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...

All you need to know about ProtoBuf

Google's ProtoBuf aka Protocol Buffers has been there for a good while now. It is free, open-sourced, data serialization format. But why use this? Because it is language agnostic, platform-neutral. And in comparison to text based format like json, it is extremely fast and compact. Lastly, it eases your development and maintenance endeavors too. How easy is it to work with? Start by defining your DTO (Data Transfer Object) to be passed over the network in a `.proto` file. Use protobuf compiler to generate corresponding source code of the DTO in language of your choice (protobuf supports many popular languages). You are now ready to use this generated source code in your project. If you come across a need to change the DTO structure, repeat the process 1-3 again. When to use it? Now I prefer REST/JSON format for most occasions to maximize the advantages of HTTP infrastructure. And then there are occasions, I prefe...

Python Development Tools You Must Leverage For Productivity

It's been more than a while since I coded on a Python project. I happened to pick one in the recent past and started revamp the project with my opinionated tool set for good productivity and safety while refactoring the legacy code. So here goes my toolset that I believe you too must think of adopting today, if you have not already done it: I prefer PyCharm over VS-Code . You would start respecting it as your project grows in complexity or when you have to refactor your code confidently at speed. If your project demands document generation for your classes and methods, Pycharm generates it in a flash. Besides, I customize Pycharm settings further to truncate line-ending whitespaces, code-folding, etc. to suite my coding style. Developer-Readme.md is one of the often overlooked thing that I insist in for every single project repository with details on developer-setup instructions, project specific wo...

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:

AWS Cloud Services Marked For Sunset By 2024 Year-end

AWS Cloud services is going through an overhaul in the past couple of years with the sunsetting of even some notable service. Listed below are some of the notable services that are marked for sunset latest by the end of year 2024: AWS OpsWorks: is a managed service for Chef/Puppet, a configuration management tool. It has reached its end of life in AWS Cloud. AWS Cloud9: is a cloud-based integrated development environment. If you are still using it, you may want to consider checking out their blog post titled, " How to migrate from AWS Cloud9 to AWS IDE Toolkits or AWS Cloudshell ". AWS CodeCommit: is a serverless version control repository service and AWS has recently cut out access to it for new customers and that implies it is marked for sunset. You can confirm this from its VP Jeff Barr's tweet , if you were to follow him. They later published a blog post titled, " How to migrate your AWS CodeCommit repository to another Git provider ", that should be o...
