Tails above the Rest, Part III
One of the final security tools included with Tails makes the most sense if you happen to have the persistent disk enabled. KeePassX allows you to keep track of user names and passwords securely for any accounts you may have within a single encrypted file. The idea here is that you can pick a single, secure password that you can remember to decrypt this database. You can choose really difficult passwords (or have KeepassX generate random passwords for you based on character sets and lengths that you configure) and have KeepassX load the password into your clipboard so you can paste it into a login prompt without even seeing it.
To launch KeePassX, click Applications→Accessories→KeePassX, and click File→New Database to create a brand-new password database. If you are using a persistent disk, be sure you store the password database within the Persistent folder. The password database is protected by a passphrase, so select a nice secure password that you can remember for this database. Once the database is open, you then can select the appropriate category for your password and create new entries for each account. Once you are done and close KeePassX, if you didn't remember to save your changes, it will prompt you before it closes.
Hopefully you now are well on your way to secure, anonymous Internet use. The nice thing about Tails is that it's simple enough to use that you can share Tails disks with friends who may not be all that familiar with security and know they will gain an extra level of protection. Although this is the last column in my Tails series, you can expect more columns about security and privacy from me in the future.

Practical Task Scheduling Deployment
July 20, 2016 12:00 pm CDT
One of the best things about the UNIX environment (aside from being stable and efficient) is the vast array of software tools available to help you do your job. Traditionally, a UNIX tool does only one thing, but does that one thing very well. For example, grep is very easy to use and can search vast amounts of data quickly. The find tool can find a particular file or files based on all kinds of criteria. It's pretty easy to string these tools together to build even more powerful tools, such as a tool that finds all of the .log files in the /home directory and searches each one for a particular entry. This erector-set mentality allows UNIX system administrators to seem to always have the right tool for the job.
Cron traditionally has been considered another such a tool for job scheduling, but is it enough? This webinar considers that very question. The first part builds on a previous Geek Guide, Beyond Cron, and briefly describes how to know when it might be time to consider upgrading your job scheduling infrastructure. The second part presents an actual planning and implementation framework.
