FlashVSR on an RTX 5060 Ti: From 480p Input to 1728×960 Video, Plus Every Pitfall I Hit

Mon, 10 Aug 2026 10:00:00 +0800

A note before we start

“Make a 480p video clearer” sounds like a simple resize operation. In practice, video super-resolution is closer to asking a restorer to repair hundreds of neighboring photographs while making sure faces, text, lighting, and motion do not jump from frame to frame. This post records a complete FlashVSR_plus experiment on an RTX 5060 Ti: compatibility checks, portable Miniconda setup, model download, source-level bugs, FFmpeg audio muxing, and reusable Windows, Ubuntu, and macOS scripts.

The FlashVSR_plus build used here is a community variant rather than the official upstream repository. Commands and flags can change between versions. Paths in this article are public examples; the original video, model cache, and raw terminal logs were not uploaded.

Computers Rarely Break “Out of Nowhere”: Read Logs Like a Detective

Wed, 29 Jul 2026 20:30:00 +0800

The short conclusion

Computers rarely fail without leaving a trace. A disk gradually fills up. A service emits warnings before it exits. A DNS lookup fails before a browser reports a timeout. A process starts and stops several times before a user sees a broken page. The practical skill is not to reinstall everything after seeing a red error. It is to ask five detective questions: When did it happen? Which object was involved? How serious was it? What happened before and after it? Can the result be verified after the fix?

This article explains logs as a computer’s diary instead of presenting them as mysterious engineering jargon. It uses real collection output from Windows 11, Ubuntu 26.04, and macOS 26, provides three native read-only collectors, and shows how to give the same evidence-first workflow to an Agent. A child should understand most of the story; an engineer can still reuse the commands and the reasoning pattern.

Restart Is Not Magic: Why Turning a Computer Off and On Seems to Fix 99% of Its Problems

Wed, 29 Jul 2026 08:00:00 +0800

The short version A restart is not magic, and it does not repair every fault. It is closer to emptying a room that has been used for months without cleaning: borrowed items are collected, people take fresh queue numbers, temporary notes disappear, and doors and appliances are initialized again. The system returns to a cleaner and more predictable starting point. When “restart fixed it” is true, the fault is often in volatile state, not in permanently damaged hardware, a configuration that is always wrong, or an application whose root cause has disappeared.

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.

I Put Docker in a Control Room: Portainer CE 2.39.4 Deployment, Daily Use, and Real Traps

Fri, 10 Jul 2026 15:30:00 +0800

Bottom line first

Portainer does not replace Docker. It is a control room for a Docker host. Docker Engine remains the machinery; Portainer organizes containers, images, networks, volumes, and Compose stacks into a web dashboard.

I ran an isolated deployment of portainer/portainer-ce:2.39.4, initialized it, connected the local Docker environment, inspected the dashboard, filtered a disposable container, and created a demonstration stack. The installation is one docker run command. The important lessons are broader: persist /data, understand that /var/run/docker.sock is highly privileged, and never expose the management interface to an untrusted network without protection.

This article contains no complete IP address, real host name, private domain, administrator password, token, cookie, private registry address, or production container name. The screenshots use disposable names, and the container address is redacted.

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.

Stop Clicking Remote Desktop: Let AI Agents SSH into Windows Instead

Wed, 13 May 2026 08:10:00 +0800

The short version

An AI agent does not need Remote Desktop, VNC, or a proprietary remote-control tool to operate a Windows machine. For many workstations, lab machines, development PCs, and internal servers, the cleanest path is to enable the built-in OpenSSH Server on Windows and connect from Linux or macOS with a normal command: ssh <user>@<windows-host>.

There are only three things to get right. First, install and enable OpenSSH Server on Windows 10 or Windows 11. Second, generate an SSH key on Linux or macOS and place the public key on Windows. Third, if the target account belongs to the Windows Administrators group, put the public key in C:\ProgramData\ssh\administrators_authorized_keys and lock down the ACL with icacls. After that, an AI agent can run PowerShell, copy scripts, collect logs, install tools, and perform repeatable maintenance through the same SSH workflow it already uses for Linux.

All hostnames, addresses, usernames, screenshots, and commands in this article use generic placeholders. No real internal addresses, usernames, machine names, tokens, keys, or private paths are included. Replace placeholders such as <user>, <windows-host>, and <windows-ip> with values from your own environment.

Java Spring Boot JNI Native Library Loader

Sat, 27 Mar 2021 16:37:31 +0800

Because Java needs to stay cross-platform, I wrote a cross-platform JNI native library loader.

Simple Implementation

Determine whether the current system is Windows, Linux, or MacOS from the os.name environment property.
If it is Linux, further determine whether it is CentOS or Debian.
Read the library files inside the jar package.
Filter the matching platform library files by file suffix: dll, so, jnilib, and dylib.
Copy the current platform’s library file to the system temporary directory java.io.tmpdir.
Load the library using System.load.

Here we recommend some software commonly used in the Windows environment of this site. There are no recommendations. If you don’t like it, please close the page. This software is equivalent to Windows version 应用市场, but does not include any bundled software. *Tencent officially closed the download of this independent version of the software N years ago (N>3). For the application market, it is obviously not cost-effective to install an additional Tencent Computer Manager.

How to run N2N-compilation using Windows

Fri, 15 Jan 2021 14:26:49 +0800

According to Building说明 of N2N官方网站, the software required for Windows compilation is Visual Studio,Cmake,OpenSSL。 I got a headache when I saw Visual Studio. This software is very difficult to install. So I chose cross-compilation, that is, using the Linux environment to compile Windows exe and dll files. #Compiled files Compilation environment: Contains edge, supernode, openssl链接库 (necessary for n2n operation), tap-windows安装包 (necessary for n2n operation, Win7&Win10) Prepare the compilation environment Use yum to install necessary software, the following is the author’s reference document wget https://download.
