You arn't the only one to listen to Chemical Brothers while driving a tractor. *grin* You are correct on your points. In the 'high-tech' industry, it's almost never your own money you are spending on stuff, so who cares what it costs, as long as it makes your job easier? On a farm, if you spend a whole day going up to a repair something, you are out lots of time and money, and you don't have $6Billion of someone elses money to take it from. You *have* to fix it. That mind-set is part of the reason I'm as good as I am. (not saying I'm all that great, but if I didn't think like that, I'd be worse) *heh*
Yes, Marcelo is the maintainer of the V2.4.X kernel series, but the Linux kernel is only a part of the software out there. open source software includes things like apache, and samba, and BSD, and mozilla, all sorts of totally cool things. Although I am a fan of Linux, even I must admit that it's not everything.
I think I worked with him.
The guy I am thinking of (probably not the same actual guy, but this is a good place to post some stories) shorted out/removed power from:
Phone system: 2 times when management was in a VERY important conference call.
ENTIRE SERVER ROOM: twice.
Network stack: three times.
Brand new $200K worth of servers: 2 times.
His own brain: Once too often.
I've use some boards that have it (Intel G440LX series) and it's great.
The problem is (of course) finding a board that has that feature. I'm afraid that most boards in the 'budget' range will not do this.
If you have a bunch of them at a colo, you can daisy-chain the serial ports, (So the console from A is going into B, the console from B is going into C, and so on until the console from X is going into A) The only way to totally lose a machine is to lose ALL of them.
One of the problems that a lot of the 'dot-bombs' have seen is that their product is just fine, but occupies a niche that just isn't a large market. I worked for a company that had a half-way decent product, and the revenue of this product could have supported a dozen people, or even twenty or so. But our CEO (who couldn't add 13 and 7 correctly) was hyped, and thought we needed a 100+ employee company, and millions of dollars in investment, and that we could make billions of dollars. NO. Not every product is a revolution. Not every product needs to have a "225-person workforce"
Advice to executives: Don't hire unless you need some work done that your current employees can't handle.
I was talking to a friend who still worked at a place where I had been previously employed(Both of us in IT), when he mentioned that they had moved their web services to a 'professional' hosting company. I had been playing around with SAINT, and during the conversation, (I forget who mentioned it) we decided to scan the machine hosting their site. The scan showed anon FTP with write access. I logged in (anonymous) and noticed that I had write access to the entire site, including all the scripts that dealt with the credit card numbers. After checking to see that the write access was real (I created a file in the root directory, containing my name and phone number, and an explanation of what I was doing) I told my friend to have that company called up and have the problem fixed immediatly. Later that day, I got a phone call from the 'professional' company that was hosting them, slightly upset at my actions, but just happy that I *was* benign. They could have done the same to me as has been done to Brian West, but instead they fixed their problem, and let me live.
Some people (usually overclockers) have been doing something similar to this for quite a while. The way it's worked until now is that they run a program (waterfall for windows, or automatic under Win2k and {of course} Linux) that issues the idle command if the processor is otherwise idle. This saves energy, reduces heat, blah, blah, blah.
The problem is then exactly the same as here:
You've got a super-fast CPU, but you can't actually use it for long, intensive tasks.
(i.e. 5 minutes into a game of Quake, the system will become unstable)
The solution? *shrugs* Hard to tell. Wait for a CPU that won't do this. (AMD!) and don't overclock so much.
Note: I love overclocking. I've overclocked every system I've had since my 483/33 My current main system won't overclock more than 5MHz. Life sucks for me. But I'll overclock my next system.
I've experienced a couple of (two) power outages at work, and here is what happened: Background: ~250 users, 1 server room, everything in the server room had about 15-30 minutes of UPS time #1: Everyone ran to the server room. (Time=0) #2: Everyone just stood around for a bit. (Time=+1min) #3: We started shutting down Unix machines. (Time+1.5min) #4: Power came back online. (Time=+2min) #5: We discussed it after the fact, and decided that it was appropriate to wait several minutes before shutting down the servers. (Time=+1day) #6: Power went out again. (Time=+1.5weeks) #7: See steps 1-5
Basically what happened is that one of the management yelled down something like 'Should we shut the servers down?' and we understood 'Shut the servers down'
On a lighter note, one of my fellow sysadmins thought it necessary to have the printers on UPS that way if the power went out, everyone could finish printing.
Question: What are the options for a small-to-medium server room? (about 15-30 middling sized computers) Right now we have a single largish UPS, which says it's running at 40-60% of capacity. (depending on if I have the staging DB powered up) As we gain 2 more of those systems, and several other power-hungry systems, I know that our current UPS will not provide more than a minute or two of power for everything. We are not even monitoring it at the moment (we just hope that the power doesn't go out).
They did not steal internet access. They had already paid for internet access. Internet access was not offered at their location, but was offered 300 feet away. They used their internet access there, and ran a cable to their room. No problem. Also: They couldn't just 'buy a damn modem and deal with 56k' Didn't you read this stuff? They have to: #1: Buy a modem. #2: Buy additional access through an ISP. #3: But a digital-to-analog phone converter (NOT a modem, you stupid {deleted}.) #4: Only use it after business hours.
Not a modem. They will use a modem, and since their phone service is digital (How can the university afford that sort of stuff but not a cheap hub and some ethernet cable?) they will then have to have a digital-to-analog converter. Their data transmissions will look like one of these: [computer]---(analog)---[phone converter]---(digital)---(converter)--{exit university}--(analog)---[telco] or [computer]---(analog)---[phone converter]---(digital)--{exit university}--[telco] Or basically the same thing with one or more conversions between the university and the telco.
Hello? They don't pay $24/semester for net access. The students already have net access paid for. Read the article(s). The $24/semester is for the cable to their room. They did not have that option.
What they did was simply use the network resources that WERE available to them, legally, in an un-anticipated way.
Yes, they did. he $24/semester is for the hardware use to their room. Did you not read the article? They were allowed to use the network. Why? Because they paid for it.
In all honesty, this isn't a matter of theft, this is a matter of the university administrators being 'pissy' because a couple of kids can do for free what they can't pay money and have done.
They did not have the option to pay $24 a semester and have access there. NO access was possible in that dorm. In order to get (legal) access, they would have to move.
What is interesting is that they did for free what the university can't afford. And now the university is punishing them for it.
If I had a college student make the cases, I could see probably 500MHz, 128Mb and ~3Gb nodes (100Mbit) for about $400 each. So a 10node system would be about $5k and a 20 would be $10k (upper limits on pricing) Hmmmm.
Have any of you been running th 2.3.X kernels on your board? I've found that when I do, I get APIC interrupt errors. This seems to be a problem specifically to the BP6 board, that is compounded when the board is overclocked, and when it i running hot. (as in the d.net client) Also, I would like more information on what people are using for that hardware monitoring. lm_sensors seems to be the only option I've found, with several different GUI interfaces. Are there any other options?
Just because the genetic material is not all exactly the same does not mean that the diseases are not the same. The way that they do the cloning is not very accurate, and will result in adding some new disease, or a third arm or what-have-you just as often as taking a disease out. I'm not trying to deny that they might be able to do what you are talking about eventually, but we are no closer than we were in the first place to having the forever man. We still have to learn how to replace parts of the DNA with other parts, (genetic surgery), and THEN clone.

What does everyone else use?
How expensive is it?
Can we upgrade or do we have to purchase new?
