I thought the @districtcon.bsky.social year 0 badge was one of the most beautiful pieces of PCB art I’d ever seen w the cherry blossoms and the backlit LED, so I finally got around to making it into a little night light for my office.

Made it home for some snow cream today 😋

My buddy @travisgoodspeed talking @districtcon about dumping the ROM in Chinese clone STM32s we found in embedded RE class 😁

It is the tradition of my people that upon returning from a journey I must present tribute, and if the tribute is deemed acceptable, I will be welcomed back into the tribe.

We're really excited to present our Sponsors Job Board! If you are in the market for a new role, check out the listings on our page. These roles are curated by our sponsors and they'll be at DistrictCon Year 1 ready to chat about the roles! T-3 days! 😎 www.districtcon.org/job-board

The arithmetic/logic unit (ALU) in the Intel 8086 processor (1978) is more complicated than you might expect, performing 28 different operations from addition and logical AND to shifts and BCD adjustment. A special control circuit reconfigures the ALU for each operation. Let's look closer...

DISTRICTCON IS STILL A GO! We are excited to see you all on Saturday, January 24 as we are still going through our normal programming! While we are unable to process refunds, we are adding virtual components to Saturday AND Sunday including a livestream for public sessions for ticket holders.

All packed for @districtcon.bsky.social ! Planning to Metro in and leave Sat night, but I’m prepped for anything…like, y’know a power outage?

We still have seats open for @blackhoodie.bsky.social at @districtcon.bsky.social on January 23rd in Washington DC! The class will be reverse engineering their way through an integer overflow bug in libpng 🤓 blackhoodie.re/DistrictCon2...

HAPPY FRIDAY!!! Our Agenda is now live! Check it out! Check it out: www.districtcon.org/speakers

Made a new dev kit with 2 N-type inputs.

Anybody going to @districtcon.bsky.social ?

I made cigar box dev kits for my friends (maybe the best embedded hackers in the world) for Christmas this year. We use them at work for portable embedded RE/dev. Used two Arturo Fuente boxes.

All I want for Christmas is to not have to participate in anxiety Christmas ever again.

‘‘Twas the night before Christmas…

Take a shot every time you hear “never seen before” 🥃🇺🇸

Welp…guess we’re not decorating the tree this year 😆

Tempted to do some clandestine RE at my boys’ tournament 😆

When you read a tech CEO talking about "teaching machines to be human" and it's like "bro, have you even taught another human how to be a human" ??

Looking for recs for burning PCBs as an art project - I used a butane torch but it’s a little uncontrollable what burns and sometimes it delams…I can use a soldering iron but it takes a long time…

I would laugh if this wasn't so true 😭

My spoooky story of the week: learned about quiet NaNs” in IEEE754 (which is spooky enough!). They are the ghosts of floating point…even if you have all FP exceptions enabled, if a std lib function or an instr generates one they propagate through subseq instructions. Eerie!👻#

My lesson for today was quiet NaNs and signaling NaNs…look it up…it *is* spooky season after all…🎃

@wbm312.bsky.social gave me this payphone pin @shmoocon.bsky.social one time and it’s the coolest pin I’ve ever seen, and I kept thinking I needed to save it for special occasions but it’s too cool not to display, so it’s on the bag now next to the pirate jelly (that I made).

Love the smell fresh ROMs in the morning…smells like victory.

TRON is *the* best hacker movie, don’t @ me

Can we please have a Cybersecurity Unawareness month?

Proud to have served my country for 20 years @jhuapl.bsky.social

There is some kind of anti-AI smash-the-machines society I can join, right?

Thanks for the hookup my friend 🙏🫵

With Tom Lehrer's passing, I suppose this is a moment to share the story of the prank he played on the National Security Agency, and how it went undiscovered for nearly 60 years.

Did anything happen @defcon.bsky.social today?

Got this too late for @districtcon.bsky.social 0…but maybe I’ll get to wear it to DC 1!

RE something something… hack hack hack 🏴‍☠️🏴‍☠️🏴‍☠️

Memories from DistrictCon 0 (lots of fun and great talks yesterday due to the persistence of the volunteers) - view from the hotel they sent refugees to…this morning you can see a pile of old cable bits in a dump truck and several spool trucks ready to run new lines.

I have these @districtcon.bsky.social for the hacker parents and kids!

Lightning submissions are open! If you're coming to RE//verse and have an interesting topic that isn't ready for a full talk, email [email protected] with a description for a 5-10m lightning slot. The process is informal and open to all attendees. Sign-ups available throughout the event as well.

So this US / Canada hockey thing - anybody have a sense for how bad this is for foreign relations or is the fighting all just part of the fun of it (it is hockey after all)?

Anybody out there have a good connection on a college baseball team staff?

Got my @districtcon.bsky.social ticket today! Hoping to meet @halvarflake.bsky.social for the first time.

This Justin: Canadian PM resigns. Not sure if Trudeau

Oh man DeNiro something 0-day cyber something

Submit those training requests at work! @natashenka.bsky.social not only has an inspiring hobbyist-to-pro story, but she is quite good at making a super technical RE story fun and engaging.

So I'm at elem school basketball practice on Thurs (I'm an asst coach) and mid-practice a kid starts asking me about hacking his wifi router - and so between drills we talk about through-hole vs. pads, UARTs, where to buy an FTDI UART cable... 🤯
