Gemini Diffusion

Published: 2025-05-22 | Origin: Hacker News

At the recent Google I/O event, Google introduced Gemini Diffusion, their first large language model (LLM) that utilizes diffusion techniques instead of traditional transformers. Unlike autoregressive models that generate text one token at a time, diffusion models create outputs by incrementally refining noise, which allows for quicker iterations and corrections. This enhances speed and performance, making Gemini Diffusion particularly effective for tasks like editing. One user reported it could generate an interactive HTML and JavaScript page at 857 tokens per second,

Fast Allocations in Ruby 3.5

Published: 2025-05-21 | Origin: /r/ruby

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

Why Property Testing Finds Bugs Unit Testing Does Not

Published: 2025-05-21 | Origin: /r/programming

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

Erlang/OTP 28 has been released, introducing several new features, improvements, and some incompatibilities. Key highlights include: - A source Software Bill of Materials (SBOM) added to the GitHub Releases page for feedback. - Support for priority message reception in processes, based on EEP 76. - Enhanced comprehensions with "zip generators" that allow parallel execution of multiple generators. Strict generators will now raise exceptions for non-matching patterns. - The ability to use any base

Reading code is still the most effective method to debug multi-thread bug

Published: 2025-05-21 | Origin: /r/programming

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

Link Time Optimizations: New Way to Do Compiler Optimizations

Published: 2025-05-21 | Origin: /r/programming

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

Convolutions, Polynomials and Flipped Kernels

Published: 2025-05-21 | Origin: Hacker News

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
