dd-wrt has built-in support for a whole list of Dynamic DNS services. Unfortunately, they only support HTTP-based services. I use a standard RFC2136 DNS update. Here’s how to add nsupdate support to dd-wrt.
Although the big builds of dd-wrt contain IPv6 support, it doesn’t support ip6tables. Hence, I choose to use the mini build (which gives me the most free space) and add the missing parts myself. I shamelessly used OpenWRT modules to save me the trouble of figuring out how to compile each library. (Unfortunately, my router isn’t supported by OpenWRT, so I need to stay with dd-wrt for the base system).

Since none of the dd-wrt releases include ip6tables support, I added it myself. The standard kernel does support module loading, so you can simply add additional kernel features without reflashing the device. You do need some writable storage. I use the remaining 4MB of flash using JFFS, but using an external storage (USB, network, …) is also possible.
Since you can’t run a complete build environment on the router itself, you’ll have to set up a cross-compiling environment on your own machine. As I found out, this isn’t always very easy to do…

I bought myself a new WiFi router. When in the shop, I specifically searched for a router that is supported by dd-wrt, and has (at least) 8MB of flash. I settled for the Linksys WRT320N: it has a dual band (switchable between 2.4GHz and 5GHz, not simultaneous) 802.11a/b/g/n radio, a 4 port GbE switch, and a WAN port. It houses a Broadcom BC4717 processor running at 354MHz, 8MB of flash and 32MB of RAM.
The default Linksys firmware is actually not bad, but dd-wrt just offers a ton more features: Multiple SSIDs, IPv6 support (including Sixxs tunneling), WAN volume monitoring, custom firewalling, traffic shaping, … So I decided to void my warranty and put my router on steroids! Mandatory note: this may very well turn your router in to a very expensive brick.
I usually don’t just repost other people’s posts, but this one really deserves some extra attention. It explains a very elegant way to hop using SSH.

I tried to upgrade my silverlight plugin from version 3 (3.0.50106.0) to version 4 (4.0.50917.0). I downloaded the DMG, followed the wizard all the way through, restarted Firefox as requested and saw that I was still at version 3… Strangely, Safari did load and use version 4, so the install was successful. So I searched my entire system fore some remains of Silverlight 3, without success.
The only place I could find the old version mentioned, was in the pluginreg.dat file in my firefox profile. I just erased this file, and it all magically worked!
One very nice feature the iPhone lacks is the ability to request a delivery report on text messages. I usually abuse these by sending a text message to family/friends while they’re on a plane. As soon as they land and switch on their phone, I get a delivery report. Which essentially tells me “for free” that the person has landed. (With Belgian carriers, receiving text messages is always free, even abroad, because you can’t refuse them).
I’m a fan of keyboard shortcuts. Not to memorize them, but to use them. It’s just so much quicker to hit CMD+W to close the current browser tab than it is to carefully navigate your mouse to that 12*12 pixels button. However, this didn’t work flawlessly. Sometimes I get the ubiquitous “do you want to save?” question and I have to use the mouse to click “Don’t save”; Tab doesn’t seem to work.
Until I found out how to change that setting, that is. It’s hidden in the System Preferences under Keyboard – Keyboard Shortcuts. You can change Full Keyboard Access to “All Controls”, which is the behavior I’m used to from Linux and Windows.
The graphs of the ESC logging data I made earlier aren’t as pretty as HTML5 allows… So I retried it using HighCharts and a bit of JavaScript. The result is a standalone LogViewer page which interprets and graphs the log data entirely client-side. The page itself is fairly boring until you feed in a log file.
Clearly I’m not a layout specialist, but the functionality is there.

Got my miniTitan repaired; at around €20 it was fairly cheap. But the governor-config still needed to be done. So I gave the collective a punch while in a hoover and noticed a drop in RPM, as it was last time. I changed the settings to have a governor gain at “Medium (25)” instead of “Low (15)”.
