Here's an example of how to code with Riak using cURL and ruby to do a basic PUT, GET and more. We then index the data using Apache Solr integration.
No matter what platform we’re discussing, we’re beyond the view of rows and columns. Data is more diverse than ever. More difficult to parse. Here is some of that story.
Riak (http://basho.com), a dynamo-inspired, open-source key/value datastore, was built to scale from a single machine to a 100+ cluster without driving you or your operations team crazy.
This presentation points out the characteristics of Riak that become important in small, medium, and large clusters, and then demonstrates the Riak API via the Python client library.
Apache Spark for Library Developers with Erik Erlandson and William BentonDatabricks
As a developer, data engineer, or data scientist, you’ve seen how Apache Spark is expressive enough to let you solve problems elegantly and efficient enough to let you scale out to handle more data. However, if you’re solving the same problems again and again, you probably want to capture and distribute your solutions so that you can focus on new problems and so other people can reuse and remix them: you want to develop a library that extends Spark.
You faced a learning curve when you first started using Spark, and you’ll face a different learning curve as you start to develop reusable abstractions atop Spark. In this talk, two experienced Spark library developers will give you the background and context you’ll need to turn your code into a library that you can share with the world. We’ll cover: Issues to consider when developing parallel algorithms with Spark, Designing generic, robust functions that operate on data frames and datasets, Extending data frames with user-defined functions (UDFs) and user-defined aggregates (UDAFs), Best practices around caching and broadcasting, and why these are especially important for library developers, Integrating with ML pipelines, Exposing key functionality in both Python and Scala, and How to test, build, and publish your library for the community.
We’ll back up our advice with concrete examples from real packages built atop Spark. You’ll leave this talk informed and inspired to take your Spark proficiency to the next level and develop and publish an awesome library of your own.
Ruby on Rails is a powerful web framework that focuses on developer productivity. Riak is a friendly key-value store that is simple, flexible and scalable. Put them together and you have lots of exciting possibilities!

Overview of The Scala Based Lift Web FrameworkIndicThreads
All of us having experience with other web frameworks such as Struts,Tapestry, Rails, etc would ask “Why another framework? Does Lift really solve problems any differently or more effectively than the ones we’ve used before? The Lift Web Framework provides an advanced set of tools for quickly and easily building real-time, multi-users, interactive web applications. Lift has a unique advantage that no other web framework currently shares: the Scala programming language. Scala is a relatively new language developed by Martin Odersky and his group at EPFL Switzerland. Scala is a hybrid Object Oriented and Functional language that runs at native speeds on the JVM and fully interoperates with Java code. Lift is a hybrid web framework built on Scala. Lift derives its features and idioms from the best of existing web frameworks as well as the functional and OO features in Scala. It compiles to Java bytecode and runs on the JVM, which means that we can leverage the vast ecosystem of Java libraries just as we would with any other java web framework. This presentation details the advantages of this Scala based Web framework over all the existing frameworks that we have used uptil now and shows a small sample application built with Lift. We will create a basic application with a model that maps to RDBMS, web pages that correspond to back end logic and bind dynamically created content to elements on the webpage.

node.js and native code extensions by examplePhilipp Fehre
Over the last years node.js has evolved to be a great language to build web applications. The reason for this is not only that it is based on JavaScript which already is established around "the web" but also that it provides excellent facilities for extensions, not only via JavaScript but also integration of native C libraries. Couchbase makes a lot of use of this fact making the Couchbase node.js SDK (Couchnode) a wrapper around the C library providing a node.js like API, but leveraging the power of a native C library underneat. So how is this done? How does such a package look like? Let me show you how integration of C in node.js works and how to "read" a package like Couchnode.
JRuby is a great way to use native Java libraries and get around the project overhead of Java, but how do you actually use Java from JRuby? This talk explores building a JRuby application, backed by the portable Java version of Couchbase Mobile.
While JRuby is build to interface with Java, when calling out to JVM land there are all those little hurdles to overcome. Handling Strings correctly, using native Collection types, and interfacing with libraries which expect those native types instead of the ones provided by JRuby, and last but not least Implementing native interfaces to pass around.
Oh and by the way all of this runs on a little Raspberry Pi!
This presentation was given by David Maier @magicable @munichnosql may 2014. The code can be found https://github.com/dmaier-couchbase/cbl-android-tasklist
Before joining Couchbase Phil has been a consultant on many different node.js and NoSQL projects working with many different languages and databases. By helping clients solve problems regarding scalability as well building completely new APIs he gained a broad knowledge of the available platforms and their tradeoffs in the big and small. He's a Developer Evangelist for Couchbase where he works to educate developers on the different parts of using a NoSQL database from mobile to big iron servers.

PHP Frameworks: I want to break free (IPC Berlin 2024)Ralf Eggert
In this presentation, we examine the challenges and limitations of relying too heavily on PHP frameworks in web development. We discuss the history of PHP and its frameworks to understand how this dependence has evolved. The focus will be on providing concrete tips and strategies to reduce reliance on these frameworks, based on real-world examples and practical considerations. The goal is to equip developers with the skills and knowledge to create more flexible and future-proof web applications. We'll explore the importance of maintaining autonomy in a rapidly changing tech landscape and how to make informed decisions in PHP development.
This talk is aimed at encouraging a more independent approach to using PHP frameworks, moving towards a more flexible and future-proof approach to PHP development.
Removing Uninteresting Bytes in Software FuzzingAftab Hussain
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.

zkStudyClub - Reef: Fast Succinct Non-Interactive Zero-Knowledge Regex ProofsAlex Pruden
This paper presents Reef, a system for generating publicly verifiable succinct non-interactive zero-knowledge proofs that a committed document matches or does not match a regular expression. We describe applications such as proving the strength of passwords, the provenance of email despite redactions, the validity of oblivious DNS queries, and the existence of mutations in DNA. Reef supports the Perl Compatible Regular Expression syntax, including wildcards, alternation, ranges, capture groups, Kleene star, negations, and lookarounds. Reef introduces a new type of automata, Skipping Alternating Finite Automata (SAFA), that skips irrelevant parts of a document when producing proofs without undermining soundness, and instantiates SAFA with a lookup argument. Our experimental evaluation confirms that Reef can generate proofs for documents with 32M characters; the proofs are small and cheap to verify (under a second).

Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).
