Into infosec (all of it), amateur radio, microcontrollers and other hardware. If it makes a radio wave it's cool. Aspire to eradicate duhkha.

Really great work! https://t.co/waQx2AV9jR

Your Meshtastic node is transmitting. Who's listening?

My whole argument regarding AI boils down to this:

>>> AI increases output much faster than it increases certainty <<<

Yes, it generates more code, more prototypes, more pull requests and more “solutions”.

But every generated line still needs ownership, review, testing, debugging and long-term maintenance by humans.

And I think the market currently underestimates how expensive that last part really is.

@gojimmypi I’m late, but @MakeAugusta here in AGS could do some for ya.

New blog post on reverse engineering and modifying HDD firmware. In this part I cover obtaining, analyzing, and modifying firmware, using backdoor commands to hot patch code in RAM, and using JTAG to debug a live HDD https://t.co/9vVt26JHxO

Wideband passive receiver for Meshtastic LoRa. One SDR, every preset, channel, and slot in your region decoded in parallel. JSON / ZMQ / MQTT / CoT / pcap out.

Happy hunting. Mileage may vary.

We're looking for a Core Ultra Series 3 laptop (32GB/1TB) for some forensic work, an upcoming video, and another "special" project.

Framework's Laptop 13 Pro was our first choice, but I don't think they're interested in allowing us to have early access. It's been years since we've purchased a PC laptop (we build our own desktops and use Mac laptops).

Recommendations?

[Jeff Murri @InfoSec208]

This would be chip and chip set dependent wouldn’t it?

[Owen Brake @OwenBrakes]

The RF world is insane.

Researchers recovered AES-128 keys from a Bluetooth chip by listening to its own antenna from 10 meters away.

Crypto-engine switching noise couples into the RF chain, rides the 2.4 GHz carrier, and leaks out as radio.

[Florian Roth ⚡️ @cyb3rops]

Okay, wow

Did you know you can now load #GameCube games over your network via #RetroNAS, using a homebrew USB device called #USBDolphin and a USB Ethernet device? Performance will vary, but this is still REALLY cool. Links and more info: https://t.co/TCckKBAJeJ

The @RadionaOrg ULX3S hub site now honors device dark mode! Sunglasses no longer needed 😎

I also added a Tiny Tapeout section, as (pending a few Pull Request merges) @latticesemi #ECP5 FPGA support for testing your ASIC design on the #ULX3S is coming to @tinytapeout

The README for this project is a treat. It walks through each reason why a simple copy of the Dreamcast disc wouldn't work, along with the commented SH4 assembly patch that corrects it.

@d0tslash @eBay The package label looks like it came from AliExpress

[Jeff Murri @InfoSec208]

Highly recommend these.

Good news! The third book of the Architecture of Consoles series is out! 'The Pioneer Race' collects the analyses of the Sega Saturn, PlayStation, Virtual Boy, and Nintendo 64. You can find it here https://t.co/DBWJC7rehB

Took me almost a month, but it’s finally done.

I completely rewrote the first chapter of linux-insides about the Linux kernel initialization process. Now it should be aligned with modern kernels (up to master).
