For a product that I am working on, I need to attach a rope to the product. Simple, I thought, tie a knot. My first feeble attempts fell apart. Later attempts did the job, but looked a mess. A quick Google later, and I had a knot that seems to do the job. The tucked double overhand. Three simple images are enough to explain how the knot works. Moments later I had the knot off pat, and decided to show the production department.
All of a sudden we hit a problem. For some reason, no one else is able to tie this knot! I can’t believe that I am particularly gifted in this area, but maybe I am not a dumb as I think sometimes. Is this a hard knot?
This animation was done in Povray. I got fed up of trying to show the knot to people, so next time they ask, they will get a link to this.
I know that I have written about Apple before, but now I am a customer! The shuffle shown is my new music player. As soon as I had opened it up, I plugged it into me Ubuntu system to charge it up and load some songs. All my songs are in mp3 format, so that was not a problem.
Rhythmbox recognised the shuffle straight away, and loaded the songs without issue. I then used the player on my way to work. Part way there it started playing up. When I got to work, when trying to sort it out, the device locked up completely. The instructions suggest at this point that a full reset is required, which needs iTunes. Fortunately, I still have a working Windows installation with iTunes, so I upgraded to the latest iTunes, reset the device, and got iTunes to load some songs.
The device has been working just as it should since. When it comes to changing the songs, I will try Ubuntu again, and see how it goes.
From time to time, I get the the urge to play with Povray.
As can be seen, I am in the process of modeling my home. The idea was I could try out different arrangements of furniture and stuff, and get a view of what it looks like. We even may move some walls around, and this should help to give a feel for how it could look.
At the moment, I am still putting the walls in place. Two big gaps are the fire place, and the front door.
I have been having a little tinker again with povray. This time I needed a little Perl to help me out. All I need to do now is work out the maths to calculate surface normals. Anybody got some suggestions?
