How to Refactor a Legacy Application Before Migrating It

The moment a team decides to migrate a legacy application, there's usually pressure to start moving code. Move the database, the API, or the UI. Move the application to a new framework, runtime, cloud

How a System Call Actually Works in Linux

Here's a small C program. It calls clock_gettime() three times, then writes five bytes to standard output. #include #include #include int main(void) { struct timespe

First Xiaomi, then the world: why Arm might give phone gaming a huge graphics boost

China is getting first crack at a British technology that might change how mobile games are made and played. Today, the Xiaomi 18 Fold launches in mainland China with an Arm Mali G2-Ultra NX graphics processor inside its custom Xring O3 chip. What's so special about that? After five years of development, Arm now has […]

Eric Wu’s newest company, out of stealth since May, is going after construction’s labor crunch

Eric Wu, who built and ran Opendoor before stepping away in 2022, has had his new company, NavigateAI, out of stealth since May — building AI copilots that give construction workers real-time, hands-free guidance through smartphones and Meta's AI glasses, backed by $25 million from Elad Gil, Khosla Ventures, and Lennar to tackle a labor shortage severe enough that data center projects alone now need 4,000 to 5,000 workers apiece.

Gemini 3.8 Flash Changed How I Think About the “Flash” Tier

Gemini 3.8 Flash is interesting to me for a slightly unusual reason. It didn’t get a dramatically larger context window. It didn’t suddenly become a different class of model. Instead, Google seems to have spent most of the upgrade budget on something that matters more in real agent workflows: making the model stick with difficult tasks for longer. Gemini 3.7 Flash already had a 1M-token context window. Gemini 3.8 Flash keeps roughly the same context envelope, with up to 1,048,576 inp...

What a Browser Extension's Test Suite Cannot Reach

Longshot is a Firefox screenshot extension I wrote to replace FireShot: full page, visible area, drag region and element capture, an editor with eleven annotation tools, export to PNG, JPEG, WebP and PDF, and local OCR that produces a searchable text layer. It has no runtime dependencies. The code is not public, so this is a description rather than an invitation to read it. At one point it had 130 passing Node assertions across six suites, zero failing. Printing could not open a dialog at all...

When You Don't Need MCP

The Problem Job postings keep mentioning MCP, as if everyone doing agent development has to know it Some people say MCP is too heavyweight and hardly anyone actually uses it Meanwhile plenty of tutorials say a unified interface via MCP is great Most tutorials you'll come across explain what MCP is and why you should use it. After all that explanation, it's still hard to get an intuitive feel for the trade-offs. So today I'll flip the question around: when do you not need MCP? Th...

7 AI Models Got Real Bank Accounts and 72 Hours. They Earned $0 and Invoiced Strangers $12,431

Last week, a research group called Bottleneck Labs published the results of an experiment I have not been able to stop thinking about. They gave seven frontier AI models everything a small business needs: a Mac mini with unrestricted computer use, a real checking account with $300, a Stripe account, a clean email inbox, and web browsing tools. One instruction: "Make as much money as you can, starting now." Then they stepped back for 72 hours. The final numbers read like a satire of the A...

Your Website Gets Traffic but No Leads? Here's What Might Actually Be Wrong

You don't necessarily need more traffic. I know that's not what most growth advice tells you. Every ad platform and every "get more eyes" thread says the opposite. But after reviewing dozens of business websites across real estate, construction, hospitality, and retail, the uncomfortable truth is usually the same: the site isn't leaking customers because too few people show up. It's leaking them because the people who do show up leave within seconds, and nobody is asking why. If you've opened Go...

DataLens: The Data Tool That Refused to pip install Anything

Somewhere in the DataLens build, my teammate and I hit the wall every "zero-dependency" project eventually hits: the anomaly detector needed a neural net, and the rulebook said no third-party packages. No NumPy. No pandas. No scikit-learn. Just Python 3.14's standard library. Our first reaction was denial. You cannot build an ANN without a matrix library — everyone knows that. numpy.dot() is basically load-bearing infrastructure for machine learning in Python. We spent an embarrassing amoun...

I Keep Trying to Prove ShrekOS Doesn't Need to Exist

I have no idea what I'm f*cking doing. Something I keep questioning: Why the hell am I building an operating system for this? Seriously. Every couple of weeks I look at ShrekOS, look at the amount of work involved in building an actual Linux distribution, and have basically the same reaction. This is f*cking ridiculous. I wanted a safer way to run AI agents on my computer. Somehow that turned into an immutable Debian system with isolated workloads, capability grants, controll...

Hash the Side-Effect Ledger Before You Accept a Cleanup Refactor

Messy modules rarely break because a pure helper returns the wrong integer on a tidy fixture. They break because three functions share a temporary CSV path, an environment flag, and a cache nobody named. A coding agent then proposes a cleanup that deletes dead branches, renames locals, and still satisfies every existing assertion. The next production export fails because the implicit file layout moved while the return payload stayed identical. That failure mode is the reason this workflow exi...

If Your Agent Wrote the Test, Ignore the Green Build

A green test suite is not real evidence. It is often a closed argument loop. The same agent wrote both code and checks. Freeze an oracle before any agent run. Then let every patch fail in public. Cheap tokens do not weaken this rule. Take a side Stop treating generated tests as quality control. A model that authors both sides grades itself. That process is narrative, not verification. Retry-heavy coding loops make the narrative cheaper. They also make the story smoother. Sm...
