Jest bug! 😦 Hacki się mszczą, ale teraz musimy dostarczyć paczkę Kolejny tydzień, kolejny ten sam bug Bądź EXPLICIT

When we started PlatformX project, we were using full .NET Framework. Then we migrated to .NET Core. Despite many advantages this migration meant a problem with using Roslyn. This problem is called MsBuildWorkspace...

Git is simple but different – it is probably the most popular version control system (vcs) used in it projects around the world. It is also very often misused because although it is very similar to other vcss at the api level, it is very different underneath. Let’s take a look at the nuts and bolts of git to understand it better and, as a result, to use it properly and effectively.

For some time now I am working quite heavily on AWS in my current project. And of course we try and give our systems the shape of micro services (who wouldn't?). When using micro services architecture it is very often a good practice to not use a single database to which every single service is connecting whenever it needs data. Instead it is recommended to give every service which uses data its own database to store its model. AWS give us a very interesting NoSql database named DynamoDb which purpose is...

This post shows how RethinkDB changefeed can be exposed from ASP.NET Core with Server-Sent Events and WebSockets fallback.

This week we had serious case of "how come it doesn't work on production? It did work on my laptop". After the release one core function did not work. Not in a sense that it threw exception. More like it didn't apply the changes it was suppose to. We opened the code, we looked at it and we scratched or heads wondering "what the hell is going on?!". This specific method that was responsible for the work even had good unit tests that were finishing successfully. We eventually found the cause of the issue a...

I think its no secret that more and more development teams are trying to take more of a micro service oriented approach (and for all the good reasons). With the power that cloud providers give plus the benefit of container (Docker and Kubernetes) I think it is inevitable that micro services will become a standard. Of course this approach is not problem proof but it allows us to move some of the monolith type application issues somewhere else where we have more flexibility

Człowiek w ciągu miesiąca powinien przespać około 160 godzin, drugie tyle pracować, a 20 godzin poświęcić na delektowanie się kakałkiem. Na hobby nie zostaje wiele czasu. Chyba, że tak jak ja jesteście zajarani swoją pracą i na myśl o konferencjach programistycznych czujecie przyjemne mrowienie w okolicach karku. Rzadko kiedy zdarza się dla mnie tak obłożony miesiąc jak miniony kwiecień: 4 konferencje, 1 warsztat, czyli 6 dni poświęconych na eventy programistyczne. Uczestniczyłem w serii wykładów, lizną...

There are many programming-related things, I have tried at least once in my life such as web development, desktop development, cloud computing, functional programming, distributed computing, artificial intelligence, IoT, page styling with CSS (sic!) and many others. However, there’s one popular programming area I’ve never tried and I think I’ve been always scared of – mobile development. There are several reasons for that:I’m not a smartp...

Dziś na tapetę wrzucam temat wycen szacunkowych i wycen wiążących – jeśli rozliczasz się projektowo, na pewno spotkałeś się z tymi pojęciami. W wpisie poruszam m.in. kwestię tego jaka rozbieżność jest “smaczna” pomiędzy wyceną poglądową a finalną. Jak to działa? Zazwyczaj dostajemy brief od klienta, na podstawie, którego dokonujemy szacunkowej wyceny. Klientowi jest to zazwyczaj potrzebne do wybrania wykonawcy, lub pod...
