LOOK OUT, Brits – is that a Facebook LASER-GUN drone above us?

Zuckerberg's comms cruisers tested in UK skies

F8 2015 Facebook is still banging on about fleets of solar-powered, laser-firing drones that beam a glimpse of the internet to far-flung corners of the globe.

In a post on his Facebook blog on Thursday, CEO Mark Zuckerberg said one of his social network's unmanned "Aquila" craft has undertaken its first successful test flight. The machine took to the skies in the UK.

The website's cofounder said the drones will eventually be extremely large yet lightweight. The final design calls for a wingspan longer than that of a Boeing 737 – 95ft (29 metres) – while the whole thing weighing as much as a small car.

The solar-powered planes could be up in the air for "months at a time," Zuck says, and will operate at altitudes of 60,000-90,000 feet. In the process, the planes would act sorta like flying cell towers – sending and receiving data signals fired to and from ground stations. It's possible the machines will use infrared lasers to transfer packets of data through the skies, creating a high-altitude communications grid.

There's more on the proposed technology, here [PDF]. We've covered Zuck's drone dream previously:

"Aircraft like these will help connect the whole world because they can affordably serve the 10 per cent of the world's population that live in remote communities without existing internet infrastructure," Zuck wrote. And by "without existing internet infrastructure," he means, "without Facebook."

Speaking about the project at the F8 developer conference in San Francisco, California, on Thursday, FB chief technology officer Mike Schroepfer said the aim of the program was to develop internet service for remote areas without the massive costs of building towers and laying cable across huge stretches of uninhabited land.

"In dense urban areas it is economically feasible to recoup the massive capital investments telcos have to do to provide internet access," he said.

"As you move to more rural areas of the world, you just can't recoup those losses."

Neither exec gave dates for further tests or deployment, but Schroepfer said Facebook would be releasing more info on the project later this year. ®

    A British success story... what happens next?

    Industry talk is continuing to circulate regarding a possible public listing of the UK makers of the diminutive Raspberry Pi computer.

    Over the weekend, The Telegraph reported that a spring listing could be in the offing, with a valuation of more than £370m.

    Pi boss, Eben Upton, described the newspaper's article as "interesting" in an email to The Register today, before repeating that "we're always looking at ways to fund the future growth of the business, but the $45m we raised in September has taken some of the urgency out of that."

  • All change at JetBrains: Remote development now, new IDE previewed

    Security, collaboration, flexible working: Fleet does it all apparently

    JetBrains has introduced remote development for its range of IDEs as well as previewing a new IDE called Fleet, which will form the basis for fresh tools covering all major programming languages.

    JetBrains has a core IDE used for the IntelliJ IDEA Java tool as well other IDEs such as Android Studio, the official programming environment for Google Android, PyCharm for Python, Rider for C#, and so on. The IDEs run on the Java virtual machine (JVM) and are coded using Java and Kotlin, the latter being primarily a JVM language but with options for compiling to JavaScript or native code.

    Fleet is "both an IDE and a lightweight code editor," said the company in its product announcement, suggesting perhaps that it is feeling some pressure from the success of Microsoft's Visual Studio Code, which is an extensible code editor. Initial language support is for Java, Kotlin, Go, Python, Rust, and JavaScript, though other languages such as C# will follow. Again like VS Code, Fleet can run on a local machine or on a remote server. The new IDE uses technology developed for IntelliJ such as its code-processing engine for features such as code completion and refactoring.
