There's only so much district heating that is needed. And mostly only in the winter. You'd actually need more energy for cooling in the summer when nobody wants to heat their place. District heating is a nice creative solution for waste heat. But there's a limit to how much of it you can use and how practical it is to use it. Mostly it's still waste heat that's going to be wasted (blasted straight into the atmosphere and space).

And we don't have to burn stuff. Which is why coal and gas powered electricity generation is a bit under pressure in most markets. There are cheaper and better ways to get energy now.

This check will likely be the best for english text/code. You can check in varying size chunks depending on how common you think non-ascii will be. If its ascii you can move 128 bytes forward on avx2 in a couple of cycles.

Recently Marvel Rivals came out and became really popular (developed by Chinese studio NetEase Games). Other than that, there have been talks about Ubisoft going bankrupt and being sold to a Chinese company, but those are rumors as far as I can tell.
The problem isn’t the necessary fluff that must be added, it’s how easy it becomes to keep on adding it after the necessity subsides.

Google was a more honorable company when the ads were on the right hand side only instead of tricking you in the main results. This is the enshitification people talk about. Decision with no reason other than pure profit at user expense. They were horrendously profitable when they made this dark pattern switch.

Profits today can’t be distinguished accurately between users who know it’s an ad and those who were tricked into thinking it was organic.

Not all enshitification is equal.

> And before anyone says it can't grow forever, it's unsustainable, etc... you're not thinking big enough. Just google kardashev scales.

log((mass universe * c^2)/(20 TW * 1 year)) / log(1.025) = 4600 years for 2.5% power consumption growth to exceed the rest mass of the universe per year: http://www.wolframalpha.com/input/?i=log%28%28mass%20univers...

Even if we had a warp drive (which may be impossible), we'd have to invent a free energy machine to sustain 2.5% growth for as long into the future as the earliest Egyptian pyramid construction was into the past, and also an infinite dark energy source to keep the universe from then collapsing into a black hole.

At least for me, there is still benefit in being able to load only the list of articles. Attempting to fetch the full HTML and scrape it can be error prone and may not even work depending on how the site is using client-side rendering.

Microformsts, which give us things like h-feed, are useful but the author is already thinking about the feed reader use case. Why wouldn't they also hook up an RSS feed?
To be honest, I don't like initiatives towards a "verified web" either, and am very scared of the effects on anonymity that stuff like Apple's PAT, Chrome's now deprecated WEI or Cloudflare's similar efforts to that end are aimed at.

Not to say that these would just cement the position of Google and Microsoft and block off the rest of us from building alternatives to their products.

I feel that the current state of things are fine; I was eventually able to restrict most abuse in an acceptable way with few false positives. However, what I wished for was that more people would understand these tradeoffs instead of jumping to uncharitable interpretations not backed by real world experience as a conclusion.

The "western tech executive" is a propaganda mouth piece. This entire situation is reeks of political manipulation and dishonest voices from every single media pundit. Tiktok is merely a break in the wall to wall American Media Nonsense, and the proponents of the continual American Gaslight don't like a break in their manipulations.

Sadly, this is just another example of "A lie can travel halfway around the world before the truth puts on its shoes."

That doesn't mean that every sensational thing is a lie, but verifying the truth definitely takes time!
I can no longer send money to the EFF due to their obvious misreading of the situation. They will lose $100s/year from me, I hope it was worth it. Clearly, a naive take that doesn't understand the nuances related to Tiktok's situation.

Tiktok can still exist and keep showing their garbage to Americans, but it can't do so while being owned by a foreign adversary that attacks us almost continuously.

Sure, they can still buy our information elsewhere, but this is like saying I shouldn't put a lock on my door because thieves can break in through other means. Just check the looting happening in Los Angeles as a result of the reduction in the barriers for theft. Cost matters and if we increase the costs for China's data theft, their ability to steal from us will be reduced.
> Tesla's charging infrastrucute is a competitive advantage.

Tesla's charging network being closed is detrimental to EVs.

Closed, incompatible infrastructure is dumb infrastructure. Closed, incompatible infrastructure is backward and primitive.

As a self respecting car buyer you should actively select against brands that try to lock you in and brands that try to shut you out.

What you want is smart infrastructure. You want to demand that all brands of EV can charge on all brands of charger with no dumb charging accounts.

The good news is Tesla chargers work with non-Tesla EVs. They've been open to all EVs in Europe for years. They're open to all EVs in Australia. Tesla has even started to open them to all EVs in North America.

It works because Tesla has adopted the CCS charging standard in North America (just like Tesla was already using in Europe and Australia). NACS is CCS charging with the J3400 plug. J3400 is the third plug type CCS supports.

Here's a Chevy Bolt charging on a Tesla charger in California. It works because it's CCS: https://www.youtube.com/watch?v=Yu0HDdB9b2k&t=340s

It comes down to a push versus pull architecture. RSS is pull based, you aren't notified when a feed is updated. Most people today want push based with a feed, with all the bells and whistles of a social feed that is updated instantly.

Federation comes in mainly because push based systems require a server managing who follows who, what is posted, and who to notify of updates. That's a lot of information for one central service to be responsible for, leading some to think its better to federate and trust a bunch of servers to host copies of some or all of that same data.

Auto-Remediation Is Important
Sitting on the front page of HN with a good read, and what is ultimately company promo and a careers link seems like a job well done. It made me read/click.

Yes, building a physical DC is much wider scope than colo. This is one part of that, which is also still interesting. The world is built on many, many layers of abstraction which can all take lifetimes to explore. There are non-devs who enjoy learning about software, web-devs who dabble in compilers, systems programmers curious about silicon, EE's that are aspiring physicists, who in turn peek into the universe of pure path (cue yes, that xkcd you're thinking of).

A 'full stack' overview of a standalone DC build still has to set a bound somewhere. This was an approachable intro and look forward to reading more from the layers you operate.

Less than 3% of the water reserve was available, as the reservoir for the area had been drained to repair its covering since last Feb. It was not necessary to drain the reservoir to make the repair. The repair should have taken a couple of weeks.

The fire department was not informed of this ahead of time, and so made no preparations in the lead up to this predicted event.

How do you fight a fire with more than 97% of the water unavailable?
While Intel has LZCNT and TZCNT (leading-zero count and trailing-zero count), which replace the wrongly-defined BSR and BSF, only since Haswell (June 2013), AMD has LZCNT since Barcelona (September 2007) and TZCNT since Piledriver (May 2012).

The author has made the mistake of not using the right compilation options for the CPU, in order to enable the use of LZCNT and TZCNT, because it is very likely that the author uses a CPU that supports these instructions, unless it is an older Intel Atom CPU, up to Tremont.

Had the author compiled correctly the program, there should not have been any branches since the beginning.

When Intel has added the BSF and BSR instructions in 1985 to 80386, they have made a very serious mistake in their definition, despite the fact that they should have followed the example of much older ISAs, where these instructions were defined correctly.

AMD has defined LZCNT and TZCNT in order to correct Intel's mistake, but in order to ensure backward compatibility, the corrected instructions use an additional prefix that is ignored by older CPUs, instead of using a new encoding. This makes the encoding of these instructions much longer than it should be.
Making featureless metal balls seems very easy, they have only one dimension and are perfectly symmetric.

It's pretty simple, the Tiktok algorithm recognizes the value of long term user satisfaction of it's users, and all the American Tech Algorithms are blind to anything long term, and plus the "user" is not the customer in the American tech product, the advertiser is, American social media is a product for the advertisers and not for the users. This is clear as day.
I'd be curious how you define podcasts and radio shows if you don't consider the distribution method. I don't see much light between the two other than the fact that a podcast show list is distributed via RSS.

Just for reference:

- 21% of adults in the US are illiterate in 2024.

- 54% of adults have a literacy below a 6th-grade level (20% are below 5th-grade level).

I would argue than everyone who is stuck a below 6th grade understanding of a language they use everyday can hardly be tech literate ( which in itself requires good reading and abstraction capabilities)

Is it their fault because they choose to be like this? Their parents? Their goverment? Nature gave them the wrong genes? Society shun them for their skin color? A bearded white guy in a cloud chose to ruin their lives?

Don’t know, don’t care, but demanding agency to all adults feels a bit narrow minded, selfish, and not too thankful for avoiding a few external barriers that other humans have to endure…

most of us here skipped those challenges, and ignoring how much headstart we got by sheer luck and no own merit is a bit inmature, IMHO.

Opinions are like noses: everyone has one, and almost all of them are unremarkable and irrelevant to other people. This is my nose.
I love RSS and I actively used it until modern browsers dropped support for it and then websites stopped using it. I always felt RSS being dropped wasn’t the choice of users but more a conspiracy between those browser developers (or rather their managers and company leaders) and marketing/sales departments of pretty much any company that advertises on the internet: Google being the main one.

Why? You can’t bombard RSS with advertising like you can on browsers and if people could get the information they need from RSS they won’t see ads.

I recall the dropping of RSS happened over 6 months to my recollection. RSS was here and every website of merit used it, then all of a sudden Chrome, FireFox and Safari all dropped RSS support. You could go and install a separate RSS client but few people did that (extra steps and all) and then websites saw no one was using RSS and dropped support.

RSS was particularly useful for browsing jobs for IT contractors. I used it daily, using RSS I was able to get job listings fast and apply before other candidates.

True. Though they've moved up in the world since then. They now have their own semiconductor fabs. Chinese industry of today is way more advanced than the China of the 90's making low margin nick-nacks.

By that logic, every single Chinese company is controlled by the CCP by law.
What I learned from this thread is that in the US, apparently, the government is preventing insurance companies from raising the rates, because the rates corresponding to actual risk and damages would be stupidly big, insurers have no choice but to quit the market and then even the wealthiest homeowners can't get insurance at any price.

So what's stopping insurance companies from inventing some kind of fractional insurance? I.e. if insuring a 200sqm house at real rates would be stupidly expensive to anyone but the top 5% wealthiest owners, then instead of quitting the market, why not create a policy that insures the whole house but covers only N sqm from it, priced at real rate / sqm, and it's up to the buyer to decide on N? This way the wealthiest would still have access, everyone else would sort of have it on paper, but it would create space for innovations (and "innovations") in figuring out how to cover the whole thing for regular people - and long-term, incentives for better building and moving elsewhere.

Markets have powerful mechanisms for changing peoples' behavior, but don't work at all in binary "take it or leave it" situations.
This is what I use as well. It's not perfect but it's the best I've tried so far.
Oh wow, did not realize Minetest rebranded. I guess to avoid legal troubles?
IT IS a worn out stereotype. I'm also European and here the doctors are also limited by the national health insurance company on what medication and treatments they can prescribe you due to cost reduction pressure. Their hands are also tied except not by a private corporation but by the government.

Often you'll encounter the infamous "these tests or procedures aren't covered by the national insurance anymore so you'll have to pay out of pocket", or they're covered, but the nearest appointment on the national insurance is 15 months away, at which point you'll either get better or you'll be dead.

My boss recently moved from Germany to the US and was pleasantly surprised how much better the diagnostic, treatment and medication options are for his child who suffers from some rare mental disorder that's basically ignored in Germany by comparison. US seems to always be on the cutting edge of medical research and treatment which of course comes at a cost since research is very expressive.
This reminds me of timing side channel attacks in general. With VUSEC (VU University Amsterdam) we did flush/reload side channel attacks. I don't remember the specifics, I did this in 2018.

But yea, basically if a cache hit versus a memory roundtrip will result in different time values, then you can iterate over all 256 bytes (assuming ASCII) and when you have a cache hit for a specific value, the time should be much lower.

However, this also assumes you understand cache internals of the specific CPU and it means you need to know when caches fill up, why they fill up and how to do cache eviction. Knowing how to do cache eviction means that you need to know how many elements can be cached, and if I recall correctly that means you need to reverse engineer the cache size of the CPU. But once you can reliable evict values from the cache set and reliably fill them up, then the rough outline I mentioned above is possible.

Again, this is like 50% accurate since it has been a long while and I currently work in marketing as a data analyst (I like a mix of fluffy marketing/psychology talk and being deeply technical - if you feel the same way, feel free to reach out. My email is on my profile). There's some of what I described on this website (and a whole bunch more) [1]. I think the reverse engineering of cache lines was specifically in the accompanied paper.

Can we get over the nonsense that banning tiktok has anything to do with free speech?

Companies get shut down or penalized whenever they break laws or behave in obviously abusive ways. Tiktok was given several recourses, and they refused.

That's all there is to it.
The scraping issue is resolved by just putting the `h-feed` attributes on the relevant HTML elements. Far easier to implement and maintain than RSS. Maintaining a parallel XML endpoint is itself very error-prone, I know this from unpleasant experience. The only drawback to `h-feed` I can see is that the feed reader must fetch a larger initial payload. Seems like a small price to pay for much easier implementation and maintainability.
TikTok's algorithm is also nearly instant.

From time to time it will show you content adjacent to what you watch. After three or so viewings your feed will add the content you watched/engaged with regularly.

Press "not interested" twice (or sometimes once), and content will disappear.

American social media effectively ignores any input from users.
