This dumb password rule is from O2 Spain.

When registering in *Mi O2* app, password length must be exactly 7 or 8 characters (numbers and letters only).
As O2 is part of Telefónica (Movistar), it seems to use the same backend (at least in Spain), so it has the [`same password requirements`](https:
Movistar - Dumb Password Rules
Min 7 and max 8 characters for password! Also to be different than the username: the user name is automatically generated and is based on the surname of the user with some characters replaced by digits :) Has been that way for more than 10 years.

And not only do cars waste space on the road, but also they waste space when parked, taking room from sidewalks, bike lanes etc.

There are simple changes we can make to our cities that will have vast and ongoing positive effects on the lives of community members.

Community leaders with vision are pulling up concrete and replacing it with plant life.

Smart cities know that, as hot as they already are, they’re just going to keep getting hotter. Greening the city not only cools it down, it cleans the air, quiets the noise, improves mental health & happiness, saves public money, & more. Strand Aldwych, London. 2021 vs. 2025. Via @modacitylife.com

Every year, billions of vehicles worldwide shed an estimated 6 million tonnes of tire fragments. These tiny flakes of plastic, generated by normal driving, account for 28% of microplastics entering the environment globally.

Heavy vehicles eg SUVs/EVs especially.

Car tyres shed a quarter of all microplastics in the environment – urgent action is needed
Tiny flakes of plastic, generated by the wear and tear of normal driving, eventually accumulate in the soil, in rivers and lakes, and even in our food.

Se me revuelve el estómago de la rabia. Esta gente, que se dedica sistemáticamente a esparcir mentiras y odio, se monta una fundación contra la censura, para la libertad, para apoyar el periodismo... Con dos cojones. Y gracias a eso, quienes les donen tendrán deducciones fiscales. (sigo)

Javier Cárdenas, junto a Miguel Durán y su sobrino, montan una fundación para, dicen ellos y cito textual: "apoyar el periodismo" y "promover que la ciudadanía tenga acceso a información libre, veraz, plural y exenta de censura". boe.es/boe/dias/202... #BOE

The 2025 Happy City Index is in, and @momentummag.bsky.social is pointing out that many of the world’s happiest cities are also some of the best places to ride a bike. Vancouver is #11, the highest ranked city in North America (cue the usual debates).

This is funny, just a couple of days ago I saw some in my hometown of Oviedo, northern Spain and had to google what there were.

En los últimos 4 años, Madrid ha perdido 78.616 árboles maduros según datos del propio Ayuntamiento. No hablamos de plantones, sino de árboles grandes y verdes que tardaron décadas en crecer y que proporcionaban servicios ecosistémicos irreemplazables. Esto es ecocidio urbano.

Què diferente sería Madrid si se lo pusiéramos fácil a la gente para ir así sin jugarse la vida.

As our cities get hotter and hotter, dark coloured buildings make no rational sense, even if you like that aesthetic (I do).

The same goes for dark coloured roofs.

And dark coloured streets and parking lots with dark coloured asphalt.

That really should be obvious.

Curiosamente la mayoría de la gente cree que su huella de carbono depende de rehusar bolsas, beber en pajitas de papel y poner bombillas LED. Los datos muestran una realidad muy distinta: menos coche y menos carne. Para eso, claro está, hay que darle alternativas a la gente.

Here’s a good question — why is riding a bicycle in the city turning into [actually, being deliberately turned into] a culture war?

Read this @momentummag.bsky.social article.

It doesn’t need to be this way. It’s just smarter transportation that makes urban movement easier for EVERYONE.
Why is Riding a Bicycle in the City Turning Into a Culture War
Here are some key reasons why a safety and efficiency issue is turning into a bicycle culture war.
