Comcast Intercepts and Redirects Port 53 Traffic 527

An anonymous reader writes "An interesting (and profane) writeup of one frustrated user's discovery that Comcast is actually intercepting DNS requests bound for non-Comcast DNS servers and redirecting them to their own servers. I had obviously heard of the DNS hijacking for nonexistent domains, but I had no idea they'd actually prevent people from directly contacting their own DNS servers." If true, this is a pretty serious escalation in the Net Neutrality wars. Someone using Comcast, please replicate the simple experiment spelled out in the article and confirm or deny the truth of it. Also, it would be useful if someone using Comcast ran the ICSI Netalyzr and posted the resulting permalink in the comments.

It's like knowing multiple languages, or multiple cultures, or multiple cuisines. You can see how different things got made in ways different ways. It also encourages to find out interesting things about the operating systems you are already familiar with, and gives new ideas when solving problems. I always try to expand my knowledge and keep an open mind, knowing that there are many interesting things out there.

I say knowing several operating systems is better than knowing just one. In my life I used MS-DOS 3, Windows 3.1 for workgroups, AmigaOS, Windows 98 SE, Windows XP, BeOS, SuSE 9.1, OpenSuSE, and right now I'm using Xubuntu 9.04 (starting from version 6.10). I ran ReactOS from a livecd. I also emulate Haiku, Slackware, Debian and ReactOS. I'm 15 years old, and certainly going to try more operating systems in the future.

Fullscreen window might work on my puny 15" 1024x768 screen, but on all these new high-resolution widescreens most webpages consist of empty space if you do that. In that case it is often better to have two browser windows side by side. I prefer my tabs on the top, and if Mozilla ever changes that without giving me a choice to keep my tabs I will seriously change the browser. With tabs I can just move my laptop's mouse up and click. The distance is smaller than having the tabs on the side, and on my laptop it's easier to move the mouse up and down rather than sideways (it has only a Pointing stick).

Curved Laser Beams Could Help Tame Lightning 184

Urchin writes "Laser beams just gained a new property — they can curve through space. That's what happens when ultrashort laser pulses pass through a phase pattern mask and a lens, which together shift the most intense region of the beam from the center to the right-hand side. The asymmetry in the pulse causes it to drift progressively further to the right along an arc as it travels. The laser beam is so intense that it ionizes the air it passes through to create a curved plasma channel. Those kinds of channels can be up to 100 meters long — direct them at thunderclouds and they could first trigger lightning to spark and then act as a convenient but short-lived lightning rod to guide it safely to the ground, according to some researchers."
