  The 9 lines of code of Google

Are you still remembering the then hot debated news about Oracle suing Google allegedly copying a small portion of codes from Oracle's Java in 2010. At that time, Oracle experts estimated that Google owes Oracle between $1.4 billion and $6 billion in damages if liable. But the court thought Oracle was eligible only for statutory damages for that copying, which were not expected to exceed a few hundred thousand dollars. At last, Oracle agreed the zero damage result. Are you curious about whi...

  Clojure & Java Interop

About a year ago I got a phone call asking if I wanted to join another team at DRW. The team supports a (primarily) Java application, but the performance requirements would also allow it to be written in a higher level language. I'd been writing Clojure (basically) full-time at that point - so my response was simple: I'd love to join, but I'm going to want to do future development using Clojure. A year later we still have plenty of Java, but the vast majority of the new code I add is Cloj...

  GO AHEAD, SELL MY DATA

More and more I see articles popping up that bash social networks for "violating" our privacy and selling our information to advertisers. Inevitably, Facebook has been at the center of many of these "scandals". Today on HN I came across this interviewwith Disconnect co-founder Casey Oppenheim and I just don't get it.In it, he bashes Facebook (and other online advertisers) for using our information in order to serve up targeted ads. He points out that many of the " “free” service...

  Windows Control panel mail icon

The exact location depends on your version of Windows and your layout settings of Control Panel. If your Control Panel is in the classic layout, you should see the Mail applet directly in the list of icons. For a 64-bit version of Windows Vista, the icon would be listed in the “View 32-bit Control Panel Items” section. If your Control Panel is in category view you can find the Mail applet in; Windows XP: User Accounts Windows Vista: User Accounts Windows Vista 64-bit: Additional O...

  Generate signed certificate from CSR in Java

In our previous tutorial, we have explained how to generate CSR which can be sent to CA for generating a signed certificate. In this tutorial, we will explain how to generate the signed certificate from CSR in Java. We will not use an actual CA but a self-signed certificate to act as a CA certificate. Since the CSR contains the subject information where a certificate needs to be generated and signed for. The key here is to extract the subject information from the CSR and then set it as the subje...

  A Hello, World Servlet

Servlets are the pure Java solution to handle web requests. Many application will use servlets instead of JSP and others will use servlets in conjunction with JSP. Experienced JSP programmers use servlets in conjunction with JSP to create clearer and simpler applications. The servlets handle Java processing: form handing, calculation and database queries. JSP formats the results. Servlets belong in WEB-INF/classes. On this machine, the source is in Java source in /var/www/hosts/www.caucho.com/we...

  Generate certificate in Java -- Store certificate in KeyStore

In previous post, we have explained how to create a certificate chain in Java. After generating the chain, we need to store it somewhere so that it can be used later when we are doing the actual SSL communication, either in a key store or trust store. This post will show you how to store the private key and its associated certificate chain in a keystore file. There are different types of keystore in Java, in this post, we will choose the JKS to demonstrate how to store the certificate chain. Whe...

  Android create button tutorial

This tutorial assumes that you already have an activity and are using an XML layout. Open the layout XML and add the button element.  Assign an ID with the “@+id” operator.  The + tells Android to generate an ID for this element so that you can reference it in your Java files. This is an example. Your layout and text elements will probably be very different. In this example case, the ID of the button is “close”. <Button android:id="@+id/close" android:lay...

  Arrays.equals() vs MessageDigest.isEqual()

Both Arrays.equals() and MessageDigest.isEqual() are used to compare the equality of two arrays. They can be interchangeably in many cases. However, they do have some differences which lead to different use cases in real applications. One difference is that the arrays passed to MessageDigest.isEqual() cannot be null while it's ok for Arrays.equals(). The one major difference between these two methods is that Arrays.equals() is not time-constant while MessageDigest.isEqual() is time-constant. Thi...
