The first part of an 8 part series covering the basics of the JavaScript language. This presentation covers variables, conditionals, loops and functions.
This sample offers insights of how qubit superpositions and entanglements are possible and how these are represented in statevectors, blockspheres and amplitudes when statevector representations are not possible
JavaScript has always been a language with quite a few dark corners and gotchas, which, if ignored, could lead to unexpected behaviours and bugs. While the new ECMAScript standard has helped clear some of these issues, it has also brought up some new ones like the Temporal Dead Zone, handling exceptions in Promises, or the behaviour of constants. This interactive presentation will go through a number of ECMAScript 6 features and their quirks, in an attempt to clear them up.

Modern web applications have constantly growing requirements and their complexity grows exponentially. Some of the biggest challenges in front of us are state management, testability, flexibility and on top of that we need to develop the application at reasonable level of simplicity in order to ease the recruitment process.
In this presentation I'll introduce a scalable Angular 2 application architecture, which answers the following requirements:
- Testability.
- Predictable state management.
- Scalable communication layer.
- Modular and robust design
Did you know that the .NET compiler turns our async methods into classes? And that .NET adds a try/catch block to each of these classes, potentially hiding thrown exceptions? It's true! In this session, we will learn how to best use async/await in C# by analyzing how .NET compiles our async code. Join me as we take an existing app and optimize its async code together, showing off performance gains, better exception handling, improved run-time speed, and smaller app size!
So you’ve developed an app in MongoDB Stitch? Now what? What is day-to-day use of MongoDB Stitch really like? We’ll talk topics like multi-environment deployment (dev → test → production); logging; testing and timing; and how to best make MongoDB and Stitch work for your application.
Каждый день появляется по новому JavaScript фрeймворку или новой технологии. И каждый день мы задаемся вопросом, как за всем этим успеть? Константин даст Вам серебряную пулю. Вы будете знать, как быстро разобраться в React, PostCss, RxJS, Redux, CycleJs, Angular и даже в неизвестном супер фреймворке. Увидим, что стоит за трендами технологий 2016.

The year is about to end, and I didn't publish reports about checks of open-source projects for a long time. Programmers asked me to check PostgreSQL Database Management System many times, and I've finally decided to do it. Unfortunately, this article isn't going to be large and interesting, as I found just a few typical bugs in the project. So, the report is pretty short this time.
This is a simple quantum circuit simulator example in Qsikit. This was run using Anaconda and Jupyter Notebook. This example demonstrates the first level of quantum circuit design, code and run in a notebook.

This session of The Ajax Experience 2008 takes a look at the latest features in both Prototype and script.aculo.us, including custom events and how to leverage them, method wrapping for AOP-style programming, sprockets, the refactorings and improvements on Ajax, scheduling and the DOM, the new effects engine, and more.
We wrap up with an overview of the community landscape for these libraries, looking at major helpful resources, prominent peripheral frameworks, and seeing what the future looks like for both Prototype and script.aculo.us.

Lisp Macros in 20 Minutes (Featuring Clojure)Phil Calçado
"We just started holding 20 minutes presentations during lunch time in the ThoughtWorks Sydney office. For the first session I gave a not-that-short talk on Lisp macros using Clojure. The slides are below.
It turns out that 20 minutes is too little time to actually acquire content but I think at least we now have some people interested in how metaprogramming can be more than monkey patching."

zkStudyClub - Reef: Fast Succinct Non-Interactive Zero-Knowledge Regex ProofsAlex Pruden
This paper presents Reef, a system for generating publicly verifiable succinct non-interactive zero-knowledge proofs that a committed document matches or does not match a regular expression. We describe applications such as proving the strength of passwords, the provenance of email despite redactions, the validity of oblivious DNS queries, and the existence of mutations in DNA. Reef supports the Perl Compatible Regular Expression syntax, including wildcards, alternation, ranges, capture groups, Kleene star, negations, and lookarounds. Reef introduces a new type of automata, Skipping Alternating Finite Automata (SAFA), that skips irrelevant parts of a document when producing proofs without undermining soundness, and instantiates SAFA with a lookup argument. Our experimental evaluation confirms that Reef can generate proofs for documents with 32M characters; the proofs are small and cheap to verify (under a second).

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.

Securing your Kubernetes cluster_ a step-by-step guide to success !KatiaHIMEUR1
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 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.
