Database War Extend To Hardware Market
09月 13th, 2009 by huojia
Oracle 收购SUN以后,通常认为Sparc + Oracle Vs pSeries + DB2 会成为市场竞争的焦点。Oracle 在10月14日的 Oracle OpenWorld 上会努力证明Sun+Oracle的组合的竞争力。
在服务器市场开始成萎缩趋势的现在,不知道Oracle这种卖数据库+硬件的策略是否能成为一个黄金搭档。随着云计算的兴起,越来越多的客户并不希望自己来购买硬件服务器,而是更多的透过通过从ISV租赁服务的方式来实现传统的IT服务。
随着IBM Informaiton Ageda版图的日趋完整,IBM 与 Oracle 的战争将愈演愈烈。
Oracle 的战书:
PERFORMANCE
Sun + Oracle is faster.
Oracle and Sun together are hard to match. Just ask IBM. Its fastest server now runs an impressive 6 million TPC-C transactions, but on October 14 at Oracle OpenWorld, we’ll reveal the benchmark numbers that prove that even IBM DB2 running on IBM’s fastest hardware can’t match the speed and performance of Oracle Database on Sun systems. Check back on October 14 as we demonstrate Oracle’s commitment to Sun hardware and Sun SPARC.

在过去的一年里面,我和馒头同学一共吃垮了如下餐厅,不完全统计。通常这家餐厅在上个月或者上周还在营业。这个神秘的规律到底揭示了什么呢?谁能告诉我们。
- 百万庄园西餐厅 展览路店 - 拆迁
- 小区门口串吧 - 改火锅店
- 交大西门酸汤鱼 - 装修
- 清河杨大爷火锅 - 拆迁
- 百万庄园西餐厅 五棵松店 - 拆迁
- 南礼士路必胜客 - 改孔乙己

1) 学习了如何在传统IT软件上面实现云的N中方式,当然,对应不同层次的实现不一样。云这个东西在软件设计里面叫做multi-tenacy.

MSN Space Sync with Wordpress 挂了
08月 25th, 2009 by huojia
周末刚发现WordPress的博客同步到MSN Space的插件挂了。介个Live writer貌似无法同时向多个博客发文章。所以,以后发文章就赶上哪儿算哪儿了。
多博客发布?

强人出没的年代
08月 12th, 2009 by huojia
我的CSS订阅里面,有一类是专门给IT博客的。这部分文章我继承了,只看八卦不关心技术的指导思想。我坚持认为,关注人的本质思想,比关心技术要强大的多。正为所谓,成功取决的是人,不是技术。当然,技术太烂,也一定不能成功。
时间久了,慢慢发现。所谓技术上的大牛,大多还是很喜欢的风月的。比如Oracle的大牛Eygle同学,就很喜欢没事儿折腾几张自己拍的照片到博客上来。弄得一副很小资的样子。再比如DBA notes 同学,就很喜欢给人讲杭州哪儿有好吃的,好玩的。最可爱的是4G Space的同学,其人乃一介IT文人,是我见过的最八卦的IT从业者,居然还是个博士。通过读这些人的文章,我深深的意识到,文学素养不高,是没法在IT圈子里面混的。没有小资情调,是成不了Oracle ACE的。在这个强人出没的年代,如果自己不是强人,也不是文人,也当不起小资。那最好的办法是。。。夹起尾巴做。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。
自己想做点事儿。恩纳
