rileypeterson / django_annotate_date_time_convert_tz.py
Created October 8, 2022 22:40
Convert timezone in django annotate with date and time fields
# Insane Django operation I had to do
# Inspired by: https://stackoverflow.com/a/70552577/8927098
# Need to filter for a date, but source table date is in UTC and it's separated into date and time fields
# Example:
# Date to find (America/New_York): 2005-09-08
# Date in table (UTC): 2005-09-09
# Time in table (UTC): 01:07:00

rileypeterson / redact_pdf.py
Created March 15, 2021 08:00
Redact phrases of text from a PDF using Python and (only) PyPDF2. Would need to modify (trivial) for multiple pages.
import PyPDF2
from PyPDF2 import PdfFileReader, PdfFileWriter
from PyPDF2.generic import StreamObject, DecodedStreamObject
from PyPDF2 import filters
# You change the phrases/text you want redacted and the file paths:
phrases = ["123-45-6789", "YOUR_SECRET_PASSWORD", "YOUR_SECRET_ID"]
read_path = "/path/to/yourpdf.pdf"
write_path = "/path/to/yourpdf-redacted.pdf"

rileypeterson / tmux_remote_execution.sh
Created February 16, 2021 08:37
Execute remote scripts via ssh and tmux (detached). This is much more convenient than nohup, etc. and it lets you actually re-attach to session if you want to ssh in and check on it :)
ssh username@your.machine.address -t 'tmux new-session -d "sleep 20"'
# or change "sleep 20" --> "python my_time_consuming_python_script.py"

Backtrader setup

From terminal run jupyter qtconsole & # Start ipython terminal

In python: %matplotlib qt5

Then when using cerebro.plot make sure iplot kwarg is False (i.e. cerebro.plot(iplot=False)).
