Ubuntu: Proxy settings for Maven

Recently I faced problem using maven under a proxy network and by little research, found this solution.
Temporary solution:
Add the following options along with your maven command

-DproxySet=true -DproxyHost=myproxy.com -DproxyPort=3128

For example, to run "mvn package":

mvn -DproxySet=true -DproxyHost=my.proxy.host -DproxyPort=3128 package

Permanent solution:
To add the proxy settings permanently, goto {M2_HOME}/conf/settings.xml and find the <proxies> section. Un-comment the required sections and configure accordingly.
To set proxy without password protection, change it as follows:

<proxies>
   <proxy>
      <id>optional</id>
      <active>true</active>
      <protocol>http</protocol>
      <host>proxy.host.net</host>
      <port>80</port>
      <nonProxyHosts>local.net|some.host.com</nonProxyHosts>
    </proxy>
</proxies>

Change the words in italic format.

Find an old archived link on web

In recent past, I'm need of a tool, to which the provider no longer provides the link to download. Previously I've blogged about Openlogic , which serves this purpose. Openlogic contains unofficial fork of the original repository, and to be precise, I haven't found the tool I'm in search of. I found Internet Archive : Wayback Machine , while searching for it. It has got 412 billion stored pages and you may look into older versions of any website or you can get link to any software/tool which used to be a website. All you have to do is, provide a link or part of a link to search. For example, to know how my website used to be in 2013, just type http://www.thechaithanya.com and you can see a calender with some of the dates highlighted, on which they had the snapshot of my website. You can even provide a part of link. For example, to get the link of older version of Android ADT, search using http://dl.google.com/android/adt/* You can find a set of links and...

Setting JVM Heap size at runtime

To set the JVM heap size, compile the program normally. For example, consider Runtime.java program. Compilation: javac Runtime.java Now, to set minimum heap size(let, 16 MB) required by JVM, run the program as follows : java -Xms16m Runtime We can also restrict maximum size(let 512 MB) utilized by JVM: java -Xmx512m Runtime Both these options can also be combined to specify upper and lower bounds of JVM heap size: java -Xms16m -Xmx512m Runtime Now you can run a program that requires huge computational space.
