Which is why we should leave it on during the winter too.

I just want it to always be DST, I hate getting home after work to only have an hour to take care of things outside before dark.

Ah. So yeah like the other person said those static blades are stators. I havent found a good name for the cone aside from “aft cone” but that’s more for turbines. The stators should help it make pressure (that’s what they do in turbines) but the only reason I see for the aft cone is reduction of turbulence and since this is for cooling the hot end turbulence is actually a positive thing because it reduces the skin of hot air that sits against the heatsink fins.

If you’re pusing enough air you may benefit from a nose cone but it should probably be more hemispherical. Also an intake cone that’s like a trumpet bell might be beneficial.

For noise, most is probably in the blades but you may see some reduction by adding a sweep to your stators and/or adding a jaged pattern in some places like all the new jet engines do. Like this: https://www.nasa.gov/wp-content/uploads/2015/03/qtd2_sunrise_3024x2016_0.jpg

Granted, on the scale we’re talking here all of this will be splitting hairs.

What exactly are you trying to do, if you don’t mind my asking?

Just trying to quiet those loud fans?

The cone shaped hub in the middle? Same reason you’d see a pointed nose or tail on a plane, to reduce drag and turbulence and possibly noise. With some fans it doesn’t really matter but at high enough flows it’ll become worth it to spend the extra money on that part to make it cone shaped.

Look at airplane propellers. On them that part is called a spinner. On an old, slow, biplane with tons of cables and other draggy parts, it likely wont have one because it’ll make no difference anyway. But on anything that’s the slightest bit sleek you’ll have one because it will significantly reduce drag.

Focal length and aperture both affect how much focus matters.

Also with most regular cameras, from what I’ve heard they actually have their max focus slightly past infinity to account for thermal expansion so the general advice for doing astrophotography is to focus on the subject, not just whacking it to infinity.

Those spy satellites are focused at the distance of earth. Hubble is focused at infinity or near-infinity.

You’d just get some really blurry images.

Closer but still looks a little more “in the know” than DiCaprio

No, the Fire TV Stick is a streaming stick. The Fire TV is a TV with the stick built in and it makes you go through the Amazon Fire UI to do normal TV things as well.

Planing vs displacement.

An aircraft carrier is limited by its hull speed to about 45 pretty much no matter how much power you give it.

A slow jetski will do 65. I’ve heen on ones that would do that with the “slow” key where supposedly the fast key would let you do 85-90.

I’ve also been on a tri-tune that did 75.

An aircraft carrier is about the fastest displacement vessel but when you move into planing hulls its a different ball game.

I can shoot a pistol from a jet-ski and go faster than an aircraft carrier. Is that a ship?

They’re vessels but I don’t think they’d qualify as ships.

If I ask you to name every ship in the Navy I do not want RHIBs, dinghys, tenders, lifeboats or rafts included, but if I ask for every vessel, then if the Navy owns a kayak I want it listed.

Need to photoshop that last one way sign to point both ways.

And stick a random one out in the field barely visible with no arrows.

So roughly like $6.50/gallon.

I went on a trip recently and the lowest price I saw was, I think, $2.69/gallon which is like $0.70/Liter.

You could even automate that entire process.

Require customers to email support, require a log file, have your log files show if mods are installed, auto reply that the customer should reinstall the game without mods and see if the issue persists.

It looks like a garage with a house attached to it rather than the other way round.

My dream house is 80% garage/workshop.

But yeah, this one looks strange. I think because the garage juts out forward.

Yeah but the CO2 is very much going to encourage you to leave. If you breathe 50% CO2, you're gonna know it.

Breathe Halon and I think your voice will get deeper but you won't be in pain.

Halon Injectors. That shit will put out anything…including people which is why it's banned.

In the summer, at night, we’re facing the galactic center. You can see the cloud of uncountable stars held close to the supermassive black hole at the center, and you can see the band of light spanning the sky that it the rest of the disk and arms.

It’s the reason the galaxy is called the Milky Way, because those billions of stars looks kinds like somebody spilled milk all across the night sky.

If you are in the darkest parts of the world I think you can still see it a bit in winter but you’re looking outward into intergalactic space, so it’s much fainter, only showing the stars in our arm that are even further out.

I was ready to see the Milkyway in Colorado a few years back but there was wildfire smoke covering the sky the entire time I was there.

I did get to see it just a bit in Arkansas last year(it really wasn’t as dark as I’d have liked it). I was doing some long exposures with a camera and my mom says “Wow it’s a pretty clear night except for that one cloud…”
