GSoC'22: Personal Recommendation of a track

See this blog at MetaBrainz Blogs

Hi Everyone!

I am Shatabarto Bhattacharya (also known as riksucks on IRC and hrik2001 on Github). I am an undergraduate student pursuing Information Technology from UIET, Panjab University, Chandigarh, India. This year I participated in Google Summer of Code under MetaBrainz and worked on implementing a feature to send personal recommendation of a track to multiple followers, along with a write up. My mentors for this project were Kartik Ohri (lucifer on IRC) and Nicolas Pelletier (monkey on IRC)

Proposal

For readers, who are not acquianted with ListenBrainz, it is a website where you can integrate multiple listening services and view and manage all your listens at a unified platform. One can not only peruse their own listening habits but also find other interesting listeners and interact with them. Moreover, one can even

	import requests
	from pprint import pprint
	import matplotlib.pyplot as plt
	import math
	import numpy as np
	from typing import List, Tuple, Optional

	def get_orderbook_data(symbol, api="https://api.hyperliquid.xyz/info", nsig_figs=2):
	print(f"{symbol} orderbook data")
	response = requests.post("https://api.hyperliquid.xyz/info", json={"type": "l2Book", "coin": symbol, "nSigFigs": nsig_figs, "mantissa": None})
