Take Back Your Remote Desktop: Deploying an All-in-One RustDesk Server Safely

Fri, 10 Jul 2026 22:00:00 +0800

The short version

RustDesk is an open-source remote desktop application designed with self-hosting in mind. When two clients can reach each other directly, screen and input traffic can use a peer-to-peer path. When that direct path fails, a relay server forwards the encrypted traffic. Hosting the server yourself does not eliminate servers; it puts device registration, relay routing, keys, accounts, and logs back under your control.

This guide uses the community-maintained lejianwen/rustdesk-server-s6 image to place the RustDesk OSS hbbs and hbbr services together with a community API and web administration layer in one container. It is a convenient option for homes, labs, and small teams, but it is not an official RustDesk all-in-one distribution. Evaluate the community image, pin a tested tag or digest, back up its persistent data, and rehearse upgrades and rollbacks before treating it as production infrastructure.

Windows Finally Gets Native Linux Commands: Microsoft Coreutils Replaces WSL, Cygwin, and Git Bash

Sat, 27 Jun 2026 08:00:00 +0800

Let me ask you something:

Have you ever tried to grep a log file in Windows Terminal, only to be told that grep is not a recognized command? Tried to use find to locate files, only to discover that Windows’ find is a completely different beast from Linux’s find? Written a cross-platform script that works perfectly on Linux, then falls apart the moment it touches Windows?

It’s not your fault. It’s the “Berlin Wall” between Windows and Linux command lines.

The good news? Microsoft just tore that wall down. In late 2025, Microsoft open-sourced coreutils on GitHub — a native Windows port of the essential Linux command set. No WSL. No Cygwin. No Git Bash. Just one winget install command, and your Windows terminal suddenly speaks fluent ls, grep, sed, and awk.

OpenClaw Upgrade Guide: From Beginner to Expert

The short version

OpenClaw is a powerful personal AI assistant that supports multiple messaging channels and AI models. Upgrading OpenClaw is actually very simple — the most recommended way is to use the openclaw update command. This article will详细介绍 various upgrade methods, including switching from npm package installation to git source installation, as well as verification and rollback strategies after upgrading.

All examples in this article use public projects, public links, and placeholders. No real server addresses, accounts, tokens, business configuration, or private network details are included.

Stop Worshipping Agent Frameworks: 12-Factor Agents as an Engineering Baseline

Sat, 23 May 2026 14:50:00 +0800

The short version

12-Factor Agents is not an installable agent framework, and it is not a Skill for Codex, Claude, Cursor, or any other agent runtime. It is better understood as a set of engineering principles for the AI era. When a system made from a large model, a tool list, and a while loop reaches the familiar 70% or 80% quality bar but refuses to become production-grade, these principles tell you where to look: prompts, context, structured outputs, state, human approval, error compaction, control flow, and recovery.

The best part is that it does not romanticize agents. It says, in effect, that reliable agents are mostly software. The LLM is powerful, but it should live inside a system that is observable, interruptible, recoverable, auditable, and testable.

All examples in this article use public projects, public links, and placeholders. No real server addresses, accounts, tokens, business configuration, or private network details are included.
