Let says you are working on a project and you have dependencies of code from some another repository, which you need in your project code.

  • One way is to copy the code from another repository manually to yours whenever it gets update not so good way :sad:
  • Another way is to use git version control system to do that for you and it's super easy to do :smile:

Let me show you how we can do it.

Fetching from Another Repository

git add remote other <repository_link>
git fetch other
git checkout <your_target_branch>
git checkout -p other/target-branch file_path

If you have multiple files you have to just change the last checkout statement to

git checkout other/target-branch file_path1 file_path2

But wait there is one catch here that is the path of the file in your repository should be a mirror image (same as) of the path of the file in another repository you are fetching from.

Fetching from Same Repository

Now If you want to fetch files from another branch of the same repository you have to just do

git checkout other_branch_name file_path1 file_path2

I have to admit that it has been three years now working with git, but it still excites me that there is a lot of things that I do not know about git, If you also have some important time-saving git commands which you feel can save someone else time to share in comment because sharing is caring :sunglasses: .

Cheers!

Happy Coding

Identity & Access Management let the user manage access control/policies to the resources by defining who(identity) and what they can access(roles). Today we will talk about the Google Cloud Identity & Access Management and understand what it is and How to use it.

Policy in IAM is composed of the binding list which binds the Member Identity and Roles together to limit the access on google cloud resources.

Member can be of the following type

  • Google Account: This can be any valid Google account with gmail.com or with any other domain name.
  • Service Account: Account related to the application rather than an individual, you can have as many numbers of service account for the logical components of your application.
  • Google Group: Google group are the collection of the different Google account and service account. Every group has a unique email id which can be used to identify members in the IAM policy. The benefit of group account is that if you want to change the permission of user you can simply move the user from one group to another group rather than changing the permission of the users.
  • G Suited domain: Is the virtual group of all the account created in the organization Suite.

Roles on other hand is collection of permission which is mainly represented as .., for example pubsub.subscriptions.consume. Permission determines what type of operation can be performed on resources. Permission cannot be directly applied to resources instead you can assign roles which are a group of different permission.

In Google Cloud Platform Roles are of three kinds

  • Primitive Roles
  • Predefined Roles
  • Custom Roles

Primitive Roles

These are of three types Owner, Editor and Viewer as the name suggest.

  • Viewer has only access to view the resources and data.
  • Editor has Viewer permission + permission to change/edit the resources.
  • Owner has the permission of editor + permission to manage all resources and user.

Predefined Roles

These are the roles provides by Cloud IAM in addition to primitive roles which provide more granular level access to the resources and these primitive roles differ based on different resources in the cloud, you can check these roles over here

Custom Roles

Cloud IAM let the user define different custom roles if primitive and predefined roles do not fulfill their requirements. Though there is some pointer to remember while creating the custom roles. Custom roles can be defined on Organization and Project level but not on Folder level and custom roles should have an iam.roles.creator

So now the question is how these rules actually work as we know that policy is the binding list which binds the member and roles. These policies are connected to resources and are enforce access control when these resources are accessed.

Google Cloud Policy have a hierarchy Organization > Folder > Project > Resources, every resource has exactly one parent and inherit the policy from its parent. Any policy assign on the parent is applied to all its child's. Here is the diagram from Google Cloud IAM docs which show how this hierarchy looks.


Here an example from official docs how permission hierarchy works,

In the diagram above, topic_a is a Cloud Pub/Sub resource that lives under the project example-prod. If you grant the Editor role to micah@gmail.com for example-prod, and grant the Publisher role to song@gmail.com for topic_a, you effectively grant the Editor role for topic_a to micah@gmail.com and the Publisher role to song@gmail.com.

So here my effort to explain Google IAM policy in simple words, Hope you find it usefully. Please do share any feedback or any topic you think I should cover in this post. Till then Happy Clouding :)

As part of my job, I have to scrape some website to help our sales team with data on the market, as of now they were doing it manually which is a bit of tedious job to do and consumes a lot of their productive time. So on bit searching and going through different tools and framework came across a framework named Scrapy. So here I am going to share how to set up and use Scrapy.

Scrapy is a free and open source web-crawling framework written in python which is used to extract data from a website without much of hassle. They have a very nice documentation you can check out here.

Steps to Install Scrapy

sudo apt-get install python-dev python-pip libxml2-dev libxslt1-dev zlib1g-dev libffi-dev libssl-dev pip install Scrapy

Steps to Create New Project

To create a Scrapy project type this command in your terminal.scrapy start project <project name>. Project structure will look like this

Now go ahead and create a python file at path /spiders and paste below code.

#!/usr/bin/env python3
import scrapy

class RedditSpider(scrapy.Spider):
    # name of the scrapper, it should be unique.
    name = "reddit"
    # list of the URL need to be iterated.
    start\_urls = \['https://www.reddit.com/'\]

    # Called to do any operation on the response of the above URL.
    def parse(self, response):
       # css selector of the anchor tag which contains the headers
       top\_post = response.css("a.SQnoC3ObvgnGjWt90zD9Z")
       for post in top\_post:
           self.log(post.css('::text').extract\_first())

To start scrapping, type

`scrapy crawl reddit`

Here we are scrapping the Reddit website for the latest post and getting the header of all the post. The output of the above code will look like this.

  • Trump Organization ‘Sold Property to Shell Company Linked to Maduro Regime,’ Says Report
  • Blind people of Reddit, what do you find sexually attractive?
  • A “caravan” of Americans is crossing the Canadian border to get affordable medical care
  • A “caravan” of Americans is crossing the Canadian border to get affordable medical care
  • [Post Game Thread] The Houston Rockets defeat the Golden State Warriors, 112-108, behind Harden's 38 points to level the series 2-2, despite the continued brilliance of Kevin Durant 18, my friend here is failing biology and thinks she's unroastable. Go for it guys, and go hard If you strike me down, I shall become more powerful than you can possibly imagine. [BOTW]
  • ELI5: Why are all economies expected to “grow”? Why is an equilibrium bad?
    ....

Now the best part of Scrapy is if you want to experiment around any website before creating any project you can easily do that.

scrapy shell 'https://www.reddit.com/'

And then can try a different CSS selector on the response. Though there is a lot more you can do with Scrapy like saving the result in JSON, CSV format and even integrate with Django project might show that in next post, till then goodbye.

Cheers

Generators is a function in which objects are created at once but not all code is executed at once as done in normal function. In normal function execution from top to the return statement. A function that consists of a yield statement is called a generator's function. The execution of the generator function happens differently, in which the code execution stops at the yield statement rather than a return statement, to move to the next statement next() method is called which will start the execution of the code from where it is left over. If no yield statement is found a StopIteration exception is raised.

So let's see how to create, execute a Generators in python.

def fib(n):
    a, b = 0, 1
    while a <= n:
        yield a   # yield statement.
        a, b = b, a + b

Now let execute the method fib().

fib_fun = fib(10)
next(fib_fun) # 0
next(fib_fun) # 1
next(fib_fun) # 1
.
.
.
next(fib_fun) # 8
next(fib_fun) # reached the end will raise StopIteration Error.
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
StopIteration

Else you can use for loop which call next() in the background.

for fib\_value in fib(10):
    print(fib)

# Output
0
1
1
2
3
5
8

So here we today understand the Generators concept in python. Now you would be thinking where we can use this, let me state some use cases.

  • Can be used for memory management, where we pass the whole list at once, we can use Generator to pass data one by one so that less load comes on memory.
  • Generator can be used to define infinite streams.

If you know any more use case, please do share in the comments and if want to share something else or talk about Generators feel free to ping me on twitter

Till then Cheers :)
Happy Digging.

Today we will talk about Closure a functional object in Python.

Closure is a function object which has access to the local variables/free variables of the enclosing scope and can be executed outside its scope. Nested function is a Closure function if

  • It can access variables that are local to enclosing scope.
  • It can be executed outside for its scope.

Closure can be used for one of these

  • Replacing the hard coded constants.
  • Eliminating global.
  • Can be used for data hiding and many other things.

So lets see with a code snippet to see how closure and nested function are different from each other.

# nested functions 
def inc_x(x):  
    def add_10(x=x):
        print("{0} is increased by 10 = {1}".format(x, x+10)) 
    return add_10()  # remember about the parenthesis.
  
inc_value = inc_x(10)
inc_value  #Output: 10 is increased by 10 = 20

So the above function will be called a Nested function, not a Closure because

  • Inner function [add10] doesn't access the local variable of enclosing function incx. It used the value of X rather than using a reference.
  • Inner function [add10] cannot be executed outside the scope of incx.

Now let see the Closure function example.

# closure functions 
def inc_x(x):  
    def add_10(): 
        print("{0} is increased by 10 = {1}".format(x, x+10)) 
    return add_10 # returning function without parenthesis, passing only references.

inc_value = inc_x(10)
# We are able to execute the inner function outside its scope.
inc_value() 
#Output: 10 is increased by 10 = 20

So above code will be called as Closure function rather than Nested function because

  • add10 function is accessing the local variable of the incx function. Here a reference to the local variable of incx is maintained in the add10.
  • add10 can even be executed outside the body/scope of incx function.

Closure in python is created by a function call, here every time incx is called a new instance of this function is created. So whenever you call incx a binding reference is made to x which is used in add_10 function.

So let see how under the hood these variable reference are maintained

  • Function attributes func_closure in python < 3.X or closure in python > 3. X save the these references to these variable or also called as free variable. Let see how to access these values.
# Taking same example for the above code
def inc_x(x):  
    def add_10(): 
        print("{0} is increased by 10 = {1}".format(x, x+10)) 
    return add_10

add_10 = inc_x(30)

add_10()
# Output: 30 is increased by 10 = 40

# Checking whether it is Closure or not.

'__closure__'  in  dir(add\_10)

# Output: True

# Getting the free variable value from closure.

add_10.__closure__[0].cell_contents 

# Output: 30

While talking about the closure we also heard the term free variables which is also an interesting topic to discuss, which I will cover in the next blog post, till then

Cheers !! :)

Today I am very much excited to share with you my first song video on the Dgplug platform via YouTube 'Zara Zara'.

Do you know what gives more satisfaction in life? Is it academics or getting an engineering degree? ;D Mostly it is Nurturing your skills and finding a platform to present yourself.

For me publishing my song gives me more satisfaction. In the end, when the time will come to retire it will not be the CGPAs but the risky path in chasing your passion and the crazy things we did with friends that will keep us smiling :)

Yesterday on 1st October was the Foundation Day of The Scriptink. I always imagined how easy it seems to maintain the project made apart from the idea of any normal college projects. The audience always sees only the result and not the path. Coming to the point, Me being in Scriptink I came to know how hard is it to keep maintaining the consistency. U may be wondering, consistency in what way.

Definitely, You would be following our Scriptink through the app, youtube LinkedIn page. More than 2 years of consistency in posting the monthly short videos is a great achievement in itself. This is what the audience sees. But inside a team is working day and night to make this 2 min short video possible.

Not much to say, but Scriptink is all about us and not about I.

Click on this to experience the 2 years journey with us

It was one of the best decisions to invest some time with DGPLUG summer training 2019 as I partially owe them my job.

During my virtual on-campus interview, I mentioned what I did during my summer vacation and bonus skills like blogging, helped me land an offer in a multinational company with a networking role.

I was asked what are my hobbies. Mostly everyone begins to answer like I love to sing and so on... I began explaining to them about my blogging and to prove them I briefly shared the story about Edward Snowden and the Internet's Own Boy, Aaron Swartz, which gave me an edge over other participants.

Once again, Thanks DGPLUG :)

Would love to connect with you.

Every year JPMorgan Chase & Co. conducts Code for Good Hackathon at a large scale to hire fresh graduates from the engineering college which every student keeps an eye on...

Luckily, I was one of the shortlisted candidates for the current Code for Good Hackathon 2020. This article is for my friends who are waiting for some insights on their upcoming CFG Hackathon.


Welcome

Welcome


Key Points:

  • The first day was mainly for jelling up with teammates. You need to express what you are good at and decide among teammates to come up on the same page.
  • The ** second-day**, I liked it the most. That was a workshop on technical skills like a web page and Git usage. Also, it's better if you have early knowledge of git and you should at least have an idea on how to solve the merge conflict.
  • NOW, the third day, THE D-Day, Basically the main Hackathon where you will Brainstorm + Code will be of only 24 hours.

Try to focus on developing the main requirement posed by the non-profit NGO's. Keep on updating about your work to your teammates and mentors so that they can help you if you get stuck on it for more time.


Schedule

Schedule for 3 days Hackathon


Skills to focus:

  • Communicate effectively with teammates and mentors. As we all the sailors with a common goal to reach the surface.
  • Knowledge of HTML, CSS, Bootstrap + any app-related knowledge is plus.
  • Knowledge of SQL and XAMP server.
  • Basic knowledge of git push, git pull, git merge, and ability to solve the merge conflict. It is advisable to try collaborating on a dummy file with your friend before entering into the hackathon.

Our Presentation on The Nudge Foundation: Click here for Presentation and Demo

Conclusion

Hackathon is not only for hacking into problems but also knowing new faces, sharing stories, and building memories.

The End is the new beginning

Last weekend I attended EuroPython sprints that were virtually conducted. The communication platform for the conference was discord and was kept the same for the sprints too. It served a good platform as we were able to pair program with the maintainer by sharing our screens.

Day 1

Sprints opened at 12:30 PM IST and started with its first round of project introduction. A total of 12 projects that took part in this year's sprint. Though the project maintainers were from varied timezone and timezones are difficult to handle. The first opening of sprints only had a few maintainers of the project to talk about their project.

The project that I started off in the day one of the sprints was terminusdb. I primarily contributed to terminudb's python client which had Cheuk Ting Ho and Kevin Chekov Feeney to help us out. Kevin had coded the JS Client of the project and was here to work on the Python Client.

The issue I picked up was increasing the test coverage of the project and while working on that issue I also discovered some other issues. Some depreciated function was still being used in the client and the make file did not have a command to generate coverage HTML of the project.

By the end of day one, I had moved the coverage of terminusdb_client/woqlclient/connectionConfig.py to 70% from 62% with a PR to remove the deprecated function from the client. Doing that I learned about graph databases and how terminusdb has git like features for the database.

Day 2

I started late on the second day and continued to work on the test coverage PR. I fixed some minor flake8 errors in my test coverage PR and pushed to coverage to 75% and created a PR for that make file command. A lot of people in sprints were confused in setup of project. So opened up a documentation issue for writing the wiki for setup instructions and contributions guidelines for new/first time contributors.

Just an hour before the first closing session I moved to scanapi which is maintained by Camila Maia. I picked up some good first issues and got them merged in no time. I saw this project at the closing of the day-1 and found it very interesting.

The other projects that I really found interesting but could not contribute to were Hypothesis, strawberry GraphQL and commitizen.

Overall I had a really fun weekend and I am excited to contribute more to those projects.

I recently stumbled across a very peculiar topic called Bit Manipulation. In most of my programming days, I haven't actually relied on the binary operation to get me the result, I know under the hood everything is converted into 0's and 1's but it was all abstraction to me.

The case was different here. While working with Bit Manipulation, I had to actually rely on arithmetic bit operations to get me to the result. So it became real interesting real soon.

Bitwise operators

Basic operation done on bits are done with bitwise operators. Since we primarily work on bits these operations are fast and are optimized to reduce time complexity.

The first three &, | and ~ are fairly straightforward. So I would briefly go over it.

&: if both bits are of equal size than & operator would compare each position and would return True/1 if input bits are True/1. Similarly for False/0.

    6       : 1 1 0
    5       : 1 0 1
            -------- &
              1 0 0

|: if both bits are of equal size than & operator would compare each position and would return True/1 if input bits differ. Similarly for False/0.

     5       : 1 0 0
     3       : 0 1 1
            --------  |
              1 1 1

~: Not operator just compliments the bit it gets. In fancy computer lingo it gives one’s complement of a number.

    5       : 1 0 1
            -------- ~
              0 1 0

Now coming to more interesting operators:

Operator Name
^ XOR
>> Right Shift
<< Left Shift
XOR

If two bits are of two equal-size ^ of both bits in the compared position would be 1 if compared bits are of different binary and would be 0 if bot the compared bits are the same.

    6       : 1 1 0
    5       : 1 0 1
            -------- ^
              0 1 1
  • XOR of a number with itself is 0

    x = "Any int number"
    (x ^ x) == 0
    
  • XOR of a number with 0 is number itself.

    (x ^ 0) == 0
    
  • Ordering in XOR does not matter, both will give the same output.

    output = (7 ^ 3) ^ (5 ^ 4 ^ 5) ^ (3 ^ 4)
    output = 7 ^ (3 ^ (5 ^ 4 ^ 5)) ^ (3 ^ 4)
    

While discussing Left Shift,<< and Right Shift, >> we will be talking about arithmetic shifts.

Left shift <<

  • Left shift shifts the binary digits by n, pads 0’s on the right.
  • Left shift is equivalent to multiplying the bit pattern with 2 power k( if we are shifting k bits )
1 << 1 = 2 = 1 * (2  ** 1) 
1 << 2 = 4 = 1 *(2  ** 2) 
1 << 3 = 8 = 1 * (2  ** 3)
1 << 4 = 16 = 1* (2  ** 4)
…
1 << n = 2n

Right shift >>

  • Shifts the binary digits by n, pads 0's on the left.
  • Right shift is equivalent to dividing the bit pattern with 2k ( if we are shifting k bits ).
4 >> 1 = 2
6 >> 1 = 3
5 >> 1 = 2
16 >> 4 = 1

Both Right shift and Left shift operators come real handy in masking.

Masking allows the user to check/change a particular bit at a particular position.

Some of the common functions associated with masking are:

Set Bit
  • The set bit method is generally used to SET a particular with 1.
  • To achieve this we would need to create a mask at the particular position where we want to SET
  • The mask can be created with the help of the << if the left shift operator.
def set_bit(x, position):
    mask = 1 << position
    return x | mask

set_bit(6,1)
  • In the above code snippet we are SETing the bit at 0th index.
    masking = 1 << 0 = 1 * (2 ** 0) 
    
    6       : 1 1 0
    1 << 0  : 0 0 1
            -------- |
              1 1 1
IS BIT SET
def is_bit_set(x, position):
    shifted = x >> position
    return shifted & 1
Clearing Bit
def clear_bit(x, position):
    mask = 1 << position
    return x & ~mask
Flip Bit
def flip_bit(x, position):
    mask = 1 << position
    return x ^ mask
Modify Bit
def modify_bit(x, position, state):
    """
    state is param that tells us to set a bit 
    or clear a bit
    """
    mask = 1 << position
    return (x & ~mask) | (-state & mask)

Observations

Bit manipulation can be used to solve problems that you are familiar with but necessarily don't know about. Here are some of my observations that I noted while using bit manipulation.

To check if the number is even
  • & ANDing the number with 1 gives 0 or 1 — 0 if it's even — 1 if it's odd
x = "Any int number here"
(x & 1) == 0

Practice Question

To check if the number is a power of two
  • If a number is x binary representation of (x-1) can be obtained by simply flipping all the bits to the right of rightmost 1 in x and also including the rightmost 1.
Let, x = 4 = (100)2
x - 1 = 3 = (011)2
Let, x = 6 = (110)2
x - 1 = 5 = (101)2
  • x & (x-1) will have all the bits equal to the x except for the rightmost 1 in x. In the given example below the values enclosed in || are the same for both the x and x-1 if x is not the power of 2.
  • If the number is neither zero nor a power of two, it will have 1 in more than one place.
Let, x = 6 = 1|1|0
(x- 1) = 5 = 1|0|1

Let,x = 16 = |1|0000
(x-1) = 15 = |0|1111

Let,x = 8 = |1|000
(x-1) = 7 = |0|111

Let,x = 23 = 1011|1|
(x-1) = 22 = 1011|0|
x = "Any int number here"
(x & x-1) == 0

There are a lot more things that can be done with just bits and are definitely not limited to the above observations. Try to find your own observations. Happy coding!

I recently finished reading Python Testing with Pytest by Brian Okken and I am glad I picked this up rather than jumping into the docs. It's definitely a good introduction for people who haven't had their share of testing a python codebase, let alone be with Pytest.

The book introduces a python CLI called Tasks and takes this as a base for writing all of its tests throughout the course of the book. Though eventually, the tests become more complex when you get into the latter half of the book.

The pros of the book are that it covers almost every section of the framework from fixtures, plugins, custom pytest configuration and even using pytest with tools like coverage and mock. But if you're someone like me who hasn't had his share of testing a python codebase you might find yourself with a bit of information overload at times.

I did find the book a bit of overwhelming on chapters like writing your own plugin, custom configuration and using pytest with Jenkins because these are the features that I wouldn't be using right out of the box. I would definitely be coming back to these chapters in the future if I need any of the features.

Overall the book is really well-written keeping in mind beginners who are just picking up pytest as their first testing framework and also for folks who are moving towards pytest from any other testing framework. Exercises at the back of every chapter make sure you also get some hands-on experience of writing tests.

Just a personal tip for anyone who is picking this up and has less experience with pytest. Feel free to skip chapters or skim chapters that aren't useful right out of the box. You can always come back to them when you need those features.

2019 has been a year of new beginnings both personally and professionally. This was the year I got my first job, the first salary and on the contrary to that, I did give my first resignation. Yeah, that was fun!

This blog just highlights most of the things I did in the previous year.

Blog Posts

I did post out 8 blogs this year. I know it's not that much. Initially, I had planned one blog a month. But by the end of the year during the time I was giving interviews for the new job things started to fall and I could not commit to one blog a month.

The plan for this year is to blog more or at least be consistent with writing. Stick to at least one blog per month.

Books

The previous year was a good reading year compared to the last few years. The Kindle I bought came real handy during the long metro rides. Plus I got some tech books cheap compared to their paperback prices so I did finish some of them too.

This year I started to take up reading non-tech books a bit more seriously. So I am picking up a book a month and finishing it slowly. Keeping in consideration that the book is less than 800-1000 pages for the initial months just to help in making a momentum.

Recently finished Parliamental and will be moving to The Elephant Vanishes.

Talks

I did give one talk at PyConf Hyderabad 2019 one of my favorite regional conferences in India. I also did submit one for a PyDelhi meetup but sadly by the time, it was scheduled I had already relocated. More on that later.

Open Source Contributions

One of the major things that I want to work towards this year is towards making more upstream contributions.

Last year I did submit two document patches to one org aio-libs . The project was aiopg, async version of Postgres but that happened by sheer luck. As I was going through the documentation I found some of the documentation to be using old-styled decorator based coroutines instead of new async def function. So I submitted a patch to update them.

Free Software

“Free” software “is software that can be used, studied, and modified,” copied, changed with little or no restriction, and which can be copied and redistributed in modified or unmodified form. Free software is available gratis (free of charge) in most cases. “In practice, for software to be distributed as free software, the human-readable form of the program (the source code) must be made available” along “ with a notice granting the” user permission to further adapt the code and continue its redistribution for free. This notice either grants a “free software license”, or releases the source code into the public domain.

Open-Source Software

In the beginning, all software was free in the 1960s, when IBM and others sold the first large-scale computers, these machines came with software which was free. This software could be freely shared among users, The software came written in a programming language (source code available), and it could be improved and modified. Manufacturers were happy that people were writing software that made their machines useful. Then proprietary software dominated the software landscape as manufacturers removed access to the source code. IBM and others realized that most users couldn’t or didn’t want to “fix” their own software and There was money to be made in leasing or licensing software. By the mid-1970s almost all software was proprietary “Proprietary software is software that is owned by an individual or a company (usually the one that developed it). There are almost always major restrictions on its use, and its source code is almost always kept secret.” users were not allowed to redistribute it, source code is not available users cannot modify the programs. Software is an additional product that was for sale In 1980 US copyright law was modified to include software In late 1970s and early 1980s, two different groups started what became known as the open-source software movement: East coast, Richard Stallman (1985), formerly a programmer at the MIT AI Lab, launched the GNU Project and the Free Software Foundation. “to satisfy the need for and give the benefit of ‘software freedom’ to computer users ultimate goal of the GNU Project was to build a free operating system the GNU General Public License (GPL) was designed to ensure that the software produced by GNU will remain free, and to promote the production of more and more free software.

GroupPhoto Give respect to what you love and you will find the way to get it out to the world. Today I want to share with you my journey conducting WRITOFEST 2k19.

  • Establishment of app : We had a very solid idea but an uneven path on how we will implement this idea which was to make a platform for the readers. Our idea was unique as there were no such platforms where through the app users can get a quality quote and Shayari as the market was operating on the users' content.

  • Came up with daily writing contest idea As it was obvious that we had to face low user engagement in the beginning so we came up with the idea of “Daily Writing Contest” which gives the users a chance of getting featured on the wall of the Scriptink app under the title “Best writing of the day”. Fortunately, it worked, writings started coming. It was at this time we came in touch with various writers whose writings could become a part of the Scriptink Family.

  • Getting recognized as college group. There was a lot of confusion about whether opening a college group will distract us from our objective but in the end, we formed it intending to build a team that will continuously work for improving the product.

  • Came up with Writing competition. After being recognized as a college group first we need to conduct an event to establish our existence in the college. The “WRITOFEST 2K19” was our first National level Literary Fest.

  • Came up with the idea of including Poets Scriptink started walking on the path less traveled by. Including the events featuring famous poets was one of our masterpieces. But the path was not as easy as always. Contacting distinguished poets like Javed Akthar, Chetan Bhagat was full of fun and was like getting goosebumps every second with the excitement that we had talked with these celebrities.

  • Digital marketing Our digital marketing was damn too good. We somehow managed to get it posted on the INSTA and FB pages of Jai Ojha sir who had followers nationally. It was like WOW moments for us.

  • Sponsorship Some part of our event was college-sponsored but our budget requirement was much more. So we needed sponsorships. At some places, we got disappointment where they were ready to give support but later it didn't correspond with our college terms.

  • Conducted the event successfully The 10-day rigorous reach-out campaign resulted in having Jai Ojha sir(Poet), Alok Puranik (Satirist), Parameshwaran PS(Ted Speaker) as our chief guest. And the event went smoothly the better than we expected.

Our team spirit made impossible things possible. To which we will always pat ourselves.

PyCon India is one of those conferences that I look forward to every year. This year marked my fourth conference in a row. I was excited to meet all my old friends and make some new ones.

ChennaiPy the local python user group of Chennai hosted this year's conference. This meant two things I will get to attend the conference in Chennai and also visit some beaches around Pondicherry. So yeah I was super excited.

The journey to the conference started on 11 October, I was traveling from Delhi with two of my friends Kuntal and Sakshi. Since we planned our journey in such a way that we would reach one night before the conference, we missed the pre-conference volunteer's meet. Kuntal and I were in a state of regret of not taking the morning flight as the pre-conference volunteer's meet are super fun. You get to see the venue beforehand, helps out with swag bags and interact with all the volunteers and organizers of the conference.

On reaching the Chennai airport we met with Dedipyaman, he was staying with us. His name was a bit unique so we called him twodee, which he later adopted as his nick. Traveling to our Airbnb apartment was a challenge in itself as none of us knew Tamil. We were staying with 13 other folks, I knew most of them besides one, Shubo. I had seen the nick on the #dgplug but haven't met him in person. When we arrived at the apartment only Shubo was present, rest came in an hour or two. As everyone settled, we played some rounds of Uno while enjoying pizzas just before going to bed.

The next day I left with twodee and Sakshi for the conference, we were running a bit late. When we reached the conference I saw Kuntal at the registration desk. We all got our attendee card and proceeded to the conference. I saw all my old friends, most of them I only personally meet during conferences as they all live in a different state. So it was fun to catch up. After roaming around the sponsors both I went to attend Pradyun's talk. The talk was titled Python Packaging – where we are and where we're headed, I was interested in the talk as only a handful of people maintain pip. Since it's such a huge ecosystem in itself it was interesting to get some insights from Pradyun's talk about how packaging works with pip and how are they planning to move forward. Later in the tea break, I met with Saurav and Haris. I learned a lot from the conversion we had during the tea break. These people have been in tech much before me. Saurav talked about his company Deepsource, how managing a small team with people who take up responsibility is easy. You don't have to worry about those formal things like timesheets, leave policy because people take responsibility for their work. Haris was working in a two-person team and shockingly carried a very old cell phone which didn't even have internet. So his take on life was very interesting.

The next day we had our annual #dgplug staircase meeting, this year since Kushal was sick. Sayan took the initiative of conducting the meeting. We discussed the first staircase meeting, what went wrong in this year's summer training that people weren't completing their tasks, weren't showing up in the IRC channel and what needs to be done now. I meet lambainsaan who I had always thought was a bot.

The meeting concluded at noon and it was just in time for me to catch up the talk “Let's hunt a memory leak” so I ran to the hall to get a good spot. Sanket was the speaker, he showed us various ways how he solved memory leak problems in a flask app in production while describing the whole memory management concept in Python. I rushed for lunch after the talk as I had to be in open spaces for the PyDelhi's session.

Anuvrat had registred the open space for PyDelhi and other communities of the north. The whole agenda of the open space was how to be consistent while conducting the meetup, what can we do in the meetup we get people to come often and how can we increase the quality of the talks. I liked one idea of pushing all the 101 sessions to blog posts or even hangout sessions a day before the event so we aren't limiting the target audience to just people who are starting in tech. Of what we have been observing in the recent meetups, experienced people who can help mentor people and give great talks have stopped attending meetups. The problem is there were a lot of 101 sessions happening. We concluded that we can shift those 101 sessions to blog posts and if someone wants to give a 101 session we can have themed meetups once in one-two months where they can present those talks. The open spaces were scheduled for half an hour but we stretched it a bit longer as more people started adding points to the discussion.

Before the closing keynote of the day I helped in volunteering at hall-B, I was so much excited for the keynote that during the tea break before the closing keynote I went and sat in the second row of the hall just so I can enjoy the talk from a good spot.

The conference ended with David Beazley keynote, he live coded a stack machine, wrote an interpreter for Web Assembly game that was initially written for Rust in Python and in the end added PyGame to make it into an actual game. It was a jaw-dropping moment for me, though I lost in the midway of his talk it was a bit advanced for me. But when I looked around most people were feeling the same. The keynote ended with standing ovation from all the people in the hall. For me, the whole closing keynote was like a movie it was such a joy to just watch David live code and nothing could have been a better way to end a conference.

The last day of our stay in Chennai was a bit weird as there was some issue with water in our apartment so we went a bit late to the workshop. I had bought tickets for David's workshop “Write your own Async”. In the workshop I tried to follow up with him, was writing code just as he would do it but after the second half, I was a bit lost so I just focused on listening to him. It was not exactly like a workshop but more of him giving us a problem and we would discuss the solution to it and he would live code the solution after the discussion. The solutions were so well designed that it would be similar to the inbuilt functions that the Async module has. As I tried to live coded with him so wasn't able to make some detailed notes that I could revisit later.But luckily he uploaded the workshop screencast so I can revise the concepts again.

The day ended with me saying goodbye to all the people that had stayed late during the dev sprints as workshop and devsprints were happening in parallel.

This marked the end to one more year of my PyCon India journey. It was my fourth PyCon India and the most special one. I stayed with people that I look up to in real life and had lots of fun. The funny thing is not all of them use Python as their day to day language yet they came to a conference dedicated towards the language. I guess that's the beauty of the community. You meet so many people from different backgrounds and learn from them which not only helps you be a better developer but also gives a different perspective towards your life.
