Slack, the cool new communications app that many of the world’s top companies have flocked to, just revealed that it’s been hacked.

Attackers were able to access a Slack database, the company said Friday morning. There’s no indication the hackers were able to decrypt passwords stored on the server, but Slack is immediately ramping up security efforts in response.

Whether it’s arguing over market share vs. profit margins, or Google Now vs. Siri, the war between Android and iOS users can sometimes can a bit heated.

But up until today, no matter how anti-Apple the crowd, I’ve never heard anyone stoop to compare Tim Cook’s company to Adolf Hitler, the mass-murdering Nazi Party leader.

That’s all changed now, however, as a new ad from Chinese Internet video site service, Jia Yueting, is drawing on the massively offensive parallel to promote its new Android smartphone.

About the only thing you can’t print on a 3-D printer is a time machine. However, the creators at Formlabs have managed to bring forward a staple from many 1950s living rooms.

OK, so 3-D printing a miniaturized replica of a Philco Predicta television isn’t exactly time travel, but you can ignore that when you realize the TV actually works.

This week, Alex has a quick look inside Apple’s secret health lab, Leander has some of his own thoughts about the hot new Becoming Steve Jobs book, Luke has important info about how hackers are brute-forcing simple passwords, Rob gives you a quick how-to on marking all those unread iMessages as read, and David has a pretty neat story about Crazy Aaron’s Thinking Putty. Wild, fun, and all Cult of Mac — that’s what we have for you in this edition of Cult of Mac Magazine!

YouTube has been supporting super-sharp 4K video for over a year now, as well as video playback at 60 frames-per-second. But for the first time, the world’s biggest video sharing platform will now allow viewers to combine the two.

iOS 8.2 was released to the public over a week ago, and already, jailbreakers are champing at the bit for a jailbreak solution that works with the latest and greatest version of Apple’s new operating system. Now it seems as if TaiG, the Chinese jailbreaking team that cracked open previous versions of iOS 8 to the public, could release an iOS 8.2 jailbreak as early as today.

Sick of the mountains of paper stacking up in your inbox? You’ve probably heard about the joys of having a paperless office, maybe even thought about setting one up, but didn’t know how.

Well, here’s how. Not only is it easy to set to do, it can totally change your life.

Here’s how to use your Mac and iPhone to effortlessly set up your own idiot-proof paperless office … the right way.

If you’re in the market for an Apple Watch, and you live in London, Paris or Tokyo, consider yourself in luck: Apple will be opening mini store-within-store kiosks in luxury local department stores, dedicated to selling its eagerly-anticipated smartwatch.

The pop-up stores are planned to open Friday, April 10, when the Apple Watch first goes on preorder, which means you can be among the first to see the Apple Watch in person.

If you haven’t used Instapaper for awhile, it might be time to dig the app out again. It’s just received a great new update to version 6.2, adding some slick features like speed reading, the ability to tweet screenshots of text, and more.

This weekend is WrestleMania and, even as a kind of lapsed fan, I still can’t help but be excited about the prospect of Daniel Bryan, Brock Lesnar, Antonio Cesaro, Dolph Ziggler and pals plying their trade on the grandest stage of ’em all.

Which, of course, makes this the perfect time for Warner Bros. Interactive and WWE to update its WWE Immortals card-based fighting game for iOS — adding the characters “Macho Man” Randy Savage and “Stone Cold” Steve Austin, plus an all-new Events System, to what was already a fun gaming experience.

When I think of young Steve Jobs, I typically picture the long-haired hippie who worked at Atari or the brilliant-but-immature co-founder who started Apple with Steve Wozniak. But here’s something I’ve not seen before: a photo of Jobs as a cherubic-but-undeniably-recognizable high school freshman.

The photo comes from the Homestead High yearbook from 1969, when Jobs was 14, and is far less well-known than the high school senior picture with which I’m already familiar.

Much has been made of the managerial differences between Tim Cook and predecessor Steve Jobs, and unsurprisingly that extends to their respective approaches to recruitment, too.

Jobs famously recruited Apple engineer Bob Belleville by telling him that, “Everything you’ve ever done in your life is shit, so why don’t you come work for me?”

Tim Cook, on the other hand, takes a slightly softer tack — as evidenced by a new Fortune article, revealing how Cook recruited Apple’s retail guru Angela Ahrendts to join the company from her previous prominent role as CEO at Burberry.

Sure, you’ve got Touch ID set up on your iPhone 6, but you’ll still need a passcode to keep your iPhone secure. If you have an older iPhone without Touch ID, or your fingerprint isn’t recognized for any reason, you’ll need to fall back on a passcode.

If you want to make your passcode even more secure, try using our recipe for a code with special characters instead of a simple number-based solution.

Steve Wozniak seems to have a complex relationship with both modern-day Apple and, particularly, the Apple Watch. In an interview at the Automate/Promat Show in Chicago yesterday, Apple’s co-founder said Apple’s foray into high-end wearables marks a very different turn for the company he helped to found.

“It didn’t seem like the company we started,” he said. “That’s not the Apple that moved the world forward.”

We all know that teens are crazy drivers. But when you put phones in their hands, things get really bad.

AAA conducted video analysis of teenagers on the road and discovered that “distraction was a factor in nearly six out of 10 moderate-to-severe teen crashes.”

The video footage speaks for itself, so just watch:

Apple Stores won’t have the Apple Watch on display for a few weeks, but anyone eager to see what the world of wrist apps will offer can already download them to their iPhone.

The first wave of Apple Watch-supported apps started hitting iTunes today, with big names like Target, Evernote, WeChat and Expedia being some of the first out of the gate. You can’t actually use the Apple Watch functionality on the apps yet (unless Tim Cook hooked you up with an early unit), but you can get an early glimpse of how some apps will dramatically change your life.

Here are some of the first Apple Watch apps you can download and their features:

If you search long enough, you can find anything on eBay and Craigslist. That includes lost, expensive military equipment that helps soldiers find roadside bombs.

The Intercept, an investigative reporting website founded by Glenn Greenwald, obtained a Navy intelligence document detailing thermal-optic-imaging and night-vision devices that wound up on a number of websites for sale, including eBay, Craigslist, texasguntalk.com and sportsfisherman.com.

Indie developer Daryl Hornsby has a novel approach for getting kids engaged with educational games: Don’t dumb things down.

That’s the key to Machineers, the clever puzzle-adventure game his company crafted to to lead kids through various programming logic concepts.

“When you say you want to target 10 to 15 year-olds, you’re told you have to make it overly colorful and bubbly, and that no kids read text,” Hornsby told Cult of Mac. “We’ve been able to prove that this is not quite the case. We’ve found that kids want to be treated like adults, but it still has to be approachable.”

Tim Cook had enormous shoes to fill when he took over as Apple CEO. After Steve Jobs’ death in 2011, doubters questioned whether the Southern engineer could keep Apple relevant. But Cook has led Apple to become the world’s most valuable company — he might be even better at running the company than Jobs ever was.

Now Fortune has named Cook the “world’s greatest leader” and published a profile full of exclusive details about Cook’s journey as Apple CEO. In the interview, Cook reveals how he developed thick skin, why he’s giving all his money to charity, and the real reasons he opened up about his sexuality.

The massive profile is well worth a read, but we’ve picked out the most interesting bits for you below.

A game like Real Racing has sophisticated graphics that, combined with the motion sensors of an iPad, give you the sensation of being behind the wheel.

The only thing missing is the actual wheel.

Ivaylo Kalburdzhiev wants iPad users to have a more comfortable drive when they play anyone of the more than 450 tilt games.

The CEO of KOLOS, slavic for colossus, has developed a gaming wheel for the iPad that launches on Kickstarter today.

You know what a rebus is — a graphic puzzle representing a word or phrase. An example would be a letter “M” sitting atop the word “day”: “M” on “day” equals “Monday.”

REBUS, a new “absurd logic game” from Jutiful, is an app containing more than 100 rebuses (with more on the way). Solve these stylish word puzzles to collect achievements you can share with friends.

By now, you’ve almost certainly heard of Meerkat: the live-streaming social media phenomenon. Well, Twitter has too, because today it launched its own would-be Meerkat killer: a standalone live-streaming video app called Periscope.

Currently available only for iOS devices, the app was acquired by Twitter back in January for a reported $100 million. Unlike Meerkat, which works on the same disappearing media idea as Snapchat, Periscope allows users to save live streams and then replay them later.

Transferring your WhatsApp data to a new device can be a pain — particularly if you’re switching from Android to another platform, or vice-versa. But WhatsApp looks set to make it a whole lot easier by giving users the ability to backup their messages to Google Drive.
