Why New York Subway Lines Are Missing Countdown Clocks

  • There is a whole world down there: a warren of rooms and equipment, including a working section of track about 20 yards long, that comprise the subway system’s Signal School.
  • The switches are connected by wire or still, in some cases, by actual levers, to rooms called “towers” where operators can see which sections of track are occupied, what color the signals are, and what the state of each switch is.
  • This complex—of towers, signals, switches, and track sections—is responsible for a disproportionate share of the costs and foibles in the operation and maintenance of New York’s subway system.
  • The MTA, too, thinks it’s ridiculous that all a tower operator knows when they look at their board is that some hunk of steel—which one, they can’t be sure—is sitting on some section of track.

Story of XL1

  • In late 1982 Pete had ordered a Sinclair Spectrum by mail order, and one of the first BASIC programs he wrote put up the lyrics to one of his songs prompted by key presses.
  • Pete was at the time writing songs for his new solo album following the success of Homosapien, and he thought it was a great idea to include a Spectrum program with the album containing all the lyrics.
  • With three weeks until the album was to be finished, I moved down to the hotel to work on the program full time.
  • With only a few days before the album had to be finished, Pete still had two songs to complete, one of which only had a title.
  • This coincided with Elvis Costello finishing his album, so he played us his album in the studios control room, and then we played him ours with the added bonus of the Spectrum program.

StarVR puts developer program ‘on hold’ as financial woes roil Starbreeze

  • Last month, StarVR stated that its first production units for StarVR One were ready.
  • Developers could apply to purchase the headset, which featured 210-degree horizontal-by-130-degree vertical field of view, dual AMOLED panels, integrated eye-tracking and SteamVR 2.0 tracking (though no SteamVR base stations to actually track the device).
  • Ahead of the launch, StarVR announced that it was delisting StarVR from the Taipei Exchange Emerging Markets board, citing the current state of the VR industry as one reason.
  • Then, earlier this week, we learned that headset creator Starbreeze, which now owns around a third of StarVR (the other two-thirds belonging to Acer), had filed for reconstruction with the Stockholm District Court.
  • It’s uncertain what this means for the future of the VR headset, which had been designed for location-based and enterprise experiences.

Apple releases new Beddit sleep tracker

  • Apple has released the first Beddit sleep tracker since acquiring the Finnish company in 2017, via CNET.
  • The Beddit 3.5 Sleep Monitor is a thin sensor strip that can be placed under the bedsheet to track body movements through the night.
  • The advantage over other sleep monitoring fitness trackers is you don’t need to wear an activity tracker to bed, or remember to use it.
  • You can still connect it to your Apple Watch, which can display sleep report notifications, bedtime reminders, and nudges when synced.
  • Your sleep analysis and heart rate data is also accessible through the Health app on iOS 12 or later.
  • The Apple Watch Series 4 still doesn’t offer any native sleep-tracking abilities, but for now there’s third-party apps that’ll help track your bedtime, including Beddit’s own app.
  • Until then, Apple’s new Beddit Sleep Monitor is looking to fill that gap.

Simulated One Gravity Living on the Moon and Mars With a Supertrain

  • The moon has one-sixth the Earth’s gravity and Mars gravity is 38%.
  • There will be negative health impacts for people to live for extended periods at lower gravity.
  • Dr. Joseph Parker presents a gravity solution for living on the moon or Mars.
  • We need to have people live in one gravity pods on a circular hyperloop like track.
  • The actual moon or Mars tracks would have pods or trains going a bit slower and on an angle to get the right gravity.
  • It is a 70-degree angle on Mars.
  • People and their children would live on these large trains.
  • People will go onto the docking train to go to work in the lower gravity and then return to one G living and sleeping.
  • This train solution aligns with Elon Musk’s development of the Boring company and Hyperloop.

New York City's secret subway line with antique cars is back in service — here's what it's like to ride it

  • The train line, consisting of eight vintage New York subway cars from several different eras, runs for a few weekends each year — from the Sunday after Thanksgiving to the end of the year, only on Sundays.
  • Subways in New York don't usually stand in a station for longer than a minute or two, but this one stops to pose for photos for at least a few minutes.
  • The Holiday Nostalgia train line runs every Sunday from 10 a.m. to 4 p.m., starting on November 25 and ending on December 30.
  • Rides cost the same $2.75 that all subway rides cost, and you can take the train as many times as you'd like.
  • And if you miss it, don't worry too much — the entire subway line is normally on display at the New York Transit Museum.

Alexa can now find the right Amazon Music playlist by having a conversation with you

  • Amazon Music is gaining a few new Alexa-powered voice features today.
  • Coming soon, customers will also be able to ask, “Alexa, recommend some new music” to further help with discovery or simply, “Alexa, what should I play?” By using cues from your previous listening habits, and asking a few simple questions regarding your favorite genres, eras and other preferences, Alexa will be able to anticipate what customers are in the mood to hear, and suggest relevant music, or new releases tailored to them.
  • Customers listening through either Prime Music or Amazon Music Unlimited can ask Alexa for playlist advice starting today.
  • In general, Alexa is getting smarter about playing what you actually like on Amazon Music when you simply say “play music.” The songs you hear should be better tuned to your tastes.

WALL·E – Typeset in the Future

  • The bold extended typeface seen on WALL·E’s front plate is Gunship, designed by Dan Zadorozny, one of the unsung heroes of modern sci-fi type design.
  • Unlike the top-of-rail system seen in WALL·E, Cheshunt’s monorail consisted of carriages suspended beneath an overhead track, and was powered by a single horse.
  • It’s not entirely clear what US city WALL·E lives in, but the presence of a monorail network certainly positions it as a location that was once optimistic about the future.
  • Near the monorail, WALL·E passes a promotional poster for himself, with the caption “Working to dig you out!” This poster has definite communist propaganda undertones, showing a stylized army of WALL·Es working together to build a brighter future.
  • I say “almost,” because the real-world iPod Video had a smaller click wheel than the one seen in WALL·E, had white labels on its buttons, and did not support external playback from a VHS cassette player.

A Visual Defragmenter for the Commodore 64

  • Every directory entry consists of a file type, a 16 byte file name, and a track/sector tuple for the first block of the file.
  • The following code iterates over all directory entries and follows the linked lists of all files, recording in the array ci() the logical block index for each physical block.
  • Since we are using linear block indexes for everything, we need to convert the track/sector tuples that the filesystem works with.
  • When updating links during defragmentation, we will need to convert linear block indexes back into track/sector tuples, so we create the two arrays tr() and sc() for a quick lookup.
  • In order to move a block, in addition to copying the data between the two physical blocks and updating our data structures, we also have to update the track/sector link tuple from the previous block or the directory entry.
