2012-05-30T05:53:00.004-07:00

Today, I upgrade my fedora 16 to 17 on my laptop Fujitsu SH561.
There is some note about updating process.

1. Dump or back up your data first to ensure you can recover when issue occurred.

2. Get root permission

# yum update
# yum clean all
# yum install preupgrade
# preupgrade

After you make command "preupgrade", GUI upgrade GUI program will lead you finish upgrade process.
Or your can do this command by CLI.

# preupgrade-cli "Fedora 17 (Beefy Miracle)"

(It will take a period of long time and reboot your OS, be patient)

Mac OSX Python IDLE installation easy way

2012-01-02T20:38:00.000-08:00

When we use Python on Mac OSX, we are confusing on Python environment with different version.
How can we develop each version Python on Mac without complex environment set up?
Using IDLE is a simple way and graphic user interface IDE.
First, we need to install tcl/tk GUI tookit to combine back-end python to front-end IDLE.
We can download ActiveTcl 8.5.11 (10.5+ x86_64/x86) and install via DMG file.
http://www.activestate.com/activetcl/downloads

Second, after we installed AvtiveTcl 8.5.11, we can choose Python version DMG file to install.
Python 2.7.2 (10.6 10.7 x86_64/x86)
Python 3.2.2 (10.6 10.7 x86_64/x86)

Then we can see Python X.X directory in our Applications directory.

Open the Python X.X directory and click IDLE, we can open a IDLE window with Python version.

Now we can write code on IDLE with different Python version by easy way.

#gcc -O foo.c -o bar.out
#./bar.out

Compile a C program file to a execution file.

-O -> Optimization parameter

-O3 -O2 -O1 -O0 -> 0 do not optimize, 3 is best optimization.

#gcc -Wall -g foo.c -o bar.out

-Wall -> displayed the warning message
-g -> Using gdb debugging and show error message

#gcc -I/usr/include -L/usr/lib -lm test.c -o test

-Idir_name -> find the header file in directory

-Ldir_name -> find the linrary file in directory

-llibfile_name -> join a library file "libm.so" overpass lib & .so

Synergy KVM software control on MAC OSX & UNIX by MacBook Air to Mac Mini Server

2011-03-28T01:17:00.000-07:00

download & convert file => Synergy Download

you will find synergy-x.x.x-MacOSX-Universal folder

Server (MacBook Air keyboard & touchpad)

open and cp doc/synergy.conf.sample synergy.conf

vi the conf file like this

section: screens
   foo.local:
   bar.local:
end

section: links
   foo.local:
   right = bar.local

   bar.local:
   left = foo.local
end

execute the synergy server by configure and listen client connection

#sudo ./synergys -f --config synergy.conf

Client (Mac Mini Server + screen)

#./synergyc -f "HostName or IP"

The result is that can use Air's keyboard and touchpad to remote control the

Mini Server screen and key-in.

And I have more efficiencies to do my job by the one keyboard and touchpad with two Macs.
