Searching gists with qualifiers

When searching for gists on GitHub, you can use various qualifiers to refine your search. Here are some useful keys you can utilize:

user: - Search gists created by a specific user (e.g., user:foobar).
public: - Find public gists (e.g., public:true).
private: - Find private gists (e.g., private:true).

Using Docker to OCR text from a scanned PDF

docker container run --rm -d -v "${PWD}":/tmp/zfoo --name ocr ubuntu sleep inf

docker container exec -i ocr /bin/bash << 'eof'
  export DEBIAN_FRONTEND=noninteractive
  apt-get update
  apt-get install -y python3-pip vim less tree tesseract-ocr ghostscript
 pip3 install --break-system-packages ocrmypdf

Learning Linux via LinkedIn Learning and Docker

LinkedIn Learning

Here's a link to a LinkedIn Learning course called "Learning Linux Command Line"

https://www.linkedin.com/learning/learning-linux-command-line-14447912/

You can access the course via the ABQ Library website:

Creating a data-only Docker image

# Creating the data
echo "Hello, world" > data.txt

# Creating an image with the data
{ cat <<'eof'
from scratch
workdir /data

Proccess and kill signals

These are best practiced in a virtual environment. Docker will do.

$ docker run --rm -it ubuntu /bin/bash

Here we create a background process, capture its process id ( PID ), and then kill it.

Angular in Docker

cut -c3- <<'eof' > Dockerfile
  FROM node
  
  WORKDIR /app
  SHELL ["/bin/bash","-c"]
  
 RUN apt-get update &amp;&amp; apt-get dist-upgrade -y

Create background container

docker container run --rm -d --name gql -p 8000:80 ubuntu sleep inf
sleep 2

Configure container

{ cat <<'eof2'

	def foo():
	return("hello, world")
