50 years ago, you'd have told us to avoid developing weather satellites because we already have proven cheap anemometers. Obviously, that would have been a poor idea in hindsight, nevermind the tangential benefits of other space tech (satphones, GPS, etc).

Who is to say that fusion plants are necessarily going to remain as expensive as you claim them to be in the midst of another industrial revolution? This isn't a Wikipedia article for no reason: https://en.wikipedia.org/wiki/Fourth_Industrial_Revolution

You have to do research if you want the benefits thereof. Sure it can be expensive and time consuming... but investments have cost and risk. We're trying to get a big payoff, not save every possible cent in the now.

Also, I would argue that the building of it (and design of it) is of course part of the research, not "something that happens before any research can happen" as you said.
The systems I worked on were mainly for user curated recommendations and not public rankings. Your rating is only small part of your recommendation. A large amount of your recommendation is finding other users with similar ratings on similar content to you. If 1/5 star system leads to less ratings from other users, then system's ability to find similar users/similar ratings become worse and can negatively impact your recommendations.

As long as there are no actual, native iOS, android and PC Apps built on top of IPFS or even an access GUI or interface with browser on those platforms, IPFS can stop dreaming of replacing HTTP.
Apart from mere 1-2% of world population who use internet, no one else is going to download a binary and run a CLI, and visit 127.0.0.1:8080/ipfs.
For majority of people chrome is a gateway to internet (for them Http is a prefix u put in-front of a url) unless ipfs goes to that level, http is as relevant as ever. I know software devs who don’t know they could access files from browser via file:// protocol.
In terms of the protocol IPNS, DNSLink and PubSub come to mind. You can publish things that change over time.

IPFS also does some deduplication against the data when you publish things.

In terms of the software, browser integration, which there isn't a whole lot around for BitTorrent AFAIK.

IIRC last time I tried Pop OS it seemed very usable and the only thing that stopped me from using it was some hardware issues on my rig (a faulty drive, not the fault of Pop OS).

I especially liked that they try to clean up keyboard shortcuts in a smart way.

(For reference my issues with Gnome 3 that they built (built?) on is the we-know-best attitude combined with what I perceive as agressive copying of certain Mac OS features and also not trusting its users.)
I don't understand what is so reprehensible about it. Consequently he isolated himself and went into spiral and then everything went to hell. It is quite possible that had he not he'd his drug of choice in room, things were different. It is exactly the same thing if parents support soccer club and then the kid ends up spiraling with troublemakers. In retrospect the soccer was a mistake for this kid.

Just because we like computers and they did good to us does not mean having 100% access to one for him was right decision. In fact, it did caused massive issues.

The kid who leaves his room for socialization only is an issue. The kid who spends too much of his time playing video games is an issue. Some amount of playing is fine. Some amount of being alone is perfectly fine. The "out of room only for food and never going outside" is not fine.

If there is anything that harms young men, it that the above is normalized instead of being seen as sign the kid is loosing ability to cope with both real life and computer. And then, when they are alone, depressed or bursting angry, everything and everyone is blamed. Parents should be even more understanding, the girls should have go out of their way to meet guys in their rooms, the teachers are horrible for not tolerating them mistreating other kids and so on and so forth.

Except that saying that having kids socialization primary online, purely in gaming and hacking communities is a bad idea, because those can be quite atrocious.

I really don't know why you'd assume people wouldn't tbh. Yes, I am (approximately, at least) a non-user of facebook and if I were being polled about it I would answer a question about my views on its effects on society.

Ask HN: How to Calculate?
a friend and I were talking about holiday plans and realized we have no idea how to go about solving this:

All other things being equal, which would be 'better'/'safer' statically(?) - 6 hours on a bus with 50 people or 2 hours on a plane with 200 ?

(forgive the covid reference - its just how it came up. Only interested in how one goes about calculating things like this..)

P.S.
Is there a name for this sort of problem/math? Something I could google for more info?

Edit:
Hmm - another way of saying this might be - whats gives you the best chance of having your lottery ticket drawn - 2 drawings from a pool of 50, or 6 drawings from a pool of 200?

Thanks!
I for one love transient web services.
This is not anymore about developing "nuclear vs fossil" but about developing "renewable sources or/xor nuclear".
Why do people insist on referring to web apps with generic stock data as an alternative to the terminal? Even ignoring the fact that this is focused only on equities, the terminal is built around power users. it needs to be like vim. Super fast and you can access everything without leaving the keyboard.
I think the application of it is reasonable only when you are thinking of simple applications like Yes/No notifier and not outputting logs. I wonder if it works well with TQDM so I can see the code execution progress bar.
The rebase feature of https://git-fork.com/ is actually pretty nice. Interactive rebase works well, the only shortcoming is its lack of support for `git rebase -r`.
> Multithreaded performance, on some benchmarks, scales almost linearly with each new thread in the best case—e.g., when using 20 threads, an 18.1× speedup on one benchmark and a 19.8× speedup on another.

Interesting. When I write Python, and I write Python most of the time, I'm not chasing performance. But when it comes to speed, a 18x speedup gets Python up to par with currently much faster languages like Java. At least if you are willing to spam threads like your life depends on it.
> To put it bluntly, if you have enough to power baseload, you have nothing, except maybe pitchforks in your face.

I don't know what you are saying here.

> WRT baseload demand, I don't see how it's relevant to pretty much anything.

The concept is relevant as renewables cannot currently provide baseload power demand without infrastructure that hasn't been built yet, ie. storage and interconnects.

> Baseload power - I don't see how one would use it as a backup, unless you're throwing energy away, or it's variable, hence not baseload.

Throughout this thread, you have continued to ignore that I have explained baseload power demand and baseload power generators are not the same concept.

Baseload power generators, as the Wiki article mentioned, traditionally provided baseload power demand, but there's no reason why baseload power demand needs to be met by baseload generators. Variable generators can provide baseload power demand:

Historically, most or all of baseload demand was met with baseload power plants, whereas new capacity based around renewables often employs flexible generation instead.[1]

"Baseload" is not shorthand for "baseload generator", but rather used to describe the minimum demand you need to meet without the lights going out.

I'm using my phone right now. The annoying "accept our cookies" popup you mentioned took up 80% of my screen and 100% of the space reserved for text I actually cared about. There were also a ton of social media sharing buttons which I never use, taking up space and reducing privacy.

I didn't get a reader mode prompt for some reason, so I used the outline site which got rid of all that. Apparently that site is serving ads now so I won't be using it anymore.

It's wrong about bank money creation as well.

Banks don't just create money because they like your smile. They issue their own liabilities at a discount against collateral, the charge over which they take as their own asset.

The collateral has to exist now, and generally not in the future. And it is this that causes the problem with banking - they are renown for wanting to lend you an umbrella when the sun is shining.

Banks are for the most part liquidity providers against existing assets. And it is the existence of existing assets and the market for their liquidation that generates the systemic risk limit on bank lending expansion.
You are correct. This article, written in 2021, does not apply with the motivation stated in the article anymore, outside of niche applications. FP is actually faster in many situations nowadays (for example divisions). If you account for the extra shifts you need for fixed point operations, then FP is certainly faster.

Ignoring the reduced range, you can perfectly store integers in FP variables. Even banks could store everything in FP instead of integer variables in the lowest unit they support (for example cents). Integers at overflow fail catastrophically, so that also has to be controlled for. It is not the case that the loss of precision for large FP values is fundamentally worse, though it does happen earlier for the same total size of variable.

Integers and fixed point save space if you need a large range. The exponent of a fixed point is stored in the code, instead of in the variable. Integer instructions are encoded into shorter binary form, because they were part of the introduced set from the beginning (if you disregard the extra shifts required for fixed point). These are the advantages as far as I can tell.
Looking back at your post I definitely see better where you were coming from and I do think I was in error to respond to you, you're right. I was frustrated at a few different posts in this thread and maybe conflated some of what you were saying with what others were saying.

I think you are probably right about the poll as well; there's a more specific statement on leger's own release about the poll[1] about methodology and it does seem as if they just pulled people at random from their panel and does not mention weighting them. Which is surprising to me.

I think the problem is this is already on the edge of what is technically possible.

To provide power to the US it would presumably be easier to take advantage of US deserts and lay cables over land rather than cross-Atlantic. This avoids security and engineering problems as well as reducing transmission loss.

Also batteries mitigate the timing delay problem. Also these are not exclusive projects can do both if there is demand.
> is an OLAP database a common go-to for longer-timescale analytics (as in [1])?

I would not consider Clickhouse or CrateDB "classic" OLAP DBs. I can speak for CrateDB (I work there), that it definitely would be able to handle 600GB and query across it in an ad-hoc manner.

We have users ingesting Terabytes of events per day and run aggregations across 100 Terabyte.
I know the theory; the practice is different though: plenty of places doing just fine on solar, wind, and battery.

Wind still blows at night though. And if you install a bit more than you need, you can deal with temporarily reduced local capacity as well. And with the cost savings, 2x or 3x is entirely feasible (but probably overkill). And if you use interconnected grids like this article talks about, it's always going to be windy somewhere and you can add remote solar setups, hydro, batteries, etc. to the mix. Batteries alone remove most of the need for expensive gas peaker plants in a lot of places already. Interconnecting a diversity of solutions provides plenty of base load and resilience. Texas could have uses some when their baseload providing gas, coal, and nuclear failed them last winter.

The issue I have with "base load" is that it's a very fuzzy term that seems to be rarely specified in GW. As soon as you do that or specify the amount of time you need to bridge with that capacity, the relevant unit becomes GWH. Which of course is a common unit of storage and energy production. Plenty of ways to provide large quantities of that sustainably; and people already do in many ways. It's just a function of cost and engineering proper solutions. It's not even that expensive mostly. Especially compared to building nuclear power plants.

Yeah, fair enough, I can see it being hard for most people to bin Nestle (though not Sinclair?).

My response to Nestle was a "me personally" thing which probably doesn't apply to most other people - I don't really buy branded junk food, almost everything I eat I prepare myself from fresh ingredients. I read through the Wikipedia list [1] and didn't see any brands I've purchased this year.

But you're quite right that I was wrongly exaggerating by saying it was easy to boycott Nestle. I should have just emphasized that it's possible to boycott Nestle (if you know what the subsidiaries are), and easy (I think?) to boycott Sinclair.

One thing I find difficult to reconcile is China’s apparent success in adopting capitalist, free market principles set against manifestos like this, which talk about building a great “socialist state”. Is that label meaningless intentionally? Is it a sincerely held (but misguided) belief? Is it simply a preview of how China plans to ultimately take (forceful) public ownership of the fruits of private industry and innovation? Or is all of this planning and adoption of market economies just a means to birth a socialist end state into existence?

I also found the following portion chilling, as it has all the undertones of propaganda and the worst of the Cultural Revolution, except it’s all being admitted in the open:

> Fifth, we must promote common prosperity in the spiritual [and moral] lives of the people. The promotion of common prosperity is highly integrated with the promotion of all-round human development. We must strengthen the guidance of the Socialist Core Values, and education on patriotism, collectivism and socialism. We must develop [our] public culture enterprise, improve the public culture service system, and continuously meet the diverse, multi-levelled, and multi-faceted spiritual, moral and cultural needs of the people.

> We must strengthen public opinion guidance on driving common prosperity to provide a favourable public opinion environment. In doing so, we should clarify various fuzzy understandings, and guard against impatience and fear of difficulties.
Oh yeah, and I'm running the Pro Display XDR through a USB-C 3.1 Gen 2 (10Gbps) cable. Plugging that into the VirtualLink port on an Nvidia RTX 20xx card is the easiest way to get the native 6K @ 60hz with 10bpc on Windows. These days you can get these cables at lengths up to 3 meters, which is nice. There's also this weird VR headset cable which works a treat if you need something longer or have a graphics card without the VirtualLink port: https://www.aliexpress.com/item/4001290509128.html

Well you have to understand that my mental picture from your past description is FreeBSD running in KVM on NixOS running on managed GCP/AWS, which is a somewhat confusing and convoluted architecture to me and I'm not sure what it's for or what the possibilities are that can't be done with some other setup. You could probably simplify and cut out some of those pieces. But if you meant something else, then let me know.

AFAIK you actually should not be using mkdir, because it is racy to have more than one process writing to the toplevel hierarchy. It's only safe to do that from the cgroup manager. That's what I've seen with all the existing implementations anyway.

"Systemd puts user processes in a part of the cgroups tree where they can't work freely, by default. You have to use a systemd unit or the dbus api to break out of that box. That is a design decision on system's part."

It's a design decision that was made because of cgroupsv2. You should really read systemd's documentation on this if you haven't, it describes in detail why this is. https://systemd.io/CGROUP_DELEGATION/

Edit: and also the kernel documentation on delegation. https://www.kernel.org/doc/html/latest/admin-guide/cgroup-v2...

In particular, any other container manager that wants delegation needs to do this same thing using a similar mechanism that you initiate by configuring it somehow. (It doesn't have to be a unit file or dbus call obviously.) Processes cannot just freely break out of their cgroup, that wouldn't be secure. Sorry if you know all this already, maybe a reader doesn't. Or maybe this is helpful to you if you want to add this to startup, I don't know.

"If I was putting user processes in cgroups, I would give them space to work amongst themselves. "

Ok now you lost me again... is this not exactly the purpose of cgroup delegation?

You've posted an awful lot of messages, but the only one remotely related to crypto's intrinsic value was the following post which makes no relevant point at all.

https://news.ycombinator.com/item?id=28902307

In it, your main thesis is that you allege that crypto offers a way to "completely shield value", which is outright and patently false.

Even so, trying to portray crypto in general and BTC in particular as serving as a store of value is an absurd notion from the start, as it's renowned for being highly volatile and so prone to crashes that halve it's value that crypto's hardline proponents already invented the concept of periodic corrections.

On the other hand I still cannot configure CMD-tab to work like on Windows and most Linux desktop environments ln my brand new Mac.

Keyboard navigation (moving between or selecting words or lines of text) still seems somewhat hit or miss even though it is better than when I left Mac OS behind in 2012.

Of course this might not matter to you (and I even know some of you prefer the separation between "application switching" and "window switching") but for many of us these are way larger issues than having to fix a config file once.
> Sorry, you are conflating my arguments. Being cheap doesn’t solve the availability problem, I never claimed that.

I mean, you kinda did. Quote: "Renewable energy is cheap, so it doesn’t matter if you can’t store it efficiently."

Yes, it does. It does matter that you can't store it efficiently.

> With nuclear you still have a problem of demand above baseline, so you need infrastructure to deal with that.

With renewables you already have the problem with the baseline. I love how you just dismiss this as not being a problem.

> Renewables have the same problem except sometimes the baseline it self drops.

Exactly. In addition to having the problem of demand above baseline, they also have a problem that their baseline is zero.

> The answer is the same you build infrastructure that can handle such drops.

You can't solve a baseline of zero with more infrastructure. What you're basically saying is "every country has to have enough renewables to always be able to cover any amount of demand for any of their neighbours for any length of time." This simply doesn't work, and is not scalable in any shape or form.

Additionally, renewable energy is unbelievably inefficient in comparison, and it's extremely hard to "just" build more infrastructure for it.

The largest offshore windfarm that provides 1.2TW of energy covers an area of 630 square kilometers in the North Sea. That's less than Frances smallest operational nuclear reactor (1.8 TW).

And all of those 630 kilometers? Their baseline is exactly zero (if there's no wind). That nuclear reactor? Its baseline is effectively 1.8 TW 24/7.
Agreed. I open nearly every HN article from an unknown domain in incognito/private mode. At least half implement this kind of dark pattern.

I find it spectacularly baffling for this kind of content-marketing website, where income presumably does not come from advertising, nor trading in visitor data, but from their DBaaS. Why would such a company risk alienating their visitors like this? It makes me question the decision-making in their unrelated, primary service; their conscientiousness; even their security. Truly mystifying.

Think about the datascience use case: you need to load data from disk or network as fast as possible and compute a lot of CPU-bound operations right after that.

Threads will allow you to split your I/O in multiple procedures, so you might start computations as soon as possible when the data is ready. They will also allow you to massively speed up aggregates without having to create a new process each time (which doesn't allow you to share memory). Threads are a BIG issue when you don't want to rely on asyncio[1].

Note [1]: Asyncio pools are single-threaded because of the GIL. This is already bad enough in practice, but they also perform very badly in CPU-bound contexts. This make them an absolute no-go when dealing with datascience code: a cpu-bounded core in an i/o-bounded wrapper.
I don't think it's hard on purpose. Not sure what those files are but they're in all likelihood copyrighted and therefore illegal to distribute. So the emulator developers make it the user's problem. It's just like the PlayStation emulators and their BIOS images.
