An exercise started in 2014 going all the way to early 2016 of a simple crawler made in (ugly) Ruby first, then moving to Elixir, to Crystal and back to Ruby and what we can take out of it.
A Journey through new Languages - Intercon 2016Fabio Akita
Minha palestra apresentando minha jornada sobre um código Ruby feito com otimização prematura, passando por Elixir, Crystal e de volta ao Ruby, escrito da forma arquiteturalmente mais "correta" e que no final se tornou até mais performática.
Esta é a minha palestra "Premature Optimization" versão "Code-Only". #THECONFBR
This talks covers some of the basic aspects of the JIP pipeline system (http://pyjip.readthedocs.org) and it's command line interface.
JIP is a system to manage jobs on a Cluster system and simplify the process of building computational pipelines. JIP can interact with Slurm, SGE, PBS/Torque, or LSF clusters and comes with a small local scheduler to run without any remote grid engine.

30 Days to Elixir and Crystal and Back to RubyFabio Akita
Presented at Ruby Dev Summit, a journey through learning Elixir, Crystal and making Ruby better in the process, and why Ruby still can compete in the Web.
This is a slightly updated draft of a talk I was planning on giving at Hadoop Summit in 2015. However the abstract was rejected. Rather than toss it, I'm going to share it with all of you on the (almost) 1 year anniversary of the first big commit of this feature!
Keep in mind that this is (currently) locked away in trunk. If you ever want to see this see the light of day, bug your vendors....
gitfs is a FUSE file system that fully integrates with git. You can mount a remote repository's branch locally, and any subsequent changes made to the files will be automatically committed to the remote.

We'll discuss our experiences with tooling aimed at finding and fixing performance problems in a production Rust application, as experienced through the eyes of somebody who's more familiar with the Go ecosystem but grew to love Rust. We'll cover CPU and Heap profiling, and also briefly touch causal profiling.

The Open Commerce Conference - Premature Optimisation: The Root of All EvilFabio Akita
This is the talk I presented in NYC at the Spree Conference. It's about how we may be making bad decisions out of blindly following misleading pitches. To avoid it, we just need to go back to the basics of CS: Don't optimize prematurely. Here's how.

QCON SP 2016 - Elixir: Tolerância a Falhas para AdultosFabio Akita
Elixir é uma das novas linguagens que está despontando principalmente pela reputação de capacidade de altíssima concorrência e paralelismo que sua VM permite. Mas o principal elemento é que Erlang e por consequência, Elixir, é uma das poucas linguagens criadas assumindo que vamos cometer erros. Ele garante alta disponibilidade nos dando primitivas que permitam que nosso software continue funcionando, mesmo que às vezes ele falhe. E agora vamos ver como Erlang faz isso como Elixir expõe esse potencial a todos nós.
Minha primeira apresentação sobre Elixir, para o evento Dev In Santos. As coisas essenciais que diferenciam Elixir de qualquer outra nova linguagem. Primeira palestra que eu subo com as anotações também (muito vídeo). #FullMetalAlchemist
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.

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:

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. He comes with around 20 years of solution engineering experience in application security, software continuous delivery, and SaaS platforms. He is known for his dynamic presentations in CI/CD and application security integrated in software delivery lifecycle.

Gopinath Rebala is the CTO of OpsMx, where he has overall responsibility for the machine learning and data processing architectures for Secure Software Delivery. Gopi also has a strong connection with our customers, leading design and architecture for strategic implementations. Gopi is a frequent speaker and well-known leader in continuous delivery and integrating security into software delivery.
The Art of the Pitch: WordPress Relationships and SalesLaura Byrne
Clients don’t know what they don’t know. What web solutions are right for them? How does WordPress come into the picture? How do you make sure you understand scope and timeline? What do you do if sometime changes?
All these questions and more will be explored as we talk about matching clients’ needs with what your agency offers without pulling teeth or pulling your hair out. Practical tips, and strategies for successful relationship building that leads to closing the deal.

Elevating Tactical DDD Patterns Through Object CalisthenicsDorra BARTAGUIZ
After immersing yourself in the blue book and its red counterpart, attending DDD-focused conferences, and applying tactical patterns, you're left with a crucial question: How do I ensure my design is effective? Tactical patterns within Domain-Driven Design (DDD) serve as guiding principles for creating clear and manageable domain models. However, achieving success with these patterns requires additional guidance. Interestingly, we've observed that a set of constraints initially designed for training purposes remarkably aligns with effective pattern implementation, offering a more ‘mechanical’ approach. Let's explore together how Object Calisthenics can elevate the design of your tactical DDD patterns, offering concrete help for those venturing into DDD for the first time!
