rmujica··on A Polynomial Time Algorithm for 3SAT (P=NP?!)
Abstract:

> By creating new concepts and methods—the checking tree, long unit path, direct contradiction unit pair, indirect contradiction unit pair, additional contradiction unit pair, two-unit layer and three-unit layer—we successfully transform solving a 3SAT problem to solving 2SAT problems in polynomial time.

> Each time, we add only one layer of the three-unit layers to the two-unit layers to calculate 2SAT paths, respectively.

> The key is as follows: in each 2SAT path, any two units cannot be a direct contradiction unit pair and cannot be an indirect contradiction unit pair and additional contradiction unit pair.

> This guarantees that all of the 2SAT paths we got, respectively, can shape at least one long path without contradictions.

> Thus, we proved that NP = P.

rmujica··on Atlas, a hopefully better engineering IDE
It seems kind of MathCAD

rmujica··on How this Ends
30 year fixed rate is quite common in Chile, and the mortgage and housing industry is fully deregulated here
rmujica··on The Sweatbox (banned Disney documentary)
I hope the title is not too clickbait-y (it is the original video title), but I think it is a very interesting documentary about a movie that almost didn't came to be and how they turned it around into a franchise and critical success.
rmujica··on Philosophy of the GNU Project (2018)
If it wasn't for the social movement, it might be the computer (and those who make the computer work) the one using you.
rmujica··on How we built scalable spatial indexing in CockroachDB
I've used both approaches, GiST in PG and S2 in Mongo, and I feel that S2 has given me more tools to do queries like "which polygons contain this single point?" efficiently in my use case.

TIL. What for?
rmujica··on Salesforce Signs Definitive Agreement to Acquire Slack
Making an MMO is an incredibly hard but rewarding endeavor. There are so many subsystems that you can design and program that you will never end the game; but you will end much wiser.

It is now affecting ECS and EKS. Having problems scaling own nodes.
rmujica··on Welcome to the Old Internet Again
Tucows!!!!! my ISP (Telsur) had a mirror of most Tucows downloads, so it was very fast to get the newest shareware :)

Oh, those were the days.

rmujica··on Data from Experian breach found on the internet
I think it could be more precisely defined as: the value of any copiable and spreadable asset is inverse proportional to the amount of available copies
rmujica··on A Software Engineer’s Guide to Cybernetics
For some arcane reason, my CS degree had a course in Cybernetics and Systems Theory (which is weird because it is not taught in any other degree in my country, and it is taught by one professor that happened to study Cybernetics in the 60s in East Germany). It is possibly the one course that changed my perception about things, interactions and feedback loops, and it still piques my curiosity.

Wise words spoken before me:

rmujica··on Filing Your Taxes Is an Expensive Time Sink. That’s Not an Accident
I'm Chilean. It just took me ~40 seconds to complete my tax declaration, skimmed through all companies involved (employer, banks and pension fund), typed in my bank account for my tax return and done.
