The moment I saw you eating alone facing away from the restaurant window, I understood that I need to live long enough for you.

Review fest

I spent about 63 hours reviewing 23 papers during the last month or so. I did all these during the evenings and weekends so that I can focus on research and coding during “official” work hours. I felt my head is spinning a bit, but such intense reviews are the best antidote for post SIGGRAPH deadline withdrawal which I have suffered in the past as a professor for which paper reviewing felt like the “official” part of the job.

Adobe has this nice matching-grants program which can convert paper reviewing hours for charity donations. So now my paper review efforts can be counted as volunteer activities and I won’t feel guilty next time I don’t give money to random beggars on the streets.

Replicability stamp

The replicability stamp requires more than just the source code, such as datasets and scripts to replicate all results and timing information in the paper.

That may seem a lot of work, but is totally worth it.

First of all, it is a good practice to manage a research project from day one for replicability; a script that can reproduce all current results can help debugging and collaboration. I did that even for my single authored projects.

Even if we have not started the project in that way, it is still worth doing due to the amount of leverage as Andy Grove called in his seminal book “High Output Management”. A single unit of efforts we put in for replicability can potentially benefit many people who want to apply, reproduce, or compare against your works.
You would be more popular, your papers would get more citations and follow-ups, and nowadays many recruiters look at GitHub repos.

The most useful faculty advice I have ever received

From Peter Shirley if I remember correctly:

Do not perform too well on tasks that I do not enjoy so that they would not get assigned to me in the future.

Employee number 88

A colleague who has been with the company for more than 30 years recently retired.
During our lunch at his last working day, I asked him why he wanted to retire. He answered that he preferred his individual researcher + developer role more than management and team roles which tend to happen as one becomes more senior, and he also likes to spend more time with his hobbies in art and physics.

I joked that if I were ever forced to retire I would heist the Federal Reserve Bank of San Francisco. But maybe one day that will change, just like I could not imagine I will ever get married when I was still in school.

Replicability versus reproducibility

Filed under: Real — liyiwei @ 10:18 am

There are some technical definitions (e.g. here), but allow me to put it more succinctly:

Reproducibility – people believe they can replicate the methods and outcomes based on the information provided in the research documents.

Replicability – they can really do so.

Hackathon

In the relative time scale, a 24-hour coding session is more like sprint than marathon.

The last one to watch the last Jedi?

I finally watched the latest Star Wars movie on Sunday night. Avoiding spoilers is a good practice in discipline.

The movie is highly entertaining and has this tinge of smacking the tradition. But I still prefer the original series and even the prequels which are telling the background story of Darth Vader, the most important character of the entire Star Wars universe. The Force Awakens is refreshing, but I am not sure what The Last Jedi is trying to achieve in terms of the story line.

Looking sideways from a stand
For my legacy
