This contest started as a fun chat with an employee at HackerRank and how it ended up with a coding contest. One of the engineers from our team, Aditi Tayal, has recently started learning to build a web app using Mysql and Redis. She built a simple task manager and shared this link with me https://aditiflaskcrudapptutorial.herokuapp.com/. My first instinct is …

There is a lot of interesting items going on to make the web page load faster. font-display: swap Instructs the browser to use the fallback font to …
This post is the result of writing a LOT of Google apps scripts and watching a lot of ‘Forensic Files‘ in Netflix. An interesting function I used so far to attach a menu is the onOpen() function. The code inside the onOpen() function executes when the file is opened. For example, following code is an example of onOpen from my …
I’ve always enjoyed the commencement speech made by Steve Jobs at Stanford. It is everyone out there should listen at least once. You can read/view the entire speech here at https://news.stanford.edu/2005/06/14/jobs-061505/. The best part about the speech is about he finished the speech. When I was young, there was an amazing publication called The Whole Earth Catalog, which was one of …
Mail merge is a great feature (truth be told, everything that automates a repetitive job is a great feature). One of the tedious repetitive task our team keeps doing often is generating PDF files for our employees (usually one file per person). We are going to automate this using Google Docs, Google Sheets, and Google App Scripts. Step 1: Create …
Top three things I want to remember from this book and hopefully follow in work and life. It is not easy to build a team on top of honesty and candor. This is not because people are bad or not trustable. We slowly lose the honesty and candor as we grow big. We all try our best to avoid hard …
Given the current COVID-19 scenario, this is the right time to measure the mental strength of companies and individual members. Here is a good video to understand why mental strength matters. While it is fun to make such adorable videos, that is not the core reason for this experiment. The researchers studied these children years later as a follow-up study. …
One of the downsides of running a company is that you get caught up with so many problems to solve ‘at this moment,’ that you miss the focus to think long term. Especially one of the things I miss the most is reading books and reflecting on the learnings. It is easier to take your time off to read books …
9 years since I’ve decided to start on my own. Looking back, not a bad decision after all. Looking ahead, excited only about two things. People I’m working with and the problem I’m solving. More and more interesting people to work with. The scope of the problem to be solved is getting bigger and bigger. #excited! Photo by rawpixel on Unsplash
There are a lot of ways to define a startup. Paul Graham defines a startup as growth. This is how I would define it. A startup is an interesting & brutal game. The reason why it is both interesting & brutal is that the rules of the game keep on changing. Every 2 or 3 years, almost the entire rule set …
The answer for the above question was always “Vivek & Hari”, but not anymore. To give an idea on from when to when we built things and now who is “actually” building the company. From June 2009 – December 2011 From Jan 2012 – Today. There were many other smart programmers we hired, fired/quit. They did help us grow …
Start as if you are going to stick to it for the next 10 years. Hire as if you are going to quit in the next 3 months. Status check: Part 1 – Done Part 2 – In Progress
A few days ago, a website (hmm, not just any website though) happened to mention my name in one of their posts. A lot of people congratulated (for what) and some even said “You should be so proud now”. Well, to tell you the truth I wasn’t. In fact, for that matter, I don’t think I’ve ever been proud of anything except …
If you are serious about customer support, then you will wake up in the middle of the night, search for your mobile phone and your heart should skip a beat when you don’t find it next to you. When you finally find it next to your laptop on your table, with no missed calls from your customers (thank god), you …
When I used to work from bangalore, I had this 300 pages notebook. I used to carry it everywhere and write my TODOs. I stopped using it after I moved to chennai. I happened to get a look at this notebook after a long long time and boy, how much I’ve scribbled. Note : Most of the notes is about …
Very rarely, you will want to delete all friends from Facebook and start a “fresh” facebook account. Now, it’s hard to do this manually. Thanks to phpunit + selenium + a few lines of code, this can be done now. The following script removes all your friends from facebook 🙂 Replace and with your username and password respectively. <?php require_once ‘PHPUnit/Extensions/SeleniumTestCase.php’; …

Hiring good candidates is a problem for every single company out there.. no matter small or big. We at interviewstreet attack the tip of the iceberg by filtering good programmers from the rest. People say, it’s a huge timesaver ;-). But enough about interviewstreet, the first problem companies should tackle is to make sure rockstar hackers apply for the job. …
HTML5 seems to be the buzz word now. People around me are excited about HTML5 or already working on something with HTML5. Curious to know what the hell is this HTML5, I started reading something from https://developer.mozilla.org/en/HTML/HTML5. Well, truth be told, I finished the overview in say 15 minutes and didn’t know what exactly to do after that. I was …
More than an year since I’ve quit IBM and into startup world. Too many things to write.. Things moving at such a rapid rate that if I write something today, tomorrow it might not be valid or correct. Makes me stop and think at times whether what I’m doing makes sense, is it the right path or am I yet …

We use Git here at interviewstreet. Using Git, branching, testing and reverting is so easy. Almost all commands are simple and easy to remember in Git, except for deleting a remote branch. The command to delete a remote branch “feature1” is git push origin :feature1 Just wanted to note this down.
The problem statement is as follows : The Playfair Cipher encrypts text by substitution of digrams (2-letter groupings). It is traditional to use a 5 x 5 letter scrambled-alphabet key square for the encryption and decryption. Each letter of the alphabet appears once, except “I” also represents “J”. The arbitrarily chosen key word, “CODES” comes first, then all the rest …
