SCO stockholders (like Darl) win by propping up the stock prices so they can make money from speculators - there is a very large upside if SCO were to "win the lottery" and get a judgement against IBM.
But the real winners - no matter what the outcome of the case - are Microsoft and SUN, who stand to gain whenever they can spread Fear, Uncertainty, and Doubt about Linux.
Microsoft surely didn't expect SCO to win. But MS supported the lawsuit with money anyway, since it hurts Linux in the business world. Microsoft doesn't care if SCO goes down the drain in the process. The money spent is a pittance to Bill Gates. The return on investment is huge. The downside is practically nonexistent.
Bill Gates is still the best marketer around. Never forget that.
A security expert was lecturing a room full of sysadmins, myself included. He asked us two interesting questions.
"Raise your hand if you have been hacked."
A few sheepish looks from 20% of the attendees who raised their hands, knowing smiles from the rest.
"All right, raise your hand if you DON'T KNOW you have been hacked."
Everyone laughed, because they understood that detection is not 100% reliable. Even crusty BOFH admins can get hoodwinked. It's just easier to hack, and get away with it, when the mark isn't security conscious.
Wow. The pilot episode of Star Trek dealt with this subject. As The Keeper points out, "Your race would soon discover our powers of illusion and destroy itself too."
Many people would do nothing but re-live the experiences that were stored in the thought database. Scary technology.
Perhaps 0.23 was the answer to a homework problem, or an example in the texbook. Most of my classmates didn't bother reading the textbook before the lecture, which is a shame. Peter Parker, being an astute student, has naturally read ahead of where the class is.
I wish to put my old vortex card into a Linux box in order to get hardware sound mixing, can you tell me the best place to get the drivers from? Sourcefourge?
The usage of the entire HF spectrum (3-30 Mhz) for BPL is an abomination. There will be tens of thousands of 10 watt broadband transmitters hooked up to what are essentially longwire antennas, which will effectively destroy EVERYONE's ability to use this precious and shared resource. On HF I routinely make contact with people on other continents who are using 10 to 100 watts, using antennas shorter than any BPL segment. Even in places that make BPL illegal, there will be huge problems for anyone who uses the HF spectrum, since the ionosphere will allow the crud to propagate worldwide.
A "no urinating" section in the community swimming pool won't protect you from the kids on the other end of the pool. BPL is pissing on all other users of the spectrum, big time.
At long range, the electric fields of a closely-spaced pair of oppositely-charged particles will cancel, if the charges are similar in magnitude. I think this effect is what Lucas had in mind.

There's a new version out as of May 10. According to the changelog the problematic SCSI drivers have been removed from the normal boot sequence.
* V3.4-2004-05-10 (small updates) - removed some scsi modules from the regular knoppix26 (Kernel 2.6) startup
because they are unstable. Use "expert26" to load them. - Added script for generating bootfloppies in Knoppix "Utilities" menu - Harddisk installer update from Fabian Franz - "knoppix splash" fixes - timezone and language setting add-ons - added linlinc1 for captive-ntfs for download capabilities - changed some e100/eepro100 network driver entries in hardware detection - the usual debian package updates
If you are going to game online while running some torrents in the background, it still pays to have your bittorrent software limit the upload speed so your game has some 'guaranteed' outgoing bandwidth. Otherwise, you will experience noticeably worse lag spikes in your game. (It's easier to merge on a freeway that's running below maximum capacity.)
To take your idea a step further, there could be a database of domains that many people have decided are spammish, that you could automatically reject from your search results. Of course, just like the email version of such databases, it would be possible to game this system as well. That would mean more admins, and possibly more legal expenses. But I, for one, would welcome this feature.
Perhaps Google could team up with some larger ISPs, and give negative rankings to spamvertised websites and domains.
kyhwana is right - you need to throttle your BT upload speed so that there's room for the acknowledgement packets you are sending to people you are downloading from. On my ADSL connection I have 1.5Mbps down and 256kbps up, so my uplink is theoretically able to handle 256/8 = 32 kbytes/sec, ignoring protocol overhead. I am using the wondershaper script on my firewall, so that gets eroded to 220kbps or about 27 kbytes/sec max throughput.
On a fast torrent I hit my max download speed (120 to 140 kbytes/sec) which uses about 6-8 kbytes/sec of my upload bandwidth for ACKs. So I can run up to 19 kbytes/sec uploading before I see congestion and slowdowns. I usually throttle it back to 15 kbytes/sec to maximize my downloading while allowing me to do other things online while BT is active. BT is set to allow a 10:1 ratio for your download speeds from other leechers. So, if you are uploading at 15 kbytes/sec, you should be able to download at 150 kbytes/sec. If you are downloading from a seed, then the ratio doesn't matter:-).
If I am only seeding, I can just let BT use the maximum uplink speed of my connection, since there isn't anything else downloading. The wondershaper script on my firewall is set up to give low priority to BT packets. Activity on my other machines will get placed at the front of the queue, if there is a queue. The price I pay for low latency for ssh, web browsing, email, and gmaing is the loss of about 15% of my max bandwidth. It's a worthwhile tradeoff.
"Something that is accepted as the truth without proof."
School is all about dogma. "Swallow this and then regurgitate it at exam time."
The merchants of cool (do what we say, it's cool) are all about dogma. Of course they will try to use it to modify our behavior, it usually works quite well.
It's ironic that teachers/schools routinely push "fair use" to the breaking point. So, will the kids listen to the short-lived spew from MPAA, or will they learn by watching their teacher's example?
"Should BayStar be working for anti-OSS clients (which it is), SCOG's litigation failure and demise is of no concern. It's a cost of doing business in the effort to make OSS untouchable to corporate America."
This should be modded +5 insightful, and I just used my last mod point. Dang.
Going back to the Chess analogy, sometimes you need to sacrifice a minor piece for the good of the King (Microsoft.)

One of my fondest memories of a final exam is a physics problem dealing with the acceleration needed for Superman to catch a baby that fell off of a skyscraper, and what acceleration was needed to slow to 0 velocity as they both reached the ground.
I was seeing the Bit Torrent client on one machine accepting incoming connection packets that were addressed to ANOTHER machine on the same subnet. That's weird. BT must be setting the network card to "promiscuous" mode.

Oops, I had the decimal place wrong, it isn't 625, it's 6.25 Gbps. Must be time to clean my glasses!
And yes, even then, the hard drive only can write at a fraction of that speed.
I wonder if the technology exists for switching at that rate? Stuffing bits into one end and pulling them out at the other is much simpler than having to examine headers (or god forbid, the payload as well) before sending a packet to the correct interface.

"gawd, I hate their use of "patriot" that way, does anybody know the etymology of the word "patriot" with respect to this legislation?"
1) You pronounced "God" with only one syllable, you must be a pagan or something. (That's a joke, son.)
2) The practice of "NewSpeak" is an old one. Only someone unpatriotic would vote against something called "The Patriot Act", right?
I can't help but feel that the movie "Brazil" was correct about our near future.
Well, if some Arab nutcase decided to attack Jewish people with this technology, he'd also kill most of the Arabs - they are the same genetically.
