Exerpt from bash documentation. HISTORY EXPANSION The bash shell supports a history expansion feature that is similar to the history expansion in csh. This feature is enabled by default for interactive shells, and can be disabled using the +H option to the set builtin command. Non-interactive shells do not perform history expansion by default. History expansions introduce words from the history list into the input stream, making it easy to repeat commands, insert the arguments to a previous command into the current input line, or fix errors in previous commands quickly. History expansion is performed immediately after a complete line is read, before the shell breaks it into words. It takes place in two parts. The first is to determine which line from the history...

The Android unit test framework is based on JUnit 3 , not JUnit 4. Test cases have to extend junit.framework.TestCase or a subclass (such as android.test.InstrumentationTestCase ). Tests are identified by public methods whose name starts with test , not methods annotated with @Test (as in JUnit 4). An Android test suite is packaged as an APK, just like the application being tested. To create a test package, first you need to identify the application package it is testing. Google suggests to put the test package source in a directory named tests/ alongside the src/ directory of the main application. At runtime, Android instrumentation loads both the test package and the application under test into the same process. Therefore, the tests can invoke methods on...

When you start Tomcat for the first time, you may get the "port 8080 is already in use" error. Indeed, port 8080 is commonly used by a lot of development servers by default (Oracle XE for another example). Luckily, it's quite easy to ask Tomcat to use a different port. I use port 8086, which is a natural next step and superior to 8080. Simply edit $CATALINA_BASE/conf/server.xml and change 8080 to 8086:
<!-- A "Connector" represents an endpoint by w...If you have not configured Tomcat 6 for multiple instances by setting a CATALINA_BASE directory, then $CATALINA_BASE will be set to the value of $CATALINA_HOME , the directory into which you have installed Tomcat 6.

On Linux, you can use the fuser command to find out who has a file open, or is using a port. For example, if you start Tomcat and get the error "Address already in use: 8080", you want to know which process is already binding to port 8080.
# list processes on port 8080 fuser 8080/tcp ...

When I tried to start Firefox 2, I got an error "libstdc++.so.5 not found". Looking under /usr/lib I found that I only have libstdc++.so.6, which came with FC4. Installing a "compat" package for libstdc++ solved the problem:
yum install compat-libstdc++-33.i386
