There used to be 1 and 2 dollar notes, with the existing 5/10/20/50 cent coins. These were replaced with the "gold" 1 and two dollar coins, at around the same decade as the 1 and 2 cent coins (which were brown), were phased out.
15c/kwh is normal here. (Australian Dollars). But even if it was 1 cent.... Why waste it? Some peoples annual incomes are reasonably measured in cents. Solar power (and other 100% green technologies), are still expensive to get in large quantities. If you can run 5 pcs off 100 watts, instead of one, that can be useful if your off grid. (perhaps you should be;-)
Warmer air can carry more water right? So the air inside the data centre would be extremely dry. Most computer equipment specifies 0-x% humidity. So lowering it doesn't adversely effect the equipment. I'm sure the outside environment doesn't care either.
Hmm, I have a PDA running "GPE" that allows me to transport an X app from the PDA to another location..... I'm pretty sure the tray "applet" that does this is only automating a process you could complete manually.
Whats going to survive? Your mythtv backend recording your tv show, FTP transfers... who knows what else your running.
If you use a VNC layer in there, like I do, the local X can die, and your apps are still running. Plus you can log in from elsewhere at will.
If you really don't trust your drivers, go look at superunpriveleged.org, and have a look into microkernels, such that you can restart your filesystem drivers etc. without being "F'ed"
I believe I am feeding a troll here...... However using that tool cannot give you an apples to apples comparison of windows to any other OS. Your photo evidence shows a score for "Registry Permissions".... This is therefore a weighted mark, because some OS's do not include a registry, and thus cannot be scored on this basis.
It seems it is scored on "Best practice" (that wording is from their site). Part of the point of hacking exploits is that "best practice" is a constantly moving target as holes are discovered and patched. Each hole moves best practice away from being secure, and patches move best practice further forward.
There are guidelines for writing secure systems, but they are only guidelines, not guarantees, yet they are "Best Practice".
This sort of test, can *only* score known vulnerabilities. The problem with security is the unknown vulnerabilities. Even if you have addressed 100% of known vulnerabilities, it only takes 1 to get cracked.
I hate to use an analogy, but the way I see Tivo's locking down of the hardware to "blessed" versions of the software, seems to be preventing you from doing what you want with it. I'm thinking along the lines of how annoyed I'd be if I put a new stereo in my car, and then it refused to start up.
I call bs at this scentence:"Baker had not been told about a tenfold boost in microwave power planned that night to handle the anticipated increase in holiday long-distance calling traffic". Boosting power won't increase bandwidth, it'll increase transmission distance....
and works wonderfully in windows, after you install the drivers? I haven't installed a windows system yet that didn't run at a suck hole resolution until better drivers were installed. However I will say it has been a while since I installed a windows system.
This is something we really should be able to do in open source land... Since the drivers are nearly always in the kernel, we should be able to drive LCDs at native res out of the box. In windows land you usually have to download the drivers first...
I'm not sure how you guys managed to make your roads so dangerous.... I believe that in many places you can ride a bicycle on the road, and the smart car should be safer. I don't like the look of them, but I've stopped buying cars for looks.
I tend to talk to Taxi drivers about their odometers.... Generally whenever there is an impressive amount on the odometer, it is not all original drive train.
doesn't AC Nielsen do this? As in they create "ratings" to inform broadcasters/advertisers what people are watching? Sure it's aggregate, maybe your interested in what a perticular person is watching?
You would effectively be running 2 raid 5 stacks (with one partition on each drive for each stack). Then you could use LVM to combine them into one larger volume, with normal raid5 redundancy.
Is that thr probability of two drives failing at the same instant? Because you can set it up to down the system when the first failure occurs, and you start it up with the new drive....
Or you can use raid6 so you can lose more than one drive.... I'm not sure if the number of parity drives are configurable or if it has to be 2.
If it's like me, and it's for storing media, the backups are the original DVDs, and CDS. It's more of a pain in the ass to back a terabyte up somewhere, then to risk resizing the array without backups, and re-rip. Of course the reason for the RAID is to prevent having to re-rip if a drive fails. It's more about convenience than anything.
I think the comment about CPU performance was more about the fact that with faster CPUs, the speed benefit of a hardware raid solution isn't as useful. I checked the raid6 personality on my 1Ghz celeron, and it reports that it can calculate RAID parity at a throughput of 985MB/s, using the SSE parity calculation routines. That's more than you do any useful file serving with (it has to go out on the network, and that'll saturate gigabit ethernet). The I/O performance advantage of a hardware controller doesn't seem too useful here.
I'm also not sure why software raid can't benefit from the multi-channel read performance available with raid 1, 5, etc.... Why can't the software issue a read command to two drives simultaneously?
The comment about a buggy raid controller obviously wasn't talking about a new controller, but one that has eventually failed. I imagine they generally become obeselete before they fail, but even so, a failed controller really sucks if you need to figure out how to get the raid stack running on another controller. I had a quick look into it at one stage, and it broke my brain trying to work out what controllers worked with what....

I think servers are probably much more important than desktops in terms of power savings, just because they are on far more of the time....

Yes, indeed, you should have asked for the installation disc, unless you really wanted a hard drive, or floppies.
They draw serious power, but they also have some of the most power efficient data centres going.... Lots of bang per watt from google.

Oh anonymous coward, how full of wisdom you continue to be. Linux actually runs usably on all my hardware, which windows does not.
I agree... Hell, I'll take 12Mbps wireless if it's going!
Also not for the status quo, so more likely to be a liberal than a conservative, depending on your definitions.

zfs or fossil. I think there is a fuse driver for zfs on linux.

RAID6 for the win! Fail one disk, and while it's rebuilding, you still have enough redundancy to lose another one!
