TIP:Lenovo Thinkpad W520 Fedora 16 Internal Mic Not Working

2012-02-09T15:42:00.000-08:00

Solution as mentioned in
https://bugzilla.redhat.com/show_bug.cgi?id=752610 is

$ sudo vi /etc/modprobe.d/dist-alsa.conf

Add as the first line.
options snd-hda-intel index=0 model=thinkpad

Then reboot and you should be good to go.

If you are keen on seeing what my file looks like:

# ALSA Sound Support
#
# We want to ensure that snd-seq is always loaded for those who want to use
# the sequencer interface, but we can't do this automatically through udev # at the moment...so we have this rule (just for the moment).
#
# Remove the following line if you don't want the sequencer.

options snd-hda-intel index=0 model=thinkpad

install snd-pcm /sbin/modprobe --ignore-install snd-pcm && /sbin/modprobe snd-seq

TIP: Passphraseless SSH on Fedora

2012-01-25T20:42:00.001-08:00

If you are trying to set up passphraseless SSH on Fedora, then remember that the permissions on the file authorized_keys should be 644 ====================================================== .ssh$ chmod 644 authorized_keys anil@sadbhav:~/.ssh$ ssh localhost Last login: Sun Jan 22 21:42:06 2012 from localhost anil@sadbhav:~$ exit logout Connection to localhost closed. anil@sadbhav:~/.ssh$ chmod 644 known_hosts ================

Disk Cleanup : Linux Distribution

2011-06-01T10:52:00.000-07:00

Lets assume that you are looking for TreeSize alternative in the Linux world. There are a few disk usage/cleanup tools available under GNome or KDE.

If you have some time, then cleaning up your home directory is pretty simple on the command line:

Assume you want to clean your /home directory.

$> du -H /home > cleanfile

Now when you open cleanfile in your text editor, you should see the files/directories. Looking at the directory names should tell you whether you need those dirs or now.

Scheduler Jobs in JBoss AS

2011-05-18T10:58:00.000-07:00

If you are interested in scheduling tasks in JBoss AS, there are few pointers that you should look at and choose:

1) Quartz Scheduler
The EJB3 subsystem has quartz integration that you may want to utilize.

http://docs.jboss.org/ejb3/docs/tutorial/1.0.7/html/Quartz_scheduler_integration.html

http://community.jboss.org/wiki/HowtoconfigureaQuartzservice

Reference: http://www.quartz-scheduler.org/

2) Use java.util.Timer
You will need to create your own instances of timer tasks in your application.

3) JBoss Scheduler

http://docs.jboss.org/jbossas/docs/Server_Configuration_Guide/4/html/Additional_Services-
Scheduling_Tasks.html

Section 10.7 and 10.8 of http://docs.jboss.org/jbossas/docs/Server_Configuration_Guide/4/html/index.html

org.jboss.ws.core.jaxws.handler.SOAPMessageContextJAXWS

2011-04-06T07:29:00.000-07:00

If you see the following exception:
javax.xml.ws.soap.SOAPFaultException: org.jboss.ws.core.jaxws.handler.SOAPMessageContextJAXWS cannot be cast to javax.xml.rpc.handler.soap.SOAPMessageContext

it means that in your handler class, you are using javax.xml.rpc.handler.soap.SOAPMessageContext
rather than
import javax.xml.ws.handler.soap.SOAPMessageContext

Tip::Pidgin and MSN connection issues

2010-12-02T10:25:00.000-08:00

Typically you have errors such as :
The certificate for omega.contacts.msn.com could not be validated. The certificate chain is invalid.

Solution:

Assuming you are on Linux.

1) Delete the MSN related certificates.
==============
anil@localhost:~$ cd .purple/certificates/x509/tls_peers
anil@localhost:~/.purple/certificates/x509/tls_peers$ ls
api.oscar.aol.com contacts.msn.com login.live.com ows.messenger.msn.com
api.screenname.aol.com gmail.com login.yahoo.com rsi.hotmail.com
bos.oscar.aol.com omega.contacts.msn.com
anil@localhost:~/.purple/certificates/x509/tls_peers$ rm *live*
anil@localhost:~/.purple/certificates/x509/tls_peers$ rm *msn*
anil@localhost:~/.purple/certificates/x509/tls_peers$ rm rsi.hotmail.com
anil@localhost:~/.purple/certificates/x509/tls_peers$ rm login.live.com
================

2) In that particular directory, do a "wget"
$> wget http://bit.ly/dbLSzq -O omega.contacts.msn.com

3) In Pidgin, Accounts -> xxx.msn.com -> Disable Account
or Accounts -> xxx.hotmail.com ->Disable Account

4) Now enable the account in "Accounts"

Android Dev Tips

2010-07-12T21:46:00.000-07:00

Tip 1: Import a sqlite DB from somewhere else (let us say db.sqlite)
tools$ ./adb push ~/android/db.sqlite /data/data/test.app/databases
1934 KB/s (443392 bytes in 0.223s)

Tip2:
While Activity.setContentView takes an id of a Layout, TabSpec.setContent takes an id of a View.

Tip 3: Android: Get the Application Version in an activity
PackageInfo info = getPackageManager().getPackageInfo( getPackageName(), 0 );
String version = info.versionName;

Tip 4: Android onNewIntent() is never called.

In the android manifest file for the activity, add the following attribute
android:launchMode="singleInstance"

KNetworkManager and VPN

2010-07-06T08:28:00.000-07:00

Since Fedora 13, I have been unable to use the nm-applet on KDE. It seems like KNetworkManager is the default in KDE on Fedora 13.

Try to get the knetworkmanager-openvpn and knetworkmanager-vpnc packages installed on your fedora instance.

$> sudo yum install knetworkmanager-openvpn
$> sudo yum install knetworkmanager-vpnc

The nm-applet settings for vpn are all lost. So you will need to login to gnome to get those settings and input them into knetworkmanager.

But there are some pending bugs because the knetworkmanager vpn is not really working for me (and also a co-worker). Keeping fingers crossed to see if a future update will fix it.

Mobile Development Tips: Blackberry Application Development

iphone4 antenna issues

2010-06-28T18:47:00.000-07:00

Now that Apple has released iphone4, there are growing complaints from users about the Antenna.

Based on this story, Apple acknowledges the antenna issues.

Apple has responded with a statement:

"Gripping any mobile phone will result in some attenuation of its antenna performance, with certain places being worse than others depending on the placement of the antennas. This is a fact of life for every wireless phone. If you ever experience this on your iPhone 4, avoid gripping it in the lower left corner in a way that covers both sides of the black strip in the metal band, or simply use one of many available cases."

To mitigate this problem, it is best to get one of the cases for the phone. Not only with a case do you guard the phones from drops, but also the reception issue is solved.

Echo Framework - Java RIA Framework

2010-05-19T09:33:00.000-07:00

Contributed by Echo Framework expert Rakesh Vidhyadharan:

The Echo web application development framework is often referred to as
"the best kept secret" among the developers who are familiar with it.
Echo attempts to present a AWT/Swing type programming interface to
develop web applications. Echo and Zk seem to have been the earliest
proponents of this philosophy, which has since been adopted by GWT, Wicket
etc.

The current version of Echo is Echo3, which represents a more modern and
radical change from Echo2. Echo2 had been primarily a server rendering
system, that generated the entire HTML rsponse on the server. Echo3 on
the other hand delegates the rendering to a new Client Engine JS service
that is loaded by the browser when an application is first loaded. The
server still maintains the current state (the components currently displayed
on screen, and their respective state). During a client-server
interaction the server sends XML messages that indicate any rerendering
as well as the data necessary to display in the client components.

Echo API is now split into a pure client-side API that usually has a 1-1
mapping to their server side component API. With Echo3 it is now possible
to write a pure JS only rich web application, that uses traditional AJAX
XmlHttpRequest wrappers to interact with any web service. In fact the
server side components are rendered using these same client components
when the application is built using Java.

The Echo3 demo application (http://demo.nextapp.com/echo3csjs), as well as
the EchoPoint client test application (http://sptci.com/echopointclienttest/)
are examples of applications created purely using the Echo3 client-side API.

Unlike GWT, any language that runs within the JVM may be used to build
server-side Echo applications. Groovy and Scala in particular have been
used by regular Echo3 users to build rich internet applications. Similarly,
it is possible to use reflection and other dynamic features to reduce the
amount of boiler plate code that needs to be written to create a server-side
application.

Eclipse 3.5 (Ganymede) update issues

2010-04-25T20:33:00.000-07:00

Solution 1: As described in the eclipse wiki link, please remove the mylyn update.

Solution 2: This may work

Problem: Eclipse 3.5 software update does not work. You see errors such as "No repository information found".

Steps:

1) Help -> Install New Software -> Available Software Sites

2) Select all and then export it as bookmarks.xml

3) Now remove all the urls from the dialog box.

4) In a text editor of your choice, go into bookmarks.xml and add a "/" at the end of all the urls.

5) Now in the eclipse dialog, import this "bookmarks.xml".

6) Enable all the urls. (You need to click on the Enable button while having all the sites selected).

That's it. Now you will be able to get away from the errors.

Caveat: Every time you add in a new software site to update/install, remember to add in a "/" at the end of the url.

Step 2: Now go into JMeter GUI and import this test plan "formAuth.jmx"

Description:
* In this example, the web app is HelloJBoss.
* First we access the web application to establish the cookies etc.
* The initial servlet we are using is HelloJBossServlet after form auth.
* Once we are done with form auth, we do the log out.

Filing US Tax Returns for Free

2010-04-04T10:04:00.000-07:00

Millions of American Residents, come March/April, look for ways to file their US Tax returns. The deadline as always in April 15th of each year for the previous calendar year.

This is how I do it:
* Federal Returns: I download the free desktop edition of Tax Act. Go to www.taxact.com to get it. This desktop version then allows you to e-file federal return for free.
* State Returns: My state, Illinois allows me free e-File. So I just do it from the IL Department of Revenue website. I am positive that many states of the US allow you to file tax returns.

Happy Stress Free Tax Return Filing.
