hooli42 commented on US reportedly forcing TSMC to buy 49% stake in Intel to secure tariff relief   notebookcheck.net/Despera... · Posted by u/voxadam

Tariffs kinda make sense when you have a deficit in a widely available item. Big trade deficit with Bangladesh? Sure you can buy cheap textiles from Thailand or Vietnam or something.

Unfortunately this approach does not work when you lack a viable domestic alternative and you're up against a monopoly.

What will the US do if TSMC does not blink? Not buy TSMC made chips? Obviously that is impossible, so the logical conclusion is that American consumers will end up paying the tariffs.

Yes.

> Obviously that is impossible

I assume you're willing to short Intel at this point?

>scale

This is so funny to see, and great to see said, because for decades I ran into nuclear proponents (not engineers or workers, just people into the politics) that said that nuclear was the "only" way to combat climate change (Edit: forgot a crucial clause: because "only" nuclear could scale). I would counter that nuclear does not scale in that it can't get small, and it takes forever to build or expand.

Whereas solar can go small, go big, go medium, and the same with storage these days.

Many in the nuclear world are currently hoping to scale to "modular" size, because it's become clear that with 1GW scale, in advanced economies, construction is too expensive (IMHO due to the high cost of labor compared to less advanced economies). So shifting to a more "factory" model like airplanes is the investment pitch: scale smaller and make each reactor like factory parts so that it gets cheap to build. We will see! It's got enough hype that even non-small non-modular designs are calling themselves SMRs in order to try to garner interest. And there is some interest in new nuclear these days, despite the extremely high cost, and its going towards the more expensive SMRs rather than 1GW scale reactors, because the risk of failure is on a smaller overall quantity of money.

Nuclear can't get small because of social and political reasons, not technical or economics reasons.

If you could put a small nuclear reactor in your backyard and it was assured to be safe, would you?

Right, just like how they've done on desktop environments
hooli42 · a year ago
This is exactly the situation for desktop games right now, something Epic is profiting immensely from. It's an extremely annoying situation for users, having a dozen launcher/store apps around contributing to bloat.

CRC32 is the same speed as an integer multiply, going all the way back to Nehalem (2008). 3 cycles latency, and you can start a new one each cycle (or more than one, on Zen 5).
hooli42 · a year ago
Sure, in the same way SIMD instructions get a linear speedup in theory.

If you Google the words "CRC32 is slow", you can see hundreds of people complaining about this.

It's legal the same way Airbnb and Uber are legal.

I’ve had SSDs sitting for years thought it was safe. Should I be worried or is this a liability warning?
hooli42 · a year ago
Sitting - worrisome.

Being used without too much writing -- just fine.

My understanding is that the only reliable way of long-term digital archival storage is to refresh the media you are storing things on every few years, copying the previous archives to the fresh storage.

Since storage constantly gets cheaper, 100GB first stored in 2001 can be stored on updated media for a fraction of that original cost in 2024.

If it does't have to be offline for long durations, software raid + adding a new drive every once in a while, and discarding failing drives is pretty foolproof.

AFAIK large data centers automate something like this.

Or as simple as using the hardware accelerated CRC32 that we have in our x86 CPUs.

Last time I checked, CRC32 worked surprisingly well as a hash.

hooli42 · a year ago
Hah, neat.

The 'weird' instructions can often be 3-4 orders of magnitude slower than arithmetic instructions, though I doubt that matters here.

They mentioned it is the overhead of the hashing that makes it slow compared to the trie.
hooli42 · a year ago
Hash functions can be as simple as a single modulo.
