You're probably reading this page because you've attempted to access some part of my blog (Wandering Thoughts) or CSpace , the wiki thing it's part of. Unfortunately you're using a browser version that my anti-crawler precautions consider suspicious, most often because it's too old (most often this applies to versions…
We have been very public about how reliable Samsung SSDs have been in the past, so we wanted to explain why we are now moving part of our line to Sabrent.
[Note to the impatient: to try out my beamforming simulation, which produced the above image, visit my beamlab test page - ideally in a brow...
Thanks to a discovery in a Dal lab, manufacturers of laptops and other tech devices now have an explanation for why the batteries that power their gadgets tend to lose some of their charge over time and a path forward to fixing the problem..
...that was the question I asked my Dad, a radio engineer for many decades, who worked at the biggest AM station in St. Louis, KMOX. The station is approaching its centennial in 2025, as are—some YouTube commenters argue—its primary audience! I recorded that video during my convalescence at my parents' house (I am…
I am writing this memo to explain what happened to the case our NeXTCube Computer, Serial Number AA001032.
A few days ago, on a certain orange website, I came across an article about an improvised parallel printer capture device . This contains the line:
It's time to add another family of emulated older technology to the Internet Archive.The vast majority of platforms within what we call The Emularity happens because of the work of MAME Team, which has spent over 25 years adding support for tens of thousands of machines, platforms, and tools to their breathtaking…

The ThinkPad as a server is back, this time with a couple of adjustments.
I always wanted to understand how a CPU works, how it transitions from one instruction to the next and makes a computer work. So I thought: let's implement one and run a C program on it.
First, what is an ASIC? An ASIC is an Application Specific Integrated Circuit which basically means that it is an Integrated Circuit on a single piece of silicon and its use is limited to a particu…
Reverse engineering the kernel-mode authenticity check, and how Microsoft knows about your hacked/custom hard-drive.
This is the Compute Blade, and I'm test driving it in a four-node cluster: I'm testing the Dev version, and @Merocle from Uptime Lab sent four Blades, a 3D-printed 4-bay case (a metal 1U rackmount enclosure is in the works), and two fan modules. He's been testing 40 of these in a rack at Jetbrains for months, and…
When you buy a USB charger, how do you know if you're getting a safe, high-quality charger for your money? You can't tell from the outside...
Intel introduced the 8086 microprocessor in 1978 and it had a huge influence on computing. I'm reverse-engineering the 8086 by examining t...
It turns out that the first “all Google” phone includes a non-Google bug. Learn about the details of CVE-2022-38181, a vulnerability in the Arm Mali GPU. Join me on my journey through reporting the vulnerability to the Android security team, and the exploit that used this vulnerability to gain arbitrary kernel code…
I am now a staunch advocate for ECC RAM, after the events of last week. You see, over the last several weeks my main desktop workstation has been misbehaving, with occasional freezing and crashing. After some diagnostics I began to suspect a faulty RAM module, and sure enough, upon performing a quick run of memtest86…
A community and blog for embedded software makers
Here, I provide an in-depth analysis of GPUs for deep learning/machine learning and explain what is the best GPU for your use-case and budget.
IBM kicked off the IBM Quantum Summit 2022, announcing new breakthrough advancements in quantum hardware and software and outlining its pioneering vision for quantum-centric supercomputing.
Standard-class Gen5 navigation
Back in the summer I was lucky enough to finagle my boss into letting me take Dmitry Nedospasov ( @nedos )’s hardware hacking training . In it I cut my teeth on using an FPGA to interface with target hardware. After implementing a UART we implemented a module that could parse part of Apple’s OneWire, used to negotiate…
Apple today announced the new 14- and 16-inch MacBook Pro featuring M2 Pro and M2 Max, Apple’s next-generation pro silicon.
An introduction to my MCU based fully featured analog telephone exchange, how I mounted it in my home lab powered with batteries for months of use
How many transistors are in Intel's 8086 processor? This seems like a straightforward question, but it doesn't have a straightforward answ...
This is a write-up of the wInd3x bootrom exploit affecting iPod Nanos from 3rd gen to 5th gen. A ready-made tool to use this exploit is available at github.com/freemyipod/wInd3x .
I made a custom split mechanical keyboard! Because it's me, this involved things like contributing to a PCB design tool and discovering a ridiculously optimized way to read a keyboard matrix.
