Three Test Levels for One CLI Subcommand

7 out of 7 tests pass. That number is boring and exactly correct. Adding a CLI subcommand sounds trivial until you count the actual failure modes: the subparser is not wired up, the func is not registered, the dry run flag is silently swallowed, the argument parser crashes with a useless error. Any of those can bite you. The only way to know they do not is to test at three distinct levels, which is what this commit actually does. Here is what wiring warmup eval looks like in practice. ...

What is World App? Inside the wallet, ID and mini apps

If you have spent any time reading about World ID or Worldcoin and found yourself more confused after, you are not alone. The naming is dense. World App, World ID, Worldcoin, World Chain, World Network. They are related but they are not the same thing, and most explainers either treat them as interchangeable or go so deep on one that the others disappear. This article separates them clearly. It starts with World App because that is the thing most people encounter first, then works outward ...

How I get marketing sites to 100/100 on mobile Lighthouse (the exact Astro setup)

Open zivaro.co.za in PageSpeed Insights on the mobile profile. Performance 100, Total Blocking Time 0ms, and that is on the Moto G Power, Slow 4G profile, which is about as unkind as the test gets. The four demo sites in my work gallery sit around 99 on the same profile. I am not posting that to brag. I am posting it because a perfect mobile score is not hard, it is just unfashionable. Most agency marketing sites score in the 50s to 70s on mobile, and the reason is almost never the thing pe...

How to Translate Your WordPress Site into 50+ Languages (Free Plugin, No Code)

Most WordPress translation solutions ask you to restructure your site. WPML adds a language switcher and creates separate post copies for each language. Polylang does the same. Both require you to manage translations page by page, keep multiple versions of every post in sync, and deal with plugin conflicts when your theme or other plugins update. The WeLocale plugin works differently. There is no per-page translation workflow, no duplicate posts, no theme editing. You install the plugin, conn...

Stop Writing Angular HTTP Services by Hand

Generate signal-native, tree-shakeable API clients from any OpenAPI spec — in one command. You have an OpenAPI spec. Your Angular app needs to call those endpoints. What do you do? The usual answer is one of these: Write HttpClient calls by hand in a service, duplicating type information already in the spec Use a generic codegen tool that emits a 2,000-line service class full of endpoints you'll never call Spend a sprint wiring up interceptors, managing base URLs, and keepin...

DiffusionGemma 26B 登陸 M2 Max:MLX 吞吐量實測與 Context 極限挑戰

為了找到一些在地端也能讓 Agent 有無限 token 自由的毒駕的方法,原本用手邊的M4 24GB Mac 上嘗試執行 DiffusionGemma 26B,卻悲慘的連 1,000 tokens 的 Context 都撐不住,直接迎來 OOM(記憶體不足)的悲劇。 換到 M2 Max 96GB 後,終於可以展現出它應有的實力? 我改用MLX(mlx-vlm 0.6.3),過程中雖然踩了 MXFP4 的量化 Bug 並手動處理了 Patch,但最後成功在4-bit 格式下跑完整套 Benchmark。 本文記錄這幾天 DiffusionGemma 26B 在 Apple Silicon 上的吞吐量極限、Prompt 載入成本、以及 Context 長度與對記憶體的代價,同時,我們也會拿這些實測數據來作為後續 GH200 與 GB10 跨平台效能對比的 Baseline 系列首篇文章。 兩個量化版本 第一次 deploy 踩到 MXFP4 的 dequantize bug,後來換 4-bit 才穩定跑完整個 benchmark: ...

Stop Vibing. Start Understanding.

Stop Vibing. Start Understanding. Over the last few years, AI has changed how developers write code. Today, you can describe an application in plain English and receive hundreds of lines of working code in seconds. At first, this felt like magic. But after spending more time building projects with AI, I noticed something concerning. Many developers can generate code. Far fewer can explain it. Even fewer can debug it when something breaks. We've reached a point where a de...

Structured Logging That Actually Helps Debugging at 3 AM

Most logging is written for the person who wrote the code. The author knows the system, knows what the messages mean, and can fill in context from memory. Then at 3 AM, an alert fires, and the person debugging is someone else — or it's the author at month six, who has forgotten everything. Logs that work at 3 AM are different from logs that look good in a unit test. The difference is structure, context, and the discipline to leave breadcrumbs that the future-you will actually be able to follo...

Stop Fighting React Native File Systems: Meet rn-file-toolkit

If you've built React Native apps for long enough, you've probably fought with file downloads, uploads, and filesystem management. Historically, the community relied on rn-fetch-blob or react-native-fs . While these libraries were absolute lifesavers in their prime, they haven't aged gracefully. They often lack active maintenance, struggle with background persistence, and require a lot of manual boilerplate to manage things like download queues or multipart uploads. Even expo-file-sys...

7 GitHub Repositories I Recommend to Every AI Builder

The AI ecosystem is evolving so fast that keeping up with new frameworks, tools, and architectures can feel overwhelming. Over the last few years, I've explored hundreds of AI projects, frameworks, and repositories.

They help developers build real AI systems. Whether you're working on chatbots, agents, RAG pipelines, workflows, o...

How Expats in Dubai Are Losing Money Without Knowing It If you're an expat living in Dubai (or anywhere in the Gulf), you probably have bank accounts in at least two countries. Maybe three.
