Introduction: The Hard Truth About IoT Ingestion for Telematics Building a reliable IoT ingestion server for telematics data isn’t about handling the first byte of data—it’s about surviving everything that comes after. In my experience with a Python-based pipeline ingesting TCP sensor data from heavy equipment, the real challenges emerged far beyond initial reception. The pipeline—Python → local disk spool → RabbitMQ → PostgreSQL—looked straightforward on paper. Reality, however, demanded a ...

If you run a one-person consultancy, late invoices cost you twice: once in cash flow, and again in the 20 awkward minutes it takes to write a reminder that's firm but doesn't burn the relationship. This tutorial builds a Claude Code skill that does the awkward part: it reads a plain-text invoice list, works out who is overdue, and drafts the right reminder for how late each one is. You still press send. You need Claude Code installed ( https://code.claude.com/docs/en/setup ). 1....

Your customer taps “Place order.” The request crosses your app, an API gateway, a native backend, a payment service and a database. Your operations team needs to see that path in the same tracing system it uses for the rest of the company. Neither the client app nor a compiled Java server should disappear from that picture. What is Codename One? Codename One is an open-source framework for building native iOS, Android, desktop, and web apps from a single Java or Kotlin codebase. Learn more ...

TL;DR: RAG metrics fall into three categories. Retrieval metrics (hit rate, recall@k, MRR, nDCG) tell you whether the system retrieves the right chunks. Generation metrics (faithfulness, answer relevancy, correctness) tell you whether the LLM used them well. Operational metrics (cost, latency, storage) tell you if you can afford to run it. This guide explains each metric with an example and tells you which ones to focus on for your setup. There’s no shortage of RAG metrics. Libraries expose ...

I recently built MoneyMov , a free personal finance tracker to help people understand where their money is going. The idea was simple: Know where your money moves. Instead of building another complicated finance application, I wanted to create something simple enough for everyday use. What Is MoneyMov? MoneyMov is a personal finance tracker where users can manage their: 💰 Income 💸 Expenses 📊 Spending categories 📈 Investments 🤝 Committees / Bachat 💵 ...

Blazor is a web UI framework from Microsoft that allows developers to build interactive web applications using C#, .NET, and Razor components. A Blazor component is a reusable part of a user interface that can contain HTML markup, C# logic, data binding, event handlers, and conditional rendering. Let's understand this with a simple example of a product details component. <h3>Product Details</h3> <div class="card shadow-sm p-3"> <h5>@productName</h5...

Type a new { } in C# and you create an object with no type you can name. var row = new { Name = customer.Name, Total = customer.Total }; gives you a row you can read .Name and .Total off, pass to LINQ, and compare for equality — but try to write its type and you cannot, because there is no keyword for it. That absence is a source-language illusion, exactly like ?. having no IL opcode. In the compiled assembly the anonymous type is a perfectly ordinary class. The compiler just synthes...

I've been playing around with a new kind of isomorphic music keyboard that uses a base-12 notation, and wanted some sheet music to learn some new music for it. The idea is to represent each note in 12-TET as a number, so N ∈ (0,1,2,3,4,5,6,7,8,9,X,Y). I used codex to build a music score rendering backend based on MuseScore with custom note heads that display the pitch class of each note. I've found it pretty helpful for learning how to play my own instrument, so wanted to share in case anyone e...

Guitoro is a free browser guitar using recordings of real instruments. You can strum with your keyboard, mouse, or touchscreen, choose acoustic, classical, electric guitar or bass, and see chord fingering and each stroke. Song practice can be slowed to 20%, and there are free chord tools and tuners. No signup or download. I would love feedback on how the strumming feels and sounds.

With customizable “faces,” this 7-inch smart display is a unique hybrid between an iPhone and an Apple Watch.

The team behind director Takashi Yamazaki’s new film created their kaiju roars by setting up speakers on top of an outdoor dam. The people walking by weren’t prepared for what they heard.
