Margaret Hamilton, trailblazer whose software powered Apollo 11 moon landing, dies at 90
MIT computer scientist led development of software for moon mission and earned Presidential Medal of Freedom Margaret Hamilton, the computer pioneer whose software powered the first moon landing, has died, the Massachusetts Institute of Technology (MIT) announced on Wednesday. She was 90. In an era before titles such as software engineer and computer scientist became mainstream, Hamilton, who died on 30 September, learned to program under the tutelage of a renowned MIT meteorologist.

The current binomial was applied in 2003. AKA white dunce cap. A fairly common fungus in its native North America and Europe, growing among short green grass, but now widespread elsewhere. Wānaka, Otago, Aotearoa New Zealand.

Originally described as Agaricus apalus was described by the Swedish mycologist Elias Magnus Fries in 1818, and variously as Conocybe lactea or Conocybe albipes, Pluteolus apalu, Galera hapala, Galera apala, Bolbitius apalus and Derminus apalus in the decades since.

Endemic to the Marlborough area of the South Island. In the wild it grows on cliffs and rockfaces, in dry sunny places with low humidity. It has a reputation of being difficult to propagate, or transplant. Wānaka, Otago, Aotearoa New Zealand.

AKA Marlborough Rock Daisy, Olearia marginata and Shawia insignis - that last one is the currently accepted binomial in some sources.

The lake is the fourth largest in NZ, with a lake bed well below sea level. The shorelines are most unaltered, but Oxygen Weed (Lagarosiphon major), an invasive aquarium plant native to Southern Africa, has been a problem in the lake’s ecosystem for some time.

Unlike most of New Zealand, the climate is strongly seasonal, with warm summers, wet springs, and cold winters with frequent snowfall. Wānaka is the South Island Māori dialect pronunciation of wānanga, which means “the lore of the tohunga or priest” or a place of learning.

Sigaus grasshoppers also lack stridulatory organs, and can’t call for mates by sound. It’s also highly vulnerable to climate change - with climate warming & low dispersal potential, S. australis will probably lose 75-93% of suitable habitat by 2070. Crown Ridge nr. Queenstown, Aotearoa New Zealand.

It has a wide diet but for some reason avoids eating the abundant Snow Tussock grasses. Like all of New Zealand sub-alpine and alpine grasshoppers S. australis has a 2 or 3 years life cycle, and like most NZ grasshoppers is flightless.

The fruit - haws - can be made into jellies, jams, syrups, or wine, or used to add flavour to brandy. The young leaves and petals are also edible. - the latter in the medieval English recipe for spinee, an almond milk-based pottage. Arrow Jnc. nr. Queenstown, Aotearoa New Zealand

Back in its home range, however, it may become locally extinct from overgrazing in the next 50 years. Mature trees on the other hand are good thorny hedgerow plants, and may reach 10m in height.

Some fairy rings are huge, and ancient - one near Belfort in France is thought to have a radius of about 300 metres and to be over 700 years old. That one is made by Infundibulicybe geotropa, however, which is one of a long list of fairy ring mushrooms.

Drhoz @drhoz.bsky.social · 06/10/2026
Native to Europe and North America, but now much more widespread. Fairy rings appear (more clearly in meadows and lawns) as an expanding fungal network depletes the soil of nitrogen and starves the grass overhead.

AKA known as fairy ring champignon or Scotch bonnet, but not the only mushroom that grows into fairy rings, and some of the others are poisonous. For that matter the mushroom itself closely resembles other poisonous species, which is a shame because it’s apparently quite a tasty mushroom.

The large hill in the valley below Crown Ridge is Morven Hill, a “sheepback” hill (roche moutonnée) that somehow resisted being ground flat by the superglacier.

And then up over the Crown Ridge north of Queenstown, on a road that was only sealed in the last few years. I would have been reluctant to attempt it if it hadn’t been sealed, but driving around the mountains in NZ had me nervous at the best of times.

The rock is schist, and the megaglacier that carved it left a lakebed that’s now well below sea level. The lake used to empty to the south, but glacial deposits blocked it so thoroughly that it now drains to the NE.

Lake Wakatipu is the largest lake we passed, with Queenstown on one corner of the N-shaped lake. The etymology of the name is unclear, but Waka-tipua-wai-maori means ‘trough of fresh water where the giant lies’
