FastText has recently gained popularity among developers and researchers as the word embedding of choice, alongside GloVe, word2vec, StarSpace, RAND-WALK etc. By default, spaCy expects you to provide a word2vec vector. However, you can use your fastText vectors if you want to!
pyenv build depencies on Ubuntu
pyenv can get particularly annoying during building Python. Dependencies are often missing resulting in failed builds. This short blog post is outlining the required dependencies to reduce headaches for future me, and anyone else reading this.
Using matplotlib alongside OpenCV to render results in Jupyter Notebook. We will be using pyplot.imshow to render images within the browser interface for easier interaction and usage.
Bangladeshi NID and Smart Cards come printed with a 2D Datamatrix Barcode, known as PDF417. The information on the cards can be extracted without using an OCR solution through the barcode. We’ll be using Google’s ZXing library; learn about the basics of using it.
A coin’s faces are marked with 0 and 1. What is the probability of scoring K 1s in N tosses?
Doctests are essentially tests embedded in a docstring. They serve both as example use cases and test cases! A Python expression is provided along with an expected outcome, a test runner collects that and evaluates the expression. This post explains the basics and goes up to using doctests in production.
Simple Python Profiling with IPython
Profiling is imperative to understand your application. However, getting started with profiling might seem to be a steep learning curve; but it doesn’t have to be! IPython has a lot of built-in magic commands, and some of them are helpful to profile your Python code. %timeit and %prun are among the ones I found most useful.
Your application probably does not need to execute some code each time it is used. We have been caching for decades; reducing database queries, using key-value stores, OPcode caching and the list runs on. Things become overwhelming. I believe often we can find the best answers in simplicity; complexity should not be introduced where a simple […]
We all use HTTP, develop for HTTP and think that we know HTTP. But, I believe as engineers we should never take things for granted; rather we should dissect everything that comes before us, recursively as many times as possible. So, let’s keep applying this principle for HTTP.
Often keeping multiple versions of Erlang or Elixir on the same machine might become necessary; also it helps to have the latest versions on your machine as soon as they are released. An amazing tool asdf is capable of doing just that. It makes things as easy as, asdf install erlang 20.3.2 asdf install elixir […]
