Mutex and a shared condition variable are expensive compared to the single instruction.

But I had an impression that it is acquired before every atomic Python instruction and it looks that it is actually acquired for group of predefined number of instructions (100) that then are executed inside one GIL time frame [0].

Therefore it actually should not be a big obstacle to make Python code run fast by a JIT compiler.

This study does not show what you suggest. The problem is when you have several causes for the same effect some of all of them can fall below the noise floor. Being poor means slightly worse health care, worse food, increased risk of violence, etc etc. Trying to seperate each of them out in a statistically meaningful way is difficult and expencive.

Why does solar always need batteries? These are not "advances". India is adding 20k MW of solar and 10k MW of wind p.a. China is at 20+20. US at 20+20. Europe at 20+20.

30% of all new power capacity additions globally will be from renewables for the foreseeable future. Probably more.

This is without "batteries". Without subsidies.

The need for "baseload", "storage", or "the sun doesn't always shine and the wind doesn't always blow" are red herrings. They are not relevant.

Whether we like it or not, driven by massive cost and technology improvements, solar and wind are here in a massive way.
This is great but ... rudimentary. The same advice on 'create a 6-month emergency fund' no matter the financial situation, without regard to the cost of such a plan (in lost returns) and taking into consideration that depending on your financial situation, getting that amount in credit isn't that difficult.

Similar thing with life insurance. Sure, it is great for some. But when I entered that I am single and have no kids, it still recommends life insurance. Why exactly? It is known to be bad from an investment point of view - insurance should be bought for insurance reasons anyway.

Similar situation with renters insurance - without knowing what my belongings are worth, how can you recommend that I need renters insurance up to $500 per year?

p.s. the app doesn't work if you have ublock origin installed. Just an FYI.
You're both saying the same thing.

As for the good people vs. bad people argument, it should be noted that the good people have a harder job than the bad people. For the bad people to do their job, they only have to find one exploit, whereas the good people have to find most/all of them to have made the system secure. That's why employing people to work on security matters (whether through a bug bounty program or through direct employment), a company that values security shouldn't rely on unpaid volunteers alone.

This is really big news. Kudos to the Mesosphere team.
Do you happen to have another example of an city with a similar weather and employment profile that is significantly cheaper? Regardless of development?

Is there unanimous agreement that high rents(which are occurring throughout the US and abroad right now) are solely due to lack of development?
Totally agree, and I'm from Spain.

That whole national anthem (or pledge of allegiance) thing doesn't happen in most American schools, so many of us Americans can't imagine it either. With even northern states (including California) jumping into this, it doesn't seem like the country I grew up in.
Well, the supposed birth of Jesus. Guess you've got to choose something. Could go back to Ab Urbe Condita, I suppose. Or start a new calendar from 1776 or some other auspicious year. It's not like AD was used until like the 8th Century.
Here in Europe the big part of the market is in Java, then C# and then PHP. Even startups here are often using those languages (with some microframework like Spark for Java). The fact that also most universities teaches those helps

The Untold Story of Magic Leap, the World’s Most Secretive Startup
Similar dynamics in what way? Certainly there was no nominal wealth inequality in the USSR (there were of course people with wads of illegally obtained cash, and there were classes of people with access to a lot of things [which money couldn't legally buy] that the majority could not access, but officially wealth and income were very similar for everyone, in particular you couldn't legally own most sorts of assets traditionally held by investors, including real estate. So I wonder what sort of inequality correlated with life expectancy inequality in the USSR in the late 60s.)
How to present code in a slide deck
One exercise I picked up recently was to read the "Western" news, i.e. the Guardian and comparing with the Russian worldview at RT.com

RT might seem a bit.. over the top about certain topics (i.e. Syria and how Russia is doing), but is it really, or is it just OUR subtle propaganda that conditions me to take everything Russia says with a pinch of salt?

I can't parse this opinion. You're disagreeing, but I don't understand how. You also went on a tangent, avoiding my main point.

Are you aware that advancements made for space exploration have helped the medical field? Things like NASA's digital image processing of the moon helping with MRIs and CAT scans. Or LVAD leading to artificial heart pumps. NASA is basically able to claim at least partial credit for things like ear thermometers, automatic insulin pumps, implantable heart defibrillators, improvements in digital mammography technology, programmable pacemakers, LEDs, etc.

The discussion is about mining and I see no reason for why space mining colonies couldn't be self-sustainable. If they cannot be, then space mining isn't feasible or too costly. And if they are self sustainable, then the fossil fuel mined and burned on earth would be worth it. If this was meant for me to feel shame of being alive and consuming carbon, take note that this is reductionist thinking, the same reason for why we find ourselves in the current predicament. Carbon emissions are only important as long as we have an impending global warming phenomenon potentially pushing us over a dangerous threshold. And while that's certainly a potential catastrophe, it's reductionist thinking in the sense that carbon emission isn't the real problem, just a reaction in a long chain of reactions and focusing just on carbon emissions will spell our doom.

But going back to your first question, we'd have plenty of water if we wouldn't pollute it, I don't see the need for mining decreasing, quite the contrary, so instead of dynamiting mountains and filling the area with cyanide for extracting gold or whatever, I'd rather have all of this happen in space, instead of our backyard. Mining on earth is only cheap because the costs are subsidized, being implicit in the damage to the environment, a cost that we'll pay sooner or later. If we'd factor in the real cost, if space mining is possible, I don't think it will look that expensive.
Very cool. Thank you for the clarification. Is there a general name for these ROS kinect bots with the hardware and software combined? ROS is the general OS, right? Are there open source control systems on top of ROS or is ROS pretty much the control layer on a regular OS? I was under the impression that ROS is the framework bits to make the control software easier to write, but the control software is still diy (which is why I recommended robot researchers/enthusiasts). Expecting a smart robot off the shelf seems like a lot of people might set themselves up for disappointment.
But it is not cheaper than coal, which is what the headline says and was the impetus of my comment. I'm happy to see the costs going down, and maybe one day it will be competitively priced. But that day is not today.

Not British, but I guess the different national identities (English, Scottish, Welsh...) in the Kingdom play a major role, also considering the fact that one of them has had a fairly dominant role along its history.

Would a Scotsman or Northern Irishman identifies himself as such to a foreigner, rather than British ?

I’m familiar with the ‘Neill paper, and although my memory is hazy, I recall writing something along those lines in Scheme in college when we were learning about its own particular flavour of laziness (IIRC it involved lists where the head was a value and the tail was a thunk).

The thing is... I was aiming for the most literal translation of the human-readable instructions, which conveniently set things up to introduce the bug in using n eager version of `compact`, which segued into discussing the problem of mixing eager and lazy code in a language that uses the exact same interface for both.

The code I gave mimics what happens when a child is taught the method. They look at the list of numbers and count one TWO (cross off) one TWO (cross off)... one two THREE (cross off) one two THREE (cross off)... one two three four FIVE (cross off) one two three four FIVE (cross off) and so on.

It’s quite right and proper to advance from there to talk about how you can do multiplication in a faster way to derive FIVE, TEN, FIFTEEN, TWENTY and so on, and to line up the grid of numbers in such a way that you have faster access to an arbitrary number than traversing the list sequentially, and then you have the performance discussed.

But all of that would encumber the story I was telling.

As for the skipFirst, I added that when I decided to cite O’Neill’s paper, as it made for a literal translation of the introductory explanation she gives of the algorithm.

So now, I’m going to write a’proper' version in JavaScript, I look forward to your feedback.
The biggest chunk is the bandwidth charges from imgix. They do appear to be giving you a break on their published pricing, but not a huge one ($0.075/GB vs $0.08/GB). The CDN they are using appears to be Fastly, which also has a published price of $0.08/GB. So, there doesn't appear to be any overzealous markup on imgix's part.

At your scale, there are CDN providers that can get down to $0.05/GB or lower. That would cut your bill by $3500/month...roughly 20% lower than current. I assume moving your legacy CDN stuff at the same time might add to that savings.

Not sure how tightly bound imgix is to fastly, if fastly has some feature that's not available elsewhere, or if imgix would even be willing to entertain support for alternative CDNs.

Edit: Also curious if you've ever done any analysis to see if bots are using a significant portion of your bandwidth. High res images sounds like a popular target for leechy bots...maybe some savings to be had in detecting/blocking that?

No. && would cause the next command to begin once the previous had successfully completed. A successful install shoudn't start the next install attempt, hence ||.

On the other hand, OP and this comment miss the beauty of Randall's implementation, which is each operation is launched asynchronously ('&'), so it isn't the case that you try a few approaches one at a time, i's that you try all approaches at the same time.
The need for reliable energy or energy when the sun is not shining is critical important--according to the people of India. For example, according to this article in ClimateWire (a trade pub) http://www.eenews.net/climatewire/stories/1060026477/

Dharnai, a community of about 3,200 people in eastern India's Bihar state, had been without electricity for three decades. So when activists with Greenpeace set up a solar-powered microgrid in July of 2014, the excitement was palpable. But, residents said, the problems started almost immediately.

When the former chief minister of Bihar state visited to inaugurate the grid, villagers lined up to protest, chanting, "We want real electricity, not fake electricity!"

By "real," they meant power from the central grid, generated mostly using coal. By "fake," they meant solar.
Which is interesting as this is precisely what the Guild were hoping to prevent using a slippery slope argument i.e. Google might not be taking money from them but others scanning the whole work could.

Equally, the original agreement between the Guild and Google would have amounted to an effective monopoly but the Guild were fine with that as their authors were getting paid.

In this case, it seems that the courts walked a line between the 2 vested interests and produced an outcome that may well lead to a greater good in the long term.
It is, the article has it wrong, or rather imprecise.

I'm curious what new information was contained in this article that convinced you. I might have missed it, but other than the new promo video, it was the same information on the actual technology that we've already read on magic leap, packaged in a prettier article with a nicer story around it.
Every time Solar and Wind and other renewables get mentioned - people get very confused over what is 'baseload', 'intermittency', why those terms are important and the whole "oh but the sun doesn't always shine and the wind doesn't always blow argument.

The maths doesn't work like that. Weight is actually not a huge factor in cycling performance because you mostly go horizontally. Top athletes only go for super-light bikes because they need every tiny advantage they can get.

Adding a battery will increase the weight a bit, but the extra power from the battery more than makes up for it. Let's do some massively oversimplified maths:

A lithium ion battery might have an energy density of 0.5 MJ/kg. A typical insane Tour de France climb might be 2000m. To lift itself that high, the battery-motor system needs to only be (20009.81/500000) ~= 4% efficient!

The actual efficiency will be a lot* higher than that. Usually over 50%, so adding a battery is definitely worth it.

(I haven't mentioned the weight of the motor, which is usually more than the battery - at least on conventional e-bikes, but it still works out as being definitely worth adding.)

I think that was an attribution for the qoute, not credit for inventing solar.
You are correct in the sense that the power platform is not the absolute best in most case, but i think it's the best compromise : Titan/Xeon phi may have more FLOPS, but that's only for a restricted domain of application. For a general purpose chip i think power8/power9 still give a good value ( power consumption not withstanding).

I am curious as to how you guys evaluated the platform, care to ping me ?
True, though to someone completely outside this area, it doesn't seem to show any claimed benefits over hololens. To be clear, I absolutely don't think ML is anything like Theranos, but wonder what signals we, as third parties, should use during the stealth hype cycle.
I don't understand that law as well. So, you start being good, keep 'mostly' doing good and grow, and at one point, what has been good suddenly becomes bad just because you have grown more than anybody else?

IMR 18650s are very light, will fit in pretty any much tube on a bike, potentially even inside a tyre on a tubeless job, and will push 80A for 120 seconds, which is a crap-tonne of power.

Having a battery assist is the difference between working hard for an entire hill climb, or being able to do 30 seconds on 30 seconds off and fartlek your way up the hill - which is the difference between winning and losing.

For the mass of 10 cells (500g) you can get 25aH - which works out as about 60W for an hour at 2.5v - which is enough to save you 10% of your energy expenditure over a one hour race if you're going hell for leather - which is still the difference between winning and losing.
If people were fully rational, sure. But they're not. Record companies have been treating musicians like crap for at least a lifetime now, and there are still people dreaming of record contracts.

Whether or not Antarctica gets exploited (at the very least by some non-democratic countries) depends probably on commodity prices. And most of them are pretty low right now.

ROS isn't really an operating system but a framework to combine robotics-related code into one running system via a publisher/subscriber model. You'd typically run it on ubuntu as the actual OS

you actually can get an (90%) autonomous robot off the shelf, if you just want a differential-drive base with a lidar or kinect sensor. Most of the work is done for you in the ROS modules, it's just a matter of knowing which ones to use, installing them and getting them to communicate over the correct channels.
Agreed. Though I'm from Germany, a country that is historically anxious about national pride.

And that includes myself. I get why people want to feel proud of their country, but I don't need this. I view a state as a provider of infrastructure, social security, and societal stability. Therefore I'm not particularly attached to the concrete state I'm living in, as long as it provides these amenities to me.

Antarctia is protected because it's the one area of earth that hasn't been irrevocably fucked up by human activity - yet. It's quite likely that when the Antarctic treaty completely expires in '48 we'll see a free-for-all - just as we are right now with UNCLOS (which the US never signed) and deep sea mining - although that's all being kept so quiet and out of the public eye it's not funny.

Is solar viable for small installations without any subsidies ? I was recently looking at a 30KW proposal for a small enterprise in Tamil Nadu. The quoted price is Rs. 36 lakhs. At the rate of Rs 6.75 per unit, it doesn't even cover the interest costs. Does this match with your capex costs or is this way off ?

For Chromebooks that's a problem, but if I'm not mistaken, the "cloudbook" moniker is meant for Windows Laptops with Chromebook-like hardware(though the name may cover Chromebooks too, I'm not sure). In those cases, They're perfectly usable standalone, they just have anemic storage and give you A year or two trial to Microsoft, and maybe other, cloud services. But they're not tied to it as much as Chromebooks.
Yes, all solar installations are not cheaper than all coal installations.

But conversely, all coal is not cheaper than all solar!

That applies globally and in India.

The point is that solar costs are declining every year, by 10% p.a. In many sunny places it is already at parity or below (eg Arizona, Mexico, Rajasthan and Gujarat in India, Mexico). We have already seen several bids this year at US¢ 3/Kwh ($30/MWh). $20/MWh is in sight - that would be well under the cheapest coal.

This link is useful summary http://cleantechnica.com/2016/04/15/why-energy-experts-are-s...

(And none of this accounts for the massive unpriced carbon + health externality of coal plants).

Coal is staying at best flat + whatever the fuel cost.
