At an insurance company, I encountered an application that had been in place for thirty years. Classic flat-file, mainframe COBOL. And decades old.

I recently refactored some code that takes longs from two different sources to compute one value. The code originally stored the longs and called a function when all of the data arrived.

There have always, it seems, been people for whom attribution and citation really matter. Some of them passionately engage in arguments that last months or years, debating the merits of comma placement in written citations for the work of others. Bizarre, right?

We tried a new retrospective prioritization/voting technique this week that worked really well. After we had generated and discussed all of our ideas for improvement, it was clear to me that there were several excellent ideas and it would be hard to use our regular voting technique to single out one or two.
