In the upper left corner is the Volt logo. 
There are two photo’s: each covers half the slide. 
Top half: London. 
In the background is the government building in London. A huge crowd of protestors is in the foreground. They have British flags, and flags of England, Scotland, Wales. People climbed on top of a statue of a lion.
Bottom half: The Hague.
Orange smoke. Protestors, mostly men. Many dressed in black with face covering. They carry normal Dutch flags and so-called ‘prince flags’ or ‘NSB and VOC flags’. These flags represented the Nazi’s in World War 2, and they represent the neo-Nazi’s today.

In the middle of the slide is a black text box with the text: Political violence in European cities fits the authoritarian playbook 100%. Icon arrow to the next slide.

In the background of this purple slide is a vague picture of a burning police car and behind it we see protestors. 
Black text box holds the title: The authoritarian playbook
Text below:
Facts don’t matter, lie shamelessly
Idealise a past that doesn’t exist
Scapegoat foreigners, minorities, queer
Attack anyone who would counter lies: press, science, art, education
Say political opponents are destroying the country
Label all of them as enemies and call for emergency measures.
Say the white majority is the victim of a conspiracy to replace them
Stoke violence
Seek allies in other Great Leaders

In the background of this purple slide is a vague picture of two old ladies and a sign: grannies against fascism.
Black text box with the title: What can you do?
Text below:
Vote
Speak up
Unite
Socialise
Recognise what's happening
Support democracy
Do not obey in advance
Know that you are with many
Every little contribution counts

The far-right is a political technology for getting votes and then usurping power. We know its mechanics, so let's focus on the antidote. Join Volt https://volt.team/simple-join/en

Testo viola con titolo “Javier Milei è nei pasticci e Trump gli tende una mano”. Frase critica sul “macellaio sociale turbo-liberista e autoritario”. In basso, Milei ride mostrando un foglio, Trump siede accanto con le mani aperte. Logo Volt in alto.

Sfondo viola con titolo “La situazione”. Testo descrive la crisi argentina: inflazione, prezzi in aumento, salari insufficienti, servizi pubblici smantellati da Milei in nome del mercato libero. Parole chiave evidenziate in giallo. Logo Volt in alto.

Sfondo viola, testo spiega l’intervento di Donald Trump che promette 20 miliardi di dollari per aiutare l’Argentina. Descrive obiettivi USA: ridurre influenza cinese, imporre austerità, rafforzare modello economico diseguale. Critica alla “libertà” di Milei basata su debiti. Logo Volt.

Sfondo viola, testo collega il modello di Milei ai populismi europei. Si citano Meloni, Orbán e Le Pen come leader che guardano al liberismo selvaggio argentino e alla propaganda polarizzante. Chiusura con “Volt rifiuta questa deriva”. Parole chiave evidenziate in giallo.

In #Argentina la crisi esplode: inflazione, tagli a sanità e scuola. #Milei, paladino della “#libertà”, ora dipende da #Trump e dai suoi miliardi. Questo è il liberismo che genera solo precarietà. #Volt propone un’ #Europa giusta, sociale e indipendente, costruita per le persone. 💜

Whoa: The European Space Agency's Solar Orbiter spacecraft got a spectacular view of Comet ATLAS (C/2024 G3) as it passed close to the Sun. Look at that enormous, splintered tail!

This comet won't be seen again for another 600,000 years. 🧪🔭

Hello, Venus!

Heading toward #Venus for a flyby, our #SolarOrbiter mission caught the planet on camera using the SoloHI instrument of the US Naval Research Laboratory.

SoloHI was designed to capture the faint light of the solar wind. The much brighter Venus “smears” starlight around the edges.

Remember our call to attract talent? The Commission took a first step in the right direction! 🧲
 
Let’s move forward with a Make it in Europe campaign & Express Visa for top talent. A possible game-changer for companies, as it would cut bureaucratic red tape & allow to hire skilled talent quickly.

Ariane 6 soared to the skies once again! 🚀

This time, with a triple boost from Vinci!

After the deployment of its passenger, Ariane 6's Vinci engine’s third boost put the upper stage into a reentry orbit to safely burn up through Earth’s atmosphere, preventing accumulation of space debris.

NIST proposes barring some of the most nonsensical password rules Proposed guidelines aim to inject badly needed common sense into password hygiene.

Thanks NIST, it was about time!

Verifiers and CSPs SHALL NOT impose other composition rules (e.g., requiring mixtures of different character types) for passwords.Verifiers and CSPs SHALL NOT require users to change passwords periodically
