.. NOTE from the future: Whoops, this was written and forgot in the depths of my drafts. So I just reviewed it and said, hey, It is acceptable to post :-D .. The third (and probably last) post about this lovely Jenkins guy. It seems that people is right, lately I'm Jenkins man. Most of…

Kernel Methods in Machine Learning with Python Image by Editor | Midjourney ## Introduction Kernel methods are a powerful class of machine learning algorithm that allow us to perform complex, non-linear transformations of data without explicitly computing the transformed feature space. These methods are particularly useful when dealing with high-dimensional data or when the relationship between features is non-linear. Kernel methods rely on the concept of a kernel function, which computes the dot produc

# Python Types and C-Structures Several new types are defined in the C-code. Most of these are accessible from Python, but a few are not exposed due to their limited use. Every new Python type has an associated PyObject * with an internal structure that includes a pointer to a “method table” that defines how the new object behaves in Python. When you receive a Python object into C code, you always get a pointer to a PyObject structure. Because a PyObject structure is very generic and defines only

# Logging Cookbook ¶ Author: Vinay Sajip <vinay_sajip at red-dove dot com> This page contains a number of recipes related to logging, which have been found useful in the past. ## Using logging in multiple modules ¶ Multiple calls to logging.getLogger('someLogger') return a reference to the same logger object. This is true not only within the same module, but also across modules as long as it is in the same Python interpreter process. It is true for references to the same object; additionally, applicatio

每学习一门语言，就总会想找到它的 `core`。对于Python，我认为是它的 `core` 是字典。无论从 `CPython` 实现上或者是平时使用时的类机制，都能体会到Python中字典的作用。但是这篇文章不是什么教程或者学习体会。只是一些杂言。TL;DR...

Python has a function called sys.getrefcount() that tells you the reference count of an object. For example, the following code,import sysprint sys.getrefco
