My code for Tic-Tac-Toe (beginner), compared to my mate that works at google's code.

Thought it would be interesting seeing someone beginner code, vs someone's professional code on the same project. After I sent him my code he replied with how he would have done it, as a comparison.

Which platform to quickly build a (paid) python-based API

Hi!

I have a python algorithm and I want to make a scalable web interface / API for that algorithm.

**First I would like to enable people to make call to my algorithm, either on the web interface or through a web api.**

- Which platform would be the best for me ? AWS lambda ? google app engine ? pythonanywhere ? something else ?

**Then if it works well I would like to create billing plans such as "ipinfo.io" (like 20 euros per month for X calls / X CPU time used...)**

- I know how to code in python / php but I don't see myself building the whole used authentification / billing plans.. payment tracking. Is there an easy platform to set up paid apis ?

Finally.. i'm poor so I can't afford to spend too much. I've seen 3scale for example but 750 euros is too much, especially considering that my algorithm is quite simple (like just a function with some arguments processed by a single python function, which gives back one or multiple numbers..).

Thanks!

Django app that returns value based on what users choose in form (x-post r/django)

I did the tutorial on the Django website and made the polls app. I've since added static pages and gained a better understanding of how URLs and views work.
I've written a Python function that is essentially a logistic regression predictor. It takes in an array and based on that array returns a value.
I want to build off the polls app in Django, and make it so that instead of typing in an array, users can select from the poll form, and then the web app returns the value.
How would I go about starting this?

Is this no longer the place to post notifications about Python library updates?

Lately, when I post notices about a new release of one of my Python libraries here, the post is pretty reliably downvoted. If people really don't care about the libraries I'm putting out, that's fine, but I just wanted to make sure I'm not violating a rule of some kind.

[HELP] Left Join between multiple databases

I want to do a left join with another db, What would be the django equivalent of this query ?

USE PARTNER_DB;
SELECT CLIENT_ID, PARTNER.FIRST_NAME, PARTNER.LAST_NAME,
RPM, DRAWDOWN_PROTECTION, CONCAT(EMPLOYEE_DB.EMPLOYEE.FIRST_NAME, " ", EMPLOYEE_DB.EMPLOYEE.LAST_NAME),
EMPLOYEE_DB.EMPLOYEE.MAIL
FROM PARTNER
LEFT JOIN EMPLOYEE_DB.EMPLOYEE
ON RM_ID = EMPLOYEE_DB.EMPLOYEE.EMP_ID
WHERE CLIENT_ID = 'X1234'


I am using multiple databases in my project and both of these databases are not managed by django.

I tried to dig into django documentation but was unable to find a way to achieve this, instead i bumped into this
[https://docs.djangoproject.com/en/1.11/topics/db/multi-db/#no-cross-database-relations][1].

I am sure that there will be a hack / workaround this. Looking forward to your solutions.

Clustering multiple GPUs from different machines and remotely run Jupyter Notebook

Hello everyone, I am a newcomer here in this community.
I have only 2 GB GPU but my friend has 4GB so I generally train my model on his machine. I normally use Jupyter Notebook and I code in Python. Recently I came to know about "Running a notebook server" and I set up that. Now I can remotely run a jupyter notebook on my machine (client) while the resources are used from my friend's machine (server).

4 GB of GPU is also not sufficient for me. I am curious if I could remotely use GPUs from many of my friends' machine and cluster them and then remotely run the jupyter notebook. Its similar to the server-client model that we previously created but I wish to extend it to multiple "shared-servers" so that I can use all of their GPU's in collaborative and distributive fashion. It is a kind of 'many-to-one' server (many) and client (one) model.

Can anybody help me how can I achieve that in Jupyter Notebook server ?
Or is there any option to remotely use GPU from different machines and run my python code remotely ?

Thanks

I have set up my React frontend. Need a backend to manage user accounts and store data - is Django a good progression?

As mentioned in the title, I have set up the base foundation for my webapp using React/Redux for my front end.

I would like to take it a step further by adding a backend so that users can create accounts, login, and save data.

I have been looking into Firebase as it's recommended but it feels like I won't learn as much about backend / databases since Firebase does a lot of it behinds the scene.

I am considering Django and was wondering if this would be a good progression for me? Where does Django or Firebase fit into the picture?

I have zero experience with anything backend related but want to learn more.

Are Django session variables secure?

I am creating an app for use in our organization that will login users based on their Office 365 credentials using OAuth2.0. I am looking at fetching an access token that I will store in a session variable. Right now, though, I am just saving 'oauth_state' into a session variable and setting that variable to 'authorized'. Upon loading of each (non-login view), I am checking whether 'oauth_state' is set to 'authorized'. I'm probably going to change this and store a token the variable and use that to query the MSGraph API for a 200 response upon each page load. Anyways, here is an example of what I am doing:

@never_cache
def authorization(request):
microsoft = OAuth2Session(client_id,scope=scope,redirect_uri=redirect_uri)
token = ""
try:
users = 'https://graph.microsoft.com/v1.0/me' ##msgraph query url-
##This query is purelyjust used to
##authenticate user!
token = microsoft.fetch_token(token_url,client_secret=client_secret,code=request.GET.get('code', '')) ##Code is the authorization code present
##in request URL
header = {'Authorization': 'Bearer ' + token['access_token']}
response = requests.get(url = users, headers = header)

if int(response.status_code) != 200: ##if status code is not 200, then authentication failed. Redirect to login.
print ('Not validated. Return to login.')
request.session.flush()
return redirect('http://localhost:8000/login')
except Exception as e:
print ('User not does not have authentication rights')
request.session.flush()
return redirect('http://localhost:8000/login')

request.session['oauth_state'] = 'authorized'
response = HttpResponseRedirect('http://localhost:8000/search')
return response

I am then using this to check if 'oauth_state' is set to 'authorized'. However, I may change this so that the token is used to query the MS Graph API in each function in order to check if the user has proper permissions or not. Here's an example of what I am doing:

def search(request):
try:
if (str(request.session['oauth_state']) != 'authorized'):
print ('Not authorized')
request.session.flush()
return redirect('http://localhost:8000/login')
except Exception as e:
print ('Not authorized')
request.session.flush()
return redirect('http://localhost:8000/login')
<rest of code>

How insecure is this? Should I possibly be passing in the token to the response header? Or should I get rid of this method, and use django's standard auth and login system? I really appreciated the benefits of OAuth2.0, but if this method compromises our security, I might scrap it.
