TechSource Site/Personal Update (2-23-2011) Posted: 25 Feb 2011 03:08 PM PST It has been about a year since I last posted here a personal or site-related update. I believe my last personal note was when I changed the name and design of this site. So why am I doing this now? First of all, I would like to thank our loyal subscribers/readers who truly appreciate the content or entries of this site. Although, I have to admit that it has not been as electric around here as it used to be, many of you remained die-hard followers. You are one of the main reasons why I'm still here and going to continue striving to give you valuable and interesting posts as much as I can. As some of you may know, I have been promoting Linux and other free and open-source software through my writings for more than 3 years already. When I first started, Ubuntu was not yet as dominant as it is right now, and openSUSE was still my preferred Linux distribution. Back then, I had a lot of free time that I could try different distros and write several reviews (see my Linux distribution reviews) per week. It didn't feel like hard work to me since I had (still have) a real passion for Linux and FOSS and truly believe in the importance of free and open source software. My enthusiasm was so strong that sometimes I couldn't believe I wrote and posted the following articles: * Life Lessons Learned From Using Linux * The Advantages of Using Linux * 30 (Corny) Reasons Why I Love Linux * Why Your Mother Wants You to Use Linux * How to Make Windows Faster than Linux * 5 Reasons Why Microsoft is Afraid of Linux * What does Michael Phelps have in common with Linus Torvalds? * We Don't Need Another Linux Hater Although I still use Linux and FOSS most of the time, my energy has waned a bit. Not because I have 'turned to the dark side of the force' but because I'm now doing other new and exciting stuff that I find equally important to evangelizing people on the importance of using FOSS. I hope you get my point. Another reason why I'm inspired to keep this site going is because the site traffic is steadily increasing. Earnings from advertisements are also better than ever. Because of this, I decided to use some of our advertisement income to help take this site to a whole new level. Today, I would like to announce that we are hiring. The requirement is quite simple: Anyone who can turn their passion for Linux and FOSS into creating quality and well-written articles is invited to apply and CONTACT ME. This doesn't mean that I will completely stop writing here. The good thing about having some co-writers around is that it will give me a much-needed breathing space and will allow me to focus on giving you quality content. Hopefully, you will keep on following me and support our soon-to-be contributors. Thank you and have a nice day!

Installing Apache2 With PHP5 And MySQL Support On Debian Squeeze (LAMP)
=======================================================================

LAMP is short for Linux, Apache, MySQL, PHP. This tutorial shows how you can install an Apache2 webserver on a Debian Squeeze server with PHP5 support (mod_php) and MySQL support.

You can find the document here:
-------------------------------
http://www.howtoforge.com/installing-apache2-with-php5-and-mysql-support-on-debian-squeeze-lamp

Nagios Installation On Ubuntu 10.04 (Lucid Lynx)
================================================

This tutorial shows how to set up Ubuntu Lucid Lynx (10.4) server with the Nagios Monitoring System. Nagios is a powerful, highly configurable monitoring and alarming system, which can monitor a wide variety of systems (network, server, daemons, applications). Monitoring could be done for instance for availability or utilization. The monitoring could be restricted to services which are connectable from the outside (e.g. a webserver on port 80/tcp), or with the help of NRPE (Nagios Remote Plugin Executor) plugins for testing could also be executed remote. We will be installing Nagios, Nagios Plugins, and Postfix with this tutorial. Postfix will be configured to send email via your alternate email server. This tutorial will only give you the basic configuration with Postfix, any additional settings can be found in multiple places on the Internet.

You can find the document here:

How To Install Railo 3.2 Under OpenSUSE 11.3 Running Apache2 Tomcat 6 Virtual Host
==================================================================================

Railo Server 3.2 Final (3.2.1.000) has been released. As you know Railo is an Open Source ColdFusion Markup Language (CFML) engine. It is free and pretty fast. For the new 3.2 version railo stops running resin, but tomcat as the default web server. Instead of compiling apache2 with tomcat 6 by yourself, the railo team had created the default installation script which helps you set up railo on tomcat6 and using apache2 to connect to tomcat via mod_jk. Instead of using tomcat default webapps directory, we will modify the server.xml file and DocumentRoot will point back to default apache DocumentRoot directory defined under the virtual host configuration file.

You can find the document here:
-------------------------------
http://www.howtoforge.com/how-to-install-railo-3.2-under-opensuse-11.3-running-apache2-tomcat6-virtual-host

Installation Of PlaySMS And SMS Server Tools 3 On Debian Server
===============================================================

This tutorial will show you how you can set up an SMS server on Debian with playsms and smstools. In my example I have used an old Nokia 5140i with a USB datacable.

How To Compile Coloured rTorrent From SVN In Ubuntu 10.10 Maverick Meerkat / Debian 6 Squeeze With ruTorrent
============================================================================================================

rTorrent is a popular command line based bittorrent client. It provides very powerful features yet it is very light on the system - contrary to other bittorrent clients like Vuze. There are a couple of webinterfaces for it but they are not truly need. SSH access combined with the "screen" program provide you all the tools you need. In addition to the previous compilation guides of rTorrent, this one will also feature ruTorrent on a force Apache SSL connection with password protection.

Live Performance Monitor for Your MySQL Server Posted: 22 Feb 2011 09:01 PM PST If you are a Linux system administrator or have a Linux server running a LAMP stack, you might want to be able to keep an eye on the different elements that contribute to keeping your applications and websites alive. This would include your web server, database server, the operating system itself, among other things. Let's take a look at how you can monitor the performance of your MySQL server using Mytop, a free and open source network/server monitoring software. Mytop is a clone of the popular UNIX application, 'top'. The Installation: On Red Hat Linux based systems such as Fedora you can execute the command "# yum -y install mytop". For Ubuntu Linux users you can just execute the standard "# sudo apt-get install mytop". Jeremy Zawodny, the project's author, also has a source release if you can't find the binary version for your distribution. You can find it at the Mytop protect page at http://jeremy.zawodny.com/mysql/mytop/. Running Mytop: The simplest way to run Mytop is to execute the command directly from the command line interface. Execute the command "# mytop". This may not work if you have a password for your MySQL users, which is a very good idea. In such a case execute the command "# mytop -u username -p[password] -h hostname". Replace the username, [password], and hostname fields with the respective settings on your computer. This would look like "# mytop -u calvin -ph0bb3s -h 192.168.0.25". You will get an output that would look something like the following: MySQL on hobbes03 (5.0.37) up 50+17:53:46 [13:20:38] Queries: 2.5G qps: 609 Slow: 0.0 Se/In/Up/De(%): 01/00/00/00 Key Efficiency: 99.8% Bps in/out: 0.0/ 0.0 Id User Host/IP DB Time Cmd Query or State — —- ——- — —- — ———- 9570443 dbuser 192.168.10.9 appdb 0 Prepar 9575575 dbuser 192.168.10.9 appdb 0 Sleep 9576920 dbuser 192.168.10.9 appdb 0 Sleep 9593343 dbuser 192.168.10.4 appdb 0 Sleep 9601720 dbuser 192.168.10.3 appdb 0 Query show full process 9574728 dbuser 192.168.10.9 appdb 1 Sleep 9575771 dbuser 192.168.10.9 appdb 1 Sleep 9579103 dbuser 192.168.10.9 appdb 1 Sleep 9579962 dbuser 192.168.10.4 appdb 1 Sleep 9581070 dbuser 192.168.10.4 appdb 1 Sleep 9585516 dbuser 192.168.10.4 appdb 1 Sleep 9585518 dbuser 192.168.10.4 appdb 1 Sleep 9597503 dbuser 192.168.10.4 appdb 1 Sleep 9597952 dbuser 192.168.10.4 appdb 1 Sleep 9599442 dbuser 192.168.10.9 appdb 1 Sleep More Features: If you would like to pimp out the output of mytop a bit you can have the display in colors rather than the boring black and white default. This is also quite useful if you plan to watch a mytop session. To do this you need to install the Perl module Term::ANSIColor. You can do this using the CPAN interface. Your distribution might have a readymade binary for it, which you could install using apt-get or YUM. Use the "-color" or "-nocolor" options to enable or disable the color display. A file called ~/.mytop will be created in your user's home directory which will contain the settings for mytop. You can configure options that you want mytop to use by default. For example, if you want a color output by default make an entry in the file with "color=1". If you want to use a different port from MySQL other than the default 3306, add the line "port=3307" with the correct port number. You can setup things like your hostname (host=localhost), username and password also. This way, you don't have to write out these things in your command. Another useful setting is the "delay=5". You can change this to a higher value if you are running a load test for a long period of time and don't want too much data. The default value is five seconds. You can also set this on the fly using the -s setting when you execute the mytop command.

Motorola Xoom Android 3.0 Tablet Computer: The iPad 2 Killer? Posted: 21 Feb 2011 09:25 PM PST After the slick Motorola Xoom tablet computer has been considered as the best device at the Consumer Electronics Show (CES) in Las Vegas, it seems like the hype has never ceased. Being the first gadget to run the very latest Android version from Google - Android 3.0 Honeycomb, it is regarded by many as a potential threat to Apple's domination on the tablet computer market. A month after the CES, at Mobile World Congress, the Xoom has impressed many critics once again. But does it have what it takes to compete and beat the soon-to-be-released iPad 2? The Motorola Xoom features a 10.1-inch. touch screen (1280×800 resolution), capable of playing high-definition content. It utilizes the innovative and unbreakable Gorilla Glass display. The Xoom is powered by a dual core NVIDIA Tegra 2 (1 GHZ) processor, and it is equipped with 1GB of RAM and 32 GB of internal storage. It has a built-in 5-megapixel camera with LED flash on the rear that can record 720p videos. Whilst in the front, there is a 2 MP camera made for making video calls. The Motorola Xoom has an HDMI port, which means you can hook it up to a much a larger monitor or HDTV to fully enjoy any high definition video. The Motorola Xoom has an awesome candy bar look that seems to lure you into its wonderful technology. Some other interesting features of this tablet computer: Accelerometer, Gyroscope, Compass, and Barometer. Main features and technical specifications of the Motorola Xoom: During the 2011 Super Bowl, Motorola showcased a commercial (see the embedded video below) that was intended as a satire of Apple's landmark 1984 Super Bowl ad. The advertisement also highlights the slick Android 3.0 interface and some of its cool built-in apps. I know that it is not fair to compare Motorola Xoom to the first generation iPad. But what if we will match the Xoom with the upcoming iPad 2. Which one will you choose? In terms of processing power, it seems like the iPad 2 will be as fast and powerful as the Xoom. There are valid rumors that the iPad2 will also have a dual-core processor and 1GB of RAM, which is a huge leap from the original 256 MB one. When we talk about other hardware features particularly the camera and the display, I think Motorola Xoom will have a little edge over the iPad 2. Apple will likely put a less powerful camera on the iPad 2 and may still use the same display technology with the same screen resolution found on the first iPad. I believe no mobile OS could beat Android 3.0 Honeycomb at the moment. But since we haven't seen the next version of iOS (to be released around Q2) yet, I will just keep my mouth shut and won't make any comparison in the scope of operating system being used. It would be hard not to be impressed with the Motorola Xoom and Android 3.0 combo. In terms of overall features and capabilities, they are ahead of the pack as of the moment. So will the Motorola Xoom beat the iPad 2? I'm going to leave that question for you to answer.
