Amarok 1.1 review

Neoteksystems, on 28 September we have come a long way with our music players in KDE. Of xmms, Noutan, Juk, and Amarok... but the progress now was a good?

by Neoteksystems

I've been a loyal user KDE for some time now. I started at the time 1.x on Redhat 7 (I think... can't remember if I used KDE with Redhat 6). From Redhat 7, 9, for now Gentoo Mandrake I saw KDE through all its changes. One of the arena of software that KDE has seen much growth (and is in no way the only area) are in the field of audio coach. In the early days, I've used xmms and freeamp. They were mearly although audio players and were not really designed to handle my digital audio collection (playlists just don't cut it!). The first backward here is that they were not native KDE pro rata, so that they felt place with all my other KDE pro rata. After some time, KDE has led a Noatun at the table. Noatun falls into many of the same category as xmms, but this time it was a real KDE application and "adjustment" with the rest of my stuff. There is a problem though, my digital audio collection grew and I needed something to really help me manage this growing collection. In response to this need KDE which we JuK. It is a step in the right direction, it could keep track of your entire collection, but it is still largely based on the idea of a playlist for separating your audio output. While this might not a big problem a few years, other houses major software began offering applications very strong to manage our audio collections. Apple comes out with iTunes and it basically rewrites the rules for how we treat our digital audio con. It is very fast and easy to find your music based on artist, album, genre or any number of other criteria. Microsoft has continued to update Media Player and with the version 9 (and now 10) brought us a tool to manage our collection of any media (now included video). WinAMP has continued to make progress, and with version 5 introduces a new media viewer which allowed iTunes like sorting and separating it quickly on certain criteria. It was time for KDE to bring a real coach to the table... Enter Amarok.

This editorial that amarok is version 1.1, and this is my first time to get to use it. Right off the coast of the bat, I can say that I am very impressed. I simply said he what folder has all my music in it and it very quickly catalogued everything and I was ready to begin listening for and manage. You are first presented with your collection in the left pane and can quickly create a playlist for an artist full collection or only certain albums/songs from there. Your current playlist is always shown in the right pane. Once you are in fact listening to songs the left pane can change a window of information on the song, album and other tracks by the given artist.

Benchmarks: Doom3 on machine AMD3000 + with a tested on Windows NT and Linux Nvidia Gainward graphics card

LinuxReviews.org benchmarks show that Windows XP outperforms Linux on the same material and same official Nvidia drivers. Windows XP was simply a better job to run games on this configuration.

The tests are carried out by Michael Taoushanis

The tests were conducted with Windows XP version 66.81 and Gentoo Linux using X.Org version 6.8. The two operating systems have received the official Nvidia drivers. The figures show clearly more frames per second when using Windows XP, even if numbers should ideally be the same, numbers higher on both operating systems.

The protocols of the future of BitlBee, the IRC gateway for instant messaging (MSN, ICQ, Jabber, Yahoo)

LinuxReviews.org interview with the developer team BitlBee: Wilmer van der Gaast, Maurits Dijkstra and Jelmer Vernooij and a Word from the old Sjoerd Hemminga developer. Discover what new cool features will be available in version 1.0, which includes have been implemented so far and what visions these brilliant young men have for the future of BitlBee and the Open Source community.

What is BitlBee, and what makes it so cool? What steps has the BitlBee recently overcome, including the star in the new version you are more satisfied? BitlBee was originally written for Linux. How much work was involved in porting of Windows, and why did you choose to do so? Can what major new features we expect in the next version of BitlBee? What awaits us? A survey on the bitlbee.org showed 58.1% of your transfer of files users doas was their most desired functionality. When BitlBee will support the transfer of files? What other projects are open source you involved in? What are your future visions for BitlBee? What are your visions of the future for the Open Source community? Why is what made you leave BitlBee? More information on BitlBee

1. What is BitlBee, and what makes it so cool? Wilmer: BitlBee allows to talk to people on Jabber, ICQ, MSN and some other IM networks using your favorite IRC client. Several programs such as BitlBee already exist, but most of them either are supported only a single network IM or IRC client. Why is this cool? For me it's cool because I like the way of works my (irssi) IRC client, and because it allows me to keep all my tricks of communication (e-mail, IRC, IM), running in a session of the screen and attach to it from anywhere. But BitlBee seems to be popular in other groups. For example, many fans of Emacs uses Bitlbee

Type faster by learning touch

v1.0, touch LinuxReviews.org allows to quickly increase your typing speed once you learned the basics.

How learn to type touch effectively on Linux look at the screen, not the keyboard!

The touch method is probably the technique for more typing fast on the standard keyboard available today. Dry theory is very simple: the fingers of the left hand should rest with the asdf keys, the fingers on your right hand should rest with jkl; All other keys should be pressed by moving fingers, down, left and right.

1. How to learn to type touch effectively on Linux

There are several specially made programs to teach you how to type fast on Linux, but it stands as the best thing for the moment created: Ktouch, a part of the educational KDE (kdeedu) package that comes with the KDE desktop environment. You are probably already installed program if your distribution includes KDE. It is likely that it is available with your distributions package manager if you have not installed it. Start by running the command ktouch.

Why Copyleft is important for the human species as a whole

Linuxreviews.org GNU Copyleft copyleft is designed for programs, but it can be applied to any type of intellectual property: texts, images, video and other types of works as well. Copyleft ensures knowledge remains a free part of the Commons and is a very effective way to regain control of knowledge and thought which now belonged to private companies.

What is copyright? How Open Source Software is changing Beat Copyright by licence 3.1. The Free software foundation 3.1.1. Copyleft 3.1.2. General Public License 3.2. BSD-style: The "good luck" license 3.3. Private property of Creative Commons Attribution 2.5 v.s. Public

The human species is estimated to have had the same amount of intelligence thousands of 250,000 to 300,000 years. Humans exploited for iron in Afrika approximately 90,000 years, which means that the people of the time had organized enough companies. Yet we know little or nothing about these people today.

Human knowledge has been historically been shared as free as possible. At the great library of Alexandria, it was usually just to copy and distribute the books and other documents. The distribution of art and knowledge is limited to available technology very, very long time.

1. What is copyright?

Then about three hundred years ago the human species between the period of time which began the current unsustainable failure of a society with the industrial revolution. It introduces a fundamental change in the sharing of knowledge: copyright has been introduced.

Copyright allows essentially to real and artificial legal persons, immortal called the Corporations to claim a particular work be intellectual property. The concept of intellectual property is a single entity the right fully to control intellectual work. Thoughts expressed have been put on the market to be sold and purchased as goods and services.

It is good for greedy society and their bottom line, but limits the amount of left of common knowledge in the Commons. Copyright steals the common wealth and the place in the private fortune closed and restricted.

2. How is changing Open Source Software

Open Source Software is licensed in a way that places the property of the source code of software in the Commons. Everyone is allowed to use free software, and anyone with the time and skills can participate in its development. This makes software OSS evolve, because everyone using of it becomes a potential developer. Free software continues to evolve even if the original creator leave the project because anyone can pick up the torch and continue.

3 Fight Copyright by licence

The simplest way to make anything free is to place it in the Public domain. A work is free if the owner of the copyright law says that it is. Most countries have laws which, by default, gives the creator of the copyright, therefore it is the owner of the copyright if it wants to share with the world, or not.

Public domain has a problem: it is allowed to take something in the public domain, edit and claim a Copyright on it. This remains a problem as long that copyright is not abolished for the collective good for all humanity.

The licenses have been introduced to deal with this problem. A jungle of licenses have emerged and they all deal with this slightly differently.

3.1. The Free software foundation

Free software is a matter of freedom: people should be free to use the software in all the ways that are socially useful. Software differs from material objects, such as chairs, sandwiches, and gasoline - it can be copied and changed much more easily. These software opportunities as useful it is. We believe that software users should be able to make use of them.The Free software foundation are the creators of the two most popular licenses used today for the common wealth:

3.1.1. Copyleft

Copyleft is a large license originally designed for software that can be applied to images, text, images and any other work elsewhere. The said license the work is free and must remain free. You can do what you want to work as long as it remains in the Commons. You cannot take a picture of Copyleft and put on a Web site that has a notice of copyright to restrict others to freely use the image, but you can use it if you do not use Copyleft yourself.

Copyleft is also a very good idea for the music. Most so-called "samples" used to create modern music are the property of large companies who insist that you buy their music with a pollutant, non-durable media called DVD disks. Copyleft music can be distributed freely, meaning people will promote your music of bands for the millions of people free of charge for you.

3.1.2. The general public license

The licenses for most software are designed to take away your freedom to share and modify. By contrast, the GNU General Public License is intended to guarantee your freedom to share and change free software - to ensure that the software is free for all its users.

It is the most open license software is the property of today.

The Linux kernel, the KDE desktop, Gnome desktop, and thousands of other OSS programs are authorized under the general public license. Using the GPL gives creators and the common a better capability to attack successfully greedy corporations who use the code Commons without giving what to return.

The Best Open Source Graphics And Design Software

A few years ago Novell conducted an online public survey to determine which MS-Windows apps need to be ported on Linux desktop. Adobe Photoshop and other graphics application that user want ported to Linux. However, Linux comes with the sheer numbers of open source software projects produced by the community. You may overwhelmed by the choices available under Linux and not know where to begin.
This blog post covers Vector-based editors, Raster-based editors, Photo editing, Specialty, Desktop publishing (DTP), Web design, 3D modeling, Animation Typography and other softwares:

Even when looking at just a subset -- such as graphics applications -- if you are not already familiar with the options, the volume can make it hard to track down the application that fits your needs. The major categories tend to break down the same way, however -- just a few major players; the large projects often catering to slightly different design goals, and a second set of smaller projects each of which has a smaller team and a more narrow focus.

Let's examine each design field in turn. We'll start by describing the leading program or programs in each, followed by the smaller or younger projects, and end with the special-purpose tools.

Top 5 Open Source Linux Server Provisioning Software

Server provisioning is nothing but load the Linux or UNIX like operating systems automatically with actual operating systems, device drivers, data, and make a server ready for network operation without any user input. Typically you select a server from a pool of available servers, load the operating systems (such as RHEL, Fedora, FreeBSD, Debian), and finally customize storage, network (IP, gateway, bounding etc), drivers, applications, users etc. Using the following tools you can perform automated unattended operating system installation, configuration, set virtual machines and much more. These software can be used to install a lot (say thousands) of Linux and UNIX systems at the same time.

Kickstart

From the official Redhat guide:

Many system administrators would prefer to use an automated installation method to install Red Hat / CentOS / Fedora Linux on their machines. To answer this need, Red Hat created the kickstart installation method. Using kickstart, a system administrator can create a single file containing the answers to all the questions that would normally be asked during a typical Red Hat Linux installation. Kickstart provides a way for users to automate a Red Hat Enterprise Linux installation.

Kickstart Configurator allows you to create or modify a kickstart file using a graphical user interface, so that you do not have to remember the correct syntax of the file.

Open Source Photography Software

I recently brought Canon EOS 500D mid-range DSLR cameras with good promotional discounts. My photography interests date back to my school days but I did not take photography seriously until recently. Now, I'm researching for quality open source photo-software which may be available to photographers. This blog post gives a quick and dirty view of the different photo applications available for Linux operating systems:

Photography on the free software desktop has come a long way in recent years. All of the major desktop environments support camera import and provide image management and editing applications, including the all-important raw file conversion. But the desktop defaults are really geared towards casual users, optimized for point-and-shoot cameras and sharing photos online. Don’t be fooled by that, though; open source can and does offer the tools to support professional photographers and high-end enthusiasts.

Rather than drop in a long, bulleted list of applications, though, let’s take a look at what the open source alternatives are, task-by-task, to get a better feel for how the pieces fit together into a normal photographic workflow.

Ubuntu Linux: Install RT2870 Chipset Based USB Wireless Adapter

This blog post listed Linux Compatible USB wireless adapters. It seems that many new Linux users frequently have problems learning how to install RT2870 driver under Linux. I also received email requesting installation instructions for the same device. This quick tutorial will explains how to install RT2870 based chipset device with WPA2 authentication and TKIP wireless encryption.

Our Sample Setup

The following instructions are tested on:

Ubuntu Linux 10.04.1 LTSKernel - Linux 2.6.32-24-generic-pae i686 (32 bit)WPA2 with Linksys 160N router RT2870 Chipset Based Devices Are Not Working Out Of Box

The main problem is conflicting driver which are shipped with default kernel. WPA2 is a method of security wireless networking with optional PSK for home users. The default driver only recognizes driver but always failed to join WPA2 based network. The solution is to install RT2870 driver from the vendor site.

Step #1: Disable Default Drivers

Type the following command to black list default drivers:
$ sudo vi /etc/modprobe.d/blacklist.conf
Append the following driver names:

blacklist rt2800usbblacklist rt2x00libblacklist rt2x00usb

Save and close the file. Use the rmmod command to remove current drivers or just reboot the system:
$ sudo modprobe -r driverName
# you need to remove all of the above drivers one by one:
$ sudo modprobe -r rt2800usb
OR simply reboot the systems:
$ sudo reboot

Step 2: Install Compilers

Type the following command to install required packages so that you can compile source code:
$ sudo apt-get install build-essential fakeroot dpkg-dev
Finally, install Linux kernel headers so that you can compile kernel device drivers:
$ sudo apt-get install linux-headers-$(uname -r)

Step #3: Download Driver

5 Best Linux Distribution With No Proprietary Components

Linux is a free and open source operating system. However, Linux (and other open source operating system) can use and load device drivers without publicly available source code. These are vendor-compiled binary drivers without any source code and known as Binary Blobs. Die hard open source fans and Free Software Foundation (FSF) recommends completely removing all proprietary components including blobs. In this post I will list five best Linux distribution that meets the FSF's strict guidelines and contains no proprietary components such as firmware and drivers.

Top 5 Reasons to Avoid Binary BlobsModification & distribution - Binary blobs can not be improved or fixed by open source developers. You can not distribute modified versions.Reliability - Binary blobs can be unsupported by vendors at any time by abandoning driver maintenance.Auditing - Binary blobs cannot be audited for security and bugs. You are forced to trust vendors not to put backdoors and spyware into the blob.Bugs - Binary blobs hide many bugs. Also, it can motivate people to buy new hardware.Portability - Binary blobs can not be ported on different hardware architectures. It typically runs on a few hardware architectures.Look Ma Not Just Free Software!

The following are not just a distribution but offers additional benefits too:

Learn how a distribution works on the inside.Ease of use.An active community providing quick and helpful support.#1: gNewSense

gNewSense is a GNU/Linux distribution based on Ubuntu Linux. However, gNewSense v3.0 will be based on Debian instead of Ubuntu. The current version is same as Ubuntu, but with all non-free software and binary blobs removed. The FSF considers gNewSense to be a GNU/Linux distribution composed entirely of free software.

Linux Advanced Hardening With the Capability Bounding Set

The last time I wrote about basic "Linux Server Hardening Security" tips. In this post I will write about the /proc/sys/kernel/cap-bound file which act as a powerful Linux hardening tool. This file holds the value of the kernel capability bounding set (expressed as a signed decimal number). This set is ANDed against the capabilities permitted to a process during exec. You can make changes to this file (bit value of cap-bound) and you can restrict many capabilities of process and put restrictions on root related process too. Using capability you can enable or disable Linux kernel modules loading, firewall, routing, raw sockets, locking of memory segments, restrictions on changing file ownership, restrictions on read and search of files and directories, sending signals to processes owned by others, modification of immutable and append-only file attributes, use of chroot(), rebooting the system, conman sys admin tasks such as mount, quotas, swapping and much more.

How Do I See Default or Current Capability Values?

Type the following command:
$ cat /proc/sys/kernel/cap-bound
Sample outputs:

-257How Do I Set New Capability Values?

Use the echo command as follows:

 echo 0xHexValue > /proc/sys/kernel/cap-bound 

The bounding set is expressed as a bitmask so you can use hexnumber or use bash shell left bit bitwise shifts ARITHMETIC EVALUATION operators. A word of warning - be very careful when making changes to the bounding set. You may end up locking the system due to wrong values.

Example: Stop Loading Modules (Drivers) After System Has Booted

The CAP_SYS_MODULE allows to insert and remove kernel modules without limit. The capability number is 16 for CAP_SYS_MODULE. So you can use bash shell left bit bitwise shifts as follows to disable loading of drivers as follows (you must be root user):

 echo 0xFFFEFFFF > /proc/sys/kernel/cap-bound 

Now try to load or unload modules:
# modprobe ide_cd
Sample outputs:

FATAL: Error inserting ide_cd (/lib/modules/2.6.18-194.3.1.el5/kernel/drivers/ide/ide-cd.ko): Operation not permitted

OR try to remove module:
# modprobe -r cdrom
Sample outputs:

FATAL: Error removing cdrom (/lib/modules/2.6.18-194.3.1.el5/kernel/drivers/cdrom/cdrom.ko): Operation not permittedHow Do I Make Changes To Capability Permanently?

To make changes to /proc filesystem permanently, add them to /etc/sysctl.conf file:
# vi /etc/sysctl.conf
Append the following line:

 # Do not load or remove any kernel drivers# Clear bit # 16echo 0xFFFEFFFF > /proc/sys/kernel/cap-bound 

Save and close the file. Load changes:
# sysctl -p

How Do I Find Out List Of All Supported Capabilities?

To get an overview of Linux capabilities and its numbers see /usr/src/linux/include/linux/capability.h file, enter:
$ vi /usr/src/linux/include/linux/capability.h
OR use the grep command to find out numbers quickly:

 grep '#define CAP' /usr/src/linux/include/linux/capability.h 

Sample outputs:

#define CAP_CHOWN 0#define CAP_DAC_OVERRIDE 1#define CAP_DAC_READ_SEARCH 2#define CAP_FOWNER 3#define CAP_FSETID 4#define CAP_KILL 5#define CAP_SETGID 6#define CAP_SETUID 7#define CAP_SETPCAP 8#define CAP_LINUX_IMMUTABLE 9#define CAP_NET_BIND_SERVICE 10#define CAP_NET_BROADCAST 11#define CAP_NET_ADMIN 12#define CAP_NET_RAW 13#define CAP_IPC_LOCK 14#define CAP_IPC_OWNER 15#define CAP_SYS_MODULE 16#define CAP_SYS_RAWIO 17#define CAP_SYS_CHROOT 18#define CAP_SYS_PTRACE 19#define CAP_SYS_PACCT 20#define CAP_SYS_ADMIN 21#define CAP_SYS_BOOT 22#define CAP_SYS_NICE 23#define CAP_SYS_RESOURCE 24#define CAP_SYS_TIME 25#define CAP_SYS_TTY_CONFIG 26#define CAP_MKNOD 27#define CAP_LEASE 28#define CAP_AUDIT_WRITE 29#define CAP_AUDIT_CONTROL 30#define CAP_SETFCAP 31#define CAP_MAC_OVERRIDE 32#define CAP_MAC_ADMIN 33#define CAP_LAST_CAP CAP_MAC_ADMIN#define CAP_TO_INDEX(x) ((x)

HowTo: Use OpenBSD In the Corporate Environment

OpenBSD has a reputation for high security and difficult operating systems for new user. But, some orginsations are using OpenBSD for everything including firewall, servers and desktop computers. This is quite impressive, from the article:

So our paid job is hacking on and deploying, maintaining, supporting... OpenBSD installations. We are also required to hack on things that can be merged back into OpenBSD itself and when it's not possible, then we change what we did so that it can be. Of course some developments are very specific to what we do and have no place in the project's CVS tree.

So, amongst other services, we set up and maintain several 100% OpenBSD-based infrastructures (going from the entry site firewall to the secretary's workstation) and this is what I'm going to talk about here.

As a side note, it is important to know that we are working exclusively for Fortune 500 companies (each operating in totally different and unrelated sectors).

Paravirtualization With Xen On CentOS 5.6 (x86_64)

nix operating systems like Linux and FreeBSD), so called "virtual machines" or domUs, under a host operating system (dom0). Using Xen you can separate your applications into different virtual machines that are totally independent from each other (e.g. a virtual machine for a mail server, a virtual machine for a high-traffic web site, another virtual machine that serves your customers' web sites, a virtual machine for DNS, etc.), but still use the same hardware. This saves money, and what is even more important, it's more secure. If the virtual machine of your DNS server gets hacked, it has no effect on your other virtual machines. Plus, you can move virtual machines from one Xen server to the next one.

I will use CentOS 5.6 (x86_64) for both the host OS (dom0) and the guest OS (domU).

This howto is meant as a practical guide; it does not cover the theoretical backgrounds. They are treated in a lot of other documents in the web.

This document comes without warranty of any kind! I want to say that this is not the only way of setting up such a system. There are many ways of achieving this goal but this is the way I take. I do not issue any guarantee that this will work for you!

 

1 Preliminary Note

This guide will explain how to set up image-based virtual machines and also LVM-based virtual machines.

Make sure that SELinux is disabled or permissive:

vi /etc/sysconfig/selinux

# This file controls the state of SELinux on the system.# SELINUX

Importing iptables Configurations Into Firewall Builder

Firewall Builder imports iptables configs in the format of iptables-save. Script iptables-save is part of the standard iptables install and should be present on all Linux distribution. Usually this script is installed in /sbin/.

When you run this script, it dumps the current iptables configuration to stdout. It reads iptables rules directly form the kernel rather than from some file, so what it dumps is what is really working right now. To import this into Firewall Builder, run the script to save the configuration to a file:

iptables-save > linux-1.conf

As you can see in the output below, the example linux-1.conf iptables configuration is very simple with only a few filter rules and one nat rule.

# Completed on Mon Apr 11 21:23:33 2011
# Generated by iptables-save v1.4.4 on Mon Apr 11 21:23:33 2011

The Perfect Desktop - Linux Mint 11 (Katya)

The system boots and starts a desktop that is run entirely in the RAM of your system (the Linux Mint installation DVD is also a Live-DVD) without changing anything on your hard disk. This has the advantage that you can test how Linux Mint works on your hardware before you finally install it.

This is how the Linux Mint desktop looks. Double-click the Install Linux Mint icon on the desktop to start the installation to the hard drive:
