Show HN: A 3-Tool ETL Pipeline for CSV/TSV/Excel/Parquet in Go
I built a small trilogy of Go tools:
- fileprep — preprocessing & validation using struct tags (trim, replace, normalize, etc.)
- fileframe — a lightweight, immutable DataFrame for filtering, mapping, grouping
- filesql — run SQL directly on CSV/TSV/LTSV/Excel/Parquet (SQLite under the hood)
Use them together as a tiny ETL pipeline: read → preprocess → transform → SQL query.

Show HN: I made a nice Anki-app for iOS
Hi HN,
I recently got the AnkiMobile app for iOS for Mandarin. It was buggy and feature-lacking in my opinion, so I made a nice looking Anki-compatible alternative app, with more features.
It uses a tuned FSRS5 algorithm and supports image occlusion out of the box. You can import your existing Anki decks into it or create a new one. Pretty quick to add cards with the image feature.
I'm using it right now and will add more to it so let me know what you think.
FYI, it has a one-off purchase of $14.99 to unlock it for lifetime (no taksies backsies) after a test period of seven days.

Show HN: I got tired of switching AI tools, so I built an IDE with 11 of them
Each AI has strengths - Claude reasons well, Gemini handles long context, Codex integrates with GitHub. But switching between them means losing context.
Built HiveTechs: one workspace where Claude Code, Gemini CLI, Codex, DROID, and 7 others run in integrated terminals with shared memory.
Also added consensus validation - 3 AIs analyze independently, 4th synthesizes.
Real IDE with Monaco editor, Git, PTY terminals. Not a wrapper.

Ask HN: Has ChatGPT-5.1 Regressed?
I’ve noticed that the quality of ChatGPT-5.1 occasionally drops substantially. I’m talking GPT-3 level hallucinations - wildly making stuff up or randomly inserting words in a language I do not speak.
In my repeat evaluations on the same datasets the scores are all over the place, sometimes scoring really high and sometimes doing very badly.
Has anyone experienced something similar?
I’m guessing this may be because “GPT-5.1” can sometimes choose to use a much smaller model, but for production use this makes it unreliable.
