Go vs Python: Parsing a JSON response from a HTTP API

As part of a recommendations with Neo4j talk that I’ve presented a few times over the last year I have a set of scripts that download some data from the meetup.com API.

Mathematical Modules in Python: Random

Nearly all of the functions in this module depend on the basic random() function, which will generate a random float greater than or equal to zero and less than one. Python uses the Mersenne Twister to generate the floats. It produces 53-bit precision floats with a period of 2**19937-1. It is actually the most widely used general-purpose pseudo-random number generator.

Changing numbers Sign in Excel – From Negative to Positive and Vice versa

Another question to answer and very interesting one indeed. Again this question came from our vibrant facebook community. The requirement is to change number signs that is change negative numbers to positive and positive to negatives. Although this is hardly the case in many situations that you really want an additive inverse for each and every value as most of the time users want all the values to be positive or all the values to be zero but in real life all sorts of things happen.

Spring Cloud Sleuth in a Monolith Application

In this article, we’re introducing Spring Cloud Sleuth – a powerful tool for enhancing logs in any application, but especially in a system built up of multiple services. And for this writeup we’re going to focus on using Sleuth in a monolith application, not across microservices. We’ve all had the unfortunate experience of trying to diagnose a problem with a scheduled task, a multi-threaded operation, or a complex web request. Often, even when there is logging, it is hard to tell what actions need to be correlated together to create a single request.

How to Use a JavaScript DataTable in an Angular Application

There are several data table widgets for Angular, but none of them matched our project’s needs. I’m sure that’s simply a matter of time. Angular2 is young, and the third-party libraries are even younger. They simply didn’t have enough time to accumulate features and maturity. So why don’t we use one of the seasoned JavaScript data tables?
 

Photographing Beautiful and Monstrous Waves

I've lived on the shores of Lake Erie my entire life and can readily attest that it can a very unkind body of water. Photographer Dave Sandford takes advantage of this by wading into the tumultuous waves to capture and showcase their beauty. We've featured Sandford's amazing work before, and it's great to hear him talk about his process and the ups and downs (or should I say "crests and troughs") of standing in freezing cold water to capture those "liquid mountains that literally last all of a second."

Dodge and burn tool

Welcome to my another tutorial from 30 Days to Learn Photoshop series. Last time we discussed Gradeint Tool in Photoshop and today we’ll discuss Dodge and Burn Tool in Photoshop. Dodge and Burn Tool give us a better control on highlights and shadows of the image. Of course, you can use your contrast bar but that feature gives us very less flexibility. All you can do is to move the slider. Dodge and Burn tool gives you full control over the image. It takes a whole lot of time, effort, and skills but the results are much better.
