Resizing an NTFS partition with Linux

If you have a computer where you already installed Windows and you wish to install Linux as well (dual boot), you may want to resize the NTFS partition to get more space for the Linux partitions. One way it to use Gparted (Gnome Partition Editor) – http://gparted.sourceforge.net/ with a boot CD. Here are the instructions: • Boot from the CD • Hit <ENTER> when you see the message “Boot:”. • Select language, keyboard and screen resolution from the menus. • The partitioner should start and the following steps are intuitive More details are available @ http://mlf.linux.rulez.org/mlf/ezaz/ntfsresize.html#example It is also possible to do it with a USB Thumdrive if you do not want to burn a CD and your bios can support booting from a USB device. http://gparted.sourceforge.net/liveusb.php

Sigma Designs EM862X Resources

We are using EM8623 for the development of set-top-box and digital signage applications. In order to develop for that platform, an SDK must be purchased directly from Sigma Designs. However, the linux kernel is open source so companies need to release the source if they modified it in their products. For example, you could download the GPL source released by Kiss Technology – http://www.kiss-technology.com/files/firmware/GPL.zip. This is only the GPL source for your reference, after that there are also sigma linux drivers (not released by sigma) and not GPL, and the MRUA package that needs to be purchased from Sigma Designs. One the challenge of using EM862X platforms (EM8620L, EM8621L, EM8622L, EM8623L etc..) is that it has no MMU (Memory Management Unit) and that may make the software debugging very interesting.. You may experience spectacular crashes, kernel panic without any apparent reason. But most of the time this is due to […]

Software Development Cycle Tools

In order to manage software development with a small team, we use the following tools: Version control software: e.g. CVS, Subversion, git… Bug tracking software: e.g. Bugzilla Nightly build scripts or continuous integration software: e.g. CCNet For our linux based projects (embedded software), we use CVS, Bugzilla and nightly build scripts (with crontab) For our Windows-based projects (.NET Framework), we use CVS, Bugzilla and CCNet.
