Whoops, did my math wrong; forgot days had hours. It's only 871 years of that in a terabyte. (whew! that's better. cancel red alert) -- 2^40 / 40 / 3600 / 24 / 365.25
But with IRC, unless you're making logs, there is nothing 'saved'. There is nothing static about IRC.
This company appears to have had terabytes of data. Lessee:
/me is in the hizzle fo shizzle
is oh, about 40 bytes. Say there's a comment every second of evey day... a terabyte would hold over 20,000 years of such comments. Or 20,000 such IRC channels for a year.
Sure this doesn't account for file trading, dead channels, bots, etc... but it gives you some idea about the amount of data in a terabyte, and if you think there is anything anonymous about IRC, think again...
in fact, this comment will probably be stored somewhere for way too long.
Gentoo on ppc is sweet, that's for sure. Interestingly, on my Mac, OpenOffice on Gentoo runs little circles around OpenOffice on OS-X using the Apple provided X window system. Everything about it is faster - from starting up to saving large spreadsheets - and not just a little faster either. It's the difference between quite useable (on Gentoo) and painful to use (on OS-X)... Mozilla is faster too.
Downside: it takes a week to install.
Wanna know why I keep OS-X around if Gentoo is so much faster than OS-X? My two-year old is addicted to the games at noggin.com, and just try finding a flash player for linux-on-ppc. No really, try. If you find it let me know.
Interesting that you use google's cache as an authoritative reference, when google itself doesn't agree with you.
I'm not saying you are wrong; I'm musing on the fact that Google has become a reference for just about everything, and in this case they appear to be wrong.
I have a Belkin optical wheelmouse plugged into my G4 via the USB keyboard. I know I paid less than US$20 for it retail. It works with no additional drivers exactly as I would expect in OS 10.3 - right button is control-click which typically brings up an options menu, middle button (wheel) pastes in X, and the scrolly wheel works in most everything, even xterm. Left button is the one big button on the original mouse.
Why they choose to ship a one-button mouse even now is beyond me, but they aren't locking you into that mouse forever, and have obviously anticipated more functional aftermarket pointers.
To get this back on topic, if you are looking for a reason to get the Opteron over the G5, the stock mouse is only about a $19 reason.
Mine too. Kogi L4Ax 14-inch LCD, plenty bright, 1024x768 resolution, runs on 12 volts and draws around 14 watts. It's the cheapest LCD I could find earlier this year at just over $200 at the Best Buy.
I suspect that this and one of those mini-itx boards with the Via chip would make a nice basis for a solar-friendly system, but I agree with most other posters so far that a laptop would probably be better.
Oh, and in case anyone reads this post: DO NOT run a laptop off a solar panel without a charge controller!! Open-circuit voltage of a nominally 12-volt panel can be over 21 volts, easily enough to cook any sensitive 12-volt electronics. Somewhere there is a photo of me and my new 40 watt BP panel and my about-to-be-fried laptop, because I just couldn't wait. Yes, I knew better, but I had a new panel! and a 12-volt load! At least I only gave $50 for the laptop.
Since you clearly own the right to listen to this song, I'd be happy to email it to you, since I own the right to listen to it also. However, I think there was a decision against mp3.com that established that I don't have the right to share with you, even if we both own the rights to the song...
But being the social creature that I am, I'll do it anyway. I was taught to share in school and I've not been completely brainwashed since then. You can reach me via email at the disposable email address crash.from.rebar@spamgourmet.com. 160Kbit vbr mp3 OK?
Hi. For what it's worth, I benchmarked Oracle single-system (16 cpu) vs. Teradata (4 node by 4 cpu) for a database system of about 5TB total -- the benchmark was about 1/10th that size. While Teradata has an interesting aproach, Oracle *blew it away* in performance on the same queries, when properly tuned. However, when IMproperly tuned, Oracle *sucked pond water* by comparison.
Part of the reason Oracle was faster on our benchmark is that Oracle's parallel hash joins are very very fast, and part of the reason is that NCR wasn't keeping up with the latest Intel CPUs - I believe the machine I benchmarked had 700Mhz Pentiums (two years ago) and I suspect they bogged down on the computations.
Disclaimers: (1) YMMV, this was with my workload; I can imagine a workload in which Teradata would win. (2) When the Oracle optimizer makes the wrong decision, it REALLY sucks, as in kill-this-it-aint-never-gonna-finish. When Teradata had the wrong notion about a query, it maybe ran twice as long as when it was working optimally. Maybe that's why it seems faster to users; there are fewer instances of it just going to shit because the optimizer decided nested-loop-full-table-scans made sense.

In Little Rock, there is a fish restaurant with an entire wall of them. I looked for a picture online to no avail... they will give you a free fish dinner in trade for your Billy Bass. Some of them have been painted up rather creatively too.
Lessee: videoconference toy or free fish dinner. I'd take the dinner.
I can see Agent Gates saying: "Tell me Neo, what good is UNIX when you cannot SPEAK to it?" and proceeding to gum up the Windows telnet client to the point of unworkability.
Your icemaker may be stuck. No, really. Mine broke exactly at that point in the cycle where it heats the ice tray to melt the cubes just enough to slide them out. It was sitting there in my freezer, warming itself all the time. I figure it was costing at least $20/month.
Using your example to answer one of the questions of the poster: Electricy where I live costs $0.08 per KiloWatt/hour.
Your extra 50 watts is (50/1000*24) 1.2 KW/h per day, times 31 days is 37.2KW/h per longest month, times $0.08 (for me) is $2.98 per month. Plug in your electric rate for your cost.
If you have to move the extra heat produced, your costs will go down in the winter and up in the summer.
Sound without perception is just waves in the air. If a person drops $10K on speaker wires, the music will very likely sound better to him, even if there is no measurable difference in the signal reaching the speakers. Just because it's called the placebo effect doesn't mean that the results, which is the betterment of perceived sound waves, aren't real.
If I have a headache, and someone sells me a sugar pill but I believe it is a powerful pain reliever, my headache is more likely to go away and I will be pleased as a result. Similarly, if someone sells me $10K speaker wires and I believe they have a powerful effect on my stereo system, I am likely to perceive the effect and may even think the improvement is worth $10K. The trick is making me believe it, and that is where all the "oxygen free" and other techy sounding things come into play.
At least, this is what I like to think is happening. It is the only explanation I can come up with for this. If spending $300 on a box with a single LED allows a person to more fully enjoy his sound system, is there anything wrong with selling it to him? If you hear the difference it may be worth it to you.
I've noticed that Audiophiles don't like it when I call them ignorant saps however.
Maybe they listened to you and changed the web back-end already, or maybe there isn't a hard date. I just successfully ordered it for my Powerbook purchased on Oct. 3. It saves them some money; I was ready to box it up and take it back to CompUSA.
Even though the form that is linked from the parent post says that you qualify if you purchased on or after Oct 8, I clicked through, entered Oct 3 and my Mac's serial number, and it allowed me to order. Woot!
Moral: If you miss an arbitrary deadline, try anyway.
Lessee: I don't know where you are, but lets say your electricity costs somewhere around $0.12/KWh, which I believe is a little more than average in the US. That's 833 KW/h you are using in a month, or an average of 1.14 KW all the time. Them's some laptops you got there.
Okay, assuming you get an average of 4 good hours of sun a day (which is pretty typical), you would need about 7KW worth of solar panels, plus enough battery storage for some days without sun, plus a nice inverter, and not counting losses due to different charge voltage than your panel's optimum specs, and also inverter and line losses. Panels today will run you maybe $3.29 per watt. Before installation, batteries and inverter, that's $23,030 to save $100 per month.
Point: Do it for yourself, do it because you want to learn, or cut coal emissions, or because it is the enviro-geek-cool thing to do, or because you love the notion of being independent of the grid or living with a lighter footprint on the Earth. But don't do it to save money.
Getting back on topic re: the article, I'll believe it when I can buy it. I've been hearing about sub-$1-watt solar for years and years.
Unfortunately, if you want to run Oracle, you are stuck with RedHat Advanced Server or United Linux. Of course if you are buying Oracle you can afford RedHat AS also, and up2date isn't bad, but I would certainly prefer Debian.
Knoppix, everyone's favorite Debian-based live Linux CD, has an easy script to install to a hard drive partition. This is truly nice for anyone wanting a mostly pre-configured Linux installed with lots of nice toys like Mozilla and OpenOffice.org AND that has all the juicy apt-goodness of Debian as well.
Only accept emails from people who include in the subject line (or an X-Verification in the header or something) a link to an OPTION to charge the SENDER for the email, for something like $0.10. You can bet that those people who choose to collect, I will not continue sending emails unless it is really important. People who send me mails that are my friends will not be charged (because it is an option to charge by the recipient), but you can bet I'd be clicking the charge button for every mortgage or member enlargement offer that I receive. I may even ding that coworker who thinks I enjoy receiving email updates of everything he finds interesting on the 'net.
Of course, the devil is in the details; securely implementing this concept is left as an exercise for the reader.
I don't know if there are tools to do this on Linux or not, but the ability to effectively add and remove raidsets to filesystems on the fly, and have the filesystem recognize that it just got larger or smaller while mounted and files are open, is very nice indeed. This is possible using the advfs tools on Tru64 at least; maybe others. What is *really cool* is that if a file is on a disk that you are removing, the OS will move that file to another disk in the domain on the fly, even if it is open! To me, this is truly powerful.
No debate on the merits of commercial UNIX vs. Linux would be complete however if someone doesn't mention the kick-ass software RAID driver "md" that Linux has. Does any other UNIX have software raid that is this complete? I would certainly consider this a "high-end" feature.
1.) Kernel Patch Forever 2.) The Hunt for Related Libraries (apt-get is considered cheating) 3.) Theme Manager 4.) Recompile the Compiler - a traditional UNIX strategy game
It beats playing Windows-based games like Reboot-after-simple-install which I also find myself playing pretty often.
And don't you mention ATA RAID. Those who do never used real SCSI Raid (as in "Enterprise" RAID;), or just plain lie.
Er, no. I've used both, and I am not lying.
One can cost an order of magnitude less than the other, and still performs reasonably well for small servers.
I'm talking about hardware ATA RAID, not that promise or highpoint software raid.
I just tested one hardware ATA RAID-1+0 set - 75MB/sec writes, 81MB/sec reads, 640GB online.
I'll grant you this: the performance of "enterprise class" hardware SCSI raid may exceed this, unless you go fibre channel which will definitely exceed this. You may be more concerned with latency than bandwidth, in which case the faster rotational speeds of SCSI drives may be somewhat better for you (thus the point of the original post).
And generally, you can cram more SCSI cards in an enterprise class server than ATA cards in a PC.
However, when looking at $50,000 storage solution vs. a $5,000 storage solution with similar reliability and performance for a particular business problem, which would you choose, if you are aren't spending someone else's money?
There is some interesting info at the bottom of
this page outlining some improvements Oracle and RedHat have made to this linux kernel regarding things such as SMP processor affinity and asynchronous I/O. Presumably these are open source changes -- the artical doesn't mention them at all.
