Impact of Extremely Low Temperatures on 5nm SRAM Array Size and Performance

New research explores the effects of extremely low temperatures (down to 10K) on the size and performance of 5nm FinFET SRAM arrays. Researchers found that at cryogenic temperatures, the maximum array size is limited by wordline parasitics, not leakage current, and performance is governed by both bitline and wordline parasitics. This has significant implications for future low-power, high-performance computing, offering valuable insights for optimizing SRAM arrays in extremely cold environments.

Chirping Cosmic Waves Detected Far From Earth

Scientists have detected unusual cosmic waves, sounding like birds chirping, in a region far beyond previous observations. Using NASA's Magnetospheric Multiscale (MMS) satellites, researchers picked up these 'chorus waves'—bursts of plasma—over 62,000 miles from Earth. These waves, when converted to audio, resemble high-pitched bird calls. The unexpected location of these previously observed waves in a stretched-out region of Earth's magnetic field raises new questions about their formation. The research was published in Nature.

Federal Court Rules Backdoor Searches of 702 Data Unconstitutional

A federal district court has ruled that backdoor searches of databases containing Americans' private communications, collected under Section 702, typically require a warrant. This landmark ruling, following over a decade of litigation, rejects the government's claim that such searches can be conducted warrantlessly. Organizations like the EFF have long argued this practice is unconstitutional, and the court's decision is a significant victory for privacy rights. The ruling calls for Congressional reform of Section 702 to prevent future abuses.

Revamping the ACM Student Research Competition: A Focus on Feedback

While the programming languages community boasts mentoring initiatives like PLMW, SIGPLAN-M, and PLTea, a crucial piece is missing: guidance on presenting research. The authors argue that the ACM Student Research Competition (SRC), while intending to help, suffers from a competition-focused approach that overshadows its feedback mechanisms. This leaves junior researchers lacking the crucial skills of presenting their work effectively. The proposed solution is to refocus the SRC on providing high-quality feedback from experts, including increased expert reviewers, detailed feedback, and archiving extended abstracts. This aims to improve student presentation skills and increase the visibility of their research.

The Secret Spy Satellite That Helped Win the Cold War

In the 1970s, the rise of the Soviet Navy posed a significant threat to the US. To counter the emergence of powerful new Soviet warships, the top-secret Parcae satellite program was launched. Developed by the US Naval Research Laboratory, Parcae provided real-time location data on Soviet vessels, drastically reducing the time between signal interception and intelligence reporting to mere minutes. This near-instantaneous intelligence was crucial for military decision-making. Employing multiple satellites working in concert and advanced computer systems to process massive amounts of data, Parcae helped maintain the strategic balance during the Cold War. Its technology continues to influence modern satellite signals intelligence systems.

Thread Safety Nightmare: A Mysterious Crash on ARM64, Even with Safe Rust

Thread Safety Nightmare: A Mysterious Crash on ARM64, Even with Safe Rust

While porting network I/O code from Python to Rust in EdgeDB, a mysterious crash on ARM64 platforms emerged. Initially suspected to be a deadlock, the root cause turned out to be thread-unsafe behavior in the `setenv` and `getenv` functions. On ARM64, the `openssl-probe` library uses `setenv` to set environment variables, while another thread concurrently calls `getenv`. This reallocates the `environ` array, leading to a crash. The solution involved switching reqwest's TLS backend from rust-native-tls to rustls. This highlights how even in memory-safe Rust, interactions with the C standard library can still introduce thread safety issues.

Rust: Investigating a Mysterious OOM

Qovery's engine-gateway, a Rust service, experienced unexpected out-of-memory (OOM) crashes. Monitoring showed stable memory usage before abrupt restarts. The culprit? The anyhow library, when backtraces are enabled, captures a backtrace for every error. Symbol resolution, only triggered when printing errors in debug mode (`{:?}`), caused massive memory consumption. Setting environment variables `RUST_BACKTRACE=1` and `RUST_LIB_BACKTRACE=0` to enable backtraces only on panic solved the issue. This highlights how monitoring can be deceptive and the importance of thorough library documentation review.
