A creator explains that a free mint on Base charges the buyer no mint price, so the buyer pays only the transaction gas, which varies with network conditions. The expected cost is estimated by multiplying the wallet's gas estimate by the current gas price, with the confirmed receipt as the final record. The author describes preloading token URIs on-chain at about 0.0000008 ETH each, versus lazy minting, which shifts that storage cost to the mint path. A contract limit of five mints per wallet applies to the deployer too, so tests should use a fresh address. The piece also stresses that pinning metadata before exposing a mint is necessary, since on-chain URIs do not guarantee the content exists.
Vasundhara S, writing for Hack with Bangalore 4.0, describes RecallOps, an AI-powered maintenance assistant built for industrial settings. The project was motivated by the observation that repair knowledge is often lost, with successful fixes poorly recorded and failed attempts forgotten, leading technicians to repeat the same troubleshooting steps. Unlike general-purpose chatbots, RecallOps draws on a store of previous repair experiences and their outcomes to inform new investigations. Users can report a failure, receive an AI-assisted analysis, review related historical cases, and log whether the repair actually resolved the problem. The tool uses Hindsight Cloud to retain and retrieve these experiences, and is intended to assist technicians rather than replace their judgment.
AI beauty applications are growing more advanced, with brands adding virtual makeup try-ons, AI skin analysis, and personalized product recommendations. Building them demands more than bolting AI onto an e-commerce site, often requiring computer vision, facial landmark detection, augmented reality, and secure data handling. The article highlights seven companies worth evaluating in 2026: Perfect Corp, Banuba, CodingCops, Revieve, PulpoAR, Ravento, and GlamAR. These firms span specialized beauty technology providers, SDK vendors, and custom AI engineering shops, so the right choice depends on whether a business needs ready-made technology, a custom app, or both. The piece also outlines typical features such as AR nail try-on, shade matching, and beauty assistants, and the criteria used to shortlist the vendors.
A developer argues that the usual indie game studio stack, which can cost $50 to $100 monthly, can be replaced entirely with free tools. The recommended set includes GDevelop, a no-code engine that exports one project to multiple platforms, and Inkscape for vector 2D art. It also features OBS Studio for recording and DaVinci Resolve for video editing, whose free tier is praised for its quality and compatible upgrade path. Finally, the author suggests using Dev.to to publish videos and gain organic traffic and backlinks without maintaining servers.
