What are you studying? What Uni are you at? How are you spending your spare time? Are you already learning Ruby? PHP? Python? Do any uni departments offer service courses in these subjects?

Uni isn't for everyone, but there's a lot to be gained if you use your time well, far, far more than you think. If you want to be a freelancer/entrepreneur/business person then you need to be able to think laterally, and make the most of every situation. Uni can be expensive, but there are more opportunities there than there are outside.

And speaking entirely for myself, you'd make a better impression if you correctly put apostrophes in "it's" and correctly capitalised "I". These things make a difference if you want to impress people and get them to give you money. The impression here is that you don't pay attention to the sort of nit-picking detail that makes a difference in a web site.

And if I sound harsh, wait till you get your first real client from the wild. And in the interests of full disclosure, I got a PhD and did enjoy my time at university, but I did a lot of stuff outside my coursework/studies, and the benefits from that are still being felt 30 years later.
It's not that I won't read up on their inner workings. I do. Compiler writing is a hobby of mine, and I love reading up on new concepts in relation to that. I've read a lot of the original papers for Haskell for example. It's that I won't bother learning to program in them any more - I find it wasted effort.

Haskell was a particularly obnoxious one - I love a lot of the concepts, but I find it horribly slow for me to read. I got so frustrated with it that I implemented a small little lambda calculus interpreter to play with the concepts because that ended up being an easier way for me to learn them than to wrestle with Haskell.

Personally I don't think Haskell will ever become mainstream to a large extent because it is too hard to read for people who are not maths geeks.

What is the maximum number of children a man can have? What is the maximum number of children a woman can have? What does this imply about the best strategy for maximising number of descendants for men and for women?

Male mating strategies exhibit far higher skew than female ones. Men have higher variance than women in every trait I know of, from heighth to IQ scores to income. Men take more risks.

Sweden's IDG.se had an article recently on some enthusiasts building a 737 simulator. Article in Swedish, Google Translate might be helpful: http://www.idg.se/2.1085/1.441624/sa-bygger-du-din-egen-flyg...

The web site of the society who built it: http://www.swesim.se/

The 737 isn't the only simulator they've got, among others they have a Viggen simulator (http://en.wikipedia.org/wiki/Saab_37_Viggen).

I disagree. Those devices were very usable but, of course, you needed 2 hands to do anything with them. You could do a lot of stuff with it, and a number of apps were way more advanced than what you see on android and ios nowadays. The finger interface has got much better, but a stylus was way more precise for many purposes. The surface covered by a finger induces great limitations to the interfaces you can create. There's no miracle.
Precisely -- I have argued before that crowdfunding is not an option for a startup or any other commercial activity. But if we see it as selling in advance, than it makes all the sense, and pricing and everything should be set up just as if they were selling an existing product.

However, if Kickstarter doesn't allow changes in pricing once the project is set, it might not be the best option. Why not simply set up a personal pre-selling page, accepting payments via PayPal or any other service?

I'm curious about the infrastructure investment necessary for commercial space flight - over and above developing the launch system and vehicle itself - and how this affects the economics of the business.

How do SpaceX communicate with the Dragon in orbit? Have they built their own global tracking/control network? Or do they use ground stations developed for commercial satellite control? Are existing (non-NASA) networks suitable in terms of providing uninterrupted connectivity with an orbiting vehicle?

Also, is sharing of ground facilities (fueling, launch, recovery) with other operators necessary for the business to be economic?

Clearly these people did not see the same Jan 2007 demo that I did. Grown men were going apeshit in the audience and millions around the world were glued to their computer frantically refreshing live blogs. My entire office officially stopped working to "watch" the keynote. Hundreds of thousands were already talking about dropping Verizon for the iPhone. Hindsight is 20/20, but no one in their right mind would've predicted it would fail. Apple sealed the deal when they finally subsidized the iPhone in Sep 2007.

The opposite happens, too. I heard a story of how Chinese buyers bought an old, unused steel mill - think it was in the UK - and shipped it wholesale to China. The technology used in that mill would still be profitable in the Chinese environment, even though it had been superseded in the UK.

All this shipping of buildings back and forth...this clearly needs disruption!

Sorry, I don't get your point.

You can be successful with your product on the WWW without employing any Google services, being totally independent. If people and other sites like you and link back to you your traffic will quickly skyrocket—which feels natural. You are not obliged to use any Google service like GA. Just use the Internet and its open standards and you are ready to go because Google left the Internet's core like it is and didn't build a walled garden around it. That's the great thing about the web: it's decentralized and everybody can contribute, Google haven't tried to change this. That's why I don't like the native app trend with the appstore, all the innovation the Internet brought us are vanished by one central and strict entity and nobody cares, Android at least tries to emulate some parts of the net (i.e. by using intents, allowing multiple appstores, with the open nature of Android, etc.), Google is regarding their marketplace Play much more relaxed than Apple.

Looking at the Appstore or the Facebook API, there are so many rules which don't follow any of the core principles of the Internet. You have to play by these rules otherwise you are banned or completely and utterly dependent of one single entities. Moreover, if you then play by Apple's or Facebook's rules you still do not get the impact as from Google traffic-wise.

Ultimately, Google haven't entered the Chinese Market which shows the company's values. Every larger western corporation have build joint venture based branches in China—every corporation, except Google—and that's distinguishes Google.
The benchmark was very much about whether you CAN scale if you need it. You'd probably not rent this size hardware at Amazon if you needed it on a daily basis. So $26,784 is probably not realistic.

At any rate, as I mention in my longer report on the benchmark [1] the high total translates into very LOW hardware
requirements for lesser needs. The number to go by may rather be "10k+ TPS per core for linear scaling ACID transactions." I think that's the number that matters. Linear 10k+/core ACID TPS.

WSJ seems to have made a recent change to stop the old search-for-the-title-in-google trick. If you visit the article first and then leave and come back with google referers it doesn't work anymore. But if you've never visited the article and you come from google it does show it. Even when you delete your cookies and then try to come via google it won't show the article. That means they're using flash cookies or some other insidious persistent cookie technique. Not sure if this violates Google's terms.

Refreshing response from Sergey. The Guardian article made him come off very immature.

The article brought to my mind a presentation Roger McNamee (Elevation Partners) has been circulating -"10 Hypothesis for Technology Investing."

A number of the points in the presentation illustrate a challenging future for Google:

- Index Search has peaked: Google's position of dominance on the web is fading, due largely in part to their own success.

- Apple's App Model Threatens the World Wide Web: a walled garden, un-indexable

- Rise of Social. Facebook owns. Again, a walled garden, un-indexable

- Lack of searches on mobile

Similar arguments were made in Wired's "The Web is Dead" feature, and they all point towards Google's core business going downhill.

The Guardian article made Sergey seem... well... butthurt. As if recognizing his lousy position, but instead of owning it, whining about it. I've always thought of Sergey as smarter than that. He's always seemed much more pragmatic than The Guardian article made him out to be. It didn't feel like the Sergey I [don't actually] know.

Certainly Sergey has gripes with Apple and Facebook, and certainly he has self-preserving motivations for responding as he did. But I feel like giving him more of the benefit of the doubt here and calling slight nanz on The Guardian for rabble-rousing as press outlets do.

Also - kudos to Sergey for his extremely diplomatic clarification there. We've all seen much less tactful responses to press spins.

I was so looking forward to a more 'web like' replacement for Ceefax/Teletext, to augment broadcasts. I never use the digital TV red button as it feels even slower than the 70s technology.

Add to that that I can't even read what is on the screen. At least I can read Ceefax. Perhaps it is because I don't have a TV display larger than 22".

The company that can add useful overlays to existing broadcasts - could clean up: think Twitter/Wikipedia on the telly. A use for something like raspberry pi?

Pages using bleeding-edge tech like this need an easily accessible fallback. I can't find any way to access the content from that Beercamp page in a non-busted-3d format.

Article's example of correct 'depth-sorting' isn't demonstrating depth sorting, since depth sorting sorts entire elements to the front/back - interpenetration isn't possible. For interpenetration like he demonstrates, you have to split scene elements up into smaller elements or depth-sort at the pixel level (modern 3d cards do something resembling an approximation of this via the z-buffer).

Nah, there's wind, and the ocean. Less humid air evaporates ocean water quicker, and the wind will circulate the air till it eventually reaches the ocean.

The Earth is enormous, it would take a staggering number of these to make any dent in humidity, and even then it would be a local dent only.

Don't forget water is a closed loop - this water they consume is also eventually returned to the environment (sweat, etc.), where it evaporates and restores the humidity.

Probably the most interesting thing about Ceefax and the other teletext services was that it was a wonderful hack using the Vertical Blanking Interval between TV frames.

See http://en.wikipedia.org/wiki/Vertical_Blanking_Interval and http://en.wikipedia.org/wiki/Teletext#Data_transmission

The VBI itself is a hang over to slow technology used in CRTs: The VBI was originally needed because of the inductive inertia of the magnetic coils which deflect the electron beam vertically in a CRT; the magnetic field, and hence the position being drawn, cannot change instantly. Additionally, the speed of older circuits was limited.

The idea for Ceefax came from the BBC who were researching ways to send subtitles for the hard of hearing: http://en.wikipedia.org/wiki/Teletext#Development

A ton of assumptions peppered with a pretty glaring lack of substance. So "Microsoft is making radical changes"? You mean different from the last "too little, too late" campaigns they had?

Reads like an ad for investors. Like something that is promised for the future and we will enjoy if we only hold out and believe. Sounds like the tune Microsoft has been whistling for decades now.

> That's the world for which Microsoft is building Windows 8. It can run everything from a touchscreen app like Angry Birds to resource-intensive software such as 3-D games and video editing tools. That sounds simple, but it's an all-in-one approach Microsoft's rivals have chosen not to pursue.

No, actually that sounds almost entirely meaningless.
No, that is not the next step. That is a silly step.

You need a lot more water as water than you do as hydrogen. For hydrogen sea water is more reasonable, and transporting it isn't a problem since you don't need much.

In any case, hydrogen can not be energy storage since it leaks too easily. It also damages any metal container it's stored in (and leaks right though plastic). Glass might work.

Try per unit of water, so you can make meaningful comparisons. Desalinated water apparently costs/is priced at USD $2-3/meter^3 in the UAE [1,2] (0.2-0.3 cents/liter), so 1,000 liters/day => $2-3/day or ~$1,000/year.

A large UAE desalination plant for comparison [3]: natural-gas fired CCGT piped to an offshore gas field, 1,430 MW electricity, and 380 million liters desalinated water/day (~$1 million/day or ~$300 million/year), presumably from waste heat.

Average per-capita water consumption in the UAE is 550 liters/day [4] (so ~$400-$600/year?) -- actually among the highest in the world, comparable to the US. The point probably being that their GDP/per capita is also comparable to the US, so the desalination cost isn't that big of a disincentive.

I'm pretty happy with the Crypto class Coursera is running right now. The lectures are pretty info-dense and the homework promotes at least some thinking.

I think it's better than the AI class I did the first go around.

The best of these classes for me so far, though, is the MITx class on circuits and electronics. The professor is fantastic- great at explaining things and obviously having fun teaching the class. The homework is challenging, at least for me, and I feel like I'm learning a huge amount. Very very pleased with that one.
Forget the stupid writing in the article. The reason why they may be using the wind turbine directly is if they're using mechanical energy to fire the compressors, etc to run the process.

Compression of the intake air is likely best served mechanically. Cooling the air could be served mechanically, although an air conditioning compressor is likely better designed to run electrically, but again it depends on the scale used to determine if mechanical would be better or not.

Although I'm wondering if the compressed air itself could be used to power the condenser. If the air is compressed enough, would an appropriate design allow the expansion of the compressed air to cool the condenser it's escaping from? Because I know air compressors for air tools build up water inside, and they are purposefully designed to inhibit this.

Also the reverse-osmosis, or whatever filtration used, is likely best served by producing the water and letting it filter down through gravity pressure under the 30+ft drop from the unit to the holding tank.

Although, it would be more ideal to produce say 200L a day and produce energy too so that a few of these would provide water and electricity to a village and everyone won't die when their water producing turbine breaks down and takes a month to get repaired.
