Just an area where I put things I learned
In AWS Lambda, soemtimes I get "Unable to import module 'lambda_function': No module named 'xpress'" error message. This is just because the default Lambda doesn't have the dependency required.
I needed pandas and numpy. I used this tutorial to get me through it. https://www.youtube.com/watch?v=1UDEp90S9h8
Now I need to have xpress installed. I am looking up "Python xpress wheel files" and will upload it as a layer to my function (just like we did with pandas in youtube video above).

ssh -p 922 ${username}@linux.cs.wwu.edu to ssh into school machines
scp -P 922 ${username}@linux.cs.wwu.edu:~/document.txt ~/Documents/ to copy files from my VM to my personal Documents directory on my local machine.
For my sake, grabbing LaTeX files I use scp -P 922 rosej25@linux.cs.wwu.edu:/projects/49x/tex2speech/texFiles/computer.tex ~/Documents/ command
This is for me to get to my tex2speech logs scp -P 922 rosej25@linux.cs.wwu.edu:~/CSCI/Tex2Speech/latex2speech/tex2speech/log.log ~/Documents/
After creating a virtual environment, and having my requirements in requirements.txt. My folder structure should look something similiar:
project/ venv app.py requirements.txt
If you run python3 app.py it should run locally
Before proceding, make sure you have the AWS CLI pip3 install awscli then download the elastic beanstalk CLI pip3 install awsebcli If you type aws in the terminal you can see the AWS CLI was downloaded successfully, along if you type eb in the terminal you can see that that was downloaded successfully too.
In the command line, to create an elastic beanstalk application run eb init -p python-3.6 projectName --region us-east-1
Now to setup the configuration type eb init which will prompt you to add a keypair so that you can connect to your EC2 instance through SSH. If you ever need to change this information in the future run eb init -i
Create an environment and deploy the application with eb create flask-env command, this could take about 5 minutes to create all the resources.
To open your application run eb open
If you ever need to completely delete everything on elastic beanstalk run eb terminate flask-env
if you ever need to redeploy your code to the same application run eb deploy in the repository
An easier virtual environment to use is pipenv
To create a shell
pipenv shell
To download dependencies in PipFile (similiar to requirements.txt)
pipenv install
Sometimes when running pipenv shell it doesn't know where Python3.6 is. To find this, type python or python3 in terminal
- Type
import systhen enter - Type
print(sys.executable)to get the path. Copy the path and get out of python interpreter
In regular terminal type pipenv --python <path_to_python>
To setup a temporary virtual environment the following commands are
python3 -m venv envsource env/bin/activate
This creates a env/ folder so in .gitignore be sure to add env/
After creating the environment, if you want to add installed libraries to the requirements.txt file run the following command
python3 -m pip freeze > requirements.txt
To download all items in your requirements.txt file run the following command
pip install -r requirements.txt
To create a Next.JS project write this command in your terminal npx create-next-app nextjs-blog --use-npm --example "https://github.com/vercel/next-learn-starter/tree/master/learn-starter" for a basic layout. You need to have node.js installed
To create your own server in the directory you use the command python3 -m http.server you can then access this server on your local laptop by going to localhost:8000.
To access this on a phone or another computer that is on the same network, you would get your IP address, and in a browser would be <IPAddress>:8000 where the port is 8000.

I have learned about SMTP gateway and IMAP gateway. SMTP is Simple Mail Transfer Protocol allowing you to receive messages. While IMAP is Internet Message Access Protocol allowing us to get the email. I wrote a script to get user's emails here. This github project which I'm working on with Muhammad allows us to send and recieve messages from text with an email. Click here

In Discord you can do "`` Put your code here
``" To get different colors of your code to render.

Learned how to add React App and some components inside of a Django Rest Framework
- cd into main folder
- Create new app
django-admin startapp frontend - cd into frontend folder
- Inside of frontend folder, create
templatesdirectory andstaticdirectory - In

npm init -y - Install webpack
npm i webpack webpack cli --save-devThis package will take all our javascript and bundle it in one single js file - Install bable
npm i @babel/core babel-loader @babel/preset-env @babel/preset-react --save-devEssentially what babel does is it takes our JavaScript and code and makes sure it is compatable with other browsers. - Install react
npm i react react-dom --save-dev - Install materialUI
npm install @material-ui/corebuilt in components for us so we don't have to build everything (cards/grids) like boostrap - Install another plugin for babel
npm install @babel/plugin-proposal-class-propertiesthis is so we can use async, wait, etc commands in our JavaScript - Install plugin for react
npm install react-router-domwill let us to re route our pages - Install plugin for materialUI
npm install @material-ui/iconsGet icons for material ui
Created Django project with subapp.
- Start django project (after django has been downloaded and pipenv has started)
django-admin.py startproject termtext cd termtext- Create app
python3 manage.py startapp termtext_frontend - To run the server
./manage.py runserver - We want to use DB - SQLite, so we want to create the migrations
./manage.py migrate - To create a super user for the app run
./manage.py createsuperuserwhich allows me to create admin user name / password - Running the server again
./manage.py runserverI can put /admin in the URL and sign in with my super user credentials
Create an environment in terminal by using export, for example if I wanted to create an environment variable called email and set it, I would do the following command.
export EMAIL=myemail@gmail.com
To read the variable I could do
echo $EMAIL
I also made this in the bash mini shell, but I forgot how to do it myself haha
