Practical tooling for serverless computing

Cloud applications are increasingly built from a mixture of runtime technologies. Hosted functions and service-oriented web hooks are among the most recent ones which are natively supported by cloud platforms. They are collectively referred to as serverless computing by application engineers due to the transparent on-demand instance activation and microbilling without the need to provision infrastructure explicitly. This half-day tutorial explains the use cases for serverless computing and the drivers and existing software solutions behind the programming and deployment model also known as Function-as-a-Service in the overall cloud computing stack. Furthermore, it presents practical open source tools for deriving functions from legacy code and for the management and execution of functions in private and public clouds

Dip coating process: Silicon sheet growth development for the large-area silicon sheet task of the low-cost silicon solar array project

The technical and economic feasibility of producing solar cell quality sheet silicon by dip-coating one surface of carbonized ceramic substrates with a thin layer of large grain polycrystalline silicon was investigated. The dip-coating methods studied were directed toward a minimum cost process with the ultimate objective of producing solar cells with a conversion efficiency of 10% or greater. The technique shows excellent promise for low cost, labor-saving, scale-up potentialities and would provide an end product of sheet silicon with a rigid and strong supportive backing. An experimental dip-coating facility was designed and constructed, several substrates were successfully dip-coated with areas as large as 25 sq cm and thicknesses of 12 micron to 250 micron. There appears to be no serious limitation on the area of a substrate that could be coated. Of the various substrate materials dip-coated, mullite appears to best satisfy the requirement of the program. An inexpensive process was developed for producing mullite in the desired geometry

Prologue in Nieremberg. Aforismsos y Fragmentos Sobre la Naturaleza Humana

Prologue to to bilingual (Spanish - Albanian) edition of aphorisms of the Spanish Jesuit Juan Eusebio Nieremberg (1595-1658)

The Story of the Predestined Pilgrim and His Brother Reprobate. Alexandre de Gusmão. Trans. Christopher C. Lund. Medieval and Renaissance Texts and Studies 489; Medieval and Renaissance Latin America 2. Tempe: Arizona Center for Medieval and Renaissance Studies, 2016. xxxvi + 138 pp. $55.

The Story of the Predestined Pilgrim and His Brother Reprobate, published in Portugal in 1682, is an allegorical novel originally written in Portuguese by Father Alexandre de Gusmão (1629–1724) in the Jesuit mission territory of Brazil. Subsequent editions were printed in both Portuguese and Spanish in Europe and the Americas. Christopher C. Lund’s translation is part of the Latin America series in the Arizona Center for Medieval and Renaissance Studies and is the first English-language edition. It is a welcome addition to scholarly work in the fields of colonial Latin American history and Jesuit history

Seeing in Imagination: Visual Representation and Spiritual Contemplation in the Ascetical Treatises of Juan Eusebio Nieremberg

The once famous Spanish Jesuit Juan Eusebio Nieremberg engages the readers of his ascetical treatises De la diferencia entre lo temporal y eterno (1640) and De la hermosura de Dios (1641) in seeing in their imagination a seemly contradictory set of images of the material world: one in contempt, the other in wonder. However, the images serve the same purpose of fostering a greater appreciation for the eternal. This paper examines how Nieremberg’s visually descriptive narrative relates to the ways in which painters of the Spanish Golden Age –Valdés Leal, Sánchez Cotán and Murillo– display items on their canvases, but also explores its connection to the method of imaginative contemplation, specifically the “composition of place,” in the Spiritual Exercises (1548) of Ignatius Loyola. In doing so, this paper shows how visual representation, both textual and pictorial, related to Jesuit spiritual and pedagogical practices in seventeenth-century Spain

Phage-Like Streptococcus pyogenes Chromosomal Islands (SpyCI) and Mutator Phenotypes: Control by Growth State and Rescue by a SpyCI-Encoded Promoter

We recently showed that a prophage-like Streptococcus pyogenes chromosomal island (SpyCI) controls DNA mismatch repair and other repair functions in M1 genome strain SF370 by dynamic excision and reintegration into the 5′ end of mutL in response to growth, causing the cell to alternate between a wild type and mutator phenotype. Nine of the 16 completed S. pyogenes genomes contain related SpyCI integrated into the identical attachment site in mutL, and in this study we examined a number of these strains to determine whether they also had a mutator phenotype as in SF370. With the exception of M5 genome strain Manfredo, all demonstrated a mutator phenotype as compared to SpyCI-free strain NZ131. The integrase gene (int) in the SpyCIM5 contains a deletion that rendered it inactive, and this deletion predicts that Manfredo would have a pronounced mutator phenotype. Remarkably, this was found not to be the case, but rather a cryptic promoter within the int ORF was identified that ensured constitutive expression of mutL and the downstream genes encoded on the same mRNA, providing a striking example of rescue of gene function following decay of a mobile genetic element. The frequent occurrence of SpyCI in the group A streptococci may facilitate bacterial survival by conferring an inducible mutator phenotype that promotes adaptation in the face of environmental challenges or host immunity

‘Our newsroom in the cloud’: Slack, virtual newsrooms and journalistic practice

Virtual newsrooms have enormous potential: enabling journalists around the world to pool their knowledge, skills and perspectives within joint projects, such as the Panama Papers. These virtual newsrooms are supported by Online Collaborative Software (OCS), the most popular of which is Slack. But although many of the world’s top news organisations now use Slack, there is no empirical research examining its impact on workplace processes or culture. This article presents the results of a year-long ethnographic study of a global digital news outlet, whose remote journalists collaborate, almost exclusively, via Slack. We found that the platform deepened relationships and enabled new creative practices across geographic regions. However, it also contributed to the erasure of the line between private and professional spheres for workers, and introduced new opportunities for management to shape newsroom culture. We argue that the concept of ‘space’ as developed by Harvey can helpfully frame the analysis of these new, important digital platforms

The Ideological Divide: Conflict and the Supreme Court\u27s Certiorari Decision

This Article bridges a gap in existing literature by evaluating, from an empirical perspective, the impact of conflict among the lower courts on the Supreme Court’s decision to grant or deny a petition for a writ of certiorari. Specifically, this Article looks at the political ideology of the lower courts involved in a split of authority on federal law and compares those positions to the political ideology of the Supreme Court itself. This Article concludes that the ideological content of lower court opinions in a conflict case impacts the Supreme Court’s certiorari decisions in a statistically significant way, and thus sheds new light on the role lower court conflict plays in whether the Supreme Court’s exercise of its discretion to grant cert
