My first Sketchnotes on “The Sketchnote Handbook”

Ever since I got to know about “The Sketchnote Handbook“, I wanted to read it. The main reason of this curiosity is because there is a belief in me, which has been reflected in this book. The belief of communicating through the Visuals. What I mean with Visuals? It means global communication, which involves freedom to innovate, design, and being not restricted by any grammar, teacher, or a rule developed by so called over intellectuals. It is about communicating with anyone, and reflecting your understanding on the topic using icons, icons and random text.

English is a language not a measure of your intelligence

It did not take much time, may be a week, to read this book. As I relearned about how to give an importance of basic design techniques, in this book, I decided to keep a reflection of my understanding using sketch notes.

These two pictures speak about the my understanding with the topic that I studied through this book.

I hope you will use the same for your reference.

Please don’t think that you are not good at Drawing. If you need any motivation then please look at this picture of my daughter. Just like her, I am sure you were able to draw during your childhood.

Once again, it does not matter how bad or good you are in Sketching or English, your focus should be on just sketch sketch sketch and speak your knowledge.



Debug Postman

Recently, I came across a situation when I wanted to see the result of console.log written as a part of Postman script.

I could not see any outgoing call or console logs in a console of my chrome.

After a bit of research it is understood that there is a separate way of opening a console screen of a chrome app package.

To enable this feature you need to type chrome://flags/#debug-packed-apps in the URL bar in your Chrome browser window:

Once it is enabled, restart your chrome. Now you can right click on the Postman app, and inspect.

Tada! You can now view console logs and any network calls going out of the Postman.

Browsemate – Search made easy in your open tabs, bookmark and history

Have you ever been in any situation, when you wanted to search for open – tab within your chrome windows or you are facing problem in finding the website you had visited earlier! Then this plugin is the correct choice for you.

With the help of this plugin you can search for a link in your open tabs, saved bookmarks and even your browser history.

You can search by page title, or a URL/link.

How to use it?

We have provided you the Browsemate search in your browser address bar or you can use this feature through a popup window, by pressing an icon on your browse right top corner.

Address Bar:

Type “bm <search criteria>” in your address bar and it will make all the similar links visible.

Popup Windows:

Click on browsemate icon, presented next to your address bar, and then type your search criteria. You can even use arrow keys.



Build Android – Continuous Integration with Jenkins and Docker


This tutorial assumes that you have Jenkins in the docker. You can read about installing the same here.


Once the jenkins instance, named jenkins-master, is installed go to the root bash i.e. command prompt for your container.

e.g. docker exec -it --user root jenkins-master bash

From the bash command run the following:

> cd /opt

Know the sdk version and download:

> wget

unzip file:

> tar zxvf <filename of the just downloaded file>

You can now remove the file you just downloaded:

rm <filename of the just downloaded file>

Now some environment variables are required to be set.

vi /etc/profile.d/

By default the vim is not present in docker
you need to install by the following

apt-get update
apt-get install vim

Add the following lines:

export ANDROID_HOME="/opt/android-sdk-linux"
export PATH="$ANDROID_HOME/tools:$ANDROID_HOME/platform-tools:$PATH"

Then reload the file:

source /etc/profile

Now you should be able to call android from the command.


First list the available android sdk and platform tools:

android list sdk --all --extended

Get the item serial number from output and run:

> android update sdk -u -a -t <serial number>

Replace <serial number> for required: platform version,  android support library and sdk version.

Check your android gradle file for the required version.

For the Android SDK to be accessible by Jenkins, execute the following:

> chmod -R 755 /opt/android-sdk-linux

If you get this error
Cannot run program “/usr/local/android-sdk-linux/build-tools/19.0.3/aapt”: error=2, No such file or directory

then run this command: 

> apt-get install lib32stdc++6 lib32z1


All set and now reboot your container: 

docker restart CONTAINERNAME/ID

 If everything is done correctly, you should be able to set the gradle task and generate android apk/jar/aar :-).


Nodejs tools


By default node process needs to be restarted for picking any change in your JS file. Thus, every time there is a change, you will need to stop node process and start it again.

You can automate this task by using nodemon npm package. This package will monitor any changes and it restart your application

npm install nodemon -g

Once the installation is completed you can start your node process by this command:

nodemon app.js

That’s it!

Now, as soon you will do some changes in your app.js, it will restart the process for you.


Another most important tool that you would like to use during your development is node-inspector. This tool will allow you to debug your node development.

Install this tool by this command:

npm install node-inspector -g

Then call this package with this command:

node-inspector app.js --debug

Another way to run your process in debug is:

node-debug app.js

Using Node-Inspector and Nodemon together:

You can use both packages together by using this command:

node-inspector & nodemon --debug app.js


How can I test query without having any infrastructure?

Well I have faced very similar question on Sqlite. That, how can I check my sqlite query without installing any software?

I came across with the website called

In this website I could select different platform such as Sqlite, mySQL and even postgreSQL.

Here is what I have tried with an example of sqlite:!7/d246c/1
