Let us serve you, but don't bring us down

Summary: The Internet Archive experienced an hour-long outage due to tens of thousands of requests per second for its public domain OCR files from 64 virtual hosts on Amazon's AWS services. The Archive blocked the IP addresses of those hosts and got the service back up, but another 64 addresses started the same activity a couple of hours later, causing another hour-long outage. The Archive suggests that those wanting to use its materials in bulk should start slowly and ramp up and contact them if starting a large project. They also ask users not to bring them down in the process of using their services.

New Arm Cores Deliver Up to 40% Better Performance

Summary: Arm has announced its next-generation chip designs for mobile devices, the Total Compute Solution 2023 (TCS23), which includes new high-performance CPU cores for flagship phones. The new Arm Cortex-X4 offers 15% better performance using 40% less power compared to last year's X3. Additionally, the new "big" and "little" CPU core designs, Cortex-A720 and Cortex-A520 respectively, offer a 40% performance boost and 20-22% better power efficiency compared to last year's designs. The new Immortalis-G720 GPU offers a 14% improvement in total system efficiency and introduces Deferred Vertex Shading (DVS) technology. TCS23 also includes designs for other chip components, including the interconnect that links the cores and memory, which boasts 25% better latency. Arm has already produced a physical chip with TCS23 on TSMC N3E, which is intended to help its partners bring chips based on TCS
