robots.net - DARPA Plans Long Range Ship-launched UAVs

"It's like having a falcon return to the arm of any person equipped to receive it, instead of to the same static perch every time. About 98 percent of the world's land area lies within 900 nautical miles of ocean coastlines.

This is cross-posted from the new home of the Ocean of Awareness blog. ] The latest version of Marpa takes parsing "whipitupitude" one step further. You can now go straight from a BNF description of your language, and an input string, to an abstract syntax tree (AST).

Only 11 percent of all engineers in the U.S. are women, according to Department of Labor. The situation is a bit better among computer programmers, but not much. Women account for only 26 percent of all American coders. There are any number of reason for this, but we may have overlooked one.

Of course, the original docs are written in pod, and I would really like to distribute the translation with PDL itself. However, Vera has not expressed any interest in distributing these docs as pod, possibly because she (he?) would actually like to drive some viewers to his (her?) site.

This is an attempt to succinctly list all the different problems perceived with CPAN, and give them a name. No attempt at proposing solutions, or structuring a taxonomy / priority list, but data gathering. Following Brendan's post on the four major problems with CPAN, and other posts recently, I've been thinking a lot about the general topic, and clearly so have many others.

We are excited to announce our stellar lineup of guest keynote speakers for Imagine 2013! They are all masters of their art and leaders in their industries. They will offer the Imagine audience a range of fresh perspectives on topics both within and beyond commerce.

We are excited to announce that the new Arduino GSM Shield is ready to be shipped allowing Arduino boards (Uno, MEGA and Leonardo) to explore the wonders of adding a GPRS/GSM connection to interactive projects.

We've been able to aid the body's own repair of damaged bones for a relatively long time, but now we're ready to use 3D-printing to completely replace damaged bone. Earlier this week, 75% of a patient's skull was successfully replaced with 3D-printed material, and this is just the beginning.

Factor in the one-year on-site warranty and a chassis that is under 1-inch and 5 lbs and this is a whole lot of laptop for just $299.99 (with free shipping). It may not quite get us geeks all worked up, but the value in this machine is nearly unparalleled.

CodePlex - Open Source Project Hosting

Microsoft's open source project hosting web site. You can use CodePlex to find open source software or create new projects to share with the world.

Node 0.10 is about to be released - the next stable version of Node. The most major change is the new streams API, which is designed to overcome some of the limitations found in previous versions. For a summary of the issues with streams in Node 0.8 and the new API, see: A New Streaming API for Node v0.10.

Monday, March 11, 2013 at 9:51AM We talked about 42 Monster Problems That Attack As Loads Increase. And in The Aggregation Collection we talked about the value of prioritizing work and making smart queues as a way of absorbing and not reflecting traffic spikes.

PrePAN had been working on my private server. oalders, the founder of metacpan, referred to PrePAN in his blog post, so I made up my mind to move the site to AWS to ensure stability.

NASA unveiled an Exploration Design Challenge on Monday to give students from kindergarten through 12th grade the opportunity to play a unique role in the future of human spaceflight. The innovative educational opportunity was announced in a special event at NASA's Johnson Space Center in Houston.

Researchers in the United Kingdom have found algae-like fossils in meteorite fragments that landed in Sri Lanka last year. This is the strongest evidence yet of cometary panspermia -- that life on Earth began when a meteorite containing simple organisms landed here, billions of years ago.

Node v0.10.0 (Stable)

The fs.WriteStream throughput increases considerably, for most workloads. As the size of the chunk goes up, the speed is limited by the underlying system and the cost of string conversion, so v0.8 and v0.10 converge. But for smaller chunk sizes (like you'd be more likely to see in real applications), v0.10 is a significant improvement.

Researchers have developed a cloud-computing platform for robots. The platform allows robots connected to the Internet to directly access the powerful computational, storage, and communications infrastructure of modern data centers - the giant server farms behind the likes of Google, Facebook, and Amazon - for robotics tasks and robot learning.

Code.org recently made a splash with its high-profile supporters - everyone from Bill Gates to Snoop Dogg have offered up their support for Code.org's premise: that everyone should learn to code. While Code.org's goals are admirable, the movie above spends near zero time talking about what might be the most important part of the equation: computer science teachers.

JavaScript FTW: Episode 2: Classes and Inheritance (and why it matters!)

As we discussed last time, if we have code that's disorganized and difficult to debug, coding performance and scalability optimizations becomes moot. However, being explicit with your code not only makes your life easier, but actually makes your code faster (say whaaaaaaaat?). We have to remember that JavaScript isn't like most other languages.

Version 1.1 is virtually a re-write from the ground up. Not only is it easier to configure than 1.0 and better conforms to Spring MVC expections for the transition to Spring 3.2, but the biggest change in the internals of Spring Data REST is that it now supports other types of Spring Data repository implementations beyond just JPA.
