Source favicon23:53 忙,盲,茫 » DBA notes

这两天没有更新 Blog。借口当然是我太"忙"了,忙得好像一只小蚂蚁。

一旦忙碌起来,情绪也容易波动,失眠、多梦(腰酸背痛腿抽筋?); 忙碌过后很容易陷入盲目状态,眉毛胡子一把抓,企图把所有的东西都搞定,可实际上往往事与愿违,每一个细微的地方都有可能导致大麻烦。盲目之后,所有的事情都告一段落了,可能又会有点茫然,不知道接下来干什么好。

这周一共熬了四个晚上,准备好好的睡一觉再说。

假设文件的大小为3078字节,而TCP包最大的数据容量也就1460(1460=MTU-20-20 = 1500-20-20,HTTP包的最大数据容量比1460还要小,因为还要扣除HTTP包头),因此,要分3个TCP包才能完成此文件的传输。
Source favicon14:49 给开发者测试用的免费i-names服务 » 【刻录事·二零零七】
openID的讨论组中,有人在问哪里有免费的i-name申请来作开发试用。去年i-name正式发布前,有一些提供的,不过后来都停止了,现在i-names的费用很贵,比域名贵,我想这也是它缺乏竞争力的原因之一。 刚才看到 =wil 回说他创建了xrid.net的网站,提供 @xrid 形式的机构i-names,供开发者免费申请该机构名称下的名字,比如我申请的: @xrid*zheng i-names提供两种格式的名称,一个是针对个人的,以“ = ”开头,一个是针对机构的,以“  @  “开头。后面跟上注册的名字,比如我的 =zheng ,它也支持中文,那个人愿意把 =郑 给注册下来? 在申请的名字后面,是允许更上子名字的,比如我可以给我儿子加为:=zheng*kaihong 。注意,中间用的是星号“ * ”。不过不是每个服务商都提供这样的子名字服务。 =wil 则是自己假设了服务,允许用户申请 @xrid 下的子名字。现在这个站点才刚开始,甚至连说明文字都没有。想要了解、测试、开发i-name的人,可以去试用下。 说道名字,想起了second life,他们居然卖机构的名,比如ibm,这样,ibm就能给自己的员工设定在SL社会中的名了,这样也能确保该员工身份的真实有效性。呵呵,生财有道,是不是有必要去了解下费用,然后把国内的品牌厂商的名字买下来?
Source favicon13:24 Unicode中文排序 » Blog on 27th Floor
在Linux下面全面用UTF-8后就曾发现过中文排序有点不理解了,昨天才看到别人讨论,原来Unicode里面的汉字顺序居然是《康熙字典》的偏旁部首顺序。查了一下,康熙字典中的部首共有214个:

一丨丶丿乙?|二亠人儿入八冂冖冫几凵刀力勹匕匚?[十卜卩厂厶又口囗土士夂?逑Υ笈?渝泊缧∞淌??界莨ぜ航砀社酃阚绒眠??驷赆苄母?羰种ш肺亩方锓轿奕赵辉履厩分勾蹯?惚让?掀??鹱Ω肛炽萜?琅H??窆贤吒噬?锰锺怵诎h白皮皿目矛矢石示?禾穴立竹米糸缶网羊羽老而耒耳聿肉臣自至臼舌舛舟艮色?虍虫血行衣??角言谷豆豕豸?赤走足身?辛辰?邑酉?里金??阜隶隹雨?非面革?韭音???食首香?骨高髟?鬯鬲鬼???鹿?麻?黍黑黹?鼎鼓鼠鼻????龠

像在Google Docs里面,如果对Spreadsheet表格排序,中文就依据上面的部首顺序进行,部首在前的字就排在前面,如果部首相同,则算笔划数,笔划数相同的就不知道怎么排了。比如有这样的结果:

刘孙康张李王赵钱?

它们的部首分别是:刀子广弓木王走金?。

又有:刈刘则刹剂剔,文和贝同为4划,杀和齐同为6划,而点在竖前,撇在横前,按传统应该是“江山千古”(丶丨丿一?^)的顺序。另外还有“寒来暑往”(丶一丨丿?^),“天上人间”(一丨丿丶?^),札字(一丨丿丶?^)法,礼(丶一丨丿?^)字法等。

这样用Unicode的话,就是不加任何处理,排序出来的汉字也是很有道理的。但如果想排出拼音顺序就还得再想办法。

查Unicode和康熙的时候,还查到了这个海峰五笔超大字符集输入法,一个用于Win系统的五笔输入法,有86和98标准,最厉害的是:收录UNICODE超大字集全部七万多中日韩汉字,同时他们还提供一个exe来安装这个字体

200calories.jpg
a collection of photographs of different types of food items that contain exactly 200 calories, sorted from low to high calorie density. "when you consider that an entire plate of broccoli contains the same number of calories as a small spoonful of peanut butter, you might think twice the next time you decide what to eat."

Source favicon05:16 Real-time quotes for free » Official Google Blog


At Google, we get excited about making all kinds of information accessible to everyone. The more up-to-date the information, the more valuable it is. This is particularly true in the world of finance; information, and timing of that information, is money. Today, real-time quotes are not freely and easily available on the web. Some websites offer one real-time quote at a time, but typically only after you have enrolled in a service and/or signed a complicated legal agreement. Other sites approach the problem differently and show you streaming delayed data, but that doesn't solve the problem either -- it masks it. What's really important is getting free, easy and fast access to real-time quotes so you know how the market or your company is doing now, not as of twenty minutes ago.

As a result, we've worked with the SEC, the New York Stock Exchange (NYSE) and our D.C. trade association, NetCoalition, to find a way to bring stock data to Google users in a way that benefits users and is practical for all parties. We have encouraged the SEC to ensure that this data can be made available to our users at fair and reasonable rates, and applaud their recent efforts to review this issue. Today, the NYSE has moved the issue a great step forward with a proposal to the SEC which if approved, would allow you to see real-time, last-sale prices across all Google properties including Google Finance, Personalized Google, Mobile, and of course, Google.com. It won't matter if you're on Wall Street or Main Street -- you'll have free, easy and fast access to real-time prices from NYSE on Google.

So stay tuned on our progress with this. We're excited that financial data as we know it is about to change. In the meantime, set up your portfolio on Google Finance today.
