Great success for RAD Studio in one of the most important italian government palaces

This week, in one of the most important government palaces in Italy (I cannot say which one), I did a consultancy about mobile development. The internal dev team is currently using Xamarin and they have a blocking problem with it. In the team there is a friend of mine which called me some days ago to know if I know how to solve their problem using Delphi. I told him that the “blocking” problem could be solved with Delphi. The resultant 2 days of consultancy were been quite hard, but the result has been really rewarding. A long standing problem has been elegantely solved using Delphi in a couple of hours.

The problem was about using HTTP client certificates with iOS in a Microsoft architecture, where each user had its own certificate.

I dont know Xamarine so deeply to say if the problem could be elegantly resolved with it as well, but the team is quite smart and skilled, so I think that they have been tried all the documented solutions to face the problem, but without success.

I want to thank the always helpful Jim McKeeth and the great Diego Navarro from Embarcadero, to have help me about this issue. Thank you guys.

 

Mar., 22nd 2016: “Refactoring legacy code to design patterns”

On Mar,22nd 2016 I’ll talk about refactoring during a programmed skill sprint with the title: Refactoring legacy code to design patterns.

After a short theoretical introduction, there will be a live demo showing the power of refactoring and the power of the refactoring engine built in into the RAD Studio IDE. At the end of the session will be given some reference to the most important books about refactoring (IMHO).

DataSnap Filters Compendium Updated to Delphi 10 Seattle

Very quick info.

Not tremendous useful today as when developed (Delphi 2010 time frame) but, if someone is still using my DataSnap Filters Compendium (and I know some users heavily use it), now can find the Delphi 10 Seattle version on github. Currently works all the speed test and the server/client test. Consider this as a very stable beta.

Here’s the project repository

Echoes From The Past: Message Master For Delphi a.k.a. MM4D

Some years ago, at the Delphi 6/7 timeframe I was working on a client/server program with c.a. 400 forms and 200 units. At that time I needed a simple way to localize in Italian (in primis) and in other languages, all the  standard dialogs (ShowMessage, InputBox, InputQuery etc.). Moreover, I would have liked to give a unique style to them. In addition, I needed to localize that dialogs. Moreover I needed a simple way to show a program of a background operation using a not modal dialog with a simple pattern like the following:

  ...
  ShowStatusPos(STATUS_CAPTION, Point(50, 50), True);
  try
    for i := 1 to 100 do
    begin
      SetupQuery(LMyDataset, i);
      LMyDataset.Open;
      while not LMyDataset.Eof do
      begin
        //do something
        UpdateStatus(i, Format(STATUS_CAPTION + ' %2d%%', [i]));
        LMyDataset.Next;
      end;
      LMyDataset.Close;
    end;
  finally
    CloseStatus;
  end;
  ...

So, after some tests I wrote Message Master for Delphi. MM4D is a smal library which supports all of these features, or at least these features were supported at that time. Indeed, since then I saw many (really many) 3rd-party Delphi/C++Builder written programs which actually use MM4D. However, since then I didn’t supported that library anymore. Now, more or less, 15 years after, a user wrote to my about MM4D support in Delphi 10 Seattle. So, I decided to update the code to let it compile on Delphi 10 Seattle. So, now it is currently supported (even if I dont plan to improve it in any way in the short term). However if someone use it or want to use it and update/upgrade/improve, here’s the github reporitories. I hope I have done something good for all the old time users.

In the repositories there is a demo to show all the features of MM4D and there is also a small tool called UnitsAdded.exe which can be used to add the MM4D features to a project automatically (search for Dialogs.pas and, if exists, add MessDlgs after it).
MM4Delphi uses the good XiControls (included). So, still thank you to Eugene Genev for his XiControls.

DelphiMVCFramework at the 10° Delphi Meetup in Dresden , Germany

Mathias Pannier did a nice talk at the 10° Delphi Meetup in Dresden, Germany. You can find his review with the slide (both in english) in his blog.

Mathias contacted me about some specific questions the audience did.

Here’s my replies.

  • Is it possible to have a [MapperJSONSer(‘first_name’)] attribute for DataSet fields?
    • Not currently. It quite simple to implement but now this feature is available only for objects using RTTI attributes. Maybe in the near future this will be extended also to dataset serialition.
  • Is it possible to implement a custom renderer for example for xml output?
    • Sure! DMVCFramework is really opened to extensions. You can implement renders for every format you like, you are not tied to the built in.
  • Which Delphi edition is required? Starter, Professional, Enterprise, Ultimate?
    • DMVCFramework requires Professional version, because WebBroker is available from that version upwards.
  • Did You have any performance comparison?
    • Yes, it is not a complete test, is just a rough test between DMVCFramework and nodejs. DMVCFramework is not running into Apache or IIS, but is using its INDY default web server so the actual performance using a real webserver are far better.

dmvcframework_nodejs_preliminary_test

I’m planning to do more tests and as sson I’ll do them, will be published here and in the facebook group.

  • What about documentation?
    • The framework is quite intuitive, so after read this presentation (ITDevCon2013) you can go though all the samples (which covers all the features) and you will be up&running in in an hour or so.
    • However, some volenterous users, are starting to work on a more structured documentation. There will be a markdown generated site which will provide tutorial and devguide.

 

Still thank you to all the people which actively partecipating in this project.

 

Stay tuned.

 

 

Delphi Cookbook 2nd edition has been announced

Just after 1 year and half from the 1st edition, the 2nd edition of Delphi Cookbook has been announced. The first edition got a lot of interest and appreciation comments, so the editor decided to ask me a 2nd edition. So here it is! It is still in work-in-progress but the work is going smooth. In a month or two will start the review phase and then the book should be officially presented.

However, if you are interested, the book is already available in preorder.

I want to thank you all for the success which Delphi Cookbook gets, and I hope that this 2nd edition will gets the same (or, why not, better) appreciation.

Stay tuned

Migration to github for all my open source projects… done!

Since when Google announced that Google Code will be closed I did start to plan the migration of all my open source projects. Now, the migration is terminated.

In the next days, I’ll add all the contributors too, so that the development can go forward as usual.

These are the projects

  • DelphiMVCFramework
    • if you are reading my Delphi Cookbook, please use this new repository instead of the old SVN one, reported in the book.
  • DORM, the Delphi ORM
  • DelphiRedisClient
  • DelphiDIContainer
  • DelphiSTOMPClient

All the repositories are available on my personal github page https://github.com/danieleteti and, as usual all contributions are welcome.

Enjoy.

 

DelphiPodcastIT episode 2 – Interview about DelphiMVCFramework

DelphiPodcastIT
DelphiPodcastIT and DelphiMVCFramework

In the 2nd episode of DelphiPodcastIT (Delphi podcast in italian language by Marco Breveglieri) there is a my interview about the past, the present and the future of DelphiMVCFramework with a lot of technical contents. The interview itself is quite long, just like a micro training on DelphiMVCFramework.

Enjoy the listening (only in italian, sorry)
