How to use Unicode, JDBC and Solid Database

It is not always so straightforward to use Unicode throughout your application layers. Let’s say that your Java application’s default character encoding for file I/O operations, JDBC requests and so on is Unicode. In other words you start you Java application on command line for example with: java -Dfile.encoding=UTF-8 If your Solid Database’s string types are not defined as Unicode, there is a little problem.

In the Java JDBC API tutorial it says:

JDBC driver implementations are expected to automatically convert the Java programming language unicode encoding of strings and characters to and from the character encoding of the database being accessed.

So, basically JDBC driver should do the conversion between application’s and database’s character encoding. But in the Solid Programmers Guide it says:

To convert Java applications to support Unicode, the string columns in the database engine need to be redefined with Unicode data types.

Actually Solid’s JDBC driver won’t even return strings in the same character encoding as they are defined in the database, but it mixes all “special characters” wrong. There aren’t any proprietary parameters you could use on the JDBC connection string to choose the character encoding. So, only working solution is to somehow convert strings in a Solid database in the SQL queries before the JDBC driver returns them. Luckily Solid’s SQL implements CAST function. You can for example cast VARCHAR to WVARCHAR which is Unicode variable-length character string. Here is an example: SELECT CAST(name AS WVARCHAR) name FROM... And it works like a charm.

Web Application as Desktop Application with Bubbles

BubblesUse your web applications, like Gmail and Google Calendar, just like desktop applications.

Bubbles is simply but clever way to use web applications or sites just like desktop applications. You just add your favorite web sites in Bubbles settings and after that you can use them in their own windows and they sit in the system tray. Bubbles has some web applications pre-configured and they have some extra functionality. There are Google Calendar, Gmail, 30 Boxes, Yahoo Mail and Flickr. You can for example upload photos by dragging them into Flickr.

Some applications just work so naturally as desktop applications in Bubbles. My favorites is to use SlimTimer with Bubbles.

Minimize the Software Installation Burden by Automating

InstallPadAutomate you software installation by making software list and let the InstallPad do the work for you.

InstallPad is an easy and smart program. It is a little like apt for Windows. You just make a list of your favorite programs with InstallPad or straight in xml format and InstallPad will download and install silently the ones you choose. Yoy’ll get time for more important things.

InstallPad can resume cancelled downloads and can try to find the latest version of the programs. It is still in an early stage, but it is very promising and there are coming features.

Minimal How to Order Windows Taskbar Buttons

Windows Taskbar ButtonKeeping Windows taskbar buttons always in a same order helps to minimize the effort needed to find the right button.

Lifehacker mentioned Windows program Taskbar Shuffle. I Downloaded and installed it and it’s great. It is easy to use and it it feels a natural way to order buttons just by dragging them.

I have been using TaskArrange for ages and it is also working quit well. Nice thing about it is that you can even order the buttons inside groups. You have to open the program in order to arrange buttons so if you place the program shortcut in the Windows quick launch area it is near the taskbar buttons and rather handy to use. On the other hand, there is no need for running background process. Taskbar Shuffle process seems to have about 6 MB memory usage.

I think Taskbar button ordering should be an option in Windows, but these programs fill the gap. Well, nice feature would be an option to save the preferred order. Are there any?

There is also a japanese Taskbar++.

    Cut down version of IE View (Firefox add-ons page). Open Internet Explorer view in a tab. IE View and IE Tab extensions does the same thing, but both of these extensions use C++ code to do their thing, which means they use DLLs, which means they’re larger than the JavaScript-based IE View Lite and more susceptible to changes not only in Firefox but in Windows itself.
  • IE View: Firefox add-ons page :: homepage
    Opens pages in IE via Firefox menus. There is also IE View Lite (Firefox add-ons page), which is, according to the author, a cut down version of IE View. Both of them allow the current page or a selected link to be opened in Internet Explorer. Third option is IE Tab (Firefox add-ons page), which works like IE View but opens IE pages in Firefox tab. IE Tab extension uses C++ code to do its thing, which means it uses DLLs, which means it’s larger than the JavaScript-based IE View and more susceptible to changes not only in Firefox but in Windows itself.

    Now that Tab Mix Plus is Firefox 2 compatible and if you use it, it includes this extension’s functionality.

For example to show only those web site icons on tabs that have a favicon and fade the not selected tabs icons like in Flock web browser (I guess code needs some cleaning):
    @namespace url(;
    /* Fade just the icon */
    .tabbrowser-tabs tab:not([selected="true"]) .tab-icon {
      -moz-opacity: 0.25 !important;
      display: -moz-box !important;
    .tabbrowser-tabs tab:not([selected="true"]) *|tab:not([image]) .tab-icon {
      display: none !important;
    .tabbrowser-tabs tab:not([selected="true"]) .tab-text {

      -moz-opacity: 1 !important;
      margin-top: 1px !important;
    /* Alternatively, kill only default tabbrowser icons (no site icon) */
    .tabbrowser-tabs *|tab:not([image]) .tab-icon {
      display: none !important;
    /* Show icons (no matter what) when hovering over the tab */
