how to cut a mango

I need a break from doom and gloom, so why not how to cut a mango? This is a useful life skill, and not one this typical white bread mainstream American learned growing up. I also like that she is showing the Asian mangos (which I see marketed as “champagne” mangos) rather than the Mexican ones we more typically see in the US. These can be prohibitively expensive in your typical chain grocery store, if you see them at all. My guess is they don’t ship as well and they just aren’t as pretty to look at on the outside. The place to look for them is an Asian grocery if your city has one. Look for a big box that at first glance might contain rotten potatoes, and you will be on the right track.

By the way, I looked it up and the plural of mango is…either mangos or mangoes. Mangoes is a bit more popular, but both are acceptable.

And lastly a travel tip. If you ever find yourself traveling in a tropical country and want to make small talk, don’t bother about the weather. It’s hot. Everybody knows it’s hot, it’s always hot and it’s always going to be hot. But people generally love to talk about tropical fruit, so it’s a good ice breaker. And nobody ever got disappeared by the local gestapo for talking about fruit, that I know of. Well, bananas and coconuts, maybe…

the US “R&D ecosystem”

This article from “chinatalk.media” (which I know nothing about) explains how the US R&D pipeline has always been a partnership between universities, the private sector (including, in some cases, closely regulated monopolies like Bell Labs), and the government. It has been the envy of the world and emulated by others, including by China. Basically, the federal government funds basic research through universities that there is not a clear market for yet. In some cases, it creates a market through its procurement ability which incentivizes the private sector to take the risk of taking nascent scientific breakthroughs from the universities and bring them to market.

To better understand today’s landscape, we need to trace our steps back about 70 years and examine how the American research ecosystem was conceptualized. The original model positioned universities to conduct curiosity-driven research funded by the federal government, while American industry focused on transforming that research into applications.

There were certain industrial monopolies created by the government that also conducted basic research, which Alex can address more comprehensively. However, the overwhelming majority of basic research happened in academia — universities created as land-grant institutions or those existing before the war. This system served us remarkably well, as basic research developments from the 1950s, 60s, and 70s bore fruit 10, 20, 30, or 40 years later. The nature of basic research doesn’t necessarily have an immediate application, but applications may emerge years down the line.

Agencies like the National Institutes of Health fund more applied research on medicines and can point to tangible outcomes — specific drugs developed with NIH funding. The NSF, conversely, funds basic research that may not demonstrate tangible benefits for decades, as happened with neural networks.

What madman claiming to love our country would try to break this? He would have to be either extremely ignorant or a traitor to our country.

more on India-Pakistan water sharing

I will refrain from commenting on fast-moving current events in the India-Pakistan conflict. But here is a bit more on the water situation bubbling (sorry) under the surface (sorry again).

From an opinion piece by Brahma Chellany (“Professor Emeritus of Strategic Studies at the New Delhi-based Center for Policy Research and Fellow at the Robert Bosch Academy in Berlin, is the author of nine books, including Water: Asia’s New Battleground (Georgetown University Press, 2011), for which he won the 2012 Asia Society Bernard Schwartz Book Award.”)

“But this time, Modi has offered a calibrated and impactful response, pausing the Indus Waters Treaty (IWT), the world’s most-generous water-sharing pact, which grants downstream Pakistan access to over 80% of the Indus Basin waters. Brokered in 1960 by the World Bank, the IWT has long been hailed as a model of cross-border cooperation – one that China has not emulated. (Though its 1951 annexation of the water-rich Tibetan Plateau gave it control over the headwaters of Asia’s major rivers, China has refused to enter into a water-sharing treaty with any of its 18 downstream neighbors.)” …

Last year, when India formally sought to update the IWT – to account for unanticipated factors like climate change, groundwater depletion, and population growth – Pakistan refused to negotiate. [Note this is clearly an opinion and not an objective discussion, I am sharing as an example of how someone sympathizing with the Indian side might view the issue.]

Now a discussion of some science from indianexpress.com (which I have no past experience or inside information about, but it passes my surface credibility instincts):

Kulkarni said studies carried out by him and his colleagues have shown that the glaciers feeding the Ravi, Sutlej and Beas rivers, located at a lower altitude, are retreating at a faster rate in comparison to the glaciers in Pakistan, located at high altitudes in the Karakoram range. As a result, the amount of glacial meltwater is projected to be much higher than the previous decades till the middle of the century, which would be followed by a significant reduction in water availability, he said.

“The glaciers located on the eastern side are located at a relatively lower altitude, and they are losing mass at a higher rate, thus retreating faster. As you go higher, in the Karakoram mountain ranges, glaciers are not losing mass, they are relatively stable. In the scientific community, it is called the Karakoram anomaly,” said Kulkarni, a scientist at the Divecha Centre for Climate Change, Indian Institute of Science, Bengaluru

Under the IWT, signed in September 1960, all waters of the Indus basin’s eastern rivers — Satluj, Beas and Ravi — are available to India for unrestricted use. Pakistan has rights over the western rivers — Indus, Jhelum and Chenab — and being upstream of its neighbour, it can only use waters of these rivers for non-consumptive use, such as to produce hydropower, navigation, flood protection and control, and fishing.

So the glaciers in the headwaters controlled by India have more flow currently because the glaciers there are melting faster, but there is less water stored there than in the headwaters controlled by Pakistan, and that would mean less flow in the future. Somewhat counter-intuitive. It also never occurred to me that China’s occupation of Tibet could be at least partly about controlling Himalayan headwaters. It’s hard to believe any of these countries and their politicians are making policy decisions based on long-term scientific forecasting and thinking. But maybe they are actually more rational and scientifically oriented than at least our current cohort of irrational and scientifically illiterate U.S. politicians.

from the somewhat fun, scientifically illiterate movie 2012, in which the Himalayas are flooded by more water than exists on Earth

don’t ruin Tolkien for me, assholes

I read the Lord of the Rings in approximately middle school (the late 1980s), and I am rereading it with my son now. It’s wonderful. Now, I think it is amazing that there are people called “Tolkien scholars”, and I am a fan of scholarship in general. But really, let’s not ruin Tolkien by overthinking it like this:

The Lord of the Rings seems immersed in racism (the superiority of the fair and noble elves, the inferiority of the brutish, mongrel orcs), colonialism and imperialism (the return of the king means the restoration of empire), and deeply retrograde sexism (with a core cast of characters that is overwhelmingly male). There is also a generalized suspicion of democracy, cities, modernization, progress, cultural relativism, and materialism in favor of monarchism, agrarianism, stasis, fantasies of good versus evil, and a traditionalism that at times borders on religious fundamentalism (Tolkien himself was a pre–Vatican II Catholic). The Lord of the Rings is a series obsessed with ruins, bloodlines, the divine right of aristocrats, and a sense of history as a tragic, endless fall from grace.

I don’t take it this way, actually. The world of the Lord of the Rings is a simpler world where there is a clear dichotomy between pure good and pure evil. I think this is what Tolkien wanted to explore – essentially the “why do bad things happen to good people” problem. The answer to this question was clear in Middle Earth – because there are evil supernatural beings out there who are the source of all bad things, there is a constant push and pull between good and evil, and sometimes evil gets the upper hand. (There is a supreme being or god in the Tolkien universe, who seems to have intentionally created good and evil, and there is some mystery as to why. Tolkien was religious and probably wanted to wrestle with this question in his own way.) Orcs and trolls are just evil minions created by these evil supernatural beings. It is their nature to be evil and they are not deserving of our sympathy. I think he was well aware that this sharp dividing line does not exist in our real world. In fact, among all the “races” he invented, it is the humans alone who seem ambiguous in terms of being capable of both good and evil. So this sounds like our real world. And at the end of the Lord of the Rings, and especially if you read the Silmarillion, Tolkien transitions from the fantasy world back to our real world.

Maybe I’ll get into the “fair” elves and comical Scottish dwarves at some point, because although I like the movies I don’t think the way these “races” are portrayed are true to the books, or at best they are just one possible interpretation.

Pakistan Nuclear Policy

An interesting snippet on Pakistan’s nuclear policy (from indianpunchline.com, which I have no prior experience with):

Pakistan’s nuclear doctrine allows for first strike if the nation’s survival is deemed to be under thereat. Three thresholds have been spelt out: denial of water flow into Pakistan (under the Indus Waters Treaty); any naval blockade; and foreign occupation of Pakistani territory. 

India has unilaterally suspended the Indus Waters Treaty. I have however seen articles arguing that they do not have the technical ability to deny water flow on a significant scale. Still, even if this is all just talk at the moment, it is a step down a dangerous path for the region and the world.

Being fairly ignorant of geography, I had to review how much coastline Pakistan actually has. And it does in fact have a substantial coastline on the Arabian Sea/Indian Ocean, with a Karachi as a major coastal city.

April 2025 in Review

Most frightening and/or depressing story: Maybe an irreversible methane tipping point is happening. This could be the scariest thing out there short of nuclear war.

Most hopeful story: 3-30-300 is a nice, simple idea. “you can see 3 trees from your window, your neighborhood has 30% tree canopy cover, and you are within 300 m of a half-hectare park.” Sure, you have to figure out some details and make some sustained effort over time to implement simple ideas. Still, not rocket science. Combined with the “15 minute city”, this is a pretty good urban planning philosophy that should be communicable.

Most interesting story, that was not particularly frightening or hopeful, or perhaps was a mixture of both: I made what I would consider a “common sense” trade policy proposal. “I generally support…free trade. But if we are going to trade freely, we need a safety net for people who are hurt. We could do this with generous unemployment benefits and retraining programs. We could help people relocate to places with jobs. We could provide much better communication and transportation infrastructure allowing them to commute regionally to places with jobs. We could educate their children so they are prepared for the jobs of tomorrow. We could institute a value added tax on our productive, growing economy and use it to provide services or cash to workers. We could invest even more in research and development to make our economy even more productive and growing. We could invest in neighboring countries to help them be more productive and growing, import cheap stuff from them, and reduce some of the migration pressure on our borders.”

My Keys to Happiness in the Moment

I’ve been thinking about this, whether there is any recipe for my personal happiness in the moment. Happiness in the moment is something different from overall life satisfaction, maybe a topic for another day. Anyway, here is what I have come up with.

  1. Sleep. Enough sleep, and quality sleep. I’ve always had some trouble falling asleep and staying asleep, and I don’t have all the answers. Keeping a set routine most of the time, including weekends, helps. Winding down for an hour or so before bed helps (not always under my control with the life of a working parent). Podcasts and audio books can help for those nights when the mind just doesn’t want to settle down. A quiet, dark, cool bedroom and comfortable bed help (again, not always under my control, although I have taken to sleeping with earplugs at times.)
  2. Coffee. Surprising to see this at #2? For me it’s the only 100% reliable antidepressant out there. I often wake up feeling like the world is not such a nice place, and 30-60 minutes after I have my coffee, it feels like a much nicer place. More coffee is not better, of course. 1-2 cups, at about the same time each day, works for me.
  3. Exercise. Anything including stretching or a walk can provide a temporary mood pickup, but consistent exercise several days in a row really seems to improve my mood. It doesn’t have to be long – maybe 20-30 minutes – but it does have to involve some heart pumping, heavy breathing, sweat and/or sore muscles to maximize this effect for me. Part of the effect of exercise may be that it reinforces good sleep.
  4. Down time. I think the introvert/extrovert framework is a useful way to think here. For extroverts, spending time with friends and family may count as down time. For me, it does not. I love my friends and family, and I don’t want to live my life in solitary confinement, but for me some alone time is non-negotiable to feel my best. Reading, thinking, ideally some time in nature or at least outdoors. Ideally it would be at least an hour a day, a day a week, and a weekend each month. The latter two have been impossible in middle aged working professional family life, but I grab the alone hours and moments where I can. I know however that my mental health is never what it could be if I could slow down and have more time to myself. Perhaps if I live long enough to retire…but it’s sad to look forward to the later stages of your life. Such is the supposedly modern world we have created for ourselves.

That’s it! There are many other things that might help at the margins. Good nutrition certainly. Meditation. Power naps. I do not oppose the light recreational use of alcohol and possibly other substances, in particular to enhance that down time that is in such short supply. And of course professional help is out there and worth trying for many people. I’m sure I could come up with a long list here. But none help that much without nailing the top 4.

Finally, it helps me to think of high and low moods as being like the weather. High and low moods will come and go. Sometimes there is no obvious reason for them. You can’t predict them with certainty, and you can’t expect to control them all the time even if you do everything perfectly. Following the “Top 4” things above improves the odds considerably I think, but there will still be bad days and occasionally weeks. So on those emotional “rainy days”, it is okay to slow down a bit and just remind yourself that the bad weather will pass.

Roundabouts

Roundabouts are not really cutting edge, but they are new to many of us in the slow-on-the-uptake Commonwealth of Pennsylvania. Here’s a video on what you are supposed to do.

Youtube

One thing drivers are NEVER supposed to do is pass a bicyclist in the lane, in a roundabout or anywhere else. I observe that most drivers and bicyclists are confused about this. Not only do bicyclists often hug the right edge of the lane, drivers tend to speed up as they pass them, which is going to be deadly if anything unexpected happens. Under our state law, cars have to give bikes 4 feet of space. Lanes are around 12 feet wide, so this means a car centered in the lane cannot physically pass a bike legally. Police do not enforce this rule, and signs stating it are very rare. We occasionally see the “BIKES MAY USE FULL LANE” sign, but a better sign, which I have seen in other states, adds “CHANGE LANES TO PASS”. Separated, protected lanes for low-momentum zero emissions vehicles with their own signals at intersections would be the superior, most modern way to go, of course.

heart attacks in young people linked to Covid-19 (era drug abuse)

At least one cardiologist thinks the documented increase in heart attacks among younger people since Covid is due not to Covid infection itself, but due to abuse of Adderall and Ritalin that picked up around that time. Sleazy online doctors are writing these prescriptions apparently. It’s sort of a hidden, slow motion version of the opioid/fentanyl epidemic because stimulants don’t cause your heart to just stop beating, they just raise the risk that it will explode over time. By the way, I’ve been listening to Donald Trump Jr.’s podcast occasionally because it is a good gauge of MAGA propaganda. The first sponsor he mentioned last time I tuned in was a sleazy online pharmacy.

This also reminds me of the book Blitzed: Drugs in Nazi Germany which is about massive methamphetamine abuse by German soldiers and civilians at the time.

As I write this I have been popping Sudafed for a couple days to try to keep a head cold from settling into my chest. It’s kind of a nice feeling. But I only bought 24 of them and when they are gone, they are gone.

Amazon

No, I’m not an Amazon associate. I’ve just noticed that posts with pictures and videos get more attention.

India cancels major water sharing agreement with Pakistan

This seems like an important story to me that has not been widely covered. There was a tragic terrorist/insurgent attack on civilians in Kashmir which was covered. But in response, India has unilaterally pulled out of a major water treaty that has been been in place for half a century. From the AP:

India also suspended a landmark water-sharing treaty that has survived two wars between the countries, in 1965 and 1971, and a major border skirmish in 1999.

The Indus Water Treaty, brokered by the World Bank in 1960, allows for sharing the waters of a river system that is a lifeline for both countries, particularly for Pakistan’s agriculture.

Pakistan has responded angrily that it has nothing to do with the attack and warned that any Indian attempt to stop or divert flow of water would be considered an “act of war” and met with “full force across the complete spectrum” of Pakistan’s national power.

I wonder if the end of the water treaty will be permanent, even after this crisis of the moment passes (assuming it does). Is it possible that the government of India was waiting for a reason to pull out of the water treaty? We have been hearing that water supplies for South Asia originating in the Himalayas are becoming less reliable, at the same time the region is becoming much hotter and the monsoon season is becoming less predictable.
