In principle, using LVM 2 system it's easy. Get database to consistent state on disk, take LVM snapshot of the logical volume involved, resume database, run dump on the snapshot, take out the snapshot when no longer needed.
Beauty is that the size of snapshot is size of delta that is caused during the backup; therefore, this is practical for almost any sized database.
It's not very good thing. At least compliant DNS implementations will be doing 144x as much traffic with them as before (assuming infinite load; of course, in practise they will have bit less load).
I don't see the point myself, domains are not supposed to change every minute anyway.
That's what idealists would like to think. However..
The _reality_ is, quite number of recent RFCs, and even larger number of I-Ds that will eventually become RFCs are 'licensed on fair and non-discriminatory basis'.. just like RSA of old, which definitely didn't mean cheap or free:-)
Actually, human eye has trouble focusing on blue color, and therefore using it for anything except decorative blobs is cruel to the user.
That's one of the basics of UI design, and STILL lots of terminal emulators have some asinine blue colored font themes, and color-ls has blue colors on some entries, grrr.
My original iPod (5GB, bought when they came out) has fallen to pavement from my pocket half dozen times (lousily designed jacket pocket), fallen off table once or twice ('oops, headphones were connected to it?), and it's still kicking..
Downside? Few megabytes of bad sectors that are non-trivial to isolate ('create tons of files hoping directories do not get on badsector zone. clear cache. read files. if firewire jams, file is bad. disconnect-reconnect ipod. otherwise remove file. repeat.'), so it's now about ~4500mb out of original 4800 or so..:P
(Probably 20+ real bad spots on disk, but I'm too lazy to isolate them to the ~few-hundred-k to few-megabytes size they are, as firewire reconnect gets old after awhile).
What's so great about 'eternal' TV series ?

Once upon a time I was almost addicted to Star Trek, but after liking TOS in historic times, I got quickly bored of TNG (maybe 3 seasons), DS9, Voyager and Enterprise (roughly 1 season each). Babylon5 was only sci-fi recently that seemed mostly worthwhile, thanks to actually having a plot that spanned it's entire runtime.
Fundamentally I see the problem as basically this: The series go for 'eternal' runtime (just take a look at X-Files), they can't really shake the status quo (like actually having a plot or something that actually affects the environment much).
Me? I'm just going for anime these days, even the most successful ones have FIXED duration, and probably thanks to that usually great plots as they don't need to worry about the next season.. (Ok, some do get extra seasons but it's the exception, not the rule)
Would you have been more happy if the original poster stated that probability of one or more fatal failures is 1-0.99^100, e.g. 0.6339676? (That's roughly 2 out of 3, which in my book is fairly certain)
Without trying to offend you, you sound slightly clueless.
Why would inactive applications use processor resources? (Hint: something called 'scheduler' in most operating systems prevents this. And even WinCE has one, I heard!) Obviously, if you're using 10 MP3 players at same time they might use the CPU, but having Pocket *** in background definitely doesn't.
Same with memory. Sure, they use memory, but that doesn't slow processing down as the devices lack swap. Unless you run out of it, in which case processing obviously also stops..
The truth? After playing a bit with the development environment of one, and owning IPaq for awhile, I can tell you that WinCE is monolithic horrid beast which has order of magnitude larger CPU usage / memory footprint than Windows 3.11 for gods' sake, meant for 'embedded' use..
Well, assuming 100 percent false positive rate is okay too, I can sell you box that detects 100 percents of terrorists! And cheaper than what the govt pays for it's system, I bet! (just 100M $ for you, my friend..)
That explains it I suppose - I have dislike of using my time on food preparation, so I typically buy premade or more typically eat out:> (and well, there's healthy and unhealthy restaurant alternatives)
Admittedly, at some point in time I MIGHT start cooking in case I get really bored of all potential ethnic varieties of food available.. Unlikely at this point, anyway.
Huh. I've met my share of Indian Ph.Ds in my day, and almost anyone had horrible accent (i.e. barely understandable). Even my finglish (finnish+english pronouncation, like Linus!) was apparently more understandable to native speakers:)
It's pretty much question of lifestyle. Back in the heydays of tech boom, I turned some 60-80k$/yr job offers in the 'valley down because of heinous cost of living (would've had much less money available than I have now in.fi).
How do you manage with ~400 eur/mo? In.fi, that's about what I spend on food alone per month. And there's transportation, clothing, etc. Especially if one has own car, 1000$/month isn't too much, and in States you really don't want to be without own car - you aren't citizen then:) (I caused lots of wonder AND suspicion when I walked to office when I was working in 'valley, despite the distance being just 2 kilometers or so)
I was looking forward to something like this happening (Apple releasing a model that has smaller display, and thus better form-factor and also lighter), but the weight is DISAPPOINTING!
I admit that some weenies still live in world of physical media (superdrive), but something like my
Dell Latitude X200 running Mac OS X would've
been reason enough for me to Switch!. As it is, I rather take (roughly equivalent) Dell that weighs 1.8 pounds less (X200 is 2.8) running Linux than Powerbook with better OS..
America is the only industrially advanced country NOT to have ratified Kyoto agreement, whose whole point was to prevent global warming.
Bush is in the pocket of the people who got him to power (=some greenhouse effect advancing corporations), so therefore I am not very surprised by that.
I picked up the whole set, except for Silmarillion, off some site mentioned in Slashdot post about three months ago. I think it should be legal, as long as you have paperback copy, although considering how insane the US copyright laws are, I bet it isn't..:-P
Uh.. is it just me, or does everyone want things to go _slower_? In another words, even on 28kbps modem, I'd usually rather have _all_ deja query results fetched, and have some transfer wait, rather than (N results found. )..
Maybe I'm just graitutuous waster of bandwidth but I'm starting to lean heavily towards writing proxy that _automatically_ grabs all links' content on a page when I hit the main page itself.
Depends - my Linux (at one time) required boot-time entering of password for the on-the-fly encrypted filesystems to work.
I got annoyed by it eventually, though, and moved to less secure way of just having my "data" filesystems encrypted and mounted/unmounted interactively.
In the end, though, nothing can really substitute for physical security. Bios cannot be trusted (reset CMOS settings jumper anyone? cutting battery off?), lack of floppy can be trusted to a degree, and non-encrypted filesystems cannot be trusted at all.
So, if you want machine without attendant to boot properly, physical security cannot be overlooked. If you're willing to enter the filesystem decryption password every boot, security from physical things becomes better, but not total (keyboard snooping anyone?).
My point was, monolithic kernels on Linux, at least on i386, _DO_NOT_WORK_. You _have_ to fuck around with modules, or alternatively "learn to compile your own kernel". I consider neither good approaches for the "Linux Newbies", and therefore _working_ i386 monolithic kernels would remove one confusing section from most "Linux for dummies" books, that is, the kernel compilation/installation part.
Even as non-newbie, I've had great deal of pain dealing with some-modules-that-do-not-work-as-modules, and the damned 640k/1M boundaries the current loading architecture sets for the "monolithic" kernel.
Example: My current kernel is 613kb[1]. I cannot even include ext3fs for root device purposes to it without hitting some mystic boundary (make bzImage works; after boot, it says "out of memory". huh).
[1] ext2+nfs+reiserfs fs:es, couple of network card drivers - almost all irrelevant is done via modules. reiserfs-as-module did not work, nor did nfs-as-module at most recent try. And yes, this is frigging "stable" branch.
This may be flamebait,/. being bit Linux-oriented, but why in gods' name cannot Linux adopt boot loader scheme like that of *BSDs? I haven't had any need for moving away from GENERIC kernels on OpenBSD:P
Linux would be definitely easier to use if you could just have "massive" kernel, without modules, IMNSHO.

My mind boggles at the last paragraph of yours; ANYTHING you can represent in a text file, you can also represent in RDBMS, and usually easier..
;-) (all it takes is basically mapping of (article,user)->state, which can be simply one more table).
