Alternating Analog/DigitalJanuary 23, 2018
I once heard it described that the universe seems to be viewable through both an "analog"/continuous lens as well as a "digital"/discrete lens. And furthermore, that as you zoom out from the minute, there can be a kind of back-and-forth between analog and digital models making the most sense. It makes me wonder whether computation will evolve in a similar way. Maybe our deep neural nets will evolve into systems that mix and match continuous and discrete layers, giving rise to a synergy between the two that takes its abilities to the next level. That's a pretty raw and not-thought-through idea, but it has a certain ring to it for me... Tech WatchDecember 29, 2017

Vimscript: How to URL Encode a StringJanuary 25, 2017
" URL encode a string. ie. Percent-encode characters as necessary.
function! UrlEncode(string)
let result = ""
let characters = split(a:string, '.\zs')
for character in characters
if character == " "
let result = result . "+"
elseif CharacterRequiresUrlEncoding(character)
let i = 0
while i < strlen(character)
let byte = strpart(character, i, 1)
let decimal = char2nr(byte)
let result = result . "%" . printf("%02x", decimal)
let i += 1
endwhile
else
let result = result . character
endif
endfor
return result
endfunction
" Returns 1 if the given character should be percent-encoded in a URL encoded
" string.
function! CharacterRequiresUrlEncoding(character)
let ascii_code = char2nr(a:character)
if ascii_code >= 48 && ascii_code <= 57
return 0
elseif ascii_code >= 65 && ascii_code <= 90
return 0
elseif ascii_code >= 97 && ascii_code <= 122
return 0
elseif a:character == "-" || a:character == "_" || a:character == "." || a:character == "~"
return 0

return 1
