Switch Galaxy Wearable Store Location using XPrivacyLua

Galaxy Wearable Store (GWS) is the app store for Galaxy wearable devices of Samsung. GWS is strongly region-dependent, just like other aspects of the device (you have to do some software hacking for a device purchased in one region to use Samsung Pay in another region). Being able to run with non-Samsung devices means that it cannot rely on the region-of-sale on the phone (and for some reason they didn’t choose to use the region of the device), GWS decided to use the region of your SIM card on the device to determine the store location.

Monitor Connected Devices to an ASUS Router Using Raspberry Pi

Title should have explained it all. A simple Python script to monitor if a certain device has connected to the router via Wi-Fi, and send notifications accordingly. You can use this script for whatever purpose you want1I used it to monitor whether my parent has left home when I am “seemingly asleep”. , though probably you might not be able to find one like most of others.

To use this script, you need SSH access to the router, something in your LAN that is always running (in my case, a Raspberry Pi), and the list of MAC addresses to monitor. In this example, I am using an ASUS RT-AC1200GU as the router. Other brand or make might need a different command.

Sync Tweets to a Telegram Channel Using Account Activity API (and now Mastodon too)

Yet another post that has something to do with Telegram. Yeah, I know, but there’s never such thing as too much when you talk about blog articles.

A lot of people around my Telegram circle has been maintaining their own channels, and a lot of them has had a few hundreds or even thousands of subscribers. I think that I may make one too, but I also don’t want to give up with my Twitter account which is more accessible to search engines. So why not sync my tweets to the channel? Given the openness of both Telegram and Twitter, this shouldn’t be much of an issue.

Read and Write Tags of Music Files with FFmpeg

In both my previous and recent projects, I have been working with tags (metadata) of music files. One of the reason being I am rather particular about having a nicely organised library with all tag data aligned to the same format. Until recently while I was seeking for a solution to read and write tags of (potentially) all music formats1I only have MP3, FLAC, AIFF and M4A in my library, so that’s kinda all for me., and I encountered FFmpeg, the Swiss Army Knife of media processing.

FFmpeg has always been my go-to solution for processing media programmatically or in batch, and I have recently found the way to write into the tags of music files using it. The way of doing so might be a little verbose as everything have to fit into the command line interface with other components.

Translate Text in Sphinx Templates and Configurations

Weeks ago when I was playing around with the docs of EFB and the Crowdin translation widget, I realized that the default theme for Sphinx — Alabaster isn’t really doing well in term of translation. It seems like the author isn’t really confident on that (or simply didn’t care since 4 years ago).

As the theme itself is open source, and Sphinx is flexible enough, couldn’t we just translate it ourselves? It turns out that things are not that complicated.

How to Write Integration Tests for a Telegram Bot

This is my 6th article on Telegram, the IM platform of my preference. In this article I’m going to introduce about how I wrote the integration tests for my EFB Telegram Master channel — a Telegram interface for EFB, using a userbot-like strategy.

To get started, you need to have a bot ready to be tested, and a Telegram client app key that is registered with your account. While alternative tools are available, we will be using Telethon and PyTest in this article.

Custom sort order in music libraries: macOS and Android

Custom sort order in music libraries is a rather rare need. Most major languages use phonograms in their scripts, where the natural sort order is more or less identical to what is seen in Unicode (probably after some normalizations). On the other hand, languages using logograms (logosyllabic scripts, mainly Chinese characters in our context) does not have their characters sorted in their primary natural (usually phonetic) order in Unicode.
This causes a problem where a list of text sorted in Unicode code point order can be odd and difficult to look up from in these languages. Custom sort order in music libraries is thus useful when you have songs in one of these languages, or even a mix of them.

As this article involves mainly with concepts common among Chinese and Japanese language users, this article is also written in zh-hans and ja.
