    开心网的媒体作用

    最近,开心网上的好友转帖数量大量增加,感觉开心网已经成为一个媒体了。一方面是正统媒体入住开心网,发表新鲜的内容,至少《南方周末》、《新浪网》等都入住了;另外一方面,个人不断在转载网络上的各种信息,包括视频、音频、图片、笑话等等,基本上都是那种速效止疼丸,看时一笑,看过忘记。和新浪等新闻门户相比,开心网作为“体”的力度还有些不足,但作为“媒”力量却是很强大。其特点有:1.及时通知 2.和好友动态结合 3.内容经过好友筛选 4.和娱乐相结合 5.有原创 6. 交互性强,可以评论,投票等。

    这种形式比RSS+门户更有传播力,但是其内容的局限性,也注定其受众群是有限的。算是一条小尾巴,呵呵。下面是今天看到的转发,属于类似《手机报》最后的“IN语”风格,挺好玩。

    GoToMeeting:现在的网络会议系统很强劲

    这个系统是Citrix公司研发的在线网络会议系统,支持音频、视频、直接呼叫到PSTN电话,而且可以直接共享某个应用程序。这样将一次会议中需要的所有内容全部都包括了,很不错。对Webex应该有很强的杀伤力。

    纵贯线终点站 - 弄出些声音吧!

    周末和LP同去观摩了纵贯线的终点演唱会,这场演唱会之后,纵贯线乐队就会解散,4位高人就会分飞,这实在是一场很有纪念意义的终点,但是正如周华健最后说的那样,终点只不过是另外一个起点。

    到场较早,看到虽然不能说全部坐满,但是说有90%的座位有人恐怕不为过。一开场就是纵贯线的新歌,一下子全场的热情都被调动起来,看着大屏幕上出现的4张车票,很有一种回家的感觉。合唱之后,几位老大就按照罗大佑、张震岳、周华健和李宗盛的次序出场。几位牛人的高下、特点都展现无遗。罗大佑曲风有些愤青样,张震岳有些女气,周华健是个美声,而李宗盛真是太高。李宗盛选择了写给辛晓琪的感悟,但是完全按照自己的状态演绎,唱的很有些沧桑,有些回忆,还有些伤感。不得不佩服“小李”的功力,绝非寻常人可比。后来小李又客串鼓手,为张震岳爱的初体验伴奏,看来这些人都是全才。当中小李还邀请他的吉他作坊(位置在豆各庄)的手艺人共唱一曲,几位手艺人并不擅长吉他,变拿着各种趁手的物件打节拍,情景很是感人。

    最后四人又再次合唱,谢场后,观众反复要求,四位便“再次现身”,最后献上的是新歌亡命之徒,非常有激情,再次被感动…

    几个花絮:1. 前两排有个小伙子一直用摄像机偷录 2.前面有个30岁左右的老姑娘一直在疯狂地喊叫,非常High 3.看演出不能自带饮料真是TM太恶心了!

    华为超诺西成全球第二大移动网络设备厂商[zz]

    调研公司Dell'Oro周五发布的报告显示,华为今年第三季度超越诺基亚西门子,成为全球第二大移动网络设备制造商。
    报告显示,爱立信继续领跑全球移动网络设备市场,所占份额为32%。而华为从去年同期的11%提高到20%,跃居第二。诺基亚西门子排名第三,市场份额略低于华为。

    最近几年,在亚洲厂商的推动下,全球移动网络设备市场上争夺新业务的竞争日趋激烈。周五,爱立信刚刚完成收购北电CDMA和LTE资产交易,进一步巩固了其领导地位。
    上周,华为在挪威赢得了建设4G移动网络的合同,以取代爱立信和诺基亚西门子所建设的旧网络。该交易是迄今为止欧洲市场上规模最大的LTE交易,对于华为而言具有里程碑式意义。

    Windows7.0的兼容性还是有问题,切回XP

    终于有机会可以安装Windows7.0,挺激动地安装了一个,果然性能不错,启动和停止的速度都非常不错。界面效果、主题方案、色彩都非常酷,绝对比XP强很多。另外安全性也有很大的提高,不是什么程序都可以运行的,只有用户手工指定某程序以管理员身份运行才能够获得更高的权限,大体上就是以前NT4就有的RunAs,不过现在使用更为方便。在提示安装查毒软件的时候,选择了MS的MSE,之前在我的XP上运行很不稳定,在Win7上面倒是还不错。

    不过Win7有较大的兼容性问题,首先是界面变化很大,也没有和XP的兼容模式,经常找不到想要的功能,不过这一点时间长了还是可以适应的。更为要紧的有些软件安装不上,包括Cisco的VPN客户端,还有单位的OA,依赖于ActiveX,而在IE8上无法运行。

    某些同事为了解决这些问题,就在机器上面安装XP的虚拟机或者做成双启动的配置,感觉较为麻烦,最后还是放弃Win7,回到XP sp3。检查了一下,XP的服务时2008年4月截止的,但是OEM在低端PC的家用版本被延伸到2010年6月30日。

    也许升级到Win7是个迟早的事情,现在还是继续用XP吧。

    Google to acquire AdMob for $750 million[zz]

    转自CNET。估计是Admob在试图推进Android平台的移动广告时,增进了和Google的感情,然后被Google搞定,另外,据AdMob分析,Android平台的数据流量已经占据移动数据流量的17%,而iPhone是50%强。这些数据应该是来自于AdMob对发布网站的广告量统计。

    中国的移动运营商还在忙于打用户资费价格战的时候,却不知道后院已经失火!

    November 9, 2009 9:32 AM PST

    Google's back on the acquisition front, spending $750 million in stock Monday to acquire mobile display ad company AdMob.

    AdMob founder Omar Hamoui

    AdMob is perhaps best known for serving display ads on iPhones, but it also recently started a business unit focused on ads for Android phones. The start-up would appear to fit well into Google's advertising business model, giving Google a leg up in the still-small but fast-growing world of mobile advertising.

    "I'm excited because I believe this will be an important moment for everyone involved in producing, consuming, or monetizing engaging products on mobile," wrote AdMob founder and CEO Omar Hamoui in a blog post Monday. "The truth is that the mobile industry has had no shortage of creative energy, amazing products, and talented entrepreneurs. But until now, it has always felt like those of us involved in this space played second fiddle to our online brethren. I believe that time is over."

    AdMob was founded in 2006. The company runs its Mobile Advertising Network across thousands of Web sites, serving up ads from big names such as Ford and Coca-Cola. It also collects and publishes data on mobile trends gleaned from the traffic it manages.

    "Despite the tremendous growth in mobile usage and the substantial investment by many businesses in the space, the mobile Web is still in its early stages," wrote Google's Susan Wojcicki, vice president of product management, and Vic Gundotra, vice president of engineering, in Google's own blog post. "We believe that great mobile advertising products can encourage even more growth in the mobile ecosystem. That's what has us excited about this deal."

    Representatives from Google and AdMob are expected to talk about the deal in greater detail later on Monday. This is a friendly takeover, as both companies have already approved the deal, they said in a press release.

    It should come as no surprise that Google is back in a buying mood, after several weeks of talk from CEO Eric Schmidt and other company executives about Google's renewed prospects now that the company believes the worst of the advertising recession is past. At $750 million, the acquisition would rank as one of Google's largest deals, trailing DoubleClick at $3.1 billion and YouTube at $1.6 billion but edging out Postini's $625 million selling price.

    Google's stock was up 1.81 percent to $561 on news of the deal.

    上海电信e云的疑问

    上海电信和EMC属下的Decho合作,不久前推出了e云在线备份服务。上去仔细一看,原来就是Decho的Mozy服务。Mozy服务大约于2006年在国外开始运营,目前据说有几千万用户,我想其原因主要还是有个不错商务模式和技术平台吧,稍微对比下Mozy和e云,发现有些让人不解之处:

    1. 价格模式。Mozy和eyun都有2GB的免费空间。Mozy的业务是每月4.95$可以拥有无限量存储;eyun则是10GB空间每月15元,而300GB空间每月40元。

    2. eyun的客户端基本上就是Mozy客户端的汉化版本,不过eyun客户端的稳定性很差,在我的XP上面已经死机多次,还有几次蓝屏。不知道是汉化的问题,还是什么意外。鉴于此,估计服务器也是一样的设备。

    考虑到除去支付方式和币种不同外,实际上Mozy和eyun是有竞争关系的业务。也许Mozy由于某种政策原因无法进入中国才找电信落地(据说有EMC以产品入股方式参与eyun),而电信目前缺乏云存储技术,欲用eyun打开局面,取得竞争优势。两下就做成了生意:-)

    Sina App Engine/SAE有些山寨

    bannerSina冷不丁搞出来一个SAE还是有些让人一惊的感觉,这个SAE是sina在最近几个月中研发完成的,目前处于Alpha状态,从其blog看,应该仅供内部开发人员测试使用,一共发布200个账号。正式些的版本估计要等到明年年初。

    SAE不是基于Python、Java或者Ruby,而是选择了目前最为流行的Web脚本PHP - 也是我较为熟悉的语言,心中也是不是冒出要搞个类似系统的念头。还是sina首先做了出来。就我个人而言,为什么GAE没有选择PHP这个如此流行的玩意,而是选择了Python和Java,可能主要原因在于PHP的管理能力不够,或者说想让PHP变得可管理较为困难一些。不知道SAE在PHP应用隔离方面是否有什么好的解决方案。

    SAE目前提供了一些开源的组件来支撑应用开发服务,如下(http://wiki.sae.sina.com.cn/doku.php):

  • PHP5 Runtime运行环境 - - - - 基于PHP 5.3.0内核

  • 支持读写分离的分布式数据库服务 - - - - 基于Mysql数据库

  • 分布式文件存储服务 - - - - 基于分布式文件系统

  • 基于Memcache协议的分布式缓存服务 - - - - 基于集群memcache系统

  • URLFetch远程数据抓取服务 - - - - 基于分布式proxy服务

  • Cronjob定时任务 - - - - 基于分布式定时器服务

  • SPP图片处理服务 - - - - 基于分布式高CPU计算服务

  • 其中分布式文件系统、SPP的详情并不为人知晓。MySQL则可能采用了Sharding技术,但是能够存储多大的容量,并没有看到SAE中有明确说明。另外,从这些服务中,我们并没有看到计费服务和用户绑定,这可能就是SAE尚是Alpha版本的原因。

    希望SAE能做的更好,挑战一下GAE:-)

    IBM DB2 PureScale挑战Oracle Exadata

    ibm-pure-scale-arch2IBM在10月10日推出PureScale技术,号称能够挑战Oracle Exadata。从其白皮书看,PureScale是DB2基础上的一种改进技术,主要改进是在于采用了一种分布式缓存技术PowerHA,同时这也是一种集中式锁管理系统。PowerHA采用InfiniBand高速网络来连接所有节点和存储。当有读写冲突的时候,PowerHA可以及时通知相应的节点,响应时间在15毫秒,这样会减少进程的等待时间,提高CPU利用率。除此以外,PureScale并没有更多的信息,因此总的来看,PureScale还是在DB2这种貌似sharenothing,其实sharesomething的架构上作的局部优化,和Exadata的变化相比还是很有限的。如果没有TPCC的结果,还是很难让人信服这可以超越Oracle在事务处理方面的能力。

    但是Oracle Exadata在此前的一年销售似乎并不怎么好,这次TPCC测试的结果应该会对Exadata的销售有不小的帮助。

    NSN may cut nearly 6,000 jobs[zz]

    摘要:NSN这次裁员8%左右,从64000员工中裁员5760人。并重组为三个BU:解决方案;网络系统和全球服务,于明年1月1日生效.

    想想某嗅嗅真是高明,早早离开NSN跑到Ericsson去了 :-)

    Nokia Siemens Networks, reeling from weaker sales and declining market share, said it may cut as many as 5,760 jobs as part of a broad restructuring and cost-cutting program.  The program includes reducing the number of its business units from five to three and lowering its procurement costs.

    The company said it aims to reduce expenses by $733 million annually by the end of 2011 compared with the end of 2009. Additionally, the cuts in procurement costs will be "substantially larger" than other cuts, and are being made to "meet ongoing customer requirements for competitive pricing." That could bring the total cost cuts to nearly $1.46 billion. Nokia Siemens said it may cut 7 percent to 9 percent of its 64,000 employees, and that some countries may see job losses higher or lower than that range.

    Just as Nokia reshuffled its front office and reorganized its handset business in the wake of its $834 million net loss in the third quarter, it now appears that Nokia Siemens--Nokia's joint venture with Germany's Siemens--is restructuring after a period of weak performance. In the third quarter, NSN's sales slumped 21 percent to $4.16 billion. The company had an operating loss of $1.64 billion in the quarter, compared with an operating loss of $1.48 million in the year-ago quarter. The company's market share also is expected to decline more in 2009 than Nokia and Nokia Siemens had previously anticipated.

    In addition to the cost cuts, Nokia Siemens said it would streamline its business structure, actions scheduled to go into effect Jan. 1. The company plans to reorganize into three business units: business solutions, network systems and global services. Jürgen Walter, currently head of the company's converged core unit, will run business solutions; Marc Rouanne, currently head of the vendor's radio access unit, will run the network systems business; and Ashish Chowdhary, currently the company's services chief, will run the global services business.

    NSN also said it is open to making acquisitions when "assets are available and the associated purchase price of those assets provides the appropriate value."

    “洲际导弹”语录 [zz]

          新华网消息称,2009年10月31日下午,十一届全国人大常委会第十一次会议表决通过,免去周济的教育部部长职务,任命袁贵仁为教育部部长。另据媒体报道,11月1日下午,中共中国工程院党组书记、院长徐匡迪主持召开了中国工程院主席团会议,中共中央组织部副部长李建华在会上宣布了中央关于周济任中国工程院党组副书记的决定。

          对周济被免职的消息,网友中“欢呼叫好”者占了较大比例。南方都市报报道,教育界人士许锡良、信孚教育集团董事长信力健在博客上对周济任内的诸多政策提出了不同看法,言辞间不乏火药味,如直称周济为“洲际导弹”。信力健直指周济“没弄懂的问题”:“教育的本质是平等及自主权”,“最大的政绩败笔”是“制定高标准,封杀民办学校”,“对教育的短视体现”为“倡导精英教育,忽视平民教育”。自称“一辈子都在和教育打交道”的周济,是中国“文革”前的最后一批大学生,毕业于清华大学,1980年赴美留学,获纽约州立大学博士学位。 1984年学成回国后,周济进入华中理工大学任教,13年后出任该校校长,随后当选为中国工程院院士。1999年至2002年,他先后担任湖北省委常委、省科技厅厅长、武汉市委副书记、副市长、市长等职。2002年,周济被任命为教育部副部长,翌年接替陈至立出任教育部部长。

                             —— 2007年,针对网友提出当前就业形势日趋严峻是高校扩招的结果,周济回应

    “ 网络对青年学生的影响非常深刻,这是我们面临的新情况。我们发现,大部分同学获取信息的主要途径是网络……很多持正确意见的人不一定发表意见,倒是喜欢发牢骚的人发表意见。另外,有国外组织散布各式各样信息。同学们不仅看了,还信,所以,这给我们提出了新问题……”

    “短短几年,我国已经进入高等教育大众化阶段,这是了不起的成就。除了教育投入之外,我们以前制定的目标都达到了。”

                                                             ——2005年,周济表示,扩招未导致高等教育质量滑坡

    “我国的研究生数量比印度的还要少,而且,我们对研究生的考试选拔比国外的许多地方还严格,所以,根本不存在所谓研究生大跃进的问题。”

    Wireless in the third quarter of 2009[zz]

    看到一则部分运营商和设备商本季度营收情况报告,看到运营商倒是有些盈利,设备商Ericsson、Nokia、ALU的收入都下降,韩系终端厂商的收入上升。

    Oct. 15
    Nokia

    Nokia reported a $834 million loss in the third quarter, the handset maker's first quarterly net loss since it started reporting quarterly in 1996. The results are largely due to a writedown Nokia was forced to take on its Nokia Siemens Networks joint venture, though flagging smartphones sales also contributed to the dramatic decline.
    Oct. 16
    Sony Ericsson
    Sony Ericsson's troubles continued in the third quarter, with the struggling handset maker posting its fifth straight quarterly loss and showing weakness in several key metrics. The joint venture between Japan's Sony and Sweden's Ericsson posted a $245 million net loss in the quarter, less than analysts had anticipated but wider than the $37.7 million loss it had in the year-ago period.
    Oct. 19
    Apple
    Apple shipped 7.4 million iPhones in its fiscal fourth quarter, the most it has ever sold, besting the 6.9 million it shipped in the quarter following the launch of the iPhone 3G last year. The iPhone figures helped anchor Apple's most profitable quarter ever.
    Oct. 21
    LG
    LG Electronics posted strong company-wide results in the third quarter, partially driven by increased handset shipments--but the company's profit margins suffered. Further, LG reported a decline in cell phone shipments in North America and South Korea
    Oct. 22
    AT&T

    Thanks to the iPhone 3GS, AT&T Mobility once again added a record number of subscribers in the third quarter of 2009. The company said that it added 2 million wireless subscribers in the quarter, bringing its total base to 81.6 million. In addition, AT&T said it activated 3.2 million iPhones, the company's largest amount to date, with nearly 40 percent of those activations from customers that were new to AT&T.
    Ericsson
    Ericsson's net profit in the third quarter fell 71 percent, as a constellation of factors--declining sales, losses at Sony Ericsson, intense competition and restructuring--contributed to the Swedish vendor's weak performance.
    Oct. 26
    Verizon
    Verizon Wireless maintained a strong third quarter with revenues of $15.8 billion, up 24.4 percent year-over-year, and services revenues of $13.5 billion, up 23.7 percent year-over-year. The company added 1.2 million net wireless customers in the quarter for a total of 89 million subscribers.
    Oct. 29
    Sprint Nextel
    Although the bleeding slowed, Sprint Nextel reported continued postpaid subscriber losses in the third quarter. The company's prepaid business had another strong quarter, but Sprint's net loss widened and it saw a drop in revenue in the quarter.
    Motorola
    Motorola appears to be making good on its promise to turn itself around. The struggling equipment maker surprised investors today by posting a third quarter profit of $12 million, way up from the $397 million loss it recorded in the third quarter of 2008. However, the company's third quarter sales were $5.45 billion, down from $7.48 billion in third-quarter 2008.
    Oct. 30
    Samsung
    Samsung Electronics posted its highest quarterly profit ever in the third quarter, partly due to its success in handsets--the global No. 2 handset manufacturer shipped a record 60.2 million phones in the quarter.
    Alcatel-Lucent
    Alcatel-Lucent reported a wider net lost in the second quarter on weaker sales. However, the company restated its previous forecast of nearing break even for the year on an adjusted operating level. 详细信息如下


    Alcatel-Lucent reported a wider net lost in the second quarter on weaker sales. However, the company restated its previous forecast of nearing break even for the year on an adjusted operating level.

    The infrastructure vendor had a net loss of around $270 million, wider than its net loss of $59.2 million in the year-ago period. Revenue fell 9.3 percent to to $5.46 billion. The company's carrier unit saw a double-digit decline in revenue.

    Alcatel-Lucent's stock remained relatively unchanged on the news, sitting at around $4.17 per share in early morning trading.

    Despite the weak performance, the company maintained its outlook on nearing break even by the end of the year. The company is in the midst of a $1.1 billion cost-cutting program, and Alcatel-Lucent CEO Ben Verwaayen said the vendor had achieved 80 percent of the cuts so far this year. He said he expects the telecom sector to return to single-digit growth in 2010.

    It appears Alcatel-Lucent won't be alone in its third quarter troubles. Already this month rival Ericsson reported a 71 percent decline in profit.

    • Revenues of Euro 3.687 billion, down 9.3% year-over-year and 5.6% sequentially

    • Adjusted2 gross profit of Euro 1.232 billion or 33.4% of revenues

    • Adjusted2 operating income1 of Euro (11) million or (0.3)% of revenues

    • Reported net loss (group share) of Euro (182) million or Euro (0.08) per share

    • Operating cash flow3 of Euro 739 million

    • Net (debt)/cash of Euro 592 million as of September 30, 2009

    • Full-year 2009 guidance to be around break-even at the adjusted2 operating income1 level reiterated
