  • College professor here: we’ve all seen a major decline in social skills over the last 4+ years, rather sudden and precipitous, so clearly not just the “normal” changes we’d been seeing over the previous two decades. Loss of basic functionality is the most glaring, like students who simply cannot bring themselves to talk to a professor face-to-face, or speak in class, or make a phone call, or make a decision about their own education, etc. etc.

    The most glaring last fall was an entire class of mine that would arrive early and sit in the dark…despite my explaining how to turn on the lights (i.e. the wall switch by the door). When pressed they collectively said they were “afraid they’d get in trouble” for turning on the lights (despite my telling them to do so) and were afraid to “do anything that would draw attention to them” like being the one person to turned on the lights. So next month with my next group of freshmen we’re going to have a talk about basic life skills on day one, starting with turning on the classroom lights when they arrive.
















  • When I bought them 2 years ago power in MA was $0.46 per kWh, this included transmission costs and all the other fees. 15W cost me $4.80 a month, so $57.6 a year and $230 over 4 years. At the time 14TB mechanical disks were about $300 so it was about a $270 ‘premium’ for solid state over mechanical so I exaggerated the ROI, but to me the 2x price premium was worth it for silence and no latency on retrieving my data. So in summary the ROI for me was more like 8 years, ignoring the many advantages of SSD.
