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 https://www.theregister.com/columnists/2026/07/20/air...

Tiny engine, immense model. - In a 744B mixture-of-experts GLM, only keep the dense part (attention, shared experts, embeddings) in memory, for 10GB. - Swap the 20,000 routed experts in and out by need. > This is not fast. It is a 744B frontier-class model answering correctly on a machine that costs less than one H100 fan. https://github.com/JustVugg/colibri

RE: https://social.overheid.nl/@BZKopensource/116770424383243538 Sweet. Dutch government needed improved accessibility for its https://social.overheid.nl Mastodon instance. It decided to cofinance this, and the features landed in the brand new 4.6 release. “In this way we invest in our own communication tools and those of the full fediverse at once.”

&gt; “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.“ https://bharatramamurti.substack.com/p/empowering-american-workers-in-the

&gt; 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&#39;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. http://fourlightyears.blogspot.com/2026/05/i-returned-to-aws-and-was-reminded-hard.html

&quot;GitLab Act 2&quot; -- GitLab is restructuring. Interesting announcement, including number of &quot;core beliefs&quot;, and a &quot;vision of the world we&#39;re building for&quot; - Software will be built by machines, directed by people. - The agentic era multiplies demand for software. - The consequential work belongs to engineers. https://about.gitlab.com/blog/gitlab-act-2/

Message from the MIT president on MIT’s funding and talent pipeline: &gt; … our campus sponsored-research activity is now 10% smaller than it was a year ago. &gt; Our graduate student enrollment decreased this year…and we expect that to continue next year.

&quot;MCP is Dead; Long Live MCP!&quot; &gt; individual usage of coding agents looks very different from organizational adoption of coding agents where there is an emphasis on visibility, telemetry, security, quality, and being able to operationalize and maintain agent-coded systems by a team of varying degrees of skill and experience. https://chrlschn.dev/blog/2026/03/mcp-is-dead-long-live-mcp/

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: &gt; 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. https://www.adviescollegeicttoetsing.n...

Deanonymization with LLMs: &gt; … the privacy assumptions underlying much of today’s internet no longer hold: &gt; Governments could link pseudonymous accounts to real identities for surveillance of dissidents, journalists, or activists. &gt; Corporations could connect seemingly anonymous forum posts to customer profiles for hyper-targeted advertising. &gt; Attackers could build sophisticated profiles of targets at scale to launch highly personalized social engineering scams...

&gt; Zorg dat je als overheidsorganisatie weet wat je wilt met je IT-systemen, en dat je de daarvoor benodigde kennis in huis hebt. Saar Slegers maakte een mooie Argos-reportage over Citrix en het Openbaar Ministerie, waarin ik vanuit mijn rol bij het AcICT iets mocht vertellen over het belang van voortdurende aandacht voor en investeringen in de eigen IT-systemen. 37 minuten, met diverse sprekers, en ikzelf vanaf 32:30. https://argos.vpro.nl/artikelen/thuiswerksoftware-van-de-overheid-zo...
