Danielle Navarro discusses the challenges of computing the eigendecomposition of matrices on real-world computers, emphasizing that errors are common, as outlined in Wilkinson's analysis from 1965. She recounts a troubling experience faced by colleagues who encountered reproducibility issues while running simulations in R that involved sampling from a multivariate normal distribution. Despite using set.seed() to control the random number generator (RNG), the results varied drastically across different machines, indicating a significant failure in reproducibility. While random number generation

The content discusses a personal mathematical exploration inspired by doodling in middle school, which led to the discovery of a fractal structure affectionately named "the wallflower." The author reflects on how they initially created this design by combining and copying squares on graph paper, and later realized it relates to well-known fractals like the Gosper Curve. With newfound mathematical skills, the author investigates this structure further, describing its iterative nature and how it can tile the plane. They also mention using an L-System for

In March, a project to port the TypeScript compiler and toolset to native code was announced, achieving a 10x speed improvement for most projects through the use of Go and shared memory parallelism. The TypeScript Native Previews are now broadly available, allowing users to access a preview of the native TypeScript compiler via npm and try the new editor functionality in Visual Studio Code. The new executable, called tsgo, functions like the existing tsc tool and will eventually be renamed. Although still

The content discusses query planners, which are crucial components in databases and SQL engines that determine the most efficient execution method for a given query. The process begins with creating a logical plan from the query, which is then translated into a physical plan for execution. As organizations often store data across diverse systems, querying this scattered data can be complex. A distributed SQL engine helps by connecting to various storage systems like PostgreSQL, ClickHouse, and data lakes or analytics engines. An example illustrates querying data from two sources

The author has successfully integrated Guile with a specific Nofl-based garbage collector, highlighting its ease of use by simply updating build options. While the initial implementation has been smooth, the author is currently facing challenges related to heap sizing strategies in the Whippet system, which include fixed, growable, and adaptive (MemBalancer) approaches. The long-term goal is to implement the adaptive strategy, which allows the heap to grow and shrink according to allocation rates, but accurate tracing of heap edges is necessary

Intel's 13th and 14th generation CPUs, particularly desktop models, are suffering from a hardware issue related to degradation in the clock tree circuitry, leading to clock skew and increasing glitches in performance. This problem has been noted in gaming, specifically with Unreal Engine titles like Fortnite, where crash reports indicate that the issue affects certain CPUs disproportionately. While Intel has released microcode updates to mitigate the degradation, symptoms such as frequent crashes and decompression errors remain prevalent, even on machines with healthy RAM and

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,

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
