I have the following batch file: @echo off REM Starts a chrome browser with multiple tabbed sites C:\Users\UserName\AppData\Local\Google\Chrome\Application\chrome.exe "site1.com" "site2.com" But when I run it, it causes the prompt to hang and renders it unusable until Chrome is closed.

How can I make setInterval also work when a tab is inactive in Chrome?
I have a setInterval running a piece of code 30 times a second.

Simple find_by_sql also does not work: Model.find_by_sql("UPDATE user s
How to override to_json in Rails?
Update: This issue was not properly explored. The real issue lies within render :json. The first code paste in the original question will yield the expected result. However, there is still a caveat. See this example: render :json => current_user is NOT the same as render :json => current_user.to_json That is, render :json will not automatically call the to_json method associated with the User obje
