Happy 100th Birthday to Taiwan/ROC, My Beloved Homeland!

Today, October 10th, is what we Taiwanese called “Double Tenth Day”(雙十節). It’s the day my country declared independence. It’s always been a significant holiday to us, but this year’s Double Tenth Day is even more important to us: It’s the 100th anniversary of my country’s birthday!

ROC is the abbreviation for “Republic of China”. In fact, it’s the official country name for Taiwan.This ROC is different from PROC, People’s Republic China, which is the Beijing government. To realize the relationship and the differences between the two country, this youtube video provides a very interesting explanation:

This country has always been in threat throughout the whole century, but despite the great hardship, we managed to strive to celebrate the hundredth birthday of the country. We should be proud of that!


Recent Updates

Haven’t update my blog for already a month. Looking back at the past month, I don’t think I made much useful work. I am not sure what “research” means to everyone else, but for me, research is a work that the “useful” part presented in the final result accounts for about 10% of total work finished, maybe less. When looking backwards, I might think, “hey, if I do this and that directly, I could have get the result much more easily.” But without those “unuseful” work, I would not be able to get to the final result.

Indeed, often time when I read some papers, I often think: “hey, this is pretty straightforward idea, I could do the same thing within days!” It’s very easy to look backwards, but looking forwards is much much harder.

I just finished a phone interview from Google (looking for internship). Thanks Wei-Min for recommendation into Google. It’s actually my first job interview in the states, whether I get into or not, it’s great experience nevertheless!

I am going to write a report paper to conclude my current research work. After October break, I will switch to a different research topic, which is very very challenging and interesting according to Chip.

Qual 2 Passed!

Whoop! Finally I passed my qual 2 and now an official PhD student!

Through the process of exam preparation, there were a lot I learned. How to read and abstract a number of academic papers in relatively short amount of time, how to do a “useful” presentation that immerse the audience into the key idea of the paper, … and so on.

Though this moment came late in my entire PhD career, I’m still full of enjoyment!

Next step: Look for research topic for my prelim, as well as the potential faculty to form my prelim committee.

Brand New Semester!

Here comes the Fall 2011 semester! Welcome to all new students as well as coming-back students. This semester I will continue to be the CS543 TA, just like the last semester.

CS543 will be taught be Professor Rego. This course talks about simulation and system model in general. This class starts from the basic probability as the fundamental tool in this area. It will also cover topics such as genetic algorithm, Markov chain, confidence interval and so on.

Bug fix for zdelta-2.1

A bug in zdelta-2.1 was found during my experiment. The bug causes memcpy() to fail because of a computation of memory location overflown.

Provided below is a bugfix for this integer overflown bug, as well as a change of macro naming convetion. Since zdelta was modified based on zlib, a few macro definition has naming conflict with zlib. If people, like me, try to include them in the same source file, it would be really troublesome.

Qual 2

Here in Purdue-CS, we have a so-called “Qual 2”, which is an oral exam after the common written qual exam.

I am about to take my Qual 2 sometime end of August, and hopefully pass it once for all. Though my PhD career was delayed by the fact I switched adviser, I’m still hoping to do my prelim by the end of next year.  If Chip’s kind enough, he might let me graduate in 2013, and I really hope to get this degree before turning 29.

But for now, I need to focus on my coming exam and the research papers! Be confident!!

Hello world!

Thinking I need a place to record my thoughts. Facebook and Twitter are all the rages these days, but even though they’re good at keeping in touch with people, they’re not good as an article repository. Blog is still better in this sense.

I’m quite happy that I finally get this domain name. Some one else possessed weichiu.com for years and I couldn’t get it. I started to use weichiu.info as my own domain name, but that wasn’t cool enough. Anyway, here it is.
