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.

In the solution for the pastebin/bitly system design, the write to cache flow is missing in the second diagram which refers to the scaling aspect. The cache has only a read arrow but not a write arrow. The diagram will be more intuitive if a write-through/write-back cache mechanism was indicated.

There are some interesting algorithms in simulation from Physics, Chemistry, and Engineering especially regarding Monte Carlo simulation: Heat Bath algorithm, Metro-Police algorithm, Markov Chain Monte Carlo, etc.
Huge and nice collection and also getting very much appreciated from the community.
It would be great if somebody can translate into English then it will be reaching out to global.
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
As indicated in the FAQ, the way to import ResNeXt101 is from keras.applications.resnext import ResNeXt101. But in the latest Keras 2.3.1 and Keras-Applications 1.0.8, it gives ImportError: No module named 'keras.applications.resnext'. I try to change it to `from keras_applications.resnext import preproces

Description
Using dbscan with precomputed neighbors gives an error in 0.22.X, but not in 0.21.3.
I am not sure if this is an intended change or not, but could not see anything on this in the release history. If this is due to a mistake on my part on how to us precomputed neighbors, please tell me, and I will direct my question elsewhere.
Steps/Code to Reproduce
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?
See scrapy/scrapy#3991 (comment)
In the parts of the documentation where we currently cover Request.from_curl we may want to mention this online tool as well.
Context
We would like to add torch::nn::functional::normalize to the C++ API, so that C++ users can easily find the equivalent of Python API torch.nn.functional.normalize.
Steps
- Add
torch::nn::NormalizeOptionstotorch/csrc/api/include/torch/nn/options/normalization.h(add this file if it doesn’t exist), which should include the following parameters (based on https://pytorch.

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.

Currently Robie Basak who did most of the work in creating the Certbot snap has control of it. Once we're ready to start pushing/deploying it ourselves, we should take over control from him.
给定两个由小写字母构成的字符串 A 和 B ,只要我们可以通过交换 A 中的两个字母得到与 B 相等的结果,就返回 true ;否则返回 false 。
示例 1:
输入: A = "ab", B = "ba"
输出: true
示例 2:
输入: A = "ab", B = "ab"
输出: false
示例 3:
输入: A = "aa", B = "aa"
输出: true
示例 4:
输入: A = "aaaaaaabc", B = "aaaaaaacb"
输出: true
示例 5:
输入: A = "", B = "aa"
输出: false
提示:
0 <= A.length <= 20000
0 <= B.length <= 20000
A 和 B 仅由小写字母构成。

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

Can be moved to the code style guide in the documentation: https://dev.pandas.io/docs/development/code_style.html
This way we can remove the page from the wiki, that is mostly outdated.

I was having a very hard time figuring out
fill = A.stack().mean()
A.add(B, fill_value=fill)fill = 4.5. However I computed a value of 3.2 because I was taking the mean from the column of A not the DataFrame A.
This coming after the Indexing chapter where "explicit is better than implicit." I was thinking that this should be a little more explicit.

Description of issue (what needs changing):
The text says "First we'll make sure that we're using Python 2, and then go ahead and install and import the stuff we need." but the code below indicates we need to use Python 3.
