Data compression draws heavily from information theory, … [View More]

Simputer
by Vickram Crishna 01 Jul '01

01 Jul '01

I have been browsing thru the debate on Simputer, and am curious about some of the directions this has taken. The product is an Open Source hardware project, which has naturally used the Open Source approach to its software development as well. The IISc has undertaken the devlopment, with the active cooperation of many others. Now that it has reached the kickoff stage, it is possible to reach out and commercialise the production. So Encore (as I understand from the mails, I do not recall … [View More]

Now now Sameer, there you go again... Have you ever worked on a handheld? I too probably wouldn't have except for a rich friend of mine. What do you think would it mean by a rudimentary input system? Do you think just by placing a few taps you can access any data? For accessing data, you need to place queries, and queries need explicit search parameters, how do you suppose that can be achieved? >>the best of technology companies like Apple, Palm and a few Russian >>(who pioneered it) companies have tried and failed miserably. > So WHAT? Even the GNU people were unable to create a kernel for their > system until a University student from Finland came along ... Again, Sameer, have you ever thought about how handwritting recognition works? Have you thought or tried to code a handwriting recognition interface? Do you know how difficult it is? Or rather do you know a simple character like "A" can be written in more styles than one by multiple people with different personality types? That "A" is just from the Roman script, have you thought the complexity of deciphering any of the Indian scripts (I would consider Devnagari to be the simplest). >>Have you figured out the BOM of the Simputer? > I have to confess absolute ignorance in this regard!

Now what do _you_ think is the concept of a "computer"? As you mentioned that "They are trying to use technology to help people in a way comfortable to them", that is exactly what _Human Computer Interaction_ is all about... So we cannot keep back all our presumptions about Human Computer Interaction... > I had always hoped to get close to the Simputer project if I had been able > to get into the IISc for my post-graduation; but I guess that won't be > happening now! If you hoped to get to IISc, well thats good, thats a neat place with lot of facilities... But if you hoped to get close to the Simputer project, forget it, its not worth it... Just a bunch of techies don't make great computing devices, for that you need to have experts on HCI and somebody with a clear vision about what is to be done. Warm Regards, ~Mayuresh [View Less]

Zen, network topology, and Linux.
by Satya 30 Jun '01

30 Jun '01

Hypothetically... I have a DSL connection to the World. A hub is plugged into it, and 2-6 computers into the hub. Naturally, the computers have a class C (?) between them, which should not be routable from the World. The computers have their own connection to the World through the hub and DSL. I think the whole thing is a star topology, at least for the internal network. Is what I have described above correct, and possible? I suppose ideally, one of the Linux boxen would get the DSL line and … [View More]
