Introduction Some days ago, Embarcadero has presented the new version of RAD Studio, 2010. The are many new features, but you can find in a lot places around the web, so I won’t repeat them here. One of the things widely requested from all Delphi programmers all over the world over the past few years, including myself, is

Yes, this is a nice news! My AMQP Delphi wrapper for 0MQ is officially included into the distribution of 0MQ. Now sources are managed into the main svn trunk. You can read the news in the project’s main page. You can see the code here. In the upcoming greatest Delphi conference ITDevCon, I’ll have a talk about MoM (Message oriented middleware) and I’ll talk about ZeroMQ too.

The Advanced Message Queuing Protocol (AMQP) is an open standard [application layer] protocol for [[Message Oriented Middleware]](http://en.wikipedia.org/wiki/Message_oriented_middleware “What does it mean “Mom” ?”) (MoM). The defining features of AMQP are message orientation, queuing, routing (including point-to-point and publish-and-subscribe), reliability and security^.^ The good news about AMQP is that AMQP mandates the behaviour of the messaging provider and client to the extent that implementations from different vendors are truly interoperable, in the same way as SMTP, HTTP, FTP, etc.

When I was at Delphi Live in San Jose, I attended Marco Cantù and Cary Jensen Masterclass about Delphi Multithreading. Although, I’m expert of multi threading techiques and the related problems, this masterclass was very interesting and well organized as well. IMHO, the topics have been presented in very effective manner and, as usual, in a very professional way.

This year I cannot miss the DelphiLive! event! I’m still in Rome, but in a few hours I’ll leave Rome with a fly to Frankfurt. Then I’ll take a fly for San Francisco. I’ll be in San Jose in the evening (local time). You will be at DelphiLive! ? See you there!

Many users asked Embarcadero to include a profiler in the next Delphi for Win32. Waiting for this, there are some interesting tools for profile a Delphi program. For example, AsmProfile is an Open Source sampling profiler wich is very simple to use. UPDATE: Actually AsmProfile is an “Instrumenting” profiler. It uses runtime function detouring and assembly to profile any selected function.

As GUI framework such as VCL become more and more powerful, it’s common practice to let the UI layer do more than it should. Without a clear separation of responsibilities, the UI layer can often become an integral part of application and businness logic, but… this kind of responsabilities belongs to other layers of the application.
