0 likes•624 views
Erlang is a functional programming language built for concurrency, distribution, and fault tolerance. It uses an immutable data structure and avoids loops with tail recursion. The OTP framework provides tools like supervision trees, behaviors, and hot code swapping. While Erlang syntax looks like Prolog, it can integrate with Ruby via bridges or messaging and runs on Heroku. The document recommends resources for learning Erlang and OTP and participating in the local Erlang meetup.

Taming Pythons with ZooKeeper (Pyconfi edition)
Apache ZooKeeper is a distributed coordination service that allows distributed applications to synchronize data and configuration information and maintain consistency. It provides a hierarchical name space and simple primitives like counters and change notifications. ZooKeeper elects a leader automatically and guarantees consistency by requiring a quorum for all operations. It is useful for applications that need to maintain consistency but also remain available, as it allows choosing consistency and availability over partition tolerance. Spotify uses ZooKeeper to orchestrate distributed tasks across its infrastructure while maintaining a consistent order and remaining available within data centers.
Automating Your Daily Tasks with Scripting - RubyConf 2015 Taiwan
This talk aims to go through basic scripting skills in Ruby. Participants will have a better understanding in managing their daily tasks with scripting. For example, we can setup automated scripts to delete old files on a daily basis instead of doing it manually. These can be done with Bash, Perl and many other scripting languages, but among of which Ruby is better known for its readability. It is easier to write, maintain, and reuse. It saves some time on system management and allows us to put more focus on the projects.

Crafting interactive troubleshooting guides and team documentation for your K...
Crafting interactive troubleshooting guides and team documentation for your K...Manning Publications
This document introduces using Jupyter Notebooks or .NET Interactive Books to create interactive troubleshooting guides and documentation for Kubernetes deployments. Notebooks allow including executable code blocks alongside Markdown text in a way that supports collaboration and version control. They provide benefits over traditional static documentation formats by allowing readers to execute code and see output. Examples are given of using Notebooks to manage local and Azure Kubernetes Service clusters through demonstrations of common Kubernetes tasks like plotting metrics from kubectl. PowerShell is used as the shell language but other options like bash are also supported.Messaging, interoperability and log aggregation - a new framework
In this talk, I will talk about why log files are horrible, logging log lines, and more structured performance metrics from large scale production applications as well as building reliable, scaleable and flexible large scale software systems in multiple languages.
Why (almost) all log formats are horrible will be explained, and why JSON is a good solution for logging will be discussed, along with a number of message queuing, middleware and network transport technologies, including STOMP, AMQP and ZeroMQ.
The Message::Passing framework will be introduced, along with the logstash.net project which the perl code is interoperable with. These are pluggable frameworks in ruby/java/jruby and perl with pre-written sets of inputs, filters and outputs for many many different systems, message formats and transports.
They were initially designed to be aggregators and filters of data for logging. However they are flexible enough to be used as part of your messaging middleware, or even as a replacement for centralised message queuing systems.
You can have your cake and eat it too - an architecture which is flexible, extensible, scaleable and distributed. Build discrete, loosely coupled components which just pass messages to each other easily.
Integrate and interoperate with your existing code and code bases easily, consume from or publish to any existing message queue, logging or performance metrics system you have installed.
Simple examples using common input and output classes will be demonstrated using the framework, as will easily adding your own custom filters. A number of common messaging middleware patterns will be shown to be trivial to implement.
Some higher level use-cases will also be explored, demonstrating log indexing in ElasticSearch and how to build a responsive platform API using webhooks.
Interoperability is also an important goal for messaging middleware. The logstash.net project will be highlighted and we'll discuss crossing the single language barrier, allowing us to have full integration between java, ruby and perl components, and to easily write bindings into libraries we want to reuse in any of those languages.
Radio Free Django
Brum Radio is an independent Internet radio station based in the UK's second city, Birmingham. When I started at the station we had a WordPress website where the schedule had to be manually updated every week from memory, you had to leave the site to listen to shows on-demand and there was no indication of what show you were listening to.
My talk describes building not only a website for a radio station, but scripting a system to record each show and upload it for on-demand listening, without any manual intervention. I discuss how I built a scheduling system to deal with monthly and fortnightly shows (which is harder than it sounds), and dealing with fragile egos, while also presenting my own weekly show on the station.
It's a light talk presented by a very nervous but competent and energetic speaker, which aims to demonstrate how much you can achieve without being the most gifted programmer.

It introduces many popular Perl modules created by Japanese developers, such as WebService::Simple for making web service requests, Riji for creating blogs, and GrowthForecast for visualizing metrics graphs. It encourages attendees to talk to the Japanese developers about their work or any questions. It emphasizes that Japanese developers prioritize speed and simplicity in their modules due to their culture of valuing efficiency.
Day 8 - jRuby
jRuby fixes some issues with the Ruby programming language like memory leaks and lack of kernel level threading by running Ruby code on the Java Virtual Machine which has features like a sophisticated garbage collector, just-in-time compilation for improved performance, and native threading; benchmarks show jRuby provides much higher concurrency and better performance than Ruby for background processing and web applications; deploying a Ruby application using jRuby and a Java application server like Torquebox allows it to take advantage of the reliability, scalability and deployment features of the Java platform.

Day 1 - Intro to Ruby
Barry Jones introduces himself as the instructor for the Ruby on Rails and PostgreSQL course. He has experience developing applications using various languages and databases. He wishes a course like this had been available when he took over a large Perl to Rails conversion project without knowing Rails or PostgreSQL, which led to issues he later had to fix. The goal of the course is to help students gain proficiency with Rails and PostgreSQL faster to avoid similar mistakes.
Day 9 - PostgreSQL Application Architecture
How PostgreSQL affects application architecture decisions from my Ruby on Rails and PostgreSQL - Intro to Advanced class in August 2014.
How to create/improve OSS product and its community (revised)
1) The document discusses how to create and improve open source software (OSS) projects and their communities. It addresses questions around the purpose of the OSS, languages used, versioning, and community engagement.
2) Key recommendations for building community include using English, being open to contributions, demonstrating stability and maintenance, and having a pluggable architecture.
3) The document debates tradeoffs like clean code vs quick contributions, focused vs feature-rich software, and localized vs global development and highlights the need to choose approaches given limitations. Overall it stresses continuous improvement over time.
Introduction to hubot
Hubot is a customizable robot assistant created with Node.js and CoffeeScript. It can interact with chat platforms like Campfire and IRC.

The document demonstrates how to configure Hubot and add scripts to extend its functionality.
Phpmatsuri2010
The document discusses the author's experience with behavior driven development (BDD) tools for PHP. The author:
1) Learned about BDD and Cucumber at a PHP conference and tried to adapt Cucumber for PHP testing but had issues with its structure.
2) Discovered Behat, a BDD framework for PHP inspired by Cucumber. Behat worked well out of the box but did not support Japanese.
3) The author hacked Behat to add Japanese language support by creating a config file and example steps in PHP.
Ruby is dying. What languages are cool now?
- Ruby is no longer considered a "cool" language according to the author, who examines several languages that are currently popular including Swift, Rust, Go, Elixir, Julia, and Dart.
- Swift was created by Apple to replace Objective-C and adds modern features while removing the complexity of C. Rust was created to be safe, concurrent, and practical while combining high and low level capabilities. Go was created at Google to be understandable, productive, and scale well for networking and multiprocessing. Elixir builds on Erlang's concurrency model and adds a Ruby-like syntax. Julia targets scientific computing by combining speed and interactivity. Dart was created by Google to replace JavaScript but never gained

Watch the video of this presentation http://vimeo.com/22144057#at=0
Erlang, the big switch in social games
Online games backend are challenging applications, a single user generates one http call every few seconds, usage volume can spike very quickly and balance between data read and write is close to 50/50 which make the use of write through cache or other common scaling approaches not so effective.
Follow how in our quest for a better architecture to serve millions of games sessions daily and reduce our resource usage we took the decision to write in Erlang our third generation game backend, see how we’re leveraging the actor model in order to change how we use and conceive our persistency layer. See also how introducing Erlang as a new tool in a company is working out, what we found hard from an organizational and technical point of view, which obstacle we hit and how as technical guys we convinced our management to take the risk of bringing in house a different technology.

Rails development environment talk
Reuven Lerner is a web developer and consultant who primarily works with Ruby on Rails and PostgreSQL. He teaches Rails courses and uses various tools like iTerm2, RVM, IRB gems, Emacs, Firefox plugins, Growl, and Pow in his development environment. Emacs is his editor of choice, which he has highly customized over the years using Lisp functions and key bindings.
Zero mq logs
This document discusses using ZeroMQ and Elasticsearch for log aggregation. It proposes using ZeroMQ to transmit structured log data from application servers to a central Logstash server, which would then insert the logs into Elasticsearch for querying and analysis. This approach aims to provide a lightweight logging solution that doesn't block application servers like traditional logging to databases can. The document also provides background on tools like Logstash, Elasticsearch, and Splunk.
Actors and Threads
This document discusses concurrency and parallelism in Ruby. It defines concurrency as performing two operations in tandem, while parallelism refers to performing two operations literally at the same time using multiple cores. The document examines traditional approaches to concurrency like threads and locks in Ruby and their limitations. It advocates for adopting models from other languages like actors and software transactional memory that can provide safer concurrency through message passing and transactions rather than shared mutable state and locks. The document reviews several Ruby libraries that implement actors and proposes areas for further improvement in Ruby's core support for concurrent programming.
Why my Go program is slow?
The document discusses why a Go program may be slow and provides tips for profiling and optimizing Go code performance. It introduces the pprof CPU profiler and how to use it to analyze performance bottlenecks. Some factors that can slow down Go programs include garbage collection, memory copying, and function calls. The document hopes that future versions of Go will include features like concurrent garbage collection to improve speed.
Polyglot Grails
This document discusses using multiple programming languages with Grails, known as polyglot programming. It describes how to use Clojure, Scala, and Ruby with Grails through plugins. For each language, it covers why you would use it with Grails, how to set up the plugin, examples of usage, and limitations. The goal is to push Grails towards being more polyglot and leverage different languages' strengths.

EhTrace -- RoP Hooks
This document describes EhTrace, a tool for tracing the execution of binary programs through hooking and branch stepping. EhTrace uses the Windows VEH exception handler to single step programs by setting flags in the CPU context. It can be used to analyze program control flow at the basic block level for purposes like malware analysis, debugging, and code coverage. The document discusses techniques for maintaining control during tracing and fighting attempts by the target program to detect or alter the tracing.
Finding Needles in Haystacks

Ruby and Distributed Storage Systems
This document discusses using Ruby for distributed storage systems. It describes components like Bigdam, which is Treasure Data's new data ingestion pipeline. Bigdam uses microservices and a distributed key-value store called Bigdam-pool to buffer data. The document discusses designing and testing Bigdam using mocking, interfaces, and integration tests in Ruby. It also explores porting Bigdam-pool from Java to Ruby and investigating Ruby's suitability for tasks like asynchronous I/O, threading, and serialization/deserialization.
Bringing Concurrency to Ruby - RubyConf India 2014
The document discusses bringing concurrency to Ruby. It begins by defining concurrency and parallelism, noting that both are needed but platforms only enable parallelism if jobs can split into concurrent tasks. It reviews concurrency and parallelism in popular Ruby platforms like MRI, JRuby, and Rubinius. The document outlines four rules for concurrency and discusses techniques like immutable data, locking, atomics, and specialized collections for mutable data. It highlights libraries that provide high-level concurrency abstractions like Celluloid for actors and Sidekiq for background jobs.
Scaling with swagger
This document discusses scaling applications and services. It recommends taking a vertical approach by breaking monolithic applications into microservices that communicate through APIs. The Swagger framework is presented as a way to document and test APIs. Swagger can generate client libraries and helps services scale by enabling asynchronous communication through websockets. Taking this vertical, microservices approach with Swagger improves scalability by allowing dedicated teams to own individual services and improves performance through asynchronous communication protocols.

Climate Impact of Software Testing at Nordic Testing Days
My slides at Nordic Testing Days 6.6.2024
Climate impact / sustainability of software testing discussed on the talk. ICT and testing must carry their part of global responsibility to help with the climat warming. We can minimize the carbon footprint but we can also have a carbon handprint, a positive impact on the climate. Quality characteristics can be added with sustainability, and then measured continuously. Test environments can be used less, and in smaller scale and on demand. Test techniques can be used in optimizing or minimizing number of tests. Test automation can be used to speed up testing.

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.
