Heh.

There's more esoteric ones but I'll let you figure out for yourself. 
Hint: view it's called. :P 

When you do get the hang of all of them, if you got some time at hand and say 
you're willing (during say weekends or sometime), write up a blog comparing 
feature sets, speeds and/or beautification of each one you tried. It could 
immensely help other linux users. Ofcourse, that's only if you want to. You 
don't have to if you don't want to. ;)

Typo - The other way round ;)
i.e. - 
"the software that run using wine may not be as fast as the Microsoft windows 
equivalents because of extra overhead underlying the function calls from wine 
dlls<->glibc<->kernel (I could be dead wrong in the water here! If so, please

gwenview isn't too bad either. It's the default image viewer in Kubuntu(KDE).

Picasa runs off wine (reverse acronym for Wine Is Not an Emulator). Basically 
it's a software library that provides the 
same/atleast_try_to_provide_the_same feature set as win32 dlls (Shared 
software libraries in windows) so that windows programs that depend on win32 
library/s can instead link into wine libraries and use the dlls there like in 
Microsoft windows. Hence, I believe, the software that run natively on 
Microsoft windows may not be as fast as the wine equivalents because of extra

Hope that's not too hard to understand from technical perspective.

Greetings Martin,

I just downloaded and tried gThumb.  My first impressions are that it
slidescreen's very much better than both Picasa & F-Spot.  Just as you
said.  I will spend some time with it to see if I will adopt it in
favour of the others.

Much of the technical discussion that has been going on is well above
me.  But I'm trying to digest some of it. Maybe one day I too will be
able to converse so technically?

You say that Picasa for Linux is really an emulation using intergrated
Wine?  And therefore some aspects of the Windows version are
compromised?   Or were you assuming I had loaded Wine in order to run
Picasa?  Might be the same thing really?

By the way gThumb is available in Hardy.  No need even to use Synaptic.

Thanks for your help Martin

Re: Wireless USB Adaptor

[Joel Addison]

I have a Belkin Wireless G USB adapter (F5D7050) that works well with 
linux. It was up and running as soon as it was plugged in, with no 
configuration necessary.

I also tried a Billion BiPAC 3012G, however it overheated and the 
connection dropped out every minute or two. If it hadn't overheated 
though, I am sure it would have worked well, because as with the Belkin, 
it worked as soon as it was plugged in.

Hopefully that helps.

The Linux Australia Planet [0] is usually pretty good

If you are into web development there is sitepoint.com blogs[1], some of
which is from here.  There is also builderau.com[2] which can have some
good stuff.

There is APCmag.com[3] which has been going down hill steadily for a
while.  I have decided not to renew my print subscription for a few
reasons.  The last straw was when the online version called me a fatty
(with a pic) in a piece about the Google Developer Day.

The Age technology[4] news is slashdot repackaged /. lagging by upto a
week.

I have 50 or 60 feeds I subscribe to, so let me know if you need more
geeky news sources.

Not Aussie, but I have both ArsTechnica and Phoronix in my RSS reader:

http://arstechnica.com/
http://www.phoronix.com/

Ars covers the occasional Linux bit, but is a good industry-wide news
site.  The authors are highly technical, so the news is generally of a
better quality than sites like ZDNet and others, who quite frankly make
me embarrassed to be in professional IT sometimes.  One of the article
writers has a background in micro electronic engineering, and their
articles on new CPU design are very in depth, but still easily readable
even for those without similar qualifications.

Phoronix is dedicated to Linux and Solaris, and has a host of reviews
and benchmarks of various Linux distros running on new hardware,
including things like WINE to native Windows comparisons, etc.

F-Spot is a 2D image viewer.  It does not use textures.  You are

This accelerates drawing pixels to the framebuffer.  This is a generic
feature that is done after the application passes information to the
internal GUI system.  And once again, this has been around since the era
of the Tseng Labs ET4000 (released 1995) and eariler.
http://en.wikipedia.org/wiki/Tseng_Labs_ET4000

Once again, upgrading from a Radeon 9250 to a newer card will do squat
for the problem the OP is facing.  These cards are capable of throwing
HD resolutions of pixels at upwards of 1000 frames per second to the
screen.  I can assure you now, the bottleneck the OP is experiencing is
not with 2D acceleration.

| For example Ive noticed a good improvement with mplayer using xv
| instead of x11 as an output driver

Of course you have.  This is because Xv via Xv-MC (X Video Motion
Compensation) can utilise specific instruction sets within your video
card to accelerate the decode process of MPEG2/VOB/DVD encoded video.

Once again, the OP is not decoding MPEG2.  The OP is displaying flat,
single-frame images.  This is not accelerated in any way, shape or form
by the video card.  The decode is done entirely by the main CPU in
software.  The only 2D acceleration occurs once the image is decoded
into raw pixel information, and from there injected into the frame
buffer.  This part happens in the last 0.01% of the process, speaking
from a CPU effort / time scale point of view.  And once again, changing
video cards here will have an effect so negligible that no human eye
could perceive it.

| If you have sourcs for further reference Im generally interested, thanks

Wikipedia mentions a little:
http://en.wikipedia.org/wiki/Graphics_processing_unit#History
http://en.wikipedia.org/wiki/2D_computer_graphics

But doesn't go hugely in depth, mainly because the process really isn't
that complex.

If you want to find out more about other acceleration such as MPEG2 and
MPEG4 acceleration (which is unrelated to "2D acceleration" as it refers
to normal drawing of pixels to a frame buffer), these articles are a
better read:

http://en.wikipedia.org/wiki/X-Video_Motion_Compensation
http://en.wikipedia.org/wiki/Video_Acceleration_API
http://en.wikipedia.org/wiki/Nvidia_PureVideo

There is plenty more on the subject of accelerating certain
specific/specialised 2D graphics via 3D calculations, such as SVG,
PDF/PS and Flash/FLV acceleration via 3D calls (Direct3D, OpenGL, etc).

But again, this all refers to something completely different to what
happens when you display a humble image to your PC monitor.

Thanks to all who answered.
it seems that internode has many satisfied customers amongst the posters.
By now I checked the plans from inernode and iinet and by now iinet
has more of what I was looking for than the node. So unless on of you
has a good reason not to use iinet I will go with them.

Thanks again to all out there helping!

Re: Linux Servers for Infrastructure

[Null Ack]

Hi Daniel, Im also interested inthis topic too. I was trying to get
more of an in depth understanding from a forum post I did here:

http://ubuntuforums.org/showthread.php?t=848194

It would be great if you shared your views on that

I thought there was a generic 386 only, other than the AMD64, server
kernels, IA build etcetc

Thanks again

Re: Monitor problem

Yes, but what about texture compression?

And accelerated direct rendering in 2d?

For example Ive noticed a good improvement with mplayer using xv
instead of x11 as an output driver

If you have sourcs for further reference Im generally interested, thanks

You appear not to be familiar with exactly what "2D acceleration" is,
how generic it is, and how little it has to do with the actual
application level number crunching.

2D acceleration has been around since the days of PCI graphics with
256KB frame buffers, and yes, even in Linux (or more correctly, XFree86
and today Xorg).  If you own a card made in the last 10 years with
enough frame buffer space to hold your entire resolution at the correct
colour depth [*], upgrading to a new card will do absolutely nothing for
your application speed when dealing with programs such as F-Spot, GIMP, etc.

The recommendation was to upgrade from a low-end ATi video card to
something better to improve F-Spot performance.  This is incorrect, and
will not yield the performance benefits desired.  The bottleneck is
somewhere else.  My guess is F-Spot is doing some heavy reading or
pre-caching of images from the disk on first start, which is usually the
case for such programs.  A lot of this can be disabled in the
application preferences.

[*] Some maths for you:
"Full HD" is 1920x1080 at 32 bits per pixel.

1920 pixels * 1080 pixels * 4 bytes per pixel / (1024^2 bytes per
megabyte) = 7.9MB

It requires only 7.9 MB of framebuffer space to store a screen worth of
information at HD resolution with full colour depth.  Anything more is
totally unused when dealing with programs like F-Spot and other image
viewers.

The Free Software drivers for both NVIDIA and ATI cards support full 2D
acceleration.  I've used this driver for quite some time on my very
low-end ATI card (a AU$38 Radeon X300SE) and have perfectly acceptable
performance in paging through 5 megapixel photos.

Paul

And do you have DHCP on or do you have to statically allocate your IPs?

Abuntu,

   Just installed ubuntu 8.04. having trouble getting  on net
through  through a network DI router   system do I need to install a
different  driver 

To get on net and could you advise as to where I can download same.

 
Bob.

Re: Monitor problem

[Martin Visser]

I would disagree here. For display photographic images, almost no work is
being done by the graphics card. Any basic card running as a frame buffer
(with say 8MB) wouldn't perform much different from the 512MB card that
seems to be standard. It is really only in 3D games or 3D display managers
like Compiz where they will have appreciable benefit. With the right program
your card could easily display 25 photos per second with no flicker - this
is what any movie player needs to do!

Both Picasa and F-spot while feature rich, are probably rely too much on the
CPU to do their work. Picasa is basically a Windows program running in
emulation (using WINE), and F-spot is written using mono, which is a clone
of the .Net framework. Probably the slickest way to view photos (and do
basic manipulation) is gthumb. It used to be the default photo program until
Hardy (you may need to install it from synaptic if you did a fresh install
of Hardy).

I just did a 3-way test of the above 3 programs doing full-screen "paging"
through some photos and gthumb is far quicker (at least 3-4 times) than the
other two for this function. (I am viewing 2592x1944 images on a 1400x1050
so it has to do non-integer scaling/dithering to display these - which is
where I think your problem was occuring.)

Regards, Martin
