How to use the best free video converter/encoder available on all platforms, also known as... VLC. That's right, in addition to being a true Swiss army knife for video playback, VLC has a video-to-video (and audio) conversion functionality that is little known to the general public. Here is the procedure for using it:...

If you have ever checked the weather online, used the navigation function of your smartphone to find an on-duty pharmacy, or calculated the road expenses of your municipality, then you have already used "Open" Public Data. But maybe you didn't know it... For a long time, it was difficult (or even impossible) to access this information from the public authorities. This concept was born from the belief that the huge amount of information systematically collected by public administrations should be accessible to all citizens. In the late 2000s, states and their various services began to grant access to these resources to a greater number of users. The first government open data policies were introduced in 2009. Currently, more than 250 national and local governments, nearly 50 developed/developing countries, and institutions such as the World Bank and the United Nations have launched initiatives to release the data, and these are growing every year. Data is considered "open" if everyone can use, reuse and redistribute it freely, free of charge, for any purpose and without restrictions. Many data sets are published on government websites, but most of them are only meant to be viewed in isolation, and are not reusable for other purposes. Open data must be reusable, that is, downloadable in an open, software-readable format, and users must be legally permitted to reuse it....

What's your problem? You want to remove or extract a part of a video. You could download, install and/or buy some advanced editing software which has such feature (like Adobe Premiere Pro), but it takes a lot of time and energy, especially if you are working with several, long videos and the software has to decodes and re-encodes the files every time. The solution : FFmpeg....

The Selfie. Everyone knows everything about it... Or do they? How was it born? Where does it come from? Here I decided to dedicate an article to the Selfie story. I, a good disciple of the Web Lord, took my laptop pilgrim to write this article and preach the Good News of Technology to you, my dear readers......

This study is a comparative study of two particular types of visualization techniques in detail. We chose to study the map-based visualization and the bubble charts because they had been the most fascinating visualizations throughout this study. We are going to compare those two types on many factors. Defining the visualizations A thematic map is a type of map or chart especially designed to show a particular theme connected with a specific geographic area. These maps can portray physical, social, political, cultural, economic, sociological, agricultural, or any other aspects of a city, state, region, nation or continent....

This study is about the production and the description of some advanced visualization charts related to the higher education in South West Wales. Some real data had been made available to complete this task and the objective is to get some meaningful and interesting insight about the data. The tool used is IBM Many Eyes. It’s a web service that lets user upload data sets and can turn them into various visualizations. There were a lot of choices but only advanced visualization types (especially maps) had been highly recommended rather than basic charts. Further, graphs that show rises and falls over time had to be avoided as the provided data was not time oriented. So the five visualization types demonstrated here are block histograms, bubble charts, maps, matrix charts and tree maps....

How I draw the 2D characters Due to the nature of the drawing art, which is not really computer science related, I thought it was best to describe this process in another part right after the progress description. This work had been a full part of the project and even though it does not directly concern programming (before we get into animation), it is also a computer work involving a pen tablet and some image processing software (Adobe Photoshop). The following screenshots describe the steps in the drawing of one character (out of four)...

As I am writing this: There are 255 million websites and 152 million blogs online, 35 hours of video are uploaded to Youtube every single minute, 119 millions tweets are posted every day... It is estimated that a week's worth of the New York Times contains more information than a person was likely to come across in a life time in the 18th century....
