  1. Completed signal box with signalman, lever frame, furniture, and overhead light. Most of what’s in there is barely visible, but a lit empty room with big windows like these stands out a mile.

    The full complement of ten buildings are now ready for the branch line boards. Next up, semaphore signal electronics and 3D printed mounts, and then to build the station platform up from the 3D prints I’ve got ready.

  2. Robert Melancton #Metcalfe feiert heute seinen 80. Geburtstag. Er gilt als der Erfinder des #Ethernet. Alles Gute zum Geburtstag.

    1997 musste er seine Prognose, dass das Internet kollabieren würde, im wörtlichen Sinne aufessen. Das hat ihm offensichtlich nicht allzu sehr geschadet. 😜

  3. Station construction is all complete but for a couple of small details. I do then need to add posters, platform furniture, and people - as a minimum - and finish programming the signals. Then I can think about ballast!

  4. Hype for the Future 134A: City of Edmonton, Kentucky

    Overview The City of Edmonton is located within the central portion of the Commonwealth of Kentucky in Metcalfe County, serving as the county seat and bypassed by the Louie B. Nunn Cumberland Expressway. Travel to the community is largely via United States Route 68 and Kentucky Routes 80, 163, 496, and 533. The surrounding area is also accessible via Routes 1243 to the northwest, 543 to the north, 544 to the northeast, 869 toward the Sulphur Well Historic District, 745 southeast of 68 to the […]

  7. Time to get the fiddly canopies into the station buildings. And they are fiddly. Lot of measuring.

  8. This lunchtime I’ve spent some time working on incorporating hanging lights into the Metcalfe platform canopies. It’s going quite well so far. Taken my time to work out exactly how to get the lamps where I want.

  9. Platform 1 and the associated buildings contribute to make slow but steady progress…

  10. Today the LED lights for lighting up the inside of the buildings on my model railway were delivered, meaning I can finally start building some of them! First up is the main station - a ticket office and a parcel depot (Metcalfe kits) on a 1500mm long platform.

    Pics to follow.

  17. "Despite his role in its foundations, Dr Metcalfe later doubted the hardiness of the internet as it became a global phenomenon. He predicted that the whole shebang would “go spectacularly supernova and, in 1996, catastrophically collapse”. The collapse never happened, and Dr Metcalfe literally ate his words. At a conference in California, he produced a print-out of his prediction, pureed it in a blender and slurped it up with a spoon." 😬

  19. #ACM named #Robert #Metcalfe recipient of the 2022 ACM A.M. #Turing #Award for leading the invention, standardization, and commercialization of #Ethernet local-area networking technology.

    Metcalfe is Emeritus Professor of Electrical and Computer Engineering (ECE) at The University of Texas at Austin.

    In 1973, while a Research Scientist at the Xerox Palo Alto Research Center ( #PARC ), Metcalfe circulated a now-famous memo on May 22, 1973 describing a "broadcast communication network" for connecting some of the first personal computers, #Altos, within a single building.

    The first Ethernet ran at 2.94 megabit per second, which was ~10,000 times faster than the terminal networks it replaced starting in 1973.

    Although the original design proposed implementing this network over #coaxial #cable, the memo envisioned "communication over an #ether" making the design adaptable to any future innovation in media technology including legacy telephone twisted pair, optical fiber, radio, and even power networks, to replace the coaxial cable as the "ether". That memo laid the groundwork for what we now know today as Ethernet.

    The Ethernet architecture was developed to address Xerox's need to connect 100 of the new Alto personal computers and their new laser printers. The original architecture was based on a single wire bus with a single transceiver per node, thus enabling a cost-effective design.

    The media access control in the Ethernet design incorporated Metcalfe's insights from his experience with Norm Abramson's RIP #ALOHAnet.

    Metcalfe recruited David Boggs RIP to help build a 100-node Ethernet in two years. That first Ethernet was then replicated within Xerox to proliferate a corporate internet.

    Metcalfe and Boggs' classic 1976 CACM article, "Ethernet: Distributed Packet Switching for Local Computer Networks," described the design of Ethernet. Metcalfe then led a team that developed the 10Mbps Ethernet, deployed internally at Xerox and forming the basis of subsequent standards.

  20. Why small teams win. #Metcalfe's law says that every time you add a new user to a network, the number of connections increases proportionally to the square of the number of users...
