Follow these five easy steps and never see another Slashdot ad again:
- Go into your Homepage
Preferences.
- Scroll down to the "User Space" textarea, and paste the following four
lines of HTML in there:
(click here to download the adkiller javascript code and put it on your own webspace, in case you don't trust me
:-)
- Scroll down the list of slashboxes, and make sure the "User Space" checkbox (inexplicably located between "MP3.com" and "Myther.com") is checked.
- Return to the front page, and your Slashbox should be there, quietly zapping all iframes and banner-shaped images on the page.
- There is no step 5!! It's that easy.
There are a few problems, however:If you are a Javascript wizard and know how to make this script work on Opera or IE, please tell me. Ad-free Slashdot should be available to everyone!
Loneliness is a power that we possess to give or take away forever
I worry that things like freenet are going to make it so that people will have to engage in continual warfare with people like John Ashcroft.
Ashcroft is the guy who pulled lots of federal enviro data on pipeline locations and stuff from the Net. He will have to attack Google caches and stuff to completely hide this information.
Total lack of anonymity is next. How can Freenet survive if the service is branded as terrorist and the individual humans are pulled away from their terminals while servers are confiscated? No robustness of code can prevent this.
I love Freenet, but to protect anonymity we must acknowledge that not all solutions to civil liberties restrictions are code-based. We must back them up with aggressive defence of civil liberties in political and protest arenas.

A year or two ago there was a presentation at my college about Freenet. One of the CS guys here was "on the development team" (whatever that means). I never did hear a real reason, other than ideals, for doing it. (In fact the kid that was talking about it was mentioning an effort to try moving it onto packet radio, thus freeing it from even the censorship of ISPs. This threw a huge red flag for me that he didn't know what he was talking about: this is blatantly illegal by FCC regulations, and anyone who tries it will lose their ham license! No encryption is allowed, in any form whatsoever. You can't even legally come up with a substitution cypher, like "beans" means "meet me in the parking lot" and "chicken" means "9:30pm". NOTHING. And the encryption issue is just the tip of it. Read up on it, get your ham radio license, it'll be immediately clear that doing anything even remotely resembling this is just not feasible on the ham bands in the US.)
So yeah, I'm veering off-topic. Anyway. Let me reiterate: I'm not telling anyone NOT to do work on something they're devoted to. I do appreciate the ideals that Freenet stands for. But seriously, what's going to make it succeed? What makes it worth the horrible inefficiencies designed into the protocol? Is it actually useful to anyone? Alright, enough from me. I hope someone can answer these, I'm very curious. Somebody give me a reason to help the development effort!
The streets shall flow with the blood of the Guberminky.
... but why do they have to erect the toll gates first ? I was reading the ToS for an ISP hosted site with the thought of donating some of the capacity to freenet and they promised to:
- perv at (monitor activity) what I'm doing (item 1.3)
- refuse access at their discretion (item 2.8)
- pass on any liability due to fraudulent access (item3.5)
- censor any content deemed inappropriate (item 4.3);
- keep any left-over money paid in advance (item 5.2);
- and generally ask me trust them on any software they provide (item 6.4).
I know eternal vigilence is the price for freedom but it would be nice to nap a bit instead of continually maintaining your own system. Now if they can come up with a combo 802.11+freenet cache node and sell it, it might be a hit.

Or you could just browse with Lynx.
Like it or not, not everyone wants to use an ancient text browser with fixed-width fonts and no images or colours whatsoever. There is plenty of multimedia content on the Internet that is useful, not just banner ads.
Or use an ad-busting proxy.
This takes time to download and install the proxy software, set up your browser, and spend hours upon frustrating hours tuning Junkbuster to fit your needs. Not everyone is inclined to run a whole other piece of software just so they can browse without ads.
Or just ask daddy for a little extra money this week and pay the damn $5.
Cute, but don't you think it's just the slightest bit slimy and underhanded of VA to abuse their most popular asset (and that's all Slashdot is to VA, a cash cow) in order to annoy people into giving them money? Pissing off your users is NOT a valid business plan.
I used to love Slashdot too, but their newest money-making scheme quite frankly pisses me off. I'd much rather see Taco and Hemos throw in the towel than betray the ideals of freedom from corporate oppression that Slashdot once embodied. I hope that you will open your eyes and join me in showing them that we're not going to take it.

I've been running a node or two for several years now. There were once a large number of Freenet web sites, but when the protocol changed, most of them dissappeared. Now a lot of them are coming back. But who's to say the protocal won't change again in a few months, and we're back to square one. It seems to be a project with no plan and thus no endpoint. Imagine if Microsoft changed the format for Word files every 6 months, and you get the idea.
A free service to propogate spam - and this time there's no delete key!
Build stuff. Stuff that walks, stuff that rolls, whatever.
I put 8 months of hard work into Freenet - in particular, developing the W--dows FreeWeb client program and the multi-platform FCPtools library. It's very possible that I will return to the project at some time in the near future.
In my mind, Freenet is still very much in its infancy. At present, it's mostly a prototype, suffering severely from being written in J---, but if gcj gets into a fit state (or some hard-assed hackers re-code it in C), the major problems will be overcome.
But to me, one of Freenet's greatest strengths is almost totally unknown - the bottom layer is designed so that almost anything can be easily slotted in and used as a transport - not just plain TCP/stream sessions, but UDP, or tunnels, or anything.
Because of this design foresight, it's very straightforward to write and plug in a few steganographic transport drivers which traffic keys in devious ways, eg usenet groups with graphics file carriers, or whitespace/grammatical stego in plaintext mailing lists or IRC, hidden packets within webcam feeds, even pirate radio (note that Freenet is high on redundancy and very fault-tolerant).
The way I see it, any determined effort at stamping Freenet out will bring the project alive like never before, and cause it to attract legions of talented and inspired developers to keep n steps ahead in the arms race.

I think that all it would take is for a nice MP3-sharing program with quality indexing and searching to be deployed on top of freenet. As long as it had a nice interface and was easy to install, you could easily get a bunch of freenet nodes off of people who care little about free speech, but who care lots about free music.
Ya I know, I was getting too heated and prematurely ejactulated a post without previewing.

Excellent post, thank you very much! (I must admit, I'm not quite inspired to join the dev team, but.. ;) I very much appreciate your opinions, and your good examples. If only more of the posts on Slashdot were of this caliber. I am so tired of the "you're not good enough for Freenet, we don't want you" attitude I keep getting. (All from the ACs, unsurprisingly enough. ;) Why wouldn't they just answer my question instead of getting all defensive? You did! Thank you! Good post. :)

Thank you Jamie for bring this issue to the front.
Learn about the apostrophe smart guy.
Spammers pollute. Freenet appears to be designed to allow for maximum pollution per unit of legitimate content.
I'd prefer to be proven wrong about this, but it looks to me like the bad apples are going to spoil this barrel even more so than we saw with usenet.

Well then, if you dont like the SSSCA, the RIAA, the DCMA, and you want to challenge it, write applications which are impossible to stop.
Gnutella isnt enough, eventually Gnutella will be attacked in some way and people will need somewhere to go,when this happens freenet has to be ready.
We already have a frost front end, and freenewsreader, we have the FreeWeb, as far as having a napster like app for freenet, thats not going to happen, but you will be able to share files on freenet in complete safety.

I understand programmers can be esoteric. I took the chance to talk to some of them in IIRC, alot of them are cool. Certainly not as bad as the gnome programmers.
Anyhow, Why sould you develop for freenet? I'll tell you why, because you'll be helping a great deal of people, millions in fact, including yourself. Theres many reasons to use freenet, free storage for the masses is the most obvious reason. Webpages wont cost a dime anymore using freenet So you and many others would save money.
Popular websites would never be taken down, the more popular it is the better the connection is. Freenet works almost like the brain does, the most popular your data the more connections to it.
Work on freenet to make an alternative to the current world wide web if the ideals dont impress you do it for the technology aspect, make freenet a success and you could end up with millions of users who switch from the regular internet, because the regular internet is becoming more and more censored.
Hey i cant tell you what to do, but if i had the ability ( I dont know java ) I'd help make some kinda front end for freenet

The ads of slashdot are a part of it.
Rarely you get to know about new things by reading them (new computer languages/platforms), but it's interesting to see who sponsors slashdot. The ads aren't the thing that take a lot of download time - but it's the comments that do.
It's not the annoying Java or flash ads that make sounds or explode when you accidently move your mouse over them. They are just innocent ads. I can't see why anyone would filter them.

C is easier than Java only in the sense that Windows is easier than UNIX; there's less of it to learn. Once you've learned either well, however, one can build complex projects much more quickly with Java than C.
C is certainly faster. C is without question better in most cases for low-level code -- whoever thought of writing an OS in Java should be shot.
On the other hand, Java makes it much easier to assemble (fairly) large, complex projects -- which, in case you haven't noticed, Freenet is. Network and stream handling is genuinely easier in Java than in C; the same goes for many other tasks. SQL is another that jumps to mind, though it's not particularly relevant here; proper exception handling is Yet Another Java Advantage (don't you hate checking every function's return value in C? Or worse yet, do you just not do it?), and not having to worry about buffer overflows or accumulating unfree()'d memory over days of operation is damn nice.
Understand -- almost all the code I write is in C, Java or Python, and I respect all three for the things they're good at. Freenet is certainly not a Python project, and (due to the need to structure its design effectively and do correct error handling easily) it strikes me as more of a Java project than a C one.
Yes, more people know C -- but if it takes them twice as long to get to release (tracking and removing all the memory leaks and potential buffer overruns, recreating the network code Java does for them, &c) or just takes newcomers twice as long to understand the program's structure (something OO, when done right, makes easy), that's no killer advantage.
Java is object oriented, the whole point of the object oriented design,is to help with complex BIG projects.
However freenet while its complex, i dont think its a "BIG" project. KDE is a big project and its not nearly as complex as freenet.
Big projects benifit from using objects.
As far as if C is easier than Java, to me C is easier, Java has"MORE" syntax than C, its a totally diffrent way of thinking (Object Oriented)
Theres alot of confusing things about Java.
As for bugs yes Java can handle bugs. I just dont think Freenet benifits from the Object Oriented style, please tell me how.
You are right about memory leaks, you are right about buffer overrun, what you forget is how much C code is already written, people wouldnt have to reinvent the wheel for alot of things like they will have to do in Java.
You are right it will take them longer to release at first the foundation, however once that is complete i think C would be nice. If it were C it would also be much easier for Windows users, and Linux users, even Mac users because it could be intergrated very well into the OS.
As far as understanding structure, I think C code is more unstandable but thats just me, anyhow my point is, If its written in C it would have more developers, the project might have been more on the scale of gnutella instead of what it is now.
It would be easy to write a freenet frontend in visual basic for windows but as for java, how do you write a front end for that.
I dont know, I think java has its advantaged but if they needed object oriented i still think C++ would have been better. But if they dont need object oriented, C would have been my choice.
My choice doesnt mean much though does it.

Superb choice of threads to mention. I highly enjoyed seeing knox exposed as a petty bitch.
Why Freenet? It's such a tremendous effort, for something that so few will use. In fact, does anyone actually use it for getting work done? Heck, does anyone use it for anything? (I honestly want to know!)
Forgetting about all the anonymity/freedom-related arguments in favor of freenet... it provides a means of allowing the users to pay for your content distribution!
This is great for folks running, say, a free webcomic who hitherto have had to pay $750 a month for their bandwidth. With freenet, the cost of distributing the content is paid by the users; the more the users use it, the more it's automatically distributed. That has a great deal of value. If I were running a non-commercial web site with a fair bit of traffic and couldn't find free hosting elsewhere, I'd probably run it on freenet myself (perhaps with a for-pay web version so folks who want to go that route can pay for the bandwidth themselves). If the webcomic authors wanted to take advantage of freenet's anonymity features (which they probably wouldn't -- getting credit for your work is a Good Thing), they could also avoid being sued by corporations angry about such things as, say, Jesus peanut butter cups.
Sure, not many people use it right now. Once critical mass is reached (of either users or content), it's reasonable to expect that to change.
a well written C program can be as portible as Java.
Not if you want to use advanced OS features such as sockets or a GUI and the most common workstation operating system on the most common consumer workstation doesn't support POSIX well, let alone X11. Or are you talking about emulating POSIX on a winbox (that is, the opposite of WINE)?
Java code is not native
Bull. GCJ can compile Java language source code to a native binary using the same code generator G++ uses. Granted, you do lose a bit of performance to the GC thread.
Will I retire or break 10K?
real-world user-applications seldom do number-crunching in tight loops for hours
"Seldom" referring to media players and 3D games, correct? Apparently, you meant that many popular applications (such as Freenet) are I/O bound rather than CPU bound, and the Java platform introduces little penalty there; granted.
Will I retire or break 10K?
the keep-banners version isnt going to work, you left out the declaration/assignment of the img array.
:)
Please find the fix below:
function delAds()
{
var imgs = document.getElementsByTagName('IMG');
var i;
for(i = 0; i < imgs.length; ++i)
if((imgs[i].width > 300 && imgs[i].width < 350
&& imgs[i].height > 250 && imgs[i].height < 300)) {
imgs[i].src = "";
imgs[i].width = 0;
imgs[i].height = 0;
}
}
As you can see, I've eliminated the (now obsolete) iframe code, and reinstated the IMG elements.
Just download the copy to your hard drive and change the script src to file:///path/to/adkiller.js as appropriate :-)

Starship Trooper (User #523907) posted some code that may or may not kill the new ads here in Slashdot [haven't tried 'em, so I can't vouch for their effectiveness].
jamie pointed out that it might not be safe to run javascript hosted on someone else's server.
Astral Traveller (User #540334) then says:
Hmmm. I guess Astral Traveller and Starship Trooper are the same dude. How many other accounts you got? Ever mod yourself up? (ever mod yourself down?)I don't doubt that lots of people have multiple accounts, but if you do you should be careful which ones you use in which thread :-)
If all this should have a reason, we would be the last to know.

Seriously.
Well, this definitely needs to be boosted into the airy ranks of '2' comments. Banned for posting code that blocks slashdot ads! Geez, given the editorial fairness we've seen up to this point who would've thought?
A.S.'s, original comment, moved up the firing line to keep it from languishing in the ranks of '0' comments. Yes, I know, redundant, but this is also a test to see if I can still post later on today:
Unfortunately, "Starship Trooper" has been banned from posting after this incident, so I was forced to used "Astral Traveller" (the similarities should be obvious) in order to reply to jamie (after which A.T. was banned from posting too). So, yes, I was fully aware that I was using multiple accounts while referring to myself. And let this be a lesson -- don't post anything that threatens VA Software's new business model! -S.Trooper/A.Traveller

My god carries a hammer. Your god died nailed to a tree. Any questions?
Because it says, right in the original fucking comment, to COPY IT TO YOUR OWN WEBSPACE before running it! jamie's just spouting crap in a vain attempt to discourage people from using this trick.
Well, you will have at least 6 months between changes. .docs can contain all kinds of personal info, which can be awful if you make the .doc file publically available, as then your private info will leak out into society at large. Similarly, you can inadvertently copy a sensitive file into Freenet, and once that happens you can never remove it again. Hell, you can even accidentally copy a Word file which contains private info into Freenet, and by the time you realize that your private info was in the .doc, it is too late to remove it. I also could have pointed out that if you thought that Outlook was a dangerous medium for spreading all kinds of filthy viruses, then you have much more to look forward to, because when Freenet is in the full swing of things, there will be no mail servers on which to host virus-scanners, and no way to filter out all of the infectious garbage! Of course, I am a very thoughtful person, and being sensitive to your needs I didn't bring any of this stuff up. It's a good thing I know when to keep my mouth shut, huh! 8D
:-(
It was supposed to be a little sarcastic, but really I was sparing you.
I could have brought up how Freenet can just as easily harbor unsavory trojans and wicked macro files, just like Word.
I also could have talked about how the binary Word
Don't you feel better now? I would say "See, I told you so!" if I were one of those kinds of people, but I'm not, and it's a good thing too. See, I can be comforting when I try. Not at all sociopathic-like. 8P

I found this thread after reading this article on K5. Yes, it is yet another variation on the "imminent death of /. predicted, film at 11" rant, but the many pointers to bitchlapped threads piqued my interest.
/. the benifit of the doubt (I had always felt the k5 readership to be pedantic and elitist FAR beyond even the worst /. poster) but this really takes the cake.

And while I honestly had no plans to sneak any malicious code into my script, I can see the risk. I just wish jamie would try to find a more constructive solution than outright banning of all Javascript. I liked joe_jones' solution of filtering out document.cookie, which would put a huge dent in the danger of rogue scripts. From your comment, it would probably be wise to block document.write() as well. However, that may be too difficult to implement. We'll see what jamie's final solution is.
