Dennis Ritchie, the man who invented C, co-created Unix, and is largely regarded as effectively influencing every software system we use on a daily basis. His death was largely ignored, overshadowed by Steve Jobs' death, one week before.

No surprises here, but @CrowdStrike confirms @taviso's analysis, that the bug was indeed not due to a NULL-pointer deference 🧠 ...but rather "an out-of-bounds memory read"

Regardless of race, language or religion…In Singapore we embrace diverse cultures and traditions, integral to our shared identity & bonds. Wonderful to see kids celebrating this diversity; instilling these values young moves us toward one united people. Happy Racial Harmony Day!

Apollo 11, Daily News, July 21, 1969. ✍️

July 20th, 1969 is a date that stands high in my life – it was the day that we, together as one people, achieved the greatest scientific and technological feat in human history. The specific role that Neil, Mike and I performed in the event was but one part of an immeasurably larger effort – not just for our nation, but for all mankind. As I look back on what we accomplished 55 years ago, I am still inspired by what we all saw and did – the best of America and the best of humanity. Thank you for the privilege and the honor of serving you, and for being part of this exciting and wonderous journey with me. #Apollo11

"The Eagle has landed." On July 20, 1969 — 55 years ago today — #Apollo11 touched down on the Moon.

How we did this in the old days: When I was on Windows, this was the type of thing that greeted you every morning. Every. Single. Morning. You see, we all had a secondary "debug" PC, and each night we'd run NTStress on all of them, and all the lab machines. NTStress would run a gauntlet of harsh tests on the latest daily Windows build. If a component crashed overnight, you'd get an email with a link to a text debugger (really more of a fancy monitor) and a call stack. It was then your job to either diagnose it from the call stack or connect to the debugger and figure out what crashed and why, then open a bug (or fix it). Or if you were lame or unlucky, you could say "bad symbols, can't debug, reboot". I hated that. For those new to it, a dump like this can be a bit opaque. But what you're looking at is a piece of code in csagen1 that has tried to de-reference through a null pointer (or more accurately, a non-zero BS address of x9C). And so it crashed, and given how deep the call stack is into csagen, at that point you'd call the developer responsible for csagen and give them the remote so they could look at it. The problem in this case is that csagen isn't a Windows component at all, it's the Crowdstrike driver. My current understanding is that the driver itself passed WHQL and is signed, but that it can download p-code and execute THAT, and that the p-code isn't signed (by Microsoft, at least). Not to belabor the point, but Windows is no different than Linux or Mac in this regard - if you install a third party driver into Ring0 of your system and it access violates, the only difference is the color of your screen when the system goes down (it's Pink on my Mac).

I thought we all learned from that data guy that we shouldn't retweet people who draw random red lines over assembly? 😆
