20/11/07 Harnessing the power of the SUN : Project Looking Glass
Graphical user interfaces have been around for a while now. In the last
thirty years the available resolutions to the developers has gotten
greater and this inevitably has spawned prettier and cleaner themes,
however there is very little in the way of innovation Whilst looking
into GUIs, the same tried and tested methods are there. They focus on
chiefly on static, menu driven systems and desktops that vary in
implementations and design, but rarely innovate.
The Early Years, between 1980 and 1990s was the .com boom for GUI
interfaces. For us now its a fascinating time because its strange to
think of Microsoft has being anything other than a massive monopolistic
corporation that is shoving Vista down our throats. Sure we compute in a
world safe in the knowledge that the 'cool' guys use Macs and that Linux
is that sexy broad thats always just out of reach of the ordinary guy.
But it was not always like this, in the very early years of command line
interfaces and dodgy shells the GUI really started in earnest with the
Apple Lisa
Project. It featured drop down menus and desktop icon spaces and was
definitely ahead of its time.
From 1984- 1988 the Operating system market was very healthy, with no
fewer than 5 different Operating Systems being released and updated. In
the few years since then, several contenders have battled it out trying
to assert dominance over the Operating System scene. Some emerged
'victorious' (e.g. Apple, Linux, Microsoft) and others faded into
distant memory (e.g. Geoworks, Amiga, IBM's OS/2, QNX, BeOS, Acorn, NeXT
and others.) It is not until the early 1990s that things started to get
interesting, Windows 3.0/3.1 and NT 3.1 were all released within a few
years of each other adding a much need update to the old DOS mode
graphics.
Throughout all of this, the basic way in which a workspace environment
is structured had not changed, no new interface ideas come forth during
this era. The operating systems were very different on a code and design
level, but the basic menu / desktop point and click interface was well
and truly established by this stage. Recently hardware 3D rendering has
taken center stage and is most commonly seen with Vista's Aero Glass
effects. Linux is the platform on which the greatest innovation is
taking place and this of course is as a result of the openness of the
platform - the ability to code / implement anything. Whilst the main two
desktop managers (Gnome
and KDE)
are most widely known and recognized there are many fringe desktop
mangers from minimalist (e.g. XFCE,
flux/busybox)
to the specialist (e.g. enlightenment). Whilst providing a great degree
of flexibility and variety, they do not really innovate. An exciting
project on Linux, originally started by Novel, forked in 2003 and in
March remerged back into Compiz Fusion. This was the Linux answer to 3D
rendering and whilst the variety and flexibility of Compiz / Beryl (now Compiz
Fusion) are astounding,
they still offer very little in the way of innovation, just a LOT of eye
candy.
And now, finally, I get to the point of this article - desktop managers
and the future (check back in five years for a laugh) of desktop
interaction. There are three projects which potentially offer new ways
to interact with the desktop are Bumptop's physics
enabled desktop, Microsoft's Photosynth
and Sun's Project
Looking Glass.
Physics - on a desktop?!? Madness?
Bumptop is
primarily a desktop icon manager, but its main selling point is that
every icon (or groups of icons) can be moved / rotated / thrown around
the desktop like a chip on a poker table. An obsessively neat person? No
problem, stack your icons by file size, document type or by content.
Having a stressful day a the office? Throw your desktop clutter around
until you feel better!
The flexibility of this manager is astounding, but whether it will need
a new level of human-machine interaction before it takes off remains to
be seen. If you have not yet seen their demo on youtube you
definitely
should.
Photosynth - Surprisingly innovative
Whilst not normally one to be particularly impressed by Microsoft and
their 'technology', I am fascinated by Photosynth. The ability to create
3D objects from a series of photos is definitely an interesting concept,
but its the way Photosynth presents the documents that could
revolutionise the way we store and view documents in the future. To me,
this is what I had in mind when Microsoft were talking about a
journalised database filesystem back in the days of longhorn. Whilst
this is the main focus of the technology, I was simply stunned at the
way in which this project groups media. Regardless the size / dimension
or media type, a 3D rendered wall is created of all your documents at
the same time. Opening one is as simple as zooming into the image or pdf
document. Of particular note was the ability to render books in their
entirety and zoom from the outset into a single chapter.
The presentation is ten minutes long and there is no excuse for not watching
it! :)
Project Looking Glass - Beware on a Sun-ny day.
I came across this project today and was quite taken with it. Initially
it looks like a series of snazzy extension to Compiz, however when you
dig a bit deeper you find that there are a handful of rather cool
features. Rather than windows minimising to a taskbar, they rotate and
stick in a 3D fashion to the sides of the screen.
This gives you not only a stack of windows occupying the minimum of
desktop real estate, but a preview of each window at the same time
making it the ultimate cross between Alt-Tab and the 'live' preview that
hovering over the window gives you in Windows Vista and Compiz Fusion.
Whilst the taskbar is used as a window dock, rather than being docked as
tabs, widgets
with window previews are used to further add to the experience.
Also demonstrated is a media
player that allows track / album selection through a slew of
rotating CDs with cover art. This looks a really clean way of quickly
and easily selecting your music rather than searching through a long
list.
Another interesting feature is wallpaper
that is different on each desktop space (but part of the same
overall picture). In the youtube
video, the default deskspace is in the center, when you look at the
left or right screens, you see the left or right part of the panoramic
wallpaper, a very neat feature.

I previously
wrote a brief article about gOS - the new cheap FOSS pc that brings
Google Apps combined with Linux to the masses. Interestingly today I
came across the 'dev
kit' version, for $60 you can buy the motherboard and processor out
of this PC which normally retails for > $200. This is a hackers dream as
the main criticism with the initial gOS was the fact that it came in a
shockingly large ugly case for the size of the internal components. I
was sorely tempted to buy it in order to harvest the internals and build
it into a slim client. This dev kit would make it a lot easier (and
cheaper) to do however its only available in the US at the moment.
In a refreshingly philanthropic move (especially historically when
intellectual property has been involved) Will Wright has donated the
original SimCity for the One Laptop Per Child project in the hope that
it will inspire a generation of OOTB (out of the box) thinkers. This
idea was born from the 'SimCity.edu'
project by Don Hopkins, essentially making SimCity into a multiplayer
game to help teach Civil and Environmental Engineering running on
Linux/X11.
Also, while you are browsing, an old friend of mine told me about 'The
Nites', an unsigned band that have some great music on their
Myspace. I highly recommend listening!
... and to my regular visitors I promise, the next post will be original
content rather than hotlinking. I humbly submit myself for your
forgiveness.
Woohoo! The eagerly awaited Daedalus R13 is here after a four month
break between releases! Here is what StrmnNrmn
had to say today:
...The most significant new feature is savestate support. You can now
save your progress at any point, via the Pause Menu (accessed through
hitting the Select button). Savestates are written out to the memory
stick, and consume around a megabyte per slot. You can load up a
savestate at any time from the Pause Menu, or via the front end (hit the
right shoulder button to swap from the rom list to the savestate list.)
Whilst StrmnNrmn has not been working on increasing compatibility, he
has been working on optimising the dynarec stack which should allow for
a 10-20% fps increase in exisiting games. I have downloaded it and will
post feedback when I have had a chance to get to grips with this new
release.
RAM, all computers need it, and there are more types of it than you can
shake a stick at (excuse the pun), and people often take it for granted,
however faults with RAM are one of the quickest ways to screw up your
computer, more so than almost any other component except perhaps a dodgy
power supply (QTech anyone?). I have personally busted entire Operating
System installs with bad ram overclocks- times like that you better pray
you weren't stupid enough to leave your valuable documents ect on the
same partition as Windows.
So RAM stability is the cornerstone of a reliable computer, and whether
or not you overclock your components, knowing that you computer is
stable is peace of mind that you can't put a price on, but how do you go
about testing your system to see if all is running well, or if you have
hidden faults waiting to surface and destroy your valuable data?
In fact with a little know-how you can do it totally free if you have a
spare hour or two (mostly unattended), and this brings us to the topic
of this brief(ish) article....... MemTest and Memtest86+,
the only RAM testing software worth talking about.
MemTest
is a tiny windows exe that allows you to input the amount of memory that
you wish to test, and then chuggs away happily testing it, telling you
its progress by a % of the RAM you have assigned it, while you do other
things (though beware it will use up a substantial amount of CPU power
as well), leave if running for a hour or two, and if it has any errors
then your RAM is unstable. There are fundamental limits on the
reliability of this though, as the amount of RAM being tested by a
single occurrence of the program is 1184MB (this can be circumvented by
running two versions at once however), and also as the program obviously
cannot access RAM being used by the Operating System, or by the user,
you may miss "Bad" sectors of your RAM by the fact that they are being
used!
Memtest86+
is the bigger brother of MemTest, and treats the testing with a rather
more serious approach. Rather than a Windows program, you have a
bootable CD, or a USB/Floppy EXE for use from DOS. This more rigorous
approach allows you to test the entire RAM (bar the few kb in takes up),
rather than the small amount you assign MemTest to use, as there is no
Operating System or other programs running. Memtest86+ also has a series
of different "Tests" that it runs, of differing complexities, in each
"Pass". To make life even easier, many Linux CD's carry a copy of
Memtest86+ accessible from the boot menu, so there really is no reason
why you shouldn't have a copy close to hand. If you don't have a linux
live/install CD handy then you can obtain via a small download a version
to run from a floppy or USB key from the official
site.
RAM that produces ANY errors on Memtest86+ is faulty and should be
removed from the system ASAP, and preferably returned for replacement.
Leaving it in the system can cause problems varying from occasional
program freezes and crashes, through to corruption of files and total
Operating Systems. Most RAM has an extensive if not lifetime warranty,
so there is no reason to run the risk of running faulty RAM.
I personally use both the programs, MemTest for quick testing while I
have other things to do, often when i am trying to initially test the
stability of an overclock, and then Memtest86+ when i am either trying
to analyse for long term stability, or trying to identify RAM with an
inherent fault. The pictures you see above come from recent tests of my
own system, analysing my 4 RAM sticks for errors, 2 of which you can see
have been diagnosed as faulty and need replacing and has since been
removed from my system.
So whether you are an overclocker looking to squeze that extra bit out
of your system without compromising on stability, or just someone that
wants a computer they can depend on, MemTest and Memtest86+ are great
tools that will allow you to rely on your computer with certainty.
02/11/07 Enlightenment DR17: Installation on Ubuntu 7.04
Newsbrokethis
week of a new sub $200 system being sold in American stores running
a 'gOS'
distribution of Linux. As it turns out the 'g' is indeed for our
overlords Google as the system comes with several Google Apps installed
as per default. In the obligatory attached screenshots I noticed a
slightly unusual desktop environment running and decided to do some
digging. It turns out that the window manager used is the minimalist
Enlightenment with a number of tweaks and customisations. gOS is
available as a LiveCD which I have now downloaded but not had a chance
to try. Seeing some quite impressive screenshots of Enlightenment DR17
in action I decided to take the plunge and try to install it onto my
Ubuntu 7.04 laptop. This took about an hour because it has to compile
and a lot of the material you find is out of date.
The last official built (E16) was released in 2000/2001 and as a result
its horribly out of date. The most recent unstable release is DR17.
Unfortunately with this release, it has to be built from CVS although
there is a script written by Morlenxus which greatly simplifies the
process. Annoyingly, since the last unofficial release was a good few
months ago, the default dependencies have either changed, been
superseded or have broken. As a result it might take a few attempts
before the script completes. I opted for the minimal installation +
extra modules.
The first thing I needed to do was add the appropriate sources to my
sources.lst. This can be gone either from the GUI or via:
sudo [insert your favorite text editor here e.g. gedit]
/etc/apt/sources.list
and add these lines...
deb http://edevelop.org/pkg-e/ubuntu edgy e17
deb-src http://edevelop.org/pkg-e/ubuntu edgy e17
Save and close. Next you need to download the gpg key for this
repository to check the digital signatures of the code downloaded.
wget http://lut1n.ifrance.com/repo_key.asc
sudo apt-key add repo_key.asc
You can now delete this armored key file. Next you will have to update
your lists.
sudo apt-get update
SIDE NOTE: According to ubuntugeek, all that is now required is
the command 'sudo apt-get install e17' however this is not how I did it
so I can not attest to this working.
Next I downloaded and installed some required dependancies to make sure
they were all present on my system.
Now I downloaded the rather good script by Morlenxus using the following
command. Make sure you are in your home directory for this. (If you are
not sure use the command pwd)
According to the official instructions, the next command entered should
be './easy_e17.sh -i' this would by default install E17 with all
the modules and dependencies This did not work for me for the reasons
described above so instead I used the following command.
Save and exit. With the skip script above, Entrance, the default login
manager for E17 has been left out as it can sometimes cause problems
according to several threads. As such your existing login manager will
be used. A guide how to install Entrance with E17 can be found here
and basically involves removing entrance from the --skip.
We now need to add an entry for Enlightenment so that it is can be
loaded after login.
sudo [insert your favorite text editor here e.g. gedit]
/usr/share/xsessions/enlightenment.desktop
Please note the _start in bold. This is important and not on any of the
forums link to from this article. If you do not add this then
Enlightenment will not start properly. It crashed on loading and
recovering via F1 didnt fix the problem so appending this will save you
some headaches.
That will give you a fairly minimal E17 to customise. You will however
want to change from the default theme fairly quickly and Get-E.org
is a great source for themes. As a side note, if you want to update E17,
use the following command :
sudo ./easy_e17.sh -u
Enlightenment also supports animated backgrounds, however I have not
tested this feature and all the example videos I have seen show it to be
horribly stuttery.
For more information or support I would encourage you to visit the
following places : old
& updated
ubuntu installation guide, Enlightenment
page.
As a whole, I rather like E17 but I have not had enough time to really
play with it. When I have I will post some more on the subject.
I have known about the openbios
/ linuxbios project for a little while now, but today I discovered a
video demonstrating an early build running on a standard 2Mb flash
EEPROM. Not only does it completely replace the standard Award BIOS but
it boots to a graphical (if lightweight) X11 server in just a few
seconds. Although this project is still fairly new (shown by limited
compatibility) the concept of having a unified, free bios that
allows fast prebooting into a graphical environment is appealing. I
believe Macs do something similar, they boot into a very stripped down
GUI giving graphical boot options. This idea is not new and ASUS
demonstrated a couple of weeks back a motherboard that has an embedded
linux distribution ready to boot before windows. The technology is
called Splashtop and
allows access to email, skype and the web from a stripped down linux
environment.
More and more I am seeing a trend towards 'at-an-arms-length' computing
and I have mixed feelings about it. Whilst linuxbios would allow better
/ more efficient booting into a Linux (or other OS) distribution, having
a stripped down environment where you could then VNC or telnet into
another more powerful system is an interesting idea with lots of
potential applications. Imagine a media center PC that was fast (as in
instant) to boot and silent due to all the processing being done on
another machine on the network, it would be an ideal mediacenter
environment. Similarly there is a low murmuring that has been increasing
in volume for the last few years concerning a complete shake up of the
traditional computing environment. It essentially started with web '2.0'
i.e. applications as a service. The whole idea of being able to log into
a personalised environment in a web browser is an appealing one, be it a
web operating system like eyeOS or just
a social networking environment like Facebook. Not only can you have
access to your personal space/files/environment remotely, but instead of
buying a powerful machine and maintaining its software and hardware,
buying a thin client and computing entirely online. Many people simply
do not have the technical expertise or the time to properly maintain
their home computers. Simple tasks such as regular defragmentations or
temporary file cleanup and data archiving often are not done regularly.
Many computers I see do not even have basic security programs running. A
secure thin client running on a whitelist
basis would not need such constant attention and any security would
be handled remotely by the application provider. Potentially providers
could offer really cheap, low power machines with a monthly payment,
which would serve as a lease for an online operating system and storage
space.
Although there are potentially a lot of benefits, there is something
about relying entirely on a network that is outside your control, (the
Internet) a service provider that could have a dubious privacy policy
(look at AT&T) and a locked down client which does not appeal to me. I
have very much bought into the F/OSS philosophy and the concept of being
locked into a proprietary system does not appeal at all, let alone
relying on a foreign (i.e. outside my home system) network - especially
with my ISP's service record.
I must admit to being a huge Battlestar Galactica fan, so imagine my
delight when I discovered a community
project to make a space combat game from the same universe! It
combines some of my favourite words - community and game
but the best thing is that it's actually a hell of a lot of fun. The
controls are complicated, as not only do you have traditional control
over propulsion (e.g. thrust and 'flaps') but also manoeuvring thrusters
as well. This means it takes quite a while to get adjusted and I can
hear Starbuck berating me in the back of my head every time I muck up a
turn. I am such a frakking nugget at the moment in this game at the
moment. The Cylon raiders are every bit as dangerous as they are
portrayed on TV, twisting, ducking diving making it very difficult to
destroy, even in a one on one battle. There have been times when I have
had an AI Cylon raider in my sights but the damn thing kept twisting and
turning around asteroids making it extremely difficult to kill. There
are a few issues with the game which are caused by the engine on which
the game is based. Occationally there are graphical clipping errors on
the asteroids but on the whole these are pretty small issues.
>
The only draw back is that you really need to use a game pad to play
this game properly, preferably one with a lot of buttons although there
is a lot of talk on the forums of people quite happily using a keyboard
and mouse. The number of single player missions is currently a bit
limited but that is mostly because only a short demo has been released.
Multiplayer on the other hand is fully implemented thanks to it being
based on an open source port of Freespace2 and is a lot of fun with
several teams having cropped up.
This is definitely one to check out and bookmark, if their future
release builds on the demo, it will rival several recent commercial
games.
With many exciting releases either on the way (*buntu,
MEPIS ) or already
here (Mandriva) I
find myself trying desperately to switch my primary OS to one of these
flavors. The problem is, at the moment, I cannot run Linux as a
standalone operating system without at least dual booting with windows
XP. Whilst my hardware at the moment is (almost)completely supported by
modern Linux my massive upgrade, which is just over the horizon, would
likely prevent me from running a Linux OS with full hardware
acceleration. I believe this is a problem that many gamers face and I
can not see any solution presently. The problem lies in one of the main
uses of my PC - gaming.
I play a lot of games and as such, migrating away from an operating
system like XP or Vista is a bad idea. Even though quite a few games
(Doom 3, America's Army etc) have Linux builds, most games do not.
Whilst API compatibility projects such as WINE
are making excellent progress, it is generally not sufficient to play
modern (i.e. newly released) games properly and with no performance hit.
The major sticking point is graphics card drivers. Whilst these are
reasonably mature for nVidia, ATi drivers (both binary and to an extent
the fglx ones) are substandard. For years ATi has been promising new and
improved drivers but at the moment this has not happened. Whilst I was
going to have a rant about support of new graphics cards, I am
pleasantly surprised to find much improved
support in recently announced drivers.
An option of course, is to goto Linux and buy a Xbox 360 / PS3. Whilst I
think the simplicity of putting a disc in and playing a game (just like
that - no OS, no configuring graphics and tweaking for your hardware
etc) is great and a breath of fresh air, the lack of openness in a
console environment massively puts me off. I like being able to make my
own maps / models etc for games I play. More to the point, some of the
most enjoyable games I have played recently have been total conversion
mods - something not accommodated for in a console environment like
Beyond the red line - a BattleStar Galactica mod. You only have to see
the difference
a few user made mods make
to Oblivion to want to play it all over again.
So as any returning visitor will note, I have implemented a blog
formating to this site. I did this because the majority of what I post
will be in the form of topic news items / blog posts. As such it made no
sense just taking on new entry after new entry and silently archiving
old posts where noone would ever see them again. Whilst that still might
happen with this system, at least it is easier to view previous posts by
category / date. I will be transitioning everything over to the new blog
format given a couple of days.
The software I am using is completely free and open source, as such I
would like to say thank you to the developers by pointing it out to
people who might be thinking about starting their own blog. Its called Thingamablog
and it has a whole host of cool features and a good support forum. The
only thing I dislike is the ping function, which alerts a blog resource
(default is weblog.com) when a blog is updated. Whilst this is actually
quite a nice idea, the site in question is being hammered by spammers
which makes it completely defunct sadly.
I was a bit disappointed to discover the 7.10 release of ubuntu wont be
officially out until the middle of the month. However the team are
making solid progress with a lot of new features now implemented. It
leaves me with mixed feelings, seeing the long list of new gadgets and
fancy things the new release will have as per default. Whilst I love the
idea of Beryl/Compiz window managers installed and ready to use on first
bootup, along with several features like fast user switching and the
search appbar, it makes me wonder what kind of performance hit we are
going to see with the default installation compared to 7.04.
It all feels highly reminiscent of Vista and I really do hope that I am
wrong in this prediction. I have been toying, not quite switching over,
to ubuntu since 5.04 and overall I think the project is going from
strength to strength, however the number of bugs and issues that were
still present, even in 7.04 makes me wonder why these little bugs / gaps
in the interface are not the primary focus of this new release. Whilst
many of the improvements Gnome 2.20 adds to this release will be met
with enthusiasm, I can't work out why a good portion of their
development time is spent working on their PIMs (e.g. Evolution mail
client and Epiphany web browser.) Not all the PIM programs are like this
though, there are some that seem genuinely useful and important to have
in a good window manager. Given the massive use of firefox and mozilla,
in my opinion, some of these default programs seem more like wordpad, IE
and Outlook Express (now Mail in Vista.) Sure they have some user base,
but for a lot of people, they are the first programs to be replaced
either by Microsoft or Mozilla offerings. Perhaps it would make sense
for these programs to be spun off to allow the core dev team to work on
the more pressing issues with Gnome. I am not, however, advocating
removing these programs from official distributions of Gnome as this
would leave a gap for end users who just want Ubuntu to work without
hassle. Sadly I am not experienced (or Gutsy enough) with Linux to
install a bleeding edge version (like 7.10 tribes 4) - I will have to be
patent a little while longer and I guess if I don't like it I can just
move my favoritism over to another distribution. I love Linux
