Singing to babies is an important factor in helping them learn language, according to a study from the University of Cambridge.
The research indicates that infants initially understand language through rhythm and tone, rather than individual sounds.
The study challenges the belief that processing phonetic information is the primary aspect of language learning and suggests that dyslexia and developmental language disorder may be linked to rhythm perception.
The Reddit post in the Rust programming language subreddit outlines the rules and guidelines for posting, along with a discussion on the differences between Ada and Rust.
The post seeks insights from individuals with knowledge in both programming languages, focusing on topics like memory management, safety features, performance, and adoption rates of Ada in different industries.
The comments and discussion shed light on the strengths, limitations, and future prospects of both Ada and Rust as programming languages.
The Reddit discussion delves into the safety, features, and applications of programming languages such as Ada and Rust.
Ada is praised for its strong type system and contracts, while Rust is lauded for its focus on avoiding memory access errors.
Topics explored include dependent types, integrating Rust libraries with Ada, AI assistance in proof writing, language models, and the use of smart pointers in Rust.
The limitations and suitability of different languages for safety-critical and real-time applications are thoroughly examined.
The discussion provides contrasting opinions on the effectiveness and usefulness of various programming languages.
Scientists have found that fiber optic cables can pick up the sound of cicadas, leading to a potential new method for monitoring insect populations.
Using distributed acoustic sensing (DAS), researchers can analyze the light bouncing back from a laser fired through the cables to detect disturbances caused by loud sounds or seismic activity.
This technique could allow entomologists to remotely monitor cicadas and collect data on their population sizes and locations, using the already abundant fiber optic cables. However, monitoring quieter insect species with DAS may be more challenging.
Fiber optic cables can be utilized as sensors to detect bends and gather information about them in applications like intrusion detection and vibration monitoring.
Optical time domain reflectometers (OTDRs) are commonly employed to measure reflections in fiber optic cables, but uncertain cable speed can affect the accuracy of these measurements.
Various factors, such as twist rates in the cables, can contribute to the uncertainty in cable speed and affect the accuracy of the sensing technology.
Users are experiencing difficulty signing in on office.com using Firefox browser with a FIDO2 key, according to a bug report.
The severity level of the bug is stated as low, and Microsoft has been notified about the issue.
The bug remains unresolved, and efforts are underway to prompt Microsoft to address it, with multiple users verifying that the problem persists. The bug report also references Microsoft's authentication systems as complex and inconsistent.
Users are frustrated with Microsoft's login system on Firefox and suspect anti-competitive behavior and intentional blocking by Microsoft.
Complaints include Microsoft's lack of quality assurance and technical support, as well as navigation and compatibility issues with certain browsers.
There is a debate on whether Microsoft should continue to support minority browsers like Firefox, with some emphasizing inclusivity, while others discuss the adoption of Chrome's user-agent string to avoid compatibility issues.
The author shares their experience using clang to compile C++ programs on a Raspberry Pi B+.
Binaries built with clang cannot run on the B+ due to a default behavior change.
The author identifies a workaround by specifying the target architecture, but questions why this default behavior change went unnoticed and suggests that older Raspberry Pi models are not widely used anymore.
There was a discussion about compatibility issues between the Clang compiler and the original Raspberry Pi B+ due to its older ARM1176 core.
A bug in the LLVM compiler was resolved by specifying the target as armv6.
The conversation also touched upon the challenges of supporting old hardware in Linux distributions, the concept of free software, and emulating ARM64 on x86_64 using QEMU and Docker. Properly configuring the default image for the toolbox container was highlighted as crucial.
