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:
A collaboration with Jared . Before any build log, here's a video: That was a Rubik's cube being solved in 0.38 seconds. The t...
The above shows my home-built digital clock. It uses Nixie-tubes for readout. In contrast to most other nixie-clocks being built these days, my clock does not use any transistor or IC for driving the tubes. Instead, the driving logic is built from neon lamps , together with resistors, capacitors and silicon diodes.

This content was originally meant to be presented as part of my workshop on Rust and microcontrollers at the NITC FOSSMeet 2018 . As I was not able to cover it satisfactorily during the workshop, I thought of writing it down!
A portfolio of HPC tools help data scientists, researchers, and developers efficiently build cross-architecture applications.
Hardware Bugs can be frustrating, as they are likely the last place you would expect a bug. Unfortunately, they can and do happen. Most likely every CPU has a list of erratas. This post outlines th…
MIT and Harvard physicists have created a new form of light that could enable quantum computing with photons.
At Recode’s Code Media conference on Feb. 13, 2018 (a few hours ago as I write this), they live streamed an interview with Ronny Abovitz, CEO of Magic Leap and NBA commissioner Adam Silver. The int…
