Awesome background images without compromising performance

It looks great! But, we’re talking a 500k+ monster when cropped out of the Photoshop comp at a width of 1280px. The design is final and you don’t want to slow down the site. What should you do? How about you keep that awesome huge image and maximize your site's performance. Here are three techniques you can use to keep the design and performance budget on point when it comes to large background images. Technique 1 - Compress It! Upload your image to a free online compression tool like Using a tool like this may be all you need to save your performance budget. For example - I took a 1280px-wide beach image (which I will be using later in this article) I downloaded at from 886k down to 238k, which is an enormous savings. Enter picturefill. Technique 2 - Use picturefill Picturefill is a javascript polyfill for the picture element and the emerging srcset and size attributes. Related article: Image tags vs CSS background images.

Algorithms: Design and Analysis, Part 1 - Stanford University

You'll learn the divide-and-conquer design paradigm, with applications to fast sorting, searching, and multiplication. You'll learn several blazingly fast primitives for computing on graphs, such as how to compute connectivity information and shortest paths. Finally, we'll study how allowing the computer to "flip coins" can lead to elegant and practical algorithms and data structures. Learn the answers to questions such as: How do data structures like heaps, hash tables, bloom filters, and balanced search trees actually work, anyway?

Aho/Ullman Foundations of Computer Science

H. Freeman. You are welcome to use it if you like. We believed in 1992 it was the way to introduce theory in Computer Science, and we believe that today. Automata - Stanford University. About the Course I am pleased to be able to offer free over the Internet a course on Automata Theory, based on the material I have taught periodically at Stanford in the course CS154.

Participants have access to screencast lecture videos, are given quiz questions, assignments and exams, receive regular feedback on progress, and can participate in a discussion forum. Those who successfully complete the course will receive a statement of accomplishment. You will need a decent Internet connection for accessing course materials, but should be able to watch the videos on your smartphone. The course covers four broad areas: (1) Finite automata and regular expressions, (2) Context-free grammars, (3) Turing machines and decidability, and (4) the theory of intractability, or NP-complete problems.Why Study Automata Theory?
