Have you ever dreamed of writing c#/java/any-language-of-choice code for the client-side development? Sharing client and server code classes? No plugins and transpilation to JavaScript? “Write once, run everywhere” said Sun Microsystems promoting Java in order to inspire people to use it. While being a nice promise and actually pretty inspiring, somehow it doesn’t make people really believe in it as of today. The world appeared to be more complex than that, especially in the mobile world. Reusa...

Each time I think about the problem with feedback, I recall the famous presentation of Erik Meijer “One hacker way“, when he says about the system developed without a proper feedback – no feedback loop – summed up with a sentence “That’s how Microsoft Office Ribbon was born”. I think I can see this Microsoft-Ribbon problem everywhere, not only at work but also in life. People tend to underestimate how much is it important to give, but also to receive feedback properly. It might also be that they...

I have met and talked to a lot of developers in my life. I went through the whole lifecycle of software production many times. People have changed, but the projects that have been implemented, are happily still running in production (at least most of them, let’s say :)). What I have noticed during this period of over 10 years working with the software and people producing it, is that many developers have quite a strange approach to work. In IT there’s this request type called “Fire and forget”, ...

A few weeks ago,  on my way to the .NET Developer Days conference, I had a thought that I must be getting old. That’s because the only book I took with myself was about parenting 🙂 Before, usually, it was something really technical that I don’t have time for and somehow I plan to catch up on the train or in the hotel. I had an interesting conclusion for the first time in my life, that actually putting the hard work to become a better parent, all the lessons learned through the period of raisin...

Code Europe – About the Conference The last conference I’m going to attend this year will be Code Europe. The event will take place on 13th of December 2017 in the Congress Center of Centennial Hall in Wrocław. I will attend the conference in Wrocław where I’m living, so the agenda will be from this perspective. The conference takes also place in Kraków and Warsaw on the other dates, but I won’t be writing about it. Organizers claim that it is the biggest programming conference in Poland, which ...

/ Kuba Do you consider yourself a successful person? Think about it for a while… How do you measure it? What is it that drives you? What are your core values? I have always been a big fan of self-awareness and conscious life. I think life is too short to spend it unconsciously following some other people without actually having time to think about ourselves. In the day-to-day communication, what is shocking me always, what I cannot get used to, is that people generally don’t care. We’re living in the...

Dreaming of being a technical manager Many people when beginning their adventure with programming, do share a vision of becoming a manager in the future. Some of them more technical, than the others. Of course there are also those who do not even consider it. Code is their life – respect. I always belonged to the first ones. I’ve never really wanted to abandon the programming forever. Manager but technical! You could see that with the eyes of your mind, THAT guy, THE master, sitting there and dealing ...

My application for the competition Daj się poznać 2017 will be using a Web API on the server side, to feed the Angular client app with the data. Today, I want to discuss one very simple, but also very important topic for the APIs accessed over HTTP.HTTP Status Codes The reason we will build Web API, is to have a fully standardized service, which will be able to query our database and provide the resources to the customer. Whoever we call a customer. In our case, it will be an Angular app, living in the...

Imagine that you have a service, which receives requests to execute specific methods, possibly from a number of different underlying libraries that you don’t want to expose directly. Possible examples are web services. The request comes in as a number of string values (method name, parameters etc.) and you need to respond with results. So you have inherited a project with API that starts with a method: object Invoke(string methodName, object[] parameters); You now have to call variety o...

Authentication The topic looks obviously obvious and generally speaking standard user doesn’t care much about the details. He wants to register, login, and make sure that his password is safe. The more you read and learn, the more sophisticated requirements you have for protection, state management on the server and client side, the more things are getting complicated. The problem with authentication is basically about: how does one prove that he is the guy that he’s pretending to be? In the world of w...
