A number of years ago I worked on a project that required extensive manipulation of digital waveforms; the waveforms were stored in double precision floating point vectors (or arrays if you prefer). We quickly discovered that even when we compiled the programs we were not getting the speed required because of the loops needed to step through the entire vector. Not having any direct vector oriented operators such as those available in APL we decided to create our own subroutines that we could pass a vector to and have the operation done quickly in machine language.

Of course we gained a lot of speed but did get the downside of being tied to a particular hardware processor without reprogramming the assemble language code. But… notice how tight the RESET: loop is (three instructions) used in the sample program below… sweet!

Viruses are a real concern for the technology world. Since the introduction of spyware and adware; viruses have become a bigger danger and threat to many computer systems and networks. Protecting your computer is important but more importantly knowing how to protect and remove those unwanted viruses is essential. Virus removal is no piece of cake which makes these annoying little viruses a real headache for the user and harmful to your computer.

Viruses are growing in numbers every day and leave a reign of terror wherever they visit. With so many viruses infection the information highways, it can be somewhat intimidating to the end users. The most common method of virus infection is through email attachments or downloads off the internet. It is important to know who and where information is being obtained and thoroughly checking it for viruses before opening or running on the computer.

In today's world, Internet is clearly the easiest, fastest and the most effective medium for communication. And, as the technology grows, it is deemed to get only better.

So, as the internet expands, the demand for good web designs and web designers is also rising by the day. Almost everyone wants a presence on the internet. And if you add the social media (also known as new media) angle to it, the opportunities start piling up even further - there are blogs, forums and other social media venues that are being created and used every minute.

Many older languages, like C and Pascal, were procedural languages. Procedures (also called functions) were blocks of code that were part of a module or application. Procedures passed parameters (primitive data types like integers, characters, strings, and floating point numbers). Code was treated separately to data. You had to pass around data structures, and procedures could easily modify their contents. This was a source of problems, as parts of a program could have unforeseen effects in other parts. Tracking down which procedure was at fault wasted a great deal of time and effort, particularly with large programs. You are reading the right article if it's computer programming help that you seek.

When times get tough and money is tight, people often put off buying new appliances - washers, dryers, toasters, TVs - and either fix the ones they have or buy a used or refurbished one. And the fact is, computers are appliances, too, sometimes the most popular ones of all, since they are now our “windows to the world,” as well as being the devices that everyone in every profession uses for work and people everywhere use for their entertainment.

Computer makers and big retailers have a big incentive to sell the “new and improved” message with every advance, big or small, in computing technology. But the fact is, not everyone needs the latest and greatest, and millions of people can do everything they need to do on models that are one, two or even five years old. How do you know what to buy? How do you go about choosing between a new or used computer?

A career in music could be rewarding for the talented amongst us. At a school of music, students are afforded the opportunity to sharpen their skills and get practical experience to help them build their career.

Schools of music are available the world over, of which the famed London Music School is probably the best-known school of music in all of Europe. Situated in Central London, The London Music School offers contemporary courses in sound engineering and music and audio technology. Being one of the older music schools, it has been the leading school of music for over 20 years.

In conjunction with further education for musicians looking to further their careers, the London Music School also offers courses for the enjoyment of those who simply love music.

Many times it seems that choosing the right type of treadmill is more a trial and error process than anything else. If this describes your experiences when purchasing exercise equipment it could be because you are not doing enough homework before making your decision. After all, if you don't know what features to look for then it is easy to fall madly in love with the first “glammed up,” hot looking treadmill that you see.

The thing about these fitness products is that you really have to look beyond that superficial beauty and find out some particulars about the features that make or break them. You also need to consider which special attributes of treadmills are the ones that are most important to you and your fitness goals.
