I would agree with you except for the fact that when you need a feature that does not come with stock kernel or even distro-kernel you are mostly out of luck.
The number of patches those distros apply make almost impossible to incorporate extra pacthes.
The scenario you've mentioned is probably OK to use a software RAID. I use it in a production enviroment without problem with a higher stress that your setup will probably have.
I'd suggest you to consider the following items: a) cooling system - those HD can generate a lot of heat. Buy a full tower case and add those HD coolers to make sure your HDs stay cool
b) Buy the HDs from different brands and stores - RAID5 (either hardware or software) can recover from one drive. If you buy all from the same brand/store chances are that you end up with 2+ drives with the same defective hardware
c) cpu - if you are going to use this number of drives the processor will be a majo bottleneck. Do not forget that RAID5 XOR your data to calculate the parity.
d) partition scheme - use smaller partitions and group them together using LVM. This you help you to recover from a smaller problem without taking a lot of time to reebuild the array
I was wondering if we could switch the approach slightly.
All underlying fs seems good on paper and all seem to have strong/weak points depending on the view/desired usage.
Since there's no solution that fits it all (speed, reliability, price etc) under all possibile scenarios lets try to focus in a particular one.
I have a server for which I can have small downtime If I need to replace a defective drive, but can not tolerate to loose data or extensive fsck if for some reason it locks up.
So, since hard disks die from time to time, and hard disk space usage tends to increase which is the "best" solution (considering only linux and not high-end solutions) ?
Use a RAID controller and disks (either SCSI or IDE) to have the "high-availability" and LVM to have the dynamic increase ?
If so which configuration would you recommend for a 100 Gb solution ?
I am assuming a software RAID0 for the OS (/boot or the entire OS) using ext3 or reiser for the partitions. RAID5 hardware and LVM for the SCSI or IDE (not both)

I don't trust 100% in that. If you see the number of outside programmers you will see that mozilla still depends of a "corporate" funding.
I think that if aol stops, perhaps IBM or another vendor would "take over".
Well, There are at least two encoders for PHP which can provide the binary/speed feature that you want. In PEAR and phpclasses.org you can find tons of classes which do provide good functionality such as access do DB with the pagination feature.
Nowadays most of the videos (trailers) in quicktime you find asks you to choose bandwidth(size) and opens a small quicktime where you click to play and it starts downloading.
How can I download direclty so I can play back later ?

Hi, I am trying to download but it seems that most users download and simply stop sharing...

The problem is that security upgrades seem to be slower or non-existant for the "legacy" distros.
Imagine having to upgrade 100+ clients every year !

Indeed, at least it shows that the person with the PHd has enough patience and interest in a subject to cope with a 4-year-study.
Usually you have to get away from the everyday technology to end up with a frontier knowleadge which probably won't be usefull for regular companies.

Hi, perhaps in a wonderland with gigabit fiber connections directly to your home this will happen.
But how about the other 99.99% of the population/world ?
From my point of view the bandwidth and compression are not evolving as fast as ours demands.
If you plan to retire your DVD with VOD how about when blue-laser HD-DVD becomes mainstream ?
I think we will always be in that game.
Remember when we thought that 10 Gb HD would last forever ? It's the same principle.
By the time someone copes with that requirements we push the bar a little higher.
Besides KDE 3.1 and some minor upgrades in other packages what can expect as really new/cool feature ?
One of the things that could help it to have a list (albeit non-final) of the planned features so we could decide to download and try.
.something updates in other packages.
It's rather frustating download just to find a new KDE version of

Hi, I was wondering if the kernel included already has the low latency patch applied. If not can we get it from rawhide ?
I could not find a chanlog/news anywhere
BTW How do I convert an ext2 to an ext3 ?
I've tried to use tune2fs but I am not quite sure it did it ok...
