DevOps Success Stories in the Financial Services Industry
5 hours ago, dzone

DevOps is making its impact on almost every software powered company these days, and that being said, when it came to companies in the finance domain, they were perhaps the slowest to embrace DevOps. But it is safe to say that they are currently leading the digital innovation in this sphere of cloud-native technology. The initial hindrance towards DevOps in financial institutions was because of the principles they adhere towards governance, security, compliance, and regulatory regulations.  Why ...

Import Projects From Git Into Eclipse As a VCS (Version Control System) I’m using git in all my projects. And not only for software or firmware projects: I’m using it for hardware design (KiCAD, FreeCAD, …) or for documentation (LaTeX, …) too. The nice thing with the Eclipse IDE is that it supports nice git integration, making importing projects from git repositories easy....

In this post, you will learn the concepts of Adaline (ADAptive LInear NEuron), a machine learning algorithm, along with a Python example. Like Perceptron, it is important to understand the concepts of Adaline as it forms the foundation of learning neural networks. The concept of Perceptron and Adaline could found to be useful in understanding how gradient descent can be used to learn the weights which when combined with input signals is used to make predictions based on unit step function outpu...

Increased Complexity of C++20 Range Algorithms Declarations — Is It Worth?

Amazon Aurora Multi-Primary First Impression
15 hours ago, dzone

For what reason should I use a real multi-primary setup? To be clear, not a multi-writer solution where any node can become the active writer in case of needs, as for Percona XtraDB Cluster (PXC) or Percona Server for MySQL using Group_replication. No, we are talking about a multi-primary setup where I can write at the same time on multiple nodes. I want to insist on this "why?"....

Redis Is Not Just a Cache
15 hours ago, dzone

Do You Always Need a Classic Database? For some time now the huge amount of data that needs to be processed forces any app to have a caching strategy in front of the databases. The databases, even with huge underline optimizations, can’t always provide enough speed and availability. The main reason is that the farther is the data, the harder it is to access it. Another reason is that usually, a database persists data on disk and not on RAM. They do have embedded cache on RAM for increasing the o...

How To Land Your First DevOps Role
19 hours ago, dzone

DevOps was undisputedly one of the tech buzzwords of the 2010s. Starting as a relatively obscure methodology orbiting a few open-source tools, DevOps teams are now a fundamental part of most organizations. There’s a good reason too. Well executed CI/CD pipelines have made companies billions. Even at a smaller scale, the time and energy saved by a solid automation process enable much more productive work to be carried out by developers and engineers. The business impact of a strong DevOps practic...

Dev methodology mostly doesn't matter (so just make up your own)
19 hours ago, dzone

A waterfall of old-schoolness I worked as a developer using Waterfall for exactly 9 months. I was 22 years old and it was my first programmer job and first corporate environment. This place was old school. Like suit-wearing, personal cubicle type old school. Our CEO would hold all-hands meetings where everyone was required to stand the whole time and he would call people up to give speeches at random because he believed everyone should be good at public speaking....

Today, I will discuss another structural design pattern - Proxy Design Pattern. Proxy means an object functioning as another object. Proxy Design Pattern The Proxy Design Pattern is a Structural Design Pattern and one of the Gang of Four design patterns.  The Proxy Design Pattern gives a way to create a class that represents the functionality of another class. The Proxy could interface to anything; a network connection, a large object in memory, a file, or some other resource that is expensive...

What's Wrong With Big Objects In Java?
20 hours ago, dzone

By design, the G1 garbage collector manages the heap by dividing it into a fixed number of same-size regions. By default, the maximum number of regions is 2048, and region size corresponds to the maximum heap size as follows: heap size < 4GB: 2MB, <8GB: 4MB, <16GB: 8MB, and so on. Normally objects are allocated into a given region until it's full, and then at some point, the GC frees up the entire region by evacuating all live objects from it. All these changes, however, if an object (typically ...
