Redirection Proposal

Ideas, RSS, Tech

As many people have heard now, blogs that were previously hosted at weblogs.com are now needing to find new homes. Dave is going to be sending people their backup files but it looks like a lot of links may be broken, and some people proposed keeping a list of the old and new URIs.

Why not go one step better? I apologize if this is not technically feasible for whatever reason, but here’s my idea. DNS is very flexible, Dave can have specific A records for subdomains of sites that are going to stay under weblogs.com, and then set up a wildcard * A record to point to a different IP. This IP could be anyone running a service that would allow people to redirect their old domains to their new ones. Technically this would be pretty simple, no more than a few hours of hacking. The machine serving the redirects could have a wildcard virtualhost entry in Apache and a simple PHP script (or Python script, or RewriteMap) to serve 301 Moved Permanently headers depending on the hostname.

It could redirect to whatever the site owner wanted. The hosting overhead would be minimal. I’m willing to personally commit to writing the code and hosting it for at least 2 years.

Overping

Tech

I’m moving Leonard off my updated list because he seems to be pinging constantly, even when there are no updates or changes. With my old-school aggregator style it makes it very annoying to visit his site. Moral of the story: don’t cry wolf with your pings.

Mmm Apache

Tech

I just got Apache 2 configured locally to serve all the different web apps I run locally (phpWiki, Tasks, WordPress, phpCoder, and some propietary stuff) as different virtual hosts with unique fake hostnames. I don’t know why this is a big deal to me, but it’s much cleaner. My local wiki has grown quite a bit, with hundreds of pages in it now. I’m not sure how I functioned before

Linux for the Masses

Open Source, Tech

It’s not there yet. I’m being totally unfair, because comparing Windows or OS X to the Linux distribution I’m using (Gentoo) is like apples and oranges. Gentoo is meant for people who are comfortable with the command-line and want to experiment. (It’d be fairer to compare Windows to Suse.) But I just want to bridge a connection between an ethernet card and a wireless USB device. Is that too much to ask? When I did this in Windows I just highlighted the two connections, right-clicked, and chose “Bridge Connections.” It spun for a little bit and then it was done. End of story.

The work started yesterday, when I figured out that the reason nothing would emerge is that there were bad GCC flags in my make.conf file. How they got there, I’ll never know. Bad ebuild I guess. So I got that fixed, synced, and updated world. 85 packages! The next day I compiled a new kernel (2.6.7-rc2) but forgot to load the Tulip module required for my ethernet card. Recompile, reboot. Runs great, and I tell myself everything is running faster. Right now I’m bridging my desk LAN to the main router through the Windows desktop, and since I just moved the linux box on a new UPS I’d like to move the wireless connection there too. I was feeling lucky, so I tried just plugging it in to see what happened. dmesg, device not recognized. Search search search the excellent Gentoo forums, find out that to get my MA101 working I shouldn’t use the drivers from Sourceforge, but rather the at76c503a Atmel drivers for wireless USB devices. Download, compile against current kernel sources, install. Reboot. Don’t have any wireless tools. emerge wireless-utilities. Twiddle for 45 minutes to see why it won’t see any networks. Forgot to enable “Wireless radio (non-HAM)” support in the kernel. Recompile. Reboot. iwscan shows my network, iwconfig wlan0 works as expected. The instructions that tell me to put in ad-hoc mode are wrong. (Hour later.) Put it in Managed mode. Cycle the device and run dhcpd wlan0. Ping Yahoo. Online! Track down documentation on bridging. Emerge bridging program. Appears to run fine, but gives a funky error and doesn’t seem to do anything. Add “802.11d bridging” support to kernel. Recompile. Remount /boot. Copy kernel. Reboot… Computer loads everything through Gnome, then mouse and keyboard freezes. Switch back to laptop, write blog entry to let off steam. Reboot again, just to see if it’ll work. Loads, run brctl.So far so good. brctl addbr mattlan returns br_add_bridge: Package not installed, which seems to indicate that the proper kernel module isn’t installed. Would check the .config, but the computer just froze again.

I need some rest.

More Pingomatic

Tech

66,639 pings on Ping-O-Matic yesterday, let’s see if we can beat that today. 🙂 I rewrote the pinger deamon in Python, because the old PHP one was crashing the system on a regular basis. The new one is amazingly light, and was ridiculously easy to write. So now Ping-O-Matic is powered by PHP, Python, Perl, and caffeine. Right tool for the right job.
