+ - Kawa 2.0 supports Scheme R7RS

Submitted by Per Bothner
Per Bothner (19354) writes "Kawa is a general-purpose Scheme-based programming language that runs on the Java platform. It combines the strengths of dynamic scripting languages (less boiler-plate, fast and easy start-up, a REPL, no required compilation step) with the strengths of traditional compiled languages (fast execution, static error detection, modularity, zero-overhead Java platform integration).

Version 2.0 was just released with many new features. Most notably is (almost) complete support for the latest Scheme specification, R7RS, which was ratified in late 2013. This LWN article contains a brief introduction to Kawa and why it is worth a look."

+ - Barnes & Noble fails to update Nook app in advance of Android 5.0

Submitted by tulare
tulare (244053) writes "If you read your eBooks on a Nexus device, plan on doing without reading anything purchased via the Nook bookstore for a while. According to comments made by NOOK on their Facebook page, they will be releasing a fixed version in a week or two.

This begs a couple of questions:
Why did BN miss this?
If BN decides the app business is too much trouble and walks away, what happens to the DRM-protected libraries of their customers?

This has happened before."

I understood the power transmission thing differently. I thought he wanted to resonate the capacitance of the Earth's atmosphere to transmit AC power. The reason that the idea didn't take off was that you can't meter the consumption. Anyone has access to siphon off the energy from the atmosphere. He had a solution that did not yield itself to a viable business model.

NASA Finds a Delaware-Sized Methane "Hot Spot" In the Southwest 213

Posted by samzenpus
from the it's-getting-hot-in-here dept.
merbs writes According to new satellite research from scientists at NASA and the University of Michigan this "hot spot" is "responsible for producing the largest concentration of the greenhouse gas methane seen over the United States—more than triple the standard ground-based estimate." It covers 2,500 square miles, about the size of Delaware. It is so big that scientists initially thought it was a mistake in their instruments. "We didn't focus on it because we weren't sure if it was a true signal or an instrument error," NASA's Christian Frankenberg said in a statement.

It includes clauses that can record your speech, and even track your keystrokes. Is this new touchy-feely Microsoft just fuelling the paranoid view that its in cahoots with The Man?"

Submitted by girlmad
girlmad (2404748) writes "Secret Cinema, the darling of quirky movie experiences, has seen exactly how frightening a bunch of angry hipsters can be after it cancelled the opening night of its latest show, Back to the Future. The short notice and lack of explanation from the 'immersive cinema experience' company led to a huge backlash on social media, with angry fans taking to Twitter and Facebook to share their frustrations at the handling of the whole thing. Cue much blaming of the Libyans and flux capacitor breakdowns."

Please let me know if I'm wrong, as it's certainly possible. What the proposal allows for is that say Netflix, or Youtube, or any other content provider that would utilize a lot of bandwidth, would be allowed to purchase direct physical lines to individual large ISPs for that ISP's customers instead of sending data over the Internet backbone. The end result would be a faster connection for that provider and those end users, for ultimately less cost.

So what we're dealing with here is a content provider that adds extra bandwidth to the Internet (albeit for a specific purpose), and pays for it, for the intended purpose of saving money for all parties involved while improving the end customer experience. Can someone please tell me why this is a problem? Or am I reading it incorrectly?

I do agree that from a technical point of view, the provider is purchasing a higher tier connection from the ISP for an improvement in throughput, but this in no way impacts any other service. I can envision the standard net neutrality argument that would allow an ISP to possibly extort a content provider, although I can't imagine why they would ever want to do so, considering peering agreements favor the consumer of data. Even so, tweaking the rules to disallow the restriction of data would make more sense than forbidding a willing provider to selectively choose to improve the experience for a specific group of customers above and beyond what is currently possible through the Internet for the same cost.

Dell has developed a mock-up of what such a device might look like in the future and it is all about panels, screens and glass, because the power provided on the back end means the design is unbounded by thermals and space."

girlmad (2404748) writes "Google has scored a major win on the back of Microsoft’s Windows XP support cut-off. The London Borough of Barking and Dagenham has begun moving all its employees over to Samsung Chromebooks and Chromeboxes ahead of the 8 April deadline. The council was previously running 3,500 Windows XP desktops and 800 XP laptops, and is currently in the process of retiring these in favour of around 2,000 Chromebooks and 300 Chromeboxes. It estimates the savings at around £400,000, no small change."

llebeel (2761081) writes "London Underground's "next generation" tube train could to do away with sardine like commutes. The body is working with potential suppliers for these trains on a regular basis to work out what they will look like and how they will solve some of the overcrowding problems in the Tube network due to its ever growing number of passengers.

One contender in the bidding to provide that next gen train is German electronics firm Siemens, who has built a "tube train of the future" mock-up, the Inspiro metro train, which rests at the Crystal in the Royal Victoria Dock in East London. If London Underground choose the Inspiro, passenger numbers will be increased by around 10 percent."
