I just recently took on a project at a major Chicago newspaper, and they are moving from Solaris to Linux. One of the pieces of this project will involve converting some of their Oracle applications over to EnterpriseDB (Postgresql+). From what I was led to believe, EnterpriseDB is a drop-in replacement for Oracle, and most applications can be run without any modification. Does anyone out there have experience with this? What type of issues should we expect?

Debian GNU/Linux 5.0 Lenny Released March 10, 2009

Debian GNU/Linux namely releases version 5.0 aka Lenny. The last release (version 4.0 code named Debian Etch) was release almost 2 years ago!

Debian is infamous for its long release dates. It took almost 3 years for the jump for Woody to Sarge to happen. Though Sarge to Etch happened in a mere 22 months. Having said that, Debian is widely respected for rolling out a robust and secure Linux distribution that supports more architectures that other distributions. And the latest official stable release “Lenny” is no different.

Although Debian is a rock solid Linux distribution, it doesn’t come bundled with the latest versions of softwares. So if you are looking bleeding-edge or even leading edge you it will be up to you to install and configure the latest and greatest, but you can feel confident that you have a solid operating system to start from.

Lenny is the first Debian distribution with a Live system that allows you to try Debian without installing it on your computer’s hard disk. You can get Debian on Live CD, USB Sticks, or boot if of the net.

Debian GNU/Linux version 5.0 (Lenny) can be downloaded at Debian.org.

Are you a PC or Mac? Does it even matter? February 14, 2009

In my area of expertise it doesn’t matter! We run Windows and Linux on MacBook Pros! Oh yeah.. are you a Sun, AIX, or HP/UX?

Sooner or later you will have the MacOS running on a PC if someone hasn’t done it already.

Windows versus Linux.. Again!?! January 20, 2009

linux-versu-win-1Ron Barrett of Network World is claiming that “Windows 7 will crush Linux” because he like other Microsoft junkies doesn’t understand why people (like myself) use Linux. People like Ron are good a stating the obvious stuff like:

Windows 7 installs easier, has simpler configuration of user settings, greater availability of software, blah, blah, blah

Take a look at this one sided article that subtly points out most of the problems Windows has to begin with. Aside from the server operating systems which tend to be lean on a vanilla install (and I am being generous), the more mature Windows gets, the more bloated it gets; The more features it packs, the more resources it needs, and don’t forget the hassle of day-to-day upgrades as well as service pack releases. Mainstream Linux distributions are not oblivious to updates, and have methods of distributing updates as well, but receiving updates in most cases doesn’t depend on purchasing the “Boxed” version of the product.

Windows is including POWERSHELL and that’s great, but Linux has had multiple power-shells since the beginning. So way to catch up there Windows, Microsoft finally understands that scripting is important to the real IT administrators.

Notice that features of the “New” Windows GUI (Macs are guilty too) were simply stolen. A lot of the eye-candy that was implemented in Windows Vista existed for some time in Sun Microsystems Looking Glass, KDE, and GNOME. Virtual Desktops like the Compiz and Beryl project (Logical or 3D) have been solid on Linux for some time now. But enough with the look and feel business. Windows, GNOME, KDE, and Mac desktops can be made as glamorous as you would like them to be, but hands-down you have more options and more control on Linux. You have dozens of window management choices at your disposal on Linux and other UNIX operating systems. I will give Windows and the MacOS credit for being very integrated and cohesive operating environments, but this isn’t hard to accomplish when there is only one entity is setting the rules. KDE, GNOME, and others are cohesive as well, but a lot of the components that are the building blocks for these window managers come from more that one open source project. But as time goes by they are getting tighter and tighter by the moment.

As far as applications go, well I cannot tell you how much money my company has saved businesses by using alternatives to mainstream computing solutions (like Microsoft, Oravle, SAP<, etc.) by using their open source counterparts. These savings are across the board server and desktop, as well as development platforms. Just do some research for yourself, and see what kind of savings you well get if you replace something like Windows server/SQL server with Linux/MySQL or Linux/Postgresql. You can IIS, or Apache, both are mainstream solutions, but one is free. For the most part the former and latter do exactly the same thing except one will cost you more than the other. If it is in issue of expertise or support you will have to find that expertise regardless of what it you’re using if it’s proprietary or otherwise. Some businesses are scared of projects based on open source technologies because they fearful of having support issues, but those of you who are should take a look at companies that use mostly open source softwares like Google, Amazon, and Yahoo which are using open source applications for mission critical services. I bet you they saved a ton of money going this way instead of using proprietary solutions.

On the desktop Linux is close but has a ways to go, but in my view this is to be expected because there isn’t one entity that governs how the desktop should look, feel, and function unlike Microsoft and Apple, but projects like KDE and GNOME are getting there slowly but surely. I also think that a stable full-featured Windows emulator integrated into the Linux desktop will give windows users a better incentive to a the very least test Linux as an alternative desktop. I myself will admit to using Windows, but I use it primarily for Microsoft Office (mostly Word, Powerpoint, and Access), but with Crossover Office from CodeWeavers I can run those and more on Linux with few issues.

On another note I like the fact that I can pack a fully-functional version of Linux on a 512M USB Flash drive and take that as well as my data with me wherever I go. Try doing that with Windows 7! Or maybe you can even try ReactOS (which is in alpha now).

GRUB Defined! January 8, 2009

The GRand Unified Bootloader (GRUB) is the mainstream choice for most Linux as well as other distributions. This very capable bootloader is taken for granted by most people who use it. Yes, this full featured package has been in the spotlight for sometime, but how much do powerusers actually know about it?

My experience for the most part is mainly using GRUB as a means to experiment on-the-fly with passing command line arguements to the Linux kernel as well as selecting an alternative to the default operating system. But, lately I have been searching for solutions that would make it easier to boot from certain types or media not configured inside of the GRUB menu.

I have been researching ways to boot a USB device directly from the GRUB interface similar to booting from say something like the first hard disk. But how do you do that when you don’t know what device the BIOS assigned the USB (or flash) disk? How do you actively seek information about disks that are currently recognized at boot time? Well, in my research I have been frustrated while googling many pages reading from blogs and forums that explain how to install GRUB on a USB stick which is relatively painless, then I came across one of the most comprehensive GRUB HOWTO’s I have seen to date. I have been playing with the examples since, and I find them extremely useful so I though I would share them with you.

This page goes through the every practical use of GRUB, and I found the examples a good resource for the Linux professional as well as the poweruser. If you use GRUB and you would like to get a little more intimate with it’s command feature set check out The Grub Page. You may want to bookmark this because it is an excellent resource.

Linux-based Unified-Communications, Microsoft Exchange alternative Free! December 21, 2008

New York based Unison Technologies debuts its Linux-based unified communications software. The client-server software package is targeted for businesses with 50-250 employees and includes Internet telephony, e-mail, instant messaging and shared contact and calendar features, which mimics some key features of Microsoft Exchange. Also has an Outlook-like client for Windows and Linux workstations.

It’s great that this runs on Linux (RedHat and Ubuntu) because that keeps the cost low. But if you want to use software for free, it will include advertisements. This sounds like something worth looking at, read more here. I am going to look into this and see what it’s all about.

Linux On Brazilian Voting Machines November 24, 2008

130 million Brazilian voters were turned into users of one of the largest Linux deployments worldwide: the 400,000 electoral sections in all of the 5,563 Brazilian municipalities were running electronic voting machines, and the Linux kernel was running on all of them. These voting machines have been used in Brazil since 1996, and are rugged, selfsufficient low-spec PCs. Technical details about this Linux deployment and implementation are available elsewhere (and more will come, for sure), but I thought it would be interesting to show some pictures and a movie – shown at the source link below – of Linux booting on these voting machines.

Will Linux suffer under Obama? November 18, 2008

This is one to look at.  Since President Elect Barack Obama promises change, and a result of this change will be more working Americans.  Is that going to have an adverse affect on the open source community?  Will they now have less time to develop software and the operating system pieces of Linux?

Change is here!

Well now that the ARM is mature and running in all types of portable devices, I am just waiting see the impact the Intel Atom will make on the cellular market.  I have been following this quite some time, and I can’t seem to find an advantage of using the atom on a mobile phone yet.  But Ubuntu Mobile will be running on an Atom processor, but only on Mobile Internet Devices (MIDs).  Check this out…
