in C Plus Plus, ruby, startup

oh no, I just updated a ruby gem!

Are you a ruby developer? Do you want to manufacturer something to do? Well here is a quick tip. Take your beautiful working Rails 3 application that you started creating 6 months ago and type in “bundle update”.

I don’t think there exists a time when I have issued that command and then 10 seconds after it completed not thought “what the fuck was I thinking”. Just about every gem that updates seems to make several breaking changes. For real comedy value it’s worth doing it between major Rails releases, actually, I take that back, make that minor Rails releases.

This just doesn’t seem to happen with C++ libraries. When coding in C++ (which I do almost every day) I can reliably update to even major version changes and still be pretty much guaranteed that what worked before will still be working now. At most you get a “deprecation” warning. Not in the Ruby world, oh no, here progress is rapid but backwards compatibility is an afterthought. It really is no wonder that enterprises are so cagey about moving to, how can we say it, well in the words of Steve Yegge, hardcore liberal languages. There is something to be said for stability.

So is this a bad thing? As much as I would like to say that I think it is, I’m just not that sure. There is nothing more frustrating than using something that is not willing to change (I’m looking squarely at you Java). It’s the fact that there is no attempt to maintain backwards compatibility for at least a short period of time that doesn’t fill me with confidence.

These days you see many people picking the latest and greatest technology to build a business on. This always makes me squirm just a little. This may be OK for a small business with technical founders. However, it makes little sense for a company with shareholders where employees can leave at any time. I certainly wouldn’t want a company I’d invested my money in being in left open to the vagaries of change quite so much.
