Nike, the sportswear company named after the Greek goddess of victory, is losing its spot in the top 100 U.S. companies for the first time in nearly two decades. The athletic apparel giant lost over $200 billion in market cap since its all-time high in 2021, a near 80% drop in just the five years that have passed, and a plummet so severe that the once mighty company…

**What Youโll Learn**: Investigating JPEG XL's place as a Web image codec. Why? JPEG XL is a technically impressive image codec; it is a definitive upgrade over JPEG, more versatile than WebP, and well-equipped to serve use cases beyond the Web. However, it was famously rejected from Chrome in 2023. Because this happened to a royalty-free, flexible, compression-efficient codec from the JPEG Committee that was receiving attention from large companies, the decision didn't land well with many. Recently, a JPEG XL decoder in Rust has made its way…

(Audience applauds.) Doctorow: ((27.0)) Thank you. ((32.0)) So, when I speak in places where the first language of the nation is not English, there is a disclaimer and an apology, because I'm one of nature's fast talkers. When I was at the United Nations at the World Intellectual Property Organization, I was known as the "scourge" of the simultaneous translation…

**What Youโll Learn**: I have a difficult confession to makeโโโa shameful incident that I have never spoken of, even to those closest to me. Late one night in my first year at university and having found computer science to be my lifeโs calling, I was in the back of the large computer science lab, talking with some fellow underclassmen. We were snidely decrying the lack of technological understanding in the broader population, with the kind of arrogance and hubris that youth and precociousness can uniquely summon. Somewhere…

It appears to have actually solved it, and the solution is quite embarrassing for humans in hindsight. At the end of Urquhartโs Logopandecteision is a cryptogram consisting of two lines of 32 numbers each, called the Cyphral Distich. A cryptogram is a short message deliberately encoded so it canโt be read without knowing the rule that produced it. Here the entire puzzle input is these 64 numbers, and the…

**What Youโll Learn**: Flawed Routers Flood University of Wisconsin Internet Time Server ABSTRACT In May 2003, the University of Wisconsin - Madison found that it was the recipient of a continuous large scale flood of inbound Internet traffic destined for one of the campus' public Network Time Protocol (NTP) servers. The flood traffic rate was hundreds-of-thousands of packets-per-second, and hundreds of megabits-per-second. Subsequently, we have determined the sources of this flooding to be literally hundreds of thousands of real Internet hosts throughout the world. However, rather than having…

For Costco members, Kirkland Signature synthetic oil has made the DIY approach particularly attractive thanks to its relatively low price. That bargain has suddenly become much less compelling. According to The Auto Wire, a 10-quart case of Kirkland Signature full-synthetic motor oil is now listed at $57.99, up from prices that hovered in the mid-$30 range for years. The price increase isnโt the only unusual development. Costco…

Persistent attack traffic coming from three particular IPs, with the strange thing being that they were arriving with Host or Referer headers from pool-ntp.tesla.com, carried Assetnote user agents, and were trying to SSRF me to Assetnote callback URLs: 35.168.63.24 - - [13/Sep/2026:01:14:31 -0700] "GET…
