Comment Value of a currency (Score 1) 168

One of the reasons a currency has value is that you can pay taxes with it. Essentially the threat of being jailed (or your possessions being taken away) by the state unless you pay them with their currency of choice provides one of the core pillars that make normal fiat currency actually have value. Since in most countries you cannot pay your taxes with crypto, it has little value as a true currency as eventually you have to convert it into a currency you can pay taxes with, or risk being thrown in jail etc. Thus crypto is eternally destined to be subject to the same price swing as any other commodity based on supply/demand, unless a lot of governments actually let you pay your taxes with it.

Right, and scheduling them for a meeting AFAIK depends on the Free/Busy time permission set by default. Which users are perfectly able to change. See https://imgur.com/a/x8ycoJo for the default settings on the default calendar folder in a mailbox. This is easily changed in Outlook: https://technology.education.u... And yes, users usually don't want to change this. Because then they'd be inundated with meeting requests for times they are already busy. If I'm organizing a meeting involving several people and one of them is hiding their Free/Busy time for whatever reason, I'm just not going to take their schedule into account when I pick the time that best fits what availability I can see in everyone else's calendars.

Maybe this changed at some point (I don't have any old Exchange servers online to check), but the ability for other users to view your free/busy timeline is an assignable permission on your Exchange calendar. It defaults to allowing any authenticated user to see your free/busy times (because of the obvious usefulness of knowing when people have unallocated time to get them into a meeting), but you're always able to change it to not allow any access at all (or even grant more permissions like allowing certain users/groups to see subject lines etc).

Comment Unlocking terminals (Score 2, Insightful) 310

Everyone seems to be forgetting the real big security issue with this.

Accessing physical data on the system's hdd (whether encrypted or not) is not the major issue - accessing currently running programs is.

Example - John Q Sysadmin has a few open ssh sessions to some of his favourite boxes - locks his workstation so he can wander off somewhere. Anyone exploiting this to unlock his workstation now has access to his logged-in ssh terminals.

Yes, there are other ways to achieve this, including keyloggers, trojans, etc, but this makes it stupidly easy to walk past a random workstation, and potentially 10 seconds later have root access on any number of other boxes the user happened to be logged in as.

Remember guys - better be shutting down your ssh terms before you go to lunch!
