My 3090s just got 1.9x FASTER at BF16 tensor math!!! Same cards, same driver, same 300W, one Linux kernel module.
bf16 tensor pipe: 82 -> 155 TFLOPS
cuBLAS BF16 GEMM 8192: 64 -> 99 TFLOPS
TF32: 41 -> 79 TFLOPS
NVIDIA ships every 3090 with fp32-accumulate tensor math at half speed. The driver even reports it: FMLA32 = 1/2. gpu-unlock by Zagitta sets it to full before the NVIDIA driver loads. After a cold boot all 4 of my cards say FMLA32 = full.
Real inference got less than I predicted. Strata, Qwen3.8 Flash-Next on 2 cards, prefill:
4K: +12%
10K: +12%
90K: 3205 -> 3536 tok/s, +10%
Before installing I said +14 to 19% at 90K, so I was wrong. The GEMM phases got 23% shorter, but they are only about 40% of Strata prefill, and the int8 experts, copies and CUDA core kernels didnt get any faster.
Outputs did not change. With the same expert cache size, my log-prob dump over 1996 teacher-forced positions is the same file byte for byte as the stock run before the module.
Next is Strata itself, now its everything around the GEMMs that makes prefill slow. How I set it up is in the replies.

A landmark Finnish study has found a sharp rise in psychiatric illness among adolescents following sex-alteration procedures.
The peer-reviewed study, published in Acta Paediatrica, tracked every young person under 23 who contacted Finland's gender clinics between 1996 and 2019.
A total 2,083 individuals were studied, with 16,643 matched controls. They were followed for up to 25 years.
Finland's health registers are mandatory, which means no one opts out — this is the complete national picture.
The numbers: psychiatric morbidity rose from 9.8% to 60.7% in adolescents who underwent feminising reassignment, and from 21.6% to 54.5% in masculinising reassignment.
Even after adjusting for prior psychiatric history, gender-referred adolescents faced five times the risk of male population controls, and three times the risk of female controls.
"Psychiatric needs do not subside after medical gender reassignment," the authors concluded.
Referrals after 2010 arrived sicker. 47.9% had already needed psychiatric treatment before their first clinic visit, against 15.3% among controls.
The authors' read: for some adolescents, gender distress may be secondary to other mental health challenges.
The evidence keeps mounting. The silencing continues anyway.
How many more adolescents will be told this is "care"?

Lots of people discuss immigration & crime in Europe, so I compiled what I think is ALL the data on the topic, which is hard because many countries hide it.
Do they commit more crime?
Is it because of age? Sex? Education? Poverty? Culture?
1. Sexual offenses & violent crime:

Me re calienta la mentira! Y la manipulación. Pereira dice q cuando asumió el FA la jubilación mínima era de $8.000 y ahora es de $21.000. Subestima a la gente o pretende tomarnos el pelo. Cuando el FA asume, la jubilación mínima era de $20.057. Hoy es $21.354. Xq tanta maldad?

I remember when I started working at Tesla in 2015 that the possibility of entering the Uruguayan market was a distant dream. Now it’s happening.
Uruguay is the perfect country for E-mobility:
- 100% renewables
- No oil and gas
- No manufacturing of other cars
- Short distances for most people
- Ultra expensive petrol
Happy to see this happening.

I was wondering how to best visualize the exponential growth of LLM capabilities.
@METR_Evals THTC benchmark data might be the clearest representation I’ve seen so far.
THTC (Time Horizon of Tasks Completed) doubles roughly every 4 months.

🇺🇾 Uruguay es el país de Sudamérica con mayor índice de uso de IA, según el informe global de Anthropic.
Índice 1.21 — usamos IA más de lo que nuestro tamaño haría prever. Y no para el ocio: desarrollo web, código, sistemas. Talento y uso real.💡

Se está preparando una nueva modificación a la ley de acceso a la información pública (18.381) con nuevas restricciones. También la ley que obliga la Estado a publicar sus compras, cada vez le obliga menos. El Estado se protege, los políticos y burócratas que nos gobiernan no quieren que podamos controlar en que gastan nuestro dinero y por eso estrechan cada vez más esos instrumentos de información pública. Es un camino poco democrático y menos republicano, donde el ciudadano es cada vez menos informado y más manipulado por el discurso estatal. No debemos permitirlo.
