Testing Next.js App Router API Routes Without Leaving Your Editor

If you work with Next.js, you know this routine. Write an API route, switch to Postman or Thunder Client, rebuild the request, test it, then jump back to your code. Do this a few times a day and it starts to eat into your focus. The problem is not that these tools are bad. It is the constant context switch. Your routes live in your codebase, but your tests live somewhere else, usually behind a lo...

LinkedIn frontend switches to React.js

LinkedIn is using React.js these days, but what’s interesting is the CSS side of things too. They seem to have gone down a fairly “in-house atomic CSS” direction, somewhat similar in spirit to tools like StyleX or Linaria. It’s kind of funny looking at LinkedIn’s frontend history: Ember.js: LinkedIn was one of the biggest adopters of Ember. React.js: They’ve since moved heavily toward React. Lin...

Swift ARC Doesn’t Scan the Heap — I Removed strong_release from SIL to Prove It

Also available: Korean version · Source code and reproducible experiments A source-to-runtime experiment with Swift 6.3.1: inspect ownership in SIL, delete one strong_release, measure the resulting leak, compare weak-reference lowering, and follow the call stack into the Swift runtime. Swift ARC is sometimes explained as if it were a background service that periodically scans memory and frees ...

Daily Dose of DevOps — What is CI/CD and why it matters

CI/CD as a Control System: From Commit Entropy to Production Evidence CI/CD is often reduced to automation, but its deeper purpose is epistemic: it converts uncertain changes into evidence about whether a system remains safe to operate. A pipeline is a feedback controller. Source changes are disturbances; tests, policy checks, and telemetry are sensors; deployment strategies are actuato...

Kubernetes DNS was failing 33% of the time. CoreDNS was fine.

A WordPress site on our platform started throwing Error establishing a database connection. Not always — maybe one page load in three. Reload, and it worked. Reload again, broken. The obvious suspect is MySQL. It wasn't MySQL. It took us longer than it should have to stop looking there, so here is the whole path, including the two wrong turns. The first wrong turn: blaming the database ...

I built a local-first linter for vague release notes

Release notes often describe a change with phrases such as “improved performance” or “fixed several issues.” Those phrases sound finished, but they do not tell a reader what changed, who is affected, or whether any action is required. I built ReleaseProof to check that narrow problem. It takes two pieces of text: Change evidence, such as PR titles, issue summaries, test results, or a short dif...

Server Infrastructure Analysis

The purpose is to understand how different server components work together to provide services to users. A server plays an important role in a web-based application because it receives user requests, processes them, communicates with databases and other services, and sends the required response back to the user. Through this learning task, I gained a basic understanding of how server infrastructur...

My AI-Written Test Suite Hit 94% Coverage. Then I Mutated the Code.

I have a small Python library that parses CSV files and extracts course schedules. It has no tests. I know, I know. So last week, I decided to see if a free model could write them for me. I used MonkeyCode's free model access and free server. Disclosure: This article was prepared as part of MonkeyCode's product outreach. The goal was simple: generate a test suite for my library, run it, and meas...

Setting up an IPv6 only VM

Too many applications are still using IPv4 only, which is a shame as IPv6 was standardised ~28 years ago. If you want to check if your application is IPv6 ready, best thing is to have a server or docker/podman network which is IPv6 only. I'm showing how to set up both variants here. Setting up RedHat 10 for IPv6 only Note Root access is, of course, required for all these co...

Running LM Studio Locally Doesn't Mean It Never Connects Out

When we say “local LLM,” it is easy to mentally translate that into: Everything stays inside the PC. For inference, that can be true. But the application running the model is still an application with network-capable features. LM Studio, for example, may need connectivity for things such as: searching for models downloading models downloading runtimes checking for application updates It ...
