He discovered a solution to Einstein's field equations that permits closed timelike curves if the universe is rotating.

http://en.wikipedia.org/wiki/Godel_metric

"This solution has many strange properties, discussed below, in particular the existence of closed timelike curves which would allow for a form of time travel in the type of universe described by the solution. Its definition is somewhat artificial (the value of the cosmological constant must be carefully chosen to match the density of the dust grains), but this spacetime is regarded as an important pedagogical example"

Coupon codes, vounchers et al all have one simple aim - to segment the market into two different purchase price points. (there is a spolsky article on this somewhere)

Anyway the point is there is extra effort in collecting codes, clipping the vouchers etc. If you get the voucher automatically added then there is no benefit whatsoever to the company, do it enough, the coupons go away.

Who will collect the codes? Will you enter them into the plugin?
It's certainly a good indicator of smartphone demand, although I'm not sure it's comparable with iPhone 4S pre-orders. I suspect that a lot of the S3 pre-orders are direct from carriers, rather than individuals, so it's more of a 'product shipped' rather than 'product sold' statistic.

I could of course be totally wrong, although as it's a leaked stat it's hard to know exactly how a 'pre-order' is being defined...but in my office (of about 180 people, all mobile facing) far fewer people have pre-ordered the S3 versus the iPhone 4S.
Off-topic, but this really stuck out for me:

I’d set this bar at 50-70% net profit margin. We can aim high because there is no additional cost for each new customer once we reach profitability.

That's a common misconception. You are indeed spending money on getting each additional customer, you are just not accounting for it correctly. It's easy to consider all marketing/advertising/sales/customer service expenses as fixed costs, when indeed these costs go up with each additional customer you on-board.

Also, even if you reach the 50-70% profit margins, how sustainable would that be? The simple law of efficient markets dictates that you will have competitors who will be willing to undercut you. There is no relatively stable company out there that is able to make such margins unless they have constructed entry barriers around themselves (patents, laws etc.).
Computing experts unveil superefficient 'inexact' chip
Are you Danish by origin?

I am well aware that this perspective is completely incomprehensible to Americans, but for us it's just a value embedded very deeply into the fabric of our culture.

I highly doubt that it's counter productive though, as I doubt that society is harmed by expecting you to treat your taxi driver like a fellow human being of equal value, nor that it's bad to have the same expectations of your waiter as you have of your neighborhood college going kid who's just a bit too full of himself.

And yes; we are aware we're chasing away tourists with our service. We're like the French in that respect, as most of us wouldn't mind a little less tourists in town. :)
It's a solution that works for some people - but probably not my mom.

When one considers setting up Live services as part of what Microsoft is offering, it's not a bad deal. Hell, 99 bucks would be a better use of my time walking her through the process.
> OEMs are customers just like the people who actually buy PCs; you can't trivially restrict one without restricting the other.

This is plain wrong. Microsoft dictates licensing with its customers and it certainly has the right to license on different terms to different customers.

And in fact they do exactly this with OEM's already.

MSFT is certainly within its rights and capabilities to include in their licensing dealings with OEM partners terms that prohibit pre-installing what they deem "crapware". And asking them to enforce this restriction (whether a good idea or not) is nonetheless reasonable.

Agreed, which was part of my motivation for entering the field. Also, a reason why I've avoided the sorts of relationships which will tie me to one geographic area.

On the subject of solutions, has our society been incredibly dishonest with this person? Why didn't his parents, teachers, or friends tip him off to the frustrating future of the field he is in? Is this a systemic problem, or is he an outlier? Where have we failed him?

I wish I had more data on this guy and people like him.
When I first became fascinated with incompleteness (following initial coursework in theory of computation), it kind of became my "religion" of sorts for a while. But as many mathematicians lament, the Incompleteness Theorem is one of the most popularly abused proofs of all time - used for non-experts to assert their own half-baked pseudo-philosophy (of course, the same goes for quantum mechanics as well).

These are a few books I recommend:

"Incompleteness - The proof and paradox of Kurt Gödel" by Rebecca Goldstein

"Gödel's Proof" by Ernst Nagel (it's a tiny book, not too technical, but technical enough for anyone with a solid CS background to appreciate and understand)

MS is not charging to remove 'crapware' is some conspiracy with the OEMs.

I suggest that anyone who feels like the guy in this article does get a copy of Think & Grow Rich by Napoleon Hill and read it cover to cover or listen to the audio book.

I've never gone to university and I was much worse off than that guy was success wise, but I managed to pull myself up and I make a living contract programming now.

Don't give up. Also, don't assume that the only correct path is through the front door.
Sorry, but no this is not a quantum computer leap. It's a cute paper but woefully far from a complete solution.

Some problems 1) the procedure appears to require 100 percent detection of photons (there is no analysis of this in the paper). This is not practical and ends up being a source of decoherence (the very thing this paper is supposed to avoid) 2) the scheme depends for its gates and construction of a graph state (a kind of resource quantum state) on precise settings of polarized beam splitters, something which will certainly have errors and hence...decoherence again. 3) the author shows how to create a graph state but makes no mention of why this state will persist. Why won't it deco here while waiting for the necessarily adaptive measurement?
OEMs are customers just like anybody else. If you wanted to, you could start building Windows PCs and installing anything you liked on them.
Money is the reason most things are done. That's why people usually move to higher paying employers & clients. Throw in a nice office, reasonable working hours and I don't care that much what I'm coding if I'm paid well for it - it's an interesting job most of the time anyway.
Not taking sides, but is the article suggesting that there's only a $99 price difference between Macs and MS PCs running comparable hardware? I can assure you it's not remotely close to the case...
Nice play MS. That mean's everybody would think before(about losing $100) removing that crapware/MS trojan. So you actually lessen the probability of them re-installing some other OS on their computer.

I wonder why manufacturers all over the world would rather use FreeDos on some laptops than install Ubuntu or some other linux distro.

Do you think it has anything to do with Microsoft coercing them into not giving customers a real OS choice, or is it because manufacturers don't want to be bothered to do the least amount of effort to support Linux (even though most drivers should work by default)?

There's always friction between ambition and happiness.

A lot of us are ambitious people, driven by the need to out-perform ourselves and build something better. It is then natural to think that you will be better off once you reach that goal compared to how you are right now. The important thing to realize is that more than the goal itself, it's the journey that we tend to enjoy. Once you realize this, having ambitions and seeing a clear path to reaching them is itself joyous.
You're right, I misread that section.
I have a whiteboard wall at my office. Let me make a recommendation.

Don't do it. Paint your wall white, or whatever, and get a big sheet of glass (or a few). Mount that sucker on the wall.

Glass doesn't suck up color the way whiteboards do, and it's easy as hell to clean. It's also cheap as all get out - it's a big sheet of sand, after all. And you can do nifty things - arduino, RGB LED, mild paper backing, and you've got a damn mood-light / whiteboard :)

Anyway, I recommend this to everyone I know that talks about this. A company we sub for in VA did this because I was in town when they were planning the whiteboards for their new office, and they love it.
The only reason to keep them on 24/7 is "they might encrypt on shutdown", so if they powered them off they wouldn't now need to keep them powered up.

In my experience, the resume is so thoroughly designed to be rejected that you basically can't rely on it. I don't know how ordinary people would actually get jobs in this market by simply submitting a resume for an open requisition; there will always be someone out there whose resume has less HR red flags on it (probably because they falsified it) so you never even get an email back from hiring.

100% of my job opportunities have been from networking (or nepotism) and most of the people I know have the same experience.
Maybe for the same quality, it is. Ultrabooks comparable to MacBook Air are only $100 cheaper, maybe $200 at most at the higher end, but I think they achieve that also by skimping on some stuff (display quality, SSD, etc).

Please tell me when it was ever easy. Rumors of the job market being easy in the past are vastly overstated. Before the Internet, before entry to IT was as easy as it later became, I graduated high school as valedictorian and took the highest paying job I could find based on my skills: factory labor in a box factory. I got married a year after high school, we had a son, and THEN I started junior college. Before I got my associate degree in IT 3.5 years later, we had two more children. I worked the factory job for 5.5 years. When laid off, I worked in convenience stores, chem labs, other factories, whatever I could find (and finding short-term work was not easy--sometimes spent weeks finding a job, only to be called back to the factory.) In my last semester, I worked an unpaid internship in a bank IT department while still working the factory job at night. The bank hired me. I have worked on the same software, following it from owner to owner, ever since. I have done extremely well. But I was in no way prosperous until I hit my mid-30's. We lived in apartments for years, then a mobile home, and finally a house when I was 31. So from age 19 through about 35, you might say it was a struggle. It's not that I don't sympathize with 20-somethings who think they have it rough, but I would like to tell you that for most people, getting along is NOT easy and NOT guaranteed. This whole business of getting the right degree and then networking your way to fun and glory--if you can pull it off, cool. If not, perhaps you ought to start grinding at whatever you can, save up some money, and keep grinding for the chance you want. Oh, and get off my lawn (kidding--I know I sound like that guy.) Good luck, but more than that I wish you the benefits of every second of your own efforts--eventually.

You need a good operations team with the authority and willingness to say "no" with overrides coming only from senior management, the authority to say "yes" for the obvious stuff, and a direct line to senior management for grey areas they're not comfortable making a call on by themselves.

The operations team will spend a few months saying "no" a lot and justifying their decisions to management. Eventually it will slow to a trickle except for a few really stupid people who lack reading comprehension and any sense of pattern detection. Management will eventually get tired of it and forbid the stupid ones from making hot-fix requests.

Just have a plugin like https://addons.mozilla.org/en-US/firefox/addon/bugmenot/ that works with http://www.bugmenot.com and instead of suggesting logins it suggests coupons. (add: in fact look at bottom of bugmenot -- retailmenot - wow, never knew about it: I wonder if it works well with the plugin)

I don't know how the mechanics of the plugin are going to work but it'd do 3 things: suggest codes for the correct field, send used codes back and whether successful or not, also check whether used codes are already in database. Who supplies the codes? E-commerce sites to distribute a new coupon codes, and they could also tag certain fields for the plugin to suggest upon and tell it their coupon submit page. What happens if ecommerce sites don't actively participate: it doesn't matter people will give to get. In fact, there could be a karma system: supply a working coupon and get karma the more it is used. Use someone else's coupon and lose karma.

The only hard bit is working out where a code must be entered and determining if it was successful - but sites don't change that much and that could be crowdsourced.

Even though I'm not a Christian, I'd certainly consider that valid advice.

Let's not forget how we got here. In the mid-1990s the OEMs were up in arms about how Microsoft was trying to control the Windows user experience; the OEMs said it was their customer and they would install any damn thing they wanted before delivery, thankyouverymuch.

The DOJ's 1994 consent decree with Microsoft [1] said "Microsoft shall not enter into any License Agreement in which the terms of that agreement are expressly or impliedly conditioned upon ... the OEM not licensing, purchasing, using or distributing any non-Microsoft product." It reinforced that Microsoft could sell Windows to OEMs but not dictate what else went into the box.

And thus began the crapware nightmare. It was all well intentioned, but it prevented Microsoft from taking an Apple-like role of "benevolent dictator" to keep the OS coherent. So instead, Microsoft is relegated to the role of curmudgeonly custodian, only able to arrive and do something after the mess is made. A Groundskeeper Willie if you will.

Chipset	Exynos 4212 Quad
CPU	Quad-core 1.4 GHz Cortex-A9
GPU	Mali-400MP

http://www.gsmarena.com/samsung_i9300_galaxy_s_iii-4238.php

The Mali-400MP is quad-core (x2 from before) http://en.wikipedia.org/wiki/Exynos This seems feasible, with similar battery life, as they've shrunk the process to half the area: 45^2 vs 32^2.

Its performance per core is comparable the sgx543 of the iPhone/iPad.
http://www.arm.com/products/multimedia/mali-graphics-hardwar... vs http://en.wikipedia.org/wiki/PowerVR#Series_5XT (though depends on the clock actually used)

So, this phone's GPU is similar to the "new iPad"3 (quad-core sgx543). (Apple have also done a shrink, but it's only used in the old iPad 2 so far...)

I think quad-core CPUs are past the point of diminishing returns (consider the latest Transformer); multi-core are still hard to code for, and they are usually underutilized on desktops.

Note: the iPad 4 is likely to have the next in the GPU series (Rogue 6200), which apparently is comparable to the xenos GPU in the xbox360. So, it's leapfrog, jumping x2 as far each year.

I read that as he's Ex-Christian, not currently Christian, so such advice would not be considered any more valid than the Tao Te Ching.

Maybe, but one does not simply turn off 25 years of spiritual training and knowledge like a light switch. There is plenty of good practical wisdom contained in the Bible, especially in Proverbs + Ecclesiastes.

My hunch is that while Ryan has an emotional issue with the concept of people being held accountable for our moral choices (i.e. justice being served at the end of life), mentioning Biblical scripture here wouldn't be like throwing "pearls before swine" -- he seems like an open and smart guy and probably still has some level of respect for the Bible.
So he's an excellent learner and has a background in the field, and you're not willing to train him or let him learn on the job? "his ability to actually apply or use them to a problem weren't" probably describes 95% of college graduates.

I think in many ways it's easier for people like me who have non-vocational degrees. I have a theater degree and I knew I'd have to build a career in a non-traditional way. I was never under the delusion that the thing that I enjoyed studying was going to pay my bills.

My "career" started in a Dell call center (although I had many service industry and manual labor jobs before it) and through various vertical and lateral moves has led me to be a senior software developer.

My degree in theater has been extremely useful and a strong selling point in pretty much every job I've applied for. I can talk about my acting classes as being useful when talking to customers. I can talk about classes in design and construction that show a proven track record in taking abstract ideas and translating them into full products.

There's zero use for a vocational degree in a global economy. There's only value in having an education.
I'm going to assume, since the newspaper is Canadian, that he's Canadian, like myself. He is also near to my age. There is ample work in our country, but you have to be mobile and willing to do labour.

It sounds to me that this fellow's problem is this:

>" I wanted the tailored suits, the chance at a high income, the BMW, the prestige, the respect, and the power."

Yet he wants that opportunity to be given to him, rather than going out and making it happen. He seems entitled, after graduating from University, to these opportunities. That ship has sailed. Our (my generation) father's worked in labour and helped create the middle class of North America. Why are we so against it?
No, sorry. I should have said it was later than 1994; probably around 1998.
Tools Are Top Priority
There are two flagship applications for quantum computing: (1)Shor's polynomial-time factoring algorithm and (2)Grover's unstructured search algorithm, which has O(√n) running time [classically, if you have an unordered array of n elements fining some element is O(n) so it is a √-speedup].

Both of the above are //theoretical// applications, but the letter agencies seem to be confused about this and think they can actually computers that carry these out. All the quantum researchers working for the US military deserve a Nobel peace prize for all the money they are diverting from actual weapons and shit.

My opinion is that (3)quantum simulations of physical systems will be the most useful part of the quantum computing industry. Also, quantum optics is very cool, and could lead to higher throughput for optical communications.
