Our hero, Shrek, was just one step away from saving princess Fiona and getting his beloved swamp back. However, the gate to the highest tower in the castle, where the princess was imprisoned, was guarded by a mighty Dragon. Fortunately, considered herself as an intellectual, Dragon refuses a battle of life and death, instead, she gave Shrek a puzzle to solve in order to pass through the door. It is as follows:
Given a 4×4 square (a) as below and a palette of 4 different colours represented as 4 different digits, can you produce the shortest sequence of digits such that I can perfectly reconstruct the square from?
With coloured box is encoded as a digit, can you encode the 4×4 square (a or b) as a sequence of digits such that it is the shortest and one can easily reconstruct the square from perfectly?
There was a time, scientists had to predict nature with pure reasoning and looked for affirmative from observations. There was a time, practitioners could barely scan through all the possible solutions to analyse the correctness of a problem, and thus had to ask for help from mathematicians. And, there was a time, when mathematics listed a method as hard to solve (in terms of polynomial time) in principle then it came out to be a good fit in practice. Among those, there is Linear Programming (LP).
Sometimes, a push in the back is what one needs to move forward, regardless how she is fully aware of what happening surrounding her or the right decision to make. The astonishing voyage of Professor Randy Pausch is that kind of catalyst, a sequence of childhood dreams come true, and an optimist man shares his life in the racing with the death sentence of pancreatic cancer in no more than six months.

This movie makes me feel like riding a roller-coaster of emotions, from ‘ehh’ to ‘wow’ then ‘nooo’. For the same reason as Inside Out, I feel have got enough of those new animation styles, which is no match for the era I was born, when artists used actual paint to create Snow White or Robin Hood. Besides, who cares how feeling feels, or a heroic young boy chases his musical dream,…pft, whatever. I can close my eyes and instantly tell you numerous patterns which a story could follow, from my experience in competing my dad to see who can guess what comes next on usual TV show. Therefore, I could proudly challenge people to tell me a story that I can barely know the end before it explicitly stated. Read More
After September 12 Apple-event, the news of the new iPhone X and its cutting-edge facial recognition technology, namely FaceID, run all over the place. Besides a big leap in price in mobile-market making people suddenly be aware of their internal organ value, an inevitable question pops up about the reliability of FaceID. On one hand, it’s totally convenient to look at the screen and the phone automatically unlocks itself. On the other hand, such kind of privacy protection was proved to be imprecise from time to time and could be faked by a whole bunch of simple (or not) tricks: a photo of the owner, her video, or even a 3D model.

While writing these lines, I feel extremely disappointed and outrageous at the same time. Before coming to any conclusion, let me remind you that I am a Vietnamese as well, so this means no offence in any sense.
I now in a middle of a Bioinformatics summer school, in which fortunately I was accepted to be a TA. Needless to say, this means a lot to me – one of the first steps in my academic career and helps me to explore what I am capable of and do best. Read More
Lately, my supervisor asks me to set up an academic web page, which is an inevitable thing anyone should do in their academic career, especially in Computer Science. With a little help from friends, I eventually figure out a general way to make one. Read More
This book review is about my overall evaluation after finishing the book. In addition, not only do I summarise the key ideas in each chapter to provide more insightful of the lessons I have learned, but I also try to share my thought relating to personal experience. The book consists of 7 chapters, which I spent 1-2 hours for one chapter per day, though the contents vary in difficulty level and some require basic prior knowledge about probability. Read More
The first time this book raised interest in me is when it was mentioned in the movie Conspiracy Theory (with Mel Gibson played as main actor). Thus, I am wondering why a New York taxi driver, who always has his own explanations for every events occurred on the news related to interference from government, is obsessed with buying a copy of theCatcher in the Rye every time he found one. Recently, I have a chance to find the answer on my own. Read More
