Tips, tricks and quirks in .NET

.NET is a powerful and flexible platform with many mechanisms that can significantly increase productivity. A limited
understanding of its details, however, can prove to be fraught with consequences. During my work, I have seen many situations
where something did not work as expected. It turned out. that the information on blogs or courses was 99% correct, and I
was hitting that forgotten 1%. On this presentation a few such cases.
I will also debunk few really popular interview questions which we used to answer wrong.

Passwordless Web 1.5

You've been using passwords forever. In fact, you've never liked them. As a user, you had no choice, and as a developer, you had no real alternatives. Until now.

In this session, we will explore the evolution of digital security, highlighting the significant drawbacks of passwords, such as susceptibility to breaches, phishing, and poor user experience. I will introduce passkeys, explaining how they leverage public key cryptography to provide a more secure and user-friendly authentication method. I will also discuss the technical underpinnings of implementation.

Migration to nowhere

Cloud is amazing. It's fast, reliable and flexible. Starting brand new application in cloud is incredible easy.
But moving existing solution to cloud...
...well that's a different story.
Many consultants say that it's easy - first lift and shift and then go cloud native. I wish it was so simple.
In this talk I will share my experience from few migration projects. Believe me - this won't be happy story. Because changing everything without breaking anything is hard.
This will be story full of "I wish I knew back then..." so you don't fall into same traps as me.

Fundamental web-security flaws

On prepared website we will jointly look for simple vulnerabilities left by 'novice' programmers, e.g. SQL injections, incorrect of backend validation of forms, listing of folder contents, broken access control and many others.

Speaker's toolbox

Delivering an effective speech or presentation requires more than just a great topic and amazing speaking skills. Professional speakers use a variety of tools and software to improve their presentations and engage their audiences.
In this presentation, I will introduce you to my toolbox and offer tips how I used it effectively.

Unboxing Deno

New framework from the creator of Node.js was supposed to be faster, more secure and more convenient to use on a daily basis than its predecessor.
How many of these promises have been kept? What is the status of the project? What are the strengths and weaknesses? Will it find its place on the JavaScript backend, where Node.js has reigned for years?
And the most important: is Deno really ready for production?

Small things we got wrong in .NET

.NET is a powerful and flexible platform with many mechanisms and paradigms that can greatly improve productivity.
Having a limited understanding of its details can backfire. During my work I have seen multiple situations when something works not the way it was expected. It turned out that information in blogs or courses was correct in 99% and I came across this forgotten 1%
In this talk I will show few such cases.

Passwordless Web

You have a password for your phone, computer, mail, facebook, github, linkedin, bank ... and a hundred other sites.
Are they all complicated, unique and do you change them regularly? Do your app users do in the same way?
Or would it be better to get rid of passwords once and for all?
It's quite simple, sit back for a moment and listen to how to do it.

Data-Driven Governance

Big (red) Brother is watching You!
Only in China so far, but it's not clear what the future will bring.

For many years Chinese government has been implementing tools and algorithms to evaluate citizens.
A lot of myths have grown up around this venture. Some say it is the beginning of the Orwellian world of full control, others say it is the answer to the growing needs of the moment.
During the presentation we will take a closer look at this one of the biggest data science projects in history.

Inconvenient truth about passwords

Passwords are one element of our digital security. There are a lot of myths and lies about them, meanwhile a lot of seamingly good pieces of advice is outdated.
In this presentation, I will talk how the world of passwords looks like in 2023. What the rules for creating and managing them should be. How to embrace hundreds of passwords and not go crazy. Why passwords leak and how to limit the damage from leaks.

Secret Life of Algorithms

Have you ever wondered why your search results are as you see them?
How are the recommended Facebook entries selected?
What really determines your credit decision?
Computers, programs and algorithms surround us. They make our lives easier, but at what price?
During my presentation I will present few algorithms which control our life. I will show examples, how our sensitive data can be used against us.

Where is my mind?

Open website, read the headings, run your eyes over the paragraphs, click on the link.
Go to a new website and start again. In the meantime, check Facebook, Twitter, email.
Quickly get bored and grab your phone.
Forget what you really wanted to do.
Concentrating on one activity comes harder and harder, and reading a book with understanding becomes a challenge.

This is how the internet is messing our brains.
In this presentation, I will talk about the mechanisms and effects of brain changes.

How to train Junior developers

The IT industry has never been as open as it is now: we hire students, people after courses, 'non-technical' people.
In this speech I'll present how to efficiently introduce a Junior to the realities of professional software development. I'll show an approach that helped me to effectively utilise the skills of a new developer with reasonable engagement of the rest of the team.

How to handle mature projects

Job adverts mammoth us with buzzwords, benefits and a pay-spread. The sad truth is that you won't see Blockchain, DDD or CQRS in your next project.
Unfortunately, we spend most of our careers maintaining or developing existing projects. During the presentation, I will share a list of actions you may take when entering a project so as to avoid the pitfalls of unknown.

Let's get more functional

- Functional programming is difficult.
- It is impossible to program functionally in an object-oriented language.
- I won't get any benefit from functional programming
I have heard this many times, you probably have too.
In this presentation I will show that this is not true. If you can program object-oriented in C# then you can also do it functionally. You don't need F# for that.
