In 4D, we cannot use triangles directly (we could use their higher-dimensional counterparts if we want to classify 3-manifolds), so more complex formulations of curvature are required.

I am no expert in curvature myself, but I would wager that researchers would use Ricci curvature here.

There's also a nice connection to the Poincare conjecture. I was planning on tackling that in another article. See MathOverflow for an interesting discussion on this subject: https://mathoverflow.net/a/9717
It’s Biro in New Zealand too.

Just increasing the efficiency to 30pct is a pretty big deal. If these could be mass produced cheaply to market, that would be incredible.
> Weak orderings are defined as orders that can't distinguish between all members

I get that. This wasn't my question.

I want to know why I need to define operator== when reasonable behavior can be inferred from whether or not operator<=> returns strong_ordering::equal (or weak_ordering::equivalent -- the standards committee can decide if this is reasonable -- I don't really care). If I want special behavior, then sure, defining operator== might make sense, and then it should obviously take precedence.

But if the whole point of this new three way compare is to reduce the combinatorial explosion of things that you need to define, I don't understand the need to split the universe into {==, !=} and {<=>, <, <=, >, >=}, and never let them interact with each other.

The part I take issue with is the statement "The columns are strictly separate."

Maybe I've missed something, but I don't see why it needs to be like this. operator<=> seems to be a strict superset of operator==, because it returns information about when equality holds, (or when equivalence holds). Shouldn't that be sufficient? Also, what's going to break if you design a type where a.operator==(b) doesn't return true when a.operator<=>(b) returns strong_ordering::equal, or vice-versa?

Again, maybe I've missed something, but this seems like a mistake. They're removing all of the footguns except this last one. Why?

It's going to landfills for a reason. This has prompted people to investigate why and then write about it.
Yes, the max. energy from sunlight on earth hitting an envelope should be around 20-30 Watts (at 100% efficiency).

Also, the reported 29.1% efficiency have been reached at a temperature of 1,207 °C.
Do you have citations for that being the reason? And what about societies outside of Catholic influence? Seems odd to blame them.

And I never said they didn’t exist, so I’m not sure why you seem to have an aggressive tone. I know they’ve always existed. But with research showing intersex births becoming more common than ever, I have to wonder if there’s a connection to rates of being trans as well.

> If they are running this thing like a startup on MongoDB (seriously?)

Do you base this on recent info (latest versions w/ Jepsen tests)? If so, what specifically makes Mongo a "startup" db?
Easy, it would be like Xerox PARC and Lisp Machine REPLs from the 70's and mid-80's.

Which is something that one can come close to with PowerShell, Fish and any IDE based REPL.
That's not true. Emacs has several problems with big files. Though, to be more specifically, built-in minor-modes have them. So it depends on whether you run a bleak vanilla emacs without anything, or a mildly comfortable emacs with at least something like fontlock-mode and stuff.

But, 2000 lines are really not that much. Usually problems on my systems start to show at >10k lines.
There is a process for recruiting Debian devs where trustworthiness is a consideration.

https://wiki.debian.org/DebianDeveloper#Advocating_a_Debian_...

There is none for npm.
Can you go backwards and generate a project/boot.clj from a pom file?

And can lein read from your boot file?

Because npm and yarn tag the same input, produce nearly the same output, and can run tasks defined in the same location (the project.json). Does clj tooling do that as well?
There are no fumes in a modern incinerator.

Is that why people are against it? They think there are fumes?
I don't think this is right. In order to implement <=> for a class, you have to understand strong_ordering, weak_ordering, and partial_ordering in order to pick one, right?
>>Racket is good but the toolchain and libraries are far behind Clojure.

Plus they plan to deprecate the entire language's syntax in the near future.

Clojure is the way to go. It might not be perfect. But it works for most part.

That's the job definition and it's a crappy job. These companies are paying their employees poorly and try to guilt customers into picking up their slack.

I fear your analogy does not go far enough if you are comparing the JS ecosystem to the UNIX philosophy.

Javascript would offer a library for every single option, variant and logical operator for a UNIX command. Combinatorial explosion will devour the web. It already destroys dev laptops anyways when downloading something via NPM.
Clojure has 25000 libraries of its own so you shouldn't need to spend much time in Java-land.
Why not resolve the owner name to some kind of uuid at time of package require/install and saving it in the lockfile? That way, a package upgrade can detect if the owner name has changed and fetch the correct package.
> But they almost entirely won't, even when given software designed to let them do just that. I've never encountered any sort of form-builder or report-generator or whatever that was designed to work for clients "without needing a programmer" where clients didn't end up asking programmers to do all the form-building, report-designing, anyway.

Did you interface with the individual workers, or company as a whole? My experience is that usually, the software doesn't let workers do what they need, the workers end up working around it with Excel, and at some point information will trickle down through two departments and three layers of managers that some piece of software they're paying for needs adjustment.

> It's like they have jobs of their own to do or something. It's like division of labor makes sense and is inevitable in any non-tiny organisation.

Exactly. But their jobs are almost never correctly captured by software, so people get creative and invent their own workarounds. The unending popularity of Excel is a great example of this. Asking someone else to fix your software for you has large communications cost and time delay; asking programmers has also a large monetary cost.

4th result on "landfill leak groundwater" and first solid looking, non biased answer. Yes, modern, but that's a scope on an already scoped excuse.

Second, it's not limited d to landfills. Any corporation claiming they've handled things usually means "until we can disband our Corp structure and eliminate liability". See Superfund sites for other examples, or ask why my family's creek runs orange instead of clear.
My therapist also tries to explain the difference between a “depressing” thought and a “depressive” thought. The first is just sad: “my ex started dating my roommate and that makes me feel uncomfortable”. The latter snowballs into morbid or hyperbolic predictions of the future: “now I’m going to be ostracized from my social group because they won’t want me making things weird. I also work with him and my professional life is going to fall apart. Ill have no safe space and I’m going to crack & burn all bridges i have here. I’m going to need to restart my life somewhere across the country”
I don't believe I'm mistaken. From the first few sentences of the page I linked to, it says exactly what you said:

Wikipedia:

> Stated simply, decreased unemployment, (i.e., increased levels of employment) in an economy will correlate with higher rates of wage rises.[1] Phillips did not himself state there was any relationship between employment and inflation; this notion was a trivial deduction from his statistical findings.

You:

> whereas I wrote that low unemployment leads to higher wages

I made the "trivial deduction":

If low unemployment leads to higher wages, it means that the prices for the things those people are producing (with higher wages), are going up, or inflating. That, or profit margins for the company are decreasing, if prices are kept stable.
Programming is mostly the practice of reading code rather than writing, and this is where the complexity is felt.

It’s not directly relevant in a relatable way to most of us. If you can afford air conditioning, these conditions are survivable. Building empathy with faraway victims facing chronic problems is hard.

Honestly, it feels like the web is so bloated sometimes. Are the fundamentals really that difficult? We have raw CSS and at most we can have a layer above it that generates manage-able CSS (e.g. SASS). Why introduce all this un-needed complexity?

I’m guessing the effects would be secondary. If your business serves the unbanked, and receives its revenues in cash, it may be more convenient to pay suppliers with that cash than to deposit it and issue electronic payment. Not sure if that pushes any businesses over the edge, but it’s a factor.
I did some quick research on the POSIX thing and it looks like cd (without parameters) is defined in POSIX:

I really hope this can be done without the help and with the actual opposition from countries like the US, Hungary, Poland, and the other fascist or pseudo fascist countries opposing it. I highly doubt it though. I think what we need to start thinking about is how to live in a world with a +3° average temperature that can no longer be avoided. It's almost time to accept our fate and try to figure out the next steps because we are not going to prevent this catastrophe. Should be interesting times ahead. I don't think our children will be too happy or forgiving of our generation. Hopefully they don't put us oldies in concentration camps and exterminate us for what we did to them, but if they did, I couldn't blame them.
> Isn’t cash the only thing preventing banks from offsetting the negative interest rates to the general public?

No, literally every investment product, from government bonds to CDs, also plays that part. Cash is just the most significant counterweight to negative deposit rates.

(After taking into account fees, many depositors pay a negative rate to maintain banking privileges.)

This is the kind of things that makes me believe that part of the potential collapse will yield very good things. Bad diet, low activity .. all these are super detrimental and are double penalty both financially and existentially.

I essentially second everything that the person above is saying.

There are an endless number of press releases and public relations bullshit articles put out by people who have some new "breakthrough" in photovoltaics. Whether it's special weird cells, or flower shaped ground mount things, or whatever.

What I believe in, is what I can pull out my visa card and buy right now. And at the moment, here's what that looks like:

One pallet load (22 panels), of high quality 156mm monocrystalline silicon cells, assembled into a 1.99 x 0.99 meter sized panel. Rated at 370W STC (standard test conditions) per panel. Under $0.60/watt.

STC: https://www.altestore.com/blog/2016/04/how-do-i-read-specifi...

Everything else is either so high priced that you have to contact a sales person to buy it (weird fresnel lens concentrator and triple junction GaAs cells intended for use on spacecraft), or is not manufactured in sufficient quantity to gain even 1% of market share, and therefore is not stocked by major photovoltaic equipment dealers.
I've been using Clojure productively for years without ever having to import anything from Java.
Your broad point is right, but the SQ limit only applies to conventional PV cells, it's not a theoretical limit on PV efficiency and in fact has been exceeded by other cell architectures.
This is clearly not the intended target of the proposed law, and the law-writers (who are treasury department public servants, not politicians) are perfectly capable of ensuring the law is not written in such a way [1].

This seems like a case where politicians are damned either way. People complain incessantly (but justifiably) about there being too many loopholes that allow rich people to evade tax, and thus avoid contributing to government revenues to fund things like welfare. The ability to operate in cash, even for large transactions and transfers, is one of those methods.

So then they propose a law like this and get attacked on the presumption that it is an assault on poor people, when there is no evidence of this being the case.

[1] My partner works in such a role in an Australian government, so I've seen up close, the exhaustive effort that goes into ensuring law changes like this don't negatively impact vulnerable people.
You'd think that once VR got to such an advanced state, we'd have already long before synthesized effective medications / electrical-magnetic therapies (e.g. shock therapy or TMS) to effectively treat depression enough that the VR suicide simulation would be pointless.

OTOH, the most effective treatments we have for depression are almost a century old, have tons of awful side effects, and were discovered by accident (i.e. MAOIs and electroconvulsive therapy), so I'm not too optimistic in the pharmaceutical and psychiatric industries.

I know people who have said the primary reason they don't attempt suicide again is not that they feel life is improving or worth living, but because each attempt further reduced their QoL and they're terrified of what another unsuccessful attempt might yield.

The fact that any technology runs Dockerised or within K8 can’t be its principal selling point (above what the tech itself does) imo.

This ‘looks’ cool but I had to read a lot and still had to make some guesses about what it does.

How about a comparison of some real world use cases? For example, could I use this to store and query some structural information that might come from an hOcr or ALTO formatted ocr output? Can OCR even be plugged in? Can I intelligently index the diff of multiple versions of a file and query that?

I have no clear idea ‘cos the team behind it are so focussed in their literature on the technical detail.
People who exercise are different from those who can but don’t, just as those who smoke are different from those who could, but don’t. People who exercise almost certainly have higher energy levels to start with and are less likely to have lingering minor injuries, just as you’d expect smokers and former smokers to exhibit higher levels of addictive behaviour like high coffee or cola consumption than never smokers.

Epidemiology and nutrition have massive problems teasing out causation because people who X are different from people who don’t X in many more ways than in just that difference. The health benefits of wine over beer probably reflect socioeconomic differences in consumption for just one example.

The issue with a walking desk is that the treadmill only goes one speed, you have to manually adjust it, it doesn't just let you walk naturally. It just wound up being distracting. It's not like the experience of walking and thinking at all.

There are some reasonably stable packages in the npm ecosystem, it's just pretty much the Wild West out there. It really depends on what you're building. It's pretty hard to get a new SPA started these days without a development environment which uses npm, especially if you're running lean.

The problem is keeping your dependency tree reasonable. Even pulling in a couple of packages might lead to hundreds of dependencies. And even if you have the sense not to use an external package for something as simple as left-padding a string, someone somewhere in that dependency tree might not feel the same way. And that's all it takes to bring a chunk of the web down.

All of these problems of course are due to JS not having a mature ecosystem or standard library. People shouldn't need to reinvent the wheel every hour, nor should they be pulling in modules less than a dozen or two lines of code. That, and the constant misguided financial incentive to deploy ever more complex functionality over http are what lead to this aggressive push for cutting edge tools.
No, the article is about efficiently converting heat to electricity, it's not about solar panels.
Because it's alarmist nonsense that only gets published due to the ongoing hysteria. If higher temperatures than we're used to in Europe were catastrophic for human survival, Africa's population would be endangered by them and not be growing at the current rates.
Arkansas or Kentucky might have higher GDP per capita as separate countries because they wouldn't get brain-drained to the coasts as easily, and free of federal domination, they could make themselves a superior immigration destination.

With Kentucky, given the population, you can imagine New Zealand as a baseline.
The article kind of ended abruptly. The point about Encrypted Media Extensions and DMCA and rise of encrypted video playback within browser is an interesting point that needs more elaboration.

The story of how Internet grew and what made it valuable to users and what threatens it – it is worth articulating and illustrating and repeating each year as more and more people take Internet more seriously but don't know about these happenings under the covers.

Also, for the business model innovation to happen, existing business models need to be studied with care and deeper and broader understanding needs to prevail over more and more users.
Venus is the worst case, I never said this would happen at current CO2 levels but it could happen if they continue to elevate and chemical processes put out more CO2 while biochemical processes stop using up CO2 due to high heat. There is a true absolute runaway that could theoretically be achieved in an absolute worst case scenario.

Given that 1) you have zero problem grasping the concepts and understanding the examples, and 2) your difficulty is in solving the end-of-chapter problems; I think it is almost certain that your issue is one of making small mistakes that throw off your solutions (for example, didn't change a plus to a minus sign, left off a term, made an incorrect assumption, etc.). You just need to learn how to double-check your work and figure out where you went wrong. This is a skill that everyone doing nontrivial math has to learn. In a formal learning environment, you constantly get feedback on your mistakes through the grading process, which you obviously don't get when self-learning. My advice is to work the example problems before looking at the solution. After you have worked it yourself, you can then easily see where you went wrong. You should also get books of solved problems that let you practice this more extensively. There are problem books for pretty much every undergrad math topic as well as some grad-level ones. A lot of textbooks even have solution manuals that will show you how to solve the end-of-chapter problems in the textbook. An Amazon search with the word "solutions" and whatever math topic you want should turn up many examples. With practice, you learn how to detect errors and rectify them even when there is no solution manual.
Moreover, in any nontrivial application, you have modules and layers of abstractions - and those boundaries are DSLs on their own. It's actually good to think of them as languages the client code will use to write its solutions in (SICP makes this point early in the book too).

People are getting too hung up on the word "language", like it was something only the most experienced and smartest of programmers were allowed to build. Nope, programmers build new languages daily in their code; it's how you abstract things.
