Come work at Notemeal. We have an office with a private gym in Boston and can get tested for COVID once per week as a perk. https://notemeal.io jokes aside (kind of), we were remot…

I've begun the rationalization process...I should be able to start this sometime in January. I've begun drawing up the plans though...

We did this with the New England Patriots, only we moved to an on-prem PostgreSQL instance. Specifically, we were on Oracle 8, so just finding the compatible drivers was half of th…

As a Software Engineer, I'm looking for a good Introductory/Intermediate level statistics class that would be great for myself, and the rest of my team, to take together. Ideally t…

Trying to verify my identity on Poloniex so I can deposit USD, and happened to have the web developer console open, only to see a host of ERR_CONNECTION_RESET issues. Failed to loa…

This page suggest that I am logged into "VK", which apparently is the Russian-equivalent of Facebook, but I never heard of it before this. Any reason why that is?

I am a programmer trying to learn math, so are my intended audience members. That said, I should include facts related to convergence, and maybe even speed compared to SGD. As to t…
