Also not an expert on the topic but here are some examples of space-ready cameras with pictures and specs:

Obviously radiation, extreme temperatures, vibration, and vacuum are at least some of the problems. They explicitly state that lens have no moving parts, I’m not sure why that is an issue and how can they focus without moving parts - maybe they’re just permanently focused on infinity and hence close objects are blurrier?
Lens distortion might be just normal with uncorrected very wide angle lens which you want to make framing/steering easier. Otherwise you might need a separate camera just to help you aim the first one.
> But – and here is the great sleight of hand – the Bank has seen fit not to include house prices in its measures of inflation. So, throughout the 90s and 00s, they could then “prove” inflation was low or moderate and interest rates meandered lower.
Aren't rents included in the CPI? I would be surprised if they weren't since it's a pretty huge part of most people's monthly expenses.
Then it would either mean that the rents rose along with the house prices (in which case this effect is included in the inflation figures) or that the actual housing costs didn't increase -- it's just less profitable to buy and more to rent.
You are correct, per according to Consumer Price Indices: a brief guide by the Office for National Statistics (directly indexed pdf, so google the name to find), here are some selected examples of UK CPI factors and their weights.
Class: Weight
Food: 93
Alcoholic beverages: 20
Clothing: 59
Actual rentals for housing: 62
Electricity, gas and other fuels: 48
Purchase of vehicles: 38
Other recreational items, gardens and pets: 32
Education: 21
Restaurants and cafes: 88
These weights feel intuitively off to me, but I imagine costs like rent and education look low because only a subset of the population is paying for them, even if they are huge cost to members that cohort.
A lot of old-school financial advice seems to focus on the importance of saving and avoidance of debt. It seems reasonable but I always wonder how applicable that is in the modern times with our record-low interest rates. Short look at the tables in [1] suggests that, for example, you could gen 5% after-tax real returns on government bonds in the 19 century. Today, that would be unthinkable.
On the contrary, near-zero interest rates recommend more debt and more risky investments, because (a) debt is cheap, and (b) inflation (stagflation perhaps) will nibble away your savings if you try to ignore the equity markets.
Docker storage engines remember all the layers by storing incremental differences so it makes little sense to have a layer that only removes things (like the last RUN in https://github.com/iron-io/dockers/blob/master/ruby/Dockerfi...). You can see with `docker history <image>` that this layer has 0 bytes and you can access anything that it removes by using the parent image (`docker run -it 88ae7e32865f ls /var/cache/apk`).
Heh, looks like the author fixed this [1] and it now uses the technique you suggest, based on issue #22 [2] which restates the same thing as your comment, basically chaining everything together with `&&` in a single `RUN` entry.
> IPv6 has massively increased the number of available IPs, allowing every sensor and relay within a system to be addressable from the public internet
That's a really scary idea from the security point of view and something that bothers me about the IoT craze. Every consumer device visible on the Internet should quickly and reliably self-update its software if a security issue is found and remote updates are still a bit tricky to implement in embedded devices (little storage, diverse hardware).
Even if updates were easily implemented, you still have the same problems as consumer routers: once the product is off the shelves, there's little incentive for the vendor to spend money on support to even offer updates.
Number of hours worked per week is not everything. I suspect that Americans do work less over the whole lifetime -- the retirement age has decreased (at least for men, see [1]) while life expectancy is increasing. The problem is that it's impossible to estimate total hours worked over lifetime for people presently in their 20s-30s and current pensioners give you a delayed statistic.
Personally I think that economy based on a 15-hour work week would be sub-optimal. Total salaries being equal, I'd rather employ a single person working 40 hours than three working 15 where you need to deal with lots of communication and administrative overhead.
Maybe the solution would be taking multiple "gap years" during your career or "mini retirements" but many employers don't like holes in your CVs.
Yes, but you presume that single worker working 40h/w will charge you the same hourly rate as the one working just 15h/week. It very much depends on peoples' own perception of how much work is "normal", and if you ask them to work more then the usual norm they'll probably ask to be better paid (per hour) for extra effort. Which would make them more expensive to hire, which would lead to hiring more 15h/w workers... some sort of equilibrium would surely arise, but only for jobs that are in high demand... unqualified workers will only work more and more...
That's the trouble. From an employee's perspective, I'd like a job with less than 40 hours per week (but also be paid lesson for it). But full working hours are favourable to employers.
You're right but I wouldn't like that even as an employee (which I am). Imagine your that your team triples in size and everyone is in some kind of part-time arrangement that makes it difficult to synchronize any kind of real-time communication. Horror.
It seems easy enough to agree some kind of core - "everyone comes in 2-4pm on Wednesday and we do any meetings then" or some such. I mean, all-remote teams manage to get work done.
I think that there might be huge value in neurobiofeedback but it's a mistake to brand these devices as an aid to what essentially is a religious practice for many people. Just studying the comments in this thread shows that the sole idea of such a device seems blasphemous for some.
Perhaps it would be better to call it a concentration exercise or a brain fitness trainer, especially since it's not even clear that these devices help you with mindfulness (whatever it might be). I tried to find some reviews of Muse done by experienced meditators (I haven't collected the links, sorry) and the results seem mixed. Some claim perfect score on the first sitting, some say they get the same bad results as everyone else starting out with the app. That would suggest that either the device doesn't really do what it claims or that meditation means so many different things to different people that it's not a useful term to use in a scientific context.
It's not just the US doing it. I always read newspapers from both sides of the pond and it was especially entertaining during the big financial crisis. Many European publications acted as if the US is collapsing but Europe will be largely unaffected and American ones anticipated swift recovery for the US and deep EU crisis. Even newspapers that you wouldn't normally associate with nationalistic sentiments (like the New York Times) engaged in some serious fear-mongering.
People also respond to these kinds of messages. I visited the US this August, when the euro crisis was often making the news. Several people were seriously and non-sarcastically concerned with my capacity for paying for my own lunch or hotel. They were very surprised when I told them that the euro is worth more or less the same as always in relation to the dollar.
After having lived 4+ years in Germany and struggling to learn German, I would say that the only way you can learn truly by pure immersion is from your parents. In any other case you need at least some theoretical basis because no one else is willing to spend hours trying to communicate with someone who's basically babbling.
I'm using Duolingo now and after I'm finished with it I want to get some formal classes to (hopefully) get to a B1 level. I wouldn't call Duolingo immersion learning though -- they explicitly provide grammatical rules (unless you're using the mobile app which lacks some features) and it's very difficult and frustrating to try to do it with your intuition alone.
Edit: I think this is the code that actually reads the numbers the user enters, see [0]
function l(){
var a=h.exec(m[1]),f=null,g=null,n=null;
return a&&(null!==a[1]&&a[1]&&(f=parseInt(a[1],10)),
null!==a[2]&&a[2]&&(g=parseInt(a[2],10)),
null!==a[3]&&a[3]&&(n=parseInt(a[3],10))),
new e(f,g,n)
}
Edit(2): Actually, I'm not so sure that's the correct code at all. They NYT game is capable of parsing floats correctly (e.g. it accepts 1.1, 1.2, 1.3 as a "Yes") so it's not just using parseInt.
var rightWrong = (inputData[0] < inputData[1]) & (inputData[1] < inputData[2]) ? right : wrong;
With a variable declaration on line 545 being
var inputData = [NaN, NaN, NaN],
revealed = false,
right = "<p class = 'g-answer g-yes'>Yes!</p>",
wrong = "<p class = 'g-answer g-no'>No.</p>";
And `inputData` is changed on text input on line 662
$("#g-input input").each(function(i) {
var val = $(this).val();
inputData[i] = $.isNumeric(val) ? Number(val) : NaN;
});
It uses the `Number()` function to convert from the input text to an actual number, so it can convert any number format defined by ES5[1] or ES6[2]. So in ES6 you can use binary (0b, 0B) and octal (0o, 0O) formatting along with exponential (1e-2) and hex (0x, 0X). Binary and octal works for me currently on Chrome 43 OS X.
* The number may have optional sign and digits after a decimal point, and may use exponential notation. Example: (-1.2e1, .0E+0, 1.e-3) => "Yes". As seen in the second and third number here, there may be no digits before or after the decimal point, but both at the same time (i.e., ".0" and "0." parse but not ".").
* If the number begins with "0x" or "0X" it is read in hexadecimal, where the digits a-f may be in either case. Hexadecimal notation must not be accompanied by decimal point, sign, or exponential notation.
* No whitespace is permitted within the numeral, even between the sign and the digits as in "+ 11", but both tabs and spaces may be used before and after the numeral without changing its value. In particular, by using a input of the form "1 " it is possible to make rectangular display empty while still parsing it as number. Note that pressing "Check" leads to the numbers being displayed in the rectangle in exactly the same way as they were displayed in the text box, which may depend on the position of the cursor in the text box.
ETA: Also, you mentioned rounding, but there is also exponent overflow and underflow. The application refuses to parse numbers greater or equal to 1.7976932e308. It parses arbitrary negative exponents fine, but it does not recognize that 1e-324 is greater than 0.
A test engineer walks into a bar. He orders a beer. He orders two beers. He orders 999999999 beers. He orders 1.00001 beers. He orders -42 beers. He orders 1048576 beers...
With your example it's easy to lose the distinction between "would eventually terminate if you had a fast computer and a lot of time" and "never terminates even in theory." Here, it definitely looks like it should always run two iterations to matter what the numbers are (as long as they're finite), but it doesn't.
