Deletion of a document

    The deletion of a document also updates the version of the document. For example, if the _version of the document with the _id 1 was 3, after a successful deletion, the _version will be incremented to 4. When a document is deleted, it is not deleted immediately, it will be temporarily marked as deleted. At this point, the document won't be searchable. After some amount of time, the Elasticsearch garbage collector collects the documents which are marked as deleted for permanent deletion. If the same document is indexed or updated with the same _id, the document will be resurrected and the _version will be incremented by 1. This is of course not expected at all. This can lead to some unexpected behaviors. 

    The time after which the documents are picked up for permanent deletion by the Elasticsearch garbage collector is set in the _settings field called gc_deletes. This is set to 60 seconds by default during the index creation. This can be changed dynamically, after the index creation also using the following query:

    Though thinking of speaking fluent Japanese or Spanish seems mouth-watering but thinking to learn it is not. But this the time where you can take a Udemy course and learning it. You have all day to practice and clear the basics. To make it legit, you can take certification exams which can help you in your career.

    If you want to switch careers or you are a student, learning to code can always pay you dividends.  There is plenty of free stuff out there like freeCodeCamp and many others which can help you to learn how to code. The professionals who want to upgrade their skills can also use this time to learn new technologies and upgrade their skills. BTW, this is my personal favorite.

    Since you have plenty of time at your disposal, you can prepare for job interviews to land your dream job. Start by updating your resume or CV and updating your online job profiles. Prepare well and land your dream job.

    If you are like me with a big belly and you are always jealous of looking at others who are fit and confident, then we need to have a talk. Start by simple work out routines at your home. You can do yoga, meditation or intense workouts like Tabata or HIIT. I am personally following Tabata 5 min workout and I do yoga and Pranayam every morning. Also, keep yourself hydrated and eat healthily.

    If you are a book worm, then you can skip this tip. But if you are like me for whom the reading book is the last thing that you wanna do, you should at least give it a try. I have started reading books and very soon realized the power it possesses. If your brain is a sword then you need books to sharpen it. Its never too late to start. Don't miss out on this wonderful thing.

    I am not a very good writer but I have started a blog and started to share what I know. Similarly, you can also start it. Share what you know or what you are good at. Don't do it for appreciation, but for your own satisfaction. You can also start a YouTube channel.

You can write what you do to keep yourself productive in the comments.

The Coronavirus (COVID-19) has been tough for everyone. From health workers to vegetable vendors to daily wage laborers, everyone is suffering. Though software developers and people associated with IT industries have all been given instruction to work from home (WFH), but this can be challenging as well as tricky to give your 100% to your work and stay productive.

So, here I am sharing with you how to be productive in these tough times

   For many people, this time can be the time for enjoying and fooling around. They think that since no one is there to monitor what they do or have done, one can easily lose focus. The trick is to think it as a normal day where you wake up early, get ready and go to your office. The only thing missing here is the last part, others need to be the same. Start working when your office starts and stop when it stops. Sleep and wake up on time. Don't mess up your biological clock.

  The ones who struggle a lot to focus can trick their mind in believing that they are at their office working. Our brain associates the dresses that we wear with the things that we do. You will find it very hard to sleep on your work dress. So, don't work wearing your pajamas and t-shirts.

  Productivity and focus also depend on where you work. Try to make your work desk as minimal as possible. Only keep the things that you absolutely require. The workspace must be at a very quiet place and try to set up your desk near a window where you can enjoy the sunlight and cool breeze. This will keep your mind active. If you have plants, keep it on your desk or near you.

  Try to take short breaks in between your work. You can work for say 20-25 mins with absolute focus and take a rest for 5 mins. Keep a bottle of water near you and keep yourself hydrated all the time. Try not to indulge in work during your usual lunch break. Eat well without any disturbances.

  Work out or do yoga or any kind of physical activity in the morning or evening. During the break try to do desk exercises or take a walk around the house or garden if you have one. Meditation also helps a lot to concentrate and overall well being of the mind.

  Staying happy and content with where you are and what you do is the key to a healthy and happy life. Stay away from hateful content on any type of media. Play with your siblings or kids or pets. Talk with your friends, relatives and loved ones over the phone. This is the time to call your old friends which you haven't talked to since ages 😊

 Though it is not easy to stay happy and focused during these tough times. But life goes on and you also have to. Make the most of this time and make it the best time of your life.

Hi! This is my first post on this blog. I am currently working as a software developer in a firm based in Bengaluru, India. I have started this blog for sharing what I know, from technology to life tips to my experiences on various arrays of things.

I have started my journey as a software developer from a small town in the foothills of Eastern Himalayas where I completed my schooling and engineering. I always wanted to do something with computers since my childhood when my father bought an HP desktop computer. I used to play games on it, open it up and upgrade it, and literally live with it 24/7. It was my first child. I was always fascinated by how things worked inside it which made me take computers as my major in engineering. After completing my engineering, I moved to Bengaluru or Bangalore which is about 3200KMs away from my home. I got my first job in a startup which in time of writing this post is my current job.

Besides computers, I always wanted to make myself as productive as I could. This didn't start till my first job where managing time for learning and fun, between a very hectic job, was getting very tough. I wanted to learn as much as I could, have fun with my friends and still be productive in my job also. I had to make drastic changes to my lifestyle. I was wasting time partying with my friends on weekends and working about 10-12 hours a day and come back home tired and weak.

2020 was a year that I thought can be a start for all that I wanted to become and achieve. So, I started with meditation, reading books, working out and quitting alcohol for good. I didn't want to stop there. I always wanted to have a blog or website where I can share my knowledge (at least whatever I know 😉). This can be a place where I put whatever I have learned recently or a long time back. This can be my notebook of learning.

So, here we go ... !!! 🙏🙏🙏
