Iterating over JavaScript objects declaratively or how to map, filter and reduce on objects
By: Amirali Esmaeili
Tags: JavaScript, Functional Programming, Js, ES6

Photo by chuttersnap on Unsplash

Plain javascript objects are very useful, although ES6 provides Map data structure, it’s still common to use them as key-value structures. But iterating over them its not as easy as using array higher order functions like filter or reduce, what if there exist such functions for js objects too.

Let’s write some of them with the help of Object.entries, folding, spread operator and computed property names (aka dynamic keys).

The idea behind all functions we are going to implement is the same, Object.entries returns an array of [key, value] pairs, we iterate over the array and eventualy build up what we want.

map

It takes an object obj and a functioni fun and returns a new Object with same keys and fun applied on all property values. Implementation is pretty simple , we reduce the array retuned by object entries with initial value of {} and add one property (which is the originial property with fun applied on it) in each step:

in reducer we flatten the previous object (accumulator) and add the new property.

filter

filter implementation is pretty similar to map but in each step instead of adding the fun applied property we will check whether predicate satisfies or not and using ternary we will return current property (inside an object) or an empty object and then using spread … operator we some how flatten ternary result.

reduce

reduce takes three arguments the input object, the reducer function and an initial value.

try to implement fitler and map using implemented reduce function.

Examples

Lets say we have an object of fruits like this:

const fruits = {

apple: {

qty: 300,

color: "green",

name: "apple",

price: 2

},

banana: {

qty: 130,

color: "yellow",

name: "banana",

price: 3

},

orange: {

qty: 120,

color: "orange",

name: "orange",

price: 1.5

},

melon: {

qty: 70,

color: "yellow",

name: "melon",

price: 5

}

};

and want to map them into their colors:

const myFruits = map(fruits, (_, fruit) => fruit.color);

/*

{ apple: 'green',

banana: 'yellow',

orange: 'orange',

melon: 'yellow' }

/*

or filter items with price less than or equal 2:

const myFruits = filter(fruits, (_, fruit) => fruit.price <= 2);

/*

{ apple: { qty: 300, color: 'green', name: 'apple', price: 2 },

orange: { qty: 120, color: 'orange', name: 'orange', price: 1.5 } }

/*

or convert them into an array:

const myFruits = reduce(fruits, (prev, _, fruit) => [...prev, fruit], []);

/*

[ { qty: 300, color: 'green', name: 'apple', price: 2 },

{ qty: 130, color: 'yellow', name: 'banana', price: 3 },

{ qty: 120, color: 'orange', name: 'orange', price: 1.5 },

{ qty: 70, color: 'yellow', name: 'melon', price: 5 } ]

*/

80s Tamil Movie Directors | Bhaskar
By: Sylvian Patrick
Tags: Bhaskar, 80s Tamil Directors, Tamil Movie Directors, Tamil Movies

M Bhaskar graduated from The Presidency College, Chennai and joined as an assistant director to CV Sridhar in 1964. He worked with him until 1975. Most of the websites report that he worked as a second unit director for a Hollywood production produced by 20th Century Fox. It was tough to identify the movie, and I gave up after a search.

Bhaskar, Tamil Movie Director

Although he started his direction career with an innocuous movie titled Innum Oru Meera, his breakthrough came in his second movie when he made a growing actor by the name Rajinikanth as his lead actor. He was impressed with Rajinikanth when he saw him in Aarupushpangal, but none of the actors was ready to play the villain for Rajinikanth. Finally, Srikanth accepted to play the antagonist, and Bhairavi happened. Superstar title for Rajinikanth was first used in this movie.

Post-Bhiaravi, Bhaskar didn’t receive any offers, and so, he produced and directed Soolam under the Oscar Movies banner. Soolam was a masala entertainer that made some real profits and Bhaskar adorned the title of “Soolam” Bhaskar. He made more than 20 movies in Tamil, Hindi and Telugu. He continued to produce and direct films in Tamil, and his last release was Thotta that had Jeevan and Priyamani in the lead.

M Bhaskar’s work as the Tamilnadu Film Producer’s Council’s secretary is well appreciated in the industry. He was instrumental in making the council cash positive, and he also worked as CBFC Chairman in Chennai. He passed away in 2013, and he had a movie with newcomers in production titled Oodhari.

Breakout Movie: Theerpugal Thiruthapadalam

M Bhaskar is known for his moral dilemma thrillers and drama. But it started with Theerpugal Thiruthapadalam. The movie is about Radha (played by Ambika) is a hysterical possessive woman who loves her husband Rajesh (played by Sivakumar) and daughter (played by Meena). One day, when Rajesh returns home after work, he finds Radha sleeping in a dilapidated state and a dead body in their study room. He discards the corpse, but Radha doesn’t have any inkling of what happened. The rest of the story is about how Rajesh finds the truth about his wife and the dead body.

When you watch the movie, you will be surprised at the way M Bhaskar jumps into the conflict and sucks you into the narrative. The movie analyses the moral dilemma of the characters and interestingly doesn’t shy away from discussing infidelity (in fact, the 80s movies were more open about these issues). Although the film meanders into unwanted comedy sequences and has a usual twist (wouldn’t have been a typical twist in that era), the movie is definitely worth a watch.

The movie was a big hit for M Bhaskar, and he started making similar films like Thandikapadatha Nyayangal (dealt with infidelity) and Oru Sumangaliyoda Katha (Malayalam). He moved on to courtroom dramas like Pournami Alaigal, Sattathin Thirappuvizha etc.,

Managing Your Technical Debt
By: Jessica Torres
Tags: Concept, Software Development, Programming Tips, Technical Debt, Computer Science

WHAT IS TECHNICAL DEBT?

If you’ve ever worked on a professional project or even just an assignment, writing code, you’ve almost definitely heard an adage similar to “Get it working”. As programmers we are encouraged, more often than not, to worry about the passing tests or the basic functionality first, and the optimization of our code second. One of the major problems with this is that the projects and the assignments never stop coming and it very swiftly becomes impossible to actually circle back. You wind up leaving this trail of technical I.O.U.s behind you, promises of cleaner and more efficient code, edge cases you made note of but also made the decision to take care of later on, changes that you may have every intention of making in the near future but most likely never will. This leaves a mess for one of two people, future you or future “other guy” programmer (neither of whom will appreciate the added workload).

These consequences of “limited solutions”, the implied costs of any and all additional reworking that has to be completed, they are what we refer to as Technical Debt. To be clear, technical debt is not always a result of a decision made in the moment by a programmer, and we will see more on the other situations that result in debt later on in this post. But in truth, a lot of the time you’ll spend as a developer will just be spent taking care of some form of these technical debts, and as such, it is in everyone’s best interest to try to minimize these debts early on.
She of Might, She of Light
By: Nicholas Aw
Tags: Sunset, Creative Writing, Prose, Dusk, Sun

You climb to get closer, and in like manner so she sinks. She descends gradually, lowers her fiery eyes into a gentle gaze, and eventually, at the convergence of the ethereal, you no longer look up towards her — she of might, she of light. You realise that at that point, you and her are level, and at that point, you are the closest you will ever get to her in 24 hours. She realises this too, and seems to linger.

Now this is what the day has been for. This coming together. If you had a good day, you tell her. If you had a bad day, you tell her. She does not praise, she does not rebuke.

But while she of might and light appears to be tame and lame, she is no less cunning, no less proud. She demands your attention, for if you are not careful and look away, she takes it to heart. Now your hurried little mind catches itself, and urges your eyes back to her. But lo, she has gone! And now you both grow apart, and you sigh, the ensuing breath the first since she approached.

These are how evenings should be spent — by attempting to shorten the distance between yourself and the sun.
ICO Review — 5 reasons why NaviAddress should be the future of addressing system
Tags: Cryptocurrency, Ico Review, Addressing System, Blockchain, Naviaddress

1. The problem of current addressing system

Addresses, whether with the longitude-latitude system or the postal addressing system, are essential elements of our current society. They mainly allow to “represent” a place, be it a building in a city or a place of commercial activity. Let’s start with a bit of history!

The longitude-latitude coordinate system, invented by the famous Greek astronomer Ptolemy, was the first location system to be used on a large scale. Isaac Newton formalized the principle into a system that described each place on Earth with a set of numbers, letters, or symbols. Currently, it remains one of the most used systems, but it is far from ideal and it presents a lot of defects: a complicated format to understand for the uninitiated cartographic systems, a complexity in the conversion to a Real “location” and especially a non-user-friendly system that does not allow to use it daily.

From the 18th century, postal addresses made their appearance at the time when cities developed; the good memory of local factors had become insufficient to allow the parcels to be delivered to thousands of people every day. But it was in the 1930s that this system became global. Although this is the system we currently use, it also has many flaws:

Almost one in two people (about 4 billion) do not have an address. And without address, impossible to make orders online for example. This is create a large social disparity that no government is addressing at the moment.

And without address, impossible to make orders online for example. This is create a large social disparity that no government is addressing at the moment. Delivery addresses are not verified upon first use which results in delivery errors and causes significant losses.

which results in delivery errors and causes significant losses. Coffee shops, hotels, restaurants, retail outlets, … All these institutions are poorly identified for international tourists and expatriates making them, in a large majority, inaccessible and therefore generates potential sales losses.

With these defects of the current systems and if we projects ourselve in today’s increasingly connected and globalized world, the need for a complete, functional and universal addressing system becomes even more pressing. Many attempts have been made throughout history to set up such a system, but so far none has succeeded.

Naviaddress seeks to change this by creating a decentralized solution for universal digital address.
Robots: Menace or Pathos?

Welcome to the first weekend writing prompt of 2019. Before I set you on your imaginative writing adventures, let me talk a little more about why these are weekend prompts and not just prompts, sprints, exercises, etc.

Writing prompts are designed to stretch your thinking, to make you write around certain roadblocks by providing arbitrary restrictions you would not otherwise put on your own writing. But prompts are often also short, designed to be temporary challenges like doing a crossword. After you’ve managed to find your way around the restriction of the prompt you get to pat yourself on the back and consider that prompt completed, that challenge met and overcome. When writing prompts take only a few hours or even less time, it’s easy to walk away from them and forget all about the lesson you learned form the exercise. It means nothing to have strong muscles if you never do any heavy lifting.

A writing prompt ought to be revisited more than once if you want the lesson to stick. So this weekend, read the prompt and try your hand at it. Then again tomorrow and again the next day. Have the prompt on your mind all weekend so you can either really polish the piece or, and in my opinion even more beneficial, you can have a few different versions, multiple ways of completing and satisfying the prompt. That way anything you’ve learned will be remembered and more likely to resonate in your other writing.
100 design lessons for 2021
By: Ux Collective Editors
Tags: UI, User Experience, UX, Resources, Product Design

Things are not ok. We are in the middle of a global pandemic that has taken the lives of more than a million people. Those of us who have been able to keep our jobs in the economic crisis have been working remotely, leaving us feeling isolated and struggling to remain productive while the world burns outside.

As if that wasn’t enough, state violence against marginalized populations has escalated, while the gap between the rich and the poor has widened. Across the world, we are seeing the rise of authoritarian regimes fueled by the manipulation of truth and the dissemination of alternative facts on social media.

Things are not ok.

As the year ends, we can’t help but ask ourselves: what’s next for Design? What should designers expect for the year to come?

In the next coming weeks you are probably going to start seeing a lot of articles shared online about “The Coolest Design Trends for 2021”, or “New Technologies Every Designer Should Know in 2021”. In the six years we have been publishing our end-of-year State of UX report, we have always challenged ourselves to discuss our industry beyond tactical visual trends or insular new technologies.

In this edition, we decided to expand even further.

The King’s Folly
By: Mark Starlin
Tags: Marvel, Compassion, Fiction, Fantasy, Counseling

In a time long forgotten, there lived a King. He wasn’t the wisest King, but he cared for the people he ruled and was rarely cruel.

The King surrounded himself with wise counsel. Although he did not always heed their advice. One example was the stained glass tower.

On a day like many other days, when nothing of great importance was happening, the King decided to go for a ride. The King enjoyed riding in a field that spread out treeless as far as the eye could see. After riding for a while, the King stopped and dismounted. He looked around. In a fit of whimsy, the King decided to build a tower made entirely out of stained glass. It would stand in the exact location he stood and would be a marvel.

Upon returning to the castle, the King called his advisors into the great hall to seek their counsel. After telling them of his plan, the King waited on their response.

The counselors looked at each other in disbelief. The elder counselor then spoke.

“Your Majesty. The idea of a stained glass tower is quite imaginative. But I fear it would be far too fragile to withstand intense weather.”

The King nodded, but did not speak.

Another counselor spoke out.

“Your Highness. What would be the purpose of this tower? Surely it has no defensive or practical use. And it would be painstaking to construct.”

Again, the King nodded, but did not speak.

A third counselor spoke his mind.

“My King. Stained glass is difficult and expensive to make. The cost of such a tower would be high. And the result would be a tower easily destroyed by enemies or nature.”

Once more, the King nodded without speaking.

Despite the counsel of his counselors, the King would not be deterred. So artisans and builders across the land were called into service to construct the tower.

The project required extreme care and took considerable time to complete. But when it was finished, it was a wonder indeed. Sunlight passing through the tower washed the surrounding fields with every imaginable color. People came from far off to see the marvelous sight.

Soon, though, people began calling the tower The King’s Folly, for it was surely a waste of time, money, and stained glass. Locals began wagering on when it would fall.
The #TechHearings Thoughts from my time in Product Safety at Twitter
Tags: Security, Russia, Tech, Social Media

I created the Product Safety and Security Team at Twitter. At different points in time I was responsible for the engineering of tools to mitigate Abuse, Compromised Accounts and the Login Infrastructure up to and including 2 Factor Authentication and Password Reset. I saw first hand the beginnings of the types of actions that are now being discussed in the US Senate at the #TechHearings.

The tepid response by senior management to the millions of accounts created by bad actors and how they were using the platform discovered in our research, is one of the reasons these hearings are happening today. It was the growth at all cost mentality that blinded many at Twitter to how the platform was being weaponized by the alt-right and as we are finding out, by Russia as well. This growth at all cost was a source of frustration for many of us working in Product Safety

The social media platforms we use everyday have now become the propaganda battlegrounds of the 21st century. The trust we have put in what our ‘friends’ post on facebook, Instagram, and Twitter is influencing our political views, our social views, our views on race and gender, and our views on right and wrong. And this influence has been manipulated with devastating effect, not just by the platforms for profit, but by those that would divide us and pit us against each other.

It is a fact that foreign governments used social media to influence the moods, emotions and decision making of millions of Americans. It is also a fact that the growth and profit at all cost mentality that was driving Twitter in 2015 and Facebook in 2013 left the door open for this manipulation. A door they refused to acknowledge much less close.

Tech companies have been hiding behind the saying “we are just a platform” to brush off any responsibility. And yet many of those same people will decry how Fox News is nothing but propaganda. The fact is, Twitter and Facebook reach more people on a daily basis than Fox News, CNN, MSNBC and the NYT combined. Yet they have shirked this responsibility and in effect have been the most effective way to disseminate propaganda in the 21st century.

Billions of dollars of wealth have been created because of these platforms. And our democracy may have been irreparably damaged in large part by these very same platforms. I don’t have a list of solutions to this. However I do know that if facebook/Twitter put the same emphasis on tackling this as they have on optimizing their ad serving platforms, we would have seen more progress.

I tweeted recently:

It should bother all of us that platforms with this much influence have, up to this point, taken almost no effective steps to mitigate this type influence. And while I am not pushing for government intervention, I do ask our representatives to push for concrete metrics to track the progress all the tech companies are promising to make. Metrics that are regularly published and peer reviewed. Metrics that are defined and mutually agreed upon. With civil and financial penalties for non-compliance. This would be a good start.

How sweet you are when I am on the brain.

How stellar I think you are everyday.

We love, we live, but never seem to gain

unless it comes to when and how we lay.

We tend to reach for one another’s care

while by ourselves we grow recluse and cold.

We complement, though compliments are rare

and never do we let our hearts unfold.

Our heads don’t understand the growing strain.

The universe doth watch and let us be.

In time, these times will prove themselves a drain.

The day we find ourselves we set us free.

I say all this to make this one point clear:

I need to cross you out or keep you near.

‘Set us free’ was originally published as ‘Sonnet’ in ’25 Sense: the poetic works of Tyree C. Worthy’ in 2016.
Liquidity Provider — Altonomy
Tags: Cryptocurrency, Announcements, Bitcoin, Fintech, Partnerships

We recently revealed the Pluton Liquidity Injection Programme which involves five exchange partners that will help increase accessibility of PLU and usage of the Pluton (PLU) token.

Summary

We hosted a successful micro-sale on our own internal platform, the PlutusDEX.

We have revealed two of our five exchange partnerships — this includes a listing of PLU with the current highest volumes on BitMax.

Our Tier 1 listing has moved forward in the queue — this is up next and will be revealed on 17 Nov 2020.

Our Liquidity Provider — Altonomy

To accommodate any potential volume increases, we have partnered with Altonomy to ensure PLU is liquid across our exchange partners. The liquidity provider has supported Top 10 coins such as Tether. You can find out more about Altonomy here.

Note: Pluton was designed to be an in-app utility token and is not here to be speculated upon. The partnership aims to increase accessibility of PLU to be used in-app.

What will this Achieve?

The partnership will help improve accessibility of PLU by ensuring swaps between the token and various other currencies are actioned.

“Altonomy has worked with industry-leaders which makes it a suitable fit for Plutus. This collaboration, coupled with our top tier partnerships, will help increase accessibility of PLU.” — Danial Daychopan

More to Come…

There are several more announcements emerging this year. The next exchange reveal is of our Tier 1 partner on 17 Nov 2020. The sale of which will take place on 26 Nov 2020.

Follow our Medium blog where we will cover all news announcements in the most detail, or our Twitter for highlights.

If you have any questions and want to speak directly with a team member, or members of the community, join us on Discord or Telegram.

If you reside in our supported countries and you are yet to try the Plutus app and card, then we recommend you sign up here and give it a go.
Use your phone ( Android, iOS, Windows) as a webcam for PC, Mac, or Linux
By: Miroslav Maksimovic
Tags: Mac, Windows, Phone, Linux, Webcam

Have you ever been in a situation that you have a meeting online and your webcam has a bad resolution?

If so, you probably have been considering options like connecting your phone as a webcam.

Personally I use Linux and there is no such a client like EpocCam, or iVCam (only PC, Mac), which can be pretty annoying.

So I’ve figured out a simple solution to my problem which applies to all devices.

Steps:

1. Download client app such as Zoom on desktop, notebook, mobile, 2. Launch a meeting, and connect with all devices you want. 3. On mobile enable camera and mic. 4. On desktop, notebook disable camera, mic and sound.

So these steps apply to case where you want to have high res picture but also able to be on your notebook in case you want to share screen etc…

You can customize these steps in any way to get what you want.
Create Heatmap in R Using ggplot2

Create Heatmap in R Using ggplot2

A Step by Step Tutorial

A heatmap is a graphical method of representing numerical data originally contained in a matrix format. Rather than using numbers — something we observe in a matrix — a heatmap depicts the value of an observation (cell in a matrix) using different colors.

In this article, we will learn how to create a heatmap in R using the ggplot2 package.

Dataset and Data Visualization Plan

We will use a subset of a dataset (from gapminder) which has data on the per capita CO2 emissions in 192 countries over the period of 1800–2010 (with many empty cells though).

For simplicity, we are interested in visualizing the changes in per capita CO2 emissions in the twenty five most populous countries over the period of 1950–2010. Also, rather than looking at every single year, we will consider per capita CO2 emissions in each of these countries during specific years (1950, 1955, 1960,……, 2010).

Let’s start coding! :)

Step 1: Load the packages and the dataset in RStudio

library(dplyr)

library(ggplot2)

library(reshape) #the dataset (.csv file) should be located in the same folder where your R code (.R file) is located. Also at the beginning, click: Session -> Set Working Directory -> To Source File Location g<-read.csv(“heatmap_co2.csv”)

Step 2: Select rows and columns using select and filter functions from the dplyr pakage

#Select certain columns (specific years)

g1<- g%>%select(country,X1950,X1955,X1960,X1965,X1970,X1975,X1980, X1985, X1990,X1995,X2000,X2005,X2010) #Select certain rows (specific countries)

g2<- g1%>%filter(country==”China”|country==”India”|country==”United States”|country==”Indonesia”|country==”Pakistan”|country==”Brazil”|

country==”Nigeria”|country==”Bangladesh”|country==”Russia”|country==”Mexico”|country==”Japan”|country==”Ethiopia”|country==”Philippines”|country==”Egypt”|country==”Vietnam”|country==”Congo, Dem. Rep.”| country==”Turkey”|country==”Iran”|country==”Germany”|country==”Thailand”|country==”United Kingdom”|country==”France”|country==”Italy”| country==”Tanzania”| country==”South Africa”)

Let’s have a quick look at the g2 dataframe.

We want to remove the Xs from the beginning of the column names.

Step 3: Remove Xs from the column names (X1950, X1955,…..,X2010)

#Remove “X” from the beginning of column names

for ( col in 1:ncol(g2)){

colnames(g2)[col] <- sub(“X”, “”, colnames(g2)[col])

}

Okay, now g2 becomes this:

Cool! :D

Although the data presented above in the matrix format is useful, it is difficult to keep track of all the numbers and to identify patterns just by looking at it.

This is where a heatmap comes into play and makes the visualization lot easier!

Step 4: Change the format of the dataframe using melt function from the reshape package. This step is crucial!

Previdya: Wisdoms of Rapture

Aphorisms from The Chambers of Rapture

Photo by Ahmad Odeh on Unsplash

When The Chamber of Rapture’s three chief deities spoke,

the people of Ryn were wise enough to listen.

When the gods stepped away, the pen kept their words alive.

Goddess Melodra, the divine child, shows us the simple wonders of life.

Remember, Spring comes each and every year.

Life gives and takes at once.

Toil and tribute, hand in hand,

Savor the feast, dance to the band!

Where you live, there’s hope.

God Lor’s passion burns hot.

Passion is a fire,

Warm, quick, and hungry.

A joyous fire can still burn.

Give me infatuation,

but love takes time.

A moment of fear is a moment lost.

God Geredin’s good days bloom eternal.

Passion, well pruned, will last a lifetime.

Every harvest must be sown.

Where weakness festers, might can grow.

A mind possessed is a terrible thing,

addiction’s the thief of joy.
Holes— a Free Verse Poem Response
By: Christina M. Ward
Tags: Poetry, This Happened To Me, Family, Short Story, Writing Prompts

Child-sized hole in my living room wall.

The intrusion of truth, packed in with syrupy lies.

Hole in my bedroom wall, this one I saw him do.

He could not explain that one away.

Holes in my life, shattered like drywall

in the midst of his anger.

Holes can be repaired — but not before lies

must cover them, with excuses, with stories;

spackling with shame is a terrible way to repair.

I covered up holes. In the wall. The ones on my face,

my eyes, my ears, my mouth (that one must stay shut, right?)

I painted them over in carefully selected shades

of buttery-white, eggshell finish, easy to clean.

Holes. You can fall through holes if you aren’t careful.

Legs, arms, heart — right through holes in the wall

into spaces of black that do not see the light.

Lies are best kept in the darkness anyway.

Falling in is convenient. It spares us the explanation.

If I could go back, for only a moment,

I’d leave those holes, take you both by your little hands,

put you in a Red Ryder wagon and walk down the street.

I’d make sure you had on your jackets and toboggans

and had a toy in each hand. We’d walk and point out

the birds in the trees, the clouds drifting by.

We’d walk to safety, together, in a place with no holes,

only windows to the outside, where dreams are free

to float like air-born seeds on the wind.

I would tell you everything is going to be ok,

if only there was a hole through which I could climb

to take me back to those days.

Summary: Female Investor Interest In Cryptocurrency Doubled In Six Months; Lithuana Announces Comprehensive Cryptocurrency and ICO Guidelines; Ethereum Co-Founder Joseph Lubin Says Blockchain Will Be “Orders Of Magnitude More Disruptive” Than The Dotcom Bubble

Female Investor Interest In Cryptocurrency Doubled In Six Months

According to CCN, a report from a UK exchange found that one in eight women would consider investing in a cryptocurrency. The 13% figure is almost double from 6% last year who said they would consider investing.

As one might expect, these numbers only rose when looking at responses from millennials. With millenials, one in five are “likely to invest in a digital currency”.

Another report showed that women are less likely to experience what’s commonly referred to as Fear Of Missing Out (FOMO), and often consult friends and family before making final investing decisions. On the other hand, men are more likely to act like “lone wolves” and make investing decisions on their own.

Lithuana Announces Comprehensive Cryptocurrency and ICO Guidelines

According to Bitcoin.com, Lithuania’s Ministry of Finance has published comprehensive guidelines for cryptocurrency and initial coin offerings (ICOs). The guidelines cover aspects of regulations, accounting, taxation, and Anti-Money Laundering (AML) for the industry.

The Lithuanian Minister of Finance Villus Šapoka said:

“We acknowledge that the brave new crypto economy world is here to stay, this is why we encourage and invite its participants to innovate and create in Lithuania…We are one of the first ones in Europe who prepared comprehensive guidelines on the legal framework for ICO projects covering regulatory as well as taxation and accounting.

These regulations should provide some more reassurance to investors and miners in the cryptocurrency space that the space will be properly regulated.

Ethereum Co-Founder Joseph Lubin Says Blockchain Will Be “Orders Of Magnitude More Disruptive” Than The Dotcom Bubble

According to Cryptoglobe, the co-founder of Ethereum Joseph Lubin lauded the enormous potential of blockchain technology describing it as “orders of magnitude more disruptive” than the dotcom bubble.

Lubin was very positive about the state of the blockchain industry, stating that:

“We can see sectors, industries, supply chains, any sort of value chain starting to build these collaborative systems…There was a tremendous amount of creative destruction in the dotcom era that laid the foundation and taught all of us how to build an effective internet, an effective world wide web, and really transform society. I think that we will see dynamics like that in place in the blockchain space.”

In a similar comment, professor Niall Ferguson compared the blockchain industry to the 18th century equities market where people could trade equities in corporations for the first time:

A Sonnet For The Frustrated Romantic

(Read this before being the honored lunch guest)

I told myself I’d write myself a sonnet

that would wow all the ladies

but I ain’t picked up my pen, so better get on it

to find a romantic theme — perhaps Hades —

’cause I get no ideas peering at the night all starry

nor seeing the sliver of moon shining on your eyes

so I’m cramming my head to avoid writing malarkey

but all that comes to mind is a swarm of dirty flies

feasting on soured milk and block of moldy gouda

joined by a grotesque beady-eye hyena

licking the remnants of its last meal of a barracuda

it absconded with while traveling in Argentina

but I realized that the flies and hyena were still hungry

so instead of eating spoiled food they feasted on me.

As the Junior Economic Club of Toronto faces the unprecedented circumstances of our world today, we must remain confident in our ability to capitalize on the new possibilities presented by a virtual year.

First, allow me to express my gratitude to you.

To each and every person who has attended a JEC event in the past, to each and every person who will attend a JEC event in the future.

To those who have joined us in our undertaking of new initiatives, looking towards a world where your social and economic circumstances do not hinder your pursuits.

To those who have supported us by sharing their experiences, time, resources, and space.

To all the youth in the GTA who have allowed the organization to prosper in the five years since inception.

Second, allow me to promise you our commitment to the community.

We have already hosted our inaugural International Fall Forum, bringing together over 200 students from across the world.

Later on in the year, we look forward to providing students with the chance to engage in an artificial intelligence program and compete in a business case challenge, similar to the one that had been planned previously.

Third, allow me to ask for your support in the coming nine months.

The basis of the Junior Economic Club of Toronto rests in our mission: to provide equal opportunity through financial literacy.

With the changing times and necessity of adaptation, we have expanded to the broader field of business management as a whole, as well as the intersection of technology with the two.

We hope that you will consider taking part in and benefiting from the initiatives that the JEC is working hard to provide you with, as the fundamental purpose of this organization lies in the enrichment of its audience.

All the best,

Stephanie Xiang

How to Determine If NoSQL Is Right for You
By: William D'Souza

Do You Need a NoSQL Architecture?

If you find yourself starting a new application or have encountered issues with running your system off of a relational framework, it’s worth exploring the world of NoSQL and finding a tool that will fit your needs. Here are a few questions that can help you make the choice.

Do I need the ability to handle big data with speed?

Relational databases generally don’t handle big data as well as NoSQL databases. Relational systems are powerful in terms of consistency and availability. If the system you are designing is going to be on a small scale and it doesn’t have the potential to be hitting deep waters, then it can work for you! However, if the application is already experiencing problems that come with harvesting large amounts of varying data, a NoSQL solution will help. They are a handful of tools that can be chosen that will sacrifice either consistency or availability for the ability to scale.

Are you storing structured, semi-structured and unstructured data?

Does your application involve storing a variety of data types? Will there be a need to store audio/video, transcripts, webpages? Is there the possibility that you could be mixing up structured and unstructured data? If you answered yes to any of these questions, then there’s a good chance that the NoSQL architecture is a good choice. Creating wide tables to store your data is not the best solution, and creating a table for every subdomain isn’t either. Although these could potentially work, a schema-less architecture is better suited for this as every entry can have its own set of attributes which can take on its values.

Is scalability important to you?

If money is not an issue and you can afford to burn it, then scaling vertically with a relational database will work fine. Buying more hardware (in-house or cloud) will be expensive when you need more performance because of storage requirements. If you find yourself being restrained by a budget constantly or just want to be economical, then the ability to scale horizontally with a NoSQL model will work amazingly! If your data storage requirements grow too much, you can add inexpensive servers and connect them to your cluster, working as a single service. This is one of it’s biggest strengths.

Are you shipping lots of data around a network?

Processing jobs and queries pass through several servers, providing very high levels of parallelization for ingestion and workloads. Being able to calculate aggregations right beside the data is essential and there isn’t much of a need for a warehouse system that updates itself every night. Data does not need to be passed around a larger network to achieve analysis, as its ability to aggregate and efficient query handling quickly paves the way for a well performing system. If there isn’t a lot of data being moved around, then a relational model will work just fine.

The Revolution At Home

A war that tore families apart

Courtesy of Pixaby by JamesDeMers

The battle tonight could decide everything, father. You know what Jefferson says: ‘a nation is great only when it is free’.”

“You’re being idealistic, my boy. These leaders you believe in will tax us and steal our freedoms, just like the Brits.”

“We must fight for our independence, father!”

“King George is a good man; my business depends on the British. You’d do well to remember that. This Republic you dream of will crumble, they all do.”

As he spoke a fist thundered on the door.

“What’s going on?”

“That will be the minutemen, father. I have signed us up!”

The Echo and the Reflection

The smallest stream is destined to come

Back into the endless ocean

of Consciousness — beginning with no end.

The echo is returned

to you

You are the self, and

The non-self

The caller, and

The receiver

The quest, the question burning at your lips,

And

The answer, buried in your own heart!

The thirst is quenched

The hunger, tamed

The ego, conquered

The reflection of your own

Essence:

Mirror of Life,

Mirror of

The Soul.

The pieces of broken glass,

Sharp edges twinkling in the cosmic eye

Are reunited,

One.
