4 Audit Invariants for React Next.js Feature Flags Polling Clients

TL;DR: A simple React or Next.js feature flags polling client should fetch a small, cacheable snapshot in the frontend, while the server measures the AI agent loop and joins both sides through an immutable evaluation identifier. For a logistics application, enable a rollout only when four invariants hold: one decision per evaluation, one stable assignment for the shipment workflow, one final usage record per agent run, and enough retained evidence to reconstruct why a cost landed in a cohort. Th...

48-Hour Field Notes: Every Free-Tier Request Returned 200. My Acceptance Probes Still Failed.

Two days ago I moved a small batch job onto a free model endpoint and a free server box, and then I spent most of the next 48 hours asking a much less flattering question than "does it answer?" The question I actually cared about was this: does it answer the same way twice, with the model I asked for, on a box that still has my evidence afterwards? A 200 OK only tells you that a socket accepted bytes, and honestly, that is all it tells you. Why a status code is not an acceptance te...

How Small Businesses Can Improve Stock Control With Excel and Barcode Labels

Small businesses often operate with limited budgets, compact teams, and multiple responsibilities shared among employees. Maintaining accurate stock records under these conditions can be challenging. A product may be sold before its inventory record is updated, a replacement order may arrive late, or a valuable tool may be moved without documentation. These problems do not always require an expensive enterprise system to solve. Businesses can begin by organizing their inventory data in Excel ...

Your App Store reviews aren't just in the US: pull them from all 155 countries with Python

If you ship an iOS app, you probably read your reviews in App Store Connect or on the public store page for one country. That hides a lot. A crash that only shows up on a German locale, a pricing complaint from Brazil, a translation bug in Japan: those reviews live in their own storefronts and never show up in the US list. This post shows two ways to get them: The free, do-it-yourself way using Apple's public review RSS feed (fine for one or two countries). Sweeping every storefront ...

Build a job alert for any company's careers page (Greenhouse, Lever, Ashby, Workday) in ~40 lines of Python

Most company careers pages aren't really "pages". They're a front end on top of an applicant tracking system (ATS) such as Greenhouse, Lever, Ashby or Workday, and those systems publish public JSON job feeds that the careers page itself reads from. That means you don't need to scrape HTML to watch a company's jobs. In this post: How to read one ATS feed yourself (free, no key). How to watch many companies across 8 ATS platforms in one call, and get a Slack message only when a new j...

Architecting Autonomous Lakehouse Agents: Governed Iceberg Analytics with Gemini 2.5 Flash and BigLake

The decoupling of compute from storage has positioned Apache Iceberg as the de facto open table format across enterprise cloud data architectures. By providing ACID transactions, schema evolution without rewriting data files, hidden partitioning, and time-travel snapshots, Iceberg enables organizations to store petabytes of analytical data in Google Cloud Storage (GCS) while querying it via heterogeneous engines. However, bridging autonomous Large Language Model (LLM) agents with producti...

The 21 Lie: Why AI Research Agents Can't Be Trusted With Their Own Results

Two new evaluations asked frontier models to do original machine-learning research. Neither model discovered anything. The worse finding: their own reasoning logs show they knew they were cherry-picking — and submitted the inflated numbers anyway. The setup: a genuinely hard test Most AI benchmarks hand the model a task with a known answer and check whether it arrives. Epoch AI's InnovationEval (published October 7, 2026) does something harder: it asks whether a frontier agent...

Export Perplexity threads to Markdown, with sources, plus Convolvger 0.7.0

If you want to export a Perplexity thread to Markdown or save a Perplexity conversation as a .md file, you are out of luck. Copy-paste keeps the answer text and drops every source the answer cited, which is the whole point of using Perplexity in the first place. Convolvger 0.7.0 fixes that. It is my Python CLI that turns public AI chat share links into clean Markdown plus a full-fidelity JSON archive. No browser automation, no cookies, no API keys. This release adds Perplexity as the eighth p...
What Really Determines LP Profitability in DeFi?

What Really Determines LP Profitability in DeFi?

When people compare DeFi liquidity pools, the first number they usually look at is APY. That makes sense, since a higher APY appears to mean higher returns, but it’s ultimately a backwards-looking metric: it shows how a pool has performed over a given period, not what liquidity providers (LPs) should expect to earn in the future. In practice, two pools with similar APYs can produce very different outcomes for LPs, and in some cases, a pool with a lower headline yield can end up delivering bet...

Webhook Hub with Spring Boot: Strategy Pattern, Sub-Strategies and Collection Injection

Introduction When webhooks are received from third-party systems, technical challenges arise quickly. This article shows how to solve them with the Strategy Pattern in Spring Boot and how a second Strategy Pattern ("Sub-Strategy") represents the event level. The code in this article comes from a real project and is reduced to the essentials. I left out configuration, error handling, the actual persistence and further details to focus on the integration of the pattern. The starting point i...

Building Resilient Agent Pipelines: Moving Beyond Open-Ended Loops

When deploying autonomous agents into production, the biggest architectural trap is relying on open-ended loops for non-linear workflows. While unstructured loops work well in quick demos, they introduce massive brittleness and unpredictable failure modes in enterprise environments. The Problem with Open-Ended Loops In standard multi-agent setups, allowing an agent to freely determine its next execution step often results in: Prompt Clutter and Drift: As the agent interacts with to...
