• MWL ☛ 105: A Fully Patched ShroomOS

  Here’s a tidbit from the backers-only special edition of Networking for System Administrators. All those shrooms were one interconnected, internally networked living thing. Networked. Sort of like computers. Except mushroom networks are efficient.

• Jeff Geerling ☛ Recovering videos from my Sony camera that I stupidly deleted

  Unfortunately, as it was the end of the day yesterday when I got back from a video shoot, I had the folder on the external drive open, and not the folder where I copy the files to on my NAS. Thus, after I thought I had copied all the files to the NAS, I deleted the local folder on my computer. Then I ran the sync command, and apparently I have that sync command set to delete files that don't exist in the source.

  Oops. Just deleted all the new footage. And because I copied to my local Thunderbolt drive, and not my NAS, that hourly snapshot didn't have the new footage.

• Zach Flower ☛ Spinning up an Onion Mirror is Stupid Easy

  Why? Because why not. And also because I can. Oh, and free speech and anti-censorship and all that jazz.

• University of Toronto ☛ Two reasons why Unix traditionally requires mount points to exist

  I think there is one answer for why this is a good idea in general and otherwise complex to do, although you can argue about it, and then a second historical answer based on how mount points were initially implemented.

• Wouter Groeneveld ☛ Is It Worth It To Optimize Images For Your Site?

  Yes but it depends on how you define the verb “to optimize”. For any image conversion heavy lifting I rely on the trusty ImageMagick yet I’ve been wondering whether my argument preset is correct: should it be more or less optimized?

• University of Toronto ☛ We can't really do progressive rollouts of disruptive things

  This means that progressively rolling out a kernel update (and rebooting things) to our important, visible core servers requires multiple people-visible reboots of machines, instead of one big downtime when everything is rebooted. Generally we feel that repeated disruptions are much more annoying and disruptive overall to people; it's better to get the pain of reboot disruptions over all at once. It's also much easier to explain to people, and we don't have to annoy them with repeated notifications that yet another subset of our servers and services will be down for a bit.
