Java to Strengthen Immutability of Final Fields

2025-03-31

To enhance the safety and performance of Java programs, the JDK plans to strengthen the immutability of final fields. Currently, deep reflection can modify final fields, which violates the original intention of the final keyword and limits JVM optimization. Future releases will default to prohibiting deep reflection from modifying final fields and will issue warnings. Developers can selectively enable modification of final fields using the `--enable-final-field-mutation` option, but it is recommended to avoid it as much as possible. This move aims to improve Java's "security by default" feature and maintain consistency with the design of record classes.

The Stack Unwinding Conundrum in Perf

2025-01-31
The Stack Unwinding Conundrum in Perf

Perf, a powerful performance analysis tool, uses PMU counter overflow interrupts to capture thread states for profiling. However, stack unwinding presents a challenge. Modern compilers omit frame pointers by default, making stack backtracing difficult. While recompiling with -fno-omit-frame-pointer is possible, it's expensive and can lead to system library incompatibilities. DWARF offers an alternative, but its complexity and performance overhead are substantial, leading Linus Torvalds to reject its use in kernel stack unwinding. Perf thus employs a compromise: copying only the top portion of the stack to userspace for unwinding. This limits stack size (65,528 bytes) but effectively balances performance and practicality.

France Slaps Apple with €150M Fine Over App Tracking Transparency

France's competition authority fined Apple €150 million for violating competition law with its App Tracking Transparency (ATT) framework. The authority argues that ATT disproportionately harms smaller publishers because Apple's own ad tracking requires only single consent, while others need double consent. While the fine is insignificant to Apple's revenue, Apple must modify ATT to comply. Apple maintains that ATT is consistent for all developers and enjoys broad support.

Sonic Hedgehog Protein: A Key Player in Embryonic Development

Sonic hedgehog protein (SHH), encoded by the SHH gene, is a crucial signaling molecule in embryonic development across humans and other animals. It plays a key role in regulating embryonic morphogenesis, controlling organogenesis and the organization of the central nervous system, limbs, digits, and many other body parts. SHH mutations can lead to holoprosencephaly and other developmental disorders. Abnormal SHH signaling activation in adult tissues has been implicated in various cancers. The discovery of the SHH gene stemmed from fruit fly experiments, with its name inspired by the video game character. SHH is vital in neural tube patterning, its concentration gradient determining the differentiation of various neuronal subtypes. Its role extends to lung development and has potential regenerative functions.
