Ok, I’m going to give BlueSky a proper try. If you’re over there, then ping me on @barsteward.bsky.social If you’re not over there yet, it’d be a good idea to grab an account to secure your username before someone else does (although you can also use your own domain).

@CyberQueenMara 12V 2A wall wort supply that came with my adapter. I've not yet tried switching it to a bench supply to watch the draw.

Is there something special about this old IDE laptop disk from a Gateway 2000 Handbook in the 486 era? My USB/IDE adapter doesn't seem to be able to attach it.

The slides, the (hastily-put-together-really-should-have-been-rewritten-but-working) demo code and the PCB gerbers etc. are all on GitHub here github.com/barsteward-bsi… I will post a link to the video when it eventually gets processed & published on YouTube.

My talk was an intro to fault injection, and went really well - the live demo actually worked! I cited a few notable examples of FI, including @joegrand’s recovery of $2m worth of THETA from a hardware crypto wallet, and the man himself was in the front row.

Had a blast volunteering at @BSidesLondon the volunteers are a fantastic bunch - was great to see both familiar and new faces. Finished with too many cocktails; might need to sleep from now until Christmas to recover though.

When was the last time some weird man followed you from your house to the shops? Today for me.

This is hacking. This is bypassing restrictive locks placed by companies on a product where the feature exists but disabled due to regulatory issues in that country. Nicely done and proper WiFi hacking here (location meddling) wired.com/story/apple-ai…

Just got that call you never want to get. My amazing Dad was just admitted into the hospital in Charlottetown. His doctor is only giving him a couple of days to live, so on our way to #PEI to say goodbye. He has fought AML so hard over these past 6 months after a sudden diagnosis that turned our lives around. He was so healthy, in his 70s and working out daily. We've had many good weeks over these past couple of chemo months that we thought he might have more time, but clearly cancer has other plans 😢.

Went to a bit of a school reunion tonight; saw a bunch of people for the first time in over 30 years! Alcohol was necessarily involved, but was good to catch up! No exes turned up and only a couple of folk who I had zero recollection of so I’m counting that as a win 😬

@TheSimonEvans If you don’t want replies, you can always limit who can reply 😂 I follow you because I’m a fan of standup comedy and I appreciate your dry sense of humour. It’s your prerogative to block if you choose, from my first slightly negative reply in 15 years.

@barsteward I know you’ve had a rough night, but why would you follow someone you think is a muppet then ? To get blocked?
