There was a homoerotic element in the fishnet stuff I always thought. And HR would have a fit if you asked women to wear that stuff now, err, I mean in 1999.
I did the same: tended to use Apple services then when I hit poverty I was able to use my NAS copies of music and videos after cancelling subscriptions. Had a "so why was I paying for years?" moment especially with all the enshitification issues
"illegal fluid" what would that be? And why illegal? And do you submit the recovered data anywhere, for data archaeological purposes? Seems an important thing.
That was a bit tongue-in-cheek.. and a more accurate word would be "banned", not "illegal". It's just something HP used to sell, not dangerous as such, but it's a CFC-based tape head cleaner. Very efficient, and leaves nothing behind. But they stopped selling that particular variant after the Montreal protocol was in place, but I kept a bottle around.
And formerly available at any pharmacy. When I cleaned out my parents house I found a bottle of it in the laundry room. I guess my mom used to use it on stains.
"Boil it down and this means the quantum clock loses only one second every 30 billion years, which, for navigation purposes, means a drift of a mere 1 x 10⁻⁶ degrees per hour. "
What does this mean in terms of metres off a desired position?
That's not how these inertial navigation units work. They measure the acceleration of the device in six axes. Forward/back, up/down, left/right, yaw, pitch, and roll. Then they integrate these accelerations to determine current velocity. Then they integrate velocity to determine position. Really the above calculation is a bit of a spitball, because it will vary depending on the motion of the submarine.
In the inertial reference frame of Earth, the only celestial body you really need to worry about are tidal forces from the moon. Every other body is too far away for tidal forces to be a problem. They average out across the entire inertial reference frame.
Typically such systems need to be aligned every so often. This means you set the "Initial Conditions" of your integration. Typically position can be aligned easily using reference points to re-align your INS. The SR-71 did this using celestial points. Submarines can use sonar beacons and low frequency radio to passively align position. Planes and GPS/INS guided munitions now mostly use GPS to maintain alignment.
Old school ring laser gyros were unfortunately only good for about a couple hours before realign was necessary. Which is perfect for a fighter jet, missile, or bomb which will only fly that long occasionally. This new system can align every couple weeks or even months. Especially if the sub is stationary for long periods of time.
This is true. It’s not meant to be run with any prompt but the one they trained with. I found that out as well. It’s only meant for ocr. Qwen 2.5vl is better if you need that option.
I abandoned ocaml just because I couldn't get a stepping debugger to work. Can't remember the exact issues but I tried to install in vscode to no avail & I've no interest in emacs
