Nou toch nog maar een keertje in de herhaling, hoe zat het ook alweer met restzetels en voorkeursstemmen: https://berthub.eu/articles/posts/restzetels-en-voorkeursstemmen/
Restzetels en voorkeursstemmen - Bert Hubert's writings
Vanaf een afstandje lijken dingen soms makkelijk. Maar van dichtbij valt het dan vaak tegen, met name als het goed gedaan moet worden. Zoals verkiezingen. Dit proces is allemaal erg ingewikkeld, zo ingewikkeld dat hieronder ongetwijfeld nog fouten staan (mail [email protected]). Ook hou ik het begrijpelijk en gebruik niet exact de woorden uit de kieswet. Ondanks dat ik weleens adviseer bij het bureau van de Kiesraad is dit allemaal gehobby van mij persoonlijk.

Dit is hét onderwerp van de 21e eeuw: digitale zaken. Verslavende algoritmes, de macht van techreuzen, de veiligheid van informatie bij de overheid 👇
Maar weinig aandacht voor digitalisering bij de verkiezingen. ‘Waar blijft de minister van Digitale Zaken?’
Maar weinig aandacht voor digitalisering bij de verkiezingen. ‘Waar blijft de minister van Digitale Zaken?’
Van alle thema’s die deze verkiezingscampagne voorbij komen is de digitalisering misschien wel de opvallendste afwezige. ‘Technologie is geen sexy onderwerp.’

53. Anyone buying a new internal combustion car now is silly. EVs aren’t the answer to everything – especially congestion of cities – but they do use much less energy, it's relatively easy-to-decarbonise energy, and, with flexibility, they can support the grid.

Manifest Big Tech Alternatieven: Wat moet er beter - Bert Hubert's writings
Onze samenleving en overheid draaien inmiddels grotendeels op Amerikaanse big-tech platformen. Velen van ons willen dat dit minder wordt, of zelfs ophoudt. Iedereen in de tech scene hier in Europa is vol van goede wil er wat aan te doen, maar het gaat toch vaak mis. Van nature willen we leuke open en federated en standaardgebaseerde dingen bouwen. Maar dat is niet genoeg, dat is niet waar de wereld (direct) op zit te wachten.

So that $10B bailout for farmers.
Is it a payout for political support? Yeah. Bold move for an industry that talks so much about hard work & independence!
But it's also worse than that. This is a US food crisis in the making.
