While JPEG XL is awesome if measured with DSSIM, SSIMULACRA 2, Butteraugli or human viewers, JPEG XL is an average or bad codec if measured with AOM's current image quality metrics (MS-)SSIM, PSNR and VMAF(neg).

AOM's image quality group is not receptive to adding new image quality metrics. I proposed it, they told that they want to rather reduce the number of metrics, not increase.

To accept JPEG XL as an intraframe they would need to have political will for it -- to deviate from they usual image quality procedures.

JPEG XL seems to give an extra 10-15 % of density on average, but it cannot be measured using the current AOM processes. If it had been possible, they would have already based AV2 on JPEG XL keyframes instead of AV1 keyframes. They are hunting a lot of small improvements, even 1 % improvements, with substantial effort.
I agree 100%

My high school had a phlebotomy track after you took anatomy physiology and I was able to get good enough to get my first job at Scott & White here in Texas. I then used those skills to work 30 hours a weekend (Friday - Sunday) to pay for college. The hardest part was the field work, nursing homes, if you could not get the blood there was no backup like at the hospital so it typically forced bad techs to go hunting for a different job. I would go home and practice on various speaker cable to get the feel for hard veins. This job was filled with pride, challenges, character building traits, and it paid the bills. $17.5/hr back in years 98->20, was far better than most of my friends jobs. No complaints here and a lot of respect for the craft.

Without this job I likely would not have been able to start my software company 22 years ago.
What exactly do you mean proper “dark” themes? Being able to swap to coding in light test on a dark or dark text on a light background goes back to at least windows 3.11.

Solarized dark theme to me looks just like several other similar themes that predate it ex: https://superuser.com/questions/156979/how-to-i-use-textmate...

But I assume you have something specific in mind here?
While what you say about Lua is true, undefined variables can be promoted to errors. An `__index` function can throw an error if a slot looked up on a table is nil, and the environment is just a table.

That's Lua for you. The semantic model is dead simple and easy to understand, and even though roughly no one wants typos to become variables, the semantics would have to be less minimal to accomplish this.

So instead, there's a mechanism, a more than adequate one, but one does have to use it.
For non-niche use cases that is a bad developer experience.

If you are designing your own solution that uses protobuf instead of JSON say goodbye to a range of useful tools that the whole industry uses. From testing to automation it will be harder at every step, and you will have to find custom solutions instead of usual no-customization solution that works OOTB with JSON.

It is a good way to frustrate your developers and generate sometimes brittle solutions related to testing/automation/infrastructure.

> Physics does not answer why questions

Well it does, but often it takes a more fundamental theory than where the question was posed.

On the other hand, an answer may involve logic and/or a mathematical derivation which is not so different from calculation, so where intuition ends and “shut up an calculate” begins is not all that clear and may depend on the level of expertise.
>Agree that you shouldn’t swim with your phone, but Apple not covering liquid damage is a business decision that doesn’t tell me whether the glue and gaskets serve a valid waterproofing purpose.

What will you define as "valid"?

Using logic I can only conclude that glue is not used or is not effective for water proofing OR there are as you called "other business decision" involved here.

Your alternative means that glue works but Apple uses the water detection stickers to refuse warranty in bad faith, the battery exploded because it was a bad batch => the water sticker is red, sorry no warranty for you!

Anyway the phones are not in reality water proof,so this excuse should not be used by fanbous, let Apple lawyers use it, they are actually paid for it and might even know the reason it is used.

What I'm interested in is what's referred to here as the 'recent studies'. Medical research is important here because there have long been concerns around electromagnetic waves causing cancer, but none to my knowledge have held up. Such as living under power lines or near radio stations, cellphones. That's not to say the radio jamming in this case is not using a dramatically more dangerous method.
Note Popper's definition of the intolerant in this context: those who do not engage in rational argument, and those who forbid their followers to listen to rational argument. Neither applies here.
The challenge isn't the storing of the flag that says which sensor it has, it's testing the combinations, training for the different scenarios, treating the incoming data differently, and so on.
Can you please elaborate on why one is better than the other?
I hope you would, and unless you happen to live near a major political center or a military installation, I think your chances would be very good. A nuclear war would be terrible, but it's not a doomsday scenario.

In the last months, we've seen how the Red army performs in conventional war. They were supposed to have 10,000 - 14,000 tanks, including modern ones, but we now see that they barely had any modern tanks and that after losing 2,500 tanks from the 60s, 70s and 80s, they started begging Belarus for their old tanks. They also claimed to have a modern air force, but until now, they have been unable to establish air dominance against a country that barely had any air force. And they were supposed to have a navy, but also that was an exaggeration. They claimed to have precision-guided missiles, and even supersonic missiles. They ran out of those long time ago, and they weren't that precise or fast. What they had was a lot of empty posture.

Why do we believe that they are any better at nuclear war than they are at waging conventional war? Whatever is true for a simple conventional war, is even more true for a nuclear war: Their missiles and warheads are old and unmaintained, and far fewer in numbers than they pretend.

The effects of corruption runs so deep in their society. Just like you can't buy any complex Russian products in your local stores, and just like you never wanted a Russian car, Russian military is completely incapable of successfully waging war against the West.

Can Russia launch a nuclear attack against NATO? Probably, yes. But it would be much smaller than the official numbers suggest, and layered Western missile shields would intercept a percentage of those missiles. Some missiles would miss their target and some would not detonate.

Different studies give different estimates ranging from tens of millions to hundreds of millions dead in the immediate aftermath of a strike, but studies assume that Russia is actually capable of carrying out a strike and penetrate our defenses with a large number weapons that work. Estimates of dead afterwards, are usually from starvation, not from radiation.

It's been 40-50 years since Russia actually had strength comparable to NATO. Even back then, humanity would have survived a nuclear war. Nowadays, both Russia and the free world has fewer weapons, and we now know that Russian military capabilities are routinely exaggerated. A nuclear war with Russia would be terrible, but it would be over quickly, it would end in Russian defeat, and most of us would live on afterwards.
?! Java doesn't offer a reasonable solution for files... it is presumed they can be closed by the garbage collector calling "finalizers", but that results in problems such as holding file locks long after they should have been released (which is a correctness problem) and running out of file handles (a limited resource that Java does not track pressure against) due to this mechanism having no time horizon.

The result is that you are essentially trapped into the realm of manual resource management, having to put a try block around every single use of a file to make sure you can control its lifetime and prevent it from "leaking" into the collector. You then would have to use a finally block and call close. Memory is certainly the easier problem as it is a single constrained resource with usage semantics (licenses and conflicts) entirely constrained by the language.

(They at least have recently added some syntax that makes the last bit of that easier, but which doesn't at all make it less manual. This syntax is somewhat based on C#'s using blocks, a feature which I might have actually caused due to some strong advocacy surrounding this issue when .NET was in beta, and yet I have always insisted this syntax failed to correctly understand the problem as, even if you buy into the manual-ness of it all, it leads to colored objects, as there are objects controlled by the garbage collector and objects controlled by using and now adding a field to an object that must be disposed flips it from one regime into the other regime without causing a type incompatibility.)
JPEG XL ISO Spec -- it is a good idea to take a look at a more recent version than the committee draft in 2019 -- it evolved quite a bit
There's no data but to the best of our scientific knowledge, this is how the universe works.

Life is hard. We know that because it took billions of years from the first self-replicating molecules to us. We also know there are things happening in our solar system that wiped us out. We know we could have wiped our species out ourselves.

The "great filter" is one theory to explain why on the one hand we should be observing other civilizations, but we don't. Also they don't need to use Dyson Spheres exactly. But before they start expanding in earnest, they would have a measurable effect on the emissions coming from their star, as perceived from other stars.
This will sound a bit flippant but what's the alternative to appointing leaders by popularity (aka voting)? All systems are prone to corruption, it more depends on the safeguards within the system that prevent it from being abused.
Political or not, thank you so much Drew for banning these vile crypto projects on sourcehut.

There is no room for them and I respect your position.
Okay, I get your point. Speaks to the organisation's basic lack of honesty, which is arguably the real problem here. That's come up before – a recent poll among Wikipedians judged the WMF's fundraising emails "unethical and misleading":

Not a common need but I appreciated the larger supported size (over the 65K limit of jpeg). Once I hit the limit with jpg I switched to png, since JPEGXL is not yet ready, and had to resort to png optimizer to get the size to something close to jpg. So I was looking forward to JPEGXL.
Symmetry is “handled” by Group Theory which is rather involved.
The Sun will become a red giant in 5 billion years - we not going to get off this the rock - which is a good thing for the universe I reckon.
Only, having the possibility to use such sensors isn't the same as actually using them.

Most advanced sensors are exceedingly rare and consequently locally far too restricted to be useful in this context. Social hurdles apply.

The most comprehensive sensor network on earth belongs to the US military.
In spite of being provided extraorinary amounts of taxpayers' money for this, the resulting data isn't shared for common interests like science at all.
I don't work on cryptocurrency projects but this arbitrary decision doesn't instill confidence in sourcehut. Very little upside, huge potential downside. Strange business decision. Aren't your users there because they prefer "freedom"?
Sending a probe takes very, very long, and is just as expensive, so it seems even less likely to arrive than a radio signal. And we might not even notice either one if it gets here.
Looks like saying "where is the fraud there is bound to be embezzling" is on the money again.
>Once you hear it, a good driver will immediately slow down and pull to the side, or delay movement to give space for the vehicle.

Robotically performing an action in response to single/few stimuli with little consideration for the rest of the setting and whether other responses could yield more optimal results precludes one from ever being a "good" driver IMO.

"See lights, pull over" is not going to cut it. See any low effort "idiot drivers and emergency vehicles" type youtube compilation for examples of why these sorts of approaches fall short.
Non apple phones had this a bit longer which is not as long ago as Nokia phones.

That's not entirely true. My Galaxy S8 has a user-removable SIM tray, and yet it's rated IP68.

Water has some viscosity, so it won't flow through tight gaps unless appropriate pressure is applied.

Also they sound extremely localised. As someone outside extremely wealthy and rich USA why should my money go to that sort of political organizations there. Why don't they use their own money for it?
Wikipedia is basically the Wikipedia volunteers. Anyone can volunteer, so unsurprisingly some of the volunteers are "odd".

This article is about WMF, which is run by paid employees, not volunteers. They reflect the political posture of their employer, not the consensus of the Wikipedia volunteers.
My Galaxy S4 was thinner than my subsequent iPhones, and had an easily removable back and battery. That said, the battery life was pretty bad, so that was a necessity.

Wonderful 101 does it beautifully, entire game was designed to use it in many different ways.

The best overall use is the Nintendo DS emulator. Unfortunately only few games are available for purchase but with a bit of hacking the compatibility is great.
HTTPS adds a tremendous amount of overhead to give you messaging. It's a lot better from a hyperscaler's perspective to replace TCP and not use the byte stream abstraction. After all, networks send messages. It's silly to throw that away at one layer and try to get it back at the next layer.
I use Alabaster[1]. Contrary to most themes, it is quite minimalistic and it emphasises comments instead of de-emphasising them. I like the minimalism, because it lets me focus, instead of marking every single thing on the screen as a different colour of “important” making my head spin.

Hi, thanks. Thought it might be so. Still...

RADAR can have high(er) angular resolution with (e.g.) phased arrays (linear or not) and digital beamforming. I guess it's the way the industry works and it wants small cheap composable parts, but using the full width of the car for a sensor array you could get amazing angular accuracy, even with cheap simple antennas. MIMO is also supposed to give somewhat better angular accuracy, since you can perform actual monopulse angular measurement (as if you had several independent antennas). There's even recent work on instant angular speed measurement through interferometry if you have the original signals from your array.

And with the wavelengths used in car RADARs you could get far down on range resolution, especially with the recent progress on ADCs and antenna tech.

I'm not saying you're wrong, you're describing what's available today (thanks for that).

Wondering when all this (not so new) tech might trickle down to the automotive industry... And whether there's interest (looking at big fancy manufacturers forgoing radar isn't encouraging there).
Do you mean the clients connected ? Most DC's I know are firewalled from the internet basically on an internal company network. If you want to get group policy updates and suchlike you connect to the internal company network via VPN.

If you are talking about how the DC itself gets updates then it has outbound access normally via a proxy server or something like that.

You wouldn't put the DC on the internet that would be really insane.
REST is not an "API framework" as usually understood, because "API" generally means "interface based on procedure calls," while REST prohibits interfaces based on procedure calls.
From the page:

> One shall write a program that compresses string "AAABBAAC" to its compressed form "3A2B2A1C".

Interesting programming exercise. Although, the resulting string in the example is still the same length. The "algorithm" could be improved slightly by skipping the number for one-character substrings, e.g. "3A2B2AC"

Cryptocurrency mining, naturally.
> That one can only logically assume there are beings to which we in turn are "tapeworm complexity" (also a thought: maybe we all live right now in such a higher being?) and hence will never be able to perceive them for what they are.

Indeed. Does an ant know that it exists as part of a larger organism? Perhaps we are part of a larger organism, at which scale, our individual human lives are of tapeworm complexity.
Friend, I submit that you and I were both taught poorly. I think you will find this video [0] extremely helpful. It provided me with the missing piece for understanding the need for complex numbers, and what we're actually doing when we manipulate them.

While I enjoy protobufs, it's one of those things I feel I have to re-learn every time I write a new implementation. Never quite get to grips with them in the same way as, say, regex.
I'm highly suspicious of the fact that other life forms in the universe necessarily resemble our own, although I tend to think about some things that seem to be universal like the the laws of physics and organic matter. I'm not yet very convinced that the whole organic machinery revolving around RNA/DNA is universal, although I have a very deep feeling it is...
In any case, "The Caloris Network" is a reference example for me when attempting to think about how different alien lifeforms might be.

Is intelligence necessarily organic matter based? Maybe not. Maybe somewhere in the universe a spontaneous self-replicating turing machine appeared. Maybe there is life on the event horizon of a black hole, or maybe a hot type of intelligence lives inside a star.

I think we can make all kinds of wild assumptions.
I don't like ant colony analogies because I think there is a meaningful difference between a life-form entirely unable to communicate high-level abstract thoughts and those that are - even if it's relatively simple.

For example we view apes as "lesser lifeforms" to ourselves but we still try to communicate with them, and they communicate back to some degree. Or a more extreme example would be dogs - we communicate with them all the time even if they don't have anything that interesting to say back to us.

I'd also argue we still take significant interest in ants despite the fact they're unaware of us. And if we thought we could say hi to ants via pheromones we almost certainly would. The mere fact we keep records of all the species we find on Earth and try to understand them in great detail despite them being much less intelligent then ourselves I think suggests aliens would probably at least have some interest in us, even if we're not that interesting.

And even with ants it's clear we have a lot to learn from them. Ant colony optimisation algorithms wouldn't exist if we didn't take an interest in ants, for example.
You wouldn't construct a solid shell, but a swarm of more-or-less freely orbiting modules.

It seems to show evidence for subsurface ice on Mars now, though I'm not sure if this is H2O ice or CO2 ice.

Reimagining Tutankhamun as a Warrior
There is nothing wrong with you being disappointed, but it is important to clarify that disappointing you does not mean that the service disappoints others.

After all, there is nothing inherently wrong with people having different ideologies, and that must apply to companies too - either the ideology of the owners/operators, or the jurisdiction they reside in. And considering how the vast majority of cryptocurrencies are indeed just vehicles of scam and speculation, I find it perfectly reasonable to just have to send a short message to give a heads up that you are indeed the 1 in a million case worthy of exclusion. Talking to people is not the end of the world, and I doubt it would take more than a short message.
OK. We literally repair these for a living. You and I may have differing definitions of “glue”, but the water seal gasket is not what I would call glue. It is a sticky gasket that is peelable and removable. It can be replaced, and in fact we replace it when we do repairs. Think of it like double-sided tape.

If you watch videos of people doing iPhone screen replacements, you can watch them peel it off easily and then replace it when they put the new screen on.

I am a bit surprised that someone would want to argue with a person who runs shops that do this for a living, but maybe this explanation will help other folks understand.

Also, I can’t reply to your other comment, but the iPhone 14 that is sold in the United States does not have a SIM tray.
Might be time for some state sponsorship to have the beamforming asics, fpga designs for these bands. Although I might be missing something: once you're back down in your demodulated sampling frequency, your old beamformer should suffice? Or are we talking 'adc+demodulator+filter+beamforming' asic?
