Biological species converging is not that easy....
The definition of a species is when two subspecies are no longer capable of interbreeding. When you can't breed its kind of hard to converge. Two subspecies on the other hand can branch. but it would result in the same species.
What does happen is symbiosis, where two seperate species live together as one organism, but still as seperate species.
It can be done, but the same fundamental laws of nature also explain why the electricity grid is going to radiate like hell. In short it is possible, but not without pissing of everyboddy that is currently using the RF spectrum. The power grid was never ment for this...
Wasn't "There are 1001 different and incompatable linux versions/distributions" part of their FUD? Seems they didn't listen to themselves:)

No its about doing what you like. Programmers that write as a hobby (most FS programmers) should choose/create whatever they like. Don't try to force them unless you will pay them for it!
I used twm for years and only recently moved to ctwm because I like having more then one workspace... I don't want to use the other window managers because their philosophy doesn't match mine, and it probably never will. Another program to do almost the same thing isn't bad... just look at the amount of software available for windows, I bet there are 380 text editors for windows to. Just one is the default and most used. But that doesn't mean that the others don't have a right to exist.
Virtex-II pro is an FPGA so you can't really "port to it" - though the catch is that they comes with IBM's powerPC cores embedded. Why would he mention that he ported to Virtex-II pro instead of just PowerPC architecture?
Even stranger he mentioned there were going to be some anouncements later this QUARTER!!! Since he also said only linux ports need three months instead of three weeks they must be ditching netBSD and switching to linux:)
If you transmit a signal with a 2KHz bandwidth on a carrier using AM you get a transmission signal that is 4KHz width (the message is on each side of the carrier in two sidebands). However where you to use Single Side Band (Suppress the carrier and one sideband) You get a 2KHz RF signal. What is normally called AM has TWO sidebands and thus double the bandwidth of the message.
Try building some linear amplifiers that work for ALL frequencies..... You did? Next stop oscillators that work on ALL frequencies. Then an antenna system that works well on ALL frequencies.....
You are still left with a limited piece of the spectrum and in this piece you are still going to run out of space (either in the frequency domain or in the code word domain). Shannon's law still applies for the signal/noise ration.
Its not easy, remember you are trying to look at AND decipher a hundred different flashing lights. You can't decode all of them at the same time. Good hardware and software processing might do a bit better then you at this but even that has its upper limits.
Although nice in theory in most practical situations it just doesn't work. Think of satelite TV for instance, they use this method (multiple satelites transmitting on the same frequencies) and you need dishes that are very directional for it to work. The amount of processing needed to do something like this in e.g. a walkman is just not doable with current technology.
How do you know which is the right one? Asuming you didn't already know which way to look exactly (think roaming) You might be able to get that information from the messages they are sending, but then again if it were ten green lights you would have to read ten messages simultaniously. If you can do that imagin a hundred flashing green lights....
What the guy in the article is talking about is using spread spectrum techniques. This is done by spreading your signal over a large spectrum with a pseudo random key. The number of possible keys is still limited (There has to be a certain difference between two keys for it two work) and thus you still have a maximum number of users although things like roaming are a lot easier since you are limited by keys overlapping and not range overlapping.
This is what is being done in CDMA cellphones, Wireless Lan, Bluetooth etc. It is nothing new, already happening and you still need regulation to make sure the spectrum doesn't get completly unusable.
When you say that the people were opressed did you mean by the U.S.A. ?
Indirectly, YES.
The US has a reputation of supporting anybody that makes them money. i.e. the royal family of Saudi Arabia (home of a certain mr. Bin Laden), Saddam (Before he invaded another US supported oil state), the Sjah of Iran, Israel (Who has occupied palestinian territory for 40 years and violated more UN resolutions than Iraq). In all cases people are/were oppressed and fundamentalists offered a way out: go to heaven if you fight for a just cause against the big evil.
A lot of people in the western would agree that the US isn't know for having ethics in such cases (democracy and freedom appearantly are only important if you are a US citizen). It is not hard to see how somebody who grew up worse conditions would see it as plain evil instead of stupid.
It still doesn't justify terrorism but it sure explains why people do things like this. If the US was to threat people with respect (not exactly the capitalist way I know...) there would be far less terrorists.
They were neither justifyable or acceptable, but they doesn't justify or make acceptable the kneejerk reaction of invading EVERYBODYS privacy for some 'war on terrorism'
9-11 didn't happen because people had to much privacy...
It happened because people were opressed and somebody offered a way out (although arguably not the right way). That is were you have to change things. Preventing somebody from blowing himself up is done by taking away the need for such an act.
Librarys have version numbers look in/lib you will see you have several links to various version of a c library e.g. libc.so.6, libc.so.5. These point to the actual library. As long as a libraries API doesn't change between major versions (as it should) there is no problem.
Books are nice, but very subject specific. You also need some trees for them... When you compare how many books you can fill with a google search I think that internet connection isn't so expensive afterall.
The western world wasn't such a fun place to live in until education became available to everyboddy. You said yourself that you need skilled labour. Skilled labour means good education. For education to work you need to get people to look beyond their horizon into the world. What better medium than the internet to do this?
No it doesn't.... It is a differend solution to a different problem caused by the same thing....
The cause is the big cache in the modem, it results in a delay on outgoing traffic. One problem is that interactive traffic gets, well, less interactive (e.g. the echo characters in a remote shell have a delay). This is solved in the HOWTO you refered to. Another problem is that the downstream acks get delayed resulting in less downstream data. This is solved in the mentioned article.
A combination of the two would be really great and could probably be done in both linux and openbsd.

It says clearly in the article that vendors are allowed to make changes and distribute them.
That is forking no matter how small the change.

Speex is a voice codec used for low bandwidth voice data (ie voip).
Ogg is a container format, you can put speex data inside an ogg file.
You probably mean Vorbis, which is an general purpose audio codec much like mp3. Most of the time vorbis data is also put into ogg files.

Indeed most libraries have subversions, but most apps just link to the major version. When an app insists it needs version 6.3.2.4.33 it gets nasty...
Jeroen
Librarys have version numbers /lib you will see you have several links to various version of a c library e.g. libc.so.6, libc.so.5.

These point to the actual library.

For education to work you need to get people to look beyond their horizon into the world. What better medium than the internet to do this?
Jeroen
It is all very simple actually....
You can find practicly anything on the internet, no need for expensive books, all you need is a little curiousity.
As for fighting big business and governments all you need is to set up a 'poor-villages-against-whatever' mailinglist and you can organize.
That is the power of the internet: spreading information at practicly no cost.
Jeroen
So besides not reading the article (which seems to be standard on slashdot these days) you didn't even read past the subject line?
Even the little blurp on slashdot had enough information like the line that says that its a method to maximize both up and downstream...
