Tableau Hierarchy – the Better Way

A hierarchy feature can make your data well structured and let your users intuitively interact with it. Nothing can’t compare to a great usability and overall UX, however, the native implementation of the hierarchy feature in Tableau doesn’t really help with that. In fact, your users will have to find that minute “plus” sign on the corner of the table before they can see the result. That might not sound as bad for people familiar with the feature but for the rest this means poor user experience. Does this mean you should give up on hierarchy? Not at all! You just need to make the use of it intuitive. Let’s give it a shot!

What Data Visualization Tool Should I Use?

Data visualization tools transform data and information into accessible visual representations like graphs, maps, and charts. These tools make the data we generate more accessible to us because humans are fundamentally visual creatures. One study found that we process visual elements a whopping 60,000 times faster than text.

How to Deploy AWS Lambda over 250MB in Size with Serverless

AWS Lambda is a great serverless solution by itself and together with Serverless, it is easy to develop and deploy cloud applications. Lambda is great but not perfect as it comes with its own set of limitations. One of which is size – the total size of the deployed unzipped package cannot exceed 250MB.

Which Database Should I Use?

Databases fulfill a vital role in our businesses. They allow us to maintain, update, and edit our stored information quickly and securely. We use databases for a wide variety of data storage needs like inventory tracking, customer relationship management, payroll, data analysis, networking, and much more. Doing this efficiently means we can support the wider business functions and help the company excel at its goals.

Connecting AWS Lambda to MySQL

Connecting AWS Lambda to MySQL via ODBC (PYODBC)

Running your code serverless in Lambda is great: it doesn’t require resource provisioning, managing a server and you pay as you go. Is it perfect? Not quite. Among the other issues natural to any serverless implementation there is one with… drivers, of course. With traditional implementations drivers are installed across the entire system, which is no problem as they are centrally registered and referenced. With serverless deployment, however, the references are broken which inevitably leads to some noticeable pain in the neck. Something I have experienced firsthand not so long ago while trying to deploy Python Lambda with MySQL ODBC connection (using pyodbc).

ARTIFICIAL INTELLIGENCE (AI) & VIRTUAL REALITY (VR)

In recent times, artificial intelligence has taken the field of healthcare by storm with its precise diagnostic skills in deploying more detailed, resourceful, and impactful interventions in patient’s care. There has been talks of AI doctors ousting human physicians in the future, this is highly unlikely but what would rather play out is AI doctors providing quality help to assist physicians in making better clinical decisions or even take charge of some decision in certain critical healthcare fields like radiology.
