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

In this example I'll add a parameter to a facelets template. The example contains three tabs, each tab points to a different page. The tab control is shared among all pages, therefore, it is put in the template.
Starting from the simple facelet example , make these additions:
Create a new template WEB-INF/templates/tabs.xhtml :
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Stric...
Add a page for the about tab ( about.xhtml ):
<?xml version="1.0" encoding="UTF-8"?>
<ui:comp...
Add a page for the news tab ( news.xhtml ):
<?xml version="1.0" encoding="UTF-8"?>
<ui:comp...
Add a page for the partner tab ( partner.xhtml ):
<?xml version="1.0" encoding="UTF-8"?>
<ui:comp...
Build and re-deploy the application. Launch the browser and load page http://localhost:8080/facelet-demo/about.jsf .

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 .

A naive try would be something like this:
$ nc -l 8082 | nc remote_host 80 Yes, it does forward the request from local port 8082 to remote_host:80 , but the response is dumped to stdout , not routed back to the client as expected. Using a named pipe makes it work: $ mkfifo backpipe $ nc -l 8082 0<backpipe | nc ... Use tee to get a glimpse of the response through the pipe (I wasn't able to find a way to dump the request): $ nc -k -l 8082 0<backpipe | nc localhost 80 | tee... The GNU netcat has a different syntax than the stock nc . It also supports different switches. To listen to port 1234: $ netcat -l -p 1234...

I didn't know how hard it was to vertically align something to the middle until I had to do it. An excellent writeup about the various techniques (or should I say hacks?) to achieve this is here: http://blog.themeforest.net/tutorials/vertical-centering-with-css/ Here I present a technique with the help of jQuery. To make it simple, what I'm doing is to display a single line of text in the middle of the page instead of at the top. The markup is made simple because the logic is moved to JavaScript. There are two requirements to make this work: The parent container uses relative positioning jQuery code added to re-position the content with absolute positioning
<!doctype html> <html> <head> <title>Vert... For some reason, the following code did not work although...

This is an age old problem. Since it comes up time and time again, I'm writing this down for future reference. Let's start with a two-column layout generated by the 2 Column Layout Generator :
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Trans... It renders like this: The left column is shorter than the right column. How to make the left and right column the same height? Adding height: 100% to the style sheet of the left column doesn't cut it. There are several hacks, none of them are straightforward: In search of the One True Layout Faux Columns Creating Liquid Layouts with Negative Margins In short, there's no instruction in CSS that tells a DIV that its height should be 100% of that of the...

If CSS3 border-image is properly supported, making a rounded corner box is very easy. You just need a round corner image like this: The following markup:
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN" ... would render like this (try it in Firefox 3.5 and Google Chrome): However, IE as of version 8.0 does not support border-image . So until border-image is reliably supported in all major browsers, we still have to rely on tried and true tricks to make it work. In general, I found three general categories of tricks to make rounded corners: Good old tables. This trick creates a table of 9 cells and uses the 8 cells on the perimeter to render the borders and rounded corners. The central cell is used for...

The output from cat /proc/meminfo looks like this (enter the shell with abd shell ):
# cat /proc/meminfo MemTotal: 94096 kB... To quote hackbod from stackoverflow : Finally there is the command "adb shell cat /proc/meminfo" that gives a summary of the overall memory usage of the system. There is a lot of data here, only the first few numbers worth discussing (and the remaining ones understood by few people, and my questions of those few people about them often resulting in conflicting explanations). These are the meanings of the first five rows: Term Meaning MemTotal The total amount of memory available to the kernel and user space (often less than the actual physical RAM of the device, since some of that RAM is needed...
