What is Cross-Validation? In Machine Learning, Cross-validation is a resampling method used for model evaluation to avoid testing a model on the same dataset on which it was trained. This is a common mistake, especially that a separate testing dataset is not always available. However, this usually leads to inaccurate performance measures (as the model…
Computer science as a field requires curricular guidance, as new innovations are filtered into teaching its knowledge areas at a rapid pace. Furthermore, another trend is the growing number of students with different cultural backgrounds. These developments require taking into account both the differences in learning styles and teaching methods in practice in the development of curricular knowledge areas. In this paper, an intensive collaborative teaching concept, Code Camp, is utilized to illustrate the effect of learning styles on the success of a course. Code Camp teaching concept promotes collaborative learning and multiple skills and knowledge in a single course context. The results indicate that Code Camp as a concept is well liked, increases motivation to learn and is suitable for both intuitive and reflective learners. Furthermore, it appears to provide interesting creative challenges and pushes students to collaborate and work as a team. In particular, the concept also promotes intuition.
On May 8, 1828, Swiss businessman and social activist Henry Dunant was born. He is best known for the creation of the International Committee of the Red Cross in 1863. Also the 1864 Geneva Convention was based on Dunant's ideas. In 1901 he received the first Nobel Peace Prize together with Frédéric Passy.
Cross-Origin Resource Sharing (CORS) is a specification that enables a truly open access across domain-boundaries. With this site we want to support the adoption of CORS
The Limits of XMLHttpRequest
Ajax via XMLHttpRquest (XHR) has been revolutionizing the web, driving the web2.0 movement. While there are complaints, the technique is quite effective. However, it does have a severe limitation in that the requests can only be made to a server within the same-origin of the currently loaded page. This was implemented as a security measure, but it's a questionable one to take (see Security Outlook).
Enter COWS Ajax and many Possibilities become available. Allowing a connection to foreign sites can lead to the creation of a new breed of powerful tools and favelets. Instead of each site owner making their own tools, now a single author can make and distribute a cool tool or service that is easily installed on countless sites with the simple addition of one or two lines of code. It's extremely easy to install for a site owner, can provide extremely powerful apps to the users, and can provide extremely good branding or revenue for a tool creator.
