Begin maart was er de eerste samenkomst van TransLab Kampus: individuen, groepen, initiatiefnemers en verenigingen uit de Kempen met interesse voor transitie en deeleconomie die kennis en ervaringen willen uitwisselen. Jef Van Eyck licht in deze presentatie de voorgeschiedenis toe.
De uitdagingen van het lokaal cultuurbeleid in een veranderende samenlevingAvansa Kempen
Socius-medewerkers Gie van den Eeckhaut bracht zijn verhaal op de Kempense Cultuurwerkersdag over het hedendaagse lokaal cultuurbeleid. Hij schetste kort wat democratie inhoudt en vertelde over de verschillende bestuursmodellen doorheen de geschiedenis. Vervolgens ging hij in op de gevolgen daarvan op een lokaal bestuur en hoe je als ambtenaar kan inspelen op hedendaagse ontwikkelingen en veranderingen.
Annick Hollebeke (Velt) praatte in het Groen in de Stadproject voor de Turnhoutse wijken Den Brand en Jef Buyckxstraat over Gifvrij tuinieren, of over de natuurrijke tuin
Het Kempens stilteplatform is voor de deelnemers nog steeds een plek voor ontmoeting en uitwisseling en een bron van inspiratie. Blijvend inzetten op sensibilisatie en stiltebeleving is belangrijk en samenwerkingen stimuleren over sectoren heen is nodig. Tenslotte hield men een pleidooi om op intergemeentelijk niveau verder samen te werken rond ruimtelijke ontwikkeling om zo gebieden die stilte, rust en ruimte kunnen bieden te vrijwaren.

Epistemic Interaction - tuning interfaces to provide information for AI supportAlan Dix
Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024
https://alandix.com/academic/papers/synergy2024-epistemic/
As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.
Elevating Tactical DDD Patterns Through Object CalisthenicsDorra BARTAGUIZ
After immersing yourself in the blue book and its red counterpart, attending DDD-focused conferences, and applying tactical patterns, you're left with a crucial question: How do I ensure my design is effective? Tactical patterns within Domain-Driven Design (DDD) serve as guiding principles for creating clear and manageable domain models. However, achieving success with these patterns requires additional guidance. Interestingly, we've observed that a set of constraints initially designed for training purposes remarkably aligns with effective pattern implementation, offering a more ‘mechanical’ approach. Let's explore together how Object Calisthenics can elevate the design of your tactical DDD patterns, offering concrete help for those venturing into DDD for the first time!

• Before rasterizing a triangle…
– Check z-value of its nearest vertex
against z-value of the smallest
quadtree cell containing the triangle
– If z-test fails, then the entire
triangle is hidden and need not be
rasterized
• Works best when displaying
