Using Xwindow client-server

Before starting, make sure both client and server (remote machine) have port 6000 open for Xserver (on SuSE, file /etc/sysconfig/displaymanager should contain DISPLAYMANAGER_XSERVER_TCP_PORT_6000_OPEN="yes"). Once you have changed it, restart Xwindow (or refresh it by pressing CTL-SHFT-BKSPACE).

1. From local shell, type "xhost +". This will allow this client to connect to all hosts
2. ssh to remote machine as: "ssh -Y -o ForwardX11Trusted=yes ". If after following steps it does not work, try "ssh -X -o ForwardX11=yes " (although this is less secure)
3. Once we're in remote machine, type "xhost +" as well.
4. if we just want to redirect a single X application, we can pass -display directly to the application. For example, to bring remote xterm window to our local screen, just type "xterm -display address:0", e.g.: xterm -display 192.168.1.4:0
5. If we want to redirect all new X applications to our local screen, modify environment variable DISPLAY. For example: export DISPLAY=192.168.1.4:0 and then type any GUI applications.

Mount NTFS disk to Mac OS X

All portable/external had disks currently support legacy FAT (or VFAT as Linux so calls it) from DOS era. The file system is ugly in a sense that it is a 'greedy FS which consumes more space than many other file systems. We can easily use up all the space in our harddisk just by putting many video files into this FAT-formatted harddisk.

Started in NT, a new format was introduced: NTFS (Next-Technology File System). It is quite decent FS, except it seems doesn't fully support journaling (I heard it does, but not sure about that since it is a proprietary format from Microsoft).

Anyway, I don't want to talk too long about the FS, but I just want to talk more about how could the harddisk possibly be mounted to a OS-X based Mac machines? The answer is: use MacFUSE and NTFS-3g!
These opensources were originally targetting the development for Linux, but some folks have ported them to OS-X.

To install, first you need to install MacFUSE (search google to find the location), and after it is successfuly installed, install the OSX version of NTFS-3g. It may require you to reboot. After reboot, try to connect an NTFS-formatted external hard disk to Mac's available USB port. If the system can recognize and mount it, you're done.

I have a 2.5" "WD Passport" 250 GB external hard disk which was I reformatted in NTFS after I bought it. In the beginning, out of curiousity I attached it to my Linux machine running OpenSUSE 10.3. Out of my suprise, It could recognized and mounted it with no issues. I then found out that on my Linux has NTFS-3g in it installed by default. After googling, I found the ported Mac version. Now, all my machines (OSX, Linux, XP) are able to read/write files into this small-but-nice device.

Most influencing Technology

Sometimes, I ask myself about what is the most influencing breakthrough technology in human life? The criteria I ask first that it must be substantial, it must be ubiquotus and found in most every tool, device or anything people use.

My first answer is Transistor. Why? First, it is one of the tremendous invention in 21st century. Secondly, it can be found almost in any household's equipment. Don't believe me? Look at cellphones, TVs, radios, video consoles, computers, cars, airplanes, spacecrafts, security systems, weapons, medical equipments, kitchen appliances, network devices (router, switches, PSTN), satellites, even in our body (pacemaker), ..., and the list would go on and on. Currently, there is almost nobody can live without it.

The second place is taken by LASER. The invention is so great that it has advanced many other sciences and technologies and used in many applications. It is used in medical equipments (e.g, laser surgeries), in telecommunications, industries, military, mining and oil industries or energy in general, basic science research (Cyclotron, etc.), instruments, biotech industries, entertainment (in discotiques, in all cd/dvd players) and even toys!

The inventors should've got double nobel laurates (yes, I know, they all got nobel laurates in the past, but seems it is not enough considering how much their invention has changed our life forever).

The third one is for the invention of computer or the Internet.

Make Blackjack II as Bluetooth modem on AT&T network

In case you're struggling to make the nice Samsung Blackjack II smartphone as a bluetooth modem, I've found what I need here, or in case the site is down, here I copy-paste the steps:

MAKE SURE TO RE-DOWNLOAD THE CAB AS IT IS CHANGED!!

ok so here's the NEW procedure:

Step0.0: Make sure your device is app unlocked!!**(see below note!); run secpolicies.cab first if unsure or the certs won't take!!
Step0.1 RESET THE DEVICE!
Step1: Install the BJ.WM6.ICS.Enable cab file (it might ask you to reboot)
Step2: navigate to \My Documents and click on the certs.cab file
Step3: RESET THE DEVICE!
Step4: go to start and run internet sharing
Step5: report back and lemme know if i fux0red anything ELSE up :P

this should work on both BJ1/WM6 and BJ2/WM6

file is temporarily hosted at:
http://www.mdots.net/misc/BJ.WM6.ICS.Enable.cab

**run this cab and reboot; http://sems.org/content/download/secpolicies.cab

After reset, I could see "Internet Sharing" under "Application (Start -> Applications -> Internet Sharing).  When I ran it, it showed two choices for PC connection (USB and Bluetooth PAN).

On PC (or MAC, with small diffs):

1. Double click on the desktop icon identifying the connection. If not desktop icon was added go toStart, Settings, Network and Dial-up Connections, GPRS.
2. Enter Username:
3. Enter Password:
4. Enter Password again in the Confirm box: 
5. Verify that the number to dial is *99# and click dial.
   NOTE: If receiving error 678 or 619 the Phone number can also be entered as *99***1#, or *99***(CID Number)#
   NOTE: By default 1 is the CID, but can change.

I've not tested it yet, but seems to work OK.
