There are "planets". 8 of them.
Then, there are a bunch of "dwarf planets" - Pluto, Ceres, Eris, etc.
"Minor planets" - there are thousands, millions, I'm not sure, but a lot of these.
"Exoplanets", let's divide these into two categories - system exoplanets, that orbit a star like our planets, dwarf planets, and minor planets, and systemless exoplanets that do not orbit a star.
These are all different kinds of planet. In astronomical terminology, the word "planet" by itself is reserved for the Big Eight, but all these other things are a kind of planet.

The money's gone. It was given to the previous generation. How do you stop a pension system where each generation pays for the previous one, without one generation getting a raw deal (they paid for the previous generation, but don't get anything themselves)?

My dad and I wrote a BBC BASIC interpreter for PC-DOS. I'll have to dig it out and see if I can get this working in it.

Who is Steve Job?

Because it can cause embarrassment to the company to admit that their software is in peril. Maybe this guy doesn't have the authority to make announcements to the public on behalf of his employer.

for a business like yours!

That's not an ethical issue, it's a moral issue. I see no ethical difference between a sperm and egg that have not combined, and a sperm and egg that have combined and undergone a small number of cell divisions. In my opinion, until it has neurons that are firing, there's no ethical dimension.

No, he probably won't, because a rape threat to a man is very different to a rape threat to a woman. Just like a racial slur levelled at a white person is very different to a racial slur levelled at a black person, and an mental capacity jibe against a neurotypical person is easier to ignore than one at an autistic, cerebral palsy, or downs syndrome person. In all three cases the first is easy to brush off and ignore, the second not so easy.

Not all segregation is sexist. Women-only gyms, all-girls schools, female sports teams and competitions, none of these are ghettoes that women are forced into.

I know that "public" has opposite meanings in the UK and US, but I didn't know "private" did. Her school is independent, as in not state-owned. It's a charity. And I don't see why it's ironic. "Girls should have the right to get an education" and "Education should only be provided by the state" are two entirely orthogonal statements.

Where did that come from, and what does it have to do with women being attacked just for being women on gaming forums? "If you want to have the right to campaign to get Jane Austen on British banknotes, then you also have to be prepared to burn a Koran" is something of a non-sequitur.

Sexism is just a tool that the trolls use where appropriate. It's all about personal power. For example, one of the trolls sent to jail for harrassing Caroline Criado-Perez was a woman.

I disagree. If a small group of trolls are being trolls, and you "do your best to avoid being a target", they've won. A small group of trolls have had a chilling effect. We need to do more to uncover and punish that kind of behaviour. And, was Kathy being obnoxious when she was targetted? I don't see any evidence of that, and even if she was, I don't care. That's no excuse for death and rape threats.
The thing that astonished me most about trolling is, there was a case over here (UK) where someone was targetted with rape threats for organizing a campaign to get a woman onto our banknotes, and one of the trolls sent to jail for it was a woman. Which tells me it's nothing to do with sexism, and all about personal power. Sexual threats are just a tool in the box.

Knowledge of a variety of programming languages, even if some of them are dead, will always help. Even if it's just in "I remember when Perl was still a thing" bragging competitions.

Sure, I agree, I'm just explaining where the attitude comes from. If global warming really is the threat that some people believe to be, then the danger may seem to be too great to be calm and polite about. And that doesn't help, because as you say if you act like a raving loonie then people will treat you as a raving loonie. It doesn't get the job done. "We", those of us who think that warming is a real threat, have to take the risk of taking a softly softly approach to addressing a desperately dangerous threat. And that's difficult. Put any animal in a life-threatening situation, and the instinct is to bare the teeth and snarl.
