I presented a whirlwind tour of the most common benchmark tools used to measure parallel file system performance and reviewed case studies of how these have been used in the procurement of NERSC's large file systems at the 2022 Lustre User Group.
Reduced instruction set computing, or RISC (pronounced 'risk', /ɹɪsk/), is a CPU design strategy based on the insight that a simplified instruction set provides higher performance when combined with a microprocessor architecture capable of executing those instructions using fewer microprocessor cycles per instruction.
Modern databases and its challenges (SQL ,NoSQL, NewSQL)Mohamed Galal
Nowadays the amount of data becomes very large, every organization produces a huge amount of data daily.
Thus we want new technology to help in storing and query a huge amount of data in acceptable time.
The old relational model may help in consistency but it was not designed to deal with big data problem.
In this slides, I will describe the relational model, NoSql Models and the NewSql models with some examples.

Operating system 24 mutex locks and semaphoresVaibhav Khanna
Mutual Exclusion - If process Pi is executing in its critical section, then no other processes can be executing in their critical sections
2. Progress - If no process is executing in its critical section and there exist some processes that wish to enter their critical section, then the selection of the processes that will enter the critical section next cannot be postponed indefinitely
3. Bounded Waiting - A bound must exist on the number of times that other processes are allowed to enter their critical sections after a process has made a request to enter its critical section and before that request is granted
Assume that each process executes at a nonzero speed
No assumption concerning relative speed of the n processes
В данном докладе мы рассмотрим пять основных принципов дизайна классов в объектно-ориентированном проектировании, которые известны, как принципы SOLID. А также как обеспечить достаточный уровень гибкости, связанности, управляемости, стабильности и понятности кода.
Concurrent and Parallel computing is explained in detail in the following presentation and the basic differences are cited with rel life examples and application.
Multithreading in java is a process of executing multiple threads simultaneously. The thread is basically a lightweight sub-process, the smallest unit of processing. Multiprocessing and multithreading, both are used to achieve multitasking.

For many years Object Oriented and Functional Programming have been considered diametrically opposite programming paradigms, with opposite communities.
Here we take the opposite point of view: they're two puppies from the same litter. Going through the well known SOLID Principles for good Object Oriented design and describing how some use of functional principles help improve the code.
What does OOP stand for?
When Object Oriented Programming(OOP) is taught so extensively, do computer programmers, specifically within games development, realise what it's possibly doing to productivity and performance? I explain my own view from experience in personal projects and professional work.
This talk was given to the Edinburgh meet of IGDA Scotland, on 2011/07/27.
This is a small recap of different SOLID principles.
The slides do not have much comments but if you follow the link, you will get all the examples and they are self explanatory.
"Leveraging the Event Loop for Blazing-Fast Applications!", Michael Di PriscoFwdays
Can the Microtask Queue help you improve your performances by 100x? It turns out it can, but how? JavaScript is single-threaded, yet it provides a really powerful Event Loop to allow non-blocking operations, so let's try to tame this beast together and get the most out of it! As I like to say: The Event Loop is the only infinite loop you'll love.
The course aims to provide you with an understanding of the fundamental concepts involved in object-oriented programming (object, class, protocol, hierarchy, inheritance, encapsulation, polymorphism and collaboration).
The programming language you will use is Java. However, the purpose of the course is not to teach you the minutiae of the Java language, but rather to teach you fundamental object-oriented programming concepts and skills that will be transferable to any object¬ oriented language
This Book helps the students who are persuing B.Sc Computer Science in Andhra Pradesh. It made for learning in easiest way. Words have used in this book are very familiar. Any one can understand the language easily. Prefer this book to learn Java.
Cosa sono i microservizi? Perché li devo usare? Sono una moda? In alcuni dicono che siano una soluzione "standard", altri dicono che non si dovrebbero usare, altri ne negano l'esistenza... Ma chi sviluppa software e deve portare a casa un po' di software che funziona... cosa deve fare?
Proviamo a vedere e a capire da dove arrivano, cosa sono e quali caratteristiche hanno, in modo da fare in ogni contesto una scelta una consapevole.
Elixir and Erlang share the same VM called BEAM. In this very practical demo, we discover some secrets of BEAM and OTP. This a refreshed version of an old presentations.
TDD is now mainstream but a lot people don't know or don't remember what is its purpose. TDD is about software design not testing or catching bug. TDD helps developers to shape and create software with "good" design, what is a "good" design is something that we will discuss in the topic.

These are slides of talk made at https://www.agilemovement.it/workingsoftware/schedule.html. In this talks I'll show how the concepts of DDD like aggregate, domains events, read model, command, CQRS and so on love the idea of Actor Model and how a languages like Elixir that is built on a real Actor Model VM like the BEAM, is very powerful to build software that take care of DDD/CQRS/ES.
Why should we use TDD to develop in Elixir? When we are applying it correctly? What are the differences that we can find in a code developed with TDD and in code not developed with it? Is it TDD about testing? Really? In this talk, I'll show what is TDD and how can be used it in functional programming like Elixir to design the small and the big parts of your system, showing what are the difference and the similarities between an OOP and FP environment. Showing what is the values of applying a technique like TDD in Elixir and what we should obtain applying it.
In this talk, I'll explain how the current web applications are no more simple DB projections but more complex and distributed applications that require technologies and architectures different from the past. We start with a simple & classic application to move to a more complex and feature-rich application that need a more advanced architecture.
Workshop on how, using RabbitMQ and Elixir, we can integrate a lot of different application written in different languages (Java, .NET, js, ruby, python and C++) with different protocols AMQP and MQTT.
Docker & GitLab as a Continuous Integration platform. In this talk we describe how we use gitlab and docker as a platform to implement Continuous Integration in a simple and effective weay.
In questo talk farò vedere il primo approccio ad Elixir in un semplice caso reale. Vedremo cosa significa sviluppare un piccolo servizio in Elixir e quanto l'ecosistema sia pronto per andare in produzione.
Can we move beyond threads and locks to manage concurrency? Are there more advanced models than threads and locks? How do other languages manage the concurrency?
We see some examples in others languages and a possible solution in C++.

The French Revolution, which began in 1789, was a period of radical social and political upheaval in France. It marked the decline of absolute monarchies, the rise of secular and democratic republics, and the eventual rise of Napoleon Bonaparte. This revolutionary period is crucial in understanding the transition from feudalism to modernity in Europe.

2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.

Understanding the importance of synthetic fibers helps in appreciating their role in the economy, industry, and daily life, while also emphasizing the need for sustainable practices and innovation.
2. The beginning ...
About a year ago, I said to a friend:
"Why is it called 'OOP'? It should be called
'COP' as the classes are more important!"
...my friend stopped saying "ciao" to me for a
month...he works in Python and Javascript!
3. The beginning ...
Some time later I saw this post of Uncle Bob
"The Last programming Language" where he
talks about Clojure and I read a phrase that left
a strong impression on me:
Inheritance is not the only way to do polymorphism
4. The beginning ...
Then I discovered this book. At
the moment this is the best
book that I have ever read
about TDD and design ...
5. The beginning ...
Then I began to study Ruby and work in
Javascript.
In Javascript the concept of class does not
exist!
In Ruby the objects are softer than in C# or
Java.
6. OOP - Ruby
irb(main):001:0> a = [1, 2]
=> [1, 2]
irb(main):002:0> a.somma()
NoMethodError: undefined method `somma' for [1, 2]:Array
from (irb):2
from C:/Ruby192/bin/irb:12:in `<main>'
irb(main):003:0> def a.somma()
irb(main):004:1> self.inject(:+)
irb(main):005:1> end
=> nil
irb(main):006:0> a.somma
=> 3
irb(main):007:0>
7. OOP - Javascript
var obj = {
type: "xxx",
color: "red",
getInfo: function () {
return this.type + ' is ' + this.color;
}
};
obj.color = "black";
alert(obj.getInfo());
8. Language matters!?
Is it just a language problem or is there
something else?
Let's start from the beginning ...
13. Let's ask "Dad"...
http://en.wikiquote.org/wiki/Alan_Kay
"OOP to me means only
messaging, local retention and
protection and hiding of state-
process, and extreme late-
binding of all things. It can be
done in Smalltalk and in LISP.
There are possibly other
systems in which this is
possible, but I'm not aware of
them."
14. So OOP is:
● Messaging
● Local retention & protection
● Hiding of State-process
● Extreme late binding
17. Let's ask Alan again...
http://userpage.fu-berlin.
de/~ram/pub/pub_jf47ht81Ht/doc_kay_oo
p_en
"It was probably in 1967 when someone asked me what
I was doing, and I said: 'It's object-oriented programming'."
[...]
"I thought of objects being like biological cells and/or
individual computers on a network, only able to
communicate with messages (so messaging came at the
very beginning -- it took a while to see how to do
messaging in a programming language efficiently enough
to be useful)."
18. Let's ask Alan again...
http://lists.squeakfoundation.org/pipermail/squeak-
dev/1998-October/017019.html
"Just a gentle reminder that I took some pains at the last
OOPSLA to try to remind everyone that Smalltalk is not
only NOT its syntax or the class library, it is not even
about classes. I'm sorry that I long ago coined the term
"objects" for this topic because it gets many people to
focus on the lesser idea."
The big idea is "messaging" [ ... ]
19. Why OOP ...
OOP creates a modular design that is easily
modified without having to restructure the entire
system.
20. Why OOP ...
Keeps large software projects manageable for
human programmers
21. Why OOP ...
Keeps large software projects manageable for
human programmers via:
Modularization - Decompose problem into
smaller subproblems that can be solved
independently.
22. Why OOP ...
Keeps large software projects manageable for
human programmers via:
Abstraction -- Understandability - Terminology
of the problem domain is reflected in the
software solution. Individual modules are
understandable by human readers.
23. Why OOP ...
Keeps large software projects manageable for
human programmers via:
Encapsulation -- Information Hiding - Hide
complexity from the user of a software or SDK.
Protect low-level functionality
24. Why OOP ...
Keeps large software projects manageable for
human programmers via:
Composability -- Structured Design - Interfaces
allow modules to combine freely in order to
produce new systems.
25. Why OOP ...
Keeps large software projects manageable for
human programmers via:
Hierarchy - Incremental development from
small and simple to more complex modules.
26. Why OOP ...
Keeps large software projects manageable for
human programmers via:
Continuity - Changes and maintenance in only
a few modules does not affect the overall
architecture.
29. OOP
The strongest concept of OOP is "messaging",
so while we are developing we should
concentrate on how the objects communicate
between themselves
30. OOP - System Level
When we develop a system we should focus
on:
● Separation of concern
● High level of abstraction
31. OOP - System Level
We obtain a Hexagonal Architecture
32. OOP - Object Level
How can we discover ports and adapters?
● Encapsulation
● Information Hiding
● Low Coupling
● High Cohesion
● Composite Simpler Than The Sum
● Context Independence
● Hide the correct information
33. OOP - Object Level
The objects should have:
● Low Coupling
● High Cohesion
● Composite Simpler Than The Sum
● Context Independence
● Hide the correct information
34. OOP - Object Level
We should compose the objects to describe the
system, so we have:
● Declarative Layer - Where the objects are
created and composed
● Application Layer - Where the object
communicates
35. And the classes???
The classes are "the declarative layer of the
declarative layer". The classes are "factories"
for the objects. So you could have other
factories for the objects...
36. OOP - Ruby
irb(main):001:0> a = [1, 2]
=> [1, 2]
irb(main):002:0> a.somma()
NoMethodError: undefined method `somma' for [1, 2]:Array
from (irb):2
from C:/Ruby192/bin/irb:12:in `<main>'
irb(main):003:0> def a.somma()
irb(main):004:1> self.inject(:+)
irb(main):005:1> end
=> nil
irb(main):006:0> a.somma
=> 3
irb(main):007:0>
37. OOP - Javascript
var obj = {
type: "xxx",
color: "red",
getInfo: function () {
return this.type + ' is ' + this.color;
}
};
obj.color = "black";
alert(obj.getInfo());
38. OOP - Scheme
(define (make-from-real-imag x y)
(define (dispatch op)
(cond ((eq? op 'real-part) x)
((eq? op 'imag-part) y)
((eq? op 'magnitude)
(sqrt (+ (square x) (square y))))
((eq? op 'angle) (atan y x))
(else
(error "Unknown op -- MAKE-FROM-REAL-IMAG"
op))))
dispatch)
40. Example
There is a web server that exposes some APIs
to manage playlists of images. We create a
desktop program to manage these playlists ...
