Ralfp··on U.S. Study on Puberty Blockers Goes Unpublished Because of Politics, Doctor Says
I've always though people are voting for Trump because there is quite a lot of disillusioned people who consider Trump the anti-establishment choice, whatever the system they are imagining is. Hence "drain the swamp" and "you will be in jail" things. If far left is such an issue, why focus polls keep bringing up economy as top issue for his voters and things like abortion or trans rights come up last? Why conservative candidates who run on mainly anti-trans platforms or anti-abortion platforms lose to conservative candidates that pitch economy as their focus? Why those claims fail to mobilize voters?
Ralfp··on U.S. Study on Puberty Blockers Goes Unpublished Because of Politics, Doctor Says
My problem with this discussion is that when research is published backing the affirming approach to gender dysphoria, it doesnt make it to the media. But when person who published 28 papers about safety and good results of puberty blockers in dysphoric kids withelds one piece because they are worried media will grab it and run with it, exactly this happens.

Ralfp··on Everything you need to know about Python 3.13 – JIT and GIL went up the hill
JIT is in weird place now because according to a recent talk from PyCON US by it’s author, the tier 2 optimizer that prepares code for JIT reduces performance by 20% and JIT just recovers that performance loss.

A lot of langugage is still not optimized by tier 2 [1] and even less has copy and patch templates for JIT. And JIT itself currently has some memory management issues to iron out.

Talk by Brandt Butcher was there but it was made private:

Ralfp··on Everything you need to know about Python 3.13 – JIT and GIL went up the hill
Where it says that? Its simply that Python releases features in yearly cycles and thats what was completed for release.

Idea is to let people experiment with no-GIL to see what it breaks while maintainers and outside contractors improve the performance in future versions.

Ralfp··on Cancer Incidence by Country
We have high environmental pollution in both air and water. Also high rates of alcohol consumption and smoking. And poor food quality.
Ralfp··on Recent Performance Improvements in Function Calls in CPython
They removed most of superinstructions because those prevented other more effective optimizations:

Ralfp··on A list of open source games
Its almost complete. Only multiplayer is missing, but they are now replacing modern renderer with one closer to the original one.

Ralfp··on Meta used monolithic architecture to ship Threads in only five months
I've didn't think "no more PHP". I am just seeing how much non-PHP Meta open sources and talk with Meta guys at events who are building stuff for JS, talking about new client and varied tech stack and then you've told me "actually its still mostly PHP".

Is Haste still in use? Is it in PHP?

FB is not using Python or Node? What’s the build pipeline for their frontend in then? Is GraphQL in PHP? Are AI services in PHP too?
Ralfp··on Meta used monolithic architecture to ship Threads in only five months
A lot of Facebook those days is Node.js, Rust or Python.

Its no longer PHP heavy like it used to be.

Ralfp··on America's affordable house of the future failed
How many of those locations would need development? How economically viable is developing them?
Ralfp··on Where did DNA come from?
This is sometimes called „Andrew Grove Fallacy” after Intel Ceo’s interview in Newsweek where he famously commented how drug research should look at CPU engineering for inspiration to improve itself, missing point that in biology we dont have privilege of knowing how each part of the system works, compared to, eg. designing CPUs, and making invalid analogies.

Dropping from 30% to 15% is meaningless anyway if 99% of growth elsewhere goes to the 1%.
Ralfp··on New cancer drug kinder than chemotherapy
This is not only a morally ambiguous sci-fi, it also skips on issue that we have no 100% proof way to make sure the blood used in the procedures you proposed will not contain cancer cells that will then invade the transplanted organ.

Not to mention issue of patient being weakened by, say, organ failure, to even survive such procedure.

Ralfp··on Htmx Is Composable?
Not every app is so complex that keeping address in sync with the UI requires complex logic. A lot of apps just want to update whats between the navbar and the footer without changing any of those. And URL needs to change from "/" to "/categories/". Sometimes you want to reload part of page as user clicks on tabs or side menu. Or load a content into a modal.

Because people protesting are aware the protest will also be reported and discussed abroad.
Ralfp··on Cloudflare employee posts layoff call with HR and goes viral [video]
The difference is that with union you cant pretend you are just firing few randos because they were terrible at their job and you have to come to the union and say „we need to fire 40 people” and union can say „CloudFlare is doing layoffs” and both investors and people on the job market know its propably not a good time for tge CF, despite the CEO boasting about bazzilions made and best year ever.

TL;DR we are researching metabolism of cancer but findings so far are not even close to validity the claims that Seyfried makes.

Well, PSF is not feeling safe about the conference and are skipping it.

What does this change? 100 years ago people were writing angry letters to the American newspapers about women suffrage being an obvious sign of mental disease spreading in the society. You think people writing those letters were isolated from women and didn't know them?
Ralfp··on An Open Letter to the Python Software Foundation
Political pluralism is nice when you are discussing things like tax levels or investment targets, but a lot of "us vs them" arises from discussions like "I just want to exist in the open without prosecution" vs "your very existence is a problem and needs to be prevented".
Ralfp··on It will never be a good time to buy a house
In 1936 interwar Poland tried to address catastrophic situation with housing market by relaxing zoning law: If you could buy plot of land, you could build a housing there.

Result was few richest poles first race”ing to buy all the land around cities and then build on those plots apartment blocks for rich poles and foreigners to rent units at.

It was post-war communist govt that started building cheap living blocks en masse in ruined cities. Today those neighborhoods have reputation for being some best places to live due to quality of urban planning: a lot of space between blocks and walking distance to services, schools and health care.

Thing with sticker is that usually you go to the toilet and walls are covered in those stickers people removed from their devices as soon as they got away from the bouncers.
Ralfp··on Copycat nutrient leaves pancreatic tumors starving, may inform cancer treatment
Claiming that drinking chia tea will help you shrink pancreatic tumors is quack science.
Ralfp··on Ad-free Facebook, Instagram access planned for $14 per month in Europe
$14 in Poland would be $3.22 VAT extra. 76 PLN according to current exchange rate.

For comparison:

    My mobile plan: 35 PLN
    Disney+: 29 PLN
    Amazon Prime: 11 PLN
    HBO MAX: 30 PLN
    Netflix 4k: 60 PLN
    Apple TV+: 35 PLN
Its even more than Netflix 4k, which here has reputation for costing too much.
