Conflict, Memory, and Pleasure
By: Mediocre Mind
Tags: Conflict, Memory, Pleasure

Conflict rises due to comparison. To compare, we need two things: the mind provides an immense tool to create two things: memory. To compare what we want to be and what we are, to compare what we’ve done and what we should do.

Memory is the cascading of experiences and thoughts in the stitching of time. Both the time stitching backward and time stitching forward which is a mere memory about the future — goals, expectations, imagination, and so on; this linearity in our mind sophisticates the stage to compare and therefore raises a conflict in our mind.

Hence, we are destined to conflict between things even when they are right, and we tend to compare it with the future, that this normality won’t have anything to do with the latter. All this because of the notion of time — the chain of cause and effect.

Pleasure is a loop in time when we need a repetition of the pleasured experiences again and again. It is the escape from the mundane linearity which causes expectations, conflict, and fear — other terms for comparison.

It breaks the linearity, sometimes the notion of time itself, therefore breaking the conflict in beliefs, ideas, thoughts, it grabs the whole attention of the experiencer, implying providing the eternality of time, the present.

That is what one wants, an escape from the causal chain when there is only present, and there is nothing else to compare with the now.

That’s why one seeks pleasure more often when the comparison is unstoppable; he wants time cessation.
What’s new in Elyra 2.0
By: Patrick Titzler
Tags: IBM, Jupyter Notebook, Data Science, Jupyterlab, Open Source

Earlier this month JupyterLab 3.0 was released, providing a slew of new features. In this blog post I’ll recap a few highlights and how the Elyra 2.0 extensions take advantage of them.

Support for Language Servers

Many modern integrated development environments simplify development by providing editor features like autocomplete, “go to definition”, “find references”, or linting.

JupyterLab optionally supports these features by integrating with Language Servers using the jupyterlab-lsp extension. Language Servers are available for many languages, such as Python and R.

Some Language Servers might not support every convenience feature.

Elyra 2.0 includes the Python Language Server, enabling these features in the notebook editor and Python script editor, as shown below.

Lint code, use auto-complete, open signature preview, find references and more using the Python Language Server integration

You can add support for other languages by installing the appropriate Language Server and its prerequisites.

Visual debugger

JupyterLab includes a visual debugger front-end that supports common debugging tasks. For example, you can set breakpoints, step through code, or inspect data. The front-end requires a kernel with support for debugging.

As of January 2021 the only Jupyter Python kernel that supports debugging is xeus-python .

Do note that this kernel currently does not support all iPython features, such as cell magics.

Neither JupyterLab 3.0 nor Elyra 2.0 install xeus-python by default. You therefore have to install it separately from PyPI, conda, or build from source code.

Debugging a notebook

To debug a notebook, associate it with a debugger enabled kernel and enable the debugger. The official debugger example Python notebook provides a short introduction and is highly recommended!

Classification — Machine Learning with Python
By: Gautam Siwach
Tags: Lighhouse, Machine Learning, IBM, Nvidia

Classification is a supervised learning approach in machine learning, For Example — It is a process of categorizing or “classifying” objects into “classes.” We can determine the relationship between a set of feature variables and a target variable of importance. The target is a categorical variable with discrete values.

In K-Nearest Neighbors

A very high value of K (ex. K = 100) produces an overly generalized model, while a very low value of k (ex. k = 1) produces a highly complex model.

A classifier with lower log loss has better accuracy.

Accuracy is the count of predictions where your predicted value equals the actual value. Accuracy is not always a good indicator because of its yes or no nature. Log Loss takes into account the uncertainty of your prediction based on how much it varies from the actual label. A lower log-loss value means better predictions.

When building a decision tree, we want to split the nodes in a way that decreases entropy and increases information gain.

Classification with decision tree, Constructing a decision tree is all about finding attribute that returns the highest information gain. The information gain is based on the decrease in entropy after a data set is split on an attribute.
IBM’s new 2nm chip
By: Amador Palacios
Tags: IBM, Chips

A little over a month ago, IBM announced that it had taken a very important step in chip design, developing a 2nm chip.

For those who do not know, chip manufacturing technology is measured in “nm” nano-meters (one billionth of a meter), which is the size of a transistor inside the chip. And the smaller the size of the transistors, the more they fit on the silicon wafer, giving the chip more computing power and at the same time consuming less power.

In the case of these new 2nm chips, their power consumption is reduced by a quarter and their computing power is increased by 45%. In other words, if it is placed on a mobile phone, it would last us operating 4 times longer than the current ones. Which is an important advance.

The chips being manufactured today are in the 10 and 7 nm scale, and there are already announcements from TSMC to start manufacturing 5 nm chips within 2 years.

The new chips announced by IBM could begin to manufacture within 4 years, and since IBM does not manufacture chips, it sells the license of its technology to other companies that are dedicated to manufacturing them.

For years it has been announced that the physical limit in the manufacture of silicon chips is being reached, but a way is still being found to reduce its size and improve its performance. We still have silicon chips for more than a decade.

Which is not to say that there are others looking for alternatives for the future, and those alternatives are in gallium arsenide (GaAs) and in carbon nanotubes that were also introduced by IBM more than 20 years ago.

These are alternative technologies that are not yet known when they will hit the market.

At the moment the chip market is very lively as these components are used in all kinds of products, and all large companies try to have their own designs to differentiate themselves and not depend on others, but in the end they all depend on the chip manufacturers that they are very few and are almost all in Asia (Korea, Taiwan and China).

The recent lack of chip supply has been a wake-up call for Western governments and large companies to be aware of the mistake they have made by trusting most of their manufacturing to distant countries. What is cheap today can be very expensive tomorrow.

And the most expensive thing is when you don’t have what you need.

IBM has its clear ideas and maintains the technology of chip design, even if it does not manufacture them. And it has the most advanced technology in the world and is a vital technology for everyone.

IBM’s people are not stupid at all.
MicroK8s on S390x!
By: K. Tsakalozos
Tags: Linux, Ubuntu, IBM, Kubernetes, DevOps

s390x or IBM Z is one of those exotic (at least to me) architectures brought to us by the genius people over at IBM.

Feast your eye to those gorgeous IBM mainframes you will never get to own in your home lab :)

IBM Z mainframes are those monster machines that are not for you. Don’t feel bad, they even exceed the needs of small companies. So you might ask “what does MicroK8s have to do with such not-so-micro machines”? Well, MicroK8s is growing production grade features, s390x is one of them. Also, it is dead simple to support a new architecture on a snap! Let’s see how.

Why s390x was easy to support?

MicroK8s code lives on github (“like and subscribe” as a normal youtuber would say) and is mirrored in launchpad. That is where the magic happens! In launchpad you can ask launchpad builders to build your snap and push it to a channel/track. For MikroK8s we have one such builder for each Kubernetes version from v1.22 all the way to v1.10. Here is how the 1.22 snap builder is configured so it automatically assembles the MicroK8s snap parts and puts them in the 1.22/edge channel:

The microk8s-1.22 snap builder recipe.

The most exciting part comes when you click the edit button on this snap builder:

All the architectures just one click away.

Yes, you got it right. These are all the architectures you can build a snap for; just by ticking a checkbox! Your snap can support the usual, x86–64 and ARM but also IBM’s s390x, and PowerPC. I cannot wait to get my hands on a RISC-V build.

Weekend project!

Do not waste any more time. Put your software in a snap and sail to the “Great Sea of Opportunity”.

Enjoy!

How To Write a Strong Headline for Your Offer
By: Nick Chai
Tags: Audience, Headlines, Marketing Strategies, Marketing, Copywriting

4. Summarise Your Offer With a Headline

Once you’ve gathered info on your audience’s interest and created a compelling hook, it’s time to write your headline.

And it’ll come naturally since you’ve done the hard work of researching every bit of information you can find. If it’s not easy for you to write, that means your research isn’t enough to appeal to your audience.

Keep in mind that your headline has one job only — to capture your audience’s attention. It should appeal to your audience’s pain through their interest.

It should stop them from scrolling past your offer and make them click to find out more.

A rule of thumb is that you should never try to sell with your headline.

Clickbait happens whenever marketers try to do that. Clickbait may bring clicks and traffic to your offer, but it’ll hurt your business in the long run.

So a clear, strong headline should only consist of the audience’s interest and nothing else. This is crucial when writing a headline to prevent clickbait. Let me give you an example.

Interest: SEMRush, Seth Godin, Gary Vaynerchuck (Content Marketing)

Problem: Marketing their business

Wants: Leads

My objective: To offer a marketing solution through content creation

Tonality: Professional

Headlines:

a. *Your offer name* is the only content marketing solution you need

b. Here’s how *your offer name* can help you generate consistent traffic and leads to your site.

c. Find out how our clients used *your offer name* to generate consistent monthly traffic and leads

d. *Your offer name* will help you achieve content marketing success by curating your content accordingly to generate consistent leads.

e. Many successful businesses trust *your offer name* for its effectiveness in driving consistent traffic and leads in their content marketing.

These are some headlines for example purposes. They mainly pique your interest and curiosity to persuade you to click if you’re interested in this niche.

Notice that I don’t use any fear-based headlines because these headlines drive a negative impression of being salesy on your offer.

Fear-based headlines to avoid:

a. Your marketing is having trouble because you’re missing out on *your offer name* for your content marketing

b. Never worry about marketing again once you use *your offer name* for your content marketing

c. You’re leaving money on the table! *Your offer name*will help you solve that

d. Not enough traffic and leads? *Your offer name* will save the day

e. Forget spending money on ads. *Your offer name* will generate 3x more consistent traffic and leads to your site for free

Some marketers out there will teach you to use fear-based marketing because it’s stronger.

But if you don’t know how to use it, I would recommend staying away from it. Poorly executed fear-based marketing can backfire and affect your business. Just stick to your customer’s interest.

Certified Organic Skin Care
By: Fatima Zahra Ach
Tags: Health Care Reform, Headlines, Organic Healthy Food, Organic, Health

Certified organic skin care is one of the beauty industry’s rapidly growing areas. It is likely that through the use of an array skin care and body products, typical women apply over two-hundred chemicals to their skin daily. Moreover, recent studies have shown that sixty percent of the chemicals are absorbed by the bloodstream. It has also been established that numerous people with eczema, skin complaints, and allergies have been provoked by chemicals in body and skin care products.

A lot of products for skin care are known or suspected to contain neutroxins, hormone disruptors, and carcinogens. Man-made fragrances, as well as those natural fragrances are often allergenic. Ingredients such as sheep’s wool may be polluted with pesticides. Other chemicals in these products interrelate with nitrites that form carcinogens known as nitrosamines.

The best means of steering clear of these artificial chemicals to enter the body is the use of only certified organic skin care products, which are chemical-free and fresh. So what are certified organic skin careproducts? These are products with organic components which have been grown without using artificial pesticides and fertilizers. The nagval regulations that govern organically grown produce, also forbid the utilization of ingredients that are genetically modified.

Products that claim to be organically grown must hold at least ninety-five percent of organically grown make. While a product that claims to be certified organic skin care product must be prepared with organic components containing seventy-percent of organically grown ingredients.

A lot of products for skin care, both from the mainstream companies and the natural, hold either triethanolamine (TEA) or diethanolamine (DEA), which may sometimes cause chemical reaction. Two foremost causes for irritation and allergy in products for skin care are preservatives and fragrances, which may sometimes cause reddened skin, irritation, watery eyes, or allergic reactions, as well as other reactions including restlessness, mood changes, memory lapses, nausea, depression, irritability, lethargy, and incapacity to concentrate.

Conventional skin care products frena need bactericides and preservatives to protect them from contamination, and most of these components release irritating and allergenic reactions. They can never do away with using these ingredients as they serve as one of the main components of the product. Certified organic skincare products offer a great alternative for skin care with much more benefits: both on the outside gently yet effectively caring for the skin, and the inside not being intoxicated with chemicals.

World-Renowned Doctor Saves This Dying Grandma’s Life By Uncovering The 10 Second Ancient “Fat Hack” That Removes Up To 11 Pounds Of Deadly-Visceral-Fat Every 7 Days… tony jackson Apr 25·3 min read

Pray for me Shaun!”

she shouted at me hysterically.

“The doctor just told me it’s

surrounding my heart and organs…

And I only have a 12% chance of surviving!”

I’ll never forget the day I received that devastating phone call and my whole world came crashing down.

I thought her life was over.

And although it’s extremely painful and difficult for me to relive this nightmare…

Thankfully it was all part of God’s plan…

Because my wife’s near-death experience sent me on a quest.

An unexpected journey that would save her life by uncovering the “missing piece” of the weight loss puzzle for hundreds of thousands of people in their 40s, 50s, and 60s…

A secret, that has been hidden underground and unheard-of until now.

And you’ll be even more excited to know it doesn’t require you to change your diet, or exercise more.

Yet it instantly goes to work by stopping the storage of fat cells.

After months of frustration, failure, and disappointment of trying every diet and regimen under the sun, my bride and best friend in the world Karen, a 60-year old grandma from Michigan, used it to lose eleven pounds of stuck belly fat in the first week alone.

Losing over 30 pounds of life-threatening visceral fat directly from her lower belly region, hips, arms and backside.

Restoring her energy levels and mental clarity back to the days of her youth…

… soothing all her aches and pains… revitalizing her sex drive…

Giving her the schoolgirl complexion she thought she would never get back.

Skyrocketing her confidence and self-esteem to entirely new levels…

Leaving her friends, family and doctors shocked and in-awe, dying to know how she did it all so fast.

An astounding breakthrough, backed by clinical research, that is so effective. So powerful.

It finally exposes and eliminates

the #1 hidden culprit of your

troublesome belly fat, accelerated

aging, and slow metabolism.

And it has absolutely nothing to do with your hormones, or the metabolism your mom and dad gave you.

This remarkably easy over-40 protocol, that takes as little as 10 seconds each day has been an anti-aging and longevity secret of the Asian culture for decades…

… but it was originally discovered in Egypt centuries ago.

How To Create A Magnetic Headline And Drive Traffic To Your Content

How To Create A Magnetic Headline And Drive Traffic To Your Content Godswill Igiakong Sep 6·3 min read

Have you heard of the book called Astro-logical Love?

I guess you haven't. The book was written by Naura Hayden in 1982.

She printed it out and struggled to sell up to 2000 copies in her first print run.

She had to sell the remaining books to discount book stores.

While at a discount book store, a Publisher picked it up and scanned through it. He discovered that this was a good book with a bad title(headline).

He called Naura Hayden and bought the rights to the book.

He republished this book without changing a single word in the book. The only thing he changed was the title.

What did he change it to?

How to Satisfy a Woman Every Time… and Have Her Beg for More!

Now just imagine you’re in a bookshop searching for a book to buy around that subject

And you see "Astro-logical love" and "How to Satisfy a Woman…". Which would you buy?

After just this change in the title of the book, over 2 million copies of the book were sold in the first eighteen months.

That’s the power of a magnetic headline!

There's this saying "You have only one chance to make a good first impression"

As a content creator or writer, your headline is your first impression.

Statistics have shown that 8 out of every 10 people read the headline but only 2 people go further to read the content.

If you want to increase the number of people consuming your content, then you need to come up with a Magnetic headline

A headline that would draw people in to go further and consume your content.

How do you write such a headline?

1. Your headline must have a Big Promise

Show them what's in it for them if they go ahead to click on your post or read more.

2. Increase the Curiosity factor in your headline

Human beings are very curious. Once you can pique their curiosity, you've gotten to them.

Start with "How" and leave out the "to"

Example: How I increased my Instagram followers from 10 to 1000 in one week.

This would make almost everybody want to know how you managed to do this.

3. Double the Benefits

Your headline should focus on showing your audience what's in it for them- Benefits.

Now imagine doubling the benefits in your headline. Giving them two benefits. You're showing them they can't completely lose out. They must get something.

Dale Carnegie used this in his book, How to Win Friends and Influence People.

Double benefits! This works like a magnet. It grabs the attention of your audience and sucks them into your content.

In a highly competitive market like the online market where everyone is competing for attention, your headline can be all you need to stand out from the crowd.

Don't sleep on it!

Stay Liquid,

Titles, Dave, titles.
By: Denise Shelton
Tags: Politics, Headlines

Titles, Dave, titles. That’s the biggest difference I can see. The story that did well has a title that inspires curiosity. It’s not obviously left-leaning at all. If I were a right-winger, I’d see that title and think, “At last! We’re getting some traction on Medium. I want to read this.” The left-winger looks at it and thinks, “What? That’s alarming! I’d better check this out.”

Run all the those titles through Coschedule’s Headline Analyzer and see what you scores you get.

Two other things I’ve learned is that people are more likely to respond to something that prompts a strong emotional reaction and they generally like to know what to expect from an article. Unless they’ve heard of Dave Volek, they’re not interested in why he should be president. They recognize that this is probably humor, but it’s not clear whether or not the concept is going to be funny enough to be worth their time.

So, yeah, people like to fight, especially now when everyone is so freaked out, but that’s not why your one story did so much better than the others. Nobody’s going to read your stuff if they can’t get past the title and the other titles weren’t interesting enough.

If you’re a big shot with 100,000 followers, your fans will read your grocery list. Those of us further down the food chain have to try a lot harder.
Vitamins or Medicines? A Simple Copywriting Approach

Vitamins or Medicines? A Simple Copywriting Approach

Picture bought by the author on Depositphotos

If you are struggling with the right words to sell, think of yourself as a doctor, your leads as patients, your product as the treatment, and your copy as a medical consultation.

Even if you are not operating in the trillion-dollar pharma industry, there is power in this simplicity.

The cure approach

Medicines bring salvation when the harm is already done.

Your leads are in pain. They bloody well know where their pain points are situated. As a copywriter, it’s your task to show that you are aware of the discomfort and stress.

Here are a few examples of how you can start your sales headline.

Are you sick of…

Do you feel bad when…

Your trained eye noticed that these are simple yes/no questions. That’s not an accident. Questions have a strong side effect.

Have another look at the subtitle of this article:

Are you tired of slow growth?

If this triggered you into reading this article, that’s kind of strange. After all, you answered the question with a yes or no. And yet, you are here because our brain is wired to follow the path of curiosity.

Questions grab attention. In the overload information era, that’s a big win. It’s not a sale, but you are getting a huge step closer.

Let’s have a look at the vitamin approach.

The boost approach

Vitamins boost your system. They build up resistance and give you energy.

Your solution does the same. It can give your customers

a head start

advantage over competitors

a motivation kick to perform better

Here are some simple examples of how you can use this in your headline copy:

Boost your …

Do you want to revive your… ?

Gain more…

Fill in the dots with whatever magic your product or service offers.

As with most simple stuff, this works wonderfully well.

Now what?

Your sales headline can either open or close the door to your remarkable remedy.

In that respect, the above is only a starting point. If the rest of your copy stinks, your headline won’t make a difference.

On the other hand, the beginning is the hardest part. Once you get that right, the rest of your copy can come easier.

Two more things before you take off to kill the pain of your customers:

You can apply this everywhere: your marketing emails, ads, landing page, call to action in your blog posts… You can mix medicines and vitamins. The combination of treatments can result in healthier sales figures.

Hope this helps you somehow. Thanks for your time.
Factory Method Design Pattern
By: Anton Smirnov
Tags: Design Patterns, Java, Factory Pattern, Automation Testing, Automation

Factory Method is a creational design pattern that provides an interface for creating objects in a superclass but allows subclasses to alter the type of objects that will be created.

In software engineering, creational design patterns are design patterns that deal with object creation mechanisms, trying to create objects in a manner suitable to the situation. The basic form of object creation could result in design problems or added complexity to the design. Creational design patterns solve this problem by somehow controlling this object creation.

Abstract Factory

Creates an instance of several families of classes

Creates an instance of several families of classes Builder

Separates object construction from its representation

Separates object construction from its representation Factory Method

Creates an instance of several derived classes

Creates an instance of several derived classes Object Pool

Avoid expensive acquisition and release of resources by recycling objects that are no longer in use

Avoid expensive acquisition and release of resources by recycling objects that are no longer in use Prototype

A fully initialized instance to be copied or cloned

A fully initialized instance to be copied or cloned Singleton

A class of which only a single instance can exist

The factory design pattern says that define an interface ( A java interface or an abstract class) and let the subclasses decide which object to instantiate. The factory method in the interface lets a class defers the instantiation to one or more concrete subclasses. Since these design patterns talk about the instantiation of an object and so it comes under the category of creational design pattern. If we notice the name Factory method, that means there is a method which is a factory, and in general, factories are involved with creational stuff and here with this, an object is being created. It is one of the best ways to create an object where object creation logic is hidden from the client. Now Let’s look at the implementation.
Connecting Oracle database in Cypress project
By: Poopae Paisingkhon
Tags: Automation Testing, Oracle, Cypress, Testing

Last month, I’ve learned about how to connect oracle DB with NodeJS for my cypress project. Actually, I got stuck in some problems when I tried to connect at first. In the article, I present to you how to connect to Oracle databases in the cypress project, and how to solve the problems I’ve found. Hope this will be useful for someone who has the same issue as I had.

Pre-requisite

NodeJs

Cypress project

Oracle Instant Client

Typescript (optional)

Installing node-oracle package

First of all, we have to install oracledb in our project using the below command.

npm install oracledb — save-dev

Adding configuration

We can define the database configurations and node version in cypress.json file.

By default, Cypress uses the node from its bundle version, but I want to load oracleDB with my system’s Node version (My cypress’s version is 6.8.0. It uses bundled Node.js version 12.18.3, but my local Node.js version is 10.24.0) so I set the value system to my nodeVersion. If I do not set it, I got the below error:

Error: NJS-045: cannot load a node-oracledb binary for Node.js 12.18.3 (darwin x64)

For database configuration, we can set all properties such as username, password, and connection string in cypress.json file to make it easier for updating the value in the future.

remark: you can verify the bundled Node version using npx cypress version command

Creating task plugin Event to query data

In this step, we are going to create a task to both connect to the database and query the data. Go to ../plugin/index.js file

Create event name sqlQuery . Inside, it returns the value from the query method: queryData method with query parameter and config.env.db parameter

Specify Oracle client library path in your local machine at initOracleClient([Object options]); . I also got the below timed out when I forgot to specify this line.

create query method to return the query value with await operator.

use connection.execute() to execute sql statement

Creating the Testcase

We can call the event using cy.task and pass the sql script to query the data from oracle database.

and then try run the script to verify the result.

You also can verify the log in the browser console.

the result in the browser console

For my example project, you can clone it from the Link

In this article, we are talking about Incoming Webhooks with AWS Lambda. How we can send the slack message from AWS Lambda using Incoming Webhooks.

What is the incoming Webhook?

Incoming Webhooks are a simple way to post messages from apps into Slack. Creating an Incoming Webhook gives you a unique URL to which you send a JSON payload with the message text and some options. You can use all the usual formatting and layout blocks with Incoming Webhooks to make the messages stand out.

Let's move on Slack and start our exercise.

Install Incoming WebHooks plugin into your slack.

Goto App Directory > Search `Incoming WebHooks`.

Click on `Incoming WebHooks`, It will display like belove

Click on `Add to Slack`.

Configure Incoming WebHooks in the specific slack channel.

Add Slack Channel name to get notification

Copy Webhook URL

Enter the Description of your WebHook.

Enter the Name of your WebHook If you want any customize name default it will be ` incoming-webhook `.

`. If you want any custom icon to add that in Customize Icon section.

Click on Save Setting.

Once you setup Incoming WebHooks into any slack channel it will send notification like belove.

Now we successfully add our Incoming WebHooks plugin in the slack channel 🎊 🎉🤖🎊 🎉

Now let's move on AWS console

In the Lambda console, choose to Create function. Choose Author from scratch. Under Basic information, add the following: For Function name, enter a name that identifies it as the function used to Stop your EC2 instances. For example, “StartEC2Instances”. For Runtime, choose Python 3.7 or Node.js 12.x . Under Permissions, expand Choose or create an execution role. Under the Execution role, choose to use an existing role. Under the Existing role, choose the IAM role that you created. Choose to Create a function. Copy this code, and then under Function code, paste it into the editor panel in the code editor (lambda_function).

If you select Python as a runtime environment, you can use this code.

If you select Node.js as a runtime environment, You can use this code.

Tags: Ruby, Web Testing, Selenium, Automation Testing, Cucumber

Hi bro, meet again with me, yesterday i’m explore automation web testing with ruby language. And Finally I’m successful to run automation with scenario : Check Result Advanced Search when Search about Elon Musk. This time I will share the results of my explore about automation with ruby.

Here are the steps :

1. Install Ruby, you can follow this link for installation : https://www.digitalocean.com/community/tutorials/how-to-install-ruby-on-rails-with-rbenv-on-ubuntu-18-04

2. Download Chromedriver and Geckodriver, you can follow link in below :

a. chromedriver : https://chromedriver.chromium.org/

b. geckodriver : https://github.com/mozilla/geckodriver/releases

Then extract files (chromedriver dan geckodriver) and move file in to directory with path usr/bin , which is placement ruby installed.

With this steps :

a. open folder geckodriver/chromedriver with terminal

b. used this command for move file : sudo mv chromedriver /usr/bin/

*repeat b step for move geckodriver

Next, make this driver (chromedriver dan geckodriver) executable with this command : sudo chmod +x /usr/bin/chromedriver

*repeat command for executable geckodriver

*notes : for user mac , you can type command in below for installation webdriver (chromedriver) : brew cask install chromedriver

3. Install selenium (for connecting to webdriver like a chromedriver/geckodriver), cucumber(for gherkin languages / BDD), and rspec (for expect/assert from testscript) with this command :

a. gem install selenium-webdriver

b. gem install cucumber

c. gem install rspec

Type this command : cucumber --init , for generate features folder, inside there are 2 folder (steps_definitions and support)

4. Create files inside features folder with name advancedSearch.feature and then copy code in below :

5. Create files inside folder step_definitons with name stepsAdvancedSearch.rb and then copy code in below :

6. Run test-script with this command : “cucumber”

And then, this result like a below :

7. For generate report, you can use this command :

“ cucumber -f html -o report.html ”

And then, for open report, you can use this command ,

“ google-chrome report.html ”, this report like a below :

*notes : you can see full code in my repo : https://github.com/setyokun/learn-ruby-x-cucumber

Organize your visuals with folders on Picter
Tags: SaaS, Content, Marketing, Workflow, Features

You’re all familiar with folders. They’re everywhere. And perhaps you don’t put much thought into it, but having a good folder structure can seriously improve your productivity.

Imagine the following situation.

You’re on your computer, putting the finishing touches on the visuals of an advertising campaign when ding! a Slack message comes in from your manager: “Where are the visuals we used for the LA Auto Show two years ago? You and Stacy worked on it, I think? We’re pitching a car manufacturer and need it as reference.”

For most of us, this leads to countless wasted hours searching through old projects and files trying to remember file names and locations.

But all this wasted time can be avoided. How? By using Folders on Picter to organise visuals and folder structures.

Folders on Picter are a way for you to better organise your work by grouping related projects together into one folder. In this post we’ll show you a few examples of how to structure your folders in your workspace.
Google Cloud Composer (built on Apache Airflow) Simplified

Google Cloud Platform gives a service called Cloud Composer to schedule, and monitor pipelines that span across hybrid and multi-cloud environments, this service is built on the Apache Airflow open source project and operated using python. When I started using this service, I was not sure how to implement it and use it for my project purpose, I did lot of research and investigation to know more on this service and with time my knowledge on this service has evolved.

Google Cloud Composer built on Apache Airflow

This article is mostly for beginners to understand very basics of Cloud Composer and those who wants to use Cloud Composer for orchestration their data pipelines built in GCP, so lets gets started.

Lets assume that the Airflow environment is already created for your GCP project. Type composer in GCP search bar, which opens a UI as shown below:

Composer UI

Lets understand some important options:

Name: is your project name in which the composer environment was created, this will be attached to your project. If you want to create scheduling across projects then you need a project connection to be established (https://cloud.google.com/composer/docs/how-to/managing/connections)

Airflow: This will open up the airflow scheduling UI, where you can see the workflow, trigger a workflow (DAG), check the logs, etc.

DAGs: Directed Acyclic Graph is a collection of all the tasks you want to run, organized in a way that reflects their relationships and dependencies. A DAG is defined in a Python script, which represents the DAGs structure (tasks and their dependencies) as code. We will see a sample DAG in the below section.
Artificial Intelligence driven Workflows

Since a couple of years, Artificial Intelligence has entered every nook and corner of the IT Industry. How many of you understand the term Artificial Intelligence? I am sure in pure English it is pretty easy to understand, but when Technology meet English what happens??

What is Artificial Intelligence (AI)?

AI is a multidisciplinary science, but advances in machine learning and in-depth learning to create paradigm shifts in almost every field of technology.

Why are AI services required?

Enterprise users are placed with power of fully trained machine learning models. AI bridges the gap between data scientists and business users, making it easy for the organizations to leverage critical information to AI services.

Can workflows be driven by Artificial Intelligence?

Yes, of course! AI and Workflows are converging in the most valuable ways to drive better outcome. Let’s consider a way in which information get ingested and subsequently consumed during a business process. Many process are initiated by the customer or owner — lets consider an example of an insurance claim for underwriting. The primary thing we have to verify is the claim form entered correctly, with all the required information and signatures. Then the application has to be processed, extracted, and verified the required details both from the insurance company and the customer to initiate underwriting process. During the process, the claim is put on hold waiting for documents to be received from the hospital. Again, once the medical documents are received, the workflow can proceed and, ultimately the claim can be issued.

This is the worth that AI brings to workflows, ingesting critical information leading to proper deciding.

If we envision deep-learning driven processes, they can automate decision making process intelligently. Let’s assume there are conditions derived for workflows to run, can it not comply with dynamic business conditions? Yes, it can. It only takes the business owner to change the business conditions in the workflows and it is all up and running. As an easy example, if based on the applicants income “x%” of the loan is approved today, due to market conditions business owner wants to change “x% to y%” can be done without the help of the IT team and the change in the workflow is running within a couple of hours. Workflow processes are easy to manage dynamic changes and helps reduce the cost to a greater extend.

Conclusion

AI driven workflows should be more than just a useful new addition to your enterprise; it should be at the forefront of your organization’s informational operations. We can train an ML model fast and at scale to deliver results that are nearly instantaneous and as accurate as a human.

Disconnects between your IT and Business teams of your business no longer jeopardize progress toward organizational goals; instead, they are being bridged with intelligent, enterprise AI services.

The goal of better workflows begin AI and ML.
