> For deferring the madd specifically, using two separate sum2 vectors and splitting the `mad` vector into two

Actually, the idea was to accumulate into 16-bit sums, and only do madd to 32-bit every 4 loop cycles.
I'm not sure splitting it up like that actually helps, since the latency can be easily hidden by an OoO processor, and could actually be detrimental adding more uOps.

One thing to note is that you've got a dependent add chain on sum2_v, so using two independent sums instead of one could help.

> Plus I am sure there are many other opportunities to optimize this I have not thought of :)

Other implementations I've seen don't go any further, e.g.
https://github.com/zlib-ng/zlib-ng/blob/develop/arch/x86/adl...
https://github.com/veluca93/fpnge/blob/9a9fc023870bacd06674f...

So perhaps as you allude to, it isn't really worth it.
A megawatt electrolyser fits in a cargo container, so that's not as impractical as it sounds. But personally I think at least for ships ammonia is the nicer fuel.

It seems pretty clear to me that in your scenario Texas wouldn't have jurisdiction over anything that happens outside its border. I'm certainly not a lawyer though and would be interested to hear if there is any precedent that says otherwise.
I'm sure they build in tolerance and even take advantage of this signal, yes. The result is still far from reliable, though.

The smug gaslighting and intentional time wasting after an incorrect identification is the worst.

I think the practice of writing an article-by-press release is worth commenting on. It essentially helps launder marketing into consensus "journalistic" truth.

It is, of course, done because it is far cheaper and easier for a journalist to repackage a press release than to actually do reporting. You are right that it is widespread (which op certainly recognizes, that's their point), and it's not new (not sure if OP recognizes) -- Chomsky and Herman's Manufacturing Consent: The Political Economy of the Mass Media (1988) originally brought this practice (and others) to my attention, along with in general thinking about what mainstream journalism actually does and how and why.

(Because it is in large part, as a standard practice, driven by economics, it's possible it has accelrated as newsrooms and reporting budgets have been, literally, decimated. But that's just a guess).

It is still definitely worth commenting on. That what standard journalism actually does, for the most part, even well-respected outlets, is not quite the model most people have of it, is quite a bit lazier and less reliable than the outlets would like you understand them as.
Yeah Glen can be pretty over the top / grating stylistically recently, but he still seems to be rigorously honest, which is definitely more than you can say for the NYT or Guardian.

moving hydrogen is so hilariously in efficient though.

No, no it isn't inefficient.
I'm thinking Solar is going to be our main renewable energy resource. It sucks for heating in winter and transportation. Hydrogen definitely is a great solution for these problems, just need to improve the efficiency of turning electricity into H.
>I don't really get what Cloudflare did wrong here. Someone tried to transfer your domain name and your registra blocked it because you hadn't authorised it, what exactly was the problem?

Cloudflare refused to engage with the problem, offloading their legal responsibility (for enabling theft and fraud) onto me - the domain registrant

As it was, for a few days (because Cloudflare's developed a reputation of being "trustworthy"), my domains mostly didn't resolve - and not just for people who use Cloudflare's public DNS resolver

I, for one, am not OK with Cloudflare enabling this kind of fraud

I think the energy prices situation is going to be far worse in most of Europe than in the USA, but this winter is going to suck as far as heating bills go.

We'll probably see rebate checks go out, or at least programs to give money to low-income families for their bills, but they probably won't send those out until February or so.

People are going to be wishing for global warming at that point.
Respectfully, the court is a small group of unelected old people. If I do not like the way they think, there is mostly nothing I can do about it.

The court should not be in the business of preserving or expanding rights - it should be in the business of enforcing laws our legislatures create. I would state 'in my opinion' but this was also the prevailing opinion for most of our history (including our founding).

To change this will require constitutional changes as its just not how our country was set up.
>New Delhi [India], August 4 (ANI): Union Electronics and Information Technology Minister Ashwini Vaishnaw on Thursday explained the reason behind withdrawing the Personal Data Protection Bill, 2019, asserting that the aim is to bring new compressive legislation at par with technology landscape which is changing rapidly.

He further said that the Joint Committee of Parliament recommended 81 amendments in a Bill that was of 99 sections which practically, suggested for overhauling the Bill.

The government on Wednesday withdrew the Personal Data Protection Bill, 2019 and has decided to come up with new legislation in view of a large number of amendments suggested by the Joint Committee of Parliament towards a comprehensive legal framework on the digital ecosystem.

Speaking to ANI, the Union Minister said, the Joint Parliamentary Committee recommended major changes in the Bill, which was like rewriting the entire Bill.

“The Joint Parliamentary Committee did very extensive work. They consulted a very large number of stakeholders. After it, the Joint Committee of Parliament gave a very comprehensive report which recommended 81 amendments in a Bill that was of 99 sections, it was practically rewriting the entire bill. Apart from the amendments, they were some 12 major suggestions were there from the committee,” said Vaishnaw.

He said that it was important to withdraw the old Bill to come up with a contemporary and modern legal framework to tackle the challenges of coping with the rapidly changing technology.

Let's see what happens. Personally, most people really don't cares about their data privacy, it only really became a talking point when TikTok started gaining dominance in India cause China is a geopolitical and millitary threat. I don't have any real hopes of them enacting something close to the GDPR ever.
I love to cook. It is a skill I have developed deeply. I can look at what I have in the fridge and throw together a coherent meal even with dregs. I can cook a better meal than all but one restaurant in my entire city, and even that is a close race (it is a small city). I am skilled and cooking meals from a wide range of different cuisines.

There is one day a week that my wife and I both have a ton of meetings. At the end of the day we are both exhausted and neither of us want to cook. We frequently order food on this day. That's not a moral failing.
I mean, I think we know what they meant. Let's not be pedantic when the meaning of their comment is clear.
Nobody wants the current world order
From what I understand, this would allow somebody with reasonable resources to easily crack captchas with a high-end GPU. You could increase the complexity of the PoW, but ultimately you then just end up in a resource race.

Ideally you want an attacker to spend as long as possible using up computation resources, whilst your normal clients spend on average little. I believe you would want a multi-stage approach that involves some human interaction, which is statistically failed more often by computers, and keeps them busy for a long time doing pointless math.

The reason it would have to be multi-staged is that you don't want the attacker doing the computing to realize they are solving a pointless list of problems with no hope of getting a token. A normal user might on average do a -> b -> c, whereas you would make an attacking machine do a -> b -> c -> d -> e -> f, and the not get a token for example. (It would have to be statistically setup as not to encourage the attacker to bail early.)

I think I would make it a slightly RAM heavy problem that limits how many of these problems could be solved in parallel. You would obviously setup the problem in such a way that networking is minimal.

For example, you could send a variation of a Langton's Ant map pre-seeded with random patches for a significantly large map, and then tell the client to run for X time steps, then give you the result in some specific area.

Sounds reasonable, but what if I lost the private key?

Speaking from personal experience: I received 7 emails from them, for various "tag" parts of my email (username+tag@server.example). Two of them - for when I was playing with Caddy server many years ago (well before COVID) - and its "auto-https" feature. There's no chance I still have these keys - I likely `rm -rf`'d whole caddy directory.
Presumably because the supply chain problems have also been impacting non-EV vehicles. Peugeot last year had to switch back to analogue dashes on some models as the electronics for the fancy screens weren’t available.

Batteries are more efficient at storing energy, but I'm not convinced we can build enough of them as quickly as we need to.

Inside HQ: dumb terminal PC's (not laptops) using latest Windows* with all the patches, monitoring and BigBrother tracking of activity. All input ports (USB, lightning, whatever) on the PC are disabled, except for mouse/keyboard.

Probably a pretty complex network topology where specific Ethernet ports/terminals have access to specific networks/applications for the most sensitive things. MAC address from the NIC is part of the authentication in addition to user login/2FA. Physical security to those rooms with keycard plus biometric access. Apply this concept to varying degrees appropriately for each system/team/room. Similarly complex application permissions/security would be needed as well.

* Why Windows? PCs are cheap, after all this is the government we're dealing with here. If they are dumb terminals to apps then they are even cheaper when ordering thousands of them. And the gov wants easy support/training so Linux is likely a non-starter with non-tech people. They're not going to spend $1200+ on Apple laptops per person either.

ZFS is still a little on the immature side; there are sufficient recently-fixed bugs involving data-loss that it is hard to be confident that there aren't others yet to be discovered.

That being said, I do use it on a laptop where losing the data wouldn't be a big deal, but having it easily compromised would be. It was just so much easier to transition to encrypted datasets; the whole thing was done with maybe 10 minutes of downtime.

What do you propose storing it in? It leaks through most materials and makes steels unusably brittle while doing so.
There is a long list of reasons why hydrogen might fail as a truly clean fuel, but it makes sense to get real world use cases in place. 20 years ago it was far from certain that solar power could ever be practical for diverse applications.

Still, I would estimate it will take 20 years to learn if we will be casually storing wind power in the form of hydrogen for random consumer use cases the way we now use solar panels.
No. In order for password authentication to be something a five year old can do by pasting PHP code they found in a Stack Overflow search, that is how it works.

But algorithmically even if you want passwords (you don't in most cases, get WebAuthn for example for web site authentication) you can use an asymmetric PAKE such as OPAQUE:

https://tools.ietf.org/id/draft-krawczyk-cfrg-opaque-03.html

This is quite a bit more complicated than the one line PHP password stuff you pasted from Stack Overflow, but the user's password never leaves their machine, and so the Relying Party doesn't know the password, and yet they can verify that the user does know the password which they originally chose for the site.

A man’s lonely fight to ban private jets
Self-hosting on a reliable VPS is already $5+ per month. Github/Gitlab could easily undercut that. And frankly, users should start getting used to paying for software, at least it's better than having your data sold out. I'd be willing to pay $2/month to keep all my repos online.
It's not entirely trivial, it takes work. If you are simply changing the number but ask the inverse of x mod y every time you didn't win the game. 2 out of 3 times changes nothing.

I had the most fun with multiple choice tests. I took the average A,B,C and D answers from previous tests. The teacher not paranoid would have a lot of B, slightly less A and C and below average D answers. The paranoid teacher would have perfect distribution. The supper paranoid used some kind of RNG which also comes in patterns.

One of each type came to ask me how I did it at the end. The last one was funniest. He had one test with a trick question that everyone got wrong. It just didn't have enough C. One of my answers was more likely wrong than right. I had to go over the A,B,D answer candidates a few times. Reduced the list to 3 potential trick questions. Figured out that 2 of them were correct. Don't ask me why but the remaining one must have been C.

He explained how over his [long] career he started out with to few D answers. I name the other teachers still doing that. He then went for the perfect distribution. I name the teachers still doing that. And now he thought he had the perfect formula. How am I suppose to fix this?? He asked. I'm like, I'm not doing your homework but I do foresee a very interesting meeting with the other teachers.

edit: I did study but cheating was just to much fun. When they switched to tests on computers I made a good bit of money as administrator. I swapped some of the answers around so that the wrong answer was right and everyone got poor grades. They would purchase the list of correct answers from me. Then after they aced it I would reduce their grade to something sensible for the student. When they protested I told them that they paid for answers not for grades. Grades are very expensive as -hey- they could potentially ruin this good thing I got going here!
I agree. I immediately associate this with "show-off computing", which would probably look good on brain-dead TV shows about l33t haXors or "Anonymous" documentaries..but what's the point of slowing down your terminal even if it's just by 0.000001 seconds per keystroke only to look at Emojis? Will get old very fast.
What really hits me here is the weight of the fuel cells, at only 31kg (+ container) for 400KM range.

I just used a Huawei phone for like 2 year without GMS, but you and I are not 99.999 of the general phone users out there.

I used Aurora store to access the Playstore, youtube vance to play youtube movies.
For the rest i only use Facebook Messenger(for family), whats app, Telegram and my banking app doesn't need GMS to function. Those messenger app have their own notification services so not completely dependent on GMS stuff. For the rest i'm more interested in camera specs and not really in mobile app ecosystem outside of those couple of apps i just need to talk with family and friends..

It is totally doable but don't think 99.999 of the phone users will take the effort to find everything out.
I think you’re reading one of those exercises right now!
My guess would be that it should be a similar process to how you handle creating a new certificate if your private key is compromised / gets lost.

You probably would need to reauthenticate via DNS, create a new private key and then do what you wanted to do.

Sure :)

96% of H2 produced from carbon sources.

How far do you think we can stretch electrolysis efficiency ?
So far we are at 50% https://www.linkedin.com/pulse/actual-efficiency-electrolysi...

And you need to compress H2 even more to make it interesting to transport, making it even less efficient.

But lets follow our technical dreams where we will have 90% of H2 produced by solar panels (that doesn't have any impact on their own).
Machine Learning Datastores Are Coming
We had the “test of knowledge”, which if you didn’t pass (multiple attempts), you didn’t pass the course.

It was 60 questions in 180 seconds. No hard calculations, just stuff you were an embarrassment to the prof if you passed EM and didn’t know.

He gave it right before break (3 hour class). I got a 96 first attempt. Next highest grade was a 30. He said I could leave as the remainder of class was to go over the test. I literally strutted out and said I was going to have a cold beer. Good times.
Reading this thread is a good example.
Personally I'm terrified of having to spend a portion of my life alone. I've spent my adult life (25 years) with a romantic/domestic partner, doing everything together. I don't spend time with friends in the absence of my romantic/domestic partner. Once, during those 25 years, that relationship ended and I lived alone for a while. You should feel free to laugh at me and say this paragraph is hysterical or lacks perspective, seeing I was perfectly free, but it felt like prison. I completely failed to handle it. It is very hard to contemplate the idea of my partner's death in the future, and attempting to live beyond it.
Bear in mind, inconveniencing 4.8% of users, does not map identically.

No, why do you think it is? You can do science in an educational setting, and education often relies on results from psychology or biology, but it's not a science.

Some would argue that educationalists often experiment on children, but that's not the goal (and of course that's a minor aspect of education).
