These tips will help you minimize power consumption, heat, waste and chaos.

How green is your data center? If you don’t care now, you will soon. Most data center managers haven’t noticed the steady increase in electricity costs, since in most cases they don’t see those bills. But they do see the symptoms of surging power demands.

High-density servers are creating hot spots in data centers that have surpassed 30 kilowatts per rack for some high-end systems. As a result, some data center managers are finding that they can’t get enough power distributed out to those racks on the floor. Others are finding that they’ve maxed out the power utility’s ability to deliver additional capacity to their location

Fortunately, there are many steps that data center managers can take to start reducing power consumption in existing data centers without making a huge investment — or sacrificing performance or availability.

1. Consolidate, consolidate, consolidate.
2. Turn on power management.
3. Upgrade to energy-efficient servers.
4. Use high-efficiency power supplies.
5. Break down internal barriers.
6. Follow the standards.
7. Advocate for change.

If you’ve ever typed a command at the Linux shell prompt, you’ve probably already used bash — after all, it’s the default command shell on most modern GNU/Linux distributions.

The bash shell is the primary interface to the Linux operating system — it accepts, interprets and executes your commands, and provides you with the building blocks for shell scripting and automated task execution.

Bash’s unassuming exterior hides some very powerful tools and shortcuts. If you’re a heavy user of the command line, these can save you a fair bit of typing. This document outlines 10 of the most useful tools:

1. Easily recall previous commands
Bash keeps track of the commands you execute in a history buffer, and allows you to recall previous commands by cycling through them with the Up and Down cursor keys. For even faster recall, “speed search” previously-executed commands by typing the first few letters of the command followed by the key combination Ctrl-R; bash will then scan the command history for matching commands and display them on the console. Type Ctrl-R repeatedly to cycle through the entire list of matching commands.

2. Use command aliases
If you always run a command with the same set of options, you can have bash create an alias for it. This alias will incorporate the required options, so that you don’t need to remember them or manually type them every time. For example, if you always run ls with the -l option to obtain a detailed directory listing, you can use this command:

bash> alias ls='ls -l'

To create an alias that automatically includes the -l option. Once this alias has been created, typing ls at the bash prompt will invoke the alias and produce the ls -l output.

You can obtain a list of available aliases by invoking alias without any arguments, and you can delete an alias with unalias.

3. Use filename auto-completion
Bash supports filename auto-completion at the command prompt. To use this feature, type the first few letters of the file name, followed by Tab. bash will scan the current directory, as well as all other directories in the search path, for matches to that name. If a single match is found, bash will automatically complete the filename for you. If multiple matches are found, you will be prompted to choose one.

The reference is an easy read and printer friendly.  So if you’re just starting out on that Unix admin job or just trying to get around your own Linux install, this guide is for you. Unfortunately as with the first article, I was not able to fit this one into the blog template so I’ve created a separate html file.  Please read Common Linux Network Commands here.

Finally, i have a time to update the latest version of Wordpress 2.2. After read some guide to upgrade, follow the step that suggested…after everything done, try running “http://techgeek.mynothing.net/wp-admin/upgrade.php”, then the result showed SUCCESS without ERROR. Job done.

Fedora is a Linux-based operating system that showcases the latest in free and open source software. Fedora is always free for anyone to use, modify, and distribute. It is built by people across the globe who work together as a community:

The big innovations touted for this release are:

• Revisor tool - a graphical appliation built on top of Fedora’s other build tools that gives flexibility to build an ISO, a live CD, etc. Mike Spevack, Fedora’s project leader, feels this is Fedora’s crown jewel. Customized versions of Fedora are now possible to an extent that was not available previously.

• Live CD - first time for Fedora, (however not an industry shake-up here).

• Kernel-based Virtual Machine (KVM) technology has been integrated with the Fedora graphical virtualization manager tool. KVM provides a full virtualization solution, and users have a choice between KVM and Xen, along with Qemu, in this release.
