Thanks to REST and Swagger, we can build beautiful apis to feed both our browser front-ends and external applications. But, wrapping your Clojure code into resources mostly for your ClojureScript front-end doesn't feel right? Just use RPC? Meet in the middle?
Kekkonen is a small library for managing your (web) apis as commands and queries. No magic, data-driven, un-restful and non-rpc. It's goals are to be small, explicit, extendable and to help enforce your business rules both on the server side and on the ClojureScript frontend. Besides Swagger, it provides run-time context-aware apidocs for Clojure(Script).

Running Airflow Workflows as ETL Processes on Hadoop
While working with Hadoop, you'll eventually encounter the need to schedule and run workflows to perform various operations like ingesting data or performing ETL. There are a number of tools available to assist you with this type of requirement and one such tool that we at Clairvoyant have been looking to use is Apache Airflow. Apache Airflow is an Apache Incubator project that allows you to programmatically create workflows through a python script. This provides a flexible and effective way to design your workflows with little code and setup. In this talk, we will discuss Apache Airflow and how we at Clairvoyant have utilized it for ETL pipelines on Hadoop.

Featherweight Clients (Athens, 2012)
This document outlines a "featherweight stack" for lightweight gCube clients that avoids dependencies on the full gCore stack. It proposes standalone client libraries for discovery, resources, and calling services using just the JDK instead of Axis, Globus, and gCore. Specific topics covered include generating lightweight service stubs, binding resources with JAXB, executing predefined and free-form discovery queries, and providing modular client libraries as an alternative to gCore clients. The goal is to improve client usability, modularity, and independence from obsolete dependencies.

Simplifying Hadoop with RecordService, A Secure and Unified Data Access Path ...
SFHUG presentation from February 2, 2016. One of the key values of the Hadoop ecosystem is its flexibility. There is a myriad of components that make up this ecosystem, allowing Hadoop to tackle otherwise intractable problems. However, having so many components provides a significant integration, implementation, and usability burden. Features that ought to work in all the components often require sizable per-component effort to ensure correctness across the stack.
Lenni Kuff explores RecordService, a new solution to this problem that provides an API to read data from Hadoop storage managers and return them as canonical records. This eliminates the need for components to support individual file formats, handle security, perform auditing, and implement sophisticated IO scheduling and other common processing that is at the bottom of any computation.
Lenni discusses the architecture of the service and the integration work done for MapReduce and Spark. Many existing applications on those frameworks can take advantage of the service with little to no modification. Lenni demonstrates how this provides fine grain (column level and row level) security, through Sentry integration, and improves performance for existing MapReduce and Spark applications by up to 5×. Lenni concludes by discussing how this architecture can enable significant future improvements to the Hadoop ecosystem.
About the speaker: Lenni Kuff is an engineering manager at Cloudera. Before joining Cloudera, he worked at Microsoft on a number of projects including SQL Server storage engine, SQL Azure, and Hadoop on Azure. Lenni graduated from the University of Wisconsin-Madison with degrees in computer science and computer engineering.
Introducing Apache Kafka and why it is important to Oracle, Java and IT profe...
Events are playing an increasingly important role in modern application architecture. They represent fast, streaming data, they fuel the interaction between microservices, they are at the core of CQRS and event sourcing. Apache Kafka has quickly emerged as the de facto standard event platform: open source, cross technology, reliable and extremely scalable and available on any platform, in Docker and from the major cloud platforms- including Oracle Cloud’s Event Hub service. This session explains the what, why and how of Apache Kafka. What role does it play, how is it used and what are challenges and tricks for real life applications. How does it fit in with Oracle Database and Fusion Middleware and with Oracle Public Cloud? In several demos, Kafka is seen at work - in real time streaming event analysis through KSQL, in CQRS and microservices scenarios and with user interfaces updated in real time through events and HTML5 server sent events.
This presentation includes a demonstration of remote database synchronization through Twitter.

Removing Uninteresting Bytes in Software Fuzzing
Imagine a world where software fuzzing, the process of mutating bytes in test seeds to uncover hidden and erroneous program behaviors, becomes faster and more effective. A lot depends on the initial seeds, which can significantly dictate the trajectory of a fuzzing campaign, particularly in terms of how long it takes to uncover interesting behaviour in your code. We introduce DIAR, a technique designed to speedup fuzzing campaigns by pinpointing and eliminating those uninteresting bytes in the seeds. Picture this: instead of wasting valuable resources on meaningless mutations in large, bloated seeds, DIAR removes the unnecessary bytes, streamlining the entire process.
In this work, we equipped AFL, a popular fuzzer, with DIAR and examined two critical Linux libraries -- Libxml's xmllint, a tool for parsing xml documents, and Binutil's readelf, an essential debugging and security analysis command-line tool used to display detailed information about ELF (Executable and Linkable Format). Our preliminary results show that AFL+DIAR does not only discover new paths more quickly but also achieves higher coverage overall. This work thus showcases how starting with lean and optimized seeds can lead to faster, more comprehensive fuzzing campaigns -- and DIAR helps you find such seeds.
