It will be well placed if you have some background in developing kernels for RTOS, etc. Not even writing applications on RTOS is enough to get into the kernel of such a beast leave aside knowing just the feature set. You may have seriously underestimated the effort involved in such an endeavour. That aside, the practical problem for such a project is getting the hardware information of the cell phone in question. Just knowing the processor is not enough, you need to know the memory map, the peripherals connected, etc. For connectivity you wil need to know the protocols, etc. Nokia is not encouraging anyone to develop any software for it's phones which use the Nokia OS (apart from using J2ME). You can develop C++ applications for Series 60 phones which use the Symbian OS but all the interesting APIs are not available. The OS abstracts all the details of the hardware and no hardware info is actually available for any Nokia phone AFAIK. Replacing the OS on such phones is going to be VERY difficult if not impossible. You can find technical info for any Nokia phone in the developer section of the website. If you want to play around with cell phones, the Motorola Linux phone seems to be the best bet since all the info will likely be available. All the best in your venture. Regards, Rajesh

Hello Latesh and Harsh, I am enthusiastic to put my efforts on an open-source project. When can we arrange a meeting and start things? There is an upcoming event for GLUG Mumbai on 12th September 2004 at IIT Bombay (KReSIT, 3rd Floor). Is it possible for you to meet on this day (Sunday)? Please reply on the mailing list or my email address (yogeshjshah(a)hotmail.com). Thank you and looking forward to hear from you. With regards, Yogesh _________________________________________________________________ Pep up your screen!

An Idea-2
by Rony Bill 10 Sep '04

10 Sep '04

Hello All, There were some queries about the idea which I hope to answer. The system of high speed serial data dumping that I wrote about will not replace the existing internet. It will only provide an extra ultra high speed channel for downloading heavy files for each one and everyone without the bother of bandwidth sharing and at a very affordable price. As a rule or plan, all files above 5 or 10 Mb can be considered eligible for this system. Entire web sites can be downloaded as a single arcihve file. The ones lower than that, can be downloaded using the normal internet. All peer-peer, VPN, chat, email, online registration, payments, shopping etc. will be done using *regular internet only*. This high speed channel will not only be usefull as an infotainment channel for music, news and video but also for normal software and other heavy file downloads. Suppose you need to download 4 CDs of Linux, totalling 4 x 700 Mb = 2800 Mb or 2.8 Gb in your home. Even at a speed of 512 Kbits per second, your speed in bytes will be 512 / 8 = 64 Kbytes per second. So 2800 Mb will take (2,800,000 Kb / 64) seconds = 43750 seconds. This translates to more than 12 Hours. So it takes approx. 3 hours per CD to download even at 512 Kbps which everyone still cannot afford yet or their locality does not have this facility. You also got to treat your cablewala as God. Instead of that, in the system suggested, the waiting time would be max. half an hour or one hour but 4 CDs would be downloaded in less than 3 seconds. Imagine the time saved for people who need to download CDs regularly and in large numbers. A single DVD of 4.3 Gb would be downloaded in 4.3 seconds. On the regular 512 Kbps it would take 18.66 Hours. All you would need to do is mark all the files to be downloaded from a pilot list and within their rotation cycle of half or one hour, they would all be dowloaded one by one and be ready in your hard disk in one cycle itself. The maximum you can download within this rotation cycle will only be limitted to the maximum capacity of your hdd. The same data would take days or weeks to download under normal net circumstances. 120 Gb takes more than 21 full days to download at 512 Kbps. In this case, half or one hour. Take your pick. Frankly I don't know what is latency in a satellite but if Philip could elaborate more and provide points on why it has a problem in sat transmission, it would help a lot in making improvements to this system. Since the repeat cycle of data broadcast is every hour or half, problems due to bad weather or earth's rotation will be temporary. Any modifications and suggestions are welcome too. The example I gave is for a 1 Gbytes per second speed having a capacity of 86.4 Terabytes per rotation cycle of half or one hour. This should suffice for all the heavy files that currently exist everywhere on the internet. If it is technologically possible, we can use much higher speeds like 2 to 5 GBytes per second and that will pack in multiples of 86.4 Terrabytes per cycle or reduce the cycle time for the same amount of data. Regards, Rony.

hello every1, i have been a newbee in linux & also on this = grp, i c lot of events and meetings being organised, but from = a newbeis point of view i would like to suggest u ppl to keep an semi= nar or a small workshop abt GNU/Linux....especially abt switching ont= o "Debian" from other linux distribution i mea= n the installation GUI of other distributions like RH & Mandrake = r very user friendly, but thats not the case with debian, and especia= lly for a newbee its very difficult. There are lot of guys out= there want to learn debian, unfortunately today in all classes they = teach RH, its like "Linux = RH", moreover there r very fe= w books or almost 'none' available in book stalls regarding debian, a= nd its not possible for all ppl to just log onto net and read ebooks. So i strongly feel that there shd be some event organised abt = starting/learning debian.....and other such isuues which could be = difficult for a newbee to configure on debian..I know that "Knoppix&qu= ot; could be a nice solution for this but still lets try to learn the typical debian way.... Pls send ur suggestions abt this= .... Thanku Anil M. Kulkarni = [1] [adstream=] References 1. 3D"http://clients.rediff.com/signat

Linux on Cell
by Latesh G 09 Sep '04

Hi Yogesh, Thanks for showin interest, I dont have practical knowledge about how to alter the kernel for Nokia but I have good knowledge about what features are available in particular phone(Nokia), what OS it has and what are its limitations also how we can enhance it. I know what kind of hardware is required for transffering stuff to Cell (not MMS n Tones it uses different Cable). I suppose if few enthusiasts show inetrest in this we can give it a try and I'm sure we can do it as nothings impossible. Latesh. Yahoo! India Matrimony: Find your life partneronline.

Linux Cell Phone
by Latesh G 09 Sep '04

09 Sep '04

Hi Guys, I have had really bad experience with Nokia that time I felt cant I jus make my own OS like (Symbian OS used in Series 60 cells) and load it on my cell. Cant few of us gather together and build our own OS for Cell phones, there lot we can do with cell. While on move I surf net via GPRS and when I find something useful I cant save it cause Nokia doesnt want me to save it when its possible. I try to transfer Images through Infra-Red but cant cause Nokia doesnt want me to. I can only transfer Contact which doesnt evn take 15secs if done manually. The possibilities are endless, cant we jus give it a go??? Regards, Latesh. Yahoo! India Matrimony: Find your life partneronline.
