@Tesla Stuck in limbo in Lithuania. 🇱🇹 FSD is officially approved, but we haven't seen an update in nearly 2 months. Still trapped on 2026.8.6 with no FSD functionality on HW4. Why the delay, @Tesla? We’re ready to go! #TeslaFSD #Lithuania @Teslaeurope @elonmusk

In 2020, ancient Roman mosaic floor discovered under vines in northern Italy 🇮🇹 In an extraordinary archaeological discovery, stunning Roman mosaics have been unearthed beneath a vineyard in picturesque province of Verona, near the town of Negrar di Valpolicella, Italy. This find offers a fascinating glimpse into the opulent lifestyle and artistic achievements of the late Roman Empire, dating back to 3rd-4th Centuries AD. Negrar di Valpolicella, a charming town in Verona's province, renowned for its historical richness and agricultural traditions, particularly its vineyards. The discovery of the mosaics in this region emphasizes the seamless blend of Italy's historical and contemporary cultural landscapes. This area has long been recognized for its significant archaeological potential, and this recent find confirms its status as a treasure trove of Roman heritage. After the discovery in 1922, the site was mostly left abandoned until a team from Superintendent of Archaeology, Fine Arts and Landscape of Verona resumed digging last summer. The team returned to the site in October 2019, and again in February 2020, before excavation was suspended because of the coronavirus pandemic. The mosaic was found a few metres beneath a row of vines a week after work got going again. The mosaics date back to a period when Roman Empire was at the zenith of its cultural and artistic development. The 3rd-4th Centuries AD marked a time of great sophistication in Roman art, architecture, and lifestyle. During this era, Roman villas were often adorned with intricate mosaics that showcased the wealth and status of their owners. The mosaics in Negrar di Valpolicella are exemplary of this trend, reflecting the high level of craftsmanship and artistic expression characteristic of the late Roman Empire. The discovery was part of a concerted archaeological effort to locate the remains of an ancient Roman villa first identified over a century ago. Underneath a vineyard, the archaeologists unearthed these remarkably well-preserved mosaics, revealing intricate designs and vibrant colors that have survived for nearly two millennia. The mosaics likely adorned the floors of a luxurious Roman villa, providing insights into the daily life and aesthetic preferences of its inhabitants. Surveyors in commune of Negrar di Valpolicella north of Verona published images of well-preserved tiles buried under metres of earth. According to officials, scholars first found evidence of a Roman villa there more than a century ago. Team discovered tiles, as well as portions of villa’s foundation, “a few meters” below the vineyard’s surface. Villa cover an area of 300 square metres. Technicians are still gently excavating the site to see full extent of ancient building. “After countless decades of failed attempts, part of the floor and foundations of the Roman villa located north of Verona, discovered by scholars a century ago, has finally been brought to light,” authorities from Negrar di Valpolicella. “The superintendent will now liaise with the owners of the area and municipality to identify the most appropriate ways of making this archaeological treasure, which has always been hidden beneath our feet, available and accessible.” Roberto Grison, the mayor of Negrar di Valpolicella, told the local newspaper L’Arena: “We believe a cultural site of this value deserves attention and should be enhanced. For this reason, together with the superintendent and those in charge of agricultural funds, we will find a way to make this treasure enjoyable.” #archaeohistories

Every one of these dots is an actual crash from the fleet. Real world speeds, collisions, and people. Not just the regulatory test cases. The richness of this data is what enabled the result. With simulation we can replay the crashes and measure the forces on the human body

"Brushless DC motors are already so optimized that you’re not going to get much more out of even the best designs.” .. Jerry Pratt.

AC vs DC motors

Electric Traction Electric Traction means using the electric power for traction system i.e. for railways, trams, trolleys etc. i.e. use of the electricity for all these. Now a days, magnetic traction is also used for bullet trains. Basically DC motors are used for it.

This is probably the true meaning of using your brain 🧠

@mattyboobaddee @maddenifico The ONLY plan the government has when ✡️ AI, self driving cars and robotics (funded by $500 BILLION tax dollars) take our jobs away is: they passed anti-riots law, treating protesters as terrorists and militarizing the police!

Will be amazing with self-driving cars capture videos or extremely reckless drivers and sends those videos to law enforcement in real time In the future ten Waymos, Teslas and Ubers will track the same insane driver across the 405!
