This week, Windows 10 has arrived, a look at changes YouTube has made to its mobile app, and what computer hackers made Fiat Chrysler do.

Microsoft celebrates the release of Windows 10

The latest version of Microsoft’s operating system officially released today, and to celebrate, the company is giving away $10 million in “cash and technology”. And Canadian initiatives are part of the campaign. By using the hashtag #UpgradeYourWorld, Canadians can suggest and nominate people, groups, and organizations who are “empowering others to do great things,” Microsoft Canada said in a statement.

Windows 10 is easily the best operating system Microsoft has ever released, and it includes the following slick features:

• The Start menu has been brought back to the interface to make it easier to navigate your computer.
• The new web browser is called Microsoft Edge. It lets you annotate web pages, sync between your various devices, and tracks your reading list.
• Cortana, the digital assistant, will be available in English Canada later this summer.
• Improved Mail and Calendar apps.
• With supporting devices, you can use your face, iris, or fingerprint to unlock your devices.

Windows 10 is a free upgrade for users of Windows 7 and Windows 8.1. If you’ve already reserved your upgrade, Microsoft will be rolling out the upgrade in cycles. And retail stores will be carrying free upgrade programs.

Virtually all computers manufacturers today released new systems with Windows 10 preloaded.

YouTube makes it easier to use mobile

Just in case you wondered how important mobile devices are today, YouTube has made it easier for people to watch — and shoot — videos with their smartphones. That’s because, according to a blog post, more than half of the videos watched on YouTube were watched on mobile devices.

The redesigned YouTube mobile app is available now on Android and is coming soon to iOS. The new app has three tabs across the top of the screen.

• Home tab is for discovery, where you’ll get recommendations based on what you’ve watched.
• Subscriptions gives you a quick look at the latest videos from the channels you’ve subscribed to.
• Account is where you can see your personal playlists as well as the videos you’ve uploaded.

Speaking of uploading videos, the new YouTube app makes it better for you to do that with your smartphone, too, You can now edit footage, add filters and music, and upload video all from within the YouTube app.

Chrysler recalls 1.4 million vehicles for a software update

I’m a big fan of technology in vehicles, and the automakers appear to be, too. But they’d better start taking security seriously or they’ll have bigger problems than just a recall.

Last week, Fiat Chrysler started a voluntary safety recall to patch the software in 1.4 million vehicles, including a couple of models of Jeep and Dodge Ram trucks.

This after a Wired article documented how two hackers from St. Louis were able to remotely comandeer a Cherokee being driven by the journalist who wrote the story.

The hackers were able to control the air conditioning, radio, and windshield wipers, as well as the transmission, cutting the engine while the vehicle was in the middle of the interstate. They can also cut the brakes.

The hack exploits a flaw in Fiat Chrysler’s Uconnect system, and in particular its connection to Sprint’s cellular network. Which is why Canadian drivers need not be concerned, because the company does not have cellular connectivity in vehicles being sold in Canada.

If you bought your Jeep in the U.S.? Get yourself a USB stick and download the update.
