To vypadá zajímavě!

Helsinki just went a full year without a single traffic death The capital city is Finnish’ed with car-related fatalities.

“Helsinki hasn’t registered a single traffic-related fatality in the past year…Citing data that shows the risk of pedestrian fatality is cut in half by reducing a car’s speed from 40 to 30km/hr, city officials imposed the lower limit in most of Helsinki’s residential areas and city center in 2021.”

Presne tak. Takže Varufakisův technofeudalismus.

Průměrná roční teplota v České republice narostla za posledních 64 let o 2,3 °C. Průměrná teplota jednotlivých měsíců ale roste různě rychle. Nejvíce se oteplují leden, červenec, srpen a prosinec (o více než 2,9 °C od roku 1961), nejméně září a říjen.

A co bude zárukou blahobytu pak?

Border Patrol Left a Refugee at a Cafe. Days Later, He Was Found Dead. The disabled man had been released from jail when federal officers showed up and drove him to a coffee shop. His family searched for him for days.

A visually impaired refugee from Myanmar, who could not speak English, had spent a year at a county jail in Buffalo, when, on a cold winter day, he was picked up by Border Patrol agents and left alone at a coffee shop. His family had searched for him for days, but he was found dead.

its actually very simple

Because you can't use a hammer for that.

Actually…😜…exponential decay continuously slows down!

Also, please, don’t all come to Prague! (pictured)

My effort to reproduce this paper began as part of the Institute for Replication’s ongoing project to systematically examine the reproducibility and robustness of papers in Nature Human Behaviour3; my participation in this endeavour was approved by the Ethical Review Board of Vrije Universiteit Amsterdam’s School of Business and Economics. Inspecting the paper’s first two figures revealed a mathematical impossibility. There are nine EU countries that experienced zero terror attacks during the study’s time frame. However, the paper reports that the inverse hyperbolic sine of these countries’ per capita attack rates are positive, and increase or decrease over time. This is impossible; the inverse hyperbolic sine of zero is zero4. The main outcome variable displayed in the paper’s second figure is hard-coded in the replication data as ‘DVSin’. Figure 1’s top row of plots shows that DVSin is negatively correlated with both terrorist attack rates (r = −0.107, two-sided P = 0.024) and their inverse hyperbolic sine (r = −0.108, two-sided P = 0.022). These plots also show that in the 305/420 country-year observations after 2006 experiencing zero terror attacks (72.6%), DVSin takes on 292 different positive values. This implies that the paper’s main outcome variable cannot possibly be constructed as described in the paper.

"the paper’s main outcome variable cannot possibly be constructed as described in the paper."

Retraction of 2023 paper that did not use the reported variables. The replication report is astonishing www.nature.com/articles/s41...

Amazing!

To je jedna z nejvelkolepějších hlášek vůdce země v lidský historii. Napadá mě jen málo srovnatelných.

Jak si stoupli na ulici a ukázali, že jsou v Kyjevě. V době, kdy nebylo jasný vůbec nic, naopak. Frajeři.

Budeš učit??

also noise pollution in the U.S. is almost entirely from cars and it’s literally giving people heart attacks

I wrote an article about it because it’s so absurd

‚Nemusím pracovat od rána do noci.‘ Docentka z Ukrajiny byla v Česku uklízečka, dnes je psycholožkou „Nemusím pracovat od rána do noci jako v Charkově. Můžu mít volné večery na svoje koníčky. Vydělávám průměrné peníze, ale je to normální život v zemi, kde všechno funguje,“ říká Ukrajinka.

"Olha je docentka psychologie a tak nějak jí bylo pro vytírání škoda. Měla ale kuráž a štěstí a dnes na Karlovarsku vede tým psychoterapeutů." ... No já teda nevím, ale myslím, ž k tomuhle by neměla být potřeba kuráž a štěstí, ale systematická veřejná podpora. www.irozhlas.cz/zpravy-domov...

I'm not entirely sure how they did it, but they've completely cleared the streets around my office in Midtown #NYC.

They paid a lot of people good wages to do the job effectively, thank you for coming to my socialism talk

V nedeli delame v Subzeru konc GRAIL$ a jsme radi. Nova deska je lepsi nez posledni dve, porad tu kapelu velmi respektuju. Budeme radi, kdyz se stavite - dekujeme!

Jj, mám to stejně. Bolení zad mi posilování *zaklepu* v podstatě vyřešilo.

The rain has stopped and a blue sky arcs above the Company as their boats are swept through a narrow gorge. Rearing vast above them on either bank are statues of Isildur and Anárion, carved from the high cliffs: the Argonath, guarding the northern border of old Gondor.

Missing out on what???

Je pro mě fakt těžko pochopitelné, že ještě lidi (i nenáckové!) zůstávají na Twitteru.

In 2022 France implemented a new law stating that 50% of any new public building should be built from timber or other bio materials.

An outcome is new schools that look like this!

Hinkley Point C is now expected to cost EUR 55bn in today's money.

That's a whooping 17,000 €/kW.

Or about 10x the per-kW price of a wind turbine and 30x solar.

Nuclear is a lot of things, but one thing is it not: cheap.

Fascinating!

Když se přidá vítr, tak by to i v zimě mohlo být celkem OK, ne?

Kromě v Česku, kde by to nikdy nefungovalo…/s

Kombinace solárních panelů a baterií je již dostatečně levná, aby většina lidí světa dokázala pokrýt většinu své spotřeby.

Časem se navíc bude celý systém zlevňovat, protože ceny FVE i baterií klesají.
