Phases In The Life-cycle Of An Equity Order

Retail equity investors or traders place orders to buy a specific quantity of a specific stock at a specific price point/threshold within a specific time frame. The stock trade happens in trillions per day in a country like India, and the transactions happen in just a few seconds with quite a deal going under the hood from the time an order is placed to the time it is completed. This post details the life-cycle of a typical equity order from the time it is placed in an app by an investor to the time he get to see that the order is "complete" to learn of its status. Below are the 10 phases in the life-cycle of an equity stock order from the time it is placed by a customer on their app: (Trade) Order Placement: Customer places a buy/sell order on their trading app or platform. Order Validation: The broker platform's Order Management System (OMS) validates the order details (like symbol, quantity, price, etc.) against customer account details (like balance, position etc).

Should I buy refurbished laptop from Amazon?

This post is based on my experience with amazon.in and guess it to be true on all other platforms as well. At least you can check out and verify for these pointers before you make that decision to buy renewed/refurbished laptop on Amazon with your hard earned money. I see this question propping up in several forums and on many different occasions. In the recent past, I had my 5 year old dell laptop that gave up because its motherboard failed. One of the options that I had in my mind was to re-use the HDD and the 16GB DDR4 RAM of that old laptop in the one that I purchase next as secondary. I had come to a conclusion that it is not worth buying a refurbished/renewed laptop at all. Why? For the following reasons, most of which I see as BIG #RedFlags: You got to remember that Amazon provides a platform for 3rd party sellers to sell their products as well. So in your search for refurbished laptops you wouldn’t want to choose some random 3rd party seller who Amazon doesn’t endorse. You cou

Android Activity's onDestroy() Ain't Your Reliable Friend

Look at the Android Activity life-cycle events in the picture beside. The lifecycle isn't something new. You're familiar with it right? You're also that good Android developer that writes clean code, wherein you consciously override onDestroy() method to include resources clean-up code and save some state, right? Per Android doc , it is okay and usually the practice to write cleanup code in this method but not anything beyond that. So if you are to write code to persist state in this method, or anything else beyond resource clean-up (like threads associated with an activity), you're better off to push it up the life-cycle, either in onStop() or onPause() method. That is how I settled in the first iteration of new learning but wasn't happy. Why? To quote Android Doc:

How to disable gnome-ssh-askpass?

Today we had setup Git repo with access to it through corporate's LDAP authentication. From the client machines we can access it using the .netrc (where the machine, login and password are configured). However, for some wierd reason, upon trying to pull/push commits from/to the Git repository, the bash shell tries to open the gnome-ssh-askpass dialogue and it fails. I wanted to prevent the bash shell from attempting to launch the dialogue box. To do this, all I had to do is run the following command in the terminal: $ unset SSH_ASKPASS To prevent it in future, you can add the above line in your .bashrc or .bash_profile. Wish you trouble-free working!

Book Review: iWoz

This book is an autobiography of Steve Wozniak, technical co-founder of Apple. Have you read an biography book with a Glossary of jargons? This book has it with tech jargons for non-engineers to digest, which looks like a prank on non-engineers wanting to read this book. The readers either get it or don't. This is a biography of a geek engineer for a geek engineer, more so in my opinion for high schoolers and graduate engineers who can draw some inspiration out of the good parts of his life lessons leaving behind the unethical or illegal ones (Woz while admitting it to be illegal was admittedly frank to open it up to the world, albeit not considering it a crime from his worldview which is something you the young readers may want to be wary about). On the other hand how he didn't do drugs for the sake of getting along with the hippies he liked much is an interesting bit in the sense that the young can take that as an inspiration for not bucking down to social/peer pressure.
