IBM 026 card punch machines and Olivetti teletypes producing blue paper tape where my starting point. Still have some original, unpunched, Fortran Statement cards kept as a souvenir.

During my student days, we wrote a spoof Fortran language proposal to add the COMEFROM statement to replace the much derrided GOTO

Bit late to this discussion but... 1) you have a job that pays you, like academia, or you're a student and you write something that you don't have the time or inclination to turn into a commercial product - 'cos you have a job. 2) you write something in the course of a bigger job, a utility or a library or an interface to some other library (e.g. C++ front end) that has no commercial value in itself and, as others have said, you're happy to share and show off. 3) you've written something that you thought you could make some money from but it was unsuccessful. There is actually quite a bit more to commercial success than just building the better mousetrap. Publishing as open source might yield some crumbs from an otherwise failed adventure. I've done all 3...

Ok, time to lower the tone 'cos this topic recently came up at work and I'm not allowed to do this in the office. Cue Eric Idle ... Penetration Testing? Nudge nudge. Know what I mean. Nods as good as a wink to blind budgerigar. Say no more squire. Say no more. (Nudge Nudge - Monty Python's Flying Circus - YouTube[^]

19 & 20. W10. And yes, I like it.

Yes, you can use WiX and other extensions, such as Laurent Kempe's excellent Git Diff Margin, with VS Community Edition. Note that WiX toolset does not currently appear in Tools/ Extensions and Updates for VS2015 (any edition); it must be downloaded directly from WiX Toolset[^]

Yep. We sell an industrial controller based around the Pi. It's a port of an existing Win32 C++14 application. Used to need a full Win7 system in a rack but now fits in a cigarette packet size box that can be tucked in a corner. No user interface and only dependencies are on Ethernet and USB so pretty much the same code across platforms. Ported to Linux desktop first and then simply a case of recompiling for ARM on the Pi. Running Raspbian Jessie and GCC 4.9.2. Pi 2 Model B is the latest and best specc'ed. Only reason to go with something lesser, like the Zero, would be the lower cost when you're shipping thousands or power consumption running off a battery.
