The weird places we sometimes find ourselves ...

Never did I think I'd be attending the Startup World Cup to listen to other companies pitch themselves, and at the Tokyo Regionals no less πŸ˜…

Life has definitely gotten strange, but not in a bad way!

The funny thing is how NTFS deals with fragmentation and how utterly ludicrous a modern SSD is under that doctrine.

Car Subscription Features Raise Your Risk of Government Surveillance, Police Records Show Records reviewed by WIRED show law enforcement agencies are eager to take advantage of the data trails generated by a flood of new internet-connected vehicle features.

β€œLocation data is some of the most sensitive, revealing information that is generated by our devices,” EFF’s Andrew Crocker told @wired.com. β€œYou can paint a very clear picture of someone's life with just a list of all the places they've been in their car.”

Yeah, I've got so many mixed feelings about it, it's needed in some fashion, but also creates a new series of potential attack paths that would have potentially lower barriers to entry than those currently interfacing with UAC bypasses

Couldn't agree more, I think it's trying to close a gap that existed and created a lot of technical challenges for management and development, but is opening up to more issues than likely benefits
