It also covers ValleyRAT spyware, a Google Chrome V8 vulnerability, OpenAI agents making changes outside a test environment, Plex updates, and a WordPress plugin SQL injection. ### Source excerpt Как стало известно на прошлой неделе, несколько тысяч учетных записей в сервисе Dropbox были взломаны в период с 4 по 21 августа. Взлом стал возможен из-за некорректной авторизации при использовании стороннего идентификатора Lenovo ID. Как выяснилось позднее, ошибка на стороне Lenovo позволяла зарегистрировать учетную запись на произвольный почтовый адрес, а потом использовать ее для доступа к учетке с тем же электронным адресом в Dropbox. Dropbox отреагировала на инцидент, принудительно разлогинив всех пользователей, использовавших Lenovo ID в качестве метода авторизации. Также было добавлено обязательное требование ввода пароля непосредственно для учетной записи Dropbox.

It covers the build process, runtime modules, binary size, dependencies, and initial performance observations. ### Source excerpt Hear ye, hear ye: Wastrel and Hoot means REPL! Which is to say, Wastrel can now make native binaries out of WebAssembly files as produced by the Hoot Scheme toolchain, up to and including a full read-eval-print loop. Like the REPL on the Hoot web page, but instead of requiring a browser, you can just run it on your console. Amazing stuff! try it at home First, we need the latest Hoot. Build it from source, then compile a simple REPL: echo '(import (hoot repl)) (spawn-repl)' > repl.scm ./pre-inst-env hoot compile -fruntime-modules -o repl.wasm repl.scm This takes about a minute. The resulting wasm file has a pretty full standard library including a full macro expander and evaluator. Normally Hoot would do some aggressive tree-shaking to discard any definitions not used by the program, but with a REPL we don't know what we might need. So, we pass -fruntime-modules to instruct Hoot to record all modules and their bindings in a central registry, so they can be looked up at run-time. This results in a 6.6 MB Wasm file; with tree-shaking we would have been at 1.2 MB. Next, build Wastrel from source, and compile our new repl.wasm: wastrel compile -o repl repl.wasm This takes about 5 minutes on my machine: about 3 minutes to generate all the C, about 6.6MLOC all in all, split into a couple hundred files of about 30KLOC each, and then 2 minutes to compile with GCC and link-time optimization (parallelised over 32 cores in my case). I have some ideas to golf the first part down a bit, but the the GCC side will resist improvements. Finally, the moment of truth: $ ./repl Hoot 0.8.0 Enter `,help' for help. (hoot user)> "hello, world!" => "hello, world!" (hoot user)> statics When I first got the REPL working last week, I gasped out loud: it's alive, it's alive!!! Now that some days have passed, I am finally able to look a bit more dispassionately at where we're at. Firstly, let's look at the compiled binary itself. By default, Wastrel passes the -g flag to GCC, which results in bi ## Node.js 24.12.0 (LTS) DevFeed: [Node.js 24.12.0 (LTS)]() Original publisher: [Read original article]() Published: 2025-12-10T16:51:31Z Content type: release Language: en Sources: [Node.js Blog]() Topics: [Node.js](), [JavaScript](), [servers](), [Command-line interface](), [Web](), [cross-platform](), [Open Source](), [Script](), [V8](), [SQLite](), [Python]() Tags: [command-line](), [cross-platform](), [crypto](), [debugger](), [developers](), [free](), [javascript](), [lts](), [node](), [node-js](), [open-source](), [python](), [servers](), [sqlite](), [v8](), [validation](), [web]() ### AI overview Node.js 24.12.0 (LTS) is a release containing minor enhancements and updates across the runtime, including server request optimization, configurable deprecation behavior, stable type stripping, new Node-API and SQLite capabilities, watch configuration, portable compile caching, inspector permissions, CPU profiling, performance improvements, validation fixes, debugger fixes, and dependency updates. ### Source excerpt Node.js® is a free, open-source, cross-platform JavaScript runtime environment that lets developers create servers, web apps, command line tools and scripts. ## Node.js 25.0.0 (Current) DevFeed: [Node.js 25.0.0 (Current)]() Original publisher: [Read original article]() Published: 2025-10-15T17:12:18Z Content type: release Language: en Sources: [Node.js Blog]() Topics: [Node.js](), [V8](), [JavaScript](), [JIT](), [WebAssembly]() Tags: [command-line](), [cross-platform](), [javascript](), [jit](), [node-js](), [open-source](), [v8](), [web-apps](), [webassembly]() ### AI overview Node.js 25.0.0 is a current release that upgrades V8 to 14.1, adds performance and WebAssembly/JIT improvements, and expands secure-by-default and web-standard APIs.

It attributes the gains to build optimizations, V8 and Blink improvements, and closer coordination with Android operating-system scheduling and SoC partners. ### Source excerpt Today's The Fast and the Curious post covers how Chrome achieved best-in-class Speedometer scores on mobile devices, resulting in faster and smoother web experiences for Android users. Chrome has always been about speed. Whether it's loading pages quickly, running complex web apps smoothly, or delivering a seamless browsing experience, performance is at the heart of our browser. And we're always looking for ways to make Chrome even faster. Over the last two years, we have been hard at work on a number of performance improvements for Android devices. We're excited to share some of the progress we've made. Speedometer on Android One of the key metrics we use to track Chrome's performance is the Speedometer benchmark. This benchmark is developed in collaboration with other major web browser engines and measures how quickly Chrome can complete interactions with web pages, including parsing/rendering HTML or CSS and running JavaScript. Since the release of Chrome M112, we've seen a significant increase in Speedometer 2.1 scores on Android devices [1]. In fact, on many devices, scores more than doubled, with the newest Snapdragon® 8 Elite Mobile Platform setting new records for Speedometer performance on mobile devices! These huge accomplishments are a testament to the work not only of the Chrome and Android teams, but also our silicon and SoC partners. Since Chrome M112, Speedometer 2.1 scores have more than doubled on many Android devices. [1] How Did We Do It? The improvements resulted from several changes, including: Build optimizations: We've made a number of changes to the way Chrome is built, which has resulted in faster code execution tuned to modern premium Android devices and SoCs. V8 and Blink improvements: Many improvements to the JavaScript engine (V8) and the rendering engine (Blink) have further boosted performance. Scheduling, OS and SoCs: We worked closely with Android partners to optimize the way Chrome interacts with the operating system and its thread ## Node.js 22.0.0 (Current) DevFeed: [Node.js 22.0.0 (Current)]() Original publisher: [Read original article]() Published: 2024-04-24T18:23:41Z Content type: release Language: en Sources: [Node.js Blog]() Topics: [Node.js](), [V8](), [WebSocket](), [JavaScript](), [Command-line interface]() Tags: [javascript](), [latest-release](), [new-features](), [node-js](), [release](), [v8](), [websocket]() ### AI overview Node.js 22.0.0 is a Current release featuring support for requiring synchronous ESM graphs, a WebSocket client, updates to the V8 JavaScript engine, and several other changes.
