US fertility rate fell to a record low in 2024, mirroring a global trend

techspot.com Rob Thubron 2025-12-23 17:19:00

In a nutshell: The CDC released data this month that shows the US fertility rate fell to an all-time low in 2024, but the number of babies that were born last year increased YoY. It means that while there were more births overall, a smaller percentage of women of childbearing age are having children. There were 3.6 million babies born in the US in 2024, up 1% compared to the previous year, according to the CDC's data. But the general fertility rate – the number of live births per 1,000 women of

Structural-Demographic Theory

news.ycombinator.com Unknown 2025-12-26 10:04:03

The causes of revolutions and major rebellions are in many ways similar to processes that cause earthquakes (Goldstone 1991: 35). In both revolutions and earthquakes it is useful to distinguish the structural conditions (pressures, which build up slowly) from triggers (sudden releasing events, which immediately precede a social or geological eruption). Specific triggers of political upheavals, such as self-immolation of a fruit vendor, which triggered the Arabic Spring in Tunisia, are very hard

I wasted weeks hand optimizing assembly because I benchmarked on random data

Once upon a time I worked in the field of Java Optimizations. The target system was a distributed data processing platform that ran across hundreds of thousands of machines. At such scales, a 0.5% improvement would easily make up my salary going forward, and 2% was a good result for the half. That doesn’t mean it was easy. Never have I ever seen such a highly optimized Java codebase. Not before, not since. Every low hanging fruit had long since been picked clean. For example, there was minima

If you’re running the developer beta on your iPhone and get a lot of spam or robocalls, you might have noticed that the Silence Unknown Callers feature had gone missing, at least for some users. With today’s beta release, it’s back, now integrated as part of the new Call Screening feature. Call Screening is one of the most useful features coming in iOS 26.

How to Spot and Guard Against Wrong Number Scams

wired.com David Nield 2026-01-09 04:00:00

Something you can be sure of when it comes to scams and swindles is that the methods used to try to part you from your data, your money, or both are constantly changing—which of course makes it more difficult to spot scenarios where someone is attempting to trick you. One simple scam that's continuing to get more common starts off with text from someone who has apparently messaged the wrong number. There's no mistake though: Your number is being deliberately targeted by a fraudster. A wrong nu

Log by Time, not by Count July 20, 2025 "How to Log" is a surprisingly deep topic in software engineering with many different viewpoints, and they're almost all valid in different situations. I'm going to argue that when processing lots of events, it's best to log every X seconds, rather than every X messages. This is a simple concept, but I've never seen it written down before.

Phrase origin: Why do we "call" functions?

On StackExchange, someone asks why programmers talk about “calling” a function. Several possible allusions spring to mind: Calling a function is like calling on a friend — we go, we stay a while, we come back. Calling a function is like calling for a servant — a summoning to perform a task. Calling a function is like making a phone call — we ask a question and get an answer from outside ourselves.
