Last week one of our programs failed looking up an airplane by its registration. That’s not a surprise, since ac regs are a horrible identifier. They change all the time. Also there is almost no naming rule at all. Wikipedia states
When painted on the fuselage, the prefix and suffix are usually separated by a dash (for example,
YR-BMA). When entered in a flight plan, the dash is omitted (for example,
YRBMA). In some countries that use a number suffix rather than letters, like the United States (
N), South Korea (
HL), and Japan (
JA), the prefix and suffix are connected without a dash.
TL;DR: You don’t. We eventually gave up on it.
My personal lessons-learned:
Being the IT-guy aka personal first-level-support™ for way more people than I am comfortable with, I have held quite a few mobile phones in my hand and stared into the abyss that is their home screen. The home screen is the modern view into someone’s soul. In a post-privacy-world it is probably one of the most private things we have, since it is utterly worthless to someone who does not interact with it on an hourly basis and has grown to live with whatever way the apps are scattered around the screen.
Since I bought my personal domain name around 2003, I went through several web-solutions, using static html pages, php pages, a custom designed php cms, finally Wordpress and now, as of yesterday, I am back to static html. The 2016-flavour however, which is another attempt of separation of presentation and content (a concept I highly endorse as a LaTeX user).
