Raspberry Pi 2: Raspbian (ARMv6) v Linaro (ARMv7)

The Raspberry Pi Foundation make it pretty clear that Raspbian is the recommended operating system for the Raspberry Pi series of computers. Most of the Foundation's documentation and support directs users to Raspbian. The downloads section of their website does list other operating system images. But there are many more images available, and one really piqued my curiosity; a Ubuntu 14.10 / Linaro 15.01 "developer" image. Unlike Raspbian, this image is compiled for ARMv7/armhf.

But this "developer" image has no official support. It is not supported by Linaro. Nor is it supported by the Raspberry Pi Foundation; it's not even mentioned in the Downloads section of their website. You see, the "developer" image is created by Toby Wintermute, a software developer who lives in Victoria, Australia. He claims that this image should be quicker than Raspbian.

What is GNU/Linux? Linux is part of a powerful computer operating system that is distributed at no cost as an alternative to Windows or Apple OSX. Many devices from Internet servers to cable boxes to mission critical systems run Linux. Linux is developed collaboratively worldwide by companies and individual volunteers. Linux was started by Linus Torvalds in 1991. The GNU Project was started in 1984 by Richard Stallman, and replaces commercial UNIX software with all free and open source software.

What is Free/Libre open source software? Free and open source software is software whose source code is open and available to anyone who wishes to improve it, study it, modify it, and share the original and the modifications with others.


Delete file when you have more than 100g for deleting

Hello Linix community members,

Today I would like to share a simple script for deleting files when you have more than 100g for deleting and when you try to delete using rm -rm /path/fo/files failed.

To do this I use the following procedure;

first I use a "for" ciclo to read file that I going to delete also you can use a mtime for calculate file's date that you're going to delete or you can to calculate previous date of a past day "x=`TZ=GMT+24 date +%Y%m%d`"


#!/bin/bash -x
x=`TZ=GMT+24 date +%Y%m%d`
for files in `find /path/of/file/to/eraser/ -name \*$x*.bin.gz`
echo "Deleting file $files"
/bin/rm -rf $files
delcnt=$(($delcnt + 1))


Best regards

Raspberry Pi 2 review

The latest chapter of the Raspberry Pi promises so much, but does it deliver? The Raspberry Pi is a series of credit-card sized single-board computers. The original Raspberry Pi was acclaimed by some reviewers as a desktop PC replacement. The reality was vastly different.

With a single core CPU and a 256MB dollop of RAM it was honestly too slow for many typical desktop tasks. It was never a desktop replacement after all. The Raspberry Pi's creators, the Raspberry Pi Foundation, wanted to spark children's interest in computer programming and encourage students to apply for computing degrees. The original Pi, and its later incarnation with 512MB RAM have been a runaway success, selling 5 million units. The charitable foundation has used the proceeds from the project to train teachers, supply educational resources, and fund numerous open source projects.

Using netstat to audit your network connections

There is a number of tools you can use in Linux to see what is going on your machine at the network level, one of the most common is netstat. This command will show you all the connections on your system, including some that you may not be interested in, like UNIX sockets. There are a few flags you can pass to netstat, my favourite set of flags is: -antp

-a all
-n show ip instead of host names
-t show only tcp connections
-p show process id/name

Another command that will give you similar results is: lsof -nPi

What if you wanted to see the 10 ip addresses with the most connection to your server? You could use a one-liner like this one I came up with:

netstat -ant | grep -i establ | awk -F" " '{print $5}' | cut -d':' -f 1 | sort -n | uniq -c | sort -nr | head -n10

Overview of Three Chat Clients for KDE: Quassel, KVirc and Konversation

Internet Relay Chat has a history of over 25 years and it is still a widely used text-based protocol for chatting. In the Linux world, each distribution and major project has a chatting room, usually on Freenode, and here you can get online help, participate in collaborative projects, or just have a look at the latest discussions regarding the development of some project or application.

There are plenty of IRC clients out there for Linux, including console-based ones like the powerful Irssi, graphical ones like XChat, HexChat or the ones embedded in instant messaging clients. There are also web-based ones or clients available as add-ons for browsers, for example the ChatZilla add-on for Firefox.

In the following article I will briefly discuss about three clients for the KDE environment, leaving the others for a future article. All three of them come with features such as tabs, DCC, multiple networks or SSL.
