I’ve just changed the engine for my blog from Wordpress 2.3 to Wordpress 2.5.
The change is not visible for the reader but there’s a lot going on in the dashboard, starting with the layout, dashboard widgets, multiple file upload, etc… To get the full list of the changes, please look at the official Wordpress blog.
Recently I’ve been reading “High Performance Web Sites” (look at amazon).
I think it’s a good book who can be recommended to all who do even little bit of front end development. The book describes 15 rules (regarding CSS, JavaScript, etc.) that should be followed in order to deliver high performance web sites. It’s rather short (c.a. 150 pages) and easy to read, but the suggestions described by the author can be helpful while you work.
I believe Reporting Services are very powerful tool for report generation. Unfortunately the installation process can be time consuming as you might face some problems with the cofiguration… Of course such problems can be the reason of unsufficient knowledge in SQL Server configuration and management, etc.
Anyway, blank Report Manager screen can be one of the problems, which displays as shown below:
This issue can be easily fixed by unsetting Enable anonymous access feature for either Reports or ReportServer virtual directory in IIS. In my case (on Windows 2003) I had to switch that of for both that virtual directories.
To do that follow the steps below:
If you’re bored with standard Windows XP Themes and you’d like to try something different, have a try with Windows XP official Zune Theme. You can have a look at it on Softpedia.
I haven’t had any problems with it and I’m pretty hapy with the effect 
What is feedmap? Let me cite its authors:
… feedmap is about mapping your blog! Using FeedMap you can tell the world where you are blogging from! Or you can simply search for bloggers right around where you live! Or even better let other local bloggers to discover your blog…
I had a look at this service and I must say its idea is very good. Really you can discover blogs of authors that live in the same town or are even your neighbours. And of course you can make your own blog more discoverable. However, I believe the authors need to improve some things (layout, minor issues and some more important stuff, like not working link). Anyway, great idea! I wish feedmap luck!
Of course I submitted this blog (info on feedmap), and my photoblog (info on feedmap).
I’ve just encountered a movie which describes some of Google Analytics features, which are described there too.
I think it’s worth watching this movie even if you’ve been using this tool.
Usually to print some ouptut you’d use System.out.printl() or System.out.println() method. It’s easy to use but you can face some difficulties in providing output formatted in a specific way.
To format output you can use either of the following methods (they work the same)
System.out.format(String format, Object... args)System.out.format(Locale l, String format, Object... args)System.out.printf(String format, Object... args)System.out.printf(Locale l, String format, Object... args)This is the way how those methods should be used:
%[argIndex$][flags][width][.precision] conversion

A few months ago I wrote about Xobni, a plugin for Outlook. I created that post basing only on what I learned on their homepage.
A few weeks later Xobni team sent me an email with a special link to the installation file. I downloaded and installed Xobni, and played with it.
I’ve been using it for a couple of weeks now and I must say I’m very satisfied! I’ve been using it most to find emails or attachments in my Inbox or Archive folder; this works pretty fast and is very handy. Searching mailbox has never been easier It’s also interesting to see the email statistics like characteristics of email traffic, who you keep in touch most frequently, etc. There are even a few more useful features which you can discover yourself
To sum up, I really recommend this Xobni. It’s a great piece of software that can save you much time!
It’s a rule that == is used to compare references, not values. To compare values for equality equals() method should be used.
However, as of Java 5, you can also use == to check if two objects’ values are the same… But it works only for the following wrapper objects, if their primitive counterparts’ values are the same:
