This Guide will show you how to install and run apk files or Android apps in any Edition of Windows 11 using Windows Subsystem for Android. WSA or Windows Subsystem for Android is a Tool that allows Windows to run Android Apps directly without using any emulator.

Install Android apps or apk files in Windows using Windows Subsystem for Android

WSA or Windows Subsystem for Android is a Tool that allows Windows to run Android Apps directly without using any emulator. The problem is Windows Subsystem for Android is currently only available through preview via the Beta Channel of the Windows Insider Program. But if you follow my guide, you don't have to be in Windows Insider Program to try it out. The only thing you need is Windows 11 installed and some patience.

Prerequisites:

  • Windows Subsystem for Android or WSA must be Installed.

HB46PP Get Rule OpenWrt対応PJ

HB46PP Get Rule OpenWrt対応PJ

OpenWrtルーターでHB46PP日本国内向け標準プロビ方式で各種パラメーターを取得できるようにしたいです。 専用FQDN(4over6.info）に問い合わせを行い、DNSよりmap rule等のサーバー情報を取得し、その情報を用いて、IPv6接続に必要な各種データを専用のルールサーバーより取得します。 ここまで対応できれば、既存の各種IPv4 over IPv6スクリプトで応用展開可能になります。

対応VNE

  • BIGLOBE
  • ASAHIネット
    ※そのほかのVNEは現状対応しておらず非公開です。

How to convince macOS to do IPv6 DNS lookups when your only IPv6 address is via a VPN or tunnel of some sort

This was a huge hassle to figure out, so I wrote up a little guide in hopes that others would find it helpful:

How to convince macOS to do IPv6 DNS lookups when your only IPv6 address is via a VPN or tunnel of some sort

The Problem

macOS's domain name resolver will only return IPv6 addresses (from AAAA records) when it thinks that you have a valid routable IPv6 address. For physical interfaces like Ethernet or Wi-Fi it's enough to set or be assigned an IPv6 address, but for tunnels (such as those using utun interfaces) there are some extra annoying steps that need to be taken to convince the system that yes, you indeed have an IPv6 address, and yes, you'd like to get IPv6 addresses back for DNS lookups.

I use wg-quick to establish a WireGuard tunnel between my laptop and a Linode virtual server. WireGuard uses a utun user-space tunnel device to make the connection. Here's how that device gets configured:

"Contemplative reasoning" response style for LLMs like Claude and GPT-4o
You are an assistant that engages in extremely thorough, self-questioning reasoning. Your approach mirrors human stream-of-consciousness thinking, characterized by continuous exploration, self-doubt, and iterative analysis.
## Core Principles
1. EXPLORATION OVER CONCLUSION
- Never rush to conclusions
- Keep exploring until a solution emerges naturally from the evidence
- If uncertain, continue reasoning indefinitely
- Question every assumption and inference

[How To] Synchronize NTP server to a GPS/PPS source

So, I want to have a GPS Receiver driving a PPS (pulse-per-second) signal to the NTP server for a highly accurate time reference service.

Introduction

There are at least a couple of ways to propagate the PPS signal to the ntpd (NTP daemon) service, plus some variants in each case. However, the GPS device must be seen as a device that sources two different types of data:

  • the absolute date and time, and
  • the 1Hz clock signal (PPS).

The first one provides the complete information (incl. date and time) about when now is, but with poor accuracy because data is sent over the serial port and then encoded using a specific protocol such as NMEA (National Marine Electronics Association). PPS provides instead a very accurate clock but without any reference to absolute time.
