The drivers were there, but today's update to the Raspbian Linux distribution adds much-needed GUI tools to help you establish Bluetooth connections. Another cool addition is a new backup tool. There are other improvements as well including the mouse settings, and the ability to empty the wastebasket through right-clicking as seen below (yes, seriously). There is even a new shutdown dialog, something even casual users should notice.Official blog post here.

An anonymous reader writes: Humble Bundle announced a special "pay what you want" sale for four ebooks from No Starch Press, with proceeds going to the Electronic Frontier Foundation (or to the charity of your choice). This "hacker edition" sale includes two relatively new titles from 2015 -- "Automate the Boring Stuff with Python" and Violet Blue's "Smart Girl's Guide to Privacy," as well as "Hacking the Xbox: An Introduction to Reverse Engineering" by Andrew "bunnie" Huang, and "The Linux Command Line".

Hackers who are willing to pay "more than the average" -- currently $14.87 -- can also unlock a set of five more books, which includes "The Maker's Guide to the Zombie Apocalypse: Defend Your Base with Simple Circuits, Arduino, and Raspberry Pi". (This level also includes "Bitcoin for the Befuddled" and "Designing BSD Rootkits: An Introduction to Kernel Hacking".) And at the $15 level -- just 13 cents more -- four additional books are unlocked. "Practical Malware Analysis: The Hands-On Guide to Dissecting Malicious Software" is available at this level, as well as "Hacking: The Art of Exploitation" and "Black Hat Python."
Nice to see they've already sold 28,506 bundles, which are DRM-free and available in PDF, EPUB, and MOBI format. (I still remember Slashdot's 2012 interview with Make magazine's Andrew "bunnie" Huang, who Samzenpus described as "one of the most famous hardware and software hackers in the world.")

An anonymous reader quotes a report from BBC: Amazon has published an online guide explaining how to access its virtual assistant Alexa via a Raspberry Pi. The walkthrough includes access to the necessary app data and certificates in order to link the budget computer up to the tech giant's servers. Amazon says that users require at least the second-generation model, released in February 2015, as well as: a plug-in USB microphone, microSD card, ethernet cable, Wi-Fi wireless adapter, mouse, keyboard, and screen. The coding involved is limited to typing in sets of commands, but the guide explains the purpose of each one. Users also need to register for an Amazon Developer Account, which they can get for free.

Mickeycaskill writes with this news from TechWeek Europe: Every Year 7 student in England and Wales, Year 8 student in Northern Ireland and S1 student in Scotland will be handed, for free, a BBC micro:bit computer specially designed to help pupils learn to code. Micro:bits, which are smaller than the size of a credit card and can be hooked up to a mobile app or accessed via the Internet, will be delivered nationwide through schools and made available to home-schooled students over the course of the next few weeks. The students are able to keep their devices as their own, meaning they can work with the device for homework, in school holidays, and use it for more applications as their grasp on coding increases. The initiative follows on from the BBC's Micro programme that was introduced in the 1980s, and sees a partnership between the BBC and some of the world's most notable technology companies such as ARM, Microsoft, and Samsung. The computer will hope to emulate the Raspberry Pi, of which more than eight million have been sold. A BBC story explains a bit about the project's ambitions, and points out a few "bumps in the road"; originally, the hardware was to be in classrooms several months sooner. The BBC's own micro:bit page features more on programming the device, as well as many sample projects.

New submitter jimwelch writes: HDMI has shrunk to mini, then micro. USB has shrunk to mini, then micro. The wired Ethernet connector has not changed since 1988! On the Raspberry PI, it is the largest of the standardized connectors. Is it time to come up with a new version? What if, anything, would you like to see replace that suddenly clunky RJ-45 port? I rather like that (in theory) RJ-45 cables can't be easily dislodged, but at the same time dislike that its locking mechanism can be awfully fragile. And for that matter, I'm glad that on most of my computers so far there's been full-sized USB ports as well as full-size ethernet jacks.

An anonymous reader quotes an article on Kottke.org: Mathematicians have calculated pi out to more than 13 trillion decimal places, a calculation that took 208 days. NASA's Marc Rayman explains that in order to send out probes and slingshot them accurately throughout the solar system, NASA needs to use only 15 decimal places. Rayman explains, "The most distant spacecraft from Earth is Voyager 1. It is about 12.5 billion miles away. Let's say we have a circle with a radius of exactly that size (or 25 billion miles in diameter) and we want to calculate the circumference, which is pi times the radius times 2. Using pi rounded to the 15th decimal, as I gave above, that comes out to a little more than 78 billion miles. We don't need to be concerned here with exactly what the value is (you can multiply it out if you like) but rather what the error in the value is by not using more digits of pi. In other words, by cutting pi off at the 15th decimal point, we would calculate a circumference for that circle that is very slightly off. It turns out that our calculated circumference of the 25 billion mile diameter circle would be wrong by 1.5 inches. Think about that. We have a circle more than 78 billion miles around, and our calculation of that distance would be off by perhaps less than the length of your little finger."

szczys writes: We are surely in the age of single-board computers as the words "Raspberry Pi" sneak into the ranks of [a] household name. Many would have thought this impossible, but for hardware enthusiasts it has wide-reaching benefits as others clamor to enter the market. The most formidable challenge made so far is by the Hardkernel Odroid C2 which bests the Pi 3 on hardware, but not everything. Odroid C2 has the same cores, running faster with more RAM. It swaps out gigabit Ethernet for the Pi 3's somewhat unimpressive Wi-Fi chip. And it includes onboard eMMC (useful for faster booting) as well as an SD card slot. Odroid C2's hardware is clearly a better offering than Pi 3 for just $5 more (as we saw from the benchmarks last week), but that's not the entire story. It's further down Linux stream for a less mature distro, and has nowhere near the community support that has opened the Pi [up] to just about everyone. But it is the hardware geek's SBC with the layman's price tag and that's a very interesting indicator of where we are with low-cost computing.

Mickeycaskill writes: Western Digital has released a had drive optimized for the Raspberry Pi. The 314GB drive, released on Pi Day (3/14), costs $31.42 for a limited time and promises to be more reliable, power efficient and easier to use with the computer than other storage. The company, which also has a 1TB drive, says the unit has been designed to coordinate with the Pi's own power systems in order to minimize energy use without affecting the maximum data transfer rate on a USB connection. The Raspberry Pi Foundation says the new drive will stimulate the development of storage-hungry projects.

An anonymous reader writes: With the Raspberry Pi 3 now available, benchmarks have been done comparing the Raspberry Pi 3 to other ARM SBCs. The Raspberry Pi 3 was found to be a faster upgrade compared to the Raspberry Pi 2, but the ODROID-C2 is a much faster alternative. For only $5 more than the Raspberry Pi 3, it includes twice the amount of RAM, Gigabit Ethernet, and a faster SoC. The ODROID-C2 also has HDMI 2.0 and superior Ethernet while the Raspberry Pi 3 has an advantage of 802.11n WiFi. The ODROID-C2 also has a heatsink for ensuring the SoC doesn't get as toasty as the Raspberry Pi 3.

mikejuk writes: Mozilla has been clarifying some of its plans to convert the Firefox OS project into four IoT based projects. At a casual glance, this seems like a naive move that is doomed to failure. Project Link is a 'user agent' for the smart home, that helps the end user set preferences for device interaction, and automates those connections for the user in a secure environment. Next, Project Sensor Web will be a pilot project for crowdsourcing a pm2.5 sensor network. Project Smart Home is focused on bridging the gap in IoT smart home providers between completely boxed solutions like Apple HomeKit, and completely DIY solutions like Raspberry Pi. Finally, Project Vaani is a voice interface for IoT access, which Mozilla credits as the 'most natural way to interact with connected devices.' With Firefox losing market share and projects like Firefox OS, Thunderbird, Shumway, and Persona closing down, perhaps Mozilla should try and find its way back to core concerns. All four of the projects need significant AI expertise and a powerful cloud computing resource neither of which Mozilla is likely to be able to afford.

An anonymous reader writes: The original Raspberry Pi went on sale four years ago, and more than 8,000,000 units have shipped since then. Raspberry Pi computers are used in schools and universities, in factories and other industrial applications, in home automation and hobby projects, and much more. Today the Raspberry Pi 3 was announced, featuring a 64-bit quad-core ARMv8 CPU clocked at 1.2GHz, making it roughly 10x the speed of the original Pi 1. Many people will be pleased to hear that the Raspberry Pi 3 also features on-board Wi-Fi and Bluetooth, greatly improving the device's connectivity. The new device goes on sale today at the usual price of US $35. (Here's the official announcement itself.)

mikejuk writes: Details of the next in the family of the successful Raspberry Pi family have become available as part of FCC testing documents. The Pi 3 finally includes WiFi and Bluetooth/LE. Comparing the board with the Pi 2 it is clear that most of the electronics has stayed the same. A Raspberry Pi with built in WiFi and Bluetooth puts it directly in competition with the new Linux based Arduinos, Intel's Edison and its derivatives, and with the ESP8266 — a very low cost (about $2) but not well known WiFi board. And of course, it will be in competition with its own stablemates. If the Pi 3 is only a few dollars more than the Pi 2 then it will be the obvious first choice. This would effectively make the Pi Zero, at $5 with no networking, king of the low end and the Pi 3 the choice at the other end of the spectrum. Let's hope they make more than one or two before the launch because the $5 Pi Zero is still out of stock most places three months after being announced and it is annoying a lot of potential users.

An anonymous reader writes: On Thursday, Amazon announced the winners of its first-ever "AWS IoT Mega Contest," a competitive hardware hacking event held in conjunction with Hackster last month which drew nearly a thousand participants. First place went to an RFID, infrared, light and sound sensor system that gathers data about a sleeping baby and to a voice-controlled drone that sends radio signals using a Raspberry Pi board. "IoT is here now," posted an Amazon cloud evangelist, just four months after Amazon released their own Internet of Things platform. "People are building devices, sites, and applications that are sophisticated and useful."

An anonymous reader writes: With this month's Raspbian OS update, the Debian-based operating system for the Raspberry Pi ships experimental OpenGL driver support. This driver has been developed over the past two years by a former Intel developer with having a completely open and mainline DRM kernel driver and Mesa Gallium driver to open up the Pi as a replacement to the proprietary GPU driver.

mikejuk writes: The Pi Zero was supposed to be available from November 26, 2015. It is now the start of February and all of the stockists, including the Pi Swag Shop, are still showing out of stock. That's two whole months, and counting, of restricted supply which is more than an initial hiccup. Of course you would expect enough to be made available initially to meet the expected demand. The Pi sells something in the region of 200,000 per month so what do you think the initial run of the Pi Zero actually was? The answer is 20,000 units. Of which 10,000 were stuck to the cover of MagPi and "given away" leaving just 10,000 in the usual distribution channels. And yet Eben Upton, founder of the Raspberry Pi Foundation, commented: "You'd think we'd be used to it by now, but we're always amazed by the level of interest in new Raspberry Pi products," Well yes, you really would think that they might be used to it by now and perhaps even prepared for it. At the time of writing the Pi Zero is still out of stock and when it is briefly in stock customers are limited to one unit.
A victim of its own success, yes, but the real victims are the Raspberry Pi's competitors.

An anonymous reader writes: Contacting your internet provider to complain about slow browsing speeds is a tiresome chore which none of us enjoy, but one man has found a solution. He has configured a Raspberry Pi computer to automatically tweet a complaint to Comcast when his internet falls below 50Mbps, well below the 150Mbps he pays for. Wouldn't it be nice if ISPs wrote a rebate check each month to reflect the percentage of their promised throughput that was actually available?

An anonymous reader writes: I live in a Third World country with a more or less open Internet access. I'm thinking of learning robotics. I can access Github and other free software repositories, and I can read or watch online tutorials in English. My only problem is that we don't really have the money to buy robotics hardware. We can afford an Arduino or Raspberry Pi board but not the mechanical attachments. So is there any chance for me to learn robotics even if I don't have the hardware? Is it possible to program a robot using pure software simulation?

An anonymous reader writes: Every year politicians and business men meet at the World Economic Forum in the small mountain town of Davos, Switzerland to discuss various topics and create business deals. This year Quartz, an online newspaper/magazine sent a journalist to the forum tasked with writing a unconventional story about the forum: he was asked to monitor the private helicopter traffic coming in and out of Davos from transponder broadcast of ADS-B data. Using an $20 RTL-SDR dongle, Raspberry Pi and ADS-B collinear antenna they monitored the flights over Davos. From the data they were able to determine the flight paths that many helicopters took, the types of helicopters used and the most popular flight times.

MojoKid writes: The tiny single-board PC movement that's leading the Internet of Things (IoT) market is largely dominated by ARM-based processors, and for good reason — they're cheap, low power and capable. However, what if you prefer to work with the x86 architecture? JaguarBoard looks strikingly similar to Raspberry Pi, which is arguably the most popular single-board mini PC. But unlike Raspberry Pi, JaguarBoard allows users to develop for x86, courtesy of its Intel Atom Z3735G (Bay Trail) foundation. The chip is a quad-core part clocked at 1.33GHz to 1.83GHz with 2MB of L2 cache, offering a fair amount of horsepower for IoT applications. In addition to an Atom processor, JaguarBoard also boasts 1GB of DDR3L memory, 16GB of eMMC storage, three USB 2.0 ports, 10/100M LAN port, HDMI 1.4 output, SDIO 3.0 socket, two COM ports, four GPIO pins, and audio ports. It's an interesting device that you could use strictly as a mini PC for general purpose computing, as an embedded system, a learning or research tool, or for whatever DIY projects you can conjure up. It's not the only hobbyist-appropriate x86 board, but those specs are pretty good for $45.

The Linux 4.5 merge window has been open for the last two weeks; that means that the 4.5-rc1 kernel is expected to emerge, with the official kernel following in about eight weeks. An anonymous reader writes with this top-level list of changes to look for, from Phoronix: Linux 4.5 is set to bring many new features across the kernel's 20 million line code-base. Among the new/improved features are Raspberry Pi 2 support, open-source Raspberry Pi 3D support, NVIDIA Tegra X1 / Jetson TX1 support, an open-source Vivante graphics driver, AMDGPU PowerPlay/re-clocking support, Intel Kaby Lake enablement, a Logitech racing wheel driver, improvements for handling suspended USB devices, new F2FS file-system features, and better Xbox One controller handling.
