Problem with Reliance ISP in Linux
by Chirag Arjun Bhangale 14 Sep '04

14 Sep '04

Hi Whenever I connect to the Internet from my reliance phone in Linux(FC2) and log on to site www.indianrail.gov.in i always get an error - Request Time Out. So I use a public proxy server (currently - 203.199.85.2:3128) and then get access to the site. However when i connect to the Internet from reliance phone in Windows I do not need a proxy server for the same site. What could be the reason? And how can i inform the reliance ISP about this problem? Moreover I ve observed that the site shows time-out for all foreign proxy servers. So I guess they ve blocked foreign servers. But then why such a weird problem with Reliance ISP?? Regards Chirag.

Hmm WOW, Embdeded Linux did stir up interest in a lot of ppl, but guys ....... be careful lest this also becomes one of those issues wher= e we discuss alot, but don;t take any concrete steps....

If u distribute any gpld software, u cannot place any restrictions except those that are already placed by the original software. Even if u r DARPA. In short if u distribute linux then it can be used for any purpose including commercial. And embedded linux was available since 1998. Maybe DARPA woke up from their catatonic slumber recently. http://www.uclinux.org/ "The first port of Linux to systems without a MMU was done during the last week of January, 1998 by Kenneth Albanowski and D. Jeff Dionne. As with all ports of Linux, this is free software under the GNU Public License. The first public target for this MMU-less port of Linux was demonstrated on a Palm PDA." Say Hello to the real world ;-).

[ILUG-BOM] Where is the best MS-Windows Vs LINUX Comparision Chart available
by Mahesh Mumbai 14 Sep '04

14 Sep '04

Dear Frieds Where can I download the Best Windows Vs Linux Comparision Chart available. This chart can change the mindset of the Account Department of any company which is costing them for TCO (Total Cost of Ownership) of Software. This chart can probably change the mindset of the traditional MS-Windows User. Regards Mahesh

I used to guide college projects, but found that too much spoon feeding was involved, as very few had an aptitude for engineering and problem solving in particular. It resulted in my doing the thinking and problem solving (otherwise the students would have not been able to complete the project).

Off the shelf components are atleast 30 times more expensive. Except for the system controller which can be an EPIAM2 mobo available locally, all circuits are quite simple. However The EPIAM2 is a power hog compared to ARM and would require a hefty power pack. or be powered from mains. > The cost of time is an investment in knowledge so it can be > discounted at the moment. > > Tell me if you want to do something with this.

Ok so what robot do we want? exterminator which will track someone and shoot? or house help like vaccum the floor.

Man we could setup one at VT / Thane / Borivali / Churchgate with a nice finger print reader. sms from the train qty of chappati. Go to RoboChap stick finger in out rolls al foil wrapped perfectly cooked chappatis. And we can patent this and we can rule the chappati world and we can be filthy rich and we need not eat chappati from our robots any more and .... Seriously tho the chappati making robot will work perfectly with an 8 bit micro and proper mechanics no os inside. So that would be boring.

I am not in this space so I may be off here, but I think that the issue here will be availability of the components, multi layered boards, etc. Designing custom hardware and getting a board built will be very time consuming unless you are working in some company or know people providing such service. It may be a better idea to try and acquire some SBC and try to port Linux on it. Then getting development tools like Emulators/BDM/JTAG debuggers is going to be another issue unless you already have something at hand. The point being, that doing embedded software on custom hardware involves a lot of supporting material and this is the main deterrent to its growth as a hobby. >It is a pity that even with tools like GNU/Linux and mediums like the >internet and email our level of education and awareness has become so pathetic. >Jeez here i go again like an old foggy. >I am personally interested in robotics.

Unfortunately, the mechanical and the electronic design is way beyond my skills. Software is something that I can do though. I have been thinking of implemented something like <http://protowrxs.com/nolen/robotics/LTBot/default.asp> or <http://www.evolution.com/er1/what_overview.masn> using standard hardware rather than creating a custom board for it. Should be simpler. Controller cards are available or can be designed for stepper motor control, etc. Cost of the project components is an issue. The cost of time is an investment in knowledge so it can be discounted at the moment. Tell me if you want to do something with this. Regards, Rajesh
