12:49 PM aandrew: this minipcie -> pcie extension thing doesn't work
12:50 PM aandrew: don't know if it's the cable or the motherboard, but the motherboard seems to very clearly say "mini PCI express card" and not "mSATA"

09:06 PM aandrew: it's a root because power is v^2/r so to get it in terms of volts, you square root it
