About pi_22by7

Freelancer and entrepreneur building useful software (debatable).

I run blink42 Technologies (blink42.com), and in my free time, work on projects like In-Memoria (AI agent memory infra), Flowrite (songwriting app), and various data tools.

By day I work with big data systems, by night I build things I actually want to use.

Built some stuff that positively impacted for a few hundred users, got obsessed with doing things like that. Always trying to make technology less annoying.

    You do use AI! And I do too, I started my work with AI about 2 years after you did, and the experience and opinions I have match yours to a T. However, I have tried AI to do things…

    The key insight about bloom filters lacking synergy is excellent. The ~7K document crossover point makes sense because inverted indexes amortize dictionary storage across all docum…

    Hey HN, I'm the author. I got tired of re-explaining my codebase to Claude and Copilot every session. They forget everything—architecture, patterns, conventions. It's like talking …

    Show HN: In Memoria – AI memory layer for persistent context in coding tools

    A couple weeks ago I shared In Memoria, an MCP server that gives AI coding assistants persistent memory. The basic problem is that tools like Claude and Copilot forget everything b…

    Show HN: Built a memory layer that stops AI agents from forgetting everything

    Tired of AI coding tools that forget everything between sessions? Every time I open a new chat with Claude or fire up Copilot, I'm back to square one explaining my codebase structu…

    Nice work on the game! The recording shows it off well. Good thinking using asciinema for this kind of thing. I'd probably be the idiot who types pacman and wonders why it's trying…

    This looks really useful for documentation. The text-based approach seems like a huge advantage over screen recordings. Being able to copy-paste commands from a "video" is brillian…

    I’m with @NitpickLawyer on this; the scan is cool, but I was hoping for a bit more detail on what’s actually being exposed. Even something like a breakdown of common tool names or …

    Thanks for jumping in, that’s actually really helpful context. Parallelism and selective test execution built-in sounds like a huge win, especially for CI and larger teams. I’ll ad…

    True. Tests usually dominate the time budget. But from what I've experienced, slow builds still hurt, especially when you're iterating frequently or working across multiple modules…

    So it did the same work that a sitemap does? Interesting. Or maybe more like the opposite: robots.txt told bots what not to touch, while sitemaps point them to what should be index…

    Honestly, I'm getting tired of the endless parade of "better" build tools. Maven works fine for most of what I do, even if it's occasionally painful. Gradle is... well, Gradle has …

    This is a sharp dissection of ‘inevitabilism’ as a rhetorical strategy. I’ve noticed it too: the moment someone says ‘X is inevitable’, the burden of proof disappears and dissent b…

    I built this because I was tired of songwriting apps with subscriptions and ads interrupting my creative flow. It's open source, works offline, and syncs across all platforms. You …
