The open-source React calendar inspired by macOS Calendar – DayFlow
https://www.reddit.com/r/programming/comments/1qn1gmz/the_opensource_react_calendar_inspired_by_macos/

<!-- SC_OFF -->Hi everyone 👋 I’d like to share DayFlow, an open-source full-calendar component for the web that I’ve been building over the past year. I’m a heavy macOS Calendar user, and when I was looking for a clean, modern calendar UI on GitHub (especially one that works well with Tailwind / shadcn-ui), I couldn’t find something that fully matched my needs. So I decided to build one myself. What DayFlow focuses on: Clean, modern calendar UI inspired by macOS Calendar Built with React, designed for modern web apps Easy to integrate with shadcn-ui and other Tailwind UI libraries Modular architecture (views, events, panels are customizable) Actively working on i18n support The project is fully open source, and I’d really appreciate: Feedback on the API & architecture Feature suggestions Bug reports Or PRs if you’re interested in contributing GitHub: ** (https://github.com/dayflow-js/calendar)https://github.com/dayflow-js/calendar\*\* (https://github.com/dayflow-js/calendar%5C*%5C*) Demo: ** (https://dayflow-js.github.io/calendar/)https://dayflow-js.github.io/calendar/\*\* (https://dayflow-js.github.io/calendar/%5C*%5C*) Thanks for reading, and I’d love to hear your thoughts 🙏 <!-- SC_ON --> submitted by /u/Cultural_Mission_482 (https://www.reddit.com/user/Cultural_Mission_482)

Locale-dependent case conversion bugs persist (Kotlin as a real-world example)
https://www.reddit.com/r/programming/comments/1qndjes/localedependent_case_conversion_bugs_persist/

<!-- SC_OFF -->Case-insensitive logic can fail in surprising ways when string case conversion depends on the ambient locale. Many programs assume that operations like ToLower() or ToUpper() are locale-neutral, but in reality their behavior can vary by system settings. This can lead to subtle bugs, often involving the well-known “Turkish I” casing rules, where identifiers, keys, or comparisons stop working correctly outside en-US environments. The Kotlin compiler incident linked here is a concrete, real-world example of this broader class of locale-dependent case conversion bugs. <!-- SC_ON --> submitted by /u/BoloFan05 (https://www.reddit.com/user/BoloFan05)

[Meta] Mods, when will you get on top of the constant AI slop posts?
https://www.reddit.com/r/programming/comments/1qni22q/meta_mods_when_will_you_get_on_top_of_the/

<!-- SC_OFF -->They never do well in terms of Karma or engagement. All they do is take a spot in the feed better suited to actual meaningful content. They constantly break rules 2, 3, and 6. At a bare minimum that should be enough reason to remove them. But more than that, AI has as much to do with programming as it does visual artistry. Which is to say, for those that care, nothing at all. LLMs and their enthusiasts have other spaces to share their posts. It's clear by common consensus that /r/programming (https://www.reddit.com/r/programming) does not want to be one of them. At this point I'm just padding things out for word count. So, for the sake of facetiousness, here's Gemeni pointlessly reinterpreting what have already said above, since that's apparently the level of content were comfortable with around here. ---- Option 1: Direct and Policy-Focused This version stays professional and emphasizes the subreddit’s standards. AI-related posts consistently see low engagement and poor karma, yet they continue to clutter the feed and displace higher-quality content. More importantly, these posts frequently violate Rules 2, 3, and 6, which alone warrants their removal. Just as in the art world, many in the developer community view AI as a separate entity from the craft itself. Since there are dedicated spaces for LLM discussion, and the consensus here is clearly negative, we should keep /r/programming (https://www.reddit.com/r/programming) focused on actual programming. Option 2: Community-Centric (The "Purist" Perspective) This version leans into the sentiment that AI isn't "real" programming work. It’s time to acknowledge that AI content doesn't belong here. These posts rarely spark meaningful discussion and often feel like noise in a feed meant for genuine development topics. Beyond the technicality that they often break sub rules (specifically 2, 3, and 6), there’s a deeper issue: to a programmer, an LLM is a tool, not the craft. If the community wanted this content, it wouldn't be consistently downvoted. Let’s leave the AI hype to the AI subreddits and keep this space for code. Option 3: Short and Punchy Best for a quick comment or a TL;DR. AI posts are a poor fit for /r/programming (https://www.reddit.com/r/programming). They consistently fail to gain traction, violate multiple community rules (2, 3, and 6), and don't align with the interests of those who value the actual craft of programming. There are better subreddits for LLM enthusiasts; let’s keep this feed dedicated to meaningful, relevant content. <!-- SC_ON --> submitted by /u/Omnipresent_Walrus (https://www.reddit.com/user/Omnipresent_Walrus)
