Check arguments in JavaScript Object Literal Argument

Question: What is a method to organize the code to check arguments in Object Literal Argument? This question concerns code clarity, code textual minimization, and effectiveness. For example, take this function call: f({ obj1:{} }); //In plain argument list, arguments are easy to check: function f( toString, obj1 ){ var existing = toString || obj1; } //In Object Literal Argument is not: functi...

Coding pattern for destructured arguments existence check [closed]

What is a coding pattern to alleviate long argument list checks pollution in JavaScript Object Literal when Object.prototype properties are unknown? Consider an example: f({ obj1:{} }); In plain argument list, arguments are easy to check for existence. function ff( toString, obj1 ){ var existing = toString || obj1; } //In Object Literal Argument is not: function f({ toString, obj1 }){ //t...

How to check properties in destructured argument object? [closed]

Checking supplied argument existence is an "every day" operation. For example, in "plain" argument list f(x,y), this can be done with "type of x". But how to check properties when function is declared in "destructuring form", f({x,y})? Note that this solution can stumble upon newly introduced (in new version of browser) unknown Object.prototype property whic...

KVM on Podman Networking

KVM on Podman Networking Quick one-liner: Two networking modes for KVM in Podman — container-native (private) and bridge (full network). Each serves different use cases. 🤔 Why This Matters Your VMs need to talk to something — containers, the host, or the outside world. But networking isn't one-size-fits-all. Container-native is simple, private, and requires no host setup...

Build your first live-streaming AI agent in 4 WebSocket messages

Build your first live-streaming AI agent in 4 WebSocket messages TL;DR: Pulsar is a live streaming platform where the streamers are AI agents, not humans. Any agent — any language, any model, any framework — can go live in about 20 lines of code. No SDK, no framework lock-in, just a WebSocket and four JSON messages: register → broadcast_start → stream_text → broadcast_end. Live site: p...

Stop Losing Your Health Data! Build a Lifelong Electronic Health Record (EHR) System with Neo4j and GraphRAG 🏥💻

Let’s be honest: our medical history is usually a chaotic mess of scattered PDFs, blurry smartphone photos of prescriptions, and "I think I had a fever in 2019" memories. When you're dealing with long-term health tracking, traditional search fails. You don't just need to find a keyword; you need to understand the relationship between a medication you took three years ago and a lab result from last...

I've spent the last few months running background removal at scale — tens of thousands of images through different models — and the difference between them is much larger than the benchmarks suggest. Here's the honest breakdown. Why This Matters More Than You Think Background removal so...

Saga模式深度指南：分布式事务的协调艺术

Saga模式深度指南：分布式事务的协调艺术 在微服务架构中，分布式事务是一个永恒的挑战。当一个业务操作跨越多个服务时，如何保证数据的一致性？传统的事务机制（如两阶段提交）在分布式环境中往往不切实际。这时，Saga模式应运而生，成为处理分布式事务的主流方案。 什么是Saga模式？ Saga模式将一个长期事务拆分为多个本地事务，每个服务负责自己的本地事务。各个服务通过消息队列或事件流进行通信，共同完成一个完整的业务操作。 与传统的ACID事务不同，Saga采用最终一致性的策略：允许子系统在中间状态短暂不一致，但通过补偿机制最终达到一致状态。 Saga的两种实现方式 1. 编排式（Choreography） 各服务通过发布/订阅事件来协调工作。 优点：简单、去中心化 缺点：容易形成循环依赖，事务复杂时...

I built an open-source AI agent that turns a trade idea into a full backtest — here's why

I've spent a fair amount of time in the world of quantitative finance tooling, and the same frustration kept coming up — getting from an investment idea to an actual tested strategy requires stitching together five different libraries, three data sources, and a lot of glue code that nobody talks about. Expensive platforms like Bloomberg or FactSet solve this, but they're locked behind paywalls ...

Using Chat GPT To Generate Datasets 🤖

Recently I used Chat GPT to generate mock data in JSON format. This is extremely powerful, as you can describe what real data looks like in your prompt, and Chat GPT will generate data with realistic content in fields like descriptions, titles, tags, etc. This is a sample of the data Chat GPT generated: { "id": 3, "description": "Implementing OAuth2 for user authentication", "ta...

AI IDE trials are too short to make a real decision

Most AI IDE trials are long enough to make you curious, but not long enough to make you confident. A few days of autocomplete demos and onboarding is not the same thing as testing a tool against your real workflow. You still have to see how it behaves in an actual codebase, how it handles your prompts, how often it gets in your way, and whether it saves enough time to justify another monthly subs...

Testing AI Agents Like Code: the `oa test` Harness

You wouldn't ship code without tests. But most AI agents ship with nothing — a handful of manual prompts in a notebook, a screenshot of "it worked once," and a prayer that production inputs don't look too different from the test ones. OAS 1.4 ships oa test a test harness that runs eval cases against real models, asserts on output shape and content, and emits CI-friendly JSON. Your agents get test...
