How do you define a recon? Were kilograms 1024 grams, too? When did that change? It seems it's meant 1000 since metric was created in the 1700s, along with a binary prefix.
From the looks of it, software vendors were trying to recon the definition of "kilo" to be 1024.
Kilo was used outside of decimal power rules for data storage/memory because it could only use binary powers at smaller scales. Well, that's the standard we went with anyway.
They didn't 'retcon' the use of kilo as applicable to other units, they went with the closest power of two. When hard drive manufacturers decided to use power of tens it confused people and eventually got standardized by making kb power of ten and kib power of two.
From the looks of it you aren't familiar with the situation.
This is all explained in the post we're commenting on. The standard "kilo" prefix, from the metric system, predates modern computing and even the definition of a byte: 1700s vs 1900s. It seems very odd to argue that the older definition is the one trying to retcon.
The binary usage in software was/is common, but it's definitely more recent, and causes a lot of confusion because it doesn't match the older and bigger standard. Computers are very good at numbers, they never should have tried the hijack the existing prefix, especially when it was already defined by existing International standards. One might be able to argue that the US hadn't really adopted the metric system at the point of development, but the usage of 1000 to define the kilo is clearly older than the usage of 1024 to define the kilobyte. The main new (last 100 years) thing here is 1024 bytes is a kibibyte.
Kibi is the recon. Not kilo.
Kilo meaning 1,000 inside computer science is the retcon.
Tell me, how much RAM do you have in your PC. 16 gig? 32 gig?
Surely you mean 17.18 gig? 34.36 gig?
abhibeckert in this thread had a good point. Floppies used the power of ten prefixes, so it wasn't particularly consistent.
209GB? That probably doesn't include all of the RAM: like in the SSD, GPU, NIC, and similar. Ironically, I'd probably approximate it to 200GB if that was the standard, but it isn't. It wouldn't be that much of a downgrade to go to 200GB from 192GiB. Is 192 and 209 that different? It's not much different from remembering the numbers for a 1.44MiB floppy, 1.5436Mbps T1 lines, or ~3.14159 pi approximation. Numbers generally end up getting weird: trying to keep it in binary prefixes doesn't really change that.
The definition of kilo being "1000" was standard before computer science existed. If they used it in a non-standard way: it may have been common or a decent approximation at the time, but not standard. Does that justify the situation today, where many vendors show both definitions on the same page, like buying a computer or a server? Does that justify the development time/confusion from people still not understanding the difference? Was it worth the PR reaction from Samsung, to: yet again, point out the difference?
It'd be one thing if this confusion had stopped years ago, and everyone understood the difference today, but we're not: and we're probably not going to get there. We have binary prefixes, it's long past time to use them when appropriate-- but even appropriate uses are far fewer than they appear: it's not like you have a practical 640KiB/2GiB limit per program anymore. Even in the cases you do: is it worth confusing millions/billions on consumer spec sheets?
