Google prOgramming language - GO

Google had released a new programming language named GO.
Their one goal behind this is to increase the developer productivity and efficiency by giving them a faster compiler.
As Google says this is even capable to be used in developing system software and it is powerful than C but not than C++.

STSADM

STSADM is a command line tool which we can use to perform administrative tasks on SharePoint Server, this is very powerful since it provides features that are not available in the Central Administration site.
You will be able to find this executable at,
%COMMONPROGRAMFILES%\microsoft shared\web server extensions\12\
For example - C:\Program Files\Common Files\Microsoft Shared\web server extensions\12\BIN


To learn more visit the following TechNet link.
http://technet.microsoft.com/en-us/library/cc261956.aspx
Following link will have the list of operations and properties.

STSADM Error

Recently I faced a curios error while using the STSADM.exe command line tool.
If anyone of you are not knowing wht STSADM is please refer my earlier post with links to get more information.
However powerful STSADM is, while using it suddenly Windows might tell you that STSADM is not a valid Win32 application.
If you check the file you will also notice that the Windows icon of that exe is disappeared and also the file size is 0.
The good thing is that you will be able to get the file from another SharePoint installation and replace, then everything will start working normally.

WSUS

Recently I had to install and configure WSUS (Windows Server Update Services) on our company.
I feel this is a very handy way to distribute the software updates through out the company.
In configuring it the following articles was helpful to me so thought to share them with you.
This is the main Microsoft site for WSUS,
This is the main TechNet site for WSUS,
Following pages show how to configure clients,

Editing NTFS Drive Contents on Mac OS

In Mac OS if you mount a disk formatted in NTFS file system, you will be able to view the contents and even to copy contents from that disk (Read) but you will not be able to save, delete or paste (Edit) anything.
To enable editing in the disk you will be needing to install the NTFS driver.
If you are searching for a driver, download NTFS-3G Stable Read/Write Driver from NTFS-3G.

Distributing BlackBerry Applications Over Internet

BlackBerry applications that you develop can be distributed over the internet quite easily when you know what you need to do. In this method users need to browse to the web URL and click on it so the BlackBerry will download and install the file automatically.

Step 1 - Prepare the Files
When you compile the source code of the application you will be getting a .cod file.
Check the file size of it, if the cod file is less than 55KBs then you can use it without doing anything more.
If that is larger than you need to do the following trick to make the application distributable over the internet.
  • Change the extension of the cod file to zip.
  • Unzip the zip file.

You will now see a set of cod files with names like App-1.cod, App-2.cod, App-3.cod, etc.

Step 2 - Prepare the Server
To make BlackBerry devices correctly identify and download the files you need to add or update the Multipurpose Internet Mail Extension (MIME) types in your web server. The required MIME types are as follows.
File Name Extension - MIME Type
cod - application/vnd.rim.cod
jad - text/vnd.sun.j2me.app-descriptor
jar - application/java-archive

If you need more details on how to set MIME types in different web servers please contact me, I will try to provide you with more details.

Now place the cod files we prepared in Step1 in the server.

BlackBerry Network Diagnostic Tool

Latest BlackBerry smart phones are supporting many different network transports to enable reliable data communication between third-party applications and the Internet.

BlackBerry have provided a good tool named "Network Diagnostic Tool" which is essentially a role model that answers all these questions and is a functional diagnostic tool for testing a URL over various transports supported by the BlackBerry solutions, as well as for displaying the values of many network attributes during the test period.
You will be able to download it freely from BlackBerry knowledge base.
If you need to know more about the available transports and more in depth details on the network diagnostic tool, better visit the Article Number: DB-00684 at the BlackBerry knowledge base.

Setting APN Automatically

If you tried to create a BlackBerry application which uses internet through Direct TCP transport and needed to release it to a set of users who are using different mobile networks you may have had the problem of how you can release the application in a way that users don't have to make any setting changes to make your application get connected. The complexity here happens because different service providers (mobile networks) are using different settings (for example APN).
After some searching on the net I found one way to achieve this is by identifying the mobile network and then setting the connection properties appropriately.
The steps involved is as follows.

Step 1
Identify the network the phone is currently in.
If you need help on this go to this URL.

Step 2
Get the APN settings for your network.
The way here is to have a file with all the settings of different wireless service providers you intend to run your application on, and then compare the value returned from Step 1 and get to the particular APN.
I suggest you to keep a XML or text file with the following details of the service provider,
  • Country Name
  • MCC
  • Carrier Name
  • MNC
  • TCPAPN
  • TCPAPNUserName
  • TCPAPNPassword
  • WAPAPN
  • WAPIP
  • WAPPort
  • WAPUserName
  • WAPPassword
  • WAPSourceIP
  • WAPSourcePort
  • IsEnableWTLS
Step 3
Add the APN to the connection.
If you need help on this go to this URL.

Determining the Network

In the BlackBerry project that I am in now we are having the requirement to detect the mobile network the phone is currently in.
Basically in BlackBerry mobile network is uniquely identified by the Mobile Country Code (MCC) and the Mobile Network Code (MNC).
To get these details from your code what you have to do is to call

RadioInfo.getMCC()
and
RadioInfo.getMNC()

These will return the codes in decimal.
You can find a full list of MNC codes of the mobile phone operators and a list of country codes by following the following URLSs to Wikipedia.
http://en.wikipedia.org/wiki/Mobile_Network_Code
http://en.wikipedia.org/wiki/Mobile_Country_Code

If you need to access the BlackBerry knowledge base article describing the above process you can follow the following link.

Setting APN

APN or Access Point Name is a setting which needs to be set on the mobile when we need to get connected to internet using the phone.

APN changes from one mobile service provider to the other. For example Dialog will have http://www.dialogsl.com/ Rogers will have internet.com set as their APN.

But letting users set the APN manually is always not the preferred way. Recently we developed an application for BlackBerry which the user needed to get to the internet without he manually setting the APN. The application was supposed to be delivered through BlackBerry App World so manually setting APN was not an option. In a case like this what you have to do is set the APN programmatically into the connection.

String URL = “www.SomeServer.com”;
StringBuffer bfURL;
bfURL = new StringBuffer ();
bfURL.append (URL);
bfURL.append ("
;deviceside=true ;apn=internet.com");
bfURL.append ("
;tunnelauthusername=UserName;tunnelauthpassword=Password");
String FinalURL = bfURL.toString ();

In the above code I have set the Rogers APN in to this connection.

If you need more details on the parameters used or need to know about the other parameters you are eligible to use such as WapGatewayIP, WapGatewayPort, WapGatewayAPN, etc visit the following link to view full details of the connector class.
