How We Built an Atomic Circuit Breaker to Survive Third-Party API Outages at Scale
Every modern backend relies on third-party APIs for things like payment gateways, SMS notifications, or shipping calculations. But what happens when that external API slows down or goes completely dark? If your application keeps blindly hitting an of
Building real-time features
"Real-time" covers a lot of ground - a chat app, a live dashboard, presence indicators, and collaborative cursors have very different needs. Picking the wrong transport or architecture leads to features that work in a demo and fall apart under real l
How much does it cost to build a SaaS MVP?
"How much will it cost?" is the first question every founder asks, and the honest answer is: it depends on scope, team, and how disciplined you are. But "it depends" is useless when you're planning a budget or raising a round. So here are real ranges
Stop Using Offset for Pagination: Switching to Cursor-Based Filtering for Massive Datasets
When building APIs, data tables, or infinite scroll feeds, standard pagination is usually handled via SQL offsets: SELECT * FROM activity_logs ORDER BY id DESC LIMIT 20 OFFSET 500000; While this works beautifully on small datasets, it contains a mass
Server-side rendering and SEO
Your content can be brilliant, but if a search crawler receives a blank HTML shell and a bundle of JavaScript, none of it counts. Rendering strategy - where and when your HTML gets built - quietly decides whether Google sees a finished page or an emp

Beyond 'Think Step by Step': How to Build a Reasoning Scaffold That Forces AI to Actually Think
"Think step by step" used to be a genuine insight. It isn't anymore - at least not as a complete prompting strategy. The phrase triggers a reasoning mode, yes. But it gives the model zero constraints on how to reason. The model fills in the blanks th
Apple Foundation Models [SUBSCRIBER]
Apple Foundation Models is a practical guide to building intelligent, on-device AI applications using Appleβs new Foundation Models framework. Designed for Swift developers, this book introduces the fundamentals of large language models before guidin
Anchor Pointing: a tiny convention for durable codeβdoc links, no tooling required
The problem Doc references to a line number or function name break the moment code gets refactored. You write "see line 142 of foo.py " or "see calculateRefund() " in a design doc, then six months later the line has shifted or the function got rename
AI Agent Security Happens at the Tool Call | Focused Labs
At what point does a team treating AI security as plumbing, meaning nobody wants to investigate, debug, or test it because that would slow the work down, fail? At the tool call. A dangerous question that must be answered at every tool call: who is ac
Scraping Korea's biggest stores: the hidden JSON APIs behind Olive Young, Musinsa & Naver
Korean e-commerce is one of the richest, least-scraped data sources on the web. K-beauty and K-fashion drive billions in global demand, but almost every tutorial you find scrapes Amazon or Shopify - because the Korean platforms sit behind a double wa
Apache Data Lakehouse Weekly: July 1 to July 8, 2026
The lakehouse community spent this week deciding how change itself should work. Apache Parquet opened a formal vote to adopt versioned releases for breaking changes, borrowing a governance model that Iceberg refined over years. Apache Polaris cancele
Decoding the Obfuscated Bash Script on a Uniqlo T-Shirt: A Developer's Deep Dive
Originally published on tamiz.pro . Recently, a Uniqlo UT graphic tee featuring what appeared to be a complex, obfuscated Bash script caught the attention of the developer community. More than just abstract art, this design presented a genuine puzzle
From Solo Bot to Agent Fleet: A Practical Guide
The Architecture Problem Last month, I hit a wall. My single AI agent-a scraper that monitored competitor pricing-was working fine. But then I needed it to cross-reference data, generate reports, and post updates to a Telegram channel. Suddenly, my "
How to build a SaaS MVP in 2026
A SaaS MVP is not a smaller version of your final product - it's the smallest thing that proves people will pay for the problem you're solving. Teams that internalize this ship in weeks. Teams that don't spend months polishing features nobody asked f
How to integrate AI into your product
Every product roadmap now has "add AI" on it, and most of those features will be quietly removed within a year. Not because the technology doesn't work - it works remarkably well - but because it was bolted on to look modern rather than to solve a re
Monorepo vs polyrepo
How you split your code into repositories seems like a plumbing decision, but it quietly shapes how your team collaborates, ships, and reasons about the system. A monorepo keeps everything in one repository; a polyrepo gives each service or app its o
Carnot Efficiency: The Hard Ceiling on Every Heat Engine
Picture a power plant burning fuel to spin a turbine. It is tempting to assume that with enough engineering - better seals, smoother bearings, cleaner combustion - the plant could be pushed toward converting nearly all its heat into useful work. It c
Multi-tenant SaaS architecture patterns
Multi-tenancy is the decision that quietly shapes your entire SaaS backend. Get it right and you scale smoothly to thousands of accounts. Get it wrong and you're rewriting your data layer under load, mid-growth, with customers watching. The good news

The State of Streaming to Apache Iceberg in July 2026: Every Path, Its Latency, and What to Do When Seconds Are Not Fast Enough
The most common architecture question I get in 2026 is no longer "should we use Iceberg." That one is settled. The question now is "how fresh can our Iceberg tables be," followed immediately by "and what do we do when that is not fresh enough." Those
The State of Apache Polaris in July 2026: From Incubating Catalog to the Governance Layer of the Open Lakehouse
I have a personal stake in this one, so let me declare it up front. Apache Polaris was co-created by Snowflake and Dremio, I work at Dremio, and I co-authored Apache Polaris: The Definitive Guide for O'Reilly. I have watched this project from the fir
