The subject of third-party repositories is a touchy one for some people. For the maintainers of a distro, they feel that third-party repos cause compatibility problems and the packages are not subject to adequate Q&A. The third-party maintainers believe that they are maintaining either specially modified packages useful to their members or packages that the main distro cannot, for legal reasons, maintain and distribute. Both are correct.
If you need a package offered by a third-party repo, then by all means use it carefully. If not, don't even add the repos to your local repositories.
I recently compared the installation of
Mageia3 with Fedora 18 (both done in a VirtualBox virtual machine). When installed and fully configured to taste, you have essentially the same level of usability and ease of administration with a similar choice of desktop environments and current versions of applications running on a recent kernel using SysV-style init and RPM packaging. The meaningful differences are more easily illustrated
with some history, so this will not be the typical, dull, useless version-to-version comparison with a plethora of gratuitous screenshots and the inevitable inane jargon overload.
Fedora has been the community release
of Red Hat since RHEL became the primary distro for Red Hat proper.
It enjoys a more frequent release schedule than RHEL and is more focused on the
desktop. Think of it as the development version of the workstation
companion to the Enterprise version of Red Hat Linux taht is now in its 18th
Mageia would seem to be a relative
newcomer, only now in the beta of its third release, but its roots go
back to Red Hat 5.x with the release of Mandrake 5.2. Mandrake was essentially a re-spin
of Red Hat with better default configurations and an emphasis on the
KDE desktop (RedHat has long been GNOME-centric). A great idea plagued with poor corporate leadership and
even poorer corporate decision-making, Mandrake-come-Mandriva focused
its development in three areas: its package manager, its administration
tools and its volunteer community. Red Hat at the time still relied heavily on a text-based
installer, RPM and linuxconf, all of which required more than a
modicum of command-line mojo. RedHat were just beginning to develop admin
tools written in Python.
The Perl programming language was
adopted by Mandrake, both because the initial cadre of developers
were proficient in it and also as a way to differentiate themselves
from Red Hat. As well, they would not be simply "improving"
admin tools over which they did not have final control of the source code. It was a bold
gamble that both benefited them and undermined their success as few
other distros have adopted their tools.
Red Hat through the years only
begrudgingly accommodated their non-corporate user base and actively
undermined them at times. For example, Red Hat's early incarnation of
KDE was so heavily edited to make it less configurable and more
GNOME-like (and better suited for a corporate workstation) that it
elicited an uproar from KDE fans while documenting the Red Hat
developer's overwhelmingly "not invented here" mentality
(as evidenced by their scurrilous code comments). Fedora/Red Hat has always been
a GNOME-centric distro because the limited configuration options of
GNOME provide the best fit with their corporate workstation focus
and because many GNOME developers work for Red Hat. Red Hat, in the
name of "free software" also made their distro very
multimedia unfriendly by not only not providing easy access to
integrating less-than-free multimedia software, but by not compiling
in support for them if you wished to add them on your own. Again, it was a
more corporate-centric, IP attorney-friendly approach.
Many of the Red Hat/Fedora usability
advances in package management and desktop ease-of-use were fomented
by the loyal non-corporate user base. But this made the installation
and configuration of a usable home desktop system and easily updatable system a nightmare of tedium, spawning alternatives like Mandrake and KRUD, Kevin's
RedHat Uber Distribution, which provided a more friendly configuration
and a way to deal with updates that addressed "Dependency Hell"; it was
made obsolete by the eventual adoption of YUM as the RPM
wrapper and the growth of the Fedora user community.
The Mandrake/Mandriva installer was
steadily improving but idiotic corporate decisions were killing the distro:
non-sensical acquisitions and pursuit of computer-aided
training pillaged the start-up capital, but the user community was
strong. Meanwhile, the RPM wrapper application URPMI and the
user/administrator tools were coming along and Mandriva offered the
broadest out-of-the-box hardware compatibility of any distro.
Complicated configuration of things like X11, sound and printing were
almost fiddle-free and automatic. However, Mandriva's choice of
desktop and system graphics was uninspiring and almost child-like, certainly not
as cutting-edge and sexy as the up and coming Ubuntu.
Red Hat spun off the community version
of Red Hat as Fedora Core, then as Fedora. A growing user-focused
community sprang up to address it's usability shortcomings and has
flourished. Mandriva corporate neglected its user community and as it
approached bankruptcy for the second time, abandoned the desktop
version of Mandriva to community users and departing employees under
the auspices of Mageia.
The official Mageia base install
continues to demonstrate the ease-of-use "just works",
broad hardware support, sane default configurations and a
community-focused multimedia desktop. The official Fedora base
install continues to demonstrate the corporate-focused minimalist
approach Red Hat has traditionally taken to support their Enterprise
version and, as always, a strong community effort continues to take
up the slack and make it usable as a consumer desktop.
Desktop-focused Mageia has finally
stepped up its default look and feel to a polished, sophisticated and
modern level while corporate-focused Fedora looks flat and clunky in comparison (still, Mageia could use some more sex appeal). The bottom line is a very different out-of-the-box experience. Mageia's installation, default configuration and usability all best Fedora. Still, you can wind up with a very usable and essentially similar consumer desktop experience using either distro; Mageia just gets you there with less work and fuss. Overall, Mageia appears to have found it's raison d'être.
I have recently begun using Dropbox, being first introduced to it on my HTC Evo phone where it automatically syncs every picture I talk to my desktop PC.
There are some very cool things you can do with Dropbox and many sites around the Internet will clue you in (See the REFERENCES below). I'll concentrate on some things that are more Linux focused.
I'm a big fan of the Zim Desktop Wiki in that it helps me keep notes about specific configuration issues, tips, tricks and other useful info. But as designed, it is limited to a single desktop machine. I have several that I use, a few in remote locations. The solution? Zim keeps it's info in ~/Notes. Simply move the Notes directory into the ~/Dropbox directory and then symlink it back to ~. Now create the same symlink on every machine you use. Dropbox has now synced you Zim data to all your computers.
There are also a number of suggestions that you can do the same trick with ~/.mozilla. The only drawback I see is that you don't want to waste Dropbox space for the Cache files. Just keep the cache local by using about:config to change the value of browser.cache.disk.parent_directory to /tmp . Then you don't waste bandwidth or Dropbox storage on them.
You can only run one instance of Dropbox per user, but you may have multiple users on your system, each running their own personal instance with their own 2GB storage. Send each user an invitation so you get more free storage and let them set up their own dropbox accounts. Start the Dropbox daemon from rc.local like this:
su -user1 -c /home/user1/.dropbox-dist/dropboxd
su -user2 -c /home/user2/.dropbox-dist/dropboxd
While Windows users have problems trying to run Dropbox like this as a "service" such as need for Mac and windows users to stop the service to access the individual Dropbox management GUI, Linux has no such problems. When the user logs in, they will have a Dropbox icon in their tray and their files will be freshly synced.
While the tip to install portable Windows applications is nice, Linux users can keep shell scripts, custom config files, self-compiled software packages and so on for use anywhere.
XPaint is a desktop image editing application with a long history. It is currently maintained by Jean-Pierre Demailly, who will shortly be releasing version 220.127.116.11.
There is no RPM package available for Magia2, so I thought I would compile it from the source code, but I ran into some problems. The first was that naming conventions between the source code and what Mageia provides differ.
The XPaint INSTALL file says the following libraries (plus their development libraries) are necessary to compile XPaint.
Naming conventions are always annoyingly problematic. Mageia provides:
$ ./configure --prefix=/usr $ make $ sudo make install
Many thanks to Jean-Pierre Demailly for maintaining XPaint and for his generous assistance. If I can get motivated to learn a few new procedures, I might maintain an XPaint RPM for Mageia.
Jean-Pierre Demailly recently corresponded with this advice:
I forgot to mention (and that's probably hardly visible in the docs),
that it is advisable to compile libXaw3dxft with the options --prefix=/usr --enable-arrow-scrollbars The instructions above have been modified to reflect this.- ed.
The second option provides arrow scrollbars that have a look and feel similar
to modern toolkits, and XPaint behaves better with them enabled.
(I'll make that option the default in the next release, but the libXaw3d
variant doesn't and I did not change that yet ...)
UPDATE July, 2013
Because of the problems with libraries, I have not been successful compiling XPaint for Mageia3.
However, Mageia3 does provide gpaint which is based on XPaint and functions much like it. I now use that.
Part of the fun of Linux, for me at least, is the ability to fix things when they go wrong. And things generally go wrong when you don't follow the advice of conventional wisdom. Plus, my personal mantra is "fix it until it breaks".
One of those great pieces of common wisdom when discussing Mandriva is that you only upgrade within major versions, like from Mandriva 2010.1 to 2010.2, but when moving between major versions, like from Mandriva 2010 to 2011, you do a clean install.
If you have followed other convention wisdom, you have a separate physical partition for /home. With that configuration in place, you can do a clean install of the root filesystem and keep all you personal files and settings. But that can also pose problems since there is not always a clean upgrade path for the personal configuration files that live in the dotfile and hidden directories of your home directory. More on that at another time.
I wanted to upgrade (not update) from Mandriva 2010.2 to 2011.0 just to see what would happen. A look at the Notes for 2011.0 would indicate that such an option is possible with relative ease. Well, not really. Here's what you need to do.
After you have made certain that all you data is backed up and secure, the first step of the update is to update all the packages on your system.
# urpmi --auto-update --auto -v
Next, all the references to the 2010.2 repositories must be deleted.
# urpmi.removemedia -av
Then, 2011.0 repositories must be added. I also use the PLF repositories, so those need to be added those as well. You can do this automatically with EasyURPMI at PLF.
For the PLF repos (all on one line): # urpmi.addmedia --distrib --mirrorlist 'http://plf.zarb.org/mirrors/2011.0.$ARCH.list'
Note that the commands contain the variable $ARCH. I did that so you could copy the command and it would automatically detect your i586 or x86_64 system as appropriate.
Even after this has been done, some of the individual repos (the non-free ones) that are deliberately not enabled. To enable these, in your menu go to Tools : System Tools : Configure Your Computer. This launches the Mandriva Control Center. Then select Software Management : Configure media sources. Tick the boxes next to the repos Main Backports, Contrib Backports, Non-free, Non-free Updates, Non-free Backports, PLF Non-free and PLF Non-free Backports. Click on OK when you are all done and exit the Control Center.
If you want to avoid the lengthy trip through the menu system, execute drakrpm-edit-media in a terminal window.
If anyone is aware of a script that can have the same result, I would like to hear of it.
I have always found it better to do this kind of upgrade without the GUI running. So far, if you've been following along on your own system preparing for the upgrade, you've been able to cut and paste commands between your browser and a terminal window, but once the GUI disappears, that becomes impossible. Since the command to perform the actual update is a long one, let's create a shell script to execute it.
Using whatever text editor you prefer, create a file named 2011_upgrade.sh, make it executable with chmod +x and have it contain the following (all on one line):
#!/bin/shurpmi --auto --auto-update --replacefiles 2>&1 | tee 2011_upgrade.log# upgrade 2010.2 to 2011.0
Now, using Crtl-Alt-F2, open a virtual terminal and log in as root. Stop the dm service to shut down the window manager with:
# service dm stop
Now log back in as root, change to your home directory and run the 2011_upgrade.sh script.
The urpmi package manager now wants to install a lot of packages and urpmi is smart enough to know to install certain system-critical packages first. But urpmi cannot install python-numpy because if version conflicts. This causes the upgrade process to fail to install any python packages which will seriously munge your system and which prevents the installation of packages which depend n the newer version of python..
Don't panic and most importantly, don't reboot. Your system is running now and there is no guarantees that it will on a reboot.
The solution is simple. That is we should uninstall python-numpy manually and then re-install the most current version; this will allow urpmi to update python and unblock the installation of many more packages.
The problem we encounter is that the urpme command doesn't know how to uninstall python-numpy without also uninstalling every other package that depends on it. Normally that's a good behavior, but not for in this instance.
We'll need to use the rpm command to uninstall only the one package and then use it's smarter cousin urpmi to successfully update all of python.
# rpm -ev --nodeps python-numpy
# urpmi python-numpy
There may be similar notifications for other files. I was notified about libkexiv2 and x11-driver-input-evtouch. The same trick using rpm -ev --nodeps works with them as well.
With these problems fixed, run the 2011_update.sh script once more. Keep fixing and re-running until there are no more packages to update. Once that state is reached, it will be safe to reboot into Mandriva 2011.0. When 2011.1 is released, the same technique can be used, but there should be fewer problems.
One problem that did occur post-upgrade concerns networking. Mandriva 2011 implements a new network manager and your old network configuration files won't work with it. While you can use the network section of the Mandriva Control Center to fix this (I had to delete the connection and re-create it to make it work), it's easier to add NM_CONTROLLED=yes to the end of each ifcfg-* file in /etc/sysconfig/network-scripts. That's all that is necessary for the new Network Manager to control them.
Otherwise, everything works fine and I'm now running Mandriva 2011.0. That the upgrade worked as smoothly as it did is a testament to the work and expertise of the Mandriva team. If I come across other issues, I'll address them here.
Because I did not like many of the changes implemented in Mandriva 2011, I reverted all my desktops and servers to Mandriva 2010.2 and they will be upgraded to mageia2 when that is available.
There are two things that can help you to have some fun with Linux.
The first is VirtualBox. Since you are not using it for commercial purposes, you may download and install the full-featured version for your host operating system. If you are a MS Windows user curious about Linux, this is ideal for you. If you are a Linux user curious about different distros, this works as well.
After you install VirtualBox on your host operating system, you need to learn how to use it. the VirtualBox site has excellent documentation. My suggestion for configuration are give the virtual machine the maximum amnount of RAM and video memory that is practical and set the network choice to "bridged" rather than "NAT".
Next stop is to download the NetbootCD. This CD contaions enough of an OS to enable wired Ethernet connectivity and download and install several Linux distros via FTP.
Now you can create a virtual machine for each distro and experiment to your heart's content. This is much safer and easier to implement that dual- or multi-booting.
Remember that when using VirtualBox, you are only exposing the virtual hardware to Linux, not the real hardware of your machine, so learn how to identify your real hardware and learn how to use Google to determine the level of Linux support for it.
One last suggestion. When you do decide to install a Linux distro on your machine "for real", save yourself some headaches and obtain a second hard drive for your Linux install. If your hardware permits booting from an external USB drive and the distro you have chosen permits installing on a USB drive, you are home free. Otherwise, you'll need to install the second drive as a temporary replacement to get Linux installed. Then you can move it to an external USB enclosure .
If your BIOS does not permit booting from an external USB drive, you might find plpbt4win to be useful.It is a special bootloader that can boot an OS from an external USB drive. There are Linux and Windows versions.
If you've used Mandriva Linux, you'll feel right at home with Mageia. Mandriva has always had a reputation of working well for both the novice user and the power user. Installation is typically easy and hardware support is among the best of any distro. The user and administrative tools are comprehensive and easy to use. Of course, under the hood, it's all Linux and all configuration files are plain text files and all a competent administrator needs do is to choose a shell and a text editor.
Mandriva has also been known for excellent default fully-featured configurations of the KDE, GNOME, XFCE and LXDE desktop environments as well as a broad range of available applications. Mageia is no exception in thsi regard.
For the average user, the changes are mostly cosmetic. The Mageia art, colors and graphics are very well done (and contributed by the Mageia user community). But if it's just a pretty Mandriva, why is there a need for another Linux distro?
Mandriva began life as Mandrake Linux, based on Red Hat 5; Mandrake was essentially "Red Hat Done Better". It offered a well-configured KDE as the default desktop as well as its own administrative tools that provided more flexibility than those tools offered by Red Hat. The under-the-hood difference in these tools was that they were (and continue to be) written in perl language rather than the python language as used by Red Hat. Mandrake/Mandriva also spent considerable effort on its unique urpmi package management tool, essentially an intelligent, powerful console/gui wrapper around the RPM system of package management.
At some point, the business management of Mandrake/Mandriva lost its way, rallied, re-grouped and then lost its way again. The first time, they lost focus on Linux and the second time, they lost focus on their community. Mageia stepped in to fill the void in the community so that all the good things that were represented by the Mandriva distro would not be lost in the corporate buyout.
Which is why the software is so similar and the community is so different; you only need to fix what is broken.
Mageia offers the most recent verson of your favorite application software and all the major software you expect to be there is there. Mageia uses kernel 18.104.22.168 with additional patches for automatic process grouping andTransparent Huge Page support as well as support for AMD Fusion APUs and Intel Sandy Bridge and Panther Point chipsets.
Both 32-bit and 64-bit installation DVDs as well as a Live CD are available. Migration from existing Manriva 2010.2 installations is easily done. A large on-line software repository is available and provides a wide range of software of both free licensed and other licensed categories (the latter is not enabled by default, but is opt-in).
As with any initial release, you're likely to find a few minor bugs, but the Mageia community is there to help you. As a long-time user of Mandrake/Mandriva and co-author with Bill Ball of the Red Hat/Fedora Unleashed series, I believe you'll find Mageia a full-featured and easy-to-use Linux distro.
