Install the WIFI driver for Ourlink AC600 USB Dongle on Ubuntu 20

    It took me a lot of time to figure this out and I thought I would share it with everyone. The driver provided for Linux by Ourlink may not work with the newer versions of Ubuntu. In this article, I am gonna explain how to install the driver and get it working on Ubuntu (I verified on the 20.04.2.0 LTS version).

    Calculate cosine similarities between queries and documents

    In our previous post, we discussed about td-df vectors and how to calculate them. Until now, we learned what term frequency and inverse document frequency are, how they impact the relevancy of a document, and how we can calculate them. Now let’s learn how to calculate cosine similarities between queries and documents, and documents and documents.

    How to calculate tf-idf vectors

    We discussed briefly about the vector space models and TF-IDF in our previous post. In short, TF (Term Frequency) means the number of times a term appears in a given document. IDF (Inverse Document Frequency) means number of documents in which the term appears at least once out of all the documents in the corpus (collection). In the case of IDF, the less documents a term appears in, the more relevant that term becomes.

    Vector Space Model (TF-IDF Weighting)

    Vector Space Model (TF-IDF Weighting)

    Vector space model or term vector model is an algebraic model for representing text documents (and any objects, in general) as vectors of identifiers. The representation of a set of documents as vectors in a common vector space is known as the vector space model. It is fundamental to a host of information retrieval operations ranging from scoring documents on a query, document classification and document clustering. It is used in information filtering, information retrieval, indexing and relevancy rankings.

    How to store file in bluemix storage using python

    How to store file in bluemix storage using python

    IBM Bluemix is a cloud platform as a service (PaaS). It supports several programming languages like Java, Node.js, Go, PHP, Python, Ruby Sinatra, Ruby on Rails. In this article I am going to describe how python can be used to store/delete files in bluemix object storage.

    Two-finger scrolling : This is how you enable it in mint

    Two-finger scrolling : This is how you enable it in mint

    You buy a laptop, install linux mint or any cinnamon desktop, and you realise that the two-finger scrolling is not working. It can be quite frustrating at times. Especially when you have been using that feature for some time. But did you know, the feature in inbuilt in linux mint, just not activated by default?

    Ever wondered how data compressions work?

    Ever wondered how data compressions work?

    All of us who use computers have used data compression, whether doing it ourselves or using a compressed file. Sometimes the compressed data or files are apparent while sometimes do not seem that way. The gist of compression – it shouldn’t seem like it has been compressed. JPEG is an extremely popular type of image compression technique and so are PNG, MP3, MP4 or MKVs.

    He had been a vegetarian for more than 15 years. He wouldn’t even eat a chicken flavored noodles (which doesn’t even have actual chicken in it).
