钱五哥の共享空间最好退休前就有过到烦的假期 November 17 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。 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。 from cnbeta,记录一下 November 16 遭遇乌鸦轰炸晚上从Hadoop In China大会回家,在家门口的路上,忽然前挡风玻璃上面落上两枚乌鸦bb炸弹,真是寒。停车后,回头一看,不知道为什么今夕园某塔楼上方有大量的乌鸦在盘旋,到底是什么原因? November 15 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 (Credit: AdMob) 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 $561 on news of the deal. November 10 上海电信e云的疑问上海电信和EMC属下的Decho合作,不久前推出了e云在线备份服务。上去仔细一看,原来就是Decho的Mozy服务。Mozy服务大约于2006年在国外开始运营,目前据说有几千万用户,我想其原因主要还是有个不错商务模式和技术平台吧,稍微对比下Mozy和e云,发现有些让人不解之处: 1. 价格模式。Mozy和eyun都有2GB的免费空间。Mozy的业务是每月4.95$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:-) 相关信息: November 09 Sina App Engine/SAE有些山寨
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:-) 相关链接: November 08 IBM DB2 PureScale挑战Oracle Exadata
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。 更多信息: 1. http://www-01.ibm.com/software/data/db2/9/editions-features-purescale.html November 04 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." November 02 “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。
“恢复高考30年的历史可以证明,高考为我国选拔人才作出了很大贡献。现在高考在我国还是行得通的,是一个非常公平的制度。” ——2007年,周济谈高考制度 “我认为现在就业问题不是因为扩招引起的,因为这些孩子迟早都要就业,只是读完大学就业,还是不读大学就业的问题。” —— 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……” —— 2004年,周济在教育部的一次座谈会上 “首先你这个问题提的不对,我们没有把BBS的论坛关掉,而是加强了管理。” ——2005年,高校bbs采取实名制并禁止校外人员登录发言,周济答路透社记者问 “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。” ——2004年,周济谈研究生考试选拔制度 来源:南方周末网 November 01 2009年11月1日,北京大雪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 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 $1.1 billion cost-cutting program, and Alcatel-Lucent CEO Ben Verwaayen said the vendor had achieved 80 percent of the cuts so far this year. He said he expects the telecom sector to return to single-digit growth in 2010. It appears Alcatel-Lucent won't be alone in its third quarter troubles. Already this month rival Ericsson reported a 71 percent decline in profit. • Revenues of Euro 3.687 billion, down 9.3% year-over-year and 5.6% sequentially • Adjusted2 gross profit of Euro 1.232 billion or 33.4% of revenues • Adjusted2 operating income1 of Euro (11) million or (0.3)% of revenues • Reported net loss (group share) of Euro (182) million or Euro (0.08) per share • Operating cash flow3 of Euro 739 million • Net (debt)/cash of Euro 592 million as of September 30, 2009 • Full-year 2009 guidance to be around break-even at the adjusted2 operating income1 level reiterated 相关信息: October 30 Bing和Hadoop的关系今天听说Bing中和Hadoop有关系,到底是什么关系呢?搜索了一下,原来Powerset是关键,而Powerset被微软于2008年以100M$收购,现在已经是Bing的一个部门。在开源世界,Powerset是HBase的开发者,难道这次HBase就此落地? 其实并非如此,用Powerset的总经理的话说Powerset对Bing的贡献即微妙又显著。微妙之处说不明白,显著之处是Powerset的语义搜索在Bing得以实施,可以在左侧的“Reference”栏目找到。尝试了一下,中文版本的Bing似乎没有这个能力。Powerset在语义搜索中使用Hadoop生成索引,于是Hadoop和Bing就这么曲曲折折地建立了关系。 至于说Bing的其他网页索引是否使用Hadoop技术,网页是否使用HBase存储则不得而知了。 相关信息: October 29 IT互联网薪酬大曝光[zz]http://www.newsmth.net/bbstcon.php?board=WorkLife&gid=4089415 互联网: 软件: 硬件: 网络: October 26 Oracle Exadata V2的TPCC测试结果关于Sun Oracle Database Machine V2,Oracle在10月12日提交了TPCC的测试结果,一分钟执行的TPC-C事务可以达到7,717,511 ,这比之前排名第一的IBM DB2的6,085,166 高出25%多。而价格却要更低。仔细查看了一下配置,用于测试的DBMV2并不是DBMV2的标准配置: 标准配置: TPCC配置: 看来TPCC的结果也是仅供参考,不仅仅针对系统做优化,配置也很大不同,服务器也从x86变成SPARC 相关资料: October 23 近日疯传的两个段子[zz]1 、 检讨书
October 21 谣传:Google to make its own Android phone又来了,不知道是不是空穴来风 Google is planning to release its own branded, unlocked, Android-based phone this year, according to a report in TheStreet.com. The move would mark a major break with the system Google has set up to grow the reach of its Android platform. The report, which cited Northeast Securities analyst Ashok Kumar, said the company will work directly with retailers on the phone, and not wireless carriers. The report said that Kumar talked with Google's design partners about the plans and the phone is said to be using Qualcomm chips but no hardware partner was named. If the plan becames a reality, it would represent in a dramatic shift in Google's Android strategy. The company to date has offered its Android software for free to handset makers to build their own devices and, in some cases, user interfaces. In the United States, Cellular South, Sprint Nextel, T-Mobile USA and Verizon Wireless have all openly declared their support for the platform, with handset makers ranging from Motorola to HTC to Samsung supplying the hardware. For Google to change course and offer its own device would essentially pit the company against supporters of its own platform. Indeed, Palm encountered problems with just such a strategy during its PDA days, and in 2003 divided into two separate companies--Palm for hardware and PalmSource for the OS--to address Palm OS licensees' competition concerns. Interestingly, the GPhone rumor is not new. In the early days of Android, rumors pointed to the possibility of a Google-branded phone. A Google spokeswoman did not immediately respond to a request for comment. 子弹击中人体后真实的威力有多大?[图]感谢小胡转载,真实的战争是很残酷的,不是那些粗制滥造的警匪片和战争片能说明白的,可以看看《黑鹰降落》和《拯救大兵瑞恩》里面的场景,感觉比较真实。 新配了图片重新发布文章。 1:胳膊中枪,还能开枪。

Google Doc最近微软推出了一个Microsoft Security Essentials,是个类似360的木马检测软件,运行在Windows平台,是个免费软件,这种免费策略和Google Docs、Maps、Earth一样,都是用来曾加用户粘性的。从开发难度上看,MSE比GoogleDoc这类在线应用似乎要更复杂一些,至少有较多的算法;但是在运维方面则简单一些,不必实时对大量用户的操作给出反应,同时也不必维护大量的节点。 谁能获得成功,即要黏住用户,免费工具是用户的最爱,因此谁家的工具多且实用,谁就可能笑到最后。 可惜MSE虽然自称说短短几周就保护了几百万用户,确实也在我机器上面发现了一个有问题的玩意 – c:\windows\system32\dmserveresl.dll (看上去这个软件是MS自己提供的,删了再说吧),但是MSE却在检查到最后时挂掉了,出现蓝屏。然后用以前的Microsoft Malicious Software Remover尝试了一下,结果也是一样,估计是访问了被锁定的文件 - 也可能是干不过病毒吧。最后只好删除MSE,看来MSE没有黏住我,呵呵 相关信息: |
