Month: September 2018

I don’t have another notebook, as they say, I can’t recall anything in the morning 🙂 This is about script->pdf tools.

For texts, I periodically use latex; for diagrams, I try to use console tools that convert scripts into graphic form. For flowchart, sequence diagram, and gantt, I use mermaid (https://mermaidjs.github.io/), for sequence diagrams I also use graphviz (https://www.graphviz.org/), and just today, I installed and tested erd+graphviz, a package on Haskell.

I’m afraid next time I won’t be able to find this from scratch, so it may as well hang here, searchably.

Got engrossed in a new book by Yuval Noah Harari, “12 lessons for the 21th century” at B&N. This is the same guy who wrote the wonderful Sapiens and Homo Deus. Nearly parted with 30 dollars in my mind, but then found this book on VKontakte, and, delighted, bought a pastry for five. Last time, we found three books on the art of essay writing there, and bought all three directly from the bookstore on thriftbooks.com for a price five times cheaper (they were used, but it didn’t matter to us). It’s tough being a bookstore these days. I think B&N needs to transform into something fundamentally new in the coming years. Since 2015 their stock has fallen fivefold. Perhaps they need to hold public lectures and educational events in stores. Nowadays, it’s hard to even find a consultant there. Before, there used to be a computer in the center with their in-store search system, now even that’s been removed. What do you think is the future for offline bookstores?

The sign reads “cool descent ahead”

An interesting discussion, both sides are trying hard to defend their viewpoints, but the priest isn’t performing very well. Nonetheless, his level was higher than I expected.

Liza at work. Mastering charcoal. I’ll post a photo of the charcoal piece she used to draw this in the comments

The service allows you to upload your photo and get a 3D model. You can even use it with a photo of the president.

Tried uploading myself – it turned out pretty well.

Here are the details:

Here is another work by one of the authors – already with human figure modeling:

Konstantin Kharitonov you seem to understand this. Why isn’t there a tool for creating a 3D model of a person in motion (by taking photos of them from multiple angles, asking them to make various facial expressions, possibly by projecting a laser grid on them), then process what was captured, and by combining it with some universal knowledge base about human anatomy, achieve a 3D model of a specific face, which can then depict any desired facial expression on a computer just because a) muscles work the same way in all people b) the model knows the ranges in which certain muscles move c) the model knows how the skin, eyes, mouth, and ears look when certain muscles are tensed or stretched.

After all, no one limits us in the number of photos taken from different angles and under different lighting conditions. So even if there are a million photos, it’s no problem, we’ll wait. But then, the system could extract the photo from the needed perspective under the required lighting to render realistic expressions of a specific face for any artist’s requirement.

I imagine this as a framework for 3D designers, allowing them to simply specify any facial expression, but also to alter the face itself (e.g., widen the eyes or protrude the nose). With a 3D model from a camera, import these facial features from a “scanner”, as well as the skin texture for more accurate rendering.

Is there such software?

Lots of fascinating video reports from Berkeley labs

It turns out that the sugar content in horseradish ranges from 6% to 13%, while in radish it ranges from 1.5% to 6.4%. In other words, it is generally possible to find horseradish that is not sweeter than radish, but more often than not, it is sweeter.

Hmm…
