It was so much fun to create one of the "Developer Skills Sprint" sessions last week. During the live Q'n'A session I have promised to make the source code of my DataSnap "Simple Calculator" REST server and client projects available. Here it is! It is now available from the Code Central at http://cc.embarcadero.com/item/29915 A few years ago, back in the Delphi XE time frame, I have created a series of DataSnap "Delphi Labs". The source code of these Delphi Labs has been updated to Delphi...

I'm back from the RAD Studio XE5 in LIVE! event in Bratislava, the capital of Slovakia. It is not the first time I have demonstrated true native, multi device development for Android, iOS, Mac and Windows with Delphi XE5, but it always feels refreshing. Delphi XE5 release is so special, because you can reuse your existing Delphi programming skills and existing codebase and be immediately productive on all major desktop and mobile operating systems in the world! Programmers in Bratislava not o...

During my CodeRage 8 "Secure DataSnap Development" session I'm demonstrating different levels of security in DataSnap architecture. Communication Protocol: DataSnap supports three different communication protocols: TCP/IP, HTTP, HTTPS. Choosing the HTTPS protocol that is implemented using SSL (“Secure Sockets Layer”) adds encryption to the communication between client and server, making it a secure solution. Two other protocols – TCP/IP and HTTP – are inherently not safe and such a commun...

The CodeRage Mobile conference Day 1st is almost finished. I'm listening to last sessions from Anders Ohlsson. Few hours ago I have been doing my own session "Create iOS Applications that Work with Enterprise Web Services and Multi-tier Architectures" and promised to share the source code from my demos. I have uploaded it to Embarcadero Code Central. Simple DataSnap database server and iOS client Email validation SOAP web service and iOS client Enjoy!...

It seems that it is my very first post in the New Year 2013, so I wish You all the best and great time writing all kinds of programs. I'm sure it is going to be a great year for Delphi and Marco is predicting it as well, especially that next month Delphi is going to become adult! Two years ago I have put together a serie of Delphi DataSnap tutorials called "Delphi Labs" and many people found it useful, so I thought that it is a high time to at least update code samples for every tutorial so t...

Blog is very much like a "log". Place to make a note of something that heppened. I like to document here different events that I'm presenting on or at least participating in. Programming events I mean... The more events there is and the more frequent they get, it is more and more difficult to do it in a timely fashion. Today we have done with Stephen and Jon the last Developer Direct live webinar and I have realised that I have not been documenting my live events in the last month or so! The...

The C++ CodeRage 7 virtual conference is great fun so far. Lots of great sessions and we had a great guest on Monday: Bjarne Stroustrup, who invented the C++ Programming language. Right now in the virtual space there is my pre-recorded "Building scalable, multitier systems with DataSnap and C++Builder XE3" is happening and I'm getting ready for the live Q&A session. In the meantime I have uploaded slides and source code for the demos presented to Embarcadero CodeCentral. There are two ...

The CodeRage7 online Delphi developer conference is in full swing! There is plenty of great content and I'm looking forward to replies of some sessions as it is impossible to follow all of them! To me the biggest news is to have Marco Cantù appointed as the new Delphi Product Manager! Welcome to The Team! In a moment my "Building Scalable Multitier Systems with DataSnap XE3" starts. It is prerecorded and I have promised to put the link to source code of all demos presented on my blog, whic...

The history is happening right now, right here! I'm just back from Bucharest, the capital of Romania. Yesterday it was a pure pleasure to present "RAD Studio XE2 in Action LIVE!" to the crowd of enthusiastic developers. It looks it was the first Delphi/C++Builder event ever in Romania! The audience was very technical and positive. There was no end to questions about Delphi, C++Builder, FireMonkey, future plans for RAD Studio and many other, sometimes very low-level. The event was divid...
