As part of your editor's moral duty to be a torment to his children, he
requires them to use Linux whenever possible. They have come to realize
that Linux works well for almost anything required by their school, but
that it is not up to their requirements for fun. The lack of a World of
Warcraft client is a big problem, but the lack of solid Flash support seems
to be an even bigger one. The YouTube/MySpace lifestyle remains hard to
support on Linux; children are unimpressed by our high-quality Theora
One of the things your editor heard Lawrence Lessig say at Wizards of OS 4 was that
video is the communication medium of our time. The free software world
needs to better support this channel. In support of this argument,
consider that those of us interested in the next U.S. presidential election
(a mere year and a half away) may have to resort increasingly to anonymously-posted
videos to get our full share of attack advertisements. The best
mudslinging will be unavailable to those of us stuck in the text world.
While there are a number of video formats out there, what all of this
really comes down to is that we need decent support for Flash. For better
or for worse, Flash dominates in a number of areas, including
network video and a number of interactive site features. It's not just for
really obnoxious advertisements anymore. We do not have decent support for
Flash now; that proprietary plugin just does not cut it in the free
The good news is that we're getting closer to the level of support we
need. In particular, Benjamin Otte has recently announced
that the swfdec Flash
player is now able to work with video from YouTube. In general, swfdec has
some ground to cover yet; to answer the question of whether swfdec can
replace proprietary Flash Benjamin writes:
That really depends on your definition of close. For the definition
"implements all of Flash's features" it'll probably not hit 5%. For
the definition of "plays all the Flash files on the Web" I think
it's 80/20 right now. Swfdec plays 80% of the ads and 20% of the
What's important here is that swfdec has hit a point where it will start to
be truly useful; that, in turn, may help to attract more developers to the
project. A program which almost works is often more attractive to hack on
than something which is just a promise for the future.
Swfdec is not the only Flash-related project out there; Gnash is also working toward
a solution to this problem. Gnash would also appear to be at a similar
point in development; the project is not quite ready to proclaim YouTube
support, but, according to Gnash hacker Rob
Savoye, that's a result of different objectives:
I don't want to sound like I'm insulting swfdec, I think it's good
there are multiple open source flash players. But swfdec is tweaked
to handle primarily YouTube, Gnash handles many more Flash movies
correctly. It's a difference in focus.
Given that what we need is one truly good Flash player, one might well
wonder what the point of two competing projects is. That is the same
question people asked about desktops in the past; at this point it seems
clear (to your editor, at least) that the competition between GNOME and KDE
has helped to increase the pace of free desktop development and to explore
different approaches to the graphical Linux experience. The important
thing is to focus on
the development and stay away from silly flame wars. To that end, Rob's
message contains some good news:
We all spend alot of time talking about Flash
internals. [Benjamin's] very happy. We're happy too, because of the
discussions of how swfdec and Gnash are implemented, we're learning
things from each other's experiences.
If the projects can continue to cooperate and learn from each other, Linux
should have a high-quality Flash implementation in short order. If some of
the more desktop-oriented distributions were to realize that supporting
these projects is very much in their own interest, it could happen even
sooner. There are few limits to what a free software project can do once
it gets rolling.
A good Flash player is just the beginning, however. If we want free
software to have a significant role in the creation of all this content, we
need good authoring tools - and those are rather further behind. Another
thing Lawrence Lessig urged was the creation of a free software culture for
Flash developers, almost all of whom are, for all practical purposes,
shipping binaries at this point. Some good free Flash tools, along with
increased support for sharing source, could transform the Flash development
world - for video and more. We could help to bring freedom to an important
communication medium; that would be even better than creating the ability
to watch silly videos with free software tools.

Your editor recently decided to pick up a Nokia N800
tablet device. This
acquisition wasn't just another case of yielding to the lure of a new
gadget - your editor would never
do that. Instead, the hope was
that the N800 would be useful as a way of getting onto the net and dealing
with simple situations without having to haul the laptop everywhere.
Besides, such a device is always good for an article or two, at a cost that
isn't that much above buying an article from an outside author.
Besides, it's a cool new gadget.
The N800 is, naturally, a Linux-powered device. It has an 800x480 screen,
two speakers, and a pop-out camera. There's a headphone jack, a USB port,
and two SD memory slots. The device can communicate wirelessly via 802.11
or Bluetooth. Also provided is a stylus which is used for most interaction
with the device; there is a built-in storage slot for the stylus which
should help to prevent loss, but it's still nice that Nokia thought to
provide a spare as well.
On the connectivity side, the N800 developers have done some nice work. On
the first boot, the tablet offers to pair with a Bluetooth-capable
phone and set up a GPRS connection automatically. Anybody who has been
through the process of setting up a Bluetooth/GPRS link on a Linux system
knows that there can be a certain amount of pain involved - and that's
before trying to get any real work done over such a painfully slow
connection. Having GPRS Just Work is a nice bonus. The tablet also
handles WiFi connections easily.
After that, however, a new N800 user might well feel at a bit of a loss. The
startup screen includes a Google search bar (the usage of which is entirely
straightforward), an RSS reader window with no subscribed feeds, a contact
manager window (with no contacts, obviously), and a "Discover Tableteer"
window which, when "tapped," opens a web browser on a remarkably static and
unhelpful Nokia page. Digging through the menus yields a simple email
client. Anybody expecting something that feels like a normal
Linux system will be disappointed; there's not a whole lot else there.
That can be changed, of course; we'll get to application installation
The tablet comes packaged with a user's manual, in PDF format, in a large
number of languages. The user will not encounter this manual until he or
she happens to fire up the file manager and look in the right place,
however. The "Discover Tableteer" window does not do much to help a
beginning user find this useful document.
Text entry is done through a keyboard which appears at the bottom of the
screen; individual letters are approximately 2mm square. In practice, the
letters are not hard to hit, and, with a bit of practice, one gets good at
entering text quickly. Learning the simple gestures to minimize trips to the shift
keys helps a lot. There is another mode where the keyboard expands to fill
most of the screen; in this mode, the stylus can be put aside and text can
be typed directly with the fingers. It works, and can be nice for extended
text input, but your fat-fingered editor had a hard time using it as a real
QWERTY keyboard. Finally, the tablet does support handwriting recognition,
but your editor has not really had a chance to play with that mode yet.
The web browser is the proprietary Opera application. It works reasonably
well for the most part, making good use of the limited display space. Your
editor has found it to be not entirely stable; it occasionally hangs and
must be restarted. Dragging Google maps
around does not work. Pages generally render well, though; the browser is
good enough for the sort of work one would want to do on a small tablet
Your editor tried the Minimo
browser as well. It does not seem to render pages as nicely as Opera,
based on some quick tests. It is also far less stable; your editor managed
to crash it almost immediately. Still, Minimo will stay on the system in
the hope that it gets better; your editor would much prefer to run free
software on this system.
There is an application manager which can be used to install more software
onto the tablet. The bad news is that it has little to offer out of the
box. The good news is that one can go to maemo.org to look for a rather wider variety
of software goodies for the device. The bad news is that the majority of
those applications, as of this writing, say "missing install" and cannot
actually be installed onto a tablet. The good news is that there's still
quite a few useful tools available. In short order, your editor was able
to equip his tablet with essential utilities like xterm and an ssh client.
The really bad news showed up with some of the other interesting
packages, such as vim and gnumeric. The application manager will happily
download the packages before popping up a window which says:
install: some application packages required for the installation are
Such a message would perhaps have been acceptable ten years ago on some
distributions. One would not expect to see it on a Debian-based system in
2007. There is no excuse for an "application manager" which is unable to
handle dependencies anymore.
The N800 includes a (proprietary) Flash player and a media player as well.
As many others have noted, the tablet comes well equipped to handle
patent-encumbered formats like MP3 but it cannot play an Ogg file. One can
make an argument for minimizing the size of the base system on a
resource-limited tablet, but there's no easy way to fill in that gap
afterward either. It would appear that installing an Ogg player, at this
point in time, would involve downloading the development kit and building
the application from source.
In general, the N800 feels a little like an unfinished product. Nokia has
created a nice piece of hardware, based (mostly) on free software, and
appears to be hoping that the development community will help turn it into
a fully capable device. The company's practice of selling tablets to
developers at a sharply-reduced price is clearly intended to help make this
happen. One can only hope that Nokia succeeds here; the company has done
what we really need it to do: made a open, Linux-based device. We certainly have
the ability to make it do interesting things from here.

If I had to choose the single moment that defines when the Free
Software movement became self-aware, it would be the 1983 publication
of the GNU manifesto by
Richard Stallman. Despite its age it is
amazingly up to date. Free Software has come a long way since that
time; creating an alternative by inspiring people to put together the
GNU Project piece by piece on a proprietary platform.
Only with the publication of the Linux kernel were people able to see
pure Free Software operating systems running on their computers in the
90s. But they were still booting off a proprietary BIOS, and we also
saw an increasing tendency to put hardware functionality into
proprietary firmware. Only recently have projects such as LinuxBIOS
managed to bring more freedom to the BIOS, although notebooks
still are problematic. The issue of proprietary firmware is still
being worked on, including by
Compared to the situation in the personal computer area, embedded
devices are still several years behind, but there are people who are
working hard to catch up. I recently had the pleasure to learn a
little more about this exciting field.
One device that a lot of people have in their homes or offices are
routers to connect to the internet. Until not so long ago, these used
to be entirely proprietary. That is no longer true. Not only do
several vendors provide routers with more or less free firmware based
on the Linux kernel, but the OpenWRT
project and its younger
offspring the FreeWRT project have
also made some amazing advances
in this area.
However even though FreeWRT has a web
interface to build custom
firmware online, both are still catching up with the freedom,
ubiquity and sophistication of modern GNU/Linux desktop distributions.
There are still problems with hardware compatibility and drivers, as
both distributions are still confined to a certain chipset, and locked
into the 2.4 Linux kernel series because of proprietary drivers for
the wireless card built by Broadcom, a manufacturer that has proven
itself to be very uncooperative towards the Free Software community.
Getting rid of these restrictions to freedom is a collaborative effort
with many different players, including FSFE's Freedom Task Force,
which helped the OpenWRT team to avoid making mistakes in the reverse
engineering of the Broadcom wireless driver, such that the result will
then be fully usable by all Free Software.
The situation with mobile phones and PDAs is even worse than that of
routers. Until very recently it was close to impossible to find mobile
phones that were running Free Software and gave the user control over
what they were doing.
One of the first companies that tried to answer requests for Free
Software mobile phones was Trolltech with their Qtopia
Maybe because this was the first time this was tried, and maybe
because they didn't consult enough community voices before launching
the phone, they made some mistakes. One of them was the overly
restrictive EULA terms, which Trolltech quickly corrected after
with the problem.
This was not the only problem. The Greenphone's package management is still
proprietary, although that problem can be mitigated by using the ipkg
package manager instead. Ultimately it seems that everything but
the communication stack can be replaced by Free Software in this
way. So the Greenphone was a step in the right direction, but it is
not yet good enough.
The interest it raised probably also helped bringing about the
OpenMoko phone, which will ship very
soon and which is taking
another big step toward freedom. Like the Greenphone, the GSM stack
remains proprietary, though. Reasons for this appear to be a thicket
of cross-licensed patents and regulatory concerns about frequency
usage and transmission strength.
Many politicians are concerned that tinkering with these could impair
the ability of other people to communicate, including the ability to
access emergency services. Their argument is that the potential damage
done by tinkering is greater than the damage of not having the freedom
to change the code. This is a reincarnation of the old "your freedom
to swing your fist ends at my nose" argument, and it is not easily
discarded. We need to convince society with good answers to this and
because of that, the GSM stack is likely to remain a difficult area
for some time.
Depending on when you start to count, it took our community at least
10 years to address the issue of the proprietary BIOS on our PCs, but
we did not let this stop us from improving our GNU/Linux Desktops. In
the same way I believe we should work to create maximum freedom on
Other possible candidates have been launched by Nokia, namely the 770
and N800 internet tablets. Both
devices are running a Linux
kernel with a very small GNU/Busybox system using Debian package
Because they do not need the GSM stack, these devices might be made
entirely free, though unfortunately they are not being shipped that
way. They come with the proprietary Opera browser and a Flash player,
which are easily uninstalled and can be replaced by a Mozilla port
maybe Gnash can be
compiled for them as well.
But there is more work waiting to be done: In a sad kind of irony
Nokia seems to have chosen the Gtk+ library over Qt because that would
allow them to keep part of their helper library for the embedded small
screen proprietary. There are also other parts that are still kept
proprietary, like the boot loader and battery charging
application. They also seem to share the proprietary firmware problem
with the personal computer platform. Even the flashing utility is
proprietary software at the current point in time.
This has made some people very
sceptical. It may even turn out
that we will not be able to free these specific devices entirely
without Nokia's help on the hardware interfaces, which may never
come. But working to free them will inevitably end up providing more
freedom, although maybe not on these specific devices. Experience
gained can be used in many ways, and Free Software written can be
transferred to other platforms.
Like the Greenphone, these Nokia devices provide a substantial step
towards freedom, but are not yet good enough. So they have to be seen
as an intermediate step towards freedom in the embedded world. Both
Trolltech and Nokia deserve praise for making a step into the right
direction, as well as constructive criticism on the remaining
proprietary parts, which should also be set free.
There are projects that have already gotten very far in this effort
for other devices, like the Familiar Project for the iPAQ
which, I was told, is now running fully Free Software except for the
wireless driver. And there are other devices that seem capable of
running Familiar, like the Siemens Simpad, which also spawned its own
community project to set it free. So maybe a FreeMaemo.org
project is what we need for the Nokia internet tablets.
An essential element in truly achieving freedom in the embedded world
will be to further strengthen the Free Software community in this area
and enable more Free Software developers to tinker with these devices.
One person who has done extraordinary work in this area is Harald
Welte. His signature is also visible all over the OpenMoko project and the
way it actively reaches out to build a strong developer community. We need
more people like him and the other OpenMoko developers, and I hope you will
take a look at their
call for GPL'ed wireless drivers and application developers.
We also need to get more of the devices into the hands of capable
developers. This is what Armijn Hemel of gpl-violations.org did
during FOSDEM 2007 when he gave a bunch of routers to the OpenWRT
project so they would have more devices to work with and set free.
Ultimately freedom is not static. It is a process that involves a lot
of work. It is also a differential question: There are steps towards
more freedom, which are good, and steps towards less freedom, which
cause problems -- if not immediately, then in the future. The choices
of which direction to take were recently described by FSFLA as "The
As a community, we have set the personal computer free to a very large
extent. We are not yet as far with embedded devices, but there are
first signs of the Free Software community growing into this area.
With the possible exception of the GSM stack, I believe we have good
reason to expect 100% Free Software devices in the near future by
starting from the most free, although imperfect, options available and
setting them free entirely.
Through this effort we'll not only see the Free Software community
flourish in this area and we are also likely to see more hardware
vendors willing to supply the community and people who value their
freedom with such devices.
Eventually it will be possible to enter the store and buy such a
device running only Free Software out of the box, which is what I
really want. And with projects such as the GPE Palmtop Environment
we will be able to use the same software environment on different
hardware devices; something that is common on personal computers, and
a great advantage.
Working for this goal can serve to strengthen Free Software on the
desktop, because integration of the mobile devices with desktop
computers is an important issue. With Free Software it could be
possible to use the same software on both, possibly in different
versions and from different vendors. The result would be seamless
integration that proprietary software might not be able to achieve
across vendor boundaries.
It seems only a question of time until someone picks up on this and
offers the combination of freedom and convenience to people. In the
end, by walking forward on the road to embedded freedom, we might end
up strengthening Free Software overall.
