Twint is an advanced Twitter scraping tool written in Python that allows for scraping Tweets from Twitter profiles without using Twitter's API.

Twint utilizes Twitter's search operators to let you scrape Tweets from specific users, scrape Tweets relating to certain topics, hashtags & trends, or sort out sensitive information from Tweets like e-mail and phone numbers. I find this very useful, and you can get really creative with it too.

Primer on Python Decorators.

In this tutorial on decorators, we’ll look at what they are and how to create and use them. Decorators provide a simple syntax for calling higher-order functions.

By definition, a decorator is a function that takes another function and extends the behavior of the latter function without explicitly modifying it.

Haskell Style Guide.

This document is a collection of best-practices inspired by commercial and free open source Haskell libraries and applications.

Style guide goals:

The purpose of this document is to help developers and people working on Haskell code-bases to have a smoother experience while dealing with code in different situations. This style guide aims to increase productivity by defining the following goals:
- Make code easier to understand: ideas for solutions should not be hidden behind complex and obscure code.
- Make code easier to read: code arrangement should be immediately apparent after looking at the existing code. Names of functions & variables should be transparent and obvious.
- Make code easier to write: developers should think about code formatting rules as little as possible.
- Make code easier to maintain: this style guide aims to reduce the burden of maintaining packages using version control systems unless this conflicts with the previous points

PostgreSQL 13 Released!

The PostgreSQL Global Development Group today announced the release of PostgreSQL 13, the latest version of the world’s most advanced open source database.

PostgreSQL 13 includes significant improvements to its indexing and lookup system that benefit large databases, including space savings and performance gains for indexes, faster response times for queries that use aggregates or partitions, better query planning when using enhanced statistics, and more.

Along with highly requested features like parallelized vacuuming and incremental sorting, PostgreSQL 13 provides a better data management experience for workloads big and small, with optimizations for daily administration, more conveniences for application developers, and security enhancements.

Datalevin is a simple durable Datalog database.

The rationale is to have a simple, fast and free Datalog query engine running on durable storage. It is our observation that many developers prefer the flavor of Datalog popularized by Datomic® over any flavor of SQL, once they get to use it. Perhaps it is because Datalog is more declarative and composable than SQL, e.g. the automatic implicit joins seem to be its killer feature.

Rustler is a library for writing Erlang NIFs in safe Rust code. That means there should be no ways to crash the BEAM (Erlang VM). The library provides facilities for generating the boilerplate for interacting with the BEAM, handles encoding and decoding of Erlang terms, and catches rust panics before they unwind into C.

The library provides functionality for both Erlang and Elixir, however Elixir is favored as of now.
