Here's a conversation Skip Guenter had with a friendly neighbor last week.

"So anyone can come in and use those computers?"

"Sure, but students have priority."

"What if I don't want my daughter exposed to perverts? How can you make sure that doesn't happen?"

"We can seat her at a computer without an Internet connection."

"Well, how is that supposed to keep perverts away?"

Apparently, the perverts live in the computer. It also apparent that we have our work cut out for us.

One thing that keeps Linux in the back foot is the lack of good quality applications that can compete with the best out there. The advent of paid softwares section in Ubuntu Software Center is a start, things like that can kick start application development for Linux in a big way. But things were not as bad I thought it would be. On further browsing, I found out that there are indeed a good number of paid applications for Linux, some of them were a total surprise for me. Here are some of those paid applications for Linux which I found interesting.

Ever since I got my HP probook 4420s I have been on a search for the Touchpad (or Clickpad as it is called) Nirvana. On Kubuntu 10.10 Out of the box the clickpad was basically useless, right click and middle click did not work. Thankfully though, a work around helped get the most basic functionality working, but lacked multi-touch (even though the clickpad supports multi-touch) Another patch was released which gave clickpad multitouch support but removed right click option (You have to do a 2 finger tab to right click)

Powerful companies like Google and VMware are fighting for a chance to be the enterprise front end to the Cloud. There is a battle going on in the Cloud and it's happening whether it's a private cloud or a public one. That battle is for the soul of your cloud front end. It's nothing more than a web page, a portal if you will, that acts as a single point of control and access, but vendors like Google and VMware are fighting hard for your loyalty.

Scott Crenshaw: "Pundits around the industry are using the repeated – and successful -- attacks on Sony’s Playstation Network as proof clouds aren't secure. But what's 'cloudy' about PSN?"

To help us celebrate the 100th issue of Linux User & Developer, Ubuntu founder, Mark Shuttleworth, agreed to take the reins from our regular Ubuntu columnist (Dave Walker) and take us through why he believes it was the right decision for Ubuntu to embrace the future with Unity…

At work we use a lot of Firebird databases, and so far our system admins checked the availability of a Firebird Database by simply trying to connect via telnet to the port 3050 and see if they would get a response.

Syncany is a brand new open-source file sync software (similar to Dropbox, or Sparkleshare). "Oh no, not another Dropbox alternative" you might say. Well Syncany is different and has the chance to become better then other such applications. Read on!

This article describes how you can upgrade your Fedora 14 system to Fedora 15. The upgrade procedure works for both desktop and server installations.

Time to be honest here for a minute. The open source community really has outdone themselves coming up with some very obscure names for packages. Let's take this list of packages for instance: emacs, gimp, gcc, mutt, grub, kyle rankin, parted, tar, mutt, vim. Nine times out of ten, a common person is going to look at that list and become utterly confused over what package does what. That's just the beauty (and beast) of naming software in the open source community. But every so often a tool comes across my screen with such a blatantly obvious name that I just have to run a 'man' to make sure my eyes are not deceiving me. In this case, it's ethtool. Yes, a simple name, for such a powerful utility. The name itself tells you what it does, an Ethernet Tool. Tada! That's it, ethernet tool.

digiKam makes it relatively easy to tag photos. Select one or several photos, expand the Caption/Tags right sidebar, tick the tags you want, and press the Apply button. You can also assign keyboard shortcuts to the often-used tags to speed up the tagging process.

Having suspended disbelief for as long as I could, my ability to take Microsoft at their word over Skype was shattered yesterday on hearing the announcement by Digium, sponsors of the widely-used Asterisk VoIP project, that they have been told they can no longer sell their Asterisk-Skype interaction module after July 26. That means it will become impossible for this VoIP PBX to connect to Skype.
