Turnkey Linux turns everything up to 12 on their 4th B-Day…

The guys over at Turnkey Linux have released version 12 of their awesome server appliance core platform.  They also added 60+ new appliances.  If you haven’t given them a shot I highly suggest it especially if you are new to Linux.  Heck I am an old time Linux user and love the ability to just download an appliance like the one they that comes setup with the Redmine project management server and Git, Bazaar, Mercurial and Subversion SCM.  Everyone of them is setup and ready for you to use.  Just download the appliance in any of 7 formats from ISO images to OpenVZ VMs and so much in between.  The best feature I have come to love and rely on is their server back and migration tool.  They call it TKLBAM – AKA the TurnKey Linux Backup and Migration system.  It allows you to take any currently existing system and back it up to S3.  Then restore the backup to a new machine leaving you in the same state but on updated software.  All the benefits but none of the pain.  It’s an awesome idea and works well.  Watch for a full review and description of my experience coming soon. 

One really import change is their migration away from Ubuntu to Debian.  Check out the article for a very clear description and explanation of why.  The reasons are sound and hopefully the right people are listening.

Most of all though we would like to wish them a Happy 4th B-Day.  Let’s hope there are plenty more in their future.

Do you want to Hangout and Talk GIT and Linux?

Git It On Tuesday, March 27 at 9pm EST

The Crew and I will be joining up with Mike Jansen in a Google+ Hangout right after we record the next podcast.  We plan to discuss git, linux, and other related topics.  We look forward to seeing as many of you as possible.  So come on over there and join us.

This is informal and all are welcome to join. If you have any specific topics you’d like to discuss, comment on this post.

Are two monitors really needed?

In and article over at Datamation the answer seemed to be that it depends on the person and the job maybe.  If you are a developer there is evidence that you can improve your effectiveness by twenty to thirty percent with a second screen.  While this article isn’t very scientific it does give those in operations or management a nice insight into what people are thinking.  It does make for interesting question about whether developers should have laptops.  Check it out and see what you think.

What’s the next big trend in fast development?

Well a developer in Melbourne is proving out that it might just be Django which is built on Python.  We at Linuxinstall.net are big fans of both technologies.  They are extremely empowering espeically for those less developer focused on administration teams.  The interview here though talks about how he came to choose it and links to several example sites and the several of the projects discussed.  Check it out here.

Check your Apache server status remotely…

Don’t want to login via SSH to check on an Apache Web Server?  This article explains how to setup the server status page.  One word of warning though.  This page is turned off by default for a reason.  It can be used by bad guys to determine all kinds of things about your server and makes you more vulnerable.  If as the article suggests you restrict the IP addresses you can partially mitigate it.  The best way to handle it is not to expose it to the internet at all.  Unfortunately if you are hosting remotely, like at Amazon Ec3 or Server Beach, you may have to use an SSH tunnel to secure it.  You could restrict it to an IP Address but remember that IP Addresses can be spoofed.

Ever wondered how Facebook handles half a billion people a month?

Check out this other keynote from OSCON by David Recordon.  Who is David? From his Bio on his Web Site.

“David Recordon is the Senior Open Programs Manager at Facebook, where he leads open source and open standards initiatives. He joined Facebook from Six Apart where he focused on platform strategies, and previously worked at VeriSign in the emerging business group. David has played a pivotal role in the development and popularization of key social media technologies, such as OpenID and OAuth.”

It’s pretty high level but the numbers are impressive.  Today they are taking in between 80 and 90 TB of data a day.  In 2008 they only took in about 1.2 TB.  Check it out for a cool insight that isn’t focused on the privacy issues they are dealing with but the real nuts and bolts technology and how most of it, if not all of it, is Open Source.  On the Facebook Web Site there is even a whole page dedicated to the Open Source they use, support, created and released.
