ISA is about the 5th computing era : The Distribution one.
When the things are done in many computing units, of many kinds, in many places, available to anyone. When the centralization is no more possible.
The purpose of this blog is to build the best imaginable software architecture freed of any existing constraints.
The summary of this blog is organized hierarchically and chronologically. If you are not familiar with the ISA blog, it offers a more friendly navigation.
In ISA, the memory is managed thru smart pointer because of the efficiency and simplicity of this approach. On usual systems, the O.S. also provides Processes. To free objects, the process wall is broken by ISA! But this implies some memory management adjustments.

First, because it is really hard to conceive and understand a generic algorithm. This goes at contrary of the Wish N°5 – Simple and freed of experts. In my professional life, I have often …
Continue reading To be or not to be GenericThe object identifier production is one of the most important thing in an OO Architecture, and even more when it is a distributed one. This post is about some key items of the Identity axiom. Its major concerns are integrity, isolation and performance.
Continue reading Generation algorithms of Object idRegular followers of this blog may have noticed a low posting rate. This is not because this blog is dead: not at all. But I am working since a long time on the LL model and meta-model. This is an accurate, hard and also time consuming work. Moreover, I am …
Continue reading Introduction to Concepts AssemblyIn a recent brainstorming post, I stated that in ISA having a typed system every where, using the right type at the right place, is certainly a very good policy.
In the current IT world this obviously not the case. We often need, among others, to encode binary data into text. This give several declination like hexadecimal, base 64, etc.
This post is some kind of tutorial on the Last Language type system. Not just a tutorial in fact, but a discussion space to challenge the ISA type architecture.
Continue reading Overview of the LL type systemWhat are the major guidelines for LL? Simple (as Basic and PHP), Powerfull (like C++ or Smalltalk), Consistent (as OO is), Efficient (as C++ and Python), Dynamic but not messy, Seamlessly to suit to the whole software life cycle.
Continue reading LL basics and syntaxAfter stating that LL is the language to express ISA, comes the time to define the content expressed: The whole software developpement stack (just this !). From the idea to the production, in going thru the coding, the testing and the other major tasks of our industry.That’s the opportunity to state the ISA software process steps and also the delivered artefacts.
Continue reading What to express ? The ISA roadmapHow to express ISA ? The conclusion here is that building a first round of LL is the best answer. A warm up lap before the real start of the ISA solutions.
Continue reading What language to express ISA?The scope, background and foundations of ISA are now well established. It is time to examine the existing principles, the concepts and artefacts that are not useful for us. To reverse our point view in order to enumerate the existing things that must be avoided.
