For me 1.0 only means that I’ve delivered the software to a paying customer.

Which theory explains why he has not accomplished the above.

If that’s a Tomcat, where’s that lizard’s RIO?

Windows does, in fact, have signals. They’re just not all the same as Unix signals, and the behavior is different. Here’s a write-up.

You’re correct there is no “please terminate but you don’t have to” signal in Windows. Windowless processes sometimes make up their own nonstandard events to implement the functionality. As you mentioned, windowed processes have WM_CLOSE.

Memory access violations (akin to SIGSEGV), and other system exceptions can be handled through Structured Exception Handling.

millia pasuum, literally “1,000 paces,” was a common unit of measure in the empire, and the basis of various modern miles. It was slightly shorter than the modern statute mile.

It was also common to have a single step mode, where the CPU advances one cycle per switch press. Very useful for debugging.

And you could frequently read out the contents of registers directly on rows of lights. This led to the trope of the blinky light computer in Star Trek (original series) and elsewhere. Because the lights would flash in various patterns when the computer was running, as the register contents changed. But in the single step mode you could interpret the values.

Nvidia has entered the chat.

But, but, the other terminal on those batteries is floating?

I’m pretty sure on newer 737s the autopilot disconnects when it detects a sufficient physical force on the yoke.

On airplanes that don’t do this, the autopilot servos are clutched so that you can still override them by applying a specified amount of force. There are reinforced points on the bottom of the dash panel that you can use with your foot to get leverage to help with this.

(This also applies as a backup on planes that do disconnect)

Some more practical tips.

• if the autopilot is engaged, you can’t physically move the wheels, because it is moving them for you. Press the red button on the steering wheel to disconnect autopilot.
• That IAS tape on the left of the sky/ground box is the most important thing on the plane. It’s got red bands on the high side and low side that you should stay out of.
• if the plane tells you there’s a “stall, stall” you need to push the wheels forward to make the nose go down. And keep the speed above that lower red band.
• the black button on the wheel is the push-to-talk to talk on the radio, or maybe the internal PA system. Depends how it’s set up.
• most important: the switch for the “fasten seatbelt” sign is usually on the bottom of the top panel. You can flip it on and off as much as you want. (Older planes will also let you do this with the “no smoking” sign).

And Hawking radiation. Hawking radiation is pretty “dark” for solar-mass scale black holes and up, but it can become relatively very intense for smaller holes.

For the holes we observe astronomically, the things we can see are the accretion disks and the orbits of stars around the black hole.

You missed “CM,” which was common in copyright statements in the 20th century.

It’s pretty well settled mathematics that infinities are “the same size” if you can draw any kind of 1-to-1 mapping function between the two sets. If it’s 1-to-1, then every member of set A is paired off with a member of B, and there are no elements left over on either side.

In the example with even integers y versus all integers x, you can define the relation x <–> y = 2*x. So the two sets “have the same size”.

But the real numbers are provably larger than any of the integer sets. Meaning every possible mapping function leaves some reals leftover.

If you’re getting into private jets, you should also know that brands have reputations even there.

Gulfstream is a luxury brand within the private jet world. You can easily get a comparable product from Bombardier or Cessna Textron that performs equivalently, but only pay half as much operating costs as Gulfstream. Like Gucci, you pay a lot of money just for the Gulfstream name.

At the low end of the market, Honda makes a small jet. (This is in the Very Light Jet category which bumps up against the turboprop market).

At the very high end of the market you get into Boeing Business Jets, and the Airbus equivalent. These are converting airliners to your exact interior design specifications. Airliners are like another order of magnitude higher cost to operate.

There’s a class of orbits called “polar orbits” that are sideways and perpendicular to the spin of the earth. These orbits are useful for satellites whose main job is taking pictures of earth, because they will cover nearly all of the earth’s territory over time. You get into a polar orbit by launching to the north outer south.

Aside from that, nearly all launches go towards the spin of the earth, because it’s a free boost. The fancy rocketry word for this is “prograde”.

The sun appears to traverse from east to west in the sky. This means that the earth is moving the opposite way: west to east. So if you want to take advantage of the free boost, the rocket needs to take off in an easterly direction.

The amount of spin you get is greatest if you launch from the tropics near the equator, and it falls off at greater north or south latitudes. In theory, if you set up a launch pad at the north pole, the spin boost would be zero in all directions, because you’re just rotating in place. At the equator, the free boost is around 1000 mph or 1600 km/hr.

So the ideal launch site is as close to the equator as possible, and it has low population off to its east, in case the rocket blows up or crashes. The United States has two sites that meet these criteria: one in Florida and one in extreme south Texas. Both of these face an ocean to the east. Europe launches Ariane rockets from French Guiana in South America. Russia uses Kazakhstan, which is on the southern ends of the old Soviet Union.

It’s probably fully recorded. Everything in and out.

That way if there’s a mishap it’s possible to go back and reconstruct the entire sequence or to replay high fidelity simulations of the network traffic at the equipment to reproduce problems.

There was a book a while back called Guns, Germs, and Steel that delves into this topic.

The root cause, as I understand it, is that Europe is on a continent oriented east-west instead of north-south. And Europe in particular is on the part of that continent that has a lot of easy access to the sea.

East-west orientation allows you to transplant plants and animals long distances and keep them at roughly the same latitudes, which means roughly the same climate. That is a big boon for spreading “civilized” agriculture, which is what creates surplus of labor, which creates non food jobs that advance technology.

Among the common 5-7 domesticated food animals people eat today, all but one or two were domesticated in Mesopotamia, but then spread all over Europe.

Access to the sea is the other component that turns tech advantage into colonialism, because it gives the transportation. Even today, China and Russia are great powers, but they are forced to be continental powers instead of maritime powers, because nearly all of their coast lines are hemmed in by narrow seas that are easy to blockade.

There are, of course, a bunch of other factors I’m not even thinking about and competing opinions. But I don’t for one second think that any of this has anything to do with European “innate intelligence” or skin color.

The Federal gov in the US has a “road legal” standard for commercial motor vehicles like trucks and buses. The feds also have minimum rules for headlights, brake lights and turn signals on passenger cars.

Everything else in terms of road legality is a state law in each of the 50 states.

The reason is the Constitution gives the feds power to regulate interstate commerce (i.e. big commercial vehicles that frequently cross state lines). The feds do not have the general “police power” that states have to pass laws on whatever.
