Yesterday I got the feeling that I have taken the Perl method of slowing the CPU as far as possible so today I rewrote the script I had to accommodate a system call just to see whether this version would work interactively.
Not so much, as I assigned the “dd if” script to a subroutine in [...]
I attempted to build off encouraging signs that it might be possible to include a CTRL + C terminate command as a subroutine within Perl by clever use of ’system’ by mashing the scripts found on the following pages into some sort of Hydra but alas to no avail, most were concerned only with ensuring [...]
Having acquired a nice CPU intensive statistical analysis script I know intend to put this R script through its paces while under the duress of the CPU max out scripts. In each case the slowdown scripts are executed before the R script just to take every care that they supercede the R script in terms [...]
Today is all about getting a feel for how the computer copes with CPU stress, as such this is likely to be a boring blog post filled with mundane figures of more interest to me than anyone else…
Running scripts on tower pc
Initial Temp on boot = 21.8c
CPU usage – oscillates wildly between 28 – [...]
I’ve decided to some preliminary explorations of the slowdown scripts that Graham sent our way. Each one of them bumps CPU usage to 100% pretty rapidly
Method One:
dd if=/dev/zero of=/dev/null bs=1024 count=104857600
After running it twice the laptop temperature showed up as 56.5 degrees (usually it hovers at 37.5 degrees, ideally I would need to [...]
After I showed Graham some of the software and scripts which I reckoned could be of assistance in slowing down the computer, Graham came up with some additional solutions for the computation slowdown, one of which is effectively a ‘fork bomb’ that sends a process to the CPU and keeps subdividing it.
The other one copies [...]
Had an interesting conversation with Eleanor today about her project, she mentioned a guy called Friedrich Jurgenson - http://www.fargfabriken.se/fjf/life.html
Basically this was a creative type who began hearing voices on recordings – he even has a frequency named after himself.

Tech wise today was frustrating, I couldn’t resolve the [...]
