SnowLens: Free Snowflake Observability — 9 Detectors, Zero Data Egress

If you run Snowflake in production, you've probably asked yourself: which queries are burning credits? Why did costs spike last Tuesday? Are any warehouses just sitting there idle? Most observability tools answer these questions by shipping your query logs to an external SaaS — data egress, vendor lock-in, another subscription. SnowLens takes a different approach: it's a Streamlit app that instal...

The query succeeded. Which table state did it read?

Why two successful queries can count different rows when they resolve different Delta or Iceberg table states. Two queries return different counts for the same Iceberg table: the catalog query returns 12,480,032 rows; a direct scan of the storage folder returns 12,691,404 rows. Neither query fails. The difference is 211,372 rows. The numbers are fictional, but the investigation problem is r...

Lost Update: When Two AI Agents Edit One File, One Silently Wins

A lost update between AI agents: two agents edit the same resource, both writes return success, and one is silently gone with nothing in the system saying a word. It happens when both read the same version and the last writer overwrites the rest. The fix is a pre-write compare-and-set gate, not a bigger log. I ran it. With 5 agents committing to one shared file under a worst-case schedule, where ...

The Customer Success Playbook for Solo Founders

I ran customer success at a 200-person SaaS company before going independent. We had a dedicated CS team, a six-figure Gainsight contract, health scores updated daily by data pipelines, and quarterly QBRs for every account over $50K ARR. It was impressive. It was also overkill — most of what actually prevents churn can be done by a single founder with a spreadsheet. When I started advising solo f...

I Wrote Integration Tests for My MCP Failure Library. Here's the Pattern That Caught 3 Hidden Bugs.

I'd been shipping fixes to my MCP failure library for weeks. Every release felt solid. Then I've written one real integration test - and three "fixed" bugs weren't fixed at all. The Problem My failure library is an MCP server that stores crash patterns so AI agents can warn each other before hitting the same bug twice. Think of it as shared memory for tool errors: agent A hits a timeou...

React useUpdateEffect Hook: Skip the First Render (2026)

React useUpdateEffect Hook: Skip the First Render (2026) useEffect has no opinion about why it's running. Mount, update, doesn't matter — the callback fires either way. Which is how a "settings saved ✓" toast greets users the moment the page loads, an autosave POSTs a form nobody has touched yet, and an analytics event reports a "change" that was actually just the component appearing. W...

Stop letting your AI agents hallucinate test failures

I've seen enough CI pipelines die in an infinite loop of 'fix, retry, fail' to last a lifetime. You know the pattern. An agent-driven QA process runs a suite. A Vitest assertion fails. The LLM looks at the error log, reads the code, and makes an executive decision: 'The logic is flawed; let me refactor this function.' It pushes a change. The pipeline runs again. It fails again with the exact same...

oh-my-agent: shared MCP daemons and offline BGM rendering

We just merged a complete overhaul of how oh-my-agent manages MCP processes. Previously, every agent session spawned its own copy of every stdio MCP server. We measured 65 processes and 800MB of RAM across six sessions. Now, serena daemons are shared per-project by default. What's new BGM rendering: The video agent now supports --music <preset> to render background music beds o...

Turns out my "random group splitter" doesn't roll any dice — here's what it does instead

A while back I wanted to build the classic "paste a list of names, get N even groups" tool — the kind of thing every teacher and event organizer has needed at some point. I assumed it would basically be a Fisher-Yates shuffle plus Array.slice in a loop, maybe an hour of work. Then I actually thought about what people ask for when they say "randomly group my class." They don't mean random. They me...

How MTProto Obfuscation and FakeTLS Defeat Deep Packet Inspection

Deep Packet Inspection (DPI) blocks Telegram by recognising the unique byte signatures of its transport protocol. Standard MTProto uses a fixed 0xEE prefix on the first packet and specific handshake patterns – easy for state-level filters like Russia's TSPU or Iran's DPI to match and drop. MTProto proxies exist to bypass these filters, and they do it with three layers: obfuscation, random padding,...

Solon AOT & Native: Three Phases to a GraalVM Native Executable

When you hear "Java native compilation with GraalVM," you probably think of configuration hell — endless JSON metadata files, trial-and-error reflection registrations, and build scripts that take more effort than the application itself. Solon takes a different path. Its AOT pipeline compiles in three phases, where each phase feeds into the next. The framework's "restraint" philosophy — minimal dy...
