Recursive drawing

Have you wondered how to draw this ones easy? It calls "Recursive drawing".

I made this one by my self in few minutes.
Recursive Drawing by artist Toby Schachman is a simple web app for creating images out of recursive shapes, in other words, shapes that repeat in a self-similar way.
Try yourself: http://recursivedrawing.com/
Recursive Drawing is an exploration of user interface ideas towards the development of a spatially-oriented programming environment.

{
  for($month=1;$month<=12;$month++)
  {
    echo $month."'th month of ".$year_s." has: ".cal_days_in_month(CAL_GREGORIAN, $month, $year_s)." days

Atribute of reg:
var emailReg = /^([\w-\.]+@([\w-]+\.)+[\w-]{2,4})?$/;

Joomla K2 watermark image

We need to edit file - item.php which exists in our administrator folder, full path:
\administrator\components\com_k2\models\item.php

first we need to define the variable:
$img_url_watermark = "../images/watermark.png"; //(line 202)

near the comment line
//Original image

Then we need to paste the lines after each image comment to which we want to add watermark (i recommand not to add to small and xsmall... images )
$handle->image_watermark = $img_url_watermark;
$handle->image_watermark_position = "TL";

Than we need to add the code:
//gallery watermark
if($dir = opendir($savepath.DS.$row->id)) {
while (false !== ($file = readdir($dir))) {
$handle = new Upload ($savepath.DS.$row->id.'/'.$file);
$handle->allowed = array('image/*');
$handle->file_auto_rename = false;
$handle->file_overwrite = true;
$handle->image_resize = ture;
$handle->image_x = 1024;
$handle->image_ratio_y = true;
$handle->image_watermark = $img_url_watermark;
$handle->image_watermark_position = "TL";
$handle->image_convert = "jpg";
$handle->jpeg_quality = 85;
$handle->Process($savepath.DS.$row->id);
$handle->Clean();
}
closedir($dir);
}
//end

After the code:

if (!JArchive::extract($savepath.DS.$handle->file_dst_name, $savepath.DS.$row->id)) {
$mainframe->redirect('index.php?option=com_k2&view=items', JText::_('Gallery upload error: Cannot extract archive!'), 'error');
} else {
$row->gallery = '{gallery}'.$row->id.'{/gallery}';
}
JFile::delete($savepath.DS.$handle->file_dst_name);
$handle->Clean();

Its about 430~ line

That is all.... done :)

p.s. some sources where the solution was fount

Prestashop CMS block location header



Several days ago i faced with prestashop problem. I tried to hook right column cms block to header. But as prestashop developers says, that it was developed to hook only left or right side.

So here is my solution for this:

in global.css i changed right_column class position to relative and moved it up.

CSS looks like this after my changes:

position: relative;
left: 0px;
top: -200px;
width: 191px;
margin-left: 21px;
overflow: hidden

After this my center_column looked weird ( not full width ) and chaing it's width changes everything ( right_column drops down and starts to move... ). So i figured out this solution for the place: I changed center_column position to absolute, added padding-left so it dont overlay on left_column and added width which i was required from the beggining.

CSS looks like this after my changes:

position: absolute;
padding-left: 290px;
width: 810px;
margin: 0 0 30px 0;
overflow: hidden


Good luck with you prestashop hacking!

[Solution] user agent stylesheet override site stylesheet on Chrome but not Firefox


My problem was this: i wanted to put bold on text which was in select's option by putting style - wont-weight. I had succeed only on Firefox. Because chrome user agent stylesheet were overriding my stylesheet.
I tried to solve the problem for hours. Finally with my friend's help i found the website - electrictoolbox. And it says that only firefox allows to do that... that means we cant use wont-weight on chrome for option, select and optgroup.

My solution was for the bold text changing wont-weight style into color, with dark color for normal text and lighter color for bold required. Also i needed disabling option of bold, so i just added " disabled='disabled' ". That is all..

My result:


Good luck.

Today i faced with problem that array had array inside it. It means that the array is multidimensional. So i was forced to recheck the array check with function is_array to new check. Here is the code of check:


function is_multi($a) {
    $rv = array_filter($a,'is_array');
    if(count($rv)>0) return true;
    return false;
}

CSS compressor

Today i have created my own css compressor. I often do css compression, but i always used other sites. So today i created my own and using it! All you need just copy your css code, paste into css code field and press compress. The compressor will compress css code for you. Mostly i get 20% compressed code. Compression can be high and can be low, it all depends on your CSS code writing. The more compressed code you write, the less it will be need to compress.
So now you dont need to write it compressed. Just write as you like and after compress into compact size called "min" aka "mini" ( most of programmers use .min tag for jquery files , like jquery.blabla.min.js )

Broken image. Failed to load images fix with JQuery

Today i was solving problem with failed to load images. There was 2 solutions for this - 1) php with getimagesize and 2) JQuery check.

getimagesize showed me warnings so my choice was JQuery.

And it was great choice, because using jquery is always fun.

Code i used for all img ( CSS attribute ):

$(window).load(function() {
$('img').each(function() {
if (!this.complete || typeof this.naturalWidth == "undefined" || this.naturalWidth == 0) {
// image was broken, replace with your new image
this.src = 'http://www.example.com/replace_no_image.jpg';
}
});
});

Solution 1030:Got error 139 from storage engine

Today i meet with one big problem while updating MySQL database. The error is 1030:Got error 139 from storage engine.
The problem is that rows has limit.
I was trying to change limit, but there is no need.

Solution for this is very easy. All you need to change ENGINE of your table. While engine almost does nothing, and it will not effect on your values. ( Please read http://dev.mysql.com/doc/refman/5.0/en/storage-engines.html , before doing something ).

I had no time to read this so i executed the query:
ALTER TABLE `table_name` ENGINE = MYISAM

It worked for me. Hope it will work for you too.

CSS trick to cover with perfect background width and height


There is one cool trick to fill place with background, even if their sizes different. Just use the code for css:
body {
background-image: url(bg.jpg);
-webkit-background-size: cover;
-moz-background-size: cover;
-o-background-size: cover;
background-size: cover;
}

The goal here is a background image on a website that covers the entire browser window at all times. Let's put some specifics on it:

  • Fills entire page with image, no white space
  • Scales image as needed
  • Retains image proportions (aspect ratio)
  • Image is centered on page
  • Does not cause scrollbars
  • As cross-browser compatible as possible
  • Isn't some fancy shenanigans like Flash

We can do this purely through CSS thanks to the background-size property now in CSS3. We'll use the html element (better than body as it's always at least the height of the browser window). We set a fixed and centered background on it, then adjust it's size using background-size set to the cover keyword.

Works in

  • Safari 3+
  • Chrome Whatever+
  • IE 9+
  • Opera 10+ (Opera 9.5 supported background-size but not the keywords)
  • Firefox 3.6+ (Firefox 4 supports non-vendor prefixed version)

While developing on new project which was created not by you, the software always is good for searching something..
Big plus of the software is that it is searching in sub directories... and it searches in text files! And most important it works just great!

Searches text files for strings and combination of strings. Has useful or / and / and not search combinations, and can also use regular expressions. New in version 3, is the built-in viewer / editor that highlights the matched strings and lines.

Rounded corners border CSS Problem in IE [ Internet Explorer ] [ Joomla ] [ Solved ]


Here you go.. There is an css code for "good" browsers to change your div's corners to rounded ones. But "bad" browsers such as Internet Explorer ( IE - IE6, IE7 and so on... doesnt works pretty good under this conditions.. ), so here is solution for this problem.


CSS CODE EXAMPLE OF DIV WITH CLASS = "box"
.box {
-moz-border-radius: 15px; /* Firefox */
-webkit-border-radius: 15px; /* Safari and Chrome */
border-radius: 15px; /* Opera 10.5+, future browsers, and now also Internet Explorer 6+ using IE-CSS3 */
-moz-box-shadow: 10px 10px 20px #000; /* Firefox */
-webkit-box-shadow: 10px 10px 20px #000; /* Safari and Chrome */
box-shadow: 10px 10px 20px #000; /* Opera 10.5+, future browsers and IE6+ using IE-CSS3 */
behavior: url(ie-css3.htc); /* This lets IE know to call the script on all elements which get the 'box' class */

}

There should be like this: "behavior: url(path/to/ie-css3.htc);"

Download url of the ie-css3.htc file. Put the file into root and css folder. ( and into other folders in other cases.. ^^ ):
