hmartiniano··on Splash-free urinals: Design through physics and differential equations
Thanks, I wasn't aware of this. It was jut the first thing that popped into my mind when I read the title. I wasn't the only one, apparently :)

Someone please nominate this for the Ig Nobel Prize.
hmartiniano··on Flexible use of a multi-purpose tool by a cow
Someone should nominate the authors for an ig Nobel prize.
hmartiniano··on Prosperity comes at 'devastating' cost to nature
Here's the link to the actual document the article is about:

hmartiniano··on Ryanair, Hamiltonian Cycles, and using graph theory to find cheap flights (2018)
The second phrase of your response contradicts the first. :)
hmartiniano··on France has approved a digital services tax despite threats of retaliation by US
What I was arguing is that raising taxes revenues instead of profits (when companies declare no profits as part of tax-avoidance schemes) will eventually make them declare and pay taxes on real profits.

You have a point here, but what really is at stake here is tax-evasion, not reduction.

The company declares no profits in France (and thus pays no tax) because its profit is fraudulently passed as costs to pay for IP or services for the mother company in another country.

Which is actually a good idea: increase tax on revenues for companies using tax-evasion schemes until it is no longuer profitable for them to continue doing so.

Also, consider the fact that tax evasion is a crime in most countries and that this is a very bland measure when compared to what these companies (and their executives) really reserve.

It looks like you're right:

hmartiniano··on AlphaFold: Using AI for scientific discovery
You're absolutely right. My bad, mixed too many ideas at once :). Gradient descent (or similar techniques) can be used for structural optimization with the same atomistic models used in molecular dynamics.
hmartiniano··on AlphaFold: Using AI for scientific discovery
I'm not really "in the field" but I did some computational work on protein folding in the past.

I have a hunch on how they are doing this.

From the blog post it appears that the network is using angles and distances of aminoacids in a given sequence in know structures to predict good starting point(s) for regular molecular dynamics-based structural optimization (what is called the "gradient descent step" in the post).

If I'm wrong then I'll just have to try this approach myself one day...

hmartiniano··on Relax – A New Generation CMS on Top of React, Redux, and GraphQL
Lektor (https://www.getlektor.com/) might be a good candidate for that. It has a graphical user interface which makes editing accessible for non technical folks.
hmartiniano··on We Need a Better PC
I also own one and can second all you say about it. The only problem is the lack of a backlit keyboard, which might be a show stopper for some people. Other than that it's a very good machine, at a very good price and installing Linux (at least ubuntu, from my experience) is absolutely painless.
hmartiniano··on How to get rich in tech
Despite beeing more expensive (think double or triple the 500$ figure for a comfortable life, depending on the particular country you choose), south european countries might be a good alternative. You get more stability and much better education and health systems, while keeping the good weather and lower cost of living.
hmartiniano··on Why the Internet Needs IPFS

Or the other way around...
