mecameron commented on An open source initiative to share and compare heat pump performance data   heatpumpmonitor.org/... · Posted by u/protontypes
_spduchamp · 2 years ago
We moved to heat-pump a few years ago and disconnected from gas. It's been working great. Our biggest expense was insulating our house. It is an old house and the 2nd floor was very drafty. You could feel a breeze coming through cracks in the wall. When we opened the wall there were just a few newspapers in there and no insulation.

We had the 2nd floor siding removed, an extra layer of insulated wall added to the outside and then cladded with siding. It was like putting a big insulated hat on our house. Now the temperature is very consistent and absolute no drafts.

The architect said to me that we'll never fully recoup our costs of putting the hat on the house. To which I replied that we don't always to things for economic reasons, and just do them because they are the right thing to do.

My only regret was going with a Rheem heat-pump water heater in this mix. It does not perform well at all. With hindsight I would have looked for a way to perhaps have water heating integrated with our air heat-pump system. There is a company called Arctic that has those systems.

Also with regard to heat-pump water heater, out big problem is that a hydronic floor heating system (installed when we were on gas) is now constantly drawing off heat from our tank. I'd like to find a small standalone unit to handle floor hydronic heating separate from my main water heating.

I am so frustrated with this analysis and sentiment when it comes to environmental investment. I understand that looking at it with a financial lens can and should be done to inform what we do, and it would be great if a project just paid for itself, but you look at all the other things we spend money on and the same calculus is not used.

People don't buy the cheapest car, house, clothing, or food they could possibly get by with, or analyze the marginal cost of moving up or down the possible price tiers available to them with only the financial payback as a guide. Yet we constantly hear the refrain that you shouldn't spend a given amount of money on solar, house improvements, appliances, etc. that might be better for the environment if the payback isn't somehow positive with a 10-20 year payback period.

I've constantly had to work with contractors to let them know that I still want to pay for the marginal costs associated with investment even knowing that the marginal financial benefit is smaller. For instance, with solar panels in less than ideal locations, tri-pane windows, etc. I have disposable income, and I think the world is trouble for the 8+ billion humans inhabiting it, so I think it's worthwhile that I would spend some of that to make it marginally better even if that means I don't have a positive financial return.

ClojureScript, Reflex, Grapefruit, Seesaw and a host of others, It's my opinion (so take it with a grain of salt) and it very well may be the way my brain works but I just find functional to not marry well to UI development. For the service and process oriented stuff associated with the front end I think it is great, but when it comes to modeling components, I find objects and inheritance work far better.

This is one of the reasons I have long been a huge proponent of Javascript despite it warts, as it can be OO when I need it to be OO and functional when I need it to be functional.

I've used ClojureScript with re-frame professionally for over 2 years, and it's been the first time in over 20 years of development that I've enjoyed working on the front-end. Unidirectional data flow with a single app atom has been a dream to work with.
mecameron commented on Is it time to treat sugar like smoking?   bbc.com/news/health-48499... · Posted by u/notlukesky

Sugar is needed for yeast to raise the dough. It's common everywhere not in the US alone. I'm in Europe and most bread has sugar added during preparation. Small amounts but still sugar.
mecameron · 7 years ago
Added sugar is not necessary for yeast. The yeast is breaking down and using the carbs naturally present in wheat. The simplest breads, like french baguettes, are only made with flour, water, salt and yeast. Sugar is added to many commercial breads because it can make production easier and more consistent and sell more to consumers, but it's not added because it's necessary.

Not to contradict your overall sentiment, but people often focus on intention with these issues. I think that's wrong.

Like, if someone treads dog poo into my house on their shoes, it doesn't really matter if they did it by mistake, or spent ages walking around town trying to find some dog poo to step in before coming to my house; the effect is that there is now dog poo on my carpet.

We need to be more dispassionate when discussing these issues because otherwise threads like this descend into analysis of whether Zuckerberg/Bezos/whoever is a moral person. Which is a)probably unknowable and b)besides the point.

There is a problem here with a very big company that has more power than it knows how to handle, which can probably only be mitigated by breaking it up. That's all there is to it, really.

[edit] Just as an addendum, that's not to say that if the company has done something illegal, the people responsible shouldn't be prosecuted- they should.

I think one thing missing in the responses here is that there is some culpability without intent. Assume there was not ill intent, the fact that so many things that went on still happens, means they didn't have sufficient controls, or checks and balances in the practices to prevent it from happening. That lack of control is itself part of the problem, and something they could have fixed any number of times.

My 9 year old son always rightfully claims that many of the harmful things he does was accidental. The problem is that he frequently leaves little margin for error in a lot of things he does. Follows his sister just a few feet behind his bike; of course your going to run into her if she stops quickly. Stacking your bowl, cup and silverware on your plate then bring it up one handed; of course they're going to spill.

Facebook's internal controls and practices are insufficient to manage their business. It doesn't matter if they didn't willfully intend to do all of the shit they did. They did intentionally create the controls, practices, and culture in place that allowed it to happen.

This "continuous deployment" for cars must be a logistical nightmare. To do repairs for a given vehicle, keeping track of what parts are backward compatible would be challenging. What if it's a compatibility breaking change? Then keeping inventory for older cars would become problematic.

Unless they do design with maximum compatibility. Then it gets interesting as upgrades are possible.

While B.EV cars maintenance is low, my car 7 months into ownership revealed bad battery cells that needed replacing. If the car was say five years old, would this replacement have been possible?

mecameron · 7 years ago
I bought a 2013 Model S recently that had its wheels swapped with a 2016 Model S by a third party before sale (I didn't care for the 21" wheels that were on the 2013, and the buyer of the 2016 wanted them). Shortly after driving away from the dealer, the tire pressure sensor system reported faults. After bringing it in to Tesla they said the newer tires and older car were not compatible, but they could easily downgrade the electronics in the wheels or upgrade the electronics on the car. They were both about the same cost, so I just had them update the wheels.

Why train employees when you can pay just a little bit more and get pretrained ones?
mecameron · 7 years ago
For when you can't find any more pretrained ones. Or to get someone for a lower salary and growing them that provides some loyalty and help solving the problem of not having enough pretrained ones in the first place.
