You need to explain the "newer" in "the newer $(...) construct". This is the computer age, and this construct existed in ksh at least for 15 years, so I hardly can call "new" something that old. It and the backticks are both old now, and what you say is old news. Like, "I got bored of diapers so I learned to pee in the toilet".
This is too obvious. You better go to someone who has the habit of running as root all the time, and tell them something along the lines:
"I'll show you a nice trick. Do the following:
mkdir -p a/b/c cd a touch a1.a0.a9 b/b1 c/c1
Now, there are both hidden and non-hidden files in 'a'. You know that if you do a 'rm -rf *', it won't delete the dot-prefixed ones, don't you? The trick is to do a 'rm -rf.*'. Try it."
The disk devices, as presented by the Linux kernel, are block devices and they go through the buffer cache. If you want (on Linux) to access a block device as a raw device, you should use the raw(8) command to bind the block device to a raw device, and then you have to obey alignment restrictions (much unlike various Unixen raw devices, available by default).
But in no OS (that I've seen and differentiates between raw and block devices) raw devices can be mounted.
HQ to JWSmythe: Uh. John, the time machine fucked up again. Our calculations indicate that you managed to get to the US of A, but this is NOT, I repeat, NOT the 1970's, and cars don't use carburetors anymore. Stand by for high capacity transmission of missing technological advances in 3, 2, 1. Godspeed, John.
Do you imply that if there are in-memory dirty data for, say,/dev/sdb1, and I do a dd if=/dev/sdb1 of=somefile bs=64k then I get what's in the disk image without the in-memory data?
If yes, because it seems you do imply that, you need to check your basic operating system knowledge. Really.
Otherwise, per compression, resizing etc, you do have a point.
As the Greg House TV character once asked a patient: "Would you prefer a doctor that holds your hand while you die, or one that ignores you while you get better? Although I suppose it would particularly suck to have a doctor that ignores you while you die."
I somehow can't even grasp the "30 seconds UPS backup... for a quick hardware shutdown and to finish writing to the disk" idea for Windows. It's not hard to imagine a CRT with burned phosphor permanently saying "Windows is saving your settings".
One should never, ever use XFS on a non-UPS-protected system. It's a great filesystem, but if you don't get the time for a sync of the in-memory structures, you're screwed.
I always wonder why I can't apply this kind of logic to torrents with that one file stuck at 99.98%...
Um. So you have a file that's completely downloaded except for 16kiB, so you'll have to try at the most 2**131072 combinations for brute-force reconstruction. Of course, on average you would get a match after only 2**130911 attempts, which would be wrong. I'd suggest you don't wait up.
A fit-PC has two ethernet ports. I have a fit-PC, and do use it. Not as fast, possibly, and double the consumption, but what the heck. It works. Although it probably is more expensive. Also, why are we talking about old news? Oh. It's a slow day for slashdot.
I'm a proud member of a group dedicated to fighting excessive acronym usage - we're the AAAAAAAAAA (the Australasian And American Association Against Any And All Acronym Abuse).
Well at least it's not a goddamn TLA. I really hate TLA's.
Um. It *is* a TLA. Just count the letters.
You have exactly 10 minutes to reply and suggest that *you* knew that already and *I* missed your joke:)
That's not Unicode, that's ISO8859-1. And, for some strange reason, with your "OE" there, I think you wanted to have the "Latin capital ligature OE" character, which does not belong to ISO8859-1.
On a sideways, kind of off-topickish view, if my name was Bitchard I would love to just undersign (like you do) my posts when replying to annoying people and get away with it. Legally, I mean. In a court of law.

Instant success.
Well, they still answer to bug reports. Sometimes :-)
The last update to the bugs page has been in August.
But what's taking them so long for a new version, nobody knows.
I've heard that they had issues switching to a new graphics engine.

You must really be smoking crack.

One thing for sure: broadband connections on Mars will be capped.
A ha! Erlang threads. There's a difference to OS threads.
If you're writing a server to handle 100,000 connections simultaneously you probably want to use threads.
A single process (single-threaded or multi-threaded) would have OS limits on the open file/socket descriptors much lower than 100000.
Typically you would spawn several processes, and then do a
man 2 select

XFS or JFS might be perfectly good solutions

OK, I get it. There's software free as in beer, free as in speech, free as in jazz and free as in Reiser.

He could mean "threads per kernel task", but I wouldn't fathom how one controls that. In any case, I believe you are right.

Both. Michael would stay in the bigger new state, and Billy would be in the other.
How did this get modded insightful? Where can I buy a new Mac with OS 9? OS 10.2? 10.3?
Where can I buy a new car without all these side airbags?
Where can I buy a new cellphone that only makes calls and nothing more?
Fixed it for you.
what if an unverifiable, untraceable voice announces in your ear "rob the bank or I shoot your wife", what would you do?
I would make sure that they know exactly who my wife is, in order to save innocent bystanders.
There you guys sit, all laughing at me at pointing and jeering at my Tinfoil Hat 3000(tm), but look who's sitting pretty now! Ha! Fsckers!
That's it. A tinfoil hat covered with corn beads will work as a protector / detector system.

I just wanted to express my appreciation for the optical/worplay joke you offered to us. Thank you.
