If you’re watching consecutive episodes of a series you can always just download them to your phone before you head to work. Not really viable if you hop around a lot, though.
Seconded, that beast (well, one of its predecessors) got me through college on the included toner cartridge alone and it’s still kicking
“Owning a car = freedom”
“You need a big truck/SUV to haul things” (it’s just a coincidence that people drove much smaller cars before a multibillion dollar deluge of advertising)
“It’s consumers’ responsibility to reduce plastic pollution by recycling, and recycling is effective” (whoever came up with this one belongs in the PR scumfuck hall of fame)
Original Phoronix article which has all the individual benchmarks—weird that they didn’t link to it
There’s a variable that contains the number of cores (called cpus
) which is hardcoded to max out at 8, but it doesn’t mean that cores aren’t utilized beyond 8 cores–it just means that the scheduling scaling factor will not change in either the linear or logarithmic case once you go above that number:
/*
* Increase the granularity value when there are more CPUs,
* because with more CPUs the 'effective latency' as visible
* to users decreases. But the relationship is not linear,
* so pick a second-best guess by going with the log2 of the
* number of CPUs.
*
* This idea comes from the SD scheduler of Con Kolivas:
*/
static unsigned int get_update_sysctl_factor(void)
{
unsigned int cpus = min_t(unsigned int, num_online_cpus(), 8);
unsigned int factor;
switch (sysctl_sched_tunable_scaling) {
case SCHED_TUNABLESCALING_NONE:
factor = 1;
break;
case SCHED_TUNABLESCALING_LINEAR:
factor = cpus;
break;
case SCHED_TUNABLESCALING_LOG:
default:
factor = 1 + ilog2(cpus);
break;
}
return factor;
}
The core claim is this:
It’s problematic that the kernel was hardcoded to a maximum of 8 cores (scaling factor of 4). It can’t be good to reschedule hundreds of tasks every few milliseconds, maybe on a different core, maybe on a different die. It can’t be good for performance and cache locality.
On this point, I have no idea (hope someone more knowledgeable will weigh in). But I’d say the headline is misleading at best.
I remember being wowed by Beowulf (which I think was the first high profile 3D movie in the most recent wave), and I also enjoyed Avatar in 3D. Other than those two movies I found that 3D detected detracted from the overall experience and I quickly stopped attending 3D showings.
edit: realized I made a typo three days later…embarrassing

After three decades of distinguished work in the United States, world-leading cancer researcher Sun Shao-Cong has returned to China to establish a new lab in Beijing, following what a source said were investigations of him by the US government.
Sun joined the Chinese Institutes for Medical Research (CIMR) as a distinguished investigator in July, he told the Post via email last week.
Known for his pioneering research on T cells – white blood cells that fight infections and destroy abnormal cells – Sun’s roles in the US have included director of the Centre for Inflammation and Cancer at the University of Texas MD Anderson Cancer Centre in Houston from 2014 to 2022.
Since then, he has focused on recruiting for his lab and a new immunology institute. He said his team will study the molecular mechanisms of anticancer immunity, autoimmunity and inflammatory diseases, with an emphasis on T cell function and regulation.
Sun was removed from his position in 2022 after being investigated for his ties to China, a source told the Post on condition of anonymity.
Details of the investigations remain unclear, but MD Anderson was among the first institutions to dismiss China-born researchers after warnings from the National Institutes of Health (NIH), one of their major funders, about potential theft of US scientific research.
In 2018, the NIH and the Department of Justice launched separate probes into alleged economic espionage and technology theft from China. But the investigations sparked controversy over concerns about racial profiling.
By April 2019, MD Anderson had expelled three unnamed Chinese researchers, citing conflicts of interest or undisclosed foreign income, the Houston Chronicle reported.
During a career spanning decades, Sun has received more than US$24 million from NIH-affiliated institutes, including the National Institute of Allergy and Infectious Diseases and the National Cancer Institute, according to the NIH RePORTER website.
In 2012, Sun was named a Cheung Kong Scholar, a prestigious talent recruitment programme supported by China’s Ministry of Education and the Li Ka Shing Foundation to foster student training and research collaboration at Shanghai Jiao Tong University.
Sun earned a bachelor’s degree in biology from Hubei University and a PhD in microbiology from Stockholm University. He moved to the US for a postdoc position at the University of California, San Francisco in 1992.
He then conducted T cell-focused leukaemia research at Pennsylvania State University’s Hershey Medical Centre, and rose to distinguished professor status in 2007 before transitioning to MD Anderson.
Sun’s research employs cutting-edge immunological and molecular biology techniques, including mouse models, to explore T cell activation, functionality, and the impact of the tumour micro-environment, according to a July job posting on CIMR’s official WeChat account.
“Professor Sun has made numerous far-reaching contributions to this field and is an internationally recognised leader,” the post said.
Although the Department of Justice’s China Initiative was terminated in 2022, US government agencies have continued to scrutinise China-born researchers.
Most investigations have failed to reach court, and a small number of prosecutions were for charges unrelated to the espionage the probes sought to address.
