akelly··on Interview with Jim Anderson, CEO of Lattice Semiconductor
Video version: https://www.youtube.com/watch?v=pDNtcBh-3o0

It's a decent overview of Lattice's business and some of their applications. Nothing too technical. A shame Ian didn't ask about open source toolchains.

My point was more nuanced than that. Of course miners are influencing GPU prices. If miners stopped buying all GPUs, prices would probably go back to MSRP pretty quickly.

But stopping miners from buying one GPU model won't make it sell at MSRP. Miners switch to buying other cards, driving the price of those even higher, but the LHR cards are still going to be out of stock everywhere and scalped for 2x MSRP, because there are so many gamers buying GPUs.

Uhhh every single one. Here's the Nvidia 3070 for example: https://www.techpowerup.com/review/nvidia-geforce-rtx-3070-f...

Most of TSMC's capacity is allocated years ahead of time. They're contractually obligated to supply AMD wafers at a predetermined price and volume.

Also, GPUs are pretty good at mining Ethereum. ASICs are only about 2x as efficient, many miners would rather have the security of knowing they can always sell their GPUs to gamers if it all comes crashing down.

Hard to tell from an ebay listing whether it was used for mining or not.

There's three main ways GPUs wear out, silicon electromigration, electrolytic capacitor dryout, and fan bearing failure. And the first two happen much faster at higher temperatures. Temperatures are similar between gaming and mining, but miners run 24/7 compared to gaming 1-2 hrs/day, so the GPUs age like 10x faster. But still, GPU failures are pretty rare, I think the concern is overblown.

They're not producing fully featured cards anymore. They're separating the market into RTX-LHR for gamers and CMP for miners.

This won't really do anything for availability or reducing scalper pricing. Miners are a sizeable proportion of sales but far from the majority. Gamers will be able to buy more of these GPUs but less of the non-LHR or AMD GPU's. GPU prices won't actually change.

The real reason Nvidia is doing this is that when mining profitability inevitably drops, either because of a crypto price crash or Ethereum moving to Proof of Stake, the miners will flood the used market and ruin Nvidia's profits for a few quarters. Nvidia is trying to get miners to buy mining-only cards, because those can't be sold to gamers down the line. They'd rather mining cards become e-waste in a few years than get resold.

People think Nvidia is doing this to try to help them get better prices now, but really Nvidia is trying to extract more money from gamers in the long term.

Octoprint is great for 1-2 printers, but quickly becomes cumbersome when running more than that. What's the best option for big print farms?
akelly··on Nvidia CEO Introduces Nvidia Ampere Architecture, Nvidia A100 GPU
For dedicated neural network use cases like vehicles, robots, and datacenters, dedicated accelerator chips are going to be huge. Tesla's been shipping custom silicon for a while, I'd be surprised if Waymo cars didn't have a TPU in them, and there's like a dozen companies making AI accelerators but as far as I know, none of them are for sale yet.
akelly··on Conclusions from analyzing Y Combinator’s investing history
I met an ex-employee, they have 500 employees in the Philippines doing annotation. They built some software to help annotate point clouds but it seems like mostly a contractor handling logistics that the tech companies would rather not deal with, and they became a unicorn because AI.
akelly··on Intel: 10nm Product Era Has Begun, 7nm on Track
Unfortunately AMD's laptop chips are a generation behind the desktop. I have the AMD Thinkpad E485, it's significantly better at gaming (which I don't do on my laptop anyway) and a bit cheaper, but Intel laptops offer a bit better performance and significantly better battery life right now. Wait a couple months for Zen 2 to reach laptops.

And i7 is a meaningless brand in laptops, it covers a wide variety of power levels and core counts.

akelly··on Why iOS 13 and Catalina Are So Buggy
Is this a product of Apple's functional structure? Most companies are divisional, so you'd have a certain number of engineers dedicated to MacOS, who have to come up with new features to ship every year, but Apple's divisional structure makes it easier for those engineers to get pulled over to work on the new iOS feature?

How do you make sure that the video doesn't push something far more important to the pagefile? Does windows have a way of telling it the priority of an item in memory, or do you have to trust a caching algorithm?
akelly··on Tech Interview Handbook
Nobody does probationary periods because few candidates would pick a probationary period offer over a standard job offer. And it's presumed that top level talent will have multiple offers on the table, and if you don't then there's something wrong with you, so having a probationary period selects for lower quality candidates.
