Portability with knative

Three functions from the OpenFaaS store have been packaged as "knative serving" definitions. No change to the container or code is needed.

• Inception - identify the content of images with machine-learning - is it a bird, a plane or what?

• NodeInfo - give system info, pass "verbose" as the body for network adapters etc.

#How to create a .file or .folder on Windows

There are several ways

1. Rename

• Create file.txt
• Rename to .file., the last dot will be dropped, you'll have .file

Works the same with a file or a directory.

How to recover lost Python source code if it's still resident in-memory

I screwed up using git ("git checkout --" on the wrong file) and managed to delete the code I had just written... but it was still running in a process in a docker container. Here's how I got it back, using https://pypi.python.org/pypi/pyrasite/ and https://pypi.python.org/pypi/uncompyle6

Attach a shell to the docker container

Install GDB (needed by pyrasite)

apt-get update && apt-get install gdb
