So there were a few threads going around recently about a challenge to write the longest sequence of keywords in Javascript:
There are, however, a few problems:
const {PassThrough} = require('stream')
const fs = require('fs')
const d = new PassThrough()
fs.createReadStream('tt2.js').pipe(d) // can be piped from reaable stream
d.pipe(process.stdout) // can pipe to writable stream
d.on('data', console.log) // also like readable
# On the host to run the container | |
docker run --privileged -i -t -v ~/host-folder-to-mount:/root/folder-ro:ro ubuntu | |
# Inside the container | |
# Need to create the upper and work dirs inside a tmpfs. | |
# Otherwise OverlayFS complains about AUFS folders. | |
mkdir -p /tmp/overlay && \ | |
mount -t tmpfs tmpfs /tmp/overlay && \ | |
mkdir -p /tmp/overlay/{upper,work} && \ | |
mkdir -p /root/folder && \ |
