About 60% of the way through. I wanted to learn more about Eisenhower after realizing I knew nothing about such a looming figure in American history (President, WWII, Interstates, etc, etc), especially given my interest in Band of Brothers, having visited Normandy, etc.
This post gave an overview of different options, and after initially leaning Ambrose due to name recognition, I am glad I gave Smith a try instead.
It has been utterly engaging. The writing is straightforward, it feels neither overly critical nor overly favorable, and the sheer amount of citations and interesting stories is mind-blowing. I've loved every minute of it.

Move the string up and down to create a wave in the string. What happens when it meets the chain? What if the overall length was all string - or all chain - instead?
In electricity, that energy has to go somewhere; when there's an impedance mismatch, the energy is typically reflected back to the source.
For audio equipment, you typically want to match impedances: this allows the energy from the source to flow to the destination unimpeded.
However - there is an exception. Sort of. If equipment is impedance matched but power-mismatched (ie, headphones can accept 5w but output from an amp is 200w), all that 200w is going to flow to headphones only able to handle 5w and blow them up.
Avoid this situation by using power-matched and impedance-matched equipment.
47:55 should be a reasonable mismatch. Those headphones don't have a single impedance, anyways. See here: https://reference-audio-analyzer.pro/en/report/hp/akg-k-240-mk2.php#gsc.tab=0

No. The issue at hand is the DMA is requiring true alternative browser support on iOS.
So not a web app at all.
Correct. The explicit point is that they aren't going to do the engineering work to add support for non-webkit webapps in iOS.

bmhatfield Link ParentThank you for linking this to me! I will give it a try again. I had tried similar instructions but found that all binaries open the launcher, even when specifying the more direct non-launcher binary.Thank you for linking this to me! I will give it a try again.

I use it as a way to sink some mindless hours into a game on easy mode (easy modes are always appreciated), practically treating it as a sandbox rather than a challenge. 2K games really made the launcher/in-game setup stuff more annoying over the past couple years, I'm not sure why they did that.
Board Game: a while ago my wife saw Parks at a game store and picked it up for some friends who made an effort to visit many of the US National Parks. It turns out Parks is actually a great game (7.7 on BGG), a little bit of engine builder meat but generally light enough that this crew (we are not hardcore gamers) can pick it up and enjoy it readily.

The challenge here that I see folks missing is two fold:
Combined, the experienced reality of heatpumps is massive electrical bills in the deep winter, and lack of indoor comfort caused by defrost cycles. For us, our equivalent propane was $200/mo, the electrical cost was $1000+.
So while everything in the article is true - and it's a huge leap that we've moved from "don't work when it's very cold" to "you can depend on only a heat pump year-round" - the experienced reality isn't QUITE what's being sold. Especially not lower energy BILLS, despite there being lower energy USE (theoretically).
EDIT: I'll also clarify that this isn't just my lived experience. There are a number of folks in a group I am in who all switched to heat pumps as their primary heat source around the same time. Nearly all (but not all) experienced the same themes and sticker shock at their electrical bills.
