Continuous Security Monitoring (CSM)
Learn what CSM is, how to implement it, and discover the most applicable use cases in this free white paper.
Given that you can't prevent all cyber attacks, you need to ensure you detect attacks as quickly as possible. The concept of continuous monitoring has been gaining momentum, driven by both compliance mandates (notably PCI-DSS) and the US Federal Government's guidance on Continuous Diagnostics and Mitigation, as a means to move beyond periodic assessment. This makes sense given the speed that cyber attacks can proliferate within your environment.
21 signs of BAD MANAGERS I met in my career as a software manager(by Ionel Condor) Bias against action or against planning, simply waiting or postponing for ever; embrace the status-quo, Secrecy, not willing to share information, giving the feeling that having access to information is a privilege reserved to managers, Working very long hours to prove hard work or hide incompetence...
Using serialization to find dirty fields in an object (by Raji Sankar) Say you are developing a framework to auto-save objects into a database. You need to detect changes made between two saves, so that only modified fields are saved. How to detect dirty fields. The easiest way to do this is to traverse through the original data and the current data and compare each field separately.
What Garbage Collector are you using? (by Nikita Salnikov Tarnovski) While dealing with the problems in this interesting domain, we thought to share some insights to GC algorithm usage. For this we conducted a study on how often a particular GC algorithm is being used. The results are somewhat surprising. Let me start with the background of the data – we had access to data from 84,936 sessions representing 2670 different environments to use in the study. 13% of the environments had explicitly specified a GC algorithm.
How to Optimize Your Website for Speed (by Mike Dalisay) Website speed becomes an obsession of search engines like Google and one of the reasons is the rapid growth of mobile internet browsing. If you're working with the web (developers, designers, bloggers and students), it is now a requirement to have knowledge in making a website load fast, and our post for today will give you some ideas on why and how to achieve it.
Android Content Provider Example A Content Provider is used to share and access data from a central repository. Usually android applications keep data hidden from the other applications but sometimes, it is useful to share data across them. So, content provider is a suitable reason to share data with other applications, based on a standard interface. There are many different ways to store data in a content provider but in most cases a SQLiteDatabase is used. In this tutorial, we are going to create our own content provider using SQLite database, in which we will store and handle our friends' birthday.
Create Web Application Project with Maven Example In this tutorial, we will show you an easy way to create a Java web application project, using Apache Maven. The web application will make use of the Spring MVC and it will be transformed, in order to be recognizable and supported by the Eclipse IDE. In this example, we use the following tools on a Windows 7 platform: Apache Maven 3.1.1, Eclipse Kepler Service Release 1, JDK 1.7, Spring 3.2.3.RELEASE, Apache Tomcat 7.
RESTEasy File Upload Example In this tutorial we are going to see how In this example we are going to see how you can upload a File to a server using a JAX-RS REST Service using RESTEasy. In this example we are going to use an HTML Form that has one input field of type file. When the HTTP POST request is constructed, it will contain a media type of multipart/form-data.
JUnit Using Assertions and Annotations Example In this example we are going to create test cases so as to understand the use of assertions and annotations in JUnit testing framework. Also, we will see how to run these test cases from the command line by using the org.junit.runner.JUnitCore. If you prefer running your test cases via Eclipse, you can have a look at JUnit Getting Started Example.

World of the NoSQL databases The relational database model focuses on the organization of the data in the form of two-dimensional tables. Each relational table is a two-dimensional array that has the following properties: each element of the table is a data element...
Why GitHub is not your CV Two days ago, Ashe Dryden published an article I've been desperately wishing someone would write for months: The Ethics of Unpaid Labor and the OSS Community. It's a detailed, well-researched take-down of the seemingly quite popular myth that open-source contributions are a useful way to screen candidates for software jobs.
Why Python Is The Most Powerful Programming Language For Web Applications Python is among the few programming languages that have become an essential component in Linux, MySQL, Perl, PHP, and Apache along with a packaged LAMP Web Stack. Ever since its inception, Python has grown along with other dynamic programming languages such as Ruby, to substitute the conventional programming languages such as C# and Java.
Hiring Software Developers I've been reflecting recently on my past few years working as a software developer. During those years I've had a lot of job interviews. I got many rejections, a few job offers and never heard back from some companies. This is a review, from my own perspective, of what works and what doesn't work when it comes to interviews and hiring processes for software developers.
The 10 rules of a Zen programmer On a rainy morning I found myself sitting on the desk thinking about efficient working. Before I started as a freelancer I had some days were I worked lots but could look only back on a worse outcome. I started with Zen practice back in 2006. What clearly came to my mind before a good while was: the old Zenmasters already knew before hundreds of years, how today programmers should work.
Java Annotations Tutorial with Custom Annotation Java Annotations provide information about the code and they have no direct effect on the code they annotate. In this tutorial, we will learn about Java annotations, how to write custom annotation, annotations usage and how to parse annotations using reflection. Annotations are introduced in Java 1.5 and now it's heavily used in Java frameworks like Hibernate, Jersey, Spring. Annotation is metadata about the program embedded in the program itself.
Getting rid of null parameters with a simple spring aspect What is the most hated and at the same time the most popular exception in the world? I bet it's the NullPointerException. NullPointerException can mean anything, from simple "ups, I didn't think that can be null" to hours and days of debugging of third-party libraries (try using Dozer for complicated transformations, I dare you).
