Re: [CGUYS] Speeding Up XP [Was: Vista Memory Needs
I only had time to read the 1st article, but it didn't demonstrate knowing anything about how prefetch works. As I noted initially, if the test does not test what the fix fixes it is not much of a test. The prefetch tweak is for system startup times, not app startup times. THAT'S THE TEST. Prefetch is supposed to speed up application launching, not the startup of the OS. When prefetch is working it does this. When the prefetch file is corrupt it does the opposite -- greatly slowing application startup. Correct. That there was something wrong with *your* prefetch cache does not invalidate the conclusions that routine prefetch clearing does nothing under normal conditions. * == QUICK LIST-COMMAND REFERENCE - Put the following commands in == * == the body of an email send 'em to: [EMAIL PROTECTED] == * Join the list: SUBSCRIBE COMPUTERGUYS-L Your Name * Too much mail?

Re: [CGUYS] Speeding Up XP [Was: Vista Memory Needs
Many years ago I witnessed a laboratory demonstration of the power of lightning. They rigged up a very high voltage spark (a shadow of a real lightning bolt) and had it jump to a block of wood. In an instant, the spark jumped and the block of wood was just gone. In that instant, all of the moisture in the wood was turned into steam, and the steam just shattered the wood into dust. Once an hour at the Franklin Institute. I wonder if they still do this? * == QUICK LIST-COMMAND REFERENCE - Put the following commands in == * == the body of an email send 'em to: [EMAIL PROTECTED] == * Join the list: SUBSCRIBE COMPUTERGUYS-L Your Name * Too much mail?

Analogy: A surge protector is like a bucket that the surge energy is dumped into. [The excess electrical energy is turned into heat by the surge protector.] After the surge is over, the bucket is emptied, [the surge protector cools down] but if you look closely, a small amount of the rim of the bucket has been burned away [the surge protector is slightly damaged with each surge], and it doesn't hold quite as much. Not all surge protectors have the same size bucket. Some are too small. Normal surges are like a cup of energy; bigger surges are like a quart or even a gallon of energy. A lightening strike is like a tanker truck of energy dumped into the bucket. The bucket is so small in comparison, that it's swamped; [the heat energy raises the temperature of the surge protector way beyond what it can cope with] it doesn't matter if it's there or not. Many years ago I witnessed a laboratory demonstration of the power of lightning. They rigged up a very high voltage spark (a shadow of a real lightning bolt) and had it jump to a block of wood. In an instant, the spark jumped and the block of wood was just gone. In that instant, all of the moisture in the wood was turned into steam, and the steam just shattered the wood into dust. Not to burst your bubble, but in my personal experience surge protectors are worthless for lightning strikes. Our home was hit by lightning in 2003 and at least one piece of equipment was fried on (a) the AC line, (b) the phone line, and (c) the cable TV. Not sure where the jolt actually came into the house but it fused a phone line (physically welded the conductors)knocking out a couple of telephones and a fax machine, wiped out the cable box (no connection to the phone system) in the family room, and fried my WiFi access point (connected to a cable modem that suffered no damage -- go figure). And all the affected gear except the telephone handset was on a surge protector. -Mike -Original Message- From: Computer Guys Announcements and Discussion List [mailto:[EMAIL PROTECTED] On Behalf Of Eric S.

Besides the --- waste of electricity My brother and I have different takes on this. He is a power off guy, I'm a power on guy. Since day one I've always run 24/7 with all my electronics. In the tube days it made sense to switch off, but then you had to wait for the set to warm up. --- greatly increased exposure to corruption from power fluctuations and network baddies Not with a hardware firewall and a good UPS. --- 24/7 operation brings on the inevitable failure of $10 cooling fans which then can cook your chip Possibly a valid point. However, the most stressful moment for electronics is the initial power cycle (i. e., turning it on). The only real danger that I can see with an always on condition is lightning strikes. Overvoltage conditions, in other words. But we have surge protectors for that. * == QUICK LIST-COMMAND REFERENCE - Put the following commands in == * == the body of an email send 'em to: [EMAIL PROTECTED] == * Join the list: SUBSCRIBE COMPUTERGUYS-L Your Name * Too much mail?

Lightning is pretty darn powerful, that's for sure. The other problem with home surge protectors is that you can't tell if they are good any more. My understanding is that if it protected you from some regular surges already, it may not be doing anything any more. I'm sure someone on this list can elaborate. -- John DeCarlo, My Views Are My Own * == QUICK LIST-COMMAND REFERENCE - Put the following commands in == * == the body of an email send 'em to: [EMAIL PROTECTED] == * Join the list: SUBSCRIBE COMPUTERGUYS-L Your Name * Too much mail?
