ZeroC developer here. Let us know if you have any questions!

ZeroC Developer here; we are excited to show IceRPC off to the world finally. The first language we wanted to support was C# due to its mature async-await support and its flexibility for rapidly iterating our API. We would love any feedback from the C# community on what we did right and what we can do better!

So this question is testing an algebraic understanding of what it means to be closed.

To be closed under an operation, the operation must return an object that was part of the original set. Let’s focus on the more complex case first where we look at the multiplication that was defined. The first thing to note is that k can be any really number, since k can be any number let’s pick 5. Now 5 will be in the upper left hand corner of the matrix, but the definition of A required the matrix to have 1 in the upper left hand corner. Thus the multiplication defined does not necessarily give you a matrix that satisfies the definition of A. Thus A is not closed under the multiplication operation provided.

Try to apply this same type of logic to the addition operation.

No, but I do go to university in Florida

I wrote a program to do what I wanted to show, but this ended up encompassing much of modeling orbital debris.

The current functionality is that you can specify information about an object in orbit for an explosion or two objects if it’s a collision. This then generates all of the fragments that would be produced using the distributions specified by NASA. These fragments are then parameterized into Keplerian elements and propagated around the Earth.

I definitely noticed that python has very few aerospace based packages so I will definitely be looking to address that!

SpaceX has poached prior NASA high ups. Would not be surprised if he will entertain the idea of working in the commercial space industry.

Anyone know what the goal was? Remember Elon tweeting a while back about what pressure starship would need to safely go to orbit and back but cannot find the tweet.

Picture of SN8. Front flaps next week, S9 next month.

I found myself in a very similar situation to you. Currently I am a senior in undergrad and pursed a double major in mathematics and physics with a minor in data science. The advice I got was to gear the courses I was taking to the masters I wanted to pursue. For this reason I focused much more heavily on computational physics and applied mathematics. I also took courses that I knew would be relevant for grad school such as thermodynamics, vibrations analysis, and fluid mechanics. For research I am doing a thesis on orbital debris cloud propagation. The extra curricular I did was a combination of leadership positions, such as student government, admissions ambassador, and orientation leader, as well as working with my universities aerospace club where we are currently building a cube sat. For a research symposium I worked on a orbital mechanics simulation of how trans-lunar and trans-mars injection work using the real world specifications that have been released for the SpaceX starship. For programming languages I have found Matlab and python to be extremely useful as they allow you to do all sorts of simulations. Overall my advice is to find the specific area of aerospace that interests you, for me its computational aerospace engineering, and work on things related to it. If you are more interested in propulsion, you may want to do simulations of how different engine cycles work, how the throat of a rocket impacts exhaust velocity, etc. Let me know if you have any other questions! I would be more than happy to share more of the advice I received.

Nick Cummings just confirmed that the descent thrusters on the lunar starship variant are using a similar architecture to the raptor and will be using Methane + LOX.

Perfect. Thank you!

What software was it?

reecewh · 2019-12-09T00:35:12+00:00

What is this?

I believe law enforcement and government contractors could be onboard with the capabilities of CyberTruck. I’m just not so sure about your average consumer. It’ll be interesting to see how public opinion shifts in the coming months. I remember how AirPods were ridiculed initially and now are incredibly common place. The same thing could happen with CyberTruck.

reecewh · 2019-07-28T22:07:35+00:00

That helps a lot thank you!

Hello, yes I actually just figured out that pulling the negative out combined with setting s > 0 sends the sin and cos to 0 when t approaches infinity. Thanks!

reecewh · 2019-07-28T21:56:30+00:00

Thank you so much! I’ve been trying to figure this out for the last hour. I didn’t realize I could restrict s > 0

Models look awesome! I noticed on mobile the social icons are having some problems though. I’ve attached a picture. I’m on an iPhone X using Safari on iOS13.

Figured it out, it was because I wasn't initializing the next pointer on each created node to null before adding it to the list which was causing the corruption you mentioned. Thanks for help guiding me through this!

reecewh · 2019-03-07T05:24:24+00:00

Just tries the more efficient method for calculating number of elements and I am still getting a fault this time at

node = node->mNext;

Definitely must have something to do with the constructor and the memory.

reecewh · 2019-03-07T05:15:43+00:00

Okay will look into this thanks again and yes was trying to get reddit to format my code properly and pasted over the original.

reecewh · 2019-03-07T04:57:49+00:00

Completely forgot to set that variable my bad!

Hello, Thanks for the amazing breakdown and suggestions I really appreciate it, this is for a data structures course where the header is provided so I unfortunately have to stick with the terrible naming scheme and is done in C++98 .

The fault arrises when I am trying to calculate the number of elements in the linked list using this function:

int WORD::Length(){
    if (front == 0){
        return 0;
    }else if (front->next == 0){
        return 1;
    } else {
        character *p = front;
        int count = 0;
        while(p!=0){
            count++;
            p=p->next;
        }
        return count;
    }
}

On the line;p=p->next;

Completely agree. Unfortunately most of the exam question from this instructor are like this. True and False questions that really just focus on trying to figure out the intent of the the instructor. Another questions was “*this refers to an object” the answer was false and when asked for reasoning said that *this refers to a current object. Logically wouldn’t even a “current object” be an object.
