On the energy item modern HVAC systems use a device called an ERV to greatly reduce energy loss to ventilation. No need to turn down the heat to get fresh air. The thermal plume associated with each occupant makes the problem a bit easier t

It's funny, Jobs talked a lot about being unsentimental but then he reached back to Beatles and Bob Dylan songs for quotes.

Intuitively it sounds nice but I haven't seen any actual evidence that this is what's happening. It seems a lot like the story that kids don't get COVID, a feel-good story but not really based on anything but hopeful speculat

That's more correct, also I realize I just counted number of commits rather than lines added. Close enough though, not like anyone would make any decisions with this list right?

Hard to tell, TSMC's faster cadence means you'd have to get a snapshot of total output on N7 and newer but I don't think they break that out. They report numbers here and there in the press but usually only for the new proces

I mostly agree, and the compaction of value accrued at the lower layers of the stack are a real thing, but there are two wrinkles to the industry that I find interesting. First, like advanced turbine engine technology semi development conti

Tough situation to navigate out of. They lost the process lead, now TSMC in particular does so much more volume that Intel is at a significant scale disadvantage (makes it harder to catch up). The margins in the historically lucrative serve

Thanks for recommendations. It's been a while since I've read the Carlton book, do you remember offhand any major errors?

I read that one differently. His presentation style was not as well developed as later, but setting that aside I doubt he had a grand plan. What he appeared to have is a point of view that without developers Apple was going to die no matter

The best reading on that period I'm aware of is the Jim Carleton book "Apple". He's a WSJ reporter who was covering the company at the time and the book covers the period ending around when Jobs returned but before he st

Battery life on the Apple Watch is pretty bad, for me the integration with my phone is worth it but it's a big compromise.

I recently switched from a mechanical watch to Apple Watch. Here's why: First, I wanted metrics on sleep and exercise to manage against (how am I allocating my time) and better understand how to optimize performance (e.g. even one beer

I don't know much about snow crab but Dungeness and various oysters in the Pacific Northwest US are threatened by rising ocean acidity caused by increased CO2. Warmer water is also allowing green crabs to take hold. Farther south urchi

The fab business is very sensitive to scale, with enough money and discipline you can mostly make your own luck. TSMC does way more volume than Intel and they have a very aggressive customer (Apple) that can help work out early quirks and g

In case it's not obvious the implication is that cost per good part starts to go up quickly. The wafer size and cost is essentially fixed so bigger dies mean both a lower % of parts are good and also fewer fit on the wafer in the first

I'm curious, next time I'm charging devices I'll check. Either way they're still not useful for anything beyond accessory charging, they're short and won't carry the power+signal necessary for my laptop (which,

They could have data support, I've never actually checked. The wires are pretty thin so I only trust them for charging the lights they came with. I have a bundle of similar looking A to mini or micro B cables of which I know many are c

They are charge cables that come with random accessories, I think I bought some long ones as well. Also A to C cables. As long as they're only used for low-draw devices it should be safe but requires keeping track.

They're not interchangeable, of the C cables I have now some will drive my monitor and some won't, and some don't even carry data. The type C connector is a big step up vs the older micro and A+B connectors, it just doesn&#x2

I already have three kinds of C to C cables, some that will work with my laptop+monitor and some that won't, then some power-only ones for random accessories. We can no-true-Scotsman all day but so far type C hasn't simplified my

Lightning is a better connector for small devices and it's more durable in my experience. USB-C is way better than micro as a connector but you end up with the issue of many kinds of cables that look similar but are not interchangeable

Surprisingly the display latency on TVs is regularly over 100ms, way more than latency at most homes these days (about 10ms for Comcast here).

In my experience if the "what the company does" headline seems too trivial then you have to dig deeper to understand what they're really doing. Business at scale tends to have fractal-like complexity and a lot of the work goe

This is priced around what it would cost to build something similar from scratch in the back yard of an existing house in an area like Seattle. The caveats make sense, you can easily spend $100k in permitting, site prep, and foundation if y
