Sony Ericsson K550i

doiwl January 16th, 2008

又是假期，我回到JB了。

顶不顺那架用了快三年的K500i：joystick坏了、外表斑驳脱漆、显示的号码和拨打的号码不对。

所以回到JB的第二天就买了K550i，woohoo。

设计：撇开按钮小一点，还挺顺眼。
颜色：白色更是好看。
功能：不多不少刚刚好。（3G对DiGi用户没有用）

美中不足的是，为什么打SMS的时候它的反应慢半拍的？！

有时候，按了三下才detect到两下。本来应该是c，它process到b就跳去下一个字了。

也不知道这是k550i的通bug，还是我这架电话的毛病罢了？

docx? xlsx? pptx? mdbx? Open Office 2007 file in older Microsoft Office

doiwl November 30th, 2007

Just another public service posting by doiwl.com…hehe 

.docx? .xlsx? .pptx? Why is there a “x” there and how to open it? If you are asking this question, I guess you are using Microsoft Office 2003 or lower.

The docx, xlsx, mdbx, pptx, those with Xs are default file format of Office 2007. How to open those files?

If this information is useful to you, post some comment la… haha!

Introducing Google Analytics!

doiwl November 27th, 2007

Nowadays, a lot of people have their own blog. Especially when starting up a blog is much easier compared to setting up a personal website last time, where the writer need to have some basic knowledge on HTML.

So dear bloggers / webmasters, do you want an easy way to track the traffic to your blog?

Introducing Google Analytics!
http://www.google.com/analytics/
google_analytics.jpg

What can you do with Google Analytics? Use it if you want to know

  • What is your daily visits, pageview, page/visit, visitor average time staring on your site, percentage of new visits?
  • Where your visitor comes from (geographically)?
  • How do they reach your site? By searching (then what did they search)? By referrals link (then originated from which site)?
  • Their browser, connection speed, how often they visit back to your site?
  • What is the best content of your site? What is the keyword to your site?

In conclusion, Google Analytics is a powerful tools suitable for all bloggers and webmasters. On Nov 19, I noticed a great spike on my daily visits, after that only I realized that that was because I was citing Malaysiakini on my blog. A single “Malaysiakini” brought in more than 40 visitors in a day, that’s something that I am quite surprised.

(Btw, you can only use Google Analytics if you are allowed to change the coding itself eg blogspot, wordpress. Windows Live Spaces, multiply cannot use this…)

安装Windows Vista整整一年后

doiwl November 21st, 2007

21/11/2007 2.58PM 

此时此刻是我安装了Windows Vista Ultimate一年整。我这么无聊去记日期？其实只要在Command Prompt里面打systeminfo 就找得到了。

咦，美国在1月30日推介Vista，马来西亚则是2月3日，那我怎样在Vista还没有launch就install好了？

盗版？不！那是绝对正版的。

Beta Tester

一切就从两三年前说起！想当年我浏览到一个征求XP SP2 beta tester的网站，注册后就开始帮忙测试啦，偶尔也会收到从Redmond寄来的包裹。后来有新的产品有幸继续被邀请，像Longhorn (now Vista), Longhorn Server (now Windows Server 2008 beta), Windows Home Server 等等。重点是不能泄露那些beta build，要遵守NDA，不然会被踢出局的。

虽然是当白老鼠，不过这白老鼠也有甜头的，呵呵！这里就帮这个微软讲点好话啦！微软虽然垄断了市场，但也有慷慨的时候……它送了每位有功劳（至少提出过一个bug）的beta tester一份Windows Vista Ultimate Edition, Retail License。

这是Retail而不是OEM license。OEM和Retail不同是：OEM的操作系统是和电脑硬件“绑死”的。如果哪一天motherboard或者CPU坏了那就可以一起和Windows讲byebye了。至于Retail则不一样，uninstall了以后可以安装在另一台新电脑、新硬件，所以价格还蛮贵的，目前市价是RM1570。

平常我们买到的是OEM，Home Premium不过RM400，Business RM500，Ultimate RM700。若不是因为赠送的版本被规定不能转售，我就可以从OEM和Retail的差价，转卖key就捞个六七百块钱了。

说了这么多，我好像忘记马来西亚盗版猖獗啊，除了公司谁理这么多呢！

嗯，如果你喜欢抢先试用还在测试改进中的软件、或者想要参与Microsoft产品的开发、想要直接和developer/programmer交流、想更了解OS背后的原理、想影响下一个Windows 7的功能，去http://connect.microsoft.com看看吧！

Drastic & Dramatic (Part 3) – Tech talk continues…

doiwl September 21st, 2007

Haha, if it is hard to understand, never mind. My tech-talk continues…

This is the design of yesterday e-voting system.

LOUSY & SIMPLE E-VOTING DATABASE

lousy.jpg
OK… if this is the only thing I can retrieve from the database, can you enlighten me how you show the source of this figure?

In the lousy voting system, the database only holding the latest sum of votes for each candidate, nothing can be done to trace the authenticity of this figure. There is no way to prove the summation is right and not being tampered.

The programmer should really design a better system that allows certain degree of audit. More trails in the database means the system is more error-prone, as follows:

A BETTER E-VOTING DATABASE
detailed.jpg

  • “Student ID of voter” column should be unique, to ensure that a student only vote for once (no double voting).
  • Why is it being MD5 hashed? This is to protect privacy of the voter.
  • The rationale of timestamp, computer ID and other columns are to make it more like traditional paper balloting. 
  • When more trails are left behind, at least we can trace back how many people voted in a particular timeframe, or how many people cast the vote on a particular computer, to judge whether the figure is realistic or not.
  • No one can change the result or insert any data easily unless he is able to fake so many timestamps without clashing on the same time on same computer.
  • Recount & audit is possible.

Aisk, MMU can do it in a professional way and not a joke like yesterday! The staffs did not pay attention on all these things, is it because of the tak apa attitude? Or the decision to use such simple system is made deliberately, avoiding the possibility of audit? No matter how this incident somehow affects the reputation of MMU, when no one pay attention to design a better computer system.
