The Media Can't Stop Propping Up Elon Musk's Phony Supergenius Engineer Mythology

By Karl Bode
"CEO said a thing!" journalism is now utterly pervasive, and includes parroting billionaire and CEO claims with a total disregard for whether or not anything being said is actually true.
Despite the fact Musk has increasingly shown himself to be a conspiratorial white supremacist with a head full of room temperature butterscotch, the U.S. press is demonstratively un…

The Media Can't Stop Propping Up Elon Musk's Phony Supergenius Engineer Mythology
One of my favorite trends in modern U.S. infotainment media is something I affectionately call "CEO said a thing!" journalism. "CEO said a thing!" journalism generally involves a press outlet parroting the claims of a CEO or billionaire utterly mindlessly without any sort of useful historical context as to

Lucky SHD 400 (6x6) English Alt Text: A black and white image showing a glass door with curtains behind it and a rental sign posted inside. The sign, written in Chinese, reads “房屋出租 联系电话: 13714600877,” offering the property for rent with a contact number. The door is part of a tiled building facade, and large leafy plants partially obscure the lower portion. The scene conveys a quiet urban moment, with the sign as the focal point. 中文替代文本： 一张黑白照片，展示一扇玻璃门，门后是窗帘，门内贴有一张出租告示。告示用中文写着：“房屋出租 联系电话: 137…
Lucky SHD 400 (6x6) English Alt Text: A black and white photo of a single traffic cone placed on a wooden deck in front of a building. The cone is labeled with English and Chinese text reading “APPROPRIATE PARKING P 专用车位,” indicating a designated parking space. The background includes a concrete and wood-paneled wall, a window reflecting light, and a hanging lamp. The composition emphasizes contrast and texture, with the cone standing out against the muted tones of the deck and building. 中文替代文…
Lucky SHD 400 (6x6) English Alt Text: A black and white street scene in a bustling commercial area of a Chinese city. Storefronts with Chinese signage line the right side, including “北京悦百信亿得发超市” and “首都农资.” People gather around market stalls, and vehicles including a three-wheeled truck labeled “DA7” move through the street. Overhead wires crisscross above, and a cylindrical water tower rises in the background. The image captures everyday urban life with rich detail and movement. 中文替代文本： 一张黑白街…
Lucky SHD 400 (6x6) English Alt Text: A monochrome photograph of a rustic wall constructed from large rounded stones, bricks, and a wooden panel. The wooden section is framed by an arched brick structure, possibly a sealed window or decorative feature. Climbing plants grow along the left side, adding organic texture. The image highlights the interplay between natural and man-made materials, with strong contrasts in shape and surface. 中文替代文本： 一张黑白照片，展示一面由大块圆石、砖块和木板构成的乡村风格墙面。木板嵌在一个砖砌的拱形框架中，可能是封闭…

Perfect Network Resilience in Polynomial Time

Abstract: Modern communication networks support local fast rerouting mechanisms to quickly react to link failures: nodes store a set of conditional rerouting rules which define how to forward an incoming packet in case of incident link failures. The rerouting decisions at any node $v$ must rely solely on local information available at $v$: the link from which a packet arrived at $v$, the target of the packet, and the incident link failures at $v$. Ideally, such rerouting mechanisms provide perfect resilience: any packet is routed from its source to its target as long as the two are connected in the underlying graph after the link failures. Already in their seminal paper at ACM PODC '12, Feigenbaum, Godfrey, Panda, Schapira, Shenker, and Singla showed that perfect resilience cannot always be achieved. While the design of local rerouting algorithms has received much attention since then, we still lack a detailed understanding of when perfect resilience is achievable.
This paper closes this gap and presents a complete characterization of when perfect resilience can be achieved. This characterization also allows us to design an $O(n)$-time algorithm to decide whether a given instance is perfectly resilient and an $O(nm)$-time algorithm to compute perfectly resilient rerouting rules whenever it is. Our algorithm is also attractive for the simple structure of the rerouting rules it uses, known as skipping in the literature: alternative links are chosen according to an ordered priority list (per in-port), where failed links are simply skipped. Intriguingly, our result also implies that in the context of perfect resilience, skipping rerouting rules are as powerful as more general rerouting rules. This partially answers a long-standing open question by Chiesa, Nikolaevskiy, Mitrovic, Gurtov, Madry, Schapira, and Shenker [IEEE/ACM Transactions on Networking, 2017] in the affirmative.
