> I agree that there is no way to know which city it is in the first photo.

If you look closely, you can see stenciled markings on the yellow poles. These felt like official markings to me so I tried to figure out how to use the markings to narrow down the list of candidate cities.

According to Wikipedia, the _Burger_ newspaper is distributed only in three regions: Western, Eastern, and Northern Cape. There are not too many large-ish towns in these district.

So I made a list of all towns with >50k inhabitants. Looking at those cities on Street View one by one, I found there are only two towns where the yellow poles have the exact same typeface of stencil numbers on them: East London and Uitenhage.

So I took a closer look at either town. (After a few misses, you quickly get a feeling where to find the parts of towns where the roads actually have traffic lights). With a bit of luck, I actually managed to locate the first picture just by randomly clicking on corners. Its coordinates are 33.7648S/25.4012E.
Author here: I am happy to answer any question you may have about AlphaZero.jl. :-)
I was actually arguing that the Rust community should definitely look into formal methods, in particular TLA+ and Ada/Sparks.

The borrow-checher/free-of-data-races/fearless-concurrency taglines are only focused on memory bugs and unfortunately the community is still focused on memory bugs as well.

Thankfully, it didn't prevent the Tokio team that had to deal with concurrency bugs (beyond memory safety) to write a model checker for Rust code called Loom https://github.com/tokio-rs/loom.

Nethertheless this proves that Rust should grow beyond the fearless concurrency/borrow checker narrative because concurrency brings a lot of problems and memory/lifetimes are only part of the equation.
Why would you? Julia shines in this use case.
The problem in the US (as opposed to Germany) is that the barrier is not ability, but money. Wealthy families will easily place their kids on some of the greatest universities, while a poor kid needs to be a genius to go to a place like Princeton, or else will have to enter into loads of debt to have a decent education at a state university.
Yah, I should have deleted my comment rather than editing it.
NDAs seem to have a few valuable effects:

* You can smoke out people trying to brain!@#% you by saying use my NDA and making sure an officer of the company you are talking to signs it (lower-level employees may not be able to sign a binding agreement on behalf of the company).

* I've had many a partner call me and ask if they can share something from an NDA covered meeting with a third party. It's helped surface opportunities AND threats.

* I've had investors point out the NDA was a go-no-go check. No NDA, no further discussion.

So, there's value there, but it is subtle.

It's not clear that methane would be as workable; that's a large change from hydrogen to that. We at least know that hydrogen is workable, because an engine was built and tested.

As for the shielding, you can't use solely propellant as shielding because you still need shielding once the propellant is exhausted (the engine remains highly radioactive after having been used). And it's not clear that hydrogen provides suitable shielding for all the kinds of radioactivity generated here anyway; you might actually just need lead. Plus you still need substantial shielding in the event of break-up/crash on launch.
I've always assumed most writers for these papers don't actually come into the office anyway. What's different? They're extending that to full time staff as well?
I wonder how much our chances of surviving as a species change if we drastically increase the average lifespan of an individual. I think this might also be a solution for interstellar travel as well. If we're going to conquer the depths of space we need to take control of our biology first.

People regularly use Trazodone [1] as a trip killer. I personally haven't and I don't like using them, but it does its job pretty well from what I've heard.

What a complete load of nonsense. Do let us know what your AWS bills are like when you run your 100s of petaflops HPC job there. And what is the interconnect like? A few gigabit switches aren't the same as the interconnects on these supercomputers.
You do realize that there is gigantic nuclear reactor sitting about 93 million miles from where you are right now, right? An energy source so massive, it would only take a small fraction of it to heat and power several full planets. It would be like billions of nuclear explosions every second.

The Sun dwarfs anything we can do on Earth. Any arbitrary explosion of that sort wouldn't even register as noise next to the Sun. Our radio transmissions are directed and deliberate in a way that is noticeable even among the noise. Like watching scrambled HBO on an old cable box.
That's vastily oversimplifying things. XHTML2 was a markedly superior language to HTML in a few ways, but you still would have needed to have the same CSS & JS components to interact with an XHTML page.

This is the opposite of what I would suggest. Marijuana + acid is a classic recipe for intensity, and a way to re-enter a trip when you're coming down.

That smoking a psychoactive when you're on an intense psychoactive somehow helps you go to sleep makes you at extreme outlier fwiw.
There is a difference between noting an association between characteristics and acting on them.

"Racial profiling" isn't bad because it's based on the (correct, though specious -- they're poorer) observation that young black men commit more per-capita crimes, it's bad because it leads to law enforcement behavior that causes young black men to be stopped, frisked, detained, prosecuted and incarcerated at rates MUCH HIGHER than their per-capita crime statistics would indicate.

Basically: the idea that "black kids are criminals" leads police to disproportionately enforce the laws against black kids while letting "non-criminal" demographics off the hook.

But no one argues we should censor reports that detail youth crime statistics by race, which is what's happening here.
And the problem with that is - let me guess, they're fake news?
I sometimes miss putting on a CD and listening to the whole thing. Not every album is good for that, of course. And I can do that just as easily with any media player. Something about the physical media made me more likely to listen to the whole album, though.

I was a student in a Physics class in the mid-nineties that used connected HP calculators to periodically survey the class to get a quick handle on everybody's understanding of the material. I was a student in another class where the lectures were recorded, and once in a while if the professor was out of town, a TA would roll in a VCR cart, and we'd watch the lecture. It was interesting to watch new technology get adopted with very different approaches and outcomes.

Now we have K-12 classrooms using iClicker and there are open source solutions like https://github.com/qlicker/qlicker. This, to me, is one of the better potential uses of technology: helping educational professionals customize curriculum and pace.

We recently moved to a school district where there has been an investment in developing curriculum. It has been a learning experience for me as a parent to see how this can widen the subjects a student can cover, and the depth they can go into. It's not obvious, nor is it easily measurable, so I fear it is an easy target during budget discussions. Examples include units on it being ok to fail/take risks (I forget if this was 2nd or 3rd grade), using the bee bot (https://www.robot-advance.com/EN/actualite-beebot-educationa...) to teach teamwork and problem solving at a young age, and using Google Slides to create presentations about subjects like the weather.

As a parent of a 3rd grader and 6th grader, I see the differences between the educational approaches for the different ages, how people learn, etc. I'm in agreement with the author of the article that I'm looking forward to see how technology is integrated in such a way that it accelerates/improves education, without removing some of the intangible benefits of collaboration, etc.

The only place I've seen fast food cost more is in mountain towns -- taco bell was about .50 more.

I have no A/C, run solar power and my heater is extremely efficient. Diesel usually sticks to 2.50ish everywhere right now, but California does get up to 4.00. so that's an extra expense of about $80 a month?

The cost of goods is so low, it barely registers. Housing tends to be the problem.
There might be some of that, but there’s likely also “please be civil here regardless of what point of view.”
First of all this is very cool. Dunno if author is on here, but I’m curious why both Flux and Knet are used rather than just one of them (Flux seems the most Julianic?).

Also, is this really faster than PyTorch/TF? Last time I benchmarked Flux for non-trivial networks, the speed was quite good with small models but memory usage was ~5x higher than pytorch, and I couldn’t fit my models on the GPU for flux. For large models, I had to compromise on batch size in Julia, although maybe with Zygote.jl the memory issues have been resolved?
Yeah, but what if there was one that was aggressively priced due to using an ARM processor?

I'm really not sure how the market would respond to it. So long as it played in the Apple ecosystem, I think it's interesting for some things though.

From https://blogs.microsoft.com/ai/openai-azure-supercomputer/:

"""The supercomputer developed for OpenAI is a single system with more than 285,000 CPU cores, 10,000 GPUs and 400 gigabits per second of network connectivity for each GPU server. Compared with other machines listed on the TOP500 supercomputers in the world, it ranks in the top five, Microsoft says."""

Each of the big three cloud providers could, if they chose to, build a #1 Top500 computer using what they have available (that includes the CPUs, GPUs, and interconnect). That said, it's unclear why they would: the profit would be lower than if they sold the equivalent hardware, without the low-latency interconnect, to "regular" customers. The supercomputer business isn't obscenely profitable.
Haha, imagine who got my Loongson Laptop with OpenBSD for playing around?

My little cousin 9 y/o ...he knows how to update the system and packages, he plays with it very often and started to type some python programs i send him..often he tweaks them..like changing the color of the square. He has so much fun when he can 'magically' change whats drawn on the screen. Thank you all for that great system
The abstract says that the majority of the benefits of coffee probably comes from phenolic phytochemicals. This implies you can receive all of the same health benefits like lower risks type 2 diabetes by eating other vegetables.

"Propellant" - Thank you! I knew it wasn't technically fuel, but it's still being expelled (as you mention, if you don't expel mass with a different velocity relative to the rocket, then you won't be able to accelerate a rocket)
As blopeur said in another reply you need to feed data to the supercomputer, and as parallelizable as your algorithm may be some data might need to be shared between nodes at some point, just to name a couple of examples.

If you connect a lot of cloud instances to act as a giant distribute computing cluster they’ll receive/share/return data via network interfaces or yet worse the internet, this is really really slower than what super computers do.

For many applications that solution would be more efficient than a supercomputer, but for applications that need a supercomputer it would be inefficient. It just depends on what you need to do, but in any case it would be a computing cluster not a supercomputer.

(my two cents, I’m not into that field)
This seems to be the norm for many companies. Everyone is throwing in the towel on 2020 so far as the office goes with the goal to take a fresh look for 2021 at the end of this year. Many will likely never go back to the setup they had before.

If you’re in the market for commercial office space you can probably get some killer deals moving forward.
A couple of ideas:

1. There are strategic reasons for a country to maintain a strong agricultural sector in case of international instability, war... etc. In today's economy we can't be 100% independent, but we still need some level of independence we wouldn't get without government intervention.

2. Other countries are undercutting our prices for reasons we find unethical: extremely low wages, inhuman working conditions, literal slavery... etc. We can't control other countries directly on these fronts, but we can at least ensure that we do not contribute to those practices ourselves.

3. Other countries are driving prices down through government subsidies in a bid to gain control of the market, and our tariffs compensate for that.

I have no clue whether these reasons apply to sugar specifically, or whether the US policy on these questions is proportional and effective. But at least it illustrates that there are reasons why a policy like that makes sense for the country as a whole (and not just for sugar producers).
I just style XML directly with CSS. That works fine if you just want to display it in a browser. XSLT can of course do a lot more complex transformations on your data.
The nice thing with custom types is that you only need one type dispatching logic.

Sure, it works via stuffing the custom things in blobs, but then you have (1) an extra layer of indirection during dispatch, and (2) always waste a few bits or bytes to store the custom type information, even when you don't need it for actual blobs.

In principle, it's not a lot of effort to reserve a fraction of the type ID space for custom types. From a user's perspective, it's also much nicer to hear that a library cleanly uses existing extensions to the type system, rather than hijacking a general-purpose blob type.

If there's nothing that prevents it, feel free to take this as a feature request :-)

I wonder why in the current year™ this isn't considered racist too.

EDIT: I'm getting downvoted and I don't know why. When Trump issued travel ban on citizens of Iran, Iraq, Libya, Somalia, Sudan, Syria, and Yemen it was considered racist. I don't see how banning users from other countries using some other arbitrary measures is any less racist.

I appreciate your comment. I don't have much time at the moment to reply, but I'll say this:

First, I would encourage you to seek out this kind of feedback broadly and systematically (as you probably already are).

Second, perceptions change slowly.

Third, with regards to viewing established players with skepticism, savvy people follow the money. Can you break down the financials of Elsevier and its parent company, the RELX Group? How much of these profits come from closed-access journals versus some of the newer initiatives?

Fourth, though it is less common, some organizations do put effort into long-term initiatives that may cannibalize their cash cows. Let's talk about what history has to tell us about those companies and those transitions.
Normally I agree, but this is one of those situations where the problem goes far beyond "a few bad apples". The entire police culture in the United States is built on the "good" cops not reporting, fiercely defending, or even lying to provide cover for the bad ones. And at that point, every person who tolerates the bad behaviors ends up enabling them, and therefore become complicit in them.
IIUC, you're supposed to share the certificate proving it's a version of the waypoint nda, and the text is only on the website, so no one else can change it.
That is definitely an interesting perspective. It seems somewhat idealized, but if we accept the premise of the author, then sheepdogs that hurt lambs are not removed in US making sheep go 'Baa'.

Still, a worthwhile read.
I suppose it's a bit of 1 or 2 or 3. But there's also the issue that emergent properties which fall out of the overall design are quite hard to explain, and even advanced students of the subject don't fully grok yet.

For example, "code is data" is true in the most trivial sense for machine code, yet having code as structured data makes it much easier to manipulate. Having easy to manipulate code gives you the power to manipulate code at compile-time. Having code run at compile time inside the compiler, which is also an interpreter running the same language that you are compiling is kind of magical and mind-bending.

In fact, more recent research into this has gone down the rabbit hole even deeper, and it turns out you can have an entire tower of meta-levels (see for example http://www.phyast.pitt.edu/~micheles/scheme/scheme22.html). This is all continuing on the same basic ideas which were present in early Lisps, just crystallized and refined further and further.

Also, as research into macros has gone on over the years, hygienic macros were discovered, which Rust has adopted as well (and there are other languages which have them as an add-on, like Sweet.js). Deeply understanding how this stuff works gives you a better grip on the issues with macros in older languages (notably C).

And that's just macros (and homoiconicity). There's also lexical versus dynamic scoping. This is a lot less "magical" now than it was 10 years ago, when almost no mainstream language even had closures.
Meanwhile, my employer has said zero remote work once the state transitions into the next phase. They want to be "fair" to everyone, including those who have positions that cannot be performed remotely.

>The fuel to fill up a nuclear thermal rocket ... would be astronomical in cost.

Perhaps I have it wrong, but my basic understanding of a nuclear thermal rocket is that it uses a reactor to energize a reaction mass like water. The water should be cheap, and the nuclear fuel should be expensive, but how much of the nuclear fuel would be reusable? Would the total lifetime cost be less than a Falcon 9 assuming you replaced the reaction mass?

In a bit more detail, and perhaps with less snark:

UML has some decent diagrams. What they communicate, they communicate well. But don't diagram everything - that's a waste. When you need a diagram for something, a UML-ish diagram is fine. When you don't need it, don't draw it "just because". We're actually not in the business of producing UML diagrams.
