Matplotlib Scatterplots, but with Emojis as Markers

I wrote a function to create scatterplots using emojis as markers to support some analysis & visualization I'm doing for a (very silly) side project. After a good bit of research (I was pretty shocked this didn't exist already), I built this based on [this article](https://towardsdatascience.com/how-i-got-matplotlib-to-plot-apple-color-emojis-c983767b39e0), but adapted to produce a scatterplot instead of a bar chart.

#function to create a scatterplot with emojis as markers
#based on https://towardsdatascience.com/how-i-got-matplotlib-to-plot-apple-color-emojis-c983767b39e0
#follow instructions above to install & build mplcairo

#Set the backend to use mplcairo
import matplotlib, mplcairo
print('Default backend: ' + matplotlib.get_backend())
matplotlib.use("module://mplcairo.macosx")
print('Backend is now ' + matplotlib.get_backend())

# IMPORTANT: Import these libraries only AFTER setting the backend
import matplotlib.pyplot as plt, numpy as np
from matplotlib.font_manager import FontProperties

# Load Apple Color Emoji font
prop = FontProperties(fname='/System/Library/Fonts/Apple Color Emoji.ttc')

# Load Apple Color Emoji font

Passing variable from form into url

I have a flask app which provides certain information based on a public key. It also allows editing of the information for those with the matching private key.

@main.route('/thing/<unique_key>/')
@main.route('/thing/<unique_key>/secret/<secret_key>')
def view_thing(unique_key, secret_key = None):
if secret_key == None:
# render public information page through jinja

if secret_key == the_right_secret_key_I_pull_from_the_database:
# render private information page allowing editing through jinja

These routes all work fine and as expected.

I would like to include a form on the public information page which allows users with a private key to enter it and redirect to the private page (eg "Are you the owner of this information? Enter your private key and click submit to edit")

I know how I can pass the contents of a form to a flask POST method, but I don't want to do that here. How do I get it to instead take the input of the text box and redirect to the

[Beginner] Request for Django workflow suggestions

Hi all,

I'm currently learning Django and programming in general. I've managed to build a website, deploy it to a linux server, and use GCP for my static files. However, I'm not satisfied with my workflow.

I pushed to PROD using scp via the CLI. Then I continued to develop directly in PROD. This feels like a very bad way to continue.

How do development and deployment using GIT work in the context of webdev and Django? Develop locally, push to GIT and clone after logging on the server via ssh? Or do people use Docker to deploy to linux servers?

I would appreciate your advice and tips on how I can learn best-practices from the start. Thanks.

I'm giving back - here's a free book on Python - keep learning during the pandemic!

I started writing "[Slither into Python](https://www.slitherintopython.com/)" a little over a year ago and I have recently completed it. I decided to release it online for free as a thank you to the programming community, in particular the Python community. I know a lot of you out there are learning Python at the moment and I hope this resource can serve you well.

If you have any questions, or feedback for me, then please let me know, my email is on the site!

I know this is a difficult time for many of us but we can use it to our advantage! Many of us have a lot more free time now then we ever had before, so use this time to continue learning and really ramp up your skills!

Providing comments on code is a pain, so I built codecomments.dev

In here and r/learnpython there are frequently requests to look at others' projects and provide any comments.

It's actually kind of a pain to provide these comments. You can try to write comments back directly in reddit (eg your loop on line 27 sucks) or if you \*really\* care enough then you can clone the repo and edit it and then do a pull request back. But that's a lot of work.

There's obviously a ton of enterprise grade options for doing CI/CD and code reviews, etc - but they're a bit above my paygrade.

So I built [https://codecomments.dev/](https://codecomments.dev/) (in python, obv). Free, obv.

Paste in the url of a script on github and it will load it, display it with pretty code formatting and allow you to add comments on individual lines. The input accepts markdown so you can even include code or links in your comment. I built this for python but it displays proper formatting for most languages.

You can then share it back to the community or the person who asked for the review with a simple URL with a human-readable name. Have a look at [https://codecomments.dev/view\_script/uncovered-ammonite/](https://codecomments.dev/view_script/uncovered-ammonite/) as an example.

A New Interesting Framework

Are you interested in ethical hacking ?? If yes . would not it be great if the framework is in \*\*python\*\* . with over 18 payload in python . and flexable enough to help you **generate your own payload in python** . and **no need for using hard syntax for passing arguments to the generator** . because it works with menus . works on different platforms .

[ZKit-Framework](https://github.com/000Zer000/ZKit-Framework) is the framework Im talking about . because of some problems i cant include a picture of it working . **but please use it legally and Have Fun** !

[D] How do ML researchers make progress when iteration cost is prohibitively high? (GPT3, Image-GPT, Autopilot, RL, etc.)

Today Andrej Karpathy released code for a minimal gpt implementation ([here](https://github.com/karpathy/minGPT)), but what I found most interesting was his notes on the implementations. In particular at the end of the README he noted from the GPT-3 paper:
> GPT-3: 96 layers, 96 heads, with d_model of 12,288 (175B parameters).

> GPT-1-like: 12 layers, 12 heads, d_model 768 (125M)

> We use the same model and architecture as GPT-2, including the modified initialization, pre-normalization, and reversible tokenization described therein

> we use alternating dense and locally banded sparse attention patterns in the layers of the transformer, similar to the Sparse Transformer

> we always have the feedforward layer four times the size of the bottleneck layer, dff = 4 ∗ dmodel

> all models use a context window of nctx = 2048 tokens.

> Adam with β1 = 0.9, β2 = 0.95, and eps = 10−8

> All models use weight decay of 0.1 to provide a small amount of regularization. (NOTE: GPT-1 used 0.01 I believe, see above)

> clip the global norm of the gradient at 1.0

> Linear LR warmup over the first 375 million tokens. Then use cosine decay for learning rate down to 10% of its value, over 260 billion tokens.

> gradually increase the batch size

django-scan-fields update: Now generate frontend forms based on your django models

Hi guys!

A few months ago I created [Django scan models](https://github.com/jessielaf/django-scan-models). I also posted a [post](https://www.reddit.com/r/django/comments/fob7om/djangoscanmodels_parse_django_models_to_frontend/) about this to this subreddit. Now I have come with an update! Called [vue-scan-field](https://github.com/jessielaf/vue-scan-field).

This package can create input fields in Vue based on the code generated by Django scan models! This means that your frontend validation and forms are up to date all the time!

It currently only works with Vuetify as UI framework and vee-validate as validator. But if there are requests I can look to integrate other frameworks.
