During the last day of 2010 news has leaked about a substantial breakthrough in the world of hacking. The quite famous and popular smartphone HTC HD2, also known as Leo, was hacked to run Android 2.2 and 2.3. Originally the phone comes with Windows Mobile 6.3 preinstalled. One needs a lot of space in order to describe all of this OS' shortcomings in the areas of stability, performance, user interface and productivity. However the hardware itself is amazingly good and at par with latest phones from the same and other manufactures.
I’ve just finished reading a very interesting book by Frank Partnoy – “Infectious Greed”. I actually remember seeing it in a library back in 2005, however at that time I chose not to invest the effort into reading it, a decision which I regret today. Nonetheless, better late than never, as they say.
Samsung Galaxy Europa i5500 phone is a cheap (around £100 in the UK) and useful smartphone, running currently Android OS version 2.1. An upgrade is expected in the near future to the new, more convenient 2.2 version. However, since this is a low-end model, the release priority is lower than that of its elder sisters, such as Samsung Galaxy S. Therefore there is still no certainty about the exact release date or schedule. We'll need to wait patiently for the company to make an announcement.

The recently released Microsoft Visual Studio 2010 does not support mobile development for OS versions prior to the new Windows Phone 7. If you want to write software for Windows Mobile 6.5 or lower, you need to stick to Visual Studio 2005. So much for backward compatibility.
Apple has recently announced the long anticipated release 4.0 of their iPhone OS. The list of new end-user features is disappointingly short - the main item seems to be the addition of some GUI multitasking. Many important, easy to add and practical features, already found in the "jailbreak" versions are not mentioned. It is a pity Apple has such tight control on their product and that it takes so long to release productivity related features to the market. I am pretty confident than in a few years they will be punished by other players on the market.
WPF is a very powerful framework for GUI development. Among other things, it contains a unified approach to user input validation. Adding validation in WPF is very straightforward in most cases. However, validating DataGrid rows is slightly challenging. However, the good people of the world has already taken care of the problem and provided quite detailed walk-throughs. I recommend reading this interesting article (WPF DataGrid Practical Examples) about WPF DataGrid.
Monitoring text log files is quite important activity in our day to day programming lives. Unfortunately, Windows operating system does not include convenient tools to perform the task by default. Nothing comparing to

WPF is still relatively new and many developers are only scratching the surface of its abilities. Coming from a different framework, one must learn anew how to do the familiar tasks. Sometimes you need to to trigger a click or some other event for one of your WPF controls, such as a button, a menu or a checkbox, directly from code. There are no methods on the controls to invoke these events explicitly.
