Buying a stove for your woodland or camping expeditions can be daunting with a vast selection on the market and strong opinions on the forums. Here’s my take on it.
In the bygone days videos and films were rented from shops on reflective pieces of plastic and magnetic rolls of ribbon. This is a software development task and an implementation task. (Taken from OCR 2507 Task 1 Jun 2006)
The Magic 8 Ball is a toy used for fortune-telling or seeking advice, manufactured by Mattel and developed in the 1950s. Often used in fiction and for humour related to it giving very accurate, very inaccurate, or otherwise statistically improbable.
Dogs do not age at the same rate as humans. Write a program that converts the age of a dog to the equivalent for a human.
Write a Etch A Sketch program that recreates the popular 70s/80s Etch A Sketch toy.
A cellular automaton is a collection of “colored” cells on a grid of specified shape that evolves through a number of discrete time steps according to a set of rules based on the states of neighboring cells.

So if you are one of the few lucky individuals to own a woodland you might be looking for a mode of transport that can be used to move wood and tools around your space. Whilst there are a number of potential solutions, briefly covered below, this post explains why sit on lawn tractors provide a cheap and economical solution.
Not any old sit on lawnmower will do. What you are looking for is ideally a Garden Tractor (left) or even a Lawn Tractor (centre). A small standard sit on lawnmower (right) is not going to work for woodland work.
Garden Tractors can usually be spotted as they have a horizontal drive shaft, PTO at the front and/or rear and bolts hubs. Lawn Tractors are very similar but will typically have vertical drive shafts, single under PTO for the cutting deck and key shafts for the rear wheels. However, the big advantage of Lawn Tractors vs Garden Tractors will be cost.

Morning all. Continuing the theme of small stove reviews I took some photos of our Ecozoom in action this weekend.
Initially when we got our wood we bought a Kelly Kettle Base Camp Kit for around the £99 mark. And whilst it is easy to light and will boil 1.6L of water quickly I must admit to being disappointed. The key negatives of the Kelly Kettle for me are:
So looking around for alternatives we finally settled on and purchased an EcoZoom Versa for around £110 and are so pleased with our purchase.
Since owning ours, we’ve done the essential sausages and burgers on it, cooked veggie stew for 8 using a Dutch oven and made many teas and coffees and in our opinion the stove has a number of advantages over the Kelly Kettle including:
If I had to find any negatives I would say the only downsides are:
They are comparable in price to the full Kelly Kit or if you are feeling the DIY easy to make yourself. This one is made from a chip oil container and piece of flue pipe!
A film society has over 300 members who are able to borrow from its library of more than 1000 classic films. There is more than one copy of some films. The films may be held in video cassette form, DVD form, or, in some cases, both.
Members pay an annual membership fee that allows them to borrow films free of charge. Members can only have one film out on loan at a time. Loans are not permitted to extend beyond seven days.
The film society needs a database to contain details of its members, its films and those films currently out on loan.
The table of members is to contain appropriate contact details for each member and the date on which their membership fee next becomes due. It should also ensure that a member can only borrow one film at a time.
The table of films is to contain information about each film copy. It should store the name of the film, its director, its year of release and running time, as well as a brief synopsis of the storyline.
The loans table will identify which films are out on loan and to whom.
(a) Members Table
(b) Film Table
(c) Loan Table
(d) Data Input
Create suitable data for each of your tables. Although the film society has over 300 members and more than 1000 films, your tables need only show a sample of the records the film society would hold. You should not attempt to create the whole database. Instead, your Member and Film tables should each hold at least 20 records. Your Loan table should hold at least 10 records. You should choose your data to be suitable for producing sensible results in the remaining questions.
Include a full printout of each of your tables. Screen shots are acceptable. 
(e) Database Queries
At the film society library, members should be able to interrogate the database. They should be able to: print a hard copy report of information about an individual film title; print a hard copy report listing all films made by an individual director; and run an alphabetical screen listing of all films currently available for loan. Create interfaces (of which there should be hard copy evidence) that allow a member to:
(i) input the name of a film and output to the printer the information held about that film. Provide at least two sample reports.
(ii) input the name of a director and output to the printer a list of the society’s films made by that director (with the years of release and running times). Provide at least two sample reports.
(iii) output to the screen a list, in alphabetical order, of all films currently available for loan. Provide hard copy of one sample page of your screen.
(f) Mail Merge
Create an interface that allows the film society to send mail merge letters to any members whose loans are shown to be overdue. Provide hard copy evidence of your standard letter (with mail merge fields) and show that your mail merge produces suitable letters to all members whose borrowed films are shown as overdue in the Loan table.
