> Sure, if you handwave the unsolved-at-scale technical problems with grid energy storage and make a series of generous assumptions about future technology

Grid storage technology is already there with pumped hydro storage(PHS). As 90% of built and newly building grid storage is already PHS. It is political problems and inertia that's holding it back. To be clear, I'm referring to off the river closed-loop PHS, which doesn't need a huge river check dam, flood zone, huge population relocation or ecological issues. All it needs is two places with area of 1sqkm each some hundred meter elevation apart. There is ANU study that claims we have enough of such sites for needed storage. Look at how fast China is building PHS recently. I think PHS approvals, even for closed-loop, in US are as hard to get as nuclear, which is holding it back.

Here's the thing about dark matter: basically everyone would rather have almost any answer other than undetectable WIMPs. They've tried. Very hard. And yet, here we are.

Here's the thing about science: reality doesn't actually owe us elegant or in any way aesthetic explanations of anything. We've gotten so many of them that we've started taking them for granted, started feeling entitled. But it's only a feeling.
At the end, it is all about popularity.

All these proposed changes focus on making Emacs popular, not modern.
Along with all the other good advice here, make sure to consider the idea of four types of documentation:

Documentation System, https://documentation.divio.com/

tutorials, how-to guides, technical reference and explanation

They each serve a different need during the phases of learning and using a system.
For some, the only thing stopping them from committing crimes is the threat of punishment. In a situation like that, that element no longer exists. I don't imagine it'll be many, though.
This type of distance is also measured in time units (including minutes) in Canada. Here's an overall Canadian measurement flowchart showing when they use imperial, when they use metric, when they use ambiguous volume-based Canadian cooking units that can either be metric or Canada-specific customary volumes, and when they use time:

True enough. Perhaps a standard or a reg could require no ads or tracking if a site accepts micro payments. Maybe the browser could enforce the reg or standard.
Kind of, yes. There are a few user creation details we need to polish so that you can follow the tutorial word for word without needing to do any click-ops on the console
In larger planes it's an easy range, yes. But it's not currently possible in any other commercial passenger plane this small.

I bet this is more like a rudimentary version of Eliza, and not related to GPT-anything. Ask how many pairs of panties she is wearing on her head, and it may pick up on the phrase "how many" but the rest of the answer is completely unrelated and quite similar to all the other responses. Real GPT models glom onto your subject and intent very quickly, producing really convincing responses.

More evidence it's just random, but maybe looks for the leading part of the question "Can you," etc. This is unedited, other than to add labels and spacing for HN markdown:

Input: Can you teach me math?
Response: I can't do it tonight but maybe tomorrow! :] xoxo <3 :) -_-;)

Re: Oh my god what are u doing up so early??

So I think this thing is just a fun project for someone grossly overstating what it's doing. It seems to keep track of some things (like teach/learn delayed opposite response), but not very well.
It's pretty well known that individuals _do_ need protections against this while institutional investors do not. When crypto gets on the news, regular, uninformed people go and dump their life savings in to it. No matter how much you tut tut and say they should have done their research, they will still do it. And preventing people from losing their life savings on scams is good for society in general.

Hard disagree on cheap pigment. Windsor and Newton Cotman Colors are "student quality", so they're more affordable because they have less pigment. As a result, your paint seems thin and light.

Use Daniel Smith tubes, or M. Graham tubes. Twelve small tubes might cost you ~$100-120, but they'll last for about a year if you paint every week. These brands give you *very* rich colors.

Learning to draw, paint, and mix colors is time consuming. It's best to get started with medium quality brushes and paper, and then move on to expensive brushes and paper after a year or two, by then you should be able to appreciate the relative difference between serviceable and high quality materials.

Thanks for posting the link so I didn't have to.
It would be very cool indeed. I can imagine myself gathering a bunch of old smartphones people inevitably throw away as it rots in a drawer somewhere for years and years. Then proceed to create a little network of these things and... I dunno, use as CCTVs or something. If we can get up to 50 sub-par smartphones we'll be able to make some sort of resemblance of a botnet!
Conservatives have complained bitterly that legalizing same-sex marriage disadvantaged people. You've got clerks who say it violates their rights. You've got people who say that it devalues their own straight marriages.
This may seem useless, but stop questioning yourself: make a choice, wrong or right, and stick with it. Making a choice, and learning to work around the consequences, is one of the most important character building events you will ever experience. Make a choice, resolve to stick through it no matter what.
Any options a company offers me, I'll value at $0. That doesn't preclude my working for them if they have an otherwise compelling offer.
> It's a sort of rationalist's advice in that it seeks to match a consensus bell curve. Much of it is good advice but there are lots of exceptions that ought to be tweaked through subjective practice.

My wife is an artist, and by the law of association, I have I many artist friends. I would say that starting out, the good advice that matches the bell curve is great for getting started. Learn the basics before you break the rules. That way you know you are breaking the rules and why.
Yeah, agreed, NATO gear is. Russia and Ukraine mostly aren't using guided shells right now.
Minority in the mathematical sense, not in the way most US based people think when they see the word minority.
Yes exactly. One of the really destabilizing things about them is that each individual event is pretty much deniable or dismissable, even to the person receiving it. They can only be noticed as a pattern over time, and even then it's subtle.

And since no one gets to experience life as anyone else, it's very hard to gauge whether you are having more negative experiences than other people. Maybe it's all in my head. Maybe this is normal, everyone is treated this way, I just need to grow a thicker skin, stop overreacting. Maybe I'm imagining it. Maybe I deserve to be treated this way.

The fact that it's such a subtle, barely perceptible pattern makes it worse. Hard enough to convince yourself it's happening sometimes, definitely not worth the effort of trying to get other people to see when they've decided not to.
I think the core problem is lack of a intermediate default path, besides rockstar or nobody. In some places being a high school teacher was a reasonable, and even quite prestigious intermediate path. Some researchers even did significant contributions to science while in such roles, like Hermann Grassmann. But today being a teacher is a ugly duckling between professions that require higher education, overworked and with worse pay nearly everywhere. In some places they even have to worry about shootouts at work.
Just watch the Linus Google talk. It's all there.

I have written Flink pipelines that solved similar problems to this post: sessionization of time-skew data points from multiple sources with variable and possibly large delays; simple and economical is not how I would describe it :) .

If one of your datasource get lag behind, Flink would buffer a huge amount of data waiting for it to catch up due to how watermark work when joining 2 streams, and you would still encounter out-of-memory error even with RocksDB from time to time if your session window get too large. In addition, with our state size frequently reached hundred of GBs, recovering from failure was not exactly fast either.
Even though the sanctions are imperfect, they still have a very real effect. At an absolute minimum, it vastly increases the overhead of the sanctioned country to sell it's oil, and those who do work around sanctions can demand and get a large discount, thus reducing revenues. Even more effective are the supply-side sanctions, and the Russian auto and air transportation industries are already seeing serious effects, which will only get worse.
Meta's memo: make FB more like TikTok, recommend posts from unconnected sources
You’re not the elitist, unfortunately you’re stating the truth and its academic hiring committees that are elitist.

Research backs up the idea that there is a small clique of “elite” universities that exclusively hire from each other. Also, the only direction of mobility is downwards, it’s rare to get hired at a more prestigious university than your postdoc institution.

No, it is around...a third where I live maybe? Or maybe a 4th of what rent would be like. But I can always sell/downsize and retire to somewhere with cheaper property taxes, which is something I couldn't do renting. Rents don't do that.

But watch the rent to home price ratio. There is definitely a point where renting just makes more sense, like when I was paying $1000/month on something that the landlord was trying to sell for a $1 million. Ya, buying in that case would be purely for speculation.

You ignored the part about how people are scammed using credit cards, cash, wires, etc. The problem isn't crypto - it's dishonest people developing scams to trick others into sending money. I'd bet that far more money is lost in scams using methods that don't depend on cryptocurrency rather than the ones that do. Just like with those other scams, education is a very important part of prevention.
I think the biggest missing piece is find a local art store. Local indie places are amazing, but even a chain like Dick Blick is great. Even a craft store can work, but make that your last option. The benefit is that the employees are usually artists as well and can answer questions. Its great to ask "is this $100 thing really better than this $15 dollar thing?"
You're changing the subject now. You were criticizing these for lack of maturity, not for being uneconomical. My point is that your criticism that they aren't mature is misplaced, since the component technologies are all well established. Of course, it could be LN2 or LAir storage doesn't compete.
No. If you invest your money in something you do not understand, you deserve to lose it. I'm sorry you think that you need some authority to put their thumb on the scale and tell you what you can and can't do with your own money.
Are <name_your_tech_here> the future of computing?
The fact the CEO goes on the defensive means he’s triggered by something which has a basis in reality. On the other hand I also get some of the points he makes. It’s my believe a lot of us are just decent normal people who don’t need the constant company employee wokeness and just want to build things, have a nice working environment (preferably at home) and then spend time on their hobbies and with their families. If there is injustice it’s good that it’s addressed but like many things sometimes the search for injustice and the need to make this about themselves is more a narcissistic trait rather than a genuine problem they want to solve.
Not first hand experience, but I was adjacent to a team that tried this approach. In short its playing on hard mode. Dev experience and tools, deployment chains, testing, etc are all possible but nowhere near your awesome userspace toolchains. Be prepared for lots of DIY action like building your own network or file io. The team also wasnt able to quite get down to the superfast ms start times and MB images that we were going for.

My memory is fuzzy but ISTR that the people behind seastar/osv moved on to an approach closer to what mrkurt is emphasizing with “container” composition plus firecracker for the environment.
Huh? Cryptocurrencies operate just as expected, basically the same as they did ten years ago. Crypto never changed, the users did.
Emirates have them going full steam ahead again (they have 120 of them). I hear the 9:00pm flying from my city to Dubai every night. Qantas have re-introduced them - I think four at least are back in service, three are undergoing cabin refits and by mid next year they will have 10 back in service (they are retiring 2 of the 12 they had).
Does any one on here have some real world experience with scylla?

We currently make heavy use of dynamo and are interested in something cheaper/faster. The marketing material is pretty compelling but I'm unsure of how hard scylla is to operate at scale.
They are building massive pumped hydro storage too. A lot of closed-loop PHS is being built by China. Closed loop PHS doesn't have same ecological issues as traditional dams, but is not as trendy as batteries and has almost same political issues as traditional dams in west. So, it is generally ignored.

Can you use EquityBee for early exercise?
It's Fox News. They're going to come up with something about any major change made during a Democrat administration. This is as predictable as the sun rising in the east.

It's not news in the sense of being unpredicted or remarkable, and it's off topic.
Absolutely, if you can do better elsewhere.

So this could start an exodus of their top talent, unless the company’s compensation is way above par.
I see. Yeah this is known as "debt peonage." It also exists in the Gulf States of the Middle East in the form of the Kafala System where they use imported servitude from the Subcontinent/South Asia. It's how the World Cup will be able to played in Quatar this year. See:

Here's the list of sites using Webassembly:

https://madewithwebassembly.com/

The use-cases are all very niche stuff... some examples:

> https://avocode.com/ much like Figma (which was written in C++) it's a heavy duty web app which involved a desktop-app like experience for working with graphical files

> Google Earth (obvious CPU-heavy non-traditional web stuff)

> various game engines and game-related stuff

> 1password uses it to "speed up their browser extension"

> PDFTron... PDF annotation app, so another Figma-like usecase

> some in-browser IDEs

So mostly it's just a) C++ type developers who don't want to learn JS for their hobby project b) it doesn't make sense for them to migrate their existing software to JS so they 'emulate' it c) it's some heavy-duty non-web-typical use-case.

I highly doubt it will ever serve a purpose beyond these niches. Which is fine... it's cool having the option but it's obviously not the first choice for any professional team targeting the web
But weirdly exactly the same actors.
Hacker spaces are the most relevant, when tech crashes are happening or tech hype is high: it’s important to have a community of people to simply hack with; to lean on each other in comradeship; to learn from; to teach. Hope comes from this.
Milk by definition does not have any added sugar. If by milk you mean various food products containing mostly water, emusifiers and sugar then yes they have little or no nutritional value. Stop buying “food products” and only buy real foods- butter, bread, meat, flour, vegetables, fish, rice, plain greek yogurt, beans etc and you won’t have to worry about added sugars.
No, my criticism of the lack of maturity of cryogenic air energy storage is still correct. The fact that it shares some components with air separation does not change the fact that cryogenic air storage is not mature technology.

Similar deal with ammonia energy storage. We've got plenty of experience with synthesizing ammonia for fertilizer production. We've got very little, if any, experience using synthesized ammonia as a form of energy storage.

It was you, not I, that started this tangent about air separation in this comment [1]. I was, from the beginning, talking about energy storage systems.

i certainly wouldn't want to be living in prewar houses with prewar safety and prewar appliances with prewar electricity efficiency and driving prewar cars and receiving prewar medical attention. but i guess to many people, that seems like an upgrade, because they are far too poor to afford modern living. life has gotten worse for a lot of people.

>I’ve also noticed that FAANGs sometimes outsource work that doesn’t scale as easily. The contracting companies are either in cheaper countries or they’ll accept a smaller profit margin. Or both.

Or they open subsidiaries in other countries. Google are developing Fit Bit in Romania and they are paying 10x smaller wages.
The complete list is

* F. Halzen, A. Martin, “Quarks and Leptons: An introductory course in modern particle physics” (Wiley 1984)

* D. Griffiths, “Introduction to elementary particles” (Wiley 1987)

* J.J. Sakurai, “Advanced quantum mechanics” (Addison Wesley 1967).

* P.E. Hodgson, et al., “Introductory nuclear physics” (Oxford 1997).

* H. Frauenfelder, E.M. Henley, “Sub-atomic Physics” (Prentice Hall 1992)

IIRC the Sakurai book is more about generic quantum mechanics, but he has two books, I'm not sure if this has more about particle physics. The other two are more modern, but I don't remember them. I also tried to keep the list short, because usually the main book of the course cover most of the topics.

Anyway, it's a mandatory undergraduate course for everyone that want to be a Physics. If you want to learn cutting edge particle physics, you should take one or two optative course about the topic, then make a one year undergraduate thesis, then take a 5 years PhD, and then perhaps 2 years of a postdocs. So the cutting edge is like 8 years away.
Lost in the discussion is the idea that the tank should not have a future, and neither should most weapons of war, because they are brutal inhumane killing machines from a past era that have no place in future societies - this is my view as a pacifist. My hope is that humans can move past the idea of war for settling conflict, otherwise what is the point of social norms like privacy, respect, and courtesy between people, when the same people in society can condone killing of their youth in war? In my view tanks are are a tool of war against the progress of society and I don't see that changing in the future.

Is there empirical evidence that giraffes with longer necks have a better chance of reproducing? A better chance of obtaining food? And, if so, what is the statistical benefit per extra centimeter of neck length?

That would be science.

But evolutionists rarely test these things.

Do you know what happens when you remove a peacocks feathers? He gets just as much peahen action as any other peacock. The peahens couldn’t care less. This entire idea of tail feathers (or necks) lengthening as it confers a slight reproductive advantage is nonsense.

The point is that cryptocurrencies are not secure nor dependable in the way that people actually need them to be, and they don’t solve any of the actual problems that people have with the banking and credit system.
I think debit cards are more variable with bank and perhaps jurisdiction - credit cards somewhat naturally come with such protection since as a user your agreement is with the issuer (and hand wave, hand wave, ability to authorise payments) not the vendor.
It's simple, and the same in all implementations: `Wait some amount of time to allow related events to arrive`.

For implementations 4, I suppose it's done by reading only data point with `insert_time < NOW() - some_delays`.

I think the requirement `Producers and consumers must have synchronized clocks (up to a certain resolution)` is simply so that there's no unnecessary lag between producers and consumers.
I can't do my job without risk of tick bites, and even if I did my dog would bring them inside anyways. I took three of them off of me on my car ride home today, though none were attached yet.

That said, I've had plenty of deer ticks attached to me over the years and have never had Lyme disease. I kind of get a kick out of hearing about people bringing ticks in to the doctor when they get bit to see if they should be worried. I'm pretty sure my insurance would find a way to kick me off if I did that.
