How about going there completely disguised, and pretending to go to a different floor in the building than Fahim? If he went there to talk to him, he wouldn't press a button in the elevator for a different apartment.
> If you have the correct antennas and possibly amplifiers on both ends you can established a Wifi link over hundreds of miles (if you have line of sight). Basically, if you can see the other device you want to communicate with at building level with your eyes then it's not too difficult to establish a Wifi link with it using off the shelf parts.
I can't speak to hundreds of miles, but I built a Wifi bridge that went about 1.75 miles across a cow pasture with center-pivot sprinklers using a pair of WRT-54G routers, DD-WRT, and some yagi/panel antennas from Amazon about 10 years ago. Total price was under $300 and speeds of 11mb were all we went for as it was just feeding a PC for browsing and time-card punches in a shop across the pasture from the office.
It ran happily for nearly 6 years before being replaced with a packaged kit of antennas and POE injectors that advertised 54mb over 2-3 miles seamlessly for around the same price.
If you had a pile of old 802.11b gear and the time and gumption, I'd think you could build something like this for sub-$50 at this point.
It seems like they’re maybe Apple-exclusive so it’s possibly they’re drastically marked up. The Titan RTX is $2500 apiece and seems somewhat comparable.
I think your issue may be with the exponential scaling of GPU cost at the highest end. As a consumer, you wish that a card ~2x the Titan in tflops only cost twice as much, but it doesn’t work that way for either platform, and of course isn’t helped by the workstation card market being smaller by unit than the retail/ORM gaming card market.
That said I did not downvote you; it’s an understandable frustration.
