Introduction Whether you're new to deep learning or a serious researcher, you've surely encountered the term convolutional neural networks (CNNs). They are one of the most researched and top-performing architectures in the field. That being said, CNNs have a few drawbacks in recognizing features of input data when they are in different orientations. To address […]
Mastering lambdas in Java is one of the most powerful and frequently used skills in modern Java development — lambdas (introduced in Java 8) allow you to write concise, expressive, functional-style code that replaces verbose anonymous classes, making streams, collections processing, event handling, multithreading, and APIs like forEach, map, filter, and sort much cleaner and more readable. In 2025–2026, lambdas are everywhere in real-world Java: Spring Boot, Android, reactive programming (Project Reactor), parallel streams, and almost every modern Java library.

Introduction FreeBSD 12 is a UNIX-derived operating system renowned for its network stack performance, ZFS integration, and Jail isolation primitives. Setting up configure zfs pool management on freebsd 12 on FreeBSD 12 follows the rc.conf/service(8) paradigm rather than systemd, which means enabling a service and configuring its startup options are done differently from any Linux […]
In this tutorial you’ll learn how Suricata signatures are structured, and some important options that are commonly used in most rules. Once you are familiar with how to understand the structure and fields in a signature, you’ll be able to write your own signatures that you can combine with a firewall to alert you about most suspicious traffic to your servers, without needing to use other external rulesets.

Secured Socket Layer (SSL) is the cryptography protocol to provide message security over the internet. It works on the notion of Private and Public keys and messages are encrypted before sending it over the network. To configure SSL on Tomcat, we need a digital certificate that can be created using Java keytool for development environment. For production environment, you should get the digital certificate from SSL certificate providers, for example, Verisign or Entrust.
