Leaks point to Samsung Galaxy S20 Ultra with mammoth 108MP camera and ... what? 16GB of RAM

Re: Problem with too much RAM

> it is when you get what should be a really small simple app that takes GBs when it should be KBs.

It amazes me that you need a gigabyte of ram to do pretty much anything, when 30 years ago, the Mac classic had one thousandth that much (1MB - yes I had to look that up), and about a thousand the processor speed too (1 core 8MHz v. 4-core 2 GHz). Of course, MacOS at the time did almost no multitasking (user level at least), was BW, etc. Still.

Yep

My first thought too. That's 1.7 GB per image (maybe - I'm assuming 16 bit color uncompressed; =108*10^6*16/10^9)

Good news: Samsung's Tizen no longer worst code ever. Bad news: It's still pretty awful

Tizen in 2020?

Now that it's 2020 - have things changed in the past 3 years? I see one article that opined that Tinzen was dead in 2018 ("Samsung Gear S4 with Wear OS: Tizen is dead" (2018) ; https://www.slashgear.com/samsung-gear-s4-with-wear-os-tizen-is-dead-24531830/). Then I see another that it dominates the Smart TV space with 21% in 2019 ("Samsung’s Tizen OS dominates global smart TV market" (2019); https://www.fiercevideo.com/video/samsung-s-tizen-os-dominates-global-smart-tv-market).

Has the culture at least with regards to "testing is irrelevant" changed?

Re: Flash Reliability and availability - independent head control?

> single interfaces for example for data access

Whenever I see a picture of multi-platter drive innards, all the heads in the head-stack are controlled as one unit. Are there drives that are built to have independent control of each head? (since they all use voice call actuators now) But would that *really* speed up things?

Re: Storage tiers

> SSD will save you some power (but at 5W to 1W that's unlikely to be significant).

What about heat generation? For that matter, for say a peta-byte scale data center, does the heat generation difference between a 12TB versus 10TB HDDs matter that much (difference between 5 12TB versus 6 10TB for total 60TB say)

(Off-direct-topic - maybe) I read somewhere that some recent HDD (I think it was a WD 12TB) had 8 platters in an inch (25.4 mm) That's 3 mm for a platter *and* a head! How on Earth do they make that work (even with helium), and protect against external vibration? And how small is a physical head if the platter density is - what it up to now - 1GB/in^2? (1.5 MB/mm^2 if my maths are right)?

(Completely off topic) Would "maths" in BrEng be pluralized in the previous - where it is talking about only one "type" of mathematics - arithmetic? Or is the "singular math" seeping back across the pond by now?

Exactly what I was thinking. How much bloody data are we talking about? Petabytes? (I'm American, so I have no visceral idea of how strong an insult "bloody" is - other than it's use in the Harry Potter films in which it seems to be G-rated. Sorry if otherwise.)
