F*** you money

Filed under: Real — liyiwei @ 1:15 pm

I did some calculation a while ago and concluded that no amount of money will suffice. Instead, it is much better to have f*** you talents/skills/capabilities.

This recent case, as reported by wired and bloomberg, may have a good chance to prove my conjecture.

Ghost in the Shell

Filed under: Imaginary,Real — liyiwei @ 5:20 pm

There is a peculiar kind of pleasure for senior people to reminisce their junior experiences, as I discovered after getting older.

The first trailer closely matches the original anime, which is also available on Netflix.

Like many contemporary Japanese anime, the story can be confusing for people not familiar with the genre. But it seems quite clear from the second trailer, and different from the original story.

Race can be a sensitive issue for Hollywood, but watch how the Japanese react to the casting of this movie. This should be no surprise for people who understand the Japanese culture in general.

What is the best way to make people want to watch a commercial?

The hedgehog and the fox

Things are usually not all black and white, and worth further study before jumping into conclusions.

The travel ban of the seven Muslim majority countries is both cruel and ineffective, even though it might help me recruit students.

As reported in this NYT article written in 2015, the current H1-B visa system has plenty problems. Instead of a random lottery to address the over-demand (by mostly outsourcing firms), it is better to use a more market-driven system, e.g. giving higher priority to higher paid foreign workers.

In general, a skill-based immigration system, similar to what currently exists in Canada, can be better than the current family-based system in the US.

360 video is not VR

Filed under: Real — liyiwei @ 11:52 am

VR (virtual reality) can offer true depth perception with binocular/vergence, parallax/motion, and (if possible) focal/accommodation cues.
360 image/video supports pan and zoom, but not real 3D depth, not least motion parallax. It is a form of IBR (image based rendering), but not VR.

Combining multiple wide angle videos/images has been a hot topic in the late 90s (for those of you who are not old enough), but rehashed to ride the recent VR hype wave.

I cannot wait to see these two teams play again in the NBA finals. 🙂

Paper length

The obsession with paper length is a legacy of printed proceedings.

What matters most is readability.
I would rather spend 1 hour reading a 20-page paper than 2 hours reading a 10-page paper.

Then follows file size: the smaller the better for storage and transmission.

Altruism is the ultimate form of selfishness

Filed under: Real — liyiwei @ 12:30 am

Recently, a student told me that he is not all that motivated for his own first-authored project. And yet he asked to help other projects because he could get extra papers without doing much work.

If I am not sufficiently motivated in a project, I am unlikely to contribute enough to help my team succeed. Even if it does, other team members will remember me as a free rider. I might as well do something else.

Jun Xing PhD defense

Filed under: Real — liyiwei @ 2:07 am

I have been the shadow adviser for several PhD students before.
Jun is my first official PhD student, who just successfully defended his thesis.

Do not expect me to completely turn to the light side though. I still prefer external advisees, and will continue to be very selective in taking internal students; there are only two so far.
