Crawl a website with scrapy - *.isBullsh.it In this article, we are going to see how to scrape information from a website, in particular, from all pages with a common URL pattern. We will see how to do that with Scrapy, a very powerful, and yet simple, scraping and web-crawling framework. For example, you might be interested in scraping information about each article of a blog, and store it information in a database. To achieve such a thing, we will see how to implement a simple spider using Scrapy, which will crawl the blog and store the extracted data into a MongoDB database. We will consider that you have a working MongoDB server, and that you have installed the pymongo and scrapy python packages, both installable with pip. If you have never toyed around with Scrapy, you should first read this short tutorial.
Digital learning resources // National Film and Sound Archive, Australia NFSA Digital Learning combines the former Screen Australia Digital Learning websites and NFSA’s online education resources. These content rich education websites feature thousands of video and audio clips available for streaming and downloading. Twelve Canoes A portrait of the history, culture and place of the Yolngu people. Mechanical Engineering Mechanical engineering is one of the broadest technical fields you can enter. As a result, this program is designed to provide you with a solid background in both mechanical and energy systems (and their respective components). To acquire competence in these areas, you will need a solid foundation in math and science, and will accordingly be required to complete a suite of pre-requisite courses in each of these ancillary disciplines. The Mechanical Engineering curriculum is divided into four sections: 100-level courses, 200-level courses, 300-level courses, and 400-level courses. Since the Saylor curriculum is self-directed, the numbering system used for course descriptors is designed to guide the student in the appropriate sequence of study.

Learning From Data - The Lectures Taught by Feynman Prize winner Professor Yaser Abu-Mostafa. The fundamental concepts and techniques are explained in detail. The focus of the lectures is real understanding, not just "knowing." Lectures use incremental viewgraphs (2853 in total) to simulate the pace of blackboard teaching. The 18 lectures (below) are available on different platforms: Here is the playlist on YouTube Lectures are available on iTunes U course app 10 Free Online Resources for Science Teachers One of the greatest ways technology can empower teachers is by helping them demonstrate concepts and by making it easier for students to learn through their own exploration and experimentation. Because science teachers are often called upon to teach topics that are too large, too small, happen too fast, happen too slowly, require equipment that is too expensive, or has the potential to blow up a laboratory, the Internet can be particularly helpful in assisting them convey a concept. Universities, non-profit organizations and scientists with free time have put an overwhelming number of resources for teaching science on the web. These are nine of our favorites.
