Yo, nard dogs!

This is the story of one brave man buying a HTPC (Zotac ZBOX HD-ID40), installing XBMC and getting it to work with Ubuntu. I'm writing this in English, because

a) I believe some other non-Finnish speaking fellows out there might get a kick out of these tips
b) I'm interested to see, if writing actually something relevant¹ in English has any effect on the amount of visitors
c) I get to write kick-ass one-liners such as "Bloody monkey balls", and "Tame the beast". Faaan-tastic!

1. The Preface

So this is what happened. I was minding my own business, idling at IRC, when someone pasted a link of a Zotac ZBOX HD-ID40 mini-PC. Bloody monkey balls, I had to get one myself in order to still be valued among the coolest people on Earth.

The Zotac did not include any hard-drive or memory, so I had to get those as well. The complete setup was as follows:

• Zotac ZBOX HD-ID40
• Western Digital Scorpio Black 500GB 2.5" 7200rpm
• 2 x Kingston 2GB DDR2 800MHz SODIMM

2. The Setup

I wanted to build a HTPC setup utilizing WLAN (wasn't² too keen on having a network cable running across the living room for about 20 meters), using a HDTV as an output for audio/video (connected with HDMI) and having XBMC as the media center software.

3. The Problems

Well, whadaya know... everything did not work. Main problems were WLAN which got disconnected time after time, and getting the HDMI audio output to work. I won't get into all the dirty details I had to endure, in order to get it finally working. Instead, here are simply the steps I used, in order to get my setup working.

4. The Solution

Tättädädää!

4.1 Install Ubuntu 10.10

I installed the 32bit Ubuntu 10.10 into the ZBOX using a USB-stick. You know the drill. I chose to automatically update all packages during installation. Not that it should matter.

4.2 Install additional packages

I installed the NVIDIA proprietary drivers from the GNOME UI. Also, I installed the following packages:

These are required for proper video/GPU support.

4.3 Install XBMC

4.4 Configure audio output through HDMI

The ZBOX does have HDMI audio output capabilities out of the box. But here's the catch; with Ubuntu they are disabled by default. Which makes sense, if you're accustomed to trimming your armpits with scissors that are designed for left-handed people EVEN THOUGH you are right-handed! Holy Bat Mobile... Note to self: I'm awesome at metaphors.

Anyway, here's how to enable them:

• Execute command sudo alsamixer. Press F6, amd select "HDA NVidia" -card, which offers the HDMI audio output
• Press letter M to unmute the channels (text changes from "MM" to "OO")
• Next, use command aplay -l to list audio playback devices available
  • For example, I had -- among others -- the following device:

    card 1: NVidia [HDA NVidia], device 7: NVIDIA HDMI [NVIDIA HDMI]

• Finally, in XBMC audio settings, define custom "audio output device" and "passthrough output device" with the syntax of plughw:$CARD_ID,$DEVICE_ID that matches the HDMI audio device gotten from using the aplay -l command. For example, I used value plughw:1,7.

4.5 Compile WLAN drivers

I could not get the WLAN driver to function properly. It periodically got disconnected, which was extremely annoying. Also, even though the chipset supports 802.11n, it connected only at 54Mbps. I googled the problem, and it was caused by the RaLink RT2860 WiFi Network driver. There were many suggestions on how to solve it. Tried many of them, but none of the "simple" tips worked. So finally I was forced to compile the driver by myself. Here are the steps I used to tame the beast:

• Download RT2860PCI/mPCI/CB/PCIe(RT2760/RT2790/RT2860/RT2890) drivers to Linux from http://www.ralinktech.com, and extract it (extraction directory referenced as $SRC_DIR from now on).
• Modify $SRC_DIR/os/linux/config.mk to contain the following parameters (these have value "n" by default):
  
  HAS_WPA_SUPPLICANT=y
  HAS_NATIVE_WPA_SUPPLICANT_SUPPORT=y
• Modify $SRC_DIR/common/cmm_wpa.c by finding the only occurrence of string MIX_CIPHER_NOTUSE and replacing it with string WPA_TKIPAES_WPA2_TKIPAES
• Compile and install by executing:
  
  sudo make
  sudo make install
• Replace the driver
  
  # Put the WLAN interface down (also disable auto-connect from GNOME Network Manager, if applicable):
  sudo ifconfig wlan0 down
  # Remove the original driver from Kernel:
  sudo rmmod rt2860sta
  # Backup (and move) the original driver
  sudo mv /lib/modules/2.6.32-27-generic-pae/kernel/drivers/staging/rt2860/rt2860sta.ko $SOMEWHERE_SAFE
  # Note, the above-mentioned path may differ. You can use find to locate it. For example:
  sudo find /lib/modules/ -name "rt2860sta.ko"
  # Probe and generate all modules:
  sudo depmod -a
  # Install new compiled driver:
  sudo insmod $SRC_DIR/os/linux/rt2860sta.ko
  # If everything works, perform the following to stick with the new driver (again, paths may differ):
  sudo cp $SRC_DIR/os/linux/rt2860sta.ko /lib/modules/2.6.32-27-generic-pae/kernel/drivers/staging/rt2860/.
  sudo vi /etc/modules
  # And add the following new line:
  rt2860sta

5. Enjoy

Lay back, and enjoy the feeling of true accomplishment. You can't do this Windows, because the bloody thing tends to work nowadays. Go figure...

Hep!

Google julkaisi tänään Google Latitude -palvelun, joka mahdollistaa kavereidensa sijainnin kyttäämisen mobiilisti omalla kännykällä -- luonnollisesti myös webbi-käyttöliittymä löytyy.

Ei se Google pettänyt taaskaan! Palvelu on päättömän helppo ottaa käyttöön, jonka jälkeen vapaa-aika sujuukin mutkattomasti luuria tuijottaen ja kavereiden menemisiä vakoillen. Mikäli luurissa on GPS, näyttää Google Maps / Latitude sijainnin lähes muutaman metrin tarkkuudella -- muussa tapauksessa paikannukseen käytetään verkon tukiasemia, jolloin heittoa tyypillisesti on useita satoja metrejä (riippuen sijainnista).

Kun ahdistus rupeaa saamaan sijaa ensi-ihastuksen jälkeen, voi toki oman sijaintinsa piilottaa tai peräti hämätä vihollisagentit asettamalla sijaintinsa manuaalisesti jonnekin kuuseen.

Härre god! Ihmeiden aika ei ole ohi! Pyppe Productions ylpeänä esittää vallankumouksellisen revolutionäärisen käänteentekevän mullistuksen! Leidiis önd tsentlemen, kyseessä on Kuntokanta -- http://kuntokanta.net! Kuntokanta on dynaamisen staattinen world-wide-web-pohjainen treenipäiväkirja, johon käyttäjä voi tallentaa omaa harjoitusdataansa.

Työkalu on ollut omassa käytössä vuoden alusta lähtien. Päätin ryhtyä moista väsäilemään, koska en yksinkertaisesti löytänyt netistä vastaavanlaista, joka olisi täyttänyt tarpeeni. Pikkuhiljaa sivusto kypsyi pisteeseen, että päätinpä ihan julkaista sen muidenkin käyttöön. Joten ei muuta kuin domain pystyyn ja baanalle, beibi!

En halua millään tavalla suitsuttaa tätä legendaarisen lennokasta ja legitiimiä sivustoa, mutta kannattaa ehkä (siis EHDOTTOMASTI) tsekata.
