Not that tiny, n not such little energy, if Intel AVX-512 requires throttling the chip down to 60% of full speed (n similar slowdowns are necessary on Xeon Phi, 1.4 GHz to 1.2 GHz for full) SIMD when using "heavy" operations like multiplication (and also count-leading-zeroes aka CLZ) so it's a lot of energy for sure.
What gives you the impression that California prioritizes homelessness, immigrants, and medicare over education? The state spent $136 billion on k-12 education last year, making it far and away the largest spending program. Anti-homelessness programs typically get 1% that much, although recent years have been slightly more as the housing crisis worsens.
If a game that costs too much and is bad can't be cracked without a lot of effort (Empress) because it has denuvo, I will not buy it.

It doesn't matter if a game has denuvo, if the game is bad and overpriced I won't pay money for it.

In fact, because of piracy, I spent more on games than I would have without.

That means the people who are trying to make a quick buck and turn shit into gold will still not succeed.

When I don't have money I won't buy games regardless.
When I do, I do buy games but I try the pirate version first if something interests me.

In most cases it turns out I was baited by whatever and the game is only interesting for that evening, or I can tell in the first few minutes that it's not for me.

I always have buyer's remorse.
It's really rare that I don't regret a purchase.

With Stream or Epic only having a 2 hour refund window, it's simply not enough.

I knew a professor of physiology who claimed to have spoken with another professor (somewhere) who had actually done some measurements on Miguel Indurain.

IIRC, his resting heart rate was 25. The average human heart at rest pumps ~5 L/min, so his was pushing out ~200 mL/beat. According to the story, his wife wouldn't sleep in the same bed as him because his heart shook the bed so much every time it beat.

Since the stroke volume of the heart is more or less fixed in the short term, the fact that he could meet his needs at such a low heart rate indicated that his maximum cardiac output was in the neighborhood of 35 L/min (max heart rate 175 x 200 mL/beat, he could probably get his rate higher but the heart would not fill completely and so stroke volume would be a bit less).

I have no way to know if this was true, but he wasn't known for exaggerating.
this is not correct

probably it would improve the paper to remove the russian-peasant-multiplication references entirely, or reduce them to a throwaway aside in one place

in part this is because you surely won't be the last person careless enough to make this obvious error

but also it's because russian-peasant multiplication is a totally normal way for hardware multipliers to work, and the main content of the paper is totally decoupled from whether the final multiplication at the end of all the reductions are done with russian-peasant multiplication or (as would probably be a better idea) something like a dadda multiplier or a booth multiplier
I think you're right. It bypasses regulators and realistically it's going to capture the majority share of the fediverse anyway because it removes the complexity of picking a Mastodon instance.
GrapheneOS has implemented storage and contact scopes. Users can set a program's permitted storage environment. Similarly, contact scopes allows users to limit access to contacts that are tagged with a keyword. On my phone the 'special' contact group includes Djimn Hovnbg, with a number in Egypt, Blin Futtum'ch with a UK number, and so on.
Uh, you clearly didn't get the proof. N-bit multiplications performed with a single addition and a single move. Proof involves showing superiority over the number of additions in Russian Peasants.

What’s the draw to BlueSky? I don’t get it. Just based on their invite behavior it feels very walled garden, so I focus on ActivityPub.

We should, I agree. But not everyone wants to participate.

I believe life is wonderful and precious… but it is , by default, misery.

If you do nothing (the default condition) to sustain or improve your existence, you will be miserable. That is the never ending tyranny of imperative action.

That is the fundamental nature of life, and not everyone is up for it. And that’s ok.
It’s not necessarily the reports themselves. It’s cnn and the media at large that take these reports, twist them and turn them into fear porn to fit the necessary mind control narrative. The reports are fine for the most part.

I've used HTMX with Alpine for a backend application, and they help on making the application more dynamic, along with Tailwindcss a lot of the frontend effort is complete.

neither of these comments is correct
I wonder what the demographics of Bluesky are under their longish term strategy of invite-only, and I wonder what it says about the future of digital society.

Given the history of invite-only societies, one or two particular outcomes seems highly likely. Is this the future of social?

For a brief period around 2012/2013, G+ was awesome. It was the best way of following people who shared your interests. If Facebook was for keeping in touch with people you went to highschool with, G+ was for keeping in touch with people you wished you went to highschool with.
See, the big problem is that people who buy into it can't be trusted to talk about it. There are vested interests everywhere afoot. I look this stuff up and there's just more about it from the perspective of the people who stand to gain by fooling me into it. This might all be factual. I simply don't care to take the time to fact check this large pile of jargon. Find me a resource that talks about this, that is also demonstrably not bought into the ecosystem and stands not to profit from it.
Yeah n how much do you get paid, n for what? You get paid to take on professorial duties, TA'ing, lab assistant, that sort of thing usually. Pretty rough in many ways.
> So basically we would like to cut down on using oil by… burning more oil.

For now. Until we build more renewable energy plants. Miles per ton of CO2 is better with EVs no matter how you power the EV.

> And how are EVs more efficient then standard cars if they have less range and don’t work as well in certain climates and can’t go where the electricity is not readily available?

EVs are less convenient, no argument there. But they're still more efficient. Even in cold climates. 90% of new vehicles sold in Norway are EVs or plug-in hybrids.

> We are already polluting the environment by burning stuff for electricity, how does any of this help?

Switch to renewables and then you stop burning stuff. Until then, burning oil for power is better than burning oil to propel cars.

> And where to we get all the chemicals for the batteries and what do we do with them when they are useless?

Tesla recycles 90% of the important metals in their batteries.
If you/we/other folk want it to be a thing, shouldn't we at least try to not frame it as a 'dead in the water' piece of tech?

Seeing how HN has a way of planting seeds in the minds of potential early adoptors, framing it as DOA may be the self-fulfilling prophecy we want to avoid if we want changes to unfold within our heavily centralised social media sphere.
Yeah, I'm curious as well.
Man, I might get behind that if it felt more open. Instead I have to compare it to the thriving ecosystem on ActivityPub and I just don’t have interest in developing on ATP.
All the flaws were due to the one trick pony "make it look thin" era of Ive - the stupid butterfly keyboard switch, the fact it was riveted to the chassis, the poor thermals, the lack of larger sized ports.

And after all that the thing was still heavy.

Electrolysis cannot hit 100% efficiency. Maybe the approximate math can, if you only consider the first law of thermodynamics, but you’ll violate the second the moment it enters reality.

Alkaline electrolysis maxes out at 66% theoretically. PEM is maybe 80% but that’s neglecting system-level losses.

You cannot extract energy from compressed gas if your fuel cell requires gas at that pressure in order to operate.

There is this weird cult of first principles I keep encountering where people think they’ve cracked the code but they just don’t understand systems.
Well of course they are there to help with profits.

Do you think they are irrational?
It is the third gen UI in the making ( Apparently for a few years already ).

The first one is old Reddit, the 2nd is React? / JS FrontEnd based rendering. The 3rd ( "sh" ) if I remember correctly is based on something similar to Livewire / HTMX concept.
You should really do some research on this. Good luck on your journey.
The article brought up other good points, such as the soot from boat traffic accelerating ice loss and the sheer sad irony of it.
Not OP, but for me but for me it eliminates one more decision - naming. I don't want to think about class names or follow a convention like BEM (and probably set up linter rules so I don't do it wrong). I like sscs / BEM in some projects, but it's just one more thing to think about. With utility classes you don't think about it, you style the page as you go inline in the class attribute. The biggest hurdle is learning the utility class names, but there are good cheatsheets for that and my editor already autocompletes all the tailwind classes for me, plus whatever other classes I may have defined.

I think HTMX and tailwind fit well together because I also see HTMX as a kind of "utility framework". It augments the standard html elements with additional capabilities using attributes and HATEOAS.

> simplicity of GNU utils and the expressivity of a scripting language, but doesn't do either of those things better than the equivalent sed/Python etc.

It does scripting and gluing scripts far better than python.

It's not even close.

I'm not even going to address sed, awk, bash and the like.
My experience is exactly the opposite. Most of my social sphere has already moved to Bluesky. Also most of the top posters I used to follow on Twitter have either migrated or post on both. As a result I've been spending more time on Bluesky than Twitter recently. It's the future.

But you are right that while it remains invite-only it is limited. The real test will happen when they open the floodgates.

> All you have to do is read the datasheet and multiply a few numbers to calculate worst-case power.

True story: When I was in college the lab mate I had reversed unknowingly reversed power and ground on a chip on a breadboard. I turned off the circuit and reached for the chip and got a blister on my finger.

Maximum power is infinite in that case (well not infinite, but pretty damn high!) I don't recall seeing a data sheet on power consumption when power and ground is reversed...

No offense, but this comes across as "This was the way I was forced to learn it, and dang it everyone else should do the same." But my experience says, I wouldn't have got a blister on my finger if I had that.
That's a pro. Very good! Now how about you exercise some intellectual honesty and provide some cons as well?
That was my experience with OriginPC, i.e., a seriously messed up build, unhelpful (but friendly) customer service, and terrible warranty.

Wild mammal biomass is estimated to be about 83% lower due to humans. Reduction in biomass isn't exactly synonymous with extinction, but they aren't totally unrelated either.

We're very far apart on this issue. I feel like you must not drink socially, so you're not exposed to the milder effects of alcohol. Alcohol enables both social and anti-social behavior. It doesn't have to be black and white.
If you are not writing S/CSS or styling anything beyond what Tailwind/Boostrap (or other frameworks) already has, then it is as simple as it gets. The last time I was involved (actually writing) in a Tailwind project was in 2018. However, today, I can just look at the documentation and do a design all the way without writing any S/CSS at all.

Most people don't have a rather obvious interface on their units to tests. If you are implementing one of the CS3025 (your university probably used a different number scheme) algorithms, then the interface is obvious and worth a unit tests. Even if there is some doubt (rare), you will have so many users that is isn't possible to change anymore anyway.

Most of us are writing glue code that isn't as clear what the api should be. Unit tests just get in the way of refactoring when requirements change.
Langchain is an obvious VC / investor hustle by a handful of smart developers who are betting on the low sophistication of entrants to ML and Data science.

Suggesting that war, presumably the invasion of Ukraine, is in any way, shape or form, comparable to leisure travel, is absurd.

I'm not sure any part of america has working education; across the board it seems to be a huge money sink that produces poor results. Gesturing to homelessness, immigrants and healthcare is clouding the issue. Those are real, pressing issues too, and it's not a binary choice of tackling one or the other.

> but with a more powerful foundation so you have the flexibility to go further.

The question is: should you?

I like Perl, but it itself has many warts that make maintaining a large codebase more of a nightmare than using C, and certainly more than most modern languages.

I agree with other commenters here that the tools Perl sought to replace are still used more than it. It has its niche of being excellent at text processing, and more capable than shell scripts at that task, but I'd think twice about reaching for it to build anything more complex than a shell script replacement. Especially in 2023.
I hate to say it but the type of folks who are homeless and suffer from mental illness usually have a fundamental incompatibility with society and should be forced into mental illness institutions. If they can be rehabilitated, great, if not, at least they are in a place that can help them and protect society from them.
Oh if it's so easy to debunk my arguments, surely you can link me to a resource not tied into the ecosystem that debunks them? That is, a resource that does not stand to profit from coverage of crypto.
> A few hundred years ago before the industrial revolution the earth or at least part of it were hotter.

Which is it?

Was the mean global tempreture higher ("hotter" overall) or was it the same mean global tempreture with the usual climate cell to climate cell washovers making some a bit warmer and others a bit colder.

The assertion of AGW is that mean global tempreture has been essentially constant for some 200K years and has only recently 'suddenly' started to rapidly change (by environmental stability timescales) over the past century as a result of human activity pulling up billions of tonnes of formally buried carbon sequested in fossil fuels.

Yes and Perl’s Unicode transition between 5.5 and 5.6* was exemplary. There were some speed bumps but generally old stuff continued to work and Unicode support could be added in a straightforward manner. In contrast to how python 3 handled it (not trying to start a language war, these days I prefer python overall). I suspect Larry Wall just understood text processing much more deeply than Guido (makes sense since he is a linguist and Perl was always more text oriented).

*technically it was 5.005 or something to 5.6 because they decided to drop a zero or two
