(I've not fully read the paper properly yet by the way, but I work on 3d global image based localisation professionally for the last 4 years)

Compared to doing this for photos of buildings its simpler, as you know what direction the camera is pointing. This means instead of having to reconstruct a 3d point cloud, you can just keep a 2d image and have done with it. So at worst you'll need to keep an image of the entire area you want to position against on disk.

But, you shouldn't need to keep it all in ram. as you're not flying, you can make the assumption that you're never going to jump from one corner of the place to another. So you can have you current location and an area big enough to buffer against SSD access.

update

They have photographed the floor, and pre-computed a map by extracting SIFT descriptors, which from memory are 128*32bits. They throw most of these descriptors away and keep only ~50 per "image". To answer your question directly, an entire warehouse would probably be less than 1 gigabyte.
"Land" means different things to peasants or lords, just like capital does today.

Land for common folks was scarce -- and it meant that thing that can produce food for you -- the lord did not have any problems with food.

The lord did not want more land because he was hungry, but because it meant more wealth and people, making him more likely to be able to defend himself against other lords.

The same with capital today.
Capital might be plentiful for some people who are closer to the printing press, but not for others.
Depends on your definition of RDMA, too -- if you mean the Infiniband kind, it includes message passing, which is much faster for short messages.
I am trying to learn French through the usual apps, it seems to be going okay.

I am also trying to get into deeper reading where I spend a lot more time on reading literature deliberately with focus (I don't know if that is the right way to describe it).

I think there was a link submitted here a while ago which triggered it, and I realised I read in a very shallow but fast manner just to finish books. So I've been trying to read more consciously. Reading The Brothers Karamazov at the moment.
The new student also has the option of choosing a not worthless degree, greatly increasing their odds.
No, that scheme doesn't do what you think it does (and that scheme is occasionally done in the US, especially for luxury residences).

Suppose that the residences will be worth $1000 when built and it costs $500 to build them.

The pay-in-advance price will be around $1000 - interest.

The pay-in-advance price won't be significantly less than $1000-interest because the builder can borrow the $500, and sell for $1000 when built, repaying the bank and pocketing the rest.

The pay-in-advance price won't be significantly more than $1000-interest because if it is, folks who want to buy will wait and pay $1000 when the units are built (forcing the builder to borrow $500).

In other words, pay in advance doesn't result in below market prices.

If you add in some units which would sell for $500 but you're forcing the builder to sell them for $250, the question is "who gets them?" The answer to that question does not depend on when the payment is made.

In the US, the vast majority of the "below market" units will be split between friends of the local govt and the developer.

Yes, it would be nice if that wasn't true, but it is absurd to behave as if it isn't true (in the US).
I'm sorry if this sounds completely ridiculous to some people, but what do people use RDP/Windows server for in 2021? Given that ASP/Dotnet is portable to linux, what are people building that isn't better deployed to linux? It can't just be the legacy use-case, can it?
It's not. It's using WinForms with the DockPanel Suite library, with a VS2015 theme.
There is something self-defeating about large tech companies. I wonder if this is fixable or if it is something that we simply have to accept. I don't know of a single large tech company that managed to keep their engineering spirit alive over the longer term, eventually all of them (even HP!) lose their way and end up being run in short-term, short-sighted mode which more or less kills them, even though they can stick around for many years afterwards on momentum alone.
To be fair it mostly looks that way because ARM has ruled the market for at least a decade, and there's just so many of them. But yes, many vendors make no effort to mainline their code.

But some do, or pay those samaritans to, and as a result you can definitely get boards (including this kind of 5-port switches) that run completely supported on a mainline kernel.

My home gateway is a Turris Omnia, supported in mainline for years. I run a plain Debian on it, works great.
China court drops case against ex-Alibaba employee accused of sexual assault
None of the big power players or even medium power players have exactly stellar image. So does image even matter if you can get away with things anyway... Terrorism by state actor is default policy and nothing is being done about it... So why should China act any different?
Yes, that was my angle. And while I share your intuition to some extent, I maintain that it's difficult to get a scientifically sound conclusion without controlling for those variables.

Specifically, to refer to an average of $1,000,000 as a specific effect size, without controlling for the fact that many people with only a high school diploma would not earn more even if they had a college degree, seems suspect.
>Because unlike in a Ponzi scheme, the US government can simply choose to create more money,

It sure can, but this doesn't go far enough.

The US Govt' can only choose to "print money". It cannot choose otherwise. This is because fractional reserve banking allows financial institutions to lend out the same $1 multiple times.

The result of collecting $1 and lending 6 people that $1 with an expected total payment of $2 per debtor results in $1 causing $13 in the economy.

The obvious answer is you lower the standards that year because somewhere the system broke down. (It being much more likely that there is an issue with the system than some kind of statistical anomaly with the students)

Then you evaluate and attempt to improve techniques as is done every year.
> To start, I believe that the idea of "working memory" is largely valid. Think of it as the number of distinct ideas you can hold in your head at once, sort of like trying to hold a phone number in your head when you've just heard it for the first time.

Interestingly, testing myself with the Wechsler reverse-digit-span test, I found very large improvements in working memory from taking 20-minute afternoon naps and from modafinil. I'm not claiming everyone is alike, of course, but working memory is definitely not as fixed as height and eye color.

Specifically with regard to mental math, I find I can do a lot more when I'm lying in bed in a dark room than when I'm in an uncomfortable chair in a noisy cafe with people talking to me. Or, for that matter, classroom.

> Many of these students grew up in rich neighborhoods with good parents. They had most advantages you can imagine, seem reasonably intelligent when you talk to them, but Algebra will always be beyond them.

I tried marijuana once and found the opposite effect: when I was high, by the time I got to the end of saying a sentence, I couldn't remember how it had begun. But people report that I seemed like I was conversing normally; if they didn't know me, they wouldn't have realized anything was off. I wonder if these folks were experiencing something similar all their lives?
It's not. This is a regular .NET Windows Forms app and the docking/tabbing stuff is DockPanelSuite, I'd recognize it a mile away. This is confirmed by poking around in their .csproj.
> A narrative that (white) men are uniformly privileged and life is just easy for them.

This is very perspective dependent. I’m a black college student now and every conversation with friends back home includes some mention of dropping out because it’s not for us as well. When you see people with equivalent resumes already coasting by in the job market because they could get their last names and LinkedIn photos past the screening and into an interview it’s hard to believe that’ll change post-graduation. And most of us are already in planning on entrepreneurship because we know we’re not what companies are looking for even with fancy CS degrees. It’s like if I’ll have to sell sneakers to make ends meet after college anyways I might as well drop out and use that money bootstrapping this inventory SaaS. Innovation out of desperation, I guess.

It’s no way to live. But I think we’re approaching an inflection point.
>Intelligence is largely (~70-80% of variance) inherited

Also a scientist here....

Intelligence, however measured, is largely inherited. However, that inheritance is not genetic, but social.

It's now been rigorously demonstrated that common variation in genetics has very little to do with intelligence as generally conceived.

Just for some examples of well-powered studies:

>A genome-wide polygenic score constructed from the GWA results accounted for 1.6% of the variance of intelligence in the normal range in an unselected sample of 3414 individuals, which is comparable to the variance explained by GWA studies of intelligence with substantially larger sample sizes.

https://www.ncbi.nlm.nih.gov/pubmed/29731509

>in 2016, a second meta-analytic GWAS analysis with a sample size of 294,000 identified 74 significant loci. This analysis produced a GPS, EA2, that predicted 3% of the variance in years of education [a proxy for intelligence] on average in independent samples.

I personally prefer QtWebSockets.
I've used libwebsockets before, but I found the API error prone and crusty, and ended up eventually converting it to QWebSockets. That turned out to be a good move.
I wanted to try it out, but the code hasn't been updated since 2017 and the last F-Droid release was in 2016. Is this project still useful? Being updated to fix bugs?

I disagree with the premise of the article. It's attacking a straw man. Progressives believe that genetics matter. It's just that they believe other things matter more (such as fairness, equality, etc).

The problem is that these research studies tend to narrowly focus on trying to prove that white people are superior. Why? What is this the only question that interests such supposedly academic individuals? It's because, yes, they are Nazis. They can't figure out any questions worth asking that don't boil down to the same old race baiting.
AdNauseam: Fight back against advertising surveillance
I don't think the design goals of QUIC and this protocol overlap too much. QUIC achieves lower latency for connection establishment than TCP+TLS by merging the TCP and TLS handshakes and avoids additional handshakes by being able to multiplex multiple streams over a connection. But apart from that it behaves a lot like "multiple TCP streams". It isn't designed purely for short-payload RPCs - streams can carry gigabytes of data. It's also not tailored to the datacenter use-case, and actually might shine more outside of it. And obviously QUIC is encrypted by default, while this protocol doesn't seem to be.

That said QUIC is rather flexible since implementations can be done in userspace, and a lot of what this protocol is about can probably be done by running a custom QUIC library. The GRANT messages can be emulated with window size increments on streams, and the retransmissions just look like different ways of handling ACKs - so this might be emulateble by having some custom ACK behavior and an infinite congestion window on the sender (bandwidth is limited by the receiver using window size increments). The usage of hardware-supported priorities might be a bit more tricky to map into QUIC - but it might be doable too if stream data frames can be sent in different UDP datagrams using different priorities.

Whether that really works better than the default setup? I'm not convinced. The nice thing about standard TCP and QUIC is that it works with all kinds of traffic. Congestion controllers will allow coexistence with other traffic on the links ("oh, there was a 5Gbit/s log upload or software update download which used 50% of NIC capacity?"), and the congestion window adjusting itself over time will also mean that "small RPCs can be sent without waiting for any confirmation". It even means "medium RPCs can be sent at once, once we learned about the link capacity (congestion window)".
That's the gender-equality paradox, STEM version: the more gender-equal a society, the more the genders self-segregate occupationally.

It's important that this is not about any absolute value, but about the sign of the correlation. The "blank slate" hypothesis would predict that the correlation is positive, i.e. the more gender equal a society, the more equal the distribution.

The opposite is actually the case, the correlation is negative.

This strongly suggests that the statistical differences in occupational preferences have an innate cause. That difference is moderated by societal influence, not caused by it. When societal pressure are lessened or removed, the innate differences manifest more strongly.

And of course, it needs to be stressed that these are statistical differences, not categorical ones, just like the outcomes are statistical and not categorical.
> decided to model and refine things that almost no one notices anyway

You certainly noticed.
Businesses tend to prefer paying through the nose when it makes sense to for the executives to pay themselves and their allies. The absolute lowest number on cost is zero. China's governing organising principle over the last two U. S. presidents sounds rational if you compare the imagery of Jan 6's q-anon-man to 89's tankman.
As a non-native speaker, it took a while for me to notice that (a) the article is ironic and (b) he's using "offensive" as in "offending others", not the opposite of "defensive" ("attacking" others).

Ask your employer, most people don't know about it.
Show this article to anyone who thinks science isn't political over sensitive issues.
I find myself reading and thinking and quietly ranting about this (and similar) topics often. The reason being that fundamentally I feel we are witnessing an erosion of the acceptance of the scientific method itself.

The scientific method simply put is "Truth has more validity then beliefs". Of course we don't have access to Truth so we use evidence as a proxy to Truth via interpretation.

Obviously interpretations may vary and even contradict, but that's a good thing and discussion should be encouraged, not censored, as we hopefully stirve towards consensus.

In the spirit of this I have no problem with holocaust deniers moon landing truthers etc insofar as the presentation and discussion of evidence is concerned.

I think that there should be strong public unacceptance of any kind of scientific discussions being shot down.

> No, from a public policy perspective, the important question is what environment can we create that benefit as many people as possible.

The problem is that since there already is substantial variance in environment that different people experience today, but nevertheless the amount of variance explained by shared environment is very, very low, this means that if we want to increase intelligence using environmental interventions, you can’t designate some environment that some (eg. well off people) already experience, and get everyone into that environment, because it simply won’t work. If it did, it would already show in the amount of variance explained by environment.

Instead, what you need to do is to intervene by putting people in environments very few if any people today experience. This is the only approach that can work, as it can overcome the low amount of variance explained by environment. Suffice to say, nobody yet figured out what those unusual environments actually would be like, as you can’t simply copy whatever well off or genius people grow up like. If you do come up with something, it might end up being a hard sale too, given that this will be necessarily stranger than what people normally expect. But, if it works, you’ll improve the world massively and make history. Chances are against you though, as millions of people in the education industry worldwide have already tried almost anything you could come up with, and nothing really works.
How do you find time for work? I see your comments shitting on everything that's not Windows pretty much everywhere.
you shouldn't need a GPS fix, because you should know your position to a much better accuracy using the visual odometer.

for large scale 3d navigation, this approach is what we do, use a rough GPS location to cut down the search area. This was because we were using a stateless system. Its much more efficient to have a "rough localizer" to find that first fix, the optimise map loading based on current precise position and likely heading.

On this system smaller system, once you have found your initial position (which will at worse require you to go through the entire DB once) you can keep most things on disk and selectively load your active area (the maximum possible travel time + load time + fudge factor.)
If you actually look at the commits, it's mostly fixing the build and tweaking it to work on modern platforms. My personal opinion after trying it, I would not suggest use of Motif or CDE for anything besides nostalgia, it has some serious usability issues. But if you enjoy it, more power to you.
>In year 2021, I can tell you, not only genetics is taboo, culture is also taboo now. If an academic dares to say that culture matters in student outcomes (learning, discipline), the person can also get canceled.

An example of culture mattering is Britain, where you have three groups from the Indian subcontinent:

* Indian Hindus

* Indian Sikhs

* Indian and Pakistani Muslims

Sikhs and Hindus have been very successful; they are more likely than the average to be part of the British middle class (<http://www.theguardian.com/money/2010/dec/14/middle-britain-...>). Muslims are, by contrast, worse than average in every single social measure despite being, racially speaking, indistinguishable from the other two groups to any outsider (since none knows, or cares, about the myriad of caste differences); they are all "Asians" in Britain.
I hope this need for a citation comes from genuine curiosity and not some misguided ideological want to uphold the notion of equality in intelligence.

It just doesn't make sense given a more macroscopic view of things. If inheritance obviously controls the difference in intelligence between the human brain and the dog brain, or the cat brain, or the monkey brain, what black magic makes it so that among humans themselves inheritance controls very little of intelligence?

The 70% - 80% statistic seems like a ballpark estimate he pulled out of a anecdotal conclusion based off of a broad spectrum knowledge of the related scientific research. You likely aren't going to find a citation that proves this claim definitively. It does not mean that his point is incredulous nor does it mean that his point isn't part of common sense.

His point makes sense. It makes a lot of sense. The same sense as the fact that the covid vaccine protects against the virus even though for the longest time it was NEVER FDA approved (aka no strong citations). The conclusion was obvious despite not meeting the stringent verification of the FDA and many people were able to arrive at this conclusion without the science. Yet many people refused to believe the efficacy of the vaccine due to their political ideology.

I believe there's a similar biased attitude coming from the far left side of thinking. The unwillingness to see that the science and common sense points to an inescapable conclusion. There is no unseen magical force that makes all races, all genders and all peoples equal. There are differences, and the differences are biological and obvious.

Like literally genes control how ugly and how tall you are but not intelligence at all? By some crazy magic intelligence is the one thing that isn't at all influenced that much by genetics? Seriously, which viewpoint is more realistic here?

Seriously the same ultra left people who were calling out the anti-vacc people as stupid and unintelligent for refusing the vaccine are unable to see the exact same kind of ideological stupidity within themselves.

Any language built around one idea to the exclusion of others is necessarily a toy.

This is not to say that there is anything wrong with toys, as such. Toys can be educational, some very. Just don't confuse it with something that is, or may become, a generally useful tool.

This is why "pure object-oriented", "pure lambda calculus", "pure category theory", and "pure logic" languages flop. The world does not consult your language for what kind of problems it should present. The world, instead, presents all kinds of problems. Any big problem will turn out to be made of lots of smaller problems, of all different kinds generally unrelated to the sort the big problem seems like.

A useful language has what you need to address all kinds of problems. Useful languages are usually accused of being "impure" or "too complicated". They can't be summarized in a line, or a page. But there are reasons why those are the ones we use.
You are reading a lot on the 'conflicts' between China and the United States because China is potentially challenging US' dominance, and having competing interests in more areas than any would want.

You wouldn't read this thirty years ago, not when the Soviet Union still have its influence. When the US is trying to have China on its side. Shared and competiing interest is, and will always the core of any diplomatic relationship. China isn't any less commie or more worker-friendly back then, but that wasn't the focus of the conversation isn't it.

Vietnam isn't less commie than China is. India doesn't have better working conditions than China is. We aren't reading them because they are not as significant. Vietnam is simply too small, and India is still struggling to find its own way.
Kenyans, Ethiopians and (white) Americans are not genetically homogenous. Even two siblings can be quite different genetically.
