In Ruby 3.5, object allocation is set to be significantly faster—up to six times quicker—compared to previous versions. The article by Aaron Patterson highlights this improvement through various benchmarks that compare the performance of positional and keyword parameters with and without the YJIT (Yet another Just-in-Time) compiler enabled. The benchmarks measure the script's execution time as the number and type of parameters passed to the `initialize` method vary, aiming to emphasize the impact of object allocation. A graph

The author expresses their thoughts on the ongoing discussion about Property-Based Testing (PBT) versus traditional unit testing. They emphasize that PBT involves defining general properties of a function rather than specifying exact input-output pairs, which allows for testing a broader range of scenarios through random input generation. The author mentions that while PBT can handle complex cases and edge conditions better than manual testing, it requires skills in formulating properties and creating input generators. Brian's argument, as interpreted by the author, stresses that P

Nan Xiao's blog discusses recent experiences as a system software and performance engineer, focusing on debugging two multi-threading bugs. The first bug involved deadlocks occurring sporadically on certain production machines but not in the test environment. The root cause was identified after thorough investigation, revealing a copy-paste error. The second bug caused program crashes after several hours due to an unexpected assert being triggered. This was resolved by meticulously reviewing related code for potential contention issues, with a solution also emerging after consistent code examination

Johnny's Software Lab emphasizes the importance of compiler optimization for C/C++ developers. The author reflects on their early realization of compiler optimization options, specifically the GCC compiler's -O0 for debugging and -O3 for fast release code. They describe the typical process of compiling source files into object files and linking them into executables. However, the author highlights that relying solely on this process misses significant optimization opportunities in the linking phase. They explain how the compiler performs optimizations such as inlining, which

In May 2025, Quanta Magazine reported on theoretical computer scientist Ryan Williams’ groundbreaking discovery regarding the relationship between time and memory in computing. Williams initially set out to prove his mathematical proof wrong, which suggested that a small amount of memory could be as effective as a significant amount of time in computational tasks. After thorough investigation and scrutiny of his own work, he found no errors in his proof, leading him to consider the possibility that his findings were indeed valid. In February, he shared his proof

The post discusses the process of multiplying polynomials and the relationship to convolution sums. It begins with the traditional method of cross-multiplying polynomials and collecting terms, then introduces a more systematic approach using a table to visualize how coefficients correspond to specific terms in the output. The table highlights the necessary diagonals that combine to form each term's coefficient. The text then shifts to an abstract representation of polynomials as sums of coefficients multiplied by powers of x. When two polynomials, P and R
