Qem··on Python JIT project was asked to pause development
15% faster on top of a base interpreter that itself got 40%-50% faster on the same timeframe.
Qem··on Python JIT project was asked to pause development
> What a shame it will receive a halt when they where starting to make progress I know that after submitting the pep it will go back to development.

To be fair, the apparent lack of progress of the JIT before was in part due to the same team improving the base interpreter by 40-50% between 3.10 and 3.14. The JIT implementation was pursuing a moving target. It was not some static milestone. Kudos for them.

Qem··on Python JIT project was asked to pause development
> For that reason, the Steering Council is formally requesting a Standards Track PEP be authored that the community can discuss and the Steering Council can formally accept (or reject), making the case for the JIT as a supported, non-experimental part of CPython: its guarantees, its maintenance commitments, and its impact on redistributors.

I didn't notice the current PEP was a provisional one. Hope the new one gets approved. The experimental JIT was reported to finally breaking even and surpassing the default interpreter just a couple of months ago[1].

Qem··on India's surprise baby bust
> Assets and productivity, on the other hand, can grow a lot more than the population.

Source? In a growing market, one can spread their investiments to get safe returns that approach the overall economic growth. In a shrinking market, the same logic should lead to small losses, year over years, making investiment much riskier and unactrative. Markets are made of people.

> The pigeon migrated in enormous flocks, constantly searching for food, shelter, and breeding grounds, and was once the most abundant bird in North America, numbering around 3 billion, and possibly up to 5 billion.

Past performance is not indicative of future results.

Qem··on India's surprise baby bust
> Is it necessary to have a growing population in order to have a growing economy?

Soon we will discover. I suspect the answer will be no, at least not for long. Markets are made of people. Can the economy grow despite a shrinking market losing economies of scale everywhere? I hope, but I don't count on it.

Qem··on India's surprise baby bust
> Total economic stagnation, spiraling population numbers, loss of anything anchored to manual labor, and an aging population.

And this was in a developed country well resourced to take the hit.

> I don't think hardly any super villains exist.

We have billionaries and LLCs, supervillains whose superpowers are based on being rich, don't worrying about the future much beyond the next quarter, and pretending personhood to hold rights like people, but without the possibility of getting arrested.

Qem··on India's surprise baby bust
> Abundant resources (especially housing) and insufficient humans to run a tight bureaucracy will probably lead back to people having babies

If well managed I think this is possible. But it's not given. Another scenario is houses in the countryside, small towns and far suburbs getting empty and soon uninhabitable due to lack of maintenance/infrastructure degradation, and remaining people packing close to core areas that remain high cost.

> because teen pregnancy happens out of wedlock with the fathers usually disappearing

Usually disappeared. Once DNA tests were invented, it became straighforward to go after them. Underrated breakthrough to support children and single mothers.

Qem··on India's surprise baby bust
> Also, women's overall fertility drops off a cliff after 30

Men's too, from 40s up. Not as severe, and not cliff-like in the end like menopause. But it compounds, as the typical couple ages are directly correlated.

Qem··on Meta workers can opt out of being tracked at work up to 30 min
With companies enrolling AI to help look over the shoulder of their employees, I wonder how hard it would be to do some prompt injection just changing what is displayed in the surveiled screen for it to see. Potential for a new vulnerability vector?

Qem··on Memory decline after menopause linked to loss of estrogen production in brain
IIRC in other studies where it's controlled for age, a difference still remains.
Qem··on Memory decline after menopause linked to loss of estrogen production in brain
Just anedoctal evidence, but I have a group of older coworkers, most in late 40s-early 50s, all divorced, and by their reports on their attempts at getting back at dating, success pretty much track how much hair is left. That made me a bit upset, as I'm slowly getting bald myself.
Qem··on Memory decline after menopause linked to loss of estrogen production in brain
Think you. I didn't know there was such overlap in the levels between both genders. Do men's levels also take a hit with age?
Qem··on Memory decline after menopause linked to loss of estrogen production in brain
> Nearly two-thirds of Americans with Alzheimer’s disease (AD) are women, but the reasons why women are more vulnerable are still not fully understood. Scientists have long theorized that the loss of estrogen after menopause may reduce the brain’s natural protection against memory loss and neurodegeneration.

The part that makes no sense for me is men ending with smaller rates of dementia, given they had much less estrogen to begin with. Men have less incidence of dementia. Men also have much lager incidence of baldness. Did somebody already study if baldness and dementia are inversely correlated? I don't know, perhaps sunlight exposure in the scalp have neuroprotective effects?

Given the prevalence of baldness, and the downside of the condition for sexual attractiveness of its bearers, I suspect we will still discover some strong unexpected upside to explain why this trait was selected for regardless.

Qem··on The dead economy theory
> IMO The missing link is that, as long as humans still have political power, that is the basis of their economic power under the new system.

It's because of this Big Tech is busy undermining the basis of democracy, isolating people in bubbles, poisoning political discourse with slop and pimping would be autocrats. They want to strip political power from common citizens, turning toward sefdom.

Qem··on Stress disrupts hippocampal integration of overlapping events, memory inference
I wonder if it helps explain in part why the Publish or Perish culture is wrecking science and stalling scientific progress. The stressful environment it tends to create it's not conductive to learning and thinking in depth.
Qem··on Dehydration's role in learning and memory
I wonder how much of the effects of ageing are due to cascading failures downstream of alterations like these. For example, it's common for people to lose teeth in advanced ages. How much of this is due to dry mouths from insufficient water intake? Fallen teeth then may become entry points for infections, et cetera. Perhaps fixing a few early causes we can avoid a lot of negative effects and live more, without the need to go full spartan in lifestyle discipline.
Qem··on Dehydration's role in learning and memory
Its aggravated because the "water sensor" appears to fail early with age. Elderly people tend to not get the thisty feeling as often, but get dehydrated anyway.
Qem··on Dehydration's role in learning and memory
Most other animals have typical lifespans that don't top two decades.
Qem··on The physicists who convinced Fermilab to send Brazil's emails
> The Brazilian government wanted to control the flow of information across borders, while academia championed unfettered access to international research, both of which were hampered by local telecoms that coveted monetization.

For context, by 1975 Brazil was still aproximately halfway under the brutal military dictatorship that started in 1964, through a military coup supported by Operation Brother Sam[1], and ended only in the late 80s. The movie "The Secret Agent", Oscar nominated in the 2026 ceremony, unfolds in 1977, roughly the same timeframe. It would be a very interesting topic for historical research to comb national files from that period to see if the military surveiled or acted against the named researchers, in some form, for those first attempts to conect to the proto-internet.

Qem··on Actually, democracy dies in H.R.
> HR has a reputation for claiming that they are here to help employees but actually only prioritizing the desires of the corpos

Unions were the institutions that actually helped employees. It's a shame they had their reputations smeared and many were busted, leaving workers out in the cold. The worst run union probably does more for employees than the best HR department.

Qem··on Amazon workers under pressure to up their AI usage are making up tasks
> We didn't. The USSR had 100% employment long ago[0], and all the poverty that goes with it.

I don't think USSR poverty rates surpassed those of Tsarist Russia that preceded them. To their credit, I think ideologic competition between capitalist and communist blocks was part of what allowed improvement of life conditions of workers in capitalist countries, after WWII. Fear of revolutions avoided one-percenters taking all productivity gains in the period. They had to share some to keep guillotines away. As soon as things went south in the USSR, from the 70s onwards, and capitalism took over the whole world, lacking any sort of viable extant competition, we reverted back to the old norm, the workers were denied their share of the productivity gains since then, and here are us now. A regime premised on free competition was undermined by lack of competition to itself.

Qem··on Amazon workers under pressure to up their AI usage are making up tasks
It's a shame AI now has a universal basic jobs[1] program, but humans still not. Companies are paying AI to dig holes, so other AI can fill them.

Qem··on As researchers age, they produce less disruptive work
Academia already underpays highly skilled people. Worsening long-term prospects for people in the area would just make more bright people quit sciences and go right into finance or other bullshit careers that pay more but are near zero-sum or net negative for humanity at large.
