Slashdot Mirror

That was a fast slashdotting. Running on DSL? Isn't there a way for Slashdot to test these sites first?

Or, maybe Slashdot can post the CoralCDN link for the article instead of (or alongside) the regular link?

I know, there are plug-ins, GreaseMonkey and other ways of doing it, but on the user side.

Oh, yes... pennies for that simple stuff that any nerd can set up in minutes or less. Now get a cultural expert to determine whether the villain's taunt is close enough to cause outcry among war-torn villagers in rural Africa, and someone to check all countries to see if Initech is a real company that might sue for defamation, and get a linguistics expert to check every character's name for any unfortunate coincidences, and a small army of lawyers to make sure that joke about Chinese-made products will still be well-received in China... and see how many more truckloads of pennies that costs. Also don't forget the accountants to count those penny-carrying trucks.

Modern "distribution" means more than just putting a product in a customer's hands. It means putting a product in customers' hands knowing that it will be as likely to be suitable for that customer as much as it would for any other. Distributing to a global market means the product must be suitable for entire world, with all its quirks and cultures, not just the United States' free-expression orgy. Bandwidth isn't the problem.

You would think that if you were linking to your own site that you'd use a Coral Cache (or similar) link and not use HTTPS unless truly necessary as a self-preservation measure?

*sigh* slashdot

And we had tried to use Coral to minimize the load. Silly Slashdotters who actually follow links :-)

And what the hell kinda URL *is* net.princeton.edu.nyud.net anyway?

http://www.coralcdn.org/

It's been around since, what, 2005 or so? Where have you been?

It's a free cdn http://www.coralcdn.org/

The link is Coral Cached, presumably in an attempt to prevent a slashdotting.

http://www.coralcdn.org/

Coral Cache is what you're looking for, no custom work needed.

We need a new instant mirror site for slashdot. Any suggestions?

Coral Cache fits the bill quite well, I have no idea why the editors don't use it. It'll create a mirror of any url you link to and navigate through, and they can take a slashdotting :)
Follow this link to check out the CCed version of the article.
If you're on Firefox the TADSEE extension provides a handy shortcut to a Coral Cache mirror when you right click a link.

This is why links doomed for a Slashdot article should go through CoralCDN, first.

If you can't see the photos you probably crashed the guy's server, I think it is hosted on his home computer...

Solution: Coral cached link of photos and aerial photo.

Or you can use the Coral Content Network:

As an aside, if I had wanted to submit my page to Slashdot is there a way I could of done it that (assuming it got published) wouldn't result in my host wishing a painful death upon me?

C'mon, I'm sure that your host would love to be slashdotted! Seriously though, try the Coral CDN to take some of the load off. For me, it doesn't seem to be working right now (DNS error), but that could just be the DNS server at my work.

You have no idea what is of use to other people.

Definitely. I think he could take advantage of coral cache to still provide this useful access without paying for it.

He already has a log in system set up. Let anyone create an account, with proper anti-bot measures. If you are logged in, you get normal access to the page. If you are not logged in, you transparently get sent through the Coral Content Distribution Network (via nyud.net), being careful to not redirect CCDN itself. That way they use none of the site's resources but still have full read access.

I've found that it is usually possible to read http://nytimes.com/ articles without the need for login via CoralCDN -- in the case of this article, the link would be http://www.nytimes.com.nyud.net/2008/09/05/science/05brain.html?_r=2&partner=rssnyt&emc=rss&oref=slogin&oref=slogin

Why don't you just give a CoralCDN link to your video's URL?

Well, at least the cached copy is kinda up to date :P

Coral Cache has never worked for me. I really don't know what all the fuss is about.

The problem is that there's not much to compute at Wikipedia. The limiting factor is bandwidth. A distributed web cache like Coral Cache might work, but this generally isn't called distributed computing, just like P2P networks aren't. The main problem would be that web caches have high update latency, but probably it wouldn't matter too much on Wikipedia.

I must admit to never having really used Dijjer, but what you're describing ain't peer-to-peer. Prepending http://dijjer.net/ to any url will make your browser send an HTTP request to the server at dijjer.net (client-server, here we go) causing it to retrieve the file (by whatever means, peer-to-peer or direct download) and transmit it over to you.
As oppossed to directly downloading, this will cause at least twice, probably more traffic. The dijjer server needs to retrieve it, file's transmitted once; you need to receive it - file's transmitted twice. Even if it's free now, it won't be when Dijjer's VC runs out. They need to monetize double the traffic by showing you double the ads the original provider would have (and still will; he'll probably be chosing his site for ad delivery, Dijjer will have to come up with a way to get you to see even more ads).
The coral cache does something similar, but seems more like a research project (non-profit, easier to get funds, easier to get inexpensive (universities) participation and bandwidth).

Have you never heard of Coral Cache?

Free ones - both only require that you change your URL slightly and the both work

I'm a Ubuntu GNU/Linux user and love it. Freedom is my main argument.

Wordpress is notorious for killing servers with heavy loads when there are many incoming connections. You could try making a temporary static page and disable Wordpress for a day or two; then in the comments section make a notice along the lines of "Sorry, due to server issues, commenting has been disabled until 2007-12-06".
You could also see if CoralCache can help you out a smidgeon. Check this page for further details.

Also, a piece of advice: don't sink money into an upgrade because you've been on /. frontpage once. If the load continues to be high, then yeah, go for it, but slashdotters have a short attention span. See a tale about slashdottings here

SmallNonprofitOrganization discovers bandwidth costs have soared due to extra bandwidth required to support downloading of modified code.

Then SmallNonprofitOrganization uses any of the hundreds of services out there to help them, like:

1. Coral Content Distribution Network
2. SourceForge.net
3. SourceFubar

...and so on. Barring that, they just ask a member of the FLOSS community to host it for them, gratis, in exchange for some mention on their website or other non-financial gratification.

If your school is as clever as my old employer, just use Coral Cache. Wonderful stuff.

There are a decent number of companies (and non-profit orgs) that do exactly this sort of thing. Most of the big content distributors (iTunes, MySpace, CNN, etc) use at least one of them. The problem is that these companies work for the content distributor, not the ISP - the CDN "takes the bullet" for the content provider's main servers to offload demand, not offload capacity to the ISP. Unless the ISP sites one or more of the CDN's proxies at the customer edge of their network (which is not uncommon, but hardly ubiquitous), the ISP still has to pay to move the traffic to their customers from the proxy, and if they did have one it would be in their POP, not next to every DSLAM and cable head-end, which mean the path between the CDN proxy and the customer still has the same bandwidth requirements.

I know the parent is a troll, but this gets better:


Error: 403 Forbidden

Blacklisted??? How the heck do you get blacklisted from Coral Cache?

Try the Coral: http://www.attrition.org.nyud.net:8090/postal/z/03 3/0871.html

For those interested in making your own Corals sometime when an article has already been slashdotted, head over to http://www.coralcdn.org/ and follow the instructions or just put the URL in the textbox. :)

You could've used CoralCDN if you wanted to make sure your quota didn't get hit. I've tried priming it for the image, but I've had no luck.

I wonder if there's some kind of law/rule against campaign websites using a free mirroring service like Coral CDN

I only ask because:
A. It would solve some of their bandwidth problems
B. There are lots of rules against valuable freebies when it comes to politiking

I wrote a quickie article in an attempt to simplify network neutrality for the lay person.
(I linked to the Google cache 'cuz my server won't take the load and Coral Cache seems to be down)

Mirrordot should die if they don't get serious about caching articles. They don't cache images, and only cache the first page of an article, which is useless on the case of this article, and many others.

You would do better to recommend Coral Cache

Coral cache (http://coralcdn.org/) with mod_expires to tweak the cache time and adjust length for high traffic times and mod_rewrite to drive everyone but Coral servers to the Coral cache. Not perfect but it could keep an otherwise dead site to appear alive for an extra day or so. Add in it's completely free, doesn't alter your pages and the only limits are a max single file size is ~35M and a daily bandwidth cap at 250G it's not a bad way to go.

The question is would this take enough heat off of Blue Security to keep going?

Now when will Slashdot use MirrorDot or Coral Cache for links from articles, instead of bringing down small sites?

eg. http://slashdot.org.nyud.net:8080/article.pl?sid=0 6/05/11/1329254

Alas, downloading the AVI from CoralCache doesn't really help you. When you grab the AVI via the cache, it sends you to the original site

Because of bandwidth overuse, we temporarily capped off Coral to disallow transfers of files greater than 50 MB. [...] instead of just returned some type of error message (like 403: Forbidden), we are transparently redirecting clients back to the origin site, where they at least have a possibility of downloading the file, and the server is not in worse shape than pre-Coral.

I'm in Germany and I use Coral Cache to bypass these restrictions. It's not perfect, but a workaround.

YouTube just works.

That should be http://willlangford.com.nyud.net:8080/geekpages/fi refox/. Port 8080 works better behind firewalls and is now also the offical port on http://coralcdn.org/.

With that, use Coral extension! It works well in my Mozilla v1.7.12 installations in Windows XP, Mac OS X 10.2.8, and Linux (Debian).

I still prefer stand alone Coral Cache extension for all Web sites links, not just /. Very useful on Digg too.

Any random donations from slashdotters will be FAR outweighed by his bandwidth bill this month. For Chrissakes, he posted *movies!*

Our apologies The IBM developerWorks Web site is currently under maintenance. Please try again later. Thank you.

Personally I think that links in slashdot articles should be automatically coralized (or something similar to that, maybe using a different system) in order to avoid taking down all these sites.

Here's an idea for the Coral team: what about converting to Coral all links in a coralized web page?

They have a FAQ entry about that. Basically, in order to eventually move to a 'anyone can run a Coral Cache server' model, they need a digest method to ensure a malicious Coral server doesn't insert adverts (or anything else). This means they can't edit the page at all.

For now, I guess we can all use Greasemonkey. I suspect there's a script to do it already available, but even if not, it wouldn't be hard to create one.

Speaking of the /. effect, I can't get to the Allpeers link in the story but the Coral link is definitely working! The Coral FireFox extension rocks!
