Comment Declining fertility years and culture (Score 1) 176

One explanation is in the rise of women in careers and education.

A woman has roughly 16 years of fertility, from age 14 to 30. At age 30, 10% of couples can't conceive after a year of trying and the numbers get worse after that. Yes, older couples can have kids, but the probability goes way down.

Culturally, having a child before age 18 is assumed to be a bad thing (4 years). Then if the woman has a college education (another 4 years), then goes for an advanced degree (up to 7 years), or wants to establish herself in her career (5 years?), or wants to work off some of the college debt (5 years), the remainder of her fertile years is not enough for population replacement.

It's largely the same for men, at age 22 they may want to start a career and pay off some college debt for several years. Men can father a child at any age, but by and large they tend to marry people roughly their same age.

It's also harder to raise a family in an apartment than in a house, so for both parents it may "make sense" to work for several years to save up for a house.

(Don't take this the wrong way, I personally feel that women should be in colleges and have careers, I'm just pointing out the conflict of interests here.)

It would seem that culture has to change somehow to allow (encourage) couples to have kids earlier, but I'm not sure how that would work given our current economic system.

Imagine a black unit cube cake with white frosting. Take a knife and cut out pieces of the cube to make a black hole outline within the white frosting. When you do this at an angle to the sides, it turns out that a cube 6% larger than the original cube can pass through the outlined hole.

All the platonic solids have this property, along with a lot of other polyhedral solids.

It is absolutely incredible how people are unable to just... stop... and do nothing... and think to themselves... and just sit and enjoy the scenery nowadays.

I live in a quiet rural town precisely because it allows me to do that. But during lockdown, I heard NOTHING but people saying how they were going insane and "had to" break the law/quarantine in order to go out and do stuff and meet up with people after just a few days. They literally couldn't be in their own company for a few hours without going mad.

When the time comes to choose some Mars settlers, I hope we chose from the people based on their reaction to lockdown. Even supposed scientists went apeshit at each other in those biosphere projects.

You could send me to live on Mars on my own to terraform the place and the only time I'd get pissed about that would be if others came and tried to set up camp near me.

It's a website run mainly by one guy....

"This website was made by Thomas Bloom, a mathematician who likes to think about the problems ErdÅ's posed."

It's not like an official website endorsed by the author or anything. It's just a website of a guy who has some interest in that particular set of problems.

"Is the database up to date (e.g. the open/solved status of each problem)?
No, but that is the eventual goal"

It's like holding some trainspotter responsible for not knowing about the existence of a particular niche train somewhere in the world.

Comment Are those solid state drives? (Score 1, Insightful) 23

At 2013, the disks in question were spinning disks. I didn't understand from the article whether the stats for 2021 and 2025 were about spinning or solid state drives.

Comparing reliability over time of spindles to solid states is almost meaningless. The failure scenarios are just not the same.

Oh no... they'll just have to... patch their firmware like every other manufacturer has had to.

For those people who bought a Framework laptop, enabled secure boot and rely exclusively on that to protect their computer from booting into an unauthorised operating system.

P.S. their firmware page currently have 11 CVE fixes listed for the lasted firmware.

This is inevitable.
This is how manufacturers should do things.
It's really not even that important.
Making an article about it is scaremongering.
I don't see an article every time Dell has something like this, or Asus, or HP, or ...

Two questions:

  1. Did you have a choice? Was there an option, maybe even a more expensive one, that did not include the lock-in?
  2. Is the company where you signed the contract a monopoly?

Because what usually happens is that you don't have a choice but to sign this contract, or you can't get the service at all.

Comment Re:Rendering time? (Score 1) 17

I'm more interested in how any app would know how long it took an image of that size to render, regardless of whether that differs for white/black pixels (I can see that with, say, transparency options etc. you might be able to make white pixels take longer).

Surely that's a function that you just lob at the renderer and it does it when it feels like it, it doesn't have to be performed in-line (maybe in order, but not in-line).

The fix for the API would appear to be simple... do checks on the bounds, etc. as normal, return success immediately, then blit/render/etc. in the background as necessary. The app won't then have a clue how long a pixel takes to render.
