cbrozefsky··on The president of Toyota will be replaced to accelerate the transition to EV
At some point, the illusion that we will be able to avoid changing our transportation infrastructure in the US, will be unmaintainable.

The problem is not in EVs, it's in private automobiles, our settlement patterns, and our utter lack of funding public transportation in all of its forms.

cbrozefsky··on Heat pumps of the 1800s are becoming the technology of the future
All the ones we know of are doing mini splits and heat pump hot water, and we had no problem getting quotes and even recommendations.
cbrozefsky··on Heat pumps of the 1800s are becoming the technology of the future
They are now.

In Vermont, we are in our first year with heat pumps. Have a wood stove as backup and supplement when we want to go pantsless mode. The original oil burner is currently turned off, out of commission waiting on some parts. We could go without the wood stove, and have done so for stretches.

We installed Mistubishi Hyperheats, 3 external units, 5 heads. Zero interest financing by installer, for about 21k all in including electrical work. Earlier this year we also did air source hot water heater, for about 4k all in.

We were spoiled by the whole house air conditioning over the summer, and the heating has been performing just fine. It about doubled our electric consumption, but that bill is still less than my oil bill was, before the price of oil nearly doubled.

We're motivated primarily by a desire to minimize fossil fuel consumption, and then to mitigate volatility in fossil fuel markets. With this install we completed electrifying all utilities in the house , and have a rooftop solar array that previously offset the entirety of our consumption, but will not at current levels.

The heat pumps will just about pay for the cost difference between them and a new oil burner before their parts warranty is up. Add in the cooling, and the increased control and comfort we have, and it's a pretty sound investment, IMO.

As an anecdote, the conversation at the local bar in Rutland, VT the other night was all about people planning to get heat pumps, or promoting them after having them installed. Not wealthy tech enthusiasts, but bartenders, small business owners, and working class families. With the IRA inventives, and the price of heating oil -- it's becoming a normal thing, not an exception.

I disagree with your prediction about future humanity, but respect your perspective. I guess one way to put it would be to say that I have a bit more of a Tibetan Buddhist perspective.

I've had my hands in a carcass, pulling out organs. I have tried to make sure I made death and quick and painless as I could for chickens. I have not butchered anything bigger than that. I don't do that for all my meat.

I think we differ more about how much death and life are intertwined and inseperable, than we differ on how sacred and considerate that relationship should be.

You are correct, it was more a complaint about resource usage and costs, as opposed to a breakage of the src.ht service.

I like tofu and seitan and tvp, but my stomach has some limits on it's ability to process them. I really appreciate what vietnamese cuisine can do to imitate meat, but in general I find it best to not try and to let the ingredient do it's thing.

I know I'm talking about meat in this thread, and sourcing it, but just wanna also acknowledge that reducing intake of it, and making sure it's good is the strategy I think is best and scalable. Seems to be some consensus forming around it too.

cbrozefsky··on Learn Lisp the Hard Way
I paid for a house for myself, and one for my family with lisp, oh and a small cabin in the woods and a couple touring motorcycles. It was clojure specifically. It was precisely the automated reasoning and expert system you say is not the same kind of AI. We did some of that too, but it was peripheral and at most was an input and support for the captured and encoded and refined knowledge of human experts. That project helped pay for many houses and send kids to college, and otherwise help hundreds make a living.

Before that, I did some java and ruby, which was fun and helped pay rent. But before that I helped pay for many houses and even apartment buildings with Common Lisp. That project has paid for houses and school and living for many dozens of people over the last 20 years. It's still going.

I am not interesting in conquering anything, or winning anything, or what momentum or the power law, or economies of scale, or momentum or other efficiencies of industrial software production. People trot out those arguments all the time to explain why something can't be done, or why they can't do what they want to do, or why something they hate is winning or inevitable.

Believe in yourself and your compatriots, and if you wanna do it with lisp, find some better compatriots.

Cheers.

Yah, I mean, that's one take on it. A take that I still think confuses money with wealth and energy. That kind of metaphor works because it's still putting money as a stand-in, a generalization, an abstraction, for the social relations that reproduce our culture, that feed and clothe and educate and entertain us. It's a useful metaphor sometimes, but we should not mistake the map for the territory, the accounting for the experience.

The wealth is in the social relations and material goods even (you are not wealthy because you have the money to buy a house, you are wealthy because you have a well insulated, sturdy house). Turn the abstract capital into the means of production and (social) reproduction.

Just trying to give a pep talk, not disagreeing with your sentiment 8^)

Interestingly, on my last visit to the farm stand picking up beef, the owner was talking about how made their choice of butcher based on those principals. They take them to one whose operation was designed with consultation from Temple Grandin. She takes the cows she has raised there herself, and witnesses the operation.

I've processed chickens and ducks that I have raised. Much smaller scale, and actually when it comes to duck I'm much more about the eggs than the meat 8^)

cbrozefsky··on Big meat can’t quit antibiotics
I think regulatory capture and the power of absolutely massive monopolies in our industrial agriculture systems are what makes the problem persist. Awareness of the issue is not the obstacle. We can all be aware of it, people regularly complain about this or that part of the food system, but when we organize and fight to improve it, we meet incredible power arrayed against us. We can win, and do, but that poeer, not our lack of awareness, is the problem, IMO

I think you are just recognizing that capital is not wealth, and that the instinct to grow and preserve it is alienating you from solving the problems and generating the wealth thru cooperation with your neighbors. Buying locally, keeps more money circulating locally.

It wont offset inflation, but it makes a bigger impact on the people around you, who grow your food, ship and transport your food, sell you food and goods, install your heat pumps or wood stove, maybe even build the wood stove. The fabric of social relations that drives modern production, light industry as they sometimes call it, is what makes us collectively wealthy.

cbrozefsky··on Big meat can’t quit antibiotics
We run into that very issue in our local food system. It's a cap on the ability to grow the local food economy. The solutions people have tried include making shared USDA kitchens for food processing, but that is very complicated and I have heard more of them fail than succeed.

In capitalist systems, "sometimes" seems to be happening very often. Frequently enough now, and over history, that some very believable and actionable critiques of capital have been written, re-written, re-discovered and re-packaged -- at their root being the insight that this alienation, capture and monopoly is the result of class differentiation, capital accumulation, and production under the commodity form. That's not bullshit.

cbrozefsky··on Big meat can’t quit antibiotics
I hear you, but I also think that something must be said for the fact that I am getting all the meat I want, at prices that are competitive with and in many cases cheaper than the heavily subsidized industrial farms, but I am doing it with a family that gets none of those subsidies, and processed at a butcher in my county that doesn't get those subsidies either.

This could not scale to feed my old neighborhood in Chicago, for example. In that place, sourcing this way would be so much more expensive. I pay other prices for living in a very small city in the mountains, but this is a perk.

I guess I just want to caution us from applying the usual "privilege" critiques and pretending like only super-scalar universal solutions are worth considering.

I agree with the whole of your comment. Subsidies of industrial food systems shape our collective diets.

My diet includes bulk purchased lentils and chickpeas, rice, home-ground wheat and other very cheap staples that are the majority of my calories. We're eating lentils, beans, rice, making our own bread, and the meat is in about 1/4 our meals. I feel like we eat very well, perhaps better than I have in my whole life if I measure it by health and ethics. I spent years in Chicago where my corner bar had a Michelin star, and there were dozens of equally good places and man did I enjoy my privilege of being a well paid single remote working hacker there.

cbrozefsky··on Big meat can’t quit antibiotics
You don't fix industrial food systems with more industrial food systems. It's the industrial scale and the drive of capitalism to externalize costs and risks, and aggregate profits that is the problem.

I would prefer a traditional vegetarian diet to a "cultured meat" diet. I don't want industrial food poducts in my body.

cbrozefsky··on Big meat can’t quit antibiotics
I encourage people to look for alternative sources for their meat, for all food, really. Local food systems get you a better product, and nowadays they can also be quite cheaper with all of the profit taking and fuel/energy cost driven inflation in the industrial food supply chain.

We are blessed to be in Vermont, which has strong local food systems. We can get nearly all our produce and meat from local farms. We have been purchasing grass fed, pastured beef from Squier Family Farm, in Wallingford VT for years. We can get lamb and pork from the Bur-Ger family farm or any of a half dozen other families that show up at the local farmers market or sell in the coop.

We recently had some Omaha steaks, claiming to be grass fed, shipped to us by a family member. They absolutely sucked in comparison. I have had Butcher Box steaks that were comparable, but also much more expensive, and way more material in packaging.

For produce, we have a half dozen farms to choose from. It means eating more seasonally, but the quality of the veg is just so much greater.

Now you can see this as privilege, but it's also the result of hundreds of neighbors making the conscious decision to support their local food system. While everyone was complaining about food price increases, the local food systems were WAY more stable in their pricing, and we even saw the price of grass fed ground beef drop around here. It requires more thought and planning, but it really pays off, IMO.

cbrozefsky··on Learn Lisp the Hard Way
We've reached peak HN irony when someone asks and then poo poos the idea of Lisp being enhanced with AI support...
cbrozefsky··on Learn Lisp the Hard Way
Before there were tens of thousands of open source developers across a dozen or so language ecosystems using collaborative source control and the hard won, but sometimes forgotten, wisdom of decades of internet systems development; we had to build so much more of our stack ourselves. It was much less about finding the appropriate "libraries" or "frameworks" -- their were not that many to even choose from.

You would have to build the layers of your stack from first-principals, or perhaps second-hand mimicry of third hand descriptions. Understanding your problem, and building exactly the tool needed is a very different approach from picking the tool with the momentum, growing developer base, checklist of features, and knobs to twiddle to somehow get something approaching a solution to your problem.

In that setting, Common Lisp has a very powerful feature set; macros, CLOS, interactive debugging with restarts, dynamic redefinition and a fast runtime made to be interactively modified. It is a few days work to make a minimalist ORM, a HTML template language, or a functional query language and engine and proceed to tune it for purpose.

I think we are approaching an inflection point. The software ecosystem complexity, and the specialization of developers into frontend, backend, or specific frameworks and the absolutely unfathomable and delicate chains of transitive trust in the layers and layers of abstraction will become a liability .

Doing "more" of the same, throwing more bodies at it, rewriting the world because your UI or ORM needs a reboot, trying to attach checksums and technical proxies for dependencies as a substitute for the basic fact that you need to know what code you are running and why to be a responsible software vendor; none of this will work.

Truly powerful languages and runtimes with appropriate technology fit for purpose are the way out of this conundrum and the best path to being a responsible and effective computer programmer.

Keep your parens sharp.

cbrozefsky··on An Open Letter on the Open Gaming License, to Wizards of the Coast
I don't think "cloning D&D" is what any of these third parties are doing. It's producing add-ons, source books, or videos of them playing. That is, original content that is compatible with, and tuned for the rule system.

Regarding the ability to copyright the "method of playing" or "rules" of a game:

https://www.rpglibrary.org/articles/faqs/fl108.pdf

The US Copyright Office says it can apply to text or description, but not to the rules.

WoTC did have a patent issues for MtG, but I dont think that's going to work for D20 rules. Perhaps they will attempt to patent the OneD&D release?

Either way, it's quite clear that corporations will attempt to colonize and control our culture, and lie and scheme their way to expand their profit extraction.

"Opt out of me DoSing" you is not legit behavior -- especially when the victim has raised it with you multiple times, suggested fixes, and you have then blocked them from communicating in your issue tracker.

That's some really entitled thinking on the part of the Go team at Google, and it's sad to see people stanning for them.

They could also just add the site to that list, or better yet, make it opt in for sites instead of slamming them with shitty workers, and shitty defaults.

You know, like be good neighbors and respectful of other people's resources, maybe read robots.txt and not make excuses for why you are writing shitty stateless workers that spam the rest of the community.

cbrozefsky··on US companies are producing heat pumps that work below -20F
Others have said it, but it bears repeating. Do the air sealing and then insulation ASAP. It increases comfort and the ROI is way higher than moving to a heat pump.

I started with my old Vermont home with minimal insulation, single pane metal frame windows that would ice up, and drafts everywhere. After our first winter, we had the local efficiency program recommend a contractor who came out and measured air exchange and identified the order of work. New windows, sealing attic, re-insulating attic. We got a considerable tax credit for the work, and the comfort improvement was astounding.

Just this last summer we made the jump to mini-split heat pumps. They are working well, but I doubt that would be the case without the air sealing. We keep them set at their lowest, 61F, and supplement with a wood stove in the living room, maybe burning 2 cords a year.

As an aside, this is our first winter, and our bill for December was 300 dollars, at $0.18/kWh. That's about 25% lower than our estimated oil charges last year for the same period. However, this year oil is ~$4.6, almost 50% higher, so that hedge against fossil fuel price is really paying off. Add in the AC comfort that is largely offset by our solar array, and they are a worthy investment (oh, and 0% financing).

None of this would be working without that critical investment in air sealing and insulation.

cbrozefsky··on Some thoughts about raising the profile of Lisp
Learn it, it's great, productive, wonderful ecosystem and community, and it will get you a Lisp variant that runs in a modern deployment context and has access to maybe the biggest ecosystem of libraries out there.

You'll miss out on some of the details of cons cells, symbols and macros and such, but you'll get the meat of learning to work with a REPL, macros and all that.
