Just having a look around the uLisp site and was impressed to see the detailed performance benchmarks including power www.ulisp.com/show?36M3 - I added time * average power as some boards are really quick, but high power o_O

Love it. PCBs ordered. Displays are hard to find in stock, but ordered. Just firing up Kicad to check some footprints for the rest of the parts 🙏

A cost/benefit framework provides a valuable lens for prioritizing information management efforts and evaluating the potential of information assets. #InfoEconomics #CostBenefitAnalysis #DataStrategy

IT is not just a support function for information management; it's an integral component. Aligning IT strategy with information strategy is critical for success. #ITStrategy #InfoManagement #BusinessAlignment

While security is paramount, overly restrictive information access can hinder productivity and innovation. Finding the right balance is a key challenge for organizations. #InformationAccess #KnowledgeSharing #Productivity

Effective knowledge sharing within an organization is crucial for leveraging collective expertise and reducing key-person risk. IT systems play a vital role in enabling this. #KnowledgeManagement #Collaboration #InfoSharing

Maximizing data value involves enhancing data quality, accessibility, and ease of use. These factors directly impact the return on investment in data initiatives. #DataQuality #DataAccessibility #DataUsability

Reactive "blunder funding" (investing after a mistake) is a suboptimal approach to information management. Proactive, strategic investment yields better long-term results. #InformationInvestment #StrategicPlanning #DataBudget

Felix Barbalet @xlfe.bsky.social · Dec 27

Information exists in two primary forms: data (stored in systems) and knowledge (embodied in people). Each requires distinct management strategies. #DataVsKnowledge #InfoManagement #ITStrategy

Information theory highlights the connection between reduced uncertainty and value creation. Effectively using information leads to better decisions and outcomes. #InformationTheory #DecisionMaking #DataDriven

Information assets present both potential and realized value, alongside inherent risks. A balanced approach considers both value extraction and risk mitigation. #DataRisk #InfoEconomics #StrategicAsset

Information is a strategic asset, not just a byproduct. Effective information management is essential for maximizing its potential value to an organization. #InformationManagement #DataStrategy #BusinessValue
