Tweet analysis

Issues Unicode spaces

Tweets are in Unicode format and different languages. You might want to convert all the different kind of spaces into a single type of space.

If you are curious about all the different kind of spaces in Unicode, you might want to read Unicode spaces

Introduction

As the Ghidra open source community is growing, trying to document the new projects around Ghidra. Feel free to fork the gist and propose improvements.

CPU support

New 6502 language module for Ghidra
Atmel AVR helpers for Ghidra - ATmega328p
Processor definitions for DMG and CGB in Ghidra - Gameboy CPU (LR35902) (WiP)
ghidra based disassembly of the x68000's IPL.

Theory

In signal processing, cross-correlation is a measure of similarity of two series as a function of the displacement of one relative to the other.
Manhattan distance
Bhattacharyya distance measures the similarity of two probability distributions.

Libraries

ImageHash which supports average hashing, perception hashing, difference hashing and wavelet hashing.
dhash is a Python library which supports a perceptual hash based on Neal Krawetz’s dHash algorithm in this “Hacker Factor” blog entry.
