In order to account for binary systems, I like to generalize and say it's all the same although the formula to compute the actual center of mass when inside the larger body differs than when it is outside. This is because when inside the larger body, some part of the larger body modify the gravitational attraction from the smaller body.

But in the end, the important point to be aware of is the center of mass.

As a side note. although there is few references to such cases, it is the same for 3,4,5... body systems. All you have to understand is the center of mass.

Translated to slashdot developer like language: Understand the basic principles and avoid re-inventing the wheel as much as possible.

Congratulation!

Here is a link with a nice animated gif that shows it all:

Oh and yes, I already knew the center of mass was inside the Earth and both planets rotate around that center of mass which is pretty close to rotating around each other in popular language.

Hmm... a 4 meter wide body should be very close to negligible with regard to that.

Indeed, they rotate around each other, contrarily to popular belief where the Moon rotates around the Earth.

I recently had a dream where the Sun disappeared, Would that have any effect on earth?

Of course I know. When younger, I use to work outside and I had no myopia. Now I am older, I work underground and I have myopia. See? you can't deny scientific facts like that.

I work in a basement 200 feet under the ground and I know it feels good to get outside once in a while.

Don't worry I am pretty sure /. doesn't have a suicide prevention tool. It is far down the list after https/TLS support.

The project has been delayed several times due to a high rate of false positive. It is really difficult to adapt off the selves suicide prevention software to /. audience.

Of course you are right, but I find interesting that something as obvious as this is posted on /. You know, the obvious is often hidden more and more these days.

As for second languages, I master 2 languages fluently. I learned the second one at 18 using total immersion language learning. It is a shame that I never took the time to learn a third, fourth and fifth one or more this way.

I recommend total immersion for those wanting to seriously learn another language, you will experience what the poster is talking about even more deeply ;-)

Indeed, from a server admin perspective, my server is safer if it only runs http. https/TLS is meant to prevent user that have access to the traffic to sniff it which is a different topic. I am not sure if the president is aware of this but hey, I hear plenty of things like that every day.

I already installed STARTTLS on Mrs. Clinton mail server last week.

You need a WAF these days. I use mod_security. It can save your arse from zero days sometimes.

this scales much better:
$IPTABLES -I INPUT -m set --match-set ipbl src -j DROP
$IPTABLES -I FORWARD -m set --match-set ipbl src -j DROP
$IPTABLES -I FORWARD -m set --match-set ipbl dst -j DROP
$IPTABLES -I OUTPUT -m set --match-set ipbl dst -j DROP

add an ip to ipbl set:
ipset add ipbl ${IP}

don't forget to block all ipv6 traffic if you don't need ipv6:
${IP6TABLES} -I FORWARD -i eth0 -j DROP
${IP6TABLES} -I INPUT -i eth0 -j DROP
${IP6TABLES} -I FORWARD -o eth0 -j DROP
${IP6TABLES} -I OUTPUT -o eth0 -j DROP

Can they mount Linux partitions on these mount points?

Thank you, Thank you.

I do not know how to thank you enough for this advice, I am going to make use of it from now on.
