I was recently introduced to Cayenne by a member of the Cayenne team. The concept behind Cayenne is to make creating Internet of Things applications much easier for new users just starting on the Pi.
The interface allows dragging and dropping of components, scheduling, and configuring triggers for events all through a web interface!

About a month ago, I was contacted by the Kano team and was offered an awesome chance to try out their amazing Kano Computer kit.

I received it earlier this month but didn’t get to play with it until now, but as they say, patience is a virtue!
But without further ado, lets start having a look at the Kano Computer Kit.

For those who actually do follow my blog, you may have noticed the lack of posts recently. This has been because I’ve moved house!
But I do have some posts that I really do need to get to, and also still need to try and set up my workspace so I can get back to putting up quality posts.

For those who would like to check out what I have coming up, keep reading!

This post is more of a note to myself on how to install the proprietary nVidia drivers on a fresh Debian install as I keep forgetting which packages I need!

After recently reinstalling Jessie onto a computer with an older Geforce card, I had to install an older version of the drivers (340.96).

From a fresh install, I needed to install the following packages:


# apt-get install gcc make linux-headers-3.16.0-4-amd64

The kernel version above will change as time goes on, so you can substitute the version number with $(uname -r) – e.g. apt-get install linux-headers-$(uname -r)

Once the packages are installed, you need to make sure the gcc version that your kernel was compiled with matches your current compiler.
You can find out what version your kernel was compiled with by checking the contents of /proc/version
# cat /proc/version
Linux version 3.16.0-4-amd64 ( (gcc version 4.8.4 (Debian 4.8.4-1) ) #1 SMP Debian 3.16.7-ckt20-1+deb8u4 (2016-02-29)

In my case, my kernel was compiled with gcc-4.8, so I had to also install gcc-4.8.
# apt-get install gcc-4.8

Once the compiler was installed, I also need to set the CC environment variable so that the correct compiler is used to compile the nVidia driver.
# export CC=gcc-4.8

Now that everything is setup, I can run the nVidia installer to install the drivers.
