SPONSOR - CI Is Dead. Long Live CI.

Fri, 16 Oct 2026 00:00:00 GMT

Everyone's talking about the bottleneck shifting... our customers just want something stable as they scale, with actually good DX, that gets out of the way.
Buildkite is the pro-tool for CI orchestration, and when you're setup, you can forget we exist.
Programmable primitives you control. No compromises. Good enough for Cursor, OpenAI, Anthropic, Perplexity, Nvidia, Uber, Airbnb and more.
Build and test faster, more securely, more reliably, with the CI engineered for frontier scale, used by the teams setting the pace.
You deserve better CI.

Put A Name On It

Fri, 16 Oct 2026 00:00:00 GMT

— James Stanier

tl;dr: “As the industry has changed, our organisations have flattened. Leadership is closer to the details, and someone has to own the outcome, talk to stakeholders, and get the work done without management needing to be part of every decision. The simplest answer I know is named ownership: one person per project, by name, visible to everyone. We’ve been leaning into that for the past year, and I’d like to explore why I think it’s a very good idea.”

Management In The Age Of AI

Fri, 16 Oct 2026 00:00:00 GMT

tl;dr: “Management is becoming more important as AI changes how businesses work, and the job itself is shifting faster than most managers have noticed. Let’s talk about what’s changing and how to deal with it.”

The Art Of Showing Up

Fri, 16 Oct 2026 00:00:00 GMT

— Steve Huynh

tl;dr: “The biggest enemy of presence is our obsession with the finish line. We fixate on the feeling of relief we’ll have when the task is over. This makes the present feel like an obstacle, and it creates in us a desperate urge to escape.”

The Brain Sandwich

Fri, 16 Oct 2026 00:00:00 GMT

— Matheus Lima

tl;dr: “The reason I decided to post about this is that Emily has a very simple framework that she uses for working with AI, which she calls the “Brain Sandwich”, that solves this. It’s both about taking full advantage of AI without letting your engineering skills atrophy.”

Get More From Your Team’s AI Investment

Fri, 16 Oct 2026 00:00:00 GMT

tl;dr: Give your teams clear priorities for improving AI results. Span evaluates coding agent sessions for 1) prompt clarity, 2) environment readiness, and 3) quality stewardship, then connects those scores to delivery, cost, and rework. See where teams need support, spread effective practices, and show your CEO progress backed by evidence. Engineering leaders at Ramp and Duolingo trust Span to measure and optimize their AI software factory.

How To Be More Ambitious: A Tutorial For Humans With Models

Fri, 16 Oct 2026 00:00:00 GMT

— Felix Rieseberg

tl;dr: “I frequently proclaim (together with other people working on AI) that we ought to be more ambitious when using it. It’s become a rallying cry. Whenever we see something impressive, we repost and write “we’re not ambitious enough”. I understand how tricky it is to follow that advice, so here’s a tutorial on being more ambitious. I think of ambition in four types: Speed, Altitude, Depth, and Range.”

Are Harnesses Worth The Cost?

Fri, 16 Oct 2026 00:00:00 GMT

— Naresh Jain

tl;dr: “I went into this experiment expecting a behavioral harness to help a coding agent meet the requirements more reliably, save tokens and prevent wasted work. Giving an agent clear architectural contracts and deterministic test feedback while it coded seemed like an obvious way to help it get the implementation right on the first pass. The results flatly contradicted that expectation and surprised me.”

Beyond Synthetic Testing: Capturing And Replaying Real Database Workloads

Fri, 16 Oct 2026 00:00:00 GMT

— Zuofei Wang, Erluo Li

tl;dr: “At Airbnb, MySQL-compatible databases are a critical backbone of our online database infrastructure: a fleet of hundreds of clusters supporting thousands of use cases at millions of queries per second (QPS). Operating databases at scale brings hard problems, including sizing clusters for future growth, keeping behavior consistent across version upgrades and migrations, and reproducing production incidents well enough to debug them. This post describes the database traffic capture and replay system we built to help us tackle them.”

SPONSOR - The Context Layer For Agentic Software Development

Tue, 13 Oct 2026 00:00:00 GMT

Your agents know the code. Give them the rest of your organizational context.
Unblocked reasons across your code, conversations, issues, docs, and production systems so agents can complete work correctly with less human intervention.

Why Your Engineering Team Is Slow

Tue, 13 Oct 2026 00:00:00 GMT

— Alex Piechowski

tl;dr: “After years of codebase audits, the same five signals keep showing up, so I finally put them into a scoring rubric: The Codebase Drag Audit. Five signals, scored 0 to 2. If you hit 4 or above, the code needs direct investment before anything else will help.”

“You Didn’t Do It Right”

Tue, 13 Oct 2026 00:00:00 GMT

— Jason Cohen

tl;dr: “Four sincere attempts at OKRs, four failures, and every time: “you didn’t do it right.” Maybe the framework doesn’t fit you — so how do you find one that does?”

[Webinar] How To Stop Rewriting Your Agent’s Code

Tue, 13 Oct 2026 00:00:00 GMT

— Brandon Waselnuk

tl;dr: You write the rules files, maintain the skills, and paste in the Slack thread your agent missed. But hand-curated context goes stale, and when the sources disagree, your agent can’t tell which is right. Join us live on Oct 28 (FREE) to see how a context engine helps agents get it right the first time.

I Don't Want The Details

Tue, 13 Oct 2026 00:00:00 GMT

— Michael Heap

tl;dr: "At first I thought ""I don't want the details"" sounded dismissive. How can they make informed decisions without understanding the details? Then I realised that ""I don't want the details"" wasn't being dismissive. The executive assumed that we were competent, and was saying ""I already believe you. Now let's talk about what happens next”.

Don't Diagnose Your Opponents

Tue, 13 Oct 2026 00:00:00 GMT

— Sean Goedecke

tl;dr: “When you disagree with someone, there are two paths forward. The first is to try to engage with what they’re saying: what their reasons are, whether their position is true, what evidence could be brought to bear, and so on. The second is to diagnose them: to engage with the second-order question of why they’re saying it.”

How Do You Evaluate A Senior Engineer In The Age Of AI?

Tue, 13 Oct 2026 00:00:00 GMT

tl;dr: When AI can accelerate execution, traditional signals of seniority don’t tell the whole story. This 30-point checklist gives engineering leaders a practical framework to score senior-level readiness. It includes a ready-to-use interview questionnaire, so you can see if your hiring criteria have kept up.

How To Effectively Debug When You No Longer Understand The Code

Tue, 13 Oct 2026 00:00:00 GMT

— Cindy Sridharan

tl;dr: “I consider this an emergent skillset that’s different from coding or traditional debugging, but like any other skill, it’s one that can be honed with enough effort. While I’m no leading expert in this area, the general contours of how these skills can be actively cultivated are beginning to stand out in sharp relief. By putting my own experiences in writing, I’m hoping to hear from fellow practitioners their thoughts on this topic.”

38 Things We've Learned About Building AI Products

Tue, 13 Oct 2026 00:00:00 GMT

— Ian Vanagas

tl;dr: “We’ve built 10 different AI products at PostHog, including PostHog AI, our install Wizard, Replay Vision, Scouts, and more. They’re used by nearly 100,000 people every month. This is what we’ve learned.”

Grieving The Loss Of Details

Tue, 13 Oct 2026 00:00:00 GMT

— Alisa Sireneva

tl;dr: “I’ve been thinking about where I stand in respect to the current state of the industry. This is more of a journal note than a post, apologies for that. I usually leave this stuff private, but I thought I’d post this as a trial in case someone relates to this experience and feels less alone.”
