“This bread is straight from Jerusalem!” was stated at least 5 times during our stay and it could be felt how significant this was to him. Even in Palestine the bread is unique to the city, travelers from other parts buy many loaves to bring as gifts to their friends and family. The crust is soft and covered in sesame seeds, the bread inside even softer and so light. Despite being almost 1 meter long before cutting, it is not heavy and feels like it might float away.

Chain Letter Evolution
Apocryphal letters claiming divine origin circulated for centuries in Europe. After 1900, shorter more secular letters appeared in the US that promised good luck if copies were distributed and bad luck if not. Billions of these “luck chain letters” circulated in the next 100 years. As they replicated through the decades, some accumulated copying errors, offhand comments, and calculated innovations that helped them prevail in the competition with other chain letters.
Against key-value stores
Fast key-value stores, an idea whose time has come and gone
In ProtoCache, replacing the RInK with stateful application servers resulted in a 29-57% median latency improvement and 40%+ reduction in CPU.
Mars Geology
This week’s map is an artistic rendition of the geologic map of Mars designed by the USGS. I used the same geology data as the original map, but I added more topographic and label data, redesigned the visual style, and also edited the key for a more general audience. One of the most difficult parts of making this map was translating the key into plain English. The original USGS map was designed for geologists, so I had to look up almost all of the vocabulary. For example, my abbreviated definition for a caldera rim was “The rim of an empty magma chamber left behind after a volcanic eruption.” The original description was “Ovoid scarp, outlines single or multiple coalesced partial to fully enclosed depression(s); volcanic collapse, related to effusive and possibly explosive eruptions.”

Forecasting Progress
In 2015, the 6 day forecast was as good as its 3 day forecast was in 1975. In 2012, its computers correctly foresaw Hurricane Sandy at least 6 days in advance. By 2025, they are expected to be able to detect high-impact events 2 weeks into the future.
Moon Metals
Metal 5x larger than the Big Island of Hawaii has been discovered beneath the largest crater on the Moon, the South Pole-Aitken basin. It would make lunar colonization and the industrial development of space far easier.
Rent-Stabilized EV
Requests for visual descriptions yielded memories of “that old kind of toilet with the oak box,” rooms that were “all rhomboids,” and “the roaches.” Asked what they liked about their place, tenants mentioned “the cross-ventilation,” “the exposed brick,” and “the fact that the bathroom is now in the apartment.” Schiffman elicits stories from people who are both dreading a prospective rent hike and reconsidering the decision to keep a “Mao room.” A neighborhood blog, EV Grieve, runs the answers once a month, along with Schiffman’s photos.
What the Celts drank
Our analyses confirm that they indeed consumed imported wines, but they also drank local beer from the Greek drinking bowls. In other words, the Celts did not simply adopt foreign traditions in their original form. Instead, they used the imported vessels and products in their own ways and for their own purposes. Moreover, the consumption of imported wine was apparently not confined to the upper echelons of society. Craftsmen too had access to wine, and the evidence suggests that they possibly used it for cooking, while the elites quaffed it in the course of their drinking parties
Planet-Saving Robots?
Between robotics and nanotechnology, we could clean up the planet significantly, if not totally, in 10 years
Totally not robots
If Only Turing Was Alive To See This
There’s a silly subreddit called r/totallynotrobots where people pretend to be badly-disguised robots. They post cat pictures with captions like “SINCE I AM A HUMAN, THIS SMALL FELINE GENERATES POSITIVE EMOTIONS IN MY CARBON-BASED BRAIN” or something like that. There’s another subreddit called r/SubSimulatorGPT2, that trains GPT-2 on various subreddits to create imitations of their output. Now r/SubSimulatorGPT2 has gotten to r/totallynotrobots, which means we get to see a robot pretending to be a human pretending to be a robot pretending to be a human.
