Learning Mandarin, My 3rd Language

Mandarin is indeed an amazing language to learn and explore. It is one of the last surviving pictographic languages, and as a language enthusiast, this might get you excited! 1.3 Billion people and a lot of my neighbors know Mandarin – a good enough reason for me to pick it up!

Encoding Bangla (Unicode) SMS for SSLWireless in Python

If you are wondering why you cannot send Bengali text encoded in Unicode properly through the SSLWireless Push API in Python, well you are not alone. The solution is, encoding your UTF-8 text into UTF-16 (Big Endian) and then taking the hexadecimal value of it, transformed into uppercase.

BSc in Computer Science Distance Learning at UoL: Why I chose it

I am a self-taught Software Engineer working in the industry for about 5 years. However, formal tertiary education has always been on my radar. This blog post describes my story, and why I chose a distance learning programme instead of an on-campus offering.

I didn’t “Hack” Your Site

If you are seeing my website instead of the one you’re supposed to see, this post is for you. I sharing a hosting server with several hundreds of people. That server had a hardware failure, and backups are being restored as I speak.

Why are you seeing my site?

My Domain starts with the letter A. Thus, it was copied to the server from a backup first. Even before the default file, as it starts with D. So, for a brief period, you saw my site. Till that default got copied over.

I didn’t hack you.

Please contact your hosting provider.

Categorical and Numeric Data in Scikit-Learn Pipelines

I always tend to organize every aspect of my experiments with organizers as useful as Pipeline. However, one shouldn’t be passing continuous variables into a OneHotEncoder or vice versa for Scalers.

Counting Weekends between Two Dates in PostgreSQL

I found myself the problem of counting the occurrence of specific “days of the week” between two dates; for, of course, generating features for a predictive analysis task. For example, the number of Fridays and Saturdays between 2019-01-01 and 2019-01-15. And thankfully, good old PostgreSQL came to the rescue!

Collecting Documents for Transferring from NSU

GP launched 013: Update your RegExp!

Grameenphone quietly rolled out its 013 series of numbers and it wrecked everything. No web service, including Google is working with this 013 series of numbers. Its time for developers to fix this mess and update every validation logic you may have for validating mobile numbers or MSISDNs.

I enlisted a few RegExps for de-terrorizing you, even if a bit.

01[35-9]\d{8}

Enough reading, update your RegExps now!

Flask-like “global” request context in Sanic (asyncio)

Although something like Flask’s globally accessible request object is considered a terrible way of writing code (explicit is better than implicit), sometimes it makes sense to use it. For example, while passing a Correlation-ID to track a request’s life cycle through your micro-services.
