High birth rate is the main and only problem in India, like in many other countries in the world. Multiplication without control leads to a human disaster. Only birth limitations can be a solution.
When you compare it to median income it isn't as affordable as it seems. You can get a very nice house in Ohio for 200k but jobs there pay shite and decent jobs are really hard to get. Try paying that mortgage on barely above minimum wage. Keep in mind that energy, food, college tuition, health care, etc. are not that much cheaper than they are in say LA or SF.

Some cities like SF have it bad but much of the country has a housing problem.

Comma and semicolon typographical notation for partial resp. covariant derivatives. The comma is used to indicate a partial derivative: V^{\alpha}_{\comma\beta} = \partial_{\beta}V_{\alpha}. The semicolon V^{\alpha}_{\semicolon\beta} turns somewhat complicatedly (via Christoffel symbols) into \nabla{\beta}V^{\alpha}. There’s more detail at https://en.wikipedia.org/wiki/Covariant_derivative#Notation

These notations are reflected in “comma-goes-to-semicolon” which is discussed in MTW chapter 20 & 22 (esp. §22.4, Electrodynamics in Curved Spacetime) and other textbooks. Carroll’s online lecture notes at https://ned.ipac.caltech.edu/level5/March01/Carroll3/Carroll... discusses it briefly starting with the paragraph beginning “Our next task is to show how the remaining laws of physics…” and in particular (starting with) that paragraph’s penultimate sentence.

Even more briefly, we need generally covariant physics to escape the flat spacetime background into general curved spacetime and still get sensible electromagnetism and so on.

Even more briefly: the semicolon indicates a valid tensor equation, showing that we are fine when the basis vectors are not constant. Switching , to ; when it works hides away a bunch of work with Christoffel symbols, and what makes it work is the Equivalence Principle. Semicolon-goes-to-comma always works by gauge fixing, but unfortunately V^{a}_{,b} -> V^{a}_{;b} sometimes doesn’t; doing the full expansion by hand (well, or with modern automation) is one way to see if your physical theory is really generally covariant/background independent.

> superdense

Yes! As an example, and I haven’t really done more than scrub through it, and he really doesn’t go into any details beyond what you’d get in a standard textbook:

(note LOCAL equations only in this video and its predecessor https://www.youtube.com/watch?v=XqNVxFY-lCs)

Which leans heavily on

https://en.wikipedia.org/wiki/Einstein_notation

Putting the extra typographical dot on top of the , giving a ; can literally represent several pages of dense equations.

> jargon

Yes! A lot of writing that turns out to generally be really mechanical has been squashed out of General Relativity through the years. Unfortunately the notation itself — as typography — tends to “leak out”, so we talk about indices being in the basement or upstairs, Greek vs Roman, etc etc.
I feel like the situation at hand is very different. Crimea, unlike Hong Kong, isn't an alpha+ city that is one of the most important financial hubs in the world. While capturing Crimea by RF was extremely reprehensible, there was not much at stake there for any side not directly involved in the conflict. All there was in Crimea situation is just a geopolitical projection of power. With Hong Kong, the stakes are way higher, and I don't think that straight up capture of Hong Kong (Crimea-style) will go over nearly as well.

P.S. Also, not that it makes the situation any less reprehensible, keep in mind that heavy majority of Crimea population at the time of capture was ethnically Russian and was supportive of RF actions. Hong Kong residents, on the other hand, seem to be way less supportive of PRC.

> if you took the optic nerve and attached it to another part of the neocortex, that part would become the visual region.

FYI, that is super hand-wavey and covers over a lot about how the path of the information from the cones/rods gets into V1. The chain of neurons that pass infomation from your eyes to V1 is well studied [0]. Interruptions in that path cause a lot of sightedness issues and are not fun diseases to have. The musician, Stevie Wonder, among others, aledgedly has a form of blindness known as blindsight [1] where relfexes to motion are perserved, but information is not passed into the conscious mind.

In the end, though neuroscience is a facinating subject, we're just in the beginning of our understanding of the brain. More research is needed.

[0] https://en.wikipedia.org/wiki/Optic_chiasm a good place to start learning about the chain of information transfer.

[1] https://en.wikipedia.org/wiki/Blindsight

EDIT: Additionally, if you want to learn more about neuroscience, the best place to look is at Kandel's Principals of Neural Science [2]. It is a tome of a book, but is the best place to get a deep dive into the brain and our understanding of it. I've not yet seen anything else that is somewhat accessible to the general public but also gets into all the issues with any particular experiment. Most pop-sci book brush over a lot of the very important and thorny issues that each experiment has. I'd also love to know of a good book that is more accessible than Kandel.

Tech is most definitely optional: Nuclear energy was for a while considered a great option, but now a lot of people are (unfairly IMO) turning their back on it, and you see that there isn't as significant a number of new plants built (just to give an example)
Finally we are strong enough to write one of these who is hiring ads. Yes, we're hiring!

Who we are: The Modular Company, tech DD services for Venture Capital and Private Equity customers.

We're growing rapidly, we doubled year-on-year for the last three years, looking to do this again this year. Right now we have a mix of part and full-timers that form two teams and we are looking to build a third team in the next three months.

We are looking for an all-round tech person to help out with the Due Diligence work we do, preparation, interviews and report writing. Competitive salary, stock and bonus. If you are curious, want to know what makes things work and would like to join a team that consists of interesting people then please respond, we're color blind, age agnostic (our team spans 3 decades) and would be happy to hire women, men and in fact anybody else as long as they positively contribute to team and atmosphere.

Warning: this work is not for everybody. It is super intense, we deliver a 20-30 page report each week, it is fun and addictive but if you are unable to pace yourself then likely you are better off in a more regulated environment, we are not going to 'hold your hand' but give you all the freedom you need to succeed or mess up. English writing and speaking skills are almost as important as your tech background. We are 'radically transparent', that means that once every month we send out a very detailed report on how the business is doing to ensure that everybody is on the same page. This includes financials, a retrospective of the past month, looking forward to the month ahead and anything else that might be of interest.

Location: Near Amsterdam, Netherlands (Hilversum)
Remote is ok, but some office presence required, we work all over Europe. Some of us work from abroad (Poland) but this is while workable, not ideal so if you're in or near Amsterdam or Hilversum that would be better.

You may contact me through jacques@modularcompany.com if you're interested.

No recruiters or agencies please.
I think you're on to something that bothers me a little too. Games like Celeste are certainly playable as an ordinary gamer who doesn't want to practice and memorize precise inputs, but it's a popular game to speedrun because the collision detection in the game is complete trash. You can jump straight through some obstacles, get additional dashes, etc. that the developers didn't originally intend.

There's something un-fun to me that is hard to explain about all this. I don't like spending hours retrying a single challenge when I know there's a super precise series of inputs elite players or a TAS could use to get through in 5 seconds. I realize that's a very subjective thing and this is still fun to some players.

I've moved to playing mostly puzzle games like The Witness, puzzle platformers like Braid, and challenging "simple" platformers like VVVVVV. What I like about VVVVVV is that the inputs are incredibly easy to learn. You will die a lot, and there are people who can make it through the whole game in deathless mode, but I'm okay with that because it just means I need to get better at the game, not get better at memorizing a precise series of inputs and strategies.
Oh yes, and they played the long game until it was economically self destructive for me to continue. Never forget the time advantage a corporation has over an individual.

In the end I lost all my equity.
No, it isn't. XMPP was designed primarily as an IM protocol to replace proprietary messengers like AIM and ICQ, not as a service for group chats. It's a flawed protocol even for IM, and its conference features verge on broken. (For example: A user's visible presence in a conference is neither necessary nor sufficient for them to send and/or receive messages in the conference.)
Yea, I'm not sold on the productivity thing either, at least not on an individual contributor level when everything is going perfectly. But high turnover and/or low headcount in the senior engineering ranks can really send your team/company productivity right down the drain. And with a little investment in tooling and process, having a third of the team on video rather than in the room is a fairly modest inconvenience. And I'm sure better than half of slack messages at my company are between people sitting in the same room.
I'm not much in physics. Could someone explain what the picture actually shows ? I understand that there are 4 shots of an atom. I see that globally there are for spheres. But I don't understand the yellowish shapes...
I think part of it is funding--but part of it is also recognition. In a number of fields, the development of scientific software receives little recognition compared to the science--even if the impact is large in terms of the discoveries it enables. So, for say tenure or career advancement, it might be "nice" for you to do it, but nowhere near as important as publishing high impact papers (at least in many fields). Especially if a graduate student or postdoc commits too much time to it instead of research results, they risk not being able to continue in their field (though they probably have more options if they decide to leave science to become software developers).

Tesla is renowned for having lousy labor conditions. I'm not sure how much that filters up to upper management, but I could see it being a factor if you want more work/life balance at your job.
Probably more like a natural time to leave - Model 3 is past the initial hell and shipping more regularly, etc. And in this process have learned how to take a vehicle from end to end. So instead of working on a brand new car inside of Tesla, why not do the same thing on their own with a greater ownership stake?

Not always the best decision, but usually the kind of thought process one goes though.

You are correct. IRC is not airtight.

You do however get informed by the server after a netsplit has occurred... and key-up retains most of what you have said recently so achieving coherency isn't difficult, although a manual task.
I know plenty of people who would rather be destitute in BFE than live in the city (and it's not even a hypothetical question, a lot of these people are employed in trades where they could make decent $ in a city but there's no work for them where they live so they can barely afford a double wide). What's your point?

Interesting name: "Lucid"

This implies clarity. I personally think Tesla vehicles may fit the needs of a small percentage of the population (kind of like the new Mac Pro), but are overkill for everyone else, and the excitement in EV's is changing the world for future generations. This requires a car you can sell to everyone, not just those who would drop $80k on a car (or even $40k). I believe the core of what Tesla could be, a great EV, is obfuscated by things like AutoPilot. Interestingly enough, that's where most of the issues and headlines are as well.
They're fatal in the sense that you can't mitigate all the side-channels. It's intrinsic to HT/SMT that certain critical resources are shared without an ability to mask the side-channels. What you can do is make sure that only processes and threads with the same privilege (e.g. same UID) share a core. But AFAIK such mitigations haven't made their way into OS schedulers.

You're almost certainly right that HT isn't going away, the performance benefits are too great. But to fully minimize the security impact operating systems in particular, but also some userspace applications (e.g. browsers), will need to be aware of the problems. This is already the case more generally for cryptographic algorithms and similar software--e.g. how memcmp can leak passwords.
The reality behind solar power’s next star material
I live by the following hierarchy:

- Anything written down and transmitted digitally will be available to anyone who wants it eventually. Besides my copy, the recipient has a copy, as do any number of intermediaries. Encrypted or not, that encryption will almost certainly be broken in my lifetime.

- Anything written down on physical medium or stored digitally (but not transmitted) will be freely available to anyone that wants it eventually. It's slightly more secure than a digital copy, because I have physical control over the only copy and would most likely know if that physical control was compromised (so my NAS is considered transmitted since it is possibly accessible).

- Anything I say to someone in person is pretty safe, depending on how much I trust them not to record what is said (otherwise it becomes classified as digitally transmitted). Of course now a copy remains in their mind's eye, which is in some cases worse since it can be modified and they don't even know it.

- Any thought I have that I have never expressed outside my body is almost completely safe, baring successful administration of truth serum (or until someone invents adversarial brain scans).

How does this affect me in real life? I don't write down things I wouldn't want other people to know, and I am pretty careful about saying things I don't want other people to know. I use encryption whenever I can because it will at least slow down the attackers, but I never assume something that is encrypted is safe.
Well, by that metric it's about equally trivial for any maths student to solve indefinite integrals (e.g. using Wolfram Alpha), right?

It's not that I disagree about the utility of modern technology, but I just think that some things are inherently difficult for humans even if there is a handy oracle to compute them.
There's a lot an individual can do to minimize their own impact (but sadly, unless we get a significant percentage of the population to change, it isn't going to matter much). Here are a few off the top of my head:

- Give up meat. If you don't want to give up meat, chicken = far less greenhouse gasses than beef per measure of meat (Beef requires "around 28 times more land than the other options, 11 times more water and resulted in 5 times more greenhouse gas emissions" https://www.iflscience.com/environment/new-study-says-beef-1... ).

- Try and buy local

- Try and buy with minimal packaging, buying bulk can help a lot with this. 50lb bag of rice instead of 1lb, 10lb bag of beans instead of 1lb, etc.

- Find fun things to do locally instead of deciding you just HAVE to fly to Antarctica to see the penguins because your buddy Greg and his girlfriend did.

- Turn off lights when you aren't in a room, unplug stuff with phantom loads when you aren't using it, when appliances die replace with energy efficient models

- Make fewer trips to the store, don't order something on Amazon every day or multiple times a day as it is going to increase the chances you'll be getting multiple packages from multiple delivers and try and limit yourself to once a week or better - never.

- Instead of going to see the 376th Avengers film in the cavernous air conditioned theater with Dolby THX Rumble Bumble Ultra Eardrum-rupture Super Sound TM, watch it at home. ("figure out the energy costs, let's reference a 2011 Slate article that compares the energy costs of watching a DVD at home versus going to the theater.6 The technology at commercial cinemas eats up lots more energy than your puny flat screen. The precise amount can vary by projection bulb and by how brightly the cinema chooses to screen the film. Usually, it falls between 3.1 and 10.5 kilowatts. A typical machine projecting at a medium brightness for the running time of Green Lantern would consume about 9.6 kWh." https://business.directenergy.com/blog/2018/february/how-muc... then of course factor in driving all of those speakers, the air conditioning/heating for that cavernous room etc)

Yes, but a government and a corporation is much more than their head of state and corporate executive. If the actions of the government have a significant negative effect on a majority of the population, you can be quite sure that the government will be overturned at some point.
