. But this whole UK is authoritarian thing is totally overblown in the US media and HN comments. Having free speech restrictions implemented by an elected government isn't authoritarian. You could even say that having totally free speech imposed by a non-elected government is authoritarian if people don't want it. These things are separate. I listen to UK media quite often (topical comedies mostly) and my feeling is that these laws are generally supported. There's a lot of negativity about social media from bullying up to incitement of violence.

Yup, it's not like a video game where you get instant notification/identification.

And it's why we have been so worried about Russian nukes--they have used liquid fueled birds, they can't be held ready to launch. Such birds are pretty much only useful for a first strike as they won't be able to launch them once incoming missiles are detected unless they're being held at launch ready (and they can't do that for too long.)

It's quite country dependent. For example in Hungary my understanding is that many doctors have both private and public practices, but private clinics often don't have expensive machines. Doctors in public hospitals are severely underpaid so they have strong incentives to move you to private practice.

In Italy doctors also have public and private roles but can practice privately in public hospitals, which is weird but was an attempt to avoid losing them to private clinics, for the same reason. You also have private clinics administering public healthcare with a minor markup paid by the patient, and the base rate paid by the state, which isn't a thing in Hungary for example.

It is in general for non-life threatening conditions that there's such competition tho, I agree.

There was a period of a few decades (I guess still ongoing, really) where parents sheltered their kids from everything. Playing in the dirt, peanuts, other allergens. It seems like all it's done is make people more vulnerable as adults. People assume babies are super fragile and delicate, and in many ways they are, but they also bounce back quickly.

Maybe part of it is a consequence of the risks of honey, which can actually spawn camp infants with botulism. But it seems that fear spread to everything.

I did something similar: made an LLM generate a list of "blockers" per transcribed customer call, calculated the blockers' embeddings, and clustered them.

The OP has 6k labels and discusses time + cost, but what I found is:

- a small, good enough locally hosted embedding model can be faster than OpenAI's embedding models (provided you have a fast GPU available), and it doesn't cost anything

- for just 6k labels you don't need Pinecone at all, with Python it took me like a couple of seconds to do all calculations in memory

For classification + embedding you can use locally hosted models, it's not a particularly complex task that requires huge models or huge GPUs. If you plan to do such classification tasks regularly, you can make a one-time investment (buy a GPU) and then you'll be able to run many experiments with your data without having to think about costs anymore.

Your source itself says the numbers are not directly comparable because of different measures of homelessness, and the US is widely reckoned to undercount: https://www.opportunitynowsv.org/blog/invisible-people-regio...

Nevertheless, medical debt is a significant driver of homelessness in the US, while it is not one in the EU.

Helping me get up to speed with an unfamiliar API much, much faster than any online searching.

I can describe an example application and see which API is chosen, along with which functions/methods are called and in what order and with what data structures.

I take it from there and build on that by hand. Take Python UI development, for example. I can ask for a window with a zoomable bitmap image with scrollbars. I get an answer I can refer to in seconds. If I know that I want PySide6 or PyQt6, I can specify that, or I can ask for a list of Python UI APIs and their strengths/weaknesses.

Hyperbole.

I am not going to avoid any reasonable treatment/screen because of it. It was intended to catch asymptomatic cancer. Additional invasive screenings are voluntary and like all treatments they carry risk. I weigh all treatments based on their risks at the time.

For everyday people increased screening of all types has risks, but overall the benefits massively outweigh the risks. If I was a frail 80yo, I might see the risk profile differently.

In my career I've encountered many people who "don't want to know" about medical tests of any kind. I'm not one of those people. Minimally invasive screens early and often please.

No, it's just mindless speculation from someone who clearly hasn't worked a critical service's on call rotation before. Not at all what it's actually like, all these services have automatic alarms that will start blaring and firing pagers, and once scope of impact is determined to be large escalations start happening extremely quickly paging anyone even possibly able to diagnose the issue. There's also crisis rotations staffed with high level ICs and incident managers who will join ASAP and start directing the situation, you don't need to wait for some director or VP.

If the stats were as good as the hyperbole in the article, it would clearly state the only 2 metrics that really matter: predictive value positive (what's the actual probability that you really have cancer if you test positive) and predictive value negative (what's the actual probability that you're cancer free if you test negative). As tptacek points out, these metrics don't just depend on the sensitivity and specificity of the test, but they are highly dependent on the underlying prevalence of the disease, and why broad-based testing for relatively rare diseases often results in horrible PVP and PVN metrics.

Based on your quoted sections, we can infer:

1. About 250 people got a positive result ("nearly one in 100")

2. Of those 250 people, 155 (62%) actually had cancer, 95 did not.

3. About 24,750 people got a negative test result.

4. Assuming a false negative rate of 1% (the quote says "over 99%") it means of those 24,750 people, about 248 actually did have cancer, while about 24,502 did not.

When you write it out like that (and I know I'm making some rounding assumptions on the numbers), it means the test missed the majority of people who had cancer while subjecting over 1/3 of those who tested positive to fear and further expense.

Fortunately, you are very wrong. There is a significant amount of legal precedent that protects decompilation and reverse engineering and it is explicitly protected by copyright laws as fair use. The result is transformative, creative, and completely distinct from any source code the game may have been original compiled with.

People decompiling are not publishing binary blobs. They’re painstakingly writing C code that has never existed before. They own the copyright to that new, original, creative work.

If you own a copy of the game you can use that source code to rebuild a bit-perfect version of the game. Again, fair use. If you don’t own a copy of the game, you can produce binaries that are not bit perfect and are distinct from the original.

The painting analogy doesn’t quite work. To force it, though, decompiling is like writing instructions to reproduce a painting perfectly, but leaving out the tools and pigments. If you own the painting, the instructions will tell you how to figure out the tools and pigments, and you can recreate your personal copy, which was already your fair use right as an owner. If you don’t own the painting, you can use the instructions to create something new and unique. The instructions are not a copy of the painting, it’s a list of steps that is a distinct, creative, transformative work.
Show HN: OVI AI – Cinematic 5-Second Videos from One Image and Prompt
by lu794377 | 2025-10-21 05:24:53+00:00
Hi HN, We’ve been building OVI AI, a text-to-video tool that turns a single image and a short prompt into cinematic, sound-synced clips. It’s designed for creators who want fast, expressive storytelling without cameras or editing.

Key features:

Image to Video with Audio: Upload one image + a prompt — OVI AI generates a short, synchronized video with dialogue and ambient sound.

Prompt-Driven Direction: Control camera motion, lighting, pacing, and emotion using natural-language instructions.

Speech & Sound Tags: Add dialogue, voice-over, and SFX with inline tags; OVI AI handles lip-sync and audio mixing automatically.

Short-Form, Cinematic Feel: Optimized for 5-second, 24-FPS clips — perfect for TikTok, Reels, Shorts, or quick branded teasers.

Identity & Style Consistency: Keeps facial details, mood, and style consistent across renders.

Fast Iteration Pipeline: Save prompts, tweak tone or tempo, and re-generate variants instantly.

Why we built this: OVI AI is about speed and creativity. We wanted to make cinematic video generation feel as quick as writing a caption — helping creators, marketers, and studios produce polished micro-stories in seconds.

We’d love your feedback on:

How you’d use 5-second AI videos in your workflow.

What tools or APIs could make OVI AI easier to integrate.

Something pikapods looked neat at first then soon I realised the costs add up and add up a lot. One day I was calculating it at pikapods at I realised I had crossed 27 USD/m and I wasn't even finished. Like those streaming services - everything on a new streaming service i.e a new pod and they cost separately. I wish there was a service which would take away the pain of installation and maintenance away from me but let me host a lot of absolutely single user (i.e. only I'd access that of course) and as light weight as it can get and as low in usage at it gets on one single "pod" or "instance" or "box" and charge for that. Also, it's not a pikapods or pikapods' problem, it's a general problem I believe.

> This is completely irrelevant to anything. It's none of the business of the tenant how much the landlord is profiting

It certainly feels relevant when they start making excuses about why they have to charge you for things they cannot charge you for, claiming how expensive things are now. Operating costs have gone up for everyone, that doesn’t mean you get make things up to pass down the cost. But I do understand your point.

> Where I'm from the corporate landlords don't even charge deposits when you have good credit and income.

True, that has been my experience as well and I wasn’t explicit about that. The last couple of places we rented were from corporate ones and have had 0 issues compared to the mom and pop ones.

> splitting a line into words is a whole project on its own

Is it[1]? My version below accumulates alphabetical characters until it encounters a non-alphabetical one, then increments the count for the accumulated word and resets the accumulator.

(let (c accumulator (counts (make-hash-table :test #'equal))) (handler-case (loop (setq c (read-char)) (if (find c "ABCDEFGHIJKLMNOPQRSTUVWXYZ" :test #'char-equal) (push (char-downcase c) accumulator) (when accumulator (incf (gethash (coerce (reverse accumulator) 'string) counts 0)) (setq accumulator nil)))) (end-of-file () (when accumulator (incf (gethash (coerce (reverse accumulator) 'string) counts 0)) (setq accumulator nil)) (maphash #'(lambda (word count) (push (list count word) accumulator)) counts) (format t "~{~&~{~a ~a~}~%~}" (reverse (last (sort accumulator #'< :key #'car) (let ((n (second sb-ext:*posix-argv*))) (if n (parse-integer n) 100))))))))

It’s not exactly pretty or idiomatic, but its 19 lines appear to get the job done.

I have a bunch of these 8x8 panels on their way from AliExpress right now for an art project that a part will look remarkably like the video. V1 will probably be a 32x32 just like it.

I still haven't decided if I want to have a partition grid between the panel and the diffuser to make square edge pixels. It's definitely going to have a rp2350 inside. PIO is the best thing ever.

Case I read in the JAMA which I get because I signed up during covid.

Late 20's Hispanic lady shows up in the ER with what they think is probably food poisoning. But they do a CT. Which shows changes in her liver which probably is a fatty liver. But they do a biopsy just in case. Biopsy results in a bleed which requires a transfusion and 4 days in the hospital. Biopsy result, fatty liver.
