According to MSDN : On Windows 7 and on Windows Server 2008 R2 with the Wireless LAN Service installed, the operating system installs a virtual device if a Hosted Network capable wireless adapter is present on the machine. This virtual device normally shows up in the "Network Connections Folder" as "Wireless Network Connection 2" with a Device Name of "Microsoft Virtual WiFi Miniport adapter" if the computer has a single wireless network adapter. This virtual device is used exclusively for performing software access point (SoftAP) connections. The lifetime of this virtual device is tied to the physical wireless adapter. If the physical wireless adapter is disabled, this virtual device will be removed as well. On Windows 7, there's no UI to start or stop SoftAP....

Oracle sqlplus command line tools does not support command line editing out-of-the-box. But on Linux there's a handy utility that enables command line editing with any command line tool: rlwrap - readline wrapper.
Install rlwrap:
$ sudo apt-get install rlwrap
Create a keywords file .sql.dict (optional, but convenient):
false null true

It would be nice to add the tables names also.
Create an alias for sqlplus (put it in .bashrc ):
alias sqlplus='rlwrap -f $HOME/.sql.dict sqlplus'

The MIPS CPU is able to run both big-endian and little-endian. So a system built on MIPS can be either big-endian (mips) or little-endian (mipsel).
The file command shows the architecture:
$ file ls
ls: ELF 32-bit LSB executable, MIPS, ...
but readelf will tell the endianness:
$ readelf -h ls
ELF Header:

Step 1: Repackage a web app as EAR A Java EE application is a multimodule Maven project. At the very least you'll need to package a WAR and an EAR. To get started, I'll simply re-package the simple webapp as an EAR. Create a directory named javaee-app Copy the webapp from here to javaee-app . Rename struts1app to webapp . Create pom.xml under javaee-app :
<project> <modelVersion>4.0.0</modelVersion>... Create a directory named ear under javaee-app . Create pom.xml under ear : <project> <modelVersion>4.0.0</modelVersion>... Modify pom.xml in the webapp directory so that it looks like this: <project> <modelVersion>4.0.0</modelVersion> ... Build with " mvn package " in the javaee-app directory. You can see that ear-1.0.ear is successfully generated in javaee-app/ear/target . Maven successfully resolves dependencies between the sub-projects....

Facelet templates can be nested, for example, a page can use a template which inherits from another template. To demonstrate this, let's start from the simple example and make these additions:
Add a place holder for CSS style sheets in WEB-INF/templates/default.xhtml :
<h:head>
<title>Facelets Template Demo</tit...
Add a derivative template ( WEB-INF/templates/default-style.xhtml ) which provides CSS:
<?xml version="1.0" encoding="UTF-8"?>
<ui:comp...
Add a page that uses the styled template ( home-style.xhtml ):
<?xml version="1.0" encoding="UTF-8"?>
<ui:comp...
The only difference between this file and home.xhtml is the template being used.
Compare the display of the pages home.xhtml and home-style.xhtml .

After an IPSec connection is established, all traffic between the network interfaces named in /etc/ipsec.conf are tunneled through IPSec. And only the protocols and ports listed in /etc/ipsec.conf are allowed. For example, if you were able to ssh to the server, after IPSec connection ssh is no longer working if port 22 is not listed. Assume that you set up IPSec tunnel between the hosts 192.168.0.1 and 192.168.0.101 , these tests will show that the IPSec connection is successfully working. Before bringing up IPSec connection If IPSec connection is already established, bring it down:
# ipsec auto --down TCP8080-PSK-CLIENT Monitor server port 8080 with tcpdump ( 192.168.0.1 ): # tcpdump -i eth0 port 8080 -X On server side ( 192.168.0.1 ), listen on port 8080:...

These steps set up a Linux host as IPSec client, using Openswan .
Install Openswan:
# yum install openswan
Edit /etc/ipsec.conf . Instead of L2TP on port 1701, I'm setting up TCP on port 8080 so that I can test the connection with nc .
# /etc/ipsec.conf - Openswan IPsec configuration f...
Edit /etc/ipsec.secrets .
# include /etc/ipsec.d/*.secrets

# ipsec auto --up TCP8080-PSK-CLIENT

When you run automated Android tests with Eclipse or from the command line, you get text output, which isn't good for reporting purposes. If you run a large set of test cases with automated build, the text report isn't very helpful. Fortunately, Android CTS generates test reports in XML with accompanying XSL to make it look nice in a browser. To run your own tests with Android CTS: Download Android CTS Make a new directory MyRepository under android-cts , alongside the existing repository directory. Copy host_config.xml from repository to MyRepository Create directory plans under MyRepository , add a test plan ( MyTests.xml ):
<?xml version="1.0" encoding="UTF-8"?> <TestPla... Create directory testcases under MyRepository . Copy TestDeviceSetup.apk from repository/testcases to MyRepository/testcases Under MyRepository/testcases , create a test...

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...
