Crash Fix: mRemote 1.5 has stopped working

noreply@blogger.com (Unknown) — Tue, 23 Aug 2011 16:30:00 +0000

If you have ever used mRemote, it is a great utility for connecting to Remote System via SHH and Remote Desktop etc...

A few days ago i started seeing the message saying mRemote has stopped working and every time i start it, it would crash.... This is a fix...

mRemote saves data in 2 locations....

c:\Users\<user.name>\AppData\Local\Felix_Deimel
c:\Users\<user.name>\AppData\Roaming\Felix_Deimel

If you get the crash, I recommend the following

backing up your config file from C:\Users\<user.name>\AppData\Local\Felix_Deimel\mRemote\confCons.xml
Removing all the files in

c:\Users\<user.name>\AppData\Local\Felix_Deimel
c:\Users\<user.name>\AppData\Roaming\Felix_Deimel

Restore your config file
C:\Users\<user.name>\AppData\Local\Felix_Deimel\mRemote\confCons.xml

That should do it...

Enjoy

Java: #1 programming language in use today.

noreply@blogger.com (Unknown) — Mon, 02 May 2011 21:15:00 +0000

"Java continues to dominate the developer landscape as the No. 1 programming language in use today. It remains atop the TIOBE Index. According to Simply Hired, since April 2009, Java jobs increased 52 percent. With Oracle now the steward of Java and having shepherded two new Java Specifications Requests mapping out the next two versions of the language and platform—Java 7 and Java –the language is due for enhancements to "move Java forward," Oracle said. The language is used for a variety of things, including enterprise apps, as well as Web and mobile development."

Java: Ignore/Trust an invalid SSL cert for https communication

noreply@blogger.com (Unknown) — Sun, 03 Apr 2011 18:21:00 +0000

Very Once a while you will need your Java app to talk to a pre prod server (Web Service) over https, but you face the issue is that SSL is not a valid/expired/self signed cert...

You may get an error that looks like

You can add code to your app to ignore it or you can ask java to ignore that server's bad cert... The following is how i get java to ignore that invalid cert.

How to Ignore/Trust a Single Cert

WINDOWS
"%JAVA_HOME%\bin\keytool" -import -keystore "%JAVA_HOME%\jre\lib\security\cacerts" -alias abc-dev -file abc-dev.cer

MAC
sudo $JAVA_HOME/bin/keytool -import -keystore $JAVA_HOME/lib/security/cacerts -alias abc-dev -file abc-dev.cer

CentOS/Linux
sudo $JAVA_HOME/bin/keytool -import -keystore $JAVA_HOME/jre/lib/security/cacerts -alias abc-dev -file abc-dev.cer

How To Ignore/Trust a CA root certificate
--Note: there maybe multi files for a CA cert so do the following command for each file.

WINDOWS
"%JAVA_HOME%\bin\keytool" -import -trustcacerts -alias myCA -file myCA.cer.txt -keystore
"%JAVA_HOME%\jre\lib\security\cacerts"

MAC
sudo $JAVA_HOME/bin/keytool -import -trustcacerts -alias myCA -file myCA.cer.txt -keystore
$JAVA_HOME/lib/security/cacerts

CentOS/Linux
sudo $JAVA_HOME/bin/keytool -import -trustcacerts -alias myCA -file myCA.cer.txt -keystore
$JAVA_HOME/jre/lib/security/cacerts

Maven: version your maven-surefire-report plugin

noreply@blogger.com (Unknown) — Tue, 29 Mar 2011 20:42:00 +0000

If you get the following error while doing a deployment of the maven site... you may have a surefire plugin that is not version-ed.

The following is from the plugin's site

Note: As of version 2.8 this plugin requires Maven Site Plugin 2.1 or higher to work properly. Version 2.7.2 and older are still compatible with newer surefire versions, so mixing is possible.

I used the following to fix it

Official Google Voice Application Now Available in the App Store

Official Google Voice Application Now Available in the App Store: "

Maybe this really is a day we’ll never forget after all! Even though the Google Voice web app was pretty good, I always wondered why Google didn’t release an official app, especially since Apple loosened up its App Store approval process. It’s something I will never wonder again as Apple gave the green light today to the official Google Voice app.
