WebAssembly is a low-level bytecode supported by all major web browsers, designed for performance parity with native code especially for languages like C and C++. Previous evaluations showed WebAssembly to be only about 10% slower than native code, but this was limited to small scientific kernels. A new extension called Browsix-Wasm enables the running of unmodified Unix applications compiled to WebAssembly directly in browsers. Large-scale benchmarks reveal a significant performance gap, with applications compiled to WebAssembly running 45-55

The text discusses the challenges of naming variables and concepts in programming, referencing a quote by Phil Karlton that highlights cache invalidation and naming as two difficulties in computer science. It emphasizes the importance of using consistent and clear naming conventions to improve code readability and maintainability. Suggestions include using standard names like "isActive" for booleans, avoiding negative names that can cause confusion, and steering clear of ambiguous abbreviations. It also advises choosing a consistent spelling (preferably US spelling) and avoiding overly

Startups have traditionally prioritized growth over profitability, often viewing profitability as a lack of ambition. However, this perspective is flawed. Achieving profitability allows founders to control their business's destiny, relying less on investors and maintaining focus on their vision. Paul Graham's concept of "ramen profitability" highlighted that reaching a level where a startup can sustain itself without external funding makes it more appealing to investors. The current landscape allows startups to not only achieve ramen profitability but also traditional profitability while growing quickly. The author

Google has implemented developer verification to prevent the installation of unregistered APKs, enhancing security by linking each APK to its developer, similar to the Play Store. This change follows Google's decision to make Android development private, complicating tracking of their actions in the Android Open Source Project (AOSP). The verification process poses challenges for small developers, as hobbyist licenses could limit app distribution based on install numbers. The writer worries that APKs relying on legacy permissions may not pass security checks and emphasizes the difficulties

The RFD describes a specific kind of deadlock in asynchronous Rust programming called "futurelock." This occurs when a resource owned by Future A is needed for Future B to continue, but the task managing both Futures is not actively polling Future A. The issue was highlighted by Oxide in a GitHub issue. An example program is provided, showcasing a predictable deadlock scenario. The program involves a background task that holds a lock for 5 seconds, during which two Futures are being awaited. One Future

The release of version 0.7.7 of C3 introduces significant improvements in usability, specifically with changes to the vector ABI, which now handles vectors as arrays in function calls and structs. This eliminates the need for conversion between C structs and SIMD vectors, streamlining the development process. Additionally, alignment for vectors now matches that of structs and arrays, simplifying their usage. New features include a splat operator for initializer default values, implicit subscript dereferencing with the ability to use the .[

This module focuses on browser and network fingerprinting, which are crucial for web automation and detection systems. Fingerprinting combines elements from network protocols, cryptography, and behavioral analysis to identify and track devices and users without traditional identifiers like cookies or IP addresses. Each browser connection reveals various characteristics, such as TCP options order, GPU rendering patterns, and JavaScript execution timings, which collectively form a unique fingerprint for a device or browser. For automation engineers and privacy-conscious users, understanding fingerprinting is vital for creating
