QOTO Announcements & Polls @QOTO@qoto.org

#QOTO update:

We recently added a new service to the QOTO family of services. We now host a Discourse server are https://discourse.qoto.org

It is currently empty but will act as a space for discussion around open-source STEM projects or general STEM discussion. It will also act as a mailing list for any project managers who wish to use the service for their projects.

IT compliments our other services well including a GitLab instance open to the general public for open-source STEM projects as well as for our users to host private or personal websites.

We also have a NextCloud server open to the public for open-source STEM projects and individuals to utilize as well.

In the next few weeks we will continue to bring up new services including PeerTube, Pixelfed, FunkWhale, and many more on their way.

@ashwinvis Sorry just saw this. As mentioned @QOTO is not an active account it only produces announcements.

We share the link to QOTO publicly on github and post it to our users. While the GPL does require you to post the source code and share it, it does not require it to be explicitly linked to via the source code link. We however link to it elsewhere. Anyone who cant find the link Can be given it on request.

With that said despite not being a violation I will update the source code link itself int he next release just in case it causes any confusion. thank you for the update.

@socrates

@modulux Correct!

I’m thinking of 5 numbers such that their mean is equal to their median. If 4 of the numbers are 14, 8, 16, and 14, what is the 5th number?

Please CW answers and hints in your responses.

Interesting fact of the day: Diamonds are flammable

@njha I'm going to try this again but with a base mass for the ship itself in addition to the fuels weight. I'll play with different numbers to make sure it gives sane results but I think that should do the trick.

@SnDer

Ok so i made a mistake on this problem. Turns out this was accidentally a trick question. The answer is that any amount of fuel will get you to any height. The reason being that as the fuel is expended the mass of the ship approaches 0, so acceleration approaches infinity. So by the time the rocket is out of fuel it would be moving at the speed of light no matter how much fuel it started with.

As suck I will post a new version of this question and ill make sure i solve it BEFORE I post it.

@SnDer @njha

== Math Problem of the Day ==

If you have a rocket traveling vertically with only the mass of its fuel to carry, with earth sea level gravity, then, how much fuel must you carry to reach a height of 1 kilometer if maintaining a newton of thrust uses up 1 gram of fuel per minute.

Bonus: show the equation with height and fuel per time are both unknowns (variables).
