This is the simplest way to schedule tweets to Twitter. If you want to seriously start building traffic to your web site then regular tweets are essential.
First, make sure you have curl installed. cURL is often already present in Linux distros but Windows users will need to locate and install it.
The command is very simple which can be placed in a shell script (Linux) or a batch file (Windows). This can then be scheduled as you wish - I suggest you don't over do it, the same message every minute will not be posted as it will be identical to your previous one and Twitter will reject it. Keep repeated messages a few minutes apart.
Right, down to the nitty gritty.
The command is fundamentally straight forward:
curl -u username:password -d status="Lets's have a excellent ancient tweet. http://goodoldtweet.twt" http://twitter.com/statuses/update.xml
The username:password is honestly obvious - just replace it with your own Twitter account login details.
The text following -d status= is your tweet message (I included my blog url).

Now, this produces output to the screen and is helpful when you want to know that the command has worked and what it did. But, this is no excellent if you want to automate the command. Screen output will cause an error in scheduled running of scripts and applications. Fortunately there is a way around this.
I shall show you how to do this in Linux as I currently don't know the equivalent in Windows (it may be the same in Windows but don't count on it).
curl -u username:password -d status="Lets have a excellent ancient tweet. http://goodoldtweet.twt" http://twitter.com/statuses/update.xml > /dev/null 2>&1
This makes sure that all output is cleanly dealt with without causing errors.
The shell script in which you place the command can now be scheduled as you wish.
It's happened. Well nearly.
Supersonic performance.
The race to petaflop supercomputers is heating up, with the latest entry coming from NASA, Intel and SGI. The trio announced plans to build what will be a petaflop-capable supercomputer by next year, and up to 10 petaflops (define) by 2012.
Supercomputers have been in a constant game of oneupsmanship and bragging rights. The definitive list of the fastest supercomputers, called Top500, is released twice a year, and for the last few years, IBM (NYSE: IBM) has dominated with its Blue Gene/L supercomputer at the Lawrence Livermore Laboratories.
With each update to the list, the number of teraflops (define) goes up because no matter how much processing power you give these machines, there's still more demand for them. These massive systems aren't just doing one job at a time. They are rented out to other agencies or researchers who have a massive computing task they need done.

At any given time, a supercomputer likely has hundreds of computational tasks running on it. So there are never enough teraflops to go around. A teraflop is a trillion operations per second. As of last November, Blue Gene/L topped out at 600 teraflops and ran at a sustained rate of 478 teraflops. By contrast, a Core 2 Duo E6700 processor performs around 12-13 gigaflops, or billions of operations per second.
