How to hack a node app?

Thought hacking was hard? It’s not, it’s easy and I’m going to show you how! In this episode of CSI Sofia we’ll investigate a series of hacking stories and break them down step-by-step to see exactly how they did it. By the end you’ll walk away a little bit more scared and a lot more prepared with some great practices you can apply immediately to your own applications.

Building scalable web apps for patients

Digital healthcare was and it is still an important part of the healthcare worldwide. Last couple of years many companies invested in developing solutions that enhance the efficiency of healthcare delivery and make medicines more personalized and precise. Come to this presentation to learn what it means to build scalable web apps for patients. We will talk about JavaScript/React. Its ecosystem and how it helps to deliver sustainable software.

How technology helps therapists connect and work remotely with their patients

What Firebase, wearable devices and WebRTC have to do with the medicine? Often after a surgery patients have really hard time finding the rehabilitation services that they need. Although it sounds like a healthcare system problem it is sometimes caused by problems that could be overcome by technology. Traditionally the healthcare industry is slow to adopt modern technology but the rehabilitation and tele-rehabilitation in particular give us an opportunity to innovate a bit more aggressively.

For the past couple years we’ve been developing a solution in the fields of telemedicine that utilizes a real-time database such as Google Firebase, uses smart wearable devices such as smart bracelets and watches to collect valuable data, real-time audio-video communication such as WebRTC to connect people over the Internet. In this lecture we will discuss some of those technologies as well as some of the problems specific for the industry.

Machine Learning in the browser with deeplearn.js

Even if you've never done anything with machine learning, you have probably already heard that it's very powerful, adaptive and will change our way of thinking about computing forever. But how can you, a web developer, who's never been interested much in statistics benefit from the ML hype? In this talk I want to give you the tools to build a small self-learning application that runs completely in the browser.

Bulding Decentralized Apps

While creating a decentralized app is certainly fun, there are some peculiar details which you need to have in mind when considering the architecture of your project. In the form of an open discussion Emil Stoyanov will share his experience with building decentralized applications and will go through the process of creating Dapps based on Ethereum blockchain and decentralized storage technologies like IPFS. The discussion involves the basic principles of operation of a blockchain and how it intergrates with the existing web technologies, but does not require any prior knowledge about how Ethereum or other decentralized solutions work.

The Big "Why Equal doesn't Equal" Quiz

So you think you know PHP ? But do you really ?

We all compare and test data on nearly every other line in our code, be it input validation, an if-statement, a switch or determining what to display and how. So of course we are all experts on how to do these tests and comparisons…. Or are we?

No matter whether you are a beginner or an expert, come and join in the fun for the Big “Why equal doesn’t equal” Quiz, test your knowledge and learn about defensive programming and the quirks of a loose type programming language along the way.

Game principles in design

“Man…is only fully a human being when he plays” - Friedrich Schiller.

Game is a constant part of human nature and can be seen in almost every facet of civilisation: war, religion, politics, sports and arts. It is an activity executed within certain limits of time and place, having its aim in itself and accompanied by a feeling of tension, joy and the consciousness that it is different from “ordinary life”.The play-mood is a social impulse that conveys meaning to certain actions and is a source of intrinsic motivation for the player. We will analyse the anatomy of a play and will discuss how to smartly use game principles in products in order to keep and guide users interest.

Understanding the Job to Design the Service.

What does it mean for design to be intersectional, for development to be inclusive? What does it mean to be a designer in an era of rapidly changing complexity? Combining insights from the jam methodology, user centred design and jobs to be done framework, this talk will explore how we can incorporate uncertainty to create adaptive personas where the objective and the personal meet.

Building a global internet of things network together.

The Things Network is building a network for the Internet of Things by creating abundant data connectivity, so applications and businesses can flourish. The technology we use is called LoRaWAN and it allows for things to talk to the internet without 3G or WiFi. So no WiFi codes and no mobile subscriptions. It features low battery usage, long range and low bandwidth.

Get your ETL flow under Control using 3sigma limits.

I would like to demonstrate how to use this simple statistical rule to capture outliers represented as invalid file loads in your etl process and pass them as documents into elasticsearch.setup will consist of Sql server hosting your etl Logging database, scheduled, stored procedure calculating The empirical rule and raising events into The windows event Log ,winlogbeat passing these events to elasticsearch and also kibana will be used for visualization. During The presentation, I would like to show how to get this setup running on your local machine to try out and talk further about The pros / cons of this solution.

Data Quality by Design

How do you define Data Quality? I certainly had trouble when I faced that same question for the first time. Twelve months later, I feel I have a grip on it, and as we prepare to roll out a plan to address it across our organization, I’d like to share with you a way of looking at, analyzing, planning and implementing a plan for data quality improvements.

Working the right way by knowing all the wrong ways.

Software development is a strange mixture of work and art. We do not only write code, but we make art as writers create their masterpieces. Your habits reflect on your daily work and shape how you approach new tasks. The main problem of bad habits, aside of wasting your time and lowering your motivation, is that rather often you don’t even know about them. I will talk about bad habits by sharing with you all of the bad practices that I remember from my past and current projects. I will talk about what helps me write better, what motivates me and what prevents me from doing so. I will tell you how I started with Delphi, PHP and JAVA, how I hated JavaScript and how I love it now. We will even briefly talk about DevOPS and how I had to develop a torrent client in Python. I’ll share how I manage to learn new things, despite my uncanny laziness for reading.
