This feels like a false dichotomy. Even if sauna doesn't impact long term health in a way that can replace exercise, that doesn't mean that it doesn't improve health.

I found that strange as well. Who were they quoting, given that the Department of War hasn’t existed since 1947 and as far as I know Jimmy Carter didn’t pretend that it still did.

From my perspective it would make a lot more sense to only allow index fund purchases as an elected official. If the economy does well you still do well, but there would clearly be no insider trading going on.

Or at least there would be less - you could only trade on the knowledge of full-market swings rather than per-company swings.

For further context, he said that the right was doing everything in their power to portray him as anything but one of them. I.e. in the absence of evidence they were attempting to pin the blame on the left.

As a local to the area, a lot of the pushback is coming from the fact that this is not a closure of public parkland, but a restriction from entering any wooded area in the province - public or private.

It’s not only crown land in this case - it’s all land, public or private.

The quote was "ultimately some responsibility lies with us to think through how those tools will be used". It's saying that we as builders have a responsibility to consider and be mindful of the impacts of what we're building. It's not saying that the maintainer of wget is directly responsible for a system used to exfiltrate data from a database of political asylees.

To take your same point to its logical conclusion, no one is responsible for evil aside from the one who pulls the trigger.

> the more acidity flavors are extracted later

The first compounds to be extracted with coffee tend to taste sharply sour, shifting to sweet and then to bitter as the brew progresses - you can actually taste this directly by sampling a bit of the coffee that drips out at the start, middle, and end phases of your brew.

I found this guide to be helpful when I was first getting started: https://www.homegrounds.co/wp-content/uploads/2021/10/Coffee...

That was tried in Ontario (cap and trade), but there was enough misinformation going around that the general populace thought it was just a standard tax on individuals.

From my own experience seeing people switch from ICE vehicles to EVs, I would guess this comes down to people not being used to one-pedal driving / regenerative braking.

New comment by lfuller in "Why a spritz of water before grinding coffee yields better results"

lfuller — Sat, 09 Dec 2023 15:17:44 +0000

I consult for a specialty coffee shop, and in my experience the electrical ground of the machine has no impact on static generation - I doubt the burrs themselves are grounded. The amount of static you get very much depends on the specific grinder you use. Our large-batch shop grinder creates massive amounts of static and requires water to be added to not end up with a mess, while our espresso grinders tend to generate less.

To your second point, one of the fascinating things about this study is that the static charge during the grinding process causes the coffee to clump - that means that by the time the water hits the coffee puck it is too late to avoid the static-induced clumping.

As I've seen several comments on this here - people have used spritzes of water to reduce static when grinding coffee for years, but the interesting part of this study was the finding that beyond reducing static, adding enough water prior to grinding actually reduces flow rate and increases extraction by preventing the creation of coffee clumps / aggregates.

So it confirms the anti-static properties that everyone already knew, but has interesting implications for increasing extraction without changing any other variables.

G100UL, the current unleaded alternative to 100LL, has been tested to act as a drop-in replacement for any and all aircraft engines that run on 100LL.

If you can run, 100LL, you can run G100UL. The main issue is with mogas (standard car gas) - many aviation engines can't run it.

They did, finally, but it shouldn't have taken this long. There was a breakdown on the regulatory side for decades.
