Try attaching any monitor above 1920x1080 via HDMI. So if the cable is known to be good, the computers in question have all "HDMI 2.0 4k" in big letters in their specs, all should work, right? Mwahahaha.

The particular case on my disk right now: EDID and DDC properly report 1920x1200 (native), 1920x1080, 1600x1200, etc., yet it fails to work in the first mode. 1920x1200 needs HDMI 1.4 bandwidth, the two other HDMI 1.3. The same monitor, the same cable work with some computers, fail with others. Hrm.

My low-res monitors are DVI, which is supposed to be carried over HDMI (same protocol), but guess what? It's also random which computers they work with.

Meanwhile, in the DP land, I have yet to see my first failure. But sometimes I need HDMI for $REASON. :/

Submission + - MIT chemical engineers develop new way to separate crude oil (thecooldown.com)

fahrbot-bot writes: The Cool Down is reporting that a team of chemical engineers at the Massachusetts Institute of Technology has invented a new process to separate crude oil components, potentially bringing forward a replacement that can cut its harmful carbon pollution by 90%.

The original technique, which uses heat to separate crude oil into gasoline, diesel, and heating oil, accounts for roughly 1% of all global energy consumption and 6% of dirty energy pollution from the carbon dioxide it releases.

"Instead of boiling mixtures to purify them, why not separate components based on shape and size?" said Zachary P. Smith, associate professor of chemical engineering at MIT and senior author of the study, as previously reported in Interesting Engineering.

The team invented a polymer membrane that divides crude oil into its various uses like a sieve. The new process follows a similar strategy used by the water industry for desalination, which uses reverse osmosis membranes and has been around since the 1970s.

The membrane excelled in lab tests. It increased the toluene concentration by 20 times in a mixture with triisopropylbenzene. It also effectively separated real industrial oil samples containing naphtha, kerosene, and diesel.

Likewise with PCI 4.0 cards in a PCI 3.0 motherboard:
[ 0.768734] [ T1] pci 0000:43:00.0: 126.016 Gb/s available PCIe bandwidth, limited by 8.0 GT/s PCIe x16 link at 0000:40:03.1 (capable of 252.048 Gb/s with 16.0 GT/s PCIe x16 link)
or in a physically-x16-really-x4 slot:
[ 0.777737][ T1] pci 0000:09:00.0: 31.504 Gb/s available PCIe bandwidth, limited by 8.0 GT/s PCIe x4 link at 0000:00:03.1 (capable of 126.024 Gb/s with 16.0 GT/s PCIe x8 link)

The second card has same problem as yours, when in a real x16 slot it'd use only 8 lanes despite physically having the connectors.

Submission + - Caffeine Has a Weird Effect on Your Brain While You're Asleep (sciencealert.com) 1

alternative_right writes: Caffeine was shown to increase brain signal complexity, and shift the brain closer to a state of 'criticality', in tests run by researchers from the University of Montreal in Canada. This criticality refers to the brain being balanced between structure and flexibility, thought to be the most efficient state for processing information, learning, and making decisions.

Submission + - What Will Universities Look Like Post-ChatGPT? (cameronharwick.com) 5

An anonymous reader writes: Lots of people are sounding the alarm on AI cheating in college.

Who could resist a tool that makes every assignment easier with seemingly no consequences? After spending the better part of the past two years grading AI-generated papers, Troy Jollimore, a poet, philosopher, and Cal State Chico ethics professor, has concerns. “Massive numbers of students are going to emerge from university with degrees, and into the workforce, who are essentially illiterate,” he said. “Both in the literal sense and in the sense of being historically illiterate and having no knowledge of their own culture, much less anyone else’s.”

Economist Cameron Harwick says it's on professors to respond, and it's going to look like relying more on tests and not on homework—which means a diploma will have to be less about intelligence and more about agency and discipline.

This approach significantly raises the stakes of tests. It violates a longstanding maxim in education, that successful teaching involves quick feedback: frequent, small assignments that help students gauge how they’re doing, graded, to give them a push to actually do it.... Unfortunately, this conventional wisdom is probably going to have to go. If AI makes some aspect of the classroom easier, something else has to get harder, or the university has no reason to exist.

The signal that a diploma sends can’t continue to be “I know things”. ChatGPT knows things. A diploma in the AI era will have to signal discipline and agency – things that AI, as yet, still lacks and can’t substitute for. Any student who makes it through such a class will have a credible signal that they can successfully avoid the temptation to slack, and that they have the self-control to execute on long-term plans.


Submission + - Jared Isaacman pre-fired because of Musk connection (theregister.com)

Mirnotoriety writes: “Jared Isaacman, former NASA Administrator nominee, has shared how the US space agency might have looked under his leadership and blamed his connections with Elon Musk for the abrupt withdrawal of his nomination.”

"I don't like to play dumb ... I don't think that the timing was much of a coincidence ... There were other things going on on the same day."

‘There were indeed. Elon Musk's departure from the Department of Government Efficiency was also announced. "Some people had some axes to grind," said Isaacman, "and I was a good visible target."’

Submission + - Stanford is a case study in how Beijing infiltrates U.S. universities (washingtonpost.com)

schwit1 writes: Student reporters at Stanford University revealed China’s spying methods using Chinese nationals.

The Trump administration is revoking visas for Chinese students “with connections to the Chinese Communist Party or studying in critical fields” and revising its “visa criteria to enhance scrutiny of all future visa applications” for students from China and Hong Kong.

This is both necessary and long overdue. For years, China has been engaged in a systematic effort to target U.S. universities, using Chinese students to conduct extensive espionage and intellectual property theft on elite campuses across the United States — which has helped fuel China’s technological and military growth.

To understand how China uses its students as spies, read the stunning investigative report published last month by Stanford Review reporters Garret Molloy and Elsa Johnson in which they documented the infiltration of Stanford University by the Chinese Communist Party. “The CCP is orchestrating a widespread academic espionage campaign at Stanford,” Johnson told me and my co-host, Danielle Pletka, in a recent podcast interview. “Stanford is in the heart of Silicon Valley,” she added, “and that’s a huge incentive for China.”..

Molloy, an economics major, visited China last summer and was shocked to meet with many members of the CCP who were educated at Stanford. “We’re educating the head of the Chinese [securities and exchange commission], we’re educating the head of Beijing’s tariff negotiators. I’m meeting all these people and they all say ‘I work for the Chinese Communist Party in a really high role. I hope that China beats the U.S. And I also went to Stanford for my undergraduate and master’s degree.’ And I’m putting this together and I’m saying it’s shocking that we are educating such high-level Communist Party officials. What’s going wrong here?”

It’s a fair question — one of many for which the Trump administration plans to get answers.

And it's not just Stanford.
