Language Skills, Not Math, Are Key to Learning to Code

A University of Washington study challenges conventional wisdom about learning to program. Researchers found that the speed and proficiency of learning Python are more strongly correlated with language aptitude and problem-solving skills than with mathematical ability. Using behavioral tests and EEG data, the study demonstrated that language skills significantly impact learning speed, surpassing the influence of math skills. This has crucial implications for programming education and talent recruitment, challenging the traditional view of programming as a purely math-intensive field and suggesting that women may be underestimated in the field.

NATS Trademark Dispute Escalates: Synadia Reclaims Project, CNCF Fights Back

A legal battle is brewing over the trademark and marketing of the widely used NATS message server. After Synadia, the former owner, reclaimed the software from the Cloud Native Computing Foundation (CNCF), the CNCF is now seeking to have the NATS trademark and logo deleted. The CNCF argues Synadia relinquished all rights in 2018 and must adhere to agreements. Synadia counters that the CNCF failed to foster community involvement, with most contributions originating from Synadia, and proposes switching NATS to a Business Source License (BSL). The CNCF rejects the BSL as non-open source, emphasizing its commitment to open-source values. The core dispute revolves around ownership, trademark rights, and licensing, potentially leading to a project fork similar to the Terraform/OpenTofu split.

C++26: A Giant Leap for Compile-Time Standard Library Features

2025-05-01

C++26 is set to revolutionize compile-time programming with a massive boost to constexpr support in the standard library. Several proposals (P2562R1, P1383R2, P3074R7, P3372R2, P3508R0, P3369R0) bring stable sorting algorithms, and functions, improved union rules, nearly all containers and adaptors, and specialized memory algorithms into the constexpr fold. This significantly enhances compile-time capabilities, allowing, for example, compile-time sorting of constexpr containers. While std::hive and std::hash remain excluded due to limitations, C++26 promises a dramatic expansion of compile-time programming possibilities.

macOS Malware Scans Slowing App Launches

2025-05-01

Developer Jeff Johnson discovered that macOS's syspolicyd process performs malware scans on applications, causing slow launches for apps like Xcode, FileMerge, and Google Chrome. These scans consume significant CPU resources, leading to noticeable delays even for small apps. Johnson suspects syspolicyd scans not only the app itself but also its linked libraries. He resolved the issue by disabling System Integrity Protection (SIP), but this also disables some system services. The article explores the root cause and expresses frustration with this seemingly unnecessary security measure, preferring background scans to foreground interruptions.

AI Writes Code, AI Reviews It? Is That Silly?

Daksh, co-founder of Greptile, discovered that an AI code generation tool, Devin, was submitting more pull requests than any human engineer. This raises the intriguing question: should AI-generated code be reviewed by AI itself? While LLMs are stateless, each call is independent, this doesn't mean AI perfectly reviews its own code. AI-generated code, while boosting efficiency, may introduce bugs humans struggle to find. Research shows AI is more effective than humans at finding certain types of bugs, although its accuracy still needs improvement. Ultimately, the article argues that while not perfect, AI code review is more effective than humans at finding specific bug types introduced by AI itself.

Slow Mac App Launches: Malware Scan or Hash Cache Miss?

2025-05-01

Blogger Jeff Johnson discovered last year that slow Mac app launches are due to malware scanning by the syspolicyd process. However, blogger Howard Oakley disagrees. Johnson uses spindumps to refute Oakley, showing the malware scan occurs during dlopen when loading dynamic libraries. Oakley claims the slow launches are due to SHA-256 hash cache misses for files in the Frameworks folder. Johnson argues Oakley's theory lacks evidence and ignores the fact that universal binaries contain two architectures, making Oakley's hash calculation time estimates inaccurate. The core of this debate lies in different interpretations of system logs and process snapshots, and differing understandings of caching mechanisms.
