Stanford scientists have developed a manganese-hydrogen battery that could fill a missing piece in the nation’s energy puzzle by storing wind and solar energy for when it is needed, lessening the need to burn carbon-emitting fossil fuels.
Helium-filled hard drives attempt to cut down on friction, leading to better performance. We’ve crunched the numbers: how do they actually perform?
It has become clear that storing secrets in computers is hard. The best demo to the world that storing secrets on “online” computers is hard and sometimes devastating, is the large amounts of cryptocurrency theft due to critical keys being in memory of systems directly or indirectly connected to the internet.

NVIDIA Tesla V100 GPUs are now available in beta on Compute Engine and GKE, and NVIDIA Tesla P100 GPUs are now GA.
I am very excited to announce details of the first homemade integrated circuit and share the journey that this project has taken me on over the past year. I hope that my success will inspire others and help start a revolution in home chip fabrication. When I set out on this project I had no idea of what I had gotten…
Less is exponentially more – Rob Pike Smart phones are useful, but they are also incredibly addictive, and that addiction is at the epicenter of Silicon Valley’s effort to grab an ever-increasing percentage of our minds. If a substance or behavior controls us, it becomes our master, and that just won’t do. For the…
Yesterday, during OsmoDevCon 2018, Steve Markgraf released osmo-fl2k, a new Osmocom member project which enables the use of FL2000 USB-VGA adapters as ultra-low-cost SDR transmitters. How does it wor
Last year Purism contacted me after they read on the Pepper&Carrot blog that my laptop has been stolen in the burglary of my house. At that time, they proposed me to contribute to my Pepper&Carrot project by sending me a shiny new Librem13 laptop. So, since October 2017 I have this laptop with me and because I saw a…
MIT engineers have developed a scalable manufacturing process that spools out strips of graphene for use in ultrathin membranes.
Darwin: a genomics co-processor provides up to 15,000x acceleration on long read assembly Turakhia et al., ASPLOS’18 With the slow demise of Moore’s law, hardware accelerators are needed to m…
I've had a long history playing around with Raspberry Pis and other Single Board Computers (SBCs); from building a cluster of Raspberry Pis to run Drupal, to building a distributed home temperature monitoring system with Raspberry Pis, I've spent a good deal of time testing the limits of an SBC, and also finding ways…
Aiming for a 10 year life-cycle for smartphones
Introduction In my last post, I discussed the process of building my Magic Leap One (ML1) view simulator model (hereafter referred to as “model”), and now I would like to show you what the view of …
Cloudflare's jpegtran implementation was optimized for Intel CPUs. Now that we intend to integrate ARMv8 processors, new optimizations for those are required.
Back in 2015, I wrote a popular post comparing the performance of a number of microSD cards when used with the Raspberry Pi. In the intervening three years, the marketplace hasn't changed a ton, but there have been two new revisions to the Raspberry Pi (the model 3 B and just-released model 3 B+). In that article, I…
How low we can Go and still do something useful? I recently bought this ridiculously cheap board: I bought it for three reasons. First, I have never dealt (as a programmer) with STM32F0 series. Second, the STM32F10x series is getting old. MCUs belonging to the STM32F0 family are just as cheap if not cheaper and has…
As seen on Hackaday! There’s always some electronics topic that I end up focusing all my efforts on (at least for a certain time), and that topic is now eMMC NAND Flash memory. Overview eMMC …
Move over, Sennheiser. Make yourself scarce, Bose. Here comes the ultimate Hi-Fi solution for your living room: The Commodore 64! I s it sa...
Tiny device opens the door to displays that would be bright when turned on but see-through when turned off -- or in futuristic applications such as light-emitting tattoos
Have you ever wondered how your computer knows all the characteristics of your monitor— the supported resolutions, the model, and even the...
Typically when collecting something, be it coins, cars or CPU’s having the most pristine unblemished example is highly desirable. However, sometimes, the best example is one that isn’t perfect, in coin collecting it may be a rare double struck coin, or some other flaw that actually makes the coin more valuable.
Raspberry Pi 3 Model B+ is now on sale for $35 (the same price as the existing Raspberry Pi 3), featuring a 1.4GHz 64-bit quad-core processor, 3x faster Ethernet, faster wireless LAN, and more.
I recently started FPGA programming and figured it would be fun to use an FPGA to implement the FizzBuzz algorithm. An FPGA ( Field-Progra...
The main feature is fast access to a flat, 24-bit address space. Although there are many ways to retrofit a 'C02 with expanded memory, AFAIK none can touch this implementation for speed. Given any random address in the 16 megabyte space, KK can fetch that byte in 6-8 cyles. It's fast because:
