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

The document discusses the pre-alpha version of the Kotlin Language Server and its plugin for Visual Studio Code, which implements the Language Server Protocol (LSP) for Kotlin. It is based on the IntelliJ IDEA platform and currently supports only JVM Kotlin Gradle projects. The project is experimental, focusing on enhancing developer experience, including Java interoperability and debugging capabilities. However, it lacks stability guarantees, so it's suited for experimentation but not for critical daily use. Users are encouraged to provide feedback and can track current features

The content discusses the author's experience of submitting a research paper that was initially rejected but later accepted after making a few strategic changes. The author highlights that the majority of a paper's perceived quality is determined by its first page, which includes the title, abstract, Figure 1, and half of the introduction. They emphasize the importance of making these elements specific, memorable, and clear to hook the reader. The author notes that a dramatic increase in review scores occurred from the initial rejection (scores of

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

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

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
