A working recipe for getting a jfirmware PIC update installed on a Juniper SRX320 running 64-bit JunOS 24.4+ when the only available jfirmware package is from an older 32-bit release (24.2).

By default, FreeBSD jails can’t see /dev/dri/* — the kernel hides it via devfsrules_jail.

There is no ROCm/HIP on FreeBSD.

Build a “golden” FreeBSD jail with Claude Code pre-installed, snapshot it on ZFS, and zfs clone that snapshot to spin up working sandboxes in seconds.

Claude Code ships as a Linux ELF binary (bun-based, statically linked against glibc).

Design to reality I recently ordered my tenth batch of PCBs from PCBWay.

So you went on eBay and purchased some used SAS disks that were previously in an EMC device (or some other scenario where you ended up with disks that have non-standard block sizes) and when you use them on your system, you see something similar to the fo…

I’m currently working on a large logging project that was initially implemented using AWS Elasticsearch.

Things I love: Electronics, Nuclear stuff Things I hate: Kids shitting up the WiFi I was nearly complete with a completely different badge for Telephreak this year, but then an idea popped into my head while watching the excellent Chernobyl miniseries.

Years ago, I was working with Poudriere to set up an ARM build system on FreeBSD on x86-64.

Our parts have arrived and our boards are ready; let’s build some electronics!

After assembling over 200 Telephreak badges by hand for DEFCON 26 (and taking *way* longer to accomplish it than I estimated) I figured I should document some of the lessons that I learned along the way – from initial design to finished product.

I discovered some unexpected behavior with AWS Lambda that I thought was worth pointing out.

Hey everybody, just wanted to give a quick status update on the Telephreak badges.

Welcome to the Telephreak 11 badge!

Fortunately, thanks to the work of radiomanV, it’s very easy to get your XGecu TL866II working under Linux with Wine.

Thanks to my good friend Marc Uchniat for helping develop this idea As networks grow larger and faster, monitoring technologies have a difficult time scaling.

After several unsuccessful attempts to figure out how the password for the PKCS12 archives is generated, I decided to build a jig to interface with the diagnostic port on the front to see if I could find a JTAG interface.

After the previous post, the first order of business was to get the capacitors and battery replaced.

Wrapping your head around the use of bitwise operators can be daunting in the beginning.
