  Learn from Haskell - Functional, Reusable JavaScript


Learn You a Haskell: For Great Good? For the last couple months I have been learning Haskell. Because there are so many unfamiliar concepts, it feels like learning to program all over again. At i.TV, we write a lot of JavaScript (node.js and front end). While many functional/haskell paradigms don’t translate, there are a few techniques that JS can benefit from. There are Haskell library functions for everything. At first I thought this was just because it was mature, but then I noticed tha...

  Different types of keystore in Java -- DKS


Domain KeyStore(DKS) is a keystore of keystore. It abstracts a collection of keystores that are presented as a single logical keystore. Itself is actually not a keystore. This new keystore type is introduced in Java 8. There is a new class DomainLoadStoreParameter which closely relates to DKS. To load different keystores into the single logical keystore, some configuration is needed. Here is the format of the configuration for grouping different keystores. domain [ ...] { keystore [ ....

  How does Base64 work


Base64 is a data encoding scheme used in safe data transfer such as HTTP and its extensions. Base64 encoding can conver arbitrary group of bytes into a sequence of readable ASCII characters. These converted characters can safely put in a HTTP header without causing any problem while the peers process the HTTP header. Base64 encoding was invented as part of the MIME content transfer encoding. It is similar to other encoding schemes such as Uuencode and BinHex but with higher efficiency....

  noConflict mechanism in jQuery


Many JavaScript frameworks like to use $ as function or variable name, jQuery is one of them. In jQuery, $ is just a reference to window.jQuery, so even if $ is deleted, window.jQuery will still be available to ensure the whole library can work normally. jQuery API design takes fully consideration of multiple frameworks conflicts, we can use jQuery.noConflict function to easily handle control. jQuery.noConflict accepts one optional boolean parameter[1] to determine whether to hand jQuery object ...

Today, Elliotte Rusty Harold posted his doubts about the merits of closures in Java. Specifically, he asks "Why Hate the for Loop?": I don’t know what it is some people have against for loops that they’re so eager to get rid o...

  30-Minute Exercise to Become a Better Programmer


I believe that motivation is really important. That’s why from time to time I read books about time management (as they motivate me to be focused and continue evolve my TM-system) and books about software craftsmanship. The other day I finished one of this kind of books - “Apprenticeship Patterns: Guidance for the Aspiring Software Craftsman”. This book motivated me to think carefully what I want to invest my time in. Also, it coincided with my 25th birthday and, of course, the new...
