Android 4.2+: enable USB debug mode (Nexus 4, Nexus 7, etc)

Posted by jpluimers on 2013/11/15

Researched this a long while ago, but just presented this at my Delphi cross-platform session on ITDevCon 2013 (of which some sessions have been broadcasted on YouTube):

With Android 4.2 and up, they did hide the debug mode a bit.

Perform these steps one to enable debug mode:

  1. Go to “Settings”.
  2. Scroll down to “About phone” or “About tablet”.
  3. Tap on “About phone” or “About table” to go to the “About” screen.
  4. In the “About” screen, scroll down, to “Build number”
  5. Tap on “Build number” seven (7!) times. It will give you some messages until finally it shows “You are now a developer”.
  6. (On some devices): confirm with the PIN code for your phone.

The above steps unlocked the “USB debugging” mode.

To enable or disable “USB debugging” mode:

  1. Go to “Settings”
  2. Choose “Developer Options”
  3. Choose “Debugging”
  4. Choose “USB Debugging”

ESX(i) AutoStart virtual machines: how to change the VM startup/shutdown settings (via: VMware Communities)

Posted by jpluimers on 2013/11/15

Since it usually is a one-off setting, I find it hard to remember how to configure the startup/shutdown behaviour of VM guests in an ESX(i)/vSphere environment.

Adding to the confusion is that this is a setting on your host, not on guest VMs.

Luckiliy, Jase McCarty and others explained this on the VMware communities, which I sligly edited:

Look under the configuration tab, at “Virtual Machine Startup/Shutdown”.

Choose Properties.  You can configure the startup/shutdown here.

In the VMware Infrastructure Client (on newer installs this is called VMware vSphere Client) I client you’ll want to select the host.

Then click on the Configuration Tab and you should see Virtual Machine Startup/Shutdown.

Select that and then click on Properties (this is on the upper right corer, not intuitive).

Hi Im using ESXi 4.0 and vSphere client, but the “Edit” button is grayed out or not active in the VM Startup/Shutdown propertiessystem settings. Is this license issue, does ESXi 4.0 doesnt support autostart of virtual machine anymore?

Click on the Move Up button to move a virtual machine to Automatic Startup or Any Order.

The trick is twofold:

  • there are 3 sections (a bit hidden in the documentation: Automatic Startup, Any Order and Manual StartupManual Startup is default)
  • the Move Up and Move Down buttons move VM guests not only within a section, but also across sections.

Click on the screenshot below to see a larger version. Read the rest of this entry »
