Keybase proof

I hereby claim:

• I am benspaulding on github.
• I am benspaulding (https://keybase.io/benspaulding) on keybase.
• I have a public key whose fingerprint is 20B3 BFB1 AD12 033F 0774 85F5 970F 8167 377B 92A4

To claim this, I am signing this object:

benspaulding

>>> class Foo(object):
...    # Immutable objects are fine as class attrs.
...    mystr = 'a' 
...    myint = 1
...    mytpl = (1,)
...
...    # But mutable objects often surprise you.
...    mylst = []
...    mydct = {}
>>> foo = Foo()

Simple Python WSGI app for testing some Nanobox stuff

The boxfile is simple, setting up only the bare minimum for this test. You will see that the engine is also very simple. I wanted one that didn’t do any magic or sniffing to install system or Python packages.

I wanted to see if I could put all the pip files and Python packages in a custom, cacheable location. For what it's worth, this all seems to work for me. You can run each command below to see the output. But I think, if this actually does work, all of these steps could be put in the Python engine.

Assign file types to be opened by a particular application.

Requires the ``duti`` program::

# This works on macOS, and on some Linux distros. If it is failing you may need
# to change the sed option `-E` to `-r`.
pipenv lock --requirements | sed -E 's/[[:space:]]+--hash=[a-z0-9]+:[a-z0-9]+//g'

These are works in progress, but they function for me and my uses.

Note that I wrote one in sh and one in fish just for exercise — the sh one will work fine if you use fish. The only time you need to pick one to match your own shell is if the files will be sourced, which is not yet supported.

Ideas

• Add a script to simply drop you into a shell on host machine with all these environment variables set. That would make it easier to run multiple commands.
• Add ability to source the files so the individual functions could be used in other places.

Test if Nanobox Python is configured properly

Sometimes getting caught up in the configuration of gunicorn or uWSGI with the configuration of nanobox can be confusing. If you are not getting what you expect, starting here can be a good way to know if you have ports configured properly.

When running nanobox run remember that:

Exclude node_modules from Backblaze backups on Mac

1. Edit the file at /Library/Backblaze.bzpkg/bzdata/bzexcluderules_editable.xml.
2. Add this rule inside the bzexclusions tag:

<!-- Exclude node_modules. -->
<excludefname_rule plat="mac" osVers="*"  ruleIsOptional="t" skipFirstCharThenStartsWith="users/" contains_1="/node_modules/" contains_2="*" doesNotContain="*" endsWith="*" hasFileExtension="*" />
