[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:


a
b


Good luck.

PHP string replace all except numbers and chars

PHP multidimensional array check

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 )

PRIMARY KEY (id)
) ENGINE=MyISAM;

Md5 is coding. And most of time it used for mysql database's passwords. After coding password with md5 you will get 25 chars length string.

Sometimes people required to create md5 force way. So just input your password or whatever else string into string field and press genereate md5.

Here is my result for "password" string md5 generation:

Optimize your website

At work as programmer i need to optimize page load time.

So here is some tweaks which you can use for your own web sites.

1. Optimizing your CSS and JS ( Javascript, Jquery and so on... ).
All pages uses css and js. Most of time they are huge. like 50-500 kb for css and same for JS.

Most of time i use the tool to see how fast my page is loading:

http://tools.pingdom.com

Best way to optimize CSS is:
Explode CSS files by parts and use only required ones for pages you are using. After compress it with such tools as http://www.cssdrive.com/index.php/main/csscompressor. And in same time combine these ones together into one single load ( search google for CSS.php combiner ).


Best way to optimize JS is:
Explode by files and use only required code you are using. Compress these files with tools like this: http://www.compress-javascript.com/ ( Some codes don't work after compress, you can try to find another good compressor which will compress better than this one. Let me know if you find anything.. )
In same time combine them with combiners into one file. ( search google for JS.php combiner ).

2. Cache! Best way to optimize website is to use cache.
There also some good tweaks about cache. For example using GZIP cache.
Most of time gzip compressed code with 80% success. For example if you code is 100kb, gzip will compress into 20kb and load it into user browser.
To check gzip compression im using such tools as this one: http://www.whatsmyip.org/http_compression/

3. Images! Less images - better. But as you know, logos and so on.. are important for web sites.
Big web sites as facebook using very nice technique - one big image with all images: http://static.ak.fbcdn.net/rsrc.php/v1/zi/r/uVYVvAILt0K.png

4. HTML, PHP code optimization gives some results too. Spaces, tabs, else { } and so on are pretty good on lowering some kbs...
but each kb less will be some gigabytes less for server load per day-week-month if your web site is big!.

5. Javascript lazyloading - it is very nice tool for loading images. It will load image only if user sees the image. If the image is not in visible spot, it will not be loaded.

And remember, that visitor is important of all web sites!

PHP remove all characters and leave only numbers

function which will remove all but leave only numbers for php:

$string = preg_replace('#[^0-9]#','',strip_tags($string));

p.s. If you are looking for function to delete all except chars and numbers look here:

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';
}
});
});

MYSQL - Deleting duplicated entries huge DB

The problem occurred when i had to delete duplicated entries

like this:

id name value
502 john null
503 john null
1000 john smith

solution for this was to group by name and export them to other table

so here is mysql codes:

1. Exporting to new table

CREATE TABLE new-table-name as
SELECT * FROM old-table-name WHERE 1 GROUP BY [column by which to group];

2. Renaming old and new tables ( 'different-new-table-name' , not new-table-name )

RENAME TABLE old-table-name TO different-new-table-name;

3. And finaly renaming new table to old table's name

RENAME TABLE new-table-name TO old-table-name;

Google chrome Program too big to fit in memory [ Solution ]

Today for first time i meet the problem.

I was browsing as always... many tabs - like 10. Most of them are text. Suddenly my pc showed BSOD. After restart google chrome want start. And shows cmd windows for a second.

With cmd.exe ( start > cmd.exe ) , you can run same google chrome to see error message. It was - "Program too big to fit in memory".

After some google searches i read nothing interesting but only complains and questions about the problem.

I was not worried about my bookmarks because im using google sync.

1. So i just opened firefox.
2. Went to Google Chrome download page.
3. Downloaded / Ran setup
4. After installation all came back to normal.

Also last session was saved... and i could see pages which was opened before BSOD.

In worst situation you can lose your bookmarks. So its up to you...

Leave a comment if your bookmarks haven't erased after install. If you didn't used google sync. Cheers.

Hope it will help you guys. 

Input is not proper UTF-8, indicate encoding !

I faced with the error while exporting huge xml.

My solution for this was changing the code:

foreach($adData as $itemData )
{
$xmlData .= "<item><![CDATA[".$itemData."]]></item>";
}

Into this:

foreach($adData as $itemData )
{
$table = array('&' => '&amp;', '<' => '&lt;', '>' => '&gt;', '"' => '&quot;');
$data = str_replace(array_keys($table), array_values($table), $itemData);
$date = str_replace(" ","",$data); //there is one strange square symbol. after converting into chars //for blogspot it was removed :(
$data = htmlspecialchars(html_entity_decode($data, ENT_QUOTES, 'UTF-8'), ENT_NOQUOTES, 'UTF-8');
$xmlData .= "<item><![CDATA[".$itemData."]]></item>";
}

Hope it will help you solving your problem.
Anyways. Good luck!

Video editor online free - JayCfut

I was trying to find freeware which will silent videos audio track and add another one. I tried some of freewares like - wax , windows movie maker, avidemux ( linux video editor on windows ).

It is website which contains java video editor, and so you can edit videos online.

The company was founded early 2007 and since 2008 we license the video editing tool to other companies and websites.
