Read on to see what one DZone Zone Leader learned at the iTake conference, including new perspectives on testing, BDD, security, and mob programming.

I have been a Docker fan since almost day 1, working for a company that packaged its project to work in containers early-on, writing many blog posts on usage and related tooling, attending meetups here in Berlin and contributing to two code sprints as a mentor. Late last year I gave a talk at LinuxCon in Berlin to see Solomon Hykes (Founder) sat in the front row, a nerve-racking delight.

I am not the best public speaker or presenter, but I give lots and enjoy giving them. I also attend many meetups and conferences and so have built a good repertoire of what works and what doesn’t. I have been planning this post for a while, but after a particularly poor presentation last week from a major technical project disappointed me, I felt motivated to get off my backside and write it. Part 1 (of an undecided number) covers stagecraft and vocal techniques.

Notifications: you probably love them or hate them. I like them when they are useful to me, and this is something that the OpenBack SDK attempts to solve. It offers a framework for you to make your in-app notifications more than annoying notices, but tailoring them to users contexts and allowing them to do more with notifications.

Speech synthesis is a not a new technology — computers have been attempting to speak to us for decades — but with the recent rise of voice-activated appliances, speech synthesis is undergoing a renaissance. At more than one meetup I heard Speech Synthesis Markup Language (SSML) mentioned for modeling computerized speech and thought it warranted further investigation.

Released earlier in 2017, Docker’s new native applications for Windows and Mac replaced the older methods for running Docker on Windows and Mac and created a better experience for developers using those platforms.

I remember the first time I tried the image recognition technology in the Google translate app, snapping a poster to instantly translate what it said into a language I understood. It was far from perfect, but it was cool, and it showed the potential of what more traditional optical character recognition could be used for.

Ruby is a wonderful language for beginner coders to start with and scale to large, distributed Web and Desktop applications. It has an accepting and helpful community and strives to keep itself up to date to match the needs of developers.

You jet around the world, a road and sky warrior armed with a laptop in search of a power socket and decent WiFi. No ties, no responsibilities; work when you need it and when you’re bored, you move on. Sounds perfect, doesn’t it?

I would never call myself a real programmer, but I have a healthy obsession with studying new languages that emerge, especially those that arrive with little baggage and attempt to solve current problems and new use cases. This brought about my explorations in recent years of Swift and Kotlin, both initially aimed to fix issues with the languages traditionally used in their worlds, but rapidly became used in more widespread contexts, and generally, have enthusiastic communities.

Much has been written already about Israel’s incredibly successful and mature tech startup scene, but I was lucky enough to be asked to speak at Codemotion in Israel, so thought I would line up interviews with local entrepreneurs, catch some sun, and enjoy the food that Tel Aviv is famous for (and I wasn’t disappointed on that front). I barely scratched the surface of what the city (and country) has to offer, but I hope you will find those I spoke to interesting and useful.

Stack Overflow's 2017 developer survey crossed my desk at the same time as a report on tech wage trends from Dice.com, who I’d never heard of before, but the report echoed many of my own observations, so I read further. It’s only from US data, but again, I have seen similar trends in other countries, so thought I’d share insights with you, in case, you know, you’re looking for a change, or are inquisitive about your worth.

I’ve never been to CeBit before, but it’s reasonably well-known on the tech conference circuit for announcements, and as it’s only a two-hour train ride from home, I jumped on a Deutsche Bahn and headed to the Worlds largest fairground in Hannover.

When most people think about the Internet of Things (IoT), it likely conjures ideas of activity-monitoring wearables like Fitbit or home devices for home security (iSmart), lighting (Hue), and coffee makers (Nespresso Prodigio). It’s a mixed opinion on the success of consumer IoT devices, but IoT is making its biggest impact in the industrial realm, where it’s used to reconcile problems that have plagued workplaces for centuries. Industry can use sensor technology to increase efficiency, improve...

With the UK exiting the European Union, Germany is jostling to become the new FinTech capital of the EU. Frankfurt has the history and established finance industry, but Berlin is more affordable, is larger, and has a more diverse population, looking at challenges from different perspectives. With at least six regular blockchain and cryptocurrency related meetups, founding members of Ethereum and Monax present in the city, and countless cryptocurrency related projects, analysts are beginning to c...

I’m sure we’ve all been there. That moment when you realize that important and sensitive access details have leaked online into a public space and potentially rendered your services to unrequited access. With the ever-growing amount of services we depend on for our development stack, the number of sensitive details to remember and track has also increased. To cope with this problem, tools have emerged in the field of “secrets management.” In this post, I am going to look at Docker Secrets, the n...

Cloud Next is Google’s regular conference that covers all their cloud-related products. That’s something of a vague and overarching classification, but I squeezed into the Google office in Berlin to watch a live stream of the event and will get you all up to speed.

Two experiences in my life have shaped the way I try to talk about technology. One was over ten years ago when I taught a room full of retirees, long-term unemployed, and recent immigrants basic computer skills. I realized that I could throw many of the subjects I had studied out of the window and that the best way to teach people was to give them a reason to learn. Fast forward to last year (and a subject I wrote previously on SitePoint) when I taught programming to a group of recent Syrian ref...

There is a lot to see, hear, and discover at Mobile World Congress (MWC) and its many side events. From helping the developing world, to brain imaging, and sensors on seals, these are some of my highlights.

2016 was quite a year for technology and its impact on the world. Subconsciously or not, nestled amongst the booths of generic Chinese handsets and app marketing companies were many projects and people at MWC that sought to accomplish something more meaningful. Here are some of the themes and concepts I feel will shape 2017 and 2018.

Python is a wonderful language, ideal for beginners, and easy to scale up from starter projects to complex applications for data processing and serving dynamic web pages. As you increase complexity in your applications, it can be easy to inadvertently introduce potential problems and vulnerabilities. In this article, I will highlight the easiest to miss that can cause the biggest problems, how to avoid them and tools and services that help you save time doing so.

There are currently two major issues and trends with application development. One is users finding your efforts, and the other is then making money when they do.

After using macOS for over 20 years I was interested to get new perspectives and try other operating systems in my daily work. In this second part, I spend a month with Linux.

Drawing my short series to a close (we’ve talked about testing code examples in documentation and automating spelling and grammar checks in documentation), let’s cover one of the hardest elements of documentation to create and keep up to publishDate: screenshots.

Android finds itself in interesting times. Google has begun creating it’s own ‘premium’ versions of the operating system (OS), Cyanogen have ceased development, and many feel that Android will change name or shape in the near future.

Creating a modern and feature-rich mobile app has never been a simple task, but is now more complex than ever. There are a plethora of platforms, programming languages and strategies to consider, and knowing where to start and what path to follow involves understanding and appreciating a lot of interconnected components.

After using macOS for over 20 years I was interested to get new perspectives and try other operating systems in my daily work. In this first part, I spend a month with Windows.

Last year at IFA I came across a small stall lurking within a gathering of startups. The booth was full of blinking small blocks, motors and switches that aimed to help children learn to code. Fresh from my experiences and reflections teaching Syrian refugees to code, [I have been pondering the best ways to do so ever since](https://www.sitepoint.com/teaching-programming-whats-the-best-language-for-beginners/). In a series of posts that will cover a variety of projects, and a broader summary post, I intend to look at a variety of different techniques for teaching coding, especially...

2016 has been an eventful year in many, many ways. I don't want to dwell on big global topics in this post, but review what I got up to. ## Writing {% assign 2016posts = site.posts | where:"date","2016" %} In 2016, I wrote approximately {{ 2016posts.size }} articles, blog posts and tutorials. The most popular on my Medium account was '[A documentation crash course](https://hackernoon.com/a-documentation-crash-course-45006a85c15c#.790b6ze0w)', closely followed by '[Making Atom even more awesome](https://hackernoon.com/making-atom-even-more-awesome-my-setup-e7a89969a876#.s2yhf3joo)' and '[Tech your privilege at the door](https://hackernoon.com/tech-your-privilege-at-the-door-5d8da0c41c6b#.eemgzrjyd)' (which was only published a week ago)....

In my last post, I covered how to improve the written component of your documentation with automated spell-checking and suggestions for better writing. In this post, I’ll cover the code component of good documentation; trying an example and finding it doesn’t work is a sure-fire way to annoy a reader.
