Easy access to MySQL data on shared hosting service

<p>MySQL databases are often the main data-source of web applications when it comes to shared hosting services with very limited possibilites (no system service support, no scheduling, no in-memory database, ...). Often, management or visualization of such databases is not easily done, since no admin utility is installed, no remote connections to the database are allowed, and access by the sql binary (via SSH) is not user-friendly. A better way to manage databases visually in such cases is the challenge.</p>

Install the usb-modem ZTE MF626 HSDPA in Ubuntu 9.04

<p>An austrian discounter internet provider has sold not widely spread usb-modems with his prepaid cards for HSDPA internet connections. With Windows this modem works fine because the drivers are delivered with the modem. But with Ubuntu 9.04 only common usb-modems work without laying hands on the system. A nice addon would be if the modem works with the built-in network-manager of Ubuntu, so you can just click on the modem and connect to the preset internet provider, respectively the right access point, without providing your username and/or password every time.</p>

Connect to wlan via vpn under Ubuntu 9.04

<p>To connect to the internet via vpn and wlan you first have to get an ip address from the wlan accesspoint. After this you can build up the vpn tunnel and register yourself in one step. This is safe and comfortable if you are working at your workplace. With Windows XP (SP3) this works without problems.</p><p>But when I use Ubuntu 9.04 I cannot connect to the server to register. On the TU I can only receive an ip address, open a browser an type my username and password in the login-field.

CSS-based layout with fixed menu

<p>CSS-based web page layouts are more and more substituting table-based layouts, since processing of table-based layouts is more complex (which may prevent screen readers from correctly reading a page), and not easy to style. Pure CSS-based layouts allow complete customization by simply exchanging the style sheet.</p><p>The task of creating a pure CSS menu, which is located at a fixed position, emerges from the need for a menu which will always be available, wherever the user is scrolling.

Search engine and user friendly CodeIgniter URLs

<p class="MsoNormal"><span lang="EN-US">CodeIgniter is a PHP based programming framework which implements the model-view-controller paradigm. All HTTP requests have to pass the central index.php file (provided by CI) which initiates the framework controllers to load the views and render a site. So it is not possible to directly call a specific site by entering its URL. To open a specific site the according controller has to be called by passing its name as HTTP-Get-Variable to the central index.php.

Multi-select file upload

<p class="MsoNormal"><span lang="EN-US">The standards file upload dialog provided by HTML is restricted to one file per dialog. It is not possible to select multiple files in one single dialog and upload them all in a single step.

However, there are web services &ndash; e.g.
