As usually GLink release come after GPix release.

At this moment, I prepare new options functionality, which is developed for GPix.

Thanks for all how help for this release. I hope we remove most of bugs (software have bugs by definition, he-he).

This release contain next changes:

• german and french translation updated
• multi get fixes
• pixel list in admin area(such as in GLink)
• "maintain settings" beatified
• fix admin and user side update for original image
• front-end link in admin toolbar
• 'timezone set' functionality added. Affect web and mysql servers
• original image functinality improved
• original image from admin side

GPix design implement cell per option philosophy and this require to run database each time when I add new option.

So, today I finish to test philosophy 'row per option'. I just tested code which use actively options table with new option 'timezone'. So, to add new options I will need to add html code only. This mean that alter table query will not be required.

Release for YouTube mod can be accessible via phpLD official site only.

This release contains fixes for problem with empty video items.

I am sure phpLD core team will update file on official forums.

memcached is service which provide memory cache storage. It can provide access to cached object via network and it is extrimly fast!

memcashed pecl module is a way which can be used to access cache storage. How it work? It more complicated instead Cache_Lite, but it is fastest. This fact can be explain: Cache_Lite use file system to store cache objects.

One way to speed up web application is to lower database usage. Databases designed to provide very fast manipulation with data in files. Often developer use databases for everything and store session data, user files. This action make tables big and database server work slowly... As result an simple file based cache will speed up application very quick.

An simple example what we can do with Cache_lite:

<?php
// Include the package
require_once('Cache/Lite.php');
$id = 'example_id';
 
$options = array(
    'cacheDir' => '/tmp/', // directory where cache files will be stored
    'lifeTime' => 3600 // expired time
);
 
$Cache_Lite = new Cache_Lite($options);

Ever site have content for cache or pregenerate.

Why cache need to be part of optimization? - if you know what you do and how it is very fast way to lower server load. So, after load is lowered you will have time to think about logical optimization ;)

What we can cache?

• content
• sql results
• functions results
• logical results(which isn't design as separate functions)

next features implement for this release.

• "Remember me on this computer" option for admin
• order continue functionality after user register/login
• back link checker http://forum.tufat.com/showthread.php?t=50238
• multi get/bill, get more that one region per grid functionality

I get more requests for "back link checker", this improvements will be implemented in next version.
Thanks for who help for this release.

Time to time I need to transfer site from server to server very quickly and have not common solution for this, because I have permissios.

Solution is to use http server if you have this one of server with backups or use netcat.
On server side I run

nc -l -p 8080 < mybackup.tar.gz

netcat -l -p 8080 < mybackup.tar.gz

and now can use wget, curl or browser for this url:
http://serveradress:8080

if you sent link to client it will best to do little more:

(echo -e "HTTP/1.1 200\nContent-Disposition: attachment, filename=mybackup.tar.gz\n
Content-Type: application/octet-stream\nConnection: close\n", cat mybackup.tar.gz ) 
| nc -vv -l -p 8080

most of PHP application use session module. Commonly to provide user authentication and most of hoster providers store session files in /tmp directory. Session files from all users/sites at one dir, it is big security risk!

Looks like /tmp is shared between users and used to store authentication information, really bad idea.

Session module allow to change default path for session files (configurable is strong PHP side), so it simple for webmasters and PHP coders to solve this problem, just need to change session path like this:

session_save_path('/home/your_own_dir/tmp');

ini_set('session.save_path', '/home/your_own_dir/tmp');
