GraphQL is an amazing specification, no doubt about that. I loved it when it first came into my knowledge but as I started learning it, well, I started to hate it and I still do at some extent because I am still learning it. So much boilerplate code to even starting the graphQL server.
Introduction
According to Wikipedia, Software profiling is a form of dynamic program analysis that measures, for example, the space (memory) or time complexity of a program, the usage of particular instructions, or the frequency and duration of function calls.
AWS data pipelines are one of the best mechanisms to transfer data from one storage to another storage with a different data type. While transferring data from pipelines, there are several techniques which can be used to optimize the process of copying data. In this article, the scenario would be copying 3 CSV format files which are stored in S3 bucket, to 3 Dynamodb tables.

Ruby on Rails is a tremendous framework when you want development speed for your project or startup. It’s useful right out of the box and comes with a plethora of behind-the-scenes magic to make your life easier. However, it’s not considered the fastest framework out there in terms of performance. You will find examples of individuals and companies drifting away from Rails in favour of something else. Despite this, there are many companies out there who have succeeded in scaling Rails and found success — just take a look at Airbnb, Github, Gitlab & Shopify.

We are in the age of the Agile revolution, even non-tech companies and non-tech departments are adopting agile practices and frameworks. The issue is that organizations are making these adoptions without changing the foundation that their companies are built on. One of these major pillars is performance appraisals and it is critical because it is very important to employees. We all want to do well, and get big bonuses, or even get that promotion that we have been working so hard towards. The issue is most companies do not have the Agile mindset and focus mainly on the individual and neglect the team aspect when it comes to performance. This directly hurts organizations that are looking to build mature Agile teams.

We used to think that the secret to getting better at anything was directly linked to the timed dedicated to practice (we’ve all heard about the 10, 000 hours that stand between us and achieving mastery in any field) but, as in turns out, it’s not how much we practice but also how we do it. According to psychologist Andres Ericsson, “deliberate practice” is what matters and makes a huge difference in achieving expert performance.

I want to talk a little about how you can use content-based addressing (aka data fingerprinting) as a general approach to make your applications faster and more secure with some practical JavaScript examples.
The High Resolution Time standard defines a Performance interface that supports client-side latency measurements within applications. The Performance interfaces are considered high resolution because they are accurate to a thousandth of a millisecond (subject to hardware or software constraints). The interfaces support a number of use cases including calculating frame-rates (potentially important in animations) and benchmarking (such as the time to load a resource).
Using data from database collections or from a 3rd-party source can be a powerful tool to enhance your site's functionality.
