Few Simple Steps to Setup TWiki

TWiki is a Perl based structured Wiki application which can be used as team portal to share documents, presentations, blogs and many more within an organization. Thus it acts as a complete knowledge base. I did the setup for my team (on a Ubuntu Linux Server) and thought probably I should share the installation process, so that more and more people can easily get the benefit from this application-

Installation Steps-

  1. Install Apache Web Server: (httpd-2.2.15.tar.bz2)- http://httpd.apache.org/docs/2.0/install.html
  2. Make sure Perl (v5.10.0) is installed.
  3. Download Twiki- (TWiki-4.3.1.tgz)- http://sourceforge.net/projects/twiki/files/

Decompress using user account (not root), the uncompressed files automatically takes the access permission of the user account which uncompressed it. Place it inside of htdocs i.e. WEB_ROOT folder of Apache Installation e.g. for my setup I placed twiki inside of- /home/pprasanta/apache/htdocs/

  1. Configure TWiki, you can follow these tutorials

http://www.physics.carleton.ca/research/experimental/twiki/INSTALL.html

http://www.gentoo-wiki.info/HOWTO_TWiki

http://galeon.sourceforge.net/TWiki/TWikiInstallationGuide#StepTwo

  1. Give writable permission to “data”, “lib” and “working”. (chmod 777).
  2. Rename 2 existing sample configuration files- twiki_httpd_conf.txt to twiki_httpd.conf (in main folder of /twiki) and LocalLib.cfg.txt to LocalLib.cfg (you can find it in /twiki/bin)
  3. Define twiki lib path in LocalLib.cfg-

$twikiLibPath = "/home/pprasanta/apache/htdocs/twiki/lib";

  1. Update twiki_httpd.conf with the correct absolute (not relative) path of different twiki directories e.g. for my setup, lib path is /home/pprasanta/apache/htdocs/twiki/lib
  2. Update twiki_httpd.conf : Give access only to your IP address to access Configuration section i.e. /bin/configure. This is important as you don’t want unwanted person to change your configuration.

SetHandler cgi-script

Order Deny,Allow

Deny from all

Allow from 127.0.0.1 YOUR_IP

Require user JohnDoe

Satisfy Any

  1. Link the twiki_httpd.conf into http.conf

# TWiki

Include /home/pprasanta/apache/htdocs/twiki/twiki_httpd.conf

  1. Restart Apache and access the configuration page: http:///twiki/bin/configure
  2. When you are doing the configuration for the first time i.e. you are accessing- http:///twiki/bin/configure First time configuration will create- LocalSite.cfg which will store all configuration information of TWiki. /home/pprasanta/apache/htdocs/twiki/lib/LocalSite.cfg
  3. While configurations, for “Store Settings”, use RcsLite (this is the revision control system, which TWiki uses to manage document versions).
  4. If everything goes fine, start using TWiki- http:///twiki/bin/view
  5. IMPORTANT: You need to setup Email Notification setting with you SMTP HOST details. TWiki registration will not work without successful Email Notification setup.

Troubleshooting

  1. Configuration file /home/pprasanta/apache/htdocs/twiki/lib/LocalSite.cfg does not exist. For first time configuration, this error will come as there is no LocalSite.cfg file in your TWiki installation and it will create a new one. Make sure you have already followed step-4 i.e. already given access rights to mentioned directories.
  2. IMPORTANT: If you face problem like Can't locate Unicode/String.pm this means your PERL installation doesn’t have Unicode/String.pm file installed. Run following command as “Root” user to install Unicode/String.pm module- (Depending upon the user account permission, if you run the following command from any other user account doesn’t have sufficient permission, will result in failed String.pm setup)

# perl -MCPAN -e 'install Unicode::String'

Kindly Note:

I am not a TWiki Setup expert; I did this setup for my team and thought a small reference document might help others.

Android Parcelable Example

Few days back I had a requirement to send a ArrayList of my Custom Class Objects through Android Intent , I guess most of you also find this requirement now and then. I never thought it can be that tricky. There are built in functions in Intent to send ArrayList of primitive objects e.g. String, Integer, but when it comes to Custom Data Handling Objects, BOOM … you need to take that extra pain! Android has defined a new light weight IPC ( Inter Process Communication ) data structure called Parcel , where you can flatten your objects in byte stream, same as J2SDK’s Serialization concept. So let’s come back to my original requirement, I had a Data Handling class, which groups together a set of information- public class ParcelData {       int id;       String name;       String desc;       String[] cities = {"suwon", "delhi"}; } I want an ArrayList<ParcelData> of Data Handling objec...

Call Control in Android

This tutorial is for those who want to control Phone Call in Android OS. Programmatic approach to Accept or Reject call without user intervention. Kindly note, this approach uses Java Reflection to call methods of an internal class of Android Telephony Framework and might not work with all versions of Android OS. The core concept has been explained in this Android open code . 1st thing 1st, Give the permission . You need to define 3 User Permissions to handle call related functionality- android.permission.READ_PHONE_STATE android.permission.MODIFY_PHONE_STATE (For answerRingingCall() method) android.permission.CALL_PHONE (For endCall() method) Define a Receiver... Create a Receiver which accepts broadcasts with intent action android.intent.action.PHONE_STATE, define following in the Manifest- [receiver android:name=".PhoneCall"]         [intent-filter]             [action android:name="android.in...

Android Looper and Toast from WorkerThread

Have you ever tried to launch Android Toast message from worker thread? Probably you are wondering why the heck it is giving this error- java.lang.RuntimeException: Can't create handler inside thread that has not called Looper.prepare() In this article we are going to explore reason behind the above exception and try to understand how Looper works in Android. At the end, I am going to explain one approach to run Toast from a worker thread, but before that we need to understand how Looper works. If you already know in/out of Looper, you can skip below section and directly move to the solution part. Looper is a very basic wrapper class which attach a MessageQueue to a Thread and manage this queue. MessageQueue is a structure to sequentialize simultaneous processing requests of a Thread.  In Android, message/request processing classes like Handler uses Looper to manage their respective MessageQueue. Looper = Thread + MessageQueue Android Looper Life Cycle: As you can see in the abo...

Overlay on Android Layout

This will help you to create custom Layout and add Overlay on a LinearLayout. The concept can be reused on other Layout classes i.e. RelativeLayout, FrameLayout etc. I have added a popup Selection Palette, containing "Map Pin" and "List" icons. You can minimize the popup by clicking on the section in Green on the left side bottom corner of the screen.   How can I do that- You need to follow 4 steps- 1. Override LinearLayout Create a Class MyLinearLayout.java which should overwrite LinearLayout 2. Drawing You need to overwrite dispatchDraw (Canvas canvas) method. It gives control to the whole screen. Make sure you set android:layout_height="fill_parent" for the associated layout definition in XML. You can draw anything and anywhere on the canvas. dispatchDraw (Canvas canvas) gets called only after underlying views are drawn, so whatever you draw comes in the foreground.   3. Event Handling You need to overwrite dispatchTouchEvent (MotionEvent e...

Android Fragment

Fragment is being hanging out since Andriod 3.0, but with the release of 4.0, it has become an obvious choice for Android Application development for both Tabs and Smart phones. Few people think, fragment is a " Superman " which can add any kind of UI layout/style/decoration. But that is not true, rather than being an UI layout or decoration enhancer, Fragment is a very important concept to manage segments of your UI component code base . Prior to Fragment, developers were able manage UI flow only at the Activity level. All UI components were Views (mentioned in XML layout and part of Activity) and there was no way to manage these components separately. As a result all view management code were in a single file i.e. Activity class. With fragment approach, we can now remove View management code from Activity and place them in their respective Java classes. So, a pretty neat approach for code management. Here I'll explain various concepts of Fragment with an example appli...

HashMap Internal

I always wanted to implement the logic behind the famous data structure of Java , HashMap and here it comes. Though it’s not the complete implementation considering all optimization scenarios, but it will highlight the basic algorithm behind the HashMap . So let’s start, this implementation will use my LinkedList implementation (Reason: for this implementation I thought to write everything from the scratch apart from primitive data types. Sounds weird? May be ;-) ). You may refer my earlier post on LinkedList , as I’m going to use it. HashMap is a key-value pair data structure, where you retrieve value by passing key. To optimize the search of key, a concept of Bucket (an Array of Java Objects) has been introduced. This is used, so that if search hits this Bucket , corresponding value element is instantly retrieved, otherwise it iterates sequentially through the Linked List associated with each Bucket element. So you can say if all HashMap elements get fit into the Bucket, retrieving...

Accessing Yahoo Finance API

Since last few days I was wondering the right set of Web Service to read Country wise Stock Exchange index information . I found a bunch of scattered information, but no straight forward answer. It seems there are not many "reliable" and "flexible" options and Yahoo Finance is one of the top of this class. Though Yahoo Finance is very powerful, some how its very less documented and it seems Yahoo doesn't care much about this wonderful web service and expect Developers to do some kind of "hacking". The only online resource that I (and most of you as well ) found is one 3rd party web site- http://www.gummy-stuff.org/Yahoo-data.htm and it seems they know much more than what Yahoo dose..;-) Anyway let me continue and share my experience and information to help budding developer who wants to use Yahoo Finance Web Service in their Mobile, Web o r Desktop s olution. There are 2 set of APIs to access Yahoo Finance details- YQL based Web Service : Th...
