innerHTML problem with internet explorer (supposed)

I lost some time to debug this

$("#link").click(function(){
   $("#target").load('url/to/load');
});

The problem is on Internet Explorer (all version) that refuse to load data in #target, using $.get and innerHTML(data) do not help. The problem is with no well formed html! Internet Explorer refuse to load in dom a malformed html.

Email from your host you are banned (mail php security matter)

I found this in a server:

$header = "From: <".$_REQUEST['email'].">\n";
#... 
mail($from,$subjet,$message,$header);

$_REQUEST['email'] came from a form input ...

Here $_REQUEST['email'] should be, at least, stripped by all \n no matter on how you trust to js code..

$from = $_REQUEST['email'];
$from = str_replace("\n","",$from);
$header = "From: <$from>\n";

grep over ssh in emacs

M-x grep command is very useful in a number of situation, because, for example, it give you direct access to all matched file ...

But there is not so intuitive how to use grep when opening file via ssh, this is the trick:

First generate a key pair and upload public part to the remote server:
(suppose remote host/user is B/b)

ssh-keygen -t rsa
#...
ssh b@B mkdir -p .ssh
cat ~/.ssh/id_rsa.pub | ssh b@B 'cat >> .ssh/authorized_keys'
ssh-add

be sure to use ssh-agent in order to use ssh-add
