Linux Anti Virus for Websites
Jan 30th
Just because you run linux does not mean you completely forgo anti virus. Your website can be broadcasting Windows viruses or malware. Clamav, run from the command line, will scan your web directories recursively to identify various concerns. Install Clamav:
Then you can run Clam manually or you can install a cron job for it to be run automatically. Running Clam as root allows you to scan the higher level directories. The following command will scan the entire computer and remove viruses and malware:
sudo clamscan -r / --remove
Set this as a cronjob to run in the middle of the night; add it to the root crontab list:
0 2 * * * clamscan -r / --remove

2014 – Windows XP Deadline
Dec 30th
Its time for a shift. Windows XP, the longtime staple of industries around the world, has a deadline. It will no longer be supported by Microsoft in 2014. Because of this companies will either need to upgrade to Windows 7, or some sort of alternative. Windows 7 costs been 4-6 thousand dollars for a 30 license pack. If your company has thousands of computer this is a whole lot of money. Why not switch to Linux, it is free. Is free bad? Is free not good? There are many people that do not like free, which is just strange. Not liking Ubuntu is like someone coming up to you and saying “here take this for free”, and you saying “no thanks I don’t want it”. What a strange notion that Linux is not liked by millions.
Ubuntu can replace the standard workstation. There are some thinks holding back the switch. The main thing is applications that require .net framework. Its really messed up that there is no support for .net framework in Linux. Using Wine .net framework can easily be installed, especially with Wine tricks, but using programs that depend on its functionality is another story. Various frontends to database applications use .net to access the server. Is there an alternative application, made by the company, that does not depend on .net? If your company has thousands of computers, and you can save over a million dollars just in Windows 7 license fees, is it not worth investigating? You’d be surprised there are many companies out there that would rather spend the million dollars than investigate if implementing an alternative is possible.
Ubuntu Karmic – Mac Mini – MythTV
Dec 15th
I gave up on OSX. I could not get the media center working the way I wanted. Plex and XBMC have their bugs, as previously posted, twice, preventing predictable functionality. MythTV for OSX simply is not as refined as its native Linux counterpart. It feels like running Windows applications via wine. I just scrapped OSX for Ubuntu Karmic. Out of the box, off of the cd, things work great. Audio works perfect. What didn’t work? The Mac Mini remote control. I tried for a day to get it to work the hard way. I saw that /dev/usb/hiddev1 was working and displaying data; shown with cat. But lirc would not bind to the device. Ultimately I removed the program, and ran a system update. Problem resolved; clearly a bug report was filed and a resolution provided.
Fanart and coverart work fine. The Linux based fronted is seamless compatible with the Linux based MythTV server. I didn’t even need to input the servers ip information manually. I did have to set the repeat feature, for each key in ~/.lirc/mythtv.
Now all I want is to have MythTV sleep the system and wake the system. I get it to sleep the system by making the halt script sudo pm-suspend. Adjust your /etc/sudoers files to allow passwordless sudo for /usr/sbin/pm-suspend. The halt script is configured in setup-general settings. Waking the computer is another thing that I have yet to get working.
LPI 101 – Linux Certifications
Dec 12th

If you go on Monster.com or something comparable you may see jobs that are requesting you to have various certifications. Most certification requests are for Microsoft, but there are various server jobs that require substantial Linux expertise. If you are going to be managing a Unix server knowing how to use Linux will help alot. You can grab a free Linux distribution that will give you access to basically the same environment as Unix. IBM has AIX which is a Unix derivative; but your not going to get your hands on AIX from a free download on the Internet. The same goes for Open SCO.
Learning Linux is the next best thing. To show employers that you have Linux experience you want certifications from the Linux Professional Institute. LPI provides a standardized test that is representative of an excellent understanding of Linux environments, and an ability to manage them.
5 Ways to Save Businesses Big Bucks, Enhance Security and Evolve
Oct 28th

Electricity is one of the biggest expenditures in the business world. Surpassed only by procurement, and human resources; reducing the amount of power consumed by electrical appliances can save a company millions. The first thing to do is configure your computers as thin clients. A computer can consume 30 or more watts each. If a Corporation has thousands of computers, and a thin client uses 50-75% less energy, then that translates directly to a 50-75% reduction in the utility bill. There might be a setup cost associated with 10,000 new thin client terminal, but that will be made back within the first year of use.
1) To implement a thin client setup the Corporation can use a Microsoft Windows product, which would cost money and be counter productive. The economical choice is to use Linux, and an out of the box setup can be achieved using Ubuntu. Talk about killing two birds with one stone; using Linux will eliminate the costly expenditure of anti virus subscriptions that all corporations have.

2) By implementing Linux the cost of maintenance will be dramatically reduced. You can have Linux machine running for years without serious security problems, and the entire update process can be completely automated and centralized to the thin client server. A corporation can significantly cut their maintenance costs with a thin client setup.
Most database applications nowadays are browser based therefore Linux is perfectly compatible with most existing systems. Firefox works on all Linux systems.
3) After switching to a Linux thin client server, all those pesky Windows license keys can be resold to needy customers. Theoretically the corporation can recoup several thousands of dollars, if not 10′s.

4) Then the old energy inefficient hardware can be resold, or donated to a organization of good will. Either an economical or philanthropic plus.
5) Then security can be enhanced by enforcing an outbound firewall to block all but the needed ports. Theoretically only several ports, clearly port 80, port 25, and several others need to be open. This will dramatically reduce the risks even if a computer becomes infected with a virus. Bye bye Norton, or Symantec. Save that 10-50k per year subscription fee.
Overall there are many reason to convert to Linux and some of the reasons are priceless. You really cannot put a cost savings on potential security risks, which is one of the biggest selling points of Linux. Ubuntu is free, how can that be beaten?
So all you tech savvy, under appreciated employees out there start dreaming up ways to approach the right people in your company with a way to save them million. If thousands of you draft presentations and attempt to talk to higher ups, at least one of you will hit a jackpot. Why not let that one person be you.
