CES 2009 Shrinks With Dwindling Economy

提交: January 7, 2009, 6:31pm CST 由 kdawson

Tags: [编辑]

nandemoari writes " Not long after we first heard murmurs Microsoft may be ready to lay off as much as 17 per cent of its workforce, the popular Consumer Electronics Show, held every year in Las Vegas, is rumored to be shrinking alongside the global economy. The Consumer Electronics Association, host of the CES, estimates that the numbers of both exhibitors and visitors will be down in 2009. The CEA expects about 130,000 people will attend this year, down 11,000 from last year. And about 2,700 exhibitors are expected to attend, down from 3,000 in 2008."

互联网过滤功难以补过

提交: January 7, 2009, 4:48pm CST 由 matrix

Tags: [编辑]

中国大多数人支持对网络审查和过滤，主要是认为这是一项正确的和有利于子女成长的工程。这种家长式的创造温房的想法究竟是对下一代有益还是过大于功？现任Google副总裁的互联网之父Vint Cerf在《真理与互联网》一文中认为，“教育我们的孩子们，懂得对他们所见所听深入地思考。这胜于任何的过滤，更能建立真理能稳站的基石。”....“真理是有力的溶剂，坚石高墙也可被它溶化。互联网是自由最有力的催化剂之一，可以把真理露出于愿意看到的人眼前，难怪有些政府和组织恐惧互联网和其揭发真相的能力。” 美国Wake Forest大学图书馆总监Lynn Sutton博士在《不准接入：互联网过滤如何影响高中学生的学习》书中引述了很多其他学术研究资料和结论，多数指出学校与家长与其主观过滤认为是不良的内容，不如教导学生自己严谨思考、分辨是非的能力，才一生受用。

We have also have run into some instances where it wasn't clear whose SD card was whose, and have also started to see a need for a storage mechanism. I have seen SD card 'wallets' and such, but have never seen anyone actually use one. So: How do you manage and keep track of your SD cards?"

在2004年的《宪法修正案》中，涉及平等的术语是“各民族一律平等”，和“中华人民共和国公民在法律面前一律平等”，所以如果我们看到不平等的规定时，是不是可以指责违宪？1月6日，出于应对当前经济不景气的局面，广东省检察院公布了帮助企业解困、促进企业发展的十条意见，其中明文规定：查办企业经营管理者和关键岗位工作人员的职务犯罪案件，检察机关要及时与主管部门或企业领导沟通，慎重选择办案时机，犯罪情节轻微的，酌情暂缓办理。对涉嫌犯罪的企业特别是目前仍在营运的困难企业，要慎用查封、扣押、冻结等措施；对企业法定代表人、生产经营负责人和技术业务骨干，涉嫌一般犯罪的，在确保刑事诉讼顺利进行的前提下，可不采用拘留、逮捕等措施。

Oprah Sued For Infringing "Touch and Feel" Patent

提交: January 6, 2009, 1:03pm CST 由 kdawson

Tags: [编辑]

I Don't Believe in Imaginary Property writes "Oprah Winfrey, or to be more precise, Oprah's Book Club, is being sued by the inventor/patent attorney Scott C. Harris for infringing upon his patent for 'Enhancing Touch and Feel on the Internet.' So Oprah's Book Club is now one of many people and entities being sued over this patent because they allow people to view part, but not all, of a book online before purchasing it. Mr. Harris also sued Google Books for infringing upon this patent. He actually was fired from his position as partner at Fish & Richardson for that, because Google is a client of that law firm and they had conflict of interest rules to uphold." It would be entertaining to see Oprah give very wide and mainstream publicity to the abuses enabled by our current patent system.

黑洞推动星系增长

提交: January 6, 2009, 1:00pm CST 由 matrix

Tags: [编辑]

天文学家可能解决了宇宙的鸡与蛋问题——谁第一个在早期宇宙中形成，是星系还是它们核心的超大质量黑洞？美国射电望远镜天文台的Chris Carilli在美国天文学会会议（American Astronomical Society）上称，“看起来是黑洞首先出现，证据是堆积（pile up）。”这一结论来自于一个国际团队对宇宙历史第一个10亿年的研究。加州大学的Dominik Riechers指出恒定的比率暗示黑洞和膨胀效应之间存在某些相互联系。 Max-Planck研究所的Fabian Walter表示，“我们现在终于有能力去观察创世大爆炸后第一个10亿年中出现的几个星系，测量它们的黑洞和膨胀质量。证据显示，在早期宇宙中，不变的膨胀比率无法为周围的质量所维持。年轻星系中的黑洞质量远大于附近的物质。”其隐含的意义上黑洞首先开始成长。

Obama Picks RIAA's Favorite Lawyer For Top DoJ Post

提交: January 6, 2009, 11:05am CST 由 kdawson

The Recording Industry of America's favorite courtroom lawyer, Tom Perrelli, who has sued individual file swappers in multiple federal courts, is President-elect Barack Obama's choice for the third in line at the Justice Department. CNet's Declam McCullagh explores the background of the man who won the RIAA's lucrative business for his DC law firm: "An article on his law firm's Web site says that Perrelli represented SoundExchange before the Copyright Royalty Board — and obtained a 250 percent increase in the royalty rate for music played over the Internet by companies like AOL and Yahoo," not to mention Pandora and Radio Paradise. NewYorkCountryLawyer adds, "Certainly this does not bode well for CowboyNeal's being appointed Copyright Czar."

Pandora 2.0 Adds Cover Flow and More [Featured IPhone Application]

提交: January 6, 2009, 9:39am CST 由 Gina Trapani

Tags: [编辑]

iPhone or iPod touch only: The already-good Pandora music recommendation engine app for the iPhone has gotten better with version 2.0, which adds Cover Flow view, artist and song info, and bookmark previews.

Take a look at some screenshots.

You'll need to sign into your free Pandora account to get started and see your stations. Make a new recommendation-driven station based on an artist; check out the suggest-as-you-tap search drop-down.

Once a song starts playing, you can give it the thumbs up or thumbs down (which informs Pandora's future recommendations), or tap the up arrow to get more options, like...

The ability to bookmark the song or artist, buy the track from iTunes, or share your station via email.

Turn your device to get into Cover Flow view, which works just like native iTunes (though I noticed a little flickering in the background album covers in my test).

Tap on the top right button to get artist details (shown here) and song details (shown below).

When you're wondering why Pandora included a recommendation in your station, the song info will tell you.

The Pandora 2.0 app is a free download for the iPhone or iPod touch only. Pandora (iTunes link) [via Webware]

Phishing Is a Minimum-Wage Job

Tags: [编辑]

rohitm918 writes "A study by Microsoft Research concludes that phishers make very little (PDF): '...low-skill jobs pay like low-skill jobs, whether the activity is legal or not.' They also find that the Gartner numbers that everyone quotes ($3.2B/year etc) are rubbish, off by a factor of 50. 'Even though it harvests "free money," phishing generates total revenue equal to the total costs incurred by the actors. Each participant earns, on average, only as much as he would have made in the opportunities he gave up elsewhere. As the total phishing effort increases the total phishing revenue declines: the harder individual phishers try the worse their collective situation gets. As a consequence, increasing effort is a sign of failure rather than of success.'"

城市如何伤害你的大脑

提交: January 6, 2009, 8:52am CST 由 matrix

Tags: [编辑]

城市是智力生活的引擎，现代艺术的发源地，没有城市就不会有莎士比亚，连爱因斯坦也从城市铁路中汲取了灵感。在城市生活是不容易的，它刺激了本富兰克林，也散播了霍乱或禽流感。但是现在新科学研究发现，城市环境还会损害我们的大脑功能。在拥挤的城市街道上走几分钟，大脑将无法储存记忆，自控能力也会突然下降。城市生活确实令人疲惫，研究暗示它还真让我们的思想变得迟钝。心理学家Marc Berman称，“大脑是一个有限制的机器，我们开始理解城市能越出那些限制。”考虑一下，你沿着繁忙的城市道路上行走，大脑里记忆着一些东西。你必须不停的改道躲避人群，持续不断的调整注意力令我们被不相干的事情分心。受约束的感知——我们告诉大脑关注什么——需要能量和努力。在人群稀少的自然环境下，我们就不要耗费太多能量去保持认知能力。密歇根大学的另一项研究发现，当人们花一个小时与自然亲密接触，他们的记忆性能和注意广度就能提升20%。心理学研究人员Marc Berman说，在曼哈顿中部有一个中央公园这不是偶然的，他们需要一个公园在那里。
新技术将彻底变革DNA测序

提交: January 6, 2009, 8:32am CST 由 matrix

一种新的纳米技术测序方法比当前的DNA测序快30000倍。根据发表在《科学》杂志上的一篇论文，Pacific BioSciences的一个研究小组利用纳米结构的由数千导波器（waveguide）排列的芯片，去隔离单个DNA分子和单个DNA聚合酶分子，碱基用不同颜色荧光粉标记。这种方法可以使读取长度，从20碱基(454序列)提高至大于4000碱基，达到99.3%的精确度。到目前为止，研究小组建造了一个包容3000 ZMWs(导波器)的芯片，公司希望能在2010年推向市场。到2013年，单一芯片上将能浓缩1百万ZMWs，芯片同时能观察DNA组装。Pacific创始人Stephen Turner估计，这样一个芯片将能在半小时内测序完人类的基因组，精确度99.999%，所需费用不到1000美元。相比较下，人类基因组的第一份草图花了十年功夫。

Windows 7 Beta Boasts Sub-30 Second Boot Time [Windows Startup Showdown]

提交: January 6, 2009, 8:11am CST 由 Gina Trapani

Tags: [编辑]

The Windows 7 beta offers a speedier startup than its predecessor: for me the beta boots to a fully functional desktop in under 30 seconds, faster than the preview or Vista.

On the same exact computer, where I'm triple-booting Vista, XP, and now the Windows 7 beta (build 7000), I ran a set of startup tests to pit the beta against the rest, using my previous measurements. Here's what I found.

table.comparison { border-width: 1px 1px 1px 1px; border-spacing: 2px; border-style: solid solid solid solid; border-color: gray gray gray gray; border-collapse: separate; background-color: white; } table.comparison th { text-align:center; border-width: 1px 1px 1px 1px; padding: 1px 1px 1px 1px; border-style: inset inset inset inset; border-color: gray gray gray gray; background-color: #cccccc; -moz-border-radius: 0px 0px 0px 0px; } table.comparison td { text-align:center; border-width: 1px 1px 1px 1px; padding: 1px 1px 1px 1px; border-style: inset inset inset inset; border-color: gray gray gray gray; background-color: white; -moz-border-radius: 0px 0px 0px 0px; } table.comparison td.has { background-color:#8EBB8E; } table.comparison td.label { font-weight:bold;text-align:center; }

The hardware: My test system has an Intel Core 2 Duo processor running at 3.16GHz with 4GB of RAM. Windows XP, Vista, and the Windows 7 beta build 7000 are all installed on the same, physical SATA hard drive (partitioned, of course).

The test: Since I'm triple-booting the three operating systems, I used a simple handheld timer to get my numbers, starting at the "Choose your operating system" screen (which comes after the BIOS startup) and ending at a fully functional desktop in my first set of tests, then the user login screen in my second. I timed each OS startup three times and averaged the results to account for my fat fingers.

Test Set 1: From Boot Choice to Fully-loaded User Desktop

For this test set, I created a non-Administrator user account with nothing in startup, and set Windows to automatically log into it on boot. These numbers start at the OS boot choice screen, and end at a fully-functional, user desktop. This isn't a true test of how long a desktop would render in real-world usage, because most people DO have programs in their startup. But these tests are to compare Windows version performance, not third-party software. That all said, the numbers:

Operating System	Average time to reach desktop
Windows 7 Ultimate (Beta, Build 7000, 32-bit)	28 seconds
Windows 7 Ultimate (Preview, Build 6801, PDC edition, 32-bit)	32 seconds
Windows Vista Ultimate (32-bit, SP1)	33 seconds
Windows XP Professional (SP3)	40 seconds

Here you can see that for the first time, Windows is offering a sub-30 second start time on pretty standard modern hardware, for the first time in at least a long time (if ever, I don't have a copy of Windows 95 or 3.1 to test). Of course, Microsoft claims that Vista boots in under 30 seconds already, but that's not the case on my tower; and only 23% of you say that your system boots in under 30 seconds. It should go without saying that this has a whole lot to do with exactly how beefy your hardware is.

Test Set 2: From Boot Choice to User Login Screen

This test measures the amount of time from the boot OS choice screen to the user login prompt only, hence the shorter times.

Operating System	Average time to reach login prompt
Windows 7 Ultimate (Beta, build 7000, 32-bit)	20 seconds
Windows 7 Ultimate (Preview, Build 6801, PDC edition, 32-bit)	23 seconds
Windows Vista Ultimate (32-bit, SP1)	24 seconds
Windows XP Professional (SP3)	29 seconds

The Results

As you can see, the Windows 7 beta took 4 seconds off the time it takes to render a usable desktop as compared to the Win7 Preview, which adds up to a 12-second difference from Windows XP. The beta shaved 3 seconds off the boot time to login prompt as compared to the preview build.

I can hear the comments already—"are we really talking about THREE SECONDS?" Yes, neither of these are earth-shattering improvements, but they are clear and consistent speed boosts, and hopefully they're a sign that things will get even faster since Windows 7 is still in beta.

Anyone out there move over to the Windows 7 beta full-time? What are your impressions? Post 'em up in the comments.
