Airbus moving away from AWS:
Airbus has named French cloud services provider Scaleway as the destination for some 900 applications, with an initial 70 getting priority onboarding, as it seeks to put critical systems and data under European control.
Airbus has shown that the cloud service market can work with digital sovereignty, and it did it the old-fashioned way by announcing a tendering process, in itself a market-making event

> “policymakers should also consider new forms of worker empowerment tailored specifically to the rise of AI. One model could be sectoral bargaining over AI use: allowing workers across an industry—not just within a single firm—to collaborate with employers to set standards for how AI is adopted.“

Message from the MIT president on MIT’s funding and talent pipeline:
> … our campus sponsored-research activity is now 10% smaller than it was a year ago.
> Our graduate student enrollment decreased this year…and we expect that to continue next year. […] compared with 2024, our departments’ new enrollments for next year are down close to 20%.

> When eventually I moved out of AWS the hardest thing to undo was the AWS Lambda stuff. The vendor lock-in is real. If you're using AWS Lambda then you have to work to keep convincing yourself this is better than your own web servers. Keep convincing yourself that using AWS Lambda is not a horrible mistake.

Deanonymization with LLMs:

> Corporations could connect seemingly anonymous forum posts to customer profiles for hyper-targeted advertising.
> Attackers could build sophisticated profiles of targets at scale to launch highly personalized social engineering scams.

> Het adviescollege vond de gekozen oplossing veel te ingewikkeld en ook slecht beheersbaar. Gewaarschuwd werd voor kostenoverschrijdingen.

Voor wie interesse heeft in de IT bij de #SVB, zie ook het recente #AcICT advies over sourcing van de infrastructuur. Eén van de adviezen (p.6) luidt:
> Ontwikkel een transparant en herleidbaar afwegingskader voor onderwerpen waarover nog beslissingen genomen moeten worden, zoals gebruik van de public cloud (in relatie tot de gekozen cloudstrategie, de toepasbaarheid en impact op de digitale soevereiniteit van de SVB) en uitfasering van platformen.
