What about linking to the actual source rather than a 3rd party: http://dtrace.org/blogs/ahl/2016/06/19/apfs-part1/ http://dtrace.org/blogs/ahl/2016/06/19/apfs-part1/
- cm3 10y agoWell, the article on Ars seems to be authored by Adam, so it's probably a cleaned up single piece of his blog posts.
- ahl 10y agoYep! They paid me the usual fractional pittance offered to authors. edit: and to be clear I'm delighted and flattered to see my work featured in Ars!

- ryao 10y agoThis was a pleasant surprise. I am delighted to see it featured on Ars as well. :)
- lee_ars 10y agoCorrect—I reached out to Adam to ask if Ars could syndicate the piece, and then I did some minor cleanup and clarification editing on it (mostly style conformance, but also some minor grammar tweaks and a few sentence re-writes). After checking with him to make sure my changes didn't change anything substantive, we ran the piece this AM. Link wherever you'd like, of course, but the more traffic this pulls in, the more ammo I have to be able to get Adam contributing to Ars as a regular freelancer! (edit - hi, adam!) (edit^2 - corrections corrected. Apologies for the errors. I am just a simple caveman. Your mathematics confuse and annoy me!)
- jychang 10y agoThere's still some technical errors- calling 1TB 2^30 bytes for example. (It's 2^40 bytes)
- ahl 10y agoGood catch; thanks.
- cpr 10y agoAnd it's 1024^4 not ^3.
- PhantomGremlin 10y agoI used to think that (1024 vs 1000), but not any more. There's ancient precedent for the other interpretation. For example, when I was a kid growing up in NY, one of the local radio stations I listened to was WPLJ, 95.5 MHz. That's 95,500,000 cycles per second, not 100,139,008. Go back nearly 100 years, the Chicago area got a radio station called WLS[1], one of the original clear channel stations. It broadcasts at 870 KHz. That's 870,000 cycles per second, not 890,880. Much as computer people would like "kilo", "mega", "giga" etc to mean 1024^(whatever), there's a lot of precedent for doing things the old fashioned way! As Wikipedia explains: tera-, from Greek word "terastios"="huge, enormous", a prefix in the SI system of units denoting 10^12, or 1 000 000 000 000 SI is a well accepted standard. Just because it's more logical for chip designers to implement memory chips using powers of 1024 isn't a good enough reason to ignore SI.

- shawkinaw 10y agoI would hardly call it old fashioned. SI prefixes were just mis-applied to storage sizes, hence the more correct use of kibibyte (kiB) [0], mebibyte (MiB), etc. Hence also Apple's somewhat recent switch to using 1 kB = 10^3 bytes.
