For example, there can be multiple JDKs, multiple versions of Ruby using RVM. For GoLang, there is a similar tool called GVM which can also be used to maintain multiple versio...

  API Design is UI for Developers

I’ve been thinking a lot about APIs and their design recently.I stumbled on this fantastic quote from Greg Parker: A programming language is a user interface for developers. Language authors should learn from HCI principles.22/02/2012 19:10 via webReplyRetweetFavorite@gparkerGreg ParkerWhen I first started learning C++ (back in the bad old days) I was convinced that any 1st year student could design a better programming language.

  No support of $.browser in jQuery 1.9

Starting from jQuery 1.9, $.browser is no longer supported to detect the nrpwser type and version. The substitute is $.support. In the newer jQuery 2.x versions, IE 6/7/8 are also not supported. If users want to support IE 6/7/8, they must use jQuery 1.9. If you want to fully support IE and want to use jQuery 1.9 and jQuery 2.0, the official solution is: <!--[if lt IE 9]> <script src='jquery-1.9.0.js'></script> <![endif]--> <!--[if gte IE 9]> <script src=...

  PHP to get access token for Facebook app

Since Facebook is now using OAuth 2.0 to authenticate apps to access user information. the SDK of Facebook has provided developers some useful functions to get authentication done. For example, in PHP SDK, there are getAccessToken(), getLoginUrl() etc. But unfortunately, for me I cannot use getAccessToken() method to get the user access token, it only returns me the app access token. Finally I gave up this approach to get access token for the time being. I may later retry this approach if I have...
