How I Tamed Legacy Docker (v1.29) for Multi-Stage Microservice Builds

The Challenge: Modern Multi-Stage vs. Legacy Daemon Our goal was straightforward: standardize Dockerfile.base across our active microservices and gateways (auth, user, driver, booking, matching, payment, notification, web-bff, and mobile-bff) to produce consistent :jvm runtime images. However, legacy Docker v1.29.2 presented three hard constraints: No BuildKit Support: Modern cachin...

Stop Reaching for a Bigger Model. Fix the Prompt First.

Every time an AI feature disappoints, the reflex is the same: swap in the newer, bigger model. Sometimes that helps. More often, the same model would have nailed it if the prompt had actually told it what to do. I've watched teams burn a sprint on model comparisons when the real problem was a two-line prompt doing four jobs badly. The boring truth: for most day-to-day tasks, the gap between a wea...

Building a Simple Currency Converter in React with useState and useMemo

`` One of the best ways to learn React is by building small, practical projects. A currency converter is an excellent example because it introduces state management, user input handling, calculations, and performance optimization—all in a single application. In this tutorial, I built a simple currency converter using React that converts from USD to EUR, GBP, and JPY. For simplicity, I used fixe...

Magic The Gathering Card Border Relief with CSS

Azure Cosmos DB Flaw Exposed Platform-Wide Key That Could Access Any Database

A now-patched vulnerability in Azure Cosmos DB could have let an attacker escape the service's Gremlin query sandbox and obtain full read and write access to databases across customer tenants, according to Wiz. Wiz, which codenamed the chain CosmosEscape, said the exploit chain began with a crafted query against a Gremlin database controlled by the attacker. From there, code execution on a

Editing an ext4 Partition Directly from macOS (No Linux VM Required)

I lost the private key for a Raspberry Pi and needed to add a new public key to /root/.ssh/authorized_keys. The Pi's SD card was plugged into a Mac via a USB reader, so diskutil list could see the partitions fine — but the root filesystem was ext4, which macOS cannot mount. No spare Linux box, no VM set up, just Docker Desktop (which, on Apple Silicon, only gives you a Linux kernel inside its VM —...

How I built a multi-provider proxy for Grok Build!

How it works Grok Build → GrokRoute (:8083) → Agnes / Groq / Zhipu / Laguna / Ollama The proxy is a single Python file implementing the OpenAI /chat/completions endpoint with SSE streaming.

Enforcing Request Policy at the Runtime Boundary

In a multi-tenant business system, the dangerous query is often not obviously dangerous. A developer writes a useful request: Q.candidates().selectName() .selectEmail() .filterBySkill("Java") .page(1, 20) .comment("Query candidates").purpose("Load data") .executeForList(ctx); The request looks typed, generated, and harmless. But in a platform like Multi Talent, a cand...

We added a file-tree preview to our shadcn block library - does this make evaluating blocks easier?

While working on our shadcn block library, one thing always bothered us: a flat code preview doesn't really tell you how a block is structured. We ended up replacing it with a file-tree preview, so before installing a block you can see: which files are included how they're organized whether it's a simple component or a larger composition It feels much closer to browsing a GitHub repository than ...
