Book Review: Drush For Developers, 2nd Edition

Tue, 31 Mar 2015 18:03:00

Michael Ross writes As with any content management system, building a website using Drupal typically requires extensive use of its administrative interface, as one navigates through its menus, fills out its forms, and reads the admin pages and notifications — or barely skims them, as they have likely been seen by the site builder countless times before. With the aim of avoiding this tedium, speeding up the process, and making it more programmatic, members of the Drupal community created a "shell" program, Drush, which allows one to perform most of these tasks on the command line. At this time, there is only one current print book that covers this tool, Drush for Developers, Second Edition, which is ostensibly an update of its predecessor, Drush User's Guide. Read below for the rest of Michael's review.

Microsoft Considered Giving Away Original Xbox

Tue, 31 Mar 2015 17:14:00

donniebaseball23 writes While the term 'Xbox' is firmly implanted in every gamer's mind today, when Microsoft first set out to launch a console in 2001, people weren't sure what to expect and Microsoft clearly wasn't sure what approach to take to the market. As Xbox co-creator Seamus Blackley explained, "In the early days of Xbox, especially before we had figured out how to get greenlit for the project as a pure game console, everybody and their brother who saw the new project starting tried to come in and say it should be free, say it should be forced to run Windows after some period of time." Blackley added that other ideas were pushed around at Microsoft too, like Microsoft should just gobble up Nintendo. "Just name it, name a bad idea and it was something we had to deal with," he said.

Developer of 'Banished' Develops His Own Shading Language

Tue, 31 Mar 2015 17:00:00

jones_supa writes Luke Hodorowicz, the hard-working developer behind the townbuilding strategy computer game Banished, has designed a novel GPU shading language and written a compiler for it. The language has been christened 'Shining Rock Shading Language' (SRSL) and it outputs the program in several other shading languages. The first goal for the language was to treat the vertex, fragment and geometry shader as a single program. The language sees the graphics pipeline as a stream of data, followed by some code, which outputs a stream of data, and then more code runs, and another stream of data is output. Body text of the shaders is very C-like and should be understood easily coming from other shading languages. SRSL has all the intrinsic functions you would expect from HLSL or GLSL. All types are HLSL-style. Loops and conditionals are available, but switch statements and global variables are seen redundant and not implemented. Luke's blog post tells more about the details of the language, complemented with examples.

Why America's Obsession With STEM Education Is Dangerous

Tue, 31 Mar 2015 16:36:00

HughPickens.com writes According to an op-ed by Fareed Zakaria in the Washington Post, if Americans are united in any conviction these days, it is that we urgently need to shift the country's education toward the teaching of specific, technical skills, expand STEM courses (science, technology, engineering and math) and deemphasize the humanities. "It is the only way, we are told, to ensure that Americans survive in an age defined by technology and shaped by global competition. The stakes could not be higher." But according to Zakaria the dismissal of broad-based learning, however, comes from a fundamental misreading of the facts — and puts America on a dangerously narrow path for the future. As Steve Jobs once explained "it's in Apple's DNA that technology alone is not enough — that it's technology married with liberal arts, married with the humanities, that yields us the result that makes our hearts sing." Zakaria says that no matter how strong your math and science skills are, you still need to know how to learn, think and even write and cites Jeff Bezos' insistence that writing a memo that makes sense is an even more important skill to master. "Full sentences are harder to write," says Bezos. "They have verbs. The paragraphs have topic sentences. There is no way to write a six-page, narratively structured memo and not have clear thinking." "This doesn't in any way detract from the need for training in technology," concludes Zakaria, "but it does suggest that as we work with computers (which is really the future of all work), the most valuable skills will be the ones that are uniquely human, that computers cannot quite figure out — yet. And for those jobs, and that life, you could not do better than to follow your passion, engage with a breadth of material in both science and the humanities, and perhaps above all, study the human condition."

Cetaceans Able To Focus Sound For Echolocation

Tue, 31 Mar 2015 15:24:00

Rambo Tribble writes A recent study from Denmark has determined that porpoises, dolphins and whales can focus the sounds they make, described as "clicks and buzzes", when hunting. This appears to exceed even the capabilities of bats. One researcher described the ability as, "like adjusting a flashlight." The BBC offers approachable, and illustrated coverage.
