Comment T-Mobile is best contract-free national option (Score 1) 395

If you'd prefer not to give up your first born with a contract, you can actually do so cheaper with T-Mobile ("Get More Plus" is the plan) than if you had signed a contract with them. You'll have to buy your phone at full price, but typically the plans are about $20/mo cheaper if you do without a subsidized phone. And as a bonus, there's no contract and it is cheaper over 24 months. It really gives you some visibility into exactly how much you're paying for that "free" phone elsewhere. But coming from Europe, I'm sure you understand.

I imagine the way sharedband works is that it's a VPN endpoint. If you use VPNs (essentially creating another IP layer on top of the existing one), you *can* aggregate multiple connections and even get faster single-session transfer speeds.. You just need an endpoint to connect to that has at least that much bandwidth. This appears to be part of what sharedband offers. The main issue I'd be concerned with, however, is latency.

LVM and ZFS are barely comparable. LVM provides volume level snapshots, which means, among other things, that you must pre-allocate your snapshot space ahead of time. Basically, you must anticipate and carve out how much space you think you'll need to hold your snapshot data. This makes it significantly less useful in my experience. I'd compare ZFS snapshots to FreeBSD's UFS snapshots or Microsoft's VSS. But, it's better than those. The performance penalty for using ZFS snapshots is nonexistent, for one. The snapshots are instant, and hitless (no filesystem freezes.) There's seemingly no limit to the number of them you can have. They can also be read-only or read-write (I forget if LVM does this or not).

Snapshots aren't all that ZFS does that's unique, of course. There's end-to-end checksums, optional compression, built-in volume management, quotas, reservations, transactions vs blocks, multiple caching options. Mostly it all comes down to flexibility. You can do almost anything you'd want to do with it fairly easily. It makes you look at filesystems from a different angle. It has its share of problems, but the big ticket ones have been mostly worked out at this point.

I'd also like to add that I think DTrace can be a huge time saver in the right situations. I go back and forth between which (ZFS or DTrace) I think is more useful overall.
