$MU $SNDK $EWY Every few months a paper drops claiming AI needs less memory. This is that paper. There is no such thing as a free lunch. Compressing KV cache in controlled benchmarks is not the same as scaling it universally to every user, task, and platform in the world. Accuracy collapse is real at scale. As expected from a research paper, the downsides never make the headlines. Remember Titans Architecture? Google said it would make memory usage more efficient. Didn't move the needle. If anything, it drove more HBM demand. Jevons Paradox. What did Deepseek do? What's memory demand today? You be the judge. HBM is still the primary fuel for AI training. That does not change. The paper targets long-context inference which relies on a full memory stack: HBM for speed, server DRAM and NAND for capacity and storage. When inference runs, memory spills from HBM into conventional DRAM and NAND. HBM stays fully utilized. At best, this research reduces the spill in a controlled workload, IMO.

$PLTR and Anduril are building the software layer for the $185B “Golden Dome” missile defense system. The platform will serve as the command-and-control brain linking radars, sensors and weapons into a unified network.

川普刚刚证实：伊朗急着求和。 马可·卢比奥和JD·万斯已经接管了谈判桌。 为什么突然低头？ 看看他们手里还剩什么。 海军瘫痪。 空军瘫痪。 连防空系统和导弹都打光了。 最致命的是，指挥部的通讯网全面中断。 现在连互相通个话都做不到。 如果你每天看主流媒体的报纸。 你会以为这是一场势均力敌的苦战。 事实呢？ 美军战机现在就在德黑兰上空如入无人之境。 是德黑兰，不是边境。 今天美军本来锁定了世界上最大的发电厂之一。 只要瞄准正确位置一发导弹。 整座工厂就会彻底瘫痪。 开火前一刻，行动叫停。 因为对方已经乖乖坐在了谈判桌前。 以前华盛顿的政客怎么谈和平？ 送去一飞机一飞机的美元现金。 对独裁者把石油卖给中共换取续命钱视而不见。 让纳税人买单，让全球主义者分赃。 现在的筹码是悬在头顶的炸弹。 如果那座发电厂真的化为废墟。 德黑兰的政客还拿什么过冬？

More than 800 Rutherford engines have been launched to space and this year we plan to exceed 1,000 total. 3D printing helped to make that scale possible. Like Rutherford, Neutron's Archimedes engine features 3D printed parts, including turbo pump housings, thrust chamber, valve housings, and engine structural components.
