nomemory··on An animated introduction to Fourier series
The animations were done using p5.js.

The source code can be found here: https://github.com/nomemory/andreinc-site/tree/main/assets/j... , but I am not satisfied with it. I was learning p5.js while writing the article.

It happens to me when I am using Chromium under Linux, it seems that my Hardware acceleration is not working. While on MAC, Windows or Firefox (Linux) it works flawlessly. On mobile is choppy as well (unless you have a flagship).

Unfortunately I didn't know how to optimise the animations better, and once I found out, 90% of the code was already written.

nomemory··on An animated introduction to Fourier series
Thanks for noticing, the source code for all the animations can be found here: https://github.com/nomemory/andreinc-site/tree/main/assets/j...

It's not something I am particularly proud of, as I was learning p5.js while writing the article, so I've started doing things in a very inefficient way.

When I have some spare time, I will update the article accordingly to include the correct links.

I suspect a lot. He has unorthodox views on lots of topics. For one he doesn't seem to believe in the heat death of the Universe. He has some interesting theories in regards to gravitational waves and so on.

I've never considered myself the "flexer" type, but maybe the tone of the blog post was a little misinterpreted.

PS: Great stuff you've shared. I remember in the past I've spoke with you about b-trees.

I use marginalia more to find blogs and explore personal sites. I think I visit the site daily.

Have you tried kagi?

The star means no 0. It might be redundant, yes.

We used the notation for Real numbers strictly greater than 0.

That's cool observation.

It's a good reflex when you see the sum of two squares to think at the Circle.

1 Author here. I did my fair share of competitive math in highschool, but never got to the National phase (although two times I was very close, like 2 points close). The amount of grind for that was too high for me, and I also had other interests. All in all, the regional phase was also quite hard (most of the problems are from the regional phase). We were not told why we solve the problems, we considered the problems to be more like teasers and puzzles.

Years later, I've realized they helped me to get some sort of mathematical intuition of things that was enough for me to finish an Engineering degree without having to struggle too much with math. All my colleagues who participated in the contests felt the same.

To this day I believe those puzzles educate the Engineer in you, or if you want to finish with a Math degree they can be complementary.

nomemory··on Thirty Seven
One or two years ago I've written a small blog post about the number 37.

Yesterday the traffic on that page exploded. I am sure it's related to the Veritasium movie.

nomemory··on Notes from an Interviewer
1) it's not black and white.

2) English is not my main language, hard to explain, but we use the masculine form when we refer to "the candidate" (which is a masculine noun). Sometimes I do a bad job at translating my thoughts into English and I get to sound like that.

nomemory··on Notes from an Interviewer
I do get your point, but are you under the presumption there are no women metalheads?
nomemory··on Notes from an Interviewer
I get the joke, but it's not like that. We have a few metalheads in the office. They did kill their fair share of dragons in video games.
nomemory··on Notes from an Interviewer
We live in a small country with few decent highschools and universities.
nomemory··on Notes from an Interviewer
Don't worry!
nomemory··on Notes from an Interviewer
I am also doing lots of interviews, and I try to stay away from theoretical questions about SOLID, OOP , the difference between a GET and a POST, what is an inner join, or similar.

Most of the seniors I interviewed were acing questions like this (they probably answered them tens of times before), and there's no way to differentiate them, once you get perfect answers. As the author of blog post mentioned, some of them don't even listen the question till the end before reciting manual phrases about Single Responsibility.

Some people would disagree but for us there are a few factors that predict if the candidate would be a good fit:

* The ability to solve easy and medium leetcode-like challenges and explain his choices. Nothing fancy, no dynamic programming or graph theory. This tells us if the candidate knows how to write code, which in most cases is at least 50% of the job.

* His academical record. It's a good predictor, because people who actually did good in school and finished their homeworks have a good work ethic. Of course, we are not recruiting PHDs to do backend work, but people who did decently well in school are usually nice to work with. There are brilliant dropouts, of course, but they are not the norm.

* We test how opiniated the candidate is when it comes to technology by asking outrageous questions (relative to the Status Quo): Why dependency injection is bad. We like people with opinions, but we find difficult to work with "evangelists".

The rest is commentary (at least in our case).

nomemory··on The seventh most popular easily understood unsolved problem on MathOverflow
In his defense lots of unsolved questions are inscrutable for the majority of people. So this one looks decent.

It was a joke, I know there are lots of people who care about that.

It still boggling we haven't proved the sum of pi + e is irrational. Who cares anyway?
nomemory··on The Sinusoidal Tetris
Game has changed, no it's possible to actually win, if you reduce the signal very close to 0.

There's an indication for a loss and for a win.

There's a turn based mode implemented.

You can get hints for the best sinusoids.

nomemory··on The Sinusoidal Tetris
Implemented 2.

Now there's a turn-based mode so it stops and gives you time to think.

nomemory··on The Sinusoidal Tetris
I've added the feature so you can see the first 4 optimal sinusoids.
nomemory··on Physics for Mathematicians – Introduction
I was more math oriented during my studies, and I hated physics (couldn't openly admit that). I still don't get a lot of the physics I was taught, but I did juggle my way out of it using math, learning some formulas and getting a passing grade. Deep inside I admire physicist more, because for them the things that never clicked for me are natural.

They are rectangular shapes on the canvas.

If I put touch-action: none, the screen is frozen on my Galaxy, and I cannot zoom out to see the canvas.

I've tried touch-action manipulation instead.

Is it working better now?

Congratulations, you've beaten Fourier Tetris.

Author here, I am not a webdev, and I have no idea how to fix that. Do you have any suggestions?
