The decryption function If you are just joining this story you may want to start at part 1. In part 2, we discovered that a embedded controller update is performed by uploading a small 'flasher' program to the EC. This flasher program is then responsible for programming a new firmware image t
For some time now, I've been reverse engineering the firmware of the Broadcom BCM5719 Ethernet NIC chip, so that open source firmware can be produced for it. The BCM5719 is a PCIe chip which provides up to four Gigabit Ethernet ports, and is mainly intended for use in server applications. It can be used with the Linux…
Putting iroh on a bare ESP32 to build a temperature-driven smart fan you can check on from anywhere.
Millions of U.S. government employees and contractors have been issued a secure smart ID card that enables physical access to buildings and controlled spaces, and provides access to government computer networks and systems at the cardholder’s appropriate security level. But many government employees aren’t issued an…

Translations: This article was translated to Simplified Chinese by Xiong Duo and to Korean by Matt Lee (이 성욱). Introduction I want to make solid-state drives (SSDs) the optimal storage solution for my key-value store project. For that reason, I had to make sure I fully understood how SSDs work, so that I can optimize
The previous post described [motherboards and the memory map] memory-map in Intel computers to set the scene for the initial phases of boot. Booting is an involved, hacky, multi-stage affair - fun st
Last time I wrote about profiling in Zig on Apple Silicon, I touched on PMU counter profiling. This time I decided to go further and create my own tool to fetch all available counters for Apple Silicon processors (M1, M2, and later). Brief explanation of PMU counters PMU (Performance Monitoring Unit) counters are…
SparkFun is forced to incinerate 2,000 multimeters because they are yellow.
We took the Duo all the way down to the gears, followed glowing dust into its hinge, and put its crease-hiding nano-texture under the microscope.
Chips are the clearest example that economic efficiencies will not be the ultimate decider of technology’s end state: politics will play an important role.
If hyperscalers and chip companies don’t build up a TSMC competitor they are set to forego billions of dollars in revenue and stunt the AI revolution.
Testing the new iPhone 12 Pro in (and over) Glacier National Park.
In-memory workloads continue to be the backbone of innovative data management use cases, but as demand increases, so does the need for even larger memory capacity. In July, we announced a partnership with Intel and SAP to offer GCP virtual machines supporting Intel® Optane DC™ persistent memory for SAP workloads. This…
As you may remember, or completely not know, I have a bit of a fascination with old rotary phones . Occasionally, when people learn about this fascination, they donate their old rotary phones to me, so I have ended up with a small collection.
