Hear me out- artisanal DRAM.

Every transistor carefully hand-wired with love, giving each bit its own individual characteristic, for more organic, natural data.

Some early memory was woven: https://en.wikipedia.org/wiki/Core_rope_memory

We could bring it back.

Or maybe models that are much more task-focused? Like models that are trained on just math & coding?

isn't that what the mixture of experts trick that all the big players do is? Bunch of smaller, tightly focused models

Not exactly. MoE uses a router model to select a subset of layers per token. This makes them faster but still requires the same amount of RAM.

You don't happen to play Foxhole [0] do you? Because if not, the logistics Collies in SOL could make good use of a person with your talents. :-) [0] https://store.steampowered.com/app/505460/Foxhole/

Hadn't heard of it before.. > Foxhole is a massively multiplayer game where nope, not my cup of tea, but thanks for the "if you like this you might like this" rec :)

No problem. It was a super insider reference to that game. It is a war game, and within the game there is a 'logistics' branch which basically produces every single bullet etc. that is ever fired. There are also 'facilities' that produce gasoline for the trucks etc. to drive. Much of the language you used in your post could have been taken straight out of the game. I knew the odds that you played it were slim but I had to ask!

I have to say I called this out few months back with my statement that the worlds needs China to get competitive on node size and crash the semiconductor market as otherwise most home users/normal people will get priced out of the market. At the time I got down voted but it is nice to be proven right

Which tells me your experience is incredibly limited. Intel was very good, and when they partnered with Micron, made objectively the best SSD's ever made (3DXPoint Optanes). I lament that they sold their storage business unit, though of all the potential buyers, SK was probably the best case scenario (they since rebranded that into Solidigm). The intel X25-E was a great drive, but it is not great by modern standards…

My experience is 10 drives from 2009-2012 that still work and 10 drives from 2014 that have failed.

Yes, we've already established your experience is incredibly limited and not indicative of the state of the market. Stop buying bad drives and blaming the industry for your uninformed purchasing decisions.

Hell, as you admitted that your experience is limited to intel, I'd wager at least one of those drives that failed were probably the 660P's, no? Intel was not immune from making trash either, even if they did also make some good stuff (which for their top tier stuff, was technically was mostly Micron's doing).

I've deployed countless thousands of solid state drives - hell well over a thousand all-flash-arrays - that in aggregate probably now exceeds an exabyte of raw capacity since. This is my job. I've deployed individual systems with more SSD's than you've owned in total from the sound of it. And part of why it's hard to kill those old drives is they are literal orders of magnitude slower, meaning it takes literal orders of magnitude more time to write the same amount of data. That doesn't make them good drives, it makes them near-worthless even when they work, especially considering the capacity limitations that come with it.

I'm not claiming bad drives don't exist, they most certainly do, and would consider over 50% of what's available in the consumer market to fit that bill, but I also have vastly higher standards than most, because if I fuck something up, the cost to fix it is often astronomical. Modern SSD's aren't inherently bad, they can be, but not necessarily so. Just like they aren't inherently phenomenal, they can be, but not necessarily so. But they do exist, at a variety of price points and use-cases.

TL;DR Making uninformed purchasing decisions often leads to bad outcomes.

Apps can't be 100MB on modern displays, because there are literally too many pixels involved. Not that I know what's going on in an Electron app heap (because there's no inspection tools afaik), but I'm guessing much of it is compiled code and the rest is images and text layout related.

Are you 100% sure every single window needs to have 8k resolution?

The size of the window is up to the user.

> Yes, DDR3 is the lowest CAS latency and lasts ALOT longer. DDR5 is more reliable. Where are you getting this info that DDR3 lasts longer? DDR5 runs at lower voltages, uses modern processes, and has on-die ECC. This is already showing up in reduced failure rates for DDR5 fleets: https://ieeexplore.ieee.org/document/11068349 The other comment already covered why comparing CAS latency is misleading. CAS latency is mea…

It has on-die ECC _because_ it is so unreliable. ECC is there to fix its terribleness from factory.

So? If the net result is more reliable memory, it doesn't matter.

Many things in electrical engineering use ECC on top of less reliable processes to produce a net result that is more reliable on the whole. Everything from hard drives to wireless communication. It's normal.

> Apps can't be 100MB on modern displays, because there are literally too many pixels involved. What? Are you talking about assets? You'd need a considerable amount of very high-res, uncompressed or low-compressed assets to use up 100MB. Not to mention all the software that uses vector icons, which take up a near-zero amount of space in comparison to raster images. Electron apps always take up a massive amount of spa…

No, I'm talking about window buffers. This is about memory not disk space.

I was talking about RAM - in that running Chromium on its own already has a preset RAM penalty due to how complicated it must be.

But window buffers are usually in VRAM, not regular RAM, right? And I assume that their size would be relatively fixed in system and depend on your resolution (though I don't know precisely how they work). I would think that the total memory taken up by window buffers would be relatively constant and unchanging no matter what you have open - everything else is overhead that any given program ordered, which is what we're concerned about.
