Tech this week ( Jan 9 – Jan 16,2009)

Hello all and welcome to 2009’s  first issue of this (not so regular) thread at my blog.

Nokia licenses QT under LGPL: After acquiring () Trolltech , Nokia has decided to move license QT under LGPL instead of QTs  Q Public License A major issue with QTL was its incompatibility with the GNU GPL.
This made it extremely difficult to link QT with other GPL covered programs. With QT moving to LGPL this limitation is gone!   The decision has been hailed by many in the FLOSS community. QT is already cross platform and changing the licensing model will make is more ‘corporate’ friendly.

Meanwhile,it has been found that there could be some issues with LGPL 2.1 and the various C++ template classes  in QT.  Though QT’s signal’s and slot mechanism does not use C++ templates, templates are used  with the container classes in QT. Template instantiation actually  nests (QT LGPL code) into the end user code.  So, we have a problem if the end-user licenses his code under non-LGPL! For the update on this,you have to look here .

I am not sure how this move would thwart GNOME’s efforts in getting into the mobile Linux world.  I hope both these libraries have their own  pro’s and cons and would continue to be widely used.

Windows 7 in beta: Last week also saw the release of Windows 7 as a beta. The Windows 7 buzz was around for quite some time.  User response has been overwhelming for this product. More than desktop, I think the strategy is to run Win7 on net books  as well and removing dependence on WinXP for this.

get Windows7 run with a lesser memory than Windows XP SP3  and lesser install space than Windows Vista!

I believe Windows 7 will finally allow Windows to stop its support for XP after so many years.

HSPA+ is considered as an enhancement to HSPA and achieves high data rates by including MIMO technologies. The current HSPA+ Release 7  provides  downlink data rate of up to 28Mbps and an uplink of 11Mbps. Future revisions may support higher bandwidth.

Linux kernel 2.6.29 -whats new : The merge window for the next release of the Linux kernel closed recently . Heise online has been running a series on the new and noteworthy features in this release.
An important feature would be the integration of Intel’s WiMAX stack into the kernel mainline by Greg Kroah Hartman. The next noteworthy feature is the integration of Kernel Mode Setting (KMS)  feature into the kernel mainline. Kernel Mode Setting would add a rich boot experience to Linux desktops .  This feature is already present in the latest Fedora release and many were impressed with the seamless boot process of that release.  Now that KMS makes to the linux mainline other distributions would also benefit from this. For a complete coverage on the release, you can have a look here.
