Since the main difference between a RDBMS and MapReduce seems to be that the former is most suited for structured data and the latter best suited for unstructured data, it might be a good fit to use them both. And according to studies, it might be that north of 80% of our data is unstructured. This has been a big topic in data warehousing and led to the start of the whole DWH 2.0 thing.
So the fact that MapReduce is used in massive parallel processing machines like the ones from Greenplum (as quoted from the article) is not as bad as Stonbraker and Co. seem to think.
First of all there is Bryce 3D which is available from corel (at the moment). It is 'frowned' upon by many pro's but it gets (most of) the job done. Also its terrain editor is great.
And if you just want to learn the basics, then you can do a lot worse than look at PoVRay, which is free of charge. It has a very peculicar interface, since it's entirely text based. But somehow this gives you fantastic control over your scene. See http://www.povray.org for some amazing examples.
Perhaps it's just the processors, but you'd think my G4 would be faster than my PIII
A collegue of mine has a TiBook G4 500MHz, with 1MB level 2 cache. My TiBook 667MHz has just 256MB level 2 cache and believe me, all java programs are much faster on his machine then on mine. Where my machine is slower than my PIII 600Mhz, his is faster, all with the same class-files. So it might just be the processor.
Well I have to agree to that. At work we use both Windows nt4 machines and TiBooks. We have a local cvs server on the windows network. And it's completely transparent to checkout netbeans'.java and.form file on both machine types. Or, to go with the apple motto: It just works.
The new release of netbeans (3.4) can autofill any code from any.jar file or directory. So, although I must confess that I do not know anything about JClass, I presume that this is a Useful Feature to you.
Beans can be treated as components and added to the component toolbar, from which they can be dropped onto your form.
But I got one issue with it and that is that I
cannot compile from within emacs and use C-x ` to go to take me to the line in error.
It seems to me that all processes run from within emacs don't get to an end.
If you know a work around, then that'll be great!
It allowed me to copy files that were to large for the W98 gui to copy. And they were only 4Gb large.avi files! Phew, was I glad I had some dos lying around!
So here we have the reason why all my techie funds are worthless at the moment. Maybe you all should go back to work and use those long hours you make to be productive. Then, perhaps the stockmarkets will pick up and break record highs again.
Oh, and by the way,
Here in Amsterdam (EU) I work for about 36 hours a week, with 23 days off a year plus banking holidays.

Luckily for you and everyone else who's using VB, that Micros~1 has devised a way to keep the legacy problem relatively small.

It is indeed a lossy compression scheme. However, the compression is applied when the data is captured with the lens[1] and transferred to tape. Once it is on the tape it stays there. With the Firewire connection you can copy the data from tape to your computer, where you can edit it. All DV-Capture cards come with software that allows you to write data in native-DV format back towards your camera where it is stored on the tape. In this effect the DV-camera differs not much DAT-tapes.

RA the sun god?
I thought that he was called Aton. Pharao AchnAton tried to make Egypt a monotheistic state with Aton as its god. His successor was - originally - called TutanchAton, or Incarnation of the Sun. The old priests, who had Amon as main god, didn't like the monotheism and went back to their old ways. Then Tut changed his name to TutanchAmon.
Oh wait, this was centuries after they build the piramids, so ignore what i said.
No, he is probably storing them in DV format which, IIRC, generates something like 3.6 MByte / s. The DV format is an adaption of the MPEG format, creating a constant byte-flow. I suspect that storing in bitmapped format would increase the size even more.
Well lets do the math:
(Assume bitmap)
4.7GByte / (22 minutes * 60 seconds * 24 frames/s) = 154 KByte / frame
This is true-colour, so divide by 4 to get the number of pixels: 39321 pixels / frame
Let's get a reasonable size e.g. 512 pixels by x pixels. To get an almost square picture, the resolution must be something like 200x197. The DV-standard is more like 780x560 (IIRC).

... a 300MHz AMD K6-2 in it. Lets see what a decent 3D card does in that!
Exactly, this is what I would like to know myself. What would the performance boost be for drawing and rendering 3D-pictures and animations if I upgraded my 1MB S3-Trio card to an OpenGL 32MB card? My opinion is that most of the work would be shipped from the CPU to the graphics adapter, so there could be quite a big improvement.
However, looking at the benchmarks in the article, it seems that the GeForce 2 GTS on low resolutions is hindered by the CPU performance. So is it a realistic idea to spend a few quid on a new graphics adapter instead of spending a lot more money on a completely new machine. I mean, my current machine is a compaq 166-MMX and does everyting I need quite satisfactorly.
