Published my first Python package to PyPI

Today I uploaded my first package to [PyPI](https://pypi.org/project/HelloFlask/). It's small a package called HelloFlask!

All this package does, is automate the following tasks:

* sets up a python virtual environment for the user.
* installs Flask, and python-dotenv.
* installs other third party libraries needed by the user.
* Creates a barebones Flask project, by copying some code snippets.

[D] Machine Learning - WAYR (What Are You Reading) - Week 95

This is a place to share machine learning research papers, journals, and articles that you're reading this week. If it relates to what you're researching, by all means elaborate and give us your insight, otherwise it could just be an interesting paper you've read.

Please try to provide some insight from your understanding and please don't post things which are present in wiki.

Preferably you should link the arxiv page (not the PDF, you can easily access the PDF from the summary page but not the other way around) or any other pertinent links.

How to build a simple Hacker News clone using Django 3 - Video

Hi everyone, just released a new video tutorial :-)

Hacker News is a very cool community. It's where all the coolest new things are being shared. Have you ever thought about building your own version of the site?

In this Django tutorial I will show you how to build a simple Hacker News clone using Django 3. I will begin by setting up a virtual environment to work in and then build the project piece by piece.

I hope this sounds like an exciting project to build. You should be able to follow along this video, even if you're a beginner. I try to explain everything I do, but if you have a question or you're stuck, feel free to leave a comment below :-)

YouTube link:
[https://www.youtube.com/watch?v=292GB6snFYo](https://www.youtube.com/watch?v=292GB6snFYo)

Todo list for this video:
\-Create and setup a virtual environment and install Django.
\-Create a new django project and create folders for the base structure
\-Create a django app for the core views and base template for the whole application
\-Make it possible to sign up, login and log out
\-Create a django app for the stories (submissions)
\-Make it possible to submit a story
\-Show the best

[JupyterLab] Bootstrapping work before the spawner starts - change default working directory of terminal

Hello everyone,

We are trying to change the default working directory of users when they start their terminals on JupyterLab. Host machine is a Linux. It looks like this is the option:

#c.Spawner.pre_spawn_hook = None

from subprocess import check_call
def my_hook(spawner):
username = spawner.user.name
check_call(['./examples/bootstrap-script/bootstrap.sh', username])

c.Spawner.pre_spawn_hook = my_hook


Is there any way to append the following line to user's */home/user/.bash_profile* file:

cd /Users/path/toyourstartfolder/

I assume this option can do the trick. Is there any other way to accomplish that?
Thanks.

File storage with a Flask REST Api

Hi Everyone,

I've recently been working on a Flask REST API for a project and I've come to a road block. I'm wondering how I might handle if I wanted to serve files to the user, in this case pdf format. What is a common way to do such a thing, initially I though for example in my SQL table to store the filename extension and then somehow serve the file that way but I was wondering what solutions you would consider best practice? Thanks

[D] RTX 3090, RTX 3080, RTX 3070 Deep Learning Workstation Guide

[Lambda's RTX 3090, 3080, and 3070 Deep Learning Workstation Guide](https://lambdalabs.com/blog/deep-learning-hardware-deep-dive-rtx-30xx/)

**Blower GPU versions are stuck in R & D with thermal issues**

* Lambda is working closely with OEMs, but RTX 3090 and 3080 blowers may not be possible.
* RTX 3070s blowers will likely launch in 1-3 months.

**4x GPUs workstations:**

* *4x RTX 3090/3080* is not practical. Typical home/office circuits will be overloaded. Moreover, there aren't any PSUs that can support this power draw at standard home/office voltages.
* *4x RTX 3070* may require the currently unavailable blower edition.

**3x GPU workstations:**

* *3x RTX 3090:* Will require liquid cooling or PCIe extenders to fit/achieve proper thermals.
* *3x RTX 3080:* Will require liquid cooling or PCIe extenders to achieve proper thermals. A two-slot blower edition may enable a 3x air-cooled workstation without extenders, but it's currently stuck in R & D with overheating problems.
* *3x RTX 3070s:* Will likely work out of the gate, even without blowers -- but leave a PCIe slot empty between cards.

**1x/2x workstations**

* Cooling should be relatively straightforward if you leave proper space between GPUs.

**RTX 30XX performance vs. the RTX 2080 Ti:**

* *RTX 3090 (24 GB):* 1.57x faster for convnets and 1.5x faster for transformers.\*
* *RTX 3080 (10 GB):* 1.4x faster for

Does Beautiful Soup web scraping refresh the page?

I’m web scraping a website that has a live tracking ticker (count of subscribers).

I read somewhere that web scraping refreshes the page which makes the web developers “unhappy”. However, since I’m simply monitoring a css label.... is it still messing up something on the user side? Possibly giving him too much traffic?

Trying to get username for a query in a form.

Hi,

I have the following form which I've made after reading stackoverflow questions.

class PayForm(forms.Form):
def __init__(self, *args, **kwargs):
self.user = kwargs.pop('user',None)
super(PayForm, self).__init__(*args, **kwargs)

print(self.user)

date = forms.DateField()
total = forms.IntegerField()
#company = forms.ModelMultipleChoiceField(Company.objects.filter(employees=self.user))

my issue is I get a name error for self when I uncomment company, the init seems to work but it appears to be called after the variables are set. anyone have a clue what's up with this?

basically what i'm trying to do is this:

I have a model for companies, in that model I have a manytoomany field which can be populated by several usernames, in my form I only want that user to be be able to select companies that contain this user.
