Decoding a single frame can be done a completely deterministic constant-time basis using hardware acceleration, common in embedded systems.

Decoding two consecutive frames would obviously require two such cycles, which the hardware may or may not be spec’d for. With three, four or n skipped frames, you would require (at least) n frames prebuffering, rendering and graphics memory to guarantee smooth playback.

I think it makes sense to differentiate between mastering formats and consumption formats.

One does not, after all, ship studio masters of albums or songs people listen to.
What should be doable:

Deconstruct a movie into a set of 3D models, textures, voices, parameters for those 3D models' movement, procedural generation of background objects like trees, grass, sea, sand, weather conditions, etc, etc. Like the data that forms the content of modern, near-photorealistic games.

A game engine-like rendering system would then render a scene, tweak parameters until rendered scene / frames match the original movie closely, and work through the rest of the movie the same way.

When done, one could produce derivations of such movie by changing actors' voices, have them move differently or speak in another language, swap out buildings or other objects, reduce polygon count or resolution of textures, have a cornfield show a little taller stalks, put the sun in a different angle, etc, etc.

Of course this is way beyond current compute capabilities. Not to mention software frameworks to do this job. But in theory this should work. For a 2min trailer it would probably be pointless. But for a 2..3h movie, maybe not.

And yes, of course this would be lossy 'compression'. Just more high-level than current video compression schemes.

For an audio analogy: compare mp3 compression with MIDI + quality sound banks for every instrument under the sun + parameters like how hard a piano key was struck, etc. Vary such high-level parameters until rendered output matches the original music.

In Thailand anytime a new SIM is activated an ID check is required. In the past I kept a SIM and I used to just move it between phones. Now when I want to move my eSIM between phones I need to go to the shop with my passport or do a video call with tech support and show my passport to them over the call. Such a pain in the ass.

He debt financed the buyout. While he had to put up a non-trivial amount of his own money he also borrowed a non-trivial amount of money. Part of Twitter's problems today is paying an extra billion dollars a year in interest payments on those loans.
That is a very "pure physics" way to approach physics, and I think it's right if you want to build up the underlying principles. That was how my college taught physics, and it helped to make many otherwise unintuitive parts of thermodynamics understandable.

Also, physicists don't necessarily include fluid dynamics as a core discipline. It is almost mechanical engineering to them. I'm not surprised to see it missing.

I am very sorry if I could not frame my comment better.

What I didn't write explicitly, but vainly assumed that people will read between the lines.

The people I describe also suffer from SLS exactly because what you say.

Their lives are full of bad practices like alcoholism, not seeking medical health, choosing cheap and unhealthy choices whenever possible. Because of the weight.

You described it well. I assumed that people will get it- SLS is a result of helplessness at the extremes.

Another commenter wrote about the role of religion. I also think it plays a somewhat positive role.

At least in my state, days of Brahminical oppression are over. And the role of religion and social rules are positives.

How to Use React with Stimulus on Rails
If you’re using Hotwire in your Rails project (Turbo, Stimulus etc), it is reasonable to wonder if it’s possible to use a SPA framework like React or Vue in the same project, especially if you were building something with a high degree of interactivity. I wrote this article to explore how you might approach this problem if you wanted to take advantage of a framework like React, just on one page (or a few) in your app.
What your son is learning (synthetic geometry) and what you learned (cartesian geometry) are essentially two ways of looking at the same stuff. One emphasises coordinates and one does not.

What the post is about (non-Euclidian geometry) is a rather different thing entirely. Its about doing geometry when the space you live on/in is curved (like doing geometry on the surface of the earth).

Purely anecdotal story, but I will share:

This week was the first time I have gotten COVID, and it hit me pretty hard. Admittedly I have not been especially careful in trying to prevent myself from getting it, so for a while I wondered if I only got it asymptomatically or if the vaccines (I got the OG one plus two boosters) were enough to not get a serious infection.

I sort of wonder if there was a mutation that has evaded the vaccines, and that is what is going around?
> When Apple turned on Adobe, over and over again, I did not understand how "Apple bites the hand the feeds it" .. Adobe was a likable brand.

It was no Quark, but Adobe was never a likable brand, and has always been as much (if not more) of a monster as Apple.

Remember that TrueType was an Apple/Microsoft response to Adobe's behavior around Adobe's monopoly on core desktop publishing technologies. The reason Warnock was on the verge of tears at Seybold in 1989 is because he was forced to compromise on price and terms to keep PostScript on LaserWriters.

Yes, and one should be very wary of someone who speaks in absolutes.

That said, there IS a valid point to be made to highlight the inordinate success of modern physical theories. It's annoying when the only physics news is sensationalist psuedo-science "heresy" from those who don't even know what they're rebelling against. Sean Carrol does a great job of making this argument in an hour-long video "Quantum Field Theory and the Limits of Knowledge - Sean Carroll - 12/7/22": https://www.youtube.com/watch?v=REITVohWOO0

He makes a much more precise, and I think powerful, argument that we actually know quite a lot.
Comparing the market segment of all data centers around the world to a single nation doesn’t make much sense to me?

Not saying we shouldn’t be invested in efficiency here. It’s possible that we need regulation and the natural incentives of cost control aren’t enough. I just honestly don’t see the alarm.
A BFF is just an API gateway that is tailored to a single frontend. It's especially helpful if the frontend is a native application as opposed to a web application, hence why it was a pattern championed by Netflix. If you have some native client out there and you can't guarantee that the user will update it, it's helpful for it to only talk to a single service so in case you want to evolve your backend architecture, you can update the BFF implementation and the existing native app won't be broken by your backend changes.

Having a native app out there in the wild on customer computers that is coupled to a bunch of different microservices is hell for when you want to change your backend without breaking your customers' experience and forcing them to update.
In case anyone else was wondering:

> Power usage effectiveness (PUE) is a metric used to determine the energy efficiency of a data center. PUE is determined by dividing the total amount of power entering a data center by the power used to run the IT equipment within it. PUE is expressed as a ratio, with overall efficiency improving as the quotient decreases toward 1.0.

This is a great explanation. And to me, what sets Datasette apart from a generic SQL UI, is that Datasette excels at publishing _specific_ and curated datasets and allowing interactive exploration in a way that plain CSVs just don't offer.
When I say “web standards”, I mean official W3C standards, and I think we should be actively hostile to corporate attempts to take over that process.

But I disagree that we shouldn’t also try to accommodate quirks. That’s why we have `Array.flat` instead of `Array.flatten` — the standards body decided to come up with a slightly atypical name for the feature rather than breaking a bunch of websites.[1] Our collective history is too valuable for us to be breaking stuff just to make engineers’ lives easier.

> everyone just assumes everyone else knows what they're doing.

It’s not just that. There are practical reasons to choose the bandwagon, even if you know it’s not the technically optimal approach.

If you’re planning on hiring junior and mid level engineers, for example, it’s a great help if they already know the technologies involved. Your hiring pool for React is a lot bigger than for a more obscure tool. Additionally, the popular tools also tend to be stable and long lasting, with good support.

So, there are compelling business reasons to choose what’s popular, even if you aren’t making assumptions about the technical quality just because its popular.
My point is that startup time may not have anything to do with the GUI. It is not a good metric. I could write both an electron and pyQT app that takes minutes to start if it has other shit it needs to be doing. I haven't used electron in years but pyQT apps start up instantly, therefore this app must be doing something else.

If the two apps were programmed identically then you might have a comparison.

Doesn't look like that changes anything about actual dereferencing though, which is the primary thing discussed - https://godbolt.org/z/4vW5Ksnab still emits an "align 4", which llvm could still assume as UB if violated (though I don't know if it ever does).
I am a passive user only reading things related to 1 specific thing and some time ago when logging on I was informed that I can no longer use 2fa for my account because security costs extra. Don't remember the details but it appeared absurd.
Amazing, just found a video where they add a SIM slot to a US iPhone 14. The space is there and the slot just plugs right in. It required removing some resistors (to reroute the data lines from the eSIM to the slot). They didn't even cut a hole in the chassis for the SIM tray; they inserted the card before closing the lid.

This proves it was purely a marketing move which makes the decision even more insane.

Yes, but note that carriers will do all of the above. Use their licensed 'sub-6g' spectrum where traditional cell networks operate; make use of unlicensed spectrum for Passpoint Wi-Fi, use (licensed) mmWave spectrum.

Depending on the venue, they're likely to do a mix of whatever is most cost effective. But more spectrum, if usable by the handsets people actually have in their pockets is helpful.
Plus data centers are low hanging fruit for decarbonization. Everything (apart from diesel backup generators) is already electric, so as the grid de-carbonizes so do data centers.

As you mention, DC operators are already highly incentivized to reduce energy costs, so as wind and solar power continue to drop in costs DC operators will want to fund or buy green power as often as possible.

Getting backup power to be carbon neutral will be a little more challenging in a DC, but it's a walk in the park compared to many sectors. Shelf-stable biofuel is already fairly accessible and using grid scale batteries can reduce the need to combust anything (plus open power arbitrage opportunities).
That’s not to say it doesn’t provide value. Using raw ffmpeg is a pretty technical task, with lots of pitfalls, and not for your average user.
For the most parts your points are good, but the large scale facilities buying up renewable generation resource both hides the true energy cost whilst consuming that renewable resource. I suspect data centres are good candidates for such resource usage since they can be built optimally for generation capacity, but it's definitely possible the numbers could be skewed by the data providers' ability to hide energy consumption whilst having a net global impact.
Hetzner (German data center provider) claims to achieve a PUE of 1.1 (https://www.golem.de/news/besuch-im-rechenzentrum-so-betreib...), admittedly their cloud offerings are quite limited but I think they are expanding on that front. So it doesn’t seem like only hyper scalers would fall into that limit.
Yes, in a maze without cycles the left-hand rule will take you through every part of the maze, guaranteeing that you reach the goal.

Of course in a maze with cycles you might still reach the goal, but it's not guaranteed. For example there's a cycle in Hampton Court Maze, but the left- and right-hand rules both get you to the goal from the entrance.
Sure, housing takes ~20%. But while you are sitting in your nicely electrified house, watching Netflix, You're still using that datacenter's power. All the people in all their nice electrified houses are looking for electrified entertainment served from datacenters, along with all the remarkable shit computers get used for.
So it's not that housing isn't more important, it's that computing does so much with so little already.

It sounds almost like the author is advocating for a really dumbed down BFF layer (backend for frontend) but what they are missing is behind the bff layer you would have general purpose apis. And if I interpret the article to the extreme what is the difference between this pattern and how html is currently served. Salesforce works sort of similar to what is described and it’s a nightmare, these restrictive ideals in my experience just aren’t good in practice because they tend to slow down development.

Not an expert, but can't resist chiming in anyways... One thing to think about it what exactly is causality? There'll be tons of different definitions, but they'll all have one thing in common, events that cause "later" events, and/or events that depend on "earlier" events.

And in a physics sense what is an event? An interaction between two things, right? And since there doesn't exist any force that can interact instantaneously across distance, the speed limit of causality is equal to the speed of our fastest forces.

If we discovered some scifi-esque Tachyon particle that traveled at 2C, we could no longer say the speed of light is the speed of causality.
Hmm, maybe this is a "bug" or some intentional way this measurement is made, but when you view the carbon production over time, you can see that some low-carbon sources like wind & solar seem to vary in proportion to the energy being produced. So these aren't exactly zero-carbon because of production and maintenance and whatnot, but it's obviously very low. However, wouldn't this carbon production be annualised at a constant rate - solar power doesn't produce more carbon the brighter the sun shines (does it?)

It makes sense that there's some lookup of X energy source being Y tons co2 per mwh, and this is probably correct when the vast majority of the co2 is coming from the fuel, and the construction + maintenance etc are a rounding error, but this wouldn't be the case for solar, wind, etc.

I'm not sure about that, naively you could turn the entire cut GOP into i-frames couldn't you? I'm not super familiar with the nitty gritty of h264/h265 but intuitively I think you wouldn't even need to turn everything in the GOP into i-frames. You could trace out the inter-frame topology of the GOP and then replace only the "orphan" frames with i-frames, then the remaining p and b-frames would retain the necessary reference data for decoding.

I would love it if someone who knows more about this than I do would confirm/deny since this is something I've been curious about for a long time now. (Though I would also love a tool for near-lossless cutting that just re-encodes the cut GOP, please link such a thing if it exists)

Killing off physical SIMs is like arguing in favor of soldered RAM.

Because that's all eSIMs are you know. They are not software SIMs. They are physical components with the additional capability of being provisioned remotely by the end user with a friendly UI that sometimes works.

Moving physical SIMs (and thus your service) from a damaged, inoperable phone to a new one takes approximately 5 seconds. This cannot be improved upon with eSIM.

That said, eSIMs have their place too, especially in the industrial IoT space. But completely eliminating physical SIMs from consumer handsets is beyond stupid.

That’s a POV I’ve grown to adopt as I got older (like many, perhaps). I used to heavily privilege theory, believing that everything could (and maybe should) be derived from first principles.

Now I place the concrete over everything else; theory is nice when it can illuminate why the practice works. Otherwise, it’s just words.

The most frustrating is when I have friends who have derived their entire understanding of a subject I know as a practitioner (typically something tech/programming related) from watching YouTube videos/listening to podcasts.

Because they’ve heard hours and hours from experts, they have a feeling of deep understanding. But talking to them about this topic is extremely frustrating because their knowledge clearly has never had to be applied to the real world, and is grounded in nothingness, so they misunderstand lots, but they feel like they know what they’re talking about as much as you do.
I want to think this is an unfair characterization, but it feels all too familiar.
