Zuck has talked about this publicly: He foresees Facebook.com fading, and Facebook's social graph to the be the thing that powers every quasi-social activity on the internet.
The papers I've seen point to values larger than 15~30% - I've seen ~50% cited for geometries as large as 65nm, only to get worse as we go to even smaller feature sizes. [1]

Threshold voltage is not really an effective knob, unless you assume that the feature size to be a knob and go against Moore's law, or that brand new, once in 10-years process innovation is a knob that designers can pick out of a hat. I don't think anyone's clamoring for return to 130nm parts on a smartphone. At each new process node, you're going to lose out on the amount of control you'll have over Vth.

This is basically what Intel did with the tri-gate transistors which gives them longer lease on life until they bump against subthreshold leakage. TSMC is on their first generation high-k metal gates, and still a process node or two away before jumping over to the tri-gate party.

I have my own auth system that I use in all of my other projects. Why on earth would I send users to, and trust, a third party?

That seems like an extra headache. It makes sense for me to do it with facebook because it's really easy for users, and because there are benefits for the users when they do it (and for me).

(These benefits are: they don't have to rebuild their social network, again)
The lower bound is Omega(n^2 lg n), but waiting for an algorithm (if there is one). Ref: Ran Raz - http://dl.acm.org/citation.cfm?id=944299

I agree with you - checking if a user is logged in, authorization, validating the request, choosing the right view to handle the response (html, json, csv, redirection if you just did a POST and so on), these all belong in a controller action. The framework can be smart about it, relying on conventions and all that, but if there's one thing I've learned is that the rules are meant to be broken and I never met a project that fit perfectly in the sweat-spot of any framework (which is why I do not think middleware cuts it for specific scenarios).

To me the rules are pretty clear:

* data-processing stuff belongs in models
* business-logic belongs in *business models*,
if said logic is related to the UI (i.e. repeat-password),
although for simplicity you can choose not to bother
* request processing (authorization, choosing the models,
choosing the view) belongs in a controller action
* response processing belongs in a view

Regarding view forwarding, I once had a request that based on a parameter, instead of rendering HTML it would forward to a view that sent an email to the user with a CSV file attached, then redirected to a notification message. But only if the user was properly authorized. So the controller's logic was getting reused, forwarding to multiple views depending on expected output. Now that's a real controller and a real view.

Intel is most certainly not using AMD's architecture, they are using AMD's instruction set, yes, but they internals have nothing to do with AMD's designs. The Core series was an evolution of the Pentium M which was based on the Pentium III architecture.

I find messages that close themselves very inhumane; I can easily miss them if I look away or switch tabs, or they can disappear while I'm trying to understand them, with no way to bring them back.

My top feature request would be a 'stays up until dismissed or navigated away from' option.
Thanks mate. I tried it on vimeo.com (as author suggests) and it doesn't seem to work.

One point is: The UI is somehow broken (no styling, and "application settings", "update" and the checkboxes each are on their own line).
Second point: When removing the ticks from the checkboxes and click on update, I'm redirected to:
"https://www.facebook.com/dialog/undefined/dialog/permissions...

so "dialog/undefined" needs to be stripped.

For all those people who are not getting it. Today success of most software shops is about business innovation not technology innovation. Yes there are instances of Google and other big web giants innovating greatly in the technology area. But they amount to less than 1% of the software crowd.

We are all writing software to solve business problems. We are not writing software for Software innovation.

Unless you are doing something special. Most software today is written in IDE's. You don't have to remember syntax at all these days. The IDE will do it for you. It knows what libraries you want, it knows how many exceptions your code can run into. It knows how to compile, build and package your code. I can give you your code coverage. It can even do documentation for you. There is hardly anything IDE's can't do these days.

All you need is a little semantic awareness. And there are solutions to nearly every problem you are likely to run into a software shop. There are libraries, API's and frameworks that have understood and defined your problems as a generic case and solved them. There are forums to help you out on edge cases.

All you do these days is know a solution to a generic pattern of problems. You fundamentally pull out those logical solutions from your brain and parameterize them for the solution need at hand. And remaining is simply IDE play.

Very little or really a non quantifiable of highly intellectual work is happening in business based software shops today. Google, Facebook are exceptions, not the normal.

And this isn't surprising. We need armies of programmers to do all the bulk of the business job out there. If you are still thinking that as a software guy you are going to work with math theorems, then you have got it wrong.

Given all these, my success depends on only two things. How much aware of the reusable solutions. How quickly and how many problems can I solve using them. Which is productivity.

This is drag and drop programming demystified.

How I made 1231$ with my Twitter account this month
Just to chime in with a little more strength than an invisible upvote, this is one of those things that doesn't sound to annoying until you're experiencing it yourself.

I used to read reviews complaining about it and think "stop whining" to myself, but now that I'm ready books that I paid for and which clearly went straight through OCR software with no human supervision... Really, really frustrating.
Does that app still work with the current version of the OS?
Django also calls the functions/classes where you define the logic of selecting the models to operate on, validate, pick output, etc… a 'view'. The template where you map the data to html is just that: a template. People coming to Django from Rails often get confused by that. In the end, it's very similar but with a different name.

I'm reminded of the old Microsoft Foundation Classes with their Document-Object model that lacked a controller. Their promise was that you could reuse views and documents but in practice the lack of a controller to handle user input meant you never could. At least, I never could.

The pumping lemma is cool, but the Myhill-Nerode theorem is more powerful (as someone mentioned).

I think, too, that what was meant by 'contrived' was that the pumping lemma is not really an equation. But you don't get hits if you talk about the top ten theorems CS geeks should know...

It will be interesting to see how stricter data protection laws play out. The EU will make a new data protection directive in 2012/2013, and other new laws like in Singapore or HongKong are more influenced by the EU standard than by US standards - because otherwise they may not get outsourcing work from EU. But I still agree that the facebook data is likely to be very valuable...

One of the EU ideas is to give the user a right to "export" their personal data. If there was a functionality where it took you 1 click to recreate all your facebook-data on "SocialNetwork2.0" the switching costs would seem to be very low. I sometimes feel that network advantages are overestimated. Here in Germany we had the facebook clone "StudiVZ" a few years ago, and practically all students were members. Nowadays Facebook dominates here too and many new students don't bother joining "StudiVZ" anymore.

Yes. Intel has more than made up for the mess they were in circa 2003-2005, but the fact remains that AMD was able to truly embarrass Intel for quite some time, both by beating Intel to market with several new technologies, and by significantly eroding Intel's market share for desktop and server chips.

Well, consider someone who immigrates and subsequently has a family. One doubts this ship would have appropriate medical, daycare, or school facilities. Sure, most startup minded are likely single and focused on business, but non work considerations are important to many people. Under current immigration law, family members of green card holders and naturalized US citizens get preference in visa allocations; whatever you think of this as policy, it's certainly a significant benefit for some people in the country of origin which wouldn't be available with the sea borne approach. Likewise potential business or investment partners in a non-US country would probably prefer to deal with someone who has a secure foothold in the US capital or retail market. Speaking as someone who has lived in several different countries, the difference between being a tourist and being properly plugged into the local and legal infrastructure you are working with is huge.

Simon's Win32 Cheat Sheet
Who cares what the top supercomputers are powered by, what matters is the market. I'm fairly certain that numerical simulation systems do not dominate the high-end computer market. Instead, it's still all about servers that spend most of their time shuffling data around, which intel platforms still do quite well at.

Additionally, intel still has plenty of time to get up to pace in the mobile market. The tablet market is as yet largely untapped, especially globally. I wouldn't be surprised if next gen atom processors made their way into leading edge tablets in the next few years, for example.

Generally speaking: forecasts that require intel to roll over and take a massive beating while billions upon billions of business leaks away to its competitors don't tend to pan out in reality. The only way that works is if intel goes bankrupt the instant a competitor comes on the scene, and that's just fantasy.
"Statistical significance" is starting to tire me. It is too binary for my test: either a given result "achieved" statistical significant, or it is not. Obviously you have to choose a threshold, and which it should be is much less obvious.

Couldn't we just do a way with statistical significance, and just publish likelihood ratios, or decibels of evidence (in favour of one hypothesis over another) ? That way, we should know exactly how much an experiment is supposed to be worth. No arbitrary threshold. Plus, you get to combine several experiments, and get the compound evidence, which can be much stronger (or weaker) than the evidence you get from any single one of them. And then you may have found something worthwhile.

This is especially crucial when said evidence is expensive. In teaching, for instance, one researcher can hardly do experiments on more than 2 or three classrooms, over little more than a year. This is often not enough to accumulate enough evidence at once for reaching statistical significance. But a bunch of such experiments may very well be. (Or not, if the first one proved to be a fluke.)

That’s very interesting. Wouldn’t it be very easy for Apple to break the app with an OS update? You would almost expect that an app stops working after so many OS updates (not because someone purposefully made it stop working but rather coincidentally).

(note: Mexican immigration law is much harsher on the undocumented than US law, but much easier on legal immigrants so get your papers in order when you try this; it's pretty easy.)

Actually, Mexico reformed its immigration regime a few years ago, such that it is now decriminalized and involves only a nominal fine. Not that you'd know it from reading US media, which doesn't cover Mexican politics very well.

IMO what's missing in the search space is a web search engine with an API, especially with access to the raw crawled content. Amazon used to do this was the Alexa web crawl data ( see http://www.readwriteweb.com/archives/alexa_turned_in.php ) but later withdrew that part of the service.

> Facebook in 2011 is small beans compared to the effect it could have on our species over the next hundred years.

If you replace Facebook with 'the internet', I'll go along with that. You're way too confident in this single company. Facebook is well positioned in the internet, but they're not everything and never will be.
They know they are overvalued and the stock will go down from there.

Why? Because the IPO ist gigantic, could be one of the biggest in history.

Google did start with just 1,9B. They were thinking the opposite. In order not to be ripped of, they tried to evaluate a base to raise money when needed.

The sad thing is, it will work. Facebook is overhyped in the media and the little guy believes it will be a Google story. It is still a very risky business and they can lose a lot of money.
Also it'd be nice if when I scroll down it didn't autoload the exact same set of messages that I've just read.
Mp4 to dvd
Since the movies and videos encoded in the MP4 format looks great, MP4 format is commonly used in various multimedia devices like iPod, iPhone and PlayStation Portable (PSP). However, sometimes you may want to watch MP4 videos or movies at home in a more easeful way, for example, to play it on your home DVD player. On this occasion, you need to burn MP4 to DVD. In fact, converting MP4 to DVD is very easy if you choose the right DVD burning software. For Mac users, here we highly recommend you use Aimersoft DVD Creator for Mac, a professional DVD converter to help you directly burn MP4 video and movies to DVD for playback on any home DVD players on Mac (Snow Leopard, Lion included). Besides MP4, it can also burn popular video formats, such as AVI, WMV, MOV, MKV,FLV, MPG, etc. to DVD.

Most likely, it's not a practical algorithm, in the sense that it would yield practical time improvement only for unfeasibly large matrices. It does not matter for theorists, though -- for them it's still important result.
Yeah if you amass your forces in the wrong place you will get slapped around like a cheap toy. Kursk salient.
Agree.

I can remember the issue of the EC's database directive from as far back as the early 1990's. It was one of the issues we studied.

At that time it seemed somewhat tenuous to apply it to what was happening on the nascent www.

For the most part it seemed no one was ostensibly collecting personal data and building sensitive databases of personal info. It was just a possibility we discussed.

Needless to say things have changed.
re: group theory approaches

This (http://www.siam.org/pdf/news/174.pdf) short, highly readable paper gives a high-level overview of the group-theoretic approach. Here are the key points, quoted from the paper:

* "What Cohn and Umans realized is that under certain conditions, matrix multiplication, too, can be embedded into the group algebra of a finite
group G, although the embedding is more complex and the group must be non-abelian to yield a nontrivial bound."

The conditions that must be satisfied are as follows:

* "...the group has three subgroups, H_1, H_2, H_3, with the property that whenever h_1 ∈ H_1, h_2 ∈ H_2, and h_3 ∈ H_3 with h_1 h_2 h_3 = 1, then h_1 = h_2 = h_3 = 1" (AKA the "triple-product property,") and

* "|H1||H2||H3| > Σd_i^3," where the d_i's are the dimensions of the square submatrices into which we decompose the original matrix. (AKA "beating the sum of cubes.")

The groups that have been found to have these properties are "wreath products of abelian groups with the symmetric group S_n."

You say your computer is "fast enough"? Imagine how little power your phone's processor would draw if it only needed the performance of, say, a PXA270 from 2005. What does your phone do that a seven year old PDA doesn't have the horsepower for? High def video and flash video, and that's about it. Software bloat is a pox upon computing technology. Something is very wrong when it takes a hundred times the computation to read the same email ten years later.
