HOWTO Let lighttpd listen to both IPv4 and IPv6 on *BSD.

Okay, I've managed to let lighttpd listen to both IPv4 and IPv6 requests without using IPv4-mapped addresses. According to an Internet draft, IPv4 mapped addresses are considered harmful (R.I.P., itojun :). This has already been turned off in *BSDs by default but not in Linux.

Anyway, I've found out that if sysctl net.inet6.ip6.v6only is set to 1, enabling IPv6 in lighttpd would cause it to listen to IPv6 only. To solve this, you need to use these settings:
server.use-ipv6 = "enable"
$SERVER["socket"] == "" {
If you need to use SSL, simply use:
server.use-ipv6 = "enable"
ssl.engine = "enable"
ssl.pemfile = "/var/etc/cert.pem"

$SERVER["socket"] == "" {
ssl.engine = "enable"
ssl.pemfile = "/var/etc/cert.pem"
Tada! It works:
root@soulfury:/# sockstat | grep lighttpd
root lighttpd 23974 4 tcp6 *:443 *:*
root lighttpd 23974 5 tcp4 *:443 *:*
root@soulfury:/# sysctl -a | grep v6only
net.inet6.ip6.v6only: 1


I'm attempting to compile Moblin OS so that I can try it on my Eee. Moblin supposedly incorporates techniques for making Linux boot in 5 seconds, techniques which were presented on a Linux conference some time ago. According to its official site, Moblin doesn't support non-SSE3 CPUs. My Eee uses a Celeron M ULV 353 CPU, so yeah it's a non-SSE3 CPU. But what the heck, I'll go ahead and try it anyway. It's not like it's going to explode anyway. There must be some patches out there that would it enable it to work.

If it works, I'll try to use Boot Booster so that I can further shorten the time it takes to turn my PC on and load GRUB.

BTW, I'm also interested to know if coreboot works with Eee. Since I would need to mess with its ROM, there would be a real danger of bricking it, and turning it into a very expensive paper weight. Blah...

vimperator for Chrome

I need to have total keyboard for Chrome. I'll experiment with vimperator-like clones for Chrome...


Behold, for Eee customization is such a dangerous territory. It has activated my latent OC tendencies, and now I can't sleep. Hurrrr...


I'm not sure if I should overclock my Eee by default. So far, the performance is good (that is, when I switched to Chrome). I think I'll just let it be, unless I really need it since I run the risk of frying my CPU. I've already fried a CPU once... Anyway, I've found a Quicksilver clone for Linux-- it's called gnome-do. Very cool...


I've always wanted to customize my Eee PC, but I'm too lazy to do it. Anyway, I've come up with a list of usability problems that I need to fix so that I can use my Eee more effectively.
  • Unresponsive browser. At first, I tried using Opera, but I realized that its UI is very ugly, and its speed wasn't as fast as I hoped to be. I was able to solve this by replacing Firefox with Chrome. Chrome's speed can really be felt on an Eee.
  • Small screen. I've solved this by using fluxbox instead of Eeebuntu's default desktop environment, which is GNOME. I've eliminated most elements that waste screen estate, such as the window decoration, taskbar, and other stuff. I wanted to add a cool dock-like app, but I realized that it would waste screen estate and would require a mouse anyway.
  • Crappy touchpad. The solution to this problem is dependent on other solutions (i.e., using a keyboard friendly WM and app launcher). I wanted to do a touchscreen hack, but I can't find the necessary parts here in Cebu. Of course, I can always use a mouse, but it defeats the purpose of using a portable netbook. I don't want to bring a mouse wherever I go.
  • Non-straightforward way of launching apps. I'm not really a fan of Netbook Remix's UME launcher, but I realized that I need something similar to it. Perhaps I need to use something like Quicksilver (a very useful Mac OS X app that lets you run apps anywhere by simply typing its name).

Sending SMS using minicom/hyper terminal and ZTE MF626 modem

Sending SMS messages using raw modem commands is amusing. I learned how to do it because I left my cellphone charger at my GF's house. Without a charger, I'm left with an empty batt. Here's how to send a "Hello world!" to +639191234567:

> Hello world!
+CMGW: 1

+CMSS: 20


I'm putting all my notes here.
