Er, McAffee is wanted for murder in Belize. Knox is wanted in Italy and will be tried in absentia.

But neither have extradition requests pending. McAfee has charges pending but they've never made it to a judge. Knox is probably going to be extradited but hasn't yet.

Until the U.S. government gets an extradition request they aren't required to, and shouldn't, do anything.

The problem with nuclear, without even going close to the radiation boogeyman, is that:

- it requres huge investement before nothing happens
- it takes years to construct a power plant
- the nuclear plants require a lot of sweet water for cooling, 24/7, and the world is running out

I'm a fan of the mini-nuclear reactors. These are about the size of a bus, can be mass-produced to make them cheaper, and require no maintenance or cooling. They are extremely fault-tolerant - they only operate in a narrow thermal band, if they get too hot or too cold the reaction shuts itself down. One produces enough energy to power a small city, or a large neighborhood in a big city. You sink them in a concrete vault and forget about them for a decade or so. When their nuclear fuel is spent, you pull them out, get rid of the waste (about the size of a softball) refurbish and refuel the reactor and put it back in the ground.

The bonus side-effect is a more stable and efficient electrical grid with fewer long-haul high voltage power lines running all over the place, more redundancy and less centralization.

Work reviews - like code reviews. Everyone "shows their work" to everyone else, and everything gets reviewed, every week. Less optimal than individual workers working at peak efficiency, but more optimal than most people screwing around with no oversight whatsoever.

It appears to use a lot of memory because it replaces the standard kernel disk cache with its own ARC, and as unused memory is wasted memory, the ARC will eat up every last bit of memory you allow it.

Well, I had 4GB of RAM, the cache ate up every bit of it and didn't run particularly well.

It's performing a checksum of your entire system. That's going to be a CPU hog. BTRFS will be no different in this regard.

Very true, but if CPU usage is a factor, on an app server say, then choosing ZFS is hardly a "no-brainer" as the OP stated.

Of course it does. It just has some limitations.

Right - what I was looking for is the ability to simply add a drive to a pool and get more drive space. With btrfs RAID1, which is what I'm using, you throw a drive in, hit rebalance, and you now have more storage, properly mirrored with distributed metadata.

- CPU and RAM overhead comparable to Software RAID 5.

In my experience it needs a lot more memory than software RAID5. Something like 1GB per TB of disk space if running RAIDZ. Scrubbing can thrash your CPU pretty good, too.

I ran ZFS for a while on a dedicated file server with a fair amount of disk space (16TB) but switched over to btrfs RAID1 as my hardware wasn't up to ZFS requirements, and I needed the capability to add new drives to the pool which ZFS doesn't handle gracefully.

Relatively speaking - computing power is cheap these days. You can build a server with more computing power of Google's first server farm for a few thousand dollars. You can virtualize everything and rent CPU power from Amazon or Rackspace or Microsoft. If you're working out of your garage you can start up a new search engine for a couple tens of thousands of dollars which, really, is hardly anything these days.

Butcoin was supposed to be money, but so far it's far to volatile to be used as a unit of account in any serious sense.

Using it as a a unit of account is a regulatory definition, not an economic one. Money is still money even if there is no concept of "Bookkeeping."

Volatility doesn't enter in to the equation, during the Weimar republic the Mark was still the currency of Germany, even though hyperinflation made it essentially worthless. Just because it isn't a good store of value doesn't mean it isn't a store of value. What matters is it's ultimate utility to the users.

Pound for pound, the amoeba is the most vicious animal on earth.
