  • Oh, speaking of scifi, I read another article (which I cant find now, unfortunately) about space walks: astronauts can’t just climb into a space suit and exit the space station, because that would cause decompression sickness. They have to undergo about 24 hours of preparation, then spend time in a decompression chamber once they re-enter the station. I can’t find the article I read atm, but here’s one from space.com that talks about it:

    About 24 hours before the spacewalk, astronauts undergo decompression, the same procedure divers follow when returning from the depths of the ocean to the surface of the water. Inside the space station, air is pressurized to the same degree as it is on Earth at sea level: 14.7 pounds per square inch, or 1 atmosphere.

    But inside a spacesuit it’s 4.3 psi, according to NASA, which is about the same pressure experienced at 30,000 feet (9,000 meters) above Earth. Experiencing a rapid drop in pressure from 14.7 to 4.3 psi causes nitrogen bubbles to form in the bloodstream and get stuck, blocking blood flow — a condition known as “the bends” or decompression sickness. To avoid the condition, astronauts camp out the night before in a closet-sized airlock while wearing their space suit so their bodies have time to adjust to the change in pressure.

    e: Sandra Bullock would have died of decompression sickness pretty quickly.

    Uh, what? Have you owned a Mac in the last 30 years?

    That’s not how it works. I’ve had two macs in the last 20 years, and more than a dozen Windows machines. I had to reformat the Windows PCs every year or so for various reasons until they became obsolete after like 5 years, but my macs have worked for 10 years each with no issues, and always upgraded to the latest OS easily and always for free. Both my macs lasted 10+ years of heavy use (my current one is 5+ years and still young).

    Every time a Windows update came out it was an ordeal and I dreaded it; with each update I’d start looking at the cost of replacing the whole machine in case it bricks and it’s just not worth fixing things. Mac updates are barely a blip in my workflow.

    Adobe projects that can’t be accessed on a workstation not running Monterrey or whatever

    This makes zero sense. The Adobe suite runs much better on OSX than Windows by orders of magnitude, even on outdated and non-updated OS. There’s a reason most designers and professional VXers have always preferred Mac. (eta: also, rereading, this makes even less sense because Adobe projects don’t care about your OS when opening; just the version of Adobe itself. You can easily open projects made on a whole different OS: Windows/OSX, any recentish version with no problem. Even files made in CS6/OSX can be opened in the latest cloud app on Windows easily. You’re either mistaken here or being deliberately dishonest for some reason.)

    I’ve been in IT/software development and VX design for a few decades and I’m really wondering how this is an ordeal for you. It makes no sense to me. My 3000 dollar laptop has outlasted 5 1000 dollar windows machines. You get what you pay for.

    e: some words were cut

    Also, in my few decades in the industry, the sales and marketing staff always ran Windows, but the design staff usually worked on Mac. That speaks for itself.
