Python

Python is a dynamically typed programming language designed by Guido van Rossum. Much like the programming language Ruby, Python was designed to be easily read by programmers. Because of its large following and many libraries, Python can be implemented and used to do anything from webpages to scientific research.

A description is incomplete. It should mention:
These patterns are not competing, but complementing each other. To achieve availability, one needs both fail-over and replication.

It says in the documentation (the last section - "Working with Virtual Environments"):
For Python 3 add the following lines to the top of your .wsgi file:
activate_this = '/path/to/env/bin/activate_this.py' with open(activate_this) as file_: exec(file_.read(), dict(__file__=activate_this))
However `activate_this.p

We're trying to fix as many broken links as possible before modules move into collections. This is the batch of broken links on some Ansible modules.
NOTE: the link checker sometimes reports an error where a link actually works. Ignore those if you find them.
ISSUE TYPE
- Documentation Report
COMPONENT NAME
It could help potential new contributors if the "How to Contribute" section included the content or a link to the "Good Bug Reports" section of the contributing.md and a link to some simple example tests in step 4
scikit-learn/scikit-learn#16404 adds the Bunch
object to the public API docs. However, the API docs do not reference Bunch
where it's used.
It'd be nice to fix those and link to the now available Bunch
page.
I think "outputs [-1]" and "outputs [0]" are equivalent (reversed) in this line of code, but the former (89%) works better than the latter (86%). Why?
🐛 Bug
To Reproduce
Run following from jupyter lab console
import torch
foo = torch.arange(5)
foo.as_strided((5,), (-1,), storage_offset=4)
Traceback (most recent call last):

We have a few references in the documentation where we use the old name of that OS. We should update them.

The google_travel_time documentation states the following:
By default, the sensor will update the travel time every 5 minutes
and:
For example, if you want to update sensor.morning_commute every 2 minutes on weekday mornings, you can use the following automation...

Update the tutorial for "Building a container from scratch in Go - Liz Rice (Microscaling Systems)"
Description
The instructor in the above mentioned video has created a new version of the same tutorial, which can be found here
Why
It is always good to keep resources and tutorials up-to-date. The new video talks about namespaces, chroot and cgroups, and speaks about containers at a greater depth.
Is this something you're interest

假如有一排房子,共 n 个,每个房子可以被粉刷成红色、蓝色或者绿色这三种颜色中的一种,你需要粉刷所有的房子并且使其相邻的两个房子颜色不能相同。
当然,因为市场上不同颜色油漆的价格不同,所以房子粉刷成不同颜色的花费成本也是不同的。每个房子粉刷成不同颜色的花费是以一个 n x 3 的矩阵来表示的。
例如,costs[0][0] 表示第 0 号房子粉刷成红色的成本花费;costs[1][2] 表示第 1 号房子粉刷成绿色的花费,以此类推。请你计算出粉刷完所有房子最少的花费成本。
注意:
所有花费均为正整数。
示例:
输入: [[17,2,17],[16,16,5],[14,3,19]]
输出: 10
解释: 将 0 号房子粉刷成蓝色,1 号房子粉刷成绿色,2 号房子粉刷成蓝色。
最少花费: 2 + 5 + 3 = 10。

As seen with the test modifications in certbot/certbot#7771, there are lot of individual tests duplicating the same changes to the available modules such adding mod_ssl
before testing a lot of installer functionality or the rewrite_module
before testing redirects.
This code being duplicated makes it harder t
I think listing anti-patterns with some basic reasoning about "why not" is a good idea.
Example - singleton. Although #256 has "won't fix" label
- it is in PRs section, and people (if searching history at all) are searching issues first.
- it was misspelled, Singelton instead of Singleton, therefore impossible to find
Listing most popular anti-patterns (without actual implementation) shou
