Learn Python & Selenium the fast way

This workshop will teach the basics of Python: functions, common data types, operations with them; control flow - if conditions, for and while loops; running the tests in Python! Then comes Selenium - locating element, waiting for them to appear, reading text and attributes from the HTML elements! 

Finally, we combine everything into a small program! 

- For each module, there are links and instructions for preparation. It is best to read all of these before the workshop;

- Instructor will explain the theory from the preparation section and focus on writing programs to solidify the knowledge; 

- If you don’t complete the tasks on time for the given module you lose 1 life;

Golang 101

WHAT IS IT ABOUT? 

There are so many programming languages out there, and new ones are popping up almost every day. Which one to choose? Where to start? To stay ahead of the game by broadening your skillset, learning a new language is important for your professional growth. Some of the developers claim that Golang is a neat combination of the best features of the most popular languages. 

You will have the chance to find this out yourself at this workshop. Join us at the Golang 101 workshop. We’ll get familiar with Go - a modern language that makes it easy to build simple, reliable, and efficient software. We’ll build a real-world application and learn the basics of programming in Go. 

Golang is also known as Google Go, which is the programming language created by (as you may have already guessed) Google. Golang was initially developed at Google in the year 2007. 

YOU’LL NEED TO HAVE: A laptop and a charger Go installed (follow https://golang.org/doc/install). If you’re having issues, it’s ok, you can come before the workshop and we’ll help you. 

WHAT WILL I LEARN DURING THE WORKSHOP? 

You will be introduced to Golang and will learn the basics of this programming language together with experienced professionals from the Uber Engineering Sofia team. Moreover, you will meet like-minded people from the tech field. 

WHO IS IT FOR? 

The workshop is for people who are passionate about coding and have some programming experience but are new to Golang.

The Groundhog Development Method

I guess many of you are young enough to have never heard of the "Groundhog Day" movie (released way back in 1993), which serves as the inspiration for this talk's title. Without ruining the great movie for you I'll tell you it's about a man whose life is stuck in a loop, and unless he changes something his life is not going anywhere.

Does this story remind you of something else? A lot of software projects are also stuck in a loop - starting strong, quickly drowning in complexity, eventually discarded and replaced by projects which ultimately suffer a similar fate. You've seen this happen many times, right? 

In this talk we'll discuss what exactly is wrong, how did we end up in this mess, and what should change to break that vicious cycle. And maybe we'll have a bit of fun while doing so!

Success Hacking 101: How to Survive the Commoditization of Your Job

Tech and tech talent are becoming commoditized. This is happening within organizations and within teams. Although tech hiring is still tight, globalization, automation, AI, Cloud, skill shift, and other tectonic movements are changing the tide. What used to be irreplaceable tech and tech talent can now be bought on the open market and substituted for what is already in place. For software engineers, this means our tech skills are increasingly replaceable, which means we are increasingly replaceable. It may be hard to believe when software engineers are in high demand and our wages are skyrocketing, but the writing is on the wall: Software engineers need much more than just tech skills to survive and add real value to today’s teams and organizations. Come find out what skills you should be learning and practising to stand out in the software engineering crowd, be irreplaceable and invaluable to organizations and teams, and succeed in life.

The Useless Leader is the Best Leader!

Command & Control is still the predominant leadership style in the software industry, except maybe in the most successful super-growth organisations. The talk explores why is there a trend and what we can learn from the successes of existing and past Unicorns when it comes to building and leading a high quality engineering team. I claim leaders should “serve” instead of “command” - act as enabler to all the smart people in their teams and exploit the power of the “subject matter experts” by empowering them with making decisions and owning the delivery. My engineers and managers do not work for me. I work for them - they are the “boss”. That works great for me, for my engineering team and for the organisation. The talk aims at sharing how and why that works, what are the problems that it imposes and how to mitigate or solve them.

SOLID principles - {part 1 of 5} - "S" the most misunderstood principle

In object-oriented computer programming, SOLID is a mnemonic acronym for five design principles intended to make software designs more understandable, flexible and maintainable. “Single purpose” sounds self explanatory and developers usually assume they understand it and move on towards the other principles. In this talk I am going to take them back few steps and explain what stands behind this principle and how to apply it to multiple levels of the application architecture.

Does functional programming actually help in production?

The presence and adoption of functional programming concepts in mainstream languages has continuously become more prevalent within the last few years. This leads one to believe, that the things this paradigm has to provide are apparently, in some way, beneficial. Now two questions arise. To what extent is it beneficial and how do these things actually make a difference in my production application? In this talk I’d like to travel across the planes of functional programming and show you how this paradigm helped us, what concepts made a difference and how it may generally, probably, be able to help others.

The click that will bring your weekend back

Working with both startups and enterprises, over the years I noticed that many of the companies have challenges setting up strong release practices. That results with risky, error-prone releases followed up with a lot of bugs which cost them a lot of resources.

With this talk, I am aiming to inspire people to step back from the day to day operations and think about how setting up a fully automated process is going to benefit the companies they are working with and at the same time get their weekends back. I will talk about optimizing the release process on different levels in the organization, as well as leveling up the quality of the technology. I will also introduce some tools and techniques to the audience that helped us create a steady pipeline.

The talk is perfect for tech leads, CTOs, or software engineers who are looking forward to bringing improvement in their organizations.

We will discuss Donut cache, Memory cache, Redis, Varnish, CDNs, and many more. We will dive into demos of real-world 

implementations which can cause unpredictable problems. Some of these are horrible, and some are face-palm. At the end of this presentation, you will be aware of the different trade-offs with each caching methodology, and which might best for your situation.

Hardware connectivity on the progressive web

The browsers can actually take control of physical devices in the real world like lightbulbs, robots, printers, NFC tags, toys, and even drones by providing new web standard hardware connectivity APIs such as WebBluetooth, WebUSB, WebNFC and etc. 

On the other hand, Progressive web apps open a new era to build a web application that works offline and resemble a native application. Hence, every day we are getting closer to run web apps only on browsers that don’t need to be installed from any app store and it will take control of hardware around us.

Introduction to Machine Learning

Machine Learning / Deep Learning is where all the hype is. From automation to self-driving cars, there are a lot of applications. To be effective in it, you need to combine various skills – engineering, statistics and programming. 

This talk will aim to do three things: (1) sketch the lay of the land in the world of ML, (2) give an overview of the most popular tools and (3) sketch the next steps if you're considering specializing in it.

 By the end of it, you should walk away with a basic understanding of what machine learning is and how to start learning and applying it.

SOLID principles - {part 1 of 5} - "S" the most misunderstood principle

In object-oriented computer programming, SOLID is a mnemonic acronym for five design principles intended to make software designs more understandable, flexible and maintainable. “Single purpose” sounds self explanatory and developers usually assume they understand it and move on towards the other principles. In his talk Martin Chaov is going to take them back few steps and explain what stands behind this principle and how to apply it to multiple levels of the application architecture.

Cache me outside - Caching Methodologies and Architectures


Caching can be your best-friend or your worst best-friend. A poor cache implementation can mean the difference between experiencing blazing fast performance or unexplained random slowness, or both! It can even result in random stale (out of date) content which you can’t explain.

In this presentation we will demo and compare different caching methodologies, and their perceived real world uses. We will discuss Donut cache, Memory cache, Redis, Varnish, CDNs, and many more. We will dive into demos of real world implementations which can cause unpredictable problems. Some of these are horrible, and some are face-palm.

At the end of this presentation you will be aware of the different trade-offs with each caching methodology, and which might best for your situation.

Workshop:

Learn Python & Selenium the fast way

This workshop will teach the basics of Python: functions, common data types, operations with them; control flow - if conditions, for and while loops; running the tests in Python! Then comes Selenium - locating element, waiting for them to appear, reading text and attributes from the HTML elements! 

Finally, we combine everything into a small program! 

- For each module, there are links and instructions for preparation. It is best to read all of these before the workshop;

- An instructor will explain the theory from the preparation section and focus on writing programs to solidify the knowledge; 

- If you don’t complete the tasks on time for the given module you lose 1 life; 

- When all of your 3 lives are lost it is GAME OVER!
