Knuth's Art of Computer Programming, V 4B, has gone into print
(I'm still looking for the catchiest way to appreciate the number MMXXVI. Exercise 7.2.1.6–122 gives 1234+.5*6+789 and -1+2345*6/7+8+9 and 1+(2/3)*45*67.8-9 ; other suggestions are welcome.

While I was leading PKC’s security practice, we did probably 20-30 code security audits, almost of all of them for startups that were just around their Series A or B (that was usually when they had cash and realized that it’d be good to take a deeper look at their security, after the do-or-die focus on product market…

A Linux Evening
I love to have Linux as my main OS. For someone who spends most of his time programming, writing HTML, writing LaTeX, and browsing the net, it is nearly a perfect tool. Packages are one "apt install" away. Mounting my website is one sshfs away and with private key authentication I don't even have to type my password…
