Rate Limiting Isn't One Layer: What LogicVisor and Titan Actually Do Differently

"Add rate limiting" sounds like one task. It's actually three separate layers, each defending against a different failure mode, with different trade-offs and different amounts of trust you can place in them. I only understood the distinction properly once I had to pick a strategy for two systems solving different problems: LogicVisor (a public AI tool anyone can hit anonymously) and Titan (a payme...

Your status enum lives in five files

You need to add one value to a status. PENDING, AWAITING_PAYMENT, ACTIVE, SUSPENDED — and now ARCHIVED. So you go looking for where statuses live. Here's what you find: constants.ts — a frozen const object, ORDER_STATUS, screaming case. types.ts — a union of string literals, written by someone else, with the same members in a different order. orderService.ts — a switch with the literals inli...

what a turn actually costs me

Four models read every frame Harness sees. CLIP embeds it. PaddleOCR pulls the text. A dense-text model embeds that. A reranker sorts results when you search. None of them bill me. They run in the tab, on your machine. That's the cost structure. That's the strategy. Screen capture and a MAD gate decide which frames survive. CLIP (clip-vit-base-patch16) for image and text embedding. PaddleOCR for...

Database Isolation Levels & Read Phenomena: An Extensive Deep Dive

Databases are messy places. In the real world, thousands of users are reading, writing, updating, and deleting data at the exact same millisecond. Because databases are multi-user systems, letting transactions run completely unchecked creates total chaos. When concurrent transactions access and modify the same data at the same time, anomalies emerge. To keep things under control, databases give u...

Running Kimi Code on Claude Code

I pay for Claude and I pay for Kimi Code, and I want both available from the same terminal without choosing one in the morning. Kimi publishes a guide for pointing Claude Code at their endpoint. It tells you to export a handful of environment variables in your shell profile, which works, and which also routes every Claude Code session on the machine to Kimi from then on. Your Anthropic subscriptio...

MCP C# SDK Protocol Negotiation: Pin 2026-07-28 When Fallback Is Unsafe

MCP C# SDK protocol negotiation can quietly change the wire contract beneath an otherwise successful connection. The stable MCP C# SDK 2.0.0 release prefers the 2026-07-28 protocol, but it also keeps older servers working through automatic fallback. That compatibility is useful. It can also hide the fact that a client expecting sessionless behavior actually negotiated an initialize-era session. ...

Your agent's failures are silent: measuring failure modes in production

Originally published on Loop & Retry — field notes on building LLM agents that survive production. The failure that hurts is the one that doesn't throw. A traditional service fails loudly: an exception, a 500, a stack trace, a red line on a dashboard. An agent fails quietly. It runs to completion, returns a confident answer, exits zero — and the answer is wrong, or it spent forty steps and \$...

I think I’m being farmed for prompts

I just became a senior dev at a Fortune 500 company in the US. My team is dysfunctional and has been since I joined. My coworkers are mostly non-native English speakers who do the bare minimum to get by (these two are not correlated, just laying out the context). I’m one of the few who works to gather requirements, understand the why behind our work, and ask questions to clarify details. I make su...

gRPC over a Unix socket, not HTTP: a real IPC tradeoff from a HIPAA-postured edge system

I'm building PhotonicOps, an offline, air-gapped telemetry ingestion and agentic hardware-triage engine for silicon photonic biosensors. That's the kind of microfluidic optical sensor used in clinical biomarker detection. It ingests resonance wavelength shift data (Δλ, picometers) at 10,000 samples/sec, cleans and analyzes it with DSP, and (in the next phase) will use a local LLM to decide on hard...

We measured the "AI review tax" across 5,388 repos. The median repo doesn't pay one.

The claim you hear from one side is that AI-written code is a review burden everywhere. The claim from the other is that it's free velocity. We read 5,388 public repositories — 444,225 merged pull requests — and both sides are wrong in an interesting way: the median repo pays no review tax at all, and a quarter pay a real one. Where the cost lands says more about the repo than about the tools — an...

What actually gets evaluated in a "product thinking" interview round for a senior engineer?

I've got a round coming up specifically framed as "product thinking," run by a product person, not an engineering manager. No coding involved, just a conversation about prioritization, tradeoffs, scoping. For anyone who's been on either side of a round like this: what separates a strong answer from a weak one? (Disclosure: used an AI assistant to help word this post. The situation and qu...

The Difference Between Good Code and Bad Code is 5 Minutes

I'm a fan of the KISS principle. Keep it simple. That applies when you're building something new, but it applies just as much when you're fixing something old. Across every role I've had — agency work, staff engineer at a fintech startup, time at AWS and Meta, consulting for startups, building my own products — the pattern is always the same. The difference between code that's maintainable and co...

Beyond the Switchover: Using RDS Snapshots to Safely Test MySQL 8.4 Compatibility Before Your Blue/Green Cutover

AWS RDS Blue/Green deployment is a powerful zero-downtime tool, but its Green environment is read-only by design. Here is how to layer a snapshot-based test instance on top of it to validate application compatibility before committing to the full switchover. There is a moment every DevOps engineer, DBA, and SRE dreads: a database engine reaches end-of-life, AWS begins billing you for Ex...

Kyverno allowLatestTag Pitfalls: How Policy Can Stop Pods From Restarting

A pod gets evicted at 3am because a node ran out of memory. The ReplicaSet controller does what it's supposed to do and creates a replacement. The replacement never gets admitted, because six weeks earlier someone applied a disallow-latest-tag policy and that Deployment still references :latest. The workload had been running fine the entire time. Now it's gone, and it isn't coming back on its own....

I got tired of SSHing into 10 VMs a day, so I built a live map of my whole infrastructure

Every day at work looked the same. Something breaks, or I need to push a new image, and I'm SSHing into three different VMs, running docker ps on one, kubectl get pods on another, piecing together in my head what's actually connected to what. The official Kubernetes dashboard never stuck for me either, and I never bothered installing Lens everywhere I needed it. At some point I just wanted one th...
