What Is Bittorrent?

Our friends at New AIDS Review recently wrote to ask what a torrent is and how one downloads one. To strip it down to its bare bones, bittorrent is a common form of file sharing. When you have a very large file and not a lot of server space or bandwidth to spare to distribute it to a lot of people, you set up a "torrent." Multiple people can act as "seeds" at once to distribute the load, and in fact even as you're downloading the file, you will start automatically, in the background, sharing that part of the file you've already downloaded with others.

Torrents are often used for semi-legal or even illegal file sharing. They're frankly a popular way to swap movies and music. But they can be used for entirely legitimate purposes whenever you have any large amount of data you want to distribute economically.

The torrent software I most recommend is AZEREUS--click here to download. It's the most user-friendly I've found. But if you Google you'll find many others.

Once you have it, to begin participating in a torrent you just click on a link provided for one. Here is the link again for the Duesberg/Bialy torrent, for any who wish to try it.

Dean - I just came across a roundup of bit torrent clients. The conclusion of the article was that (micro)torrent is the best. They are at utorrent.com.

I've used Azureus and it's ok. I now use Bit Tornado, which is a single window per torrent client. I like it much better than azureus.

Dean,

Thanks for making the Duesberg/Bialy torrent available.

I am attached to BitComet personally. Easy to use for noobs and enough feature for the torrent geeks.

One of the more popular examples is the new release of a software update. Could be a game, or a new kernel release for Linux, or any other large chunk of data.

If the release time is known, what will happen is that everyone on the planet will hit the server NOW, whereupon the server chokes, and no one can get the file.

Torrents were designed with that issue in mind. In fact, with torrents, more people accessing the file means faster downloads! It sounds counter-intuitive, but that's how it works, since a larger number of downloaders means a larger pool wherein you may find bits you haven't downloaded yet.

Writing this, it occurs to me that torrents are the first true internet-based file-sharing protocol. A torrent is widely distributed, highly redundant, and the loss of any given node has little effect on the network, since one may "re-route" data block requests merely by getting them from another node.

I have quoted the post below in several discussions about the content of this particular torrent, here at DW and elsewhere on the web. Since it seems that most of the people commenting now are highly computer literate, but not necessarily conversant with the material or the intended use of the actual download of the stream, I would like to place it here as well:

I actually have been in possession of the said CD since 1996 (courtesy of HB) and have circulated it to a few orthodox but relatively open-minded colleagues (we could call them jesuits of science) and students here and there. I have thoroughly read (and re-read) it and laughed heartily at some of Duesberg's marginal comments on the papers he CAREFULLY READ, my favorite being the one on mathematical models of the aids epidemic talking about the use of math in the absence of data: "cute" was his comment. Check some of them out when you have the time, but keep in mind what Igancio Ramonet concluded in his excellent book "La tyrannie de la communication": "S'informer fatigue" - informing oneself is tiresome. Don't expect predigested notions: if you REALLY want to know, and you have doubts about the relayers of info, go to the sources, which is exactly what you'll find in Harvey's CD. But, of course, if you lack stamina to actually read the info on which knowledge is based, then stick to reviews of your preferred stance. An amazing tool, but only if people actually use it.

Just remember what Sir Charles Babbage commented, long ago, on scientific fraud ("Reflections on the Decline of Science in England", 1830), which can be boiled down to three major forms of lying:

Trimming, which consists in the smoothing of irregularities to make the data look extremely accurate and precise.

Cooking, which refers to the practice of retaining only those results that fit the theory and discarding others that may weaken/limit its range of application (generalizability).

Forging, which means inventing some or all of the research data that are reported, and even reporting experiments to obtain those data that were never performed.

You decide, folks,

P.S.
Casey,

You are a perfect example of someone with specialized knowledge in one field that makes a terrific point in another one, and one this exactly related to the contents of the torrent when you write

A torrent is widely distributed, highly redundant, and the loss of any given node has little effect on the network, since one may "re-route" data block requests merely by getting them from another node.

Metabolic networks share exactly the same properties. This is very precisely why a mutation in any gene cannot cause cancer.

And less precisely derived, but also spot on, why HIV cannot possibly kill millions of cells it never even infects.

Csey, and anyone else interested in my comments above.

Go here and thenif you want the real beef go here

I would really like to carry on this conversation but unfortunately today is one of the few times I need be far away from a terminal all day.

But Casey, I will check much later in the tardes to see if you have written me.

Saludos todos, y un muy buen dia a todos tambien

So, How secure is the software? Does it only have access to previously downloaded files? Certain Folders?

The original bittorrent I have no idea about because it's so bare-bones it doesn't even have a GUI, it just sort of runs in the background and detects when you've clicked on a torrent and downloads it wherever it wants.

The version I use, Azerus, has a fairly normal interface where you tell it what to download, where to put it, when and where to stop, etc.

Well, I have Azureus running, and the Duesberg file downloaded and ready to go, but at the moment there are no takers. Not to worry. I live to serve, and my PC runs 24/7 to serve SETI@Home anyway.

It wasn't all that easy to find the Windows exe setup file for Azureus, by the way. It's there if you poke around. Here's the URL:

I'm the guy hosting the tracker, by the way, and occasionally my machine goes down (I had a brief power outage yesterday morning, for example). But I do always put it back up as soon as I'm able. I currently plan to run the tracker through the end of 2005. So if you start the torrent and it can't contact the tracker, just leave your client up and it'll start eventually.

Bill Dooley:
Update: since my last post, Azureus has managed to upload 9.3 MB of the 224 MB Duesberg file, to person or persons unknown, but now, again, there's no action. It's waiting.

This is not a complaint, merely an observation.

Now the hard part. I have to unZip the thing and begin reading. My head hurts already.
