Stop+Disable and Make Automatic+Start Windows Services using PowerShell.

When you need to make sure all Cisco services (Windows services) are stopped and set to manual but you need to do this on 20 servers and there's at least 10 services per server then you start doing things like this:

Stop and set Startup type to Manual:

Get-Service |Where-Object {($_.DisplayName -like 'Cisco*')} |foreach {Stop-Service $_.Name}
Get-Service |Where-Object {($_.DisplayName -like 'Cisco*')} |foreach {Set-Service $_.Name -StartupType Manual}

Set Startup type to Automatic and start:

Get-Service |Where-Object {($_.DisplayName -like 'Cisco*')} |foreach {Set-Service $_.Name -StartupType Automatic}
Get-Service |Where-Object {($_.DisplayName -like 'Cisco*')} |foreach {Start-Service $_.Name}

[Grails] Use Domain.withNewSession instead of refresh()

Waaaaaaay faster.
For instance, if you have a service run by a scheduled recurring Quartz job, the service seem to be attached to a thread which does not see the updated fields in the database (always returns cached values). We may refresh the whole domain calling the refresh() method on the domain class instance, or just do this:

def allCampaigns
        Campaign.withNewSession{ session ->
            allCampaigns = Campaign.findAll("from Campaign where myStatus IN ('active','paused') OR myStatus = null")
        }
