Someone asked whether or not acid-state was production ready. I shared my experiences:

parsonsmatt [11:32 AM] @nikolap it's used by cardano-wallet and Hackage. Based on my experience with acid-state, I'd say it is not a good choice for production data storage. For local desktop apps, SQLite is a much better choice, and for real production apps, Postgresql is king.

parsonsmatt [11:44 AM] acid-state did not have a test suite, at all, until I implemented the very first tests (for TemplateHaskell code generation) earlier this year. It has picked up some tests since then, but I'm still not confident in it's correctness.

It claims to be resilient to unplugging the power cord, but I doubt that, as it's not resilient to Ctrl-C: acid-state/acid-state#79

Time Travel Debugging

Time Travel refers to the ability to record a tab and later replay it ([WebReplay][wrr]). The technology is useful for local development, where you might want to:

• pause and step forwards or backwards
• pause and rewind to a prior state
• rewind to the time a console message was logged
• rewind to the time an element had a certain style or layout
• rewind to the time a network asset loaded

Changing the default VM Path in VMWare Fusion on OSX Yosemite:

I had a little trouble figuring this out - so making a note of it. The VMWare Fusion default location for VMs is ~/Documents/Virtual Machines.localized, which doesnt work well for me as I typically have Documents symbolically linked to my Dropbox directory and prefer to move the default VM location rather than manage exclusions on every Dropbox install I have.

It's relatively straightforward on VMWare Workstation, and Oracle VirtualBox - but for some reason

# Only reposting to avoid loosing it.

"""
When adding a many-to-many (m2m) relationship in Django, you can use a nice filter-style multiple select widget to manage entries. However, Django only lets you edit the m2m relationship this way on the forward model. The only built-in method in Django to edit the reverse relationship in the admin is through an InlineModelAdmin.

Below is an example of how to create a filtered multiple select for the reverse relationship, so that editing entries is as easy as in the forward direction.

IMPORTANT: I have no idea for what exact versions of Django this will work for, is compatible with or was intended for.
