If CNT (Carbon Nanotubes) are displaying similar risk factors to asbestos, what is the scale difference between these? I've never felt so compelled to eat something that could kill me.

This spaghetti also reminding me of a scene from the three body problem (trying to avoid spoilers)
StringyBob commented on Hynix launches 321-layer NAND   electronicsweekly.com/new... · Posted by u/WaitWaitWha

Probably done with 3 separate litho/etch layers, where they etch and process in groups of 110 or so.

Each of those layers can have a cell, so if you have a tlc device at a 100nm pitch, you have a density of 321*3/(1e-4)^2 bits/mm, or about 1e11bits/mm2.

Fun reference: atomic density is 1atom/.5nm, so 1/5e-7^2, or 4e12/mm2 ish.

Not too far away.

Amazing, I had no idea how far things had diverged between logic and flash since the move to 3D.

https://borecraft.com/files/Comparison_Current_NAND.pdf (from 2019) has some of the cross-sections I was looking for - and that only goes up to 96 layers!

What does 'layer' mean in this context? I'm only familiar with planar style logic process nodes which have maybe up to 20 layers (and way more lithography steps to manufacture those layers), but I am completely ignorant of how the term is used for a flash process node.

How many layers are needed for each physical cell? Is it 1,2, or a lot more? Is this effectively 321 physical TLC cells stacked vertically and some planar style logic at the bottom of the stack.

Also, where do multiple pieces of silicon factor into this - I assume we might be up to 16 silicon dies deep with through-silicon-vias, which would mean a cross section of a package could actually have 5000 layers - that sounds crazy!

Intel had over 130,000 employees as of a couple of months ago.

15% layoffs is nearly 20,000 people.

StringyBob commented on Do signed/annotated Git tags have any special advantage over lightweight tags?    · Posted by u/pyeri
StringyBob · a year ago
I don’t use GitHub in my day to day work, but since I don’t see any other answers: for me the main reason it to prove the tag hasn’t been changed under me feet. It’s too easy for a lightweight tag to be changed without you knowing, whereas an annotated tag has some permanence of a date, comment, sha, author etc.

This feature ("Reactions") should've been opt-in. But Apple knows best for their users :P

Yes - extremely poorly thought out from Apple.

Has caught out multiple people at my workplace. Feature is buried in the camera pipeline of MacOS, had assumed it was a bug in zoom that it could not be properly disabled - until same thing happened in a msteams call too, so realized it wasn't the zoom feature recognition triggering!

The uncompetitiveness of Britain has been obvious for decades. For a highly developed English-speaking country it is very underrepresented in software tech.

Britain should unironically learn to code.

We’re here quietly - all working for American / multi-national companies. Just little of the Silicon Valley startup culture here in the UK.
