Divya Tyagi, a graduate student pursuing her master’s degree in aerospace engineering, completed this work as a Penn State undergraduate for her Schreyer Honors College thesis. Her research was published in Wind Energy Science.
“I created an addendum to Glauert’s problem which determines the optimal aerodynamic performance of a wind turbine by solving for the ideal flow conditions for a turbine in order to maximize its power output,” said Tyagi, who earned her bachelor’s degree in aerospace engineering.

No. You can't tell it was written by AI by Segun Famisa.
In this essay, I will argue that, your favourite “tells” that a document was produced by AI, at best, is wrong, and depending on your position, in life, at worst, is dangerous and harmful.[...]
So who trained [AI]? A lot of the early training, data annotations and other manual processes, happened with cheap labour in African countries. There are multiple sources that have revealed the hidden economy of workers that big-tech outsources these kinds of tasks to African countries with unstable political situations, weaker workers rights, and cheap labour.
Curious about how LLM's actually work? So What's The Next Word Then? by Matthias Kainer does a good job of explaining it, with diagrams. Via Martin Fowler's blog.
Acting ethically in an imperfect world by Jürgen Geuter describes and addresses Cory Doctorow's defensiveness about using LLMs.
I appreciate a lot of work Cory Doctorow has done in the last decades. But the arguments he presents here to defend his usage of LLMs for this rather trivial task (which TBH could probably be done reasonably well with traditional means) are part of why the Internet – and therefore the world – looks like it does right now. It’s a set of arguments that wants to delegitimize political and moral actions based on libertarian and utilitarian thinking.
GenAI has an Alignment Problem by Richard George.
But the mundane reality is much simpler: LLMs fail to effectively solve the problems we have, while creating a vast new class of problems to be solved. They are, ultimately, completely mis-aligned with our needs, and incompatible with the society we live in.
Relatedly, why AI isn't actually helping software companies. Dax Raad just dropped the most honest take on AI productivity written up by JP Caparas.
everyone's talking about their teams like they were at the peak of efficiency and bottlenecked by ability to produce code
here's what things actually look like:
- your org rarely has good ideas. ideas being expensive to implement was actually helping
- majority of workers have no reason to be super motivated, they want to do their 9-5 and get back to their life
- they're not using AI to be 10x more effective they're using it to churn out their tasks with less energy spend
- the 2 people on your team that actually tried are now flattened by the slop code everyone is producing, they will quit soon
- even when you produce work faster you're still bottlenecked by bureaucracy and the dozen other realities of shipping something real
- your CFO is like what do you mean each engineer now costs $2000 extra per month in LLM bills"

A programmer's loss of identity by Dave Gauer.
The social group I still identify with shares my values. We value learning. We value the merits of language design, type systems, software maintenance, levels of abstraction, and yeah, if I’m honest, minute syntactical differences, the color of the bike shed, and the best way to get that perfectly smooth shave on a yak. I’m not sure what we’re called now, "heirloom programmers"?"Acoustic" programmers (like guitars)? "Thought-powered" programmers (like gas-powered cars)? I'm not ready to be an heirloom yet!

Somehow it's the drummer who impressed me the most. Which instrument do you think would be the hardest to play on skates?
- I use slippery floss because my teeth are closely spaced, so I need to wrap around the posts 5 times rather than 3. It is also easier if there's a tail on each side, so I use about 9 inches of floss (the length of the FlossGrip plus a couple inches) each time. This is about half of what I used with just my fingers.
- It's easier to wrap the floss with dry hands, before I brush my teeth.
- The FlossGrip is embossed on one side with "FlossGrip", which makes it easier to keep track of which post I wrapped first, for unwrapping.
- The little slots that lock in the floss are compressed by wrapping the floss around the posts, which means there is a just-right tension that lets the floss slide in, and then holds it securely.
- It helps to angle the FlossGrip to match the actual angle of each gap between my teeth, not what I imagine the angle to be.
- It also helps to minimize the pressure I use to get down into each gap, so I don't irritate my gums.
So that's it, what a geeky person thinks about while flossing her teeth.

In an abandoned cemetery on Cuba’s Isla de la Juventud stands the weathered headstone of Estefania Koenig. When she died in 1981, at the ripe old age of 95, she was the last American of what had once been called the McKinley Colonies. A century ago, it was a thriving citrus-growing community, American in everything except the letter of the law. Then came a couple of devastating hurricanes — and the closure of a geopolitical loophole.
A forgotten footnote in American history
The story of the McKinley Colonies is more than a forgotten footnote in history. William McKinley, the 25th president of the United States (from 1897 until his assassination in 1901), was America’s last unabashed expansionist-in-chief. Under his watch, the U.S. snapped up Guam, the Philippines, Puerto Rico, and Cuba from Spain (with full sovereignty over the former three and only temporary control over the latter).
McKinley matters today because the current occupant of the White House is a fan: Trump name-checked him in his second inaugural address, and his own musings about acquiring the Panama Canal, Canada, and Greenland suggest an urge to outdo McKinley’s territorial haul. Yet as the failed Cuban experiment shows, reality has a way of trumping even the most bullish dreams — pun very much intended.
At 934 square miles (2,419 km2), Isla de la Juventud is slightly smaller than Rhode Island, yet still the seventh-largest landmass in the Caribbean. It’s twice the size of Martinique, but with just over 80,000 inhabitants, it has barely one-fifth of its population. It lies just 29 miles (47 km) off Cuba’s southwest coast across the shallow Gulf of Batabanó — so shallow that a healthy cow could swim across at low tide, a rather unorthodox legal argument for Cuban ownership once claimed.
The Island of the 500 Murders
Over the centuries, the island has had many identities and many names: Siguanea, Camaraco, or Ahoa to indigenous groups; La Evangelista to Columbus, who sighted it on his second voyage to the New World in 1494; Parrot Island for its flamboyant birdlife; and Treasure Island for its popularity as a pirate hideout. (It is rumored to have inspired Robert Louis Stevenson’s eponymous adventure story.)
In the 20th century, it acquired grimmer monikers — Island of the Deported, Island of the 500 Murders — after the opening of the notorious Presidio Modelo prison. Its most enduring name throughout the centuries, however, was Isle of Pines — until Fidel Castro rebranded it Isle of Youth in 1978.
Under Spanish rule, the Isle of Pines was barely governed and thinly populated. The 1864 census tallied just 2,000 souls. The plot twist came after the 1898 Treaty of Paris, which ended the Spanish-American War.
Article I of the treaty handed Cuba over to U.S. oversight with the promise of eventual independence. Article II, however, granted the U.S. full sovereignty over Puerto Rico and “other islands” in the West Indies formerly held by Spain. Was the Isle of Pines, far larger and more distant than Cuba’s minor keys, one of those “other islands”?
The swimming-cow faction said no. The New York Times, too, scoffed at the idea, comparing the idea to exempting Long Island from U.S. treaties or Ireland from the U.K. (the latter comparison hasn’t aged well, to say the least).
But U.S. land promoters said yes — and loudly. In 1901, they helped ram the Platt Amendment through Congress; later embedded in Cuba’s constitution, it left the island’s status “to future adjustment by treaty,” conveniently excluding it from Cuba’s new boundaries. Cue the land rush!
Manifest Destiny rebooted
Glossy brochures billed the place as a “Veritable Garden of Eden.” (Fine print: Hurricanes? What hurricanes?) With the Wild West frontier officially closed in 1890, this was Manifest Destiny rebooted — with palm trees substituting for sagebrush. Citrus beckoned: The soil and climate were ideal, and access to American markets was easy.
American investors and settlers flooded in. In 1900, just 10 Yanks lived on the Isle of Pines. A decade later, up to 5,000 had bought plots and around 2,000 had settled permanently — effectively doubling the island’s population.
Land companies scooped up vast tracts on the cheap from locals, subdivided them into neat grids, and flipped them at a tidy profit. They were bought by Americans eager to try a sunnier version of capitalism among the orange trees. Colonies popped up by the dozen, mostly in the north. (The swampy center and rocky south stayed stubbornly unproductive.)
Founded in 1902, Columbia was one of the first American towns. Eight years later, it had a hotel, general store, school, post office, and a wharf on the Jucaro River. Also in 1902, colonists from Buffalo founded McKinley, a not-so-subtle appeal to the expansionism of the president assassinated the previous year at the Pan-American Exposition in their hometown. The town would sprout an East and West McKinley and lend its name to the broader McKinley Colonies.
“American ministers preach from Protestant pulpits”
Other American outposts followed. Santa Barbara featured Nordic-style houses and, improbably, an art gallery. Los Indios became the nucleus of a burgeoning citrus empire, with a direct connection to New York. Even Nueva Gerona, the old Spanish center, acquired an Old Virginia Café and an American Club. Settlers read their own newspaper, The Isle of Pines Appeal.
By 1910, as author I.A. Wright observed, Americans were in the majority on the island:
“American money is not only the official but the actual currency of trade; the prevailing architecture outside the towns is American; American ministers preach from Protestant pulpits; American teachers preside over schools where American children congregate, and these schools are conducted in English.”
“American spring wagons and automobiles have replaced the clumsy ox-cart and the picturesque coach, and they travel over the best of roads — wide, smooth highways, which facilitate shipments of fruits from orchards and gardens owned by Americans, producing for American markets. It is literally true that Americans own the Isle of Pines. Not two per cent of its area is the property of persons of other nationality.”
That sounds just about right. Another source states that, by 1925, Americans owned between 90% and 95% of the island, turning it into citrus central. One booster even published a 250-recipe cookbook for pineapples and grapefruit — as if gastronomic versatility was an argument for annexation.
Optimists foresaw the full and swift Americanization of the island, de jure as well as de facto. But there was trouble in paradise. The devastating hurricanes of 1917 and 1926 didn’t read the brochures. America’s entry into World War I in 1917 diverted attention — and fertilizer — from the island. Many settlers lacked capital, know-how of tropical farming, or both.
A two-decade “slumber” in the Senate
Worst of all, the Hay-Quesada Treaty of 1903, which had “slumbered” in the U.S. Senate for over two decades, was finally ratified in 1925, confirming Cuban sovereignty over the Isle of Pines and slamming the annexation door shut.
The American dream withered. Most would-be colonists left. From its peak of about 2,000 settlers, the island’s American population plummeted to 276 in 1931, and just 150 year-rounders by 1942. Citrus acreage shrank from 4,000 to 1,000; ownership shifted to Brits and Canadians. A small but active Japanese colony became very successful in vegetable-growing.
A brief revival came in the 1950s under the dictatorship of Fulgencio Batista, who offered tax breaks to promote tourism on the island, which contrasted favorably with the vice, crime, and anti-Americanism of Havana and other hotspots on the Cuban mainland. But then came Castro.
In the mid-1950s, when they were still revolutionaries fighting Batista, Fidel Castro and his brother Raúl had done time in the Presidio Modelo, a panopticon prison for political enemies of the regime. After they ousted Batista in 1959, the Castros kept a close interest in the island, remaking it with youth camps, schools, and farms, and ultimately renaming it.
Lessons for Donald Trump
As with the rest of Cuba, what remained of American interests on the island was nationalized. By 1961, there were just 35 Americans left. By 1971, just one.
President McKinley, as adept at raising tariffs as at raising flags, is an obvious example for his current successor. But do the failed McKinley Colonies hold any lessons for Donald Trump?
Perhaps just this: Hype, hubris, and aggressive land grabs can redraw a map for a while. But geopolitical reality tends to catch up, as evidenced by those forgotten headstones in the Cementerio Americano.
Still, if recent patterns hold, one of these nights President Trump will tweet about that old Yankee grapefruit grove just off Cuba’s coast, declare it “rightfully American,” and demand an urgent return to its proper owners. Trump Colonies? It does have a certain ring to it …
