About Me

image_pdfimage_print

WELCOME TO MY WEBSITE

I am the documentation lead for the ToriOS operating system.  This is designed for older systems as it supports non PAE hardware.   ToriOS is a GNU / Linux based and is built on Ubuntu 12.04.

For the documentation I am using the LaTeX typesetting system as it just works.

I also run the Torbay Raspberry Pi jams, along with other members of the Devon and Cornwall GNU / Linux user group.

I work as a play worker in an after school club but would like to work as a teaching assistant or similar and support the new computer science curriculum, as

I also have some coding skills in python and scratch.  I have my own github repository with projects,  which may be good to use in schools to see what can be developed with some of my mini projects.

I use GNU / Linux at home and have done for several years.

I am committed to safeguarding children, young people and 
vulnerable groups and expect any school or establishment I am 
involved with to share this commitment.

Xubuntu and Fritizing

* Since posting this, I have found a fix,  please scroll to the END of the post, where you will find a link.   I am leaving the main body intact for historical / context purposes.

I still seem to be having issues installing fritzing on xubuntu 14.04

this is what I am doing

sudo apt-get update

sudo apt-get upgrade

sudo apt-get install fritzing

This produces the following error :

psutton@ER1401:~$ sudo apt-get install fritzing

As the package is downloaded to :

then from there run

sudo dpkg -i fritzing_0.9.0b_i386.deb

which produces

I have also tried to manually remove the xml file in

with sudo rm /usr/share/fritzing/sketches/index.xml

but this seems to fail.

 

Any help or suggestions would be helpful

 

Further to the above set of issues I seem to have found a fix

Battery discharge

image_pdfimage_print

I recently built a very basic battery discharge unit, so that batteries could be run down easily.  This works well with rechargeable batteries so they can be recharged from low.

battery

Essentially this is a battery holder in series with a 6v bulb in a holder.   It works and can discharge 4 batteries in a few hours.

Linux mint – live test

image_pdfimage_print

I have tested Mint 17.1 live cd.  (well live flash disk) created this with unetbootln.  Anyway booted up fine.  I then went to the printer section and added my printed (which was auto detected) and printed a test page.  All this from a Live CD.

This is in test for a install I am doing over Christmas for a family member who’s Windows 7 computer is completely messed up,  so I am installing a proper OS to replace Windows.

The fact you can install printers from a live cd means that if your computer messes up it should be possible to :

Boot live cd

Install local printer

Mount affected hard disk

find important documents and print them

As Libreoffice is included then it should be possible to open and print MS office documents or if you’re using open standards just open a native ODF document and print.  Either way if you have that all important document to print you have a lifeline.  Plan B would be to mount a usb flash disk and copy said files to that, then print on another computer.  But if you are taking files off a possible virus infected computer you should scan these before they go to a 2nd computer as that could get infected too.

Just enough OS (jeOS)

image_pdfimage_print

A couple of months ago, I re-introduced an old friend — Ubuntu JeOS (Just enough OS) — the smallest, (merely 63MB compressed!) functional OS image that we can still call “Ubuntu”.  In fact, we call it Ubuntu Core.

This looks interesting as a base to develop bigger systems

“Suncor Energy: Don’t destroy Canada’s most important river!

image_pdfimage_print
Energy giant Suncor is spending millions on a PR blitz to
convince Canadians that it cares about the environment — even as
it's lobbying to be exempted from the water regulations that
protect one of the country's most important rivers.

The Athabasca River is an essential ecosystem for hundreds of
species of fish, birds and other wildlife, not to mention the
drinking and farming water for miles around.

NASAs Orion blasts off

image_pdfimage_print

Today saw the launch of NASAs Orion rocket on a test flight which may one day pave the way for people to land on Asteroids and eventually Mars. Or this is the hope.

Further mission information can be found on the NASA mission page.

A video of the launch can be found here. (Youtube video)
