Microsoft Bets Its Future on a Reprogrammable Computer Chip
In December of 2010, Microsoft researcher Andrew Putnam had left Seattle for the holidays and returned home to Colorado Springs. Two days before Christmas, he still hadn’t started shopping. As he drove to the mall, his phone rang. It was Burger, his boss. Burger was going to meet with Bing execs right after the holiday, and he needed a design for hardware that could run Bing’s machine learning algorithms on FPGAs.

Putnam pulled into the nearest Starbucks and drew up the plans. It took him about five hours, and he still had time for shopping.

Burger, 47, and Putnam, 39, are both former academics. Burger spent nine years as a professor of computer science at the University of Texas, Austin, where he specialized in microprocessors and designed a new kind of chip called EDGE. Putnam had worked for five years as a researcher at the University of Washington, where he experimented with FPGAs, programmable chips that had been around for decades but were mostly used as a way of prototyping other processors. Burger brought Putnam to Microsoft in 2009, where they started exploring the idea that these chips could actually accelerate online services.

Meet PoisonTap, the $5 Tool That Ransacks Password-protected Computers
The perils of leaving computers unattended just got worse, thanks to a newly released exploit tool that takes only 30 seconds to install a privacy-invading backdoor, even when the machine is locked with a strong password.

PoisonTap, as the tool has been dubbed, runs freely available software on a $5/£4 Raspberry Pi Zero device. Once the payment card-sized computer is plugged into a computer's USB slot, it intercepts all unencrypted Web traffic, including any authentication cookies used to log in to private accounts. PoisonTap then sends that data to a server under the attacker's control. The hack also installs a backdoor that makes the owner's Web browser and local network remotely controllable by the attacker.

Pascal GPUs on All Fronts Push Nvidia to New Highs
Chip maker Nvidia was founded by people who loved gaming and who wanted to make better 3D graphics cards, and decades later, the company has become a force in computing, first in HPC and then in machine learning and now database acceleration. And it all works together, with gaming graphics providing the foundation on which Nvidia can build a considerable compute business, much as Intel’s PC business provided the foundation for its Xeon assault on the datacenter over the past two and a half decades.

At some point, Nvidia may not need an explicit link to PC graphics and gaming to have a self-sustaining datacenter compute business based on Tesla and GRID accelerator cards and now DGX-1 systems. Just like Intel arguably does not need the Core PC chip business to justify the existence of a very large and profitable Xeon server chip business. The two are evenly matched, in terms of profits, but the synergies are still there that allow Intel to do its process ramps on the smaller PC chips that have higher volumes and then build bigger Xeon chips that have lower volumes on a much more mature process.

Infographics: Operation Costs in CPU Clock Cycles
Whenever we need to optimise the code, we should profile it, plain and simple. However, sometimes it makes sense just to know ballpark numbers for relative costs of some popular operations, so you won’t do grossly inefficient things from the very beginning (and hopefully won’t need to profile the program later).

Tesla’s Autopilot Chip Supplier NVIDIA on New Self-driving System: ‘It’s Basically 5 Yrs Ahead and Coming in 2017’
NVIDIA reported its financial results for the last quarter yesterday and surprised Wall Street. The chip maker, which is now becoming an “AI company” according to its leadership, reported revenue of $2 billion on expectations of $1.7 billion and they also surpassed earnings expectations by a similar margin.

On a conference call with CEO Jen-Hsun Huang following the results, analysts were particularly interested in the company’s push in AI and the automotive industry, especially since Tesla’s started delivering every single one of its vehicles with NVIDIA’s Drive PX2 supercomputer.

This Old-Ass Commodore 64 Is Still Being Used to Run an Auto Shop in Poland
We need to learn a lesson about needless consumerism from this auto repair shop in Gdansk, Poland. Because it still uses a Commodore 64 to run its operations. Yes, the same Commodore 64 released 34 years ago that clocked in at 1 MHz and had 64 kilobytes of RAM. It came out in 1982, was discontinued in 1994, but it’s still used to run a freaking company in 2016. That’s awesome.

Hackers Could Break Into Your Monitor To Spy on You and Manipulate Your Pixels
We think of our monitors as passive entities. The computer sends them data, and they somehow—magically?—turn it into pixels which make words and pictures.

But what if that wasn’t the case? What if hackers could hijack our monitors and turn them against us?

As it turns out, that’s possible. A group of researchers has found a way to hack directly into the tiny computer that controls your monitor without getting into your actual computer, and both see the pixels displayed on the monitor—effectively spying on you—and also manipulate the pixels to display different images.

200 Chip Definitions Everyone Should Know
Given how important chips are to modern society EVERYONE should understand and appreciate how they are made. Every field has its own set of terms, jargon, and acronyms (engineers love acronyms!). As you would expect, chip design is no different. If you are new to chip design, it might take you a few days to read through the Wikipedia entries for each one of these 200 topics. If you are interested in actually building chips, you will need to master all 200 of them.

Why Networks Need ASICs
Tomorrow's networks are driving price and performance requirements that call for custom silicon, according to a senior manager for a company using ASICs.

Networks are in trouble. The volume of data, applications and transactions hitting data centers is increasing at an exponential pace. Add in predictions that by 2020 users will own as many as 25 connected devices and, according to Cisco, the Internet of Things will account for as many as 50 billion new IP-enabled devices and you can see a tsunami of traffic headed our way.

The WRT54GL: A 54Mbps Router from 2005 Still Makes Millions for Linksys
In a time when consumers routinely replace gadgets with new models after just two or three years, some products stand out for being built to last.

Witness the Linksys WRT54GL, the famous wireless router that came out in 2005 and is still for sale. At first glance, there seems to be little reason to buy the WRT54GL in the year 2016. It uses the 802.11g Wi-Fi standard, which has been surpassed by 802.11n and 802.11ac. It delivers data over the crowded 2.4GHz frequency band and is limited to speeds of 54Mbps. You can buy a new router—for less money—and get the benefit of modern standards, expansion into the 5GHz band, and data rates more than 20 times higher.

Car Speed Detector
Seventy-five? Really bro? But that got me thinking – could you document the speed of cars on a residential street to add support for police intervention?

Hmmm. I have a Raspberry Pi and a Pi Camera module. Ought to be able to use them to measure a car’s speed. What follows is my implementation of an application that records images with the speed of cars passing in front of the camera.

UK Surveillance Bill will Force Tech Companies to Disclose New Products Before They Launch
Internet, phone, and tech companies will have to inform the UK government of new products, services, and features ahead of their launch to ensure that they can be subject to surveillance.

The new policy is buried within a draft code of practice document as part of the UK government's efforts to reform its surveillance laws, and will impose obligations on tech companies operating in the country.

RISC-V: The Free and Open RISC Instruction Set Architecture
RISC-V (pronounced "risk-five") is a new instruction set architecture (ISA) that was originally designed to support computer architecture research and education and is now set to become a standard open architecture for industry implementations under the governance of the RISC-V Foundation. RISC-V was originally developed in the Computer Science Division of the EECS Department at the University of California, Berkeley.

Uncorrectable Freedom and Security Issues on x86 Platforms
It has recently come to my attention that many in the free software movement are unaware of a relatively new development on x86 platforms that permanently removes the ability to use these platforms without also continually executing signed, proprietary code at the highest possible privilege level. All post-2013 (AMD) and virtually all post-2009 (Intel) systems contain this mandatory technology, and therefore, by design, can never be converted to run using pure FOSS. Prior to these changes projects such as coreboot could be used to replace the boot firmware with a FOSS alternative.

X500 Evo Arrived
As some might already know, last year Loriano Pagni (know from the awesome custom MiniMig cases) designed a mini-itx case shaped in a way reminding the Amiga 500 named the X500 Plus case.

After a year and some months, the package reached my doorstep a couple of weeks ago! It was thrilling opening the package and seeing the final product for the first time.

How FPGAs work, and why you'll buy one
Will FPGA eventually become a must-have, or will its volume remain relatively low?

We'll try to answer this question below. In order to see how popular FPGAs could become, we'll need to discuss what FPGAs are. FPGAs are a programmable platform, but one designed by EEs for EEs rather than for programmers. So for many programmers, FPGAs are exciting yet mysterious; I hope our discussion will help demystify them.

CPU Backdoors
It’s generally accepted that any piece of software could be compromised with a backdoor. Prominent examples include the Sony/BMG installer, which had a backdoor built-in to allow Sony to keep users from copying the CD, which also allowed malicious third-parties to take over any machine with the software installed; the Samsung Galaxy, which has a backdoor that allowed the modem to access the device’s filesytem, which also allows anyone running a fake base station to access files on the device; and Lotus Notes, which had a backdoor which allowed encrypted files to be decrypted.
