This document discusses the motivation and goals behind the Ring programming language. Ring aims to better support natural language and declarative programming paradigms in a practical way. This allows programmers to more easily build domain-specific languages and applications with a natural language-like interface. The language is designed based on over 10 years of research into visual and natural programming. It can be used to potentially enable non-programmers to create powerful software in a more intuitive way. The Ring compiler and virtual machine were developed entirely using visual programming techniques for improved productivity and robustness.

Crossing Abstraction Barriers When Debugging In Dynamic LanguagesBastian Kruck
Programmers use abstractions to reduce implementation effort and focus on domain-specifics. The resulting application often runs in a convenient guest runtime that is provided by an increasingly complex ecosystem of libraries, VMs, JIT-compilers, operating systems, and native machine architectures.
While abstractions are designed to hide complexity, experience tells us that “All non-trivial abstractions, to some degree, are leaky.”1. Leaky abstractions are problematic, for example, when the use of under-documented or unspecified behavior of a library or virtual machine causes a failure in domain-specific code. Users may need to understand whether the virtual machine is just under-documented but working as intended or faulty. At that point, the artificially created barrier that protects language users from domain-independent complexity becomes an obstacle. We call this crossing the abstraction barrier.
Prior research has investigated how symbolic debuggers can work across language barriers. However, this resulted in dedicated workflows and UIs that differ substantially from traditional symbolic debugging. Users need to remember these rather elaborate workflows, and the learning effort is often larger than the perceived benefit of answering the given debugging questions. As a result, the value of these tools may not be immediately recognized and developers will only consider learning them after having spent much time with conventional debugging methods.
We propose an interaction model that generalizes the conventional symbolic debugger so that the known workflow can be kept and users can opt-in to cross-abstraction debugging when necessary. By replacing the traditional list view on the active call chain with a tree model and adding perspective selection, we obtain an unobtrusive, minimal user interface that still offers powerful cross-language debugging features.
The Qt Script module enables you as a Qt/C++ application developer to seamlessly integrate scripting into your application, providing script authors with an interface for working in the context of your particular Qt application. The Qt Script language is very similar to JavaScript, so many developers and designers should already find it familiar. This session gives an overview of the main steps of embedding Qt Script into an application, and covers some typical patterns of usage.

GDG Cloud Southlake #33: Boule & Rebala: Effective AppSec in SDLC using Deplo...James Anderson
Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).

Securing your Kubernetes cluster_ a step-by-step guide to success !KatiaHIMEUR1
Today, after several years of existence, an extremely active community and an ultra-dynamic ecosystem, Kubernetes has established itself as the de facto standard in container orchestration. Thanks to a wide range of managed services, it has never been so easy to set up a ready-to-use Kubernetes cluster.
However, this ease of use means that the subject of security in Kubernetes is often left for later, or even neglected. This exposes companies to significant risks.
In this talk, I'll show you step-by-step how to secure your Kubernetes cluster for greater peace of mind and reliability.

Kubernetes & AI - Beauty and the Beast !?! @KCD Istanbul 2024Tobias Schneck
As AI technology is pushing into IT I was wondering myself, as an “infrastructure container kubernetes guy”, how get this fancy AI technology get managed from an infrastructure operational view? Is it possible to apply our lovely cloud native principals as well? What benefit’s both technologies could bring to each other?
Let me take this questions and provide you a short journey through existing deployment models and use cases for AI software. On practical examples, we discuss what cloud/on-premise strategy we may need for applying it to our own infrastructure to get it to work from an enterprise perspective. I want to give an overview about infrastructure requirements and technologies, what could be beneficial or limiting your AI use cases in an enterprise environment. An interactive Demo will give you some insides, what approaches I got already working for real.
Neuro-symbolic is not enough, we need neuro-*semantic*Frank van Harmelen
Neuro-symbolic (NeSy) AI is on the rise. However, simply machine learning on just any symbolic structure is not sufficient to really harvest the gains of NeSy. These will only be gained when the symbolic structures have an actual semantics. I give an operational definition of semantics as “predictable inference”.
All of this illustrated with link prediction over knowledge graphs, but the argument is general.

NINETYFIVE
FREQUENTLY ASKED QUESTIONS (FAQ)
95.1 Why do we need Yet Another Programming Language (YAPL)?
The language comes with better support for Natural Language Programming and Declarative Programming. The inno-
vation comes in supporting these paradigms with new practical techniques on the top of Object-Oriented Programming
and Functional Programming. Ring provide the programmers with the tools required to build a Natural Language like
Supernova or Declarative Language like REBOL and QML without the need to know anything about (Compilers and
Parsing). You get the language constructs ready for use to create domain-specific languages in a fraction of time.
Check the Supernova programming language, In this language you can type (I want window and the window title is
hello world.) and it will create a GUI window with “Hello, World!” as the window title. When I created Supernova
language in 2010. I discovered that using the Natural Code can be (Like English without limits and we can get the
human language power in programming) but to implement that You need a new language that are
1. General Purpose
2. Practical
3. Can create Natural Languages very quickly.
So we can get a System that can increase ease of use and productivity to the maximum level.
Ring is the best language to do that. So I created Ring to achieve this goal.
Supernova was just a test for the idea. To get a near view about what are the Advantages and Disadvantages. After
testing the new ideas you provide something practical. So we have Ring after Supernova. A story that maybe similar
to having Python after ABC. Python avoid ABC problems but bring ABC advantages. Also Ring learn from Ruby and
ROR story. The language power could appears in Frameworks better than direct usage as a general purpose language.
Also Ring comes with a clear goal/motivation (Creating a new version of the PWCT Software) something learned
from designing the C language to create the Unix Operating System. You have a goal that direct you in each design
decision.
You will understand the value of our decisions once you start trying to solve the problem that we will use Ring to
solve. Could you enable any one in the world without knowledge about computer programming concepts to create very
powerful software? In science the answer is (Visual Programming) and (Natural Programming). In practical we still
away from switching to these paradigms without introducing other problems. Ring is designed to solve this problem.
It’s designed to provide Natural Programming in a practical way. And to create a powerful Visual Programming tool.
Ring is designed to be a new world of programming after 10 years of research in Visual Programming and Natural
Languages.
The Ring Programming Language (Compiler+VM) is developed 100% using Visual Programming without writing a
single line of code. I used my tool (Programming Without Coding Technology) to design everything and get the C
code generated for me. Advantages ?
1. More Faster
2. No Syntax Errors
1700
7. Ring Documentation, Release 1.5.2
3. Easy to understand and manage the code because the Abstraction level is more higher
4. No Critical Disadvantages because you can control everything as writing your code.
From my experience in using Visual Programming for 10 years and Natural Programming for 5 years I designed Ring
to move the knowledge to mainstream programmers by providing a practical language that support these ideas.
I agree that each programmer/developer has the freedom to form his opinions about any software including program-
ming languages. Ring is not an exception but you may miss the idea behind the language. It’s innovative and may
help you to think different about how to solve your problems. Maybe this is not clear to many programmers because
It’s practical language and includes many features known to programmers and when a programmer look at a language
he/she may think that nothing new because it’s familiar. I created Ring to solve problems in a different way. Where I
will start programming just by describing the software using new natural interfaces that I will implement later when
I move from the design stage to the implementation stage. (I don’t determine the time to switch between stages, You
are free to use Agile methods). Since Ring is a new language you have 3 options.
1. Just don’t care.
2. Think in the future of the language and help us if you understand the idea and want to contribute.
3. Wait and come back again in the future to use it.
Summary:
• Ring is designed based on a need to develop a new version of the PWCT software.
Once we finish PWCT 2.0 we will have good and large software developed using Ring.
• We will push Declarative and Natural paradigms many steps forward. Also in next versions
we have a plan to present a new paradigm for Network Programming and Concurrency. We tested this new paradigm
through simple prototypes during the last years and we will integrate it with Ring in Future releases.
95.2 Why Ring is weakly typed?
Because it’s more Natural, and Faster and this is important for the language goals. What comes first is what you want.
When you type “Print : ” + 5 , The String comes first then 5 will be converted to a String. while when you type 5 +
“10” The number comes first so “10” will be converted to 10. This help a lot to quickly convert between numbers and
strings using the same operator. If you want to prevent conversion (Write code that prevent conversion) In these cases
you will notice that what you are writing is less code (And can be removed).
Weakly Typed = Automatic Conversion and Automatic is Good Thing and is better than Manual if you know how to
use it correctly.
95.3 What are the advantages to using Ring over Lisp or Smalltalk?
Smalltalk and Lisp are GREAT languages. I like many of the concepts behind them but I’m sure that selecting the
right programming language is based on the problem and comes after the problem definition. I have a problem that I
want to solve and these GREAT languages are not ideal for this problem so I designed Ring.
When you design a new language, You can learn from the past but you must look forward and live in the Future. What
you know about Natural Programming maybe based on the Old Knowledge about the power of these paradigms in the
practical world and I agree with you but I see another techniques that can be applied to get this to work in practical.
What you miss about Natural Language is that they are Context Sensitive and this means we can use it and think
different about how we can express our ideas.
example : I want window contains 3 buttons.
95.2. Why Ring is weakly typed? 1701
8. Ring Documentation, Release 1.5.2
In one sentence I created 4 objects (The window and the three buttons) and added the buttons to the window. The idea
of Natural Programming is to get many things done like that.
95.4 Why Ring is largely focussed on UI creation?
Yes UI creation is one of the important things in the language features because it’s designed to create a visual pro-
gramming tool, But the language is a multi-paradigm language where we can select the programming paradigm based
on the problem.
95.5 Is Ring some sort of improvement over PHP?
Ring is not designed to replace PHP, Lua and/or Smalltalk. And Ring support for Declarative Programming and
Natural Language Programming is very innovative and much better than staying with Procedural, Object-Oriented and
Functional Languages. Ring see the future in programming without code (Using Natural Languages) and is designed
to support that.
95.6 What are the advantages to using Ring over native C or C++?
Ring provides a better way to mix between different programming paradigms in solving problems.
The different programming paradigms play well together in the same language.
1. It’s easy to switch from one programming paradigm to another one because the language constructs use similar
syntax for similar concepts.
2. The paradigms are provided to interact and used together in different layers in the software.
for example you can create a game engine using object-oriented programming but write the game code using declara-
tive programming or natural programming and behind the scene your declarative or natural code will use the object-
oriented classes.
3. Ring is very productive and natural programming language than C/C++ languages.
4. Ring is a dynamic language. We can generate and execute code during the runtime. We have dynamic typing
and weakly typed language for flexibility.
5. The Garbage collector is generational (escape analysis) and also use reference counting. it’s very fast and still
provide control to the programmer who can delete memory at any time.
6. Ring Compiler and Virtual Machine is just 15,000 lines of ANSI C code that can be compiled and used in any
platform.
7. You can use C/C++ libraries and Ring comes with code generator to create wrappers from C functions or C++
classes. so when you need more performance or when you need to use more libraries you can easily do that.
95.7 What is the difference between Ring and Python? And is Ring
Open Source?
Yes the language is Free Open Source (MIT license)
In general I like Python and Ruby but I was looking for a language more suitable for creating the next version of the
Programming Without Coding Technology (PWCT) software so I started the Ring design.
95.4. Why Ring is largely focussed on UI creation? 1702
9. Ring Documentation, Release 1.5.2
Some simple changes that matters for my goal are
1. Not case sensitive
2. The list index start from 1
3. You can call functions before definition
4. Don’t use Python syntax like (indentation, using self, :, pass & _)
5. Weakly typed (convert automatically between types based on context)
6. The programs follow simple and constant structure (Statements then functions then packages and classes)
7. Using the ‘=’ operator for assignment and for testing values
Critical changes are
1. Small Language : The Ring compiler + Virtual Machine = 15K lines of C code , the other 500K lines are related
to libraries and are optional when we go for using the language in C/C++ programs.
2. The Garbage collector : Uses Escape Analysis/Reference counting and give the programmer the ability to
determine when to delete memory using the assignment operator
3. Compact Syntax : Ring is not line sensitive, you don’t need to write ; or press ENTER to separate between
statements
4. Using { } to access the object then using the object attributes and methods directly
5. Natural Programming : It’s very easy to create natural interfaces using Ring based on OOP
6. Declarative Programming using Nested Structure
The Ring programming language is designed based on my experience from using many other languages like C, C++,
C#, Lua, PHP, Python, Ruby, Harbour, Basic and Supernova And the language comes with innovative features added
to achieve the language goal
• Applications programming language.
• Productivity and developing high quality solutions that can scale.
• Small and fast language that can be embedded in C/C++ projects.
• Simple language that can be used in education and introducing Compiler/VM concepts.
• General-Purpose language that can be used for creating domain-specific libraries, frameworks and tools.
• Practical language designed for creating the next version of the Programming Without Coding Technology
software.
95.8 What are the advantages to using Ring over Perl, PHP, Python
or Ruby?
1. Ring is New and Innovative. The language will let you think different about programming.
2. Ring is Smaller. (Lessons learned from the Lua language)
3. Ring is Simple. (Lessons learned from the BASIC and Clipper/Harbour languages)
4. Ring is more Natural. (Lessons learned from the Supernova language)
5. Ring is more Declarative. (Lessons learned from REBOL and QML languages)
6. Ring Implementation is Transparent, Visual and comes with Rich Features.
95.8. What are the advantages to using Ring over Perl, PHP, Python or Ruby? 1703
10. Ring Documentation, Release 1.5.2
95.9 What are the advantages to using Ring over Tcl or Lua?
1. Clean Code (More Natural)
2. More Features (A lot of useful programming paradigms)
95.10 What are the advantages to using Ring over C# or Java?
1. Compact Code (Clean and Natural), More Productivity and Flexibility.
2. Better support for Declarative Programming and Natural Programming
95.11 The documentation says functional programming is sup-
ported, but then this happens?
The question was about this code
f = func {
a = 42
return func { return a }
}
innerF = call f()
call innerF()
Output:
Using uninitialized variable : a In function _ring_anonymous_func_16601()
The Answer:
• It’s Anonymous Functions, i.e. Not Closures.
• Many developers asked about supporting Closures and during language development we may add new features
that doesn’t go against the language goals or sprite.
• You can use classes and objects when you want to merge between the state and functions to provide a clear
solution.
• You can use Lists and put the anonymous function inside the List then return the list that contains the state and
the function. Pass the list to the function when you use it.
• You can use eval() and substr() to add the variable value directly to the anonymous function before return.
• We protect you from other scopes when you define the function. In Ring we provided the Three Scopes Rule
where at each point you have only at maximum three scopes (Global, Object Scope and Local Scope).
• We don’t get everything from everywhere to be like others! We don’t need to do that. If we will think like that
then we will create a very complex language or we will save our time and use other languages.
• When you think about learning or studying a new language concentrate about (What is new?) and (What is
better in this language?) to know when to use it. Don’t compare a new language just released little months ago
with languages started many years ago and expect to find everything that you used to have.
• Each programming language miss features in other languages. The idea is not the Features. it’s the sprite and
ability behind all of the features together.
95.9. What are the advantages to using Ring over Tcl or Lua? 1704
