These days Tatchee will flee the camera as soon as I point it to him. But this time he initiated and asked me to take a picture of him. Here it is, two boys with big smiles! This was like an one in a million occasion. He has even asked me to load it on the computer!

It was a sunny and clear morning. All of a sudden, a thin layer of fog rolled in just above the water. Boat were moving stealthy under the fog.

This is another drawing from Tatchee, Angry Bird characters surrounded by calculus formula. How did this come about?

One time Tatchee was bugging me to get him a piece of paper for him to draw. There was nothing available. So I reluctantly handed him my real calculus notes, which I was carrying for study. I asked him to draw on the margin. When I got it back I found it adorned with Angry Birds characters.

The original of the notes was on my computer. Usually I carry the paper around and scribble on it. It gets worn out quickly. Then I would update the notes on my computer and print a new one. But this one is so cute I can't throw it away. It ended up become my keepsake.

Tatchee's drawing is getting more advanced. He spend plenty of time copying figures from the popular her TV Ningago all day long. I was particularly impressed by his drawing here because it was seemingly an original composition. This is a rich scene and the master in the sky is a really nice touch. I couldn't find where he get this idea from so I assume he come up with this himself.

Here is something to brag about. It has taken me 6 weeks, and at last I have cracked all 123 problems in the Rosalind Bioinformatics Challenge website. I become the 11th person in the world to have solved all the problems posted.

I have always been curious about science of molecular biology and the related field of bioinformatics. But as a layman in biology, I find it difficult to grasp the concept in any depth. Since someone has introduced me to the Rosalind project, a website that uses hand on problem solving to teach bioinformatics, I was quickly hooked to work on the problems. These range from basic programming and algorithm problem at the beginning, which I have quickly knocked down, to the rather advanced problems at the end. For a few hard problems I have to reach for research papers to find the approach. I feel quite an accomplishment to have done it.
