  jsonSerialize() in extended class

Since PHP 5.4.0, there is a convenient interface JsonSerializable which can be used to indicate that a PHP object can be serialized to JSON object. It has only one method which should be implemented by any class which implements this interface. The method is named jsonSerialize(). It's really easy to serialize an object to JSON object. Here is one example: <?php class ArrayValue implements JsonSerializable { public function __construct(array $array) { $this->array = $array; ...

  How to handle ES6 modules in NodeJS

In modern JavaScript, there are two types of modules: ES6 module and CommonJS module used by NodeJS. These two types of module are not compatible. Many people would wonder how to load ES6 modules in their NodeJS project. This post will show how this can be done. Difference The syntax of the module being loaded is different.

  Accessing Reddit top posts using OAuth

Previously one can use the https://www.reddit.com/r/rprogramming/top.json API to access one subreddit's top posts. This API doesn't require any access token to fetch the data. However, this API may not work all the time. Reddit may block the API's request if it finds that you are using a script or some app which accesses the API now and then. For an app or script which needs to fetch the data routinely, what should we do? Reddit provides one method which can be used to fetch this kind of to...

  Use pdb to help understand python program

  As I have mentioned in Why do I need a debugger?: (3) Debugger is a good tool to help you understand code. So when I come across difficulty to understand vfscount.py code in bcc project, I know it is time to resort to pdb, python's debugger, to help me. The thing which confuses me is here: counts = b.get_table("counts") for k, v in sorted(counts.items(), key=lambda counts: counts[1].value): print("%-16x %-26s %8d" % (k.ip, b.ksym(k.ip), v.val...

  Where Have You Installed Your Python Packages?

Preface I am writing this article because I recently noticed in the Python community that there are several frequently asked questions: Why does running the command after installing pip result in a "executable not found" error? Why does importing a module result in a "ModuleNotFound" error? Why can I run my code in PyCharm, but it doesn't work in the command prompt? Rather than just providing solutions, it is better to teach people how to fish. To address these types of issues, you need to und...
