Show HN: AI video editing for action sports
Hey HN,

I made an iOS app that can automatically create clips for BMX and MTB from long videos.

Why: Manually editing got annoying when I would attempt a trick dozens of times. Stopping to edit would break my flow.
Checking your form frame by frame in a 15 minute video is basically impossible on iOS.

Who's it for: BMX and Mountain bikers that record riding videos on their phone, especially when they're attempting new tricks or riding a feature with friends.

How I built it: Written natively in Swift.
Trained a custom YOLOv8n detection model on 16,000 images self-annotated images.
The detection model runs locally on an iPhone 13 Pro max with a 3.03mS prediction performance.

What's next: A session feature where multiple riders can connect to a 'Session' where one phone is set up to record a feature and everyone can see their clips without stopping and starting the recording.

Thanks for listening!

It has that potential for sure, but I hope the people researching and developing these tools aren't that optimistic. We need to be skeptical until treatments are proven, going in optimistic for a field-changing breakthrough is a great way to misread the data or fail to design proper studies.

The credentials for service accounts are generally available to a system admin but I think in most cases it would be a strange request to ask for them, so not a strong vector for social engineering.

A service account is used to give limited permissions on one system to another system. Normally only that system would need access to them, not any human.

Their main benefit is that, since no person is trying to do their day job here, the account can be locked down to precisely the permissions it needs. The reality is that service accounts are usually given extremely permissive access initially and then forgotten about. This makes them juicy targets for attackers.
They typically do, by picking the product they wish to use.
Pretty common in finance across the board to use consistent units and to not use decimals. So in this case the following sentences mention $10 million, you would not want to say $0.10 billion. It depends on whats being presented of course but in large numbers like these, decimals make it harder to read.
Uno Maintainer here - Thanks for trying out Uno! At this time, the default render mode is provide a uniform look across platforms, and it's possible to alter the theme using Material, Fluent or Cupertino, or to design your own theme using control template styling, or even use native controls directly where applicable.

On Linux, we've just released our support for X11, removing the need for GTK. As we're drawing the whole app surface, we're always interested in adjust the UX of our controls on individual platforms. If you have examples, let us know.

Finally, for WebAssembly, our current rendering backend is using the HTML DOM, which means that accessibility and other native behaviors are functional. Same here, if anything accessibility related is missing, we're all ears!

I've said this before on HN, but neural networks are not a tabula rasa. Their structure is created by people. With better domain understanding we can make better structures for AI models. It's not an either-or situation.
People confuse a economic recession with what is happening because of how words sometimes change their meaning away from their technical to a more colloquial interpretation. The economy as a whole is doing well, but people aren't because of inflation. Recession is just the word they've learnt to interpret as "I'm feeling poorer".

And the stripper index is down because their market is oversaturated aka "onlyfans overload".

Searching for BFR will uncover resources for this style of exercise as it's common in physiotherapy and bodybuilding.

Just a note though: avoid the bodybuilding "bro science", there is an established method to calibrating BFR that doesn't merely involve putting wraps around the arm or leg and hoping for the best. The main harm is cutting off too much blood flow by using a cuff that is either on for too long or can gather in a way that progressively cuts off circulation during the movement.

The core advantage of BFR is one can use a lighter weight to achieve similar results, which can improve the surrounding conditions of your limbs (joints/tendons), it is no less tiring or strenuous(on the muscle) than regular exercise.
With k = 1/x, the inverse weight interpolation is equivalent to bilinear. Perhaps it's better to show the result for k = 1/x^2.

Neat aside, k = 1/x^∞ seems to be equivalent to nearest neighbor. (please excuse the abuse of notation)

It is very complicated to get this right from development standpoint. In true E2E, client must be "fat", kitchen sink and everything. Pretty sure Dropbox isn't like that right now. E2E is not a "feature", it is like a different paradigm of problem solving.
I think your explanation is missing a competitive element that drives the $500 price. Two similar examples:

1) Maximum City is a book about various people in Mumbai around ~2000. One of them is a sort of stripper (she dances and sometimes dates in a transactional way; I don't remember how explicit it all is). Her analysis is that her clients are partially paying for her but more so for "winning" her over the other clients. The point isn't that one of them takes her shopping and gets to watch her choose handbags; the point is that nobody else gets to go.

2) I read a long article about economic strategies behind webcam shows (by a performer, maybe by Aella?) and the author made two points that I remember: one, it's good to have a stupidly high priced item that a whale can roll in and buy. Two, she had success having a high priced item that "saved" her, e.g., if you pay $X I won't have to eat this gross thing I made. Neither one of these is really about the thing, it's about the feeling of out-competing the other guys there.

So while you're $500 example makes sense if somebody is just looking for the dance (or whatever) itself, it doesn't make sense if that person actually wants to "win" over the other patrons (and doesn't view the poorer patrons in the poorer country as real competitors).
Yeah, the shameless self promotion without providing any value yourself.

I put an image of villa isnard, cascina, Pisa, and it was recognized as being from France. It is a villa with French architecture and olive trees. I then tried to upload an image still from Pisa with a building in venetian Gothic style and it was recognized being in Venice. It can be deceived quite easily imho, it looks like it just search for the corresponding architecture (maybe?) and details surrounding it but it doesn't search online. Villa isnard is quite famous (at least, you have results online) and a Google lens search would have found it

They're smart enough to know how create filters that don't miss people with competitors experience on their CVs. In fact, they actively seek those people out on LinkedIn and anywhere else they can find them.

Hey Lightherder, good seeing you share more of your work on HN. I submitted one of your videos a few days ago as i thought it might go down well here. You really are a craftsman. And the effort you go to and the results you get are extraordinary.

Nobody asks you for your age when you are doing IQ test before giving you your result.

Originally IQ was defined as "mental age" divided by actual age and it was for testing development of children. The actual age was capped at 16. So it was expected for any person 16 and over to have the same result in the test to have the same IQ.
It's really just down to the size of the site/service and Dunbar's Number. Whenever a site or service gets big enough that you can't really know everyone who's active there, then it tends to spiral towards toxicity. Hence why big forums used to be a lot crazier/dramatic than smaller ones, why social media platforms tend towards becoming a cesspit over time, and why the means of which a platform is run matters less than people think civility wise.

This comment beautifully assembles everything I hate about institutionalised "science".

> as if they stand on the same esteemed ground as the countless individuals throughout history who have propelled scientific progress

There could absolutely not exist a more anti-scientific sentiment than this. This sentiment is what erodes the core of development. Esteemed my b*t.

As a tenured professor you ar entitled to absolutely nothing. The fact that you decides masochism on yourself does not allow you to have any masochistic behaviour towards students and staff.

Science is about accepting and realising the ideas that best possible describe the real world. If you can get direction out of history to do this well, be my guest. But do not set history og science up as a dogma to access an exclusive group.

What this comment is describing the the "religion of scientific institutions" and has nothing to do with science.
Assuming this is more of a proof of concept/prototype, that's not bad. It didn't get it[1] right, but at it's core, the guess is not terrible, shift it 560km[2] south-east and you'd be bang on. I'll admit, I did set the bar a bit high.

Show HN: Instaclass – Make a Masterclass on Literally Anything
Hi all! We're Flynn, Moe, Bryn, and Porter, and we just launched Instaclass. Instaclass lets you make a masterclass on literally anything, using the best content that's already on the internet.

This is the culmination of months of work in the AI content consumption space that we started last year while working in gaming. A huge part of our work was dedicated to creating content with generative AI, but the biggest lesson we learned was how much content is already out there! Practically everything you could ever need or want, in any niche, has already been created by someone.

The trouble is finding these gems! When starting out with a new hobby, or exploring a new interest, we often don’t even know where to begin. What do you Google? Where do you look for content? How do you know what’s good or bad?

We originally set out to answer these questions with generative AI producing the content for you. However, this wasn’t great and it got pretty tiring to have AI summarising everything for you again and again.

With Instaclass we’ve flipped the script. AI does the searching for you, bringing everything you could possibly need to know on a topic into one place for you - in under a minute.

No more searching for hours, scrolling endlessly to try and figure out your next search as you wiggle your way deeper on a topic.

The team and I use Instaclass daily to learn about brewing better coffee, the Fallout universe and lore, the French Revolution, and cooking tips from Gordon Ramsay. We’ve joked that this would have been really helpful in the early days of each of our previous pivots - if you know us then you’d know that the one on how to build video games would have been worth its weight in gold…

Users of ours have done everything from learning how to give a sales pitch for an interview, to how to be nice to your boyfriend. It’s good for any and all deep searches, and takes the pain out of finding what you need.

Try it out and let me know what you think! We are limiting free credits at the moment so if you run out, join the waitlist and we’ll email you when more become available. Looking forward to seeing what you all make!

There is no such thing as an "SSL certificate" or "TLS certificate". There are certificates, which are used in various protocols including SSL and TLS. You can use the same certificate for both. The name "SSL certificate" is just a shorthand indicating the intended purpose of the certificate, nothing more. As such there really is no point in being pedantic over SSL vs TLS.

That's how I read it. I'm interested in consciousness, but neither in terms of "self-awareness" or of "awakeness". Awakeness just means you aren't asleep. The term "self-awareness" implies awareness, which might be what's meant by consciousness, and it assumes there's a Self, which is a metaphysical concept, not susceptible to scientific invetigation.

Personally I supect it might be due to differing expectations as to what social media conversations are. I think those who weren't super active on forums and other old school chat systems think of them as closer to a chat between friends in a bar than between randoms on the street, and struggle to handle the idea that anyone in the world can reply at any point.

But that's kinda the thing. As you said, the whole 'messages with reply text box' design is set up to encourage responses from whoever wants to respond, and social media services are closer to a soapbox in Speaker's Corner or maybe Times Square than a chat between friends at home or in a restaurant.

That wouldn't be weird at all. The Republican party has many different factions. It would be weird to imagine the neoconservatives advocating those positions but the neoconservatives do not advocate those positions. And the neoconservatives are leaving the Republican party. It wouldn't be weird to imagine the paleoconservatives advocating those positions - sounds like typical Pat Buchanan policy positions.
To a certain extent, you are correct. However, companies like Jane Street need to filter and doing so based on colleges is the most efficient when other factors are all equal. Top tier colleges strive to base their admittance on performance and strive to be racially and culturally diverse. This gives Jane Street the ability to say they filter on the same criteria.

I'm all ears if you have a better system that is more efficient. I'd also add that I went to a State college and my resume would have been tossed if I applied as a starting engineer too.
