Computer programming is not such a fundamental area of study that it deserves to be elevated to the level of "math", "reading" and "writing".
To actually do some programming, one'll already need some "math", "reading" and "writing". And, IMHO, having coded a working program is a good incentive for kids, as it reinforce their sense of "control over something" - to put it briefly: in regards with derived satisfaction, "make install" seems some levels up over "make believe".
Besides, the writing in the Estonian language is mostly phonetic (every grapheme corresponds to one and only one phoneme). As a result, learning to read/write is highly simplified over some other languages. Thus kids are done with reading/writing by grade two in elementary schools, with no effort invested up to the middle school in spelling (yes, that's right, spelling bees are rare to nonexistent in countries whose national language follows more phonemic spelling rules).
While I'm not Estonian, my maternal language is also phonemic: I started to learn reading/writing at age of 6 and my first book I ever read all by myself was a translation of "The Hobbit" at age of 7 (granted, took me two whole months; but, since then, I was not dependent on anyone else to read books - other than, perhaps, to get a book from a shelf too high for me).
Same calculation knowing that the solar constant for Earth (1 AU) is approx 1 kW/m2 results in a 137 W/m2 on Ceres (put on top of it the 20% efficiency of a photovoltaic and you'll get... what... 27 W/m2?)
Isn't part of the 1kW/m2 on Earth due to the atmosphere absorbing some of the energy?
Yeah... - my lazy ass didn't want to be too exact: the solar constant as seen by a satellite is approx. 1.36kW/m2. Which means on Ceres it would be 186 W/m2.
Ceres wouldn't have that problem.
I wouldn't be so sure: it can actually be worse due to the water subliming at "day" time (a "haze" which would create an absorption - mostly in IR and UV) and condensing back at night time.
Now, if the sublimation/condensation process is not energetically balanced - and because the PV "steal" some energy it is definitely not balanced, thus the condensed ice on the PV won't get the energy to sublimate entirely - it is very likely that the PV panels will get covered in ice pretty quick (BTW the Cererian day is 9 hours and 4 minutes).
Abundant water and energy are the two essential keys to human and robotic exploration of the solar system.
I can see the water on Ceres, the energy part is a bit tricky.
- Mars-Sun distance - varies between 1.38 AU and 1.66 AU (say 1.5 AU as an average)
- Ceres-Sun distance - varies between 2.55 AU and 2.99 AU (say 2.7 AU as an average)
With a variation of of irradiation going with the inverse of square distance => a unit of surface on Ceres receives 3 times less energy from Sun then the same area on Mars. Same calculation knowing that the solar constant for Earth (1 AU) is approx 1 kW/m2 results in a 137 W/m2 on Ceres (put on top of it the 20% efficiency of a photovoltaic and you'll get... what... 27 W/m2?)
Which leads me to believe one is not going to get the energy for getting LHOx from Sun - ''t'll take ages to get something significant or deployment of a quite large area for capturing Sun's radiation. A fission (thermo)pile then? For a non-trivial power, it will be heavy like hell to raise it as such from the bottom of Earth's gravity well - maybe as an intermediary step, build it from materials found on... Vesta or the like? Or build/launch it on/from the Moon surface?
...Ceres is half water ice by volume, in low g. Obviously some serious upside potentials there. A vastly superior target to Mars, or just about anywhere else in the solar system.
Upside potentials? Care to expand a bit the topic?
The more the ones who can afford armies of lawyers will win.
And once the government starts regulating the internet, there will be literally thousands and thousands of pages of regulations.
Tell me, how does that help the consumer?
The more complex one makes the rules for the WiFI space, the better the chances for the non-representative minority of customers that chose to stay wired will be...
Why increase the wall size when you can simply produce a can with less pressure? Essentially that would lead to comparable results considering that the pressure difference between inside and outside the can would stay equal.
My guess... it's not about the pressure, it's about the volume of propellant that is able to displace/move/spray the entire content of the can.
Of course, one should probably first find out how the rest of the stuff reacts when subjected to zero bar air pressure instead of one.
Some info - mineral oil, probably won't evaporate. The rest (alkans fraction, CO2 propellant)... a low vapor pressure (the alkans fraction) and a somehow directional spray (assumed to hit an obstacle) would saturate a volume quite quick (even if not enclosed). But... the temperature of the surface is the biggest problem - the most volatile is the CO2 propellant and -57C/-109F will surely cease to be a gas. The rest of the components will most probable make a jelly at the contact with the ISS surface.
I can barely be hassled "typing" any more than 3-4 sentence email on an ipad before I get annoyed.
Tablets are great for some things (content consumption primary amongst them). But honestly, any time I am told that tablets represent a "post-pc" world for content creation (whether professional coding, or simple word processing), I just laugh.
Joking aside for a moment, wouldn't the can explode if you took it into an unpressurised environment like space?
The "void" of the space is only 14.7 PSI lower than at the sea level. My guess about the typical pressure in a spray can: around 80-120 PSI - this taking one into space will only raise the pressure difference by 18% - easy to compensate with a slightly thicker wall.
Even if you did, wouldn't the propellant immediately evaporate the moment it left the nozzle?
I wouldn't worry about the propellant, its job is to propel; the higher the "exit velocity" the better the transport/dispersion... At most, the "propelled" would matter - one will need to consider the vapour pressure of it while working at the temperatures in space (maybe the danger is not excessive evaporation, but the freezing once it touches a quite cold surface).
Why do I feel more and more like I'm a Chinese citizen and not an American citizen?
Hmmmm... yes... let's deregulate the use of spectrum and let the companies actually "compete" for it... freely, no rules, interference and jamming and, why not, hitmen and private armies should be allowed.
Does somehow the concept of commons rings to you too close to communism?
The larger question, unaddressed in this patent, is whether we want our individual personal data to be tagged, filed, and logged without permission or choice."
How is a video uploaded to youtube 'individual personal data"? Sometimes it seems like we just want to complain about stuff.
True. A bit further and someone will question whether the objects (captured in the clip) themselves may or may not... well... object.
I mean... can you imagine the shame of a jiggling conical green jelly object to be tagged "dildo"? (spoiler: no pr0n was linked in the course of this posting).
The issue may originate in the people that think of them as "being right and moral" and thus tend to throw too many stones ("he who is without sin among you, let him be the first to throw a stone at her") without realizing they are actually doing it out of frustration accumulated by "living a moral life" (e.g. denying their body what their body asks from them).
I bet it's not about the encounters but all about the lesser sexual stress/frustration... but a solid amount of safe sex is likely to be good for health. That would be my theory at least.
"That would be my hypothesis at least."
FTFY. It's not a theory unless tested, and survives reproducibility over time.
Why... you only need to look at the US politics... Clinton - less sexually inhibited - fucked only inside White House. Bush - a moral methodist - fucked the entire world. Which times were better?
No, seriously (large-grin-with-tongue-in-cheek)... I'd say the entire world would be better if the nomination for the US presidents would include elements regarding, at the very least, the presence of an active sexual life.
...interfaces like Android (especially Honeycomb and later) or Microsoft's Metro, things have been taking a sharp turn away from skeuomorphism and decidedly towards an unabashedly digital styling.
Agreed. Call me decrepit, but I reached the point I consider paying for some actual styling.

Why would one want all kids to know programming?
So that they can create Web sites linking to "pirated TV shows" and hack xIAA/Sony/Strafor/etc while young, without being afraid to go to jail?
You'd better start teaching your kids to defend them (that is... if they don't find much funny to hack them too).

In other words, IE and Chrome do not implement the data URI to the specification.
Lucky them, they can pose now as "more secure".
Considering all the trade and economical sanction, and the collapsed economy, where does North Korea get its computers from?
Up until recently, I don't know... however, I can guess that they'll mostly get them from Iran from now on.

Careful what you wish for: the descendants may put his body on an Earth orbit - high enough to keep it off the ground for some millennia.

How did you unlocked your bootloader?
Cyanohydrogen mod. Use with extreme caution, in most of the cases causes brickage. And no, I have no link to it.
Also, where to I do I find an early ROM, I recently got a baldness bloatware update and haven't been able to remove it.
Upgrade to GirlFriend 2.0 - once you've done it, the brand new troubles will make you see your current problem in its true light - i.e. insignificant.

Meanwhile I am going to go patent air, water, and boobies.
Sweet... I can patent the earth and the sea bottom, as well as other bottoms - no worries... cross-license and FRAND.

'Silicon Valley proper is soul-crushing suburban sprawl,' ...
And a city is "soul-crushing urban sprawl".
Big difference!
But... are there many suburban homes with basement?

Gravity is also inconvenient and confining. We need to rally the people to overturn this law.
Repeal the first (or even only the second) law of thermodynamics and we'd get enough energy to beat gravity.
However, there *were* reports of an SOS...
Yes... actually a hundred billion of them... stingy luck to have found only one of them.
