How to manage memory ?

22-Mar-2019

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.

To be or not to be Generic

4-Feb-2019

Thesis: Not to be generic At first, I didn’t want to include generics in LL. This is mainly for two reasons. 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 …

Overview of the LL type system

25-Dec-2017

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.

LL basics and syntax

16-Oct-2017

What 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.

What to express ? The ISA roadmap

22-Mar-2017

After 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.

What language to express ISA?

4-Feb-2017

How 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.

Useless concepts

21-Jan-2017

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.

Object Oriented Guidelines

4-Dec-2016

ISA relies on the Object Oriented paradigm. Let me now join OO with our wishes. Some guidances emerge . The first one is, not surprisingly, “Everything in ISA is an Object”!

The SOA paradigm case

31-Oct-2016

What is really the SOA? Analyzing pros and cons, is this a concept usable for ISA? This post conclude that no, it isn’t. OO is more powerful and provides a wider consistancy.
However, some SOA central properties have to be incorporated in ISA. Let’s have a look to them!

The State axiom – Part 4

24-Jun-2016

Here I study the Class Object state axiom in the perspective of an incorporation in ISA. What’s about the Class life cycle ? And about the Versioning, the Grouping and the Delivery ?
