when you learn a programing language, do you watch video lecture/presentation?
and, programers, eat walnuts, live forever. Buy at amazon you buy, you eat, i live. Yes it's an ad. out of my own volition.
ML stands for?
when i see the abbreviation ML, i think of Meta Language, the grand daddy of SML, CaML, OCaML, FSharp, Clean, Miranda, Haskell. ML were invented for automated theorem proving. Machine learning?? you mean like smart guessing?
brave browser still have the bug, where sometimes the url field shows the url from a different tab

new book. The Little Typer
new book. The Little Typer Buy at amazon 2018, By Daniel Friedman et al.
Friedman is one of the top lang researcher. He's 74 now. So am not sure he's actually the main author.
Friedman wrote a series of books titled “Little Schemer”, “Little Java”, “Little Prover”, “Little MLer” etc. Daniel P Friedman Books I read Little Java back in 2000. Wasn't comprehensible to me. I never liked these story-telling style books.
why not perl6?

typed vs untyped lang
now am of the opinion that programing languages should be typed. (modern system, eg golang. not C, C++, Java). When younger, i thought it should not, cuz i considered typing as by-product of compiler.
in some sense, typing is a unwanted by-product of computer engineering aka compiler. and, it was so, up to 2000. However, with different perspective, a proper type system, is like a good property of logic system. For programing language, it improves correctness, bring clarity.
there are exceptions. e.g. Mathematica (aka wolfram lang), where the computation model mostly is a symbolic term rewriting system. So, typing system does not apply. (btw, lisp is almost the same, except lispers since 1990 are extreme idiots. they r C coders in paren clothing.)
disqus ad spamChinese abacus. they have 2 beads on top, 5 below. i never learned their exact function of the “extra” beads. In Taiwan, we grew up with Japanese style, 1 on top, 4 at bottom.

but apparently, the 2 5 setup allows computation with hexadecimal, which is a traditional chinese weight system.
interesting that D lang is still going. “Alexandrescu (i think he's 2nd in D language dev) worked as a research scientist at Facebook, before departing the company in August 2015 in order to focus on developing the D programming language.”
google shutting down google plus
google shutting down google plus, over the next 10 months.
since google began Google Plus in 2011, i'd say it marks the year google goes evil. then, its worse and worse, starting with greed, to now heavy censorship and explicit and blatant political gaming.
a great sadness to witness google over the decades. we helped google succeed back in 2000, since it was the company that does no evil, different from all others.

stupid ipad. i have a old ipad. when viewing some page , requiring 100+ pushes to scroll down. Is there a way to drag the scroll bar?
on android, when u swipe fast, the page flies like on wheels. On iPad iOS, it's like stuck in some viscous shet. i think iOS UI is idiotic.
