By Taylor Clark, Press & Written Media Team

Many of us have been feeling some form of burnout since March, and with Thanksgiving quickly approaching and finals looming in the distance, burnout is more likely. It may seem like there is this invisible wall blocking you from being productive — trust me, you’re not alone. So take a deep breath and continue reading for some tips that will help you overcome your burnout.

Wash your sheets. Now, this one might seem a little lame and or boring. And it kind of is, but having clean sheets is like hitting the reset button. It adds to your list of things you were able to accomplish in one day. Do some kind of self-care. This one could relate to a variety of things. Personally, I find it comforting to light candles and listen to Taylor Swift. There are a plethora of options out there to indulge yourself in. This includes baking, napping (my fav), face masks, reading — the list goes on. Drink water. I understand everyone says this one a lot, but it’s an important one! It really does wonders for helping you think better and clearing your skin. There are tons of apps available to remind you to drink water and lots of cute water bottles out there to motivate you. Have a fun day. Think of this as a chance to recharge. Go for a walk and get some vitamin D. With our eyes glued to screens more than ever, it is important to go outside and breathe. Chances are you will feel much better and more refreshed. Online streaming services came in clutch this year. Since we are staying home more often, Netflix, Youtube, etc. has really saved us. This tip is more so a chance for you to watch something with your friends or family. I usually watch shows by myself on my laptop, which can get a little lonely. So grab your cup of water and watch a movie with your parents or your siblings. Or, better yet, introduce David Dobrik’s vlogs to your family and see how they react (my mom has the biggest crush on David now). Having a sense of togetherness is really important during this time. Plan out your schedule. Now that we are closing in on the end of this semester, assignments are piling up and it can be overwhelming. Try to realistically plan out what you can get down in the following weeks. Don’t overexert yourself. It’s okay to take an excused absence here and there to mentally refresh. Find some new music or a podcast. Music will carry you to the finish line. Whatever your musical tastes may be, try to find some new ones to inspire you and your productivity. Podcasts are also a great form of escapism. Listening to other people’s problems and stories is a great way to escape your own thoughts, and you may return with a new perspective.

Burnt out
By: Rory Hanratty
Tags: Mental Health, Burnout

It’s horrible and insidious, and the words carry a crushing weight that describes what it does to you.

Whatever light you had inside get’s smothered until it’s almost gone, you don’t see it coming, but you know it’s there.

A gathering, creeping, clawing shadow.

It makes you doubt yourself, it makes you point the blame elsewhere.

I’m just tired.

It was a long week.

It was only delayed two hours this time.

It makes you see hope where it might not even exist.

It’s not so bad.

It could be worse.

Next week will be better.

Slowly, slowly it changes the texture of things. Everything.

It’s voice whisper in a deadline, an ugly truth in an email, an overheard lie in a conversation.

It constricts you relentlessly and unexpectedly.

I left my headphones in the office.

I need to stay another night.

Sorry, i’ll not be there for your birthday this year.

How was the school play?

It creates its own gravity, drawing in the things that feed it, casting its torturous pall over whatever it touches.

You touch.

You know what light and lightness you had is being eroded.

Effort is monumental.

Every video call is climbing out of a pit.

10 minutes sitting in a car park telling yourself to just move.

Every notification another roll of the dice.

Despite it’s darkness it’s invisible.

Mostly.

“Man you look exhausted”

“You seem a bit off”

“What do you mean you don’t want to come out? C’mon!?”

Then it’s normal.

But it isn’t.

You’re surrounded by it, trapped in it and unable to see how to get out.

You have small moments to push the dark out, create a small space in it.

A pint. Two pints. Three pints.

You see hope that isn’t there, and when it doesn’t push away the dark, the dark somehow get’s thicker. So you chase the the hope again. Again.

You focus on the things that stop you thinking. You act. You do. You do over.

Responsibilities become life or death, goals are imperatives, problems are body blows, you become tied up in the hopelessness and the failure.

Anger and rage follow.

Small issues explode into catastrophic nightmares.

Doors get punched.

Chairs get flung.

You find yourself dropped to the floor, unable to breath.

You need to change. You have to.

I’ll get out. I’ll go somewhere else. You build a plan. You’ll make some changes.

What if it’s the same? What if you can’t?

Its voice is yours now.

So you don’t do anything.

You look for hope that isn’t there.

The density increases.

You go on holiday.

It goes with you. After a few days its effect is diminished.

You don’t even realise it but you’re free.

You feel better.

It’s fine.

Until it isn’t.

You don’t have your own time anymore. Your world is responsibilities, obligations, tasks,

It whispers again. But its voice is your friends, your family, your kids.

‘What are you up to man, we’ve not seen you in ages? <nothing im worthless, i’ll just bring you down>” “Will you put down the fucking phone <this is important. i think. its not. fuck you>” “Are you back early this week?<>”

The effort increases, its density and gravity pull you down further and further.

Constantly.
An abusive society
By: Anna Clark
Tags: Suffering, Burnout, Abusive Relationships, Toxic Workculture, Workplace

I came across an article this week that I found terrible (1). It is an interview with Anna Roy, a liberal and hospital midwife who tells that, due to a lack of means and the deterioration of working conditions, she is “abusive” towards her patients.

On November 11th, she publishes her story on Instagram: she recounts a night of intense and chaotic work, where she was forced to make choices between the different women giving birth, and it is dreadful.

She receives thousands of reactions and comments and decides to create a hashtag #Jesuismaltraitante (#Iamabusive) and she receives many testimonies from other professions (firefighters, policemen, unemployment agency counsellors etc.) who consider themselves as abusive.

This article made me think a lot because it reveals in all its splendor the absurdity of our system, and shows how structural it is. In what world do we give people a job without the means or the conditions to do it properly? Why are people not allowed to work with dignity?

And the observation is irrevocable, it is the same everywhere, in the name of the sacrosanct “productivity” which means nothing. And it is even worse in professions with a high social value but less financial value (teachers, nurses, firemen, social educators, etc.). They find themselves exercising their profession with insufficient means.

The result? A lot of suffering, burnouts, suicides, and a working world where employees are at the end of their capacities. All of this will soon explode because people can’t take it anymore. No matter how much they protest, require to get the means to do their job properly, deplore their working conditions, no one seems to listen.

What seems even more absurd to me is that it would be much cheaper (socially, humanely, ethically) to give people the means to work in good conditions. Asking people: what would you need, what means would you need, to do this or that task? Ask HR: given the amount of work, how many people would we need?

Because what is happening now is that work and its organization are conditioned by financial imperatives, rather than by the needs of the people who do it. Humans are thus being crushed into unsustainable productivity, which has vast consequences for society as a whole. While offering dignified conditions (and therefore sufficient means) would allow us to earn a lot of money in terms of sick leaves, withdrawals and even productivity.

I hope that the current changes in the working world will lead us to reflect on the fruitful modalities of work well done, with healthy and fulfilled employees. Why not make the stock market value conditional on a company’s ethics and the well-being of its employees? Things have to change quickly, otherwise everything will soon explode.

How to Avoid Burnout: A Developer’s Perspective
By: Chad Blais
Tags: Work Life Balance, Burnout, Wellness, Workplace, Engineering

Burnout is one of the most pressing issues developers face, so why don’t we hear about it more? In the tech field, there is an ever-increasing pressure to work harder and smarter than anyone else — but this can come at a cost. A recent survey found that of 11,000 tech workers, 60% felt they were suffering from burnout. Here at iTech Media we are trying to break the stigma by continuing open and honest discussions around mental health. But first things first, what even is burnout?

What is burnout?

Helpguide.org defines burnout as, “a state of emotional, physical, and mental exhaustion caused by excessive and prolonged stress. It occurs when you feel overwhelmed, emotionally drained, and unable to meet constant demands. As the stress continues, you begin to lose the interest and motivation that led you to take on a certain role in the first place.”

For developers like me this stress comes in many forms. As the to-do list grows and deadlines come (and go), the pressure builds from multiple fronts. Over time it becomes overwhelming and you may even begin to care less about quality and more about relieving some of the pressure being exerted onto you. You push code that you know will need to be fixed later. You begin to dread the project and just want it to be done already. This is what the road to burnout looks like…

Symptoms and signs of burnout
Stop Writing About Stuff That Doesn’t Excite You

Win the most games possible

As a football coach, one of my goals is simple; I want to win the most games possible. That means there are two things that I can’t do.

Sacrifice future wins for wins now. Sacrifice wins now for wins in the future.

As a writer, it is not about winning games. As a writer, my goal is to have the most people possible read (and hopefully be helped by) my writing.

Clickbait titles and writing about trendy topics might maximize your reads in the short term. However, it is at the expense of future reads.

If you disappoint a reader enough times with clickbait or poorly written articles, he or she won’t read your work in the future.

Writing about topics that genuinely interest you will help you “win the most games possible” for two reasons.

1. You write better from the heart

“Don’t write what you know — what you know may bore you, and thus bore your readers. Write about what interests you — and interests you deeply — and your readers will catch fire at your words.”

Valerie Sherwood

You do not write as well when your heart isn’t into it. You may not notice, but your readers do. Readers can tell when your heart isn't into it.

Writing about things that you find exciting will raise the quality of your work significantly. Authenticity bleeds through into your writing, and you will naturally put more effort into research when you are interested in the topic.

Another advantage of writing about interesting things is that it will be more enjoyable and potentially teach you something. If the process of writing is both enjoyable and educational is impossible to fail.

You might fail in a monetary sense. However, you will win in the long term. Every article that teaches you something new will help you win later because you can use that newfound knowledge in the future.

2. It helps boost productivity

Assuming that your goal is to have your writing read by the most people possible, you should write as much as you can while still avoiding two things:

Lowering the quality of your writing Burning out

Focusing on exciting topics will help you be more productive by avoiding those two common pitfalls.

Writing about something you like makes it significantly less likely that you will mail it in and write something low quality.

It will also allow you to write more before reaching the point of burn out.
Burnout — Signs, Symptoms, and 10 Things for Prevention and Recovery
By: Renuka Dhinakaran
Tags: Health, Mental Health, Burnout, Symptoms, Burnout Prevention

When I look back, I had each of these symptoms from as early as December 2015, when I was admitted in the middle of winter with dehydration. In 2016, I was running on fumes as we bought our new home, sent our son to school and my practice was exploding. I had gallstone attacks, digestion issues, weight gain, and sleep disturbances. In 2017, one day, I choked on my food and couldn’t eat anything for 12 days and no proper solids for 3 months. I ended up losing 15 kilos.

I still didn’t stop and kept on working, as though to prove a point. In fact, I took on my son’s school’s PTA President job, as though I didn’t have enough on my plate, and helped organize the massive school Halloween party!

In February 2018, I ran from my hotel room in Bonn to the reception to get an ambulance. I was in an ER with an oxygen tube stuck to my nose for half a night. I came back home to be diagnosed with cluster headaches.

In October 2018, I was in a hotel room in London, with my heart rate 120 and palpitations all night. I came back home to be diagnosed with high blood pressure and anxiety. I didn’t listen to any of these!

In April 2019, I crashed and burned in style. I had a hypertensive crisis on top of a mountain on the third day of our vacation. It has been 19 months and I still haven’t recovered. I have, however, learned to listen to my body and just rest when it asks me to.

My therapist recently told me that it takes as long as you got into the state of burnout to get out of it. I’ve been burning out since December 2015 and did not really acknowledge it completely until October 2019. I definitely didn’t do anything concrete about it until September 2020. So by that standard, I have about 5 more years until I recover. I don’t know if I have the patience but I know that I need it and that is a start!

FINAL THOUGHTS

So the first part of this post has been based on experience, while the second part is a combination of experience, research, and hope. Acknowledgment is the beginning of burnout recovery. Time is the secret weapon.

I missed each of these signs, did not take any of these steps until it was far too late. I hope you will not be like me and prevent burnout or get help at the right time. I am now slowly building myself up to recover from a terrible burnout. While I am not well enough to return to practicing law, I have definitely made tremendous leaps in terms of trusting my body and mind. I hope this helps you as much as it has helped me!

Burnout: Worse as a Writer or at a 9–5 Job?

Burnout — Photo by Andrea Piacquadio from Pexels

Many people try to achieve more by working longer hours. And they try to get more done by cramming more obligations into their day. But, by stuffing their days with meetings and commitments, their productivity declines.

They experience burnout.

According to the Mayo Clinic,

“Burnout is a state of physical and emotional exhaustion, that also involves a sense of reduced accomplishment”

Anyone who has been working for a few years has likely experienced burnout. And I’m sure you’ve likely experienced it too.

And when this happens, you seem unable to make progress on your work. You cannot concentrate on writing the article. You no longer have the motivation to finish the report.

But burnout is not permanent. You can take action and improve your situation, as we will see in this article.

The Book On Burnout — Overview. What if taking care of the planet and…
By: Kasey Dreier, Kd
Tags: Climate Justice, Burnout, Stress Management, Self Care, Climate Change

What if taking care of the planet and taking care of yourself were two sides of the same coin?

They are.

Climate change is what happens when we overwork the planet. Burnout is what happens when we overwork humans. At the root of both is the same fundamental, faulty, physics-defying assumption.

We can extract energy and resources from our people and our planet, in the pursuit of productivity and profits, without adequate restoration and regeneration.

If we tackle climate change and stress at this intersecting root cause, we cannot only dispel this egregious myth, we can create a healthier planet and people at the same time!

In Burnout, KD pulls from her experience as a Stanford environmental engineer, sustainability manager for a Fortune 500 company, and a burnout prevention consultant for Salesforce and Kaiser Permanente. She creatively weaves accessible science, relatable stories, and practical tools into fun frameworks that will change the way you experience stress and look at environmentalism.

KD offers simple, analog frameworks that return a sense of agency and ability to impact these behemoth and urgent challenges in a deeply personal way. The three key frameworks are:

The 3 R’s: Recognize, Relive, and Reduce The 3 B’s: Breath, Body, Brain The B.O.S.S.S. Strategy: Boundaries, Ownership, Support, Self-compassion, and Service.

Part book, part workbook, Burnout facilitates an interactive experience on how to actionably reduce stress and meaningfully impact climate justice.

Object Oriented Programming(OOPs concept) for beginners:
By: Sneha Sethi
Tags: Java, Object Oriented, Oops Concepts

Object Oriented Programming is a programming paradigm that organizes a program around its data(that is objects).An object oriented programming uses objects and classes or organising the program around its data effectively.But the question is how it manages its data?What is the approach to manage the code and data?And why is this so popular? And the answer is an Object Oriented Programming paradigm implements these concepts Polymorphism,Inheritance,Abstraction and Encapsulation.But before going to OOPs concepts we need to know more about classes and objects.

Object Oriented Programming Model

Classes and Objects:

Class is a blueprint from which objects are created.Basically a class defines the structure and behaviour of data and code that is shared by a set of objects.

An Object can be any physical entity or you can say things you can see or feel like pen,paper,car etc all are objects.But what is an object in java? In java objects are called instances of class.An object is a physical entity whereas class is a logical entity.For now you can think of a Class defines a new data type which can be used for creating objects of that type.

In real world objects have some state and behaviour. Eg. dog - A dog has some attributes such as breed,color and also has some certain behavioural aspects such as sleep,breathe etc.object consists of :

1. Identity- Object declared by a unique name by which it interacts with other objects.

2. State- State represents the attributes of the object.

3. Behaviours- Behaviour represents the methods used by the object.
Object-Oriented Programming (for Beginners)
By: Krishnkant Jaiswal
Tags: Opps, Object Oriented, Opp

Before directly jumping into Object-Oriented Programming(OPP) one should first understand “What is Object?”. Just look around you. whatever you see or sense or feel everything is an Object. Every object has its own set of features and functions. Using this Object as a concept and implementing it using any programming language is called object-oriented programming.

Four pillars of OPP

Since now we know that what is an object and what is Object-oriented programming. Let's see the four properties that every OPP must-have.

Encapsulation

Encapsulation means putting things in a single capsule(or Box) and treating this capsule as a single unit. Object-oriented programming has the property that all the features and functions of an object are inside the object and we treat this object as a single unit.

Let's take the example of your phone it has many features and functions like make a call, playing songs, playing games, it has its own color, weight, screen size, and many more. All these features and functions belong to your phone but you treat that as a unit, not by a group of features and function this concept is known as Encapsulation.

Abstraction

Abstraction means hiding unnecessary information and showing useful things. Suppose you want to take a selfie on your mobile. What will you do? Just open a camera click on the button and you did you. You don’t know what is going inside your mobile and still, you did what you wanted this concept is known as Abstraction and it is one of the important properties of Object-Oriented Programming.

Polymorphism

Polymorphism means having more than one form. In object-oriented programming, we can use the same function many times with different signatures in that way the same function will be performing different tasks. suppose you want to calculate the area of a triangle or rectangle or circle or hexagon in that case you can use different functions with the same name “area”.

Inheritance

Inheritance means taking some properties and features from someone. There are the following five types of inheritance which we can see in object-oriented programming.

In object-oriented programming, this inheritance feature gives us the power not to write the same thing again and again but simply inherit from someone else if it is already there.

If any programming language has above mentioned 4 properties it will fall into the category of object-oriented programming.

What is polymorphism?
By: Aishwar Muthuraman
Tags: Programming, Software Engineering, Object Oriented, Software Development

What is polymorphism?

It is the ability to substitute one type in place of another.

Why Polymorphism?

This allows us to write code in a generic way. We can write our code against an expected contract without worrying about all the details of an implementation. For e.g. you can write some code against a generic Vehicle type, and others can use it with more specific types (e.g. Car)

It provides more flexibility and reduces code repetition to support similar behavior of different objects.

It allows us to modularize our code better. We can program against a type without having to have a source code dependency on concrete types. This in turn allows the concrete types to be developed independently.

How is Polymorphism achieved?

Using interfaces in languages that support it — where you can program against an interface and at runtime other concrete types can be used in it’s place.

This can be used using inheritance where you can program against a parent type, and at runtime you can pass in other concrete sub types.

Duck typing in languages with a dynamic type system. You can pass any object that contains the expected methods at runtime and the program will use that. This is similar to using interfaces for Polymorphism, except the language does it automatically.

Method overloading is another form of Polymorphism. You can offer the same interface to the consumer of a class, but support different types of input objects.

Java generics offer a form of Polymorphism where data structures and algorithms can be written in a generic way to support various types

What is static vs. dynamic Polymorphism?

Dynamic Polymorphism occurs at runtime where the concrete behavior to use is determined at runtime. An example of this is: invoking a method on an interface in Java, at compile time, the compiler just makes sure the types are compatible. But linking the behavior to execute happens at runtime; the runtime looks at the concrete type it receives and links the interface method call to the corresponding method call in the concrete type

Static Polymorphism occurs at compile time where the concrete behavior to use is determined at compile time. An example of this is method overloading in Java; the compiler knows which variant of a method to invoke at compile time

What’s Wrong with Classes in JavaScript?
By: Fernando Doglio
Tags: Programming, JavaScript, Object Oriented, Web Development, Software Development

What’s missing from JavaScript’s OOP model then?

If our current OOP model is so thin and barely anything more than a layer of abstraction over prototypal inheritance, what exactly are we missing? What could make JS truly OOP?

A good way of looking at this question is to just look at what TypeScript is doing. The team behind that language is definitely pushing JavaScript to the limits by creating something that can be translated into JS. This in turn, is also limiting their capabilities, but a good way to start our OOP wishlist would be to look at their OOP-related features:

There is one caveat that you’ll notice in a second: some of the missing OOP constructs in JavaScript right now, have an intrinsic type-checking functionality that has no real meaning inside a dynamically typed language, which is probably why they haven’t been added yet.

Interfaces

These are great constructs to help define the API a class should comply with. One of the main benefits of interfaces, that would be lost inside typeless JS, is the fact that you could define a variable of any class implementing the same interface and safely call any of its methods.

This can’t be done in plain JS

You can definitely achieve the same thing with a class defining the speak method, and then overwriting it. But then again, you can also do that in any other strongly OOP language. Interfaces are cleaner and more elegant.

Abstract classes

I definitely do miss abstract classes from JS whenever I try to go full OOP with my code. An abstract class is one that defines and implements methods, but that will never be instantiated. It is a way of grouping common behavior that can be extended but never directly used. It’s a great resource and it’s definitely something that could be implemented within the current realm of JS without breaking too much.

Static polymorphism

I personally liked this one from my OOP days, and sometimes feel like it would come in handy if we had it supported in JS as well. Static polymorphism allows us to have the same method defined several times within the same class, but with different signatures. In other words, have the name repeated but make sure it receives different parameters. We have rest parameters now with JS, and this allows us to have an arbitrary number, however, it also means we have to add extra code to our method to handle this level of dynamism. If instead, we could differentiate method signatures more clearly, we would be able to directly encapsulate different flavors of the same behavior into different methods.
Object-Oriented Programming wasn’t a failure; it just takes finesse to wield
By: Jeffrey Bakker

..in building out automation infrastructure for your product, sometimes you don’t really want to think of OOP and objects…

Around 20 years ago, my college instructor for my C++ courses had said that if you can learn C++ at the level he’s teaching, you can program in any language because no language is harder. I’m not the authority on whether he was right on that, but 10 more languages later, I haven’t proven him wrong.

In many peoples’ eyes, C++ was the epitome of Object-Oriented Programming languages. Of course, there might still be some Objective-C purists that would say Objective-C was a better OO approach, as it only added 6 keywords to the ~30-keyword ANSI C language, while taking lessons from Smalltalk. Ask the right C programmer and they’ll say you can do OOP with structs.

There are many kinds of OOP languages, but C-based languages are what I can speak most intelligently about. If you want to do it in Perl, knock yourself out. I can speak only briefly on interpreted languages with good OOP support like Python and Ruby, but with some exceptions, these languages served me better as tools to write function-driven scripts with. For example, in building out automation infrastructure for your product, sometimes you don’t really want to think of OOP and objects; you just want reusable functions to get the job done.

Pure OOP languages, like Java, can be nice in many ways and have brought a lot to the table, but there was always something stopping me from loving Java. I’ll never give it the same praise that I’ve come to respect C# for in its syntactic sugar and in ageing so gracefully as a modern language. Languages like these are great if you’re all-in on OOP. Conversely, some languages (like Dart), which its followers may emphasize support for both OOP and FP, allow you to choose which paradigm is right for the task at hand.
What is an Object? — asked school student
By: Bahaddin Ahmadov
Tags: Java, Object Oriented, Objects, Programming

If you know How Java Code is implemented or have read my previous article “How Java works?” we can go on…

Previous article link : https://ahmadovba.medium.com/how-java-works-asked-5-years-old-9465f663c751

This article covers following:

What is main function? What is Object? What is static?

Lets create new project and name it “human” :

I will give an anatomical example:

When the human is firstly created, at the very beginning of creation, some organ should be the first. This is heart. Lets create a Human and lets create its first organ :

We created our digital human. and it has a heart now. But something is missing. In order to become “live” it has to start pomp and launch its way. Lets do this.

We created main() method and this means the Heart is “live” now, a human has a soul and started its journey. (Dont mention the main function in Brain. we just began to create a human)

OK, time is going and only one organ is not enough for us, we need eyes, brain, liver, lung, ears and so on. lets create them physically in body.

Is there any connection between these organs? Definitely yes.

Our heart beats — so main() function has already been called. Heart beats and it has a function which pumps a blood to eyes, liver and ears for their working. After couple of time Ears are available for listening. After couple of time Eyes can see After couple of time Liver can enzyme

All of these organs have Characteristics and functions.

So ears have:

quantity (character) color (character) hear() (action)

Lets create a Brain and add it its necessary function — signal sending. Because heart doesnt tell the eyes to see.

Ok, We successfully run program. And we got the result “ I see” and “I Hear”.

We came to most confusing part :) Objects.

We run out program for one human. Hmm, But as you pay attention every humans the same characteristic — Seeing, hearing, Color of eyes and so on.

But — everyone is somehow is unique — so — everyone has different eye color, different size of heart, different listening ability. So if we make for everyone different class, so then we would be need 100000000s of classes. But the concept, the draft is the same — Seeing, hearing, Color of eyes, two legs, 2 arms and etc.

Now we begin Object part :)

As you paid attention — we used Public static everywhere. (Forget about “public” for now, and pay fully attention to “static”)

If the variable is NOT static it means this variable can be different by person. So if we say :

means that we only created one person and we can give one characteristics to its organs.

We already declared that human can have ear, eyes, heart, brain and their characteristics and functions. Now we remove static wording and creating direct humans. Lets combine all characteristics in one class named Human.

Now I rename the Heart.class to Main.class. Just for fun :)
The story of NeXTSTEP
By: Pieter Herman
Tags: Operating Systems, Apple, Object Oriented, Nextstep

NEXTSTEP logo

NeXTSTEP an object-oriented, multitasking operating system created by NeXT Computer, Inc. a company founded in 1985 by Apple Computer co-founder Steve Jobs.

The NeXTSTEP 3.3 Desktop.

NeXTSTEP was created on the base of Mach microkernel and BSD Unix system code. NeXTStep was oriented to work in a graphical environment. It had a very well-prepared, intuitive user interface, based on object-oriented architecture, quite different from both the most popular then Microsoft Windows 3.1 and Mac OS.

A Brief Tour of NeXTSTEP — Software Showcase

The core operating system, application execution model, and application framework that was created at NeXT in 1989–1992 is still alive and well inside macOS.

Steve Jobs demoing the NEXT operating system. Many of the features shown here are now in macOS.

The NeXT Computer was launched in October 1988 at a lavish invitation-only event, “NeXT Introduction — the Introduction to the NeXT Generation of Computers for Education” at the Louise M. Davies Symphony Hall in San Francisco, California. The next day, selected educators and software developers were invited to attend for a $100 registration fee the first public technical overview of the NeXT computer at an event called “The NeXT Day” at the San Francisco Hilton. It gave those interested in developing NeXT software an insight into the system’s software architecture and object-oriented programming. Steve Jobs was the luncheon’s speaker.

During the first NeXTWORLD Expo, Steve Jobs previewed NeXTSTEP 3.0 and some hardware. Date: January 22, 1992 Location: San Francisco Civic Center, San Francisco Steve was 37 years old.

NeXT shipped at least a dozen major versions of NeXTSTEP and OPENSTEP for various platforms between 1988–97; below are a few of the most notable:

NeXTSTEP 0.8 (1988): The first version to ship with NeXT hardware, included with the NeXT Computer.

NeXTSTEP 2.0 (1990): This release introduced support for color graphics, floppy disks, CD-ROM, the first appearance of Terminal.app, and more.

NeXTSTEP 3.1 (1993): The first release to support x86 processors, allowing NeXTSTEP to be installed on generic IBM PC-compatible hardware.

NeXTSTEP 3.3 (1995): The last version before the OPENSTEP rename. It supported the Motorola 68K, Intel i386, PA-RISC, and SPARC platforms.

OPENSTEP 4.2 (1996): The final version in development before Apple bought NeXT.

In February 1997, after the purchase of NeXT by Apple, it became the source of the popular operating systems macOS, iOS, watchOS, and tvOS.

Try to find a bug in this small Python code. You will be surprised!
By: Timur Bakibayev

Investigation

First, it would be much more interesting for you to analyze the code above, and find out the problem on your own.

Our printer is a recursive function that outputs the name of a given node with some indentation, then calls itself for its children, indented a little more. There is no problem with this function, and it works 100% correctly.

Is there a problem with creating the Nodes?

No, we create the first node as a root without a parent (how sad), and then we create two children for the root, following by 5 children for each of them.

So, the problem is somewhere else. And it is only the Class definition left.

Let’s take one child and see what is in:

print(node25)

#output: 2-5

That’s fine.

print(node25.parent)

#output: 2

That’s also fine. But what about the parent of the parent? Hmm…

print(node25.parent.parent)

#output: root

That is also ok. Let’s check the children.

print(node25.children)

#output: [<__main__.Node object at 0x7fb443dce750>, <__main__.Node object at 0x7fb443dcec10>, <__main__.Node object at 0x7fb443dced50>, <__main__.Node object at 0x7fb443dcec90>, <__main__.Node object at 0x7fb443dced90>, <__main__.Node object at 0x7fb443dcea10>, <__main__.Node object at 0x7fb443ad4290>, <__main__.Node object at 0x7fb443ad40d0>, <__main__.Node object at 0x7fb443ad4210>, <__main__.Node object at 0x7fb443ad4150>, <__main__.Node object at 0x7fb443dcef50>, <__main__.Node object at 0x7fb443ad4110>]

What?! How many children are there?

print(len(node25.children))

#output: 12

Well… we can see two problems here.

The first problem is that our list looks weird. Of course, this is more important :)

To fix that, simply change “__str__” to “__repr__”. This is strange though. When we print out a single Node, it uses the “__str__” function, and in a list, it uses the “__repr__”. Why, Python?

Ok, and the second problem (the main one) is that Node25 has way too many children. Let’s print them out again, now with the “__repr__” function:

print(node25.children)

#output: [1, 1-1, 1-2, 1-3, 1-4, 1-5, 2, 2-1, 2-2, 2-3, 2-4, 2-5]

Wow, all nodes except the Root are the children of Node25!

Ok, what about the other node?

print(node21.children)

#output: [1, 1-1, 1-2, 1-3, 1-4, 1-5, 2, 2-1, 2-2, 2-3, 2-4, 2-5]

Hm…

print(root.children)

#output: [1, 1-1, 1-2, 1-3, 1-4, 1-5, 2, 2-1, 2-2, 2-3, 2-4, 2-5]

Now the problem is clear — they all share their children.

And here is the reason:
Typescript: Are “Private” properties private?
By: Tuan Le Cong
Tags: Programming, JavaScript, Object Oriented, Tips, Typescript

If you are reading this article, I guess you are interested in the Typescript language. Either you are a newbie or an experienced developer in Typescript language, I bet you use the concept private for class properties many times. But do you know that it is not private at all. Let’s discover together.

Take a look at an example where I have a Student class:

As you can see there are two private properties in the class: attribute phone and method playGame() and we expect that the outside of the class cannot call these properties. And yes, the Typescript compiler guarantees the rule for us.

In the index.js I import the class and I try to violate the rule:

With the modern IDEs and useful plugins, developers can be alerted if they do like this. How luckily we are, right!

But, even you use a simple text editor to write these lines of code. The Typescript compiler will throw errors when building:

You can see the error messages. So, are we safe? The answer is NOT YET. Unfortunately, Typescript only alerts us during compile time, after that, the compiled result is javascript where these private properties will be fully accessible and visible. Let see how:

So, I can violate the rule by cast the Student instance as any and this is the compiled result:

Then, in runtime, it works. Of course, use any is a bad practice or even a mistake. My point here is to prove that we can call private properties in runtime from outside of the class as we have known about Javascript.

But you can have real private properties

With private lass fields. We can easily achieve real private properties. There is however a stage 3 proposal to allow defining private class fields using a hash # prefix. I will modify the class Student as below:

You can see now, the attribute phone is changed to #phone and the method playGame() is changed to #playGame . I keep the same main file with the trick student as any and you can see the result when compiling the code:

The compiler throws an error and the compiling process is exited at the first line of code that the rule is violated. We can see it is more restricted than before where it throws errors for all of the violated lines of code.

You can check more examples in private class fields documentation.
Enums (Enumeration Objects) in Python
Tags: Enum, Object Oriented, Enumeration, Oop, Python

Let's say you are a pokémon developer in 1997 and you have to develop the first Pokémon Edition Yellow Edition. You have already created the basic Pokémon class and also the subtypes like AQUA, FIRE and GRASS, which inherit from the base Pokémon class, are ready.

Let´s see how we could do that without using enumerations and why this is bad!

Photo by Elias Castillo on Unsplash

Now, you want to create a Squirtle! You know Squirtle ? I hope you do!

Note that the following class is a simplyfied example in order to show the necessity of enum objects …

class Squirtle(AquaPokemon):

def __init__(self, name, level):

self.name = name

self.level = level

self.type = "AQUA"

You see the self.type = “Aqua” ? We could do that. Like this, we defined that Squirtle is an AQUA Pokemon, which clearly is true.

Now imagine the following. You have 100 AQUA-Pokemon! Each one of them is designed like Squirtle. Now, your boss tells you:

“Hey dude, I don´t like the name AQUA anymore…. Let´s call it water!” ;)

Hell, no. Now you need to change every class. You need to go to every Pokemon file, check wether it is an Aqua Pokemon and Change it manually. Wish that life could be easier … but … wait a minute! It can!

Enumerations

from enum import Enum # built-in library from pthon class PokeType(Enum):

AQUA = 0

FIRE = 1

GRASS = 2

Thats it! Since Python is not a strong typed language like Java or C#, we need to import the Enum object and pass it to our class (we inherit it) in order to make our class behave like an Enum.

# let´s play a little bit to understand the enum

a = Poketype(1)

>> a

>> <PokeType.Fire: 1>

>> a.value

>> 'FIRE'

>> a.name

>> 1

So we can assign each variable or class our enumeration type and this variable or class gets the attributes of the enum type by name or value.

How would our Squirtle class look like with the Enum Type?

import PokeType

class Squirtle(AquaPokemon):

def __init__(self, name, level):

self.name = name

self.level = level

self.type = PokeType(0)

If we keep going on by doing type assignments in this way, we can easily change Pokemon AQUA to WATER without much effort. Furthermore, our code is so much cleaner now, since we do not depend on a hard coded string (“Aqua”), right?

When should i use an Enum?

Use Enum when you need a predefined list of values which do represent some kind of numeric or textual data. Especially when you want to define a variable/class that can only take one out of a small set of possible values.

Example:

In Machine Learning, if you trained a Neural Network to identify multiple classes for Natural Language Processing, you will need to transform text-lables into integers. Use an Enum in production to predict and automatically transform the integer to your predicted class!

Java & Lombok, a tale of two islands

This is the first in a two-part series on spicing up Java with Lombok.

Java has been with us for more than 25 years. In 2020, it is still relevant and a great language to have under your belt as a programmer. As beautiful as it is though, there is also a lot of criticism.

Especially, Java is considered to be quite verbose. Why do we have to write getters and setters? And what’s up with equals() and hashCode() anyway?

This is where project Lombok comes in.

Object-Oriented Programming

In this article, we will see what does Object-Oriented Programming — abbr. OOP- means. Many times, we see it in action but do we really know what it actually implies for? Let’s jump right in.

Everything we see around is basically an object and OOP is a model that assumes everything is, well, an “object”.

Maybe these objects have similar properties. But they are completely different objects and they have their own actions. There are behaviors we expect from every object.

So we wrote the objects with properties and methods and explain each one as a schema. We call these schemas a Class.

An object is a real form of class. We can produce a lot of different objects by using variants of properties.

We understood the object and class differences. And now we will see how can create an object using classes.

First of all, we using new Classname words to create a new object by using this class name. In summary, we say create me an object of this class. Then we set this object to a variable. Finally, we have an object and now we can set properties to this object. — I’ll explain why I use this way to set the properties to the object in the future encapsulation article. —We can call the object methods the same as setting the properties.

Why we use empty brackets after the new iPhone words? It’s called an Empty Constructor.

If I want to set my values to the first step, we call this way as a Parameterized Constructor.
[TIL-3] SOLID Principles, Explanation and Example
Tags: Java, Solid Principles, Principles Of Design, Principles, Object Oriented

During my performance review at my current company I got a suggestion from my lead that I need to read about SOLID principles. Back then I only skimmed about SOLID principles and just thought that it’s good to know about that and not go through the details.

Lately during my spare time, I’m reading linkedin posts at my linkedin’s feed. Some people post job vacancies and some of them demand solid understanding about SOLID Principles as their minimum qualification.

Therefore I interested to know deeper about that, and compile it to this article.
