It seems like the natural progression of the Tech Short Takes is moving toward monthly articles, since it’s been about a month since my last one. Redpill Linpro talks to readers about their new routers running Cumulus Linux. This article from Bruce Schneier is worth reading. Both are good articles. Servers/Hardware.
