  Python internals: how callables work

[The Python version described in this article is 3.x, more specifically - the 3.3 alpha release of CPython.] The concept of a callable is fundamental in Python. When thinking about what can be "called", the immediately obvious answer is functions. Whether it’s user defined functions (written by you), or builtin functions (most probably implemented in C inside the CPython interpreter), functions were meant to be called, right? Well, there are also methods, but they’re not very ...

  Examples of bad design

Good designs always help users solve their problems in a convenient and familiar way. It takes little or no time for users getting used to the product with a good design. In contrast, bad designs frequently introduce confusion and complexity to users. Before we design any product, we should think carefully about every aspect of the product. We share some really bad design here to show how they can affect people's life. 1. USB Connector Have you ever put one in right on the first try? We frequen...

  Illiterate Programming

Donald Knuth cleverly imprisoned the phrase "Literate Programming" - if you're not documenting your source with his particular methodology then you must be a proponent of "Illiterate Programming," which sounds truly awful. I very much believe in documented code but I think no amount of pontification in English will ever make a piece of code clearer than the code itself (I'm not talking about project or API documentation). I'm also not talking about the super...

  When and Where to Use Pointers in Go

When declaring variables in Go, we usually have two syntax options: In some scenarios, pointers; in others, reference; sometimes, either. It’s great to have choices, but it is also confusing sometimes as to which one in which scenario. To be more reasonable in choice-making, I started from pointers, walked through their natures, and summarized some rules in using them in Go. from unsplash, Jordan Ladikos Pointers Go has pointers. A pointer holds the memory address of a ...
