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 http://calendly.com/kc8apf.
A few months ago, chandelier over our dining room table fell off. It has been improperly installed and the electrical box was ruined. After many weekends of repairs, new lights are installed. Decor by @jaycarmona@twitter.com.
In the spirit of NFTs, I propose UnsafeCoin. Mining is a side effect of compiling Rust code. Coins may be used to buy indulgences that allow you to use the unsafe keyword. Each indulgence generates an NFT to commemorate the event. I will not be taking questions at this time.
Line trimmer has a compatible, but not OEM, carburetor. Worked on it for an hour before realizing high and low speed adjust are reversed from OEM. 🤦
Preparing for winter with a new wood rack built from scraps. Trips to the wood shed should be much less frequent.
Found a really good deal on Akro-Mils bins on Craigslist. Finally sorted my common cables.
NXP has updated a few LPC55S69 documents since our DEFCON talk. Spreadsheet attachment removed from UM11126. AN12868 changed "hidden coprocessor" to "dedicated processor." Still no public notification of CVE-2021-31531. Feels more like a coverup than an disclosure.

"Fault injection attacks against AMD's Secure Encrypted Virtualization" is this morning's highly recommended breakfast reading https://arxiv.org/pdf/2108.04575.pdf

@kc8apf and Laura Abbott's talk at DEFCON29 on finding TrustZone-M exploits through reverse engineering boot code, application notes and Excel spreadsheets to find an undocumented ROM patcher: https://www.youtube.com/watch?v=eKKgaGbcq4o
Had an opportunity to practice lock picking under pressure today. Got my partner's office door open before their next meeting.
Once again reminded that Network Solutions has no obvious way to enable DNSSEC for a domain and that domains with expirations >10 years in the future can't be transferred. Only 1 more year before I can change registrars.
Feeling more engineering manager than SWE lately. Not necessarily a bad thing.
With Jay's help, tilted back Big Chippin's chute to get access to the cutter head and chip breaker. Pretty sure that chute is made out of 1/8" steel and weighs 300+lbs. It was a struggle.

are you a lead/maintainer on a pretty popular open source project? I'm looking to talk to a couple of people to find out more about how other OSS projects work! Hopefully that'll help us improve how we handle community/contribution stuff for NuGet itself! Reply or DM :)
Something has gone awry with this 1/4" mandrel. That it occurred with a hand drill tells you how my wrist feels right now.
Kids helped frame out the gables today. Only required one trip to town for lumber, screws, and root beer floats.
