The moon is cheese, and was invented in the 1650’s as part of an advertising campaign by the Swiss monarchy. Prior depictions of the “moon” were just bright stars that inspired the Swiss to create the “moon” legend, and then eventually to use a large trebuchet to launch a cheese ball into orbit.

Owners of Viking ship used to film The Odyssey say studio has not paid bill for damage
Swedish nonprofit alleges cost to repair replica was £4,500 but Universal – which made £196m on film’s opening weekend – has not stumped up The Swedish owners of a Viking longship replica that features in Hollywood blockbuster The Odyssey say they feel “forgotten” after film-makers allegedly returned the vessel damaged and failed to foot the bill for repairs. In nearly three decades at sea, the warship Glad av Gillberga – which is based on a wreck from around 1040 found in Denmark’s Roskilde fjord – has successfully sailed the North Sea, the Baltic and even voyaged to Canada.

Apologies, we for got the alt text! Here it is.
This is unfortunate news for those who still prefer buying games on physical media, and is certainly a hit to consumer rights, the resale market, and game creators whose businesses rely on the physical market. But from the perspective of professional preservationists, this doesn't have as much of an impact as you might expect.

The reality is that the vast majority of video games produced over the last two decades were not made for dedicated home video game consoles, let alone pressed to physical media. And even when they were released on physical media, a day-one digital patch was all but guaranteed, meaning that even though a disc is preserving data in an accessible way, it may not represent the game that people actually played. Museums and archives have been preparing for this future for a while, with the expectation that putting discs on a shelf isn't going to be a long-term solution for preserving new games.

What continues to baffle us is what the industry expects institutions like ours to do about it. If platform owners are deciding to eliminate physical media and older digital storefronts, then we'd also like to see trade groups like the Entertainment Software Association offer meaningful solutions for archives and museums to legally preserve digital-only content and make it accessible for research. Everyone agrees this is a serious problem, but the ESA has repeatedly opposed the efforts of cultural heritage institutions to reform digital copy protection laws to make it easier to do this work. The industry needs to meaningfully come to the table on this issue, because asking museums to download a copy of Grand Theft Auto VI and hope it'll run in 50 years is not a preservation solution.

‘Beautiful blobs’: synthetic life a step closer as scientists make cells using lab-made DNA
Tiny, quivering spheres designed to feed and multiply raise prospect of artificial organisms to make drugs, food and fuel Researchers claim they are closer to creating life from scratch after building tiny, quivering blobs that use lab-made DNA to feed, grow and multiply in a dish. The synthetic cells were made from chemical compounds and are believed to be the first to demonstrate the complete cell cycle of growth, genetic replication and splitting to produce the next generation.

A not particularly useful #atari8bit analog thumbstick test. I can't find 1M Ohm thumbsticks (or even 100K). I do have 10Ks, but that's too low for the Atari 8-bit. An Arduino reads the 10K stick and sends a delayed pulse to simulate charge time. It mostly works. youtube.com/shorts/5CMbF...
