  Different types of keystore in Java -- JCEKS

JCEKS stands for Java Cryptography Extension KeyStore and it is an alternative keystore format for the Java platform. Storing keys in a KeyStore can be a measure to prevent your encryption keys from being exposed. Java KeyStores securely contain individual certificates and keys that can be referenced by an alias for use in a Java program. The process of storing and loading different entries in JCEKS is similar to what JKS does. So please refer to the article Different types of keystore in Java -...

  Let 's write some front end codes

I've seen a lot of arguments that there is no much technical value writing web portal, I think that the vast majority of good programmers will try many different things. The low level development and machine learning are not the only technologies which are  full of wisdom and challenges, I wrote web site for a few years, it is difficult to say that this is my initial interest, although I touched on other technologies as well, I still feel building website is challenging. Front end developme...

  JSON in JavaScript

When sending an AJAX request to the server, the response can have two formats : XMLHttpRequest.responseXML to access data with XML format and XMLHttpRequest.responseText to access data with string format. XML is the standard data transfer format, but one weakness is it's troublesome to parse and retrieve the data. JSON(JavaScript Object Notation) is a light weight data interchange format, we call it the JavaScript object representation. The advantage of using JSON as the data format is itself is...

  Canonicalize XML in Java

XML canonicalization is often used when there is need to create digital signature to be sent to peers for verification. Since digital signature is created based on XML data, the XML data has to be canonicalized before its signature value can be calculated. Even an extra space may affect the signature value calculated, hence it must follow some rules to canonicalize the XML data so that it has a standard format. This is why W3C created specification Canonical XML Version 1.1. This specificat...

  Disgusting programming language list

To avoid arguments among different programming languages, this ranking only covers the opinions from programmers with multi-language experience. Also it doesn't mean the language is not good if the language is on the list, it just means those developers don't like some features of the language. Below ranking is summarized from Quora、Stack Overflow and Hacker News. 10. Python Reason : It uses code indent to define block level scope, why not use curly braces? It also uses massive colons and ...

  Why PHP is (so much) better than Ruby?

I attended this weekend my first Ruby conference, Ruby Lugdunum in Lyon. Besides cool talks and the fun of meeting people like Nick, Blake, or Laetitia, my friend Camille & I did a surprise lightning talk about how PHP is better than Ruby. Here are the slides and a more detailed transcript: A lot of free hosts: it’s easy to find a PHP host, you just have to google “free php host” and you find a ton of free PHP/MySQL hostsBigger community: The PHP community is really huge,...

  Ajax file upload tutorial

Step 1 - AJAX file uploadAJAX file upload tutorialFirst of all I have to say that to create a pure AJAX file upload system is not possible because of security limitations of JavaScript. All of the Ajax upload systems I know use some third party tool/package or only mimics the AJAX feeling. Even so it makes file upload process a bit nicer. In the next section I will present you a solution which imitates the AJAX process, but uses a normal upload process and iFrames.The concept: Create a simp...

  What drives the popularity of Node.js?

JavaScript is a programming language which can be used on both front end and back end. Its popularity should mainly be attributed to its power in front end side. While people seem not realize its power in back end until the appearance of Node.js.  Node.js is a server-side software system designed for writing scalable Internet applications, notably web servers. Programs are written on the server side in JavaScript, using event-driven, asynchronous...

  I am a great programmer, but horrible algorithmist

I am a great programmer, but a horrible algorithmist. It is a thought that has been weighing on me heavily recently, and I'd like to gather other developers feelings on the subject as well. I started what can be called my professional development career back in 1999. I was still in middle school, but my father hired me at his software company. My official duty was to make updates to our websites, but I mostly ended up bugging the other developers to help me learn. From there I picked up ...
