skysight-inc/HackerNews huggingface dataset:
Sure, the system takes a raw camera feed and spits out an entry into a sql db which will then, depending on customer requirements, be provided in a format they want.

In between these steps, (all based in python) opencv takes the video, splits it, sticks some of the frames on a kafka cluster.

Another node picks up approx 2 fps, hands it to a object detection algo based on tensorflow which then puts the results on another kafka topic.

A heavily customised tracking algo pulls all of the frames available and the tensorflow results for initialisation and reverification. Once a vehicle is tracked through the field of view the vehicle is counted.

For the privacy issues, as this is only tracking for a short amount of time, not tracking between intersections and not tracking persistent uuids or numberplates, there shouldn't be too much trouble. But it will depend on the local law requirements.
As this is a statistical problem, tracking the actual path of a car between point a and b isn't completely necessary if you can get a sufficient amount of coverage over a city. (You probably already understand this.)

As for opening the datasets up, I plan to do this with the poc. I've been using the Biloxi Mississippi camera live stream from youtube for all of my testing so far. My poc will be a website with this live stream having an overlayed view and the ability to download the stats for the day/month/year etc.
As for other cities, I'm sure a FOIA will be able to get you the data. But I will be pushing to publish it openly as they will have to pay for it either way.

As you can probably tell, I'm trying to turn this into a business and the costs of actually collecting and processing the data isn't something that is reasonable for single person to bear. After talking to the traffic dept for my country, the largest city of 1.5m has about 3000 cameras. But I am aiming for a system that's cheap enough to enable 24/7 monitoring as that's when this all gets pretty exciting.

In addition to the excellent answer by the author below, I'd like to say that Julia can get within spitting distance (or even sometimes exceed) C++ speeds (and even BLAS). So if a comparable amount of work went into optimizing specific paths through generic code (or even the generic code itself), it could be as fast. Also, one can write CUDA kernels in pure Julia.

> Apple switches architecture when it suits them

The question isn't whether it suits them. The question is: "Why did they choose to take on the level of risk in this portion of their business and what is the core benefit they expect?"

If the the main reason was cost savings, this would be a horrible way to go about it.

There's a better answer: Intel can't deliver the parts they need at the performance and efficiency levels Apple needs to build the products the way they want to build them. This is not a secret. There is a ton of reporting and discussion around this spanning a decade about Intel's pitfalls, disappointments, and delays. Apple might also want much closer alignment between iOS and MacOS. Their chip team has demonstrated an ability to bring chipsets in-house, delivering performance orders of magnitude better than smartphone competition on almost every metric, and doing it consistently on Apple's timelines. It only seems natural to drive a similar advantage on the Mac side while having even tighter integration with their overall Apple ecosystem.

Anyone know what happened to Intel over the past 5+ years? They used to be unstoppable, relentless, the best. Have they had trouble recruiting the best engineers? How have TSMC and Apple been been able to pull ahead in terms of being at the lead of CPU development?

I thought maybe Intel was losing ground to TSMC for cultural reasons – being the best while being based in the US is getting harder and harder. But I'm not sure.

> Like how would AP courses benefit a rural schoolkid other than maybe getting access to work in a city? Could we think there is any education for him to be a good farmer?

I think this perhaps misunderstands the typical life paths of rural students.

20% of the US population lives in rural counties, but only 2% of the population works in agriculture. And even that over-estimates the number of school children who will grow up to be farmers because a huge amount of the unskilled farm labor in the US is done by first generation migrants.

So the average rural schoolkid in the USA isn't going to work on a farm (and the ones that do will often be skilled workers or owners and will therefore go off and get agricultural degrees.)

The government runs a lot of jobs programs for rural areas. Things like state/federal prisons and military bases are intentionally placed in rural areas to provide employment opportunities. And of course national forests/parks tend to be in rural areas and provide a small but steady stream of jobs. We also explicitly subsidize hospitals and schools in those areas; the local tax/consumer base probably couldn't support those services on their own. So the government sector is the lifeblood of many small towns these days, at least as far as employment goes.

The problem is, it seems to be not so much about space efficiency, but about streamlined appearance (e.g., there's now less horizontal space and fewer controls are shown at once), which translates to low semantic contrast, wich again translates to lower work efficiency. And it's the latter, which causes most of the criticism, as not all users want to trade personal time and usability for looks (or prettier printouts of the UI).

Yeah, this was how I was trained to do it. A ballpark estimate on the spot at best is around 30% accuracy. I normally wouldn't give an estimate unless I can break it down the work into less than 4 hour chunks. Proper estimates also contribute to work done as it involves the design, but it's normal to spend a few hours doing estimation.

Trained managers are familiar with the cone of uncertainty, though.

But what I really mean is stuff on the level of powering a toaster with a car battery. It's certainly possible, but nobody has documented on what they did, and there's a very high number of uncertainties as neither were designed to perform this way.

They already have their own, custom GPU on their A-Series SoCs, so them hiring people working on GPUs is hardly surprising?

I think in the next 5 years this will be in Apple's favor. The issue is more of a 10 years down the road question. Intel always seems to lag for a while and then starts leap frogging. I don't know if that cycle continues, but it might...which is a risk to Apple.
> Topping my list is support for SVG assets. NOPE. WTF?

PDF assets have been supported on all Apple platforms for many years.

The announcements today represent years of work by thousands of engineers and designers. It’s impossible to cover everything in a 2 hour keynote, let alone one geared towards the media/general public.

Wild prediction here, but I think this has largely to do with their VR/AR business. Sure, having a platform to manage more spatial data is cool, but I don't think this adds that much value to their current data.

In comparison, it could be bleeding edge for AR. There are few companies with a notable footprint in the street imagery business. Google is obviously number one, HERE has their own fleet and I think maybe TomTom and a few others actively capture this data.

What none of those companies have, however, is a flourishing VR/AR play. Zuckerberg is clearly bullish on VR/AR and Oculus is largely leading the consumer market.

This is where my prediction gets wild, Facebook intends to replicate real world environments in virtual reality. This is what OpenSfM could potentially do with enough hands on it.

I spent a considerable amount of time trying to do this myself. Photogrammetry is still in its infancy, but it works. I replicated my office in virtual reality using a phone app and Unity. I wanted to do the same with a single street, and that's how I first came across Mapillary. The technical challenge was too much for me, but I know it's possible based on literature.

Imagine doing this at scale with a network of vehicles and much improved software. You could, hypothetically, replicate the roads of New York City in a 3D environment. Imagine playing a video game in a real world environment, or simply being able to walk the streets of a place you've never been before. These could be transcendent experiences.

I think gains in I/O will be more noticeable than gains in their CPUs. SSDs are being choked and held back by PCIe 3.0 interfaces at this point. I'm not sure that PCIe 4.0 is any better on latency. It would be interesting if Apple took a big leap forward with a low latency interface like OpenCAPI, or maybe some iteration of RapidIO. Something like Optane over OpenCAPI would be a huge leap in speed. Optane is wasted right now with PCIe.

The PS5 apparently has incredible disk I/O, possible due to RAD's compression technology. A super fast compression codec could make a difference too.

Unfortunately for high priced premium products, the increase in quality of basic products forces premium products to be better or fail.

Related to your example - $1 burgers are increasingly better, than you would expect. The difference between McDonald's midrange line and, say, a burger at a restaurant for $18 is negligible in flavor. I can no longer justify going to a restaurant and pay $18+tip for a burger.

What I find a little bit surprising with this is that the behavior of a library can be changed outside of its view. E.g. if the library requires to always run in an evented mode (because it needs to spawn many small tasks), then the application developer settings things into threaded mode might prevent the library from working properly.

Similar questions might arise around cancellation and timeouts, which are different to perform in an async/evented environment than a synchronous one.

In most other worlds the problem is "solved" by declaring a subsystem of the application as async. And only that subsystem is running one or more eventloops. That obviously introduces a different set of issues, but it isolates parts of a program against others.

I'm really curious on how Zigs approach will work out in any bigger applications where libraries from various parties would get used.
Wait ... is lynching a federal crime or not?

If a lynching occurred tomorrow - an overt old-fashioned lynching, complete photographic postcards for sale, could it prosecuted in federal court?

I’m confused because places like the New York Times talking about legislation that would make lynching a federal crime. But a few years ago they were talking about how Doug Jones prosecutes historical lynchings as a federal prosecutor.

So apparently Doug Jones was elected to the Senate for prosecuting lynchings, which aren’t actually against federal law.

Something is wrong with this picture.

I suspect that lynchings have been illegal for a very long time, but under more general Civil Rights legislation.

c is the speed energy travels at and less than c is the speed matter travels at in the universe. You’re right that ultimately matter is energy, but you typically have to introduce it to it’s antiparticle to turn it into energy.

(I’m less clear on how you go from energy to mass. I think you can knock a photon into an electron with enough force to escape its nucleus but you’re not going to get new matter out of it. I wonder whether further knowledge of the Higgs Boson would give us some ideas in this area.)

So photons can’t transmit forces dependent upon mass - but they can transmit momentum. I remember being told this is what keeps a stars gravity from collapsing the matter into a singularity or otherwise blowing apart.

I think you’re probably right that speeding matter up to significant fractions of c would increase its effect on your opposite velocity, but it’s probably hard to benefit from as an engineered system. Like having a particle accelerator the size of our orbit around the sun to make meaningful thrust-hard.
Previously I would have thought they could be separate but as of Catalina it’s entirely possible that all their stock apps are part of their protected volume (and therefore not updated in any normal way). The Applications “folder” is a virtual view merging multiple directories on disk.

There's a cultural issue at the root of it. There are places with more racism, more inequality, and more absolute poverty with significantly less violence, and crime has gotten worse while we've made progress on civil rights issues and racism over the past 50 or 100 years. Popular culture within American ghettos glamorizes violence and crime. This is probably a very popular opinion in reality but vocalizing it is, ofcourse, social suicide. Having said that, I support the current riots as police brutality and institutionalized racism are severe problems that needs to be fixed.
