Open-source code for LTE datacard / modem

2012-01-13T07:45:00.000+05:30

This is the open source project evolving on the sourceforge, that for LTE data card/modem.

This is the information about the project.
The LTE data card is a Mini PCIe card used in 4G-capable Xoom tablets. Very similar LTE hardware is integrated within Droid Bionic and Droid RAZR phones, and a common software development line was used for all of these LTE modem modules.

Portable Ubuntu Remix.

2009-08-16T07:06:00.002+05:30

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.

Google Chrome OS?

2009-07-08T19:28:00.002+05:30

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,

Zigbee stack going into Linux kernel...

2009-07-04T09:57:00.003+05:30

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.

libcli - a cli core library

2009-03-31T15:26:00.003+05:30

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.

Now it is moved to Code google site, you can the latest of libcli from this link.

Open source VPNs

2009-03-17T15:42:00.003+05:30

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:

OpenVPN project:

QNX operating system - open source.

2009-03-16T18:57:00.003+05:30

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,

Linux based x86 routers, now competing the commercial market.

2009-03-15T11:24:00.003+05:30

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.

eCos -3.0 beta1

2009-02-26T06:23:00.002+05:30

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.

Git - a distributed scm evolved from linux kernel people.

2009-02-26T06:16:00.005+05:30

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.

Zigbee - open source project

2008-12-28T18:17:00.002+05:30

Actually, i came to know when i worked on the initial standard implementation, during the Aug 2004- Feb 2005 period, about this low power wpan network technology and its name.

While reading at that time i understood its still under evolving (sensor) technology, can have many applications around it. And also after the standard became public in the year 2005 mid, started thinking of to have open source stack, and tried several projects like linux-802-15-4,etc to participate into them. But that does't gone to a shape.

And also several other projects, like openbee.org etc started aggressively, but later i checked still they are like in the same state only.

Now i found one good project which is of open source (GPL2, and BSD) licensed. It is freakz stack. And complete information blog also on zigbee.

you can get all the information from this site.

Google Chrome

2008-09-02T08:22:00.006+05:30

Yes, this is a new work from Google. It is a web browser, and is of open source project, according to google's blog. I am eagerly waiting for its announcement on this Tuesday(Now in India it is Tuesday, Probably by night, ie. on US it will be Tuesday), can expect the news.

Actually am using now, Safari from Apple. It is a bit fast enough. It is having private browsing. Now the Microsoft has come with the idea, and promoting it, in its IE8. The good thing is, one can best use it for their personal browsing, R&D topics etc, rather negative way of using.

And next best am using Firefox 3.x. Let me see, the chrome affect, whether it will be the default browser on my Laptop.

Just cool

2008-08-01T07:53:00.003+05:30

I mean, the title should be spelled, Just Cuil. Cuil(http://www.cuil.com), is a new search engine launched, just in the last week. Its search results also ok. Still not on par to the Google which i like at this point. I heard the google name around 1999 in the same way, but today it is the starting site daily.

I just tried to search about one of my interested album, Spin doctros - two princes. I forgot the name and searched as doctors album, it came as 2nd entry in Google, and also quickly clearly in the cuil as Mp3 specific findings in the 1st page itself.

Probably have to wait and see, will this could become as default on some day.

There are so many other search engines, to know about them and their specialities

Napkin PC

2008-06-19T22:28:00.003+05:30

While browsing Net, i came across the Napkin PC.

Actually this is the 1st prize winner in the next generation competition for 2007-2008. Its so great thought come to him, even though we all see paper napkins in the restaurants, or other places etc, but we never thought in that way that such a device is possible. It's really good and great design work.

Basically, this PC does have an electronic e-Paper, on which the electronic pen is writing or sketching and will be interfaced to main computer using an RF device. An user can have several napkins for different pieces of information sketching. And finally he can integrate them into different combinations. I think, it would be more useful for creative and advertisement area people.

You can see more information from here.

Blogging

2008-06-15T14:34:00.004+05:30

In the past i never used the facility of blogging, as having an gmail account. Today through OpenID (openid.net), came to know that, the blog site can be used as an OpenId.

Thinking of the blog platform, that to write about some of my interests in Linux, Telecom, etc technologies and its products, of my readings on the net.
