Storage changing software, what makes Unix special, what you need may be “pipeline +Unix commands”, running a bakery on Emacs and PostgreSQL, the ultimate guide to memorable tech talks, light-weight contexts, and more. ##Headlines ###Tracking a storage issue led to software change Early last year we completed a massive migration that moved our customers’ hosting data off of a legacy datacenter (that we called FR-SD2) onto several new datacenters (that we call FR-SD3, FR-SD5, and FR-SD6) with much more modern, up-to-date infrastructure. This migration required several changes in both the software and hardware we use, including switching the operating system on our storage units to FreeBSD. Currently, we use the NFS protocol to provide storage and export the filesystems on Simple Hosting, our web hosting service, and the FreeBSD kernel includes an NFS server for just this purpose.
