> Most of the video I see on YouTube these days is in VP9 or AV1. Occasionally some video is still H.264.

can't shake the feeling that most videos at 720p took a hard hit to quality within the last years (or my eyes are getting better)

any deep dives on the topic appreciated
Hadn’t expected to see this here! I helped put this standard together while working at Opal Kelly.

I think we had some nifty ideas in there (using an analog voltage for peripheral addressing was one of my favorite). It has slowly seen more adoption as time passes. Would always love to see more adoption!
I'm not sure knowledge of technologies is ever more than a temporary distinguishing factor. I think engineers are distinguished more substantially by a depth of understand of the fundamentals. By definition, fundamentals do not change as much and are less subject to styles and fashions.

Perhaps you're asking "where will the low hanging fruit be in 5 years time"? I think that's always difficult to answer because software tech can go from obscurity to ubiquity and back again in a short cycle. I think it is roughly like picking winners on the stock market.
Could your reasoning be any more condescending to people? What because a computer program spit it out, you think the poor uneducated masses are going to accept it at face value? Really? You ask about the context… great question! Well, the answer is simple, the context is all written language. These LLM don’t spit out text from nothing, instead, their context is all of humanity’s written work.

If you’re not happy with the reasoning that comes out of that training, then point your finger and humanity, not the tool that’s just summarizing it. Don’t shoot the messenger.
> The obvious thing people seem to be missing is that the process of creating something is fun to creative people, that's why we do what we do. It isn't a chore to enjoy yourself.

Yeah, the AI sales pitch usually doesn't highlight that they really want to take the fun out of a lot of stuff and replace it with drudgery.

Automated development with AI! Spend all your time doing code reviews instead! Fun?
There are 3 problems with this approach that make Vercel / Netlify much better options:

1. People delude themselves into thinking that they have the magic unicorn project that will blow up to a million users in 1 day.

2. People are out of touch with how fast computers are these days, and don't realize that a single server can handle a huge amount of traffic.

3. People lack the skills to build out their own infra in a time efficient way. With all the tools and free knowledge we have today, it is trivial to set up a small network of small servers around the world for a small business. People lack the skills to do this, pay too much for cloud compute, then justify it to themselves that "it's cheaper than engineer time" - when in reality, if they were better engineers, it wouldn't take a lot of engineer time.
I don't fully agree with your statement. We had used Scala around the time the devs were playing around with dotty. I loved many features of the language (compile times were painful, but the language itself was fun). But we had to stay back because a specific db dependency did not resolve well with later versions of Scala (2.13 it broke).

Similar thing recently, there was an obscure Scala version mismatch error when trying to use it with spark. (Not that significant of a problem).

It is definitely a headache trying to cope with the conditions till we get better especially with smaller teams who can't afford to fork and maintain something.

If the could decode it, the Golden Record [1] onboard Voyager will point them directly at us, if anyone ever finds it. I doubt that's going to happen, simply because of how small the spacecraft is and how insanely large the universe is.

I'm convinced that this guy sees Musk and his outlandish statements and thinks that must be the secret to success and so tries the same thing, but going even further. What he seems to fail to realize, which is strange because what he does deliver in value shows that he gets it in other realms of business, is that you have to actually deliver something. It doesn't have to be your exact claims, but something approximating them.

Musk says he wants to colonize mars. He's currently testing his 2nd generation rocket that's capable of carrying 100 people. His car is orbiting the sun. Bezos says he wants to colonize space with a trillion people, so far he hasn't gotten so much as a brick into low earth orbit, much less even articulated how to create a trillion people.

But he built one of the worlds foremost and innovative logistics networks. I don't understand, he's not disconnected from reality, the existence of amazon proves that. So why the bullshit on space?
> who is being censored…
The author of the program obviously.

If I write a bash script that echos “kill all the Jews”, and you choose to censor it, just who do you think is being censored? The intel professor? No! The author of the bash script obviously!
> And throughout all that process, Microsoft thought this is a great and safe feature for the users.

I’m fairly sure plenty of people in Microsoft would have realised that this was a terrible feature. But sometimes, it is easier to just let emperors go shopping for new clothes.
I see Americans will ...

You have no bleeding idea what I am. But you are welcome to be disgusted by whatever you like.
I hate to break it to you, but yeah. There are, sadly, many countries in the world that rely on petty and punitive action on harmless things online in order to frighten would-be "troublemakers".

It's not just Russia, either. The UK does this almost three times as often.
> If you are replicating changes from only a few tables, ensure that you create a PUBLICATION that includes just those tables. Postgres efficiently persists changes for only those tables in the replication slot. This helps reduce the size of the replication slot and improves logical decoding performance.

where is this coming from?
I do have a PS5 but I prefer purchasing games on Steam if I have the option since I know those games are practically guaranteed to be forward compatible long term. I’d love to ditch Windows though. I hope Valve continues to make progress with Linux gaming with the Steam Deck.
An OS will never protect every wallet; the user can move to an OS and wallet combination that provides sufficient protection for them.
Did you check the execution plans before and after? Probably caused a different plan that happened to be faster by luck.
Hey team, nice work. Can you help me understand this better. How does the process work in terms of the human agent evaluations? Is it real time so that the right (maybe a better word is best) answers go to users as they are needed, or is it done asynchronously/batch style so that the humans are training models to be better? Once the best answers are selected, is it fed back into an LLM / AI agent model? Thanks
"Cameras all use H.265", curious , what cameras are you referring to?

While some cameras do support it, it's much more common to use ProRes, DNxHD/DNxHR or h264 in all-intra mode (as e.g. in XAVC-I and XAVC-S-I).

h265, or long-GOP codecs in general, are only really used for long talking head shots or lectures.
Marketing.

Which is generally the main thing in AI-land, really.
Hi, mind sharing the links of your talks or slides? Thanks!
Seems unreasonable to regroup by yourself, no?
it's been downhill ever since excel 2003 imo

excel used to almost be a joy to use; now it's sluggish, inconsistent, and buggy

i mostly use excel 2010 now as it's a little less obnoxious than the newest builds...

i look forward to not having to use this steaming pile though I suspect I've got another 20+ years of it :(
Taran (ex LTT member) has an excellent video on it as he unfortunately experiences negative side effects: https://www.youtube.com/watch?v=xQDAXSbwhR0

Edit: I misremembered, he got PRK, but he does talk about consequences of both methods.
Because they’re trained to.

I hate the introduction to the response. That’s not even trying to be human, i don’t know something more like a deranged patronizing butler.
The problem though is that those marketing this stuff want it to be taken seriously. They have to sell the "I" in AI. They can't tell you "this is a toy and is not intended for real world use for any consequential purpose", because then they wouldn't have a business.

It should be obvious, youre right. But people are being bullshitted and then blamed for believing the bullshit.
Yeah fair enough. I was talking mostly from the perspective of young European urbanites, many of which now are turning the lack of a driver's license into a status/social symbol and scorn at you if you even talk about car ownership.

Also car tuning and tinkering is expensive and youngsters here don't habe the money for that, they'd rather travel the world or put it in bitcoins than spend it on restoring old Miatas or buying a Tesla.

Motorcycle enthusiasts though don't seem to be lacking.
The most charitable positive spin on this is that his connections will help stop government from going fact-less banhammer on AI in general. But jesus I would assume most peoples brains can go real negative on this one.
> I have a hard time thinking that kids are just naturally "not clever" - I think any kid can be extremely clever if given the chance to explore and play and grow.

What makes you think this? Plenty of adults are naturally not clever. Half of all adults are below average. Why would it be any different for kids?
But when it is made by Nvidia, that means it will not work on AMD GPUs. I do not consider this kind of thing a solution, but rather a vendor lock in.
Yep, 02016 = 1038
I disagree. My desktop has 12 cores and 16 GB RAM, and I build software on all 12 cores regularly without any problems.

The only times I ran out of RAM because of builds where actually single thread ones: accidentally linking clang with debug symbols and a single threaded verilator elaboration of the XiangShan core.

I don't know whats going on with your setup, but I regularly have two firefox windows with a shit ton of tabs and discord open and struggle to get over 3-4 GB RAM usage.

I also just build ffmpeg and 7zip on the same 8 core risc-v system, but with 4GB RAM and didn't have any problems. It was running in tty though.
That’s totally true, though people routinely make bad decisions that get them killed while on a couple glasses of wine. In 2023, in the U.S., where I live, more than 100,000 people died of alcohol related causes, while a mere 10 people died from skydiving, out of almost 3.5 million skydives. Romania (where you live?) seems to have pretty high per-capita binge drinking. Maybe drinking actually is closer to Russian Roulette and skydiving is further than it seems at first…

Parent comment is also totally true: there are lots and lots of enjoyable and risky activities. Driving your car is very dangerous and results in immediate and gruesome death for hundreds of thousands of people every year. People do rock climbing, river rafting, heroine, fentanyl, motorcycle racing, boxing, scuba diving, football…

Maybe you also take unnecessary and potentially terminal risks, and don’t even get the adrenaline benefit.

That wasn't the experience in the article:

> A four year old with a 3rd grade reading ability learns about a WHOLE lot more -- it opened up politics for her. She would read our junk mail, and learn who our council member was, who our representative is, the mayor, current events, history, etc. I know it's stupid of me to say, but I underestimated the effect that reading early would have on her breadth of learning.
You can go carting at your local outdoor track.
> Hardware support has also been ubiquitous for a while now.

With how limited browser support for h265 is, I always have to encode an h264 version anyway.

At that point I just encode a 720p h264, a 1080p h264, and a 4K HDR AV1 encode of all media I store.
Following up on my own question. I re-read the github, so I can clarify my question better. So the AI agent responses are saved to a database where the human sme can classify responses as good/bad right? Do you intend for the result of this analysis to retrain the AI agent, or is it purely to get a baseline on the as-is AI agent quality?
A very cynical take. I expect we’ll pass it in 20-30 years.
I think the exponential map is still the most robust way to think about rotations, since it gives you tools to deal with the Lie group of SO(3) in the most straightforward way (switching between coordinates, dealing with differentiation and tangent spaces, etc.)

Even when going through all the formulations with geometric algebra, you still land on using rotors (isomorphic to quaternions) and motors (isomorphic to dual quaternions) to represent SO(3) / SE(3) spaces - but I think for that purpose 3x3 rotation matrices / 4x4 transformation matrices with exponential maps are still much more useful. (Quaternions do have an advantage that it stores up less space and also faster to multiply with each other - but when you want to transform points with it then matrices are still faster. In overall in terms of efficiency it really depends on the situation.)
There are plenty of nontrivial transformations that compilers still have yet to do if you are looking for "art". This just automates a class of optimization so it can be done reliably and generally.
The linked article does not support what you say in any way. If anything, it argues that invasion of privacy can actually be used against somebody by getting things out of context. It is definitely not what the link talks about, spending 1/3 of the text writing about how wrongfully invasion of privacy was used during Clinton's impeachment. Maybe you meant to share something else?
That sounds like a great deal, and I did spend more than 2k jumping. Keep the rubber side down!

Plants eat radiation too, just with a bigger wavelength. So it's kinda photosynthesis on a roentgen-wavelength
I think there have been advancements in RL that deserve to be on this list. AlphaFold at the very least; I hope you had the pleasure of reading the reactions of researchers who work on protein structure determination and how stunned they were that their field of research had been in large part solved.

Here's a few more that come to mind:

- Work decoding brain signals that allowed paralyzed people to communicate via a computer (this all happened pre Neuralink)

- I think self-driving cars fit your criteria, even if the jury is still out as to whether this has/will soon be 'solved.'

- In gaming, Unreal Engine's Nanite is very impressive and a real technological innovation

- There are efforts to get LLMs to learn via RL and not just from training on huge text corpuses. Actually mathematics is a prime example where you might dream of getting superhuman performance this way. People are at least trying to do this.

Just because there's a lot of BS which tends to drown everything else out, doesn't mean there isn't real progress too.
Our son showed an interest in letters before he was 2. He would point at an S and say Ssssss.

So at age two and some months, I made a set of flash cards for body parts. So we would play "the body parts game", where I show him a card and ask him to try to say the word and to point to the body part. He thoroughly enjoyed this game. We did it in both languages (we are raising him bilingually.)

I tried to use a bit of creative fontology (is that a word?) to de-emphasize silent letters, like thum(b) and (k)nee, and to mark letter combinations like ch and sh. When he asked about the silent letters, I could only say that (for English) spelling is different (and kind of stupid).

Obviously spoken language is the baseline in all this.
this -- fascinating -- document about porting the code for the Pioneer/Voyager Cosmic Ray Subsystem[0] does not specifically mention which _workstations_ were used, but the doc is hand-dated to be 4/15/93.

so for servers maybe SPARCservers and SPARCcenters and if they had good budget Sparc 10s for workstations? probably had a ton of IPXs and IPCs around the place.

this doc from february 1995[1] "a study of workstation computational performance for real-time flight simulation" used a variety of SPARCs as well as other workstations from HP, SGI, IBM etc. the Sun workstation benchmarks are not good!

Again, the Imans would love to moderate your internet.

They don't want to hang you for it.

They just want you to never hear anything positive about homosexuality and the people they are hanging.

Understanding this is very difficult for people who support their governments form of censorship, like everyone working at googleface.
It will come from the rest of the world. A 10 mio people city in Africa needs just as many 5G base stations as a 10 mio people city in the US.
Voyager 1 has had an almost 50 year head start, and it was launched with a series of gravitational assists that are only possible every few hundred years. There is 0 chance anything will catch up to it in the next 50 years, and probably for several hundred more years after that, if ever.
Oh, thanks. I see now.

I find it difficult to take the technology review seriously with the off topic remarks and prefaces about Musk and Tesla at the beginning of the post.
A bit offtopic. Nitpick regarding definition of “root cause”.

Let’s say there are two conditions X and Y.
Neither sole-X nor lonesome-Y, cause the disaster, but when X+Y happen together, they produce a very negative outcome.

It would seem that both are equally “root” of the cause. But human brain desires to declare one as primary.

In situation where disaster was “human died”, with conditions X=“bullet was shot at the human”, Y=“humans are squishy”, we naturally would lean towards X being the root cause, while Y would be treated as ”that’s just the way it is”.

On the other hand we could construct ”human died” situation with reverse root cause assignment, ie. X=“bullet was shot at human” is taken as a constant, while root cause is Y=“ humans are squishy” (employing some grotesque reader can construct a better one, but something like “The journalist should have followed the process and used a bulletproof vest. It is a war zone after all” seem to work)

“Root case” usually is the smallest and most easily changable part of situation that can prevent disaster.

Though the “ease of change” is not fixed. (“People must follow process” vs “invest milions to change process”)

I just wanted to ramble a bit on the concept of “root cause”. To highlight that on precision-of-terminology-spectrum that spans between mathemathics and astrology, “root cause” falls somewhere in the middle. (probably bit to the right of engineering)
Ladies and gentlemen, this is what a sore loser looks like. No arguments left, only smears. Desperate because you are used to that your bullying tactic works, that people back off and gets sidetracked, but here it didn't, which I already explained to you that you get nowhere with that here.

Swedes rejected your ideas, first in the general election of 1976, were Social democrats got ousted and lost an election for the first time in 40 years, and the second time in of the largest demonstrations ever recorded in Swedish history, the 4th of October demonstration of 1983, against fund socialism.

And if you are old enough you saw your own movement die with the fall of the Berlin wall on the ninth of November 1989. I remember, I saw it on Television.
AI don't need to be competent to cause harm, just like humans. Just ask law enforcement arresting people because their face recognition AI told them to.

Not that I trust governments trying to oversee them either...
Thankfully I didn’t say “what a star is” was the fuzzy thing! :)
Most of this AI stuff is sorely lacking a "feedback loop" If you aren't collecting data on angry/ unhelped customers... you are just flushing your business down the drain

Also maybe it is just me... but I would never call customer service unless i have already exhausted all self help options, meaning i need a real human who can poke into the database or whatever to fix a real edge case problem, who did the calculations to decide these power users (best customers?) can all just die?
I remember watching Andy Barry/MIT demo of Pushbroom stereo approach on a flying-wing drone, it used stereo 120FPS cameras to dodge trees & branches. It's almost a decade later now & such hardware is still not cheaply available for Pi's/SBCs.
I've compressed tens of thousands of videos in recent years and critically looked at the results.

My gut feeling is that implementations of hardware acceleration are just simply not as good as software implementations, the cause perhaps relating to localised resource constraints in hardware when recursing deeper or somesuch.

The algorithms are the same, the chip versions are more resource constrained as the stack goes deeper if you will.

Hardware compressors are much much faster, no doubt, by an order of magnitude and more .. but software compressors left to run slow, with two passes, just produce a much better result.

Standard hardware compressor settings tend to leave moire patterns when the camera pans outside a chain link fence onto a player inside a court (for example), or leaves a blocky halo around the significant figure point of interest moving in an otherwise stillish scene - it's subltle small things that grate when you see them.

The root cause of perceived downgrade in quality is bulk pushing of high quality originals through hardware accelerated compression in order to save time and reduce cost when generating lower bitrate versions to stream.
YouTube recommends encoding master files for 1080p30 at 8 Mbps.

BluRay tends to encode 1080p30 at 50 Mbps

ATSC using 18 Mbps for 1080p30 is quite a lot in comparison.
Yeah. They look at it very close. And they have sensors to look at it automatically. And they also look at the paperwork.
What a surprise to see Chitwan mentioned here. It gives me a chance to share:

My father was from Nepal, and served as a park ranger in Chitwan National Park. I believe this was in the 80’s, before I was born. He always spoke very proudly about that time of his life. One fact he could never repeat too often was that he became an acquaintance of the late King of Nepal, who I believe visited the park on a yearly basis.

He also had a small scar on his arm that he claimed was from a tiger that hadn’t been fully tranquilized. I’ve always amusingly felt that he sometimes embellished his stories, but I’ll grant him this. Seeing the picture in the article of the men surrounding the tiger, is the first time I’ve had a chance to see what it might have looked like. Thanks!
The event lasts months, but as I read, but if you compared the position over the course of more than a week, you’ll notice a difference in position. Sorry if I wasn’t clear!

Odd that the writer called out these words in quotes in the midst of metaphors that were more obvious. I missed the article on the first read through because the writing was so bad.

Anyway, on second read through: amazing they were able to keep teams on this project for nearly five full decades who can still debug this old hardware. Amazing longevity. Talk about maintenance of a code base. 15 billion miles to push a patch. Amazing.
Two and a half!
I find that apologetic behaviour strange too. You own a Tesla, it's a good car, no need to be sorry for its frontman.

I mean I kinda get it? But everyone's doing it and it's weird. It's almost like writing a review of meat and apologizing for eating meat beforehand.
