Raspberry PI And Over-The-Counter Laser Can ‘Disable Self-Drive Car’

Jonathan Petit, the principal scientist at Security Innovation, has managed to disrupt the awareness programming in self-driving cars with a simple laser pen and pulse generator. The equipment is easily obtainable and requires a low-cost computer such as the Raspberry PI. Once combined with a laser pen, you can trick the car’s sensors into thinking there is a “ghostlike” object ahead which causes the vehicle to slow down. Mr Petit told tech magazine IEEE Spectrum that a vehicle could come to a complete halt if enough objects were detected.

“I can spoof thousands of objects and basically carry out a denial of service attack on the tracking system so it’s not able to track real objects,”
“I can take echoes of a fake car and put them at any location I want,”

This is a rather worrying revelation and raises questions about the safety of autonomous cars. Despite the huge investment into the driver-less technology, it seems bizarre that a $40 kit has the potential to create major incidents. Thankfully, Mr Petit and his research team have publicly published a paper on these concerns. As a result, the press coverage surrounding this revelation should help the self-driver car makers to tackle this issue head on and find a unbreakable fix.
Would you feel comfortable in a driver-less car?

Raspberry Pi launches new Zero, the £4 PC

The Raspberry Pi Zero, a £4 microcomputer, has launched today - and it's being bundled as a free cover-mount giveaway on The MagPi Magazine.









The Raspberry Pi Foundation has launched a new model of microcomputer, costing just £4 - cheap enough to be cover-mounted on the MagPi Magazine, a world-first.

When the Raspberry Pi launched, demand for the sub-£30 microcomputer took major websites offline for much of the day. While its single-core ARMv6 processor was already outdated, the promise of a fully-functional - if somewhat slow - computer the size of a credit card for so little money was alluring. Numerous revisions have launched in the years since including the cheaper Model A and faster ARMv7 quad-core Raspberry Pi 2, but today's launch is arguably the most exciting: the first Raspberry Pi to cost under £5.

Dubbed the Raspberry Pi Zero, the new model is based on the Model A+. There's the same Broadcom BCM2835 single-core system-on-chip (SoC) processor, albeit clocked at 1GHz by default rather than the usual 700MHz, beneath a 512MB memory module - the same quantity as found on the Model B+. The full-size ports, though, are gone: instead, you'll find a micro-USB power port, another micro-USB port for data, a mini-HDMI, and the usual micro-SD slot for storage. There's a full-size GPIO header, albeit one which arrives unpopulated, but little else: the CSI and DSI connectors, for cameras and flat-panel displays respectively, have been scrapped, while the composite video output is relegated to unpopulated solder points on the board.

Cutting down the parts has had two effects on the Pi Zero: it has reduced the size considerably, from something that would just about squeeze into an Altoids mint tin to something that fits with room to spare in a far smaller Smint tin; it has also dropped the cost, to the point where launch partners are offering the device for just £4 including VAT.

Impressively, the Foundation is also giving the device away. 10,000 copies of The MagPi, the official Raspberry Pi magazine, have been bundled with a cover-mounted Pi Zero and are available in high-street shops today, as well as from the official Raspberry Pi website for £5.99 - the first time in history a fully-functional computer has been cover-mounted on a print magazine. The magazine includes numerous tutorials and projects on using the device.

The Foundation has not yet announced how many Pi Zero units have been manufactured in total, but retailers are limiting purchases to one per customer - suggesting that supplies are limited.

Raspberry Pi Zero sells out in a day

The Raspberry Pi Foundation predicted demand for its new $5 Raspberry Pi Zero computer would "outstrip supply for the next little while", and they were right. Tens of thousands of units were made in preparation for the launch yesterday, and they've already sold out, as have issues of The MagPi (which included one for free).
Liz Upton, Raspberry Pi's head of communications said, "We were amazed at the rush on stores that happened as soon as we announced the release." More as being made as you read this, but Upton expects it will take some time before they can keep up.

Benchmarks Of The $5 Raspberry Pi Zero

For those curious about the performance of the $5 Raspberry Pi Zero, here are some benchmarks I've just finished up for this low-end, low-power ARM development board compared to other ARM, MIPS, and x86 hardware.

The Raspberry Pi Zero launched one week ago as the foundation's cheapest board yet (just $5 USD!) and also their smallest at about half the size of a Raspberry Pi Model A+. The Raspberry Pi Zero features a 1GHz single-core ARM processor, 512MB of RAM, mini HDMI and USB OTG ports, and a 40-pin header. There isn't any onboard Ethernet so you'll need to end up using a USB-based Ethernet or WiFi adapter. The Broadcom SoC in use by the Raspberry Pi Zero is a BCM2708.

For my initial testing of the Raspberry Pi Zero I was using the Debian-based Raspbian 8.0 with the Linux 4.1 kernel, LXDE desktop, and GCC 4.9.2 compiler.

There are two OpenBenchmarking.org result files that were used for this initial Raspberry Pi Zero benchmark comparison with the Phoronix Test Suite. First are some results comparing the Raspberry Pi Zero to the Raspberry Pi 2 (also using Raspbian 8.0) and then to high-end ARM boards: the NVIDIA Jetson TK1 and Jetson TX1.

The second set of results to share today from the Pi Zero are of the $5 ARM SBC compared to a i.MX6 quad-core Cortex-A9 system, an Intel Compute Stick with Atom Z3735, an Intel NUC with Celeron N2820 Bay Trail, and Intel NUC with Core i3 5010U Broadwell.

These are just the first of more Raspberry Pi benchmarks to come on Phoronix, including comparisons to other ARM boards.

Pre-installed malware on Raspberry Pi? They were asked to at least

It looks like some enterprising business people approached the Raspberry Pi Foundation with an odd business proposal, to pre-install their malware on the Raspberry Pi mini-computer.




In an email to the Foundation, a company, whose name was obviously redacted, was asking them to make available an exe file for installation (which wouldn't run on Linux anyway) in exchange for a sum of money for the amount of installations they detect.

This kind of tactic is surprising given the sheer audacity of asking a well-known organization, that prides itself on the many security applications of its minuscule box, outright to cheat its customers. It goes without saying that the Raspberry Pi Foundation didn't go along with their idea. It's even more hilarious that these peddlers of malware didn't seem to understand the platform being run on those devices. Maybe they'll ask Microsoft or Apple next?

Raspberry Pi gets experimental GPU acceleration, games now playable

The Raspberry Pi is a fantastic developer platform for all skill levels. The amount of amazing projects you can create is just staggering, but it's been somewhat limited by the meager processor under the hood. And the underused GPU. Experimental GPU acceleration has just been added to the latest release of Raspian, extending the possibilities immensely. Install at your own risk.

The Pi already had some fantastic gaming chops and was a natural choice for a small retro console. Those graphics you'd be running, from the SNES, NES, Genesis and Jaguar era's aren't terribly demanding. But opening up the GPU gives you more emulation possibilities. Not to mention the ability to play actual 3D games.

Not to mention all the other great sciency things you can now do more quickly with that otherwise unlocked GPU. It could potentially mean using a farm of Pi's (despite the relative inefficiency, but it has the cool factor) to compute novel things. They do warn, however, that installing the experimental driver could break other GPU functionality, and might even prevent the camera module from working properly. Not to mention messing up video playback support. But this is just the beginning stages of something quite nice that adds to the value of the minuscule devices.

Raspberry Pi 2 gets hardware accelerated OpenGL support

In a blog post concerning another new Raspian release an exciting new feature is touted - an experimental OpenGL driver for the desktop which uses the Raspberry Pi 2 GPU to provide hardware acceleration. The feature needs to be turned on, to switch from using the default software OpenGL renderer, however the "hardware-accelerated version is much faster, and makes some quite decent OpenGL games playable on the Pi," according to the blog.
The new Raspian release, available for download immediately, features a plethora of updated standard applications like Sonic Pi, Scratch, Mathematica and Node-RED. There are new library versions for WiringPi (for GPIO access), Python and Java. The update also brings along a number of updates and bug fixes to what is referred to as the 'Jessie image'. Importantly USB audio compatibility is improved, and the Main Menu editor now allows new menus to be created, and you can now overclock any RasPi version directly from the GUI Raspberry Pi Configuration and command-line raspi-config applications.

Behind the scenes of the incremental fixes and polish updates for Raspian the developers have been working on an experimental OpenGL driver for the desktop which uses the SoC's GPU to provide hardware acceleration. This driver is now shipping with the latest Raspian but has to be enabled (it's turned off by default). The driver is only compatible with the Raspberry Pi 2, due to memory limitations of other boards. While on the topic of possible problems, incompatibilities and other gotchas, it must be noted this is a beta driver and experimental. It is recommended only to be activated when you are going to use it and it may break some other RasPi features such as the Pi Camera and video playback support.

Video showing the difference in software and hardware accelerated OpenGL on the RasPi 2

As mentioned in the intro, this OpenGL driver is "much faster" than the software renderer usually used by the system. An OpenGL demo program such as GLXGears runs at about 23fps with incorrect colours and flickering on the software renderer but with the new hardware accelerated driver you can see it run at 60fps with the correct colours, flicker free (see video above). Various games tested by the developers also showed a marked improvement to smoothness and playability.

In other Raspberry Pi news, Samsung has ported the Tizen 3.0 OS to Raspberry Pi. Of course Samsung hopes RasPi users will develop more apps for its OS for use on the likes of mobile devices, wearables, TVs, and maker computer boards. PCWorld reports that developers are also contributing to port Tizen to the MIPS architecture.

Raspberry Pi 3 Breaks Cover In FCC Filing, Now With On-Board WiFi And Bluetooth

It's beginning to look like Raspberry Pi's developers are keen on releasing newer models a lot quicker than before. The second generation unit was released just last February, and already we're being treated to a tease of the third iteration. Well, by "tease", we mean that the FCC has a public filing now of all of the important bits of info - including photos.
At first glance the RPi 3 looks similar to the Raspberry Pi 2. With top-down images side-by-side, it took us some serious effort to spot the differences, and the differences we did see turned out to be some modification to the traces and filter cap arrangements on the board, not the ports, headers and slots.

The only thing the FCC didn't leak out is a table of official specs. But based on the fact that we know wireless has been added - by way of a Wi-Fi and Bluetooth module of some sort--and that the RPi 3 looks just like the RPi 2, it'd be easy to write this off as merely an RPi 2 with wireless capabilities tossed in. However, it'd be very unusual for those additions to bump the product's major version number, so we'd bet that there are more upgrades present than what the photos, mechanicals and information provided reveal.
At this point, until an official announcement is made, some of the details will be up-in-the-air. One thing we can't help but wonder: will the Raspberry Pi 3 be vulnerable to the Xenon Flash "Death Ray"? What we do know for sure is that the RPi 3 will continue to allow people to create some amazing things.

Need an example? Look no further than our DIY mini PC build right here.
