ppsspp - Best linux psp emulator

Just have a test on ppsspp. By setting the frame skip and the controller, I can play psp games on my old Thinkpad X61. Nearly no other configuration is needed. I can play with the rom smoothly on my linux computer.

Spec:
T8300 with X3100 onboard

There is less games on linux machines but I am sure ppsspp can give some fun to those who work alot on linux.

[How to] Setup Chinese Input Method on Linux - SCIM

SCIM is a very good Chinese input program for Linux, exspecially for 速成 (Chinese Quick) Method. Setup is very simple in arch linux

1. Install Package
# pacman -S scim scim-table

2. To enable it in startup
$ vim ~/.xinitrc
export XMODIFIERS=@im=SCIM
export GTK_IM_MODULE="scim"
export QT_IM_MODULE="scim"
scim -d

exec startlxde

Sometimes it is not work for reload setting on the tray icon. But reboot computer can help.

New Computer - migrate arch linux from AMD to intel

For years my computer is used, it was found dead after 7 years of working of my AMD Computer. After recover from sadness, I bought new parts to fix it. As the original one was using DDR2 which is quite outdated, I bought a new (not means fast) CPU and mainboard.

Let see the migration spec:
Original Config:
AMD Athlon II X2 240e
J&W Nvidia Geforce 8200 Mainboard
2GB x4 DDR2 RAM
GPU: nvidia onboard

New Config:
Intel Pentium G3258
Asrock B85 Mainboard
8GB x1 DDR3 RAM
GPU: intel onboard

Software:
Arch Linux 3.18.6-ARCH 64bit

After connect everything, computer bootup as usual. It boot up successfully to console user login.

The following is not work:
1. X
2. network

For the network part as the interface index was changed, just amend the configuration on netctl, the dnsmasq (dhcp server and dns provider) and dhcp client and everything works great. Just a reminder that the service of original setting was still running, and these services should be stopped.

For X windows, as I original was using the open-source driver xf86, what I need to do is uninstall nouveau, remove all the configurations and install package "xf86-video-intel" from pacman and it works!!

[How To] Bridge network interfaces using netctl

There are some ways to bridge network interfaces. The most popular one is "brctl". Other than brctl and we can use netctl to preform this task. relativly easy with easier settings.

1. Create a configuration file
# cat /etc/netctl/bridge
Description="Example Bridge connection" 
Interface=br0 
Connection=bridge 
BindsToInterfaces=(enp3s0 snp3s1) 
IP=static 
Address='192.168.1.1/24' 
#Gateway='192.168.10.200' 
## Ignore (R)STP and immediately activate the bridge SkipForwardingDelay=yes 

2. Just start it
# netctl start bridge

3. If it works fine, just enable it during boot
# netctl enable bridge

Nice and done.

a good reminder that the interfaces in the bridge should be disable the DHCP settings.

This is a awesome site that can generate an iOS application from pictures on Dropbox. It's good for generating prototype of mobile application.

nbench - a simple computer benchmark tools for linux

nbench is a very small program that can benchmark a device base on the computation power of AMD K6-2 233 MHz (ha~ very slow CPU). It can also be use to compare the performance on ARM base devices.

The results of my computer. Not that fast
