  1. Pretty slick looking deployment service. Automated or manual. Free for 1 repo, $15/month for 10 repos. Was dploy.io, now rebranded.
  2. privbind runs an application as an unprivileged user after binding it to a privileged port. Great for running node on 80 for example...
  3. Salt is a little like Ansible I guess, new alternative to puppet|chef, neat, built on python, open source.
  4. Ansible looks like a newer, simpler puppet|chef. Uses ssh by default, which is pretty neat, well suited to things like ec2, getting machines up from the ground up. Python. Smart. Free.
  5. To fix SSH agent forwarding, set the $SSH_AUTH_SOCK value. I copied it from my first login into my screen session and it worked fine. :-)
  6. Handy little script to monitor varnish stats from zabbix. Awesome.
  7. Explains how to fix putty so it plays nicely with byobu. Requires two settings, Windows > Translation > UTF8, and Terminal > Keyboard > XTerm R6. Haven't been able to verify, but reports suggest it works.
  8. Yet another monitoring app. Copper Egg combines real user monitoring, generic metric logging, server monitoring and maybe other stuff(?) into one application. Pricing starts at $19/month. Not unreasonable.
  9. Really detailed tool that diagnoses in great detail each step of the DNS resolution process for a domain. Free and invaluable.
  10. A zabbix monitoring script for varnish ported from cacti.
  11. Useful forum post that explains the `top -b` option, making top output text suitable for piping / writing to file, like `top -bn1 | mail`...
  12. A free hosted version of the open source monit-aggregator written by Matt Fawcett. Appears to be free with no node restriction.
  13. Source code of monit-aggregator by Matt Fawcett / runslikeclockwork.com. He offers a free hosted version at that site.
  14. Takes alerts from monitoring systems and sends emails, phone calls and SMS messages. Handles on-call schedules, escalation, acknowledgement, etc.
  15. Article explaining how to set a scheduler on linux. Handy. :)
  16. A guide on how to get the most of out the linux top utility. Includes a description of the column names, and other tips & tricks.
