kmousetool and dragon naturally speaking for RSI

I'm currently using windows 7, but I am seriously thinking of switching over to linux.  Ubuntu seems like a good place to start and seems to be one of the most popular distributions.  Like a lot of people I'm becoming increasingly unhappy with windows, especially the support for XP ending, and the complete mess up of the start menu in windows 8.  I'm also looking at installing on my mother's 10 year old laptop, as that has really slowed down after the support ending for XP.  But my mother is not in any way technical like myself.

There are one or two sticking points for me though.  I have repetitive strain injury and currently use nib autoclick software.  I've been looking at kmousetool and managed to get left click right click and double click working OK, but can't seem to figure out the click and hold.  Also once I've got the programme started and running in the background, I can't get the settings up.  Do you have to leave the settings page open while you're using the program?  I would also like to know how easy it is to highlight text using the click and hold?

The second thing is using dragon naturally speaking in wine.  How easy is this to install?  Can the speech recognition be opened quickly and the text copied and pasted from the dragon pad in wine, to the main desktop environment?  I've had a look on the wine forum and version 10 seems to work the best.

Just one more thing when you install software that is outside the main software centre, like skype for example, does that slow things down and do any upgrades come from the software centre or would they come from skype?

Thank you for your help







Make Your Linux Machine a Virtual Router

I've written a boatload of Linux articles over the years. Not a big boat, mind you, but a boat nonetheless. Today, I'm going to tell you something important. Linux has reached a stellar of badassery and here's why. Not only do we get a free, open and customizable system, but we can also use our computer as a virtual router. Here's how:


1) Open terminal and type the following command

sudo add-apt-repository ppa:nilarimogard/webupd8

2) Now, type:
sudo apt-get update

3) Finally, we can install ap-hotspot
sudo apt-get install ap-hotspot

4) Configuration time, baby!
sudo ap-hotspot configure

If you're connected to an Ethernet cable, it should detect your network as something like etch0 -- just continue. Once it asks to name your network, name it something like awesomenetwork. Your WPA password should be of the following length (this is what I use as my password: fivefifty. No longer, no shorter. 

Here are a couple of commands to stop and start your router.


5) Start router

sudo ap-hotspot start


6) Stop router

sudo ap-hotspot stop


7) Restart router

sudo ap-hotspot restart


25 things to do after installing Xubuntu 14.04 Trusty Tahr

Xubuntu 14.04 Xubuntu is a great distro, that combines the great Xfce desktop with the great Ubuntu. It presents the conventional desktop with a pleasant and rich looking user interface. Its fast and less resource intensive compared to Gnome shell, unity and kde variants of ubuntu. Xubuntu 14.04 has just been released the same day with Ubuntu 14.04. So go ahead to install it if you prefer less of KDE and dislike ubuntu's unity desktop.

Open Source Textbook Podcast

The idea is to take an Open Source Textbook on mathematics, physics, chemistry or biology and make an Linux style inspired podcast series. Here two or more people discuss the theory on each of the topics, problem solving techniques, its applications and more.

Even if this is a podcast you can have visual content. Just add links to images/videos referenced in the podcast to your web page. It should make it less expensive then to do a pure video podcast.

I think following a podcast for your textbook where they ask interesting questions, where you can learn from good explanations or maybe just get motivation from a fun session could go a long way.

How to fix “System program problem detected” error on Ubuntu

The error "System program problem detected" comes up when a certain application crashes. Ubuntu has a program called Apport that is responsible for detecting such crashes and upon user consent, report these crashes to developers. This process intends to get the problem fixed by the developers. However it can be very annoying to common users, and there is no point in showing errors to users when they cannot do anything about it themselves. So you might want to disable them. Remove crash report...

Boosting VPS Performance : Tips For Enhancing Server Speed

The virtual private server (VPS) technology provides with significant affordability for both – the web hosting company and the end customers. A VPS hosting platform provides with privacy and security similar to a dedicated server environment without the expenses of renting an entire server. As a result of this, the end users can enjoy the best of both worlds! The VPS hosting services reduce many issues that are associated with the shared servers including the system slowdowns caused as a result of the users on the servers. In case of a VPS, the resources allocated to a particular user are always reserved for the sole purpose of that user. This helps in reducing the downtime, prevents the occurrence of unnecessary lags and improvises on the overall performance of the system. In order to improve the VPS hosting performance even further, you need to know some important tips that will help you to optimize the speed and performance for both Linux and Windows VPS platforms.

Monitor The Performance

It is important to track the speed and performance of the applications hosted on the virtual private server for ensuring optimum performance. At times, the software conflicts might result in slowdowns. Other reasons for poor performance include insufficient space and processing resources, hardware errors or bandwidth issues either at the source or in case of the end user. Detecting these problems early can help in improving the productivity and avoid unnecessary website slowdown or downtime that might occur if these issues remain unaddressed. In some cases, increasing the storage space through the VPS host might be the perfect solution. The cost of increasing the resources is usually less than lost revenues incurred as a result of delay in taking the right decision at the right time.

Improving Apache Performance On VPS Servers

In case of Linux implementations, it is better to opt for dynamic module management instead of static. The resident web server module loading settings can help in improving the overall performance in the VPS environment. This is possible because the dynamic module loading enables the components to run only when they are actively required. These setting utilize less server resources and provides with better speed and performance for the applications hosted on the server. This is an important attribute in case of servers that operate MySQL or other programs that need large volume of server resources. Moreover, if you install and maintain only the main Apache functions and components and eliminate the less useful elements, you will be able to successfully improve the overall VPS performance. Disabling some parts of Apache’s in-built functionalities can also result in improving the loading times and improve on the overall performance of the VPS platform.

Managing MySQL’s Memory Usage

For the companies that utilize MySQL, optimizing the database implementation is important for ensuring faster page load times and improved performance. MySQL is often paired with the Apache software. This combination might create significant slowdowns in the limited resource VPS platforms. It is crucial to ensure that the dynamic durability settings for MySQL are enabled. In this way it is possible to enhance the speed and processing power of MySQL database. Moreover, by reducing the key buffer size to the smallest possible percentage might free the valuable system resources in the MySQL environment. This will boost the page speed and performance for the page loads and other applications. In some cases, you can even consider moving the database server on a separate server altogether.

Streamlining The Performance

Many Linux VPS hosting providers offer a wide range of re-installed applications for the initial implementation service. For the companies that don’t need to use these applications, removing them from the server can free the space thereby providing a faster and streamlined VPS environment for important applications and data storage requirements. Streamlining the Apache web server applications, MySQL database and other components present under the VPS server environment will help in boosting the VPS performance. It will also be possible to manage the expenses and space availability in an efficient way, enabling the companies to achieve higher productivity and increased revenues without spending a huge amount in server storage space for doing so.


Schedule Your Jobs in Linux With CRON

    Most of the Linux users are aware of how commands are run, processes are manipulated and scripts are executed in terminal. But, if you are a Linux system administrator, you might want them to start and execute automatically in the background. As an example, you might consider running a backup job every day, at a specific time, automatically. Or you might consider an example of collecting inventory data of the systems deployed across your network, by running a script automatically on monthly basis. But, how to schedule these jobs and execute them automatically in Linux?

    There is an utility in Linux known as CRON with which you can start your jobs automatically at a desired time and schedule them to get executed periodically.

    Cron utility consists of two parts: The cron daemon and the cron configuration files. Cron daemon is just like any service that is started automatically whenever your system boots. Cron configuration files hold the information of what to do and when to do. The main job of cron daemon is to inspect the configuration regularly (every minute to be more precise) and check if there is any job to be completed.

    In the /etc directory, you will find some sub-directories namely cron.hourlycron.dailycron.weekly and cron.monthly. You can put your scripts in these directories, and as their names suggest, they will be automatically executed after certain period of time. For example, if you wish to run a job or service regularly after every week, simple put the script in /etc/cron.weekly directory.

In case you need to execute a script after every fortnight, keeping the script in any of the above mentioned directories will not help. But, every problem has a solution. You can launch crontab (CRON TABle) editor which provides an interface that is very much similar to vi editor using the command crontab –e. This will start the crontab editor to create cron job for the root user. If you are root and you wish to create cron job for other user, you can use command like crontab -u [USER] -e.
