The update also introduces typed results, coordinate helpers, image bridging, and analyzer-specific native dependency selection. ### Source excerpt CodeScanner and VisionCameraView put full-screen scanning and embedded live analysis above Codename One's on-device vision APIs, with typed results and simulator scripting. ## Run for your money: Engineering a treadmill that prints store credit DevFeed: [Run for your money: Engineering a treadmill that prints store credit]() Original publisher: [Read original article]() Author: Nikola Draca Published: 2025-11-25T13:31:13Z Content type: article Language: en Sources: [Shopify Engineering](), [Shopify Engineering - Shopify Engineering]() Topics: [Shopify](), [Extension](), [Barcode](), [real-time](), [Python](), [Socket.IO](), [Hardware]() Tags: [checkout](), [code](), [customer](), [data](), [engineering](), [events](), [extensions](), [hardware](), [python](), [real-time](), [retail](), [sensor](), [shopify](), [ui]() ### AI overview Shopify and Endorphins Running built a gamified manual treadmill for the 2025 NYC marathon weekend. A pace sensor sent Bluetooth FTMS data to a Python script, while Socket.IO and a Shopify POS UI extension connected the running experience to store-credit redemption. Participants earned credit for maintaining a selected pace and received a barcode for applying their discount at checkout. ### Source excerpt We combined FTMS sensors, Socket.IO, and POS UI extensions to turn a manual treadmill into a discount-printing machine. ## Meltdown and Spectre Server Updates and Codename One Feature Updates DevFeed: [Meltdown and Spectre Server Updates and Codename One Feature Updates]() Original publisher: [Read original article]() Author: Shai Almog Published: 2018-01-16T00:00:00Z Content type: article Language: en Sources: [CodeName One]() Topics: [Vulnerabilities](), [Server](), [IO](), [Objective-C](), [Java](), [iOS](), [Barcode](), [QR Code](), [simulator](), [API]() Tags: [announcement](), [api](), [blog](), [io](), [ios](), [java](), [objective-c](), [qr-code](), [servers](), [simulator](), [updates](), [vulnerabilities]() ### AI overview The post announces server updates in response to the Meltdown and Spectre chip vulnerabilities, with possible short-term downtime and limited expected impact on build speed because IO, rather than CPU speed, is the main bottleneck. It also mentions new Codename One libraries for Objective-C interoperability and Scandit barcode and QR code scanning, plus a push notification simulator feature. ### Source excerpt I've been so busy I just don't have time to blog as much as I should. I do hope next month will be better in this regard (more on that below) but right now I have to make an important announcement. There are new chip vulnerabilities I'm sure you heard a lot about specifically Meltdown & Spectre. Thankfully we are at a layer that shouldn't be impacted by these issues but we need to update our servers and will be doing so over the course of the next few days (possibly more as patches get updated).
