  1. Since I haven’t looked at the phase 2 plans for a while, a recap and update was due. None of this will be news to those who already follow the development closely. The tail tracks will cross the Lenox Avenue branch. (Sauces: https://www.transit.dot.gov/sites/fta.dot.gov/files/2022-01/NY-New-York-Second-Avenue-Subway-Phase-2-Eng-Profile.pdf; https://www.cb11m.org/wp-content/uploads/2018/03/CB11-4.14.21-SAS-2-Update-final2.pdf) Placing platforms where 116 Street’s middle track would have been appears to be the current plan still. 125 Street still had a middle track in old plans. A repeat of what happened to 72 Street is set in stone. (Sauce: https://new.mta.info/document/22416)
  2. For a much lower cost and increased flexibility, would it not be much cheaper to just install switches north of 57 Street–7 Avenue? A lot less excavation (if any) and the SAS-Broadway connection is no longer locked to a particular pair of tracks.
  3. Off-topic, but assuming this is the case and reamains the case once SAS gets far enough along, perhaps the ’s trains could be based out of Coney Island Yard. For morning rush, s end at 125 Street and continue in service as s. For evening rush, s head back to Coney Island as s.
  4. Acknowledging them would also backfire. The recordings would make them infamous; then girls start throwing their panties at them/the train.
  5. * for most of life Not reacting favorably to being surprise-touched from behind has been the product of a half billion years of evolution.
  6. The root cause is not the file system either. You could technically put any file system you want on the card (e.g., ext2). The limit comes from the card-specific data (CSD) structure, which an SD card (using the original standard) uses to report its capacity. There are actually enough bits in the structure to support up to 4 GB, but whether it’s accessible relies on the hardware (i.e., the card reader) supporting it. The OS/FS doesn’t mean a damn thing unless the card’s bytes can be addressed. You would be correct if this were about SDHC versus SDXC. The key difference between the two is the file system—FAT32 versus exFAT, the latter which enables capacities higher than 32 GB. (But it should be noted that FAT32 can technically go up to 16 TB with larger cluster sizes.) I disagree with that. Ancient history is very important in the industries which typically rely on ancient technology. I can’t comment on which technologies the MTA’s equipment runs on, but it sure isn’t cutting edge. This whole exercise was to make the points that: Legacy technology and backwards compatibility holds back innovation. Just because something could be done in the consumer space doesn’t make it an appropriate solution for industrial/enterprise use.
  7. You’re missing the forest for the trees here. The original SecureDigital card limitations weren’t OS-level limitations. They were baked into the standard which had to be revised to allow for a bump in maximum capacity. Perhaps the 2 GB limit and 32-bit addressing coincide, but if that were the case, how do you explain the 32 GB limitation of SDHC? Or the 2 TB limitation of SDXC? Or the 128 TB limitation of SDUC? Are SDHC cards using 35-bit microcontrollers?
  8. Not having an officially sanctioned bathroom break doesn’t stop all train crew members from taking one anyway. I was on a train where the T/O stopped in the middle of the tunnel to take a piss out the storm door. The sigh of relief was audible through the cab door. C/O covered for him by making the usual announcement when trains stop in between stations: we have a red signal ahead of us. lol
  9. But this is exactly what I wrote in the beginning: you’re simply shifting them elsewhere. People don’t spend all their time on the subway. Once they get out, that’s where all the homeless people will be—the same ones that the MTA cleared out. You don’t solve the problem by deferring it.
  10. I’m intimately familiar with the limitations as I have been using SecureDigital cards since the initial 128 MB capacity. The 4 GB SDHC cards required a new card reader because the larger capacity was not backwards compatible with older readers. Same with SDXC when that came out. And so far, no SecureDigital card on the market exceeds 1.5 TB (of which Micron is the sole manufacturer). When I say the “original SD standard,” I mean to the exclusion of SDHC (SecureDigital High Capacity), SDXC (SecureDigital Extended Capacity), and SDUC (SecureDigital Ultra Capacity). The limits of each type are listed below (c.f., https://www.sdcard.org/consumers/about-sd-memory-card-choices/sd-sdhc-sdxc-and-sduc-card-capacity-choices/): SD: 2 GB SDHC: 32 GB SDXC: 2 TB SDUC: 128 TB This is without the additional complication introduced by physical card sizes, supported protocols, bus speeds, minimum bandwidth, or minimum IOps.
  11. Believable. I used to cut classes too just because I felt like it. 😏
  12. And they had to pick a Thursday in the middle of the day? Who’s going to fan those? Retirees? lol
  13. I mean… that’s still consistent with what I said. The solution (software, hardware, configuration) remains the same, but the data that it processes (i.e., the audio files) changes. All it takes is one weak link in the chain requiring backwards compatibility to spoil the potential tech advancement options for the rest. For example, the original SD standard capped memory cards to 2 GB. If some hardware were developed around a platform that hadn’t updated its controllers, then every future product developed around that platform would be held back on SD card capacity.
  14. You would be amazed how slow tech moves in some industries. There are also many considerations besides “it can be done.” For example: what has been working and shouldn’t be touched? That’s why you find ancient programming languages like COBOL being used in financial systems or nuclear weapons systems still reliant on floppy disks. The same is true for consumer markets. ECC RAM exists to prevent memory corruption from irreversibly ruining digital archives (e.g., your family videos, tax returns PDFs, etc.). Market segmentation prevented most consumers from benefiting from it even though it’s been used for decades in the enterprise and industrial segments. Perhaps the MTA leans a little too conservatively and needs to make a clean break with its past.
  15. The question is: where are these people ultimately coming from and in what proportions? Assuming the switch is made: People (the NYP staff) east of Forest Hills would be the biggest losers. People along the local stops from Forest Hills to 36 Street would be the biggest winners. People getting on at Forest Hills or Jackson Heights (including those from Woodside, Elmhurst, Corona, and Flushing) would be somewhere in between. Also to be taken into consideration: The NYC Health + Hospitals / Metropolitan at 96 Street () Northwell Health at Lexington Avenue/53 Street () NYU Langone Health at 33 Street and 1 Avenue () NYC Health and Hospitals / Bellevue at 28 Street and 1 Avenue ()
  16. The whole of 2 Avenue is basically lined with hospitals. Two of my friends worked for NYU Langone, which is located at around 34 Street and 1 Avenue. They’d walk to/from Lexington Avenue to avoid taking the bus. So I guess in either service setup, one group will win and the other will lose. Ten years ago, I told the two of them that SAS was coming to save them. I chuckle at my naïveté today.
  17. Might makes right. Squeakiest wheel gets the grease. Yada yada…
  18. lol Imagine people get a taste of via 53 Street and then community pressure demands that the MTA make it permanent with the on 63 Street.
  19. I can’t imagine any normal (or reasonable fantasy) scenario where backtracking to Roosevelt Avenue is a better option than taking the local in the right direction and just transferring in Manhattan.
  20. 128 GB industrial SLC MicroSD cards don’t exist. In fact, 64 GB only just came out. And a few years back, the highest capacity was a mere 16 GB. Now, it’s only speculation that the MTA uses MicroSD cards for its embedded storage, but the same performance/capacity characteristics apply to pretty much any memory you’d use in critical equipment. I would keep this in mind: Also keep in mind that just because something new came out now doesn’t mean they can just switch to it. New components require costly validation cycles to make sure everything works together. The trains rolling onto the tracks now are probably trains designed when even 16 GB cards weren’t on the market. If you’ve ever checked out the market for Wi-Fi routers, you’d notice that every couple years, a faster Wi-Fi standard gets announced, and somehow the likes of Netgear has a product supporting it before the standard’s even finalized. Often, these products end up not working the way the standard intended and have problems down the line. That kind of bleeding edge is for people like you and I who can just go out to Best Buy and switch out a shoddily designed router when the internet goes down. You can live for a couple hours without Netflix or League of Legends. Not so for hospitals, banks, vehicles, etc.
  21. 1 TB of what? Among the memory products out there, the industrial memory products are always lower capacity and slower. Take the MicroSD card for example. This form of memory powers many embedded computing platforms like the Raspberry Pi. Normal MicroSD cards like the kind you would use in a phone or camera are designed to be fast and expendable high-capacity storage chips. The industrial kind are slow, low-capacity, but reliable. Remember that the trains have to go through rain and sunshine, hellfire and hell freezing over, while meeting reliability levels greater than can be provided by consumer-grade electronics.
  22. The Steinway Tube is laughing at your right now.
  23. The fact that any track connection is planned is more than any fantasy R.O.W. that’s been discussed.
