JavaScript Debugging: the Complete Guide

An effective JavaScript debugging process is vital for any web developer. Over 95% of the web is built with JavaScript code, but the language carries its own distinct challenges due to its unique runtime model. This guide will help you master these challenges and become truly fluent in the Internet’s first language. You’ll learn about: You’ll leave with a process that works in any case, no matter how edgy.

Top Static Site Generators for 2025

Static site generators have never been more relevant. AI search tools favor fast, pre-rendered content. Hosting costs are near zero. Build tooling has matured to the point where shipping a production-ready static site takes hours, not weeks. But while the benefits of SSGs are clear, choosing the right SSG for your business can be much more tricky. There are lots of competing options, all with their own pros and cons.

A Beginner's Guide to Turning Old Photos Into Videos

Somewhere on a hard drive or in a shoebox, there are photographs that matter to you - a grandparent on a doorstep, a holiday nobody documented properly, a childhood pet. They get scanned, admired for a moment, and filed away again. Motion changes how those images land, because movement restores something a still frame flattens: presence. This tutorial assumes no editing experience. You will learn what photo animation actually does, how to prepare an archive image, and how to finish a short, respectful memory clip in a single sitting.

Diagnose Serial N+1 API Calls With Tempo + proxymock

One API request took 302 milliseconds. Nothing failed. CPU was mostly idle. The response was correct. The trace made the problem obvious: eight inventory calls, each waiting for the previous one. But the trace could not tell me why the application made eight calls, or whether changing their execution would preserve the response. It showed the shape of the wait, not the input that created it.

The Pod Was Cheaper. The Service Wasn't.

A smaller Kubernetes pod can lower allocation cost while completing less work. Green status codes and matching schemas can hide it. This walkthrough combines OpenCost allocation data with proxymock behavior and performance evidence. A candidate passes only when behavior and throughput hold while unit cost falls.

Two confident fixes missed this production bug

Every new signup posts a message to our Slack. The format is dull and reliable: Overnight this week one arrived like this: That trailing nothing was the entire incident. No error logs, no alerts. A returning user had signed up, our signup service had attached them to a tenant we deprovisioned back in December, and the only symptom in the whole company was a Slack message that ran out of words. Their company's email domain still pointed at the dead tenant, so instead of a fresh workspace they landed in a corpse: domain mapping still live, cloud infrastructure long gone. I'm on call this week, so I pulled the thread.

How to Feed Consolidated Financial Data into Power BI

Power BI is a reporting layer. It renders whatever data reaches it, but it doesn't harmonize a chart of accounts, eliminate intercompany transactions, or trace a number back to the journal entry across ten different ERPs. Keboola is the governed data foundation that does that work upstream, then feeds consolidated, audit-ready financials into Power BI. No rip-and-replace, no new reporting tool to learn.

What Private Equity Firms Need from a Portfolio Reporting Tool

Most portfolio reporting tools assume the data underneath them is already clean and comparable across every portfolio company. It rarely is. A fund with twenty portfolio companies usually has twenty different ERPs, twenty different charts of accounts, and a reporting team that spends the week before every LP update reconciling numbers by hand.

Kong AI Gateway Applies NVIDIA NeMo Switchyard Across Model Traffic

Every team running production LLMs has had the same idea: not every request needs the frontier model. Intelligent model routing (or LLM routing)— choosing a model per request on criteria such as task complexity, cost, latency, or quality — enables more efficient model usage.

Practice what you Pact : Catch breaking API changes before production in the SmartBear MCP

There’s something satisfying about contract testing the contract-testing tool. The SmartBear MCP Server is the integration layer between AI coding assistants and the PactFlow API, so when we decided it needed Pact consumer tests of its own, we were subjecting our own code to the same standards that we recommend.
