When working with data it's very useful to be able to create data pipelines where we can have tasks in a pipeline run in sequence or in parallel or have dependencies witch each other, where the next tasks will only run when their dependencies or previous tasks have finished running.

To accomplish, usually we'd use external task orchestrators like [Airflow](https://airflow.apache.org/), [Prefect](https://www.prefect.io/), [Nifi](https://nifi.apache.org/), or [Oozie](https://oozie.apache.org/).

In the version of Databricks as of this writing, by default we are unable to create jobs with multiple tasks as shown here:

![Single Task Job](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/5m3wf87lerfuuo8u6gnu.png)

But there's a way to add multiple tasks to a job in Databricks, and that's by enabling **Task Orchestration**. At the time of this writing, Task Orchestration is a feature that's in *public preview*. This means that it's currently available for everyone, but it's not enabled by default.

To enable it we first go to the the **Admin Console**:

![Admin Console](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/xjsubrc57mf32hstkins.png)

Then go to **Workspace Settings** tab:

![Workspace Settings](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/8y1rtwppdy6jn1dvouc8.png)

Then we'll search `Task` on the search bar. We'll then be able to see the switch for Task Orchestration:

![Enable Task Orchestration](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/djwlx5nhn7lu9069zy4x.png)

It might take some time to take effect but once that's enabled, we will now be able to see a button for adding another task to our job:

![Add Job Button](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/dadp96oddur216588t3a.png)

After that we can just add a task similar to what we're used to. The only difference is now there is a `Depends on` field where we can specify the dependencies of our current task:

![Depends On](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/qonbrf09zp3skn0pe70c.png)

Once we're done adding that, we can run our job and see something like this when it's complete!

![Complete Run](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/7bx9k2pxpq4644rqmrde.png)

And that's a wrap! I hope this helps you setup your own data pipeline in Databricks!

New GitHub Issues – first impressions
Tags: github, discuss, productivity, management
Published: 2021-10-15 13:02:39

GitHub is working on a new version of their project managing application, which will be tightly coupled with whole GitHub flow by itself. The project is currently in limited public beta – you can [sign up here](https://github.com/features/issues) and wait for the access.

## First impressions

I had the opportunity to use it for a while, and here are my quick first impressions:

1. It's kept in GitHub convention, with all pros and cons of its UX design.
2. You can create many views for each project, and switch between them smoothly.
3. All views can work in list or board layout, and you can switch them any time.
4. Creating a new item in the board layout is basically narrowed to its name. You can't and any extra fields, labels etc.
6. To add extra fields like iteration number, maybe some other option – you need to switch to list mode.
7. Every item can be converted to issue, you just need to choose one of your repositories.
8. Automation for every column was replaced with workflows. This new approach looks very promising, but for now, it offers only basic default workflows. You can turn them on and off, change their settings a little, but you cannot create your own. It's marked as "coming soon".
8. It's fast! One thing I truly hate in JIRA is its performance. GitHub Issues is fast as hell, but to be honest –  it looks poor even compared to old projects version.

## What is missing?

What should be added before taking it serious:

1. We must be able to edit items from each type of layout, not only from the board one.
2. It should be possible to add a description for the item draft.
3. There must be some kind of summary preview like in old version of GitHub projects.

## Should I use it?

Is it ready for business use? No, definitely not (it's still in beta stage, right?). There is a long way ahead of them, but I support the whole project strongly because it's time to break the dominance of JIRA in project managing software. So, keeping the fingers crossed!

Uygulamamız istemediğimiz halde hatalar olabilir. 

Bir olası durum : Diyelim ki bir uygulama yaptık, müşteriye teslim ettik. Uygulama takır takır çalışıyor. Bir sabah/gece telefon aldık müşteri telaşla anlatmaya başlıyor kullanıcılar şu işlemi yapamıyor, bu artık çalışmıyor vs.. Eğer hataları logladıysak diyebiliriz ki : Log'lara bakalım hallederiz. Eğer log'lamadıysak vay halimeze, kullanıcılardan nerede hata aldıklarını öğrenicez oraya debug'lar atacız, hatayı bulmaya çalışıcaz ve bulursak gidermeye çalışıcaz.. Böyle de yapılabilir tabi, log'lamadan hataları  bulabiliyorsak ama bu çok büyük bir zaman ve enerji kaybı, kaldıki o hataları bulabileceğimizin bir garantisi de yok, eğer zaten müşteri'yi memnun edemezsek gerekli zamanda/maliyette işlemi gerçekleştiremiyorsak bizler iyi birer yazılımcı değiliz demektir.

İşte iyi bir yazılımcı olmanın en önemli unusurlarından bir tanesi hataları log'lamaktır. 0 hata her zaman bir prensiptir ama hata olduğunda da onu bilmemiz gerekir.

Bu yazı serisinde : UseDeveloperExceptionPage, UseExceptionHandler göreceğiz aynı zamanda Serilog ile global hata yönetimi göreceğiz.

Bir dahaki yazımda aşağıdaki kodları açıklamak ile başlayacağım : 

```
public void Configure(IApplicationBuilder app, IWebHostEnvironment env)
{
    if (env.IsDevelopment())
    {
        app.UseDeveloperExceptionPage();
    }
    else
    {
        app.UseExceptionHandler("/Error");
    }
```

Bir dahaki yazımda görüşmek dileğiyle.

En iyi dileklerim ile.

Naming conventions for easy identification of StyledComponent and ReactComponent
Tags: discuss, react, javascript, programming
Published: 2021-10-15 12:27:40

## Do you have a good idea for a naming convention that makes it easy to distinguish between StyledComponent and ReactComponent?

I'm using StyledComponent in my current job.
In the source code, StyledComponent and ReactComponent have the same naming conventions, making it difficult to determine which type of component it is at a glance.

As my refactoring, I changed the naming as follows.

_Example_

**before**
```
return (
  <ScheduleContainer>
    <Header>
      <Date>
        Hello!
      </Date>
      <TypeSelectorContainer>
        <TypeSelector />
      </TypeSelectorContainer>
    </Header>
  </ScheduleContainer>
);

```

**after**
```
return (
  <Div_ScheduleContainer>
    <Header>   // <-React component
      <H2_Date>
        Hello!
      </H2_Date>
      <Div_TypeSelectorContainer>
        <TypeSelector />  // <-React component
      </Div_TypeSelectorContainer>
    </Header>  // <-React component
  </Div_ScheduleContainer>
);
```

However, this refactoring violates react/jsx-pascal-case in ESLint.

Do you have any better ideas than this?

Thanks for reading.
How to enable image preview in nnn with kitty terminal
Tags: bash, tips, howto, cli
Published: 2021-10-15 11:40:03

[NNN](https://github.com/jarun/nnn) is a very fast, minimal terminal-based file manager. You can easily navigate, manipulate files in the command line, and much more. If you're a terminal user, you should check this out. It'll supercharge your productivity to another level.



### Zsh/Bash/Fish config
You need to set a NNN_FIFO path and a key for the plugin with NNN_PLUG. I'm using "p" key to see the preview.

For zsh/bash users, copy this line into .bashrc or .zshrc

export NNN_FIFO="/tmp/nnn.fifo"
export NNN_PLUG="p:preview-tui"

For fish users, put this into config.fish file

set --export NNN_FIFO "/tmp/nnn.fifo"
set -x NNN_PLUG "p:preview-tui"


### Kitty config
 Open kitty config file ( ~/.config/kitty/kitty.conf ), find and change these variables:

 allow_remote_control yes
 listen_on unix:$TMPDIR/kitty
 enabled_layouts all

 That's it. Now, open nnn in a terminal and hover over an image file. Press 'p and see the preview of the image. You can change the split position by changing enabled_layout variable in kitty.conf
Learning Java after JavaScript
Tags: java, beginners, 100daysofcode, javascript
Published: 2021-10-15 12:03:30

## Enter
First tech post!

Some background: I took to learning web development after securing a spot at a coding fellowship in the end of 2020. It's been one heck of a journey since then.

I'm taking the reigns to learn Java. Why learn Java after JavaScript? Because I want to learn how to build and maintain mobile applications. So I'm happy to document this journey here. Some of my colleagues recommended Kotlin as the next stepping stone instead of Java, but I decided to learn that at a later time since foundational concepts of programming don't change.

## Java to JavaScript
**Stranger in a Strange World**

The Java ecosystem I've entered is very different from the comfy world of web development I normally work with in JavaScript. But I guess that's to be expected when learning a completely new language. Perhaps each major language has its own personality and niche, and it's cool to explore a brand new one.

So with learning Java:

- I've had my first brush of what it means to compile code and execute it after. Java compiles the source code into bytecode, which then the JVM (Java Virtual Machine) then executes the bytecode making it available to use on many devices.

- Java is strongly object oriented programming, because we can't develop a program without making use of classes.

- I learned there are a handful of primitive data types Java supports. They are: `byte`, `short`, `int`, `long`, `float`, `double`, `char`, `String`, `boolean`. Each varying in degree of the size they take up in memory.

- In Java, declaring a variable also means specifying what data type it is, which in JavaScript you don't have to. For instance, in Java if we declare `String message;`, initializing this variable with `message = 123` would be illegal because the value is an integer. But `message = "123";` would be legal since it's a string, correlating to its data type.

- Learned a little about packages in Java. Still a bit unsure about this topic, but from what I understood so far, importing packages are a way of utilizing various classes for specific procedures in your application. I'm thinking of it as a folder that holds many related files that could be useful. An example I used when coding was the Scanner package, which helps parse input from users on the terminal.

- In Java's arithmetic operations, division is a bit peculiar because dividing integers gives us whole numbers, even if there is a remainder. So the solution would be to use floating-point numbers. For instance: ![division in Java](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/chjn6mbv5ci9lf8un30s.png) 
 
There's also a handful of other small things I learned that I'll add if I remember them.

## Long Way to Go!

Still got a long way to go. But as of now, I'm enjoying the process! 😎

In the near future, I plan on doing some LeetCode problems with Java and learn about making an application on Android.

need a column starting 1 to 100:
```
    SELECT  LEVEL SL_NO
      FROM  DUAL
CONNECT BY  LEVEL <= 100;
```
what about dates, from a date to a date?
```
    SELECT  TO_DATE(:from_date, 'DD-MON-RRRR') + LEVEL - 1 SL_NO
      FROM  DUAL
CONNECT BY  LEVEL <= (TO_DATE(:to_date, 'DD-MON-RRRR') - TO_DATE(:from_date, 'DD-MON-RRRR'));
```
example use of date loop:
```
DECLARE
    l_FROM_DATE DATE;
    l_TO_DATE   DATE;
BEGIN
    l_FROM_DATE := TO_DATE('01/11/2021', 'DD/MM/RRRR');

Universities Should Prepare Programming Students for the Industry
Published: 2021-10-15 11:18:30

###Why most graduates can't get employed.###

There are so many students and graduates that are not in employment not because there is no employment but simply because students are not prepared for the industry. 

I have over four years experience in software development and I can testify that I have only applied not more than 10 percent of of what I learnt in university.

In the company I'm working for currently, I have been part of the panelists when interviewing individuals looking for employment and one thing I have realized is that Universities do not prepare students for the industry.

Applications or the kind of technology used in the real world keep changing rapidly while schools or university still teach the same technology that was taught years ago.

Basics should be taught but students should know what they will be dealing with in the real world, students should be exposed to real world solutions. 

Technology his growing so rapidly such that companies no longer use raw html and CSS to develop websites but frameworks that are fast and efficient. When you ask a fresh graduate from university, they apparently do not know what these frameworks are. Companies nowadays are looking for people that can get the work done real quick and not someone they will start teaching. These should be the technology students are familiar with even before they graduate. 

Mostly graduates are usually employed by startups and these startups want to generate income as fast as they can. So for them to achieve that, they are looking to employ competent people that can get the work done real fast.

I appeal to universities to take note of this so that they can help graduates get jobs as soon as they leave university or before.
10 Tips to Increase Domain & Page Authority
Tags: website, tips
Published: 2021-10-15 11:13:28

According to Moz, Domain Authority is a score that ranges from 0 to 100 that predicts how well a website will rank on search engines. If you have a high Domain Authority, it means that your website has a good chance of getting good rankings if it gets listed in Search Engine Result Pages (SERPs). Page Authority, on the other hand, is a score measuring the relative "authority" of any given web page and is used as part of Google's page ranking algorithm.

Here are 10 Steps to <a href="https://www.blogtriggers.com/2021/06/increase-da-and-pa-in-website.html">increase Domain and Page Authority</a>

1. Use link-building to increase your DA

2. Optimize your page titles and meta descriptions for search engines

3. Optimize your images for search results

4. Make sure your content is unique and relevant to your target audience

5. Update your site regularly, but make sure you don't overdo it!

6. Improve user experience with good design and straightforward navigation

7. Make sure you don't have broken links on your site (use the broken link checker tool)

8. Use social media for more inbound links to increase your DA and PA

9. Get links from other high-ranking sites(backlinko, neilpatel, search-engine-journal)

10. Try to do guest posts to improve your site's reputation and da pa score
