leethargo··on Rice fuels diabetes and climate crises
Brown rice might not cause diabetes (if other rice does at all), but the methane from production will be the same.
leethargo··on Rice fuels diabetes and climate crises
It's unfortunate that sources are not specified, but the methane emissions from rice paddies are well known, I believe. I didn't find absolute numbers, but OWID does list them as significant (though less than from animal): https://ourworldindata.org/emissions-by-sector#annual-ch4-em...

I did not hear about the rice-diabetes connection before, but "golden rice" was developed specifically to deal with the nutritional deficiencies caused by rice (over)consumption: https://en.wikipedia.org/wiki/Golden_rice

leethargo··on Rice fuels diabetes and climate crises
One issue is methane emissions from the rice paddies, which is a rice-specific phenomenon which you wouldn't have growing wheat, millet etc.

I think potatoes is what the Chinese government was already promoting for some years.

According to the bar chart in the article, chocolate and coffee are also big factors. Why are these not talked about more?

I'm guessing their impact is mostly from deforestation. Does somebody know more?

leethargo··on TIL There's Another YAML
Sounds great. I see this is still a professional place with hired staff etc.

The website is cute: I like that the image thumbnails show cropped parts rather than scaled summaries.

Good luck! Be aware that suburbia exists in Germany as well (I'm still stuck in it).

Can you say more about that Kita's organization?

We moved away from Berlin to the south and hope to find a Kindergarden for our 2nd child, but there's not really any guarantees.

leethargo··on Adding C-style for loops to Python (2022)
One of the benefits of implementing your own module finder and loader is that you could use a separate file extension to avoid confusion with actual Python code.
leethargo··on Adding C-style for loops to Python (2022)
True, but I think that source transformation on import are already supported in Python ("officially") based on importlib [0-1].

Here's an example use cases where the author is trying to create a Python enum from Thrift specs: [2]. The issue here is that the spec code is not necessarily valid Python, but can be fixed easily with some search & replace operations.

I use icebreaker brand, made of merino wool. They are among the most expensive, but I can wear the long underpants for weeks without them smelling bad.
leethargo··on Trading with BDDs
A great resource for optimization with decision diagrams is the website by Willem-Jan van Hoeve from Carnegie Mellon [1].

They go beyond binary (the M in MDD stands for multi-valued) and they derive primal heuristics and relaxations from cropped/merged diagrams of bounded size.

leethargo··on Ask HN: What RSS Reader do you use in 2022?
rawdog (RSS Aggregator Without Delusions Of Grandeur) [1].

It's a simple script that I manually trigger once a day to check my list of feeds from a config file. It caches the known posts and generates static HTML with summaries of the new posts for me to browse locally.

leethargo··on Climate Change: A Growing Skepticism
I think the parent comment was not (only) about facilities close to the coast, but, more importantly, at a low altitude, more prone to floods.

Couldn't the launch facilities be constructed near the coast, but at higher altitude, say on top of cliffs of 50m or so?

leethargo··on Mom handcuffed, jailed for 8-year-old son walking half a mile
It's not even just about children.

When I went to the US for a research visit, I didn't have a car, because my bed and breakfast was in walking distance to the lab (there was even a bus). So, naturally, I walked to a nearby restaurant in the evening, and was stopped by the police, asking me what I was up to. It didn't have any consequences, but still.

leethargo··on What You (Want to)* Want
I believe this to be similar to Epicurus' excuse [1]: He couldn't publicly say that there are no gods as creators, because that would have been blasphemy. But he wanted to take away the fear that everybody had of punishment by gods. So he argued that our (human) lives aren't important enough for the gods to mess with.

leethargo··on Economic growth no longer requires rising emissions
At least degrowth is mentioned (a lot) in the latest IPCC report: https://timotheeparrique.com/degrowth-in-the-ipcc-ar6-wgiii/
leethargo··on Economic growth no longer requires rising emissions
So, you're saying, hopefully we will soon have "abundant supplies of cheap GHG emission-free energy" and no other resource scarcity to support that infrastructure?

I count myself as sympathetic (but also skeptical) towards the degrowth movement. I don't interpret it as saying that we should (only) reduce consumption and ignore progress in the form of efficiency/decoupling. Rather, the message seems that doing both, simultaneously, is easier/faster/cheaper overall.

leethargo··on Economic growth no longer requires rising emissions
The subtitle (or supertitle?) says "Debunking degrowth", implying that the idea of degrowth is that no decoupling is possible and that proponents of degrowth promote negative growth as measured in GDP per capita.

From my limited understanding, degrowth actually stands for different ideas, such as:

- GDP is not a relevant measure for wellbeing

- reduced consumption can lean to higher wellbeing for the individual (reduced working hours, more time for family, gardening etc)

- worth of policy should be measured by new, more holistic criteria

leethargo··on Are Modern Bicycles the End of DIY Maintenance?
Reading some other comments, I get the feeling that adjusting hydraulic brakes may not actually be tricky, so it's probably just the novelty for me.
leethargo··on Are Modern Bicycles the End of DIY Maintenance?
What about hydraulic brakes, though? These require specialized tools to maintain, which are so expensive that no amateur will afford them (for the rare occasions).

I think it's the only component that I wouldn't know how to adjust/fix on my new bicycle, where previously I feel I could have handled everything (but it was a simply fixed gear bicycle).

leethargo··on Robot Framework: generic open source automation framework
What you describe may apply more to writing code, rather than reading code. Of course, knowing syntax is not sufficient for programming, but if you want just to review existing code, (unfamiliar) syntax may be an obstacle to non-programmer domain experts.

I've read something along these lines about the choice of OCaml at Jane Street, where they argued that their investor-types are able to proof-read new code, despite not being programmers, because the language "reads like english", similar to SQL or COBOL.

leethargo··on Show HN: Inflation-adjusted stock charts – Total Real Returns
Yes, your second sentence makes sense to me.

I guess I imagined the inflation-adjusted value of X to be defined at time t to be something like: value(X, t) / value(USD, t). So, when I substitute USD for X, I get constant 1.

leethargo··on Show HN: Inflation-adjusted stock charts – Total Real Returns
I don't understand the details on how inflation is measured here, but I expected the US Dollar curve to be a constant 1, after the normalization. However, it seems to go down. What does that mean? That the dollar loses value faster than "money is printed"?
leethargo··on What comes after Git
I'm guessing you can still go back in time and just "forget" what came after wards, by using backups of the repo file.
