From bad to worse: latest figures on global greenhouse gas emissions. “The 38 countries that pledged to restrain their emissions of climate change–inducing greenhouse gases, most notably carbon dioxide are failing... most industrialized European nations as well as China and the U.S. (which have not agreed to any emissions' reductions) have been spewing more carbon dioxide since 1990—up in total some 403 million metric tons of CO2e from 2000 levels. The UNFCCC cautions that emissions ...

Oh hey, welcome to 500GB laptop drive announcement party Toshiba. Shame you had to come dressed in the same 9.5-mm slab, 2.5-inch 3Gbps SATA interface, 1.4 watt idle power draw, 5,400rpm spin, and 25dB hum as everyone else in the room. Pretty, but still embarrassing. No full-disk, hardware encryption but at least you can take comfort at besting some (but not all) of your competition by actually shipping your drive in December.[Via Impress]Filed under: StorageToshiba's ...

Toshiba vient-il d’inventer l’ultime tout-en-un ? En tout cas, le G450 est plutôt impressionnant : à la fois téléphone, baladeur et modem portable pour son notebook ! Techniquement, l’objet est un modem 3G (UMTS 2100 Mhz, HSDPA 7,2 Mbps), mais également GSM et GPRS/Edge. Côté baladeur, il n’offre que 160 Mo de stockage, ce qui est aujourd’hui beaucoup trop juste. Pour le reste, cet amusant bâtonnet dispose d’un écran Oled (96×39), un port mini USB ...

It has always struck me as a little contradictory that while one of the government's primary goals is to build citizen awareness of various services, issues, initiatives and opportunities, at the same time many government communications and publications (than need to be) are protected under rigid copyright disclaimers.I've even seen situations where government agencies require that organisations formally request permission before linking to their websites, although this is almost totally unenforceable and contrary to one ...

Yesterday Gartner reported that 85% of companies surveyed in May and June acknowledged they are using open source software (OSS), and the other 15% plan to start in the next 12 months. OSS has clearly gone mainstream. The top reason cited was lower total cost of ownership. I suspect that OSS adoption will broaden and deepen quickly if the economic slowdown persists. But as companies gain experience, other compelling reasons for using OSS will become ...

No período em que estive em São Paulo, pude conversar mais com Ariel e Joana. Em um desses papos surgiu o insight de que vivemos em um momento que toda comunicação quer ser viral. Cada vez mais me convenço disso, mas ao mesmo tempo me pergunto se isso é tão inédito assim. O tal do “viral” Sabemos que um viral se caracteriza pela propagação de uma mensagem através do boca-a-boca. A mensagem interessa tanto a ...

大家都知道，三角形具有稳定性。如果你把三根木条钉成一个三角形，则这几根木条是不能活动的。这是因为，根据三角形的SSS全等判定法则，两个三角形的三边长对应相等，则这两个三角形一定全等。但四边形就不是了，用四根一样长的木条钉成一个正方形，握着相对的两个角往两边一拉，正方形就变成菱形了。不知道大家想过没有，类比到三维空间中，多面体的稳定性又是怎样的呢？ Cauchy定理指出，如果两个凸多面体对应的面全等，那么这两个多面体全等。这告诉我们，任何一个凸多面体一定都是不可活动的。在Cauchy定理中，“凸多面体”这一条件是必需的。如果允许凹的多面体存在，对应面相等但整个多面体不全等的形状可以很轻易地构造出来。例如，想象立方体的某个面中心有一个小金字塔，这个金字塔既可以是向外凸的（就像表面上的一根刺），也可以是向内凹的（表面上的一个坑）；这是两个截然不同的多面体，但它们的对应面都是相等的。不过，这与我们的稳定性并没有关系，因为它并不是做连续的变形，而是直接一下就“跳”过来了。 很长一段时间，人们曾经猜想，不存在可以做出连续变形且保持所有面不变的“可活动多面体”(Flexible Polyhedron)。1978年，Connelly找到了第一个反例。他给出了一个由18个面组成的可活动多面体。 Proofs from THE BOOK的第12章给出了Cauchy定理的一个非常精巧的证明，并在这一章末尾给出了一个更加简单的可活动多面体（上图），它是由Klaus Steffen构造出来的，只含有14个面和9个顶点，现在已经证明是“最简单”的可活动多面体。如果你按图中所标注的比例裁剪一张展开图，拼接成一个多面体的话，你可以捏着它的一条棱拽来拽去的玩。 你猜怎么着？我还就真做了一个！我把这个pdf文件打印在了一张稍微硬一点的纸上，然后按图示粘贴成了一个可活动的多面体。标了黑线的地方应该往外折，蓝线则应该往内折。做好后捏在手里玩了一下，嘿，还真他妈的可以动！
