BMW is a classic from my time at USAFA. It's a great book and ideal for those beginning in Astrodynamics.

I bought it from an upperclassman for 25 cents.

Still on my shelf and I used it to design my own astrodynamics course to teach during grad school.

I'm interested and considering getting an amateur radio license.

It's not clear yet, but I wanted to get a single portable device that allows for reception of all the most important frequencies, which I think includes shortwave, HF, VHF, NOAA weather and the amateur radio bands.

Is there a device that does all of this?

Not sure what other people do, but I always publish at a journal then put my manuscript on arxiv, or whatever field equivalent, and then on my personal website.

Then I submit it to scihub.

Best we can do these days

This is relatively simple to create yourself.

There are closed form equations that can be used for the angular position of the sun, which will be more than accurate for this purpose.

Then it's mostly some simple trig to determine areas that have a line of sight to the sun.

I have this on my to-do list because in my bedroom on a full moon the light will come through one specific window onto our pillows. i wanted to automate either curtains or something to predict when it'll happen.

Maybe eventually I'll get around to something like this

I will say that at multiple job interviews people have commented and been impressed with my LaTeX CV.

So it's a plus!

I want to track sex. So far it's been a spreadsheet.

Is there anyone else with a better method?

I think what they are referring to is "angular momentum dumps". The reaction wheels have a fixed maximum amount of angular momentum. This is a function of the speed of the wheels themselves since the mass/moment of inertia is fixed.

Over time external forces continue to add momentum to the system (from drag/solar radiation pressure). In order to maintain a desired pointing direction this means the wheels must increase in velocity to "absorb" this momentum.

Eventually you need to "dump" the momentum using another external force, such as thrusters, or in this case the same solar radiation pressure.

Goal is to orient spacecraft such that external forces can be used to spin down the various reaction wheels, thereby "dumping" momentum out of the wheels.

This is pretty common on all spacecraft, but gets complicated/innovative when you have to do it in an emergency or if you don't have a full set of reaction wheels.

vim-fugitive is my goto

I think that 1800lbs is actually the weight capacity of the truck if I'm reading the article correctly.

I'm trying to find the mass of the battery to compare the energy density to the Tesla battery packs

Can also use a router integration. I have a mikrotik and it tracks DHCP clients which I use for presence detection using a bayesian sensor

I'm not an expert and have forgotten most of my aerodynamics classes but I believe it's related to shockwave formation on the wing tips or possibly pitot tubes to measure airspeed as a function of pressure changes

Another USAA member here. I haven't had to do an auto claim yet, besides simple windshields, but have had several property claims.

They have been great. In fact, right now USAA is in the subrogation process against the offending party for a claim on a bicycle.

I've been happy with their insurance products, their even better customer service, and have no plans of changing.

Still protected by the math?

All the three-letter agencies already knew they had these tools available, GPG, veracrypt, Signal, etc.

Now it's just impossible for governments to whole sale eavesdrop on conversations. If they want access it now has to be targetted, and most likely device specific which is harder.
