In the first part of this series tutorial, we learned how to build a weather app using Django, a powerful Python framework for building web applications. Although not a prerequisite to understanding this second part, learning how to design such an application is worth your time. For the very first time, I will be explaining … Read more
I recently started a new website and to rank up in the search engines I hired an SEO expert. He suggested several activities out of which one was building lots of backlinks. We agreed on the budget and the timeframe in which he delivers 200 links in a month. These links are a mix of … Read more
Playing with any large language model (LLM), such as GPT-4, is fascinating. But it doesn’t give you an accurate understanding of where AGI is heading because one isolated snapshot provides limited information. You can gain more insight into the growth and dynamicity of LLMs by comparing two subsequent snapshots. Roughly speaking, it’s less interesting to … Read more
In this article, we’ll learn about function constructors, a Solidity language feature enabling us to execute a function during smart contract creation. It’s part of our long-standing tradition to make this (and other) articles a faithful companion or a supplement to the official Solidity documentation. We’ll base this article on the original Solidity programming language … Read more
In this article, we’ll learn about function overloading 🎛️🔁👷♂️💻🚀, a useful and interesting feature in the Solidity programming language. It’s part of our long-standing tradition to make this (and other) articles a faithful companion or a supplement to the official Solidity documentation. We’ll base this article on the original Solidity programming language content. Overview Function … Read more
In this article, we will focus on the second topic of the interesting pair, the fallback function, as a follow-up on the receive ether function discussed in the previous article. It’s part of our long-standing tradition to make this (and other) articles a faithful companion, or a supplement to the official Solidity documentation. Overview The … Read more
In this article, we will focus on an important topic, the receive Ether function in Solidity. This function allows us to receive the currency and is the first of the two possible approaches for receiving currency.

Solidity has many useful features that enable us, smart contract developers, to make safe, secure, and functional smart contracts. We have discussed other interesting Solidity features, and this time, we’ll focus on one very important feature of Solidity called function visibility. It determines who can call a function and who can access its variables. In … Read more
In this article, I will cover accessing multiple matches of a regex group in Python. 💡 Regular expressions (regex) are a powerful tool for text processing and pattern matching, making it easier to work with strings. When working with regular expressions in Python, we often need to access multiple matches of a single regex group. … Read more
No, ChatGPT really doesn’t help with this (yet…) 🙂 but it did help me write the code snippet explanation (which I attached after each code output). In my example, we will take a special route in Budapest, using one of the easiest to use library, gmplot. We can create our maps directly in HTML code … Read more
