If you've used Mandriva Linux, you'll feel right at home with Mageia. Mageia has quickly established 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.
If you've used Red Hat or Fedora, the differences with Mageia are examined here.
Just like Mandriva, Mageia is known for excellent default fully-featured configurations of the KDE4, GNOME2, LXDE and other desktop environments as well as a broad range of available applications.
For the average user, the changes in Mageia4 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 or prettier Magia3, why is there a need for a newer Mageia distro?
These changes are mostly "under the hood", but are done to keep pace with improvements in technology and compatibility with standards and interoperability.
Most tools have been ported to Gtk+-3which will allow the use of the Broadway technology. For improved security, all admin tools have been ported from to polkit when needing root privileges. Mageia 4 still comes with GRUB as a default but also provides GRUB2 for forward compatibility. For GNOME2 fans, the MATE desktop is available; it is a updated version of GNOME2. All software packages are the most recent stable versions (a few are stable beta releases).
Mageia began life as Mandriva. Mandriva began life as Mandrake Linux, based on Red Hat 5.2; 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.
Mageia4 offers the most recent version of your favorite application software and all the major software you expect to be there is there.
Both 32-bit and 64-bit installation DVDs as well as a Live CD are available. Migration from existing Mageia3 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). Third-party Repositories are also available.
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.
I'm always looking for ways to speed up my computer, especially when it comes to the boot process and loading applications. A good overall discussion or improving system performance is at https://wiki.archlinux.org/index.php/Maximizing_Performance, just remember that it focuses on the ArchLinux distro, not the Mandriva distro I use.
A useful utility is readahead. According to its manpage, readahead populates the page cache with data from a file so that subsequent reads from that file will not block on disk I/O. On my Mandriva 2101.2 system, the default installation of readahead places a default file at /var/lib/readahead/default.early. To create custom files based on your system, you should reboot the system and pause the GRUB menu and add the following to the command line.
This will examine your system as it boots and create a list of what files are to be loaded in the order that they are loaded.
The configuration file is found at /etc/readahead.conf and this is where you can turn on debugging if you're experiencing problems and can add excluded directories.
Next is the prelink utility. According to the man page, prelink is a program that modifies ELF shared libraries and ELF dynamically linked binaries in such a way that the time needed for the dynamic linker to perform relocations at startup significantly decreases. Due to fewer relocations, the run-time memory consumption decreases as well (especially the number of un-sharable pages).
The file /etc/prelink.conf contains a list of files and directories that prelink uses to determine where it should look and what files to avoid. Prepending -l (or -h if on a networked filesystem) to a path makes prelink search that directory for ELF binaries or shared libraries. You can prepend -b to blacklist a directory or a file to avoid which will speed up the search or deliberately avoid prelinking certain binaries.
Mandriva provides a directory to keep your customizations separate at /etc/prelink.conf.d/; just create a file there ending in .conf and your customizations will be included. The general invocation is
Back in the early days of Linux, the changes to the OS were so dramatic that even when updating withing the same distro, in-place point release updates were problematic enough and it was always recommended that a major version release be done from scratch. There were just too many major changes to the underlying subsystems and package naming conventions. Doing an in-place update was just asking for trouble.
Modern distros have matured quite a bit although there are occasionally some major subsystem changes being made. Yet it's never been easier to do an in-pace major version upgrade.
I just did the upgrade on several Mageia3 systems and the results were consistent and satisfactory, not to mention simple.
Always backup critical information. Have a Mageia3 recovery disc on hand.
Reboot. You'll be using a new kernel, new glibc and so on.
$ sudo shutdown -r now
Run the package update command again. It should return with no packages needing updating.
Done. But . . . .
Do Some Checking.
$ cat /etc/redhat-release
$ cat /etc/issue
Those commands should return the information that you are running Mageia4. I did have an issue on one machine and $ sudo urpmi mageia-release-commonfixed it. You can also edit these files to change the version number.
The subject of third-party repositories for Mageia 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. 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 screen-shots 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: nonsensical 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.
No matter which you choose, 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 126.96.36.199.
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.
