Things change, and change is bad.
One bad change you may have noticed is that a handful of the posts here are now password-protected. This isn't something I'm especially happy about, since these posts are about things I think are cool, and which I want to share with everyone. But someone smart (and with a significant stake in the matter) made the case that these posts also leaked information which could put me and others at risk.
I've tried to adopt the most measured response that still fixes the problem: hide only the posts I have to, and put those behind a wall rather than destroy them entirely. While I hope this is the last time I'll have to do this retroactively, we don't always get what we want or expect.
If you see a password-protected article, and have reason to believe I know and trust you, then you can always send email and ask for the password. Unless that trust is already established, though, you're wasting your time -- if it were something I could show to just anybody, I'd already be doing that.
