Report: Twitter working on Apple TV 4 app for NFL Broadcasts and others

TwitterLogoThe New York Times is reporting that people familiar with Twitter's streaming plans, the company is making an App for the 4th generation Apple TV that would allow end users to interact with other users during a NFL game, which the company secured the rights with the football league earlier this year.

Twitter may be doing this to make the NFL deal more viable to end users and to "one up" Apple, which was said that the company was bidding on those rights before Twitter also made a bid and got the rights to stream NFL games.

Twitter is said to begin broadcasting games when the Football season officially kicks off in September.

 

Paralyzed patients regain muscle control thanks to Virtual Reality

VirualRealityGlassesA Paralyzed 32 year old women regained partial use of her legs after 13 years of not being able to do so, as this report from CNN/Money shows:

The woman, dubbed "Patient 1," is part of an ongoing research study that uses a system of brain-controlled robotics and virtual reality to restore neurological and physical interactions.

The study involved eight spinal cord injury paraplegics -- all of whom recovered partial sensation and muscle control after about a year of training. It was conducted by the Walk Again Project in São Paulo, Brazil and led by a Duke University researcher.

The conclusions from the first part of the study were published Thursday in "Scientific Reports." Research has been underway for a total of 28 months.

Dr. Miguel Nicolelis, a Duke University neuroscientist and lead researcher, told CNNMoney that the use of virtual reality technology has been key to the treatments.

"When you remain paralyzed for many years like our patients -- [between] three to 13 years -- your brain starts to forget what it's like to have legs and the concept of walking," he said.

To induce the brain to remember, the researchers created a special VR system.

When wearing a Facebook (FB, Tech30)-owned Oculus Rift headset, the patients could control a digital representation of themselves using their thoughts. At the same time, the patients wore a special long-sleeved shirt.

When the patients moved their avatars in virtual reality, the shirt sent a sensation to match the surface of whatever the patient was standing on, such as grass or sand. This fooled the brain into interpreting the sensations as feedback from the movement of the feet or legs, helping the brain remember what it's like to walk.

"If you don't provide touch, then you don't create a sense of reality," Nicolelis said.

Once the patients made progress with controlling their virtual bodies, they graduated to using a brain-controlled robotic walker to move their real bodies.

At that point, different body parts sent signals back to the spinal cord on their own.

Over time, stimulating these multiple layers of interactions helped reawaken a small number of nerves that may have survived. This created a connection again between the brain and certain muscles.

Not only has the treatment helped patients recover some of their muscle control, it has also helped them control their bodily functions, such as bladder and bowel movements. These improvements are also important because it means patients can rely less on laxatives and catheters, and that reduces infection risks.

Nicolelis hopes to track these patients for as long as possible.

And because VR and haptic systems aren't very expensive, he believes this kind of treatment can be made available widely in the future.

How to enable root user in Mac OS X

TerminalIconEditor's Note:
The following information is for advanced users.  Enabling root user should be taken very seriously because it can leave your computer open to attacks and corrupt files.  We are not responsible for damaged or lost data to this or any other tip(s) that we may provide.  Use at your own risk!

In a Unix system, the root level is a master user that can change anything he/she wants if they know how.  It is necessary to enable this access to do some administrative tasks on a system.  One only has to enable this access once.

Enabling root should be taken seriously and disabled when he/she is finished with what ever the root user needed to do.

Enabling root in Mac OS X (or even Mac OS) is a straight forward process IF one knows what to do.

  1. Do a Spotlight search for the Directory Utility.
  2. Click on the gold lock in the lower-left corner.
  3. Enter the Administrator's password when prompted.
  4. Choose [Edit] > [Enable Root User].
  5. Enter a password you wish to have for that access level.
  6. Click OK.

Now to gain access to it, follow these steps:

  1. Do a Spotlight search for the Terminal window.
  2. At the Terminal prompt, type in: su -
  3. When prompted, enter the password you put in when you first enabled root.
  4. You're now the root user.

To protect the operating system, closing the Terminal window when you're finished should automatically log the person out of root.  Always close the window when you're done with this access.

Expand Amazon Echo with IFTTT

AmazonEcho2As an Amazon Echo user, you're always looking for ways to expand the device beyond its standard capabilities.  Sure, there is the Amazon Alexa online skill store, where owners can download hundreds of Alexa skills, but what if you wanted to go beyond those skills?  It's time that all Alexa owners know of another choice - http://www.ifttt.com (which stands for "If This, Then That").

IFTTT gives a user the ability to expand not only Alexa, but other products by downloading "Recipes" for a particular device that does a certain task.  These recipes are also for Android, iOS, and others.

There are two types of recipes: DO and IF.

The DO recipe runs with just a tap of a button on an Android or iOS device enabling one to assign a certain task to a button.

The IF recipe runs automatically in the background, creating a powerful connection between you and a device.  For example, say you wanted to post a picture on Instagram and also save it to your Dropbox folder at the same time.  IF THIS, THEN THAT.

Each IFTTT recipe for the Amazon Echo is an IF recipe.  Which means that once an end user selects and download a recipe to your Echo device from an internet connected computer, that user can call (or invoke) the recipe by saying its own activation word (called Triggers).  This helps the Echo - and you - know where the skill came from.

Go ahead and login to the IFTTT web site and create a free account.  Once approved, you can search for only those IFTTT skills that will work with Alexa.  I will use the "Find My Phone" tigger as an example.

Each Trigger for a device will be represented by its logo, so you'll know what trigger is for what device.  In this case, we only want to know the skills (triggers) for Alexa.

Each trigger will have a name, description, and an ADD button at the bottom of the page.  Simply find a Tigger, go into it, and click add.  Once that's done (if this is one's first time adding a trigger) the IFTTT web site will prompt the end user for permission to access their Alexa device.  Just follow the screens.

After that, the trigger will upload the skill to the end users Alexa device.  Depending on the type of trigger it is, it may need some additional information for it to work properly.

When the Trigger is enabled, the end user involks the newly installed trigger like this:

"Alexa, trigger find my phone."

The skill will then call the number of the phone that you gave it so it'll ring and you can find your phone.

There are thousands of triggers available for the Alexa device and more is being added daily.
