Thoughts on how to show a server-side CET time as CET in a JS client no matter which time zone the browser has.

Option 1: send strings in the API

API changes:

item:
  ends_at_string: "4 maj kl. 12:31 CET"
  bids:
    - timestamp_string_short: "4 maj kl. 12:31"
    - timestamp_string_long: "4 maj 2015 kl. 12:31 CET"

Overwrite `t` helper in Rails views to raise in tests, which it otherwise doesn't do, even if I18n is configured to.

An awful hack (not cleaned up) to programmatically rename events (adding number prefixes to follow a certain schema) in iPhoto even though it doesn't seem to support that via AppleScript. Exploiting the convenient keyboard shortcuts.
NUMBER = DATA.readlines.inject({}) { |h, line|
number, name = line.chop.split(". ", 2)
h[number] = name
h
}
def osascript(cmd)
system "osascript", "-e", cmd

Stick this in the lib directory and use it instead of SimpleDelegator to solve this issue: http://thepugautomatic.com/2014/03/simpledelegator-autoloading-issues-with-rails/

Teknisk skuld (Henrik Kniberg, Crisp)

  • Definition of Done kan säga "no added technical debt"
  • Definition of Done kan t.o.m. säga "less technical debt"
  • Notera tillfällig skuld i en debt backlog och betala av den enligt någon princip, t.ex. 80 % nyutveckling och 20 % betala av skuld
  • En kreativ röra är okej kortsiktigt (jfr. stökigt kök i matlagning)
