There is no such thing as “expiring” digital content.
It is better to assume everything we share will be permanent and become public one day.

Occupation

Dear students:

I am totally cool if you want to occupy Central, but that should not be an excuse for under performance.

Focus on your math and coding, which one day could let you occupy anywhere anytime without being seen by anyone.

Teaching assistant

TA is a great training for presentation, communication, management, and personal skills. You have to be able to describe course materials in a way that the students can understand, and you have to balance their learning and happiness. Naturally, students want to minimize workloads while maximizing grades. Dealing with a large class (hundreds of undergrad students) is not unlike managing a mob.

It is great if one can focus exclusively on research. That is what I prefer then as a grad student and now as a prof. But without sufficient communication and personal skills, one cannot succeed even with great research skills.
To start with, a great idea is of no value if it cannot be understood and appreciated by people.

Thus, I do not consider TA a waste of time. Quite on the contrary, it is an indispensable part of research training.

Stephen King on how to write

It is striking how much the advice on fiction writing applies to technical writing and conducting research in general, despite some important differences, e.g. scientific writings should be precise instead of leaving rooms for imagination.

Constructive criticism

Criticisms can help us improve, but only if they contain constructive information.

Some examples:

Useless criticism: this result is unacceptable.
Constructive criticism: this result is unacceptable because it contains this specific form of artifacts.

Useless criticism: this presentation is uninteresting.
Constructive criticism: this presentation is uninteresting because I do not care topic X and would rather hear more about topic Y.

As a recipient, I feel excited about constructive criticisms, even if they are harsh or contain personal attacks. In contrast, I usually ignore non-constructive comments because they provide nothing I can act upon.

Non-constructive criticisms are a waste of time at best, and look like whining at worst.
