Linux Apps That Will Help You Graduate College

Filed under: General Linux,Linux Software — TheLinuxBlog.com at 8:12 am on Monday, August 1, 2011

This is the second guest post written by Whitney from Technected. Whitney majored in journalism and has been using Linux ever since. She now works for a large automotive corporation in the Midwest. In her spare time she enjoys playing video games, gardening and watching Dr. Who.

Linux is a very powerful OS, many people don’t know that. With all the mainstream programs that Microsoft creates, most people remain ignorant of the awesome programs out there for free that are being produced by Linux developers. Many of the apps out there can help you reach your traditional or online degree. Below is a list of 5 that will help you graduate college.

Task Juggler is a project management program. It allows you to keep all your tasks in order. All you have to do is enter in the assignment for class and when it is due as well as any other details that you may find pertinent to getting the project done. It’s especially helpful for online university students, who have less structured classes.

Every college course will have a syllabus and on the syllabus will be assignments that need to be accomplished. Task Juggler can organize this information and keep you on track with your assignments.

Star Office or Oracle Open Office is a regular word program that offers spreadsheet, presentation, drawing, database and formula programs. It is a mirror of Microsoft office but with an original drawing program.

What makes Star Office better than Microsoft Office is its ability to open multiple file types. It can open Microsoft office files as well as Corel WordPerfect files, TXT and HTM. This program may not have the same popularity of Microsoft, but it is free. When having to pay up to $150 on a college budget, Star Office really saves the day.

LyX is a document program that can make several different types of documents. With it, you can make word documents, math documents, science document and many others. This program specifically focuses on the structure of the documents and allows for any type of structure whether it is for a math assignment sheet or a block paragraph science paper.

Obviously you can utilize this program for any class and it beats having to go to the library and using a very specific program. Instead you can download LyX and get all your documents done in one program.

Free Mind is a program that helps you make notes. It is a digital version of the old spider web note taking that many students use for various subjects in school. The main idea rests in the center and then sub topics sprout off of that and then points link off of those.

Another nice point in Free Mind is its ability to fold these sub topics and point back into the main topic, giving Free Mind the ability to reduce clutter. The application allows students to flesh out their ideas for all the papers they will write for class.

Speed Crunch is a powerful desktop calculator that can calculate advanced equations. This isn’t your sissy desktop calculator. This calculator comes with a large screen where you can input long equations as well as define variables for the calculator to produce the correct answer.

For instance, y = x + 41. Enter x = 18 and the calculator does the rest. Speed Crunch has many other useful aspects including syntax highlighting and automatic completion, both will help in reducing errors.

These five Linux applications are great resources for college students or graduates. It’s unfortunate that many out there still don’t realize the abundant, free programs out there that can help them in their daily life, and even help them graduate and better their future.

Open Source Tuning with RomRaider

Filed under: General Linux,Linux Software — TheLinuxBlog.com at 6:30 am on Wednesday, June 22, 2011

RomRaider
This post features RomRaider, an open source software that is used for tuning. Not tuning or optimization in the traditional sense like optimizing shell scripts, but rather automotive tuning, specifically for Subaru’s.

It supports a lot of Subaru models and is able to tune supported ECU’s from various countries.

If you like living on the edge and can get over the risks it would totally be worth it. The consequences may not be for the faint hearted though:

  • An unreadable/unusable ECU.
  • A blown motor and its subsequent damage.
  • Unexpected behavior on the road or track that may cause injury or death to the user as well as others.
  • Violation of local and/or federal laws due to the modification of the factory ECU.

RomRaider is written in Java and is cross platform (Windows/Linux) Sorry Subaru driving Mac owners, you get no love. The interface, although clunky (I mean, it is Java after all) has some pretty cool graphs that display various information in a visually appealing format. If you own a Subaru and are interested in tuning, I’d give RomRaider serious consideration before other commercial solutions.

How to talk openly about open source software

Today we have a guest post written by Whitney from Technected. Whitney majored in journalism and has been using Linux ever since. She now works for a large automotive corporation in the Midwest. In her spare time she enjoys playing video games, gardening and watching Dr. Who.

You already know Linux is superior. There’s a reason you downloaded it, even if you had to overwrite your pre-programmed OS. You painstakingly created partitioned files for your /boot, /swap, root and /home files. You even bought a stuffed penguin — the Jesus fish of Linux users — to proudly display on your desk.

With great power comes great responsibility, though. Suddenly, everyone is asking you why Linux is so great, and if they should download it. Once you’ve worked with an OS for so long, it’s sometimes hard to simplify your answers for them, so here’s a handy list of answers for the masses

Ikea is a great place for affordable furniture that makes it an attractive resource for technology enthusiasts. IkeaHackers.net has a lot of interesting hacks that could be used by Linux users.

The kids shoebox dual computer cabinet looks like it runs Ubuntu. It also looks like kids would love it. I need to know where I can get a keyboard and mouse like that.

This may be old news but it is cool none the less. If you haven’t seen it I Introduce to you the LackRack mount your switches, or small 19″ rack mount equipment in a table. What another genius use for a piece of Ikea furniture! Here are the handy lack rack Ikea instructions in a handy pdf.

People who want to advance their knowledge sometimes look into an online PhD.

Mikogo Calling for Beta Testers

Filed under: General Linux — TheLinuxBlog.com at 9:32 pm on Wednesday, May 18, 2011

Mikogo is calling for beta testers for their Linux version. The best way I can explain it is an alternative to webex, goto/live meeting or perhaps Bomgar. While not open source it is a free service and anyone making an effort to bring quality applications to the Linux desktop deserves a mention. I believe this is an application that Linux users could really benefit from using (I know I could) so sign up to be a beta tester and give them some feed back that will help them produce a great product people will want to use.

Linux Journal Print Magazines for Sale

Filed under: General Linux — TheLinuxBlog.com at 10:01 am on Wednesday, May 4, 2011

Due to lack of interest, they are now FREE!

If you want to pick them up, if not just cover shipping.

Since I got the Linux Journal archive CD (2007 edition) a few years ago I’m going to get rid of my old ones up to December 2007, Issue #164. I don’t have every issue and they vary in condition, but they’re all in decent shape. If you don’t see an issue listed, the chances are it was either a subscription lapse, I lost it or it was loaned / given away. Anyway here is what I have: April 2005, July – December 2005 (7 issues) January -  September 2006 (9 issues) January – December 2007 (12 issues) Make an offer! I’d rather sell / ship them all at once, but can part with them individually if needed. I have no idea how much shipping would cost but can figure that out. If you’re located in or near Charlotte and are willing to drive, even better we can arrange a pickup, although with gas prices it might cost the same to mail it :). I’ll adjust the list above when they’ve all gone. If I ever get around to buying the 2010 edition DVD my 2008 – 2010 will be up for grabs too. Once I get rid of them I’ll have some more room on my book shelf for future editions or maybe some new books.

Easy Keyboard & Mouse Sharing with QuickSynergy

Filed under: General Linux,Linux Software — TheLinuxBlog.com at 6:30 am on Wednesday, April 6, 2011

I’ve written before about using one computers keyboard and mouse across multiple computers by using x2vnc and x2x, there is however another tool called Synergy. I never really messed around with it because of x2x and x2vnc but it is a valuable tool worth mentioning. QuickSynergy is available in most repositories that is a handy little tool to get your computers set up using Synergy and as the name suggests; quickly. If you apt-yum-get-fu it it will install all your dependencies for you and make setup a breeze.

Take a look at the screenshots:

Remote SSH Port Forwarding

SSH Remote Port Forwarding

SSH is an amazing tool, I often find myself finding new and interesting ways (at least to me) to use it. It is a great tool to have in your toolbox.

This may be hard to explain in works, but here goes.

Picture this: you have 3 hosts, Host A has outbound access only and is on the same network as Host B. Host B has port 22 open, accepts ssh and is allowed to ssh to Host A. Host C is the computer you are sitting at and on a different network. So, you need to connect to Host A from host C. The way to do this is with SSH port forwarding.

Lets say Host A is 192.168.1.2, Host B is 192.168.1.1 and Host C is 10.0.0.1 on the different network. Host C also has port 22 open.

So, in order to connect to Host A from Host C you can do the following with local port forwarding:

linux server management
Management… What more is there to say? Management has the ability to either make your life easier or make your life a living hell, server management can go the same way. With these utilities Linux Server Management doesn’t have to be quite as grim. In fact having the right server management software can be very rewarding. In this post we’ll cover some of the Linux Server Management software that is available. As always, feel free to contribute your favorite tools!

Setting up a VPN with pptpd

Filed under: General Linux,Linux Software — TheLinuxBlog.com at 9:00 am on Wednesday, January 19, 2011

Setting up a VPN with pptpd One of the things that was on my whiteboard for some time was to set up a VPN for home use. Sure, I can do some remote SSH port forwarding, use ssh as a proxy or perhaps even use some Linux Tunneling Techniques but they’re not quite the same as a full blown VPN. You can use the VPN for access to remote services, to secure communications on untrusted networks or use it for mobile devices. Whatever your use its easy to set a VPN up with pptpd that can be used with your mobile and remote devices. (Read on …)

The root for the previously installed system was not found – Fedora

Filed under: General Linux,Linux Software — TheLinuxBlog.com at 12:30 am on Wednesday, January 12, 2011

The root for the previously installed system was not found
I was having an issue with a preupgrade of Fedora, somehow an old package that was no longer in use decided it was going to cause the installation to fail. After rebooting, finding the guilty package and removing it I started the upgrade again. This is where the error message “The root for the previously installed system was not found” occurred.

I did some research, tried mounting the file system then upgrading that way and still nothing.

According to this Fedora Forums post other people have experienced this issue. In cagonto1980′s post it explains the workaround:
Mount the filesystem, vi /mnt/sysimage/etc/fedora-release and change the release to the previous version. You may need to remember the version, mine was set to “Fedora 13 (Goddard)” and I changed it to “Fedora 12 (Constantine)”. After rebooting it started the upgrade. It appears the issue is Anaconda updates the release file and doesn’t change it back if the installation fails causing the next upgrade to think that the newest version is installed.

Thanks to cagonto1980 for the workaround.
