I don't dumpster dive much more these days, it's not worth the effort.

They ought to know the basics of how a network is put together. Understand vocabulary like router, server, LAN, WAN, ethernet, packet. Not saying they're all going to be future sysadmins, but people who understand how data gets from one place to another definitely have an advantage in today's world.

How often does your PM (also the SM?) re-estimate the stories? I could understand doing that at the end of a sprint, but not in the middle of development, other than "How's that widget coming? I should be done tomorrow."

I work on one of several teams adding features to huge, complex software suite. I don't know how well Agile would work when creating a new application from scratch, but for adding features to an existing program it works really well. The methodology helps us keep a rein on our scope and has greatly improved our interoperability with the other teams. With the goal that a given feature has to be releasable by the end of sprint 4, we're releasing small, working features more often instead of massive, buggy features a couple times a year.

Yes. The recruiters who troll LinkedIn must just search for one specific skill and spam everyone who has it. I always get offers for jobs I'm either not qualified for or would never willingly do.

Last year I realized that I'd never changed my LinkedIn job profile info to "not interested" after starting my new job a year earlier. I'd been getting a lot of pings from recruiters, and I thought that might discourage them. Nope. Saying I wasn't interested made the recruiters even more interested in me!

Which would be great if any of them had a job better than my current one, but they never do. Everything is more boring work I'm less qualified for, for less pay.
