Writing concurrent program is hard; maintaining concurrent program even is a nightmare. Actually, a pattern which helps us to write good concurrent code is available, that is, using “channels” to communicate.
This talk will share the channel concept with common libraries, like threading and multiprocessing, to make concurrent code elegant.
It's the talk at PyCon TW 2017 [1] and PyCon APAC/MY 2017 [2].

“We need to think about failure differently. Most people think mistakes are a necessary evil. Mistakes aren't a necessary evil, they aren't evil at all. They are an inevitable consequence of doing something new and as such should be seen as valuable. “ - Ed Catmull
As Go is a "new" programming language we are all experimenting and learning how to write better Go. While most presentations focus on the destination, this presentation focuses on the journey of learning Go and the mistakes I personally made while developing Hugo, Cobra, Viper, Afero & Docker.
7 Common mistakes in Go and when to avoid themSteven Francia
I've spent the past two years developing some of the most popular libraries and applications written in Go. I've also made a lot of mistakes along the way. Recognizing that "The only real mistake is the one from which we learn nothing. -John Powell", I would like to share with you the mistakes that I have made over my journey with Go and how you can avoid them.
Euro python2011 High Performance PythonIan Ozsvald
I ran this as a 4 hour tutorial at EuroPython 2011 to teach High Performance Python coding.
Techniques covered include bottleneck analysis by profiling, bytecode analysis, converting to C using Cython and ShedSkin, use of the numerical numpy library and numexpr, multi-core and multi-machine parallelisation and using CUDA GPUs.

Go for Object Oriented Programmers or Object Oriented Programming without Obj...Steven Francia
Object Oriented (OO) programming has dominated software engineering for the last two decades. The paradigm built on powerful concepts such as Encapsulation, Inheritance, and Polymoprhism has been internalized by the majority of software engineers. Although Go is not OO in the strict sense, we can continue to leverage the skills we’ve honed as OO engineers to come up with simple and solid designs.
Gopher Steve Francia, Author of
[Hugo](http://hugo.spf13.com), [Cobra](http://github.com/spf13/cobra), and many
other popular Go packages makes these difficult concepts accessible for everyone.
If you’re a OO programmer, especially one with a background with dynamic languages and are curious about go then this talk is for you. We will cover everything you need to know to leverage your existing skills and quickly start coding in go including:
How to use our Object Oriented programming fundamentals in go
Static and pseudo dynamic typing in go
Building fluent interfaces in go
Using go interfaces and duck typing to simplify architecture
Common mistakes made by those coming to go from other OO languages (Ruby, Python, Javascript, etc.),
Principles of good design in go.
From Promises & async/await to Async Algebraic Data TypesRobert Pearce
Small presentation for Charleston.js on the Async algebraic data type in JavaScript (demo omitted) as an alternative way to work with asynchronous control structures than Promises & async/await.
We're going to dive into function currying, function composition, eta-conversion and ramda.js in order to discover how we can refactor some JavaScript code to be point-free and give us concise, testable and reusable functions that express our intent.

A talk given at the August 2010 meeting of the Linux Users of Victoria. About using their mailing list of some 20,000 messages (since the start of 2007) with over 2 million words, as a demonstration of using a web corpus in NLTK (Natural Language Tool Kit), the Python library.
Some Functional Programming in JavaScript and Ramda.jsRobert Pearce
A small take on functional programming in JavaScript (JS) with Ramda.js. In the demos, we refactor updating a deeply nested object using the Ramda REPL and refactor analysis of UK rainfall data with Ramda and TypeScript.

JavaScript Libraries - Prototype and jQuery
http://www.refresh-events.ca/events/javascript-libraries-jquery-and-prototype/
Refresh Events is proud to present Cameron Westland (bigbangtechnology.com) and Eugene Andruszczenko (32teeth.org) for our first event of 2009. The topic of the evening will be an analysis of Prototype and jQuery, two increasingly popular JavaScript frameworks. Cameron and Eugene will perform deep-dives into Prototype and jQuery (respectively) and examine the benefits and drawbacks of using each language. The goal is not to see which one emerges as the “better language”, but instead to promote the concept of the right tool for the job.

Why do we need another build tool when we already have Ant? By focusing on convention over configuration, Maven allows you to declaratively define how your project is built, which reduces a lot of the procedural code that you'd need to implement in every build file if you were using Ant. This, along with Maven's built-in management of repositories for project dependencies, allows you to streamline your build process. Ultimately Maven can reduce the amount of time that would otherwise be wasted hunting down jar files and fiddling with boilerplate build scripts.
This presentation covers Maven's core concepts. It introduces the Plugin architecture, and explain how the most popular plugins are used. It also covers the POM concept and how it relates to dependency tracking and repositories.

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.
Enhancing Performance with Globus and the Science DMZGlobus

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.
