Making a Custom Graph in Jupyter Noteboook

I'm interested in plotting nontraditional logic,math, and networking graphs that don't fall on xy planes or maps. Does anyone know good tutorials for making these nontraditional graphs in Jupyter notebook I would also like them to be interactive?

Old android phone as flask test server

I know this isn't anything new, but I hadn't considered this before so thought I'd share. Flask apps are pretty lightweight so I pulled out an old Pixel 3 XL I had laying around and repurposed it into a flask dev server in no time and doesn't require rooting (unless you want docker). Shouldn't harm anything, but usual disclaimer if you try this on your primary phone.

1. Factory reset phone for good starting base (Optional, recommended if you aren't using it)
1. Also connect to wifi
2. Install termux (from f-droid, not the app store)
1. Download apk: f-droid.org/repo/com.termux_118.apk
2. Allow install from external sources and install
3. Launch termux
3. Set password and update environment
1. passwd
2. pkg update && pkg upgrade
4. Install and run ssh server (dropbear for convenience)
1. pkg install dropbear
2. dropbear
5. Termine IP address and test ssh (should be able to access)
1. ifconfig|grep inet
6. Install python
1. pkg install python
7. Create your flask application, scp it over if needed, and run in termux
1. flask run -h 0.0.0.0 -p 5000
8. You should

Deploy react inside django as a django app on Heroku

I have worked with deploying django and react separately as separate heroku apps and integrate them. But I don't know how to deploy a structure where the reactapp is inside Django's project directory disguised as a django app. How do you run the npm build on Heroku? I couldn't find any tutorials that does this, can someone help me out here? thanks!

nbsnapshot - Automated Jupyter Notebook Testing

​

Hi all!

I want to share a project I've been working on to facilitate Jupyter notebook testing!

When analyzing data in a Jupyter notebook, I unconsciously memorize "rules of thumb" to determine if my results are correct. For example, I might print some summary statistics and become skeptical of some outputs if they deviate too much from what I've seen historically. For more complex analysis, I often create diagnostic plots (e.g., a histogram) and check them whenever new data arrives.

Since I constantly repeat the same process, I figured I'd code a small library to streamline this process. nbsnapshot benchmarks cell's outputs with historical results and raises an error if the output deviates from an expected range (by default, 3 standard deviations from the mean). You can see an example in the image accompanying this post.

To learn more, check out the blog post.

I'd love to hear what you think!

Incoporating lens(df) value into groupby() function

Task 5b: Calculate percentage of people with work experience that are offered a job, the percentage of people with work experience not offered a job, the people with no work experience offered a job and the percentage of people with no work experience not offered a job.

output

Publishing charts on the web with Panel - is HvPlot relevant?

I switched a while back from Matplotlib and Seaborg to Plotly - since it's interactive and just IMHO looks better. I've been looking to implement some of my figures on my website. There is a simple way to simply export to HTML from Jupyter, but I see two limitations with this:

1) The code is very long, and sometimes crashes my browser when just pasting the code for a single figure

2) As I understand it there are limitations to the interactivity with this approach.

Due to this, I've been looking into Panel and HvPlot. There are so many modules mentioned around the docs though that I can hardly see what is relevant to my use case. It seems Plotly can be implemented directly in Panel so I'm not sure if HvPlot should be used as a medium between Plotly and Panel to enable more functions or rather as an alternative to Plotly.

If anyone has experience setting up widgets and similar, I'd be very interested in some tips here!

Plotting 3D vectors with autosized coordinate axis

I often need to visualize 3D vectors for statics problems in Jupyter Lab for which i currently use the following code using matplotlib quiver. I currently normalize the vectors to keep them within the area, but that's a huge limitation.

I'd like to have the colored coordinate axis (x,y,z) shown all the time, and have the axis scale with the plot area automatically, depending on the position and size of the plotted vectors. The plot would show the actual magnitude and direction of the vector. Can anyone help me out?

The following code produces the plot:
[Plot](https://i.stack.imgur.com/1kz8n.png)

import matplotlib.pyplot as plt
%matplotlib ipympl

# vector data. not important
roa_vek=Matrix([0,0,12])
rob_vek=Matrix([4,12,0])
rab_vek=rob_vek-roa_vek
f=2000
fab_vek=f*rab_vek/rab_vek.norm()
mo=roa_vek.cross(fab_vek)

ax=plt.figure().add_subplot(projection='3d')

# if i dont set these, the plot is all zoomed in
ax.set_xlim([-1,1])
ax.set_ylim([-1,1])
ax.set_zlim([-1,1])

ax.set_xlabel("X")
ax.set_ylabel("Y")
ax.set_zlabel("Z")
origo=[0,0,0]
ax.view_init(30, 45)
