How to Create Multiple Worksheets From a List of Column Values and Delete Any Empty Columns Automatically Using R and VBA

2. Delete Any Empty Columns

Once the data frames are created, we can now check if there are any empty columns. First, we should put all the data frames into a list, so we can apply a function over a list (function to all the data frames at once). The below function will get rid of the columns with only na, null, no info and 0. After this, we can unzip the data frames and verify the number of columns- whether the empty columns are correctly deleted or not.

lst<- mget(ls(pattern='^demo')) # putting 'demo' dataframes into a list output <- lapply(lst, function(df) Filter(function(x)!all(is.na(x) || is.null(x) || x == "" || x == 0),df)) list2env(output,envir=.GlobalEnv)#unzipping the list

Before cleaning the empty columns, there were 1044 columns.

list of data frames before cleaning the empty columns

After cleaning, the number of data frames became 13 to 19 columns.

list of data frames after cleaning the empty columns

clean data frames with no empty columns

when unzipping the list, the clean data frames replace the old ones as shown above.

If you want to remove the empty columns for just a few data frames, you can do it manually by using this code.
An early passion for coding that turned into a $10M initiative

“At eight years old, my father came home with an Apple II computer. On this now antiquated machine, I wrote my first lines of code and so began a lifelong passion. I believe every child should have this same opportunity.” — Aaron Skonnard, CEO of Pluralsight

Educating our youth is one of the most important actions we can take as a global community, which is one of the reasons we launched Pluralsight One, our commitment to create significant social impact by investing 1% of our time, equity, profit and product to improve access to technology education and support technology-driven solutions to the world’s greatest challenges.

We know that equalizing access to technology education creates meaningful economic opportunities. It’s clear there’s a technology skills gap—it starts early and is complex. According to Code.org, in the U.S. alone, only 40% of schools teach computer programming. And while there are currently 500,000 open computing jobs across the country, only 50,000 students graduate with computer science degrees annually.

To help tackle the root of this problem, Pluralsight is joining the likes of Google, Microsoft and Facebook in the $300M Internet Association initiative. Through Pluralsight One, we’re committing $10M in support of K-12 computer science programs in the U.S., with a particular focus on diversity and access to quality education.

How to Keep an Excellent Working Relationship With Yourself

Creative exhaustion will kill your consistency as a writer. Here’s how to avoid it while eliminating the stress from your workday.

Photo by Oleg Ivanov on Unsplash

We sometimes overlook the importance of taking care of ourselves, and we tend to criticize our work mannerisms to the point where it becomes rather stressful. It was just recently that I had a good look at how much my work was taking a toll on both my mental and physical health, realizing that it was time to reassess.

It can be easy to want success, to convince yourself that you’re going to start building your platform even though you’re currently trying to shake an array of bad habits. I was one of those people, and I still struggle with consistency daily, but I try my utmost to just show up.

I used to view self-care as a waste of time because there were so many other work-related tasks or responsibilities I could’ve been doing in the time I spent reading or meditating before bed. That was my first mistake. I was running myself into the ground without so much as a break, and I didn’t even know it until I burnt out again.

Are you tired all the time?

Are you struggling to keep content flowing across all of your platforms or meet those writing goals you set for yourself? I know I am, and I have been for a long time. I was overthinking, stressing myself out about not using my time as wisely as I should, and I wondered why I couldn’t have a single consistent week where I didn’t feel exhausted.

I would go to bed every night feeling like a failure, stressed about the next day before it even began, and I knew I had to give myself the lifestyle change that would make writing easier. I had to learn that taking care of myself is a priority.

It’s time you acknowledge that you can’t keep exhausting yourself

I had to have a tough conversation with myself, detailing all of my real goals, so I could figure out how to achieve them in a timely manner without driving myself crazy. Whenever I begin to feel overwhelmed when a deadline approaches or when I don’t have a productive day, I take the necessary time to calm myself down and take it slow.

Sometimes, we’re so eager to finish the day with an extraordinary amount of things done that we don’t even realize how badly we’re hurting ourselves. Now, the extra twenty-thirty minutes just as I wake up and right as I go to bed make the day that much easier to tackle.

Find your balance, and cut yourself some slack.
Step-By-Step Guide To Push Your First Project On GitHub!!
By: Akash Rajvanshi
Tags: Projects, Git, Code, Github, Repositories

5. Create SSH Key.

Why we use SSH? By using the ssh protocol, we can connect and authenticate to remote servers and services. With ssh keys we can connect to GitHub without supplying our username and password at each visit with the help of passphrase.

In HTTPS method, you will need to fill our username and password at every visit, which will be very inconvenient. Git associates a remote URL with a name and our default remote is usually called “Origin”

1. Generating New ssh key and adding it to a ssh agent.

ssh-keygen -t rsa -b 4096 -C "email"

Note :- Place your email in “double quotes”.

This creates a new ssh key using the provided email as a label.

1.1. For default file Press {{ ENTER }}

/home/{{username_of_pc}}/.ssh/id_rsa: ENTER

1.2. Enter a passphrase.

1.3. Now our identification has been saved in

Private Key : /home/{{username_of_pc}}/.ssh/id_rsa

& Public Key : .ssh/id_rsa.pub

2. Adding our ssh key to the ssh agent

eval "$(ssh-agent -s)"

it gives like {{agent_id : 15800}}

3. Now we add SSH Private key to ssh-agent to our default path.

ssh-add ~/.ssh/id_rsa

4. Adding a new ssh key to your github account.

Copy the ssh key to our clipboard.

Automatic Method (Using Xclip)

On Ubuntu

sudo apt-get install xclip on Manjaro

Open Octopi -> Download Xclip Xclip-set clip <~/.ssh/id_rsa.pub

2. Manual Method

Home/.ssh/id_rsa.pub

Open this file and copy your key.

Now goto github.com ➢➢ Under Profile Photo (Drop Down) ➢➢ Settings ➢➢ Use SideBar {{ SSH & GPG Keys }} ➢➢ Then go to this directory on your computer {{Home/.ssh/id_rsa.pub}}

Open this file and copy your key. Create new SSH key ➢➢ Title the filed with descriptive label ➢➢ Paste key into a “Key Field” ➢➢ Click on {{ Add SSH Key }}

5. Now for Testing SSH Connection.

ssh -T git@github.com

After running this , it will show this messege on terminal!!

a sonnet for fall

In the author’s gardens

This Autumn sun lies lighter than the breeze

That gentled us in Summer’s twilight hour;

The butternuts lie curing in the field,

Absorbing into golden flesh sun’s power.

The whole Earth holds her breath now once again

As we approach the Mabon Equinox,

The harvest deep and rich that feeds us all

And makes of the most rigid heterodox.

Now swathed in mists, in fog of disbelief,

Like windows made opaque by cooling air,

The Autumn sun burns false division off,

Revealing Spirit that was always there.

Such beauty as lights up this nascent Fall

Burns in all creatures, people, things…in all.
In the Midst of His Fears
By: Valentine Nnebe

The lecture room of the University of Mississippi was cold with silence. So still that the drop of a pin could be heard throughout the entire space. All views were focused at one direction.

“I…I mean the cornea… the cornea is transparent because…because…” Keshawn stuttered.

“Yes, continue,” Mrs Higgins nudged him on nodding.

“The cornea is the outer layer of…of”

“C’mon…” The class grew exasperated.

Paper balls of all shapes and sizes landed all over his frame.

“Will you all stop that.” Mrs Higgins yelled at the top of her voice.

Keshawn was in a nightmare, one that was all too familiar. This wasn’t the first or second time such a thing had happened. His only wish was that the ground will break open and take him in, but it didn’t.

He couldn’t imagine a second encounter with these faces staring at him. What would they say at the cafeteria and the locker room? What new joke would they make of him? Should he quit this optometry course? He drifted away in a state of sheer humiliation.

“He’s a stupid idiot. That’s what he is.” Someone mocked, fetching him back to reality.

“He needs to go back to Africa. That’s where idiots like him belong.” Another said.

The whole class bursted into shaming laughter.

“Quiet!” Mrs Higgins instructed, “Now Keshawn I understand you’re anxious, we all are too in situations like this.

But if you must come through this course in flying colours you have to get your act together. You have to prove you’re not the idiot you’ve made of yourself today.”

Keshawn was dumbfounded.

“Idiot?” That word rang endlessly with immense hurt in his mind. Bowing his head low he walked to his seat amidst the chuckling of his classmates.

“Class dismissed,” Mrs Higgins said out loud, “See you all next Wednesday.”

Just in time as the recess bell rang.

Keshawn grabbed his lunchbox, strapped on his bag and sped out the door for the cafeteria which was on the eleventh floor. He made no eye contact as this was one of his worst embarrassments in recent times.

Being a black boy in one of the foremost cities known for racism he had learnt to absorb pain as often as it came.

He knew what it was to be the scumbag and be made the laughingstock. At times he felt he had no choice to bargain as this was his dealing by fate.

He reached the elevator pressing the button; it opened. Four white boys inside discussed among themselves.

“Where are you going?” One asked.

“To the cafeteria,” he responded.

Keshawn took a step forward into the lift, but in a split second one of the boys kicked him out with his right leg.

“Your colour has no place here, can’t you see that?” he jeered at him.

Keshawn fell backwards on the floor spilling his lunch all over his face only to watch the doors of the lift close.

How to Increase Your Freelance Writing Income

Without getting new clients

Photo by Colton Sturgeon on Unsplash

I think most people who go into freelance writing share the same dream.

It’s a dream of being able to wake up without an alarm clock. Of having time for your kids, or traveling the world. A vision of a life without endless zoom meeting and exhausting office politics.

A dream of freedom.

Am I right?

And yet, I’ve met so many freelance writers who struggle. Who are stressed out every time they need to pay their bills, frustrated by low-paying gigs, and sick of content mills and rude clients.

I started Freelancers’ Pharmacy to provide cures for that. Twelve years of freelance writing have taught me what works — and what doesn’t. Over time, I’ve perfected my methods for finding clients, doing the work, and getting paid good money in the process.

I’ve also worked as Head of Marketing at two large international companies (yes, I’ve sometimes ventured over to the dark side :P). So I know both what it’s like to sell freelancing services and what it’s like to buy them.

Today I run a successful 6-figure freelancing business alongside my work as a marketing manager, and thanks to solid groundwork and processes, I actually find the time for both.

The power of upselling

One of the most efficient ways to quickly boost your income is by selling more to the clients you already have.

Since you already have a relationship with the client, the process is super simple. No need for time-consuming introductions or relationship-building. You just shoot them an email or give them a call, offering an additional service that complements your current agreement. If they find it useful (and they will!), you add it to your next invoice. Ka-ching!

How to make more money — with the content you’re already writing

Let’s say your writing a blog post for your customer. Then there are several things you can do to immediately increase the value of your delivery, and thereby your clients willingness to pay more.

To help you out, I’ve created a cheat sheet, outlining 5 (ridiculously simple) ways to add value to your writing and raise your rates.

In this cheat sheet, I share 5 smart ways to make more money — without writing more articles. I’ll show you how to:

Add value to the content you’re writing — without writing more!

Save your clients time and money (they will love you for it!)

People Management
By: Rayhan Muzakki
Tags: People Management

A team consists of multiple of individuals collaborating with each other to achieve the same goal, however these individuals are different from each other with their different ages, profile, customs and their personality.

To manage these differences and to align with the entire team is definitely a challenge and that’s where the importance of managing people.

What is People Management?

People management is the process of training, motivating and directing people in your team, an example would be working as a manager to direct employees. People management is important due to:

Influences productivity by morale and motivation.

If team members know what they should do and what resources are needed to perform their tasks it avoids wasting time with obstacles and motivated with a clear goal thus increasing productivity.

Improved work environment

An individual will go to the workplace in a daily basis and if their work environment is preferable for them this increases their sense of belonging, shows the importance of everyone for the team and how much their work assists in the achievement of their goals. Results in reducing conflicts between team members and motivation to work.

key to a successful project change management

When working in a project there would be changes or errors within the work and so if there is effective people management these changes can be easily shared between members and be dealt with swiftness.

Key Components of People Management

There are 4 key components of an effective people management:

Task Management

When working on a project, tasks will be divided to team members. It would be an inefficient way if you are working on a task that is not suitable for or have less experience with others, thus managing which tasks will be entrusted to team members with more experience would be more beneficial and optimal for them because they are not pressured by their inability.

Teamwork

Effective people management involves understanding the people who make up the team, example are team member’s personalities and their motivations. As a team you must work with each other and trust is needed between each team member thus understanding each other is essential in people management.

Communication

Communication is important for people management because to share information you need talk between team members or use other tools to share information. Thus having a clear and easy to access communication can share information faster and more accurate.

Motivation

Motivated individuals work better and thus having a good moral in the team would be more beneficial in the long run. Leadership plays an essential role in this process by giving team members a clear goal.
Rejuvenation
By: J.A. Taylor
Tags: Short Story, Horror, Fiction, Aging, SciFi

Shelly fastened the supple face onto her cranial mounts and combed the strands of implanted hair over its edges. The past few years had seen a sharp decline in the effectiveness of her rejuvenation treatments. She now had to inject nanofluids each night before sleeping in an anti-gravity capsule just to retain what little skin was left on her skull. It will help with the ‘sag,’ the salesman had said. But her aging body needed more than a reprieve from gravity.

With her skin suit on and her new face applied, she queried her digital assistant. “Projection time?”

“9.7 hours,” the male computer voice echoed from her prep chamber.

“Ugh. What time will it expire?”

“Expiration calculated to occur at 6:23 p.m.” She sighed, but sobs soon followed. Her optical replacements manufactured saline. At least the tears tasted real. She remembered that much. She rubbed a finger across the tip of her artificial nose and pain seared her nasal cavity.

“Break detected,” the computer said. “Repairing.” A robotic arm raised from the counter and began removing her mask.

“Stop. Leave it.” The arm halted, then retracted. “Ring my date. Voice only.”

“Contacting Fleming, voice only,” the assistant announced. A hologram of a dark-haired, handsome man’s bust appeared in the middle of the room. His face remained expressionless, but the image followed her as she rose from her vanity and seated herself on the sofa. Shelly rolled her eyes. Flyboy Fleming, he called himself. A ridiculous alias. The young ones were stupid, but usually handsome.

“Well hullo you,” he answered.

Shelly paused. “I usually don’t make contact prior.”

“Can’t wait, can you?” The arrogance. It had lost any sexiness decades ago.

“You have no idea.”

He offered a mocking laugh.

“Not sure I can wait til seven. How about you come here right at six for something special? We’ll eat once we’re famished.”

“Your place? Wooooot! I’m in. Shoot me the hex point and door code. I’ll be there.”

“Sure you won’t regret it?” she asked playfully.

“You don’t scare me,” he answered.

“We’ll see… you at six sharp, flyboy.” She waved a hand, ending the call.

“Send location and grant access to Fleming. Allow entry today, near 6 p.m.”

“Done,” the computer voice answered.

“Resume repair,” she said. The robotic arm went to work on her nose.
Hitler’s 1936 Olympics Dazzled International Audiences
By: Sean Kernan
Tags: Life Lessons, Politics, Life, History, Sports

The opening ceremony and subsequent games succeeded, mostly

There were a number of things that didn’t go to plan. The first was the release of 25,000 doves at the start of the ceremony. After they pulled the latch and the doves dispersed into the air, to the loving screams of the crowds, the Germans shot off a cannon to officially mark the start of the Olympics.

Unfortunately, the shot of that cannon scared all the birds. As a result, thousands of them pooped on the crowds.

Distance runner, Louis Zamperini said:

“They scared the poop out of the pigeons, and we had straw hats, flat straw hats, and you could hear the pitter-patter on our straw hats, but we felt sorry for the women, for they got it in their hair, but I mean there were a mass of droppings, and I say it was so funny.”

This certainly went better than the 1988 Olympic Games when the doves got torched on accident. The doves missed the memo that, when the cauldron is lit, you are supposed to fly away.

The other snafu was the fact that Hitler had pushed his pro-Aryan agenda, yet they still had to watch as Jesse Owens, and another black American athlete, swept the 100m dash and other events. It wasn’t a great look for that old theory of white supremacy.

Hitler was stunned. But, in a bitter twist of irony, he was willing to wave and congratulate Jesse Owens, while US President Roosevelt wouldn’t even host him at the White House for fear of political implications.
7 Things I Learned From My First Software Developer Internship
By: Maria Sitkovets
Tags: Life Lessons, Failure, Tech, Internships, Developer

2. Be empathetic and patient with others

Once I had built trust with my own team, I was given more challenges that were connected across multiple teams. With one of these projects, I was working on creating something that could be published and used by people all across our company. However, this required collaborating with another team in order to get it published into their system

At the time, I didn’t think that it was my project. It wasn’t an idea that I had come up with and there were so many stakeholders and opinions on my code and documentation that it didn’t feel like my work anymore. But that’s not the point. The problem was, I was neglecting my responsibility to communicate with the other team. I just let my project manager do it because he had the connections.

But then, after months of hard work and a lot of writing and re-writing documents, I still had nothing to show for it. Why? Because I had only set up a few meetings with the other team and those never got that far.

However, I can definitely say that this wasn’t entirely my fault. In fact, the other team was even worse. For months they had led me on to believe that they could help me and my team, but every time we asked them questions and booked meetings, they’d send us to a new group of people and we’d have to start all over again. It felt like I was a hot potato being thrown around in circles.

But, once I got annoyed enough with this, I decided that it was time for me to do something about it. So, I booked a meeting with the newest person they had told me to talk to and I learned why I was being treated this way.

It’s not like people want to lie to you and lead you on. It just sometimes happens. What I learned from this person was that their whole team was in an even tougher situation than mine. They were re-organizing everything and everyone. Some projects were being thrown away and others were being prioritized on tight deadlines. Once I learned about that, I stopped being annoyed and all I felt was empathy for the people on that team. Even though they made mistakes and should have communicated the problems they were facing earlier (again, to help build trust), I still had to feel sorry for them.

You have to remember that helping you with your work isn’t the top priority of everyone at your company. People might have other crazier things going on at work or at home that you don’t even know about. All you have to do is ask, and be prepared to be empathetic towards and patient with them.
Do You Still Love Me?
By: Kerry Mcavoy
Tags: Poetry, Relationships, Forgiveness, Love, Kerry Mcavoy

Do you still love me?

There it was —

Hung in the air between us, suspended;

Spoken, the burning question.

Did I still love him?

The weight of the years together pressed in.

Too many lonely conversations,

Too many dangling fights.

A look passed between us.

He longed to unravel the past.

But time stood fixed.

His choices and priorities done.

I’m afraid you won’t be able to forgive me, he said.

And with those words,

The salve of absolution and forgetfulness

Poured over me.

He now lays silent

In the cold grip of endless sleep.

But his parting gift of regret has struck its mark.

Do you still love me?

The wind is now his breath.

There’s a hushed silence,

As creation bends close to hear.

Did I still love him?

A broken heart, time healed;

Remembrances, sorrow sweetened.

My tears answer yes.

Maybe she’s born with it

Yamini Krishnan writes a poem about the plight of femininity in the contemporary patriarchal society.

Image Credit: AP

Maybe she’s born with it,

Or maybe she wakes up every morning to the screech of war horns

and the gongs of her time running out,

Maybe the dark lines that encircle her revolver eyes

and the blood-crimson strokes she draws around her gunshot lips

feel like war paint,

Maybe they put on a show of courage on this battlefield.

Maybe she’s born with it,

Or maybe she looked at herself in the mirror one day,

And saw ridges rising on her forehead, small bumpy hills on the tip of her nose,

Maybe she was never taught how to appreciate the scenery.

Maybe she’s born with it,

Or maybe she was eleven, and it was a summer of cotton shorts and pastel tank tops,

And her sister snatched the football from her small hands,

Said that pretty girls shouldn’t go out into the sun like that,

Told her that the floppy-haired boy who sat behind her in class,

The one who played piano and had eyes the colour of melting ice cream,

Wouldn’t like her if she was too tanned.

Maybe she’s born with it

Or maybe her eyebrows are too curious, ask too many difficult questions,

questions that stand out of place

Questions no one has an answer to,

Maybe she raises her hand in class too often,

Maybe a string shaving off these question marks stretched above her eyes will make her less formidable.

Maybe she’s born with it,

Or maybe she’s sitting at a polished mahogany table at a tea party,

With her mother’s fuchsia smile sketched onto her face,

Her manicured nails grappling with the faint memory

of tennis racket fibre and sandcastle dust.

Maybe she’s born with it,

Or maybe she’s a cracked sculpture,

Concealer putting up a valiant effort to fill in the chasms,

Cherry rouge highlighting hypothetical happiness onto her cheeks,

Powder foundation settled over flesh rotting in misery.

Maybe she’s born with it.

Maybe she isn’t.

Maybe she never wanted to be.

Is SegWit a block size increase?
By: Segwit Resources
Tags: Blockchain, Bitcoin, FAQ

Yes! Segregated witness replaces the block size limit with a new block weight limit, counting each byte of witness data as 1 unit of weight and UTXO transaction data as 4 units; as a result, the maximum size of a block becomes just under 4 MB.

However, blocks are not expected to consist entirely of witness data, so blocks near 4 MB in size would be unlikely.

According to some calculations performed by Anthony Towns, a block filled with standard single-signature P2PKH transactions would be about 1.6 MB and a block filled with 2-of-2 multisignature transactions would be about 2.0 MB. As an example, here is one block mined on the Bitcoin testnet, which currently supports SegWit, containing 1.7MB of transactions.

Even as a coder, when I first heard those terms, I thought, OK so a new node that supports SegWit will download the old, traditional block, and then download the new “witness block” as well, and with both those things be able to verify everything. First day I started coding (re-implementing SegWit in golang from the BIPs without looking at the c++ code) I realized, nope, that’s not how it works. The “witness block” has everything, including witnesses. The new software doesn’t touch non-witness blocks. The blocks are bigger. — Tadge Dryja, MIT DCI

It is further likely that future scaling improvements, such as the Lightning Network and increased used of CoinJoin and other multi-sig constructions will improve the ratio such that filled blocks become larger than 2 MB.
Call for submissions — how do you deal with not feeling seen?
By: Kern Carter
Tags: Art, Writing

As writers and artists, we put so much into our work. We’re literally offering pieces of ourselves to the world in exchange for recognition, appreciation and the opportunity to be seen and heard.

But that doesn’t always happen. Not in the way we hope. As writers, we’ll put out articles no one reads or books no agent or publisher wants to represent. Yet we keep on writing.

In this call for submission, I want you to talk about how you manage to keep going without feeling like you’re being seen or heard. What motivates you to wake up every morning and dedicate your life to your art? How do you react when something you’ve been working on for weeks or months or even years doesn’t get the kind of attention you think it deserves?

Same rules as always:

If you’re already a writer for CRY, go ahead and submit.

If you’re not a writer for CRY but would like to submit to this request, let us know and we’ll add you ASAP.

Be as creative as you want in your submissions. As long as you stick to the topic, we’ll consider it.

Just because you submit doesn’t mean we’ll post. If you haven’t heard back from us in three days, consider that a pass.

Deadline to submit is this Monday, November 2.

5 Reasons Cishet Poly Folks Probably Shouldn’t Claim to Be Queer, Even Though Y’all Really Want To

It Erases Those of Us Who Actually Are Queer

Those of us who are both non-monogamous and queer find ourselves floating around in the background while you folks tend to get the attention. This is a serious problem. It’s not something intentional, we’re sure of it.

It’s just that, in efforts to make non-monogamy more palatable to the masses, it’s much easier to get the idea past filters if the participants are otherwise “normal”. Since media and entertainment work the way they do, it necessarily means that us queers end up with the short end of the stick. Even worse, when you are straight and cis, claiming that your polyamory is queer obfuscates the meaning. It makes people who are queer in every other way less visible. It centers, once again, heteropatriarchal values and experiences.

Being queer and poly is a vastly different experience than being straight and poly.

Did you not realize that our experiences even differ?

Well, keep this in mind…

Much of Cishet Non-Monogamy Has More in Common With Monogamy +

Most straight cis people lead fairly straightforward lives. Or at least, more recognizable lives. You don’t spend your lives fighting against the amatonormative current. Even if you do, there are still many things you’ll never experience as a cis straight person.

For this reason, many of you only have your normative history to draw on. Even if your polyamory is your orientation rather than your choice, your most likely approach often ends up like Frankin Veaux’s in The Game Changer. Years, or even decades of relationships built on the idea of monogamy plus one.

What do I mean by that exactly? Monogamy plus one is the reason the non-monogamous communities even have terms like hierarchy, secondary, tertiary, polyfidelity, etc and the reason particular non-monogamies like Relationship Anarchy, solo polyamory, relationship fluid, and others have appeared as a way to push back against it.

There even exists out there now a “Secondary’s Bill of Relationship Rights”!

I’m not saying that being a secondary or wanting a polyfidelitous relationship is wrong or worse, just that it took so much pain, anguish, jealousy, guilt, and mistakes to get to the point where the community is finally openly discussing how these attitudes can be abusive, divisive, and harmful.

Because much of straight, cis, well-off mono culture is built upon the amatonormative arm of abuse culture in general (more on that in a later post), straight cis people within poly communities tend to repeat the same mistakes, perpetuate the same imbalances, and tread the same ground as people who are monogamous.

But why would that bother queer poly people so much? It’s not like they invented the modern form of polyamory or anything.
Wounds: Past — Present — Future. July 2017:

July 2017:

Things lately have been a bit unsettled in my world. There have been a few changes at my work and also changes in my relationships which have left me licking old wounds. But also have me reacting to My Now with more stress and emotion than is warranted. Throw a scoop of anxiety on all that to fret about what may be coming at me down the road and here we are.

It’s ironic because nothing is really altered in my reality since last week at this time, yet it seems I am looking at the world from a different lens these days.

Is it simply the idea of change that is so disturbing? A mere thought? Perhaps.

Thoughts become things.

If I let go of my old wounds and change the way I deal with relationships in the here and now — will I recognize myself?

Who will I be without the comfort of my scars?

Can I really walk the walk and talk the talk of trusting The Universe with my future?

Vulnerability. Life without shields. The idea is both exhilarating and terrifying.

Namaste.

Addendum: Written nearly 3 years ago — this piece asked me to lay down my shields and TRUST The Universe with My Life. I’m getting there. The roller-coaster ride of 2020 has played hell with this trust. Pain, isolation, suffering, death — All. The. Things. And yet — here we are. Me still writing and you still reading. That in itself is plenty to be thankful for.

May all beings be safe. May all beings be healthy. May all beings be free. May all beings be at peace.

Christl is currently studying Full-stack Web Development Program

Q: Tell us about your background

I am a medical student in the Philippines. I have to attend school from 8 to 5. Sometimes, I have crazy schedules. I am planning to become a neurologist, something to do with the brain.

Q: Why do you want to study coding when you’re a medical student?

For me, coding is like a language. If you understand coding, you can leverage it to get your messages across society.

There’s this book called Hacking Your Education. I learnt that you have to learn 2 things in life: learn how to code and learn how to write. You need to know technology, and you need to know communications.

I found coding very fun because it’s so logical. Learning how to code is like learning about how to think logically and clearly. It’s empowering to have the capacity to understand code, and coding can be tremendously useful in the future.

The future of medicine is also leaning towards tech. You have to write code in many medical studies. You also have to collaborate with engineers.

Q: What do you like about Altcademy?

The best value from Altcademy is the mentorship. I always ask my mentor for help while I am working on challenging projects.

I like the curriculum structure at Altcademy. Structure goes first, and the specifics go after. It’s good to be able to see the big picture and the “why” before digging into the details.

With Altcademy, I’ve learnt the necessary train of thoughts when it comes to coding. You have to be logical and creative at the same time.

The “Aha” moments always happen when I am working on projects and talking to my mentor.

Q: Why did you choose Altcademy?

I am already self-motivated enough to learn. You can actually get a lot of content online for free, but it’s hard to consolidate these content.

I want a curriculum that’s already well consolidated. I also want a program with flexible schedule and mentorship because I have a packed schedule with medical school, and I want to save time.

Altcademy’s online NanoMajors turn out to be quite affordable and flexible!

Q: What’s the next thing for you?

I have just started learning JavaScript. I aim to complete my Full-stack Web Development NanoMajor and finish my medical degree at the same time!
On A Friday: Relationship with God?

People ask me every so often, how my relationship with God is doing. It’s always been a hard question for me to answer. Mainly because just like any relationship, it has its ups and downs, its highs, lows, and round-a-bouts. How can anyone answer that question? If I happen to feel distant from God one day, does it mean that my relationship with God suffers? If I happen to be lazy, gluttonous, or deal with moments of lust would things be “bad” in my relationship with God?

Many people liken a relationship with God, to a relationship with a person, and in many ways it is true. You can talk about stuff, or even better, talk to God out-loud on the subway to freak out people around you, stuff like that.

But in other ways its so different. We’re talking about a relationship to an infinitely unknowable, yet knowable, intangible being who knows my thoughts even before they’ve been thought. How would you like your best friend to know your every next move? It’s not the most comfy of circumstances :) So in a way, yeah it’s different.

The more I grow in life, the more I realize it is impossible for me to be separated from my creator. Impossible. God exists within me, around me, and in my very heart. So at any moment, how is my relationship with God? Is it good or is it bad? I don’t know, but it’s there.

How to Write Code With Your Kids at Home

Are you locked in at home with kids? Here are some tips to help you stay sane, do some work, and still leave a smile on your kids’ faces

Photo by Allen Taylor on Unsplash.

Worst-case scenario: You are alone, your kid is five years old and full of energy, and your company successfully switched to remote working or you are a freelancer already working from home.

Everything would work out fine if your kid could stop storming in every five minutes with a question or request:

I’m hungry.

I’m angry.

I’m lonely.

I need to poo.

Mommy, Daddy, I have a million ideas…

And we all know that interruptions don’t help anyone write code.

To really get anything done, you need at least an hour of quiet time. And with the coronavirus here to stay, what can we do? Things still need to be done. Bugs need to be removed, urgent things need to be handled.

So here are some tips to help you stay sane, write some code, fix some bugs, and still keep your kid happy:

Past — ماضی

Polyglot poetry — Urdu and English

Roman Urdu

Maazi se azaadi paane ki koshish main

kahin apne aap ko peechay chor aae

Ab hum taareekh ke saaye talay

hain wapas apne wajood ko dhoondne niklay

Yeh chupan chupaai

ab humain basar nahi karti

Sooraj dil main liay phirte hain

magar darte hain roshan honey se

English

In the struggle of liberation from the past

we left ourselves somewhere behind

Now, by the guidance of this shadow

we continue our journey, in search of our existence

This hide and seek, does not suit us, anymore

You carry the Sun in your heart

yet remain afraid of being enlightened

Urdu

ماضی سے آزادی پانے کی کوشش میں

کہیں اپنے آپ کو پِیچھے چور آئے

اب ہم تاریخ كے سائے تلے

ہَیں واپس اپنے وجود کو ڈھونڈتے نیکلای

یہ چھپن چوپاای

اب ہمیں بسر نہیں کرتی

سورج دِل میں لیے پھرتے ہَیں

مگر ڈرتے ہَیں روشَن ہنی سے
This Story Transformed My Life
By: Alexa V.S.
Tags: Self Improvement, Life Lessons, Inspiration, This Happened To Me, Writing

Once upon a time, I was a professional “waiter”. If I wanted to write a book, I waited until I felt inspired. If I felt inspired, I waited until I had enough time. If I had enough time, I waited until *insert here whatever excuse you can come up with*.

Excuses ruled my life. I was always too busy to sit in my goddamn chair and write my goddamn book. Instead, I fused with the couch and binge-watched Friends for the tenth time.

I’m young. Life needs to be lived. I’ll have time to write later.

Except, later didn’t exist.

One hour of wasted time became a day. One day became a week. One week became a year. And what did I have to show for it? Nothing.

Fortunately, everything changed in La Cerdaña, a half-French, half-Spanish misty mountain valley. Up to this day, I consider it the most breath-taking place in the world.

Within its idyllic landscapes and delicious cuisine, I had a breakthrough.

One morning, I woke up at dawn. As the sun pierced through a thick layer of mist covering the valley and the surrounding mountains, my chest contracted.

Though I don’t understand why or how, an urge to write — stronger than anything I’d felt before — overtook me. After grabbing a pen, I scribbled a story in my journal.

As I wrote, I didn’t register what words left my soul. I was in a trance, possessed. The story wanted to claim its place in the world. It was a message, a warning.

Once I finished, I read what I’d written — and cried like I hadn’t in a long, long time.

The story was like a punch to the stomach. A reminder of the time I was wasting, of the dreams I wasn’t chasing. A reminder that if I continued as a professional procrastinator, regret would fill my days.

Since then, I’ve written three books. Now, I’m never too busy to sit in my goddamn chair and write my goddamn book.

If I don’t have time, I reschedule my week to create it. If I’m not inspired, I take a walk or listen to goosebump-inducing music to get my creative juices flowing.

If I want to write a book, I do it.

There are off days, of course. Days when I want to crawl under my bed and eat ice cream. Days when my creativity well feels as dry as La Cerdanya’s air.

Days when I’m a step away from quitting.

On those days, I return to the story. Its spirit invigorates me. Its message pushes me to sit and write.

Hopefully, it will inspire you as well.

This Is Not a Love Poem
By: Anna Breslin

This Is Not a Love Poem

A poem

Simultaneous Contrasts: Sun and Moon, Robert Delaunay (public domain)

.

.

This is not a love poem

about a mutually shared

psychosis full of separate

and shared delusions.

This is not a love poem,

or a fairytale co-written

with narratives that compete

and culminate in tragedy

worthy of O. Henry

or Shakespeare.

This NOT A LOVE poem.

L o v e is not the stuff

of rom-coms, the sad poetry

of Lord Byron, or ballads

of bygone eras.

Love is within,

and everything

that sparks it

does so because you

decide to let it.

This is not a love poem.

Love doesn’t need words-

love is in your eyes.

You are the poetry

in the cool autumn breeze

that kisses your cheek.

Love is witness.

If you want a love poem,

breathe,

be.
