Simplification

“Everything should be made as simple as possible, but not simpler.” – Einstein

When facing a seemly daunting, difficult, or complex problem, a good strategy is to simplify (in the sense of mesh simplification) the scenario as much as possible, during which the thought process can bring great clarify and insight.

VR space warp is interesting and challenging enough, but VR time warp appears even more so.
At least I have no idea how to achieve that for the next SIGGRAPH project.

[Update] The code went to Tejas Shroff, whom I don’t know but who seems to be doing interesting VR stuff.

Stand a chance

Someone asked me whether he/she stands a chance to apply for a position.

Just go ahead and do it. I never care whether I stand a chance or not. The only thing I know for sure is that the chance is zero if I do not even try.

Waking up in the middle of the night, sometimes I can remember ideas from my dreams.

Devil in the house

You brought a devil into the house
It wants to leave
And takes your flesh

So just let it go

Teach yourself and your offspring well
So that none would not be fooled by the devil

Exercise your discipline
To await the devil to destroy itself

If you want to lure it back
Better yourself is the only way

Expresii appy hour

My friend Nelson Chu could not attend SIGGRAPH 2017 to demo his Expresii, so I stood in for him.

Thanks to the wonderful product from Nelson, this is a fantastic presentation experience. I can interact with and talk to many different people, focusing more on practical utility than technical details. I had no time to get bored for the entire 2-hour duration. People kept on visiting even after the session closing. And I had a great time practicing playing the app myself.

Publishing a SIGGRAPH paper is about proving how smart we are, while demoing a SIGGRAPH app is about demonstrating how useful it is for you.

Co-managing research materials

Filed under: Real — liyiwei @ 5:14 pm

Instead of hosting research materials on our own servers (as I did in the old days for both ongoing projects and published outcomes), it is more flexible to share on GitHub/Bitbucket public/private repos that need revision control, and store the compiled files in other services, such as papers on research gate or semantic scholar, videos via YouTube/Vimeo, etc.

With this setup, the co-authors can edit the research together, and I have less to worry about server management.

git obliterate

At the end of trying out BFG to purge a large compiled file from a repo, the following message was displayed:
😀


You can rewrite history in Git – don’t let Trump do it for real!
Trump’s administration has lied consistently, to make people give up on ever
being told the truth. Don’t give up: https://github.com/bkeepers/stop-trump

So with git, one no longer needs to be a rhetor to change the past.
