Calm evening in Frankfurt

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, not least for the career challenges that I need to deal with next.

Team elimination while away

On the morning before my CHI presentation (for a paper whose the first-author/former-intern couldn’t attend due to visa issues) I noticed cryptic messages from two coworkers about soon-to-lose Slack access. Given that we were on the same team, my hunch was that we might’ve be impacted by an organization change.

I gave the presentation as usual which seemed to go well (albeit from some AV equipment issues kindly resolved by a helpful student volunteer) and then noticed “time sensitive” meeting requests from my management chain. (The meeting slots were in my afternoon during which I already planned museum visits, so I took their calls while in the grand hall of Museu Nacional d’Art de Catalunya.) It turned out that my entire team has been “role eliminated” because our project doesn’t fit the new org mission well. We were “highly encouraged” to find alternative internal roles within a 2-month period with partial employee status meanwhile.

If you were me, what would you do? (1) find another job, inside or outside the current employer, (2) take it easy, settle for a more relaxing role or retire, (3) convince your teammates to start up together and see what would happen. I have thought about this potential eventuality for a while, and the answer is kinda a no brainer to me. Counterintuitively, I feel more excited and energized than before when my career has become somehow stabilized.

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.

How to review a draft patent application

Filed under: Real — liyiwei @ 3:31 pm
Tags:

After having a meeting with the patent attorneys, usually you will receive two documents to review – a Word document with texts and a PDF document with drawings.

Aside from using LLM to summarize the former, a good strategy to review the documents (without falling asleep) is to look at the drawings for a visual overview, and then read the high-level sections, like the abstract, the background, and the claims, before the detailed description when necessary.

You might find the legalese hard to understand even though they are supposed to describe your invention. This is expected, as the the patent is often worded as a defense against infringement, so just make sure that the claims are broad enough to cover your invention but not too broad as to be non-patentable.

Don’t submit if you can’t review

With SIGGRAPH, TVCG, NSF, and CHI I ended up reviewing 30+ submissions this month. It was quite some extra work, especially for an industry researcher who doesn’t have to serve on academic review committees. But I am glad that I would get (forced) to read topics that I usually would not, and really appreciate those who accepted my review invitations.

I am also surprised by the reluctance of some to review papers, especially for those who are in the academia whose careers depend on getting their own papers accepted and grants funded. If you are too busy to review other people’s submissions, you probably shouldn’t submit to begin with. Who should review yours then?

Dystopian reads

Over the holiday season I read the following books (all in audio or electronic formats via hoopla), which, in retrospect, seem to depict one form or another of dystopia:

  • Careless People by Sarah Wynn-Williams
  • Symbol Formation in Psychoanalysis by Marisa Pelella Melega
  • 1984 by George Orwell
  • Black Box by Shiori Ito
  • Fall by Neal Stephenson

And I would say that reality beats fiction.

Pottery

For someone starting 3D modeling digitally—not counting the pottery class as a kid when he spent most of the time throwing clay to the ceiling—he found manual modeling to be both challenging and satisfying. The challenge came from technical precision (e.g., wedging the clay to the right stiffness, centering the clay on the wheel for throwing, trimming the clay to the right shape, and glazing the clay to the right combination of layers and colors), while the satisfaction arose from intuitive direct manipulation and the visceral feeling of clay in hand.

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.
