Use fast data algorithms (2021)
I'm late on the reply but I was using xxhash for something similar, but found that Meow hash was faster for me. Feel free to benchmark, since I'm sure it could vary depending on CPU architecture.

Cryptanalysis of Meow Hash
for everyone who doesn't think highly of Casey Muratori (or at least the way he conducts himself online), the author of Meow Hash, took the criticism quite graciously:

Reading a file in parallel
Is a standardized hashing algorithm required? SHA256 takes several CPU cycle per byte, but there are several hashing algorithm utilizing AES-NI that gives them 15-16 bytes per cycles, which translates to tens of gigabytes per second on modern CPU. At least one of them has been ported to .NET Core, and from what I see properly calls AES primitives.

76% Faster CPython
MeowHash is the fastest non-cryptographic hash available online, and if it were used in CPython, which performs a hash for every fundamental operation in the language, then Python would be much faster.

Bitcoin Sentiment Analysis using Python and X (Formerly Twitter)
Thankfully, Python, the go-to coding language for loads of developers, is here to save the day. It's got some awesome features for diving into text sentiment analysis. With cool libraries like Tweepy, we can sift through X(Twitter) data and snag those interesting tweets about Bitcoin. And then there's TextBlob, a clever tool for understanding the sentiment in text. When it's time to clean up and organize all that data, libraries like pandas and numpy are there to help out. And let's not forget about matplotlib, the master of visualisations that can help us see the trends in sentiment crystal clear. Armed with these tools, developers can really dig deep into social media data and figure out what the general public thinks about Bitcoin.

PEP 744 – JIT Compilation
> It provides a meaningful performance improvement for at least one popular platform (realistically, on the order of 5%).
At first it will not provide a large boost, but it will set the foundations for larger gains in subsequent releases. They link a list of some proposed improvements already underway, with improvement estimates, at https://github.com/python/cpython/issues/115802

Featured Mod of the Month: Phil Ashby
After that, with the basics of software engineering understood, I would move on to a wider use language, with a bigger ecosystem to employ, most likely Python. This would expose me to large system design / distributed systems and architectural challenges...
