Java SE 7 Collections-Related APIs and Developer Guides The collections framework is a unified architecture for representing and manipulating collections, enabling them to be manipulated independently of the details of their representation. It reduces programming effort while increasing performance. It enables interoperability among unrelated APIs, reduces effort in designing and learning new APIs, and fosters software reuse. The Algorithm: Idiom of Modern Science by Bernard Chazelle hen the great Dane of 20th century physics, Niels Bohr, was not busy chewing on a juicy morsel of quantum mechanics, he was known to yap away witticisms worthy of Yogi Berra. The classic Bohrism “Prediction is difficult, especially about the future” alas came too late to save Lord Kelvin. Just as physics was set to debut in Einstein's own production of Extreme Makeover, Kelvin judged the time ripe to pen the field's obituary: “There is nothing new to be discovered in physics now.”
10 Usability Tips Based on Research Studies We hear plenty usability tips and techniques from an incalculable number of sources. Many of the ones we take seriously have sound logic, but it’s even more validating when we find actual data and reports to back up their theories and conjectures. This article discusses usability findings of research results such as eye-tracking studies, reports, analytics, and usability surveys pertaining to website usability and improvements. You’ll discover that many of these usability tips will be common sense but are further supported with numbers; however, some might surprise you and change your outlook on your current design processes. 1.
Reverse Polish Notation Reverse Polish Notation is a way of expressing arithmetic expressions that avoids the use of brackets to define priorities for evaluation of operators. In ordinary notation, one might write and the brackets tell us that we have to add 3 to 5, then subtract 2 from 7, and multiply the two results together. In RPN, the numbers and operators are listed one after another, and an operator always acts on the most recent numbers in the list.

Not to worry, the elves of the Internet are busy at work, creating everything from magical little algorithms that automatically execute basic tasks to sophisticated utility apps that run in the background, taking care of all the minutiae in your daily life. Forget about hiring a personal assistant, you can “hire” off-the-shelf algorithms and digital apps that do all the heavy lifting for you.

Introduction During hard times sooner or later everyone runs out of soap. Color management In digital imaging systems, color management is the controlled conversion between the color representations of various devices, such as image scanners, digital cameras, monitors, TV screens, film printers, computer printers, offset presses, and corresponding media. The primary goal of color management is to obtain a good match across color devices; for example, the colors of one frame of a video should appear the same on a computer LCD monitor, on a plasma TV screen, and as a printed poster. Color management helps to achieve the same appearance on all of these devices, provided the devices are capable of delivering the needed color intensities.
Artificial Intelligence This is an Archived Course EdX keeps courses open for enrollment after they end to allow learners to explore content and continue learning. All features and materials may not be all available. Check back often to see when new course start dates are announced. Artificial intelligence is already all around you, from web search to video games. » A Speculative Post on the Idea of Algorithmic Authority Clay Shirky Jack Balkin invited me to be on a panel yesterday at Yale’s Information Society Project conference, Journalism & The New Media Ecology, and I used my remarks to observe that one of the things up for grabs in the current news environment is the nature of authority. In particular, I noted that people trust new classes of aggregators and filters, whether Google or Twitter or Wikipedia (in its ‘breaking news’ mode.) I called this tendency algorithmic authority.
Five Minute Upgrade – Making Your Design Pop 1. Brighten Colors If you have a design that you just feel isn’t anything special – stop – crank up the color intensity – then reevaluate. Saturation plays a big role as far as mood goes. If you ever feel like you’re lacking inspiration when it comes to color schemes there are some great online tools, not to mention our own color series. 2.

Johannes Knabe (firstname.lastname@example.org) My Homepage is Why is quicksort better than other sorting algorithms in practice? - Computer Science Stack Exchange Under what conditions is a specific sorting algorithm actually the fastest one? 1) When implemented in a parallel way in hardware, does it need to have a reasonably low latency while requiring as few gates as possible? Yes -> use a bitonic sorter or Batcher odd-even mergesort, latency is and the number of comparators and multiplexers is . 2) How many different values can each element have? Cans every possible value have assigned a unique place in memory or cache Yes -> use count sort or radix sort, those usually have a linear runtime of (count sort) or (bucket sort) but slow down for a large number of different values, as and .
