Going faster than memcpy

Going faster than memcpy While profiling Shadesmar a couple of weeks ago, I noticed that for large binary unserialized messages (>512kB) most of the execution time is spent doing copying the message (using memcpy ) between process memory to shared memory and back.

A Kentucky Town Experimented With AI. The Results Were Stunning

gizmodo.com Ece Yildirim 2025-12-03 12:34:47

A county in Kentucky conducted a month-long “town hall” with nearly 8,000 residents in attendance earlier this year, thanks to artificial intelligence technology. Bowling Green, Kentucky’s third largest city and a part of Warren County, is facing a huge population spike by 2050. To scale the city in preparation for this, county officials wanted to incorporate the community’s input. Community outreach is tough business: town halls, while employed widely, don’t tend to gather a huge crowd, and w

The Real Reason You Haven’t Been Replaced by AI Yet

gizmodo.com Luc Olinga 2025-12-03 12:44:46

It’s the ticking time bomb in the global economy, and every CEO knows it: AI is already powerful enough to replace millions of jobs. So why haven’t the mass layoffs begun? The answer has little to do with technology and everything to do with fear. Corporate leaders are quietly waiting to see who will be the first to pull the trigger. My discussions about Generative AI reveal a stark generational divide. Most people under 35 are convinced that AI is a reality, not a gimmick, and that the displac

The world is hurtling towards an inevitable AI dystopia in the very near future, according to Mo Gawdat, the former chief business officer of Alphabet’s moonshot factory, formerly known as Google X. “We will have to prepare for a world that is very unfamiliar,” Gawdat said in an interview on the “Diary of a CEO” podcast, adding that humanity’s key values like freedom, human connection, accountability, reality, and power are all facing a major disruption by AI.

OpenAI Usage Plummets in the Summer, When Students Aren't Cheating on Homework

futurism.com Unknown 2025-12-01 18:21:56

For years, teachers have been bashing their heads against the wall as students outsource their homework to large language model (LLM) chatbots like ChatGPT. The time-honored tradition of parenting-by-screen — grossly exacerbated by the rise of LLM chatbots — is now coming to a head with what many have called a "crisis in student literacy," as reading ability among children in the US hits all-time lows.

Following the rollout of OpenAI's latest GPT-5 model earlier this week, a certain user base was adamantly calling for the return of the previous GPT-4o model. Outspoken users complained about the writing quality of the updated model, with some even going so far as to grieve the loss of GPT-4o, which some said they considered a friend and confidant.

People returned to live in Pompeii's ruins, archaeologists say New evidence suggests people returned to live among the ruins of Pompeii after the ancient Roman city was devastated by a volcanic eruption. Archaeologists believe some survivors who could not afford to start a new life elsewhere returned to the site and may have been joined by others looking for a place to settle.
