There’s nothing more frustrating than launching Roblox on your Mac, only to see a ban message pop up. Whether it’s a 7-day IP ban, a permanent account ban, or a hardware ban (error 0x1), being locked out of your favorite game ruins the fun. But here’s the good news: most Roblox bans on Mac are…

If you’ve ever downloaded data from an API, backed up app settings, or imported data into a tool, you’ve likely encountered .json files. JSON (JavaScript Object Notation) is a lightweight, human-readable data format used universally for data exchange—from social media APIs to app configurations. But for many users (especially beginners), the biggest question is: how…

If you’re a developer, tester, or anyone working with APIs/web services, curl post is one of the most essential commands in your toolkit. Curl (Client URL) is a command-line tool that lets you send HTTP/HTTPS requests directly from the terminal—and the POST method (curl post) is used to submit data to a server (e.g., sending…

For developers working with OpenAI Codex (or similar AI coding assistants), codex config.toml is more than just a configuration file—it’s the “control panel” that dictates how the tool behaves. Whether you’re fine-tuning AI response parameters, managing API keys, or configuring network access (like proxies for global resources), config.toml is where all these settings live. Yet…

If you’re a developer or DevOps engineer, you’ve likely stared at your server logs and seen it: the 499 status code.

The Silent Gatekeeper You Never Knew Existed Your ad campaign is running. Budget is flowing. Click-through rates look amazing. But conversions? Zero. Your checkout process works perfectly in testing. But real customers? They’re abandoning carts at 78%. Your legitimate web scraping operation—fully legal, fully ethical—keeps getting blocked. No explanation. Just silence. Welcome to the world…

Why This Investigation Started Three months ago, my e-commerce automation business burned through $4,200 on proxies that promised “99.9% uptime” and delivered connection failures during Black Friday peak hours. Accounts got banned. Orders failed. Revenue evaporated. That failure cost me $23,000 in lost sales. So I did what any rational person would do when they’re…

As of December 2025, the Qwen series from Alibaba Cloud, particularly Qwen3 models, excels in agentic capabilities, enabling autonomous task execution through tool calling, planning, and memory. The official Qwen-Agent framework simplifies building LLM-powered agents, supporting features like function calling, Model Context Protocol (MCP), code interpretation, retrieval-augmented generation (RAG), and GUI deployments. This guide details…

Managing multiple TikTok accounts is crucial for cross-border marketing, yet many people encounter unexpected account bans. The core reason lies in TikTok’s risk control system detecting “shared IP addresses” or “identical device fingerprints,” leading to a judgment of associated fraud. To solve this problem, the key is to select a compliant IP tool and a…
