FBI Breaks into iPhone. The EFF Have Some Questions.

If the FBI used a vulnerability to get into the iPhone in the San Bernardino case, the VEP must apply, meaning that there should be a very strong bias in favor of informing Apple of the vulnerability. That would allow Apple to fix the flaw and protect the security of all its users. We look forward to seeing more transparency on this issue as well.

Apple mocks good hardware and poor people

At the beginning of Phil Schiller's iPad presentation, Schiller mentions that a lot of users come to iPad from PCs. "This is an amazing statistic," he says with a serious look before revealing that there are more than 600 million PCs in use that are over five years old. "This is really sad." Schiller continues. The audience laughs. "It really is," he says, and tries to continue before being interrupted by more laugher and applause. "These people could really benefit from an iPad Pro," he finishes.

Introducing the Raspberry Pi 3

The Raspberry Pi 3 Model B features a quad-core 64-bit ARM Cortex A53 clocked at 1.2 GHz. This puts the Pi 3 roughly 50% faster than the Pi 2. Compared to the Pi 2, the RAM remains the same - 1GB of LPDDR2-900 SDRAM, and the graphics capabilities, provided by the VideoCore IV GPU, are the same as they ever were. As the leaked FCC docs will tell you, the Pi 3 now includes on-board 802.11n WiFi and Bluetooth 4.0. WiFi, wireless keyboards, and wireless mice now work out of the box.

Inside the Volkswagen emissions cheating

In an interesting presentation [video link] at the 32nd Chaos Communication Congress (32C3) held at the end of December, Daniel Lange and Felix Domke gave a detailed look into the Volkswagen emissions scandal-from the technical side. Lange gave an overview of the industry, the testing regime, and the regulatory side in the first half, while Domke presented the results of his reverse-engineering effort on the code in the engine electronic control unit (ECU), as well as tests he ran on his own affected VW car. The presentation and accompanying slides [PDF] provide far more detail than has previously been available. Lange is a former BMW engineer who now runs his own consulting company. Domke is an independent security researcher who became curious about how the code inside his car was gaming the emissions testing.

Berkeley AI Materials

The Pac-Man projects were developed for UC Berkeley's introductory artificial intelligence course, CS 188. They apply an array of AI techniques to playing Pac-Man. However, these projects don't focus on building AI for video games. Instead, they teach foundational AI concepts, such as informed state-space search, probabilistic inference, and reinforcement learning. These concepts underly real-world application areas such as natural language processing, computer vision, and robotics.We designed these projects with three goals in mind. The projects allow students to visualize the results of the techniques they implement. They also contain code examples and clear directions, but do not force students to wade through undue amounts of scaffolding. Finally, Pac-Man provides a challenging problem environment that demands creative solutions; real-world AI problems are challenging, and Pac-Man is too.

Clean install of Windows 10

Windows 10 is an unusual release for Microsoft: if you have a licensed version of Windows 7 or 8/8.1, it will very easily upgrade to Windows 10--you don't even need to enter a licence key. Clean installations, however, are a bit trickier: you do need to enter a licence key, and your Windows 7/8 key probably won't work. Fortunately, if you're running Windows 7 or 8, and you really want to use your free Windows 10 licence key to perform a clean installation rather than upgrade, there is a solution. It's pretty convoluted, but it works.
