    In parts of China (like Beijing) the word for farmer is a pretty bad slur* (maybe they need another reminder)

    * I don’t speak Chinese so comrades please correct me or weigh in

    Most gear is still air-cooled but that’s changing pretty quickly

    Liquid cools like 3000x more efficiently than air, something like that

    Also see ideas like this: https://www.ibm.com/blogs/research/2017/08/beat-heat-3d-chip-stacks-icecool/

    I think IBM still has a 5Ghz mainframe chip out there but since multicore era frequency is mostly ~2-3 Ghz

    electron tunneling is no match for Moore’s law…

    I’m talking shit, but yes they do do something… state of the art is 3nm/5nm

    The -nm is just marketing nowadays, not tied to a physical characteristic, so the smallest feature size isn’t really 3nm or 5nm, etc anymore but each node shrink is still meaningful and “smaller than the last one”

    And to your point, chips be going up to 1000 watts! (Invest in liquid cooling and short the planet.)

    2022 Panel Discussion: Facilitating Advanced Material Development for the Acceleration of Hypersonic Capabilities Accelerating hypersonic capabilities has been a major priority for DoD’s research and engineering efforts to stay ahead of rapidly modernizing adversaries. The extent to which hypersonic weapons are adopted for the future fight depends on a variety of technological limitations. Currently, DoD is working to advance alloys, coatings, and structures that can withstand the intense heat of hypersonic environments while also being stronger but lighter in weight. This session will ask experts from AFRL, NASA, Industry & Academia to provide their insight into the acceleration of hypersonic capabilities. Panelists will offer their perspective on the following topics:

    Subsequent Challenges and Solutions to Developing Hypersonic Weapons
    Advanced Materials Required for the Development of Hypersonic Weapons
    Developing Functional and Resilient Hypersonic Capabilities

    Panelists: Dr. Charles D. Ormsby, Chief, Manufacturing and Industrial Technologies Division, Materials and Manufacturing Directorate, AFRL
    Dr. David Glass, Senior Technologist; Technical Advisor, Hypersonic Technology Project, NASA Langley Research Center
    Dr. David Maranchi, Program Area Manager, Signature, Electromagnetics, and Energy, JHU/APL
    Christina Bain, Director (Acting), Hypersonics and Advanced Materials, Lockeed Martin

    Moderator:
    Dr. Thomas Corke
    Director, Hypersonic Systems Initiative
    University of Notre Dame

    excerpts from Foreign Ministry Spokesperson Wang Wenbin’s Regular Press Conference on September 1, 2022

    China News Service: On August 30, Prime Minister of Pakistan Shehbaz Sharif thanked China for its assistance to his flood-affected country. Disasters caused by the heavy rain have resulted in the death of 1,136 people and more than 33.04 million people are affected by the floods. Can you update us on China’s assistance to Pakistan?

    Wang Wenbin: Since the floods hit Pakistan, China has been closely following the situation. We responded immediately and made every effort to provide relief assistance. The spokesperson of the foreign ministry shared relevant information on August 29.

    On the same day, President Xi Jinping sent a message of sympathy to the Pakistani President Arif Alvi over the severe floods hitting the country. He noted that as all-weather strategic cooperative partners and “ironclad” friends, China and Pakistan have been sharing weal and woe, rendering each other assistance in times of need. China will continue to provide Pakistan with urgently-needed help and support the Pakistani side’s disaster relief work. Premier Li Keqiang also sent a message of sympathy to Prime Minister Shehbaz Sharif.


    Reuters: American chip designer Nvidia Corp said on Wednesday that US officials told it to stop exporting two top computing chips for Artificial Intelligence to China. And this move could cripple Chinese firms’ ability to carry out advance work like image recognition. Does the foreign ministry have any comment on this?

    Wang Wenbin: What the US has done is typical “sci-tech hegemony”. The US has been stretching the concept of national security and abusing state power. The US seeks to use its technological prowess as an advantage to hobble and suppress the development of emerging markets and developing countries. This violates the rules of the market economy, undermines international economic and trade order and disrupts the stability of global industrial and supply chains. China firmly rejects it.

    The US politicizes, instrumentalizes and weaponizes tech and trade issues, and engages in tech blockade and decoupling in an attempt to monopolize the world’s advanced technologies, perpetuate its hegemony in the sci-tech sector, and damage the closely-knit global industrial and supply chains. Such moves will not succeed.
