Clock skew detected. Your build may be incomplete.

Happen to me many times, and keep forgeting this:

find . -exec touch {} \;

Bye bye "Clock skew detected. Your build now can be completed." :)

Running Xorg From rc.local as common user

To start Xserver with no desktop manager at boot time and run as common user, simply put this line at /etc/rc.local
setsid sh -c 'su -c startx username <> /dev/tty1 >&0 2>&1' &

Replace the startx with your Xserver application such as startxfce, startlxde etc.

In my system i want to run the xterm on 1024x768 monitor with whole area active, no need mouse moved to active xterm area, says the geometri of xterm to cover whole area would be 170x59 character size, the command became:
setsid sh -c 'su -c "xinit -geometry 170x59" username <> /dev/tty1 >&0 2>&1' &

Frame Buffer Set on Banana Pi

When you plug the HDMI of Banana Pi running Bananian to low resolution TV or Monitor, you won't get proper display.  To correct this use the frame buffer setting,

sudo apt-get install fbset

Replace the /etc/fb.modes, fill it with these lines:
mode "640x480-60"
    # D: 25.200 MHz, H: 31.500 kHz, V: 60.001 Hz
        geometry 640 480 640 960 32
        timings 39682 48 16 33 10 96 2
        rgba 8/16,8/8,8/0,8/24
endmode

mode "768x576-75"
    # D: 49.188 MHz, H: 46.580 kHz, V: 75.008 Hz
    geometry 768 576 768 1152 32
    timings 20330 128 32 32 8 128 5
    accel true
    rgba 8/16,8/8,8/0,8/24
endmode

Linux FIle & Media Server

I had several external usb hardisk. I need to bring them along with my laptop when needed. I though why not create a file server, so that i can still access it anywhere at home. Utilizing one of the cubieboard, i create this file server.

Samba Server
sudo apt-get install samba cifs-utils ntfs-3g dosfstools

add these lines at the end of /etc/samba/smb.conf
[media]
 path = /media
 public = yes
 writable = yes
 comment = smb share
 printable = no
 guest ok = yes
 read only = no
 directory mask = 0777

Homemade 3G Router/APCombo

This article show you how to make your own 3g router using embedded linux, in my case i'm using a raspberry pi 1 Model B. What you need other then the board it self were 3g modem and wifi dongle. The Wifi dongle that were gonna use, should have multiple tx queue features, one from atheros should do the trick.

Ethernet/LAN was bridged with Wifi. In this way client via ethernet can also connected to the network. The bridge hold the system ip address, and no ip assigned to ethernet or wifi.

3G connection were done by umtskeeper which include sakis3g, AP were done by hostapd working along with dnsmasq for dhcp and brigde util to configure the network bridge.

Media Player On Allwinner device.

This is my note to make media player that work on Cubieboard, Bananapi and other allwinner board. Assume you already had a working debian wheezy system running on the board.

Add these repository:
sudo vi /etc/apt/source.list
deb http://dl.bananian.org/packages/ wheezy main
deb http://packages.cubian.org/ wheezy main non-free

Add gpg key:
wget -O - http://packages.cubian.org/cubian.gpg.key | sudo apt-key add -
wget -O - http://dl.bananian.org/packages/bananian-packages.key | sudo apt-key add -
