Unless you live nearby nuclear plant and your electricity is dirt cheap - this is awful stupid solution.

On account that 1. we’re still far away from scalable and economically viable clean energy solutions 2. Natural gas is as clean as natural resources can be

I wish there were someone with balls and physics degree to ban this decision.
ITER has, explicitly, no intention of ever even addressing the important engineering questions. It has, e.g., no liquified salt blanket.
I have a rule that is simple, effective but also quite rude: if you can't deliver and maintain a 500 instances large infrastructure, same uptime and all, at half the cost of AWS by yourself (1 person) in 3 months using only open source solutions basically you should not have an opinion about this. You are just rationalizing your incompetence on this particular subject. Sorry to be this blunt but I am simply tired of listenting to people who can't do it explain that what I do every day can't or should not be done.
Well Zuck has said that Oculus Quest 2 sales are over 10 million devices, and the graph claims 2020 + 2021 is 12 million devices.

Considering then that the Quest 2 came out October 2020 it doesn’t seem like the graph can be far wrong. As the devices are very close to each other on the graph though it’s hard to say if the headline is correct.
I created brainpick.co.uk, where people who have given up hopes to resolve the issue, could sponsor a question, so people could work for money, instead of reputation.
Interesting—I find I have a hard time reading technical books on my ebook reader. When I read fiction, it’s usually a linear process, making the reader ideal: read, swipe, repeat until done.

With technical books, I often need to jump to another section, which is so much slower and more painful than with dead trees. Code formatting also tends to be abysmal on my reader—although books are not the best for this either. Maybe I’m not using my device to the fullest?
> So, AWS is hoping to exploit developers' willingness to do free work in exchange for nebulous "reputation" points

For me putting my SO profile in my resume really was a boon that allowed me to skip a lot of the technical interview (not all of it, of course).
A random dude showing up in a car at the border and just being waved through? Vast majority of the ussr population had not even seen a foreigner up close at that point, there was virtually no tourism and what there was, was focused on big cities. The Moscow Youth Featival, that opened the doors to more than a handful of foreigners, had been only 4 years prior. Given the extent to which KGB meticulously followed each and every foreigner setting foot inside the ussr and carefully catered their experience, there is no way this mission was going to succeed as described and no way the people giving this mission would know otherwise. This does not add up.
Also any that have too bright headlights. Crush directly into a cube. And then fine the owner if he doesn't move his cube.
Out of curiosity how far off grid do you go in your truck. That is, how far by distance and time are you away from the grid and stores? I know little about this stuff but am interested and would appreciate any helpful resources or videos you know of for a newbie. I’m interested from an overlanding / camping perspective but also a bug out vehicle perspective.
No, a bank can't go to prison, but its executives can. Further, a bank is a registered corporation and a legal holder assets which can be seized by courts. This means it can't escape legal action. The courts would seize the stolen money and return it to the rightful owner, while the bank would be fined and/or stripped of its license. The size of the bank is irrelevant, as far as the rule of law is concerned, because a key principle behind the rule of law is equality before the law. Therefore, no, nobody thinks that because a bank is small it's more likely to steal their money. That's a bizarre idea. The size of banks, and firms in general, is explained entirely by economies of scale. It has nothing to do with reputation, or the fear that they will steal your money. (No offence, but you sound like someone from a communist country who is unfamiliar with how the capitalist system work.) Lastly, deploying a contract is not the same thing as providing financial services. You can deploy a contract in conventional finance too without investing any capital at all. This is not what banks do. The problem with DeFi is that it's crippled because of its intrinsic limitations, namely the fact that smart contracts lack coercive power. As a result, most real-life contracts (such as a simple signature loan agreement) are unenforceable in DeFi, and therefore not possible at all.
It unblocked something which very shortly caused massive massive problems - as in 9 major crimes in less than 6 months type problems, where before she got so nervous she couldn’t even speed. she’s lucky she didn’t get deported or thrown in jail for years. If she was a man, she definitely would have.

It’s easy to say it’s all good - and time will tell. But yikes.
Sometimes the solution is to get a bunch of people who don't know it's impossible in a room and give them a deadline.

I'm not going to hold my breath, but it would be cool if it works here.
So its more about stand alone vs PC? The Quest display and tracking is pretty great.
source? this isnt true.
Nice goals! Similar to mine (higher weight but similar ambitions).

What routine are you doing?
There was also an FTC filing associated with the Quest 2 face interface recall that disclosed US sales numbers in the millions as well. 10M devices is a reasonable number.
I'm also interested in this, having tried and semi-successfully used mutual information for finding associations between multinomial variables. As an even more naive question, I find the actual selection of estimators bewildering. How do I know which estimator to use for mutual information? How do I know if my chosen estimator has converged or is doing a bad job on my data? Bringing it back to the topic at hand, does the estimator presented in the paper provide good estimates for a wider variety of cases than the mutual information plug-in estimator? If so I can see it might be nice for simplicity reasons alone. Can we have different estimators for this new correlation coefficient? Any ideas what that would look like?
Hmmm.. Maybe migratory bird approach?
Little late to this party but love the idea. One small piece of feedback: saying all PDFs are publicly available might scare people off. I'm assuming you're generating secure random links? I'd at least say it's only available to anyone with the link.
Over here air-water heat pumps have become quite popular for replacing old oil boilers, as you can keep using the existing water pipes and radiators. I don't think they're that common in new construction.

My father recently did exactly that, installing a unit by Mitsubishi. IIRC it has a COP of 2 at -15C, finally switching to resistive heating at -25C or so (which is somewhat unusual, maybe a few days or a week per year over here). He also has his old wood boiler as backup that he uses when it gets cold (it was a dual oil/wood boiler, though the oil burner and oil tank was ripped out as part of the retrofit).
did you guys know any updates about the static typing ruby? I wish it could be more like typescript
You can see some of the fitness ratings for VR games here: https://vrhealth.institute/vr-ratings. From personal experience, the boxing game Thrill of the Fight was a brutal workout - after ten minutes, I was sweating and panting. I saw the same from fairly fit individuals as well. Also big fan of Pistol Whip for fun lower body workouts (lots of squats while evading bullets).
What did Scientific American attempt to do?
I'm not talking about the USSR because I haven't lived there, but Eastern Europe. Yes, you are right, my description is simplistic but art was being amputated by the communist regimes. The Strugatsky novel was rejected on grounds of faul language and the Russian version was initially heavily edited. Of course it was published by the state, as all publishing houses were state owned before 1990.
Like content writing, content creation, reels making for biz, tiktoks etc.
This is a bet I would be absolutely thrilled to lose. But I'm pretty sure I won't.
I think it depends on the person and what they want out of a VR. I own both a Quest 2 and a Valve Index and I find I play the Quest 2 a lot more than I do the Index, simply because it is easier and more portable. The games don't look as nice, to be sure, but they're not terrible either.

(NOTE: I'm not saying I like the Quest 2 more than the Index. That isn't the case. The Index is an amazing system and the best VR experience I've had. I'm just saying I use the Quest 2 more often due to convenience, so, for me, it has its place.)

My Quest 2 has really grown on me and I'd buy a Quest 3 without any hesitation. Having said that, I only use the Quest 2 to play single-player games. I have no interest in online multiplayer games nor in VRChat. If those features are important to you, perhaps the Quest 2 isn't a good option.

I had no idea this was a specialised IC that played this tune!
I assumed it was a jellybean microcontroller, but thinking about it it makes a lot of sense. These must have been produced in the literal billions over the past few decades.

For what it's worth, I've come across at least three variants of this particular chip that play slightly different versions of the Jingle Bells/Santa Claus is Coming to Town/We Wish You a Merry Christmas tune.
In addition to the one in the video, there's one that holds a note for slightly too long during Jingle Bells ("oh what fun it is to ride" becomes "oh what fun it is - -", and another that repeats the first line of "We Wish You A Merry Christmas" a third time.

I wonder if they're knockoffs, and if so how they're constructed!
with what game engine did you develop the game ?
Thanks!
You use it to find the code and data of a paper - since it also lists other implementations - to run additional baselines on Imagenet in order to appease reviewer #3( who has no idea why your paper on convex optimization has nothing to do with this but it's easier to run them than argue with them).

Pre-parenthesis part is dead serious, parenthesis part is slightly hyperbolic due to accumulated trauma with bad reviewers
If there is a fire indoors that you cannot extinguish very, very quickly, you need to immediately get out and call the emergency services. The longer you wait, the larger the fire gets and the less professionals can do about it.

Don't try to be a hero and flood batteries from your 10 litres/minute faucet. Just get out before you inhale too much smoke, faint, and die.
I think this narrative is biased by your perspective as an enthusiast PC gamer (the PCMasterRace type of person). Oculus selling a console-like, works out of the box offering makes a lot of sense in pushing VR towards the mainstream. The existence of stuff like AirLink also points to strong demand from PC gamers as well. The only people complaining are the PCMR crowd who either dislike the focus on mainstream users (filthy casuals amirite?) or the fact that it's made by Facebook (somewhat valid, I suppose).

The market success of Quest 2 in comparison to Oculus PC-only headsets and the Index+WMR ecosystem makes it pretty clear which is the more appealing option to most people.
biggest recommendation would be dont do this as a short term goal with a diet.. that never helps and you will gain back your pounds. introduce exercise into your routine. eat healthy but dont deprive yourself of stuff. if you like to eat fried chicken eat it but try to make it yourself.

The OP has made some telling observations about all those working 25th December.

Living in India, I had worked in the US healthcare industry for over 15 years. I had to work every Indian holiday. Just imagine the list of festivals/holidays India has; they are perpetual, to say the least. I didn't have to work US holidays, during which I would be home while the rest of my family went about their business, as usual. I would say that it got to the point where I was estranged from my parents and other folks. Now, whenever I think about the sorry state of affairs which I felt had been thrust upon me, I'm filled with remorse for not visiting my parents more often. Every aspect of life has its pros and cons. I see a pattern.

Season's Greetings to all HNers!
Installing packages in system folders without sudo is just... not right.

Homebrew has been around for a long time. I've never seen a better alternative for macOS, do you think you could mention any of them?

Regarding MacPorts:

> MacPorts distributes source code that is compiled on install, so Macports is generally much slower to install packages. Macports installs packages under “/opt/local”. Macports uses root, which can lead to users goofing up their system or workplace policy issues

Sounds horrifying
Presumably: because electric rate charges vary with time of day, while cooking demands are relatively static.

In a high-renewables regime, there's the "duck curve" problem where renewable energy, especially solar power, is most abundant during the midday, whilst demand peaks in the early evening as lighting, heating or cooling loads (depending on season), and you guessed it, cooking loads come on-line.

If you arrive home at 17:30 and plan on eating within the half hour, you're using the most expensive electricity of the day.

That said, total cooking energy use isn't tremendously high (2--3 kW), and most heating tasks consume less than full output for well under an hour. You can operate a cooktop or oven at full heat for an hour for well under $1 unless rates are Texas-level high. That would be seriously atypical usage.

https://www.directenergy.com/learning-center/how-much-energy...

Taking advantage of lower midday rates would be possible with a crock-pot, slow-cooker, sous-vide, or similar methods, though that does require advanced planning and doesn't suit all cooking techniques.
Good suggestion, it was tough to narrow down the list! Here is a link to the ViT paper in case others are interested [1].

According to the latest ImageNet standings [2], ViT appears to have slipped to second place in Top-1 Accuracy. CoAtNet-7 is the new leader, but only by a slight margin and at the cost of what appears to be a significantly larger model.

Selective Separation Could Help Alleviate Critical Metals Shortage
I honestly (no flamewar intended) wonder if the people of China (the majority of its regular citizens) suddenly decided that they're actually not happy with where the country is going, could they successfully make a change in government? Or is the power grip (+ available technology) of the powers that be (Xi and co) already too strong as to make that impossible, i.e. beyond the point of no return?

I am asking because, putting China aside, other countries seem to be headed in a similar direction if are not outright copying what China's been doing during the last years.
Do you mean convection oven?
You're describing a VM with multiple languages. You might like the Racket programming language(s). It provides a powerful macro interface that can define new languages, and sandboxed execution to safely execute user code server side.

Makes sense. Why wouldn’t you want to understand the macro trends especially as it relates to a crippling pandemic?
“For impatient programmers” … 46 chapters.
Perfectly reasonable question. The answer is that it has been my experience (across multiple companies, over significant time) that they tend to think you're making excuses for not showing your real profile unless you have an actual profile to show them.
What's the difference between that and say, changing your brake rotors and brake pads? There's a level of danger there if it's not a professional doing it.

> It should be a depreciating asset, like a car or at most value-neutral.

The building unit depreciates, but the total value usually goes up due to the land value, not the construction value. Cars would also appreciate hypothetically if metals suddenly became more expensive.
The 800k is disputed as being far too low. Including for excess deaths that aren't directly attributed to Covid, the count is well over a million US deaths during the pandemic.
That's pretty awesome, VR needs better content, and if it was a chicken and egg scenario, this might be it. I haven't touched my Oculus headset in a few years because the content is so stale, but hopefully we start seeing more interesting games.
You're the one ignoring reality. In your defense, basically every clueless voter living in the US and a lot of Europe does it too, though.

In Tokyo, you can work part time as a non-union, non-salaried janitor or a nail stylist and make enough to live within 20 minutes of the bustling heart of downtown. That's due to light zoning restrictions making housing into a depreciating asset for everybody instead of a stupid fucking pyramid scheme

Which water heater did you get?

There's a reason 99% of people have non-stick aluminum cookware. Everything else is horrible, and I say that from bitter experience. How often do you scramble eggs on your cast iron skillet?

That said...

> can be acquired for under a hundred bucks.

You can certainly get a small set of non-stick aluminum cookware with induction plates built in for under $100, however, it's not the easiest thing to find in the first place.

MI is quite useful and widely used. It typically requires binning data though when distributions are unknown / empirically estimated. This approach is a rank-based score, more similar to Spearman correlation than Pearson. This allows for nonlinear relationships between the two variables.

A slightly critical review on the work van be seen here: https://academic.oup.com/biomet/advance-article/doi/10.1093/.... They argue that the older forms of rank correlation, namely D, R, and tau*, are superior. Nonetheless, it seems like a nice contribution to the stats literature, although I doubt the widespread use of correlation is going anywhere.
There was a period in the last decade when most high-end TVs had 3D functionality. It required extra glasses, but it just felt so cool.

I had a couple guests over a couple fun evenings, but just like other cool feeling pieces of tech - like my Xbox Kinect - the glasses are in a box somewhere.

This feels again exact like that: cool at first sight, but the novelty wears off quickly and I realize I don't want more imersion or more escapism. I just want better quality media on simple devices.
Specifically, as I recall from the Technology Connections video on space heaters, transmission losses mean that electric heating is less energy-efficient than burning the gas yourself, since most power comes from gas and coal. Solar doesn't work well in winter and at night (without energy storage anyway), and wind isn't reliable.

If you lived next to nuclear power though, electrical heating would beat gas. Between those two it's a mix. So these sorts of decisions should be based on whether your mains is cleaner than gas, factoring in transmission efficiency and seasonal production/load.
Mutual information is not trivial or even possible to estimate in many practical situations as far as i know. Example applications in robotics or computer vision, where mutual information would be useful are segmentation and denoising of unordered 3d point data, for example.
Lost to time apparently, there was a service called “PC Pursuit” that allowed you to dial into a local access number and then dial out again through a remote modem to BBSs in other area codes. The traffic in between was carried over an X.25 network. I used this service for a number of years before trading it for a Unix shell account w/ Usenet access. It was a little choppy sometimes but opened the door to a larger world.

I still use the phreaking files from that era today - the phone number I use has rung busy for at least forty years. You can still use those automated callback numbers as a convenient exit for long meetings “oops, I’ve got to take this…”
Years ago through HN I got introduced to Richard Buckland's course at UNSW on YouTube. It featured a microprocessor called the e-4917 which has always captivated me.

The reason is because I'm from a generation that learned programming in Java / Python and PHP. Which are higher languages that do not require knowledge about the way the "metal" works.

I've always been jealous of people who got to get their start in assembly, they seem to have a deeper understanding of the computer itself. Whereas I only barely understand the "higher" software parts of the computer.

So when I came across Buckland's videos's it was like this part of the computer was finally revealed to me. Seeing the CPU's interact with the memory taught me a valuable lesson:

That at the lowest level what is in a memory "cell" can be both an instructions to a program or the data used in a program.

I hope that with this post I can reach someone how used to be like me, and get them to a lower level.

PS: I also wrote a part two explaining how I programmed the emulator using React and TypeScript:

It seems to me that buybacks reward those who've held the stock so far but want to exit their position, and managers who want a bigger bonus short-term.

In contrast, dividends reward investors who want to remain invested, but I don't know what incentive management would have unless they too are shareholders.
It depends. Usually a paper doesn't have enough room to mention all of the possible choices in preprocessing, architecture, optimiser, etc. You can usually get pretty close with details just in the paper, but it's not always possible.

That's why a large number of journals now have requirements for publishing code and/or pretrained models (if applicable).

An annoying trend I've noticed in a number of SotA ML papers in video classification present multiple models and only publish the exact architecture & weights for the smaller models which are only as-good-as SotA (see tiny video networks, X3D for examples).
How many solar panels do I need to get 12kw in winter in the Pacific Northwest?

Answer: per this solar axis[0], we average 242Wh/m² in January. Assuming 25% solar panel efficiency, this gives 60.5W/m². To get 12kw would require 200m² of solar panels, or 45"x45". If we covered our entire house with solar panels it'd be 80m²=4.8kW.

And it chooses language that undermines or at least clashes with its point, e.g.,

> Red isn’t “more spectrum” than green or blue. Apples aren’t “more fruit” than oranges. That’s not how it works.

Red 'is' in fact 'more wavelength' than green or blue. That's exactly how it works.

The confusion the author bemoans comes from people actually knowing what characterizes a spectrum in general and taking that to apply when they hear the phrase 'autism spectrum'. The phrase itself is misleading.
I think sometimes a "black hole" is exactly what's needed for these requests. OK, sure, it's noted, and that's what we'll do if we somehow have nothing better to do.
