Time perception

I found drawing to be an excellent in-flight entertainment, especially long-haul flights that provide ample time. Aside from occasional turbulence that can shake my strokes (especially on glass tablet surfaces), drawing is pretty much immune to other distractions like engine noises and passenger commotions.
I had so much fun and focus that the plane landed before I realized.

These two drawings are from the same photo which I like a lot.

Sharing publications

Every time I see people listing publications on their websites without linking to the papers or videos, I hear they say: I am here to show off my publications and I do not really care whether you can access the papers. (Or, in a slightly more excusable scenario: I am too weak to not bow to the publisher request of withholding preprints online for 1 year. BTW this is why I do not submit to CGF.)

Best practice: create a public GitHub repo/page to share all paper information (abstract, pdf, video, code, etc.), so that all co-authors can edit and the search engines can index. (I am doing this for all my recent papers.)

Computer science publication model

If you need to try out a method, which you do first: (1) read and implement papers, (2) compile and run open source codes.

The peer review model for scientific publications has not changed much for centuries. It is about to, at least for computer science and especially for machine learning (e.g. distill.pub), where sharing and reproduction is much easier than other science and engineering disciplines.

Quick sketch from memory

On the link light rail from SeaTac airport to downtown Seattle I saw this intriguing profile, whose delicate structure and hair coverage appeared to be a young girl but emerged to be a lady of at least middle age when she turned her head to disembark the train.

I did not try to draw her on spot because I did not know when she was going to move. I should sketch as much as I could on spot in the future to help recover my photographic memory.

The middle of a flight is a good chance to find people who voluntarily remain stationary.

If there were a superman/superwoman I would expect him/her as benign to us as we to other life forms on earth or even towards one another historically.

Regarding good versus bad aliens, one of my most favorite movies is The Thing (1982), which I found to be much more convincing than E.T. The Extra-Terrestrial released in the same year.

Mediocre people, when they have the right chance, can still hurt better people in unexpected ways. I am glad that I learned this lesson early enough so the damage I received is quite limited.
I am less sure about him though.

The light field camera is a beautiful technology, but consumers find it no more useful than 360 imaging.

Fence

I was searching my email box about the “fence” of the house and surprised to find out how many paper reviews contain the phrase “on the fence”.
