One of the things both mentioned on the gentoo-user email lists and in the XFS FAQ is that if the power drops on a system using XFS, only the *metadata* is journaled, not the data.
This can get bad fast. With a full 30 seconds between disk updates, having the power cut means binary NULLs in any file updated since sync. (http://oss.sgi.com/projects/xfs/faq.html#nulls)
Short version: If you're using XFS, make sure you are careful to have clean power available, unless you don't mind file corruption. If no clean power is handy, stick with the usual journaling filesystems.
Okay, so math is hard. We know this already. But posting every stinking proof we can write isn't a good teaching tool, though it's great for human achievement and such.
My math education was a pain for one major reason; it was harder than it had to be.
The lion's share of professors I ran into didn't know how to teach. This means that, instead of getting explanations, I got dense texts like Rudin (ask your local math geek) pretty much read back to me.
While it *is* hard, and that can't be gotten around, it works a great deal better if you explain things instead of the drone of "defintion, theorem, proof" that passes for teaching in some universities. It's great mathematics - and piss poor teaching.
It says a lot that this dear lady is representing *publishers*, not researchers. This isn't about making sure Doctor Not-Altogether-Evil gets his money for his research. That's what grants are for. These people want rich people in suits who own printing presses to get richer. While not a bad thing, they can pry my library card from my cold, dead corpse if that's their logic.
Now, I don't particularly like what AOL Time Warner, Microsoft, or any other media conglomerate, but I have some respect for them. Like it or not, Steve Case, Bill Gates, and Andrew Grove are excellent businessmen, and I'd rather not see them dragged out into the street and shot quite yet.
Here's something to understand, though; the people on these lists, the programmers, web developers, computer scientists, and generally smart people - we're not an easy market to capture. This is why the SciFi channel isn't carried on basic cable in a lot of states, despite the people around here who adore science fiction. The market that *is* easy to capture is the one we aren't, and AOL and the corporations are doing a wonderful job of capturing it. And, while we may not like it, we're not who they want.
And we're not in any real danger as people, I don't think. Consider for a moment, Jon, trying to take this to its final extreme. Do you really think that your friends, family, or even just a well-meaning stranger won't come and help you if some businessman comes raging into your home searching your house accusing you of whatever crime he cares to?
Nor as a niche. Bear in mind, if we don't like it, AOL has a tough time running without the resource of human intellect. Sure, they might be able to run the business, but these outfits need web developers and programmers. They can't be too careless, or if they are, I, for one, would like to know why.
On a similar note, I haven't heard word of Andover, Red Hat, or the FSF being bought by the "corporations" - and I'll be rather surprised if the FSF ever gets bought out, because it's an ideological thing, not a business one, despite whatever money might be gained from it. Corporatism is a danger, but you're forgetting that these corporations are being run by individuals, just as mortal as you and I. I don't think Gates wants Case beating his door down, and if he does, this trend won't stick around long enough to say goodbye. I really don't think we're in critical danger here.
