CheckAO3

I added a few more features:

💥saving links to the author's page

🦾a diagnostics button with the ability to manage snapshot memory and clear storage

💫viewing all changes based on the oldest snapshot

It wasn't easy, but it was fun

small Obsidian plugin experiment

I made a small plugin for Obsidian that helps convert underscore-style Markdown formatting to HTML tags.

The plugin scans notes for patterns like _text_, *text*, or **text** and converts them into <i> and <b> HTML tags.

It can:

scan the current note or the entire vault

show a badge next to files that contain problematic formatting

generate a report with all affected notes

convert formatting directly from the file menu or report panel

It also skips fenced code blocks and inline code so code snippets aren’t modified accidentally.

I mostly built it because I sometimes need notes to use HTML formatting instead of Markdown and doing it manually across many files gets annoying.

Source code and instructions are in the repository.

I added a plugin for replacing "text" quotes with «text» for myself. I noticed I often do this manually. Now all incorrect quotes are displayed in blue 🐸

Been working on an extension for Chrome that tracks your Ao3 history (doesn't send it anywhere, just stores it in your browser) simply because I'm frustrated with how hard it is to search my own history on the site.

Is there any ability/feature you'd like to have in such a thing?

AO3 stats track

I I made a small Firefox extension to track AO3 stats.

It keeps local snapshots of your stats, so you can see how hits, kudos, bookmarks and comments change over time.

With its help, the author can track the statistics of his own works.

You paste in an author link, and it pulls the numbers from the author’s works pages without opening the individual fic pages themselves. It shows hits, kudos, bookmarks, comments, and how those numbers change over time, so it’s easier to see what’s moving without checking everything by hand.

I made it for myself, so the extension is not officially registered with Mozilla, but anyone can use it if they download the source code.

A more detailed description and source code are available on GitHub.

This is a quick and easy option if you don't want to take screenshots and remember numbers, or if you have a lot of work to do.

The extension doesn't require registration or entering your own credentials—it simply opens the author's page and retrieves publicly available data. Therefore, it doesn't inflate views of your work.

Right now it’s fully local, not registered in Firefox, and can only be used in debug mode as a temporary add-on. Nothing is routed through a separate website, and the data stays in the local Firefox profile.

I found and fixed a bug that was causing the 24-hour difference calculation to be displayed incorrectly. Added tests. Someday I'll start writing tests before, not after…but not today 😫🐸

Cipher Desk

I built a small offline encryption tool for Windows called Cipher Desk.

It’s a lightweight desktop app for encrypting text, images, and documents locally. Everything runs on the machine — no external services and no cloud storage involved.

The application uses:

AES-256-CBC encryption

HMAC-SHA256 authentication

PBKDF2-SHA256 for password derivation

Encrypted files are stored in a simple container format with the .cdesk extension.

What it can do:

encrypt text into JSON

encrypt images and documents into .cdesk

restore the original file extension during decryption

preview images in the interface

open decrypted documents directly from the app

generate strong passwords or passphrases before encryption

The password generator supports:

random passwords

multi-word passphrases

configurable length

selectable character groups (A-Z, a-z, numbers, symbols)

The project is written mostly in PowerShell + WPF, and builds into a portable Windows desktop application.

The whole project works fully offline and doesn’t depend on external services.

Source code and more details are available on GitHub.

MusicGen

Small experiment: generating passwords from audio fingerprints

Don’t want to store passwords in a notebook? Don’t want to overthink how to encrypt something before sending it to a friend?

So I built a small experiment called MusicGen.

It generates deterministic passwords from audio.

Same sound → same password.

Upload a piece of sound — a song fragment, a voice message, or even two minutes of your cat screaming — and the app converts its acoustic fingerprint into a password.

What it does:

generates deterministic passwords from WAV and MP3

supports two fingerprint modes: Exact and Robust

lets you preview the audio before generation

trims large audio files directly in the browser

has a standalone offline desktop version

Tech stack

Next.js + React + TypeScript (frontend)

FastAPI + Python (backend)

Electron for the desktop build

The idea is simple: turn sound into a stable acoustic fingerprint, hash it, and use the result as a password.

⚠️ Important: this is a creative tool, not a replacement for a real password manager. Don’t use it for banking, crypto wallets, or anything critical.

But for small things, shared secrets, or just experimenting with audio fingerprints, it’s a fun project.

Source code and details are available on GitHub.
