The news has been dominated this week by U.S.-led airstrikes on ISIS compounds in Syria, and today is no different. After a seven-hour debate, the U.K. parliament voted Friday to take military action against extremist groups in Iraq, the BBC reported. After being recalled by Prime Minister David Cameron, Parliament supported airstrikes beginning as early as Sunday, in a 524-43 vote.

Here’s what we’re reading — and some other numbers we’re watching — Friday:

The portion of auto loans made last year that are considered subprime — a number that has jumped in the last five years, and caught the attention of federal regulators. There’s a side effect of this new subprime boom: More cars are being outfitted with a device allowing lenders to shut the engine down remotely if the owner misses a payment. These devices have become more and more common, the New York Times reported, and borrowers are raising serious safety concerns.

That’s how many requests the much-hyped, invite-only social networking site Ello was getting every hour on Thursday, BetaBeat reported. Ello has billed itself as a sort of anti-Facebook, pledging to stay ad-free and never sell user data.

Surprise album releases are the new endlessly hyped album releases. Thom Yorke just put out a new solo record, “Tomorrow’s Modern Boxes,” on BitTorrent for $6. That model is meant as an experiment, Pitchfork reported. Yorke’s band Radiohead has done stuff like this before, self-releasing new music through a pay-what-you like model, surprise announcements and even an iOS app.
