One time pads. Key distribution is done out of band. For eg: n-th character of prime numbered paragraphs in the book Bleak House by Dickens is the key. True to its name, never reuse the one-time-pad between messages.

How long before GH starts pushing email spam with digests of "Projects that might interest you"? It would be great if they could instead redirect efforts to tie their recommendation engine to their search results. User intent is c

My two cents. Why does this have to be a regulated force-fit? Companies can choose to offer a basic support tier (eg: kb forums, email) and a higher paid support tier or could bundle this as part of their pricing tiers. I don't see why

I am from India and VCRs came into my life in the mid to late 80s. Initially, VCRs were so damn expensive (because they were all imported) and you would rent them for a weekend and a few films. The whole family, friends and neighbors would

Yes. You need to select one piece from each row. Selections in different rows cannot have an O and X of the same color. If you think of this in terms of 3-SAT, the O's are positive literals (like a, b, c etc.,) and X's are negativ

Cool. I have thought about the same thing a while ago, but held back. The code gen you are talking about is for data wrangling and shaping, right? I used ML.net from MSFT and it comes with an ONNX runtime that is quite easy to use, esp if w
