I just want a true black. I bought a 30 inch LCD panel this weekend only to find that the black levels were so horrible that the screen was almost unusable. Looked good under the store lighting, though...
Absoluely. There's also a feature in the latest firmware that allows the 60CS to take barometric pressure readings even when powered off. It eats a little battery, but keeps the unit accurate over the long haul by compensating for atmospheric changes.
The auto-callibration on the 60CS using GPS data ain't that great. I callibrated mine at the local private airport (accurate data for both altitude and barometric pressure,) drove to my house a few miles away, and set the GPSr in the window. Everything was good for a few days, with only very small variations in altitude. But when the next storm front moved in, it was all over. Afterwards the recorded altitude varied by 100 feet or more over the next day. I then callibrated it again at the airport and all was well.
Not if the guy who placed the cache was off by a mile with his GPSr
Always a pain. On the rare occasions when I get a WAAS signal and am accurate down to less than 10 feet (sometimes a lot better) I often still find myself off by 40 feet or more because someone either can't read or had a POS GPSr. But nobody would do it if it were too easy, so...
"Cybersecurity consultant" huh? The only people I know of that use that title are PHBs looking for catchphrases on resumes, jackasses with A+ certifications that read a book on security once, my boss, and Kevin Mitnick. And I wouldn't let ANY of those people anywhere near a secure system unless they were menacing me with some kind of weapon that I was sure would actually work.

The CERC controllers are good for the low end, though we've had problems with the IDE (a modified LSI Logic card) version under linux, mostly due to the megaraid vs. megaraid2 drivers (hint: megaraid2 has a memory leak with the IDE CERC cards!)
The new SATA CERC card works pretty well in my limited testing (just got one the other day) but it seems to work extremely well with Fedora Core 2. Looks like it requires libata, but it also uses the aacraid driver. It's a remarked Adaptec card.
The high-end PERC cards are fantastic. No caveats like the CERCs described above... they're flawless in my experience. The only thing that could be remotely described as a problem occurred back in the RH 7.2 days; the 7.2 load media didn't have PCI information for the newer PERC cards, so it had to be supplied manually at boot. After that... everything worked fine.
Short version : If you're going to buy a CERC, buy the native (LSI Logic or Adaptec) versions and save yourself some money. For the PERCs... they're good, but so are many of the off-the-shelf cards out there. The integration of the PERC is excellent, however, and Dell's support is fantastic, so if that's important to you...
I've been told I'm a bit obsessive about home backups, but...
1. Four disk RAID 5 on Fileserver A (hardware controller) 2. Monthly full backup to disk on server B. SKip non critical that can be replaced (mp3, movies, etc.,)
a. Immediate encrypted copy of critical data to DVD media and store in fireproof safe.
b. Immediately encrpyt a copy and send to another system offsite via portable HDD. 3. Weekly backups of everything that has changed since the last full or weekly backup to disk on server B. Save to encrypted DVD and put in safe whenever a 4.7 gig chunk is created. 4. Daily incremental backup of all changed data since previous backup of any level to disk on server B. Save to encrypted DVD and put in safe whenever a 4.7 gig chunk is created. 5. Weekly mirror (via rsync) of entire data filesystem to encrypted fs on USB hard drive. Dump root/boot/var/other system partitions via dumpe2fs to the same encrypted fs. 6. Daily copy of super-critical data to an encrypted USB keychain that I carry with me when I leave the house. 7. Encrypted copy of data from step 6 to a second offsite location. 8. Encrypted hourly database backups to both offsite locations. 9. Files in one specific folder are checked every ten minutes for changes. Any file changed in the last ten minutes are copied with timestamp value to a separate folder. Anything in that folder older than 48 hours is erased. (This is because MS word keeps eating one really big document and corrupting the on-disk version.) 10. Desktops backed up to server B as above and stored as above.

Don't forget the superbowl effect... this commercial took down a site far faster than the wettest of slashdot's hypertext induced dreams. I hit the URL seconds after it showed up during the superbowl anti-tobacco ad. Thirty seconds later, it was reduced to a molten ruin that hasn't been seen since slashdot reported Linus had birthed Daryl McBride's love child. It was epic. So don't give me your slashdot effect or google effect. I bring you he SuperBowl effect.

I think the poster was referring to the contrails BEHIND the missiles. In a vacuum, the gasses of the contrails would disperse so quickly that contrails that long would be unlikely if not impossible. They'd disperse to invisibility just behind the motor.
One important note regarding sysprep; don't sysprep a machine more than once. If you do, you'll likely not be able to boot a second time. As a result, we've always kept two images of each production load; one before sysprep and one after. That way, we can return to the non syspreped image if we need to make changes and still be able to run sysprep.
While SCO's antics are often confusing and sometimes amusing, this is not a matter that should be taken lightly. Too many people are taking this lightly, and I have a fear that at the end of the day, the OSS community is going to be caught bent over with their pants down looking back on a grinning SCO.
The court system in the US is less than predictable, and often makes ludicrous decisions in favor of seemingly frivolous lawsuits (see RJR Reynolds, McDonalds, and KB Toys.) Linux CAN lose, and defeat in just this one battle would be disasterous.
And what does SCO have to lose? They admit that they only have a few hundred customers, and it would be no big loss to the world for the company to disappear. SCO execs have already made their money, so defeat wouldn't harm them much, even if it meant the end of their corporation.
Linux, on the other hand, would be utterly destroyed. Invalidation of the GPL would mean that existing GPL'd software could be incorporated into commercial code without restriction or credit to the original author. Commercial vendors would be at SCO's mercy, and many would be forced to fold. Non-commercial linux developers without funds to support a lawsuit would be forced to fold. Linux, at least in the US, would be dead.
Be amused, but those that are in a position to make a difference need to take this VERY seriously, or risk a serious blow to Linux' very existance.
Helloooo... IBM, are you listening??? Wait, wasn't HP the supposed Fourtune 500 company that bought a SCO license?
And you may have just hit the nail right on the head. If HP owns a valid SCO license, and it requires that its customers run an HP provided version of Linux on HP hardware, they may be covered by the license that they own... their customers may already be running a licensed version. So win or lose, HP's customers are covered.
We have an incident response team that locates each individual infected host, then identifies the primary user of that machine. If they're unavailable, we install the patch and leave a message that they should come by our offices as soon as possible.
Once the patch has been applied, we sit down with the user and assure them that they're not in trouble; everyone makes a mistake from time to time, and we have simple and effective means of dealing with the problem. Once they're calmed down and convinced that we're not upset with them, we wish them a good day and send them on their way.
When they turn their backs, we shoot them in the back of the head and put their bodies on display in the courtyard as an example to the rest of the imbiciles that might practice unsafe computing.
Incidentally, I finally decided to simply put the servers in the basement in a small room with a vent fan and an exposed concrete wall. The concrete should keep the air a little bit cooler. If not, at least the fan will keep the room at a temperature constant with the rest of the basement. No water cooling, no phase change coolers. Just good old fashioned air.
Now that's just damn creepy... I was thinking about doing something very similar just yesterday. I'll be building a house soon, and was thinking about what I'd do if I could build a cooling system directly into the house. The idea I came up with is similar to this one, but I think I have some improvements.
The garage floor is at ground level, and concrete is an AWFUL conductor of heat. This presents two points of inefficiency; the temperature of the concrete will be affected by seasonal temperatures due to air temperature and proximity to heated surface earth along the edges. Depending on what part of the country you're in, the ground temperature below 24-36 inches is a constant temperature in the low sixties or upper fifties. SO, while the base of the garage floor's foundation is likely below this point of constant temperature, the poor conductivity of the concrete will likely render the system far less efficient than it could have been.
My server closet would be in the basement, preferably with the systems close to the ground. The system I envisioned is identical to his up until the heat exchanger. Rather than dumping heat straight to the concrete floor, I thought of getting a 18" x 18" steel plate and welding 1" thick, 24" long iron bars to it, perpendicular to the surface of the plate. 16 bars should do. You then sink the bars through holes in the wall straigt into the earth as close to the floor as possible, resulting in the deepest possible depth for the bars. Your heat is then dumped to the very cold, constantly cooled earth at a depth of anywhere from four to five feet.
On a practicality scale of 0 to 10, 10 being as practical as brushing your teeth and 0 being as practical as replacing your teeth with screw-on ceramic chompers that you can toss in the dishwasher, I give this solution about a two. Nobody in their right mind is going to go to all of that trouble to cool a few CPUs. Or drill holes in their foundation, for that matter. But it would still be cool.;)
Thats from sattellites being so far up they still are reflecting the sun and our atmosphere either squashes and/or stretches or even reflects it multiple times.
I just can't get the image of Will Smith saying "Uh, some swamp gas reflected off of venus, and uh..." out of my mind.
