During last few weeks we’ve found that a few of our client’s sites are infected with malicious javascript code, which appeared to be the result of a virus work. The virus behaviour is similar to so-known Gumblar virus. Here is a short summary of what this virus does:
Wordpress has already become a very popular free blog engine mostly thanks to the extensibility with the help of plug-ins. Since version 2.1 famous Wordpress Widgets were integrated. This mechanism allows to manage blocks in sidebar. In more difficult sites which are built with WP often there is a need of using different sidebars on different pages. Here come troubles with using widgets. The majority of widgets can be added only once. You can easily find articles on how to create widgets in the Internet. The main article is on Wordpress codex site (read wordpress widgets API article).
The article ends on section “Widgets - One or many ” with such words: “… Wordpress is doing the work for you to instantiate your Widget multiple times if you follow some rules.”. Actually in this article we want to describe these rules, because we can’t find them … read more
Our clients often ask us to add a few dynamic javascrtipt effects to their website in order to make it more attractive. Many of them look so intuitive and natural that people can think that they are very easy to add and there are common standard tools for that which you can include where appropriate. In fact the effects which look the same in browser can be coded very differently. Unfortunately there are no standards for such things in web development yet (like W3C standards for XTHML/CSS) and developers just use various JavaScript libraries which save much time for doing such things. From variety of such libraries we separate jQuery library as the one which we find the most easy to work with. It can also be extended by writing the plugins and people wrote quite a lot plugins for jQuery so far.
One can say: JavaScript is good enough, why … read more
With this article we continue to share our experience of implementation the websites with free popular engines like WordPress , Drupal , Joomla etc. After delivering hundreds of such projects to the clients we collected number of tips/solutions which we think may be useful for other developers or clients. If you are interested in solutions to some problems you faced with please feel free to contact us - we’ll try to cover them as well.
If you ever tried to develop the WordPress sites you most probably faced with the problem we are describing. When you develop a WordPress site there is 99,9% chance that after development you need to move it from one server to another and even not just once. At the first glance there are no issues for more or less experienced developer - you … read more
We had no time to get used to one WordPress as the next was released. Still it is rather good than bad. Let’s look at the new WordPress numbered 2.7.
I would like to draw your attention to Turbo button in Tools. The developers took care of the admin area cache using Google Gears. Google Gears is already in use in such Google services as Google Docs, Google Reader. The main objective of this technology is the use of this service offline, and synchronizing of the local version with online when there you are online again. It is easier to explain this way: when you are offline, you can use the services, and when you are online again, all the changes will be written into the service.
Unfortunately caching (with the help gears) it is not realized completely in WordPress 2.7, you can visit all those admin pages without the Internet which … read more
These days most frontend CSS-developers face with a problem of using custom fonts when coding web pages. The technology of sIFR (Scalable Inman Flash Replacement) became very popular because it gives rather flexible and easy to use solution of this problem. If you are new to this technology please check sIFR Documentation for more information.
Though sIFR gives many useful additional abilities for the developers there is one thing which is not trivial to do with sIFR. Imagine that you need to highlight some parts of the sIFR text with different color(s). The solution which cames in mind is splitting the text into several tags and applying sIFR to every tag individually. Unfortunately this doesn’t work in many cases because of impossibility to make the width of sIFR element flexible, so more elegant solution needs to be found.
If you ever tried to find ready-made solution you’ll definitely find the … read more
Free 3d-party CMS.
Official site: http://drupal.org .
Advantages: templates control; system architecture; API; taxonomy; community.
Disadvantages: difficulty of working without preparation.
If you wish to completely control appearance and functionality of your site (level of control depends only on your desire), and thus not using dirty methods (like hacks of initial code of the core and modules) and to work only through API and extremely flexible template system – Drupal is for you.
In general, Drupal is first of all a constructor. The core contains only the most necessary — the lowest level which functions will be used in various modules. Basic Drupal installation already has many modules inside (such as blog, forum, search etc.). All is arranged very reasonably and smartly, and there are at least two ways to make what is necessary almost always. Sometimes this choice itself is a problem — it is possible to make … read more
In previous lesson we discussed how to create Wordpress multi-widget. In the version 2.8 Wordpress developers implemented new Widgets API that allows you to register widget in a few simple steps and it becomes multiple by default. We want to review these steps and to show how it works. But unfortunately this method works in Wordpress 2.8+ and is not compatible with earlier Wordpress versions.
First of all Wordpress coders implemented Class model for Widgets. In order to create a widget you need to create new class and extend it from default one. Basic syntax is the … read more

Drupal, Joomla and WordPress are management systems. It is possible to create functional and easy manageable sites without serious financial expenses on their basis. We have decided to compare these systems among themselves and to tell about it in comprehensible language. We have chosen the most important aspects which most likely will interest the ordinary user.
The 7th version is now prepared for release. It is available for testing as beta version. Now 6.6 and 5.12 versions are used. The line of the 5th version hasn’t died as fast as the 4th one because a lot of exterior modules had been written and some of them hadn’t been adapted for the 6th version. New versions are tested for a long time. A core is stable. Bugs in demanded modules usually get fixed operatively. Now a variety of large corporate sites of the world names companies work on Drupal, … read more
