Lithium-ion battery inventor John B. Goodenough has responded to questions submitted by Slashdot readers. Read on for his answers.
The original submission asks two related questions. First, "Do you have to be a CS/math genius to make sense of Scala and use it correctly?" But more importantly, "Is Scala there to stay wherever it is deployed and used in real-world scenarios, or are there pitfalls and cracks showing up that would deter you from using Scala once again?" So share your experiences and answers in the comments. Would you recommend moving from Java to Scala?
They heavily penalize your ideal audience, people that use real random password generators. Hey, guess what, that password randomly didn't have a number or symbol in it. I just double checked my math textbook, and yep, it's possible. I'm pretty sure.
They frustrate average users, who then become uncooperative and use "creative" workarounds that make their passwords less secure.
Are often wrong, in the sense that they are grossly incomplete and/or insane.
Seriously, for the love of God, stop with this arbitrary password rule nonsense already. If you won't take my word for it, read this 2016 NIST password rules recommendation. It's right there, "no composition rules". However, I do see one error, it should have said "no bullshit composition rules". What do you think?
In other news, Crockford also proposed ending the "spaces vs. tabs" debate by simply eliminating tabs altogether.
By Saturday, the AI had amassed a lead of $693,531 after 56,732 hands in the 120,000-hand match (which is being livestreamed by the Rivers Casino on Twitch). "I'm feeling good," said Tuomas Sandholm, the computer science professor at Carnegie Mellon who co-created the AI. "The algorithms are performing great. They're better at solving strategy ahead of time, better at driving strategy during play and better at improving strategy on the fly."
You can have a sneak preview by looking at the current draft of pre-fascicle 5a (52 pages), last updated 18 January 2017. As usual, rewards will be given to whoever is first to find and report errors or to make valuable suggestions. I'm particularly interested in receiving feedback about the exercises (of which there are 125) and their answers (of which there are 125).
Over the years Knuth gave out over $20,000 in rewards, though most people didn't cash his highly-coveted "hexadecimal checks", and in 2008 Knuth switched to honorary "hexadecimal certificates". In 2014 Knuth complained about the "dumbing down" of computer science history, and his standards remain high. In his most-recent update, 79-year-old Knuth reminds readers that "There's stuff in here that isn't in Wikipedia yet!"
