I Built a Stable Planetary System with 416 Planets in the Habitable Zone
This system is completely stable—I double-checked with computer simulations. But nature would have a tough time forming this system. If it exists, it could only have been built by a super-advanced civilization. That’s why I call it the Ultimate Engineered Solar System.

Imagine the stories you could tell in these Ultimate Solar Systems! Each binary planet has a close neighbor hovering larger than the moon in the sky. The night sky has an amazing wealth of wandering stars, the other planets traci...

Programming by poking: why MIT stopped teaching SICP | posterior science
Sussman said that in the 80s and 90s, engineers built complex systems by combining simple and well-understood parts. The goal of SICP was to provide the abstraction language for reasoning about such systems.

Today, this is no longer the case. Sussman pointed out that engineers now routinely write code for complicated hardware that they don’t fully understand (and often can’t understand because of trade secrecy.) The same is true at the software level, since programming environments consist of gigantic libraries with enormous functionality. According to Sussman, his students spend most of their time reading manuals for these libraries to figure out how to stitch them together to get a job done. He said that programming today is “More like science. You grab this piece of library and you poke at it. You write programs that poke it and see what it does. And you say, ‘Can I tweak it to do the thing I want?'”. The “analysis-by-synthesis” view of SICP — where you build a larger system out of smaller, simple parts — became irrelevant. Nowadays, we do programming by poking.

296 - The Dykes of Doggerland | Big Think
If the extensive schemes for the drainage of North Sea are carried out according to the plan illustrated above, which was conceived by a group of eminent English scientists, 100,000 square miles will be added to the overcrowded continents of Europe. The reclaimed land will be walled in with enormous dykes, similar to the Netherland dykes, to protect it from the sea, and the various rivers flowing into the North Sea will have their courses diverted to different outlets by means of canals.

Bagger 288 - Wikipedia, the free encyclopedia
When its construction was completed in 1978, Bagger 288 superseded NASA's Crawler-Transporter, used to carry the Space Shuttle and Apollo Saturn V launch vehicle, as the largest land vehicle in the world. It is 311 feet tall and 705 feet long.[1] It weighs 45,500 tons, which makes it heavier than RMS Titanic.

Man, stranded in the desert, makes a motorcycle from his broken car - Hack a Day
While traveling through the desert somewhere in north west Africa in his Citroen 2CV , [Emile] is stopped, and told not to go any further due to some military conflicts in the area. Not wanting to actually listen to this advice, he decides to loop around, through the desert, to circumvent this roadblock.

After a while of treading off the beaten path, [Emile] manages to snap a swing arm on his vehicle, leaving him stranded. He decided that the best course of action was to disassemble his vehicle and construct a motorcycle from the parts. This feat would be impressive on its own, but remember, he’s still in the desert and un-prepared. If we’re reading this correctly, he managed to drill holes by bending metal and sawing at it, then un-bending it to be flat again.

Phonograph - Wikipedia, the free encyclopedia
In December, 1877, a young man came into the office of the SCIENTIFIC AMERICAN, and placed before the editors a small, simple machine about which very few preliminary remarks were offered. The visitor without any ceremony whatever turned the crank, and to the astonishment of all present the machine said : " Good morning. How do you do? How do you like the phonograph?" The machine thus spoke for itself, and made known the fact that it was the phonograph..."

Diseased disciplines: the strange case of the inverted chart
The original claim was that "defects introduced in early phases cost more to fix the later they are detected". The misquoted chart says this instead: "defects detected in the operations phase (once software is in the field) cost more to fix the earlier they were introduced".
