breaking (n)vim changes

overview over the course of the past year i’ve more or less been forced to move off of emacs and onto nvim. the positive impact on my fingers and hands has been huge. but the retraining of years of muscle memory has been more than a little painful. i’m still getting my vim mojo, but i think i’m more or less 80% as productive as i was previously. recently, i noticed that with the move to nvim 0....

10 years of RIPE probing

i got this little gem of a reminder from the folks at RIPE this morning. i suspect that actual uptime has been a bit better than noted, but i haven’t been the most rigorous about keeping the lab/monitoring segment online over the years. this covers connectivity through comcast, centurylink/qwest and USI over the past 10 years. it also includes stints at cisco (partially), juniper, palo alto networks and arista. a lot’s happened over the past 10 years....

the trivialization of TED into a religion

this article hit pretty close to home this weekend when the TED radio hour came on and i had to ask alexa to shut it down because i couldn’t take the breathless delivery of the presenter spouting TED cliches. the tl;dr - TED’s about to become as vacuous as any other religion; titillating the senses and delivering pablum. the author doesn’t call it out in this manner. but they do a nice job of pointing out that TED’s veered into the trivializatin of things and the presentation of real problems as “puzzles to be solved....
