Straight strokes

Filed under: Real — liyiwei @ 3:55 pm
Tags: , ,

For some mental or physical reasons, I lack control for hand strokes.
As a little kid, I was told by the school teachers that my handwriting was so bad that it will dim my future.
But that shortly became a moot point right before I started programming on computers.

A few decades later, when I started to pick up drawing, one of the first instruction books advocates practicing straight strokes before anything else, which paused my progress for years as I never have the patience for rote practice.
I later switched to another book that emphasizes natural contours, which jump-started my drawing progress.

I still cannot control hand-strokes at this moment of writing, but that doesn’t seem to matter, and I haven’t even turned on automatic stroke smoothing common in drawing applications.

Advices can help, but only combined with our own unique situations.

Pricing bananas

Filed under: Real — liyiwei @ 4:28 pm
Tags:

I noticed widely different prices of bananas across groceries in my neighborhood:

Trader Joe’s (Menlo Park): $0.19 each (regular)
Whole Foods (RWC): $0.69 per lb (organic)
Key Markets (RWC): $0.99 per lb (regular)
Roberts Market (Woodside): $1.29 per lb (regular)

Which made me wonder how groceries set up prices in general.

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
Tags:




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.

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.

Exercise

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.

Sleep

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).

Diet

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.

Mind

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.

The biggest bluff

Filed under: Real — liyiwei @ 1:57 pm
Tags:




Gist: the author, with a journalism and psychology background, decided to pick-up poker from scratch as a way to learn how to deal with randomness in life and focus on what we can control. The poker part serves as the training platform and medium of investigation for the author, and even without knowing anything about poker, I found this participatory journalism highly entertaining and yet educational at the same time.

At the end of the book, the author said that she plan to continue with poker instead of ending it after completing the journalism project.
I wonder if this is the best use of one’s time and talent; poker is a zero-sum game and contributes even less to the world than finance, which also moves things around but at leas can claim to increase market efficiency.
As a research scientist and product engineer, I would much prefer to be able to create things and solve problems, with even more opportunities (and necessities) to deal with external randomness and internal control.

Being attentive

Filed under: Real — liyiwei @ 9:25 pm
Tags:

I was reading this book chapter about a group of poker players at a game table, some closely observed every play and some just focused on their own thoughts.
The former can learn others’ habits and adapt their betting strategies, while the latter can bust out even with a mathematically good hand.

This made me realize that I could have paid more outward attention and less inward looking to the different situations I have been in, from daily conversations/meetings (too much self distractions) to international jobs/travels (too little observation these different people and places).

This also relates to a maxim of meditation, of being present, which can enhance happiness and productivity.

Fairness

Tedros Adhanom Ghebreyesus said it was not fair for younger, healthy people in richer nations to get the jab before vulnerable people in poorer states.

If we continue this line of reasoning, is it fair for younger, healthy people in richer nations to receive more heath care, social welfare, etc., than vulnerable people in poorer states?
How should we define fairness across different groups of people?
Is such fairness achievable or desirable?

Lesson learned: keep the due diligence and never let my guard down.

Common law versus civil law

Filed under: Real — liyiwei @ 12:12 pm

Quote from here:

The main difference between the two systems is that in common law countries, case law – in the form of published judicial opinions – is of primary importance, whereas in civil law systems, codified statutes predominate.
But these divisions are not as clear-cut as they might seem. In fact, many countries use a mix of features from common and civil law systems. Understanding the differences between these systems first requires an understanding of their historical underpinnings.

So, common law is data-driven while civil law is procedural.

How to deal with randomness in life

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

[This is my reply to a co-author who expressed concerns about the randomness in peer reviews.]

During my military training, a saying went like 散彈打鳥不死也傷, which roughly translates to “if one shoots enough bullets into a forest eventually a bird will be hit”.

(There are others related quotes such as “the best way to have a great idea is to have a lot of ideas” by Linus Pauling, but shooting bullets feels more concrete/visceral.)

Other things being equal, more attempts tend to reduce statistical variance and increase the numbers of success.

Rick retiring

I received an announcement earlier today that a prominent member of our research community is scheduled to retire next month, which made me think about what it means for a research scientist to retire.

To me, it means all the extra time and freedom to do whatever I want, such as single-author a SIGGRAPH paper in an exotic topic that I wouldn’t be able to find support from funding agencies or company managements. (I used to joke with my students that I plan to single-author papers when I am 88 years old.) But I have yet to reach that biological and career stage, so I cannot predict what I can or want to do then.

Maybe I will write a follow-up post when I turn 88.

Epistemic dependence

Filed under: Real — liyiwei @ 11:16 am
Tags: ,

I found this article a nice read, which highlights the much faster growth of our collective knowledge (accelerated by computers and algorithms) than our individual brain capacities (constrained by biology and evolution). Each one of us knows a shrinking slice of the world, and this has profound implications on our society and civilization.

One, as mentioned in the article, is the increasing need of collaboration among researchers, especially for experimental science. (At this moment of writing, it is still feasible to single author a computer science paper.)
Even though the numbers of co-authors of my papers have not increased too much, I do find it increasingly harder to know exactly what is going on in every aspect of a project, notably detailed implementations and user studies.

Another timely topic is about politics.
The policies can become so complex that nobody really understands what is going on.
Thus, each voter knows only a tiny aspect of each political topic or candidate, and thus can form drastically different opinions from one another. This can be a scientific factor driving political polarization, even without other factors like social media. Fortunately, Monte Carlo sampling indicates that with enough (sufficiently independent) samples, the aggregate estimation can still be robust (low bias/variance).
For example, the US essentially has 100+ million votes for the presidency, which should give us confidence on the outcome, no matter how ridiculous it may look.

I used to think the acorns were dropped on the roof by the squirrels, until this afternoon when I spotted these crows, which I didn’t manage to photograph on spot but drew one later based on visual memory and online photos.

Research goal post

Filed under: Real — liyiwei @ 10:09 am

In my personal experience, there are two ways to guide a research project: solving a specific problem with whatever solutions that work the best (based on a variety of criteria such as quality, speed, cost, etc.), and devising a novel idea that can span different problems, domains, and applications.

The problem-oriented approach happens more in engineering (which aims to solve practical problems) while the idea-oriented approach happens more in science (especially more theoretical fields like math which aim to formulate fundamental ideas behind a plethora of phenomena).
Solving a specific problem provides a clear goal and reduces the tendency to derail, while aiming for ideas is more likely to work after one has already worked on related problems so as to condense the experiences into the core forms.

What can be quantified can also be automated

Filed under: Real — liyiwei @ 10:00 am

If the productivity of certain types of works can be quantified, it can also be optimized and thus automated.

Instead of performance evaluation, such measures are better used for identifying repetitive tasks potential for automation.

To achieve human-level intelligence, we probably need an AI framework very different from existing rule-based (e.g., Minsky) and data-driven (e.g., current ML) approaches.

I drew this fun exercise with reference photo(s).

I found FB an excellent venue for virtual drawing archive: unlimited storage, albums for organization, “memories” for reminding/checking progress, social sharing (or peer pressure, depending on how you look at it) for motivation, and no known privacy issue (how to target ads based on drawings, aside from generic Adobe CC subscription?).

Tree remains

I saw a newly chopped-down tree on Monday evening, came back this evening only to see its remains already cleaned away, and drew from visual memory/impression.
Interestingly, I can draw this one faster and better from memory than onsite, probably due to the mental abstraction already took place.

Vertical versus horizontal colleague

During the last 1-1 with a direct report who will transfer to another team, I found I prefer talking to him as a friend than as a manager.
I wonder if this reflects my style of influencing.

The amount of details should be proportional not only to the intended emphasis but also the unintended confidence about the specific drawing regions.
I did not have enough time to observe the legs (before they moved), and found out that they are better left only roughly sketched.

In nightmares, Jorge Luis Borges mentioned about the mesmerizing painting by Henry Fuseli, which inspired me to paint over my variation to reflect the current political atmosphere.

The reference image sources: incubus, statue of liberty, elephant.

Portrait requires high precision to look right.
The lockdown has reduced my chance to draw people on-site, so I switch to photo references meanwhile.

I had this dream half a year ago on on March 27 2020.
Upside down helicopter man fly over a city.
Rotor stopped and dropped to the ground, captured by a GoPro camera.
Rescue workers brought a big net rushing towards the camera view, which I replaced by an ambulance view for easier drawing.
