look up the life and times of Edward Teach.

Precisely.

This is Izzy, aka Her Majesty Queen Isabella Greypelt, Isabella Busy Boo, Izzy Boo, Busy Butt, and The Monochromatic Quadropus.

This is Miss Chiff, aka Widdle Bit or Tiny Tux. She weighs 8 pounds and she hates everyone except my mother.

30 knots indicated would take a plane out of the sky too, that’s well below most airplane’s stall speeds. We can probably fix that before doing the Monsanto Slam though.

I don’t know, the smallest computer I have in operation is the sketchiest one.

The computer can’t be held accountable, but the programmer and operator can.

I could go on a whole thing about mission rules and command decisions here, but I’m sick of typing for the day.

Things like Minetest exist.

Fun fact: In several episodes of the original Star Trek series, Spock can be seen holding and using an E6B flight computer, which is a slide rule invented for the US Navy in World War 2.

By definition.

Putting my flight instructor hat on here, this is mostly correct.

“Indicated airspeed” (IAS) is what number your aircraft’s airspeed indicator is pointing to. As Rivalarrival described, the airspeed indicator is a barometric instrument that compares ram air pressure with static pressure to measure the dynamic pressure, which is a function of airspeed. Indicated airspeed is an indication of how the airplane will “feel,” how much force will act upon the aircraft in maneuvers, which is why force limit speeds such as maximum flap and landing gear extended speeds, stall speeds, max normal operating speed and never exceed speed are marked on the airspeed indicator.

“Calibrated airspeed” (CAS) is indicated airspeed corrected for instrument error. The airspeed indicator and the plumbing it is hooked to aren’t perfect, so they’ll be off by a few knots especially near the lower edge of its range. You find a chart in the POH that says “IAS 45, 50, 55, 60 etc” on one line and “CAS 43, 49, 54, 60 etc” on another. Pilots use this for, if we’re being honest with ourselves, nothing.

“True airspeed” (TAS) is indicated airspeed corrected for air density. The airspeed indicator is flawed in concept: It’s a pressure gauge calibrated in units of speed. To actually determine the relative velocity of the aircraft through the air, we have to do a bit of math comparing the outside air temperature with our pressure altitude, this will give us our density altitude. You then do a bit more math to correct calibrated airspeed for density altitude and get true airspeed. E6B flight computers have little windows for this.

Here is my old cardboard E6B from when I was a student. I’ve set an air temperature of -40C over 30,000 feet in the right-hand window, the center window is showing…pretty much exactly 30k feet of density altitude, and we can read true airspeed over calibrated airspeed on the A and B scales. So for 100 knots, we can look at the 10 on the B scale, and read about 164, maybe 165 knots on the A scale. At 30,000 feet and +50C, which literally never happens, your density altitude is ~38,000 feet and 100 KCAS will get you 194 KTAS. Not quite 400 😜

“Ground speed” is true airspeed corrected for wind. To calculate your ground speed, you need your true airspeed as we just calculated, and winds aloft forecasts from one of the government agencies the Republicans are desperate to destroy, and then we do some trigonometry. You can whip out your Ti-83 Plus Silver Edition from high school and SohCahToa this bitch, or you can flip the E6B over to find a handy dandy vector plotter, which does ground speed and wind correction angle calculations by accurately drawing and measuring the triangle. My high school physics teacher called using this thing “cheating,” I call it “a required aeronautical skill.”

I always appreciate the girls who go to conventions cosplaying as PS1 era Lara. It’s not a difficult costume to source, you need a pale blue tank top, brown shorts, brown boots, fingerless gloves, a little backpack, the pistol belt with the huge square buckle, and half a shoebox.

Mechanical/civil engineering software, music production, and digital art. Those are the big ones.

I mean, I’m going to invite everyone of every age to strip bottomless, take any “back in my day we didn’t have your fancy [whatever]” bitching an moaning you have to do, dip it in honey, roll it in sand, and cram it up your exposed ass.

I’m 38. In my mid-20s, I taught flight school, mainly to people twice my age, and this included a fairly large section on reading Sectional Aeronautical Charts. I’ve got zero fucks to give for someone 7 years my senior pulling “back in my day we had maps” shit.

I’ve been looking into robotic lawnmowers, and they’re basically the same. The more primitive ones have a hall effect sensor under their snout feeling for a wire you bury around the edge of your yard, and do the “go until you hit something, turn a random amount, repeat until low battery, follow perimeter to dock” or they require phoning home in some way, shape or form.

Meanwhile, some guy’s got an open source system that runs on a Raspberry Pi on the mower itself.

I guess I’m willing to believe that some of the LIDAR or camera-only guided mowers need some serious processing power to create the maps they use for guidance around the yard, and that’s more practical to do on the company’s servers than on the device itself…except not really; we’ve got decently powerful ARM SoCs that don’t cost much, don’t take a lot of power to run, and can do that job. The reality is, you can’t get a pedometer app for a smart phone that doesn’t broadcast sensor telemetry to two continents these days.

I remember watching an old Tim Allen stand-up set, he was talking about ordering a bench grinder from the Sears catalog. “Six to eight weeks later” it arrived.

it’s like they use Youtube’s algorithm. Sure, the last 15 minute planetary astronomy video was cool, I’ll watch another.

Doesn’t work as well with material goods.

It’s pronounced “gulp-noo”

WINE is true, it Is Not Emulation.

The one I hate is LAME, which definitly IS an MP3 Encoder.
