Apartment Call Box “Hack”

I used to live in an apartment complex that had an electronically controlled front door to the building, coupled with a very annoying call box.

The called party just has to press 9 on their end, front door unlocks.
This method is meant to selectively admit guests to the building.

What happens if you forgot your card key? You’d have to choose your roommate’s name in the list, or hope some stranger would let you in.

Removing Nag Dialog from Proxmox 4.x

I received this tip from a co-worker on how to remove the nag dialog box upon login to the Proxmox 4.x web-UI.

  1.  Edit: /usr/share/pve-manager/ext6/pvemanagerlib.js
  2. Search for: ‘Active’
  3. Replace:
if (data.status !== ‘Active’) {


if (false && data.status !== ‘Active’) {

You will need to close and re-open your web browser / clear your cache to see the box removed.

Again like I said last time regarding guilt; there is support from Proxmox available if you feel guilty about using the “hack”

Removing the Proxmox 3.1 subscription nag dialog


If you’re annoyed by the nag dialog that pops up when you log into your Proxmox 3.1 community install, run this patch from VM server in question.

wget -O - | patch -p0

Piping that download through patch, will apply the fix to the appropriate file (/usr/share/pve-manager/ext4/pvemanagerlib.js)

Log out of the web UI, and possibly clear your browser cache / close browser window.

Having said that, there is support from Proxmox available if you feel guilty about using the patch.

Mountain Lion & Calendar

In OS X 10.8 I’ve found a few issues where the Calendar application won’t show calendars properly from any other service, including Google and iCloud. My solution was to clear the cache located in “~/Library/Calendars/Calendar Cache”

Do this with the program closed, then go into System Preferences and re-enable your Calendar accounts.
