The Power of Bayesian Inference estimated using PyMC3
By: Marcus Richards Ph.D.
Tags: Bayesian Statistics, Inside Ai, Monte Carlo Method, Pymc3, Python

Ref: Jupyter Notebook and GitHub Repository

The beauty of Bayesian methods is their ability to generate probability estimates of the quality of derived models based on a priori expectations of the behaviour of the model parameters. Rather than a single point-solution, we obtain a distribution of solutions each with an assigned probability. A priori expectations of the data behaviour are formulated into a set of Priors, probability distributions over the model parameters.

The following scenario is based on Thomas Wiecki’s excellent article “GLM: Robust Linear Regression”¹ and is an exploration of the Python library PyMC3² as a means to model data using Markov chain Monte Carlo (MCMC) methods in Python, with some discussion of the predictive power of the derived Bayesian models. Different priors are considered, including Normal, Student-T, Gamma and Gaussian Random Walk, with a view to model the sample data both using generalized linear models (GLM) and by taking a non-parametric approach, estimating observed data directly from the imputed priors.

Sample Data

Our sample data is generated as a simple linear model with given intercept and slope, with an additional random Gaussian noise term added to each observation. To make the task interesting, a small number of outliers are added to the distribution which have no algebraic relationship to the true linear model. Our objective is to model the observed linear model as closely as possible with the greatest possible robustness to disruption by the outliers and the observation error terms.

Normal vs Student-T priors

We compare models based on Normal versus Student-T observation error priors. Wiecki shows that a Student-T prior is better at handling outliers than the Normal as the distribution has longer tails, conveying the notion that an outlier is not to be considered wholly unexpected.

True linear model and Ordinary Least Squares (OLS) regression

We start with a simulated dataset of observations of the form y=ax+b+epsilon, with the noise term epsilon drawn from a normal distribution. Here we 1) create observation values in the range x from 0 to 1.5, based on the ‘true’ linear model, 2) add test outliers and 3) extend the x axis from 1.5 to 3.0 so we can test the predictive power of our models into this region.

In the predictive region we have used numpy.MaskedArray() function in order to indicate to PyMC3 that we have unknown observational data in this region¹⁵.

It is useful to visualize the simulated data, along with the true regression line and ordinary least squares regression.

The Seaborn library allows us to draw this plot directly⁴, and we can also set a ‘robust’ flag which calculates the regression line while de-weighting outliers.
Mr. 2k Is In The Building!

Tags: Followers, Satire, Poetry, Humor, Fans

I hit two thousand “fans” today

That might make most people say, “Hurray!”

But I know that many were just making a play

To get me to follow them back

But I don’t play follow for follow

A practice that I find quite hollow

I’d rather have a stale marshmallow

Then a follow from that silly hack

I know who actually read my stories

At least the ones who clap

They’re nowhere near two thousand strong

My Stats attest to that

But I sure am glad to see their names

The ones who read instead of playing games

It’s genuine readers that I recommend

I appreciate them all, my Medium friends

They are the ones who fill my heart

More than any number on a chart

I may sound like a real humbugger

But I’ll take real readers over any number

Still, I will celebrate this new milestone

Perhaps humble brag about it on my phone

People will think I am well-known

Until they learn the truth and my cover’s blown

2k

Today

“He’s no Hemmingway”

That’s okay

I’d rather be me anyway

Thank you for reading, Medium friends!

Stark Raving Stories

Women’s Rights are and should be the priority

Image by Dimitris Vetsikas from Pixabay

Thee Quest-Human Rights

With all the talk about covid 19, we often forget that there are so many wonderful problems in the world right now. I know that I am sarcastic, but we need to take some of the attention away from covid and share other views of the world.

I believe that women's rights are so important that we leave our guard down too often when we think about it.

Yesterday I read two articles from an incredible woman and want to share them with you. Her name, you guessed it, is Stark Raving. She brings many subjects to the forefront and her views are great “food for thought” if you are a woman or part of the LGBTQ community.

I am Trans and I have been looking at women from the inside of a man’s body for over 60 years. I have learned to love them and love men also. Understanding their world has become an obsession. Thee Quest wants to share views from all people and Stark brings to the table two varying ways that look at women.

The following stories are important. If you are too busy, come back later or look her up on her medium page. I appreciate your attention.

Men and women are equals.

We Are Voluntarily Pausing Our Pre-ICO Offering
By: Supplybloc Technology
Tags: Token Sale, Polymath, Announcements, Financial Regulation, Blockchain

SupplyBloc, Inc. is temporarily pausing our pre-ICO to preemptively prepare our SUPX Token Sale to be compliant with the U.S. Securities and Exchanges Commission (SEC).

The concerns and discussions regarding SEC regulation within the blockchain and cryptocurrency communities have been equally confusing and intriguing as of late. SupplyBloc remains hopeful about the potential positive effects that the ongoing and inevitable regulatory and industry transformations will likely have on the blockchain and crypto spaces as a whole.

Migration to Security Token Offering (STO)

SupplyBloc is proactively taking the steps to become SEC compliant by issuing a Security Token via an STO. STO’s are quickly becoming the safer, more secure, and ultimately more enduring way to raise capital with a token sale.

The primary difference between an STO and an ICO is that unlike utility tokens, security tokens are considered financial securities that are backed by assets with inherent value such as a company’s profits or revenue.
Thanksgiving Turkey Cook Times

On Thanksgiving last year, we spatchcocked the turkey, and it cooked way too quickly. None of the delicious sides were done cooking by the time the turkey started cooling. Which seems like the opposite problem of most of my previous holiday dinners.

Inspired by this blunder, I looked at how different cooking methods and proteins affect time in the oven. All examples are 12 pounds for comparison. Oven temperature and cook time varies.

The National Black Chamber Of Commerce And humble ventures Are Providing $150,000 To Black-Owned Bars And Restaurants

Accepting Applications Now

Early-stage effects of COVID-19 and lockdowns have disproportionately hit minority businesses. Analysis from the National Bureau Of Economic Research reveals 41% of Black business owners disappeared in April. Additionally, according to a Global Strategy Group survey, just 12% of Black and Latino business owners who applied for aid received what they had asked for. Twenty-six percent said they received only a fraction of what they had requested. Half say they anticipate closing in the next six months.

“Supporting Black-owned restaurants is one practical, actionable way to stand in solidarity with the Black community now, and always.”- Bon Appetit

Only 130 Black-owned restaurants received PPP loans over $150,000, according to a report by Restaurant Business Online. The data highlights the systemic neglect of minority business owners and the dire situation many are facing alone, which is why the National Black Chamber of Commerce (NBCC), in partnership with humble ventures, is announcing financial relief assistance to Black-owned bars and restaurants.

Together, we will be awarding $150,000, in total, to Black-owned businesses through the program/application process outlined below:

Selection Criteria

NBCC and humble ventures will be supporting Black-owned bars and restaurants impacted by COVID-19. Two levels of approvals will review completed applications before being accepted and awarded the amount.

Eligible businesses must be at least 51% Black-owned, registered with a physical United States address, have a bank account that accepts electronic payments, and have been in business for at least two years.

Applicants will be required to complete a form (one per business) requesting specific information including, but not limited to, ethnicity, contact information, and supplemental documents for proof of work. Acceptable award expenses will go towards payroll, personal protection equipment (PPE), PPE training and materials, technology upgrades, mortgage or rent payment, and operating expenses.

The donations will be dispersed immediately upon acceptance. The awards (lump-sum up to $2,000) will be sent electronically to the awarding business.

I Don’t Understand What You Mean by “Relationships Are Hard Work”

I Don’t Understand What You Mean by “Relationships Are Hard Work”

I can’t be the only one who has a fantastic time with my partner

Photo by Brooke Cagle on Unsplash

Nearly every article I see linked on Twitter or Instagram about relationships are about how they’re such hard work. How you have to put in 100% to maintain that relationship and love.

…I don’t get it.

I’ve been with my partner for over six years and we have lived together for more than three years. And I have never once grown tired of him. I have never once thought to myself “this is so hard, I feel like I’m working hard at this relationship.” Am I the outlier in this argument?

Is it wrong that I would genuinely rather spend an evening in with my partner than go out with a couple of girlfriends? Is it so bad that I actually like spending time with him? Is it unhealthy that he’s my absolute best friend? I don’t think so.

Yet every op-ed article about marriage or relationships would have me believe I’m the weirdo here.

Sure, we have our arguments. We have our tough spots. But they last minutes, at best. We are constantly communicating our feelings and letting each other know what is good or bad. I love him more every single day and I don’t think there’s any “work” behind that.

I was reading an article today about how relationships MUST require work in order to succeed. Joy Joses, the author, uses the analogy of a seed being put into soil and then put in a dark cupboard. She says that you wouldn’t expect it to grow and thrive if it were out of the sun and not watered, and you should expect the same with a relationship. You have to nurture a relationship in order for it to grow.

Here’s the thing: People aren’t plants. And even if they were comparable in the way that Joses explains, there are literally thousands of different kinds of plants, many of which actually do thrive in darkness and with little water or attention. Much like plants being different, I think every relationship is very different.

My relationship with my partner is vastly different than my parents, who are happily married, and even more vastly different than his parents, who have been divorced since he was four years old.

I don’t think there can be one recipe for a relationship. I think every single person is different and therefore every single relationship is different. Believe me, I’ve had my fair share of relationships that DID feel like work. We had to work to prioritize each other, we had to work to make time for one another, and there was work on both sides to communicate effectively.

Maybe I got lucky with my forever partner because all of that has come easily since day one.
Progressive Image Loading in React Native
By: Spencer Carli
Tags: JavaScript, React, Mobile App Development, React Native

Internet connection speeds are variable, especially when you’re working with mobile devices. As developers we often forget that many of our users are running our apps on less powerful devices and with slower internet connections than we are. Go out into the mountains and try to access your app and see how it performs.

One of the more expensive things in an app is the remote images you’re loading. They’re going to take time to load, especially if they’re large images.

Today we’ll build a component that allows us to:

Pass a full size image to display (just like a normal Image component) Pass a thumbnail image to display while we’re loading the full size image Automatically display a placeholder in the soon-to-be-downloaded image’s place to indicate that something will be there Animate between each state as we go.

Getting Started

To start create a new React Native app (via react-native init , create-react-native-app , or the expo cli) and add the following to App.js .

import React from 'react';

import { StyleSheet, View, Dimensions, Image } from 'react-native';



const w = Dimensions.get('window');



const styles = StyleSheet.create({

container: {

flex: 1,

alignItems: 'center',

justifyContent: 'center',

},

});



export default class App extends React.Component {

render() {

return (

<View style={styles.container}>

<Image

source={{ uri: `https://images.pexels.com/photos/671557/pexels-photo-671557.jpeg?w=${w.width * 2}&buster=${Math.random()}` }}

style={{ width: w.width, height: w.width }}

resizeMode="cover"

/>

</View>

);

}

}

That block of code simply displays an image. It's requesting an image from Pexels at 2x the size of the screen (we want big images so they load slowly) and the buster query param will help us not cache the image so we can fully see what's going on. You wouldn't want to do this in your actual app.

Feel the Pain

Like I said before — as a developer you’ve probably got a pretty decent internet connection.

Let’s change that.

If you’re on a Mac you can install a tool called Network Link Conditioner (here’s how to install it). I’m sure there is similar for my Windows and Linux fans (chime in below if you have tool suggestions).

It will allow you to simulate just about any network condition you need. Just remember to turn it off before you start trying to stream video.

Enable it and set it to the “3G” profile.

Network Link Conditioner

Here’s a comparison of the starter with Network Link Conditioner off vs. on.
Careful vs. Paralyzed
By: Jeff Yablon
Tags: Careful Vs Paralyzed, Carefulness, Analysis Paralysis, Business Process

The astronauts of NASA, including David Scott and … yes, that other fellow is first-man-on-the-moon Neil Armstrong … are very careful. They have to be; their missions wouldn’t work otherwise, and absent great care people would die. But Careful and Paralyzed are different things.

Do you know the difference?

Recently, I came across an article at Harvard Business Review that got me thinking. With the issue being perfectionists getting in their own way, the question becomes how businesses can avoid paralysis. And yes, it comes down to knowing — or at least being able to spot — the difference between careful and paralyzed. And often, that comes down to something incredibly simple:

Sometimes, “Good Enough” really is good enough.

Much as that thought — or at least the wording — bothers me, the idea is correct. There’s almost never such a thing as perfect. This idea has come up here before, both when HBR pointed it out relative to hiring, and here, when we spoke about laundry lists and hiring practices.

Sounds like a conflict, right? The trick is finding your happy place between perfect and not-perfect-but-perfect-for-task.

Careful And Paralyzed

I see this all the time. And it isn’t exclusively a business process thing or even just about business, at all. I know people — I’ll bet you do too — who just can’t make decisions. Pulling the trigger stops them in their tracks. Paralysis sets in. The line between careful and paralyzed becomes impossible to cross.

You’ll never get to the moon if you’re afraid of making mistakes

Those NASA guys got it. You’ll never get to the moon if you’re afraid of making mistakes — no matter how high the risk.

And that’s the big obstacle. Business change, business in general, and even well-designed business process all require a bit of guts. For many people finding the strength to trust yourself when it’s time to make hard decisions isn’t a natural thing.

Paralysis by analysis, to quote a trite-but-in-no-way-overused phrased.

I’d like to tell you there’s a set of exercises you can do to trust yourself more while simultaneously not scaring off your employees, vendors and customers. It’s not that simple.

Actually, it’s far simpler. As Nike famously said in an old ad campaign, Just Do It.

And as odd as this might sound … if you need a push … we’re here to help.

The Power of Secrets and The Lies Told to Keep Them

A perpetrator’s power is fractured by the truth.

In darkness the pledge was made

about improper acts

abusing trust and power

With threats of consequences

of spilling the secret

to those who supposedly could not understand

But eyes not meant to see

also in secret held power

to fracture that pledge

Stories meant to cover-up

were undone by whispered half-truths

by a whistle half-blown

Fantasies of no wrong-doing

intended to save

corrupt relationships

More lies told to keep

the secret from hurting

those already hurt

Eyes not meant to see

or ears not meant to hear

or voices not meant to speak

Spoke

of what

was heard

Spoke

of what

was seen

The truth rained on the power

needed for more perpetrations

preventing more

Judgment made

sentence delivered

a community listened in horror

Of the perpetrations

held secret

no more

And the victim’s guilt

once massaged by the perpetrator

evaporated.
Stuffed Pain

Anyways it never hurt outside

It was inside where it existed

The never ending pain

Stuffed around dark corners

which kept getting darker

It kept peeking around,

for some tiny light to be seen

raising it’s tiny ears,

like some lost little puppy

eager for a faint sound.

Anticipation vs. Anxiety
By: Mike Vardy
Tags: Mindfulness, Productivity, Anxiety, Decision Making, Thoughts

Photo by dylan nolte on Unsplash

I don’t know why Carly Simon’s song “Anticipation” found its way into my head this week. But it did… and it got me thinking about the word.

The word “anticipation” originates from the Latin anticipationem, meaning “preconception, preconceived notion.” Its meaning has since shifted to “the action of looking forward to”, which I actually kind of like.

Sure, whatever you anticipate doesn’t always come out as foreshadowed, but the concept of anticipation seems to hold less fear in it than the idea of being anxious or feeling anxiety about something.

Anxious comes from the Latin anxius, meaning “solicitous, uneasy, troubled in mind.” There’s no question there are moments that we all feel anxious — some of us more than others and in some situations more than others.

But what if we channeled our energy and attention towards anticipation over anxiousness? What would that look like? What would that feel like?

I’m going to try this, reframing my thoughts around anticipation over anxiousness when I have no concrete idea of what to expect.

Maybe you should give it a try too.
You need 2 things for a successful monorepo
By: Jacob Bennett
Tags: Monorepo, API, Software Development

You should use monorepos. They help a project scale faster and keeps it sane as it grows. For it to really work, you must have 2 things: structure and rules.

Here are an opinionated structure and set of rules I’ve used successfully on about a dozen projects, the largest of which scaled to about 50 engineers. (Large enterprises need rules and structure too, but at that scale, it’s better to use dedicated tooling to manage the overhead of dealing with all of those engineers.)

Structure

You need 3 top-level directories: projects , lib , and tools .

├── projects/

│ ├── athena/

│ └── perseus/

├── lib/

│ ├── custom-orm/

│ └── error-definitions/

└── tools/

├── ci-scripts/

└── terraform/

projects

projects contains all of the deployable (loosely-defined) projects.

lib

lib contains shared code, or code that has the reasonable potential to be shared across different projects.

tools

tools contains all of the tooling around the application that’s not specifically part of the codebase. This is the perfect spot for a Terraform configuration or CI/CD scripts.

Rules

1. Everything MUST have a README

Every README SHOULD include, at a minimum:

A brief description of the project/lib/tool explaining what it is and does. For example, “Athena is a service for managing feature flags for arbitrary subjects.”

Any notable quirks (this should be close to the top of the README). For example, “This project depends on _________ library which is only available on Ubuntu 18.04 and later.”

A walkthrough of how to use the module from scratch. There SHOULD NOT be any initiated knowledge required beyond some common fundamentals (e.g. Docker, bash commands, etc.). For example, “To install custom-orm run pipenv install git@github.com/org/monorepo#egg=lib/custom-orm in the target project.”

Here’s a minimum example README for Conductor, an imaginary project.

2. Projects MUST NOT depend on other projects

If you want to share code between projects, use a lib . Everything in projects MUST stand independent of each other.

3. The repo MUST use trunk-based development

This one is mandatory for most competent systems, though you could argue for an alternative branching method if that works for you. I’ve found that trunk-based is easiest when working across multiple teams, especially on young projects.
My Practice

My Practice

Recursive Visualization Design

Evolution

In case study 0, I talked about my past practice of making medical visualizations for doctors and researchers. I view the approach to designing that I have now to be a direct and logical outgrowth of that work, but there are some key evolutions that bear examination. There are four high level or meta skills that I regularly employ as a designer: translation, distillation, interpretation, and visualization. Comparing myself at the end of this period of study in design for interactions to myself during my medical illustration years, my practice still rests on the same four meta skills. What has changed is the proportion of each in relation to each other.

When I was purely an illustrator, my job was to grasp the concepts that the doctors wished to express and figure out how to materialize them in a comprehensible visual form. The relationship was uni-directional, linear, and involved two distinct phases: the doctor would take their understanding and give it to me, then I would translate that knowledge into a visual form. But a funny thing happened when I did this: the doctors would say to me, often with a slightly puzzled expression, ‘you know I really understand this concept in a new way after working with you to express it’. I’ve learned in life to pay close attention to anomalies, to the unexpected. A new feedback loop, or potential for a feedback loop, was just beginning to reveal itself to me. I saw for the first time that my work as a designer could feed back into the process of scientific research and spark new understanding in the researchers minds.

I came to CMU to see if I could begin to understand that feedback loop. After three years of study, my design process has gone from linear and mostly translation plus visualization, to a recursive process characterized more heavily by distillation and interpretation which feeds periodically back into the minds of researchers. If I were to characterize these two processes in questions they would be:

primordial process ‘What does this data look like visualized?’

evolved process ‘What visual forms can I feed back into the research process to catalyze new moments of insight?’

Recursive Visualization Design

When we think of a repeated action in design, we most commonly think of iteration. A designer taking an idea or direction, and repeatedly making new, improved, more sophisticated, more sensitive, and more fully realized versions of a design. This is not what I mean when I say that I recursively design visualization inputs into a research process. To be sure, I iterate on visualizations to drive them forward. But that repeated designing is a forward drive that is bent back into the stream of research to come in contact with the scientists minds and thoughts. Iteration is about repeating toward a design objective. Recursion is about sparking new ways of knowing in the minds of my colleagues through sensitive design choices.

Must-Know Statistics for Data Scientists

The most important & fundamental concepts in statistics

Beginners usually ignore most foundational statistical knowledge. To understand different models, and various techniques better, these concepts are essential. These work as baseline knowledge for various concepts involved in data science, machine learning, and artificial intelligence.

Here is the list of concepts covered in this article.

Measures of central tendency Measures of spread Population & sample Central limit theorem Sampling & sampling techniques Selection Bias Correlation & various correlation coefficients

Let’s dive in!

1 — Measures of central tendency

A measure of central tendency is a single value that attempts to describe a set of data by identifying the central position within that set of data. The three most common values used as a measure of center are,

— Mean is the average of all the values in data.

Mean of ’n’ data values

— Median is the middle value in the sorted(ordered) data. Median is a better measure of center than mean as it is not affected by outliers.

— Mode is the most frequent value in the data.

2 — Measures of spread

Measures of spread describe how similar or varied the set of observed values are for a particular variable (data item). Measures of spread include the range, quartiles, and the interquartile range, variance, and standard deviation.

— Range is the difference between the smallest value and the largest value in the data.

— Quartiles divide an ordered dataset into four equal parts, and refer to the values of the point between the quarters.

The lower quartile (Q1) is the value between the lowest 25% of values and the highest 75% of values. It is also called the 25th percentile.

The second quartile (Q2) is the middle value of the data set. It is also called the 50th percentile, or the median.

The upper quartile (Q3) is the value between the lowest 75% and the highest 25% of values. It is also called the 75th percentile.
One Small Step for a Future Astronaut

A random act of kindness can change someone’s life. When Marissa Valencia, a fourth grader at Brea Country Hills Elementary School, received a Random Act of Helpfulness from Honda Motor Company, she took one step closer towards her dream of becoming an astronaut.

Valencia was given an opportunity to attend Space Camp at NASA’s Marshall Space Flight Center, located in Huntsville, Ala., by Honda’s Random Acts of Helpfulness, a regional advertising campaign dedicated to performing various community services and granting gifts to Honda consumers.

Valencia attended Space Camp from Sept. 1–5. Throughout the course of the program, she underwent several astronaut training activities, such as building and launching model rockets and using a G-force simulator, which controls the force of gravity upon the person inside the centrifuge. She noted that one of her favorite parts of the camp was taking part in a mission control where she had to monitor oxygen levels and solve an issue of a mock astronaut. The overall experience made Valencia “feel like a real astronaut.”

“I am so thankful to Honda for this,” Valencia said. “I’ve always loved looking at the moon and the stars. I got to live my dream of space camp.”

She was specially selected to participate in the space program after Columbia Memorial Space Center’s STEM Club in Downey, Calif. referred her to Honda. Valencia was then told that she’d be interviewed for a documentary about kids that love space by a Honda employee. When it was revealed that the “documentary” was actually for a commercial, Valencia was astonished as it was a “total surprise.” The commercial is currently being broadcast on television.

“I want to be the first woman to touch the moon,” Valencia said in her interview with Honda. “No ifs, ands, and buts — I’m going to be an astronaut.”

Not only was Valencia overjoyed with the surprise, but her parents were delighted as well.

“I guess Honda wanted it to be a surprise, using the excuse that it was a documentary. There was no script so everything said was all genuine,” Nina Valencia, Marissa’s mother, said.

Valencia continues to pursue her dream of becoming an astronaut upon her return from NASA’s Space Camp. She is determined to see space with her own eyes in the future.

This is for java programmers who want to use java “Collections framework” without googling it again and again.

Queue <Integer> myQueue = new LinkedList<Integer>(); Wait, what? ( Why not “new Queue<Integer>()” ?)

If this is the first question raise in your mind then you are not the only one and this story is for you. After reading this story you will have fundamental concepts behind the java Collections Framework.

Here I will be answering following questions :

What is java Collections Framework? And why should I care? How is it designed and why it is designed like that? Why is Map separated? Why Generics in Collections Framework? or What is that angular bracket (<,>) thingy? Can I create my own Collection? And the question in the start of the story.

Let’s Begin!

The java.util package contains all the interfaces, abstract classes and classes of the Collections Framework.

It is a framework to manage and work with groups of objects.
Why a Smartphone is a Busy Parent’s Best Friend
By: Paper Pinecone
Tags: Money, Children, Daycare, Smartphones

When you become a parent, your notion of what it means to be busy can be completely uprooted. It can feel nearly impossible to get even half of your daily itinerary finished. Between scheduling appointments, making meals and returning messages, you may have trouble keeping your head on straight. However, there’s something in your pocket that might be a great help. These reasons will help you realize how useful a smartphone can be for a busy parent.

Awesome for Scheduling

One of the hardest parts of having a lot to do is staying on top of every item on your to-do list. Individually, these items tend to not be very difficult, but keeping track of everything can be. Thanks to smartphone apps, you can make schedules and set alarms that remind you when things are due, according to Shift. Interactive apps make creating to-do lists fun. You’ll also be able to realize just how achievable your duties are. These apps can boost your efficiency, which can help you to not procrastinate.

Relaxation

When you’re constantly barraged with demands and responsibilities, you can feel very overwhelmed very easily. Smartphones won’t completely eliminate stress and, if not used properly, can add to it. However, if you find soothing apps, such as ones based in meditation, you can give yourself a break from the tension. You can also opt to mute notifications for certain apps so that you aren’t feeling so overwhelmed by messages and alerts. Just because others feel like they have to be available to everyone 24/7 doesn’t mean you have to be.

Helps Manage Your Finances

Not so long ago, if you had no time to make a budget or otherwise figure out your finances, it likely took a large chunk out of your schedule. Now, thanks to smartphones, you can take care of your budget or pay your bills with the click of a few buttons.

You’ve likely gotten so used to life with a smartphone that you’ve forgotten about just how convenient it is. Take the time to appreciate all the options these devices give you and how much time you save. Thanks to this and other technological advancements, you’ll be able to appreciate quality time with your family far more.

How to Easily Verbalize Any C Variable Type Declaration

Here’s a couple of pointers.

Part of what makes C incredibly powerful is its complex type declarations. These statements can become infinitely complex, making it a necessity that we know how to express them into plain English.

A sample complex C variable type declaration

Like in most things programming, this is done by merely following an algorithm.

1. Identify and Locate the Variable Name

This is typically a name within the type declaration that is not a reserved word.

2. Move Left to Traverse Pointers

From the position of the variable name, move left until you read an opening parenthesis, ‘(‘, or the start of the type declaration, exluding the left-most type. For every ‘*’ you encounter, add the term “pointer to” to the variable declaration.

3. Move Right to Traverse Arrays and Functions

Resuming from the end of step 2, move right until you read a closing parenthesis, ‘)’, or the end of the variable declaration.

If you encounter brackets, add “array of length {length} of“ to the type declaration.

If you encounter parentheses, there are three possibilities:

If the parentheses are empty, ‘()’, add “a function with unknown parameters returning” to the declaration. If the parentheses read ‘(void)’, add “a function with taking no parameters returning”. Otherwise, add “a function taking ({list param types}) returning”.

Repeat steps 2 and 3 until you have reached both ends of the variable declaration.

4. Recognize Final Type

Finally, add the left-most type to the variable’s type declaration. This is always a reserved type, struct, union, or class, or other pre-defined type.

Example

Imagine we want to verbalize the following variable declaration:

char (*(**foo)[3])[10); Step 1: "Declare foo to be of type"

Step 2: "pointer to pointer to"

Step 3: "array length 3 of"

Step 2 (repeat): "pointer to"

Step 3 (repeat): "array length 10 of"

Step 4: "char"

In the end, we find that

char (*(**foo)[3])[10);

means

Declare foo to be of type pointer to a pointer to array length 3 of pointer to array length 10 of char.

More Difficult Example

unsigned int (*(**(*foo)(int , volatile short ))[4][6])[8]; Step 1: "Declare foo to be of type"

Step 2: "pointer to"

Step 3: "function taking (int, volatile short) returning"

Step 2 (repeat): "pointer to pointer to"

Step 3 (repeat): "array length 4 of array length 6 of"

Step 2 (repeat): "pointer to"

Step 3 (repeat): "array length 8 of"

Step 4: "unsigned int

Declare foo to be of type pointer to function (int, volatile short) returning pointer to pointer to array length 4 of array length 6 of pointer to array length 8 of unsigned int.

Will euro save Eastern Europe?

Article: Will euro save Eastern Europe?

http://newsvote.bbc.co.uk/2/hi/business/7932770.stm

Comments: The article is about Poland but there have been a lot of talks in the Czech Republic about this topic recently as well.

There are some missing facts in the article. First a most notable one — the eurozone is not an optimal currency zone. You can argue that no currency zone is optimal (and you would be correct) but eurozone is — I think — just the opposite of an optimal one. Remember not only prohibitions that don’t allow East-Europeans to work in the EU15 but also different cultures and languages. It would take a lot of transition cost for — say — a Slovak to come to Finland and work there.

Second, I miss very much that the Euro is not an economic project but rather a political one. I can hardly imagine a monetary without a fiscal one. And I can hardly imagine a fiscal union without a political one.

There is no doubt whatsoever that Euro is a huge step towards a so much closer Europe. The East-European countries must ask themselves if they want such unification.

Third, it’s not been stated that floating of zloty and koruna and other currencies helps the economies cope with the turbulences better than a fixed currency regime.

Not to mention all the talks about which country will be the first to exchange the Euro back for their respective currency, not to mention that the eurozone is a club of debtors, not to mention that the government bonds in the eurozone are now being sold at very different prices and so on and so forth.

I mean the answer simply must be no — the euro won’t save Eastern Europe.
Doodletober Day 24

Things have been pretty busy for me. And it feels awesome. Fortunately I am learning the art of rest in an effort to manage my work/rest life.

I recently began a new role as Communications Director for a college. When I saw what Doodletober was on day 24, which just so happens to be business, I immediately thought of doodling this.

I’m so glad I was able to participate at least once in Doodletober. There was a period of time, a week and a half almost, that I didn’t make time to draw. THAT won’t happen again.

I was so happy to draw this and hope to contribute more along with more writing here on Medium.
I Gave Away Most of My Clothes This Year. Here’s What I Learned.

The week before March lockdown, I bought a green cocktail dress from Zara. I had been invited as a speaker at a charity dinner. All night, the slip under the dress kept riding up to my waist. By the time I got home at 2am, cold and wet in winter rain, my shoes had given me seeping blisters on my heels. I’ll spare you the gory details.

“Never again,” I cursed, “will I wear these stupid heels.”

And so, it happened. No more heels. Lockdown began one week later.

Since March 2020, I have been working from home in the same happy permutation of clothes every day. In other words, I have found my personal uniform. Some people call it a capsule wardrobe.
Who is FÜD?

Tags: Ucsd, Uc San Diego, Data Science, Optimization, Nutrition

Pronounced like food.

Geisel Library at UC San Diego.

We’re a group of four undergraduate data science students at UC San Diego who believe in the limitless potential of data science for social good. FÜD is for anyone who wants to eat healthy, but stay on a budget.

FÜD was created with communities who have limited access to healthy, affordable food in mind. The concept of maximizing nutrition while under the constraints of a budget ultimately sounded like an optimization problem to a group of math nerds like us. And we were right! It turns out The Diet Problem is one of the earliest and most well-known linear programming problem that involves optimizing a linear objective function (nutrition) that is subject to linear equality and inequality constraints (budget).

But, we asked ourselves how we could go beyond a simple optimization problem. We could take into account personalized body measurements, food allergies, weight goals, or the possibilities are truly endless.

The goals of FÜD are two-fold:

Research the “Optimum Meal”. What is the single most nutrient-rich meal you could create that would also minimize cost? Create an application that will help others make healthy food choices that fit within their budget.

If you’re interested in following our journey developing FÜD and researching nutrition, keep reading our blog and stay tuned!

Doner Kebaps-History and Memories
By: Somsubhra Banerjee
Tags: Food, Poetry, Fiction, Letters From Li, Literary Impulse

I remember my first bite of Doner Kebap(means “rotation” in Turkish, another word for that is çevirme, which is Turkish for “turning,” and the origin of the Arabic word “Shawarma”), in the streets of a foreign land, for the first time, and feeling a feeling that stayed with me.

The crunchy round bread, and the insides caressed with juicy chicken, the fried veggies, dripped in sauces and cheese, the flavors exploded in my mouth, but the first few bites almost seemingly disintegrated the structure in my hand. I fell in love with this dish, fully and realized how a basic dish, has become a full-blown lunch and dinner substitute for a lot of people because it’s cheap, healthy, filling, and at the same time, tasty.

When I explored, I found its roots lying way, way back during the Ottoman Empire when the practice of grilling meat that has been stacked on a skewer on a vertically rotating rotisserie grill was started. Although the original Doner Kebaps used the meat base as beef, the German Turks introduced a lighter version with chicken stuffed in it and it became widely popular. One of the famous Doner manufacturers in Germany, Mustafa, started experimenting further and one day he had some leftover vegetables he fried and added to the Döner along with cheese and lemon juice, and suddenly, he had invented the “Chicken Gemüse Döner” as we know it today: thinly sliced Chicken Döner meat, salad, tomatoes, onions, sauce, fried vegetables (potatoes, peppers, onions, etc.), and on top, crumbled Turkish white cheese and a squeeze of lemon. Mustafa’s shops are still there and is a crowd favorite, with people waiting for an hour to grab a piece.

Food is an integral part of our life, we won’t survive without it, and we spend quite a chunk of money on street and restaurant food, but I feel so good, when I see a family belonging to any strata of society enjoying bites of doner sandwiches, biting into a hearty meal, it really leaves a smile on my face, cause not every food is affordable and not every one can conjure food that is affordable and people like Mustafa, they somehow carved a way to enter the palette of every single person, even those who doesn’t have a whole lot of money to spend.

Dear Readers, did you also get a chance to munch on this food item, or do you know of some other street food , that you feel caters to a wide section of people? Do let me know in the comments, I would love to read about them.
