Actually, short breaks _don't_ improve productivity. Latest study (Harvard Business Review - http://hbr.org/2012/05/coffee-breaks-dont-boost-productivity-after-all/ar/1 - _do_ sign up and read the whole article, don't just read the headline) shows that productivity is, at best, indifferent to micro breaks and at worst, reduced significantly. Those breaks _do_ have some effect on the stress level of the employee, but that's not of the employer _immediate_ concern (though long-term employers should factor this into their calculations). Numbers and cases, or it isn't science. (oh, and 5 minutes of an 8 hours day is ~1%, not 0.2%).

...and Xmx should be 9999G...

Unfortunately, the Sun JVM (now Oracle main JVM) "array cells are consecutive in memory" blocks this. When the JVM reports "free memory = T" it must be able to allocate an array of size T. However, due to the aforementioned feature, this require the JVM to pre-allocate all the memory so it can reshuffle everything to be able to allocate that array in consecutive memory addresses. So why didn't they (Sun, now Oracle) drop this feature? Because it helps tremendously in signal and image processing, allow you to fine-tune memory-based optimizations and, usually, offers better array instantiation speed.

Typography On the Web Gets Different 378

bstender writes "Most major browsers — including the latest versions of Internet Explorer, Firefox, Safari, Chrome, and Opera — recognize a CSS rule known as @font-face. What that means, in brief, is that Web developers can now easily embed downloadable fonts in their pages. To see an example, load up Firefox 3.5 or Safari 4 and learn more. You'll see three new typefaces — Liza, Auto, and Dolly — used in the body text and headlines." No doubt the licensing issues are just as complex as the font nerd potential.

Cats "Exploit" Humans By Purring 503

An anonymous reader notes a BBC report on research recently published in the journal Current Biology, indicating that cats manipulate humans by adding a baby-like cry to their purring. "Cat owners may have suspected as much, but it seems our feline friends have found a way to manipulate us humans. Researchers at the University of Sussex have discovered that cats use a 'soliciting purr' to overpower their owners and garner attention and food. Unlike regular purring, this sound incorporates a 'cry,' with a similar frequency to a human baby's. The team said cats have 'tapped into' a human bias — producing a sound that humans find very difficult to ignore."

Google To Promote Web Speed On New Dev Site 106

CWmike writes "Google has created a Web site for developers that is focused exclusively on making Web applications, sites and browsers faster. The site will allow developers to submit ideas, suggestions and questions via a discussion forum and by using Google's Moderator tool. Google hopes developers will join it in improving core online technologies such as HTML and TCP/IP. For Google, a prime example of how Web performance can be enhanced is the development of HTML 5, which provides a major improvement in how Web applications process Javascript, Google believes. 'We're hoping the community will spend some time on the basic protocols of the Internet,' Google product manager Richard Rabbat said. 'There's quite a bit of optimization that can be done [in that area].'"

New Ads That Watch You 238

Pandanapper writes to tell us Yahoo is reporting that if you find yourself watching an ad on a video screen in a public venue, the ad may be watching you as well. "Small cameras can now be embedded in the screen or hidden around it, tracking who looks at the screen and for how long. The makers of the tracking systems say the software can determine the viewer's gender, approximate age range and, in some cases, ethnicity -- and can change the ads accordingly. That could mean razor ads for men, cosmetics ads for women and video-game ads for teens."

HP Pushes Open Source For Small Businesses 118

ruphus13 writes "HP finally begins to actively push open source in its products. From the post, 'HP has been quirky over the years when it comes to open source. It has been, traditionally, a company that supports open source — especially in larger enterprises... Wednesday, it announced two new open source products, geared to small businesses and educational institutions. HP plans on including its 'Mozilla Firefox for HP Virtual Solution' on more of its business class desktop PCs (to a total of seven models between the HP Compaq dc/dx lines in the US, eight models worldwide). Come December 15th, HP will also offer Novell's SUSE Linux Enterprise Desktop on its HP Compaq dc5850 model. The base SLED-equipped model will cost $519, and features the usual open source suspects for the small business setting — OpenOffice, and mail clients such as Evolution.'"

Comment Animations and 3D (Score 3, Informative) 295

In my university days, I understood a lot of calculus by visualizing an animated sequence (mean value theorem, limits, derivatives...). Animation is a great tool for these things. Same goes for numerical analysis.
Also (from the same days), linear algebra can be (often / sometimes) simplified to a 2d / 3d projection which can be displayed easily by a computer. Forget that you CAN'T draw in 3D or can't animate in 2D on the board - the computer can.
And of course - physics, chemistry, geography, history - omg, history would be so cool to learn with a projector, if done correctly (not just clips - diagrams, arrows on the world map describing population movements, pressures, wars) - all of the "real world" sciences are much more fun when working in the real world. Even political science (if your school offers it) can enjoy the benefits of a projector, even if only as a video machine (watching Marting Luther King Jr. making his speech for example).
However - I don't think that a projector is a "magic wand". It conforms to the equation "invest more time, reap more results". If you invest the proper amount of time preparing good material (and not only video clips), your students would enjoy it immensely.
Just my 2 bits.

An anonymous reader writes "Emotiv Systems today unveiled a brain/computer interface system with a helmet and software applications at the Game Developers Conference in San Francisco.
