SharePoint 2013: Where is my Workflow History list?

I was trying to create a workflow, but the default 'Workflow History' list was nowhere to be see.
It appears that it was hidden, so I used PowerShell to resolve the problem:

$web = Get-SPWeb "http://myweb"
$list = $web.Lists["Workflow History"]
$list.Hidden = $false
$list.Update()

SharePoint 2013: Error updating managed account credentials

I encountered the following message when trying to change a password for a managed account: Error deploying administration application pool credentials. Another deployment may be active. An object of the type Microsoft.SharePoint.Administration.SPAdminAppPoolCredentialDeploymentJobDefinition named "job-admin-apppool-change" already exists under the parent Microsoft.SharePoint.Administration.SPTimerService named "SPTimerV4".  Rename your object or delete the existing object. The error message is self explanatory - Rename your object or delete the existing object.  I choose the latter. Powershell to the rescue. $job = Get-SPTimerJob -Identity "job-admin-apppool-change" $job.Delete() Reset the password and all should be good.

Error deploying Nintex workflow: An item with the same key has already been added

The following error cropped up: Error deploying workflow: Server was unable to process request. ---> An item with the same key has already been added. ---> An item with the same key has already been added. WTF???? A little digging unveiled the problem - I had two items in a 'Create Item' shape with the SAME DISPLAYNAME. I needed to move the second item to a new 'Update Item' shape in order for it to work. I order to get the workflow to deploy, I had to manually remove the 'duplicate' item from the serialized XML. Hooray!! It was then a simple matter of creating a new shape to update the 'duplicate' value.
