There is one place I really like, because they have a nice waiting room, where you can escape from the cold outside weather. When I opened the door, the first thing I noticed was two nice machines, one for coffee and the other for refresher… I saw them from their side, so when I got in from of them… Well, this is what I saw:

After some research, here is the piece of code you have to enter into the page, which will block the event:

<script type=”text/javascript”>
$(document).ready(function() {
document.onkeypress = stopRKey;
});
function stopRKey(evt) {
var evt = (evt) ? evt : ((event) ? event : null);
var node = (evt.target) ? evt.target : ((evt.srcElement) ? evt.srcElement : null);
if ((evt.keyCode == 13) && (node.type==”text”))  {return false;}
}
</script>
The 13 in the code above is the code for the ENTER key, replace that if you want to block an other keypress.

I have a beautiful Skoda Fabia hatchback, 1.4 16v 75HP… But what is more important: IT IS MINE! :)

Exactly 2 months passed since I bought it, and in this period I can say I got used to it, and… well, I love it! So I am a proud car owner!

As I use it for development, sometimes I am sending the customers links to applications, to check and feedback them.

A problem I experienced is that Google indexed 2 files on my PC. How he did that remains a mistery for me, but for sure this is a HUGE security problem, databases and important mails got public. So, how did I solve the problem? I created a .htaccess file like this:

Allow from xx.xxx.xxx.xxx
Deny from all
AuthUserFile c:\wamp\pwds\.htpasswd
AuthName “Members Only”
AuthType Basic
require valid-user
What the above means:
1. I am now filtering the visitors based on their IP address. Right now only my IP is enabled, the rest will get an Access Forbidden error message.
2. Secondly, for the IPs enabled, there is a username-password combination which needs to be known. They are set in the .htpasswd file, something like:
username:password

Believe or not, but the green and blue spirals from the next image are the same!

If you don’t believe me, open the image with Photoshop and see it yourself. The blue color you see with your eyes is actually… GREEN! Impossible, right?

It’s slow, it’s insecure and it’s stupid. Unfortunately, the fact that it’s more than 10 years old is not stopping some users from using it. Resolving the compatibility issues that usually arise sometimes is unworthy, so here is a little tweak to block the users using IE6 (or lower!):

In the <head> of the html file, include:

<!–[if lte IE 6]>
<script type=”text/javascript” src=”./js/rip_ie6.js”></script>
<![endif]–>
The content of the Javascript file is quite simple:

$(window).load(function() {
$(‘body’).css(“background-color”,”#414141″);

var message = ‘Sorry, but your browser (Internet Explorer 6) is not suported by this site. Please update to a newer version, or try an alternative browser:’;

var links = ‘<br><br><a href=”www.mozilla.com” title=”Mozilla Firefox”>Mozilla Firefox</a>’;
links += ‘<br><br><a href=”www.google.com/chrome” title=”Google Chrome”>Google Chrome</a>’;

$(‘body’).html(‘<div style=”width:600px;height:254px;background:white;margin:200px auto;padding: 20px;”><img src=”js/rip_ie6.png” alt=”" style=”float:left;margin-right:20px;”>’+message+links+’</div>’);

});

As you can see, I offer the user the possibility to download Firefox or Chrome, trying to minimize the damage suffered.
Of course, your web-page needs to have jQuery installed for the above code.

Never heard it before, but it’s so cool I will share it.

Here is a little help (cheat-sheet), which contains all the special characters which you can use in your htaccess file to rewrite the urls:

. (full stop) – match any character
* (asterix) – match zero or more of the previous symbol
+ (plus) – match one or more of the previous symbol
? (question) – match zero or one of the previous symbol
\? (backslash-something) – match special characters
^ (caret) – match the start of a string
$ (dollar) - match the end of a string
[set] – match any one of the symbols inside the square braces.
(pattern) – grouping, remember what the pattern matched as a special variable

I have to set it in a Cookie variable now, so here is what I found, a clean and easy solution:

<script type=”application/javascript”>

function get_my_ip(json){
alert(json.ip);
}

<script type=”application/javascript” src=”http://jsonip.appspot.com/?callback=get_my_ip”></script>
