Researching a project, I came across a P.C. Magazine article about building a new computer for under $200.00. They use a Linux operating system to keep costs down, and focus on cheap parts. With the cost of memory at an all time low, this really isn't a tough task. I've been looking into this and want to try it right after the first of the year.
If you're into cheap tech, and thought about seeing how cheap you can actually build a computer for these days. Click here to read the complete P.C. Magazine article.
My Linux skills have been limited to a basic install, and getting around in the system. I've recently decided to take the O.S. more seriously and become a full time user and more of a Linux hobbyist. This is a place for me to post notes, and other helpful information. The information here is centered around Fedora and KDE but I do post about other GNU/Linux distributions. You can find useful notes, book reviews, tutorials, videos, and whatever else I think will be useful for learning this O.S.

Remove Part of a Software Package Without Removing All Dependencies.
If you install a program using yum and you don't like some of the dependencies, and you know the program will run without them. You can use this command to remove them.
rpm --nodeps -e packagename
The command basically tells rpm not to check for dependencies --nodeps and the -e is for erase. Replace packagename with whatever your removing.
If you try and use yum to just remove the dependency, in most cases it will try to remove the entire package. Using rpm allows you to just remove the one or two dependencies you don't want and leaves the rest of the install intact.
Bloggers note: update 10/19/13, using this will give you a warning the next time you use yum.
Warning: RPMDB altered outside of yum.
Basically the warning is simply letting you know that the RPM database has been altered due to the dependency you removed with rpm and not using yum.
If you get this warning just use yum clean all
rpm --nodeps -e packagename

Yum local install localinstall
So you downloaded an rpm and need to install it locally. Download the file. Move the file to wherever you want to place your rpm files. I simply named mine rpms. In terminal, cd to your rpm directory.
cd rpms
yum localinstall whatever_the_file_name_fc18.x86_64.rpm
This comes in handy when you don't want to install an entire repository that you probably only need one file from. The downside is you want to make sure you already have all the dependencies, otherwise you need to download them and install them as well.
cd rpms
yum localinstall whatever_the_file_name_fc18.x86_64.rpm

Update, what's up ! Information overload.
It's been a minute since I've posted here. Things have been pretty hectic and I've been suffering from a case of information overload. A couple people I know needed web design, so I decided to start a small web design company. I registered a domain, got my dba, and started New Aeon Design. If you're into graphic design and web design, I created a blog about design, just click on the blog link. If you stop by the website, it's a bit sparse. It's like the old saying about the mechanic, "he usually has the worst car" I've just been designing and haven't had the chance to blog, or work on my own site. This all came about right after I had my first Linux disaster. Actually it was probably more of a KDE disaster because the kernel seemed to be loading fine, and shell was working no problem. KDE just wouldn't load.
O.K. , so better late than never. I have no clue what happened with my first Linux disaster. It was a blessing in disguise, but like all computer crashes it was a pain in the ass and probably couldn't of come about at a worse time.
I clicked a link on the internet, when I went to the site my browser started acting weird. I opened and closed Firefox, nothing changed, rebooted the computer and KDE wouldn't load, went directly to shell, with a weird error message that I probably should of wrote down for blogging purposes. I probably could of repaired the installation, but was thinking about getting rid of Windows 7 and the whole dual boot computer anyway. So I opted to format the drive and upgrade from Fedora 17 to Fedora 18 and wipe Windows from the drive. I can only guess that I had something in Firefox settings not very secure, and the browser loaded something it shouldn't of.
Between external hard drives, cloud drives, and keyring usb drives, I had 99 % of my data backed up. I lost a template or two that I just started working on but nothing major. I spent the next couple weeks organizing my new drive, and going through about 12 gigs of photography, that sucked something fierce. I then got a couple more web design jobs, which leads me to here.
Meanwhile, back at "Notes On Using Linux" and blogging in general. I've decided to try and come up with some type of blogging schedule. This has to be done, I currently have multiple Tumblr blogs which are easy enough to update every day, this blog, a new blog about design that can be found here, and my-amateur-photo which is also suffering from not having time to post too.
So to sum this long winded update up, I'm going to try and post here at least once or twice a week. I'll probably be posting a lot about open source graphic design, and web design software for a bit. As of late, that's what I've been using mostly. The Fedora 18 install is working out great, and I'm really happy to be a full time Fedora user now. On that note, thanks to all who are following on Google Plus, I'll be posting more news, and info over the week and thanks for following.

Software Review KColorChooser
After recovering from my first Linux disaster, I promise I'll post more on that in the next couple days. I wiped Windows from my system and did a minimal install of Fedora 18 KDE. So long Windows ! After the install, I played around a bit to see exactly what was pre-installed in my computer, removed the packages I had no use for, and found a couple interesting surprises. My favorite one is KColorChooser.
One of the things I love about Linux is all the great software available for graphic design, and web design. KColorChooser is another great example of some of the great software available for designers. This is a really simple program that allows you to select colors from either the color pallete, or anywhere on the screen. Now that I've been doing a lot of web design I've wanted to look for a program just like this. This is the perfect program to use when you're developing your color schemes on web pages, and graphics.
When you load the program a small color pallete opens and you can just mouse click on the color selection. KColorChooser then shows you the rgb values along with the html hex values. Now, one of the really cool features of this program is you're not limited to the color pallete. Let's say you download a really cool wallpaper and love a particular shade of blue found in the image. KColorChooser will allow you to select the color from anywhere on the screen. So, just click the color dropper icon your cursor will transform into crosshairs and click on the part of screen with the color you want and KColorChooser will give you all the color values you need. The same thing if you're surfing the web and come across a cool color scheme on a website, or web graphic. Open KColorChooser , click the color dropper, click on the part of the website that has the color you want, and voila, KColorChooser gives you all the info you need to use that color in your next design project. The program loads quick, uses minimal system resources and really couldn't be any more convenient !
Finding this in the graphics section of my application launcher really was a pleasant surprise. I've wanted one of these color choosers on my computer for a while now, but just haven't gotten around to it out of sheer laziness. Thanks KDE !
One more KDE program worthy of mention, is KCharSelect. It's a simple character map that comes with most KDE installs. When you need a character map, just open your terminal, type kcharselect, and the image map will load on your screen. Very simple to use, and comes in handy when working with different fonts, dingbats, and webdings.
Even if your not using a KDE desktop, these programs are available for most Linux distros. If you don't have these programs do a quick search of your repositories and see if they're available for install. Both programs save you time, are easy to use, and use very limited system resources. I give both these programs five penguins and a thumbs up !

Fontconfig warning: "/etc/fonts/conf.d/50-user.conf", line 9: reading configurations from ~/.fonts.conf is deprecated.
Installed some fonts the other night in the new Fedora 18 KDE, and today when I went to load kcharselect from terminal I got this message.
Fontconfig warning: "/etc/fonts/conf.d/50-user.conf", line 9: reading configurations from ~/.fonts.conf is deprecated.
I did a bit of Googling and it seems to be a common problem across many distros. I found this in an Ubuntu forum and it seemed to take the problem away.
mkdir .config/fontconfig
mv .fonts.conf .config/fontconfig/fonts.conf
When I ran the mkdir command, it said I already had the proper directory, so I ran the second command and everything seems to work fine since. I downloaded my favorite set of dingbats and they installed fine. Made this real quick to test them out.
Punk dingbats font downloaded at.
