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 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。

    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

    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。

    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:

    image  


    Fast X86 CPUs processors
    Includes Sun Fire X4170 Database servers and Sun Fire X4275 Storage servers exclusively optimized for Oracle Exadata V2
    Sun FlashFire Technology for High Speed Transaction Processing
    Sun Datacenter InfiniBand Switch 36 and Sun Rack II

    TPCC配置:
    Database Server: UltraSPARC T2 Plus 1.6GHz 
    Storage Server:X4275, FC, SAN

    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

    近日疯传的两个段子[zz]

    1 、 检讨书
    我刚到纪委工作就犯了严重错误:前天我接到通知说中央电视台记者要来采访我市廉政先进典型,领导要我通知几个好局长来。
    为了赶快下班,所以我通知各单位时说的比较简单:“请你们局长明天到纪委来一趟。”
    没想到国土局长接到通知后大小便失禁,心脏病突发,不醒人事。财政局长自首了。交通局长当晚就失踪,据说已逃往加拿大。工商局长连夜杀死情妇,他以为她出卖了他。卫生局长服毒自杀,还留下检举别人的名单。
    这惨痛的一切都是我工作方法简单造成的,我痛定思痛,深感内疚,特作检讨!

    2 、密码
    深圳市市长许宗衡被双规,家中一大保险柜久不能开。一识货中纪委官员说:此乃声控锁,密码多用八个字。
    于是办案人员召集大家轮流猜试  : “人不为己,天诛地灭”; “芝麻开门,芝麻开门”; “上天保佑,升官发财”; “八仙过海,各显神通”; “人为财死,鸟为食亡”; ……但均不灵!
    无奈,押许市长至此。他清清嗓子,用浓重的湖南湘潭话正色道:“清正廉洁,执政为民!”柜门应声而开,满柜金银珠宝惊呆众人!

    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.

    四两拨千斤!

    人人都想做四两的事情,那么千斤重担谁来挑呢?

                                       - 有感于某次聚会聊天

    电信114搜索引擎:so.114118.cn

    今天偶尔看到,不知道是不是已经Tooold了,搜索引擎包括如下栏目:
    1. 网页、地图搜索使用了微软的Bing;
    2. 比价搜索使用了“聪明点”的技术;
    3. 黄页则是电信的强项,搜索结果中包含商家的电话号码,如果支持Click2Call,则这种模式比现有的各种搜索引擎都更易于广告模式;
    4. 财经、游戏和生活都是原来电信的“号码百事通”栏目
    5. 另外还有一些商城等栏目,没有什么特色

    仔细看看,感觉技术含量并不高。其中特色部分就是黄页搜索,这也是电信的最强之处,不过分词词库似乎有些不好,不认识“云计算”等词,搜的乱七八糟。这和小胡的原型系统似乎差不多:-)

    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。
      电影中常有这样的镜头,中近距离中枪后还生龙活虎,挨了三枪还在那到处晃悠。然后干掉了一位同样挨了两枪的罪犯朋友。 真实情况下,挨这么一枪。胳膊肯定被打没了,不迅速送到医院。小命也会挂掉。。在200米这样的中近距离内,以AK47为例,即使穿防弹衣。也会被击穿。子弹从前面进,是一个很小的弹孔,但在后方会造成碗口大校的创洞--吃过兰州牛肉拉面吗?看看那碗,就那么大。 在真实的战争视频中,曾经有这样的情景。一个美军挨了AK47一枪,大腿彻底失去功能。别说走路,下半辈子基本要靠轮椅了。 胳膊腿中一枪(不是流弹和擦破皮),马上就会失去战斗能力。 不过有特例,就是小日本的38大盖。小日本的38大盖因为过于追求射程,子弹设计又不合理。所以被38打一枪,如果不是要害部位。伤口一般都会很小。

    Pic.2 按要求伪装起来的国民党士兵朱文海,在1939年一次小规模战斗中中弹受伤的一瞬


    2:防弹衣能防弹吗?
     电影中常有这样的镜头,A同志卧底被拆穿。同伙B马上给他一枪。A同志假装倒地,B同学继续无间。 现实情况,答案是不能,现在最先进的防弹衣。也不能防中近距离的步枪子弹。在近距离情况下,甚至不能防手枪子弹。尤其是变态的五四手枪和沙漠之鹰。 而在200米外,防弹衣即使防护子弹。也不能很好的保护战斗人员。高速步枪子弹的冲量之大,没有亲生经历过战斗的人很难想象。 曾经有位美国士兵因为子弹打中防弹衣后,虽然没击穿防弹衣。但震碎了他的5根肋骨,肋骨碎片插进心脏马上死亡。 防弹衣更多的是用来防止弹片和流弹。在中近距离下,少数情况下防弹衣有时候反而会导致伤害更加严重。 所以别以为穿了防弹衣你就牛X,200米内,挨一枪照样完蛋。

    3:头盔
      很遗憾,在中近距离下也不能防弹。在狙击步枪射程内也起不到作用。 也许有人说那把头盔做厚点,但象前面说的那样。中近距离内的步枪子弹冲量之大,如果正面击中。即使没打穿头盔。也会振断你的颈椎骨。

    4:重炮轰击,大家躲在阵地上或掩体里。
      答案是如果你不躲在低下的坑道中。基本会死光。事实上在战场上相当一部分人不是被炮弹弹片直接击中而死,而是被冲击震死。电影中常有这样的镜头,炮弹飞来大家卧倒。炮弹就在身边爆炸。 然后拍拍土,继续战斗。这样的情景在战斗中基本不可能。以二战的105口径榴弹炮为例。一颗炮弹下去,大半个足球场的人不可能生还。不管你是躲在掩体后还是躺在地上。 所以大炮才叫战争之王。在苏德战争中,许多德国士兵就是被震死在钢筋混凝土的掩体里面。

    5:人海战术。
      电影中的“人海战术”只出现在冷兵器时代,和一战期间(导致人海战术退出历史舞台的是著名的凡而登绞肉战,因为马克沁重机枪的出现,英法联军在短短一天内,被打死6万人。) 而现代所谓的人海战术真正的意思是,集中优势兵力攻其劣势兵力。 在战斗中,GCD军队也从没采用过电影中出现的一大群人聚成堆往前冲的战斗场面。 在苏德战争时期,曾经有个德军步兵营在营地修整聚成一堆。结果一炮下来,这个营就被取消建制了。 所以在真实战斗中,都是以战斗队形展开。两人之间大概保持20~50米距离--二战和解放战争中的中国军队也是这么做的。

    6:堵抢眼。
      如果要说物理效果的话,真没什么用。即使你丢个沙袋去堵。也会被机枪打的飞出去。【这一点有些怀疑,估计被击穿,但是不会飞出去】

    IntelliJ 也开源了

    IntelliJ也算是排名三甲的Java IDE,这下子也开源了,从JBuilder倒掉到Intellij开源也没有几年。看上去都是Eclipse给逼的,其实是开源模式正在深入商业主流。各家商业化企业都在试图用开源来吸引更多的客户,这和ISP们提供免费工具并没有区别,不同的是开源比免费更为彻底。从Intellij的情况看,开源可能也有些情非得已的意思,为了支持大量的feature,Intellij可能使用了不少开源的代码,即使有改写,也难免被开源社区质疑。这下彻底开源就消停了。

    Intellij同时还有商业化版本,估计模式和目前的Redhat、MySQL等类似,下面是开源和商业版本你的差异,感觉Intellij还是很强劲的,一点儿不比Eclipse差:

    1IDE 
    2Language

    Microsoft Security Essentials v.s. 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
