With the recent hype around ChatGPT, GPT-4, and large language models in general, communities like Hacker News are breaking out into a this time it’s different doom and gloom.
macOS Catalina introduced zsh as the default interactive shell. zsh is compatible with Bourne shell (sh) to a large degree and introduces many valuable extensions that make everyday productivity more pleasant. In this post, I list some shortcuts for the zsh line editor (also known as the command prompt) in its default configuration.
If you’re like me, you love npm ci. A lot. Until that one fateful day.
Given a number of strings that contains random ASCII characters, find all strings, that contain the same amount of ‘A’ and ‘B’ characters.
Learning a language is different when learned as a native language or as a foreign language. We will illustrate this by taking a look at how Japanese as a foreign language (JFL) learners and Japanese as a native language (JNL) speakers learn about Japanese grammar.
For the past month I’ve been using the J programming language to solve Project Euler puzzles. The language makes many of the tasks that one would usually spend quite some time on, especially with multidimensional arrays, quite pleasant to work on.
I’ve taken some time to enhance my blog with two useful features:
I will cover how the two have been implemented.
On April 15 2018, I moved to Tokyo, Japan. I suppose that changed a few things in my life.

As time goes on, smart contract requirements change. Often, a feature is added or a bug is found. But, once a smart contract has been deployed on the blockchain, it can’t be upgraded. The entire value proposition of a blockchain is immutability. Yet, in the real world, contracts change all the time. For example, a labor contract will change when new labor laws are introduced.

When building your smart contract platform — whether on Ethereum or any other blockchain — at some you’ll be faced with the question of ownership. In this article, I will explain three different types of smart contract ownership and discuss their advantages and disadvantages.
Have you ever wondered how your users can spend
ERC20 platform
