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
Is it a known issue (is it even an issue?) that model.test_on_batch returns the sum of losses of each entry in the batch instead of the average? I looked over the changelog and saw no reference to that.
model.train_on_batch does in fact returns the average, but in the docs their return value is documented the same.

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?
This is not an issue related with the code itself but with Scrapy.
I've seen that the only Wikipedias with the Scrapy entry are:
I think it could be a good idea to create this issue
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.
- face_recognition version: 1.2.3
- Python version: 3.7
- Operating System: Debian 10.1
Description
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).
it's possible to cache "learn" anali
Home Assistant release with the issue: 0.103
Integration: Mobile App
Description of problem:
Mobile App registrations don't take a unique ID, making it impossible to de-duplicate registrations. This means that it's easy to end up with duplicate registrations.
We should add a new device_id to the mobile app registration params ([docs](https://developers.home-assistant.io/docs/en
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

One of our packagers asked if we could host our PGP somewhere accessible over HTTPS so they could automatically download it for extra verification on our PyPI packages. I think we can do this.
If this is done, we should document the existence of this file in https://github.com/certbot/certbot/blob/master/certbot/docs/packaging.rst.
数轴上放置了一些筹码,每个筹码的位置存在数组 chips 当中。
你可以对 任何筹码 执行下面两种操作之一(不限操作次数,0 次也可以):
将第 i 个筹码向左或者右移动 2 个单位,代价为 0。
将第 i 个筹码向左或者右移动 1 个单位,代价为 1。
最开始的时候,同一位置上也可能放着两个或者更多的筹码。
返回将所有筹码移动到同一位置(任意位置)上所需要的最小代价。
示例 1:
输入:chips = [1,2,3]
输出:1
解释:第二个筹码移动到位置三的代价是 1,第一个筹码移动到位置三的代价是 0,总代价为 1。
示例 2:
输入:chips = [2,2,2,3,3]
输出:2
解释:第四和第五个筹码移动到位置二的代价都是 1,所以最小总代价为 2。
提示:
1 <= chips.length <= 1
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
Not sure if it was added intentionally, but it's possible to call numpy with the np attribute of the pandas module:
import pandas
x = pandas.np.array([1, 2, 3])While this is not documented, I've seen couple of places suggesting this as a "trick" to avoid importing numpy directly.
I personally find this hacky, and I think should be removed.

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.
