The street is a public area. You have a right to say just about anything there.
If you come into my house, I am the person who decides whether or not you are trespassing. I can ask you to leave if you do nothing but sit in the corner and rant continuously about laser printer supplies.
By default, everything copyrightable is Copyright The Author, All Rights Reserved. Licenses are just contracts to grant you, the user, certain copy rights (like the right to install it onto your computer or put it on an ftp site).
You can hand out as many of these contracts as you like, they can all be different, and you can change new ones that you hand out, but once you give someone a license to do something with that code, you cannot retract that license unless there was a termination clause in the license.
Free software licenses are kind of unique because they license everyone automatically.
So, say ssh was created and licensed to everyone under the BSD license. SSH Communications Security , the owners of this code, decide they can make money off of ssh, so they release it under a license that suits them. Anyone that had a previously-licensed copy of ssh is still free to do anything they like under the BSD license, including fork it into OpenSSH.
In order to prevent people from using the old code under the old license, you either have to terminate their license (using a termination clause already in the license agreement) or you have to make the old code worthless to them. Usually any progress in this direction is at the expense of your users and is considered evil.:)
If you are the author of foobarbaz, a shareware app for Linux, and you include code from other people's software (other libraries, etc) then you have to respect those licenses (i.e. releasing under GPL would be a bad idea) or reimplement those functions so that you don't need the other libraries. If it's under 10 lines of code, it's fair use to do anything with it (less than 10 lines of code are not copy protected, thus no licenses are needed). If your buddy helped write code for foobarbaz, and there's more than 10 lines, he/she has copyright over his portions and you need to ask permission from him/her first.
This is why the Netscape -> Mozilla transition had to rip out a lot of things like Java and RSA support.
I believe all Linux distributions should adopt and adhere to the FHS 2.0 spec. Nothing irritates me more than seeing tons of X application binaries floating around in/usr/bin.
But according to every interpretation of the FHS I've ever read (except for yours:), that's where they should go. /usr/X11R6 is reserved for the X Window System itself, not X applications:
This hierarchy is reserved for the X Window System, version 11 release 6, and related files.
I don't remember a 1.0 either, but there was definately a 2.1 release, their "Mother's Day" release. After that were the toothpaste releases - 3.0.3, 4.0, 4.1, 4.2, 5.0, 5.1, 5.2, 6.0, 6.1...
Redhat just likes to increase the major number for any random large change (new kernel, libc, etc), fault them for this if you like, but they don't have a habit of skipping numbers.
Pick up the phone, say hello quickly, if noone responds in about 1 second (and the line seems perfectly silent, i.e. no background noise), hang up immediately. If it was a real person, they'll call back right away, but if it was a telemarketer, they won't bother.
BTW I've done this dozens of times and never once have I hung up on a real person accidentally.
Or you could do the opposite and waste as much of their time as possible (if they wanna sell you vinyl siding, don't tell them immediately that you're in an apartment, etc). Depends on your mood.
Someone should whip up a speech-to-text-to-megahal-to-text-to-speech processor for answering sales droid calls. That way at least once a year your machine would be telling a sales droid that "I DO NOT FEAR DEATH AND KILLING".
140G's can be incurred in much less of a drop than you think. It just has to accelerate at 9.8*140 (1372) meters per second squared.
If the object is one meter high, and falls to a concrete floor, if it reaches a full stop in less than 7.14 milliseconds (almost certain if the material is concrete-like) it has exceeded 140G's.
It may be possible exceed those ratings in a drop as short as a few centimeters.
oh, and if people know good rippers/encoders for linux... I haven't ripped anything since I switched over a year and some go, and I've got a lot more stuff to throw on that extra hard drive that used to have windows on it..
Best encoder: gogo, or if you're not on x86, try lame. Best ripper: cdparanoia.
I may be a little bit biased on the frontend market, but as the author of abcde I highly recommend it.:)
Circumfrence of a 3" diameter platter is 3*PI or 9.42"-ish. If this is spinning at 30,000rpm (just for fun:) the outer edge is moving at 282743ish inches per minute. This is a useless unit of measure so let's convert it to feet per second - divide by 12 and then by 60. 392 feet per second.
I don't know off hand how forward motion correlates to centrifugal force, but if it is 1:1, then those bits of metal are attempting to spin off the drive at 392 feet per second, that's 40G's. If the outer portion of the head weighs 1 oz (very much an overestimate) then it has to withstand 40oz of force. 2.5 lbs. Distributed evenly, a piece of aluminum foil could withstand that.:)
Now, if the head arm breaks off (don't laugh, I've seen it:), wedging one side of the platter against the drive casing, the other side of the platter is going to hit the other side of the case with 2.5lbs of force moving at 392 feet per second wedging it against the other side of the casing.
Platters (being flat plates) are stronger in tension than compression, they may not be able to handle what amounts to a well-hit baseball impacting them on-edge if the metal used in the disk run was suspect. It could crumple an extremely brittle platter, leaving it unable to handle any remaining tension forces.
Of course, if all of that energy from moving 2.5 lbs at 392 feet per second was used in crushing the platter, there wouldn't be any left to cause the platter to fly apart and puncture the drive casing.
I'm sure some of the math in that was off by an order of magnitute (I'm really not at all sure about the centrifugal forces involved), but if so, it's off in the direction of safety.
However, if a platter did disintegrate, it would sound really cool..:)
I would be more concerned about the turbofan on your average airliner losing a 3' blade spinning around at 500mph to slice clean through the adjacent hydraulics line causing the plane to catch fire and the pilot to lose control seconds before landing causing it to crash into the airfield.
You don't have to upgrade. Ultra2 Wide will work fine with an UltraWide controller, you're just limited to 40MBytes/sec.
Since you're complaining about buying new scsi controllers, it's safe to assume you aren't planning to buy a drive capable of more than 40MBytes/sec.:)
How many women do you really think would want to have cybersex anyway?
As a lab assistant back in high school, I feel qualified to answer this question.
Not many, but the ones that do you CANNOT tear away from the keyboard. It's just like tearing them away from a steamy romance novel, except that they can pick a romance novel back up, they don't want to walk away from a Sexy French Man(tm)[1].
[1] Apologies to those who've never heard that radio spot.:)
Alright, someone suggested that female characters are quicker, more agile, or have a thinner profile, but is that really true?
In Q3, yes. I'd believe that the target area is the same, but the female characters weigh less, which means they can jump higher, have better mobility in flight, and fly farther when rocket jumping at an inopportune time (f.e. continuing to fly sideways across The Longest Yard until hitting the edge of the level and falling straight down)
Wankel rotary engines aren't that bad. They're 1/4 the size of the equivalent power reciprocal engine, much cheaper to make, a magnitude fewer parts...
You can get 40% efficiency out of a well-built reciprocal engine (40% of the gasoline's explosive energy turned into torque), the other 60% disappears as heat either through the cooling system or through the exhaust. The reason these figures are so good (in comparison!:) is that the heat in a reciprocal engine is concentrated at the top of each cylinder. Less metal to heat up means less fuel wasted heating metal.
Wankel rotary engines top out at around 30%, mostly because the entire crankcase is the cylinder head. They heat much more evenly.
It took the automotive industry 50 years to push 30% to 40% for reciprocal engines - they might be able to do the same for rotary engines given another 50 years.
I believe there are already bugs filed against all of these packages. You can urge the maintainer of the package to fix it by writing him at packagename@packages.debian.org.
What can't I take advantage of my friend's diligent use of apt-get just one IP address over?
Well, right now you can do this: scp friend:/var/cache/apt/archives/*/var/cache/apt/archives
Later, you might wish to have both apt sessions run through an http proxy server (such as squid). For example: export http_proxy=http://friend:3128/
As for the installation questions, non-interactive debconf backends are being worked on, but even that won't be a timesaver for 2 machines. Just answer the questions:)
PCI 2.2 only supports bus speeds of up 264MBytes/sec if your lucky
264MBytes/sec is more than double 1000Mbits/sec.
Just to review: gigabit ethernet = 1000000000 bits per second = 1000mbits/sec = 125mbytes/sec standard pc pci (33mhz 32-bit) = 33333333 transfers per second (+/- 1%ish) * 4 bytes per transfer = 133ish mbytes/sec mac pci (66mhz 32-bit) = 66666666 transfers per second (+/- 1%ish) * 4 bytes per transfer = 266ish mbytes/sec alpha and others' pci (66mhz 64-bit) = 66666666 transfers per second (+/- 1%ish) * 8 bytes per transfer = 533ish mbytes/sec
(I say +/- 1% because the clock chip on the average PC isn't at all accurate - your Celeron 466 might actually be running at 463 or 470mhz.)
Furthermore, you don't have to have a computer that can soak the ethernet to get an improvement in speed out of gigabit ethernet over 100mbit ethernet. You just need a computer that can push the packets out faster than 100mbits/sec.
It seems pretty clear that the average celeron box is capable of this.
Now, you'd think after merging with VA they wouldn't need revenue from the ad banners so they'd just get rid of them or do the "community banner" thing like VA does with linux.com.

Of course, radio telescopes don't have to be arranged in a one-dimensional fashion.
Yeah, but at least you can disable the Netscape Shop button and the Communicator Radio.
Really peeves me that you can't get Navigator > 4.08. Oh well, even if they don't ship Mozilla like we want, it can be pared down easily enough. :)

Debian packages are supposed to depend on a specific packagename *or* the virtual package, for example:
Depends: libc6, exim | mail-transport-agent
If you didn't have a mail-transport-agent installed previously, it will install exim for you.
The authoritative virtual packagename list is h ere, it's updated from time to time.
