I just started using the Press This feature of WordPress, and I quickly ran into a problem. Each time I’d try to use it, I’d get a 404 error page.
I’m not sure exactly what the issue is, but there is an easy fix that you can find here.
I recently watched the entirety of the Revolution OS documentary. While it definitely is not a video that can be enjoyed by most people, nor even most computer users, it is a very intersting watch for a number of reasons.
Visiting the documentary’s site, you quickly gain a sense of what this documentary is aimed to be: “… the inside story of the hackers who rebelled against the proprietary software model and Microsoft to create GNU/Linux and the Open Source movement.” However, that’s not what this video is about.
When I first started watching the documentary, I thought I would get this intimate insight into how people made calculated movements against the growing monopoly of Microsoft’s operating systems. In fact, this isn’t anything near what actually happened.

A few days ago, I blogged about changing the timezone on a Linux server. In the post, I mentioned how the zoneinfo files needed to be updated in 2007 due to congress expanding the number of days that Daylight Saving Time covers. However, I did not go in depth about how to update the zoneinfo files.
Since then, I’ve received many search queries from people looking for information about why their server did not properly update when the Daylight Saving Time change hit. For instance, I got queries of “is daylight savings default in centos”, “daylight savings time didn’t change centos”, “dst timezone change centos”, and many more. It’s clear that there are server administrators out there that are very confused about the Daylight Saving Time situation on their server.
Today, I hope to remedy that problem and give server administrators the information they need to update these zoneinfo files. I typically focus in on specific platforms, but today, I’ll try to cover as many distros as I can as well as provide a universal solution.
I’ve had a lot of fun recently posting about how to do stuff on the command line in Linux. My focus is specifically for Ubuntu users, but the information and techniques can be used for any Linux distro.
Since I’m probably going to end up with a lot of content under this topic, I’ve decided to create a dedicated tag: Mastering the Command Line. I’ve gone through my older posts on this topic and tagged them as well. So, make sure to check out Mastering the Command Line if you want to know how to become a command line power user.
Back to today’s topic. You’re starting to learn how to use the command line, but it’s annoying to always have to type in similar commands over and over. If only there were a way to pull up commands that you’ve already run to run again as is or to quickly modify. Today, I’m going to teach you how to do exactly this.
Have you ever seen a bunch of ^M characters in a text file? This odd character at the end of a line can also be represented as a Ctrl+M or <CTRL>M. You don’t know what it is, and you want it to go away.
Today, I’ll help you understand what that odd ^M character is, why it is in some of your documents, and how to get rid of them.

I’m more or less taking the night off. I’ll leave you some good reading material that should cover just about any reader that comes here.
- Make Linux: Harder – Better – Faster
This page is a great compilation of links on how to improve security, speed, functionality, or appearance of your Linux system. - Firefox Minefield
Very interesting version of Firefox that is in development. Apparently, it is capable of massive speed and gives Chrome a run for its money. - Conky
A highly-customizable graphical system monitor for your Linux desktop. - Armed and Dangerous
A blog I just happened upon today that has many great reads. The topics are varied, but there should be a little something for everyone. I was hooked with the My comment to the FCC on DRM post, as I share many of the feelings that the author does on the subject. - Swift Weasel
This project builds Firefox from source to provide optimized builds for the Linux platform. It’s still in the early stages but has potential.
I hope that my big post yesterday makes up for my weak one today. 
Did you know that you aren’t limited to working on one thing at a time while on a Linux command line? You can actually “minimize” a program that you are in, get back to the command line, and then return to the program whenever you’d like.
When you run a program or script on the Linux command line (from now on referred to as the shell), you are creating a new job. For those that are used to GUI environments, each of these jobs is somewhat like a window on the desktop. Just as you can have multiple windows and switch between them, the shell is capable of managing multiple jobs and allows you to switch between them.
There is a lot to cover, so let’s start simple by describing what states a shell job can be in.

I have a favor to ask of all my readers today. Cali Lewis of geekbrief.tv is in a contest to win “the Best Job in the World.”
This the title of this job is The Caretaker of the Islands of the Great Barrier Reef. The person selected to this position will travel the islands of the Great Barrier Reef for six months. During this time, they will make video blog entries talking about the activity on the islands.
I’ve had the opportunity to meet Cali before. She’s really a lot of fun and is a big supporter of Linux. Please give her your support each day by casting your vote.
In case you don’t know Cali, here is her video entry.
Without the Linux kernel, Ubuntu (and all the other Linux distros) would not exist. Despite this, most Linux users don’t know what a kernel is nor understand that the reason that Ubuntu is a Linux distro is because the kernel is Linux. All most users of any Linux distro is likely to know is that they will eventually have a large number of kernels installed on their system cluttering up their boot menu.
Describing what a kernel is and what it does is beyond the scope of this post. I do highly recommend that you first read the Wikipedia article on computer kernels followed by the article on the Linux kernel itself. I’d really like to do a post explaining what a kernel is in simple terms so that readers can gain a better appreciation for it and what it does for your distro. Please leave a comment letting me know if you are interested in this writeup.
Anyways, back to the topic at hand. What do we do with all these kernels that litter our boot menu? How do we remove them not just from our boot menu but from our file system as well?
Many of you fellow Ubuntu users will be familiar with the “Search for Files” tool that allows you to look for files. As is true with most things in Linux, there are great desktop tools, but more power can be found in Terminal than any streamlined desktop tool can match.
Today, I’d like to introduce you to a few tools that can turn a chore of finding files into an easy process.
