Complex software is, to put it mildly, hard to get right (for details, see almost any other posting on this or any other security blog). Especially for gadgets that are rich with microphones, cameras, location and environmental sensors, and communication links (such as, you know, smartphones), errors and security…
Listen to WWV announcement recorded 0008UTC 11/4/2021 from WWV 10MHz broadcast, receiver IC-7300 13.7km from the station.
Last year I spent a bit of time building a Kubernetes cluster with the original Turing Pi. It was fun, and interesting, but ultimately the performance of the Compute Module 3+ it was designed around led me to running my homelab off some newer Pi 4 model B computers, which are at least twice as fast for almost…
Researchers at Princeton University and the University of Washington have developed an ultracompact camera the size of a coarse grain of salt. The new system can produce crisp, full-color images on par with a conventional compound camera lens 500,000 times larger in volume.
We announced the first generation AWS-designed Graviton processor in late 2018, and followed it up with the second generation Graviton2 a year later. Today, AWS customers make use of twelve different Graviton2-powered instances including the new X2gd instances that are designed for memory-intensive workloads. All…
Engineering physics PhD student Khadijeh Miarabbas Kiani has fabricated a laser on silicon using a simple, cost-effective method - something that has been a longstanding challenge in the field of silicon photonics. [...]Read More...
The Yamaha DX7 digital synthesizer was released in 1983 and became extremely popular, defining the sound of 1980s pop music. Because micro...
Highlights Check Point Research discovered vulnerabilities in MediaTek’s chips, embedded in 37% of all smartphones globally CPR discovered several %
The other day I asked myself a seemingly trivial question: What was the first ATAPI CD-ROM drive and when was it available? Given that ATAPI was a major technology which instantly obsoleted all proprietary CD-ROM interfaces and made SCSI much less desirable, one might expect that there would have been some press…
Since the Compute Module 4 came along last year, there have been a few projects that use it that make me do a double-take: They did what with a Pi? Alftel's Seaberry is a carrier board for the CM4 in the Mini ITX form factor that adds on eleven PCI Express slots: 1 x16 slot (with x1 lane) in the standard ITX location…
As we head into another gifting season and more and more connected devices make their way onto gift guides, I want to offer a cautionary note. The smart home is like a cat — mostly self-sufficient and nice to have, but also possessing a mind of its own that can lead to frustration and confusion […]
Introduction It was nice to get out and actually look through AR and VR displays at AWE 2021. I started to write about everything I saw at AWE, but to me Tilt-5 was such a standout that I decided t…

Yeah, so about that OpenPOWER Minimum Viable Product JavaScript JIT for Firefox. This happened (all timings from an unoptimized debug build ...
I’d recently bought a new XPS13 7390 (non 2-in-1) laptop. I had bought the 8GB variant, how hard could it be to upgrade?
TOKYO, Japan ― Renesas Electronics Corporation (TSE:6723), a premier supplier of advanced semiconductor solutions, today announced that it is entering the Field-Programmable Gate Array (FPGA) market with a new line of very low-cost, very low-power devices. The ForgeFPGA™ Family will address the underserved market need…
TL;DR : we reproduced Denis Andzakovic’s proof-of-concept showing that it is possible to read and write data from a BitLocker-protected device (for instance, a stolen laptop) by sniffing the TPM key from the LCP bus.
When I heard about Radxa's Taco—a Raspberry Pi Compute Module 4-powered NAS/router-in-a-box—I knew what must be done. Load it up with as much SSD storage as I can afford, and see what it can do. And after installing five Samsung 870 QVO 8TB SSDs and one Sabrent Rocket Q NVMe SSD—loading up every drive slot on the Taco…
Every day I make a cup of coffee, organize a list of the things I want to do that day, and try to work through it. Every time I finish one of the tasks, I mark it as complete. By the end of the day, ideally there are no things left on the list, but if there are, I’ll move them into a backlog and start fresh the next…
Purdue University is a world-renowned, public research university that advances discoveries in science, technology, engineering and math.
AMD has been working with Blender to improve support for GPU rendering in Cycles using the open source HIP API.
We demonstrate that it is possible to trigger Rowhammer bit flips on all DRAM devices today despite deployed mitigations on commodity off-the-shelf systems with little effort. This result has a significant impact on the system’s security as DRAM devices in the wild cannot easily be fixed, and previous work showed…
The Yamaha DX7 digital synthesizer was released in 1983 and became "one of the most important advances in the history of modern popular mu...
Electric cars are fantastic compared to ICE vehicles, but E-Bikes are even better. Much lower environmental impact and far more suited to medium range travel such as commuting. Here in NL they sell in huge numbers, far faster than electric cars. But they also have their limitations: a regular e-bike tops out at 25…
The purpose of this article is to explain how to make a CPU out of rocks and sand as fast as possible without using too many words. As the world of proprietary hardware and software crushes in around us, we risk losing the ability to make things for ourselves as individuals. It is for this reason that I felt compelled…
There are longer tutorials on how to connect a USB printer to a Raspberry Pi and make it accessible via AirPrint but here's the minimal one ...
