I guess they just didn’t test those of us in country towns too far from a selective school!

I was a gifted kid schooled in NSW. My kid was schooled in QLD. I’ve never heard of these gifted schools.
- Comment on Would a disk shaped planet have uniform gravity like earth or would it vary depending on whether you're near the center or edges? 1 week ago:
Yep, as are solar systems. But when they collapse in to single objects, those objects end up spherical once they’re about a third the size of our moon (or even less than that if they’re icy/gaseous).
- Comment on If you had procreated with an opposite-sex clone and produced a child, would that child also be a clone? 2 weeks ago:
The Y chromosome doesn’t carry much of anything. It’s basically just a carrier for the SRY gene, and in most cases, it’s that gene that triggers the majority of the sexual differentiation that occurs in early development. The actual “code” for what develops and how it develops is there for male and female differentiation in all humans, and it’s hormones and other factors that control whether or not that genetic code is expressed.
And in this case, we’re talking about stem cells (ie, a cell that has the potential to develop in to any cell, but hasn’t yet done so), and then artificially triggering those stem cell to develop in to sperm cells. A trick that can be done because the genetic code for it to do so is already there if the conditions are right.
As an aside, this is also why hormone replacement for trans people lets them develop secondary sexual characteristics that they wouldn’t otherwise develop. The code was already there, it just takes the right trigger to get the code expressing (in this case, hormones)

If not exactly identical, would they be like twins?
The parents? Basically, as the only difference between them is a single chromosome out of the 26 we carry. There are slight genetic differences between identical twins, due to the accrual of mutations during cell division, but it’s smaller than a full different chromosome. That’s splitting hairs though, because both identical twins and our theoretical clones would be functionally identical.
If not exactly identical, would they be like twins?
If you mean the parents and their child, then they’d be somewhere between identical twin and regular sibling in terms of genetic similarity. Regular siblings on average, share about 50% DNA. Identical twins share 100% DNA. Our theoretical child in this scenario would share around 75% of their parents DNA

By definition, two people of different sexes can’t be clones
- Comment on Would you rather be reincarnated into a world of magic or reborn as yourself (with your current knowledge fully intact)? 2 weeks ago:
In that case, I’ll take “reborn with current knowledge intact” thank you!
Even though magic sounds tempting, if I can’t remember my previous stint, my reborn persona may as well be a completely different person!
- Comment on Would you rather be reincarnated into a world of magic or reborn as yourself (with your current knowledge fully intact)? 2 weeks ago:
Unless the magic comes with sex and gender fuckery spells, neither. I’m not really keen on doing a whole lifetime without access to trans health care

- Comment on Is there a fediverse service that access most fediverse networks? 3 weeks ago:
They’re also front ends. They don’t give you a single universal fediverse account that crosses fediverse platforms
- Comment on Is there a fediverse service that access most fediverse networks? 3 weeks ago:
Yeah. It feels like software from a previous generation that has cool functionality, but just doesn’t have the usability it needs to be the center of a daily fediverse experience
- Comment on Is there a fediverse service that access most fediverse networks? 3 weeks ago:
Friendica.
In theory, it’s perfect, and just what I think the fediverse should be, but it’s terrible to run as an admin.
- Comment on Where has the "www." gone? 4 weeks ago:
There’s two things at play here.
First, www originated in a time when the web was not synonymous with the internet. Gopher, FTP etc were a much larger part of peoples daily internet usage, and servers would have different subdomain names to account for that. ftp.tld.edu, gopher.tld.edu and www.tld.edu were all domains you might see for a single server for example. Then of course, the web grew, and the other protocols became less relevant, but the www stuck around. One of the reasons you’re seeing less of it, is because that tradition is slowly fading away given its loss of daily relevance.
The other reason you’re seeing less of it is that browsers often just hide it even when it’s there. And that of course, will create more future instances of servers just dropping it completely.
- Comment on Ate there more galaxies in the universe, than stars that can be seen from Earth with the naked eye, or with a telescope? 4 weeks ago:
There are about 100 billion stars in our galaxy. There are about 200 trillion galaxies in the parts of the universe that are observable from earth. Which is to say, galaxies outnumber the stars in our galaxy by about 20 to 1.
If we limit it to stars we can see with the naked eye, then instead of 100 billion stars, you’re down to something like 5,000 to 10,000 stars depending where on earth you are observing from. In which case galaxies in the observable universe outnumber the stars we can see about 20 billion to 1.
- Comment on Why does auto focus work so poorly when trying to take a picture through smudged glass? 4 weeks ago:
Oops, sorry, I assumed you were talking about a smudge on the glass of the lens, not a glass window.
In the case of a smudged glass window, that’s an issue for both types of autofocus, and it occurs because the glass is closer than the subject you’re trying to focus on. And due to the way the physics of light work, it’s easier to find focus on closer subjects than distant subjects, for the same reasons that your depth of field increases the further your focal point is away from your sensor. And because the smudge itself is something that provides sufficient detail for autofocus to work, if the smudge will often become the target of the autofocus.
There are a few ways of dealing with it though. You can step closer to the glass, so the smudge is within the minimal focal point distance of your camera. If it’s too close for your camera to focus on, it won’t accidentally focus on it. You can also change the active autofocus points on your camera so the smudge under an autofocus point. You can also drop the camera down to one autofocus point, move the camera to focus on the distant target without the smudge in the way, then half hold down the shutter button, and then reframe the shot whilst holding the shutter. That will keep the focal length set to where it was, but it won’t actually take the photo until you press the shutter the whole way in

Nothing, because that’s not what happens.
- Comment on Why does auto focus work so poorly when trying to take a picture through smudged glass? 4 weeks ago:
It depends on the camera and the method of auto focus it uses. Older cameras and cheaper modern cameras use contrast detection, that alters the focus until the edges of an object in the focus zone are as contrasty as possible. The smudge makes it harder to find clean edges on the subject.
Old school dSLRs and modern mirrorless cameras often use a different, faster method of auto focus called phase detection. It’s more expensive, because it requires specific hardware to work. Either way though, phase detection has the same problem. It uses two different sensors (or a single hybrid sensor) to split the light coming though the lens and overlay the resulting images. When the images are identical, the image is in focus. But because of the way this system works, smudges don’t really stop the auto focus from working. The smudge will still reduce the contrast and crispness of your final photo, but you’ll still get good auto focus.
- Comment on [META] Overseas News - Proposal for increased enforcement of Rule 1 5 weeks ago:
Honestly, I’d like the seppocentrism rule to be more specific. Unless it’s explicitly related to Australia, I don’t want to see US related news in here at all.

What’s to worry about though? Remember before you were born? It’s going to be exactly like that.
I mean, I don’t want to die, but I also don’t understand what there is to be anxious about.

- Comment on Is this a scam or am I being paranoid? And if so, what kind of scam is this? 1 month ago:
It’s called remote deposit cheque fraud. It’s a fake cheque. If you cash it, it will eventually get flagged as a a fake, and the bank will take the money back, even if you’ve already spent it or sent it to the scammer. And if you never send money to the scammer, they get nothing, but it also costs them nothing to make the attempt, because you’re the one depositing the cheque and wearing the risk.

- Comment on Why are some Linux community so toxic? 1 month ago:
The same thing happens in trans communities, but the answer isn’t for the old guard to try and handle everything themselves, burn out and then shut down newbies that are looking for community and help.
The answer is for the crusty old guard to create the space and keep the worst offenders out, whilst letting the people that aren’t burnt out support each other and keep the community thriving.
Sometimes that means letting common questions be common, because if you’ve got a positive community, someone will always be there with an answer and a link to an even more detailed resource.
