That's probably the most common question I got over the last few months. As of today, I am very happy to share that the answer has changed from "It's coming soon" to "A first cut is there, give it a try" -- the first Beta of Hardwood 1.1 is out! This is a major milestone for the project, marking the first step in evolving Hardwood from being solely a Parquet parser to a complete library for this widely used columnar file format. But there's more. This release also comes with significant enhancements to the query layer (Bloom filters, dictionary-based row-group pruning), many performance improvements such as a fast path for effectively fixed-length list columns, an even snappier CLI, and much more. Let's dig into some of the new features and changes! ## Designing Android's missing WorkManager test rule DevFeed: [Designing Android's missing WorkManager test rule]() Original publisher: [Read original article]() Author: Segun Famisa Published: 2026-08-30T06:00:00Z Content type: tutorial Language: en Sources: [Segun Famisa]() Topics: [Testing](), [Library](), [Android]() Tags: [android](), [guide](), [integration-testing](), [library](), [testing]() ### AI overview The article presents a WorkManager test rule intended to reduce repeated setup, cleanup, state retrieval, and API calls when testing Android work. It discusses the androidx.work:work-testing library, integration-style testing with TestDriver, and a proposed WorkManagerTestRule. ### Source excerpt TL;DR - create a work manager rule to make your tests easier to write. It's not hard to do, and it pays off. I have been working quite a bit with WorkManager stuff these days, and while attempting to write tests for them, I realised there were things I was doing repeatedly. Work Manager provides a helpful testing library - androidx.work:work-testing and they have a very nice guide on how to write tests for work manager - both integration tests, and testing worker implementation details1, and despite this, I found myself writing a couple of things over and over again. This post is somewhere between bringing awareness to testing APIs available for WorkManager, and showcasing a test rule that I think can help lower the barrier to testing. Before Say I have a SyncDispatcher class that does sync, and sometimes, I want to keep existing work, and other times, I want to replace the existing work. class SyncDispatcher(val workManager: WorkManager) { fun sync(params: SyncParams) { val existingWorkPolicy = if (params.syncAll) { ExistingWorkPolicy.REPLACE } else { ExistingWorkPolicy.APPEND_OR_REPLACE } val workRequest = OneTimeWorkRequestBuilder() .setConstraints(Constraints.Builder().setRequiredNetworkType(NetworkType.CONNECTED).build()) .build() workManager.beginUniqueWork("sync-work", existingWorkPolicy, workRequest) .enqueue() } } If I wanted to test this behaviour in an "integration-testing" style, I could use the TestDriver API2 of work manager to instrument the constraints that my work depends on, be it initial delay, network condition, period delay (for perioidic work), stopping the work with a reason, and so on. // SyncDispatcherTest.kt @Before { val config = Configuration.Builder().setExecutor(SynchronousExecutor()).build() WorkManagerTestInitHelper.initializeTestWorkManager(testContext, config) } @Test fun `sync all drops all prior sync requests`() = runTest() { // given that we have previous sync work enqueued dispatch.sync(syncPartialParams) // when we ## Why regex isn't email validation DevFeed: [Why regex isn't email validation]() Original publisher: [Read original article]() Author: WorkOS Published: 2026-08-24T00:00:00Z Content type: article Language: en Sources: [WorkOS Blog]() Topics: [Parsing](), [Forms](), [HTML5 and CSS3 tricks](), [Library](), [Internet]() Tags: [advice](), [deliverability](), [domain](), [email](), [forms](), [framework](), [html5](), [internet](), [library](), [regex](), [validation]() ### AI overview The article explains that email syntax validation with regexes, HTML5 checks, or framework libraries does not establish deliverability or confirm that a mailbox exists. It recommends a loose syntax check and stopping there, while recognizing that stronger checks address separate, less reliable questions. ### Source excerpt Checking that an address looks right and checking that it can receive mail are different problems. Most signup forms only solve the first one. ## Ruby Instance Variables Are Not Inherited (and Why That Breaks Your DSL) DevFeed: [Ruby Instance Variables Are Not Inherited (and Why That Breaks Your DSL)]() Original publisher: [Read original article]() Author: Daniel Doubrovkine (dblock@dblock.org) Published: 2026-08-14T00:00:00Z Content type: article Language: en Sources: [Daniel Doubrovkine]() Topics: [Ruby](), [bug](), [Library](), [Development](), [Rails]() Tags: [bug](), [development](), [library](), [open-source](), [pull-requests](), [rails](), [ruby]() ### AI overview This article explains how Ruby instance variables used by the ruby-enum gem are not inherited by subclasses, causing failures involving subclassing, class reloading, and redundant module inclusion. It describes fixes shipped in ruby-enum 1.2.0, including lazy defaults and explicit merging of inherited enums. ### Source excerpt The ruby-enum gem is a small library I maintain that adds enum-like behavior to a class via include Ruby::Enum and define :KEY, value. Four pull requests landed against it recently, each fixing a different symptom, and all four turned out to be the same underlying bug: class-level instance variables set in a module's included hook are not inherited by subclasses the way you might expect. All of these fixes shipped in ruby-enum 1.2.0. Ruby::Enum stores its keys and values in instance variables on the class itself, set up when the module is included. def self.included(base) base.extend ClassMethods base.instance_variable_set(:@_enum_hash, {}) base.instance_variable_set(:@_enums_by_value, {}) end This works fine for a single class. It gets interesting the moment subclasses or class reloading show up. A user opened #56, reporting DuplicateKeyError from a Rails console after a class that had already defined its enums got reloaded. It reproduces without Rails. class_body = proc do include Ruby::Enum define :RED, 'red' end Colors = Class.new(&class_body) Colors.class_eval(&class_body) # raises DuplicateKeyError Rails' development-mode autoloader re-evaluates a class body, and the second define :RED sees @_enum_hash still holding RED from the first load, so the duplicate-key check fires. The fix clears the hash whenever Ruby::Enum is included, rather than assuming it's always a fresh class. The contributor that reported the problem and submitted the fix also caught a sneakier variant: a subclass that redundantly re-includes Ruby::Enum (include is supposed to be idempotent, right?) was wiping out enums inherited from its parent, because included unconditionally reset the instance variables: class OtherSecondSubclass < FirstSubclass include Ruby::Enum # redundant, but shouldn't lose FirstSubclass's enums define :MAGENTA, 'magenta' end Thanks, Nazar, for tracking both of these down with tests. Months later, #49 surfaced a related crash: a subclass that never calls define itsel ## Why We Wrote a New JWT Library for Kotlin Multiplatform DevFeed: [Why We Wrote a New JWT Library for Kotlin Multiplatform]() Original publisher: [Read original article]() Published: 2026-08-07T00:00:00Z Content type: article Language: en Sources: [Touchlab | Enterprise Mobile Innovation & Development]() Topics: [JSON Web Tokens](), [Kotlin Multiplatform](), [Cryptography](), [Authentication](), [Authorization](), [Open Source](), [Library]() Tags: [authentication](), [authorization](), [community](), [cryptography](), [jwt](), [kmp](), [kotlin](), [kotlin-multiplatform](), [libraries](), [library](), [open-source]() ### AI overview The author explains how a security-focused Kotlin Multiplatform banking project led to research into cryptography and JWTs. After finding that JJWT was limited for cross-platform projects, they began developing a new JWT library as a personal open-source learning project. ### Source excerpt Earlier this year, we silently started working on and published a new KMP library. The reason it exists serves as a good lesson on how to start contributing to the open-source community. ## Why "state management" is a misleading term in React DevFeed: [Why "state management" is a misleading term in React]() Original publisher: [Read original article]() Author: Alex Russell Published: 2026-07-23T00:00:00Z Content type: opinion Language: en Sources: [Alex Russell]() Topics: [React](), [JavaScript](), [GraphQL]() Tags: [alternatives](), [frameworkism](), [javascript](), [library](), [react](), [redux](), [state-management](), [webdev]() ### AI overview This opinion article argues that "state management" is an imprecise label for React and the surrounding ecosystem. It surveys libraries including Redux, Zustand, Apollo, and others, and contends that they primarily encapsulate state or propagate notifications about state changes rather than manage state themselves. ### Source excerpt It is by no means the gravest linguistic crime of the React epoch,1 but "state management" grates like nails on chalkboard. A Socratic dialogue I keep having about it goes something like this: me: This UI is far too heavyweight for what it does, have you considered not using React? them: But how will we do state management without React? me: What do you mean? are reactive. them: React manages state in our app. me: It does? Then what are for? them: Oh, those manage state. me: The libraries that trigger this "Who's on First?" routine include: MobX, which promises "simple, scalable state management." Satchel, apparently, "is characterized by exposing an observable state that makes view updates painless and efficient" Recoil, billed as "a state management library for React" Jotai, which pledges "primitive and flexible state management for React" XState, a "state management and orchestration solution for JavaScript and TypeScript apps" Apollo, promising "a comprehensive GraphQL state management library for JavaScript" Redux, tagline: "a predictable state container for JavaScript apps." TanStack Store, "a framework-agnostic state primitive for immutable updates" Zustand, described as the "🐻 bear necessities for state management in React" Contrasts sharp enough to cut softened butter.2 Suffice it to say, the ecosystem has not picked a winner. Indeed, I regularly see several of these libraries on a single page. But even one would seem too many, given that we're adding a second "state management" system to a framework that spills considerable documentation ink chest-beating about its state management facilities. One of the following must be true: React is a state management system and someone has smuggled in a duplicative dependency we can jettison. React is an inadequate state management system and we should stop trusting it with an ill-defined subset of the "state management" problem. React is not a state management system and we should s ## Useful Python Libraries Every Network Engineer Should Know DevFeed: [Useful Python Libraries Every Network Engineer Should Know]() Original publisher: [Read original article]() Author: j2sw Published: 2026-07-21T12:35:00Z Content type: tutorial Language: en Sources: [Justin Wilson (j2sw)]() Topics: [Python](), [Library](), [networking](), [Code]() Tags: [apis](), [automation](), [bgp](), [cisco](), [code](), [devops](), [firewalls](), [library](), [netops](), [network](), [network-engineering](), [network-operations](), [python](), [python-libraries]() ### AI overview This article introduces Python libraries for network engineering, explaining how they support device connections, API interactions, automation, configuration backups, audits, and reports.

It explains the motivation, configuration, publishing workflow, and supported mappings for Kotlin features such as classes, enums, data classes, coroutines, generics, interfaces, and exceptions. ### Source excerpt with kotlin-native-nuget plugin, you can bring your Kotlin to C# idiomaticallyhttps://medium.com/media/0f185efc67390bbf440bfc33f5675f42/href A little while ago, I gave a talk where I tried to take a library written in Kotlin and hand it to a .NET developer as a NuGet package. By hand. It is 30 minutes of me walking into every brick wall you can imagine - the C ABI, marshalling strings, keeping objects alive across the boundary, making any of it look like C# a human would actually want to use. Introducing kotlin-native-nuget 🪟kotlin-native-nuget plugin auto-binds your kotlin api into C# I turned all of that into a plugin, so you don't have to hit a single one of those walls. You write Kotlin, and out the other side comes a NuGet package with a proper, idiomatic C# API: classes, enums, data classes, coroutines, Flow, generics, interfaces, the works. No FFI boilerplate, no hand-written [DllImport], no "here's a C header, good luck". Your friends over in .NET just `dotnet add package` it and use it like it was C# all along. It's called kotlin-native-nuget, and it's a Gradle plugin. Here's the pitch: GitHub - xxfast/kotlin-native-nuget: A plugin that packages a Kotlin/Native library as a NuGet package with generated C# bindings, and consumes C# NuGet packages from Kotlin The pitch 🛗plugins { kotlin("multiplatform") id("io.github.xxfast.kotlin.native.nuget") version "" } kotlin { mingwX64 { binaries { sharedLib { baseName = "mycatlib" } } } macosArm64 { binaries { sharedLib { baseName = "mycatlib" } } } } nuget { publish { packageId = "MyCatLib" version = "1.0.0" authors = "yourname" description = "My Kotlin/Native library" rootPackage = "com.example.cats" } } That's it. Add the plugin, point it at your native targets, and run the publish task. Out pops a .nupkg. Why though? 🤔 It's a fair question. I got it a lot (even on that talk) Kotlin Multiplatform already reaches an absurd number of places: the JVM, Android, iOS, JS, Wasm, and native desktop.

It explains embedding the file's bytes in the executable, using simdjson to synthesize a typed C++ object, and detecting malformed JSON during compilation instead of at startup. ### Source excerpt Suppose that you have a configuration file in JSON. Something like this: { "width": 1920, "height": 1080, "fullscreen": true, "title": "My Game", "volume": 0.8 } Normally you ship this file alongside your program, open it at startup, read it, and parse it. That is a lot of work for data that never changes. What if ...
