[interview] The modern art of data transformations — how data engineering unlocks information potential

By 2025, global data creation is said to exceed 180 zettabytes. In 2020, we had already consumed and created more than 64 zettabytes. These data carry information that can put any business ahead of its competition. But how to take advantage of data effectively and use it to improve products, services and meet modern customers' needs? In this interview, we'll discuss the importance of data engineering with Tomasz Jędrośka, Head of Data Engineering at CodiLime. Tomasz's role is to grow this relatively new division of the company and make sure it delivers competence synergies with our Networking, Cloud, and Security services and therefore extend further CodiLime’s competitive advantages.

[interview] How to use data to navigate complex systems better? Talking about monitoring and observability.

In today's constantly developing technological landscape, businesses are looking for solutions that help them manage complex systems and ensure optimal performance. However, although 90% of IT professionals believe observability is important and strategic to their business, only 26% said their observability practice was mature. Why this difference? What are the reasons why businesses don’t manage to implement monitoring and observability at a high level? In this interview, we explore the significance of monitoring and observability - our guests Edyta Kałka, Senior Engineering Manager, and Maciej Manturewicz, Director of Engineering, will share their insights, real-world experiences, and opinions on how to create effective monitoring and observability solutions.

Why service mesh matters: understanding the benefits of microservices networking

Building applications as distributed systems, especially with microservices architecture, is quickly becoming the new norm of software development. Microservices, when used in the right situation, can ensure that your application will be easy to scale, update, and fix. If you aim to create a cloud-native app, then microservices are typically your best choice. However, when you start looking into distributed applications, one potential problem stands out, and that is the issue of communication between the multiple services in your application.

AI & machine learning for networks: example use cases

In today's digital age, the use of machine learning (ML) in networks has become increasingly prevalent. Modern businesses rely heavily on networks to maintain operations. However, it could be more and more challenging to manage network infrastructure effectively. One solution is to use machine learning (ML) algorithms to analyze network data and provide insights that can lead to more efficient network management. In this article, we will explore several ML use cases in network management including time series forecasting, capacity planning, intelligent alerting, and the use of external data to enable faster recovery of network components.

Top 7 code coverage tools for Java

It is not a secret that writing code can sometimes take less time than making sure it works correctly. Running tests is crucial to guarantee the new build of your software has a successful release. Automating this task can save a lot of time for your developers and reduce time to market. But how can you be sure the tests you run are efficient enough? It is logical to strive to test as much of your code and as thoroughly as possible. That is why, for example, unit testing is used; it allows testing of smaller, logically isolated pieces of code like a property or a function.

FPGA in network solutions: benefits and usage examples

Silicon chips are a well-known and traditional resource often used in projects. However, sometimes they can be insufficiently flexible – here, the FPGA comes in. This solution is gaining popularity as FPGAs provide more options for customization. If you are looking for more information about FPGAs, their strengths, and in which types of projects FPGAs will work better than other solutions, this article provides the answers. We also offer examples of how we have used FPGAs in our clients’ projects. A small annotation: to better distinguish FPGAs from silicon chips, the term “silicon solution” is used in the article.

CI/CD tools in DevOps — which should you choose?

Automation is now a must in software development if a business wants to keep pace with dynamic market trends and customer needs. It helps with process optimization and makes the most of the budget. DevOps is an approach that allows businesses to achieve these goals as it implements a set of norms and practices. However, to make the final product really stand out, it is worth supporting the process with tools that facilitate DevOps engineers' work. CI/CD, or Continuous Integration (CI) and Continuous Delivery or Continuous Deployment (CD), is one of the core paradigms in software development that benefit both process and business, thanks to its focus on delivery and quality.

An introduction to low-level programming

A programming language could be described as a way of translating a programmer's intentions into machine code that can be understood by a processor. There is much information about high- and low-level programming languages available from various sources. How to tell them apart? Low-level programming languages allow for unambiguous and precise control over exactly what machine code will be the result of a compilation. In high-level languages, the algorithms select the instructions, often simplifying them and not allowing for their modification.

Why Golang may be a good choice for your project

Go (or Golang) is an open-source programming language originally created by Google that has been gaining in popularity due its high performance, expressiveness and readability. This blog post will describe the Go programming language’s origins, main features, and advantages for programmers and businesses. At the end of the article, you will find the use cases where Golang works best. When Google was growing exponentially, it had to deal with problems of scale. They simply had lots of everything: tens of thousands of engineers, lots of software and systems, millions of lines of code (especially behind their network servers) being developed by hundreds of programmers, and finally lots of hardware on which all this software was launched.

Day 0/Day 1/Day 2 — the software lifecycle in the cloud age

The topic of "Day 0/Day 1/Day 2" in the context of the software lifecycle is very prominent in the professional IT media today. Presentations and conference talks are often focused on making software development processes effective and easy to manage. To do so, it is necessary to clearly define the notions that are used. The basic terms "Day 0/Day 1/Day 2" are often understood intuitively, which can introduce some ambiguity when talking about the software life cycle. For that reason, I have decided to define them more accurately to show the entire process of software development and how they are used in real projects.

MobX in React — learn the basics [Video Demonstration]

MobX and React are often used together to efficiently create component-based web applications. The process of integrating them can seem challenging at the beginning. This is why we haveprepared a comprehensive video guide for those who want to use MobX in React. Also known as React.js or ReactJS, React is an open source, JavaScript library that provides an output for data presented in HTML. The views of React are generally extracted through the deployment of “components.” These components can consist of additional components, which are specified in terms of custom HTML tags.

Go vs. C++ — main differences

When you start a new software development project, you have to consider which programming language or languages will meet all the technical requirements and offer the most suitable frameworks and libraries to succeed. Go and C++ both have their advantages and disadvantages, so choosing between them requires a fair deal of consideration. In this article, I’ll touch on topics such as which programming language works better for which projects, and what they are used for. But the main part of the comparison will focus on the speed and readability level of these languages, whether one of them is more secure, and how test code coverage and execution handling look in Go and C++.
