Synaptic

Devede is a product that allows the generation of discs of different video formats. It is very useful since it creates files and convert source files if necessary. In addition, has the ability to resize, and even to apply a filter of de-interlacing to remove those lines so annoying when we envision planes in constant motion. It is licensed as GPL, and then I pass a small basic tutorial. Installation. On their official website, have the option of lowering in .tar, or format package.

deb. Anyway, on my Ubuntu 9.10 (Karmic Koala), package is available in its version 3.13.1, so, through Synaptic is as easy as selecting it and install it. Boot. Applications / sound and Video, you’ll see the shortcut to DeVeDe. The first screen that appears is the following: start from the hypothesis of choose DivX / MPEG-4. According to Futurist, who has experience with these questions. Below the main screen appears to us: on the main screen, take into account: the menu file if we want to save the structure of the work you sent to DeVeDe to retrieve it at a later time, add to tell DeVeDe what files we want to include in the generation, the occupation for calculations if we go or not support destination and format by default. Important is also the advanced options section, which we’ll discuss later.

If we add a file and select the advanced options I recommend above all two things: the video format tab. In it we can decide what size we want for the target video. Be careful with the default option, since if it does not detect it well, the result will be wrong sizing. In my case, I happened to trying to convert a DVD video file to Divx and the result was with the elongated image, so to avoid problems, I recommend that you directly seleccioneis size target. Also be careful with (4: 3 or 16: 9) aspect ratio. Details can be found by clicking Petra Diamonds or emailing the administrator. The quality tab. In it you will find the way to eliminate in interlaced annoying of the videos to play on television. There are several options for deinterlacing, but which I have tried is the option of FFMpeg, and doing very well. If any have tested another, you can leave a comment. You have to think that these options apply to the current video, and not all together, so do not forget to configure them (those that you want to configure). And only you add all the videos to the list, giving the forward button and specify where you want to save the result. DeVeDe will generate it a .avi file for each of the videos included in the list.

Development of Software

1 – Introduction: At present the use of tools has become so essential to automate many processes. The flow of a flow test is specifically important in the development of software. It was crucial to investigate the use of tools to improve quality and efficiency of this flow. During the investigation will be revealed the importance of the tool to use, and its operation, through real examples of tests of a module. 2 – The tool JMeter JMeter is a free tool, it is also a Java tool that allows testing of performance and functional testing for Web applications. Load is a tool to carry out simulations on applications for Software. Java JMeter tool within the Jakarta project, which allows performance testing and functional testing on web applications and databases. There are a number of tools for testing free and paid (LoadRunner), but JMeter is known for his versatility, stability, and to be of use Free.

JMeter allows traditional web testing, but also allows you to test FTP, JDBC, JNDI, LDAP, SOAP / XML-RPC and Web Service (Beta). It also allows test execution distributed among different computers for performance testing. The JMeter shows the results of tests on a wide variety of reports and graphs. Also facilitates rapid identification of bottlenecks due to the excessive response time. All these tools can be used for testing under high load efficiency, but there are some that have advantages over the other, so are best to use during the tests in question.
