pkgng's still missing the ability to track certain changes automatically, so you occasionally have to force-remove a package or manually change an origin as per /usr/ports/UPDATING. I think they're expecting to resolve that in 1.3 fairly soon.

I've been using it for about 18 months across a small group of machines with about 1400 packages between them, and it's pretty much entirely demolished any apt-envy I've had.

Reality disagrees with you. The user data portion of a sector is normally a power of two for convenience, being used on computers with power of two page sizes, but drives themselves are no more limited to power of two number of or size of sectors than your computer is limited to power of two size array or structure lengths, and this is readily confirmed by the existence of disks with 520 byte sectors (and somewhat different physical sizes) and an irritatingly diverse range of sector counts.

Hard disk drives use sectors which at some basic level have to be addressed by a powers of two binary addressing system. This means that no matter what else you do with sector sizes or block sizes, the binary counting system *always* comes into the picture.

Right, they're addressed using LBA48, which happens to be encoded in binary because that's how we build computers. That doesn't imply disks naturally only support powers of two for sector counts or sizes - they evidently don't.

CDs and DVDs have 2,352 and 2,418 byte physical sectors. Some Fibre Channel HD's support 520 byte sectors, and of course like optical discs all HD's have substantially bigger physical sectors internally for error detection and correction. A quick sampling of some of my HD's reveals drives with 732,566,646, 3,907,029,168, 500,118,192 and 312,581,808 sectors (at least they're all even?).

Ethernet is even more flexible, supporting any frame sizes between 64 bytes to over 9KB, hardware permitting. Note 9KB is not a power of two.

Wrong, and wrong again. *All* computer peripherals transmit data to and from computers encoded in binary signals. It means that all computer based addressing is essentially binary

Um. Yes, the numbers are encoded in binary. No, this doesn't mean computers can only handle number maximums that are a power of two. Memory happens to be like that because it has to be insanely low latency and simple bit operations like masking off the lower portion of an address is very efficient, but not everything is so restricted.

Why always picking on the HD manufacturers? Your GigE network runs at 1,000,000,000 bits per second, not 1,073,741,824, what a scam!

Memory is measured in multiples of powers of two because that's how the addressing works. Disks and network have no such fundamental limitations - they count in sectors and frames, which are themselves not necessarily powers of two.

The transaction limits on unverified payments are pretty small (£15 here in the UK, recently raised from £10), and you'd expect any such system to be wary of lots and lots of them.

The lack of signature and PIN verification also means any liability for losses through such a system rests on the bank, not you, provided you report the loss of your card in good time. Same should apply if someone manages to exploit such a feature while you still have your card, provided you dispute the payments not too long after receiving your statement.

Right, and it's less likely to die from shock or head crash or manufacturing defect, and when it runs out of erase cycles it fails soft; writes fail, but it's still readable; certainly a better failure mode than most drives. Yes, the X25-M has a 5 year design life, just as platter based drives, but I suspect it's also more likely to actually achieve it, firmware update screwups aside.
