I wonder if the real purpose of Youtube, which costs Google at least a half-billion dollars each year, is really to take load off the Gmail system. Imagine everybody e-mailing those videos around to one another! In principle, Google could share storage for attachments that match, but it would be expensive just to determine that they match, and people would be tempted to alter them enough to reduce such a benefit, e.g. with annotations. With Youtube, there's just one copy, and no scanning.
I tried installing an Nvidia 9400GT video card ($70). The current X.org nv driver claimed to support that model number, but didn't recognize the card; evidently "ver1.1" is different. It's curiously difficult to get the nouveau driver installed in Debian Sid with a new kernel. With no assurance it would know the card, I gave up and went back to the old motherboard i945, which I estimate consumes maybe 10% of available memory bandwidth.
Each time Firefox crashes, when I restart it I have to turn off my network interface so it doesn't eat my machine reloading all the pages. Couldn't there be a mode to leave those pages unloaded until I'm ready to look at them?
