Cat Drinking from Wine Glass

Mayori loves drinking fresh-served water, especially from a wine glass. Obviously she believes that is the right way to drink water for a cat princess.

Mayori loves to play hide-and-seek with us. The top drawer of our dresser is now her new hiding place.

Cat in a pizza box?

Either Mayori believes that she tastes better than the fresh baked version or that she believe that she needs a new bed smelled like fresh baked pizza. Either way she obviously enjoys the pizza box. 


How to redeem British Airways mileages for partner airline flights

Posted on: Wed, 06/15/2011 - 06:35 By: yunyao

I have accumulated over 60,000 miles on British Airlines Executive Club reward account for a while now, but keep on having problem redeeming them. First of all, it is difficult to find any reward flight available; secondly, the fee is extremely high --- for a flight from SFO to LHR, I would have to pay 50000 miles + over \$600 fee, while the same flight costs less than \$1000 when paying with cash.

Over the weekend, I have investigated the problem and found out that one of the best ways to spend my BA miles is to redeem for British Airways' partner airline flights. However, it is not straightforward to do so, as BA would show its own flights with steep fee first, except when American Airlines and a couple of other partner airlines operate the same route.

My solutions for problems No. 76-100 on

Finally done with all the 100 problems listed on so far :-). When new problems appears there, I will probably do them when I have some time to kill, but I will not post my solutions here any more. If I found interesting programming exercises, I may submit to 4clojure as well.

My solutions for problems No. 51-75 on

This post continues the previous one, on my solutions for small clojure programming problems on Doing these problems seems to be addictive as I could not seem to stop myself. The site recently added a golf league feature, so one can see how short one's own solution compared with others. If a lot of people got a much shorter solution than yours, you know you are not thinking in the right way.

My solutions for the first 50 problems on

For someone without previous Lisp experience, the hardest part of learning Clojure programming seems to be the functional way of doing things. It is like math, one really needs to do some exercises in order to master it. At this point, seems to be the best place for getting such exercises. It has a lot of problems for new clojurians to solve. These problems ask one to fill in the blank __ so the given expressions are true. To give a little challenge, some clojure built-in functions are forbidden to use for some problems. New problems are added from time to time on the site, so it surely can keep me entertained for a while.

Develop clojure Web applications with vim

Posted on: Tue, 05/03/2011 - 00:02 By: Huahai

I recently started to learn clojure programming. It is an interesting experience. Ever since I learned computer programming almost 20 years ago, in Pascal, on a VAX minicomputer terminal, I have not experienced this newbie sensation with a computer language. The sense of excitement and novelty is high, and the eagerness to put the language to use is higher still. So for my new project at work, I am doing it with clojure.

This is a visual analytics project, and the visual part will be on the Web. It amazes me how much work has already been done for the Web using this 3 years old language. So it should be easy for me to get started. Here's what I have so far.

A conversation about the job talks of new Ph.D. graduates in computer science

Posted on: Mon, 03/07/2011 - 20:40 By: Huahai

Yunyao and I work in a research center of a major technology company. At this time of a year, we attend job talks every week. These talks are technical presentations given by candidates for our research or development positions, as part of their two day job interviews here. Not surprisingly, the majority of the talks are given by newly graduated computer science PhDs who have published a lot of technical papers in premier computer science conferences. After a while, we kind of see some common deficiencies of these new graduates. Below is an instant messaging conversation we had right after attending a talk, which I hope would be helpful for some people.

YY: How do you like the talk?

HH: good slides

YY: yes, very well made

HH: lack of big picture in question handling

[猴娘]  基督教中国化,会不会产生一个类似禅宗一样的新宗教呢?儒学和基督教的融合,存在什么样的困难?

[东沟]  ...儒家其实从鸦片战争之后就有所蚕食,五四以后开始被踹,文革时候彻底踹倒。然后改革开放的现代化把其经济基础彻底瓦解,连死灰复燃的机会都没了。一句话:我没有说文革十年毁掉中华文化,我说的是文革十年在中华文化的破房子上踹上最重也是最终的一脚。


[火柴]  你真逗,因为不能“三妻四妾趋义弃利三年守孝三从饿死事小失节事大”,所以儒家灭了。因为“满招损谦受益,学而时习之,己所不欲勿施于人”跟普世价值太像了,所以不能叫儒家得叫普适价值。感情叫不叫儒家不取决于自己,取决于别人.如果有一天查理提出个“朋友来了我真高兴”的狗皮膏价值来,我们就得把自个的信仰改成狗皮膏了

[东沟]  听你启发,我要修正以下,“满招损谦受益,学而时习之,己所不欲勿施于人,朋友来了我真高兴”,这些东西就是生活箴言,算不上信仰。
