Fungible memory

I drew the initial version of the lower-right mushroom from memory, which I realized to be too regular upon looking at the photograph while attempting to upload. I then modified the shape to be less regular and more natural/interesting.
The other two were drawn entirely from memory as I did not capture any photo reference.

Elemental Magic

Filed under: Real — liyiwei @ 10:23 am

This is an excellent book about the principles for drawing secondary dynamic effects, including fluid, fire, smoke, steam, explosion, magic, and solid props.
A hierarchical, coarse-to-fine process applies not only to static drawings but also dynamic animations in the form of coarse energy flows controlling fine visual details.
However, this is not a tutorial book, and one will need (a lot of) practice to really learn (I am currently following this).

The book touches upon digital assistance for manual animation, an exciting and important research direction that also fits my hobby.

Fruits rest

I lost track of time drawing these two apples snugging on the bananas, and did not realize it was past my usual bed time.

What I like to see in everything machine-learning paper

Does this problem require ML, or a hand-crafted method would be better (to control, debug, understand, implement, etc.)?

Is this better for a paper or just open source?

How did you come up with the architecture, and why?

Broken tires

A pile of broken tires around a construction site caught my eye on January 3 2021, especially the lower-left one in a twisted fold. But it was moved towards the fence before I got a chance to draw it.

This video of an interview with the Bumble founder reminds me that the service/mission is often much more important than the technology for starting up a company.

Like others, Tom Brady’s diet and fitness routines got my attention .
I see some positive aspects of his routines, but these might not work as well for others and probably not even the real reasons for his performance.


I have cardio and weight/core training for about 1.5 hours in the morning, a walk between 0.5 to 2 hours (depending on the route and weather) in the afternoon, and 0.5 to 2 hours of coordination/control exercise in the evening.


I usually go to bed around 10:30-to-11 pm and wake up between 6-to-6:30 am, and take a 20 to 30 min nap in the early afternoon.
I guess 10:30 pm among computer scientists is probably like his 8:30 pm among the general public, and I actually need to avoid waking up too early (like 4 am when my brain got too excited).


I usually have fruit smoothie, grain/bean/seed milk, and some dairy (cheese and egg) for breakfast; vegetables, seafood, and carbohydrate (yam, sweet potatoes, bread/toast) for lunch; and vegetables, fruits, and vegetarian protein (tofu or yogurt) for dinner.
I have dark chocolate (often 100 percent cocoa) for morning snacks, hot cocoa (pure without sugar) and green tea matcha as drinks in the morning and afternoon.

I was puzzled by his denial of dairies, and found out it is not based on science.


I meditate everyday, and I probably don’t need additional brain exercises beyond my work and reading.

The takeout economy

Filed under: Real — liyiwei @ 3:42 pm

Ordering stuff online with a click of button can be convenient, but there are potential consequences to our society (e.g., restaurants and gig workers) and environment (e.g., packaging and shipping).

After learning about the charge from a food delivery (tech ?) company during a restaurant takeout, I now try to directly order from local restaurants to build direct connections and bypass these middlemen who can better help the discovery of new restaurants and these dark kitchens that do not want to bother with services and deliveries.

This apple has unhandled extraordinary vertices for its subdivision rules.
