For attackers, obtaining access to a Windows workstation with limited privileges can really put a damper on your day. Low privileged access can be a roadblock for even the most skilled "undocumented administrators". Local administrator access to a windows machine within an active directory domain often results in the ability to compromise the whole domain. This talk will walk through how attackers and defenders can learn to identify and exploit practical Windows privilege escalation vectors on the Windows 7 OS.

A talk describing our experiences building monorepo at Pinterest.
This talk was presented at Mobile Summit'18 held at CapitalOne in SF on May 22, 2018.
This is the slide deck I presented at the first CommCon event in the UK: it goes through some of the possible strategies for scaling WebRTC applications, mostly if you're using Janus but not only.
A collection of techniques that allow users to escalate privileges to local administrator and then to NT Authority\System. On a windows domain readers can use the described techniques to escalate to domain administrators.
These are the slides for the presentation I shared at the virtual edition of IIT-RTC 2022. I talked about how cascading/scalability worked with Janus 0.x, and what steps we've taken to do the same for 1.x (multistream) as well. In particular, the focus is on the new integrated cascading support in the VideoRoom plugin.

An introduction to configuring Domino for DockerGabriella Davis
9.0.1 FP10 brings support for Domino on a docker platform. You may know that docker is a container solution but what does that mean and how could it affect your Domino infrstructure? In this session we'll review how to install and run Domino in a docker container, whether it can support external clustering and the decisions to consider when designing container architecture.
Testing within a closed system is easy. Everything is generally accessible and can be interacted with freely. But what happens when the application requires integration with one or more third parties in order to function? In unit tests, we can use mocks and there are many Ruby libraries to make that happen. However, this doesn’t help us much when we’re testing deployed code in end-to-end scenarios or exploratory tests. The solution I found was to build a mock application to mimic the third party. This talk will cover the process and tools used to build the application, the advantages/disadvantages it provides, and explain how this mock is utilized in real-world situations.

Mockito vs JMockit, battle of the mocking frameworksEndranNL
(Original keynote slides can be found at https://github.com/Endran/PublicSlides)
For years the industry standard of mocking on the JVM has been Mockito. Mockito is a wonderful library that really speeds up your testing by allowing you to create mocks in a very simple way. That being said, it does have its drawbacks, for which different strategies need to be deployed to keep your code testable. The main drawbacks are statics and finals. Final classes cannot be mocked, nor final methods, and also static methods are a no-go. To work with these type of things we need to wrap it, and copy the signature in a non final, non static way.
I have a great adversity against statics, I've devoted an entire post about it, in short; It hides dependencies and brings so little convenience at the costs of its drawbacks. Finals on the other hand have purpose, it helps messaging the goal of a class or method. Java is one of the few languages where classes and methods are open/virtual by default and have to be closed/final by explicit action. In (for example) Kotlin, everything is final by default, if you do not want something to be final, you should use the open keyword.
No matter if you follow the principle of making things final, static or not, if you are using Mockito the decision has been made. This mocking framework demands that everything is non-final, demands that everything is designed to be extended, since it might need to be mocked away. We should be able to improve upon this, and by the name of this post, you should be able to guess which framework will save the day. JMockit will help us with our impediments, and will give some other nifty benefits as well!
Popular Git Workflows You Haven't Heard AboutAtlassian
When you adopted Git you either researched an effective workflow or someone in your team chose it for you. Maybe you use Gitflow, maybe a lightweight master/develop system like the Bitbucket Cloud team, or maybe you have long-running maintenance branches.
Done right, all these workflows can be very effective for your team. But why is the Git project itself run by e-mailing patches to an old school mailing list? Why do you hear of cool companies like Twitter use huge mono repos and embracing patch queues? To answer these questions we need to go deeper. This talk will show you the cool side of Git workflows you are probably not using.

Nowadays we all seem to be working with small independent services that need to talk with numerous other services. This is a problem because when developing your service, you need to have a working environment—but bringing up all your dependencies is often not an option.
In this talk, I will take you through our journey of creating a mock server to increase dev speed, and how it allowed us to write better tests.

SXSW Interactive is amazing this year! I’m talking VR, AR, IoT, enter next acronym here, and even the P.O.T.U.S. made an appearance.
SXSW plays an increasingly important role in revolutionizing interactive media. While often known as a hotbed for tech startups, it’s the discussions around practical applications of such media, the opportunities they present, and the surrounding implications that have attracted the attention of a growing number of brands, platforms, and creators each year.
In this webinar we share key takeaways from SXSW 2016 and discuss what each means for the year ahead.
Apple's next press event happens on Monday, March 21 at the company's campus in Cupertino, California.
We've already talked about what to expect, in our PPT but to recap: Apple is expected to announce a new 4-inch iPhone that combines the size of the iPhone 5S with features from the iPhone 6 and 6S. It will also supposedly be upgrading the 9.7-inch iPad, giving it updated internals, a Smart Connector, and Apple Pencil support imported from the iPad Pro. The Apple Watch may get some love in the form of new band colors and combinations, but rumors say not to expect a full hardware refresh just yet.
Creative Traction Methodology - For Early Stage StartupsTommaso Di Bartolo
How to build a mindset that gets a new product traction? 99% of all startups are forced to give up because they lack traction. As founders are thrilled and captivated to build a product that could change the world - the majority downright neglects to put equal efforts towards how to differentiate in taking the product to market. The difference between those who make it to get traction and the rest lies in the innovator’s mindset.

Unit testing is an important part of development, but does not always get the attention it deserves. In this session we will discuss how to write truly automated unit tests that run without any manual setup or special configuration, as well as producing Python code coverage reports within OPNFV Jenkins to ensure that the important paths are being tested. Additional topics include how to have code coverage part of the Gerrit review cycle to ensure compliance. Use of Python nosetest, mock and Coberatura code coverage will be discussed.

Don't get blamed for your choices - Techorama 2019Hannes Lowette
As developers, we make choices all the time: architecture, frameworks, libraries, cloud providers, etc. And if you’ve been around for a while, you probably ended up regretting at least some of your choices.
In this session, we'll explore the typical pitfalls of making development choices and how to avoid them. By the end of this session, you will be armed to take any decision they will throw at you.
Now, if only there was a way to prove to your peers and superiors that you acquired this skill...
Well, there is! RAD Certification! I'll end my talk by telling you about this awesome certification program!
TDD - Seriously, try it! - Trójmiasto Java User Group (17th May '23)ssusercaf6c1
Have you heard of TDD? Are you interested or familiar with this practice but have never been able to understand it?
Join this session to see the benefits of Test-Driven Development (TDD), understand how it works and its benefits. In a more detailed approach, we will see this way of developing software, where our code is always built guided by tests.
We will go over some history about TDD, which is the main process we must follow when we work with this mechanic and the rules that surround it. We will also list the main advantages and disadvantages that most developers who practice TDD find and whether the arguments in favour add up to more than those that subtract. Finally, we will review some good habits and practices when applying TDD and see how to do it step by step with an example of a "live" coding session with Java.
At the end of the session, I hope that you will have a wider understanding of what TDD is, what advantages it brings, why it is interesting to master it and also that you will take with you some tricks and good practices to be able to apply them in your day-to-day life when writing code

Quickly and Effectively Testing Legacy c++ Code with Approval Tests mu cppClare Macrae
Presented at MUC++, 6 August 2020
Links from this talk are at: https://github.com/claremacrae/talks/blob/main/Quickly_and_Effectively_Testing_Legacy_C++_Code_with_Approval_Tests.md#top
Abstract:
You've inherited some legacy code: it's valuable, but it doesn't have tests, and it wasn't designed to be testable, so you need to start refactoring. But you can't refactor safely until the code has tests, and you can't add tests without refactoring! How can you ever break out of this loop?
Whether Legacy code for you means "old code", "code without tests", or "code you wish to redesign for new features or unit-tests", this talk will enable you to become productive and work safely, quickly.
The simplicity, convenience, ease-of-use, power and flexibility of Llewellyn Falco's "Approval Tests" approach has long been proven in a dozen programming languages. And now all this is now available to C++ developers too!
Clare will present a small but surprisingly effective C++11 library for applying "Approval Tests" to cross-platform C++ code - for both legacy and green-field systems, and with a range of testing frameworks.
She will demonstrate its use in some real-world situations, including how to quickly lock down the behaviour of legacy code. She will show how to quickly achieve good test coverage, even for very large sets of inputs.
Attendees will discover some quick, practical techniques to use for common challenges that can be applied very easily using Approval Tests.
Join this session to see the benefits of Test-Driven Development (TDD), and understand how it works and its benefits. In a more detailed approach, we will see this way of developing software, where our code is always built guided by tests. We will go over some history about TDD and list the main advantages and disadvantages that most developers who practice it find and whether the arguments in favour add up to more than those that subtract. Finally, we will review some good habits and practices when applying TDD by seeing how to do it step by step with an example of a "live" coding session with Java.

Алексей Ященко и Ярослав Волощук "False simplicity of front-end applications"Fwdays
It’s easy to underestimate a front-end project's complexity, which leads to shallow and thus incorrect implementation. Attempts to fix this problem result in uncontrolled complexity growth and undefined behavior in corner cases.
We'll discuss ways of revealing the inherent complexity of a problem and dealing with it both on theoretical and practical levels.
DCSUG - We Are The Leaders We Have Been Waiting For by Lyssa AdkinsExcella
WE ARE THE LEADERS WE HAVE BEEN WAITING FOR:
AGILISTS AND OUR VALUES ON THE LEADING EDGE OF HUMAN DEVELOPMENT
If we Agilists value individuals and interactions over processes and tools, why do processes and tools so often run the show? In this talk, Lyssa offers two good reasons why she thinks this is so and shows the way out with some solid, but not well known, human technologies. Using eye-opening adult human development models, this keynote lays out the challenging terrain we need to traverse -- which is for us to get good at helping people in organizations develop their mental capabilities, not just change their mind-sets. When this happens, we will be able to help organizations do more than just "talk the talk" about valuing individuals and interactions over processes and tools (as well as fully living into all of the other Agile values). It's a big challenge but we are up for it! It turns out that our community at large is on the leading edge of adult human development and, if we can develop ourselves, we can help others do the same. It's our time. We are the leaders we have been waiting for. Lyssa will show you why this is so, give you some food-for-thought about your own development and offer practical ways to help develop others so that the full promise of Agile comes true more often.
Let's Sharpen Your Agile Ax, It's Story Splitting TimeExcella
This slide deck is from the recent presentation Brian Sjoberg gave at the DC Scrum User Group on August 25, 2016. It is about User Stories and how to split them.
Do you want to write great User Stories (a.k.a. small features that are part of a product) that provide the vehicle for conversation and confirmation that we build the right thing? Do you struggle with splitting stories so that they still provide business value but can be accomplished within a fraction of your iteration and be potentially shippable to production? We will do a quick refresher on User Story formatting to include Acceptance Criteria. Additionally we will learn techniques for splitting stories in this interactive workshop.

The 7 Secrets of Highly Effective Retrospectives (DCSUG)Excella
Slides from the DC Scrum User Group event on 4/25/2016 titled, "The 7 Secrets of Highly Effective Retrospectives" by David Horowitz.
http://www.meetup.com/DC-Scrum/events/228807928/
Retrospectives are the core of agility. And yet they are often the scrum ceremony that is most frequently skipped. Many teams like the idea of the retrospective but find them boring, or worse ineffective.
Join Retrium CEO and Co-Founder David Horowitz as he reveals seven secrets that lead to effective retrospectives. You'll learn:* The best way to ensure your retrospectives lead to real change* The "pledge" everyone on your team must take before participating* How to know who to include in each retrospective* The single most important thing you can do to keep your team engaged during the retro* And much, much more!
Want to bring your productivity to the next level? Let's gain a desire based on an experience to make this happen.
Are you struggling with delivering a potentially releasable working product every iteration? Ever wonder what one of biggest reasons we have difficulty getting things done at the individual, team and organizational level are? Do you keep doing something even though you know it reduces your productivity and lowers quality? We are going to run an exercise that highlights one of the major culprits that you have all experienced and continue to experience. The exercise will likely ignite a little fire that will help you become more productive and improve the quality of your work. We will also discuss ways to improve this at the individual, team and organization levels. Learning Objectives for this presentation are as follows:
- Gain an understanding, through an exercise, of the cost to productivity a common habit has, that many of us indulge in.
- A new found desire to fix one of the major issues that reduces productivity and quality.
- 2 approaches to fixing the issue.

Tactics to Kickstart Your Journey Toward DevOpsExcella
You’re probably a believer in the benefits of continuous delivery and DevOps (why else would you be at this meetup?). The rest of your organization... maybe not so much. Maybe you’re getting pushback on changes you believe will make your organization better. Maybe you’re not sure where or how to start to give yourself the best chance of making a change that will work. I’ll give you some tactics to start your journey toward DevOps (or toward any meaningful change, for that matter). I’ll also show how you might apply those tactics to address a specific challenge: adding test automation to a large legacy codebase. The goal is that you walk away with more tools in your “change toolkit” and a little more enthusiasm for shaking things up for the better where you work.

Using Lean Thinking to Increase the Value of AgileExcella
“Agile doesn’t have a brain.” This quote from Bill Scott, VP, Business Engineering and Product Development at PayPal, is provocative for sure, but it spotlights the notion that in most organizations Agile is primarily applied as a downstream engineering approach that isn’t inherently concerned with optimizing product design and user experience, the determinants of value to the customer. The learning cycles that form the basis of Scrum are focused on verification and validation of user needs as they are already identified in the backlog’s user stories, but provide little guidance on how to translate organizational goals and customer needs into the backlog’s content and relative priorities in the first place. As a result, the danger persists that Agile teams end up very efficiently building products that implement an incomplete and subjective perception of customers’ wants and needs.
This presentation explores how Lean thinking can expand the “inspect and adapt” cycles of Agile development beyond implementation and help to systematically determine which features and design choices really provide the greatest customer value. After a brief introduction to Lean concepts, the presentation discusses how Lean approaches product development as a series of hypotheses about customers’ value perception and builds on Agile’s rapid iterative delivery of working software to test these assumptions. Finally, it highlights ways to derive testable assumptions from organizational goals, such as the Lean UX Hypothesis Statement template and Gojko Adzic’s Impact Mapping.
Lean is having an increasingly pervasive presence in the software world these days. Lean Software Development has its seven principles and seven wastes and promises to improve efficiency and quality. Many of the most innovative software development companies profess to have their philosophical home in Lean Startup's 'Build-Measure-Learn' approach, rather than Agile. But is Lean the same as Agile? And what about the proponents of Lean UX who are challenging the emerging orthodoxy of Agile SDLC frameworks with slogans like "Agile doesn't have a brain"?
In this session, we will explore the basic ideas of Lean thinking, similarities and differences between different flavors of Lean, how Lean can be applied to software development, and finally how Lean concepts can be used to expand the built-in 'inspect and adapt' cycles of Scrum to include learning about customer value.

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. 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
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.
PHP Frameworks: I want to break free (IPC Berlin 2024)Ralf Eggert
In this presentation, we examine the challenges and limitations of relying too heavily on PHP frameworks in web development. We discuss the history of PHP and its frameworks to understand how this dependence has evolved. The focus will be on providing concrete tips and strategies to reduce reliance on these frameworks, based on real-world examples and practical considerations. The goal is to equip developers with the skills and knowledge to create more flexible and future-proof web applications. We'll explore the importance of maintaining autonomy in a rapidly changing tech landscape and how to make informed decisions in PHP development.

"Impact of front-end architecture on development cost", Viktor TurskyiFwdays
I have heard many times that architecture is not important for the front-end. Also, many times I have seen how developers implement features on the front-end just following the standard rules for a framework and think that this is enough to successfully launch the project, and then the project fails. How to prevent this and what approach to choose? I have launched dozens of complex projects and during the talk we will analyze which approaches have worked for me and which have not.

4. Really though, who are you?
• Came from Java world
• Python developer for 2 years
• DevOps
– Lots of work with automation and quality
• Passionate about quality!
– Doesn’t happen overnight…
6. • Became a Certified Scrum Developer
(CSD) about 2 years ago
• Finally learned about craftsmanship and
writing better tests
– Basically black magic
• Learned in Java…
I want to be a better developer
7. • Switching to Python was jarring
• Kept wondering about writing unit tests
• Dealing with complicated frameworks like
Django
Finding Python
7
8. • Asked colleagues
– Many had the same questions
• Decided to learn…
• Wanted to share with the community
Unit testing? Mocks?
8
11. • “They’re good when the problem is easy”
– A rabbit hole of testing
• “I spend too much time writing lots of code
to test, so I give up”
• “There’s just some stuff you can’t unit test”
Great Unit Testing Myths
13. What Are Mocks?
13
Test Double
Dummy
Object
Test Stub Test Spy
Mock
Object
Fake
Object
Commonly referred to as “Mocks”
14. • Stubs
– Provide a canned response to method calls
• Spy
– Real objects that behave like normal except
when a specific condition is met
• Mocks
– Verifies behavior (calls) to a method
What Are Mocks?
14
16. • Eliminates dependencies in the CUT
(class under test)
– Isolated Unit Tests
Problems Mocks Solve
16
foo(x) bar(x)
17. • Tests methods that have no return value
Problems Mocks Solve
17
How do we know that bar(x) has been called?
18. • Tests error handling
Problems Mocks Solve
18
How do we generate this exception???
19. • Eliminate dependency on database calls
– Speed up testing!
• Reduce test complexity
– Don’t have to write complex logic to handle
behavior of methods not under test
• Don’t have to wait to implement other
methods
Other Reasons Mocks Are Important
19
21. • Mock (MagicMock)
– Most robust, popular
– Built-in as of Python 3.3!
• flexmock
– Based on Ruby’s flexmock
• mox
– Similar to Java’s EasyMock
• Mocker
• dingus
– “record then assert” mocking library
• fudge
– Similar to Mockito
• MiniMock
– Simple mocking with DocTest
What Are The Python Options?
21
24. • Create a method to return a new, random
victim candidate
– Must not show the same person
– Must not show someone the user has already
“swiped” on
Problem: “Docker” dating app
25. Easy enough…
25
“Surely no one could
have seen EVERYONE
in the database!!!”
- The Intern
get_next_person() get_random_person()
42. • Use patching / mocks to bring certainty to
method calls
• Eliminates dependencies on other code
– Even unfinished code!!!
• Lots of ways to do it, pick your favorite
Recap: What did we learn?
42
45. • When a user swipes right…
• If the other user “likes” them:
– Send them both a message with contact info
• If the other user “dislikes” them:
– Let the user down gently…
• If the other user hasn’t evaluated yet:
– Display the “give it time” message
Problem: “Docker” matches
61. • open() returns a File object
• open(filename).read()
• So we really need to mock File.read()
– But it’s an instance!!! Oh no!
What? Why Not???
61
Have you tried solving it with Mocks???
67. • Mocking makes writing unit tests simpler
– Eliminates dependencies
– Verifies behavior
– Tests error handling
• You just need some practice!
Remember This!
