Setting up Starlink
In March, I got an email from SpaceX saying Starlink was available at my address, and I could pre-order. I paid $500 for the equipment, plus $25 for a Volcano Roof Mount, and $99 for the first month of service, and a few weeks later, I got the kit you see in the image above. I was a little too excited about getting…

Zen 2 Missives – AMD now delivering efficiencies that are double that of Intel
After languishing through the CPU dark-ages (read: Intel trying real hard to keep people on 4 cores so they could charge an arm and a leg for more), the last two years has seen a vertible tsunami of advances in CPU technologies. AMD's introduction of an 8-core CPU (the 1700X) began the rat-race and with both AMD and…

Apple M1 foreshadows Rise of RISC-V
The M1 is the beginning of a paradigm shift, which will benefit RISC-V microprocessors, but not the way you think.

Raspberry Pi 4 not working with some chargers
The new pi has been released and it has a USB Type-C connector for power however people are finding some chargers are not working with it (notably macbook chargers). Some have speculated that this is due to a manufacturer limitation on the power supplies however it is actually due to the incorrect detection circuitry…

The new MacBook Pro is kind of great for hackers
A million hot takes have been posted about how the late-2016 MacBook Pro with USB-C is the undeniable proof that Apple doesn’t care about…

Using eSIMs with devices that only have a physical SIM slot via a 9eSIM SIM car
Do you have a phone, tablet, or laptop (or, well, any device…) which will only take a physical SIM, but with which you’d like to use eSIMs?

On Hacking MicroSD Cards
Today at the Chaos Computer Congress ( 30C3 ), xobs and I disclosed a finding that some SD cards contain vulnerabilities that allow arbitrary code execution — on the memory card itself. On the dark side, code execution on the memory card enables a class of MITM (man-in-the-middle) attacks, where the card seems to be…

It's hard to justify buying a Framework 12
My nephew just graduated high school, and wants a laptop. When he decides what computer to buy, price (or more precisely, value) is the most important attribute. Apple's MacBook Neo upended the 'value laptop' equation—Apple's not supposed to be both the cheapest option and the best value... but it seems like that's…

Don't use Linksys routers
Back in 2012 I gave a talk at a conference titled Blended Threats and JavaScript . I demonstrated how anybody could design an internet worm that targeted common network devices like routers and turn them into a powerful botnet that is able to monitor traffic across all types of networks. For the pr

Cheap HDMI capture for Linux
Lately I have had the need to do real time video capture from HDMI devices as of late for a project, and while looking around the internet found that all of the capture cards that are aimed at gamers (windows / OSX support only) or full blown production capture (Very expensive, more inputs than I need). The other…

How big a solar battery do I need to store all my home's electricity?
I have a modest set of solar panels on an entirely ordinary house in suburban London. On average they generate about 3,800kWh per year. We also use about 3,800kWh of electricity each year. Obviously, we can't use all the power produced over summer and we need to buy power in winter. So here's my question: How big a…

Matter – Protocol to connect compatible devices and systems with one another
The Connectivity Standards Alliance has certified and released the first version of the Matter smart home interoperability protocol Tuesday and I couldn’t be happier. This means that member companies can now put their devices through the certification protocol and get a badge showing that their products are Matter…

Finding a 27-year-old easter egg in the Power Mac G3 ROM
I was recently poking around inside the original Power Macintosh G3’s ROM and accidentally discovered an easter egg that nobody has documented until now.

Tracker Beeper (2022)
A week ago, I finally got round to implementing an idea I’d been toying with for years: what if your computer made a little bit of noise every time it sent data to Google? From studying logs, I’d long known just how many sites send all your visits and clicks to (at least) Google, but a log that you have to manually…

Apple Vision
Apple Vision is incredibly compelling, first as a product, and second as far as potential use cases. What it says about society, though, is a bit more pessimistic.

Privacy friendly ESP32 smart doorbell with Home Assistant local integration
Privacy focused “smart” doorbells seem to be few and far between so I decided to build one that integrates with Home Assistant via ESPHome and is easy to build.

The best laptop ever made
Apple has made many great laptops, but the 15-inch Retina MacBook Pro (2012–2015) is the epitome of usefulness, elegance, practicality, and power for an overall package that still hasn’t been (and may never be) surpassed.

Intel will add deep-learning instructions to its processors
Some of the latest Intel processors support the AVX-512 family of vector instructions. These instructions operate on blocks of 512 bits (or 64 bytes). The benefit of such wide instructions is that even without increasing the processor clock speed, systems can still process a lot more data. Most code today operators…
