Not sure what “tame” means in this context. Performance per watt has been increasing every year for a long time and continues to do so [1]. So temperature is really just a design choice. One example, pick a performance get a power. Once

Nice variant of the Knight Tour. The 0 makes the board shape a bit odd and therefore interesting. https://en.m.wikipedia.org/wiki/Knight%27s_tour

I was really interested in how they measured power because there is a ton of nuance there. They used the metric reported by a tool that limits average power via a programmable power limiter in hardware which an interesting way to do it. To

Technically it’s figured out. Gate-all-around has been experimentally demonstrated at pitches less than FinFET. The primary problem is, who is going to pay it. The economics are very tough at these 1s of nm nodes but hopefully that’s only

To make transistors smaller, and not just draw them with finer resolution, the industry will need a new way of controlling the channel. FinFET got us here. Most likely gate-all-around will be the technique that gets the “true” geometries

Over the years I’ve learned few things are more permanent than a temporary solution.

Thanks for another cool article! This one has a lot of meat so it will take some time to go through it. One question, how useful are the patents linked to in the footnotes for your work? (I hesitate to even ask this in fear of stirring yet

My guess is sales people who’ve already established relationships pre WFH get all the sales and upstarts are unable to make inroads with new clients.

This whole thing is so multifaceted I think it’s hard to draw any conclusions from it. In CA, we have COVID and fires so I’m essentially a prisoner in my house. If you locked me in my office, my productivity might go up too. But now that

One thing I always wonder, how do other professions do it? Do civil engineers have to make a building? Do chemists have to assay a sample? What makes programming so unique?

Increasing density likely implies displacing the people presently in the expensive neighborhood for construction. In the U.S. anyway, that’s easier said than done. So that’s definitely a theoretical solution but I’m not sure how practica

Oh, I see. I completely misread that paragraph. If the metal strip is on the top of the ceramic and grounded it makes sense that it would be for ESD protection. Especially as they likely did hand assembly of the PCBs.

Quick question on the post, in the paragraph on metal gate transistors there are a couple of advantages listed. The last one says, "Third, metal-gate circuitry required an additional +12 V power supply." It's not clear to me

3nm and 5nm are just marketing names it does not represent any geometry of the transistor. Probably the best analogy is 3nm would be the average length of the side of a pixel. One draws a transistor, or anything else, from many pixels. The

That’s a part of the machine therefore it would technically be included by the statement given on the right to repair policy page. Obviously that page is meant to be a high level statement, it’s not law. But hopefully you can see my point.

I actually do support the right to repair. I even donated at the link you provided. But, as a hardware designer myself, the devil is in the details for something like this and people need to be really careful. https://repair.or
