Voice over LTE gets a SPEC from VoLGA forum. More details, look at the dailywireless blog Voice over LTE Gets a Spec: VoLGA And the forum, http://www.volga-forum.com/ -srinivas.

Its a great trail, the project allowed that, to run Ubuntu from (on) windows, just like a native application. And the project is claiming that, one can install Ubuntu applications from synaptic manager, and ubuntu access the filesystem(drives) directly. Probably it will become a development platform, just like cygwin. You can see the project here. http://sourceforge.net/projects/portableubuntu/ http://portableubuntu.demonccc.com.ar/ -srinivas.

First, google's web browser, open source based, Chrome. Now today they announced a Desktop OS based on Open source and Linux kernel as Core, but an Web based Front end, and very simple to use for the user. A very interesting idea and move, they said they are going to come by mid of 2010. For more information read their blog at this, http://googleblog.blogspot.com/2009/07/introducing-google-chrome-os.html -srinivas.

It is the thought, at the starting of Zibee spec become to public, if it goes to Linux kernel there would a lot of applications, just like wi-fi. Now i observed through the Linux-Zigbee project it gone into the 1st cut, in 2.6.31rc1 linux kernel, net802154 under net/ and drivers/ folder. Similar to wifi iwpriv, there is userland tools to configure, etc and the fake radio driver feature allows the zigbee people to test with out hardware. Very interesting. http://sourceforge.net/apps/trac/linux-zigbee/ -srinivas.

Here are some good blog sites on LTE, Femtocell related. http://lteworld.org/ http://ltewatch.blogspot.com/ http://en.wordpress.com/tag/lte/ http://3g4g.blogspot.com/ http://www.femtohub.com/ -srinivas.

Am just read in dailywireless, a new alliance which is coming up a new spec to use the unlicensed 60 GHz to transfer the HD Video. More you can see at the site, http://wirelessgigabitalliance.org/ About wireless HD, from the site, http://www.wirelesshd.org/ and one more interesting alliance, WiMedia, http://www.wimedia.org/en/index.asp and Wireless Home digital Interface, WHDI, http://www.whdi.org/ -srinivas.

I am interested and now and then i follow the forums news and updates, IP/MPLS forum: http://www.ipmplsforum.org/ Frame Relay forum: http://www.ipmplsforum.org/tech/fr_ia.shtml ATM forum: http://www.ipmplsforum.org/tech/atm_specs.shtml Wimax forum: http://www.wimaxforum.org/ IPv6 forum: http://www.ipv6forum.com/ 3GPP forum: http://www.3gpp.org/ 3GPP2 forum: http://www.3gpp2.org/ Femto cell forum: http://www.femtoforum.org/femto/index.php Next Generation Mobile networks: http://www.ngmn.org/ GSM world: http://www.gsmworld.com/index.htm Broadband Forum: http://www.broadband-forum.org/technical/trlist.php Zigbee Alliance: http://www.zigbee.org/ -srinivas.

This is based on LGPL license. The project is designed in such a way that it can be integrated to any of the product line which really needs the serial way of CLI or through ethernet, (a CLI- command line interface). One has to design their callbacks and have to register with the APIs provided with the libcli.  They can group together according to their requirement. So that the command hierarchy depends on the registration. I am easily able to integrate with the eCos 2.0. Am faced only the problem not having fork() in eCos, but similar requirement is mimiced with the threads. And checks around the select() call in the cli_loop() function is changed to work with the serial interface, with minute flag checks around the call. You can see the initial host of the project here. http://sourceforge.net/projects/libcli http://libcli.sourceforge.net Now it is moved to Code google site, you can the latest of libcli from this link. http://code.google.com/p/libcli -srinivas.

In just around a months of time from Beta, 3.0 release happened. It is mentioned on the site  http://ecos.sourceware.org/  . And on the mailling list annoucement can read from this link  http://ecos.sourceware.org/ml/ecos-announce/2009/msg00000.html -srinivas.

Asterisk is one of the Open Source PBX software. Which supports on many platforms include GNU/Linux, All BSD unix systems and QNX. It is the package comes in the Debian Linux distribution. It is having vast features, and supports many of the VoIP protocols include, SIP, H.323, MGCP, SCCP. You can get a clear list of supported features from this link http://www.asterisk.org/support/features and more about the Asterisk from the link http://www.asterisk.org/support/about Another Open source PBX project is FreeSwitch. The comparisions with the Asterisk, can get from the link. http://www.freeswitch.org/node/117 And features from the link http://wiki.freeswitch.org/wiki/Specsheet -srinivas.

There are two good open source projects for the VPNs. One is OpenSwan, and IPSec based. And the second is OpenVPN an SSL based. Basically OpenSwan uses the IPSec functionality in the Kernel, and user space tools and front end. But the OpenVPN is based into userspace functionality, so interoperability is question when compared to OpenSwan. OpenSwan project: http://www.openswan.org/ OpenVPN project: http://openvpn.net/index.php/home.html Both the projects comparision and configuration information you can get from this Debian Administration website article http://www.debian-administration.org/articles/563 -srinivas.

QNX is one of the Microkernel based embedded real time operating system, now a days am looking into. I just come to know from its site, it is become for open and through their community development site, calling it as Foundry 27, you can get the CoreOS, Core Netowrking, Drivers and BSP related source code. And its having Hybrid model of License, unlike GPL2, if you want to give it back to community for Open, you can, otherwise you can keep it for your commerical. http://licensing.qnx.com/developer-licenses For core os, see the link, http://community.qnx.com/sf/projects/core_os For the core networking, see the link http://community.qnx.com/sf/projects/networking For the core file systems,  http://community.qnx.com/sf/projects/filesystems -srinivas.

I have come from lkml.org browsing, just like that went to vyatta.com (a commercial product company), making routers, using x86 based hardware and their promoted opensource software site, vyatta.org. From the site, their products rates comparision, looks very impressive. This stands one of the example for the open source economics on the product developing companies. http://vyatta.com/products/product_comparison.php -srinivas.

From past 4 years am working on eCos 2.0(GPL) based product. Its an RTOS, i have learned a quite a bit of RTOS concepts from this OS only. Its a simple and also integrated with the Redboot bootloader. So one can even concentrate on the bootloader along with the OS, according to their interest. Now eCos 3.0 beta1 have come out. One can see the site. http://ecos.sourceware.org/ml/ecos-discuss/2009-02/msg00097.html -srinivas.

Since 1999, or even a couple of years before am started following the Linux. At that time they used CVS, and then moved to BitKeeper. THe kernel people have come out their own distributed souce code management tool called git. Usage is very easy, and a lot of good tutorial and also video tutorials are available from the site. http://www.git-scm.com/documentation -srinivas.

There are some good web sites for the Linux devices, and Linux kernel, and also Wireless blog and tecnology news sites. For Linux Devices - which updates the new Linux ports, products, and Linux based solutions http://www.linuxdevices.com For Linux Kernel -  which gives the Linux kernel git repository.  http://www.kernel.org And can get from the site, the Linux source cross reference, http://lxr.linux.no/source For daily, the happenings in the Broadband wireless(Wimax), and the relevent technologies, the complete blog, http://dailywireless.org For latest happenings in the technology space, one of the good site, http://news.cnet.com -srinivas.

When following the freaklabs.org on Zigbee, just found one more interesting blog site. It is Wireless sensor networks blog, http://www.wsnblog.com  .  From it, i found that it is started in May 2006. So one can get good amount of good  writings from then. -srinivas.
