This is not related to null bytes contained within Channel File 291 or any other Channel File.

That to me implied that the channel file wasn’t actually necessarily corrupt (or as corrupt as people thought), but that it triggered a logic error. In particular this point implies that it wasn’t from garbage zero bytes in the file.

(That said I could have worded this better, in my defense I’m sick in bed and only half thinking straight)

I don’t want to hear that I’m irrational from Roko of all people haha.

Dude sure spends a lot of energy on trans people and immigrants and wokeness for someone who thinks that climate change doesn’t matter because “by 2100 we will probably have disassembled Earth long with the rest of the solar system, and climate change will seem very quaint.”

Also is his flirting with white supremacy new, or has he always been that fascist of a weirdo?

Fair warning that I’ll be ranty because I hate losers talking about DEI hires.

So why is memory address 0x9c trying to be read from? Well because… programmer error.

So what happened is that the programmer forgot to check that the object it’s working with isn’t valid, it tried to access one of the objects member variables…

This is a huge assumption. The last rumor I’ve read from actual cybersecurity people is that Crowdstrike’s update files were corrupt (update: disproven by Crowdstrike’s blog post). If this is true it’s likely still from programmer error at some level, but maybe not as simple as “whoopsie I forgot an if (data == nullptr) teehee”.

He, like the rest of us that don’t work at Crowdstrike, has no idea what happened. I have seen computers do the weirdest gosh darn things. I know better than to assume anything at this point. I wouldn’t even rule out weird stuff like the data getting corrupted between release qualification and release yet.

It turns out that C++, the language crowdstrike is using, likes to use address 0x0 as a special value to mean “there’s nothing here”, don’t try to access it or you’ll die.

This thread is full of these sorts of small technical inaccuracies and oversimplifications so I won’t point out all of them, but nothing in the C++ standard requires null pointers to refer to memory address 0x0. Nor does it require that dereferencing a null pointer terminates the program.

Windows died not because C++ asked it nicely to, but because a driver tried to access an address which wasn’t paged in.

Crowdstrike should have set up automated testing using address sanitizer and thread sanitizer that runs on every code update.

The funny thing about accessing into non-paged memory in kernel space:

1. It will crash regardless of if it’s running under Asan or not, sanitizers are literally irrelevant based on what we know so far
2. The Asan version he linked to is for user-space. In the windows kernel you’d need KASAN instead.

(If this was a simple nullptr dereference on bad input data then perhaps a fuzzer would have helped. Fuzzers are great though I have no idea how hard they are to use with kernel drivers)

C++ is hard. Maybe they have a DEI engineer that did this

Dude would probably call me a “DEI hire”; but I bet I could beat him in a C++ deathmatch so neener neener.

Zach Vorhies (who made leaking Google stuff to Project Veritas his entire identity) has the worst possible take: https://twitter.com/Perpetualmaniac/status/1814405221738786984 (lemme gather my thoughts and explain why in the next comment)

The one catch is that because responses from the blockchain can take variable amounts of time, it’s best to request and receive from blockchains using asynchronous methods.

“You may be used to writing websites that actually load in fractions of a second, and so rely on obsolete web2 technologies like synchronous fetches. But don’t worry! With modern techniques like async / await your loading spinner will animate flawlessly while the blockchain spends 20 minutes burning down a forest in the background.”

Unfortunately we’re unable to share details about the training and the datasets (extracted from the open Web) due to the highly competitive nature of the field.

The “open web” is full of copyrighted material.

HN: I am starting an AI+Education company called Eureka Labs.

Their goal: robo-feynman:

For example, in the case of physics one could imagine working through very high quality course materials together with Feynman, who is there to guide you every step of the way. Unfortunately, subject matter experts who are deeply passionate, great at teaching, infinitely patient and fluent in all of the world’s languages are also very scarce and cannot personally tutor all 8 billion of us on demand. However, with recent progress in generative AI, this learning experience feels tractable.

NGL though mostly just sharing this link for the concept art concept fart which features a three-armed many fingered woman smiling at an invisible camera.

AI Maxers Thrilled with Trump’s Vice President Pick JD Vance

This isn’t really too interesting yet; but something to keep an eye on. As things like blockchain and AI alignment becomes weirdly political it’s likely that sneering will get unpleasantly close to politics at times. And yet sneer we must.

Other self-titled techno-optimists highlighted Vance’s ties to venture capital, Thiel, and Andreessen, saying the “Gray Tribe [is] in control.” Gray Tribe is a reference to a term originating from Scott Alexander’s Slate Star Codex blog, which points to a group that is neither red (Republican) or Blue (Democrat), but a libertarian, tech savvy alternative.
