On working remote

The last company I worked for, did have an office space, but the code was all on Github, infra on AWS, we tracked issues over Asana and more or less each person had at least one project they could call "their own" (I had a bunch of them ;-)). This worked pretty well. And it gave me a feeling that working remote would not be very different from this. So when we started working on our own startup, we started with working from our homes. It looked great at first. I could now spend more time with Mom and could work at leisure. However, it is not as good as it looks like. At times it just feels you are busy without business, that you had been working, yet didn't achieve much. If you are evaluating working from home and are not sure of how to start, or you already do (then please review and add your views in comments) and feel like you were better off in the office, do read on. Remote work is great. But a physical office is better. So if you can, find yourself a co-working s

15 minutes of courage

"I Quit" , said she and walked out as briskly as she could, her face as stern as a stone. She didn't look back. I wanted her to. I felt helpless, somewhat creepy, and a sudden chill went down my spine. I didn't know what to do. I wanted to just run away. Run away from her. Run away from this world. Run away to some distant place where I could be myself. Some place where I could cry to my heart's content. But I was not one of those who would leave the ground, wounded! I had always been the one who took life head on. So was it the time to lean back and contemplate what actually went wrong? No. That won't be the man, the world knew! So.. was it the time to build a castle around my feelings and play cold? ~ Prince Mishra

How the Python import system works

How the Python import system works From:  https://tenthousandmeters.com/blog/python-behind-the-scenes-11-how-the-python-import-system-works/ If you ask me to name the most misunderstood aspect of Python, I will answer without a second thought: the Python import system. Just remember how many times you used relative imports and got something like  ImportError: attempted relative import with no known parent package ; or tried to figure out how to structure a project so that all the imports work correctly; or hacked  sys.path  when you couldn't find a better solution. Every Python programmer experienced something like this, and popular StackOverflow questions, such us  Importing files from different folder  (1822 votes),  Relative imports in Python 3  (1064 votes) and  Relative imports for the billionth time  (993 votes), are a good indicator of that. The Python import system doesn't just seem complicated – it is complicated. So even though the  documentation  is really good, it d
