How to move from Google Latitude to Google+ Location

Google Latitude is not longer present in the new version of Google Maps for Android. The social location service Google will close on August 9 after being running for over four years in Google Maps application for Android and the most popular mobile operating systems.

Google+ now has an option labeled Location in the mobile app. Tapping this tab will take you to a service that looks very similar to Latitude, with the faces of your friends and family members strewn across a large map. You can zoom in and pinpoint their last reported location, but you can’t ping them for a check in like you could in Latitude. As long as your friend is reporting their location, however, you will see them move on the map.

If you’re interested in sharing your location with others, you have to go into Google+ Location and pick who you want to share your location with. You can share publicly, so anyone with a Google+ account can see your location, or you can choose to limit your sharing to specific circles and people. If you’re an active Google+ user who uses the circle organization system, this process is really quick. If you have everyone dumped into one circle, you basically have to either put the people you want to share with in a circle and choose that circle or select each individual and share with them.

How to encrypt your emails with Secure Gmail

With the scandal of PRISM, for example, many advise encrypt your emails.

The idea that was already implicit spied on us, but we have confirmed that our sense of vulnerability raises the maximum, there is not much we can do. While we will be able to be spied on when someone in this program or other more regional and unveiled we still want it no matter how much security we have, there are ways to reduce the amount of information that will take or the increasing difficulty that will require them to find it. One of these methods is email encryption, and we recently found a Chrome extension that handles this.


- A Gmail account
- Google Chrome installed


1) Install Secure

- Open Google Chrome and go to Google Chrome Web Store:

- In the search type: Secure Gmail and enter.

- Click on Secure Gmail by Streak

- Click Add to Chrome / Click OK to confirm

2) Sending a encrypted email

- Go to Gmail

- You will find next to the Compose button, another button again. That will be how to tell the extension you want to write an encrypted email.

- Then you will see the pop of writing but with the title in red.

- Write the recipient's address, a subject and then email content normally.

- When finished, pressures on the Submit button Encryption and the extension will be prompted to enter a password to encrypt it. You can add an optional password hint in case your recipient does not know the password. *

- The email arrives in your Inbox coded container with a button to open the popup and enter the password. **


* If you use password hint, the password is information that you two have in common and no one else can find with that suggestion.

**  In the case of the recipient not having Secure Gmail extension installed, a link to the download will come attached to the same email encryption

*** A detail is that the recipient can not answer with the same email encryption, so no conversation possible. So you will need to click the lock icon next to the reply button to compose a new message with encryption.

See ya.

How to apply updates to a pool of Citrix XenServers using the xe CLI

Since this release there is a new License mode. XenServer 6.2.0 replaces the previous XenServer Free, Advanced, Enterprise, and Platinum editions. XenServer 6.2.0 no longer requires a license server or licence file to enable features, all features are enabled for free in unlicensed mode. Licenses are only required to receive Citrix Support and to enable the use of XenCenter for the installation of security and feature hotfixes. Hotfixes can continue to be installed on unlicensed hosts using the xe command line.


1) A XenServer Pool configured
2) SFTP Client/ SCP Client installed in a client machine *
3) SSH client installed in a client machine **
4) The patch that you want to install ***


* In this demo I'm using Ubuntu as client and I will use Filezilla as to upload the patch on XenServer

** I will use Terminal

*** I will install XS62E002. You can download from Citrix Site. 


1) Uploading the patch to Pool

- Upload the update to the XenServer master pool usin SFTP client.
- Upload the update file to the pool you wish to update by running the following:

xe -s -u -pw patch-upload file-name=

Here, -s refers to the name of the pool master. XenServer assigns the update file a UUID, which this command
prints. Note the UUID.*


* Once an update file has been uploaded to a XenServer host, you can use the "xe patch-list" and "xe patch-param-list" commands to view information about the file.

If XenServer detects any errors or preparatory steps that have not been taken (for example, VMs are running in the pool), it alerts you.


2) Update the pool

- Get the UUID of the update file:

xe patch-list

Copy the "uuid ( RO)" value.

- Update the pool, specifying the UUID of the update file, by running the following:

xe patch-pool-apply uuid=

- Verify that the update was applied by using the "xe patch-list" command. If the update has been successful, the hosts field contains the host UUID.

- Perform any post-update operations, as necessary (such as, rebooting the hosts).

That's it.

Hasta la proxima, enjoy!!
