Git Sensitive Data
Git can unintentionally store sensitive data like passwords or keys in its commit history. While commands like filter-branch can remove sensitive data from the local history, it may still be retrievable from remote repositories unless the history is rewritten there as well. The safest approach is to change all credentials and remove the local git repository entirely.
Productivity Tips for Programmers
The flow is what makes a programmer thrive or fail. How many interruptions did you have today? Can you stop them?
Interruptions turn each day into chunks of productivity. Each interruption costs a programmer at least 10 minutes, plus the time spent during the interruption.
Here are some tips to avoid interruptions and get to a flow state of mind. Kill interruptions before they kill your productivity.
When was the last time that you programmed without any interruptions?
Some of the tips:
1. Keep your email clients closed
2. Keep Twitter closed
3. Keep Facebook closed
4. Start tracking time spent on every project
5. Unplug your phone
6. Silence your cell phone
7. Use Slack
Manage your interruptions before they manage your productivity.
Peer Review Guidelines
A few guidelines for peer reviews at Ombu Labs. Be nice, be constructive, suggest alternatives, start discussions, use Git branches, Github pull requests and keep it lean.
Make sure that the pull requests solve a concrete problem today. You can always refactor your solution later. Do not design for the future.
Keep it simple stupid and learn from the comments in your pull requests.

How does electricity affects our life1
Electricity affects our lives through electric circuits, which require a closed loop path containing a power source, load, and connectors for electric current to flow. A basic electric circuit consists of a battery, wires, a light bulb, and may include a switch to turn the current on and off, allowing electricity to power devices and light bulbs. For current to flow, a circuit must be closed and continuous without any gaps, whereas an open circuit will not allow current to pass through due to breaks in the loop.

RFID and its application
This document discusses RFID and its applications. It provides an introduction to RFID, describing its components and types of tags. It then discusses several current applications of RFID, including in access control, asset tracking, authentication, and supply chain management. The document also presents the results of an online survey that found library management and logistics/supply chain management to be areas seen as suitable for RFID application. It concludes that RFID provides benefits like contactless reading and storing more data than barcodes but that costs remain relatively high and standards are still being developed.

Lecture Atmospheric Temperature
Temperature is a measure of the average kinetic energy of particles in a substance. It is expressed on comparative scales like Celsius, Fahrenheit and Kelvin. Thermometers use materials like mercury that expand with increasing heat to measure temperature. Temperature inversions occur when warm air is above cooler air near the surface, trapping pollutants. Inversions impact air quality by preventing the dispersion of pollution. Clouds also impact temperature by reflecting sunlight to lower maximum temperatures while trapping heat at night to raise minimums.

Masculinity and Misogyny in the Digital Age
Ditch the Label – one of the largest anti-bullying charities in the world – worked with Brandwatch to analyze 19 million public tweets over a four year period to explore the current climate of misogyny and constructs of masculinity as expressed across social media.
The project sheds light on discriminatory language, but should not be viewed as an argument for online censorship. Rather, the data points to the need for a nuanced approach, further open debate and awareness, and positive role models.

A short guide to git's interactive rebase
Git's interactive rebase allows developers to clean up and edit commits before publishing them. It can be used to squash multiple commits into one, reorder commits, or drop unwanted commits and move them to a new branch to keep feature and bugfix branches more logically separated. The interactive rebase is started with `git rebase -i` which opens an editor showing the commits to allow picking, editing, squashing or dropping them.
CSS3 Animations
CSS3 allows HTML elements to be animated without JavaScript or Flash. Keyframes are used to define the stages and styles of an animation over its duration. CSS properties like animation-name, animation-duration, and animation-timing-function can be used to control animations, and animations can be defined using a shorthand animation property. Browser support for CSS animations varies.
Gotchas and Stack Traces in Ruby
This document discusses common "gotchas" and issues when working with Ruby, along with explanations of stack traces. It covers:
1. Syntax errors due to whitespace when calling methods.
2. The behavior of the "any?" method on arrays and how it checks for "truthy" elements.
3. That constants in Ruby can be reassigned with a warning, and examples of variable scope errors.
4. Examples of stack traces for different errors and the importance of including the full trace when asking for help to identify the root cause.

Mocks vs. Stubs
This talked is inspired by Martin Fowler's "Mocks aren't stubs" http://martinfowler.com/articles/mocksArentStubs.html
We talked about Cassical TDD vs. Mockist TDD and the libraries that help Ruby developers with their tests.
Webmock, FactoryGirl, VCR, Rspec mocks, stubs and spies.
What do you prefer? To mock everything, or to mock as less as possible?
Intro to Active Record
ActiveRecord is an object-relational mapping (ORM) pattern that allows developers to interact with a database using objects. It establishes a one-to-one relationship between classes and database tables, with each class representing a database table and objects representing table rows. ActiveRecord provides methods for easily creating, reading, updating, and deleting records in the database. It also handles associations between models and allows chaining conditions to build queries before executing them against the database.
Relational Databases 101
A brief introduction to relational databases, SQL and ActiveRecord.
What's a SELECT, UPDATE, INSERT or DELETE query? What's an Index, a Foreign Key, a Primary Key?
The 7 Days Open Source Challenge
The document outlines a 7 day challenge to contribute to open source projects in order to gain experience, respect, good karma, and knowledge. It encourages participants to submit new issues, try to solve existing issues, add relevant information to issues, improve documentation, write failing test cases, and submit pull requests for 7 straight days. If a day is skipped, one must start over. Upon completion, participants should share their experience and look to codetriage.com or the DatabaseCleaner project as places to begin contributing.
Basic memoization in Ruby
Memoization is an optimization technique that caches the results of expensive method calls to avoid repeating the same computation multiple times. The document discusses memoizing the current_user method in Ruby by using the ||= conditional assignment operator to assign the result of User.find(session[:user_id]) to the @current_user instance variable only if it is nil. This avoids duplicate database queries when current_user is called multiple times. The document also provides examples of when memoization should and should not be used, such as memoizing expensive calculations that do not change but not calculations that take parameters or can easily change.
Testing 101: Three Rules for Testing at Ombu Labs
In this presentation we talk about three rules that we follow every week to deliver high quality code. We prefer to write tests in this order: Integration tests first, unit tests later.
We don't do TDD religiously but it is a good idea when you're facing a very complex problem.
Think about your code as a black box and think about all the possible inputs and outputs, all the possible paths that a user might take, all the possible ranges that the user may enter.
Don't test only the happy path, keep in mind the odd cases.
Recycling at Ombu Labs
At Ombu Labs we decided to start recycling to improve the environment and as a contribution to our community.
This presentation has some basic tips on what needs to be recycle.

Cosa hanno in comune un mattoncino Lego e la backdoor XZ?
ABSTRACT: A prima vista, un mattoncino Lego e la backdoor XZ potrebbero avere in comune il fatto di essere entrambi blocchi di costruzione, o dipendenze di progetti creativi e software. La realtà è che un mattoncino Lego e il caso della backdoor XZ hanno molto di più di tutto ciò in comune.

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).

Observability Concepts EVERY Developer Should Know -- DeveloperWeek Europe.pdf
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:
Artificial Intelligence for XMLDevelopment
In the rapidly evolving landscape of technologies, XML continues to play a vital role in structuring, storing, and transporting data across diverse systems. The recent advancements in artificial intelligence (AI) present new methodologies for enhancing XML development workflows, introducing efficiency, automation, and intelligent capabilities. This presentation will outline the scope and perspective of utilizing AI in XML development. The potential benefits and the possible pitfalls will be highlighted, providing a balanced view of the subject.
We will explore the capabilities of AI in understanding XML markup languages and autonomously creating structured XML content. Additionally, we will examine the capacity of AI to enrich plain text with appropriate XML markup. Practical examples and methodological guidelines will be provided to elucidate how AI can be effectively prompted to interpret and generate accurate XML markup.
Further emphasis will be placed on the role of AI in developing XSLT, or schemas such as XSD and Schematron. We will address the techniques and strategies adopted to create prompts for generating code, explaining code, or refactoring the code, and the results achieved.
The discussion will extend to how AI can be used to transform XML content. In particular, the focus will be on the use of AI XPath extension functions in XSLT, Schematron, Schematron Quick Fixes, or for XML content refactoring.
The presentation aims to deliver a comprehensive overview of AI usage in XML development, providing attendees with the necessary knowledge to make informed decisions. Whether you’re at the early stages of adopting AI or considering integrating it in advanced XML development, this presentation will cover all levels of expertise.
By highlighting the potential advantages and challenges of integrating AI with XML development tools and languages, the presentation seeks to inspire thoughtful conversation around the future of XML development. We’ll not only delve into the technical aspects of AI-powered XML development but also discuss practical implications and possible future directions.
Securing your Kubernetes cluster_ a step-by-step guide to success !
Today, after several years of existence, an extremely active community and an ultra-dynamic ecosystem, Kubernetes has established itself as the de facto standard in container orchestration. Thanks to a wide range of managed services, it has never been so easy to set up a ready-to-use Kubernetes cluster.
However, this ease of use means that the subject of security in Kubernetes is often left for later, or even neglected. This exposes companies to significant risks.
In this talk, I'll show you step-by-step how to secure your Kubernetes cluster for greater peace of mind and reliability.

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.
