Here is why you should consider Very Carefully before getting into fractal generators!!







Crap.

Lots of stuff to burn to CD-ROM this weekend...

There are also many areas of the Windows system and it's settings which could be checked to see if you are using more disk space than you really need to.

Just by going to "Power Options" within Control Panel, and then going to the Hibernate tab to turn off Hibernation will most likely free up a gigabyte or so (depending on your particular system).

And another item is within "System Properties" of My Computer, under the System Restore tab, click the Settings button to see what is being allocated there.

Yup...

I've disliked windows since I first saw 3.1 

I already did the system restore thing long ago, but I never knew about the Hibernate feature using that much space!  I'll try that too!

Thanx!!

Much space freed by deleting ALL those 800 MB avi files complied from 1,000 Bitmaps.

I NEED to learn about codecs for this.

I can't seem to hit anything below 80 to 100 MB per minute and maintain image quality.

Further compression ruins things.

I've seen 10 MB files that ran almost 2 minutes and looked Great!

More research I guess.

I made a serious topic in the "Let's Collaborate" category for that. I only posted the image here in the Humor section because I thought it was funny.

I had a TI 1,000  for over 20 years before I upgraded.

Wrote Lots of programs in Basic (mostly creating sound effects for videos).

Never filled the hard drive!!

I'm running out of Virtual Memory constantly now...

Weeeeeeeeeee!

Yeah, and clean those temp folders! - but burn CDs before you end up with too little drive space to burn a CD! LOL

Just for the record, you should defrag before burning backups - and you need some free space to do that! Also, the best way to burn a large number of smaller files is to write an iso to the hard drive first so that the burn will go smoothly and you won't get a "coaster" instead of a good CD. CD burners must have a perfectly steady flow of data, and scattered, fragmented files cause a lot of hard drive "seeking" activity that can choke the flow. One tiny disruption and the CD is dead plastic.

I have the same problem. I can never bring myself to compress my 24-bit BMP images to a lossy format like JPG either and formats like PNG are harder to write save/load code for. I should really go find a library that does it. I just keep buying more and more external 200GB USB hard-drives smiley

modern hard drives can keep up with cd and dvd burning speeds quite well; this is especially true of large files.

that was back in the days of 4x burners smiley

Actually, this problem can still occur quite often even with newer hardware, systems, and burning software.  I have a 2-GHz DELL Dimension P-4 with a Samsung CDRW/DVD SM-332B, and use Roxio's CD Creator version 5 on it.  I burn a lot of CD on that machine, and out of a few hundred that I went through last year, I have about 25 that are now useless.

And It happens more often if I use Microsoft's CD burning options built into the Windows-XP operating system, no matter what the hardware is.

there certainly is a big software factor involved; i recommend deepburner - it's free and really good, especially when it comes to buffering. this is what makes nero considerably more reliable than other burning applications - when you use a large buffer the hard drive can catch up when reading big files, the burning isn't affected by small system stalls, etc.

i used to get the same problems when using adaptec's easycd program (i think it was called). just like with download managers, there's a lot of crap software out there smiley

Yes, Nero is a fairly stable and fast application, and easy to use.

It's been about a decade since I used Adaptec's program.  But back then, it was pretty good on my system.

ha, my computer is far from "perfect" smiley what is a perfect computer anyway? "one day, computers will be fast..."

i've used many computers, from a greenscreen apple to my current powerful-but-not-quite-state-of-the-art desktop machine; i'll be using a 1.5ghz laptop for commercial coding work soon while "on holiday", and that's beside the point anyway - no machine since 1997 (which is roundabout the time of adaptec's easycd creator paul and i were discussing) should really have difficulty burning cds using decent software.

edit: for what it's worth, i'm also having storage problems on my limited machine, thanks in part to fractal animations - 1 second of uncompressed hd animation takes 150mb!

With the increase of videos and animation, PCs will soon come standard with TerraByte hard drives.  (Personally, that is too little for my current needs.)    wink

i'm sure you now see, with the proverbial 20/20 hindsight, how fortunate you were not to make that purchase! those crays were absolutely horrible to program, due to the fact that they cut so many corners for speed; for example they didn't support ieee floating point arithmetic, which of course means that while your computations can be fast, they can never be accurate! on some crays it was so bad that 1.0 * x != x, something guaranteed (with stronger bounds) by ieee754.

even in 2006/2007 there are programmers snubbing the utility of floating point computations... but that's another matter wink

another apocryphal (american) quote: "all the speed in the world won't help if you're headed the wrong way!"

modern video compression techniques (mpeg4 avc, wavelet methods, ...) can squeeze some ridiculously high quality hd video into just a few megabits of bandwidth. it's extremely impressive really; i've been reading about video compression for longer than even ray tracing (which in turn i've studied about 6x longer than fractals, in years) and it's just incredible to see how much progress has been made approaching the true entropy of the video signal. thanks to this i get away with 300gb of storage cheesy
