The document discusses Erlang and scalability. It introduces common scalability killers like synchronization and resource contention. It describes Erlang's design decisions that promote scalability, including processes with no sharing, no implicit synchronization, and concurrency-oriented programming. The document provides examples of thinking concurrently, rules of thumb for scalability, and case studies showing how Erlang scales on multicore systems.
Having a fast, low-friction Edit/Build/Test cycle is one of the best and easiest ways to increase developer productivity across an organization.
This breadth-first tour covers some of the tools we use at Basho to speed up and streamline the Edit/Build/Test cycle for our Erlang projects.
Erlang - Because s**t Happens by Mahesh Paolini-SubramanyaHakka Labs
Mahesh talks about the buddha-nature of Erlang/OTP, pointing out how the various features of the language tie together into one seamless Fault Tolerant whole. Mahesh emphasizes that Erlang begins and ends with Fault Tolerance. Fault Tolerance is baked into the very genes of Erlang/OTP - something that ends up being amazingly useful when building any kind of system. Mahesh Paolini-Subramanya is the V.P. of R&D at Ubiquiti Networks - a manufacturer of disruptive technology platforms for emerging markets. He has spent the recent past building out Erlang-based massively concurrent Cloud Services and VoIP platforms. Mahesh was previously the CTO of Vocalocity after its merger with Aptela, where he was a founder and CTO.
There is an increasing interest in functional programming from Java developers and the organisations in which they work. For many companies the challenge now is how to make use of the competitive advantage of functional programming. For developers, how do you adapt your mindset to this newly reimagined paradigm? Through the use of examples and a modular approach to design, Clojure made simple will show how developers can be productive quickly without a major change to their current development life-cycle. We will also cover the Clojure build process, tools and exciting projects out there.
VoltDB and Erlang: two very promising beasts, made for the new parallel world, but still lingering in the wings. Not only are they addressing todays challenges but they are using parallel architectures as corner stone of their new and surprising approach to be faster and more productive. What are they good for? Why are we working to team them up?
Erlang promises faster implementation, way better maintenance and 4 times shorter code. VoltDB claims to be two orders of magnitude faster than its competitors. The two share many similarities: both are the result of scientific research and designed from scratch to address the new reality of parallel architectures with full force.
This talk presents the case for Erlang as server language, where it shines, how it looks, and how to get started. It details Erlang's secret sauce: microprocesses, actors, atoms, immutable variables, message passing and pattern matching. (Note: for a longer version of this treatment of Erlang only see: Why Erlang? http://www.slideshare.net/eonblast/why-erlang-gdc-online-2012)
VoltDB's inner workings are explained to understand why it can be so incredibly fast and still better than its NoSQL competitors. The well publicized Node.js benchmark clocking in at 695,000 transactions per second is described and the simple steps to get VoltDB up and running to see the prodigy from up close.
Source examples are presented that show Erlang and VoltDB in action.
The speaker is creator and maintainer of the Erlang VoltDB driver Erlvolt.
Introduction to Erlang for Python ProgrammersPython Ireland
What is Erlang? Why it is important? Why should Python programmers learn Erlang? How is Erlang different? How is Erlang the same? These and other questions will be answered during this talk, as well as this one: Should Erlang be the new programming language you learn this year?
This presentation is aimed at students of the bachelors degree course Applied Computer Science who (almost) finished the course “Advanced Programming Concepts - Functional Programming with Erlang”
This presentation was created for the course “Independent Coursework” at the University of Applied Sciences Berlin.
Supervisor was Professor Dr.-Ing. Hendrik Gärtner
The goal of this talk is to provide new and existing Elixir programmers with knowledge on how to get their application into production and, once it's there, how to tune it for scale.
Clojure is wonderful new language for the JVM that's really making waves: a functional Lisp dialect with full interoperation with Java, and a suite of excellent concurrency utilities ... but it's more than that.
Clojure is a highly expressive and highly adaptable language that allows you to focus on your craft in a way traditional languages such as Java and C# do not. In this session, we'll introduce the language and its core utilities and then introduce the fundamental concepts of functional programming as they apply to Clojure. Clojure has been described as a "high level language beamed back from the near future" ... come see what your future may hold, and why you're really going to like it!
This introduction to Clojure was given to the Utah Java Users Group Aug. 15. It's main focus was on Clojure's time model and how the design of Clojure separates (decomplects) many concepts which are all implemented onto of Objects in Java, and other OO languages. This is the abstract for the original talk:
Tony Hoare famously said "There are two ways of constructing a software design: One way is to make it so simple that there are obviously no deficiencies, and the other way is to make it so complicated that there are no obvious deficiencies. The first method is far more difficult." Clojure is a functional Lisp that targets, among other platforms, the JVM and strives to enable the former approach to building software.
In its pursuit of simplicity Clojure encourages the use of pure functions, sequence abstractions which allow for lazy and parallel processing of data, persistent (immutable) data structures, and a novel way of dealing with state as a succession of values. While these concepts may sound intimidating for those unfamiliar with functional programming, they are actually less complicated than many programming constructs that programmers use everyday.
This talk will cover these concepts and the motivation behind them. You will learn the basics of Clojure programming and will be given a taste of what developing an application in Clojure is like.
Erlang begins and ends with Fault Tolerance.
Fault Tolerance is - formally! - baked into the very genes of Erlang/OTP - something that ends up being amazingly useful when you are building any kind of system. Remember, your clients (and co-workers!) will find new ways to break things, ways that you could never have imagined in your wildest dreams.
This, this is the reason to use Erlang. Once you get it, it completely changes the way you approach development, and you will find yourself writing "erlang" in whatever language you happen to be using (Mind you, writing tail-recursive code in java is a recipe for disaster, but thats another story…)
In this talk, I'll get into this buddha-nature of Erlang/OTP, pointing out how the various features of the language tie together into one seamless Fault Tolerant whole. It'll probably run 45 minutes or so, not counting questions…

GDG Cloud Southlake #33: Boule & Rebala: Effective AppSec in SDLC using Deplo...James Anderson
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).
Speakers:
Bob Boule
Robert Boule is a technology enthusiast with PASSION for technology and making things work along with a knack for helping others understand how things work.

Climate Impact of Software Testing at Nordic Testing DaysKari Kakkonen
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 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.

Observability Concepts EVERY Developer Should Know -- DeveloperWeek Europe.pdfPaige Cruz
Monitoring and observability aren’t traditionally found in software curriculums and many of us cobble this knowledge together from whatever vendor or ecosystem we were first introduced to and whatever is a part of your current company’s observability stack.
While the dev and ops silo continues to crumble….many organizations still relegate monitoring & observability as the purview of ops, infra and SRE teams. This is a mistake - achieving a highly observable system requires collaboration up and down the stack.
I, a former op, would like to extend an invitation to all application developers to join the observability party will share these foundational concepts to build on:
