yantrams··on Racket: Lisp for Learning
I believe you're referring to this thread. https://groups.google.com/forum/?hl=en#!topic/racket-users/y...
yantrams··on Ghost Army: The Inflatable Tanks That Fooled Hitler (2013)
Damn I remember reading up about what was probably a reference to this as a kid in the beautifully illustrated Russian History in Tales (https://www.goodreads.com/book/show/7791688-russian-history-... )

The article says this was declassified in the 90s but I distinctly remember a story from the book about fake tanks to fool the German army.

Bergson it is thank you!
yantrams··on Ask HN: Trying to recollect the name of a 20th century philosopher
He wrote a treatise on the nature of space and time and I believe his surname was Bergman.
yantrams··on Why Generalists Triumph in a Specialized World
On a somewhat related note, I often wonder why Poincare is still considered the last of the Universalists/Generalists. I believe Von Neumann would be a strong contender to that title.
yantrams··on India heatwave temperatures pass 50 Celsius
This has been the case almost every year this decade in India.

Also, it is quite common for the government departments to fudge data and report temperatures > 50 Celsius as 49.x to avoid halting work / paying extra to those working under the Sun because there are regulations concerning this.

Edit: I got to know about this practice being rampant through an activist in the South who is well versed with the labour laws.

yantrams··on Who Killed Lard? (2012)
That Upton Sinclair's novel bit on people falling into vats reminded me of Ambrose Bierce's macabre short story 'Oil of Dog'. [1]

There is even a beautiful animated adaption of this tale titled "My name is Boffer Bings" on Vimeo that was released few years back [2]

Here is a great primer on entropy that you might find helpful - http://colah.github.io/posts/2015-09-Visual-Information/
yantrams··on By the book: reflections on an Indian childhood reading Soviet hardbacks
Never heard of it. Will check it out. Thank you!

PS: One of the highest points during my college prep days was when I managed to solve this kinematics problem from Krotov where the condition for a ball bouncing in a well to get out depends on the ratio of some parameters to be co prime. Good times.

And the smell was amazing too :)

You're welcome :) Memorable tales and gorgeous illustrations. This is one of the few books I managed to keep in absolute mint condition :) I have a scanned version lying around in my collection. Will upload sometime soon on my blog.

Landsberg's series on Elementary Physics[0] would be a more appropriate counterpart to Resnick & Halliday etc, targeted towards those preparing for university exams. Narosa has a great collection indeed.

Interesting to know that!

For REAL bragging rights, you had to solve Krotov :)

Yakov Perelman forever! Are you referring to the limits book in dialogue format ? I came across one few years back.
yantrams··on By the book: reflections on an Indian childhood reading Soviet hardbacks
I can't emphasize enough how important these books were in shaping my childhood in a rural town in India. I still vividly remember making a fuss when Misha and Sputnik stopped after the fall of Soviet. A part of me is forever indebted to Russia for this.

Given the strong Communist presence in Andhra Pradesh, the state I am from, we were lucky to have a great number of these books translated to Telugu, by no less than legends like Sri Sri.

I have some of the children's books uploaded on my blog at http://linkdot.link/sooviytt-prcurnnlu-childrens-books.html

PS: I named my daughter Aelita after the science fiction classic.

Story of my life too, including the 15 years part! Every once in few years, when I feel like my memory skills are fading, I recite the damn key, pat myself in the back and go back to sleep.

I believe the legendary Project Xanadu has an interesting approach, possibly restrictive, for dealing with this issue.

yantrams··on A Man Who Questioned Everything
There is a passing mention of Diderot in this book I'm currently reading - Mathematics, the loss of certainity by Morris Kline. It is quite fascinating to see how his view on Mathematics in 1750s was similar to that of the 20th century formalists.
yantrams··on A 13-year-old girl reportedly makes over $1,000 a day creating ASMR videos
That's very interesting! Thanks for taking the time out to comment. I'll post it on Reddit and see if I can get more info. Feel free to reach out to me through email. You can find it here - http://compute.vision/

Cheers

yantrams··on A 13-year-old girl reportedly makes over $1,000 a day creating ASMR videos
I got to know about ASMR recently thanks to the video that was taken down and the description felt very similar to what I've experienced since I was a kid. I used to even flaunt this as a super power when I was young. Wondering if someone knowledgeable could explain-this-phenomena / suggest-some-literature to me. Reddit probably is the right place to enquire about this but here goes nothing.

I can spontaneously generate this tingling feeling at will by moving my chest muscles ever so slightly. This act lifts my shoulders a tiny bit and results in a mild pulse descending from the back of my head that flows through the spine. Doing this continuously 3-4 times results in goosebumps in the right weather conditions.

I got a similar feeling(comparitively milder than what I could generate spontaneously) when I watched/listened-to one of the ASMR videos which made me wonder if there a way to quantitatively measure these ASMR responses claimed by people.

Nice. Unfortunately it stopped working after a couple of results. I get this google maps error now - https://imgur.com/a/Yf9Bv5l
yantrams··on Neural Networks, Manifolds, and Topology (2014)
This was the article that helped me get neural networks when I began studying them few years back. Interpreting them as a series of curvillinear coordinate transformations really helped me understand them better.

PS: There is a great introductory article on entropy on the blog that is worth checking out.

I scraped it from their website and then asked for their permission by sharing this link with them. They appreciated that I linked all the icons to their website and gave their consent to make this public.
yantrams··on Show HN: Search icons visually
Ouch. Sorry to have put you through that :/ I will fix it asap. And I agree with the parent too. Maybe some text below the horse that says fetching results... would make things clearer.
yantrams··on Show HN: Search icons visually
The MPEG-7 dataset[0] is what most researchers use to benchmark shape similarity algorithms. There are couple of other datasets that I used that I can't recollect now. These datasets are relatively simple with a single shape as opposed to logos, icons that comprise multiple elements in different configurations.

I would test on the MPEG-7 dataset to begin with and once the precision and recall values are good enough go ahead with testing on logos and icons. I must've manually tested the algorithm more than a 100,000 times probably because that was the only way to do with untagged datasets. Quite tedious indeed. This version gives out pretty decent results about 7-8 out of 10 times I'd say.

Ah yes. This has to do with the thresholding 'bug' I discovered sometime ago. I will update the algorithm soon. Happens with color images in the preprocessing stage during the conversion of query image to a binary image, especially in images with flat/palette colours.

I eventually came up with a contrived set of heuristics to tackle this problem as you can see in the example below and managed to get more get accurate thresholding more than 90% of the times for pathological cases like these with the right set of weights. --- https://imgur.com/a/XMhdnjH
