The Ultimate Directory Image Conversion Tool Made with Python

Sat, 16 Mar 2024 18:26:25 +0700

TL;DR / Geek Summary:

Python-powered recursive image mass-converter utilizing the Pillow and tqdm libraries.

Supports bidirectional logic: WebP-to-JPG and multi-format-to-WebP (compression-focused).

Zero-install standalone deployment optimized for legacy Windows environments (Win7+).

# Introduction

Batch Delete Bilibili Following List

Sun, 09 Apr 2023 00:00:00 +0700

TL;DR / [Geek Summary]:

Ditch the manual grind; automate unfollowing with a JS snippet in the browser Console.

Logic: Uses jQuery selectors to target “Unfollow” buttons and a setInterval loop to trigger them.

Geek Move: Hit F12, paste the code, and clear your feed clutter in one shot.

# How to Quickly Unfollow UP Masters on Bilibili?

When you engage in “follow-for-follow,” you might find your feed cluttered with unwanted videos. Or perhaps you accidentally followed a bunch of UP masters when registering a new account.

You then realize that Bilibili doesn’t have a batch unfollow feature, forcing you to click them one by one (how annoying!).

var ms = 300; // Pause for 300 milliseconds
var ii = 0;
var xx = $(".be-dropdown-item:contains('取消关注')");
console.log("Following", xx.length, "UP masters on this page!");
tt = setInterval(function(){
 if (0 <= ii && ii < xx.length) {
 xx[ii].click(); // Automatically click {Unfollow}
 } else {
 clearInterval(tt); // Stop operation
 console.log("OK! No more UP masters on this page!");
 }
 ii += 1;
}, ms+ii*10); // Pause milliseconds before the next click, interval increases incrementally

Using Chrome browser as an example:

Press F12.
Go to the Console tab.
Paste the code above.
Press Enter.

This will quickly unfollow all 20 UP masters on the current page.
