downloads latest snow stake

Welcome to snow stake!

what?

The snow stake is just siting there, lonely. It looks like this:

Let's make a recording of the snow stake each time it changes. Cause we can.

how to install?

This project has been packaged with Traveling Ruby, so it will work on any platform. The instructions below are for osx, but you can change the PLATFORM variable below to to either linux-x86 or linux-x86_64 for your 32 or 64 bit linux systems.

# install
VERSION='1.0.0'
PLATFORM='osx'
git clone [e-mail]:tsabat/sno_stake.git
cd snow_stake
tar xzf "stake-$VERSION-$PLATFORM.tar.gz"

# run
cd stake*
./stake

what does it do?

Each time ./stake is run, we

• do a HEAD call to the snow stake jpg
• compare the etag of the HEAD call to the last call we made
• if the etag has changed, save the jpg in the format 2017-10-13-05-56.jpg

what about cron?

Assuming you untar'd the code above in /opt/stake/stake-1.0.0-osx, you'd

create a controller file

create a script in /opt/stake called shoot_stake.sh which looks like this:

#!/bin/bash

cd /opt/stake/stake-1.0.0-osx
./stake

make stake.sh executable

chmod +x /opt/stake/shoot_stake.sh

edit your cron

to look like this to make it run every 10th minute
