Is Java seen as a pure object-oriented language or not?NexSoftsys
Java is seen as a purely object-oriented programming language as it is considered impossible for developers to write any Java program without its class and object, which is why it is not a pure object-oriented programming language.
Why Java is not a purely object oriented language?NexSoftsys
Java is not purely object oriented language but to say hybrid language because java not support complete OOP concept. It also called java is primitives programming language.

Live typing: Update and what's next by Hernan WilkinsonFAST
Last year I presented Live Typing, a new idea about annotating types in Smalltalk. There have been a lot of improvements and new functionality has been added to it. I'll present them and show what is coming up.
What comes to your mind when you hear the word "type"? Do you think of an integer or string? Do you think of an object type from your favorite OOP language? Do you think about never ending religious debates regarding static vs dynamic types? Do you realize that these things hardly scratch the surface of what it means to be a "type"? Be prepared to understand types on a whole new level.
In this talk, we will explore type systems. What is a type system? Why are type systems important? How have type systems been influenced by functional programming, category theory, and type theory?
We will talk about variance, polymorphisms, higher-kinded types, existential types, algebraic data types, and type classes. We will scratch the surface of type theory and learn how logic systems have influenced programming language design.
This talk will be approachable to a wide audience and previous knowledge of type theory is not needed.
The presentation starts with some basic theory on types. Later, different classifications for type systems are described, with the static/dynamic and strong/weak dimensions the ones we spend more time on.
The third topic addressed is how the mix of polimorsfism with covariance and descendant hiding affects the type system, and what new problems arise and have to be addressed by the type system.
We finished the presentation with a discussion about pros and cons of the PHP type system.

Launch Your Streaming Platforms in MinutesRoshan Dwivedi
The claim of launching a streaming platform in minutes might be a bit of an exaggeration, but there are services that can significantly streamline the process. Here's a breakdown:
Pros of Speedy Streaming Platform Launch Services:
No coding required: These services often use drag-and-drop interfaces or pre-built templates, eliminating the need for programming knowledge.
Faster setup: Compared to building from scratch, these platforms can get you up and running much quicker.
All-in-one solutions: Many services offer features like content management systems (CMS), video players, and monetization tools, reducing the need for multiple integrations.
Things to Consider:
Limited customization: These platforms may offer less flexibility in design and functionality compared to custom-built solutions.
Scalability: As your audience grows, you might need to upgrade to a more robust platform or encounter limitations with the "quick launch" option.
Features: Carefully evaluate which features are included and if they meet your specific needs (e.g., live streaming, subscription options).
Examples of Services for Launching Streaming Platforms:
Muvi [muvi com]
Uscreen [usencreen tv]
Alternatives to Consider:
Existing Streaming platforms: Platforms like YouTube or Twitch might be suitable for basic streaming needs, though monetization options might be limited.
Custom Development: While more time-consuming, custom development offers the most control and flexibility for your platform.
Overall, launching a streaming platform in minutes might not be entirely realistic, but these services can significantly speed up the process compared to building from scratch. Carefully consider your needs and budget when choosing the best option for you.

Live Typing - California Smalltalkers
1. Live Typing
A Type System for Smalltalk
Hernán A. Wilkinson - @hernanwilkinson
10Pines founder – Professor at UBA
agile software development & services
2. Hernán Wilkinson
Ø10Pines Founder
ØFAST Founder
(Fundación Argentina de Smalltalk)
ØProfessor at Computer Science
Department at UBA
....
Ømainly, passionate programmer
4. There are mainly two ways to have type
information in dynamically typed languages:
ØType Inference
ØManual Type Annotation
(generally combined with type inference)
14. Let’s see an example with Python 3.9
and PyCharm 2020.3
15. •Language syntax has to be changed
•Code is harder to read due to type annotations
•It is not like it was before …
•The programmer must annotate the types
•The programmer must maintain the annotations!
•They concentrate on type checking
•Tool improvements rely on each particular IDE
Disadvantages
17. There are mainly two three ways to have type
information in dynamically typed languages:
ØType Inference
ØManual Type Annotation
ØAutomatic Type Collection
18. Automatic type collection (done by the VM)
+
Tools that improve the development experience
Live Typing
19. As we saw, it is not a new idea…
but a particular one with a
working implementation
20. Live Typing’s goal is not
Type Checking
Its goal is to improve the tools to
facilitate the programmer’s tasks
(although it provides a type checking solution)
23. Instance variables – VM Change
ØEvery time a newObject is assigned to a variable, the VM stores ”newObject
class” into “instanceVariablesRawTypes at: (self indexOf: variable)”
26. Instance variables
ØinstanceVariablesRawTypes can be nil.
ØIt means we don’t want to store types for that class instance variables
ØinstanceVariablesRawTypes at: instVarIndex
ØCan be nil if we don’t want to store types for that instance variable
ØIt can have different sizes per instance variable to adjust memory consumption and
speed
27. Method Type Information
ØNew AdditionalMethodState instance variables:
ØvariablesTypes: Keeps arguments and temporaries types. Same structure as
instanceVariablesRawTypes
ØreturnTypes: Keeps return types
43. Performance
Typed VM Stack VM Difference
Aconcagua Tests 37 ms 22 ms 1.6 x
Chalten Tests 2400 ms 2204 ms 1.08 x
Refactoring Tests 56382 ms 39650 ms 1.42 x
TicTacToe Tests 3 ms 2 ms 1.5 x
Some Kernel Tests 220 ms 151 ms 1.45 x
Average 1.41 x
The important thing is that the programmer does
not notice the difference when programming
54. Under development
🔜 Annotate types in closure parameters and variables (Ines Sosa)
🔜 Support for Parameterized types (Generics) is needed for
collections, association, etc. (Collection<T>, Association<K,V>, etc.)
(Ana Felisatti & Mariano De Sousa)
🔜 Implement it on the JIT VM (?)
🔜 More refactorings types aware like inline (Fernando Balboa)
55. More Ideas
Ø Add more type cast cases in the Type Checker
Ø Check for parameter types (Freeze annotated types)
Ø Use Type Checker infrastructure to improve even more the autocomplete
Ø Suggest only the objects that type check for parameters
Ø Import type info from production images to development images
Ø Improve Type Checker to warn about dead code
Ø Delete method with transitive closure of actual sends in that method
Ø Change the COMPILER (not the VM) to generate and initialize the PIC at
compile time!!
