"Releasing Puppet: Automating Packaging for Many Platforms or 'Make all the things'" by Moses Mendoza, Release Engineer, Puppet Labs. Presentation Overview: A year ago, Puppet Labs had fewer than five fully packaged projects with disparate, difficult packaging workflows that took hours of manual work to accomplish identical results, with varying degrees of success. Since then, we have standardized workflow, added new products, expanded platform support, and removed manual steps (no more hand-crafted builds). This talk/workshop will describe how we have automated entire this process down to a single command from within the source code repo of most of our projects, enabling repeatable, automated packaging, and made packaging available to anyone using our projects’ source on github. This enables us to scale. Once upon a time adding new products to our release process was a major strain on the team. Speaker Bio: Moses Mendoza grew up near Portland, Oregon. Prior to working with Puppet Labs, Moses was primarily a System Administrator, most recently for the Art Institute of Portland as a Mac OSX System Administrator. At Puppet Labs, Moses Mendoza is working to build and scale the automated pipeline and improve continuous delivery at Puppet Labs.

This our Twelfth semiannual report on the global Cryptocurrency mining industry. Bitcoin is the world’s largest special purpose supercomputer. And it is globally decentralized. Millions of nodes all run the same open-source code to secure the Bitcoin network, create value, and put new transactions onto the distributed ledger. The latest Top500 list has just been announced at the ISC 2024 conference in Hamburg, and once again the Frontier supercomputer with 1.2 Exaflops peak performance is number one on the list. If assigned to SHA-256 hashing, Frontier would provide only the equivalent hash rate of about three cabinets of the latest high-end Bitcoin mining systems, costing less than 0.1% of Frontier’s cost. Michael Saylor, Chairman of MicroStrategy, has pointed out that GPUs are two orders of magnitude slower than the 5-nanometer technology of custom ASICs used for Bitcoin mining today. He makes the point that the Bitcoin network is unassailable by all of the hyperscale computing resources combined in AWS, Google, and Microsoft Azure cloud data centers today.

Designing inclusive products is not only a social responsibility but also a business imperative. This talk delves into the journey of creating accessible hardware products that cater to diverse user needs. Key Topics Covered: 1. Introduction to Inclusive Design - Importance of accessibility in product design - Overview of Comcast's commitment to making products accessible to a wide audience 2. Case Study: Xfinity Large Button Voice Remote - Initial challenges and the evolution of the product - User research and feedback that shaped the design - Key features of the final product and their benefits 3. Designing for Diverse Needs - Understanding human-centered design and its historical context - The impact of designing for people with disabilities on overall product quality - Examples from other industries, such as architecture and industrial design 4. Integrating Accessibility from the Beginning - The cost and efficiency benefits of designing for accessibility from the start - The process of embedding accessibility as a core trait rather than an optional feature 5. Real-World Impact and Continuous Improvement - Insights from in-home studies with users having assistive needs - How continuous feedback and iterative design lead to better products - The role of inclusive research and development practices

Syngulon’s technology expands the capacity for selection of microorganisms. The ability to select individual microbes with a behavior of interest is essential, whether for simple cloning at the bench, or for industry-scale production. Synthetic biology uses the concept of “bioengineering” to improve or modify existing genetic systems to create microbes with desired behaviors, and Syngulon uses this approach to develop its selection technologies. This selection technology is based on bacteriocins, ribosomally-produced peptides naturally made by most bacteria to kill competitive microbial species. These bacteriocins can have a limited or wide target range against other microbial species. This technology offers advantageous over antibiotic selection for several reasons: it avoids the use of antibiotics in the first place, helping to reduce the spread of antibiotic resistant microbes. The technology also increases product yield; as bacteriocins are generally smaller peptides, they do not impose a heavy metabolic burden on the producing cell. They can have a wide target specificity, helping to avoid genetic drift. Finally, our system is 100% plasmid-based (e.g. without chromosomal mutations), making it applicable for use in any E. coli strains.

Heather Hedden, Senior Consultant at Enterprise Knowledge, presented “Enterprise Knowledge Graphs: The Importance of Semantics” on May 9, 2024, at the annual Data Summit in Boston. In her presentation, Hedden describes the components of an enterprise knowledge graph and provides further insight into the semantic layer – or knowledge model – component, which includes an ontology and controlled vocabularies, such as taxonomies, for controlled metadata. While data experts tend to focus on the graph database components (RDF triple store or a label property graph), Hedden emphasizes they should not overlook the importance of the semantic layer.
