Awesome Raspberry Pi Supercomputer Build

This is in my opinion the coolest project I have ever come across for the Raspberry Pi. You have to check this out if you are true geek. Also they include some of the best most detailed instructions on how to repeat this project. This is a must see and there is a video too.

Introduction to Synaptic Package Manager

In this short video we will go over the Synaptic Package Manager and at the end you should have enough information to be able to use and explore this terrific tool.

I hope you enjoyed the video and will continue to explore. Synaptic is quite powerful and capable of so much more than I have covered here.

How To Use Software Manager

This is a short ‘How To’ video I created on how to use the Software Manager in Linux Mint 14 XFCE. This is a basic instructional video and is mainly aimed at the newer Linux users. We welcome comments and suggestions from the more experienced users too. This was created using the Record My Desktop utility and after the upload to You Tube has lost a bit of its clarity unless you run it in 720p. In the native ogv format it was very sharp. I hope you enjoy it. Click the link to view the video.

What App Do I Use?

Now that you have Linux installed you may be wondering what do I use to replace (insert any Windows or Mac application name here)? This is a very common question even with the distributions that come with an application for almost every need and purpose. What makes this so tough to answer? In my opinion it is mostly we simply do not know what is available and what the new applications do that are already installed. Linux distributions can and do provide hundreds to thousands of applications for many uses. So many in the mainstream distributions that it can be mind-boggling.

Even the lesser known Linux distributions such as AntiX can pull applications from the repositories of the much more widespread distribution Debian. And that adds another question for some people, what is a repository? (Answer: A collection of software maintained, tested and updated for a particular version or distribution chain.) This can all be very confusing to newer users of Linux. (Note also that I used the Debian tree of Linux as an example but could have picked several others, Slackware, Red Hat, Fedora all have distros based on them that pull from upstream repositories and also maintain their own repositories supporting themselves and this listing is certainly not all-inclusive at all.) Some distributions use packages they either create or bundle all while maintaining the main distribution giving their users many choices for applications of all types.

I think that most users will figure out the replacements for Office software like Writer and Calc. We will get used to seeing Rhythmbox instead of Media Player. Nemo, Nautilus or Thunar will become very familiar for interfacing with the file system. But what many do not know is there are alternatives and sometimes several to do the same thing. For example, music players is a category most of us will use. I named Rhythmbox above but could have named Banshee, Clementine, VLC, Kaffeine, MPlayer or Totem and this list is not totally inclusive and even crosses boundaries for other media types many of them can handle just as Windows Media Player handles multiple media types. This is just one category and one example, there are many applications that have alternatives.

Knowing what we want to do is the first step, finding the application is step two. This can be as easy as learning the name of an application that is already installed but we did not know the name of or learning how to pull from the repositories one of the thousands of applications that are there waiting to be used.

Nearly all of the distributions are making finding what you want easier than ever and installation of the software is extremely easy too. But what do you do if you have this favourite Mac or Windows program and want a Linux alternative but do not know the name of one? Well you can search the Internet, that may or may not tell you the name of the package to install. And you are definitely much better off installing from the repositories for your distribution even if you do find it on the Internet. This ensures better security and the meeting of all dependencies for the application.

Or you can use a tool like this one, the Linux App Finder. This is a really cool website where you enter the name of the program you want to replace and it turns out choices for alternatives. Many if not all of them will be in your repositories or a repository you can add as an additional source. You can even install some of the programs from the site but the repositories for your distribution are the preferred method.

Here is a screen capture for a search of notepad replacements as an example.

Search for notepad alternatives.

This is a decent list to get someone started and I doubt it is all of the available replacements for notepad. I stumbled onto this website a few years ago and found it to be very helpful. I hope you find it helpful too.

How To Install Atheros Wired Drivers

Wired driver installs? Yes if you are using the newest of chip sets from Atheros, it might not be in the kernel yet and you could be facing no interface found when attempting to configure the network. The driver patch is pretty easy to install if a few steps are followed while using wireless or from another computer.

Before you start run the command lspci in a terminal window to determine what driver you need. You will see something similar to this at the bottom of the output window:

02:00.0 Network controller: Broadcom Corporation BCM4313 802.11b/g/n Wireless LAN Controller (rev 01)
03:00.0 Ethernet controller: Atheros Communications Inc. AR8162 Fast Ethernet (rev 10)

In my case I have the Broadcom BCM4313 wireless controller and the Atheros AR8162 Ethernet controller installed as hardware. I am using kernel 3.5.0-21-generic #32-Ubuntu SMP Tue Dec 11 18:51:59 UTC 2012 x86_64 x86_64 x86_64 GNU/Linux in this Linux Mint 14 XFCE edition. In my case the wireless was indeed supported right away but the wired controller was not.

I first found the instructions here on the Linux Foundation but for me they were missing the crucial step of installing Linux headers build-essentials which is explained in this Ubuntu forum post here. The wget command in the instructions will pull drivers from this index. On the Linux Foundation site you will see a list of two chip sets, alx and atl1c. These instructions are for the alx series of chips. If you have the atl1c chip it might be as easy as replacing the alx in the command with atl1c but I have no way in which to test. These are the instructions I followed in a terminal window for the alx controller:

sudo apt-get install linux-headers-generic build-essential
wget http://www.orbit-lab.org/kernel/compat-wireless-3-stable/v3.6/compat-wireless-3.6.8-1-snpc.tar.bz2
tar -xf compat-wireless-3.6.8-1-snpc.tar.bz2
cd compat-wireless-3.6.8-1-snpc
./scripts/driver-select alx
make
sudo make install
sudo modprobe alx

Note the line starting with wget is wrapped to the next line. If all went well you now have a wired connection active. For some they will already have the build-essential files installed and can skip this step but for me this was the one line missing in other instructions that made this work. It does not hurt to run it again since if they are installed the command will tell you. Also note that if this is being done on another computer, follow the instructions to get the driver patch and transport it to the computer needing it. Once copied to the target computer start again at the tar command. Since this is a kernel patch, if you update the kernel you will need to run this again until the patch becomes part of the kernel.

I hope having this all in one place will help someone get connected until this patch makes it into the kernel itself.

Linux Mint 14 Nadia Is Out In KDE

Hot on the heels of the XFCE release, the Mint team has released their KDE version. Now I have to admit I am not a big fan of KDE. But there are certainly plenty of fans out there and this edition will be sure to please. Sporting the KDE version 4.9 there are plenty of new and improved features to go along with the Mint customizations.

Since I am not too familiar with KDE I will keep this post short. I want to invite the comments of those who do use it whether it is with Mint or another distribution. I have always stayed away from KDE because I have been using more under powered computers and did not like the performance I was getting. This goes back to version 3.5 with Mepis for my experiences. I am sure things are greatly improved and I often read much praise given to KDE on various versions. But for me I am spinning the XFCE edition and will post on this soon. So give it a try and let us know how it performs for you.

Linux Mint 14 Nadia Released In XFCE Edition

Hey all you Mint and XFCE fans. This is what you have waited for the Nadia edition of Mint 14. I looked at the RC release and I thought it was a finished product so this must be really good. I am starting my download now. If you can spare a few bits consider using and sharing the torrent for a few days. This is a super simple way to give back in a small but meaningful way. Servers get hit pretty hard during a new release announcement.

I have been using the Cinnamon release of Nadia for a week or more and I really have enjoyed the performance, the new looks and some neat features. XFCE proves to add just as many new features as Cinnamon if not more. Look for better artwork, XFCE version 4.10 and more. If you run this version let us hear about it.
