Ask HN: What landmarks/lighthouses in the era of LLM/AI?

I used to have things that I knew would improve my life as a Software Engineer: books, videos, learning algorithms, practicing data structures, attending meetings. Now all those things seem archaic and nonsense. You can prompt everything in seconds. What to look at now to be actual as a professional? How to be relevant in the next cycle? How to survive this storm? What options we have? Comments URL: https://news.ycombinator.com/item?id=49920340 Points: 2 # Comments: 2

How to Build MCP Gateway from Scratch

How to Build MCP Gateway from Scratch This guide covers how to build MCP gateway from scratch - a production middleware layer that routes, authenticates, rate-limits, and observably forwards AI agent tool calls. Covers TypeScript code, architecture decisions, and hardening for multi-tenant deployments. An MCP gateway is a middleware layer that sits between AI agents and the external tools, data sources, and services they need. It handles routing, authentication, rate limiting, protocol tr...

10 Claude Code CLI Mistakes That Kill Your Productivity โ€” And How to Fix Each One

10 Claude Code CLI Mistakes That Kill Your Productivity โ€” And How to Fix Each One Most developers who pick up Claude Code make the same mistakes in the first week. Not because they're careless โ€” because the tool looks forgiving. It writes code confidently. It follows instructions promptly. It feels like it has your back. But it doesn't. Not unless you set it up to. The problem isn't that Claude Code does things wrong. It's that it does things exactly the way you asked โ€” including the...

A per-order margin ledger: reconciling what you quoted against what the carrier billed

Shipping cost in most ecommerce backends is an estimate that nobody checks. At checkout you show a number from a rate table. The parcel ships. The carrier sends an invoice six weeks later with a different number on it. Nobody joins the two, because joining them means matching a carrier's line-item PDF against your order ids, and so the difference just disappears into cost of goods sold and the margin dashboard keeps lying. The fix is unglamorous and it pays for itself: a ledger that record...

Retrying a label API that already charged you

Most retry advice assumes the operation you are retrying is free. For a shipping label API that assumption is wrong in an expensive way: the call creates a real object, it bills you when it succeeds, and the failure mode you actually hit is a timeout after the carrier already did the work. Your client sees an error. The carrier has a label, a tracking number and a charge. Retry naively and now you have two of each, one of which will never be scanned, and at some point in the quarter that turn...

Mixdog: an open-source workspace for multiple AI coding models

I built Mixdog , an open-source AI coding harness that brings models from multiple subscriptions and API providers into one workspace. I simplified the setup with a short tutorial so you can connect a provider and start working without assembling the interface yourself. One workspace, several models Mixdog supports providers including OpenAI, Anthropic, Google and xAI. You can choose different models for different agent roles and keep multiple tasks visible in split panel...

Xiaomi AI training, live: what the MiMo 2.6 RL dashboard shows

Xiaomi's AI lab is training its next model in public. The page at mimo.xiaomi.com/rl shows two reinforcement-learning runs for MiMo 2.6 "read directly from the trainer's logs": pass rates, data mix, restarts with the operators' reasons, and a cost counter that passed one million dollars on Thursday. If you have only ever seen a model through its launch blog, this is the part the launch blog leaves out. TL;DR Xiaomi is streaming two RL post-training runs: MiMo 2.6 P...

Before you give a Polymarket bot your private key: a 15-minute checklist

In 2026, "Polymarket copy-trading bot" became one of the most effective lures on GitHub. The pattern repeated all year. In February, an attacker took over a legitimate organisation's GitHub account and published more than twenty malicious repositories, several of them Polymarket copy-trading bots. Following their setup instructions installed a hidden npm dependency that read the private key from .env , sent it to the attacker's server and opened an SSH backdoor ( StepSecurity's write-up ). I...

Hearing every Polymarket trade three ways: the detection layer of a copy-trading bot in Rust

A copy-trading bot has one job that matters more than any other: notice that the wallet you follow just traded. Everything after that, from sizing and slippage control to execution and settlement, works on a signal the detection layer either delivered or didn't. On 31 August 2026 Polymarket's activity/trades websocket topic went down platform-wide, for every IP at once, for hours. Every bot that listened only to that topic went deaf. Mine had a slow REST poll as a backup, and that was all...

"Push, PR, merge." Two minutes later: "Stop. I'm not opening a PR to myself."

On September 9 at 07:21 I typed four words to an agent: push, PR, merge. At 07:23 I interrupted it: stop, just push to master, I'm not going to open a pull request to myself. The agent pushed three commits, fast-forward, and wrote the rule down so the next session would know it. In between, it had done exactly what the tooling around it is built to do, and that's the part worth looking at. The change The work was small. An internal tool keeps a catalog of entries that we generate...

From Windows to Fedora, Cursor to Zed, Opera to Zen โ€” how my stack got quieter and more intentional

I didnโ€™t wake up one day and decide to โ€œbecome a Linux person.โ€ I just got tired of a workflow that felt loud โ€” notifications, bloat, apps I didnโ€™t choose so much as inherit โ€” and curious enough to try something else. What started as a switch from Windows โ†’ Fedora (KDE Plasma) turned into a much bigger rethink: editor, browser, phone apps, even how I feel about software day to day. This isnโ€™t a โ€œWindows is deadโ€ post. Windows works for a lot of people. This is just what changed for me ,...

How to Prevent LLM Hallucinations with Guardrails (2026)

How to Prevent LLM Hallucinations with Guardrails (2026) A support bot tells a customer that worn shoes qualify for a full refund. The policy says the opposite. The answer reads fluently, cites the right document, and is wrong in exactly the detail that costs money. This hypothetical example illustrates one form of an LLM hallucination: not wild invention, but a small confident misread of a real source. Prompting the model to "be careful" does not fix it. A verification loop can catch some f...

Ask HN: If AI took your job tomorrow, what is your plan?

I'm looking for some optimism here after reading one of the recent daily threads that devolves into doom. I'm 26, single, at a non-FAANG making okay money doing software, but I can feel the AI grip tightening. Maybe it's an illusion, not sure, but it sure feels real. Does anyone here have a creative plan for other industries to get into? Ways to reduce expenses? Trying to find something people with brains like ours can look forward to.
