Puppetconf 2015 - Puppet Reporting with Elasticsearch Logstash and Kibanapkill

��

Answer deep questions about the health of configuration runs on your nodes with the popular Elasticsearch, Logstash and Kibana stack. While many questions about resources, catalogs and runtimes can be answered by using the Puppet Dashboard or Puppet Enterprise, there are limitations. Putting the reports and run metrics into Elasticsearch gives users full text search and filtering. Also, you can perform metrics and aggregations over resource numbers or run times. Kibana graphs are also a great way to supplement the dashboards available in Puppet Enterprise.

Ensuring Quality in Data Lakes (D&D Meetup Feb 22)lakeFS

��

The document discusses improving data quality in a data lake. It describes three levels (L1-L3) of data lake maturity: L1 involves storing data in an object store in a basic format like CSV files. This provides good performance, cost efficiency, and developer experience. L2 adds optimized table formats like Delta Lake, Hudi and Iceberg that maintain metadata and transaction logs to enable features like schema enforcement, data versioning and isolation. L3 adds data version control systems like lakeFS that extend the object store with Git-like source control operations. This allows instantly reverting bad data, developing data in isolation, and simplifying data reproducibility. LakeFS was demonstrated as an example solution

Understanding When to Adapt a Library: A Case Study on ASF ProjectsAkinori Ihara

��

Software libraries are widely used by both industrial and open source client projects. Ideally, a client user of a library should adopt the latest version that the library project releases. However, sometimes the latest version is not better than a previous version. This is because the latest version may include additional developer effort to test and integrate all changed features. In this study, our main goal is to better understand the relationship between adoption of library versions and its release cycle. Specifically, we conducted an empirical study of release cycles for 23 libraries and how they were adopted by 415 Apache Software Foundation (ASF) client projects. Our findings show that software projects are quicker to update earlier rapid-release libraries compared to library projects with a longer release cycle. Moreover, results suggest that software projects are more likely to adopt the latest version of a rapid-release library compared to libraries with a longer release cycles.

Object garphs swappingMariano Martínez Peck

��

The document discusses object graphs in object-oriented programming and the problem of unused but referenced objects consuming memory. It proposes swapping unused object subgraphs to disk to free up memory while keeping them available. Key challenges include identifying unused object groups, serializing them efficiently with minimal overhead, and handling shared objects and pointers between swapped and unswapped objects. The approach taken is to mark used/unused objects at runtime, group related unused objects into subgraphs, swap only subgraph roots and inner objects to a file while keeping shared objects in memory, and update pointers to swapped objects.

MetacelloMariano Martínez Peck

��

Metacello is a package management system for Monticello that uses configuration files to define project versions and dependencies. A configuration file specifies the Monticello files, dependencies on other projects, and dependencies between packages for a project. Metacello is intended for users, not developers, of a project and allows users to load projects and specify pre and post code execution and project references. The current version is 1.0-beta.27.4 and future plans include improving version naming, validation, and ongoing bug fixes.

Efficient Proxies in SmalltalkMariano Martínez Peck

��

This document discusses proxy objects in Smalltalk. It begins by defining a proxy as a surrogate or placeholder that controls access to another target object. It then describes different approaches to implementing proxies and their limitations, such as issues with traditional approaches that use #doesNotUnderstand:. The document proposes an alternative "ghost model" using #cannotInterpret: to intercept all messages in a uniform way while keeping proxies and handlers separate. It explains how this approach works and advantages it has over traditional proxies. The document also discusses extending this approach to proxy classes and methods.

��

2) Serialize the object graph 3) Create and associate proxies 4) Replace original objects with proxies The document proposes an application-level virtual memory system for object-oriented programs. It works by swapping out unused object graphs to secondary storage and replacing them with proxy objects in primary memory. When a proxy is accessed, its corresponding graph is swapped back in from secondary storage. Key aspects include assigning graph IDs, serializing graphs, creating associated proxy objects, and replacing original objects with proxies during swap out.

Developer Experience is Dead! Long Live Developer Experience! In this keynote-style session, we’ll take a detailed, granular look at the barriers to productivity developers face today and modern approaches for removing them. 10x developers may be a myth, but 10x organizations are very real, as proven by the influential study performed in the 1980s, ‘The Coding War Games.’ Right now, here in early 2025, we seem to be experiencing YAPP (Yet Another Productivity Philosophy), and that philosophy is converging on developer experience. It seems that with every new method, we invent to deliver products, whether physical or virtual, we reinvent productivity philosophies to go alongside them. But which of these approaches works? DORA? SPACE? DevEx? What should we invest in and create urgency behind today so we don’t have the same discussion again in a decade?
