> Low Framerate Compensation so it's considered hacky and with a higher power draw

This is not hacky or has higher power draw - the display has a minimum refresh rate, and sudden large changes in refresh rate can lead to visible flickering.

The GPU and driver is required to handle this. The alternative is much more intelligent display controllers than is currently available anywhere, so the CRTC lives in the display and just receives framebuffer content whenever.

> Of course, higher refresh rates are better, but it's quite wasteful

It is negligible. Your GPU will do nothing most frames, and the panel power consumption comes from backlight.

> Moreover, not every mode is a multiple of that

Slow framerates do not need to be a multiple of high framerates, as the error becomes irrelevant.

VRR is the solution for fine-tuning for perfectionism.

This is a very odd line, it (to me) means that either Tribler could have a fatal bug, or the internet would have to go down.

Honestly I use Linux for the same reason people use Windows: out of familiarity. But progressively my experience is getting so bad that I am strongly considering Windows with WSL.

Example: My wifi drops occasionally. Enough to be super annoying. It used to work well, some update years ago skrewed it up.

Another example from today: Launching Steam bricks my system. No, I don't mean "Steam crashes". Not even "my DE crashes". My whole system freezes, and after hard reset it cannot load. Something something skrews config royally.

I am so tired of spending my weekends trying to find out what is wrong with my system now, instead of relaxing.

I don't like password managers in general mostly because the ones that do all the syncing up magic you want are closed source.

Recently I found out about Bitwarden and have been using it for a couple weeks. No regrets, it's great.

It uses E2EE to sync passwords between devices and the clients are all open source. It's also undergone multiple third party security audits.

Makes everything a billion times more convenient and I feel safe trusting it.

Which languages do you use most often? Languages are not created equal, some are clearly superior to others for a given task. If you can develop effectively in a better programming language, then why wouldn't you invest more effort in making the implementation of your task in that language more foolproof? Write better tests, clean-up the interfaces, you can even try to use formal methods to ensure correctness etc.

This whole post is above my head, reminiscent of reading extremely generic Haskell code. It looks super interesting and has been done very compactly. For someone who really gets the stuff it’s probably an amazing way to communicate the thing, but for the rest of us, the jargon just forms a barrier. That’s just how specialties work, so I’m not complaining or anything.

A question:

> The embedding preserves limits and exponents

What’s this mean? I’m especially curious about exponents because wildly different areas of math talk about exponents in ways that must be related but I don’t understand the connection.

Definitely agree that nature has us beat by a long shot, but within the realm of stuff people build, does what we're doing in medicine reach that level of complexity?

Apple traditionally advocated discoverable (without the documentation) features, particularly for cases where the user might be experiencing a problem.

If somehow you could dissociate the tech from the currency aspect, would you still qualify cryptocurrencies as "high-price trading cards"?

I wonder because where some people are attracted to crypto because of the monetary gain and then learn about the technology, others are turned off by the constant focus on the $ value and then don't learn about the technology.

I truly find it fascinating to imagine our future running on a crypto layer. I'm not talking about bitcoin specifically due to its inherent limitations (which may or may not be bypassed through second layer solutions).

But playing around with some of the DeFi stuff, seeing directed acyclic graph ledgers perform at 10k tps and seeing projects which truly can bring value to people really gets me hyped about these things working seamlessly together.

The internet is not worth a lot because of the protocols underneath it but because of what people have built on it over the years. These various cryptocurrencies interacting with each other more and more gives me the same impression.

Every boom/bust cycle crypto goes through brings in more creativity from people who are building on this new world and I have trouble finding fault with it.

Would love to hear some arguments on how this view of things could be biased or perhaps wrong.

Ask HN: Truly successful applications based on decentralized networks?
My definition here is something that has reached global scale.

The only things so far seem to target digital assets (cryptocurrency, music, movies, art etc.)

I think the primary issue always tends to be two fold:
- Decentralized network applications (e.g. bittorrent) tend to be started against an established oligopoly or monopoly and then face the wrath of the establishment eventually
- Massive scaling issues without the inclusion of some centralization

A perfect example of my second point is git. Git is the perfect example of a decentralized Merkel Tree based network solution. It grew and grew, but only really took off when the likes of Github gained a footing, using a centralized mechanism for discovery and sharing.

I feel that all decentralized applications will end up facing the same challenges. But the internet is huge, and DApps have grown substantially.

I am hoping to hear if there are any other massive or massive-potential decentralized apps out there?
The median wealth per adult in africa is $1600.

And the cost per adult would be over $24. At least a quarter of people in africa are under 18 I think, though I couldn’t find great stats. So the correct number would be more like $32. 2% of wealth per year.
Sounds like I'm about your age. I remember Venera being in the news and discussed at school in physics class (teacher was a bit of a "space" enthusiast).

Roughly in the same timeline, porch pirates have been rampant in my community (in the SF Bay Area nevertheless!) and causing a lot of headache for me and my neighbors (at least those in our chat group).

It seems to me that these CRIMINALS face little to no consequences here, both absolute and relative to the damage they are causing. The so-called police is willing and capable to do exactly nothing about it. Any confrontation either hurts the resident, or puts the (otherwise perfectly legal) resident under legal trouble... Which is weird, because this effectively means that the victim faces more risk than even the perpetrator, just by the virtue of having an address and living a proper, productive life!

In the end I can't help but feel they are the predator and we are the prey. And the rest of the society is, uh, pretty content with the status quo?

One of the whole purposes of conversion to pure fiat is to eliminate any reason to hold cash other than short-term liquidity in order to encourage investment in productive assets, driving production.

> It's just completely losing its value thanks to a long sustained QE.

Except...it's not, the quantity of direct, utility-producing goods and services you can get for a given number of dollars is declining much slower than the long-term average rate. Easy-money policies aren’t driving significant inflation, probably because we’d be seeing significant deflation without those policies given other conditions.

That isn't a problem unique to markets. Regulators frequently ignore foreseeable events like aquifer depletion and climate change until something sufficiently catastrophic happens to force them to take notice. Democrats in full control of the federal government for a month now, where's my carbon tax?

People also like to stomp on what the free market would actually have to do to prevent this. For a rare event, the cost of surviving it (i.e. winterizing everything) would have to be paid from revenues collected entirely during the event in order to give providers the incentive to do it. Otherwise the ones who don't would have an advantage at all other times. In other words, people might have to be paying tens of thousands of dollars this month for electricity to cover the cost.

And it's entirely possible that that isn't actually worth the expense. In that case what the market would do is raise the active price to something not that high, but high enough to curtail demand to what the grid could supply. So enough to cause some people to turn off their electric heat and drain their pipes and take a vacation to Cancun because it's cheaper than staying and paying that electric bill.

And then you don't get shutdowns, and that may actually be the most efficient solution, but people don't like it and put pressure on regulators to prevent prices from spiking that high. But there goes your price signal telling the market to winterize things.
Short sighted^^^
The electric grid in Texas is not meaningfully connected to the rest of the US to avoid federal regulation. The state has almost completely deregulated power generation in Texas. It's about as close to the mythical Free Market as can be imagined. Everything is driven by market forces, and the utilities responded by cutting costs.

High level & easy: chat bots. I have implemented a forth interpreter in several bots I wrote (admins only, for obvious reasons ;). Since they are running within the bot's code, you have as much access to the client's state as you allow/implement.
As to 1, it has already been established that there's no biological plausibility of backprob whatsoever. You can only call the current models "neural" networks in the vaguest sense of analogy. There is significant academic interest in this intersection between AI and neuroscience, to design biologically plausible neural networks (see e.g. spiking networks). I guess the reasons there not very well known in the larger ML community is simply that these approaches don't work that well (as of yet).

Personally I don't believe chasing perfect biological plausibility will be very fruitful (in short term). An algorithm that runs efficiently on wetware will probably not be very efficient on current hardware like gpu's. The reason deep learning is so successful is for a large part that they are very good at exploiting the efficient linear algebra devices we have at our disposal (transformers are only the latest evidence of this).

Greg Egan's Diaspora, Schild's Ladder, and Permutation City feel similar in scale if not exactly style. I've just started reading Alastair Reynolds's books, and those are closer to the sort of space opera of Banks, and so far so good. If you like really long books, Stephenson's Anathem is mind expanding and vaguely parallels some of Egan's books in terms of concepts explored. Finally I'll recommend A Fire Upon the Deep and its sequels by Vernor Vinge.

So no surprise Rust is faster.

edit nvm I thought dynamic linking slowed things down since static linking means code fits better in the cache. Looking at the points, it seems that either dyanmic linking makes code faster or people prefer slower dynamic code.

Probably profit. They want enrollments, so they create "safe spaces", which in turn are more breeding grounds for these types of individuals. It also doesn't help that fields like the social sciences are extremely heavily left leaning already, and continue to hire from their kind.
Exponents are probably the easier aspect to understand. For instance, what is the number of distinct functions between a set X and a set Y? Well, for every input value of X, we get to choose any single output value of Y. There are |Y| choices of output, so we have |Y| * |Y| * ... * |Y|, where there are |X| factors in that multiplication. In short, there are |Y| ^ |X| functions from X to Y. So we'll often denote the function space by Y^X itself, and thus it gets called an "exponential".

In the category Set, the "exponential" of two sets X and Y is exactly the set of functions from X to Y. In other categories with a concept of exponential, you get a similar internalization of collections of the category's morphisms as objects of the category. You also almost always have an exponential law, (Z^Y)^X = Z^(X*Y)). (If you interpret ^ as "if" and * as "and", you get a common law of logic that we often use when refactoring nested if-statements!)

For a functor to "preserve" an exponential operation (or any other operation) is to be able to do the exponentiation either before or after the functor without changing the result. In symbols, F(X^Y) = F(X)^F(Y). (Compare with linear transformations from linear algebra, in which f(a*x + y) = a*f(x) + f(y).)

Limits are a bit more fundamentally categorical, and I still don't have a good intuition for them. If you think of a functor as projecting the shadow of some index category onto your target category, a limit is in some sense a "best pre-approximation" in the target category, such that if you have a function from elsewhere in the target category into the part under your functor, you can equivalently make a pit stop at the limit object before continuing on into the functor's image.

In some sense, it's like an optimal border control point just outside your functor's image -- you can systematically divert traffic through the limit without actually changing the results.

I'm not sure how to intuitively interpret "preserves limits", since I guess you'd need another functor lying around whose limit is preserved under composition with your first functor. Something like F(Lim(G)) = Lim(F . G), perhaps. But now I'm just reading Wikipedia.
> Their whole world view is that "patterns of electrical signals in neurons" is where learning takes place

Actually, the mechanisms are chemical processes involving trophic factors (i.e. inputs to those processes) and alteration of the physical structures the signals are transmitted with. You say "the brain grows" but the alteration of its structure to strengthen our weaken transmission and connections in response to signals is how it grows usefully. Which was present in the work described by the article.
Thanks for the article; it took me back to memories of bootleg replacing the 40MHz oscillator for a 50MHz on my work’s IIsi over my boss’ objection. Now I have some idea of what was inside.

Looking forward to any future work you might do to similarly explain the modern PLL oscillators as well as the even more modern programmable MEMS oscillators.

> It doesn't really make sense to measure this in USD if one of the major hypothesis driving Bitcoin is that USD is being hyper inflated

“USD is being hyperinflated” is an easily falsiable (and obviously false) statement, so basing anything on it is nonsense.

(That it is imminently going to slide into hyperinflation is less easily falsified, which is why that is actually the perennial cry of cryptobugs, as it was for goldbugs—sometimes, the exact same people—before then.)
You mention it at the very end, but any idea why a more complex (and presumably expensive) oscillator is used?

Epidemics are a relatively new phenomenon as far as human evolution is concerned. Within a purely human set of hosts, germs don't feel evolutionary pressure to become more deadly. If anything, it's advantageous for a germ to be less deadly. The most successful viruses are the common cold viruses, not SARS or Ebola.

Epidemics only really became a thing once we started domesticating animals and therefore being around live animals for prolonged periods of time. This allowed germs originally adapted to these animals the opportunity to jump over to human hosts, for which they may be more dangerous than for the original host animal.

For more details on this point, I can recommend this video on why the native Americans were killed by diseases imported by the European conquerors, but the conquerors didn't bring any deadly diseases back to Europe: https://www.youtube.com/watch?v=JEYh5WACqEk
> Do they ever get resolved? Not in my experience. In fact I fully expect the same (non-)outcome in any replies to my comment.

Consider that it might be to the benefit of the reader to hear all the different possible ways of expressing the different arguments and counter-arguments, even when the participants themselves don't budge.

Also, I often find that while I don't usually change my opinion in the middle of an argument, it still helps me to have the weakest areas of my opinions highlighted so that I know not to invest too strongly in those aspects as time goes on. After reading a compelling counter-argument online and then seeing first-hand evidence of the strength of that counter-argument later on, I think I'm much more likely to change my opinion.

During an argument I think it actually benefits all participants to stick to a consistent viewpoint and defend it as strongly as possible to make sure that its strengths and weaknesses are fairly represented.
