On a related note: "thinking the unthinkable" when faced with a design is what I do best and enjoy most. Then things happen ¯\_(ツ)_/¯

So, why do I care about firmware/hardware/ucode hacks? > (threadp) t > Well, for the best part of 30yrs I was always curious about building "the ultimate virus" combining techniques from pretty much everywhere. This, inevitably, leads you to interesting avenues, the vast…

The new nuclear "Basic Principles" just dropped (h/t @KomissarWhipla). The key change is that it's the aggression that "poses critical threat to the sovereignty and/or territorial integrity" instead of "puts the very existence of the state in jeopardy" publication.pravo.gov.ru/document/00012…

I tried to build a $599 PC to match the performance of the $599 Mac mini—size and efficiency be damned. I could not do it. You cannot build a better PC at $600 using new parts. Period. But the Mac mini is only a good deal if you leave it as is; upgrading makes it a bad deal.

<sigh> Here we go again. How many times do we have to say providing big tech companies with more sensitive personal data is not the answer to online safety issues? Do we really want social media companies to store our children's biometric and identity data?

We really do stand on the shoulders of giants. The hobbyist computer bulletin board system (CBBS) was introduced in 1978 by Ward Christensen. It was the first BBS bought online and allowed people to message each other. vintagecomputer.net/cisc367/byte%2…

Ward was a phenomenal inventor, and subsequently created XMODEM. Sadly Ward passed away yesterday at the age of 78. Fitting number given his contributions to the Internet and all that we use today. Thanks Ward and RIP

Just for once I would love to see a popular paper that asks "…how much of what we esteem as 'reasoning' is actually just 'pattern matching?'"

1/ Can Large Language Models (LLMs) truly reason? Or are they just sophisticated pattern matchers? In our latest preprint, we explore this key question through a large-scale study of both open-source like Llama, Phi, Gemma, and Mistral and leading closed models, including the…
