I've spent the past two days building a box, getting settled into a new user environment, and researching the heck out of some off-site mail problems one of our clients is having. This logical problem-solving part of my brain hasn't gotten a workout like this in years. It also requires a kind of steady focus and constant reassessment of the same set of data in order to solve the problems, a kind of ... I dunno, should I call it skill? Mindset? Heh, see what happens? I spend two days focusing on data interaction, methodology, and highly technical stuff, and all my words fly out the window.
It's good to tax the brain like this again, though. One of the things that's different about this place is that it's all up to me - I'm told what needs to get done, but now how to best go about it, nor offered any advice on how to do things. This isn't ou of neglect, but rather because the boss hired us because we're good at what we do, so we'll figure it out for ourselves. I like it - I like not feeling like I could "punt" any technical problem to one of the other guys, I like being given a difficult issue and tearing it apart bit by bit (and byte by byte...) and finding out how to do it. It's draining, but it's draining like a good footrace is.
Of course, I'm still stymied by some weird rsa/dsa problems with SSH, but I will figure it out, I really will.
(edit to add: it was, it turns out, a problem with permissions on the remote directory, something I had no way of knowing until I was logged in anyway! Problem solved! Man, I learned a lot about SSH today.)
