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.

Are there any references on how to create a good design diagram? What do the different colors mean? What do the dashed lines mean?
Sorry if this is a basic question but I don't even know where to start searching for more information. This is the first page I saw that had the diagrams in the format that I've seen before.

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
Small thing, but costed me several hours to find :)

We see a code for contrastive loss, based on a paper. But the labels in this function are reversed from
the paper. Meaning in the paper Y=0 if X1,X2 are from same domain, Y=1 other

Expected Result
Docs page which has migration for 1-2 also has for 2-3 ;
https://github.com/kennethreitz/requests3/blob/master/docs/api.rst
Actual Result
Only 1-2 is still on docs/api.rst, even on repo requests3 (which has no issues only PR's)

Description
if MultinomialNB there is strange behavior of clf.coef_:
clf.coef_ is the same as clf.feature_log_prob_[1]
and
clf.intercept_ is the same as only one clf.class_log_prior_
for example
clf.feature_log_prob_[0][0:3]
array([-3.63942161, -3.17296199, -4.59417863])
clf.feature_log_prob_[1][0:3]
array([-3.51935008, -3.010937 , -6.41836494])
clf.coef_[0][0:3]
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?
It should be clear, from reading the documentation, how to filter out a specific log message that we wish to ignore.
This is specially important for warnings that depend on input, like the one introduced in #4214. Since you seldom have the power to fix the issue that triggers the warning message, caused by the content or behavior of the website you are scraping, you may need to simply ignore th
Current implementation does sequential sigmoid_out and mul_. We can get better performance by fusing this operations together.

face_detection need to scan "known_people" directory every time.
in "known_people" directory I've 20 people and face_detection need a lot of time to "learn" before search known peoples inside new photos (unknown_pictures directory contain 2 photos).

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.

This is for the website repo and there's an equivalent issue at certbot/website#512 but I want to make sure we don't forget this.
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
Listing most popular anti-patterns (without actual implementation) shou

In our job that checks that the code is ok (flake8, mypy...) [1], we want to run all the steps whether any of them fail or not.
This is implemented by using if: true in each step. While this should work, it doesn't. A better way to implement this that probably fixes the issue is to use if: always() instead.
What we should do is:
- Replace all instances of
if: truebyif: alwaysin

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.
