It’s Lammas Day! In the traditional rural calendar, Lammas Day signalled the annual shift from planting crops to grazing animals. It was the last day on which grass was cut for hay, and the day grazing could commence and the hunting season began. ‘The Glorious Twelfth’ – the first day for shooting grouse – is in fact Lammas Day, pushed eleven days back by the UK’s transition from the Julian calendar to the Gregorian in 1752. The right to cut hay and graze animals on certain fields extended to all parishioners, rich or poor. Such fields were known as Lammas land. Their use belonged to everyone, ‘without regard to tenement’ – meaning you didn’t have to be relatively well-off house-owner to have Lammas Rights. If this existed by long-established tradition, it was often a tradition that had to be enforced collectively, when the rich and powerful attempted to take possession of land, fence it off, exploit it commercially, etc. Lammas Day was thus also a day when battles around enclosure often took place, as the ritual significance of the day was a central part of the rural year, and the ritual opening up of land for grazing was a useful arena for protest around loss of access. August 1st often became a focus for action when common rights/customs were threatened; an annual ritual #OnThisDay in London radical history, 1592: enclosure fences destroyed, Westminster https://wp.me/p74yfw-Hp Another Lammas Day anti enclosure action: Leyton Marsh 1892 Resisting enclosure past & present: East London Waterworks, Leyton Marsh, and the Leyton Lammas lands https://wp.me/p74yfw-XN

24.7.2014: Viilarintie. Herttoniemen satamaradan metron yhdysraiteena toiminut osuus on juuri purettu, mutta pikaraitiotien rakentaminen alkaa vasta viiden vuoden päästä. Merkki ennakoikoon sitä. Tulevina vuosina paikka muuttuu niin, ettei sitä enää tunnista samaksi. Karhukalliontien risteys tulee tähän ja ympärille korkeita kerrostaloja. Jostakin syystä (sievistelyäkö?) alueen nimi muuttui Karhunkaatajasta Karhukallioksi. #onthisday #ItäHelsinki #Myllypuro

John Tukey the Fast Fourier Transform (FFT) inventor, who coined both "bit" and "software" died exactly 26 years ago today. The Fast Fourier Transform (FFT), one of the most important algorithms in signal processing and data analysis, was introduced by Tukey & Cooley in 1965. In 1805, Gauss - studying the orbits of asteroids Pallas and Juno - came up with a method to interpolate their trajectories from discrete samples. What he came up with was mathematically very close to the modern FFT but Gauss never published that work, and didn’t analyze its computational complexity. It predated even Fourier’s 1822 work on heat diffusion - but without the framing or generalization that Cooley & Tukey would bring 160 years later. In 1965, Cooley & Tukey published their now-famous algorithm that reduced the cost of computing a Discrete Fourier Transform from 𝑂(𝑛²) to 𝑂(𝑛 log⁡𝑛). This leap made real-time signal processing and digital media compression feasible. From radio telescopes to JPEGs, from audio codecs to quantum mechanics - the FFT is everywhere. It’s one of the most important (and elegant) algorithms of the 20th century - rooted in the genius of Gauss, but brought to life in the computer age. #JohnTukey #FastFourierTransform #FFT #SignalProcessing #ComputerScience #Mathematics #Algorithm #DataScience #DigitalSignalProcessing #FourierTransform #ComputationalScience #ScientificComputing #HistoryOfScience #Innovation #CarlFriedrichGauss #JosephFourier #JamesCooley #STEM #Engineering #ArtificialIntelligence #MachineLearning #QuantumComputing #ImageProcessing #AudioProcessing #Statistics #TechHistory #Computing #Science #InnovationLegacy #OnThisDay
