Developing Software and IT systems

164 posts

Coding and advice in developing Software and IT systems.  At all levels of complexity. Special care has been taken for beginners and students.  Both code and advice, are a product of 25+ years of active commercial programming, team leading and delivering systems architecture.

Here you will also find a lot of very deep, commercial C++, JavaScript, and jQuery. The focus of the material presented, is on how to deliver APIs and libraries that are rock solid and useful. And that does not annoy the end-users, at the same time.

By no means do not hesitate to leave comments.  info@dbj.systems

C Sharp implicit casting

February 13th, 2008

There might be something very interesting for you in FM#. Maybe a interesting example of the usage, of C# implicit casting operator? … Wait, what is FM#?

FM# is (my) C# library of Foundation Mechanisms (aka FM).

For a start, let me offer some magic. Lets look in the method cast() of the util class.  This method is used to get the value from the xml node, and cast it implicitly, to the C# variable of the same type. Reminder: value of the xml node is always an string.  Confusing. Let’s just use this then. Here is the method footprint:

And ADO.NET 3.5 said: Destiny of the distant object is not my destiny.

Apparently url http://astoria.mslivelabs.com does not exist any more. This is where Project “Astoria” liveth. What happened next, is explained (also) in this presentation. Although terminology is somewhat confused or plain wrong but nevertheless a lot of useful hands-on information is delivered.

Just finished visitation of ADO.NET 3.5 site , aka Project “Astoria”.
It looks simple and pretty REST-full. And this is the BIG DEAL about it apparently.

It is based on the REST concepts. There is no SOAP in view. No WS-*, etc.

None of the key concepts Microsoft at large, and “his” blog-happy uber-developers have been trumpeting into our ears for last few years. And very loudly so with that. Now comes “ASTORIA” and the REST. All change!

Do your C++ reality check…

[April 19th, 2006]

Recently while having some discussions on a forum populated with very good C++ developers, I started to realise …

Many of them do not see the reality same as I do? Most of the discussions are simply because of reality checks that developers have to do all the time. Especailly if they are in this IT industry where constant change is the name of the game.

Simple example : STL. Discusion exploded arround the issue of using or not using the STL in the code? A drastic example of an reality check missing. Here is why:

  1. STL does not exist any more. At least two years.
  2. STL is replaced with stdlib : standard library for C++
  3. Standard C++ has stdlib at its core. It is based on stdlib.

Three points from the reality of C++ today. Have you done your C++ reality check, yet :) ?
