Deep Shot uses camera to move application states between PC, phone

Friday, June 17th, 2011

Apple isn’t the only entity trying to ease users’ transitions between devices. Tsung-Hsiang Chang, a graduate student at MIT’s Computer Science and Artificial Intelligence Lab, and Yang Li, a Google employee, have developed an application that lets users transfer the state of an application from a computer to a smartphone or vice versa just by snapping a picture of the computer’s screen. Once the picture is taken, the application is opened right where the user left off.

The application is called Deep Shot, and was designed to work with Web apps. Most Web apps can describe the state they’re in with a combination of symbols, called the unique resource identifier (URI), which Deep Shot can use to seamlessly transfer the working state of an open app without the need for cables or interacting with a third-party app to handle the syncing. Deep Shot is technically a third party, but it appears to work in the background and doesn’t involve itself in a visible way with the transfer process.

With Deep Shot’s software installed on a computer and phone, users can take a picture with the phone of an open application on the computer—like a restaurant’s page on Yelp. The phone’s software will then use digital vision algorithms to figure out what application is in the picture and open it. Meanwhile, the computer transmits the corresponding URI to the phone using a WiFi connection, though “the medium can be replaced with any networking protocols,” Chang tells Ars.

The phone opens the Yelp app, reads the URI, and produces the same page without the user having to search for the restaurant again, e-mail the page to himself, or use other workarounds. Changing how much of the screen is photographed even changes how the information is displayed on the phone.

Likewise, users can throw an app’s state from a phone to the computer by taking a picture of the computer’s screen with the phone again. The phone uses the picture to figure out which computer it should connect with based on the appearance of the screen in the picture, and then pushes the app or page and its state to the computer.

Deep Shot’s system also doesn’t require linear transactions between different versions of the same app. URI transactions could also work more generally between two different kinds of mapping apps or review services, if desired. The creators note that Deep Shot could work with other software and non-Web applications, though Jeffrey Nichols, a researcher at IBM’s Almaden research center, notes that it would require an agreement on interoperability standards, which are tough to set up and maintain. Nichols told MIT News he hopes that “companies like Microsoft would really consider adding it,” but cautions that he thinks computing is moving away from native apps toward Web ones.

Deep Shot currently only works with a handful of Web apps, including Google Maps and Yelp, but the creators note that it could be made to work with any Web app that determines its state using URIs. The problem is that URIs are often used less plainly than in applications like Google Maps, so they can be harder to extract and exchange between devices.

There are some features we’d like to see added, like the ability to move working states between devices in the background, without having to have the relevant app pop open each time Deep Shot is used. We could also envision simpler additional services that could fill out Deep Shot, like if photos of text on a PC screen could become copy- and paste-able on the phone.

The app was developed at Google, so Google holds the rights, but it hasn’t put forth any official plans for it. In a space where companies are falling over each other to offer cloud and syncing services, Deep Shot could be a serious contribution to Google’s syncing arsenal.

Google Cloud Connect for Microsoft Office Unites Office With Google Docs

Wednesday, May 25th, 2011

Wouldn’t it be great if you could combine the best of Microsoft Office and Google Docs? Imagine the feature set and usability of Office with the ability of Google Docs to store documents in the cloud and share them. With Google Cloud Connect for Microsoft Office, that’s exactly what you get. This free add-in for Microsoft Office, which hails from Google, lets you save your Office documents to Google Docs, where you can use them as you would normally.

After you install the software, it runs as its own toolbar at the top of Office. When you want to save a document to Google Docs, simply click Sync, and it saves the file, and then syncs it automatically every time you save. If you want, you can change that syncing behavior, and having Google Cloud Connect sync only when you manually tell it to.

You can also use the Google Cloud Connect toolbar to share a document that you’ve saved to Google Docs. Click the Share button and a dialog box opens that lets you share your document. You can use Google Cloud Connect with multiple Google Doc accounts; simply switch from one to the other. There are a few limitations, though. You can’t use multiple accounts simultaneously, and you can’t open a document stored on Google Docs from directly within Office.

There’s no simpler way to combine the power of Microsoft Office and Google Docs than Google Cloud Connect for Microsoft Office–and you can get it for free.

Enabling the real administrator account in Windows Vista and Windows 7

Friday, January 21st, 2011

There will occasionally be times when you want unfettered administrative access to your machine without the risk inherent to simply disabling UAC. This can be accomplished quite easily by enabling the real administrator account which is disabled by default in Windows Vista and Windows 7. It is important to remember, however, that this account should not be used as your default account since it being compromised would be tantamount to allowing bad guys complete control of your PC.

The process is identical for both Vista and Windows 7 users.  First, open a command prompt. Type “compmgmt.msc” and hit enter. When the Computer Management console opens, expand Local Users and Groups and select Users as shown right.

Before you get all excited, right-click on the administrator account, uncheck the disabled box and start to celebrate your newly acquired administrative powers, you should set a password. Right-click on the account and input your desired password, selecting one as secure/obscure as possible. The warning that appears (see right) is due to the fact that you’re changing the password of the admin account from within another account. You can proceed without any worries because you will be enabling the real administrator account for the first time.

Finally, right click on the account again and select Properties. Now you can uncheck the “Account is disabled” box and activate your real administrator account. Hit OK, log out of the current account and log into your new administrator account with the password you just set. To disable the account, simply recheck the box to disable the account.

For those who prefer the simplicity of the command line UI, the same operation can be performed with the following command:

net user administrator /active:yes

The operation can be undone with this command:

net user administrator /active:no


Kill rogue processes with taskkill in Microsoft Windows

Tuesday, January 11th, 2011

There are times, regardless of your operating system, when you will need to manually kill a rogue process. Most of the time, this can easily be done with the help of the Microsoft Windows 7 Task Manager. There are times, however, when that tool doesn’t seem to have the ability to kill a rogue process. I have seen this plenty of times when trying to kill an Acronis process that has gone astray. When this happens, I have to employ a more powerful tool, taskkill, which is used from the command line.

Note: In order to run the taskkill command, you will have to open the command window. To do this, click Start | Run and type cmd in the text field or just enter cmd in the Run dialog box (access Run dialog box by clicking Win+R) (Figure A).

Figure A

Open the command window.

Using taskkill

The general syntax of the command looks like this:

taskkill [OPTIONS] [PID]

As you might expect, there are plenty of options available for this command. Some of the more helpful options are:

  • /s COMPUTER — (Where COMPUTER is the IP or address of a remote computer). The default is the local computer, so if you’re working with a command on the local machine, you do not have to use this option.
  • /u DOMAIN\USER — (Where DOMAIN is the domain and USER is the username you authenticate to). This option allows you run taskkill with the account permissions of the specified USERNAME or DOMAIN\USERNAME.
  • /p — If you use the /u option, you will also need to include the /p option, which allows you to specify the user password.
  • /fi — Allows you to run the taskkill command with filters.
  • /f — Forces the command to be terminated.
  • /IM — Allows you to use an application name instead of the PID (Process ID number) of the application.

One of the most useful options is the help switch (Figure B):

taskkill /?

Figure B

Use the help switch for the taskkill command.

Killing with application name

The simplest way to kill a rogue application with taskkill is using the /IM option. This is done like so:

taskkill /IM APPLICATION_NAME

Where APPLICATION_NAME is the name of the application you want to kill. Say, for example, Outlook is refusing to close. To close this with taskkill, you would execute the command:

taskkill /IM outlook.exe

Killing with PID

Let’s say you do not know the name of the application, but instead you know the PID of the application. To kill a process with a PID of, say, 572, you would issue the command:

taskkill /PID 572

Killing all processes owned by a particular user

What if you want to kill all processes owned by a single user? This can come in handy if something has gone awry with a user account or if the user has logged out, but some of the processes owned by that user will not go away. To manage this you would issue the taskkill command like so:

taskkill /F /FI “USERNAME eq username”

In this case, the username is the actual username that owns the processes. Note: The USERNAME option must be used in order to tell the taskkill command a username will be specified.

Killing processes on a remote machine

This one is very handy. Say something has locked up your desktop and you know exactly what application is the culprit. Let’s stick with our Outlook example from earlier. You can hop onto another machine and remotely kill that application like so:

taskkill /s IP_ADDRESS /u DOMAIN\USERNAME /IM Outlook.exe

Where IP_ADDRESS is the address of the remote machine (Note: The hostname can be substituted if the machines are able to see one another by hostname), DOMAIN is the domain (if applicable), and USERNAME is the username used to authenticate to the remote machine.

Final thoughts

The ability and power that comes with the taskkill command can be a very valuable tool that might save you from having to forcibly reboot a machine. Having a solid grasp of this tool, in conjunction with using the Windows Task Manager, will help to keep your Windows machines enjoying longer uptime and, should the occasion strike, the ability to manage a task when a virus, rootkit, or trojan has taken over your machine.
