Chrome Update to Kill Many Addons, including Blockers

Almost one in six Chrome extensions could stop working this summer thanks to a major Google update. They include one of the most prominent ad-blocking tools. An extension is a third party tool that integrates with Chrome to improve the user's experience when accessing websites. They can include tools as diverse as password managers, page translators and video downloaders, though ad blockers are perhaps the best known.

Social Media Fail of the Day: ISIS Creates Social Network ‘Khelafabook,’ Anonymous Reportedly Takes It Offline

Between threats from Anonymous and a new crackdown from Twitter, ISIS is having a tough time reaching out and recruiting new psychopaths online.

To circumvent the censorship, the Islamic militant group has reportedly created its own social network called “Khelafabook.”

The Facebook clone claims it is independent and not actually sponsored by ISIS (even though it has ISIS logos all over its homepage). It says its goal is to show the world that they don’t only “live in caves” and “carry guns,” and they vow to “will rule the world by Allah’s permission.”

Khelafabook was set up by a man in Mosul, Iraq, according to The Independent, and is hosted in Egypt. There’s also an associated Twitter account which is linked to from the site.

The site first popped up last week, but has already been taken offline “to protect the info and details of its members,” according to a message on the page.

After it was taken down, Twitter accounts associated with Anonymous appeared to claim responsibility, as Vocativ points out.

For the the time being they’ll have to look elsewhere to share their terrorist pancake recipes.

How Nick Offerman and a Greeting Card Company Trolled All Of CES


CES is one of the biggest tech events of the year. It’s when everyone convinces you that you need to buy a terrifying robot Einstein for some reason.

But Nick Offerman aka Ron Swanson and American Greetings — yeah, the greeting card company — trolled all of them.

Promising “a device like none other,” Offerman and America Greetings delivered just that. Offerman took to the stage to present… a regular greeting card that looks like:



via Mashable

Offerman, who was there to present the product had this to say:

"When I started dating my wife — her name is Megan Mullally, she's a very beautiful actress and singer and goddess — she and I loved giving each other cards," he told a crowd at the press event. "It's a very important part of our relationship, and so we've continued that practice.

"Even though there are times when it's more appropriate, of course, to send a text or an email ... when you really want to get a sentiment across, there's nothing like the artifact of the handwritten card.

D'awwww... now go buy one for you mother or something.

After years of carrying the company on his back, employee reaches breaking point when his boss informs him he needs more ‘coaching’: ‘Do you even know how to do the work?’

It seems like the higher you climb in the corporate world, the less work you actually do. Otherwise, how can you explain that every CEO in the world seems to do absolutely nothing in their own company? They come to the office twice a week at best, wander around for an hour, have a meeting or two with the people who actually have work, and then go home.

What is even more annoying, is that those types of bosses have no appreciation for the people beneath them, who work extremely hard to keep the company going, like the employee who wrote this Reddit story. OP (original poster), is the only employee left in the company who didn't give up on their CEO. He has watched everyone else quit, and yet he stayed to make sure someone in the company actually does any of the work. That was until his hopeless boss told OP he needed more 'coaching' from him, which made OP understand just how much his boss cares about his company.
