Automate test-oim
Automate test-oimOim Trust Automated testing involves using automation tools to execute test case suites and compare expected and actual results to generate test reports. The goal is to reduce manually run test cases but not eliminate manual testing. Automation increases test speed and coverage since tests can run unattended. It is suitable for repetitive, tedious, time-consuming, or business critical test cases but not for newly designed or frequently changing tests. The automation process involves tool selection, scope definition, planning, development, execution, and maintenance.

Microservices Architecture: Nirvana or Nightmare
Microservices Architecture: Nirvana or NightmareChristophe Marchal Microservice oriented architecture is very fashion. It is very easy to find posts describing success story with this kind of architecture. However, this kind of architecture comes with a set of traps and assume a lot of things about your company's IT.
In this task I will show in which context this kind of architecture makes sense, the challenges coming with it, the kind of data architecture it implies and the most mature existing stacks to work with.

Capistrano
CapistranoChristophe Marchal Lightning talk about an old tool for deploy automation: Capistrano. Automation tools are fashion nowadays, however Capistrano is part of those old and mature tools that are very good in certain contexts. If you have to upload your code source to remote server in order to deploy your application, Capistrano can be a good fit. It is also easy to extends to support complex workflows.
Aws, play! couch db scaling soa in the cloud
Aws, play! couch db scaling soa in the cloudChristophe Marchal 1) The document discusses using a microservices architecture (SOA) for a 6 month MVP project in Brazil for taxation.
2) It advocates using lightweight frameworks like Play and CouchDB to allow for minimum viable architecture and design while still achieving decoupling and flexibility.
3) The services defined are NFe, Report, Company, and User with CouchDB used for document storage to allow for versioning of documents and designs for ease of upgrades and deployments.
Devops e a nova cultura - TDC Florianopolis 2015
Devops e a nova cultura - TDC Florianopolis 2015Christophe Marchal This document discusses DevOps concepts including:
1. DevOps is a journey to improve collaboration between development and operations teams, not a process or methodology. It focuses on a continuous transformation through experiences shared.
2. Early DevOps practices include continuous integration to reduce bugs, deploying features faster through automation, and improving quality.
3. As applications grow, teams face challenges like long merge times and deploy delays. Adopting microservices architecture and infrastructure as code helps teams deploy individual services independently and quickly.
4. Organizing teams around business capabilities and services using a Lean Startup approach allows independent deployments and faster feedback. Monitoring everything is also important for DevOps.
CUDA
CUDAChristophe Marchal The document discusses Compute Unified Device Architecture (CUDA) and how graphics processing units (GPUs) can be used for general-purpose parallel computing. It notes that CPUs have limitations for parallel processing while GPUs are well-suited for parallel workloads due to their high number of threads. The document provides an example of a basic "Hello World" GPU program to illustrate GPU programming and architecture concepts like grids, blocks, and threads. It also mentions several programming languages and libraries that can be used to develop CUDA applications.
Monads in practice

Hbase
HbaseChristophe Marchal HBase is a distributed, scalable, big data store that provides fast random access and strong consistency for large amounts of sparse data across servers. It is built on top of HDFS for storage and uses a big table made up of many regions that are automatically sharded and replicated for failure tolerance. While it can handle large volumes of data across datacenters, it requires a minimum of 5 nodes and does not support indexing or sorting beyond row keys.
Integration with hdfs using WebDFS and NFS
Integration with hdfs using WebDFS and NFSChristophe Marchal This document discusses two methods for integrating HDFS with other systems: NFS and WebHDFS. NFS allows browsing, downloading, and uploading files in HDFS by mounting HDFS as an NFS share. WebHDFS provides a REST API for HDFS operations over HTTP such as file metadata retrieval, reading/writing files, and file appends. The document provides examples of mounting HDFS using NFS and making HTTP requests to the WebHDFS API.
Big data: Loading your data with flume and sqoop
Big data: Loading your data with flume and sqoopChristophe Marchal This document discusses loading data into Hadoop 2 using SQOOP and Flume. It covers batch loading versus stream loading with SQOOP, describing SQOOP imports and exports. Flume is described as a distributed, reliable, and available system for collecting and aggregating data from various sources and writing to sinks like HDFS. Examples are provided for using both SQOOP and Flume to import data into HDFS and Hive.

Crazy Incentives and How They Kill Security. How Do You Turn the Wheel?
Crazy Incentives and How They Kill Security. How Do You Turn the Wheel?Christian Folini Everybody is driven by incentives. Good incentives persuade us to do the right thing and patch our servers. Bad incentives make us eat unhealthy food and follow stupid security practices.
There is a huge resource problem in IT, especially in the IT security industry. Therefore, you would expect people to pay attention to the existing incentives and the ones they create with their budget allocation, their awareness training, their security reports, etc.
But reality paints a different picture: Bad incentives all around! We see insane security practices eating valuable time and online training annoying corporate users.
But it's even worse. I've come across incentives that lure companies into creating bad products, and I've seen companies create products that incentivize their customers to waste their time.
It takes people like you and me to say "NO" and stand up for real security!

GDG Cloud Southlake #42: Suresh Mathew: Autonomous Resource Optimization: How...James Anderson Autonomous Resource Optimization: How AI is Solving the Overprovisioning Problem
In this session, Suresh Mathew will explore how autonomous AI is revolutionizing cloud resource management for DevOps, SRE, and Platform Engineering teams.
Traditional cloud infrastructure typically suffers from significant overprovisioning—a "better safe than sorry" approach that leads to wasted resources and inflated costs. This presentation will demonstrate how AI-powered autonomous systems are eliminating this problem through continuous, real-time optimization.
Key topics include:
Why manual and rule-based optimization approaches fall short in dynamic cloud environments
How machine learning predicts workload patterns to right-size resources before they're needed
Real-world implementation strategies that don't compromise reliability or performance
Featured case study: Learn how Palo Alto Networks implemented autonomous resource optimization to save $3.5M in cloud costs while maintaining strict performance SLAs across their global security infrastructure.
Bio:
Suresh Mathew is the CEO and Founder of Sedai, an autonomous cloud management platform. Previously, as Sr. MTS Architect at PayPal, he built an AI/ML platform that autonomously resolved performance and availability issues—executing over 2 million remediations annually and becoming the only system trusted to operate independently during peak holiday traffic.

Slack like a pro: strategies for 10x engineering teams
Slack like a pro: strategies for 10x engineering teamsNacho Cougil You know Slack, right? It's that tool that some of us have known for the amount of "noise" it generates per second (and that many of us mute as soon as we install it 😅).
But, do you really know it? Do you know how to use it to get the most out of it? Are you sure 🤔? Are you tired of the amount of messages you have to reply to? Are you worried about the hundred conversations you have open? Or are you unaware of changes in projects relevant to your team? Would you like to automate tasks but don't know how to do so?
In this session, I'll try to share how using Slack can help you to be more productive, not only for you but for your colleagues and how that can help you to be much more efficient... and live more relaxed 😉.
If you thought that our work was based (only) on writing code, ... I'm sorry to tell you, but the truth is that it's not 😅. What's more, in the fast-paced world we live in, where so many things change at an accelerated speed, communication is key, and if you use Slack, you should learn to make the most of it.

Dark Dynamism: drones, dark factories and deurbanization
Dark Dynamism: drones, dark factories and deurbanizationJakub Šimek Startup villages are the next frontier on the road to network states. This book aims to serve as a practical guide to bootstrap a desired future that is both definite and optimistic, to quote Peter Thiel’s framework.
Dark Dynamism is my second book, a kind of sequel to Bespoke Balajisms I published on Kindle in 2024. The first book was about 90 ideas of Balaji Srinivasan and 10 of my own concepts, I built on top of his thinking.
In Dark Dynamism, I focus on my ideas I played with over the last 8 years, inspired by Balaji Srinivasan, Alexander Bard and many people from the Game B and IDW scenes.
