mishrapravin441··on Show HN: I built an international calling platform for the past 6 months
Loved it, it's amazing. Few questions How many developers developed it? How much time it took? You started earning? How are you advertising? Why not people call from there phone for international call?
mishrapravin441··on Show HN: I built a tutor that teaches only by asking questions
haha this is cool, from where u took the knowledge base?
mishrapravin441··on Show HN: Snipscribe – a digital organizer for your pen and paper notes
Curious how you are handling snippet boundaries?
mishrapravin441··on Python 3.15’s interpreter for Windows x86-64 should hopefully be 15% faster
ust to clarify, I’m writing these comments myself. I use grammar llm plugin though to clean up phrasing, but the substance is mine.
mishrapravin441··on Show HN: A local-first, reversible PII scrubber for AI workflows
This feels broadly useful beyond translation — e.g., prompt sanitization for support agents or RAG pipelines. Have you experimented with feeding the enriched tags directly into LLM prompts (vs MT engines) and how they behave?
mishrapravin441··on Show HN: Gwt-Claude – Parallel Claude Code sessions with Git worktrees
This is a neat use of git worktrees. Isolating Claude Code per branch avoids a lot of context loss when juggling bugfixes and features. The .env copy + auto-launch touches are thoughtful.

That makes sense, thanks for the detailed clarification. Having the switch-case interpreter as a fallback and keeping the dispatch autogenerated definitely reduces the long-term risk.
mishrapravin441··on Show HN: Minimalist editor that lives in browser, stores everything in the URL
Very nice exploration of URL-as-state. The approach is elegant, but the mobile crashes highlight how hostile real-world URL handling still is once links leave the browser.

Really nice results on MSVC. The idea that tail calls effectively reset compiler heuristics and unblock inlining is pretty convincing. One thing that worries me though is the reliance on undocumented MSVC behavior — if this becomes widely shipped, CPython could end up depending on optimizer guarantees that aren’t actually stable. Curious how you’re thinking about long-term maintainability and the impact on debugging/profiling.
