Wake-up call

During a physical training exercise today my sifu pointed out that I haven’t been making as much progress as I should have in all these years, because I haven’t been putting in enough focus and effort.

This triggered me to realize that this generalizes to other areas of my life as well.
I was very motivated and hard-pushing earlier when there were specific goals and expectations, such as getting good grades, attending prestigious schools, getting posh jobs, publishing top papers, and such.
However, as time went by, the goals and expectations became less well-defined and the pushing became less intense.
Eventually I just took it easy and settled into a cruising mode without realizing it.

Thanks to this wake-up call, I am getting back to my previous self, starting from this physical training class, and other areas of my life as well.

Cheerful, suicidal

During my morning Caltrain rides I often see a guy waltzing across the train fist-bumping and chatting with passengers. Today I came to meet him again, and I took the chance asking him why he is so cheerful.

“I am suicidal” was his reply.

The conversation was overheard by a nearby train conductor who later brought another conductor towards me and asked me to repeat what I heard. Turned out that they need to report such cases to the police to prevent suicide attempts.

Remembering professor Hsu-Chun Yen 顏嗣鈞

Professor Yen was one of my favorite teachers in NTU EE. I really enjoyed his discrete mathematics class and a special project on reading computational theory papers. In my eyes he was a very smart and caring professor. He even went to the same junior high school as I did.

I learned that he has passed away from a recent department newsletter. I couldn’t get a chance to say goodbye to him but I will always remember his kindness and appreciate his teaching and guidance.

Long wait at FRA

After a calm night at the hotel without having much else to do in the morning after exercise (great pool!) and breakfast, I headed to the airport earlier than usual. This turned out to be a good decision as the immigration lines were very long and only a few agents were present. It took me an hour to get through while witnessing all sorts of complaints and line cutting (from passengers and flight crews), the sheer incompetence of the airport staff, and the indifference of the immigration officers.

A bunch of Indian folks behind me said that they have encountered similar situations in other airports in Europe.

If this is a sign of Europe, I am not sure if anyone wants to visit again.

Calm evening in Frankfurt

[This post was typed directly into my WordPress site on an iPad, so bear with me for potential typos.]

Upon arrival at FRA from BCN I was notified that my flight to SFO has been canceled. Walking around the airport check-in area for about 40 minutes without being able to find any opening UAL counters, I finally bumped into a guy who told me to stay around for hotel arrangements (and all the UAL counters have been closed for the day). As you can imagine, there are hundreds if not more such stranded passengers all throwing questions and complaints to the guy.

Finally he led us to the hotel shuttle bus area, and I walked by him chatting him up. I told him that we were like a bunch of kindergarten kids following a teacher and he had to deal with all these unhappy faces. Turned out that he is an airport hotel relationship manager and doesn’t work for the airlines. He seemed happy enough that he put me into the hotel for business class passengers even though I booked only an economy class ticket.

When checking in at the hotel the receptionist only asked me to write down my name and the airline without checking any identification or flight ticket, so in theory anyone can just walk in and claim to be a passenger with cancelled flight (at least during the days with cancellations informed by these relationship managers)?

I was put into an executive suite and there is a nice indoor swimming pool that I can finally put my swimsuit to use (the outdoor pool in my Barcelona hotel wasn’t that warm so I just used the gym during my stay for CHI 2026).

Later I bumped into him again in the hotel lobby and asked for his business card.

Calmness during ordeals pays off.

Picasso museum

Visiting the Picasso museum near the end of the day in Barcelona I was struck by the sheer number of drawings and paintings that he has created. This is probably another evidence that excellence is not just about talent but also a lot of practice.

Nocturnal excess

After having caesar salad, two balls of mushroom truffle arancini, and a piece of salmon with mashed potatoes, he should have taken out that large piece of chocolate cake instead of eating it which causes some physiological reactions later in the night.

Cold water exercise

The swimming pool was cold, no longer heated after the winter heating was turned off due to budget cuts. So he did some high-intensity exercises for about an hour to warm up before spending fifteen minutes (about a quarter of his usual swimming time) in the cold water.

The initial shock felt more like pain than cold, but it subsided after a few laps. It felt rewarding afterwards, especially with the hot spring soaking.

He then took a cold-water shower while waiting for the hot water to gradually arrive, experiencing similar cycles of sensations.

Post-holiday rust

After a holiday, he returned to work and started with implementing a new feature as a warm-up.
After merging the first pull request, he realized it was buggy — he had forgotten to test another major aspect of the prototype — and ended up needing three more pull requests to complete the job.
