Routers all maintain a reasonably sized set of source/destination/timer triplets. If a packet comes in from 'source' and is headed to 'destination', drop it. When 'timer' expires, drop that rule.
A special new "Add rule 'source,destination,timer'' packet is added, to be sent to a router. This causes the router to initiate a 3-way handshake with 'destination' to confirm that they requested the new rule, and if so, they add the rule to their table and set the expiration timer.
The idea is simple: If you're being DDoS'd, you don't have much bandwidth, but you always have bandwidth available between you and the first router, so you can always send them special packets telling the first hop router to drop all packets that you suppose are malicious, with a small timer so that you can renew it. After that's done, you should have eased the traffic enough to send more table-update packets to the second hop routers, and then to the third hop routers, and so on, until you've pushed the 'timed reject rule' right back up the traceroute chain until its at the source's doorstep and can go no further. At that point, not only are you free from the DDoS, the routers themselves no longer have to handle the traffic, either, as you've cut it off very near to the source.
The rule expiration timer makes it so that you need to actively maintain the rules or they'll disappear, and furthermore, it makes it so that when the DDoS stops, normal traffic can resume just fine. You can always 'peek' to see if the DDoS is ongoing by letting a few timers expire and watching to see if the malicious traffic is still coming through. If it is, update the rules and block it for some more time.
Slashdot’s new interface could kill what keeps Slashdot relevant
Flashy revamp seeks to draw new faces to the community—at the cost of the old.
by Lee Hutchinson — Feb 12 2014, 6:55pm E
In the modern responsive Web Three Point Oh Internet, Slashdot stands like a thing frozen in time—it's a coelacanth stuck incongruously in an aquarium full of more colorful fish. The technology news aggregator site has been around since 1997, making it positively ancient as websites are reckoned. More importantly, Slashdot's long focus on open source technology news and topics has caused it to accrete a user base that tends to be extremely technical, extremely skilled, and extremely opinionated.
That user base is itself the main reason why Slashdot continues to thrive, even as its throwback interface makes it look to untrained eyes like a dated relic. Though the site is frequently a source of deep and rich commentary on topics, the barrier for new users to engage in the site's discussions is relatively high—certainly higher than, say, reddit (or even Ars). This doesn't cause much concern to the average Slashdot user, but tech job listing site Dice.com (which bought Slashdot in September 2012, along with Sourceforge and a number of other digital properties) appears to have decided it's time to drag Slashdot's interface into the 21st century in order to make things comfortable for everyone—old and new users alike.

If the beta is still around, there's a pretty good chance that I won't be back.
May your coffee be inexplicably stale! May your socks spontaneously change colour and refuse to match! May your sheets repeatedly expose your toes to the chilly air! May your toast be burned, and your pepper be too hot! May your daughter seek to party excessively and bring you endless worry! May your nail clipper be dull, and your pens out of ink! May all of your favorite TV shows be cancelled!
Grrrrrr, I'll put
Hmph. Urgh. I'm so angry right now..
Change happens, and for those of us who work with technology for a living it is the only constant. Change is a process and in and of itself is not a bad thing when it offers improvement. Unfortunately the change that has been offered negatively impacts the look, interface and most importantly the functionality of Slashdot.
Many people have had trouble reverting back to the classic interface. The new interface simply does not offer the functionality of the old. Things like statistics, comments and layout are very difficult to find. You have a community that lives and breathes data and want to know their data. How is my comment ranked, how many people responded – it’s really all about the dialogue. Can I get the information that I want in a readily digestible format?
As you’re well aware the new site does not offer the very thing that people come here for. This in and of itself is not why your community has organized a boycott of Beta. The boycott was originated because the new version will be implemented whether the community wants it or not.
I want to explain why this change has gone down people’s throats about as well as Windows 8’s Metro interface. The reason has absolutely nothing to do with the interface and everything to do with the perception that the editors and management of Slashdot appear to have.
The message that has been consistently handed down is that we are “your audience”. We are not your “your audience” we are your product. People do not come to Slashdot for the news stories, there are untold other sites that provide those as well as professional and original writing about them. People come here for the community of insiders from across the industry.
Please respect the community and stop what you’re doing. You have commented that you don’t want to maintain two code bases. Your community works in the industry and understands this, which leads many to suggest you abandon the new code base entirely so that you are only maintaining once code base. Tell us what your trying to accomplish and I would imagine that a wide range of experts would be more than willing to help you meet your goals.
I come to
/. for the comments, but with the new Beta, I can't even see anything! It just says:
''Shazbot! We ran into some trouble getting the comments. Try again... na-nu, na-nu!
It seems like the "developers" need to take some advice from people who actually know what they are doing. I'm happy to help explain what graceful degradation means if they like...

Boycott the site Feb 10-17th
If the beat is still here on 18th Feb do not return.
Do not fix that which is not broken.
Oh, BTW, FUCK BETA
