I got this error while compiling ucspi-tcp . The solution was to move #include <errno.h> from error.c to error.h .
The following also works:
echo gcc -O2 -include /usr/include/errno.h > conf-...
The reason was explained in http://cr.yp.to/docs/unixport.html#errno

You can use the system call from the os module to execute an external program:
>>> import os
>>> os.system(the_command_line_st...
However, the path to the executable contains a space character, the system call treats the strings after the first space as arguments, causing an error.
Python doc recommends the use of the subprocess module:
The subprocess module provides more powerful facilities for spawning new processes and retrieving their results; using that module is preferable to using this function.
For example, using wget to get the google home page:
>>> from subprocess import Popen, PIPE
>>> (out...

Suppose that I have an email field annotated with:
@NotEmpty(message="Please enter email address")
...
Bean validation will trigger two errors when no email address is entered:
the email field is empty
an empty email field is not a valid email address
Displaying both errors to the user with <form:errors> would be redundant and confusing:
<%@ taglib uri="http://www.springframework.org/tag...
This is how to display the first error only:
<spring:bind path="emailAddress">
<c:if test="$...

This example came from the jQuery validation documentation. The required rule can be used to validate a required selection box when you set the value of the first option to empty.

The error message is the title since no error message is specified. A more fully defined validation check would look like this:
$('#my-form').validate({

My problem is simple: in my XML data, a timestamp is provided as a long integer (number of milliseconds since the "the epoch"). When I do XSLT, I want to display it as a readable string, such as "Mon Nov 01 18:08:48 CDT 2010". After hours of struggle, I found: It's not so easy to get the job done with JDK 1.6 There are tons of garbage on the web in this space (suggestions, code snippets that simply don't work) Simple Xalan extension functions was the only resource that's somewhat informative. Even there some of the examples don't work. Below is a list of what worked and what didn't. This works:
<xsl:stylesheet version="1.0" xmlns:xsl="h... This does not (providing long value to Date constructor): <xsl:stylesheet version="1.0" xmlns:xsl="h......

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...

which can be easily dismissed as "input is invalid base64 encoded" or "partial input". But I know it's valid base64 encoded input!
The problem was, the input was base64 encoded on Windows! The error goes away after converting to Unix format with dos2unix .
