Like this needs to be explained any further.
As has been said elsewhere, the high-priced turnaround team seems to be getting the job done…
…as long as the job was to send Siebel into a shotgun marriage to keep it alive.

David Wenberger posted this. I have often wondered the same thing.
The comments give you the answer…DOH!

Geeks in the audience should get this in a flash! Especially Dave Winer!

I am not sure what the overall American reaction to today’s bombing in London is. I hope it’s not the usual American response: didn’t happen here, so it’s not important.
I hope that I am wrong.
I am extremely upset. I am feel a connection to all of humanity, and to see the wanton destruction of human life for reasons of hate makes me ill.
Do I want to be a part of this species?

Niall Kennedy posted that the performance degradation at Technorati this morning was not due to traffic resulting from the London Attacks, but due to maintenance on their systems. [here]
Just unfortunate timing. It happens.

My favourite vintner, and maker of the famous Two-Buck Chuck, has released a new wine. Our Two-Buck Chuck 2001 Cabernet has aged very nicely, and after 4 years is a pleasant wine to drink.

I have discovered a little secret of Linux today: tc. The Linux Advanced Routing & Traffic Control project (here) allows you to shape traffic in any way that you want. In most cases, it is used in a situation where a multi-homed Linux box is used as firewall/router.
I have activated it on my Web server, limiting uplink/downlink speeds to 256kbps. I am using this in combination with the rate-limiting feature in iptables to control the morons. Limiting bandwidth to 256kbps leaves me with enough overhead to get in and control the machine, even when the morons think that they are flooding me with traffic.
I really suggest that you look into this, especially if you are in a bandwidth-limited environment.

The continuing sad tale of Apple’s attempt to integrate podcasts into iTunes continues — Geek News Central has more.
I think that my desire for a Powerbook is decreasing the more I hear about Apple’s general stupidity regarding Web 2.0. It will take a long time for Apple to get their credibility back.

Ok, after this morning’s DDoS, I started rummaging around for ways to limit the amount of hurt that my server would handle. And I found the limit function in iptables.

/sbin/iptables -A INPUT -p tcp -d 10.125.1.250 \
      --dport 80 -m limit --limit 6/m --limit-burst 10 -i eth0 -j ACCEPT
/sbin/iptables -A OUTPUT -p tcp -s 10.125.1.250 \
      --sport 80 -m limit --limit 6/m --limit-burst 10 -o eth0 -j ACCEPT

This should help get some of the requests under control.
Also, I discovered this interesting application called tc. Going to see how I can integrate this with some iptables rules.

This morning, my server was the victim of a sustained DDoS lasting approximately 45 minutes. The entire flow of traffic came from the usual group of trackback and comment spam morons.
Now, the good news: b2evolution came through the event with flying colours. The antispam feature built into the product prevented ANY attempts by these morons at inserting comments and trackbacks from being successful.
I have added one more layer filtering to handle these morons. Since they use such a limited number of keywords in their REFERER fields, I just wrote a mod_rewrite rule to send them off to my infamous TCP Port 9080.

RewriteCond %{HTTP_REFERER} .*(pharmacy|poker|casino|blackjack|cialis|viagra| \
     porn|nude|girls|drugs|sex|animal|holdem| \
     stud|hydrocodone|vicodin|slut|anal|xanax|video| \
     oxycontin|russia|-online|online-).*
RewriteRule ^.*$ http://www.newestindustry.org:9080/ [R,L,NS]

This should deal with 90% of the morons. If I missed any keywords, drop me a comment.
