This document discusses how principles of being a good scout, such as leaving places better than you found them, can be applied to software development. Some ways to "be a good scout" in code include improving documentation, adding comments, refactoring code, writing tests, and cleaning up unused files or code. Being a good scout takes hard work, determination, ingenuity, and tenacity - qualities that also make a developer excellent at continually improving code quality.

Are you a good Code Scout
Scouts are taught to be adventurous, considerate, thoughtful, effective, diligent, ingenious, thorough, earnest and effective… All of these qualities are ones that we should be striving for as a Developer.
This talk intends to prove that being a Good Scout and being a Great developer are are pretty much the same thing. It will take you through the types of actions and attitudes that are taught to millions of kids aged seven to eighteen and compare it to what you should be practicing every day to make you a better Developer.
I'll tell you all the things you need to know to earn your very first Code Scout badge.
What schools should be teaching IT students
This document outlines essential skills and concepts that IT students should be taught, including source control, bug tracking, using compilers properly, automation testing, defensive programming, and soft skills like teamwork and open source contribution. It emphasizes practical skills like maintaining repeatable processes with makefiles and serious code editing tools. Students should learn core development practices like Don't Repeat Yourself (DRY) and thinking about full project and business needs rather than just individual assignments.
How to stay relevant - An evolutionary talk for testers
The software industry is witnessing a strong momentum in the adoption of agile and lean practices. Agile, Lean, Continuous Delivery, DevOps, Lean Startup have a massive impact on the role of testers. Discover how to stay relevant as a tester in a changing world.
Agille Testing Meetup 1
This document summarizes the agenda and discussion at an Agile Testing meetup group. It introduces the purpose of the group as a place for testers to share experiences and learn new skills in Agile Testing. Key topics discussed include the benefits of testing earlier in the development cycle using automated tools. A demonstration was given of a keyword driven web testing solution using WebDriver and FitNesse. Attendees then shared challenges with testing in Agile and ideas for future meetup activities.
Bringing Open-Source Practices to Your Day Job
Ben Coe is an employee at npm and lead maintainer of several open source projects. He discusses how open source best practices like automating tests, enforcing coding styles, and keeping dependencies updated can be applied in large corporations. These practices were designed for large asynchronous teams and using them internally, through a concept called InnerSource, can make developing enterprise software easier. npm and GitHub are working together to better integrate their tools and spread the message that open source practices benefit both open source and enterprise development.
Level Up Your Automated Tests
The document discusses ways to improve automated testing practices, such as by making tests easier to write, more readable, and more meaningful. It suggests using mocking frameworks to reduce test complexity, following standards and examples, and adopting a testing framework like Spock that addresses common issues. While progress has been made, there is still work to be done to encourage writing tests, make tests easy to write and understand, and ensure tests are meaningful and focused on the purposes of testing.
Level Up Your Automated Tests
Presentation given at GOTO Chicago that looks at why we don't like to write tests and one approach to improving automated tests that was taken by the MongoDB Java Driver team.
Open NTF OpenSource is collaboration at its best and matters
Christian Güdemann discusses OPENNTF and open source collaboration. He addresses common myths about open source like code being of poor quality or unsupported. Open source identifies problems and creates communities to solve them. Contributing features or fixes to IBM products is now easier through open source with OPENNTF. Resources listed include the OPENNTF, CollaborationToday, and XPages websites and YouTube, Twitter, and GitHub pages for OPENNTF.

Tips sukses berkarir sebagai developer dan programmer 2021
Tetap kembangkan skill mu di era pandemi. Jadikan hari-harimu lebih produktif dengan asah pengetahuan dan skill di Dicoding Event. Kali ini Dicoding LIVE disponsori oleh IDCamp dengan tema "Tips Sukses Berkarir sebagai Developer dan Programmer 2021"
Developer dan programmer kini menjadi salah satu pekerjaan yang paling diminati. Jadi, tidak heran jika banyak orang yang tertarik mencoba profesi ini untuk berkarir. Sayangnya masih banyak orang berpikir bahwa bekerja menjadi developer dan programmer hanya berhubungan dengan hal-hal yang bersifat technical, padahal tidak. Banyak hal yang harus dipersiapkan dan diketahui saat ingin mulai berkarier di dunia kerja seperti tools apa yang bisa membantu produktivitas, cara berkomunikasi dengan tim, sampai problem solving masalah dalam tim. Kali ini bersama dengan Andri Suranta Ginting (Mobile Engineer, Gojek) akan kita bahas tips dari pengalaman beliau dalam berkarir sebagai developer dan programmer juga menyiapkan hal technical dan non-technical untuk dikuasai di dunia kerja.

Teamleader testcon 2019
Testers, do you find yourself still siloed even after breaking down the “walls” between development and testing? Are you in a hole of never-ending test creation and maintenance, removing you from focusing on user experience? Does ad-hoc exploratory testing still happen because your tests aren’t stable enough to test the app before it gets to production?
When your team starts to adopt agile and DevOps development practices, how do you scale testing to keep up with higher release frequencies? Test automation is a big part of the solution. But beware that you’re doing it the wrong way.
In this talk I will explain how to reverse the negative impacts brought about from common – but not necessarily “good” – practices around automation tooling and QA hiring practices. I will talk about what changes you need to make to win back more time to develop and implement your test strategy. I will elevate your testing strategy from “surviving” to “thriving” in DevOps.

Morph your mindset for Continuous Delivery, Agile Roots 2014
This document outlines an agenda and content for a workshop on continuous integration, continuous delivery, and overcoming obstacles. The workshop includes presentations on key concepts, exercises for participants to collaborate in different roles and provide feedback, and discussions on challenges and experiments to try back at work. The goal is to help participants shift their mindset and learn techniques through interactive exercises to enable continuous delivery of software.
Starting with JavaScript
JavaScript can be used everywhere including web clients and applications. It is easy to start with JavaScript as there are many plug-and-play solutions available and you don't need to be a programmer. JavaScript is also easy to learn as the code is uncompiled and can be viewed directly, and there are many online resources and books available. The basic concepts of JavaScript like objects and conditionals are standard. To get started with JavaScript, all you need is a browser and text editor. Some gotchas to be aware of include differences across browsers, outdated examples, and reinventing solutions that frameworks provide.

Software testing presentation
Software development is hard! A common pattern in our field is project starting with the best of intentions and halfway through problems appear. Problems that slow us down, that will cause us to loose speed and flexibility. So, what is Test Driven Development and how it gives us back control over our projects?

РОМАН ЯКИМЧУК «Оптимізація QA процесів» Kyiv QADay 2021
Roman Yakymchuk is a QA consultant with 9 years of experience who provides QA process optimization services. He recommends using exploratory testing approaches, simplifying processes, automating repeatable tasks, and communicating effectively between teams. Key advice includes taking part in discussions early, learning about competitors, automating only worthwhile tasks, and sharing knowledge to prevent issues from a single person's absence. The goal of QA should be to prevent bugs rather than just find them.

This document discusses the benefits of JUnit testing and test-driven development (TDD) for XPages applications. It encourages testing from both a user and developer perspective to ensure functionality and catch errors. The TDD mantra of writing a test first, making it fail, then fixing the code to pass the test is explained. An example of a test for currency conversion is provided. OpenNTF's JUnit plugin for XPages is recommended to allow testing. Benefits of TDD like catching errors quickly, understanding requirements, and relaxing because code is tested are outlined. The talk concludes by recommending a book on TDD by example.
The secrets of building a team that can do everything
"Happy teams are all alike; every unhappy team is unhappy in its own way." - BlochSdoyevsky
Although every great team is somewhat different, all great teams have a common trait - they are composed of different characters that complete each other. So how do you build a team which will deliver fast over time with uncompromized quality and with joy of creation?
In this talk we will disscuss the different charcters of engineers, building a diverse team and how to make them work together so that the whole is greater than the sum of its parts.
Why You're A Bad PHP Programmer
You are a bad PHP programmer if you:
1) Don't plan before coding and fail to outline applications or comment code.
2) Sacrifice clarity through unclear naming and omitting syntax like curly braces.
3) Don't follow coding standards which leads to inconsistencies that are hard for others to understand.
4) Duplicate code without refactoring for reuse, violating the DRY principle.

5 unspoken rules of contributing to open source software v2
The document outlines 5 unspoken rules for contributing to open source software:
1. Justify your proposed changes by describing the feature and use case, prior art, and why your implementation is best.
2. Be willing to discuss and revise your contribution based on feedback to improve compatibility and address issues.
3. Maintain a positive and grateful attitude when interacting with the community to foster healthy collaboration.
4. Keep contributions small to simplify review and avoid overcomplicating projects with large change sets.
5. For significant new features, it is easier to create companion software rather than patching existing projects.

How I Learned to Stop Worrying and Love Legacy Code.....
Legacy Code. I never wrote it; everybody else did!
How many times have you waded through an ageing, decaying, tangled forrest of code and wished it would just die?
How many times have you heard someone say that what really needs to happen is a complete rewrite?
I have heard this many times, and, have uttered that fatal sentence myself.
But shouldn’t we love our legacy code?
Doesn’t it represent our investment and the hard work of ourselves and our predecessors?
Throwing it away is dangerous, because, before we do, we’ll need to work out exactly what it does, and we’ll need to tweeze out that critical business logic nestled in a deeply entangled knot of IF statements. It could take us years to do, and we’ll have to maintain two systems whilst we do it, inevitably adding new features to them both. Yes we get to reimplement using the latest, coolest programming language, instead of an old behemoth, but how long will our new cool language be around, and who will maintain that code, when it itself inevitably turns to legacy?
We can throw our arms in the air, complaining and grumbling about how we didn’t write the code, how we would never have written it the way it is, how those that wrote it were lesser programmers, possibly lesser humans themselves, but the code still remains, staring us in the face and hanging around for longer that we could possibly imagine. We can sort it out, we can improve it, we can make it testable, and we can learn to love our legacy code.

Aki Salmi - Refactoring legacy code: a true story @ I T.A.K.E. Unconference 2...
Talk delivered by Aki Salmi at I T.A.K.E. Unconference in Bucharest, 2014.
The presentation shows two example cases of introducing new features to the project. The first is a story of adding a search criteria to a list of 15 parameters.
The other example is total refactoring of handling files transferred to the system using FTP. It included both changes to the supported file types and the structure of the code.
In both examples, the end results are highlighted from both maintainability perspective and from business perspective.
How to write maintainable code - Peter Hilton - Codemotion Amsterdam 2017
The problem that new technology doesn’t fix is unmaintainable code. Clean code with good tests is essential, but not enough. This talk introduces techniques like getting better at naming, explaining code with tests, the few code comments you actually need, README-driven development and writing Minimum Viable Documentation. After the excitement of adopting new technology and software craftsmanship comes the horror of your next software maintenance project. As Jean-Paul Sartre said*, ‘Hell is other people’s code’. Whatever your level, your future happiness depends on maintainable code.
How to write maintainable code
Modern languages’ biggest problem isn’t having enough cool features, it’s unmaintainable code. The core of maintainable code is clean code with good tests, but that by itself is not enough. This talk introduces a range of techniques for writing and improving code for maintainability, including how to get better at naming, explaining code with tests, the few code comments you actually need, README-driven development and how to write Minimum Viable Documentation.
Attendees will see how to combine a number of techniques they have already encountered separately, plus at least one technique they’ve never heard of and can use immediately. Naming and abstraction are too hard to get right every single time, so you need to know when to add small doses of comments and documentation. More importantly, you need to know how to avoid wasting time on bad comments and unnecessary documentation without giving up entirely and not having any at all.
After the excitement of early adoption, and the joy of coding among experts comes the horror of your first maintenance project. As Jean-Paul Sartre said*, ‘Hell is other people’s code’. Whether you are a new Scala developer or an experienced team lead, your future developer experience and happiness depends on maintainable code.
Refactor your code: when, why and how (revisited)
Have you always heard about refactor and it always sounded like a foreign language to you? Have you tried to change code several times but found it impossible to make such changes in several projects? Do you feel overwhelmed when working with legacy code?
Let's see the benefits of refactoring your code and see some tips on how to do it safely!
We will start talking about what is legacy code, what we understand about refactoring and why it is so important nowadays when in most cases we work with software that others have written. Later we will share when we should start thinking on refactoring code and next we will see some recommended techniques to work with legacy code, which will even help us to know where to start and how. And finally, we will see in a live coding session some of the most important and useful refactoring techniques we could apply in our day-to-day job
At the end of this session, I hope you may have learned some tips on how to work with legacy code and how to apply certain techniques to make your day to day more enjoyable ;-)

Best practices 101
This document provides best practices for web development work. It includes recommendations to check emails and communication tools regularly, back up work, use child themes, thoroughly test any code changes, consider existing plugins, write detailed change logs, and thoroughly test sites before launching. Key practices emphasized are backing up work, using sandboxes for testing, creating child themes, understanding tasks fully before starting, and checking functionality across the entire site when implementing fixes or changes.
Building a Simple Theme Framework
My talk from WordCamp Philly 2012. I talk about some things you can do to generalize your themes to make a nice framework as a place for you to start!
30% faster coder on-boarding when you have a code cookbook
The document provides guidelines and wisdom for coding. It instructs readers to follow chapters and ask questions if anything is unclear. It emphasizes taking time to understand concepts rather than speed reading. Feedback is also welcome. Readers are advised not to be lazy and to follow the presented rules.
Make a better with clean code
This slide created for shared internal and for everyone interesting clean code. Why we needed? Why you should use it?
Ps. Sorry if my grammar is very bad :D
Ux testing recap
This document summarizes user experience testing conducted on Drupal 8. It describes the participants, testing scenarios, and findings. Key findings include terminology being an issue, certain tasks like placing blocks and creating content types being difficult, and recommendations to improve the user interface and onboarding experience. Suggestions include fixing block placement, improving field and quick edit UIs, and conducting a terminology review to make Drupal more intuitive and accessible to new users.
Putting the D&D in TDD
Are you tired of TDD workshops that make you do boring things like calculate
bowling scores and prime factors or demonstrate how to win at the game of
life? If so, this is the session for you! In this TDD workshop we will be
building the domain model for EverCraft -- a new MMORPG from Blizzards of the
Coast. We have lots of story cards prepared covering features from combat to
magic, classes to spells, and races to items. Plus, we'll be defining some of
these cards during the session in case you want that +9 knife of ogre slaying
or enjoy casting magic missile at the darkness.
This workshop is language agnotisic and for all levels of developers. The
focus is on TDD and emergent design but pair programming will be covered as
well. The only requirement is that you bring a laptop and that you be able to
test-drive you code with your language of choice. When you are done you will
emerge a better programmer for the experience but there is small chance you
will have a craving for Cheetos and Mountain Dew.
Life in the tech trenches (2015)
Presentation done at the "CTO Crunch" event by France Digitale, Paris, 24/02/2015.
Based on his experience (VP Eng @ Digiplug, CTO @ Pixmania, VP Eng @ Criteo, CTO @ Aldebaran Robotics and now CTO @ Viadeo), Julien shares some hard-learned, bullshit-free lessons on what it means to be a CTO.
Hiring, Tools, Methodology, Technology, Politics: welcome to Hell :)

Measures in SQL (SIGMOD 2024, Santiago, Chile)
SQL has attained widespread adoption, but Business Intelligence tools still use their own higher level languages based upon a multidimensional paradigm. Composable calculations are what is missing from SQL, and we propose a new kind of column, called a measure, that attaches a calculation to a table. Like regular tables, tables with measures are composable and closed when used in queries.
SQL-with-measures has the power, conciseness and reusability of multidimensional languages but retains SQL semantics. Measure invocations can be expanded in place to simple, clear SQL.
To define the evaluation semantics for measures, we introduce context-sensitive expressions (a way to evaluate multidimensional expressions that is consistent with existing SQL semantics), a concept called evaluation context, and several operations for setting and modifying the evaluation context.

Hand Rolled Applicative User Validation Code Kata
Could you use a simple piece of Scala validation code (granted, a very simplistic one too!) that you can rewrite, now and again, to refresh your basic understanding of Applicative operators <*>, <*, *>?
The goal is not to write perfect code showcasing validation, but rather, to provide a small, rough-and ready exercise to reinforce your muscle-memory.
Despite its grandiose-sounding title, this deck consists of just three slides showing the Scala 3 code to be rewritten whenever the details of the operators begin to fade away.
The code is my rough and ready translation of a Haskell user-validation program found in a book called Finding Success (and Failure) in Haskell - Fall in love with applicative functors.

Microservice Teams - How the cloud changes the way we work
A lot of technical challenges and complexity come with building a cloud-native and distributed architecture. The way we develop backend software has fundamentally changed in the last ten years. Managing a microservices architecture demands a lot of us to ensure observability and operational resiliency. But did you also change the way you run your development teams?
Sven will talk about Atlassian’s journey from a monolith to a multi-tenanted architecture and how it affected the way the engineering teams work. You will learn how we shifted to service ownership, moved to more autonomous teams (and its challenges), and established platform and enablement teams.
A Study of Variable-Role-based Feature Enrichment in Neural Models of Code
