I never faced internet connection issues on ubuntu / linux, thanks to the Ndiswrapper / Additional driver of Ubuntu .
However some network hardwares like mine ( HP – Pavilion dv4 -1283cl ) require bit more work to bring up the internet connection.
1. First of all find the exact vendor name and model of your network hardware.
2. Search the vendor site to download the drivers for Linux incase exist else you need to manully build the wl.ko on your system and put it on the statup scripts.
X86 : Driver : https://docs.google.com/leaf?id=0B6gDoeCaurgfMWJjOWQ3OTktZDFiYS00NWM5LThiMzYtMzI5ZTlhNjY3MTE4&hl=en
X64 Driver : https://docs.google.com/leaf?id=0B6gDoeCaurgfYmVhMmMzYTUtMjMwOC00ZDBkLWFlNjgtNDhhNTgzZTQ2ZDVh&hl=en
For my laptop I’ve build the wl.ko file ( Ubuntu : 2.6.35-24-generic) :https://docs.google.com/leaf?id=0B6gDoeCaurgfMzVmY2RlMDMtZjA5NS00MTQxLThiMTQtMzhmY2EwOTJjYzkw&hl=en
s1. Download the Linux driver ( e.g for X86 OS : https://docs.google.com/leaf?id=0B6gDoeCaurgfMWJjOWQ3OTktZDFiYS00NWM5LThiMzYtMzI5ZTlhNjY3MTE4&hl=en )

Blogilo is an Amazing open source blog client for Ubuntu , the configuration to setup different blogging platform is really simple.
Just click Auto-Configure and Blogilo will pick the correct platform and API to post the blogs :
If you are running the application first time on Gnome , you might get an error like " Can not connect to database "
The program is not installing the sqllite automatically so just install the DB and it will work without any issues :
There are many tools / methods available to build a single jar having the dependent classes ( external libs) included on the single executable jar.
As far as I remember earlier only Borland’s JBuilder IDE was having this feature ( and .exe creation ) but now many open source api / ant scripts are available through which we can easily build a single jar file without any dependencies.
The best one is the Eclipse plugin : http://www.easyeclipse.org/site/plugins/fatjar.html
For Netbeans : http://arnoraps.tweakblogs.net/blog/4300/netbeans-single-jar.html
One Jar ( not so good) : http://one-jar.sourceforge.net/
HTTPClient from Apache is a nice API if you wanted to crawl the web through java.
I have used it in tasks like:
1. Automating some download.
2. Automation of form submit operation.
If you are behind the proxy server , make sure to add the proxy host and port on environment properties:
systemSettings.put("http.proxyHost", IP);
systemSettings.put("http.proxyPort", Port);
The use is quite easy for different http methods ( Get , Post..):
HttpPost httpost = new HttpPost("http://"+server+":"+port+propBaseURL+"?propertyName="+propertyName);
List nvps = new ArrayList();
nvps.add(new BasicNameValuePair("propertyName", propBaseURL));
nvps.add(new BasicNameValuePair("newValue", propNewValue));
nvps.add(new BasicNameValuePair("change", "Change Value"));
//http://strat-track.intranet.point/TrackingService.asmx/TrackingEnquiry
httpost.setEntity(new UrlEncodedFormEntity(nvps, HTTP.UTF_8));
HttpResponse response = httpclient.execute(httpost);
//entity = response.getEntity();
System.out.println("Login form get: " + response.getStatusLine());
import javax.servlet.annotation.InitParam;
import javax.servlet.annotation.WebServlet;
@WebServlet(
name = "HelloServlet",
urlPatterns = {"/hello"},
initParams = {
@InitParam(name = "param1", value = "value1"),
@InitParam(name = "param2", value = "value2")}
)
public class HelloServlet{
}Some most popular high performance http servers and SSJS based on C10K problem
1. NGinx
ginx is a free, open-source, high-performance HTTP server and reverse proxy, as well as an IMAP/POP3 proxy server
Nginx is known for its high performance, stability, rich feature set, simple configuration, and low resource consumption
Nginx powers several high-visibility sites, such as WordPress, Hulu, Github, Ohloh, SourceForge and TorrentReactor.
2. Tornado
Tornado is an open source version of the scalable, non-blocking web server and tools that power FriendFeed. The FriendFeed application is written using a web framework that looks a bit like web.py or Google’s webapp, but with additional tools and optimizations to take advantage of the underlying non-blocking infrastructure.
3. Node.js
Sample code which will generate a non blocking server :
An example of a web server written in Node which responds with “Hello World” for every request.
var http = require('http');
http.createServer(function (req, res) {
res.writeHead(200, {'Content-Type': 'text/plain'});
res.end('Hello World\n');
}).listen(8124, "127.0.0.1");
console.log('Server running at http://127.0.0.1:8124/');
To run the server, put the code into a file example.js and execute it with the node program:
% node example.js
Server running at http://127.0.0.1:8124/

syncnotes2google – Good tool to sync Lotus calendar with Google :
Tried it and its working like a charm …
Create a simple scheduled job / batch file for the tool :
batch file : LotusSyncGmail.bat
c:
cd “C:\soft\LNGoogleCalSync-1.6\LNGoogleCalSync”
set path=C:\IBM\Lotus\Notes;C:\Java\jdk1.6.0_21\bin;%path%
set classpath=%classpath%;lib/beansbinding-1.2.1.jar;lib/commons-codec-1.3.jar;lib/commons-httpclient-3.1.jar;lib/commons-logging-1.1.1.jar;lib/gdata-calendar-2.0.jar;lib/gdata-calendar-meta-2.0.jar;lib/gdata-client-1.0.jar;lib/gdata-core-1.0.jar;lib/jasypt-1.5.jar;lib/jdatepicker-1.1.0.jar;lib/jdom.jar;lib/Notes.jar;lib/swing-layout-1.0.4.jar;.
