Users of P2P networks who distribute files over a network can be identified by using Inernet Protocol ("IP") addresses....

this is incorrect as we will see; a there are many reasons why a user will not map to a particular IP address including the fact that most modern computers allow more than one user at a time (e.g. Windows and Macintosh "fast user switching" which was copied from FreeBSD via Linux)

because the unique IP address of the computer offering the files for distribution can be captured by another user during a search or file transfer.

some peer to peer systems, such as tor, sponsored by the US gouvernment and designed to allow freedom of speech in oppressive countries deliberately ensure that the IP address of the system connecting is different from the IP address of the system actually providing content. That is also true of freenet.

Users of P2P networks can be identifyed by their IP addresses because each computer or network device (such as a router) that connects to a P2P network

a router, almost by definition, does not directly connect to a P2P network.

must have a unique IP address within the Internet to deliver files from one computer or network device to another

This is an attempt to worm around the existence of NAT by claiming that it is the NAT device which is making the connnection to the network. Probably the intent is to say that the owner of the NAT device is responsible, however, it is not practical or possible to track connections on a NAT device simply because the level of logging generated is massive since it can be as many as several log writings per second per user when the user is e.g. downloading an HTTP page containing links to many images.

Two computers cannot effectively function if they are connected to the Internet with the same IP address at the same time.

Apart from NAT, there is another way in which a device can share an IP address with another system. Special software such as ettercap exists which is designed to allow a system to use the IP address of another system and even modify outgoing connections from the address of the other system. There is no practical way for any normal organisation to guarantee that this is not going on and even a government level organisation would require considerable resources to do so.

This is analogous to the telephone system where each location has a unique number

This analogy is very good. In the phone system we have things like "call centres" where many people have the same number (NAT) and we are also able to use someone elses number by connecting our phone to their line outside their house. In the phone system I could even create a phone which rings with your number with very little difficulty. That is exactly like IP.

For example in a particular home, there may be three or four different telephones, but only one call can be placed at the same time to or from this phone

Not only is this wrong since ISDN phones support multiple lines (two is standard) but this is a point where the telephone to IP analogy breaks down since there are special numbers (TCP and UDP port numbers) which allow multiple connections to be connected to the same IP address. A typical example of this is that you can download two files at the same time.

These port numbers can be used by tools such as ettercap to initiate connections which use another computers IP address but will (almost) never interfere with the normal operation of that other computer.

• Detect when an unofficial package gets an official version.
• Detect when a package with a custom build is removed from the remote tree.

And more stuff. Like I said, slackpkg on steroids. It's much faster, uses less bandwidth, detects more events and it's probably more flexible. I'm pretty satisfied with the result, so I wanted to invite people to read the program's webpage and try it if you think you fall into the target audience. It would be fine if I was the only user, but more eyes mean less bugs and I think it's always a shame when you create a tool which you are proud of and SourceForge only shows 20 downloads because people do not actually know it exists. Its main problem is that the initial setup may be more complex than usual and you need to read a bit more to know how it works. Howev

There is exactly one way this could work, and it will limit flexibility to a large degree, and it's doesn't sound like it's what they're doing. Also, that one way won't work:

Hardware signs all of the input, which is transferred verbatim (or equivilant) to the server, which checks the signature *and uses that exact input* for game input.

And that won't work. Here's why: http://opnrzr.sourceforge.net/

The Razer Copperhead is readily available and easily modified to incorporate any aimbot you want. Just tell the mouse (either via USB, or if Intel's smart enough to check that, one of the mouse's other inputs) what to send, and have it send it.

There are other mice with modifyable firmware, keyboards with modifyable firmware, and you can get generic USB hardware like the hardware in the Razer Copperhead and make it in to whatever you want. The Copperhead itself can act as many different USB input devices, and does act as both a mouse and keyboard with default firmware.

What would really revolutionize computing and laptops in general is affordable mouse compatible touchscreens. It gets tedious to drag finger on an alps all day long. --chris http://nxdos.sourceforge.net/

Strigi is a fast and good search program, and it will be part of KDE 4 (it's still desktop-neutral, however). There's also Beagle which supports more file formats and whatnot, but it requires mono (C#) to run and is a bit of a resource hog.

However, this does look like an active project: http://sourceforge.net/projects/sync4jmozilla/

One of PopCap's best-known games, Dynomite, is a direct ripoff of Taito's Puzzle Bobble, one of the best-known (and -loved) puzzle games of all time.

PopCap can stick their whining about ripoffs right up their hypocritical, untalented asses.

One of the most egregious game rip-offs I've seen in commercial gaming is the shareware game 'Snood', another direct rip off of Puzzle Bobble. And not only was Snood collecting shareware donations, they actually had a GameBoy version!

I think the amount of cash you have available to spend on lawyers is a factor, as I've never seen game clones of Monopoly and so on.

Because slocate only searches in the file names of files and has to update its database periodically (the latter can be remedied with rlocate), while things like Google Desktop search, Beagle, etc. search inside the files' contents and metadata as well as the names, update themselves in real time, and can show you matches from multiple sources in one place (search results from files, emails, address book, etc.)

Not the actual CSS which is, with five minutes of practice, very easy to use. Much better than tables all over the place. The headache comes from IE dang 6 and below.

Since I can't legally test in IE6 (no Windows license, and browsershots.org takes a 4 hour round trip for Windows screenshots) making IE6 specific tweaks is a pain in the backside. I'll finish up eventually I'm sure, in the mean time I plan to just turn off CSS for those users.

As a side note CSSED is really nice for those of you who like editing their CSS by hand.

Google Search for "ODF file". Every single link appears to be relevant.

In particular, I draw your attention to the fourth item down: ODF Converter Add-ins for Offce - a 1.6MB plugin which allows both opening and saving ODF files in Office.

Let's start with a Slashdotting of NASA...

• Scalable Dynamic Chimera Methods for Unsteady Aerodynamics is one of those packages mere mortals like us will have either no use for or will have to just drool over.
• Fully Unstructured Navier-Stokes 3D is a nice Fortran-based CFD, requires some hefty paperwork to obtain, and may need you to use G95 rather than GCC's GFortran, due to compiler bugs.
• OVERFLOW and related CFD software.
• Three Dimensional Multi-block Advanced Grid Generation System is the component that actually lets you do a lot of the necessary grid work for CFDs.
• Viscous Upwind ALgorithm for Complex Flow ANalysis is the hardest of the CFD codes at NASA to obtain, but if you want to work on anything hypersonic, it's the best place to start. Do Not Use hypersonic airflows for CPU cooling.

• Astrophysical Thermonuclear Flash Simulator - well, you never know.
• Geant4, for the subatomic nuclear physicist in your life...
• Open Field Operation and Manipulation is a nice open-source CFD package.
• Parallel Basic Local Alignment Search Tool gives you a parallelized search engine for nucleotides and proteins.
• Stanford Exploration Project provides some nice parallel geophysics applications and tools.
• Tachyon Parallel Raytracer is a nice example of what you can do with parallelism and graphics.

• Kerrighed is an up-and-coming clustering system for Linux. I saw it demonstrated at SC|05 - and was less than impressed. It needed a lot of work at that point. However, it looks like it has improved a lot since then, and it would be unreasonable to not mention it.
• MOSIX is the second-oldest clustering technology to gain a fan following to rival Star Trek. It's very good, though hard to get if you're not in academia. Arguably for entirely fair reasons.
• OpenMOSIX was originally a fork from MOSIX but is now essentially its own clustering technology. Development is nowhere near the speed I'd like, it does need far more eyes, but is well-known and highly regarded. Moshe Bar is also one of the coolest developers I've encountered.

• DAKOTA is a program for profiling parallel applications and should be useful in telling you where you are gaining and losing.
• HPC Toolkit is another toolkit for profiling HPC applications.
• is yet another profiler for parallel software. Between this and the others I've listed, you should have more information than sequential programmers ever get to work with.
• Performance API is a facility used by most of the profiling software to provide an architecture-independent view of performance counters. I have it on good authority that some (now former)

GPLed opensource product that institute DRM. It went something like a ssha encryption of the binary content and the provider generated an encrypted key based on your key which was based on your account information(from the provider). Then whatever player you were using needed a plugin that used another program to decrypt the media and stream it into the player.

Just to follow on your example, in such a system, the plugin would probably have to be a closed-source binary blob, or else you could just modify it to intercept and spit out the decryption key as it was being received from the provider. (I'm not trying to personally attack you -- what you created there was as good a DRM system as most of the real ones on the market, but it's running into the fundamental limitation of DRM.) It's all smoke and mirrors.

Anyway, after doing a little Googling, I think the "open source DRM" thing a while back was related to someone on the Gstreamer project discussing adding support for DRMed formats -- but it's still not clear how they'd accomplish that. Some people have pointed towards Sun's drm-opera project as one possible avenue, but AFAIK that's nothing but vaporware, and it too was widely criticized as being impossible when Jonathan Schwartz announced it. According to this article there have been two past attempts to create "open source DRM": one was OpenIPMP in 2002, another was Media-S, more recently.

OpenIPMP has a SourceForge project page, although the latest update was a year ago. Apparently there's some code that can be downloaded, but aside from that they are cagey on how it works, and heavy on buzzwords. Nothing about it makes me suspect that they have really discovered anything huge (and a DRM system that didn't rely on obscurity would be pretty huge). If anyone is familiar with the project and wants to comment, I'm genuinely curious.

Media-S apparently evolved out of an effort to make a "Secure OGG" format. They at least have an FAQ. Basically, they're going for the straightforward 'binary blob' route:

If Media-S is open source, how can the encryption be secure?

If a company wishes to use Media-S to protect their content, SideSpace Solutions highly recommends purchasing a binary distribution license. Under this license, any modifications to Media-S (such as a change of encryption engine or pri

Here we are at two topics that I'm very interested in: The American class system and social networking. The first because of my politics, and my own constantly shifting class background. The second because of my work on Appleseed, an open source social networking web software that uses an open, distributed model.

I have a number of serious issues with this analysis, not the least of which is the idea that social capital is more important than actual capital in determining class relationship. While I grant that social capital is very important, to say that it is more important is to fail to recognize that income and benefits will greatly affect social capital over a lifetime. So, while that $14k a year barrista who reads Engels and hangs out with upper middle class intellectuals may not be working class because they're set to inherit a million dollars from their parents when they're 30, they may just as well be from a trailer park or a rundown city block and simply enjoy reading German anti-capitalist literature. As their life goes on, the experiences they have in relation to the experiences of those who were born middle or upper class will diverge. In many ways, college will become an abheration as the reality of student loans and possibly medical bills and other situations in which non-familial social capital can be pretty useless, sets in.

And as the poster above pointed out, the discussion about class in this greater essay falls into a common trap that, oddly enough, many anti-capitalists fall into, which is the concept of essentialism. That people are defined by simplistic, singular ideas that represent them completely. This is why, in my opinion, bodies of work such as Critical Race Theory have some of the best analysis of the American class system, because it wholesale rejects essentialism as a unified method of categorization.

I also find the lack of analysis of how these walled gardens affect the social relationships to be disappointing. This might even be the best approach to such an essay, since Facebook in many ways represents a "gated community" which has just recently opened to the public. Myspace, for better or worse, represents the seemingly common space, not-so-secretly owned by private interests.

How a distributed, open source social networking system will affect these networks is something that (at this point) can only be hypothesized (given that the Appleseed network is only a few dozen sites at this point), but at some point this will change, and social networking will become like email, interconnecting between servers easily. This allows great potential for sociological and anthropological studies which, I think, will more closely follow society itself.

Or maybe it won't. Maybe it will reflect it's population more than the society they come from. Maybe Myspace and Facebook, with it's privately owned "commons" and it's gated community with education and career requirements (respectively) is more representative of society than a distributed system would be.

I was thinking about this during a spell of RSI years ago and came up with this (weegie). It's almost usable, at least to the kind of person who'd consider learning Dvorak or a Twiddler. I'd love it if someone could figure out something better than our current keyboard/mouse arrangement.

I'm not sure this would work; GreaseMonkey only works *after* a page is loaded. What you need is your own web proxy, like proximodo, to do the fix before it gets to your browser.

Do what I did: start your own project. Instead of wading through the poorly-written source code of others, generate your own code. Find a niche that has not yet been filled, and just start writing. For me, it was an equivalent to Microsoft Paint on the Mac: there are absolutely none. So I sat down with a good Cocoa programming book, and just did what I could. Fifteen thousand downloads later, and my project has exceeded my wildest expectations. (Shameless self-plug)

specifically, this link. You may need an account to view it, I don't know.

Two words: Source. Forge. As in Sourceforge.net, the birthplace of countless OSS projects.

End of story. Go there, find something that's interesting, and if it's no longer in development, take it over or fork it, and if it's in development, see if you can join the team (if they need help, there is usually a "help wanted" link on the main project page). Most groups need help, and if you're competent, they'll be glad to have you.

If you're moving into a big team, be polite. You're a young programmer, and lots of young programmers have a lot of hubris. If you can't work with the people there (and this happens a lot; I once took a Java project, and simply updated it as it stood to get rid of depricated functions, almost no other changes, and I got flamed like you can't even imagine by the lone devloper who hadn't even released an update for 2 years) move on and do something else. There are so many projects, there is bound to be something awesome out there that you want to be a part of.

The Ubuntu Customization Kit (some old version here, with screenshots) looks useful, and Linux Live looks even more general.

It ain't Linux, but it's a very good piece of software that will do everything you want, and more.

Is there a comparison between TUGZip and 7-ZIP? (also see 7-zip.org)

I recently started a project over at sourceforge and I think that what they provide is really great. They give you all kinds of features like forums, news, trackers, and web site statistics via RSS. They will host a web site to promote your project. That hosting includes the ability to run a web application written in perl and access to your own database on a MySql server. With that much capability, I implemented the project web site using the source code of the project itself.

You also get ssh, sftp, and cvs (via ssh) access. I haven't run into any problems with updating the content. There is a web interface for downloading code but you have to use cvs for uploading. I don't know what problem the original poster was running into but I found no difficulties with it.

The one program I always download from SF is filezilla (client) and recently I set up the server version to replace the broken default IIS FTP server.
Both client and server are working great, highly recommended free open source FTP client and server.

Yeah, hardly interesting, especially when you consider that the way Sourceforge measures "activity" is slightly strange, and generally broken anyway. Have you ever heard of the five projects they mention? No, me neither.

They could have written a semi-decent article about some interesting projects, but they didn't.
