WP-Cli Tutorial – How to Use WP-Cli with Your WordPress Site – WP-Cli is a command line interface which allows the users to manage their WordPress web sites from the command prompt. Upgrades can be performed, backups can be generated, new posts can be published and most of the regular admin actions can be performed with a set of commands. In this tutorial we will explain how to use the WP command line interface in order to complete regular administrative tasks like upgrades, database backup creation, plugins and themes installations and removals, publishing and deleting posts, changing site's URL settings and getting help on chosen commands. Note that WP-Cli requires an SSH access.
debsecan – The debsecan program evaluates the security status of a host running the Debian operation system. It reports missing security updates and known vulnerabilities in the programs which are installed on the host. debsecan accesses the dpkg database and obtains a list of installed packages and their versions. This list is then evaluated against a feed of vulnerability information which ultimately comes from a database maintained by Debian's Testing Security Team . Various output formats are supported, including incremental reporting via email. Beginning with version 0.2, debsecan includes a script called debsecan-create-cron, which allows you to create a cron job which periodically sends you mail (once per day) when the security status of the system changes.
Barriers, Caches, Filesystems | monolight – With the recent proliferation of ext4 as the new “default” Linux filesystem there’s been much talk of write barrier support. The flurry of post-2.6.18 barrier related development in most storage subsystems has left some novice users and administrators perplexed. I hope I can clear it up a bit with this primer/refresher.
SMTP, testing via Telnet – FreeBSDwiki – When troubleshooting problems with SMTP service – your own, or others – it is frequently very helpful to be able to "speak" to the SMTP server directly, rather than going through a mail client which won't necessarily tell you exactly what the SMTP server is saying. You can easily do this with the telnet client. Note that many ISPs do not allow outbound connections on port 25 to any SMTP server but their own – if you get timeouts when trying to connect to port 25, you should try port 587, which is the standard ESMTP port. (Port 587 connections normally require SMTP AUTH, which is covered below.)
These are my links for 4 set 2014 through 5 set 2014:
tmux-plugins/tmux-resurrect – Restore tmux environment after a system restart. Tmux is great, except when you have to restart the computer. You lose all the running programs, working directories, pane layouts etc. There are helpful management tools out there, but they require initial configuration and continuous updates as your workflow evolves or you start new projects. tmux-resurrect saves all the little details from your tmux environment so it can be completely restored after a system restart (or when you feel like it). No configuration is required. You should feel like you never quit tmux. http://undeadly.org/cgi?action=article&sid=20140904174329
