Facebook Vs Twitter

 On Facebook, You Run Into Things Like This...

why yes, there are over 500,000 comments... Most of which do in fact say jump.

And This...

Facebook is a breeding ground for teenage drama and useless information.

 And there are SO Many of These!

It takes a special kind of person to exploit our servicemen and women to get some likes on their Facebook page... and by "special", we mean "terrible"

 Twitter Doesn't Have Annoying Apps

Don't you hate it when you get notifications and they're all app requests?

 But it Does Have Links and Hashtags

We love that Twitter makes it easy to find great new Twitter pages and sites to follow.

 And Only Some of That

This was tweeted after the theater shooting in Aurora Colorado in 2012. Some people see the trends and don't bother researching them!

But Loads of This!

We can't all be like Mike but if we were, we'd always have the best tweets.

 Facebook Lets You Share As Much As You Want

It's kind of cool that you can choose between sharing something with only specific people or just friends of friends and not the entire web.

 But Sometimes, That's a Bad Thing!

No, we don't want to hear about your breakfast today. Yes, we already know you like Brad. No, we don't want to text you. Please stop sharing your phone number every few posts!

 Twitter is Less Personal

Which isn't exactly a bad thing. No more run-ins with creep Aunt Leslie!

 But Both Are Versatile

In case you feel like you're missing out on who got dumped today, you can check your Facebook from most devices. The same goes for Twitter!

Both Have Room for Pictures

Which is good news because whether this was posted to Facebook or Twitter, plenty of people would still get to see it and make fun of one of the worst couple tattoo sets we've ever see.

13) But Twitter Doesn't Have Room for This

Dang Darrell, she seems like a keeper. Enjoy the month and a half of Facebook relationship drama!

14) Or This!

Last time we checked, the main use of Twitter wasn't to send people to hell.

15) So Twitter Wins!

It looks like we’ve all got a 140 character-sized hole in our hearts and Twitter has filled it.

How to Know If You have A Social Media Addiction?

 1)Rise and Shine

The first thing you do in the morning is brew a cup of coffee and see what's going on on your social media accounts... in fact, you probably start doing this before the coffee's even done.

 2) Fabulous Phones

You spend more time communicating through social media on your phone than through text or an actual phone call.

3) Nail News

Every time you try a new nail trend or polish color, you get more excited to post a picture of it to all of your followers than to show it off to the people in your real life.

4) Celebrity Sites

You have an entire blog or Twitter account dedicated to your favorite celebrities and you are always searching for new information to add to it.

5) Characters or Less

You plan your jokes around whether or not they would fit in 140 characters or less.

6) Checking In

You feel the need to tag your location on Facebook or check in on Foursquare every time you go anywhere... even your house!

7) This Photograph is Proof

You don't consider yourself in a relationship until you've posted pictures of you and your honey together on your Instagram/Facebook/Twitter/Goggle +.

8) Fashion Fix

You post OOTD photos of yourself all the time even though you don't have a blog or fashion-focused social media account.

9) Celebrate in Style

You never miss an opportunity to make a themed post. You buy outfits or items to wear for special events like holidays so you can post a picture of it.

10) Memes and Trends

All of your jokes and comments are based on what's getting reblogged and trending on Tumblr and Twitter.

11) Documenting Adventures

You only take pictures of your adventures so everyone can be jealous when you post them to Twitter, Instagram and Facebook.

12) Quality Time

Instead of actually enjoying the company of your friends, when you're together, you spend the whole time looking for opportunities to post to Facebook about how much fun you're having.

13) Creative Time

You spend all of your time on Pinterest pinning items you'll never actually make yourself.

14) Food Photos

Every time you eat a meal, before you take a bite or say a prayer, you arrange your plate for the perfect Instagram picture.

15) Real Life

You know more about your friends and loved ones because of their Facebook than you do from just being around them or talking face-to-face.

HEALTH .......How Much Sugar Is In Your Food?


With people living ever more frantic and fast-paced lives, we can often lose track of which essential and non-essential nutrients we consume. Sugar is vital for good health, without it all the cells in our body would come to a halt and perish. However, too much sugar raises the risk of several diseases and conditions, including rotting teeth, obesity and type 2 diabetes.
These days we're all being warned to cut down on our sugar consumption. But, sometimes we can be unaware of just how much sugar is in the food that we are eating.
To help you, we have listed some common everyday foods and drinks, together with their sugar content..

What is sugar?

Sugar is a simple carbohydrate that belongs to a class of chemically-related sweet-flavored substances. It comes in many different forms. The three main types of sugar are sucrose, lactose, and fructose.
Photograph of sugar
Even though our cells need sugar (glucose) to survive, consuming too much of it can cause numerous different health problems. Added sugar contains no beneficial nutrients and in excess only contributes to tooth decay, diabetes, and obesity.
The American Heart Association (AHA) have said that added sugars "contribute zero nutrients" and are just empty calories "that can lead to extra pounds, or even obesity, thereby reducing heart health."
Being aware of the existing and added sugar contents of the foods and drinks we consume is vital for our health - even more so today because so many products have sugar added to them.
The AHA currently recommends that men consume no more than 150 calories from added sugar per day, and women 100 calories.
Nutritionists strongly recommend against consuming more than 13 teaspoons a day.

Sugar content in common foods and drinks

To help you keep track of how much sugar you're consuming we've listed some common everyday foods and drinks, together with their sugar content. Some of these may surprise you:

How much sugar do chocolates and candy contain?

Chocolate bar
With high sugar content, chocolate should always be viewed as an occasional treat.
  • Milk chocolate bar (44g) - 5.75 teaspoons of sugar
  • Snickers bar (57g) - 7 teaspoons of sugar
  • Milky Way bar (58g) - 8.5 teaspoons of sugar
  • Marshmallows (100g) - 14.5 teaspoons of sugar
  • Caramel piece (10g) - 1.7 teaspoons of sugar
  • Butterfinger bar (60g) - 6.9 teaspoons of sugar
  • Dove chocolate bar (37g) - 5 teaspoons of sugar
  • Starburst packet (45 grams) - 5.5 teaspoons of sugar
  • Twix bar - 2.75 teaspoons of sugar
  • M&Ms packet (45 grams) - 5.75 teaspoons of sugar
  • Boiled sweets bag (100 grams) - 11.5 teaspoons of sugar

How much sugar do soft drinks contain?

Soft drinks
Soft drinks often contain a high amount of sugar.
  • Coca cola (one can) - 7 teaspoons of sugar
  • Red Bull (one can) - 7.5 teaspoons of sugar
  • Lemonade (one glass) - 5.5 teaspoons of sugar
  • Orange squash (one glass) - 2.5 teaspoons of sugar
  • Hot chocolate (one mug) - 4.5 teaspoons of sugar

A study published in Circulation, the journal of the American Heart Association, identified a link between drinking more than one soft drink a day and increased risk of developing heart disease and diabetes.

How much sugar do breakfast cereals contain?

*(per 100 grams)

  • Raisin Bran - 7.8 teaspoons of sugar
  • Frosted Flakes - 8.9 teaspoons of sugar
  • Honey Smacks - 14 teaspoons of sugar
  • Rice Krispies - 2.5 teaspoons of sugar
  • Special K - 3 teaspoons of sugar
  • Wheaties - 3.8 teaspoons of sugar
  • Trix - 8 teaspoons of sugar

  • Cookie Crisp - 8.7 teaspoons of sugar
  • Shredded Wheat - 0.1 teaspoons of sugar
  • Cocoa Pebbles - 8.6 teaspoons of sugar
  • Banana Nut Crunch - 4.7 teaspoons of sugar
In June 2012, researchers from Yale Rudd Center for Food Policy & Obesity revealed that even though cereals aimed at kids had become more nutritious, cereal companies (such as Kellogg, General Mills, and Post) had increased their advertising spending considerably. Cereal advertising aimed at children increased by 34% between 2008 and 2011.
Marlene Schwartz, deputy director of the Rudd Center, said:
"While cereal companies have made small improvements to the nutrition of their child-targeted cereals, these cereals are still far worse than the products they market to adults. They have 56% more sugar, half as much fiber, and 50% more sodium.
The companies know how to make a range of good-tasting cereals that aren't loaded with sugar and salt. Why can't they help parents out and market these directly to children instead?"

How much sugar does fruit contain?

Fruits contain fructose, a type of sugar. Fresh fruit have no "added sugar", but as you can see below, their levels of sugar range from 1 teaspoon per 100 grams in cranberries to 4 teaspoons in grapes.
*per 100 grams
Bananas
Bananas contain approximately 3 teaspoons of sugar (fructose).
  • Mangos - 3.2 teaspoons of sugar

  • Blueberries - 1.7 teaspoons of sugar
  • Cranberries - 1 teaspoons of sugar
  • Tomatoes - 0.7 teaspoons of sugar

How much sugar do cakes and desserts contain?

A medium slice of carrot cake contains approximately 3 teaspoons of sugar.
  • Banoffee pie (1 medium portion) - 4.25 teaspoons of sugar
  • Carrot cake (1 medium slice) - 3 teaspoons of sugar
  • Custard (1 medium portion) - 3.25 teaspoons of sugar
  • Chocolate mousse (1 medium portion) - 3 teaspoons of sugar

  • Sponge cake (1 medium slice) - 5.5 teaspoons of sugar
  • Swiss roll (1 roll) - 2.5 teaspoons of sugar

  • Why should I monitor my sugar intake?
  • The American Heart Association has urged people to cut their added sugar intake because of evidence that it can cause the following health conditions:
  • Main sources of added sugar calories:
    sources of added sugars in the diets of the U.S. Population 
ages 2 years and older, nhanes 2005 - 2006a

    Added sugar consumption far too high

    The U.S. Centers for Disease Control and Prevention (CDC) reported that far too many Americans are consuming too many calories from added sugars. The report revealed thatnearly 13% of adults' total caloric intake are coming from sources such as sugar and high fructose corn syrup.
    CDC adult calorie intake from sugars

    Consumers need information on "Added Sugars"

    Dr Aseem Malhotra, a cardiologist, wrote in the BMJ (British Medical Journal) last month thatdietary advice on added sugar is damaging people's health. Dr. Malhotra said "not only has this advice been manipulated by the food industry for profit but it is actually a risk factor for obesity and diet related disease."
    Food labels in the USA and Europe contain only information on total sugars per serving, and tell us nothing about added sugar. "It is therefore almost impossible for consumers to determine the amount of added sugars in foods and beverages."
    Prof. Tim Noakes, Director at the Research Unit for Exercise Science and Sports Medicine, University of Cape Town, South Africa, wrote in the same journal "Sugary sports drinks are promoted as essential for athletic performance, but are used predominantly by those without real athletic aspirations. Users need to understand that exercise may not protect them from the negative consequences of an excessive sugar intake."
    In the video below, Dr. Miriam Vos, assistant professor of pediatrics (gastroenterology) at Emory University School of Medicine explains what "added sugars" are and how they are different from the natural sugars we find in fruit or milk.

Facebook's Graph Search starts rolling out to all U.S. users

Soon, everyone who skims through Facebook in U.S. English will be able to find out who among their friends likes coffee and jazz.
Facebook announced on Monday that Graph Search will roll out over the next few weeks to everyone who signs-in to the social network in American English. Graph Search began with a relatively small test group in January and has been rolling out since then to more users who signed up for the beta. Monday’s announcement means Facebook will pick up the pace to include all U.S. English users in Graph Search.
facebook logo
Facebook says that Graph Search has become more relevant and comprehensive during the initial beta period, as well as faster.
If you haven’t had a chance to try the new feature yet, Graph Search is Facebook’s attempt to make it easier to find information about your friends and people around you. You could use Graph Search to find “people who live nearby and like cats.” As you begin typing your query, Facebook tries to help you by suggesting ways to fine tune your search in real-time. My initial cat search, for example, was for people who live “near me,” but Facebook suggested I use “nearby” instead.
Once you’ve done a search you can also refine it. For example, after searching for people who like cats, you can narrow those results down to show only people who like cats andare men, married, and work for a specific company. The tools you can use to refine a search change depending on context. So when you are searching for photos, you may find options to specify a location where the photo was taken, who took the photos, and if they include images of you. A search for companies could include options to show only businesses that employ your friends.

A distraction of dubious quality

Graph Search can be a fun way to spend the afternoon sifting through photos, likes, and your friends’ tastes in music, but there’s some question about how useful the service actually is. There are some potentially useful searches such as “Restaurants nearby my friends like” when you’re looking for something new. Likewise, finding friends or friends of friends that have traveled to Paris could come in handy if you’re looking for some travel tips before your next vacation.
But as we pointed out during the early days of Graph Search, results for restaurants your friends like can be skewed by establishments who have big social media presences, or friends who spend a lot of time hitting the “Like” button on Facebook. So while it may be interesting to see what your friends like, whether that information helps you find a great steakhouse for Friday night depends on where you live and what your friends are doing on Facebook.
Then of course, there are Graph Search’s questions around privacy , since you can’t opt out of the service. Tumblr user Tom Scott set off a mini-controversy around Graph Search in January when he was able to surface controversial results such as single women that live nearby are single and like getting drunk. Then in June, a mobile developer claimed he was able to use Graph Search to scrape 2.5 million phone numbers from Facebook user profiles.

Microsoft adds business intelligence tools to Office 365


Microsoft is adding a set of BI (business intelligence) tools to its hosted Office 365 service, including some capabilities not yet offered in stand-alone Microsoft software products.
Power BI for Office 365 “brings together our entire BI stack and offers it as a service,” said Eron Kelly, general manager for SQL Server product marketing.
microsoft office 365
Power BI will offer users what Kelly calls “self-service BI,” or “the ability for the end user closest to the business problem to bring together data and information.”
Microsoft will unveil this service at the company’s Worldwide Partner Conference (WPC) this week in Houston.
Office 365 already offers some BI capabilities. Office 365 ProPlus offers both Power View and Power Pivot through the online edition of Excel.
Microsoft Power Map
New data mapping functions using Bing Maps.
With this new service, users are given a landing page, provided by SharePoint, along with a catalog of data sources and a set of analysis tools. Excel serves as the starting point for analysis.
The data sources, chosen by an administrator, can be taken from either the organization itself, or from public data sources such as Wikipedia tables.
The user can load one or more data sources in an online Excel spreadsheet, and analyze them through a number of new tools.

A bevy of tools

One tool, called Power Query, formerly called Data Explorer, allows a user to pull external data into an Excel spreadsheet. A user, for instance, could create a spreadsheet from a Twitter feed, dividing the Twitter messages, dates, locations and users into separate columns.
Another tool, called Power Map, can place geographically coded data on a map, provided by Bing Maps. It could visually summarize, for instance, how many Twitter messages originated in each city in a country, indicating the number of messages by the height of a bar that rises above the location of the map. Power Map debuted as a beta Excel 2013 plug-in called GeoFlow.
Once a user creates a report, it can be published back to the organization’s data catalog, where others can view it. Microsoft is planning on releasing a Power BI mobile app for Windows 8 and iOS devices. Reports, which are published through Power View, can also be rendered in HTML5, in addition to Power View’s default Silverlight format.
Power BI will also come with a new natural language query engine. A user can type in a query into a search box, such as “How much revenue did product X generate last year?” and Power BI would return a graph, based on existing data, showing the revenue data for the past several years.
The natural language query engine “makes it easier for an average user who doesn’t know how to structure a proper SQL query,” Kelly said.
Pricing for Power BI has not yet been finalized, though it will be based on per-user, per-month model. Microsoft did not set a date for general availability of the service.

Weekend Project! Install the Windows 8.1 preview


It’s scorching out. Any housework that needs doing is already done. And with the long weekend ahead, it’s time for a simple computing project. Here’s one: Install the Windows 8.1 preview.
Last week, Microsoft unveiled Windows 8.1, the next iteration of its Windows 8 operating system. From a marketing standpoint, Windows 8.1 is a do-over, a bid to simplify and personalize an operating system that, quite frankly, turned off a lot of people. If you own Windows 8 and dislike it, we encourage you to follow along and consider giving Windows 8.1 a try. Not only does it have features designed to make Windows 8.1 a friendlier experience, but it has tons—yes, tons—of new features.
Note that, eventually, Windows 8.1 will be available to you, for free, when the software is released to “general availability,” most likely this fall. What Microsoft released last week is a preview, and so it may contain a bug or two. If you have any critical apps or data, make sure that you have backup copies, or that your data is also stored within Microsoft’s SkyDrive. Though I haven’t encountered a single bug in Windows 8.1, there’s no guarantee that you’ll have the same experience.
MICROSOFT
A prettier Start page. We think it makes a difference.
If you do run into problems, try visiting the Microsoft Windows 8 Preview forums. You’ll find answers to specific questions that this guide can’t cover, including the most frustrating error message, “Windows 8.1 Preview is not yet supported on this PC.” (Have you already seen this message? According to Microsoft, your PC might be running a 32-bit Intel Atom chip that’s currently unsupported.)

What to know before you start

Before you download and install Windows 8.1, consider where you’ll be running it. Is it on your main productivity machine? A spare PC? Or even within a virtual machine? Since you’ll be installing a preview version of the operating system, we recommend digging up a spare PC and installing 8.1 on top of an existing Windows 8 installation.
Installing the Windows 8.1 preview is essentially a one-way trip: Once the software is installed, there’s no going back. (And be aware that if you begin installation and then get cold feet in the middle, you’ll also have to uninstall the associated Windows Update; open the Control Panel, look for “View installed updates,” and delete KB2849636.)
If decide you really can’t stand Windows 8.1 after it’s already installed, the only way out is to restore your PC to its original factory settings, using the recovery media that came with your PC or a backup. Windows 8 users may also be able to restore their PC by performing a refresh. There’s bad news for Windows RT users, however: Microsoft says there’s no way back. At all.
The other thing to know is that if you download and install the Windows 8.1 preview, you may have to reinstall its apps when the final Windows 8.1 version is released. That said, if you choose to sit back, wait, and only upgrade when the final version is released, don’t worry—you shouldn’t have to touch a thing.
The operating system you’re upgrading from also determines the amount of data you’ll need to worry about. Basically, if you’re upgrading from Windows 8 to the Windows 8.1 preview, Microsoft anticipates that all of your data, with the exception of some apps, will be preserved. (Microsoft’s not saying which apps may need to be reinstalled, however.) Microsoft sums it up in the table below, compliments of its FAQ. Again, nothing should change when you install the preview, only when the preview expires.
Windows to Windows 8.1 compatibilityMICROSOFT
Once again: We recommend that you first back up your PC before you start. There have already been documented cases of Windows 8.1 installations going wrong, and the last thing you’ll want to happen is to lose everything. (The link just above also shows you how to safely perform such a backup operation.)
One final note before we get started with installation specifics: Some corproations don’t let you log in with your Microsoft account, and restrict you to a “local” installation. In these cases, you won’t have the full ability to sync your settings across multiple PCs. Local installations won’t work with the Windows 8.1 preview, so be sure you have signed up for a Microsoft ID, and then log in with that ID when the installation completes. (A Microsoft ID is generally your Hotmail or Outlook.com account and password.)

Download and installation

The installation process itself is rather simple. Visit preview.windows.com and follow the instructions. We’ve walked through an early version of the download process here. Tony Leung, one of our testing analysts who downloaded and installed the preview, reported that the total time needed to download and install Windows 8.1 was about two hours on a fast sysem with a solid-state disk. (Do note, however, this was during the earliest few hours of 8.1’s life, when Microsoft’s servers were slammed.)
This page has links both to the direct download of the Windows 8.1 preview as well as the ISO.
Again, you’ll need to decide whether you want to run an in-place installation or within a virtual machine—the latter isolates Windows 8.1 from the rest of your system, but sometimes incurs a performance hit. If you decide to take the virtual machine route,download the .ISO file (3.2GB for a 64-bit version, or 2.8GB for the 32-bit version).
If you need some assistance with installing Windows 8.1 within a virtual machine, try the TechNorms guide and this related discussion forum.
If you do download the ISO, you’ll also need this Microsoft product key:
NTTX3-RV7VB-T7X7F-WQYYY-9Y92F
8.1’s system requirements mirror those of current Windows 8 products. You’ll need a 1GHz or faster processor, and a DirectX 9 GPU with WDDM driver. A 32-bit system will need 1GB of RAM and 16GB of storage space, while 64-bit systems will need 2GB of RAM and 20GB of storage space. For the Windows RT 8.1 Preview, you’ll need a device that’s already running Windows RT and also has 10GB of free storage space, Microsoft says.
Once Windows begins its installation, your PC may reboot a few times while the process completes itself.

A quick tour of Windows 8.1

Once the installation completes, congratulations! You’re well on your way to enjoying Windows 8.1. After signing in with your Microsoft ID, you’ll see the familar Start screen. At this point, you’ll want to explore the best of what Windows 8.1 has to offer. Fortunately, Brad Chacos has compiled the five reasons you’ll want to upgrade to Windows 8.1.
Slide in from the right, and access the Settings charm. Now click the Personalize tab. Take a quick spin through the background options. Now click the back arrow, and then go down to “Change PC Settings” at the bottom.

In the PC Settings “Top Settings," make sure that the “Slide Show” toggle is turned on. This turns your Windows 8.1 PC into a picture frame when the lock screen is enabled. You can select pictures from the Camera Roll and even SkyDrive—although I’ve had some problems getting this to work correctly with SkyDrive. Photos uploaded via Windows Phone to SkyDrive seem to offer the best chance of working correctly. Other new features include “Corners and Edges,” where you can turn off the “hot corners” that trigger the charms, if that kind of thing annoys you.
Back to the Start page. Now start typing the name of your favorite band. The Search charm should automatically open. If your band is reasonably popular, not only should you see it pop up in the new “Everywhere” results under Search, but after clicking on the name you should see a “hero” page with a discography, biographical information, and more. What’s interesting here is that Microsoft’s Search, powered by Bing, doesn’t auto-create a “station” of random music. Instead, you can pick and choose which songs to listen to.

Unfortunately, if you go back to the Start page and type “AAA,” you’ll probably see an ad.
Go back one more time to the Start screen and click through to the desktop. Note the new “faux” Start button. Click it—whoops, you’re back on the Start page! Hit the Windows key to return to the desktop. From there, right-click the taskbar at the bottom of the screen, select Properties, and Navigation.
For me, this is the Windows 8.1 equivalent of the hidden screen in the Atari 2600 “Adventure” game. From here, you can select options to boot to the desktop, rearrange the Apps screen, and show the desktop background on the Start page, if you so wish. This doesn’t add any functionality, per se, but certainly should make you feel right at home.
Finally, there are the apps. Most if not all of the standard Windows 8 apps have either been retooled or augmented to make them consistent with Windows 8.1. If you’d like an in-depth look at the new Windows 8.1 apps, Jared Newman has you covered, from Alarm to Reading List. And don’t forget Internet Explorer 11 and SkyDrive, both of which have been beefed up for the new release, with both performance and feature enhancements.

One more note: So far, Stardock and some of the other developers who’ve designed custom solutions to “bring back” the Start menu and other legacy functionality haven’t said what their plans are for the future, or even if the software will work with Windows 8. But Microsoft clearly hopes that its new improvements will make you forget about the competition. That doesn’t mean that there aren’t a few things we hope to see in Windows 8.2, too.
