Reasons to own a Smart Phone

When we think about the things we need in life today, gadgets are probably the last on the list, if they even make the list at all. A lot of folks would think that this is just a desire, a frivolity that really can be done without. What most do not realize is how the world is wired today. Here are some reasons why a gadget- most probably a smart phone- has become a necessity.

1. Most offices now have processes that are linked to online connectivity, storage online, payment methods online. If you are working, you will need a smart phone to at least be able to access work-related documents or to do work processes,
2. Payment methods are now faster and a lot cater more to online transactions. Especially in a world ruled by credit, being able to buy and pay online has become essential to daily activity.
3. Being in contact or contactable is absolutely important whether this be by family, or work, or for freelance projects.

So when making your list of ‘must have’s', stop and think hard if a mobile phone really isn’t one of them

Smart Gadget Choices

There is no doubt these days that, to stay on top of things from friendships to work commitments, you have to have a gadget or two. That can be a daunting and expensive reality to face. It is a good thing there are ways to rationalize this reality and to trim down your would-be purchases.
Think first about use- specifically how and where you will use your gadget. Are you going to use it for socials or do you need to do heavy work on it? Do you need to be mobile or are you planning to do the bulk of your activity at home? This will help you decide between a desktop, laptop, notebook, net book, or a tablet. Then think about your need. Can you do most or all of your tasks with one or two gadgets, like a net book and an iPhone, instead of owning a shuffle, an iTouch, and iPhone, and a laptop? Finally consider payment; can you afford it and the subsequent maintenance?
Asking yourself these questions will help you make a smart gadget purchase.

Database manipulation

The database has been initialized, so now we get down to business of defining the fields in that database and include a field that we would call a foreign key which allows the establishment of the one to many relationship between the tables. This part of the process requires quite a bit of background of database creation, manipulation and handling. It also requires knowledge regarding the workings of data types. So assuming you do not have much knowledge in such areas do some more reading to give you a better understanding of what how and why they are there. The ROR developers might say that it is very easy to do and use ROR but without the background on logic formulation, data types and manipulation as well as database handling the rest of the posts which would tackle ever hardening topics and operations would be very difficult to make sense of.

Don’t get me wrong, we just want to make life easier for you and not have you not understanding anything at all.

def [](key)
if key.kind_of?(integer)
result = @Books[key]
else
result = @Books.find { |aBooks| key == sBooks.name}
end
return result
end
end

end
end

The use of the ‘find’ command in Ruby is simply a call to a function that is executed and it can be compared to a block call in many other languages such as Perl, C++ or Java.
