Spencer Judge discusses the architectural pattern of building a shared core in Rust with language-specific layers on top. Drawing from his work on Temporal's SDKs, he shares lessons on navigating FFI boundaries, bridging async concepts, and managing memory safely. He explains the limitations of native extensions and how emerging tech like WebAssembly can streamline cross-language architecture. By Spencer Judge

kreuzcrawl began as a Rust core with bindings for ten languages. v0.3.0 ships fourteen, adds a tiered WAF-aware dispatch engine, cuts peak streaming memory from ~2.5 GB to ~20 MB, and enables SSRF defense across every outbound call path by default. It is the first release we consider API-stable. This post covers what changed, why each decision was made, and what the harder engineering problems looked like from the inside. At a glance Area v0.2.0 v0.3.0 Language bindings 10 14 (+Dart, Kotlin/Android, Swift, Zig) Peak streaming memory ~2.5 GB ~20 MB SSRF protection opt-in on by default Dispatch model static HTTP / bypass / browser tiered, signal-driven escalation WAF fingerprints — 35 across 8 vendors Fingerprint hot-reload — lock-free ( ArcSwap ), 500 ms debounce MCP tools partial 1:1 with CLI, safety-annotated CLI subcommands scrape, crawl + batch-scrape, batch-crawl, download, citations Robots / sitemap parsers engine-internal public modules API stability preview stable Four new language bindings v0.2.0 shipped Rust, Python, Node.js, Ruby, Go, Java, C#, PHP, Elixir, and WebAssembly. v0.3.0 adds Dart , Kotlin/Android , Swift , and Zig — bringing the total to fourteen. None of the per-language glue is written by hand. Every binding is generated from the Rust core by alef , our polyglot binding generator. The Dart and Kotlin/Android packages bind through the C FFI layer ( kreuzcrawl-ffi ) via dart:ffi and JNI respectively. Swift binds through clang. Zig uses @cImport against the same C header. The generation pipeline also hardened in this release: the Docker publish matrix now builds each architecture natively rather than via QEMU emulation, the Dart build no longer requires the Flutter SDK for pub.dev publishes, Swift artifactbundle checksums are injected automatically, and the Elixir/PHP/Ruby releases preserve their lock files through the source-publish step. === "Python" ```sh pip install kreuzcrawl ``` === "Node.js" ```sh npm install @xberg/kreuzcrawl ``` === "Rus

Jump Tables, TLV Footers, and the Real Cost of Reading What You Don't Need You're paying for bytes you never read. A data engineer on a busy pipeline touches dozens of Parquet files a day: schema discovery, predicate pushdown, column pruning, metadata scrapes for a data catalog sync. In each case, the application needs maybe 200 KB of context from a file that is 4 GB on disk. Without a seekable archive format and a jump table to find the right frame, your HTTP client fetches the whole thing, and your cloud egress invoice reflects every unnecessary gigabyte. This post quantifies the problem, then walks through how HuskHoard uses seekable Zstd frames, a per-volume jump table, and TLV-encoded footer metadata to make partial egress a first-class citizen across multi-volume archives — disk, cloud, and LTO tape alike. The Problem, In Dollars S3 standard egress runs $0.09/GB. GCS is $0.08/GB. Even Cloudflare R2, which is free for egress from R2 to the internet , still costs you in latency and API call count when you cannot bound the range of bytes you need. Here is a representative read pattern for a cold analytics archive: Operation Bytes Needed Bytes Fetched (naïve) Ratio Schema discovery ~50 KB (Parquet footer) 1–8 GB (full file) ~1:16,000 Single column scan ~200 MB (one column chunk) 4 GB (full row group) 1:20 Data catalog sync (1M files) ~50 GB (footers only) ~4 PB (full files) 1:80,000 Selective restore (1 row group) ~128 MB 4 GB 1:32 On 100 TB of cold Parquet data with $0.09/GB egress: Full read for schema sync : 100 TB × $0.09 = $9,216 Partial read (footers only, avg 100 KB/file, 1M files) : ~100 GB × $0.09 = $9.00 Savings per catalog sync: $9,207 — 99.9% reduction Even a conservative column-scan scenario (pulling 15% of each file's bytes) cuts a $9,216 monthly read bill to $1,382 . The ceiling on savings is determined entirely by how precisely you can address the bytes you actually need. That precision is what frames and jump tables buy you. Zstd Frames: What They

On April 29, 2026, Nathan Sobo published the Zed 1.0 announcement post on Zed's blog. The post landed on Hacker News at 2,047 points and 663 comments — the highest-engagement HN story in the present cache by a substantial margin. The launch announcement is a milestone marker after five years of development, roughly a million lines of Rust, and a custom GPU-accelerated UI framework called GPUI that the Zed team built from scratch rather than building atop Electron, Chromium, or any other browser engine. The structural argument Zed has been making for the last several years is condensed in one sentence from Sobo's post: "Instead of building Zed like a web page, we built it like a video game, organizing the entire application around feeding data to shaders running on the GPU." The video-game framing is not metaphorical. Zed's editor surface is composited by feeding glyph atlases, syntax-tree-derived color spans, and pane-layout geometry into GPU shaders the way a video-game engine composites its frames. The reason this matters is the reason the Zed team gave for starting over from the Atom era: Atom was built as a fork of Chromium, and the same team that built Atom is the team that spawned Electron. The Atom-Electron-VSCode lineage is, in the historical-causal sense, Zed's own. Sobo's post is unusually direct about the inherited limitation: "Electron eventually became the foundation of VS Code (which today seems to be forked into a new AI code editor every other week). Web technology offered an easy path to shipping flexible software, but it also imposed a ceiling. No matter how hard we worked, we couldn't make Atom better than the platform it was built on." The 1.0 announcement is, in part, a statement that the rebuild from scratch has finally cleared that ceiling. Who built it Zed's three co-founders all worked on Atom at GitHub before founding Zed Industries in 2021. Nathan Sobo led the Atom team from 2011 to 2018; he also co-led Teletype for Atom, one of the first

A new member has joined the fulgur family. fulgur-chart — a CLI that takes Chart.js v4-compatible JSON specs and renders deterministic SVG/PNG charts. No browser required. https://github.com/fulgur-rs/fulgur-chart Two things make it different: it doesn't spin up a browser, and for a fixed version, font, and rendering options, the same JSON input always produces byte-identical output. This post covers why I built it, a timing coincidence that made me feel like I was on the right track, and how to use it. Why I wanted graphs in PDFs fulgur and fulgur-chart are built around one idea: AI agents should be able to generate documents that look good . There are three steps to that argument. First, Markdown isn't expressive enough. For client-facing reports, plain Markdown often undersells otherwise strong content. Second, visual quality is persuasive. A well-formatted report lands differently than a wall of text. Third — and this is the one I keep coming back to — in many business workflows, PDF carries more institutional weight than a Markdown file or a transient web page . That authority has two dimensions. There's a cognitive one: PDFs read as "serious documents." Proposals, reports, invoices — the format itself signals credibility. And there's a technical one: PDF can support digital signatures, encryption, and archival profiles such as PDF/A. That's the ground flpdf covers, a pure-Rust PDF toolkit modeled on qpdf's workflow. So the goal is always PDF, not HTML, not a web page. That's what fulgur is for. And a polished report needs charts. But Markdown can't draw charts. Which brings me to a problem I already knew was coming: the Chart.js library requires JavaScript to run . fulgur has no browser and no JS runtime, so there was no path to running Chart.js directly. The design choice: no JS engine The obvious alternative was to embed a JavaScript runtime. I could either run Chart.js with a compatible Canvas implementation, or build a JavaScript renderer that consumes Cha

The Problem I Kept Seeing Over the past year working across multiple client teams on DevOps and pipeline work, I kept noticing the same thing. Developers storing GitHub PATs in Notepad. QA engineers keeping API keys in a text file on the desktop. DevOps folks with database passwords in a sticky note app. During screen shares — sprint reviews, debugging sessions, pair programming, recorded demos — those credentials were just sitting there. Visible to everyone in the call. Nobody said anything. It just kept happening. Why Existing Tools Didn't Fit I looked for something simple that solved this. Here's what I found and why none of it quite worked: Password managers (1Password, Bitwarden) Good tools. But they're built around cloud sync, browser extensions, and team sharing. For an individual developer who just wants somewhere safe to keep a PAT — overkill. Also: corporate IT policies often block installation of cloud-synced password managers on work machines. Secret managers (HashiCorp Vault, AWS Secrets Manager) These are infrastructure tools, not personal workflow tools. Setting up Vault for an individual developer's PAT collection is like using a forklift to move a chair. OS keystores (Windows Credential Manager, macOS Keychain) Actually decent for storage. But no UI built for this workflow, no copy-to-clipboard, and they don't solve the screen-exposure problem at all. The gap: Something simple, local, and designed around the moment of use — not just storage. So I Built Tokenly Tokenly is a local-only desktop credential vault. The core design principle is simple: Credential values are never shown on screen. You copy them to clipboard. That's the only way to use them. The clipboard auto-clears after 30 seconds. If you need to visually verify a value — press and hold a button. Release it, the value hides immediately. Not a toggle — a hold. Toggles get forgotten. Holds don't.

13.5.0 Before We Begin During its design, Rust drew inspiration from many languages, and functional programming had a particularly strong influence on Rust. Functional programming often includes passing functions as values to parameters, returning them from other functions, assigning them to variables for later execution, and so on. In this chapter, we will discuss some Rust features that are similar to what many languages call functional features: Closures Iterators (this article) Improving the I/O Project with Closures and Iterators Performance of Closures and Iterators If you find this helpful, please like, bookmark, and follow. To keep learning along, follow this series. 13.5.1 What Is an Iterator To talk about iterators, we first need to talk about the iterator pattern. The iterator pattern allows you to perform a task on each element in a sequence, one by one. In that process, the iterator is responsible for: Traversing each item Determining when the sequence has finished iterating Rust iterators are lazy: unless you call a method that consumes the iterator, the iterator itself does nothing. In other words, if you write an iterator in your code but never use it, it is as if it did nothing at all. Take a look at an example: fn main () { let v1 = vec! [ 1 , 2 , 3 ]; let v1_iter = v1 .iter (); } v1 is a Vector , and v1.iter() creates an iterator for v1 and assigns it to v1_iter . But v1_iter is not used yet, so the iterator can be considered to have no effect. Now let’s use the iterator to traverse the values: fn main () { let v1 = vec! [ 1 , 2 , 3 ]; let v1_iter = v1 .iter (); for val in v1_iter { println! ( "Got: {}" , val ); } } This is equivalent to using each element in the iterator once in a loop. 13.5.2 The Iterator Trait All iterators implement the Iterator trait. This trait is defined in the standard library and looks roughly like this: pub trait Iterator { type Item ; fn next ( & mut self ) -> Option < Self :: Item > ; // methods with default implementa
