Wrong AdMob App ID Caused Limited Ad Serving on Live Android Game

A developer discovered that AdMob was serving limited ads on their live Android game, Logo Quiz: Guess Brand, because the ad units were registered under a different AdMob app entry than the one linked to the Play Store listing. AdMob requires a one-to-one link between a Play Store listing and an AdMob app, and since the verified app had no ad units while the app with ad units was unverified, neither could serve ads properly. The fix involved creating ad units under the Play-linked app and updating four IDs across the project, including in both app.json and AndroidManifest.xml, where the app ID is stored in two separate places. The developer noted that changing only app.json still results in the old ID being baked into the APK, and recommends inspecting the compiled artifact directly to confirm which ID was actually shipped. The key lesson offered is to create and link the AdMob app to the Play Store listing before adding any ad unit IDs to the codebase.

How to Find the Real Cause Behind Unity's 'Gradle Build Failed' Error

Unity developers building Android APKs often get stuck on the 'CommandInvokationFailure: Gradle build failed' console message, which appears hundreds of lines after the actual root cause in the log file. The true error — such as duplicate classes on the classpath — is logged around line 923, while the misleading Gradle failure message appears near line 1158. Developers can bypass the noise by running a grep command against Unity's Editor log to jump directly to the 'What went wrong' section. Common triggers include duplicate JARs in the project, such as copying unity-classes.jar under a second name, or conflicts introduced via the External Dependency Manager. Clearing resolved libraries through Assets → External Dependency Manager → Android Resolver can resolve duplicate-class errors, particularly in Unity 2022.2 and later.

Proxima Fusion to build €140M factory for fusion-grade superconducting tape

German fusion startup Proxima Fusion announced on Wednesday plans to construct a €140 million ($162.6 million) manufacturing facility. The factory will produce high-temperature superconducting (HTS) tape, a critical material used in its fusion reactor design. The move aims to secure a domestic supply of a component currently dominated by Asian manufacturers. By producing HTS tape in-house, Proxima Fusion seeks to reduce its dependence on foreign suppliers for this essential fusion ingredient.

Dev Writer Tests Every Terminal Claim on His Machine Before Publishing

A developer and technical writer behind the weekly newsletter Shellcraft has shared his core editorial rule: every terminal-related claim is verified on his own machine before publication. He estimates that roughly one in five drafted claims turns out to be incorrect upon testing, not due to typos but plausible-sounding errors rooted in outdated or misremembered information. To enforce this standard, he creates a private verification guide for each issue, outlining steps to reproduce commands and their expected outputs. He recently caught a critical error while testing a tool's panel workflow, discovering that a central step in a drafted issue did not work as described, prompting a full rewrite. Introducing himself to the DEV Community, he framed this practice as a promise to the developer audience he plans to write for there at least once a month.

Solo Dev Builds Ad-Free HTML5 Gaming Platform With 17,000 Games and 500K Players

A solo developer built Spielcade, a free browser-based gaming platform designed to eliminate the ads, malware warnings, and forced downloads common on casual gaming sites. The platform hosts over 17,000 HTML5 games across more than 25 genres and has attracted over 500,000 active players with a 4.9 out of 5 rating. It was built using Next.js, React, Node.js, and PostgreSQL, with Cloudflare CDN used to ensure fast global load times. Key technical challenges included scaling database queries for complex tag filtering, optimizing thousands of game thumbnails via lazy loading, and managing technical SEO across more than 17,000 individual game pages. The developer used server-side rendering and automated dynamic sitemaps to help search engines index the growing library effectively.

Guide: Deploy Gemma 4 2B on Cloud Run with NVIDIA L4 GPU Using Python MCP Tools

A step-by-step deployment guide has been published for running Google's Gemma 4 2B model on Google Cloud Run using an NVIDIA L4 GPU and vLLM as the inference server. The project includes a single-file Python MCP server that handles model weight staging, service deployment, health checks, benchmarking, and teardown. Cloud Run's serverless architecture eliminates the need to provision VMs or install GPU drivers manually, with the service scaling to zero when idle. The guide also covers a required migration to MCP Python SDK 2.x after a version-unbound pip install broke the server's import on fresh setups. Prerequisites include Python 3.10 or newer, Claude Code, the Google Cloud SDK with active credentials, and a GCS bucket for storing model weights.

Google Maps Full Fruit Fly Brain With 166,000 Neurons in Landmark Connectome

Google Research, in collaboration with HHMI Janelia Research Campus and other partners, has published the most detailed brain wiring map to date, charting roughly 166,000 neurons and 125 million synapses across the adult male fruit fly's brain and central nervous system. The findings were published alongside work by Januszewski, Jain, and collaborators in the journal Cell. The connectome is intended as a scientific resource to help researchers study how neural circuits process sensory information and drive behavior, not as a commercial AI product. Separately, an independent experimental project called DOOMFLY has used connectome data in a pipeline that translates simulated fly-brain activity into controls for the game Doom, though the project is self-described as exploratory and non-validated. The core achievement remains the connectome itself, which researchers hope will also inform future neuromorphic hardware design and advance mapping techniques for more complex species.

LeBron James leads Patrick Mahomes in net worth despite NFL star's rising wealth

As of 2026, LeBron James holds a significantly higher net worth than Kansas City Chiefs quarterback Patrick Mahomes, outpacing the NFL star in overall career earnings. While Mahomes has been steadily building his wealth through lucrative contracts and endorsement deals, he has not yet reached James' financial level. Both athletes have demonstrated strong business acumen, investing in sports franchises and technology ventures. James' decades-long career in the NBA, combined with his diverse investment portfolio, has helped him accumulate wealth that remains well ahead of his NFL counterpart.

California to Ban Addictive Social Media Features for Users Under 16

California Governor Gavin Newsom is set to sign a landmark online child safety bill targeting social media platforms. The legislation will prohibit these platforms from offering addictive features to users under the age of 16. It marks the first law of its kind to be enacted anywhere in the United States. The move reflects growing concern among lawmakers about the harmful effects of social media design on young users.

COSMIC Epoch 1.8 adds tablet grab, Bluetooth renaming, and XWayland fix

System76 released COSMIC Epoch 1.8 on September 10, 2026, just two weeks after version 1.7, for its Rust-based desktop environment used in Pop!_OS and other Linux distributions. According to Phoronix, the update introduces three user-facing features: improved graphics tablet input capture in COSMIC Shell, the ability to rename connected Bluetooth devices in COSMIC Settings, and support for XWayland windows launching in a minimized state via the COSMIC Compositor. However, System76's own GitHub release page lists the changelog as 'pending' and describes the update only as translation and dependency updates across the codebase. The discrepancy likely reflects incomplete release notes rather than conflicting information, as the 'pending' label suggests documentation is still being finalized. Developers building applets, packaging software, or relying on XWayland window states on COSMIC are advised to test their tools against the new release.

UP Woman and Newborn Die After Delivery at Illegally Operating Sealed Hospital

A woman and her newborn died following a delivery at a private hospital in Uttar Pradesh that had previously been sealed by authorities. The hospital was reportedly circumventing its closure order by operating through an alternate entrance despite a lock on the main entrance. The deaths came to light and prompted officials to re-seal the facility. Authorities confirmed the hospital had been operating illegally in violation of the original sealing order.
