scale.png
 
I’m quite pleased that my presentation proposal has been accepted to the SCALE9x conference, to be held February 25 – 27, 2011 in Los Angeles, CA.  I hope you’ll join me for…
 
Category: Developers Track, Technology
Audience: Advanced, Intermediate, Beginner, Everyone
Abstract:

Unleash the power of your command line environment through this innovative, intuitive take on GNU Screen!

UNIX and Linux system administrators have been blessed with the GNU Screen utility for almost 25 years. Expert Screen users will swear by its importance in their toolbox. But the learning curve for new users getting started can be quite steep.

Enter ‘Byobu’, an innovative, intuitive approach to GNU Screen, brought to you by the Ubuntu Server community. Byobu is a set of wrapper scripts and configuration settings that unleash the power of GNU Screen for beginner and novice system administrators, while continuing to support Screen’s advanced features for expert users.

Byobu includes convenient keybindings, useful status scripts, sensible configuration defaults, and a curses-based utility for modifying some of Screen’s most important (but most buried) features.

In this presentation, the author of Byobu will introduce the basic flow of operation, and move into the advanced features of Byobu and GNU Screen. Any Linux user attending this presentation will be more productive when interfacing with their command line hereafter…

Get Slack!

I think Arch Linux, Slackware and maybe in a slightly different level Gentoo, are some kind of advanced Linux distribution, or better said for intermediate to advanced Linux user. I like to say that those distributions are for Linux lovers, people who is not afraid of the command line. I’m that kind of person, I like to be in control of my Operating System, and one thing I really like about Slackware and Arch Linux is that you need to enable the daemons, this way no matter how many of them you install in your computer it is still running light weight. Of course if you use Fedora or Ubuntu you can disable the daemons, but I prefer to be the one that enable them, and not the other way.

Various Problems With Reiser Fs File System Cause Data Loss in Linux

When the Reiser FS kernel detects an error on the hard drive, it prints some error messages on the screen. It might be a bug. In the Super Block of Reiser FS file system, there is an Error pasture. It is set when file system kernel notices something bad.

So, what happens in this case? May be the Linux user could not read Syslog and could not see the error message or the error is simple an overture of memory corruption, which could lead system to crash.

In such situations, when you reboot the system, this goes in the merry way, mounting Reiser FS file system with known errors on the same, using badly allocated memory locations, B-trees and directories etc. Double allocation of memory blocks and overwriting of blocks may also take place, making the files corrupt.

The final result of this whole problem would be the severe file system corruption. At this point of time, it becomes completely impossible to fix the file system errors for the user. No disk repair utility can detect the errors.

In even the worse scenario, the Reiser FS read Super Block code overwrites the Super Block at mount time. It makes the situations worse and the file system totally useless. After crash, you might come across the following error messages:

“S->u.reiserfs_sb.s_mount_state = SB_REISERFS_STATE(s);

s->u.reiserfs_sb.s_mount_state = REISERFS_VALID_FS”

In these grave situations, if you continue using system, the problems may become more terrible. The ultimate results of this whole mishap would be the loss of your critical business as well as personal data stored on your Linux hard drive.

At this point of time, the only thing which can save you from going out of business is data recovery Linux. It is the way out to retrieve all of your lost, missing and inaccessible data from logically failed Linux hard drive.

Data recovery Linux can be easily effectively and completely performed with the help of Linux data recovery software. Linux recovery software are easy to use tools, which systematically scan your affected Linux hard drive and extract as much data as possible.

Ubuntu Linux is Prime Time for your Business Desktop and Notebook Computing Environment

As a business consultant, web designer and photographer my technical know-how around doing system administration on my Microsoft desktop is limited and sometimes I do require the assistant of my computer engineering son to get it right. In a Microsoft Environment, keeping updated with respect to potential security breaches and patches is a constant vigil. The rigor of keeping current with OS updates, Norton updates and Spyware updates is time consuming. Valuable business hours each week are spend and lost on this task of self-administration dictated by the Microsoft Operating Environment.

So with the purchase of an IBM T40 (a tough notebook), increasing system administration time was not an option. This alone forced an serious consideration of Linux as an alternative operating environment. That was five years ago. Now an established Linux user, I can clearly profess the capabilities and benefits of Linux for small and large businesses, especially, when it comes to notebook deployment.

What Linux variant is best for small business and notebook deployment in your company?

As a small and medium business development manager with Sun Microsystems, exposure to Linux and the debate around its viability was a daily event. Questioning and challenging the virtues of Open Source (FREE) Linux versus Licensed Linux versions like Red Hat and Novell SuSE continues to this day . After years of personal use of Open Source (Free) Linux, I can never go back to running the Microsoft Operating Environment on my notebook. And once you can get Linux versions of Quick books, Quick Tax and Picasa (now available on Linux), there is no reason to stay in that perpetual administrative nightmare world of Microsoft.

Having successfully deployed two Open Source Linux variants on my IBM T40 notebook over the last 5 years, a compelling comparison can be made between Fedora and Ubuntu. Fedora, the Open Source version of Red Hat, required the installation expertise of some Linux gurus from Belleville Ontario. It worked fine, but required some Linux ninja system administration every 6-9 months. Administration items applied during these visits included upgrades to Open Office (the open source version of Star Office), Linux OS fixes and new peripheral drivers. This, again, turned out to be a drain on my scarce time for doing real business.

Now the Linux called Ubuntu is installed on my notebook. Ubuntu by Canonical is a full Open Source Linux based on Debian Linux. Ubuntu is now available on Dell systems and Federal Governments are adding this Linux operating environment to their list of standard available OS’s for all desktop and notebook computers.

Right out of the gate, Ubuntu was simple to install. You could even bring down a trial copy to experience exactly how it would behave on your notebook before downloading and committing the Ubuntu OS environment to your machine. But the best part is that Ubuntu continuously keeps on top of OS and all related application software updates. Ubuntu has an Update Manager that magically appears in desktop tool bar. And with a simple click (and password) you are kept current on the latest versions of Ubuntu patches, any Linux application software you have installed from Canonical and Open Office upgrades.

With Linux rebooting your machine after an update is nearly non-existent.

Oh, as an added treat with Ubuntu, Ubuntu boots up on your machine in less than a minute. I still go get a coffee when my Microsoft desktop is booting up. An additional benefit of Ubuntu: there is no requirement for installing ant-virus and anti-spyware software. Ubuntu inherently repels these vial scourges of the internet.

With Ubuntu your system administration life will become simple and painless. You can spend more quality business hours selling and marketing.

Want to cut hidden costs in your organization that manifest themselves as Microsoft self-administration by your end users?

Ubuntu is a must for you or your IT folks to consider. Seriously consider, test and deploy.

Budget-friendly With Tons of Flexibility, Linux Web Hosting Comes to the Rescue

Microsoft Windows is the most popular operating system (OS); thus, most web hosting companies cater to sites running on Windows, as expected. However, there is an increasing demand for hosts that can support websites running on other platforms such as Mac OS and Linux, just to name a few. For this article, we will focus on Linux web hosting.

Why do some people choose Linux web hosting? To start with, Linux is an open source OS designed after Unix. It means Linux is free, which is a fact that is easily a factor in some people’s choice of operating system. Aside from being free, Linux is also known to be very stable even in the midst of some heavy-duty multitasking. It’s also known to be flexible, powerful, and portable. The graphical user interface (GUI) looks great, too.

Whatever the reason may be, there’s no denying that more and more people are turning to Linux web hosting. If you’re comfortable with using Linux with Perl programming language, now is the right time to go for Linux web hosting. It has its place in mainstream, so any worries you may have about lack of suitable choices for Linux web hosting should be thrown out the window. There are a lot of affordable packages being marketed by web hosting companies for the Linux user.

Surprisingly, even if Windows is the most popular OS, Linux web hosting has more presence on the internet than Windows web hosting. The reason behind this is Linux’s open source nature. A lot of technological developments in web hosting are also open source. It’s easier for developers and programmers to experiment with different innovations when high fees and licenses are not part of the equation. Thus, Linux web hosting provides you with a lot of flexibility at almost no cost. When technologies update, you can go along with them without worrying about your budget because they are free.

Linux web hosting is also highly standardized because Linux, as an OS, is a standard platform. Thus, you can easily add to your website without too much hassle since everything is streamlined. You’ll appreciate this more as your website steadily and quickly grows. Long-term management with diligent maintenance is one of the most difficult things you need to do as a webmaster; luckily Linux web hosting can help in that aspect.

Take note, though, that there’s a downside to all the good stuff, and it’s up to you if it’s worth looking over when you finally choose Linux web hosting. Since Windows still dominates as the number one OS, Linux web hosting does not have a lot of technical support available for applications and languages that are based on Windows. Sure, you have a wide range of Linux-based applications and languages to choose from, but there are very useful ones that are Windows-based. You either don’t use them at all, or prepare yourself to encounter difficulties when you do.

Weigh your needs and wants before choosing Linux web hosting over Windows web hosting. Both have positive and negative aspects to them, and choosing what works better for your website is something only you can decide.
