CPU Convective Water Cooling
biso writes "The possibility of cooling a CPU with gravitational convective flow of water is here analyzed and experimented with positive results.
Many liquid cooling systems have been experimented by overclockers to better dissipate the heat from CPUs. The major part of these coolers is characterized by a relatively complex system requiring pumps or other active devices. Sometimes even liquid nitrogen is used. I built a simpler cooler, able to dissipate the same heat flux of a normal heatsink."

Piss!
Because all operating systems are written by programmers, I assume that any operating system is much smarter than me. Thus, any good operating system should try to outsmart me by restricting my options at every turn. Linux, like all versions of Unix, is lousy at restricting my options because at the command line virtually any operation can be performed with ease. (For example, 'rm -rf /win' could 'delete an entire mounted directory, with no popup window warnings whatsoever.)
I'm proud to say that there is no such danger in XP. Windows pop up when I want to make a change, and then more pop up to ask if I'm sure I want the change. Thankfully, Windows XP looks after my computer's well-being by occasionally switching configuration settings from the way I want them to what the OS programmers think they might probably ought to be. Boy, I'm just impressed with how smart they are. Once I learned to live with whatever the default settings are on any new hardware I install, I can't say the number of hours I have saved.
I use that spare time to reboot my Windows XP machine multiple times a day. Technical support personnel recommend that I do it regularly-- kind of like brushing my teeth. To help remind me of this necessity, windows pop up to tell me to reboot whenever I make a configuration change. By now my machine is minty fresh, I figure.
There is no such useful rebooting in a Linux system. It is as reliable as the sunrise, with uptimes in weeks, months and years. Virtually no configuration change requires a reboot, to boot. Imagine all that plaque in the computer. Gross!
In XP I am prevented from making dangerous fundamental configuration changes unless I use a special "registry editor". I have found it so useful to have this separate editor that I hope in future versions they go all the way and supply a separate editor for each file on the disk-- in that way windows could pop up at every keystroke to warn me that changing any line in the file I am editing could cause the system to not run properly. If this were only the case, people would finally learn that it is best to just stick with the mouse and they would be freed of the need to constantly move their hands back to the keyboard. (If one stops to think about it, the mouse is a much better device to use than the keyboard. Ever hear of someone getting carpal tunnel syndrome from a mouse? No. It's comfortable and ergonomic. Like Morse code devices. That's how long distance communication started, after all.)
Linux, by contrast, requires no special editor to change configuration files. The fact that there is no "registry" in Linux allows the abomination of using any text editor whatsoever to do the configuration. Can you believe that configuration files are usually stored clear text? Talk about dangerous!
I am also happy to report that I have experienced no truth to the rumor that Windows disks become corrupt after improper shutdowns. Indeed, I have been forced to improperly shutdown the machine innumerable times after it locks up, and I have no apparent problems to report regarding the disk. No such claim can be made for Linux. They say something about lack of data points. Excuses are all I ever seem to hear from the Linux crowd.
By sheer size alone, Windows XP beats Linux hands down. It is so much bigger, it is _obvious_ that it is better. Why would you want a small OS with the large disks and RAM sizes we have these days? For this reason alone, I heartily recommend Windows as a way to maximize resource utilization. Your CPU and disk will constantly be pegged to the limit, the way god intended. The Linux kernel and drivers accounts for only about 750KB. Why, even the Microsoft Win16 subsystem uses more space than that.
It is no surprise that Windows XP costs $300 on the retail market and Linux doesn't cost anything. People know what they want, and they want Windows XP. Because Linux is free, that means it's basically worthless. The same goes for all the development tools, remotable GUIs, and applications, which all cost money for Windows (i.e., are worth something) and free for Linux (worthless!).
Installing software is very easy in Windows XP. I usually slip in CDs without even reading instructions or warnings, and just double click on whatever window pops up. There is no need to read anything or touch the keyboard. (Did I mention that I hate that thing?) Well, OK, I have learned the hard way the machine locks up if I don't take the time to close all other applications.
Linux, by contrast, requires typing on the keyboard to get anything to install at all. And you always have to know the NAME of program you want to install. For example, in Slackware, you have to type "pkgtool" to install a program. Linux needs to get with the 21st century!
Windows XP follows the DOS convention of putting \r\n at the end of every line of a text file. While this is only a mild concern because of the relative rarity of text files on Windows machines these days-- thank god--it helps to differentiate between the text files and the other files. Sadly, Linux makes no distinction between text and other files.
If I legitimately purchase Windows XP, I can call Microsoft customer support to get help with my problems. After a short hold time of an hour or so, they always help me. Ever since I told them that I was dual booting to Linux, they were able to flag my account and now each time I call even the entry level support personnel I am connected to say that Linux is the source of my problems. Everyone seems to agree that Linux is no good. The more I listen, the more I'm impressed with the knowledge of the support staff there.
By contrast, in Linux, all I have is stockpiles of resources and documentation that I would actually have to read in order to understand. Sure, I could obtain Linux support from a commercial organization, but they would probably just tell me I have to use a text editor to fix up my system.
In the end, I have no need for that old computer donkey Unix. I don't need to run big Unix tasks, after all. I refuse to become one of those a bug-eyed computer users, that's for sure. As soon as I can keep Windows XP from crashing for long enough, I'm going to delete my Linux partition, i.e., the equivalent of moving it to the Recycle Bin, saying that I'm sure, emptying the Recycle Bin, and again saying that I'm sure I want to empty it.
WTF is OSG?

On November 19, 1954, the career of Sammy Davis Jr. almost came to a sudden and tragic close. While driving to Los Angeles to record the title tune of the Universal International picture "Six Bridges to Cross", Sammy was the victim of an automobile smash-up and narrowly escaped death. He was so seriously injured that his left eye had to be removed. In spite of the terrible shock, Sammy rallied and went on with his work; he even insisted that he ws the "luckiest guy in the world".
Since his accident, Sammy's courageous spirit and ever-growing talent have won him increasingly enthusiastic audiences. Let's hear it for Sammy Davis Jr. !
