..like audio and video. Perhaps you could make clients close to the source receive most packets, but we, here, in the south of Brazil, would get only a few packets, since most of the data would be dropped on congested routers. If the server would try to compensate for this by resending some packets to each client who requested, then it is just easier to make unicast connections.
Multicast is ok to Audio and Video, but not ok to connection oriented stuff.
Will I be able to upgrade by upgrading the flash in the modem? I guess this is possible, but this will not be an option for "monetary" reasons..
And if the uplink connection can go as high as 48kbps, isn't it possible to connect now two regular modems at higher speeds, like some upgrade of v.34+?
And when the modem interrupts because there is an incoming call, how will it signal to the OS? Perhaps it will be transparent, the connection just stops sending/receiving data while you are talking, but then our pppds should not be any timeouts..
I don see why can't you use PVM or MPI or other message passing systems on FreeBSD to run a cluster with BSDs.
You just have to set the machines to allow rsh (os better, ssh) connections,./configure && make && make install lam, for instance, and lamboot your cluster.
(I'm just suggesting lam because it is what I've been playing with, but you can use any other system).
There is nothing special about linux. A good parallel system should be independent of plataform, right?

R.I.P. Iridium

· Score: 1
If you take a look at http://www.wired.com/wired/arc hive/6.10/iridium.html you will see that Iridium was not designed by bureaucrats, but by hackers. Too bad it was a hack with no commercial success. It's easy to talk how bad the system is, but please consider that 1. the idea of global communications was not so common in the design days as they are today, and 2. these are the guys to first suggest, and more important, build a system like that. They had the dream, they got the money, they built it. That's why I'm sad to hear of the failure of Iridium. Great hack value.
I heard Bob Cringely suggesting that Iridium would be a great buy, because the big bucks, those necessary to put the sattelites in orbit, were already spent, and that the money that you could get from the service would be interesting:)
I think the first thing you should check is lex & yacc. For what you are interested they seem to be ok. There is the "Lex & Yacc" book, cited in other comments, which is a good introduction to these tools, and introduce concepts you would learn in a "formal" class, like languages, grammars, etc. You should take a look.
For their lobby in extending copyrights. Copyrights were supposed to encourage artists to make profit from their art. I think Disney has already done enough profit with Mickey & friends. C'mon, Mickey is with us for as long as I can remember. It is obviously public domain.
How will I use BT in my notebook, will it be available PCMCIA adapters to use BT? Also, on the wireless topic, how is BT different than IEEE 802.11 (wireless LAN)? Ah, Can I use to PCMCIA 802.11 cards to connect one with the other directly, or do I need two access points to a wired net? Also, how come I've seen 128bit encryption lucent cards here in Brazil? Weren't they supposed to be not exportable?
It says: "The public administration, in all levels, the Powers of the Republic, the state companies and mixed economy companies, and all other public or private business under control of the brazilian society become obliged to use, preferentialy free software, free of proprietary restriction on availability, alteration and distribution in their software systems".
In our public university, the witch hunt has began. Last month, there was a big shift of operating systems on machines. A lot of machines changed from NT to Linux. Our lab, was the only which used mostly linux for research, and so we gave a lot of support to the other people. It was a lot of work, but we did meet a lot of new people.:)
Sorry for the bad translation of the law, but I hope you can get the idea.
Once I heard about a system that you would walk over a small area of small spheres, which, depending on how they roll would signal a direction to the VR environment. Apparently, it was very hard to walk over it, unless you were trained. I believe that if the body of the person was fixed, that would solve many problems. Anyone else has heard of this system?
I think a much more important thing we should focus is on ipp. I read the RFC, and am not sure if things are being done right. For instance, if you send a postscript job to the printer, it will have inline information about color, media size, simplex or duplex printing.. How will the printer decide if it uses the data on the ps stream or given to the ipp server? also, why should people on win32 machnes have to download and install a printer driver? couldn't windows/macs/unix produce a generic file, whithout the information set via ipp, and send it gzipped to the printer?
Also, could someone point me to a link which describes the win32 printing system? How does applications send data to the printer driver? Is it a generic format? If so, couldn't this data be passed over the network to a remote printer driver?
I think there is too much things to be improved in this area.. but my knowledge on printing systems is close to null..
As a brazilian, I would like to share with you my opinions on the subject.
In Brazil, there was a boom in the media about Linux, specially because of a company called Conectiva wich sells a translated and adapted version of RedHat Linux. This company has grown a lot and fast. Now, you can buy Linux in any bookstore, software shop, etc.
This caused a *lot* of people to start using Linux, which is great, but this people don't have the habit of reading to much.
Conectiva supports 2 mailing lists, ldp-br, lie-br, which discuss and work on translation of HOW-TOs, man pages and on internationalization of software. I subscribe to them, and every now and then there is a guy asking how to configure his modem and such. Sometimes, I think if it really is worthy to translate documentation to these people. But then I wait, and don't think anymore about it, and keep working!:)
To conclude, there are a lot of documentation out there, and these people just don't like to read. They don't like to translate also. They expect that a big company will guide them by the hand.
As a friend of mine says, when someone switches from Windows to Linux, they are switching from a slingshot to a canon. And a canon can be very nasty if yu don't know how to handle it.
I think it's time we start saying "Is it OSI certified?" when companies come up with "open source" licenses.
I like the following definition to open source licenses: "It is opensouce when they chmod a+rw the source code, not when they chmod a+r it".. Well, actually, it is a license which encourages the w bit.
Whenever the mainstream media talks about Linux, they talk about Linus, forgeting all the people behind it. How is it to be behind Linus shadow? Are you doing this just for a better world, or also for the fame, fortune and chicks?:) How do you see the future when Linus gets tired, and the revolution is in your hands?
I believe the great problem we will have to deal is that by analogy with the real world, individual certificates and keys are a right in the digital age. The same way you don't have to "buy" your signature, you shouldn't need to pay for a certifying agency to have your digital identity. I'm not quite sure how this problem should be approached. Perhaps the government should issue certificates to it's people, but of course this is hard to the government and big bussiness for companies. Otherwise, privacy will be exclusive of the "have"s while the "have not"s will have no access to crypto and digital security in general.
In The Dragons of Eden, Sagan tells how his "informant" become aware of the presence of a "silent watcher" after using pot. I remember when I read that I thought the report of the experience was so vivid that it should have been himself. But he also said that marijuana couldn't improve one's capability of understanding philosofy, for instance, so it should "suppress the left emisphere and let the stars to come out".
What I remember from "Life with UNIX: A guide for everyone" is that they didn't know by the time that software patents were possible, so he registered the patent (of the setUID mechanism) as an analogous hardware device.

so they can give to the artists who are being ripped off by the pirates..
And why use MP3, when you can use <a href="http://www.vorbis.org/">Ogg Vorbis</a>?

Is the Peter Deutsch of the book the same mentioned in the documentation of Ghost Script?

Of course, it's the use that make them evil, but guns are supposed to hurt people. So, what's the fun of it?
There is at least 2 brazilian distributions which are in Portuguese, and the documentation usually is acceptable

You should short the jumper that receives the signal from the case's power button.

No, it confuses Brazilians.. :)
