# We Added MCP to PromptOT: Manage Production Prompts from Claude, Cursor, and Codex

Developers increasingly use Claude, Cursor and Codex to write, review and improve application code. But when those applications depend on production LLM prompts, there is usually a disconnect. Your AI coding assistant can modify the application, but it cannot safely: Find the production prompt Understand its current version Update a specific prompt section Create a draft Compare versions Add t...

Devs... Building in Public Is Dead!?

Where Does That Leave Us? Developers, Authority, and Sharing in the Age of AI In 2014, if you were an ambitious developer trying to make a name for yourself, you built in the open. You wrote code publicly, you blogged your thought process, you spoke at meetups, and you shared your ideas freely. That was the culture: openness as a path to credibility. If you wanted to be seen as someone ...

How to set Content Security Policy with a Meta Tag?

How to set Content Security Policy with a Meta Tag?

When developers start implementing a Content Security Policy (CSP), they usually configure it through HTTP response headers. But then a common question comes up: 👉 Can I define CSP using a <meta> tag instead? The answer is: Yes—but with some important limitations. While using a meta tag can be convenient during development or on static websites, it doesn't provide the same level of prot...

Refactoring OpenTelemetry Metrics: from God Class to Per-Subsystem Modules

The constraint that shapes everything A refactor that recently landed in a codebase I work in replaced our metrics god class with per-subsystem modules. The design was a colleague's work, not mine. But studying the change, and migrating my own instruments over to the new pattern, taught me more about OpenTelemetry's design constraints than any tutorial had. The constraint that shapes e...

Multi-Tenant AI Chat: From Hardcoded Config to BYOK in 4 Steps

Two tenants, two AI providers, two prompts. Sounds simple, and on day one it is. That's the trap. It stays simple right up until customer number two sends their first "quick question," and eighteen months later you're running a small distributed system to answer it. Here's the honest version of that slide, four stages, each one caused by a real human typing a real request into Slack. Day...

Idempotent notifications with an outbox: separate detection from sending, re-check before send

Send a notification the instant you detect its condition, and the short gap before delivery bites you. Stock runs out, a price reverts, a watch is removed — tens of seconds to minutes later, the alert may no longer apply. I solved this with the outbox pattern in a price watcher I built (Cloudflare Workers + D1): detection only enqueues, and a separate step re-checks right before sending. Here are...

Management blames QA for prod bugs. QA now over-flags everything. we're stuck in a loop. What do you think is the issue? How would you handle this?

Senior dev, around 9 YoE. I just wanna do some sanity-checking. I'm frustrated and want to make sure I'm not just ranting. Here's the loop I'm stuck in: Bugs reach prod. Director gets angry "why are these still getting through?" QA, scared of being blamed, starts over-flagging everything, including things that aren't actually bugs and aren't in the task's scope. My PM accepts those flag...

Building Against Real APIs Is Nothing Like Reading the Docs

A few months ago, I started spending a lot more time working with different APIs. At first, I thought authentication would be the hardest part. Once OAuth was working and I could successfully make requests, I assumed everything else would mostly be connecting the dots. It didn't take long to realize I was wrong. The real challenge wasn't getting data. It was figuring out what that data actually...

Extremely toxic boss returned only me to office 5 days per week. How much do I work from now on? 13YoE FE DEV in EU.

13YoE, FE DEV in EU. I have a teamlead-manager who's widely known across the whole company to be very toxic. For 2.5 years everything was going really well. I had always been receiving either "Meets expectations" or "Exceeds expectations". Suddenly one Sunday morning at 1:15 AM I receive a slack message with a RTO5 mandate just for me. Since then I go to the office or coffee ba...

Build a Semantic Cache for Your LLM App in 40 Lines of Python (And Cut Costs by Half)

If you're calling an LLM API for every single user request, you're almost certainly paying for the same question more than once. Not because your users are dumb because human beings ask the same thing in a dozen different ways, and a normal cache only matches exact strings. "how do I reset my password" and "reset password help pls" are, to a dict or a Redis GET, completely unrelated. To your user...

A Threat Actor Used DeepSeek to Orchestrate 460 Attacks via Telegram

A threat actor based in Zhuhai wired DeepSeek into an open-source agent framework called Hermes, then piloted the whole setup via Telegram to attack hundreds of internet-facing systems. Palo Alto Networks' Unit 42 published the analysis on August 2. Here's what matters: it's not an edge case. The attacker wove together three off-the-shelf pieces, a frontier AI model, a published agent framework, ...
