dmarc tells you about false positive, not false negative. if you send mail from a dmarc server, it will be more likely to reach its target.

So MongoDB is now an alternative to Linux?

the point of the poster before you is: most propably your girl/boy will like this stuff. YOU may think you want to press her/him into another role, but the toy manufacturers do not care about "wanted" roles, but about stuff that will be liked and bought. So the selection of items in the store is quite a mirror of the demand.
Maybe your little girl/boy does not like it, but there is a big propability (s)he will, if you ask her/him.

(Sorry for gendering the whole post, but here it seems apropritate)

You may discuss, if you really need to get people into something, they would not consider themselfes. If you want them to try it anyway, it's a good idea to make it somehow compatible to their current interests. So if you discard the "girl focused" toys, you will not reach the girly girls (while the tomboys will use the boy tech-toys anyway). So there is some purpose in it. If they will stay longer than needed for seeing "okay, it starts girly, but then it gets seriously STEM, which is not my beer" is another question. The tech women i know have no problem to use standard tech without womenizing it first.

they want you to use a mircrosoft account instead of a local account. you pay with your data.

and in facebook you have a profile picture. so you point is ...?

why should we even have a policy of one account per person?

tells us anonmous coward.

seriously, there are a lot of idiots on facebook posting with their realname. more idiots than the pseudonymous users of some other websites.
"real" identity is NOT a reason not to post something.

and it's a basic right to be anonymous.

In germany every service MUST provide the option to use it pseudonymously, if there are no real reasons against it (like a shop may ask for your real address).
This holds for facebook as well ... facebook just does not care about it.

oh, someone got a joke. congratulations!

they require your realname
they may ask you to prove it (hey, what site should be allowed to see any id documents? None!)
they may block you
you may use a pseudonym and feel clever, they can stop you anytime.

Do not use it. else your create a dependency. Lose all your contents / contacts or provide a real name? Good thing, i told all my contacts, how to reach me, without having facebook. So facebook cannot block me from contacting them.

Don't you think, the scientists know very well, what they need to test for depression/frustration, etc.? Neuroscience is their job, not yours. They will know their basics.

math gives you two limits, one being 0, one being 1.

you algorithm may take care of it.
This does not mean to set 0/0 = 0, but like "if(denominator == 0){converged=True}"

Infinity like java knows it is okay. this constant obeys the usual rules like inf + x = inf

1/1 = 1
1/0.1 = 10
1/0.00001 = 10000 ...
1/0 = 0

erm, okay. graph that function and ask yourself, can this be right?
