Unfortunately this is still in a state of trial and error. What I can describe are the steps that I took to get it work and the steps that I took to validate it works:

• https://superuser.com/questions/1200539/cannot-increase-open-file-limit-past-4096-ubuntu/1200818#1200818

First off... There are multiple levels where you can specify the maximum nr of open files:

• Based on user
• Soft limit / hard limit
• Based on process

About docker ADD...

Recently I was asked to review parts of an automated tests PR that contained a Dockerfile. And even after using Docker for about 6 years I learned something new when I found this SO question

Because image size matters, using ADD to fetch packages from remote URLs is strongly discouraged; you should use curl or wget instead. That way you can delete the files you no longer need after they’ve been extracted and you won’t have to add another layer in your image. For example, you should avoid doing things like:

ADD http://example.com/big.tar.xz /usr/src/things/
RUN tar -xJf /usr/src/things/big.tar.xz -C /usr/src/things
RUN make -C /usr/src/things all

A while ago I needed a deepcopy function in python. I found out however that for my usecase I could better build my own. I want to share it so that others might benefit as well.

If the data you're copying is simple data, deepcopy might be overkill. With simple I mean if your data is representable as Json. Let me illustrate with code:

I've used [json-generator](http://www.json-generator.com/ to get some sample json data.)

def deepCopyList(inp):
    for vl in inp:
        if isinstance(vl, list):

# this program uploads to google storage using boto and eventlet all the jpg files of a selected folder

FOLDER = "/Users/myself/Documents/" # replace this with your chosen folder
BUCKET_NAME = "whateveryourbucketname"  # replace this with your bucket name

def upload(myfile):
        c = bcon.GSConnection()

I was reading the gist @https://gist.github.com/2012250

I found the autovivification functionality of it pretty cool. If only I could have a parent reference...

Obviously this was not going to be a one-line tree. But that wasn't the goal

A simple variant:

from collections import defaultdict
