Links design patterns and embedded systems, but in the narrow case of safety-critical systems, and once again interastingly doesn't seem to take account of users, and has a non-functional requirements focus, quite explicitly, without considering any other focus (seemingly assuming that design patterns wouldn't apply).
"Gross and Yu [12] discuss the relationship between non-functional requirements and design patterns,"
"This representation focuses on the implications and side effects of the
represented design method on the non-functional requirements
of the safety-critical embedded system including safety, reliability,
modifiability, cost and execution time."


You need to be between 16 and 24 to take part in work experience with futureCoders. You will be gaining work experience as a 'junior developer'. Being able to programme is essential. If you haven't learnt yet, you could join one of our coding workshops which will help you to start learning on your own as well as with others.
You will be a full member of our development team and will play your part in getting our projects delivered. This is a unique opportunity to learn what it is like to work in the software development industry, to make new friends and to be part of making something for a good cause.
You will commit to working each Saturday and one evening during the week in our Chatham office. You will be a full member of our development team and will play your part in getting our projects delivered. You will be expected to work remotely for a further half day on your code. This commitment is expected for a minimum of three months, for the full life of the project. This is a unique opportunity to learn what it is like to work in the software development industry, to make new friends and to be part of making something for a good cause.
The application process opens up before each new project. For information on when the next application window will be open please contact us via email to find out more.
We need people with programming experience to pair program with students and to do code reviews. We need volunteers to help at Coding Workshops and Project workshops (where students bring along their own coding projects and we support). We need volunteers to come along to events to help make sure that our staff are supported. We need volunteers to take on various project roles (UX, UI, project management, scrum master, testing, etc). If you are interested, please get in touch: email<EMAIL_ADDRESS>to arrange to chat further.
That is fantastic. Have a look at the question below on volunteer roles and email us to arrange for a chat.
A futureCoders project is a great way for a teacher of computer science/IT to get teeth into a real project and to develop new skills in a supportive environment. A teacher would make a great volunteer and this would be a great CPD opportunity. If you are interested and would like to discuss this, please send us an email We would love to hear from you. We promise not to put you in a team with your own students.

That is fantastic. There are many ways in which companies can support our work. Could you loan us a developer? Could you host a project in your office space? Could you host an event? Could you take on a futureCoders 'graduate' for further, different work experience? Could you consider a futureCoders 'graduate' for a job or apprenticeship? Could you sponsor a student through the programme (it costs a minimum of £250 per student per month to put them through the programme)? Please contact us via email to discuss possible options.


NRPN 82,0 on the Editor input channel reads back the {MIDI_program_attributes attributes} and {_timestamp} of the current {_program} in the Main {_instrument} as a {MIDI_Program_Set_Attributes} NRPN 18,0. The Bank MSB and Data MSB values are ignored, but the latter must still be sent to trigger the operation.

Obama’s Lead in Delegates Shifts Focus of Campaign - New York Times
Obama is cutting at Hillary’s base. Hillary does well with blue-collar and lower income voters, making her a possible favorite in Ohio. Obama will most likely win Wisconsin. Texas? Who knows.
Super delegates. Super heroes or possible villains?
