Engineering Reliable Pagination for Public TikTok Data

TikTok's public web endpoints do not always return the page size an application requests. One route may return a small native window, another may underfill a page even though more data exists, and a cursor may represent more than a simple numeric offset. That becomes a production problem quickly: count can disagree with the number of returned records. An application can skip items by calculati...

Claude Desktop and Claude Code Are Different Windows States

On Windows, Claude Desktop, Claude Code, and provider usage are related, but they are not one state machine. A status companion needs to keep three boundaries visible. Three independent signals Application state describes whether Claude Desktop is running, minimized, hidden, closed to background, or unavailable. Claude Code session state describes whether an exact coding session is wo...

x402 Signs the Money, Not the URL. I Checked 18 Fields.

An x402 payer signature does not cover the URL. It commits to the amount, the recipient, the token contract and the chain, and to nothing that says what you are paying for. I mutated 18 leaf fields of the payment payload published in the x402 spec: 8 changes left the signature verifying, 10 broke it. I rebuilt the EIP-712 digest from that example, recovered the signer with my own secp256k1 code, ...

Stop Rescanning Every Claude Code Transcript

A transcript monitor can poll frequently without becoming expensive. The problem is not the timer by itself; it is treating the entire archive as the hot path on every tick. When a developer has months of Claude Code history, reopening every transcript and parsing a tail from every file makes steady-state work proportional to archive size. It also creates correctness risks: a tail can begin in th...

"Portfolio site" to talk about projects in my career in more detail than a resume?

I'm considering building a personal website, but instead of a traditional portfolio with polished screenshots and projects, I'm thinking about making it more like an engineering journal. I have 10YOE, and at this point, I've forgotten more than I know. Moreover, its hard for me to say "I've done a lot, trust me bro" when selling my experience to recruiters/clients/etc. and an elevator pi...

Your Agent's Confidence Score Is Not a Probability

Ask an agent how sure it is and it will happily tell you. "Confidence: 0.92." It looks like a probability. It renders nicely in a dashboard. Teams wire it into routing logic: high confidence, auto-approve; low confidence, send to a human. It feels rigorous. It is not rigorous. A self-reported confidence score is the agent grading its own homework, and it is one of the most seductive false signals...

My agent filled in every field on the form. It could not attach the three images.

I had an AI agent filling out a listing form on a web service. Every text field went in. It clicked Save Draft. All that was left was attaching three PNGs. That part never worked. I assumed that if it could fill the form, it could attach the files. Those turned out to be two different capabilities, gated in two different places, and the gate behaves differently depending on how you're running Cl...

How to Deploy a VPS

This is a tutorial about how to set up a VPS on Linode. By the end, you should be able to "spin up" a server that is ready to serve your applications to the world! When things go wrong, don't forget to take a step back and think about what you're doing (beyond just copying and pasting commands). See if there are things you can do to verify the previous steps you have taken worked and read the doc...

My eval said a perfect MCP server was broken. It was the eval that was lying.

Originally published at tengli.dev When I added an LLM-powered eval to mcpgrade, the first real run produced a result that looked like a scoop: context7 — a server with a perfect static score — failed tool selection 62% of the time. A model shown its two-tool catalog picked the "wrong" tool on 5 of 8 tasks. If I had shipped that number, it would have been wrong. Not slightly wrong — systematical...

Traceroute devlog #1

　　Didn't write a single line of code today. Spent the whole day buried in the PRD and TRD instead, and by the end of it I realized this was somehow the most exhausting day so far anyway. 　　The pitch is simple enough: connect same-colored dots with clicks on a grid. One sentence. But the second I tried to break that sentence into an actual buildable spec, I hit a wall almost immediately. First thi...

I Built a Security Tool That Proves Its Own Exploits — Then Got a Better Threat Model in the Comments

Automated offense has one embarrassing failure mode: it lies to you about winning. Point a tool at a target, and the naive success check is a substring match — see uid=0(root) in the response, call it a shell. But a service banner can print that. A tarpit can stream it on connect. And the moment your success signal is wrong, everything downstream inherits the lie: the report, the "which hosts are...

Learning to Learn: The Biggest Lesson I've Gained at Zone01 Kisumu

Learning to Learn: The Biggest Lesson I've Gained at Zone01 Kisumu When most people think about learning software engineering, they picture classrooms, lectures, and hours of note-taking. That wasn't my experience. My journey at Zone01 Kisumu has been different. Instead of being told exactly what to do, I've been challenged to find answers, solve problems, and learn through building. ...

Dang! Its been a whole year. Doesn't even feel like it. About a year ago I was employed at Techinnover Analytics Ltd, where I had several firsts - but I refuse to mention them here.
