There are 8 triangle pieces and 8 kite-shaped pieces. The triangles are 30 degrees and the kites are 60, so two triangles can take the place of a kite. The middle layer has two opposing trapezoids. Because of the shapes, it can twist horizontally, vertically, and diagonally along any triangle or kite line. It’s basically a Rubik’s cube on heroine.

Most have already seen this, if not, it is a very accurate observation.
If you want to evaluate the “evil” quotient of any company’s strategy/behavior, consider how you’d feel about it if it were Microsoft in the driver seat.
Robert McLaws of Windows-Now.com fame reminded me of my “Is Google evil?” litmus test in his post, “Google: The New Big Brother.” As McLaws paraphrased it: “When looking at any new Google venture, swap out the word ‘Google” with ‘Microsoft’ and ask yourself if you’re still OK with what’s happening.” link
Whether you code in Ruby or not, you have to check out this book. It was written by _Why (identity unknown), and is unusual among programming books in that it includes quite a lot of strange humor and narrative side tracks that don’t necessarily have anything to do with the topic.
Back in the 1990s Bill Gates said the company that would eventually beat Microsoft probably had yet to be founded - some people believe that company is Google. But what about Google itself, who will kill Google? An interesting analysis of who is most likely to form “the next big thing”.
Good article… I don’t know if I buy all of it, but good!
Wants you to buy gas from Citgo stations. Why?
1. To protest president Bush. (Because it was his administration that supported a military coup in 2002)
2. It helps the communist Hugo Chavez feed the poor of his country.
FACT: If Hugo Chavez really wanted to end poverty in Venezuela, it would have been done already. And if socialism really helps the impoverished why were there breadlines in the former USSR as of 25 years ago. Hello, we are talking about bread here. The reason for no bread, no one wanted to make it for nothing. Socialism = no incentive to work, no incentive to strive for something better. Venezuela is simply next in line.
And, Socialism itself is by no means a monolithic movement; there are important points of disagreement between its several branches. Therefore, some of the criticisms presented below may not apply to all forms of socialism (for example, many of the economic criticisms are directed at a Soviet-style planned economy, while some proposed socialisms advocate different methods of economic planning, and others reject planned economics altogether). Critics argue that socialist policies reduce work incentives and efficiency through the elimination of buying and selling of means of production, eliminating the profit and loss mechanism, lacking a free price system and relying on central planning. They also argue that socialism stagnates technology. They further argue implementing socialist policies reduces prosperity of the populace. Some socialists reply in kind, with the counter-argument that socialism can increase efficiency and economic growth better than capitalism. Other socialists argue that a certain degree of efficiency can and should be sacrificed for the sake of economic equality or other social goals. link
In reality it’s all about “Hugo” and his pockets. The only beneficial Marxist was Marx himself (And he is long dead). Everyone thereafter, quite simply see the individual benefit in total governmental control and decree. Indeed the majority of all politicians are corrupt or have corruptive tendency. But I prefer democratic capitalistic corruption over ultimate power! And so should you.
“Protesters say President Hugo Chavez is limiting freedom of expression and taking the country down the path of dictatorship.”
“But the president maintains he has the right to silence a channel that he says actively tries to undermine his government.” Ah ok, even better that it is the only one. link
“So get your gas at Citgo. And help fuel a democratic revolution in Venezuela.”
Jeff Cohen is an author and media critic (www.jeffcohen.org)
This guy is real thick! His quote “fuel democratic revolution”, Are you kidding me. Hugo Chavez started taking land from private owners and just shut down the only television station that was contridictory to his REGIME!:/p>
And for the GPL’rs, here is your leader. Stallman on his personal site agrees with psycho Jeff Cohen, of course no one should be surprised.
The open-source community is very vocal about software patents. Sun owns lots of them. Isn’t that a contradiction for Sun to claim to be an open-source community member yet own software patents?
Ah, ya, ok, whatever Sun! I read the article four times and I still don’t get where they are coming from on this. But like most large companies that have thousands of patents and are an avid open-source community member, i.e., IBM. They want “YOU” to believe in the movement (OS, GPL etc). Why, because they benefit by using that Open Source for relatively low cost; while integrated with their own solutions for which they make millions upon millions of dollars. Who benefits from Open Source again? (monetarily speaking)

Your free lunch will soon be over. What can you do about it? What are you doing about it? In this article, I
’ll describe the changing face of hardware, why it suddenly does matter to software, and how specifically the concurrency revolution matters to you and is going to change the way you will likely be writing software in the future.
This podcast was recorded on the floor RailsConf2007 in Portland, Oregon. Scott Hanselman talks to Martin Fowler of Thoughtworks and David Heinemeier Hansson of 37signals and talk about beauty, making developers happy, the death (or life) of HTML. Will you be still using HTML in 10 years?
Universality this framework has one disadvantage. It is difficult to study it, since it has a large number of facilities. Even author of this software was being frequently discouraged. The best method of studying or using this soft is handling a lot of samples of its applications. This paper contains samples devoted to automatic control and processing of signals.
This article is written based on request from readers for concrete examples of the Universal Framework for Science and Engineering. We shall consider a class of scientific problems related to regression. I’ll show how this framework solves problems in astronomy, control systems, and navigation.
I am engaged in lots of branches of science and engineering. These branches include Astronomy, Radio-physics, Electronics, Industrial control systems, Space navigation etc. The education at the VDI Training Center has given me an idea of merging all my development to a single framework. The result of this work has already exceeded all optimistic expectations. A lot of competitive science and engineering problems could now be solved at once. A set of projects with the same core has been created. Two of them are accessible for public use. The first one is devoted to astronomy, the second one operates with the math Theory of Categories. The idea seems to me very universal, and I have decided to publish it.
The BBC’s Mark Ward has rarely had anything good to say about Microsoft, but he argues that Silverlight could be a significant product, well beyond a simple “flash killer”. Ah yes, it’s about time he saw the light!
When Microsoft Corp. CEO Steve Ballmer speaks, dissecting his words can sometimes take a while. The brash but successful CEO sometimes says things that demonstrate arrogance or a misunderstanding of certain markets, but generally he’s right on target. Ballmer recently stated that Microsoft’s mantra is “staying ahead”…
Parallel programming uses threads to enable multiple operations to proceed simultaneously. In Part 1 we will examine how to do multitasking in a parallel programming applications by breaking up programming tasks into chunks that are suitable for threading. I am impressed, very good read!
Programming Microsoft Composite UI Application Block and Smart Client Software Factory Book on the Way. I am hoping that this book provides a good path through the documentation and that it settles some of the contradictions found in it.
Really great blogging site dedicated to an enormous scientific content directory
Science is driving our global conversation unlike ever before.
From climate change to intelligent design, HIV/AIDS to stem cells, science education to space exploration, science is figuring prominently in our discussions of politics, religion, philosophy, business and the arts. New insights and discoveries in neuroscience, theoretical physics and genetics are revolutionizing our understanding of who are are, where we come from and where we’re heading. ScienceBlogs is a portal to this global dialogue, a digital science salon featuring the leading bloggers from a wide array of scientific disciplines. Our mission is to build a community of like-minded individuals who are passionate about science and its place in our culture, and give them a place to meet.
We believe in providing our bloggers with the freedom to exercise their own editorial and creative instincts. We do not edit their work and we do not tell them what to write about. We have selected our 40+ bloggers based on their originality, insight, talent, and dedication and how we think they would contribute to the discussion at ScienceBlogs. Our role, as we see it, is to create and continue to improve this forum for discussion, and to ensure that the rich dialogue that takes place at ScienceBlogs resonates outside the blogosphere.
ScienceBlogs is very much an experiment in science communication, and being first also means being first to encounter unforeseen obstacles. We are learning as we go (and as goes the blogosphere) and appreciate your understanding and patience.
ScienceBlogs was created by Seed Media Group. Our mission is to change the way the world sees science — from a separate island on the periphery of culture to the central driver of our times. We believe that science literacy is necessary for all modern societies. At a time when public interest in science is high but public understanding of science remains weak, we have set out to create media and entertainment products to improve science literacy and to advance our science culture. To learn more about what we do and why we do it, please visit seedmediagroup.com.
