Bitcoin Linux

This repository provides two servers and two command-line programs, all which can be used independently of each other. Instructions for using both sets of programs are described below:

General setup

## Clone this repository using HTTPS or SSH
## If you use HTTPS GitHub access
git clone https://github.com/stanford-bitcoin/bitcoin-linux.git
## If you use SSH keys
git clone git@github.com:stanford-bitcoin/bitcoin-linux.git

## Enter the bitcoin-linux directory
cd bitcoin-linux

CLI: img2txt21

The img2txt21 program takes a JPEG image and converts it to text. To install:

## Enter the img2txt21 directory from the bitcoin-linux directory
cd img2txt21

## Install img2txt21 as a command
sudo pip3 install --editable .

Now you can run img2txt21 as you would any other system command:

## With a file
img2txt21 image.jpg

## In a pipeline
cat image.jpg | img2txt21

Note that img2txt21 defaults to buying optical character recognition services from an endpoint running on the local computer. To change what endpoint it uses, edit it and re-run.

CLI: translate21

The translate21 command takes text input and converts it to Chinese. To install:

## Enter the translate21 directory from the bitcoin-linux directory
cd translate21

## Install translate21 as a command
sudo pip3 install --editable .

Now you can run translate21 as you would any other system command:

## With a file
translate21 file.txt

## In a pipeline
cat file.txt | translate21

Note that translate21 defaults to buying translation services from an endpoint running on the local computer. To change what endpoint it uses, edit it and re-run.

Translate API on the text provided it. The Google API requires registering an API key and creating a paid account with a credit card (debit cards not accepted).

CLI pep8_21

The pep8_21 command takes a python file and performs PEP8 linting. To install:

## Enter the translate21 directory from the bitcoin-linux directory
cd pep8_21

## Install pep8_21 as a command
sudo pip3 install --editable .

Now you can run pep8-21 as you would any other system command:

## With a file
pep8_21 file.py

Note that translate21 defaults to buying translation services from an endpoint running on the local computer. To change what endpoint it uses, edit it and re-run.

Translation Server

To create an API key, go to the Google Developers Console and login with your Google account. Then create a project (you can give it any name), go to Credentials, and create credentials for a server API key. Save the API, you'll need it later.

After creating credentials, click Enable and manage APIs, and choose the Translate API. After enabling translate, go to the Billing screen and click Create billing account. Enter your payment details.

Now you can perform the technical setup:

## Enter the translate21 directory from the bitcoin-linux directory
cd translate21

## Install the dependencies
sudo pip install -r requirements.txt

## Set your API key in an environmental variable
export GOOGLE_TRANSLATE_API_KEY=YOUR_KEY

## Run the server
python3 translate-server.py

Server: OCR server

The Optical Character Recognition (OCR) server uses the Tesseract OCR engine on the local device to turn an image into text. To install:

## Enter the img2txt21 directory from the bitcoin-linux directory
cd img2txt21

## Install a JPEG library and tesseract-ocr
sudo apt-get install libjpeg9-dev tesseract-ocr

## Intall the Python dependencies
sudo pip install -r requirements.txt

## Run the server
python3 server.py

Server: PEP8 server

## Enter the translate21 directory from the bitcoin-linux directory
cd pep8-21

## Install the dependencies
sudo pip install -r requirements.txt

## Run the server
python3 pep8-server.py
