Entry-Level Data Engineering Is Gone. Here's the Proof.

I've been on both sides of the data engineering hiring table for years. Interviewed candidates, been the candidate, watched the market shift underneath both. Here's something nobody in the industry is saying plainly: if you're trying to break into data engineering as a junior in 2026, the door you're walking toward doesn't exist anymore. That's not pessimism. That's the data. The 67% Ju...

Debugging LLM Calls: How to Trace What Your AI Agent Actually Did

So I was messing around with a little side project, a chatbot that answers questions about the World Cup. Fun, low stakes, nobody's paycheck depends on it. Someone asked it "has the tournament ended yet?" It said no. Confidently. Wrong. It had actually ended weeks earlier. Fine, models get things wrong sometimes, that's not exactly breaking news. What actually got me was the next question: why?...

2026 Fields Medal Deep Dive: What Four Mathematicians' Papers Actually Say, and Why AI Needs Math

TL;DR: On July 23, the 2026 Fields Medals were awarded. Wang Hong and Deng Yu — both Peking University alumni — became the first Chinese nationals to win in the same year. But this isn't a news article. It's a heist. Inside these four mathematicians' papers are four ways of thinking you can steal and use today. The Part That Doesn't Matter Who won, which institution, how old they ...

Importing a leased /24 into OVHcloud with BYOIP (and skipping the $612/mo IP bill)

I run IPbnb, so IPv4 economics are kind of my whole day. But this one still catches teams off guard, so let me walk through it like an engineer, not a marketer. OVHcloud bills Additional IPs at $2.39 per IP per month. Fine for a couple of addresses. Now do a /24: 256 addresses × $2.39 = ~$612 / month, forever And you own none of it. The addresses are OVH's, the reputation you build on th...

Rand Fishkin on Zero-Click Search and Why Web Discovery Is Becoming More Concentrated

Zero-click search did not begin with generative AI. That is the central argument Rand Fishkin makes in a Search Engine Land interview, where he describes a longer shift in which a smaller group of platforms increasingly controls how people find information online. For publishers, marketers, and enterprise teams, the implication is not simply that search is changing. It is that the routes through w...

5YOE - SF based - how did you land a job in this market?

My workplace hurts me and is dying itself. I had an early ai startup that I was the founding engineer of, circa gpt3.

I tried to compile TypeScript into a native binary with scriptc

TL;DR: I tried to compile the TypeScript 6 compiler into a native binary with scriptc, and I failed — it got 90% of the way there and then hit an internal compiler error it couldn't get past, so there is no native tsc at the end of this story. But it's a failure worth having: I learned exactly where a week-old TypeScript-to-native compiler runs out of road, and I got some interesting numbers alon...

Coding Doesn't Make You a Software Engineer

Many students graduate knowing how to code. Very few graduate knowing how to engineer software. That's the uncomfortable truth most Computer Science students discover only after facing their first real interview—or worse, after joining their first job. Every year, thousands of students complete coding challenges, solve hundreds of LeetCode problems, build flashy portfolio websites, and prou...

Every claim on my site carries its sources. Here is the schema that forces it.

I run a fact-check site for an unreleased game. That genre is a swamp: half the pages you find are somebody's guess reprinted six times until it reads like news. I wanted the opposite, so I made provenance a schema requirement instead of an editorial habit. If a claim has no source, the build fails. Here is how that works in Astro, and what it cost me. Sources live in the content schema...

Younger Consumers Are Leaning Toward AI Answers, but Trust Still Shapes Search

Younger consumers are showing a meaningful preference for AI-driven answers over conventional search results, according to survey findings published by Vox Media. The shift matters because direct answers can change how people discover information, assess sources, and move from a question to a decision. But the available evidence also points to a more complicated reality than a wholesale replacemen...

Modern web development has become incredibly powerful. But also increasingly complicated. Many projects begin by installing hundreds of megabytes of dependencies before writing a single page. Frameworks, bundlers, routers, templating systems, CSS tooling, and runtime libraries all solve important problems, but they also introduce additional complexity. I wanted something different.
