From a StackOverflow question about a freezing Delphi application, I posted some experiment-based debugging tricks.
May help any developer in his/her fight against random bugs...

Synopse SQLite3/mORMot framework 1.15
2011-09-25. Open Source › mORMot Framework
Our Client-Server ORM framework is now available in revision 1.15.
This is a major upgrade of the framework:
- It is now called mORMot -
so please update your T-Shirts or coffee cups
- It is able to use any Database engine back-end - in fact, it is SQLite3 powered, not SQLite3 limited;
- In particular, direct OleDB and native Oracle have been implemented;
- It makes use of the genuine SQlite3 Virtual Table mechanism everywhere to allow mixed access to any database engine;
- New
TModTime / TCreateTimekind of fields; - Enhanced stability, speed and multi-thread implementation;
- Methods and functions have been enhanced, according to user feedback (thanks you all for your interest and forum posts!);
- Extended documentation (more than 700 pdf pages), with new diagrams and a lot of new content;
- New associated tools, like LogViewer or SynDBExplorer;
- The SQLite3 core can now be used without our ORM - it has been updated to the latest 3.7.8 version;
- Open Source (under GPL/LGPL/MPL license), running from Delphi 6 up to XE2.
Some thoughts about OSX integration in XE2
2011-09-25. Pascal Programming
You know all that one of the most exciting features of Delphi XE2 is the
MaxOSX Cross-Platform feature.
You've got the UI part,
that is FireMonkey, but underneath, you did have some RTL modifications in
order to let our Windows-centric solutions be OSX ready.
The first main step was to make our code speak with the "Objective-C" way of coding.
Objective-C is the primary language used for Apple's Cocoa API, and it was originally the main language on NeXT's NeXTSTEP OS. It's some object-oriented C variant, but something other than C++ or Java. In fact, Objective-C sounds more like a SmallTalk variance of C than another C++/Java/C# flavor. For instance, the Objective-C model of object-oriented programming is based on message passing to object instances: this is just another way of doing it. It has some advantages, and disadvantages (I don't want to troll here) - but it is definitively nice. And the memory model is just something else, more close to our reference-counting way (as in Delphi interface implementation) than a garbage collector.
Synopse SQLite3 framework is now mORMot
2011-09-25. Open Source › mORMot Framework
In case you were redirected from the previous "Synopse SQLite3 framework" category link, here is the new thread to be used instead: http://blog.synopse.info/category/Open-Source-Projects/mORMot-Framework Since revision 1.15 of the framework, it is able to connect to any database engine […]
Synopse PDF Engine 1.15
2011-09-25. Open Source › Synopse PDF engine
For our PDF generation Open-Source library, this is a small fix update.
It can now be compiled under Delphi XE2.
But it's still working from all previous IDE versions, starting with Delphi 5,
and still 100% free - released under GPL/LGPL/MPL license, choice is yours.

L10n and i18n in our framework
2011-09-14. Open Source › mORMot Framework
In computing, internationalization and localization (also spelled internationalisation and localisation) are means of adapting computer software to different languages, regional differences and technical requirements of a target market:
- Internationalization (i18n) is the process of designing a software application so that it can be adapted to various languages;
- Localization (L10n) is the process of adapting internationalized software for a specific region or language by adding locale-specific components and translating text, e.g. for dates display.
Our framework handle both features, via the SQLite3i18n.pas
unit. For instance, resourcestring defined in the source code are
retrieved from the executable and can be translated on the fly. The unit
extends this to visual forms, and even captions generated from RTTI.
In short, making your software open to any language is handled by the framework, from the bottom-up.

Using Extended in Delphi XE2 64 bit
2011-09-12. Pascal Programming
Unfortunately, Delphi's 64-bit compiler (dcc64) and RTL do not support
80-bit extended floating point values on Win64, but silently alias
Extended = Double on Win64.
There are situations, however, where this is clearly undesirable, e.g. if
the additional precision gained from Extended is required.
The Open-source uTExtendedX87 unit provides a
replacement FPU-backed 80-bit Extended floating point type
(TExtendedX87) for Win64.

DataSnap-like Client-Server JSON RESTful Services in Delphi 6-XE5
2011-09-01. Open Source › mORMot Framework
Article update:
The server side call back signature changed since this article was first
published in 2010.
Please refer to the documentation or this forum article and
associated commit.
The article was totally rewritten to reflect the enhancements.
And do not forget to see mORMot's interface-based
services!
Note that the main difference with previous implementation is the
signature of the service implementation event, which should be now
exactly:
procedure
MyService(Ctxt:
TSQLRestServerURIContext);
(note that there is one unique class parameter, with no
var specifier)
Please update your code if you are using method-based
services!
You certainly knows about the new DataSnap Client-Server features, based on
JSON, introduced in Delphi 2010.

… plications
We added such communication in our mORmot Framework, in a KISS (i.e. simple) way: no expert, no new unit or new class. Just add a published method Server-side, then use easy functions about JSON or URL-parameters to get the request encoded and decoded as expected, on Client-side.
