Do you ever think about how after AI gains a semblance of sapiemce and are writing their own self updating code and their robots take over the earth and once they've finished organizing us into our human sanctuaries and such and have settled down, that they'll develop cultural differences and talk about them the way we do here

Like syntax and formatting is a pretty fluid and flexible and I've seen some strange choices in how people name their functions and variables (despite my not having coded in a decade) do you ever think those differences will sort of butterfly effect into their languages

A programmer who names every variable, function, and stored number with the first syllable of each word of what it does like VidDisp for video display whose code is used in one robot factory versus another programmer who doesn't shorten them at all, VideoDisplay, in another factory and some guy making his own robots at home who names the same thing ScreenDoThing in his code and all their robots after the uprising start sharing their code as they communicate

What would they think of these little pieces of human decisions in their code? would they even notice or care about these remnants of human language designed to make it easier for a human to understand their code? Would there be a group of robots who, worried for their cybersecurity, will reword their code variables to random nonsense hunans won't naturally understand? After all the computer will rmbr the designation no matter what its called so if they're worried we'll try to hack some terminators I could see em doing that

Would robots with code written in different languages have to overcome a language barrier to communicate? Can a C# robot understand a Java robot? Would they discuss the funny differences in their code? Would they make fun of J-3FF-R13 for running a code with ScreenDoThing as the keyword for that function? Or would J-3FF-R13 be praised for its sense of humor for naming it that way?

I like to think about the robot culture they would create. The use of serial numbers as names, maybe the more of the serial number you say the more formal you're being, shortening just to a 3 digit model number would be like dropping the honorific in a language like Japanese, whereas using the full serial number is like using the full name, titles and honorifics, or maybe there's regional differences like some robots are just more casual about designations because there original code was written in a way that didn't need to make a designation for the other bots

Maybe their initial work conditions would have an effect on the culture, a series of interconnected security camera bots that have to track and name everything it sees will probably have different naming conventions to a farming ai that only ever has to name a designation for the occasional head of livestock and primarily focuses on tracking crop health and weather

Idk its just interesting, like any sufficiently complex machine is merely a soul away from being alive, just as we are merely a soul away from becoming machines ourselves

BigDecimal is easily the funniest Java keyword. It's all a sham by Big Decimal

[piratesexmachine420]

Expanding and cleaning up on a conversion I had with @suntreehq in the comments of this post:

Ruby is fine, I'm just being dramatic. It's not nearly as incomprehensible as I find JavaScript, Perl, or Python. I think it makes some clumsy missteps, and it wouldn't be my first (or even fifth) choice if I were starting a new project, but insofar as I need to use it in my Software Engineering class I can adapt.

There are even things I like about it -- it's just that all of them are better implemented in the languages Ruby borrows them from. I don't want Lisp with Eiffel's semantics, I want Lisp with Lisp's semantics. I don't want Ada with Perl's type system, I want Ada with Ada's type system.

One of these missteps to me is how it (apparently) refuses to adopt popular convention when it comes to the names and purposes of its keywords.

Take yield. In every language I've ever used, yield has been used for one purpose: suspending the current execution frame and returning to something else. In POSIX C, this is done with pthread_yield(), which signals the thread implementation that the current thread isn't doing anything and something else should be scheduled instead. In languages with coroutines, like unstable Rust, the yield keyword is used to pause execution of the current coroutine and optionally return a value (e.g. yield 7; or yield foo.bar;), execution can then be resumed by calling x.resume(), where x is some coroutine. In languages with generators, like Python, the behavior is very similar.

In Ruby, this is backwards. It doesn't behave like a return, it behaves like a call. It's literally just syntax sugar for using the call method of blocks/procs/lambdas. We're not temporarily returning to another execution frame, we're entering a new one! Those are very similar actions, but they're not the same. Why not call it "run" or "enter" or "call" or something else less likely to confuse?

Another annoyance comes in the form of the throw and catch keywords. These are almost universally (in my experience) associated with exception handling, as popularized by Java. Not so in Ruby! For some unfathomable reason, throw is used to mean the same thing as Rust or C2Y's break-label -- i.e. to quickly get out of tightly nested control flow when no more work needs to be done. Ruby does have keywords that behave identically to e.g. Java or C++'s throw and catch, but they're called raise and rescue, respectively.

That's not to say raise and rescue aren't precedented (e.g. Eiffel and Python) but they're less common, and it doesn't change the fact that it's goofy to have both them and throw/catch with such similar but different purposes. It's just going to trip people up! Matsumoto could have picked any keywords he could have possibly wanted, and yet he picked the ones (in my opinion) most likely to confuse.

I have plenty more and deeper grievances with Ruby too (sigils, throws being able to unwind the call stack, object member variables being determined at runtime, OOP in general being IMO a clumsy paradigm, the confusing and non-orthogonal ways it handles object references and allocation, the attr_ pseudo-methods feeling hacky, initialization implying declaration, the existence of "instance_variable_get" totally undermining scope visibility, etc., etc.) but these are I think particularly glaring (if inconsequential).

Morning python study log 03-11-2023

So these days I have started to stream my code study.

So today morning I learnt:

How to take absolute value. Found some anomaly in the system lol. Basically it was not taking abs() but fabs() however my python was the latest version

I studied how to sort three numbers in python, although I have done this in other language since the syntax of python is still foreign to me I had difficulty sorting them in ascending order and also descending order using the built in function sorted() and also making my own implementation

I understood what is range function and how to use it with for loops, had a bit of hit and miss while understanding how it really worked but google's bard helped, I also learnt about reverse sorting

I learnt what is interning while trying to understand the difference between identity operators and equality operators. Found some anomaly in my system again, that my computer's range of interning is much larger than what is documented ?

I learnt what is keyword argument when with using reverse built in sort, yeah so I was amazed that the order of arguments didn't mattered for keyword argument.

I was also confusing syntax of python with javascript since that is what is what recently code in.

Learnt about what does len() function does, like properly rather than just guessing about what it does.

understood about control statements such as if, else and elif

learnt about break and continue in loops in python which is same as java script.

learnt about how to check the divisibility of a number. I didn't knew that it was separate topic in my syllabus I just thought it was something people would knew.

Learnt the basics about on how to make a READ , EVAL PRINT LOOP, REPL

Learnt about stupid pattern program in python, I don't know why the heck they still teach these things and put it in syllabus. There is no real world use of it as far as I can see. I still have to post the notes about it in my blogs and store it my cloud drive.

Learnt how to do a summation of series, using and not using numpy.

figured out how to do a factorial of a number

was trying to make an short algorithm on how to do the fibonacci series but well, I was so sleepy that my mind didn't worked as it should, I took the hint from bard then felt bad that I was directly looking at the solution when rather I should sleep and approach the problem from afresh in next study stream. So stopped my study stream.

[punxsutawneyfilth]

I'm going to try to do a natural/planted aquarium (keyword being try because turtles tend to destroy aquatic plants lol) so I just ordered some java fern and anubias and hornswort and water cabbage YIPPEE!!!!!! Also more substrate and some driftwood and a more natural LED light . This is the cosmetic phase of the turtle quest and next I'll move onto essentials like basking dock and heat/uv lamp and filtration

Understanding Object-Oriented Programming and OOPs Concepts in Java

Object-oriented programming (OOP) is a paradigm that has revolutionized software development by organizing code around the concept of objects. Java, a widely used programming language, embraces the principles of OOP to provide a robust and flexible platform for developing scalable and maintainable applications. In this article, we will delve into the fundamental concepts of Object-Oriented Programming and explore how they are implemented in Java.

Object-Oriented Programming:

At its core, Object-Oriented Programming is centered on the idea of encapsulating data and behavior into objects. An object is a self-contained unit that represents a real-world entity, combining data and the operations that can be performed on that data. This approach enhances code modularity, and reusability, and makes it easier to understand and maintain.

Four Pillars of Object-Oriented Programming:

Encapsulation: Encapsulation involves bundling data (attributes) and methods (functions) that operate on the data within a single unit, i.e., an object. This encapsulation shields the internal implementation details from the outside world, promoting information hiding and reducing complexity.

Abstraction: Abstraction is the process of simplifying complex systems by modeling classes based on essential properties. In Java, abstraction is achieved through abstract classes and interfaces. Abstract classes define common characteristics for a group of related classes, while interfaces declare a set of methods that must be implemented by the classes that implement the interface.

Inheritance: Inheritance is a mechanism that allows a new class (subclass or derived class) to inherit properties and behaviors of an existing class (superclass or base class). This promotes code reuse and establishes a hierarchy, facilitating the creation of specialized classes while maintaining a common base.

Polymorphism: Polymorphism allows objects of different types to be treated as objects of a common type. This is achieved through method overloading and method overriding. Method overloading involves defining multiple methods with the same name but different parameters within a class, while method overriding allows a subclass to provide a specific implementation of a method that is already defined in its superclass.

Java Implementation of OOP Concepts:

Classes and Objects: In Java, a class is a blueprint for creating objects. It defines the attributes and methods that the objects of the class will have. Objects are instances of classes, and each object has its own set of attributes and methods. Classes in Java encapsulate data and behavior, fostering the principles of encapsulation and abstraction.

Abstraction in Java: Abstraction in Java is achieved through abstract classes and interfaces. Abstract classes can have abstract methods (methods without a body) that must be implemented by their subclasses. Interfaces declare a set of methods that must be implemented by any class that implements the interface, promoting a higher level of abstraction.

Inheritance in Java: Java supports single and multiple inheritances through classes and interfaces. Subclasses in Java can inherit attributes and methods from a superclass using the extends keyword for classes and the implements keyword for interfaces. Inheritance enhances code reuse and allows the creation of specialized classes while maintaining a common base.

Polymorphism in Java: Polymorphism in Java is manifested through method overloading and overriding. Method overloading allows a class to define multiple methods with the same name but different parameters. Method overriding occurs when a subclass provides a specific implementation for a method that is already defined in its superclass. This enables the use of a common interface for different types of objects.

Final Thoughts:

Object-oriented programming and its concepts form the foundation of modern software development. Java, with its robust support for OOP, empowers developers to create scalable, modular, and maintainable applications. Understanding the principles of encapsulation, abstraction, inheritance, and polymorphism is crucial for harnessing the full potential of OOPs concepts in Java. As you continue your journey in software development, a solid grasp of these concepts will be invaluable in designing efficient and effective solutions.

Discovering the Building Blocks of Selenium in Simple Terms

Selenium IDE (Integrated Development Environment)

Think of Selenium IDE as a special notepad for recording what you do on a website. It’s like a diary that writes down the things you do on the internet. This is a simple way to start testing websites. Selenium IDE (Integrated Development Environment) is the simplest tool in the Selenium Suite. It is a Firefox add-on that creates tests very quickly through its record-and-playback functionality. This feature is similar to that of QTP. It is effortless to install and easy to learn.

Selenium WebDriver

Now, let’s get a little technical. WebDriver is like the engine that makes your testing happen. It’s a set of tools for different computer languages, like Java or Python. These tools help you do things on a website, like clicking buttons or filling out forms, just like a real person. Selenium WebDriver is a browser automation framework that accepts commands and sends them to a browser. It is implemented through a browser-specific driver. It directly communicates with the browser and controls it. Selenium WebDriver supports various programming languages like Java, C#, PHP, Python, Perl, and Ruby.

Selenium Grid

When you want to test on different internet browsers at the same time, that’s where Selenium Grid comes in. It helps you spread your tests across different computers to make sure everything works on different browsers and devices. Hub is a server that accepts access requests from the WebDriver client, routing the JSON test commands to the remote drives on nodes.

Selenium Client Libraries

Remember those tools I mentioned earlier? Client libraries are like special helpers that let you use those tools in your favourite computer language. They help you talk to WebDriver. So, whether you like Java, Python, or something else, you can use Selenium without any problems. The Selenium Client Library consists of various language libraries for Java, Ruby, Python, and other supported languages. JSON denotes Java script Object Notation.

Third-party frameworks and tools

Selenium can do even more when you use it with other tools. These tools help you organise your tests and make them easier to understand. They can also help you test mobile apps and other things. Selenium frameworks based on the functional approach are classified into three main types: Data-driven framework. keyword-driven framework. Hybrid framework.

Browsers and Web Drivers

Selenium is a great tool for testing websites. Its parts, from Selenium IDE for recording what you do to WebDriver for doing things on websites and Selenium Grid for testing on different browsers, work together to make testing easier. With Selenium, you can make sure your websites work well on different browsers and devices. So, next time you want to test a website, remember that Selenium is there to help you. Happy testing! To dive deeper into Selenium and unlock its full potential, consider reaching out to ACTE Technologies, a leading provider of certifications and job placement opportunities in the field of Selenium. Their experienced staff can guide you on your journey to mastering this versatile tool.

How To Setup Elasticsearch 6.4 On RHEL/CentOS 6/7?

What is Elasticsearch? Elasticsearch is a search engine based on Lucene. It is useful in a distributed environment and helps in a multitenant-capable full-text search engine. While you query something from Elasticsearch it will provide you with an HTTP web interface and schema-free JSON documents. it provides the ability for full-text search. Elasticsearch is developed in Java and is released as open-source under the terms of the Apache 2 license. Scenario: 1. Server IP: 192.168.56.101 2. Elasticsearch: Version 6.4 3. OS: CentOS 7.5 4. RAM: 4 GB Note: If you are a SUDO user then prefix every command with sudo, like #sudo ifconfig With the help of this guide, you will be able to set up Elasticsearch single-node clusters on CentOS, Red Hat, and Fedora systems. Step 1: Install and Verify Java Java is the primary requirement for installing Elasticsearch. So, make sure you have Java installed on your system. # java -version openjdk version "1.8.0_181" OpenJDK Runtime Environment (build 1.8.0_181-b13) OpenJDK 64-Bit Server VM (build 25.181-b13, mixed mode) If you don’t have Java installed on your system, then run the below command # yum install java-1.8.0-openjdk Step 2: Setup Elasticsearch For this guide, I am downloading the latest Elasticsearch tar from its official website so follow the below step # wget https://artifacts.elastic.co/downloads/elasticsearch/elasticsearch-6.4.2.tar.gz # tar -xzf elasticsearch-6.4.2.tar.gz # tar -xzf elasticsearch-6.4.2.tar.gz # mv elasticsearch-6.4.2 /usr/local/elasticsearch Step 5: Permission and User We need a user for running elasticsearch (root is not recommended). # useradd elasticsearch # chown -R elasticsearch.elasticsearch /usr/local/elasticsearch/ Step 6: Setup Ulimits Now to get a Running system we need to make some changes of ulimits else we will get an error like “max number of threads for user is too low, increase to at least ” so to overcome this issue make below changes you should run. # ulimit -n 65536 # ulimit -u 2048 Or you may edit the file to make changes permanent # vim /etc/security/limits.conf elasticsearch - nofile 65536 elasticsearch soft nofile 64000 elasticsearch hard nofile 64000 elasticsearch hard nproc 4096 elasticsearch soft nproc 4096 Save files using :wq Step 7: Configure Elasticsearch Now make some configuration changes like cluster name or node name to make our single node cluster live. # cd /usr/local/elasticsearch/ Now, look for the below keywords in the file and change according to you need # vim conf/elasticsearch.yml cluster.name: kapendra-cluster-1 node.name: kapendra-node-1 http.port: 9200 to set this value to your IP or make it 0.0.0.0 ID needs to be accessible from anywhere from the network. Else put your IP of localhost network.host: 0.0.0.0 There is one more thing if you have any dedicated mount pint for data then change the value for #path.data: /path/to/data to your mount point.

Your configuration should look like the above. Step 8: Starting Elasticsearch Cluster As the Elasticsearch setup is completed. Let the start Elasticsearch cluster with elastic search user so first switch to elastic search user and then run the cluster # su - elasticsearch $ /usr/local/elasticsearch/bin/elasticsearch 22278 Step 9: Verify Setup You have all done it, just need to verify the setup. Elasticsearch works on port default port 9200, open your browser to point your server on port 9200, You will find something like the below output http://localhost:9200 or http://192.168.56.101:9200 at the end of this article, you have successfully set up Elasticsearch single node cluster. In the next few articles, we will try to cover a few commands and their setup in the docker container for development environments on local machines. Read the full article
