Switched hotels to get away from the plastic shower. Success!

@noplasticshower It's important to have standards!

With the administration now recommending memory safe languages, I'm assuming the RNC platform is going to talk about preserving our god-given freedom as Americans to overwrite the stack whenever and wherever we want.

@stevegrunwell that was literally the PL/C model - the compiler never aborts, no matter how nonviable the code.

Captured with the Rodenstock 50mm/4.0 HR Digaron-W lens (@ f/4.5) on a Cambo WRS-1600 camera (with about 15mm of vertical shift to preserve the geometry), the Phase One IQ4-150 back (@ ISO 50) in dual exposure mode (which preserves a couple stops of additional dynamic range into the shadows).

The tower's shape is irregular; it tapers slightly.

The wide angle and landscape orientation give it context, alone on a hill (which is being rapidly encroached by adjacent residential development).

For much of the 20th century, the backbone of the AT&T "Long Lines" long distance telephone network consisted primarily of terrestrial microwave links (rather than copper or fiber cables). Towers with distinctive KS-15676 "horn" antennas could be seen on hilltops and atop switching center buildings across the US; they were simply part of the American landscape.

Most of the relay towers were simple steel structures. This brutalist concrete platform in San Jose was, I believe, a unique design.

By the 1980's, the terrestrial microwave network was overtaken by changing engineering and network economics. Microwave links, while relatively inexpensive to provision, simply could not compete with fiber optic cables for the growing bandwidth requirements of modern telecommunications. By the turn of the century, most of the towers were sold off and re-purposed for cellular or land mobile radio.

Often the classic horn antennas were abandoned in place, too big and heavy to remove safely.

The San Jose Oak Hill Tower is unique in a number of ways. The concrete brutalist design appears not to have been used anywhere else; it seems to have been site-specific. It sits atop an underground switching center (that was partly used for a military contract), which explains the relatively hardened design.

Today the underground switch is still there, owned by AT&T, but the tower space is leased to land mobile and cellular providers. The horn antennas are disconnected relics.

@Da_Gut There are not. The network was completely decommissioned.

mattblaze,

@Da_Gut There are microwave links here and there, but they weren't part of the old Long Lines network. All the horn antennas still in place are ruins.

With a few exceptions (towers built-in to switching offices in densely populated areas), no one was trying to make any of this communications infrastructure beautiful. It was form strictly following function, built to be reliable and rugged.

But there was, I think, quite a bit of beauty to find in it. I wonder if we'll look at our current neighborhood cellular towers, typically regarded as a visual blight, that way decades after they're gone.

@karlauerbach Those fake-tree towers always remind me of the poor dog with antlers strapped to his head in How the Grinch Stole Christmas.

@ClemFandango @Da_Gut Sounds like someone got creative and repurposed one something old.

@mhjohnson Oh, that's nice.

I have mixed feelings about Le Corbusier's architecture (to say nothing of his urban planning philosophy), but I think the UN Secretariat building was quite successful.

mattblaze,
@mattblaze@federate.social avatar

@midendian It was. The fences have always surrounded the complex, though the access policy has changed over time (e.g., the steps to the visitor center to the north used to be open all the time).

If you look at the full resolution version, you can see the HF amateur radio antenna on the roof. Nerds are everywhere, even at the UN.

@skydog oh please

mattblaze,
@mattblaze@federate.social avatar

@skydog Dude, the UN does not need a secret HF listening post in the middle of NYC.

@karlauerbach I don’t think I know that building!

@stshank All in camera! And yes, definitely recommend renting.

@karlauerbach Yes, historic homes are great as long as you aren't the owner!

@offby1 The perpendicular street across the avenue is on a hill, and dead ends with a staircase.
