thefuck (https://github.com/nvbn/thefuck) in Rust – because life's too short for slow fucks.

500ms → 15ms startup. Same rules, 50x faster. 2x faster correction time as well.

I'm loving the momentum behind Linux, particularly Arch, right now. I've used it for years but recently have been switching all of my workflows to it. I wanted a quick way to see all my tasks at a glance without context-switching between apps. Since I already use Waybar, it felt like the natural place to make that available. There wasn't really something out there for that, and I had todos scattered amongst different local notes and Obsidian, so I built Tasuki to aggregate them together.

My startup helps companies save money on Snowflake, and over the past two years we've built out a lot of observability features based on customer requests.

We're launching these features for free for everyone. You can read more here: https://espresso.ai/post/observability

pg_stream is a PostgreSQL 18 extension that keeps materialized views current incrementally — no external infrastructure, no separate streaming pipeline.

You define a stream table (a SQL query + a freshness bound) and the extension derives a delta query that processes only changed rows on each refresh cycle:

SELECT pgstream.create_stream_table( 'regional_totals', 'SELECT region, SUM(amount) AS total, COUNT(*) AS cnt FROM orders GROUP BY region', '1m', 'DIFFERENTIAL' ); One INSERT into a million-row table → pg_stream touches one row's worth of computation. Query it like any regular table.

How it works: - Trigger-based CDC captures row changes into buffer tables inside the same transaction (no wal_level = logical required) - A background worker walks a topological DAG of stream tables and fires refreshes in dependency order - The DVM engine (differential view maintenance, DBSP framework) rewrites your SQL into a delta query at definition time — JOINs, GROUP BY, CTEs, window functions, LATERAL, subqueries all supported - Stream tables can depend on other stream tables; a change to a base table cascades automatically through the entire chain

Written in Rust using pgrx. 1,300+ tests (unit + integration + E2E). dbt macro package included.

I built GameScout AI because I never really liked the recommendations sites like Steam propose. It uses natural language to find games based on specific mechanics or moods, like "cozy farming sims with a bit of action" or "something like Dark Souls but funnier".

The Stack:

- Next.js & Tailwind: For a responsive, gaming-focused UI.

- Groq (Llama 3): I’m using Groq for inference because sub-second latency makes semantic search feel like a local DB query.

- Prompt Engineering: Optimized to explain why a game was picked based on actual mechanics, not just metadata.

Any feedback is appreciated!

In January, a Chinese app called Sile Me ("Are You Dead?") went to #1 paid app on China's Apple App Store. One button. Tap it daily to say you're alive. Miss two days — your emergency contact gets an email. It went viral because 200M Chinese people live alone and finally had a tool that acknowledged the obvious risk.

The US has 40 million solo households — 29% of all households, an all-time high. And no good equivalent.

So I built one. Key differences: SMS instead of email, a 48-hour window instead of rigid schedules, and an Emergency Alert button — one tap, immediate text to your contact. Right now, not after two days of silence.

Tech stack: Expo/React Native, Python/FastAPI, RevenueCat for IAP. iPhone only for now.
