Introduction Why am I writing this article? The reason is simple: a while ago, a new project at my company required us to integrate Google Pay and Apple Pay. The service had already completed its credit card payment flow. However, management later requested support for Google Pay and Apple Pay as
The Month GitHub Public Contributions Exploded To date, GitHub remains the most widely used code storage cloud platform. The amount of data pushed to GitHub every year is tremendous. In 2025 alone, GitGuardian's Public Monitoring platform analyzed more than 2 billion commits. This represents aroun
The build process for iOS applications involves multiple technical stages, including source code compilation, resource packaging, code signing, and IPA generation. Xcode is the first choice for most iOS developers, but build tools are not limited to Xcode alone; choosing the right tool for different
Why every JS collapsible-tab library lags by a frame on a fast fling, and what it took to fix it natively for React Native. If you have built an Instagram- or Twitter-style profile screen in React Native, you know the layout: a header that scrolls away, a tab bar that pins under it, and a swipeable
Last verified: 2026-09-05 — LiteRT 2.2.0, LiteRT-LM 0.16.1, litert-torch 0.9.4, ai-edge-litert 2.2.0. Every version and link below was read on that date. On-device tooling moves monthly; check the linked page before you pin anything. Direct answer LiteRT is TensorFlow Lite, renamed on 20
A practical UIKit screenshot pipeline, a paywall layout bug, and the failure modes to fix before trusting CI. iOS visual regression testing can start with a small, local pipeline: launch a specific screen, capture it on a simulator, and compare its pixels against an accepted baseline. The difficu
Sim-to-Real Transfer for Physical AI Robots A policy that hits 95% success in simulation and 20% on the real robot is one of the most common — and most frustrating — outcomes in robot learning. The gap between simulated and real-world dynamics, sensing, and visuals is called the sim-to-real gap, a
Domain Randomization for Robust Robot Learning Domain randomization is the idea that, instead of trying to perfectly match simulation to reality, you randomize simulation parameters widely enough that reality just looks like "one more variation" the policy has already seen. It's one of the highest
Using VR Controllers for Robot Teleoperation VR controllers (Meta Quest, HTC Vive, Valve Index, etc.) have become a popular input device for robot teleoperation, and for good reason: they provide precise 6-DOF tracking, built-in buttons/triggers for gripper control, and an intuitive mapping betwee
Building and Testing Robot Policies with MuJoCo MuJoCo has become one of the go-to physics simulators for robot learning — it's fast, accurate for contact-rich manipulation, and has first-class Python bindings via mujoco and dm_control. This tutorial walks through setting up a robot environment in
The Kotlin 2.4.20 release is out! Here are the main highlights: For the complete list of changes, see What’s new in Kotlin 2.4.20 or the release notes on GitHub. How to install Kotlin 2.4.20 The latest version of Kotlin is included in the latest versions of IntelliJ IDEA and Android Studio. To updat
Password-reset emails, referral invites, and order confirmations all end the same way: a link that should land on the right screen. In development the link works because the simulator is warm, the session is fresh, and you tap it from the same device. In production it breaks because the app was kill
Bluetooth can tell you that a device is probably nearby. Ultra-wideband can tell you that it is 42 centimeters away and 18 degrees to the right, until the person holding it turns and the direction disappears. What is Codename One? Codename One is an open-source framework for building native iOS, An
Shpper is a cross-border personal-shopping marketplace. A buyer wants something they cannot get where they live. A traveller is already flying that route with unused luggage space. The platform introduces them, holds the money until the item arrives, and turns an empty few kilos in someone's suitcas
Helm's storage tool shows your disk as a treemap: every folder a rectangle, every rectangle sized by how much space it takes. Click one and you are inside it, looking at its children, with a breadcrumb trail back out. It goes from a 494 GB volume down to a single file. I drew it by hand. Not becaus
The answers were usually fine. The first 90 seconds were not. I would leave a call knowing what I meant to say, and also knowing I had looked at the wall, rushed the punchline, or sounded unsure. Practicing in my head did nothing. A mirror does not tell you if you sped up. Friends are kind. A coach
Turning a JSON payload into a Kotlin data class looks trivial until you hit the details: which annotations, what about snake_case, what happens to missing fields? The answers differ meaningfully across the three mainstream libraries. Here's the same payload, three ways. The JSON: { "user_id":
I was building KODA Browser. Android project. WebView. Custom home screen. Search. GitHub shortcuts. It was starting to become a real browser. And then I paused it. Not because it failed. I paused it because I realized something: I've built a lot of things. But I haven't really tested whether
You have a list of a million rows and you want to jump to row 842,013. ScrollController.jumpTo takes a pixel offset, not an index. To convert one to the other you need the total height of the 842,012 rows above your target — and a lazy list has never built them, so it does not know how tall they ar
This is a submission for Weekend Challenge: Generosity Edition What I Built I built MatrixRainView, an open-source Android library that allows developers to easily add a fully customizable Matrix-style digital rain effect to their applications. The goal behind this project was simple: m
