      Yesterday the current Irish president, Michael D. Higgins, signaled that he's going to run for another term. He'll probably be unopposed, with broad support, and no election needed. If you're not Irish, allow me to blow your mind with the state of Irish politics ...

      Unpopular opinion: to really make it as a senior/lead engineer, you have to get good at soaking up interruptions, only managing or minimizing them for others not yourself. You just have to adapt to working productively in smaller time slices and handling context switches. Tough!

          Hopefully 2019 will be better! One thought on tweet threads before I close out the year. Occasionally I get "this should be in a blog" complaints. But these tweets have reached an audience of millions of impressions. It's a very effective medium IMO!
