Reminder: I offer free mentoring and mock interviews. Embed sys, C++, perf analysis, at-scale monitoring, and more. Grab a spot on my calendar at calendly.com/kc8apf.

Really need to figure out a better chute for Big Chippin'. Filled the truck bed but dumped 6" of chips on the ground, roof, hood, ...

Checked alignment on microscope today. It's so far off that the normal adjustments can't compensate. Guess it's as good a time as any to open it up and do a thorough cleaning.

How to assess a secure MCU:
1. Beg for a datasheet
2. Sign NDA
3. Buy an eval board
4. Load program to dump ROM
5. RE ROM
6. Find undocumented registers and devices
7. Disbelief
8. Pick another device, repeat

Security through hiding rows in Excel 😬

Bought a preheater. Reworking TQFP-100 with an exposed pad is a breeze now.

Today's trebuchet progress: frame mostly built. Need to work out pouch design and quick release.

Planning a trebuchet build with my kids. Started with some drawings and calculations.

"hidden coprocessor" is exactly what I want in a security-focused microcontroller: nxp.com/docs/en/application-no

Hewlett Packard Enterprise #HPE is now working on open source #firmware, thanks to Jean-Marie Verdun having joined them.

See osfci.tech for a cool demo.

This post below is in #French.

Hot take: FPGAs are just very, very long instruction word (VVLIW?) processors

Guess I'm going to be the one to write an IPMI performance benchmark.

TFW you recognize throughput is varying with latency because every IPMI implementation sends requests sequentially instead of pipelining.

A #mastodon exclusive! You are invited to play on a *REAL* PDP-8/e running the TSS/8 monitor (TimeSharing System 8) pictured here. There is a user contributed tutorial here:

wiki.livingcomputers.org/doku.

To connect, ssh tss8@tty.livingcomputers.org

If you are unable to connect that means all 6 (yes, just 6) lines are in use. Remember, this is real hardware and there is NO EMULATION happening. It is the real deal! Enjoy!
