Introducing TIN for PostgreSQL 🤟
PlanetScale just introduced a new type of the full text search index, which they claim to be blazingly fast. While the traditional engines like Lucene use the artificial document ids; doing a native full text search to Postgres allows to use ctid - physical tuple id, which claimed to significantly improve performance. Not without problems though: follow the article for the details.

| 2 | Why has Shopify dropped React Native? 🍼
Not sure you’re aware, but I used to build native Android apps, React-native apps and later Flutter apps for 10 years combined. And the discussion on the prevailing technology never were cold or absent. Looks like agentic development not only changes the way we work day to day, but also the way we evaluate technology. Shopify was the biggest promoter of React Native for the last 5 years. The era is over though.

| 4 | Uber Eats Search Pipeline 👷♂️
Search Performance is always - and I mean it - always is a holistic problem. The engineers need to search through UX approaches, caching, retrieval mechanics, query performance and of course how the full stack operates as a whole. Uber Eats shows how they touch upon every aspect, including running an AI agent with the live data profiler to fix the issues in search.

| 5 | Github 5 Incidents in August 👷♂️
The Github availability became a living joke this year, but not because of the engineering capability, but because of sheer amount of pull requests the ai agents now generate. Github shares their 5 August incidents, the reasons behind them and what they learned from them. First hand experience from the biggest code storage in the world!

| 6 | Local models will not win 🍼
I tried to see if local models are viable for serious development. Spoiler: they are not. Sean Goedecke agrees: everybody tends to choose the most powerful model in their price range, and only datacenters have the corresponding capacity. Plus, they are well optimized for it. So local models will just not happen, forget it.

| 7 | DNS Cache Memory Optimization 👷♂️
Whoever tells you data structures don’t matter in the age of AI - ban them. Cloudflare manages to save hundreds of terabytes of memory across the glove doing small optimizations to the ways DNS cache records are stored with the knowledge of how Rust store data and dropping dns owners when they are identical. Brilliant engineering work.

| 8 | Efficient Software Factory at Uber 👷♂️
While everyone talks about making software factories, Uber actually does it. They dropped a banger of an article explaining the 4 levels of AI adoption in the company, cost structure, measurement approach and of course the results. Great job!

| 10 | MicroVMs for throw-away jobs
MicroVMs is a way to provide you a short-lived isolated execution environment. What are they best for? Right, security related tasks! How about running the virus scanning on docker images?
While I am personally skeptical on mere signature-check scans in general and ClamAV in particular, the idea of running high risk payloads in isolated envs is really appealling. Checkout how to leverage MicroVMs for it.

| 11 | AWS EC2 Application Status Check 👷♂️
After decades of custom monitoring solutions, AWS introduced the every minute status check with HTTP probes. Auto Scaling groups can replace unhealthy instances based on this application status. Try it out and tell me in the comments how it improved your life!

| 13 | Should You Split Into Microservices? 👷♂️
We recently merged all our microservices(we had a handful) in a monolith. If you consider moving in a back direction, you need to ask yourself at least 5 questions on dependencies, different NFRs for the system parts, teams blocking each other, data boundaries and independent failures.
Two candidate services, each owning its database, with red cross-boundary queries between them: one service, cut in half

| 14 | Running a self-hosted LLM in Kubernetes with vLLM 👨💼
With the rise of cost for the LLMs and the privacy concerns more and more enterprises opt to run local models(and I am experimenting with them myself). Grab a guy how to setup an open-source LLM with Kubernetes!

| 16 | We became so faster writing code, but do we ship more?
Talking with Baruch Sadogursky
about what exactly prevents us from unlocking true productivity, and it's not better agents. 👇

| 17 |  Clustering Billions of Products for Agentic Commerce with Catalog API 🤓
Shopify Catalog groups billions of listings without a common schema. It first matches products inside each store, then connects them across stores with a Universal Product Identifier (UPI). LLMs assign a structured label to every product. This enables consistent grouping, high precision, and better recall. AI searches based on Catalog data convert twice as often as searches based on scraped data.

| 18 | The State of Streaming to Apache Iceberg in July 2026: Every Path, Its Latency, and What to Do When Seconds Are Not Fast Enough 👨💼
In mid-2026, teams no longer ask, “Should we use Iceberg?” They ask, “How current can our Iceberg tables be?”. And this is where the main tradeoff relies dictating your data architecture and tools to go with. From tuned Flink to Kafka connect latency numbers varies from 30 seconds to 15 minutes. How to choose? Well, Alex Merced explains in his piece.

| 19 | Most “AI agents” are workflows with an LLM inside.
The real difference: who controls the flow?
In my new video, I break down the five parts of a real agent—prompt, tools, state, memory and loop—plus the production essentials: tracing, guardrails and evals. Here's the link:
