What is a bad way to determine whether your software works?

Do you have to click through every single button on every single screen to make sure that something isn’t broken? And if it breaks, do you know what went wrong and where?

If you answered yes and then no, then you probably haven’t written unit tests for your code as most of these issue can be reduced.

Unit tests improve design and and ensures that as a developer, you are thinking about decoupled objects serving a single responsibility and thinking more along the lines of writing testable code.

I am not saying that Unit tests eliminates all bugs or issues. It just reduces them significantly.

What Unit Testing frameworks are there for us to use?

There are quite a couple as we can see from Wikipedia.

I just tend to use the Visual Studio unit tests.

Geohot, who is known for many reasons, says his still unnamed jailbreak will probably function on  iPad as well. In case this is correct it is no good news for Apple since their latest, forecasted, milestone hasnt even been released yet.

Rapidshare
Rapidshare United States on 4/18/2010 4:54 PM This document defines leading file share websites, their fundamentals and functionality, gives general overview of Rapidshare and its options, describes Rapidshare search engines, the way they work and how to make them help you search for files, when searching for files and folders on Rapidshare.

Prior to describing Rapidshare search engines, take a look at this general leading file share websites services overview. As other web surfers, you have undoubtedly heard about Rapidshare and similar websites, invented to help people easily share docs, vids, music, soft and other media and files over the web. Created by German webmasters many years ago, Rapidshare became world famous file share within a couple of years in the world, which led to creation of an .com version used by above 200 million people from 200 countries. Due to popularity of this fileshare, first Rapidshare search engines were presented on the Internet nearly 1 year ago. If you\'re in need of sharing vacation pictures with your friends and colleagues, if you need to spread some documents and files with your colleagues bypassing mass e-mail distribution, just use Rapidshare to help people quickly download all the files from any computer.

Other than this, you\'ve definitely came across plenty of blogs and forums providing links to media and other files over Rapidshare as well as Rapidshare search engines that help people finding files there. This way they save bandwidth and share necessary files among their visitors. So, as you can see Rapidshare is a very useful, world famous file share service that helps people, businesses and others quickly share content over the web.

At the same time, there is one unsatisfactory feature. Rapidshare will not allow you searching for content on Rapidshare. Despite of that you are sure that a necessary file is most likely hosted on Rapidshare and you can get it, you are unable to find it, due to the fact that they haven\'t got a search engine.

That is exactly where Rapidshare search engines become useful. Rapidshare search engines are akin to Google, Yahoo and other search engines with one important exception. They don\'t crawl the web - they index Rapidshare and other file share services, that\'s how you always get clean links without unnecessary garbage. Give Rapidshare search engine a try and you will definitely find all the files you need very quickly!

Well, let\'s take a look at major types of Rapidshare search engines available on the Internet. Essentially we can outline three basic classes: old-style, modern and developing rapidshare search engines. Basic search engines offer just basic services. Their pages usually contain only a search string. That\'s it. You type search term, hit the search button, get your results and download your file. Major disadvantage of this group of services is that they don\'t display files related to your keyword, they don\'t check the files for availibility and consistency and they don\'t index other websites, besides of Rapidshare. They provide only basic services, however, they\'re trash. Other type covers a bit more advanced Rapidshare search engines providing related keywords, check the files for availibility and consistency and give hints about related and related content. Again, they don\'t let you search on many other file share services and they won\'t provide you with many handy options of full-featured services. Now modern Rapidshare search egines are providing you a maximum of possible options covering many handy things and indexing almost all of the leading Internet file databases, including Rapidshare and its mirrors. As you can see it is questionless that you must find a advanced Rapidhsare search egnine to get all you need from this kind of sites.

If you want to share fresh pictures with your relatives and friends, if you need to send documents and files to your colleagues bypassing mass e-mail distribution, just use Rapidshare to let people quickly get all the files from any computer.

At this point, let\'s talk about general types of Rapidshare search engines available out there. Basically we can outline three typical variations: basic, advanced and full rapidshare search engines. Classic search engines offer only one service. Their pages usually contain a search string and a tag cloud. Nothing else. You type a keyword, hit the search button, get your results and try to download the necessary file. The most obvious lack of services like this is that they never show linked files, they never check the files for availibility and they fail to index other file shares, except for Rapidshare. They provide only basic services, but generally, they\'re simply outdated. Second type crawls several Rapidshare search engines providing related keywords, check the files for availibility and suggest likely and related files. But despite of this advantage, they don\'t let you search on other file share services and they won\'t give you all the features of top services. Now modern Rapidshare search egines are ready to offer you a maximum of services combining plenty of useful features and crawling almost all of the leading Internet file databases, including Rapidshare.com.
