The bottleneck is the design of the mechanical disk. You can minimize the bottlerneck by having more disk spindles handle the I/O.
As you've found out it does matter which RAID scheme you use. RAID 0+1 will outperform RAID 5 substantially.
Think spindles. Because each disk has only one spindle, the disk head can only be over one given track at any instant. If you want the heads to nearer to your where your data is stored you want to have more heads. With RAID 1 your read or write request can be handled by more than one disk spindle. That gives you the best performance.
To get more spindles, use as many disks as practical. I've had some long conversations with my co-workers that now that disks are really cheap it doesn't matter that RAID 1 "wastes" half the disks. It does matter that disk I/O is a bottleneck and more disks will help ease that bottleneck..
References:
"In general, when cost is no object, RAID 1 or RAID 0/1 provides the best overall performance. Since striping spreads the I/O load across multiple disks, RAID 0/1 has the best overall performance characteristics of any RAID option. However, if you know ahead of time that the proportion of writes to disk is low, you can fall back on a less expensive RAID 5 configuration. In addition, if there is adequate battery-backed cache memory in the configuration, you may be able to support a moderate amount of disk writes under RAID 5. But even with large amounts of cache, a heavy write-oriented workload is likely to cause performance problems under RAID 5."

Add more physical drives to the current arrays. This helps to boost both read and write access times. But don't add more drives to the array than your I/O controller can support.

A noticed the black blobs on new sidewalks right here in Chicago. I could see a lot of dots on the sidewalk below when I looked down from the 'L' platform. I figured that they were chewing gum but wondered how there could be so much.
It makes sense that it's tar that flows off of the roofs in the extreme heat. I saw a temperature of 106 degrees F on concrete a few weeks ago. Black flat roofs probably get a lot hotter.
Reminds me a great deal of the stories about John Glenn's "mission" on the space shuttle, and all the "science" they would gather from sending an older man into space.
Following John Glenn's successful orbital flight, he was deemed by NASA to be a "national treasure" too valuable to risk on later flights. Sorry buddy - no moon ride for you. Which was a bit of a nasty way to repay all that training and risk. The shuttle flight was an attempt to make up for how they treated him in the 60s.
But NASA let Alan Shepard connive his way into a walk on the moon. All he did take the first manned ride into space on a U.S. rocket.
John Glenn was hailed as great hero at the time. but I think a lot of that was the due to the great P.R. asset that was "Mr. Clean Marine."
See/read "The Right Stuff" for the story. One thing that's in the book but subtle in the movie was that Glenn was a shoo-in to make the frist ride. Then NASA let the astronauts themselves vote. They resented "Mr. Clean" so they voted for Al.
I'll bet they would have liked to have one of these on "Survivor," "Six Days, Seven Nights," or "Gilligan's Island."
Now if they just would come up with a portable cell tower...
Seriously, on the chance that in an emergency I would be near enough to civiliazation to use a cell phone, I'd put one of these in the survival kit in my plane. I have a long-shelf-life disposable battery for my Nokia in there now.
Perhaps that should be obvious to an experienced sysadmin, but most installers of Windows 2000 won't have a clue about such precautions. The intelligent thing for Microsoft to have done is not had IIS turned on by default. This is especially obvious when you consider how many of the Code Red hits you get come from people who obviously don't even use the IIS that's running on their box.
Well, I don't think anybody has to defend NON-professional sysadmins. If you really believe that any Internet server should be so brain-dead simple that you can't hurt yourself you should get what you deserve - even if you managed to pass the MCSE exams.
Since Microsoft is aiming their software at clueless users who can't be bothered to secure their machines, Microsoft needs to ensure that their software is secure out of the box.
Far be it for anybody to defend Microsoft on slashdot but this is an impossible requirement that no other OS vendor delivers - Not other Unices - Not even Linux.
Fifteen years ago we knew that Sun insisted on shipping SunOS with a "+" in/etc/hosts.equiv which would open your system to any other server on the network. We edited that and other config files before a Sun went on the LAN.
In the real world you have a checklist of things that must be done and things that must be changed before the box can put into production especially on the the big bad Internet. In our company, where the NT operations MCSE staff are not exactly the brightest thinkers, we have a standard Windows 2000 build document that has a security checklist and says to only install IIS if the box is going to be a web server. There ARE checkboxes in the custom install where you can deselect the install of IIS and other unneeded programs.
If you dare to draw a paycheck you SHOULD be a Professional. It's up to you to learn how a professional operates.
One week after the outbreak was supposed to be over, I tried setting up a Windows 2000 Server. IIS was enabled by default, and thinking the worse was over, didn't turn it off. I was infected before I could download antivirus software or the patch. This was on a dual T3. Explain to me how this is my fault.
OK, I will.
Did it occur to you that maybe you should connect the box to the Internet as the LAST STEP? - AFTER the server is configured and PATCHED?
You can get the service pack on another system and write it to CD so you don't need an ethernet connection to make the system current with patches.
Plug the ethernet cable into the server as the dead LAST step.
something I noticed from reading it is that it's not patented in satellite broadcasts. Hey, lets all use satellite internet! Or maybe DirecTV, etc. actually uses jpg for transmitting video?
I keep seeing this sentiment posted, and for the life of me I don't know why. Wal-Mart doesn't buy anything directly from Microsoft. It's the manufacturers who have agreements with Microsoft. Wal-Mart and Microsoft have absolutely nothing to negotiate. There is no direct relationship between Microsoft and Wal-Mart, whatsoever.
You ever notice that the name brand consumer electronics at Wal-Mart and Sams Club have model numbers that you don't see at any other store? You know why that is? Wal-Mart gets a special price. The manufacturers have to answer to other dealers so Wal-Mart gets models that won't compare directly to the ones that other retailers have. Really, only the model numbers are different.
Those PCs are made by a outside manufacturer. Have you ever heard of that brand being sold anywhere else? How much do you want to bet that ALL of the PCs with that name are sold at Wal-Mart and Sams Club? Then what do think happens when the maker tells WAl-Mart that it costs ~$100 retail, with no further discount, to pay for the Microsoft products bundled with the PC? That amounts to Microsoft getting nearly 25% of the ~$400 retail price.
The call from Wal-Mart goes to where the problem is: Redmond.
Microsoft. Wal-Mart's just sending a message Microsoft. The ol' boys in Bentonville like to wield Wal-Mart's buying power to negotiate great exclusive pricing deals with vendors. You can be sure that, Microsoft, being a monopoly does not feel a strong need to negotiate. MSFT's monopoly is more solid than WMTs.
So... The Wal-Mart boys think, "We'll show them. We'll WILL feature the product of the competion until they come the table."
So Wal-Mart makes all kinds of noise about featuring Linux on PCs. The aren't serious about it because they know their Joe Six-Pack customer isn't gonna grok Linux, but they hope that maybe the shoutin' will embarrass them and bring Microsoft back with a sweeter deal.
If Microsoft gives Wal-Mart an exclusive price on bundling Windows the Linux PCs will disappear from Wal-Mart's shelves.
I've talked several buddies through disabling the AOL installed "Compuserve WAN Device" whatever that is. It prevents a lot of SMB network services like file and printer sharing, from working in Windows NT/2000/XP. It seems to re-enable itself occassionally.
Network Wizards, the first site that kept Internet census numbers, had a product called the WizTemp that connected to an RS-232 port on a *nux machine. I used a bunch of them on a Sun/Solaris. It was a thermistor in mini-phone plug that plugged directly into a RS-232 connector. It included a script that would monitor the temperature and log it and take actual- send an email - on high temperatures.
Alas, the site site says the WizTemp product is no longer available, but you may want to email him to get the details on what he used and how it worked.
Reminds me of my last job when we fired someone from finance. I had to go confescate his PC, and every "storage medium" I could find from his office while he was in HR. Not quite the same, but he went on the "death march" and his machine just "vanished" from his office.
I had a similar assignment once with more drama for entertainment. The boss told me that he was firing the worthless consultant. Could I do something to keep him from being able to destroy the work he's done so far?
When the consultant got called into the boss's office I went into the lab and REMOVED ALL OF THE KEYBOARDS.
As he's told he's being canned he freaked and stormed out of the office with "THIS IS WAR!" He tore into the lab, positoned himself in front of the machines, and prepared to cause havoc. Then he realized that something was missing and that it was really difficult to carry out his vengeance on any computer without having a keyboard to do it.
He sheepishly sulked back into the boss's office and tried to negotiate. The boss didn't give in. The drama may have reinforced his position.
When I think about it it, that boss wasn't one of the smarter ones I've had but he played this one pretty well. He was smart enough to think ahead and tip me off.
I had gone to him to to tell him the consultant was worthless a few days before.
The only thing to consider is where to get the monitor from, since it is so heavy, so shipping costs are high. A large local retailer might be better for that. Or use egghead.com, which has (at least used to have) a limit of $9 on shipping for all items.
Buy.com is currently at war with Amazon.com so is offering FREE shipping on a lot of items, including monitors.
the DOE's Fermi Lab in Illinois.. particle acceleration loving.
You may not be able to get close. They've added a bunch of post 9/11 security rules.
We had a meeting of Uniforum Chicago with Randall Schwartz scheduled to meet in Fermi's auditorium. Due to the new security concerns they made us relocate the meeting at the last minute.
We don't want those baddies to steal our particles do we?
He's since gotten some feedback from movie goers that that isn't necessarily the case. Some complain about obvious pixelation and artifacts in the low resolution of the digital AOTC.
After seeing how lousy digital cable and digital satellite TV can be when they skimp on the bandwith, I'll remain a skeptic.
And once everything is outsourced and all of the critical data lives on servers that are not owned by the DOD, THEN the fun will begin.
New project? Not in the contract. We'll let you know when we'll even answer and how much we'll gouge you for working on it. It not like we have to deliver a competitive bid is it?
Something's broke? Sorry - fixing that is not spelled out in the contract. It'll cost you to fix it. No, it doesn't matter that YOU used to handle this with no sweat. Not in the contract.
Been there. Watched that. Worked on undoing it. ( It was a different three-letter outsourcing company, but he same song.) The bosses thought they'd save money. Current IT budget X. The outsource contract is bid as 0.9 X. The work they'll do, which IS specified in the contract is 0.4 of what we did for X.
I once saw a lawyer carrying the actual contract. It looked like the Oxford Engligh Dictionary. Amazingly though, every new hire entry-level desktop tech KNEW what wasn't in there.
I thought they got the bomb from an Israeli jet that had crashed in the 1967 war. It originally had a nuke attached, but the ground crew forgot to detach it when they were rearming the plane with conventional bombs. The plane crashed and the bomb landed in a field in Lebanon or Syria. Some farmer eventually ploughed it up and reported it to his local Hezbolla chief.
If I recall. It has been a while since I read the book.
You got it right. The bad guys were Muslim terrorists, too. They used an East German nuke scientist to make the conventionat Israeli nuke into a H-bomb and set it off from a news van parked outside the Super Bowl in Denver(Phoenix?) The President was supposed to be there with his girlfriend and he takes the attack as attempt on him personally.
According to Roger Ebert the movie changed the bad guys to neonazis so they could sell it in Arab countries, where action pictures do well. I'll bet they wish they had reconsidered that decision after 9/11.
I once asked about this. The telco said it is a surcharge (about USD 3, last I checked) just for having access to those various 1-900, 1-876, etc., toll call numbers. ATandT charges I believe USD 6 just for being listed in their books.
I use an internet calling card exclusively and was looking to drop long distance on the land line altogether. The fact is, you CANNOT, unless you go to the extreme of having NO land line. In the age of wireless communications this is of course possible, but I don't know of a cellular phone contract that works out to being less expensive than a land line.
That's not true for me.
I got really pissed when my $.05 a minute IDT service was costing me $7.00 a month in minimum usage charges, fees and taxes. $7.00/0 minutes is INFINITE cents per minute.
I changed my local lines to NO LONG DISTANCE.
You have to be careful what you say because the local telco rep is not allowed to recommend or influence your LD carrier decsision in any way. The sleezeball long distance companies have registered words like "whatever" and "I don't care" so may you get Fast Eddie's Ripoff telco if you say that.
I bought an AT&T calling card at Sams Club that was $39.00 for 1000 minutes. No more fees to pay. I just gotta dial a lot of numbers the few times I call long distance.
To use Love's term, they are "streamlining" their business.
After I was let go, a startup I worked for put out a press release that announced they lost the last of their installations and that they were "downsizing."
To which I thought, "Yeah, 'Downsizing.' Meaning 'We're getting rid of those pesky customers.'" They went bankrupt shortly thereafter.
...and not to mention that nukes are set off in the air cause it delivers more of the blast to a larger area (true for conventional bombs too - daisy cutters, made popular recently in Afganistan do this, ususally with a long pole to touch the ground and trip the detonator at about 20ft.) Both Little Boy and Fat Man were detonated by a radar that estimated the distance to the ground and set the bombs off at about 2000 and 500 feet above ground level, respectively. While it is possible to do that with a timer, I really doubt it's ever done.
I just yesterday looked at one of the Fat Man test casings at the EAA AirVenture museum. I saw the radar antenna. It also has a barometric port and four little propeller blades. My guesses: The barometer would be used to arm at a given altitude. The props would drive a mechanism set that the bomb would only arm after some given number of spins as the bomb feel through the air.
I guess they didn't have Nixie tubes in the 1940's.
The schematic diagram attached to the case had a large section in the middle missing. It said that parts were still classified. I hope so, or Saddam just could buy an admission ticket and take a picture.

My favorite Hollywood cliche is the huge Nixie tube countdown clock, usually on a bomb so we can have the tension as the hero does whatever he has to do before the clock hits 00:00.
In "Daylight" Stallone goes deep into the tunnel ventilation system and through the temporily stopped huge fan to find the clock mounted on the wall ON THE INSIDE telling him how much time he has before the fan starts spinning again. WHO would EVER see that clock where it is?
In "Broken Arrow" and "True Lies" and countless James Bond movies we have the H-bombs which have the clock timer/display and a key pad/key switch to arm/disarm ON THE BOMB which is, of course, usually carried way down in the bomb bay of a bomber. Who is supposed to see the clock, insert the key, and punch in the codes? The crew is some distance away when the bomb is launched and they will want be a LOT further away when the clock hits 00:00.
And the only way you can outrun the blast from a huge explosion is if you can put the blast in slow motion while you're in the foreground running at double speed and even then it's a good idea if you're in a studio far from the blast.
I own two TiVos. TiVo keeps track program information, which they sell to Nielsen for TV ratings and they record every key press on the remote, for useability data.
They offer TiVo owners the choice to Opt-out of supplying the information if they choose.
The TiVo DVR collects certain types of information from its users, including Anonymous Viewing Information, Diagnostic Information, Commerce Information, and Service Information.
I'm cool with that. I haven't even chosen to Opt-out. I hope I have some influence on the ratings so we get more decent shows.
What is it with these damn USB modems? They're a pain in the rear arse. I assume they're cheaper than ethernet ones. But is that the real reason, or is it because it makes it harder to share an internet connection? Yes, I know it probably can be done, but that means having to keep a computer online.
What's up is that the ISP wants equipment that as easy as possible for brain-dead mere mortals to install. With USB in Windows, Plug-and-Pray pretty much works. With Ethernet, there's a strong chance that you'd have to tell the user how to open the PC case and install a board. Messy.
Of course, the joke is that what they gain in ease of hardware install they I
lose when the USB IP drivers trash the system.
