1. 22 ways to convert your friend to Linux

Are your friends convinced that they should be paying for their operating systems because

Linux sounds too complicated or because they think it won't do what they want it to?

Fear not, here's your guide to brining your friends over to the light side...

1. First you need a non-geek friend

If your idea of getting out is a monthly trip to the local LUG, you need

to cultivate some more mainstream friends before you can start to

convert them. Getting a Fedora fan to use Ubuntu does not count.

2. Don't evangelise

Pushing Linux like it's the greatest thing since sliced bread, or that it's atleast 10 times better than Windows, will have one of two effects. It will

either cause your friends to push back, making it harder to convince

them; or they'll agree to try it but have such high expectations that

they'll feel deceived the first time something doesn't work as they

expect. Be subtle use Jedi mind tricks instead.

3. Drop hints

Instead of pushing, just mention it from time to time especially when

the issue of online security, viruses and malware comes up. Let your

friends' curiosity get the better of them, let them ask you about it, then they'll want you to show

them Linux.

3. Puppy Linux 5.2 Is Based on Ubuntu 10.04

Puppy Linux 5.2 features lots of updated and improved applications, the new Quickset

dialog to easily setup your system (language/locale and keyboard settings, timezone, video

resolution), Browser Installer, Browser-Default, Quickpet, improved Puppy Package Manager, and

a lot more for you to discover.

"Lucid Puppy 5.2 is a Puppy through and through. What

that means is that the *architecture* is pure Puppy--it just

happens to be that many of the building materials

(applications, utilities, libraries) are Ubuntu binaries. With

Puppy founder Barry Kaulers Woof Build System the

packages could just as easily have been Slackware or Arch

binaries."

4. Learn Linux, 101: Runlevels, shutdown, and reboot

In this article, learn to shut down or reboot your Linux system, warn users that the system is

going down, and switch to single-user mode or a more or less restrictive runlevel. Learn to:

Set the default runlevel

Change between runlevels

Change to single-user mode

8/8/2019 fossnews-39

3/9

Free Open Source Software News 3

Shut down or reboot the system from the

command line

Alert users about major system events,

including switching to another runlevel

Terminate processes properly

Unless otherwise noted, the examples in this article

use a Fedora 8 system with a 2.6.26 kernel. The

upstart examples use Fedora 13 with a 2.6.34

kernel, or Ubuntu 10.10 with a 2.6.35 kernel. Your

results on other systems may differ.

This article helps you prepare for Objective 101.3

in Topic 101 of the Linux Professional Institute's

Junior Level Administration (LPIC-1) exam 101.

The objective has a weight of 3.

5. Switching to Linux (For the Right Reasons)

.

Why are you using Linux on your desktop?

Before answering this question, consider the advantages and disadvantages and then come back full

circle to your own motivation for using Linux. Nearly every week, I find my news feeds filled withthe usual generic articles describing rather vanilla reasons for using Linux on the desktop.

Why do I have a problem with this? Perhaps because

the reasons often being shared are just echoes of other

opinions that clearly aren't that of the author. Instead,

we are reading the thoughts and ideas of many articles

since past.

Great platform for the wrong reason

Take, for example, promoting Linux as the malware-

proof OS. Sorry to break this to you, but this doesn'texist. Or my personal favorite, Linux means you never

need to upgrade your hardware.

Reasons.htm

6. Blender 2.56 beta released Update

The Blender Foundation and associated online developer community have released Blender

2.56 Beta, the fourth official beta release of the Blender 2.5 series. On final release thisdevelopment code will become Blender version 2.6.

8/8/2019 fossnews-39

4/9

Free Open Source Software News 4

This beta is for the most part feature complete and over 440 bugs have been fixed since the 2.55

beta, although a very bad bug in "undo" for the Cloth / Fluid sim was discovered the day after the

initial release. This bug has now been fixed and the

developers say they will probably release a 2.56a update

including the fix, soon.

The developers say there have been extensive changes in

the Python API, most notably in naming conventions and

in the creation and access of properties. They also point

out that extensive renaming operations between version

2.53 and 2.56 have considerably changed the scripting

API; this effects loading 2.53.blends with animation into

2.56. Users are also instructed to try the FCurve / Driver

2.54 fix entry from the Help menu.

7. Configuring PostgreSQL for Pretty Good Performance

PostgreSQL is a highly customizable relational database management system (RDBMS)

with a dazzling array of configuration options. Fortunately, especially in recent versions of

PostgreSQL, most of these settings do not need to be changed. The trick is to figure out which

options do need to be changed and what values are most appropriate.

A few minutes spent adjusting your postgresql.conf file can result in major performance

improvements. Further improvements may be possible with sufficient time and thought, but in thisarticle I'll focus on how to quickly get your settings into the right ballpark.

One of the most important methods of improving PostgreSQL

performance, especially on large data sets, is to increase the

parameter shared_buffers, which controls the amount of memory

PostgreSQL uses for its private buffer cache. Because

PostgreSQL also makes use of the system buffer cache, and for

other reasons, experience has shown that it's usually best to set

this parameter to about 25% of system memory on UNIX and

Linux systems, but not more than about 8GB. (Sometimes 8GB

is already too much.)

8. Android tablets sweep CES 2011

As with last year, this year's Consumer Electronics Show (CES) taking place in Las Vegas is

nearly all about the latest and greatest Android devices, specifically tablets. Many of the newly

announced Android tablets will reportedly run recently confirmed next major update to Google'sopen source Android mobile operating system, Android 3.0 code named "Honeycomb".

Previewed by Android chief developer Andy Rubin at the D: Dive into Mobile technology

conference in San Francisco last month, Motorola officially announced its XOOM Tablet. The

XOOM features a 10.1-inch widescreen HD display, a

1 GHz dual-core processor, and built-in 3G and 4G

LTE support for US CDMA mobile phone carrier

Verizon Wireless. Otherspecs include a 5 megapixel

camera capable of 720p HD video recording, 802.11n

Wi-Fi, Bluetooth 2.1+ EDR and 32 GB of on-board

storage. The XOOM is expected to launch in the first

quarter of 2011 with an upgrade for 4G LTE arriving

in Q2 ahands-on video is available from Engadget.

9. Drupal 7 Integrates Modules to Open Source CMS

The latest version of the Drupal content management system, integrates several popular

modules that were previously separate from the core system.

The Obama administration has been by far the most aggressive adopters of

open source technology compared to previous administrations. One of those

open source tools has been the Drupal content management system (CMS),

used to run the Whitehouse.gov site. It's a system that's also proved popular

among a growing number of startups, smaller companies and enterprises.

Now, as Developer.com reports, the company behind Drupal has unveiled a

new version that integrates what used to be separate modules and adds new

Semantic Web features.

10. Linux 2.6.37 Kernel Promises to Unlock OS

Linus Torvalds is starting 2011 off with a bang with the release of the 2.6.37 Linux kernel.

The new kernel is the first release since 2.6.36 debuted in October.

The goal of the new 2.6.37 kernel is to providedevelopers with improved Linux performance,

security and scalability.

From a performance perspective the 2.6.37 kernel

removes the Big Kernel Lock (BKL). The BKL is a

legacy part of the Linux kernel that has now been

fully supplanted by more modern and efficient

locking mechanisms for kernel processes.

11. Virtualization With KVM On An OpenSUSE 11.3 Server

This guide explains how you can install and use KVM for creating and running virtual

machines on an OpenSUSE 11.3 server. I will show how to create image-based virtual machines

and also virtual machines that use a logical volume (LVM). KVM is short for Kernel-based Virtual

Machine and makes use of hardware virtualization, i.e., you need a CPU that supports hardware

virtualization, e.g. Intel VT or AMD-V.

I do not issue any guarantee that this will work for you!

1 Preliminary Note

I'm using an OpenSUSE 11.3 server with the hostname server1.example.com and the IP

address192.168.0.100 here as my KVM host.

We also need a desktop system where we install virt-manager so that we can connect to thegraphical console of the virtual machines that we install.

I'm using an OpenSUSE 11.3 desktop here.

2 Installing KVM

OpenSUSE 11.3 KVM Host:

First check if your CPU supports hardware virtualization -

if this is the case, the command

egrep '(vmx|svm)' --color=always /proc/cpuinfo

http://www.howtoforge.com/virtualization-with-kvm-on-an-opensuse-11.3-server

12. Understanding Linux File Types

You can use the ls -l command to see the various types of files.In the following example,

the first character in the output is a -, which indicates that its a regular file.

ls -la /var/log/messages

-rw- 1 root root 204909 Jun 5 10:50 /var/log/messagesThe next example shows that it is a directory as it starts with a d.

ls -ld /etc

drwxr-xr-x 105 root root 04111 Jan 5 08:36 .

File Type Encoding When Using ls

Regular file-

Directory d

Character Device c

Block Device b

Local Domain Socket s

Named Pipe pSymbolic Link l

Device files facilitate the communication between hardware and software. The kernel manages

modules that know how to communicate with system devices. These device drivers create a

standard method of communication with the hardware. They look like regular files. When the kernel

receives a request for a character or block device it contacts the right device driver to take care of

the communication.

13. KOffice 2.3.0 Released

The KOffice team is happy to announce the 2.3 release of KOffice. This release brings many small

improvements to all the KOffice applications, but not as many large new features. Among the most

important new features are:

Krita is now ready for professional artist use. This is thanks to the

very focused effort by the Krita team after a meeting which

resulted in a clear vision and well defined goals. More details are

available in Krita 2.3.0 announcement

A new slide sorter view in KPresenter, which has been greatly

missed by some users. There is also a new shape animations

feature for KPresenter.

Improvements of the core engine and plugins in the support of the

OpenDocument Format. Especially text rendering has seen much

work. Even more improved support for reading Microsoft file formats (doc, xls, ppt, docx, xlsx, pptx).

A new report engine used in KPlato and Kexi.

14. Why I am still supporting Free Software?

Today I was debating with a friend the relevance of Free Software, he pointed that at the

current development rate is very unlikely that Linux (most

common Free Software subject) will have a significant endusers market share in 50 years. I remembered him that

Linux powered devices already a significant mobile market

share. He noted that most of the mobile users do not care

or do not know that they use a Free Software powered

mobile phone I had to agreedon this.

Later today while providing some answers at

askubuntu.com I have kept this debate on my head and

asked myself, why I am still supporting Free Software ?

When I started getting involved in free softwaredevelopment, about 15 years ago, I was a young

programmer wanna-be, I was eager to learn all these bunch

8/8/2019 fossnews-39

Free Open Source Software News 8

of languages, protocols, libraries, etc. As if it wasn't good enough I could even get help and help

other people, which I always loved to do. I never managed to get a job with free software/open

source (and probably will never do) but despite having a good job I always felt that working and

programming with free software was closest to what I love doing, knowledge sharing.
