Evernym joins Hyperledger
By: Judd Bagley
Tags: Evernym, Identity, Blockchain, Hyperledger, Juddbagley

Today it was officially announced that Evernym has joined Hyperledger. It may strike readers familiar with our history as odd to learn that we’ve just now officially become part of the effort, since we are the inventors of Hyperledger Indy, one of the five Hyperledger projects. But this is how it’s worked out.

It might be worth reviewing the history of Indy.

Evernym was originally conceived as a top to bottom self sovereign identity (SSI) solution, encompassing everything from the application to a proprietary distributed ledger and everything in between.

Evernym contributed the code that has become the basis for Hyperledger Project Indy.

One of the core principles of SSI is the idea that a user’s identity must remain forever under her control and never be subject to the whims, weaknesses nor future prospects of any centralized entity. That being the case, the idea that even we be in control of the ledger to which users’ decentralized identifiers be written was inconsistent with our mission.

Thus, in the fall of 2015 we decided to find the best way to make the ledger truly independent, and recognized that the solution was to give it away. At the time we didn’t know exactly what that meant, apart from the fact that we would be turning the ledger into a global public utility upon which any entity (including future Evernym competitors) could build their own SSI applications.

The first step was to create the Sovrin Foundation and turn control of the ledger software over to this non-profit. Then, in the winter of 2016, the suggestion was made to turn the Sovrin code over to Hyperledger. A few months later, the process was complete and Hyperledger Project Indy was born.

Evernym Chief Trust Officer Drummond Reed (right) demonstrates a functioning, real-world SSI application built upon the Hyperledger Indy codebase at Consensus 2018.

‘Indy’, as an aside, got its name by virtue of its goal of achieving a truly independent distributed ledger for SSI applications. And indeed, it was the high value we place on its independence that kept Evernym from joining Hyperledger until now. We felt that our pride as the creators of Indy might cause us to exert inappropriate influence over its initial formative stages. And thus we maintained a very active interest in Hyperledger goings on, and even took steps to stimulate developer participation in the open source project, but otherwise kept our distance.

Today the Sovrin Foundation and Indy are standing quite capably on their own two feet, which helps us feel very comfortable participating in Hyperledger directly. As alluded to earlier, this puts us in the seemingly awkward position of working to promote an ecosystem serving not only our own applications but also those of competitors. Yet we find this gratifying as it will bring the world better SSI technology and speed along the process of broad-based adoption of the Sovrin protocols.

The possibilities awaiting Hyperledger and Indy are limitless. And we look forward to being part of the process.
She’s Dieting

She’s Dieting

In reference to my neighbor’s 13 year old daughter

Photo by Laura Chouette on Unsplash

At a Halloween gathering in the neighborhood, I mentioned to my neighbor how her daughter had blossomed. She told me her daughter was dieting.

Dieting? Really? Since when did a 13 year old start dieting?

Another neighbor nodded her head in agreement. Dieting, it’s going to last her whole life.

What? Since when do you need to diet your entire life? Did I miss the memo? When did it become the norm for women to diet?

Yes I’ve dieted. I’ve avoided carbs. I’ve tried Paleo and Keto. I’ve done a juice cleanse. But I didn’t start these ridiculous things until my 20s. At 13, I wasn’t focused on dieting. Over the years and failed diets, I’ve learned that “dieting” won’t produce results, having a healthy diet will.

A healthy diet is not dieting.

I have a 6 year old daughter so that explains my interest in teenage girls’ behavior. From birth, I have done my best to instill healthy eating habits for my daughter. I do not want her to body shame. I don’t want her to look at other girls with envy. I want her to make the right eating choices because it is healthier, not because she wants to be thin.

So far this is working. My daughter will pick fruit over cake. She wants cucumbers and tomatoes for her school lunch. She loves vegetables and meal prepping with me.

But will this change? Will the habits that I am working hard to instill in her disappear when she’s a teen? Will she follow the footsteps of the teenage girls who diet? I sincerely hope not.

Introduction to GraphQL
By: Felipe Cabezudo
Tags: API, Rest, GraphQL

REST vs GraphQL

The API-Rest architecture suggests that we should retrieve its data according to the routes we are requesting. Let’s say that you want to get the data for a user in our system with id=1. If we were to ask the API for this data, we would need to make a GET request to /users/1 to retrieve this user’s data.

Now, let’s assume that we have posts associated with this user, and we want to ask the API for both the user and its posts. Given how REST works we would have to query for the user /users/1 and its posts /users/1/posts , no big problem… BUT! We are making two queries to get the data we need, this means that we will have two roundtrips just to get a user and its posts. To solve this, we may have to create a new endpoint to get all the data at once, but we may still have prone issues.

Another big problem with the REST architecture is that we are prone to get more data than we want. Imagine that we have a profile view of our application. This view shows user data like name, nickname, bio, etc.

And posts basic information like title, date of creation, and the number of comments for each post. When we request the API for the posts information for this user we will get all the posts information (title, comments, body, replies, etc.). That’s good, but we only want to display the title, number of comments, and date of creation. So, therefore, the body information is unnecessary.

This problem is called Over-fetching, similarly, we could need certain post data that isn’t provided to us by the queried endpoint and have to make another request to a different endpoint to retrieve the missing data, this problem is called Under-fetching.

GraphQL, on the other hand, arises from the necessity to address both problems by implementing a single endpoint and a query language!

By defining types, queries, and mutations we can ask for whatever data structure and its nested associations in our schema with only a single query.

When Did You Know You Were Gay?

The answer to everyone’s favorite question

Photo from Pikist

If you’re queer, you’ve been here.

You’ve made a new straight friend. The two of you are starting to get closer — you’re not as thick as thieves, but you enjoy your time together.

Over a drink one evening after work, your new friend sits up straight, leans toward you, and says, “I have a question.” Their eyes glint with curiosity and their mouth is curled into a gentle, empathetic smile.

You know what’s coming, but you swallow a groan and ask, “what’s up?”

Your new straight friend grabs your hand over the grubby bartop and asks, “when did you know you were gay?” Then they exhale, lean back, and wait expectantly for an answer that will further them down the path toward Ally Enlightenment.

Law profs, solons begin legal battle vs. Anti-Terror Law Scientia Follow Jul 6 · 2 min read

The Anti-Terror Law is feared to be abused by the state to silence dissenters. Graphics by Tiffany Uy

Law professors and solons began filing petitions today before the Supreme Court to question the constitutionality of Republic Act № 11479 or the Anti-Terrorism Act of 2020.

A total of four petitioner groups took to the Supreme Court to physically file their appeals as of July 6. This comes just three days after President Rodrigo Duterte enacted the Anti-Terror Law despite wide condemnation.

A group of lawyers led by Atty. Howard Calleja was the earliest to file their petition. Calleja’s group already filed a petition electronically on July 4 but also opted for Padre Faura. Along with UP law professor Christopher Lao, former education secretary Br. Armin Luistro and civic groups Frontliners: Tunay na Bayani and Bagong Siklab Pilipinas, Calleja is asking for a Temporary Restraining Order (TRO) to halt the implementation of the Anti-Terror Law.

“This fight against Terrorism should not and should never be a threat to the fundamental freedoms of all peaceful Filipinos,” the Calleja Law Firm said in a Facebook post.

Albay Representative Edcel Lagman, the second petitioner, also asked for a TRO and sought to declare the Anti-Terror Law unconstitutional.

“No amount of assurances from law enforcement agencies that there will be no abuses in the implementation of the ‘Anti-Terrorism Act of 2020’ would mitigate the incidence of abuses because the law itself is abusive,” Manila Bulletin quoted Lagman.

Far Eastern University (FEU) dean Mel Sta. Maria and FEU law professors also questioned the constitutionality of the Anti-Terror Law, asserting that “the Anti-Terrorism Act, because of its patent nullity, will be a waste of vital financial resources especially during these trying times when the country is facing the COVID-19 pandemic.”

“The Act imposes State regulations that will stifle academic freedom by threatening to punish thinking and critical exchanges against the government that may be considered as terrorism,” the FEU Institute of Law said in their statement.

The Makabayan Coalition, led by former representative Neri Colmenares followed suit to physically file their petition against the Anti-Terror law, also seeking to declare the act’s unconstitutionality.

More petitioners are expected to take the Anti-Terror Law up at the Supreme Court, including the National Union of People’s Lawyers and former senior associate justice Antonio Carpio.

Unimpeded by the petitions, the Anti-Terror Law is expected to be in effect as early as July 18 provided that online publication in the Official Gazette website counts under Executive Order № 200 s. 1987.

Classifying Logos in Images with Convolutionary Neural Networks
By: Ann-Kristin Juschka
Tags: Machine Learning, Deep Learning, Convolutional Network, Udacity, Keras

While we will use the Rectified linear unit (ReLU) activation for hidden layers, the Softmax activation is used for the output layer to obtain a probability in the interval [0,1] for each output node. When “training the neural network”, the computer itself repeatedly optimizes the weights of the connecting edges so that the neural network’s output becomes as close as possible to the true logo classes.

When analyzing images, the amount of parameters in a classical neural net becomes very large: If an image measures 224 x 224 pixels and we record for each pixel its 3 RGB values as input, then we have 224 x 224 x 3 = 150,528 input nodes so that the neural net needs to optimize a large amount of weight parameters for all fully connecting edges. Further, the input nodes are arranged as a vector so the neural net does not know any regional patters of the image. These problems motivate Convolutional Neural Nets like this one:

In our example, the input nodes of the CNN are arranged in a 4x4 matrix shape. Then we define three 2x2 filters for the four input regions, where each region is only connected with the three correspondingly colored nodes in the hidden layer. Note that the 3 filters define 3 feature maps, which each detects a feature like a vertical, horizontal or diagonal line in the four regions. Or, in our use case, such a feature may be detecting a Starbucks, Burger King or Telekom logo.

As the weights parameters for the connections from the input layer to the convolutional layer are the same for each of the three filter, here we have only 2 x 2 x 3 = 12 weight parameters to be optimized in the training process thanks to fewer connecting edges and the CNN “understands” the regional contributions of the input data. Of course, in addition the training process optimizes the 12 x 9 = 108 weight parameters for the final fully connected output layer.

With respect to our concrete example of classifying small logos in images, a further advantage of CNNs is that they are translation invariant, i.e., they recognize logos in any region of the image.
Data 101: Metadata
By: Alexandra Northington
Tags: Data Analysis, Metadata, Data, Data Management, Data Science

What exactly does metadata tell you about data?

Context comes in a number of forms, each providing different color around a dataset. For now, we’ll focus on three key layers of metadata: user-contributed, derived, and provenance and lineage.

User-contributed: As the name suggests, this is metadata added by users who are familiar with the data. You can think of this as expert knowledge about the content in the form of annotations that help other users know what the data is and how to use it. This kind of information may include definitions of terms of columns or other details that may help to identify similar datasets.

Derived: With this type of metadata (mined from each dataset), we are essentially asking, “What can the data tell us about itself?”. Derived metadata can encompass information such as size, quality, and types of data, number of records, how often the data is updated, last modified date, anomalies, date ranges, and frequent keywords or tokens.

Provenance and Lineage: This third layer of metadata is tied closely to the creation, transformation, and usage of the data. It encompasses change history, social details around how the data is being used and applied across an organization, and dependencies: Is it a parent dataset? Is it used to create other datasets? Is it part of other datasets? This type of information is particularly important when trying to understand how a change in one dataset could have a much wider impact.

In subsequent posts we will explore additional layers of information such as ontologies and the mapping of the real world objects within datasets through specific relationships.

Should I Give Us Another Chance?. There can be no growth without some…
By: Ask Olive
Tags: Relationships, Ask Olive, Advice, Marriage, Love

Dear Olive,

I met my wife 20 years ago, in high school, and we have two kids. Five years ago while I was more focused on my work than I was on her, she met someone and has been cheating on me with this man since. I discovered this three years ago. First I wanted to leave, but I didn’t feel able. She didn’t want to leave either, she just wanted to live with me as a roommate and keep seeing that man.

I have never accepted this. At the time I didn’t know that she’d been in love with him for two years, and I thought it would end. I thought that by being more present and patient that I would win her back. After two years of enduring her relationship with him and seeing no progress, I decided it was time for me to try to forget about her.

But as soon as I met someone with whom things could get serious and asked her to leave, she began to show interest for me. Twice I left the woman I met for her, and twice my wife finally was not able to end things, on her side, with her lover. A few times she tried, but each time she’s gone back to him after a few weeks.

I know I should open my eyes, see that she doesn’t love me, and leave. Sometimes we seem to decide that it is over, but neither of us seems able to act.

This time I tried to be strong, and I did start to act — I started to separate our accounts and find a new place — but I’m not sure that I’ll be able to do it completely. Her sadness touches me, and I don’t want to hurt her. Should I leave or should I give us another chance?

Sincerely,

Unable to Decide

Gadfly.jl — The Pure Julia Plotting Library From Your Dreams
By: Emmett Boudreau
Tags: Analytics, Data Visualization, Data, Programming, Data Science

Introduction

If you have been working with Julia for even a short amount of time, you might be familiar with a plotting library called Plots.jl. Plots.jl is a simple library that provides ports to Python libraries such as Plot.ly and Matplotlib with simple functional methods like plot() and scatter(). While this is certainly a great way to get around creating an entirely new library for use in the Julia programming language, it also presents a few problems.

Firstly and most importantly, interpreting Python with Julia creates a lot of problems with performance. From just simply importing Plots.jl to actually plotting values, the performance with Plots.jl is absolutely abysmal! On top of not being Julian, a lot of the software is missing in the Julia version, and many features are entirely overlooked. While GR is likely the most promising back-end for Plots.jl, it lacks a lot of the great features that might be available for you with Pythonic libraries. Despite this, I do have an article you could check out to improve your GR visualization skills with Plots.jl:

So with these serious fundamental flaws with Plots.jl, it is easy to see why scientists have looked elsewhere for great statistical visualization in the Julia language. One of the best options I have looked at is a statistical graphing library called

Gadfly.jl.

First and foremost, it should be noted that Gadfly is very similar to another library for which I am the creator, called Hone.jl. The two both use the same back-end, Compose.jl, for drawing vector graphics in Julia. The similarities might not end there, but there are also a lot of key differences between them, such as Hone’s object-oriented and modular methodology which is not at all in line with Gadfly’s. Despite this, Gadfly does take a very interesting methodology in its own right, and works pretty differently than other plotting libraries that you might draw some similarities to.

Sleepless midnight poems (Session 44)

"If I told you

I am hurting,

would you stop

or would

you

dig deeper?

Sometimes I

wonder when

I'm laying

and my eyes

are fixed

to the ceiling

I wish it were

starry.

And I try

to hold to that

thinking, you know?

So my will would not

mistaken me,

and stay.

But you seem

to be a mind reader,

because your fingertips

find the trail from

my mouth

to my doom.

To sanity and hatred.

And I give in

and I almost can

remember what

was I thinking.

And your touch

I can't tell.

Hardly soft,

or just

softly hard.

Either way

it hurts so good.

And as I open

my mouth,

I remember

what was I

thinking;

I'm an open book,

but you don't know

how to read."
Alpine Life

Today it only rained once. From the morning until the evening it rained in one go. I actually do think it started raining at midnight and never stopped since. That was also what they predicted in the weather forecast.

With those predictions, we decided not to go for a long hike high up in the mountains. With all the snow melting and being washed away that would be too dangerous is this type of weather.

Instead, we choose to visit a famous gorge in this area which you couldn’t visit on a sunny day due to too many visitors. Since it is such a popular spot even during corona times it is crowded. A few people had the same idea as us today but that didn’t bother us.

Arriving at the bottom of the gorge we could see the river coming down with a lot of water due to all the rain during the past few days. The noise was overwhelming and only got more intense the further we hiked into the gorge.

Despite the rain, I did enjoy this excursion. The gorge was located in a thick mountain forest that was shining through the rain in grandiose colors. An amazing spectacle to be witnessed here.

Saint in Brown and White

I watch her from my bench on

Kreshatyk Street. The cup of tea

warms my hands and soothes my throat.

There is something beatific

in this face: a babushka

in brown and white. The sun conducted

by her eyes, its warmth spread down

to hands holding empty cup

which fills with translucent light.

A hurried woman dressed in black

stops transfixed by her smile.

A hundred hryvnia joins the light.

The ancient hand holds to restrain

a moment more to face the sky.

Released with prayer, black leaves brown

with a surer, lighter step.

I have seen the beggars on the streets

but not this time and not today.

On Kreshatyk sipping tea

from an empty cup, I wait

wistfully for the light:

a blessing clothed in brown and white.
Diversity and inclusion at Pinterest

Tracy Chou | Pinterest software engineer

Last October, I posed the question: “Where are the numbers?”. It was a call to action for the tech industry to share metrics on diversity in the workplace. Without measurement and transparency, it’s impossible to have honest conversations about making tech more inclusive. Since then, more than 150 startups have shared their women in engineering numbers, and some of the largest and most prominent tech companies have published their stats.

Today we’re taking our latest step by giving a more holistic look at our demographics across the company. We’re not close to where we want to be, but we’re working on it.

Our vision is to help people live inspired lives — people across the world, from all walks of life. We only stand to improve the quality and impact of our products if the people building them are representative of the user base and reflect the same diversity of demography, culture, life experiences and interests that makes our community so vibrant.

As we look ahead, we’ve put particular focus on inclusion efforts in hiring earlier in the engineering pipeline, recruiting a 29% female inaugural engineering intern class last year and 32% female this year. Beyond hiring, we’re mindful of processes and practices that may affect success and retention of employees coming from less represented backgrounds.

We’re also working with organizations that are effecting real change, including:

Collaborating with Girls Who Code, CODE2040, Girls Teaching Girls to Code, Anita Borg Institute, Hackbright Academy, and Out for Undergrad

Working with the creators of the documentary CODE: Debugging the Gender Gap

Hosting local events around Change the Ratio and Grace Hopper

While we’ve made some progress in diversifying gender at the company, we haven’t done as well in representing different ethnicities, and we’re focused on getting better. We still have a lot of work ahead of us to make Pinterest a global company, as we build a global product. However, we’re excited to be a part of a broader movement in the tech industry to make it a more diverse and inclusive place.

*Gender and ethnicity data are global and include hires starting through September 2014. This is not based on EEO-1 reports; however, ethnicity refers to the EEO-1 categories which we know are imperfect categorizations of race and ethnicity, but reflect the U.S. government reporting requirements.

**Other includes Biracial, American Indian, Alaskan Native, Native Hawaiian and Pacific Islander.

***Tech includes Engineering, Product Management, and Design. Business includes all disciplines outside of Tech.

I am broken, inside and out

From the inside out

From my head to my toes

From my childhood to now

Breaking things a

Super power all my own

But I am learning to heal

Learning to fit the

Pieces back together

Like a puzzle without edges

Learning boundaries

Learning to be free

Scars all over from what

Life has me put me through

From what I have done

What has been done to me

The way the world is

Has changed… so have I

Scars cover hurt places

Making them stronger

Helping those places

Hold together against

The breaks, the storms

All that life throws at me

I have learned to love

My broken places

Learned to love

The way I hold it together

Learned to recognize

When to step back

When things are

Breaking again

I can hold on

Call for help

Learn to move

Through the pain

Learning every day

How to live a broken life

At the same time

Accepting the breaks

Accepting help

Accepting myself

By: Luxor Tech
Tags: Cryptocurrency Investment, Cryptocurrency, Bitcoin Mining, Setup Guide, Bitcoin

Just received your DragonMint B52 Sia miner? Don’t stress we are here to help you set it up!

To get started, navigate to your dashboard by finding your miners’ IP address using your router or DragonMint IP scanner. The page will look something like this:

You should see the option to mine with a number of different pools. We’re going to set it up with Luxor’s Sia Prime Mining Pool, the best mining pool — disclaimer: we’re slightly biased :)

To check out more about Luxor Mining click here.

Okay, that’s enough promoting for one day… lets continue setting up your DragonMint B52!

Pick one of the above Stratum nodes (ensure it is port 3335), and type in the pool setting as follows:

URL: stratum+tcp://scp-us.luxor.tech:3335 (set to your nearest location)

Worker: LuxorUsername.workername (Workername can be anything, but avoid using symbols or special characters as it may be an invalid username)

Password: 123

For the other nodes (Pool 2 and Pool 3), feel free to use any of the other region nodes, such as scp-eu.luxor.tech:3335.

Once you’ve started hashing, grab yourself a beer! It’ll take about 5 minutes for your worker to appear on our stats page. To find your user, simply go to mining.luxor.tech/sia and type in your wallet address at the top of the searchbar. You should see something like this:

Happy Hashing!

In this blog, we are going to learn RxJava(RxJava2) operators by examples.

I personally believe that we can solve any complex problem very easily with RxJava Operators which can be very difficult without RxJava. RxJava is just awesome.

Don’t forget: There is an operator for everything in RxJava.

The best way to learn RxJava(RxJava) operators is to learn them by examples. In this blog, I have composed a few great problems with solutions using the RxJava operators. Let’s learn by one by one.

I recommend learning one example a day. So don’t forget to bookmark this blog post to refer on the next day.

Nowadays, most of the applications that we use in our daily life come with a search feature which provides us a facility to get things very quickly we are looking for. So, having a search feature is very important. And, we as a developer have a responsibility to implement it in a better way.

The solution uses the following operators:

Filter Operator

Debounce Operator

Operator DistinctUntilChanged Operator

Operator SwitchMap Operator

We will learn all the above four RxJava Operators.

Learn from here.

Zip operator allows us to get the results from multiple observables at a time.

This operator helps you to run all the tasks in parallel and returns the results of all the tasks in a single callback when all the tasks are completed.

Learn from here.

Caching is very useful in the following situations:

Reduce network calls: We can reduce the network calls by caching the network response.

We can reduce the network calls by caching the network response. Fetch the data very fast: We can fetch the data very fast if it is cached.

Let’s learn how to implement caching in Android using the following RxJava Operators:

Concat Operator

FirstElement Operator

Don’t Be Ashamed About Depression
By: Jake O'Callaghan

Depression isn’t your fault

It’s been said a million times, but I’ll say it again — depression is an illness, not a moral failing. People that are depressed are typically just as strong as nondepressed people. In fact, depression often makes people stronger than the average person. Dealing with an illness on a regular basis tends to make you tough and resilient.

Though the stigma is improving, many still view depression as weakness or something to be ashamed of. This is due to the misconception that one can “will themselves out of depression”, which simply isn’t true. You didn’t get depressed by choice, and you can’t fix it by forcing yourself to be happy.

Don’t get me wrong, I don’t advocate giving in to defeat and self-pity. You still have an opportunity to make the best of your situation and figure out solutions to your predicament.

But, if you’re like many depressed people, you force yourself to function, to do positive things like exercise, and try to cultivate a positive mindset. In other words, you do the things that make most people happy, yet you still feel overwhelming sadness.

So, don’t get down on yourself. Sure, you’re not perfect — you have days when you let the disease win — but who is? You’re doing the best you can with what you’ve been given.

So, try not to be so hard on yourself. The truth is, you’re fighting harder than most to live a great life; you just have an illness holding you back. You may not get the results you deserve for your efforts, but, at the end of the day, you should be proud of yourself for pushing through adversity.

As I’m sure you know, depression is complicated. Getting to the root of the problem is difficult, and everyone is different. I definitely can’t say why you’re depressed or what you should do, but I can comfortably say that you shouldn’t be ashamed — not for a second. You deal with a difficult condition on a regular basis.

You’re no mental midget. You’re damn strong. Don’t forget it.
