What about using https for an URL on a security certification...?

A colleague of mine from the administration department suddenly enters my room where my team and me are all busy and, without considering I'm talking with someone else, interrupts us.
he: "I needed to call you but your phone is in do-not-disturb mode"
me: "that's because I'm busy working on something urgent and I don't want to be disturbed"
he: "but I need your help!"
me: "we're working on a urgent thing, but, anyway, what's the problem"
he: "I need help with digital invoicing"
me: "I deal with programming, I don't think I can help..."
he (interrupting): "I created a digital invoice but I need to send a printable version to a customer"
me: "digital invoices should be XML files so you can't simply take the file's content and paste into Word and print..."
he: "in fact that's what I did and the result was horrible"
me: "I was saying just that. I'm sure, anyway, there should be some online tool for producing a well-formatted PDF from a digital invoice"
he doesn't say anything
me: "you can try with a search on Google..."
he: "but I'm not an IT guy, that's not my business"
me: "this has nothing to do with programming, you simply need to find a tool online for doing this"
he (disappointed): "ok, but this is computer stuff, I'll try..."

You know when it's friday and you want to postpone all the non-programming tasks (meetings, calls...) to the next monday... but then suddently monday arrives...!?

You know when you decide to choose a language/framework/platform not because it's the best for the job, or the one with most developers, or the one with most job offers, but simply... because it makes you feel good, even just by looking at the code...!

Last monday I started using a mechanical keyboard at my workplace and now the ones who are in my same room probably want to kill me...! 😉

What to say to a web designer whom you're showing svn to, when he says "it's just like Dropbox"?
