How to leverage Data Science and Optimization for Economical Supply Chain Network Design?
By: Vikas Garg
Tags: Operations Research, Supply Chain, Optimization, Data Science, Decision Making

Problem Statement & Objective

In my example, I have a finished good (FG) which is made of Part-1 and Part-2. Part-1 is manufactured at location 𝕃. The 𝕃 ships Part-1 to the distribution center (DC). The DC holds the Part-1 in inventory and follows the ‘make-to-order’ strategy i.e. as the order is received, DC outsource the Part-2 from a local supplier and assembles the FG. Then FG is shipped to customers using parcel delivery. I have been given a set (ℕ) of locations where DC can be opened. Out of ℕ, we have further given 𝕁 ⊂ ℕ as the preferred location. My aim is to identify the locations for DC so that the total operating cost of those DCs, shipping costs, and the assembly costs are minimized given the demand of each customer is satisfied.

Further, if we decided to ship the products from 𝕃 to customers, then the total cost is estimated to be more than $27 million, shipping cost accounts for 60% of the total.

To optimize the SCND cost, I am proposing a Mixed Integer Programming (MIP) model [To learn more about MIP and optimization, please check mipmaster.org blog]. The detailed mathematical model formulation and the problem description is available at github. Next, I describe how the OR and ML help in lowering the anticipated cost of $27 million.

am I different from you? from me?

Seattle Alley, photo by debora Ewing

this cold puts pressure on my cracks

I pull frigid hands up into my sweater

but the ears, they’re on their own

fractured conchoidally

cold words rattle down the canal

maybe slip through the fissures

another me would panic

try frantically to plug up holes

stop meaning from escape

but I apprehend that one; we

have to work as a team now, I say

my permutations queue

we’re a soup line these days

phrases like old coins pocket-slip

between ladle and line

on the bare hard sidewalk

one of me smiles in passing

one of you looks askance

Tectonic

The Earth is a fragile planet

Photo by Louis Maniquet on Unsplash

The Earth is a fragile planet

we teeter near the edge

it’s no climactic artifice

that’s driving in the wedge.

The trembling winds of change

causes each piece to move

the purple distant range

hide secrets in reprove.

Dark rumbles of thunder

droplets of silver rain

movement from down under

floodwaters on the plain.

Tall tectonic edifices

crafted by raw elements

mountains with rock faces

made in tectonic moments.

Building new tomorrows

hope love and charity

melting bygone sorrows

accepting overt verity.

Opening locked doors

releasing desperate demons

movement from deep cores

liberates with new meanings.

Deep tectonic plates

rub rise and then erupt

accompanied by the fates

there ready to corrupt.

Sending swift tsunami waves

to obliterate the shore

feckless to their early graves

life swallowed by the maw.

Tectonic windows

opened by erosion

sighing last throes

then a volcanic explosion.

Climate change creeps

whistling in a seashell

the rising seascape sweeps

towards earth death knell.

Comets in the heavens

stars streaming from above

raining night-time sessions

then there’s the push and shove.

On one side the deniers

the truth’s so clear to see

caring for our planet

is up to you and me.

Aware of the whole gamut

joined by a fragile suture

the wallpaper of our minds

obscuring the cure.

Closing up the blinds

or hiding in the booth

strategic dour denials

only hides the truth.

The known mistrials

and shifting of the blame

one voice and single action

is an appropriate refrain.

Why Is Ruth Ginsburg’s Death So Important?
By: Tree Langdon
Tags: Law, Politics, History, Self Improvement, Justice

The Supreme Court of the United States

This court is the highest in the land and will hear appeals to lower court decisions if four of the supreme court justices agree the case has merit. The concept of this court was established by the Constitution and created by the Judiciary Act of 1789.

The court’s goal is to ensure Equal Justice For All Americans under the law.

Currently, the court is made up of the Chief Justice and eight Associate Justices. The president is responsible to nominate any new Associate Justices. The positions are lifetime appointments.

How is the voting split now?

There are nine positions on the Supreme Court, with a firm split of five conservatives and four liberals. Justice Ginsberg held a liberal seat. One of the conservative justices, Chief Justice Roberts, has sometimes split from the other conservatives and cast his vote with the liberals.

If Justice Ginsburg is replaced by a conservative justice, it will require two conservative justices to shift their vote to the liberals in order to prevent major precedent-setting decisions such as overturning Roe vs Wade, a long-standing abortion rights decision.

Women’s rights have been teetering on the edge for years.

As an Associate Justice of the Supreme Court of the United States, Ruth was appointed to the supreme court in 1993. She was the only woman on the court for more than ten years.

A character and an icon, she died on September 18, 2020, after a long fight with pancreatic cancer.

Her last stated wish was that her replacement is to be made by the new President, after the election.

”Justice Ginsburg paved the way for so many women, including me. There will never be another like her. “Thank you RBG. — Hillary Clinton (@HillaryClinton) September 19, 2020

8 reasons why her death is significant at this moment in history.
Big Data Sets Queriying and Analisys
By: Iván De Prado
Tags: Computers, Distributed Systems, Hadoop, Jaql, Scalability

The use of SQL and databases to analyze and extract data from datasets is a common practice. Functions like GROUP BY, ORDER BY and aggregation functions like COUNT, AVG, etc are useful and flexible enough. Tasks as generating statistics from log files or extract information from a dataset are easy with SQL.

But the problem comes when you have a very big dataset (GB or TB of data). In those cases, the databases simply do not work. It is needed to distribute the computation. There are two projects that can help.

Pig is a project built on top of Hadoop. As they say:

The highest abstraction layer in Pig is a query language interface, whereby users express data analysis tasks as queries, in the style of SQL or Relational Algebra.

The computations in Pig are expressed in a language named PigLatin that provides similar pieces than SQL but more powerful. The data are stored in the Hadoop Distributed File System (HDFS), and the computations are distributed along your Hadoop cluster. That means that you can query through terabytes of data. Currently, Pig is working and they are planning to release a new version with a lot of improvements in the next months.

Jaql is another project, younger than Pig. Jaql is a query language for JSON inspired in SQL, xQuery and PigLatin. But they are planning to make it distributed using Hadoop. Files can be read from HDFS or HBase.

In conclusion, these two projects can help a lot when extracting information from big datasets.

Three Celestial Messages from the Great Conjunction of Saturn and Jupiter

The upcoming planetary alignment might impact your love, spirit, career, life and more

Art from Getty images/ Allure: Clara Hendler

The biggest astrological event of out lifetimes arrives on December 21. Jupiter and Saturn will appear the closest they have been since 1623.

The vibrations of the two planets will blend and work together effortlessly.

Henry Throop, an astronomer in the planetary division at NASA perfectly explains why this phenomenon is extraordinary.

“You can imagine the solar system to be a racetrack, with each of the planets as a runner in their own lane… From our vantage point, we’ll be able to see Jupiter on the inside lane, approaching Saturn all month and finally overtaking it on December 21.”

We are lucky to be able to witness the birth of a new consciousness as the energy created by the Great Conjunction will change the way we think and live.

The alignment will be special because it’ll occur in the sign of Aquarius, and the planets will only be 0.1 degrees apart.

Aquarius is the most humanitarian sign and symbolises harmony. It encourages us to nurture our unique qualities and let our hearts guide us from a foundation of love.

The air energy of Aquarius is about high-tech and creating things that work through light waves.

The association of wise Aquarius, boundary-setting Saturn and passionate Jupiter announces a new age of enlightenment.

I believe there are three fascinating messages from the Great Conjunction.
Uber being Uberized

Multi-Sided Platforms (MSP)

This concept can be shortly summarised as the ability of connecting two or more participant groups. This was made possible as internet has massively reduced search costs and the smartphone enabled this unlimited access on the go.

Today when you have a heated argument with your friends around one topic, you can quickly validate the answers in your phone and move on.

The following image clearly captures the business changes that are happening:

Change on business connections

However, there are some caveats to all this innovation. Topics such as the number of the sides present on the platform, how to price the products/services and how governance is applied will massively affect the resulting service.

Uber is a flagship reference on this domain and gave rise to a new way to approach mobility. In the absence of big entry barriers, if Uber wants to survive they need to look at the problem from another perspective.

Entry-deterring strategies

There are three commonly discussed entry-deterring strategies:

Limit pricing – low price before entry

Predatory pricing – low price to force exit

Strategic bundling – combine services at a lower cost that the joint purchase

Uber usually introduces low prices when they enter. They have positioned themselves in multiple categories (e.g. UberX, UberBlack) to accommodate multiple price segments. However, recent market entries show that when we look at traditional companies/taxis, Uber is not the cheapest.

So, Uber is now trying to push up the costs to compete in this industry by strategically bundling more services in the ecossystem.

If the first step was trying to disrupt themselves on a segment (self-driving cars), now the focus is on delivering the ultimate app for mobility services (exemplified by the acquisition of Jump Bikes).

Their strategy appears to be now to integrate every kind of transportation instead of just focusing on the cars/motorcycle segment and diversifying on the goods transported (e.g UberEats for food)

I will take the risk and say that we will probably witness the creation of a Uber membership monthly fee with access to cars, bikes, custom route buses…

Examples of already deployed services, some competitor examples and possible white spaces

Another way of delaying entry is to “informally” agree with regulation. I say informally because they cannot publicly agree as it will affect their cost structure. But as regulation is proven to defend the incumbents it is clear what will be the path.

Meanwhile, a Uber cost structure disruptor is being created…
Rape Culture Is Real No Matter What You Tweet
By: Lena Melillo
Tags: Rape Culture, Free Speech, Sexual Assault

Trigger Warning: Rape

On June 16th, Milo Yiannopolous tweeted, “If you’ve heard about a rape, it’s fake.”

@nero/Twitter

This week, just a few months after composing this tweet, Milo Yiannopolous is slated to speak on campus at an event hosted by USC College Republicans.

On a campus where 30% of women and 7% of men have experienced non-consensual sexual contact*, it is imperative that we recognize and validate these experiences. Inviting someone to campus who says rape reports are false does the opposite. On a campus where at least 80% of survivors do not report non-consensual sexual conduct, “if you’ve heard about a rape, it’s fake” is not merely an offensive tweet — it is the very language that makes our campus unsafe. It is a call to doubt survivors. It is a refusal to hold offenders accountable. It is a reminder to survivors that they should be too scared or too ashamed to report their rapists. An endorsement of this rhetoric is simply unacceptable.

Now, USC College Republicans is allowed to invite any guest they find relevant to their community and to their mission. However, every student, regardless of ideology or political party, also has a duty to foster a safe and inclusive culture on campus.

As a feminist and self-proclaimed leftist, I know the College Republicans and we don’t agree on everything. We may not even agree on most things. But this is not about partisan politics. Providing resources for sexual assault survivors is not a liberal agenda and rape prevention shouldn’t be a single party issue.

I am not asking anyone to agree with my personal political views. What I am asking is that every student leader, no matter what organization they represent, carefully consider and recognize the impact of the people they invite to speak. I am asking that every student recognize that words matter — that endorsing Milo Yiannopolous’s words makes our campus less safe.

I sincerely hope that USC College Republicans continues to facilitate important conversations on this campus. After all, a vibrant and thriving democracy depends on conflicting opinions and diverse, intellectual discourse. But I refuse to welcome a person onto this campus who demeans and degrades survivors of sexual assault. I will not stand by silently as my peers’ safety and well-being is put at risk by violent and misogynistic rhetoric.

Rag And Bone

Tags: Short Story, Fiction, Creative Process, Prose Poem, Poetry

The old man stands silent before the canvas, staring down the void. Every day, for seventy years — at least those he remembers, and he swears he remembers sitting on the floor as a three year old, paints and crayons scattered around, intent on bringing forth the colours he saw in his head — every day he created anew, and yet — and yet. Was it really all over? He thought he would die, hands stained in oils and turpentine blasting his lungs — but here he is, a blank; worse than failure.

He looks to his old companion — the collected Yeats, spine split open on “The Circus Animals’ Desertion”. Maybe it happened to others — but he’d once seen himself as a god, as Vulcan — molten, virile, endlessly generative. William B made it to seventy-three, his words pushed through with urgency, recreating the language of his youth into A Vision of age and ill-health defeated. And the painters he adored continued on — Picasso poured pure instinct, expressive to the end — lust reborn in ancient forms, consuming life in death.

But here, bordered by the remnants of his life’s work, he is alone. Windows that once poured light, now dulled with grime and nicotine tar. In the corner, the old grey tabby yowls — not quite alone, after all — but in her deaf-blind misery, a ragged ball of need. Food, water, toileting, occasional scratch behind the ear — but not too much, or she’ll scratch back. A living being to keep him going, when deserted by the creatures of his heart. But such a sad recompense, from so long and fruitful union! He strains at the glassy pane, yanks it open just a chink — then collapses in the grandfather chair, depleted by the feat. A low whistle through the crack; a zephyr lifts the wispy curtain, brings the scent of oranges and tea, a hint to Leonard Cohen — again, productive to the end. “Suzanne” on the record player, but no strength to make that walk across the room to replace the needle. Instead he leans down, picks up the book of poetry left just in reach, squints his eyes to draw out the words.

A rattle in his chest! more than a tickle; more like the frenzied stabs of a baby griffin shattering its prison shell. The shock of sensation rocks him, throws the book across the room, as he grips his heart to feel the knocking and rumbling within. Through skin paper thin protrudes the jabs of a creature desperate to escape. “What is this?” he gasps through pain, unable to control the unruliness within — as talons tear, fierce and wild, a primitive anima clamouring for release. “For too long you used me — see me now!” it howls, as he rips open his chest and pours the dark clawed angel to the floor, savage and heaving, beating the black feathers of its blood-encrusted wings.

Building Castles in the Air — Smart Legal Contracts
By: Lorens Huculak
Tags: Internships, Blockchain, Innovation, Internet of Things, Smart Contracts

🤖 The Technicals

Legal Contracts

In order to innovate traditional agreements, one must first understand the definition of a contract. The Draft Common Frame of Reference (DCFR) is a draft for the codification of the European contract law and related fields of law and it states the following:

Article II. 1:101: Meaning of Contract and Juridical Act

A contract is an agreement, which gives rise to, or is intended to give rise to, a binding legal relationship or which has, or intended to have some other legal effect.

In general, a contract can be concluded if the following points are met:

At least two parties are involved — natural persons or legal persons. There is an intent of the parties to have legal consequences. A sufficient agreement is reached.

Next, let us compare its properties with those of the novel technology, Smart Contracts.

Blockchain and Smart Contracts

A Smart Contract is a computer program that allows for credible transactions without third parties. These transactions are trackable on the blockchain and have an immutable character. It is, in essence, a piece of code, designed to perform pre-defined actions when certain conditions are met.

The irony of the situation is that it is neither smart nor a legally binding contract. The protocol is subject to the quality of the written code. It can contain bugs and is irreversible. It is, however, able to self-execute transactions, which is why it is a core building block of a Smart Legal Contract.

Smart Legal Contracts

Smart Legal Contracts are legal agreements that can be read and executed by a machine. It contains the legal prose of a lawyer, a digital signature and finally hashes the document.

The Accord Project’s open source technology enables the creation of legally binding contracts that become ‘self-aware’ through connection to external data sources and other information systems. This enables automation of transactions and other contract management processes.

They provide open source software tools that form a triangle of model-logic-language of functionality. The combination of these three elements allow for contract templates to be edited, analysed, queried and executed.

Tags: Trading, Ethereum, Cryptocurrency, Data Science, Machine Learning

Looking into the future is always exciting, especially if it’s the future of markets…

So now we are ready to test our engine. As a simple example we will describe 3000+ experiments with following settings:

Currency pair: ETH USDT Candle time interval: 1 hour Exchange: Binance Y labels: If in the next period the price has grown for 3% or more we put “buy” label, if the price went down for 1% we put “sell”, else “wait” label Neural Network Architecture: Feed Forward Seeds: 0 -100 Epochs: 1–34 Class weights: for class “buy”: 3, “sell”: 8 Test set start date: 11.14.2018 Test set end date: 2.19.2019 Trading indicators: MACD(moving average convergence/divergence), RSI (relative strength index), Ichimoku Cloud, OBV (On-balance volume), SR(support and resistance), BB(Bollinger Bands), DMI( Directional Movement Index)

Results:

So after running experiments in these settings, the best model we got was able to make almost 35% profit in 3 months. Out of 3414 experiments, only 307 or 0.9% yielded profitable models, detailed results can be found here. History of trades of the most profitable model is here.

The experiments we ran is like 0.0000000000001% of the total amount of all experiments that possibly can be conducted. This is not much, but we still were able to get good results.

What do you think about the results? How can we improve them? We appreciate your feedback. See you in a week.

Stop the riots

mindless violence

and shower the nation

India is witnessing serious unrest. Riots began in December with the passing of a law that makes non-Muslims from some neighboring nations eligible for fast-tracked citizenship. Many Muslims say it is discriminatory.

Soft, golden morning ray touched me with a welcoming song of birds

chirping from the nearest tree branches,

my blanket-covered body asked me to stay in bed,

mind decided otherwise

the brush and the toothpaste synced event ended as usual

eyes sharpened, hairs synchronized

and I looked at the mirror for one last time,

before the morning buzz hits me hard

I saw

a human standing

mirrored, confused but

smiling inside the glass canvas

amusement in his eyes

struggles of life here and there, with

living moments beaming out

with puzzles and questions that he was about to ask

the set staged for a conversation

then I realized

I can’t talk to my past,

my photons that stoke the mirror and bounced back as a human form

a nanosecond late to my eyes

his questions can reach out to me

my answers won’t make it to the past.

A new friend is page ten

through gentle forest

on a perfectly warm day.

A new friend feels like

a leaf bud unfurling

the graze of soft-tipped balsam fir

a transcendent sea-foam green

like the monarch’s chrysalis

or avocado flesh.

A new friend is proof

that we live well

amid hopeful minutia

like harvesting baby lettuce

Client vs Customer

What’s the difference?

A customer is somebody who buys goods, e.g. in a supermarket. Or somebody who buys services like at a hairdresser.

A client uses professional advisors and services. Accountants, architects, attorneys, consultants, and sex workers have clients.
Marking Yourself
By: Kittie Phoenix
Tags: Mark Of The Beast, Biblical Prophecy, End Times

However, Revelation is a prophetic book. It is designed to warn the faithful (and not-so-faithful) about things to come. But things to come is a future time — a time known only to God the Father. Even Jesus did not know the complete timeline (Matthew 24:36). Many things are hidden in imagery and figurative language.

If we think we are close to these times, what should we do?

First, as believers, we should have peace. We know the Lord, and we know He will keep and protect us. During hard times, He will lead us. He will give us the path to go.

Most sources believe the mark will not come until after the Rapture. At this point, I don’t understand Rapture well enough to know whether it’s a pre-trib, mid-trib, post-trib thing. I don’t think I have to. I just have to, after believing Jesus is Lord and making Him Ruler of my Heart, believe that He is able to do this.

What about about our non-believing family and friends?

First, inspiring fear and panic will score us no points. We should be wise as serpents as well as innocent as doves. We should recognize that Biblical prophecy is scary, and it can be even more so to those who do not believe and are either avoiding the Lord’s conviction or hearing the enemy’s condemnations.

Second, with the Lord’s help, we should be examining our motives and actions. We should be living in a way that wins the respect of outsiders; this includes non-believers with whom we are acquainted (Colossians 4:5, 1 Thessalonians 4:9–13).

This is the truest, best response for those who love the Lord and are called according to His purposes.
MPExplained: Trading Position Tokens
By: Collins Brown
Tags: Blockchain, Bitcoin, Ethereum, Cryptocurrency, Crypto

Let’s go through a few scenarios where the price of BTC changes.

Scenario 1: BTC goes up from $9,000 to $10,000, and we trade out of our position

Price of Long Token = Current Price - Price Floor Price of Long Token = $10,000 - $8,000 = $2,000

We can sell our long Position Token for $2,000, profiting by $1,000 since the price of BTC (the reference asset) went from $9,000 to $10,000.

The token initially cost $1,000 and represented exposure to $9,000 of bitcoin, implying 9:1 leverage.

If we initiated this trade in the spot market, then we would have been able to purchase just 0.111 BTC for $1,000 ($1,000 / $9,000), resulting in a gain of only $111.11 (0.111 BTC x ($10,000 - $9,000)), rather than $1,000 ($10,000 - $9,000).

Scenario 2: BTC goes down from $9,000 to $7,000, breaching our price band

Price of Long Token = $0

For a long Position Token, if the price of the reference asset falls below the Price Floor, then the token is worthless. In this example, the price of BTC (the reference asset) is $7,000, which is below the Price Floor of $8,000.

As a result, all BTC/DAI 6/30 Position Tokens go to settlement. As a long token holder, we receive our maximum loss, while the short token holders receive their maximum gain.

It is important to note that even though BTC is trading at $7,000 ($1,000 below the Price Floor floor) we only lose the $1,000 we initially paid for the position (when BTC was trading at $9,000) since $1,000 was our maximum possible downside. This concept is covered in more detail in our previous post.

After settlement, all tokens can be submitted to the smart contract for a return of collateral.

Scenario 3: 28 days have elapsed since contract creation, so our position expires

When a Position Token reaches expiration we use an oracle to bring price data onto the Ethereum blockchain. We are currently using CoinCap to aggregate the price of BTC from an index of 70+ exchanges. This will set a final price for long and short Position Tokens.

For example, let’s say after 28 days the contract settles at a BTC price of $8,300.

Price of Long Token = Current Price - Price Floor Price of Long Token = $8,300 - $8,000 = $300

We paid $1,000 for the token, but it’s now worth $300, so our loss is $700

Let’s consider for a moment the short Position Token. Remember from our previous post the following formula:

Price of Short Token = Price Cap - Current Price

So the value of our short token:

Price of Short Token = $12,000 - $8,300 = $3,700

After settlement, all tokens can be submitted to the smart contract for a return of collateral based on these prices.
Vue Router 4–Scroll Behavior

Vue Router 4 is in beta and it’s subject to change.

To build a single page app easily, we got to add routing so that URLs will be mapped to components that are rendered.

In this article, we’ll look at how to use Vue Router 4 with Vue 3.

Scroll Behavior

We can change the scroll behavior with the Vue Router.

To do that, we add the scrollBehavior method to the object that we pass into the createRouter method.

For example, we can write:

<!DOCTYPE html>

<html lang="en">

<head>

<script src="https://unpkg.com/vue@next"></script>

<script src="https://unpkg.com/vue-router@4.0.0-beta.7/dist/vue-router.global.js"></script>

<title>App</title>

</head>

<body>

<div id="app">

<router-view></router-view>

<p>

<router-link to="/foo">foo</router-link>

<router-link to="/bar">bar</router-link>

</p>

</div>

<script>

const Foo = {

template: `<div>

<p v-for='n in 100'>{{n}}</p>

</div>`

};

const Bar = {

template: "<div>bar</div>"

};

const routes = [

{

path: "/foo",

component: Foo

},

{

path: "/bar",

component: Bar

}

];

const router = VueRouter.createRouter({

history: VueRouter.createWebHistory(),

routes,

scrollBehavior(to, from, savedPosition) {

return { left: 0, top: 500 };

}

});

const app = Vue.createApp({});

app.use(router);

app.mount("#app");

</script>

</body>

</html>

We return an object with the left and top properties.

left is the x coordinate and top is the y coordinate we want to scroll to when the route changes.

to has the route object of the route we’re moving to.

And from has the route object we’re moving from.

Now when we click on the router links, we move to somewhere near the top of the page.

savedPosition has the position that we scrolled in the previous route.

We can use the savedPosition object as follows:

<!DOCTYPE html>

<html lang="en">

<head>

<script src="https://unpkg.com/vue@next"></script>

<script src="https://unpkg.com/vue-router@4.0.0-beta.7/dist/vue-router.global.js"></script>

<title>App</title>

</head>

<body>

<div id="app">

<router-view></router-view>

<p>

<router-link to="/foo">foo</router-link>

<router-link to="/bar">bar</router-link>

</p>

</div>

<script>

const Foo = {

template: `<div>

<p v-for='n in 100'>{{n}}</p>

</div>`

};

const Bar = {

template: `<div>

<p v-for='n in 150'>{{n}}</p>

</div>`

};

const routes = [

{

path: "/foo",

component: Foo

},

{

path: "/bar",

component: Bar

}

];

const router = VueRouter.createRouter({

history: VueRouter.createWebHistory(),

routes,

scrollBehavior(to, from, savedPosition) {

if (savedPosition) {

return savedPosition;

} else {

return { left: 0, top: 0 };

}

}

});

const app = Vue.createApp({});

app.use(router);

app.mount("#app");

</script>

</body>

</html>

When the savedPosition object is defined, we return it.

Otherwise, we scroll to the top when we click on the router links.

Now when we scroll to the links, we’ll stay at the bottom of the page.

Conclusion
Super Easy Compositional UICollectionViews in Swift
By: Eric Yang
Tags: Programming, iOS, Swift, Mobile, Technology

1. The Old Days of Using Nested UICollectionViews

Photo by Joanna Kosinska on Unsplash

Through the years, iOS developers strive to achieve cross-scrolling pages like Apple does within their App Store. Developers are impressed by how Apple mixes the horizontal scrolling and vertical scrolling within the same page.

Before iOS 13 was released, there was only one way to achieve this: wrapping the UICollectionView instance within the UICollectionViewCell of another UICollectionView . It certainly can be within an UITableViewCell ; it just depends on whether you’re using an UICollectionView or UITableView as the parent view. But normally UICollectionView is more popular, as it is more flexible for a customised layout. The internal UICollectionView implements horizontal flow layout, while the outer UICollectionView implements vertical flow layout or vice versa.
[Trading Education] Ranging & Trending market conditions-What are they?
Tags: Trading, Bybit Articles, Bitcoin, Cryptocurrency

Written by Dhiresh Dabasia

This article will introduce the concepts of ranging conditions and trending markets, as well as how they can be defined, identified, and used to enter a trade.

Ranging conditions:

Ranging conditions are defined by the price moving between short, or medium, support and resistance level, meaning it will go up and down between these two levels and display horizontal movements, thus stabilizing. Trend traders cannot profit from such a market, but range traders would as they would continue to assume that the price would trade through the same levels many times and enter traders accordingly. An example of a ranging pair is shown below.

In the chart above, the price trades mostly within the blue box displayed. As the cryptocurrency market is highly volatile, range trading is strongly discouraged. Traders should not take buy or sell trade orders when the market enters such ranging conditions on timeframes below and including 4H.While ranging conditions are far from ideal for taking trades, if a setup presented itself before the price entered such conditions it is imperative to remain patient, keep the position and place stop losses strategically whilst managing risk properly.

It is important to know a ranging market is one which it stuck in a horizontal box range. It should not be mistaken with one which is in upward or downward channels as these conditions are described as trending.

Trending market:

As opposite to a ranging market, a trending market presents either higher highs and higher lows, also named bullish market, or lower highs and lower lows, also named bearish market. Trending markets are easy to identify as they have a clear direction, going either up or down, and give traders great risk/reward trades. An example of a trending market is shown below:

In the example above, clear lower highs, shown by the red arrows, and lower lows, shown by the green arrows, are visible, which is characteristic of a bearish market. Furthermore, as the pair is trading within a falling wedge and the pullbacks occur after the lows, traders should only take shorts whilst the market remains in these conditions.

We hope you have learned a lot in today’s article and will integrate it in your trading strategies to enter the best trades possible. Make sure you follow us for more content!

Chinese Government Now Aiming to Ban Centralized Cryptocurrency Trading

A senior official in the People’s Bank of China (PBOC) is campaigning for the ban of centralized cryptocurrency trading. According to Reuters, an internal memo from a government meeting shows that PBOC Vice Governor Pan Gongsheng claimed that the Chinese government would continue to apply pressure to the virtual currency trade to “prevent the build up of risks in that market.”

New Tax Law Closes Many Loopholes for U.S. Cryptocurrency Investors and Owners

Section 1031 of the new U.S. tax code changes how the U.S. government taxes “like-kind exchanges,” which affects cryptocurrency investors. According to the Motley Fool, cryptocurrency investors who sell a digital coin or token to buy another on or after January 1, 2018 will have to report the sale of the original coin or token as a capital gain or loss on their federal tax returns. In addition, any transaction for a service involving cryptocurrencies (not just exchanging for another cryptocurrency) technically requires payment of a capital-gains tax.

Researchers Conclude Single Actor’s Fraudulent Activity on Mt. Gox Increased Bitcoin Price from USD 150 to USD 1,000

A recent journal article from the Journal of Monetary Economics has concluded that “a single actor likely drove the USD/BTC exchange rate from USD 150 to USD 1,000 in 2 months.” Researchers Neil Gandal, JT Hamrick, Tyler Moore, and Tali Oberman examined suspicious trading activity on the Mt. Gox Bitcoin currency exchange. According to the researchers, the single actor fraudulently acquired 600,000 Bitcoin valued at USD 188 million on Mt. Gox. The exchange rate increased an average of four percent on days when suspicious trades took place, whereas the rate declined slightly on days without the suspicious activity.

80 percent Of All Bitcoin Have Been Mined

80 percent of the 21 million total Bitcoin have been mined. As reported by Inverse.com, cryptocurrency analysts are divided on whether the value of Bitcoin will rise after all Bitcoin are mined. The mathematics needed to properly record blocks is become harder as the amount of Bitcoin in circulation gets closer to 21 million. Consequently, many expect the rate of Bitcoin mining to decrease.
