DIY: Jot Pro Stylus clip

Jot Pro in my thought is by far the best stylus for capacitive screen like iPad. I am using it all the time and even bought the iPad case that can carry this Jot Pro. However, the only draw back is the lack of pen clip. It’s difficult to put in your pocket without worrying about losing it. Here is what I did to make DIY clip for Jot Pro.

1. Buy a pen with a big clip (my pen is 25c)

2. Take the clip out and make a cut on the outer ring

3. Done ^__^

1. Mail the XPS file with Gmail

2. Instead of download the file, choose to view file

3. The file will open with Google Doc and then later you can convert to PDF ^__^

Put Linkedin profile on WordPress 3

I have been using a static resume (About me page) on this blog for quite sometime. I also have my CV in Linkedin, which is my main professional resume. Consequently, it’s inconvenient if I need to update my profile, I have to go editing everywhere. Today I’ve found the best solution: “Link my linked in profile into WordPress page”.

This “Linkedin Resume” wordpress plugin is awesome. Once I installed it, I just go to Setting > Linkedin Resume and input my Linkedin public profile. 

Then I just have to put

“[ linkedinresume ] ” (no space between brackret)

on the page that need my profile to appear [see].

From now on, I need to only maintain my profile in Linkedin ^__^


Switch language on Mac with grave accent ( ` )

For Windows users who familiar with switching between language with grave accent ( ` ), using Mac input source switching with Command + Spacebar might be difficult. After a long time of confusing, I finally see the light. I just need the same setting for all devices.

All you need is this piece of software Keyremap4macbook []. After download and install (in System Preferences), you need to map ( ` ) to Command+Space .

That’s all, now I can use ( ` ) to switch language in both Mac and Windows.

Setting up Thai in XMBC on AppleTV2

After setting up XMBC on ATV2, I felt like I really use full potential of ATV2. The good thing (for me) in this version of XMBC is I can set up Thai Character in Region setting. However I can’t read Thai because XMBC does not include Thai font in its package. Here how to add Thai font:

  • Log on to ATV2
    • I use Cyberduck to access into ATV2
    • It’s already found my ATV2 via Bonjour network
    • username is “root” and password is “alpine”
  • Go to XMBC > Media > font then copy Thai font to this directory

Done, now I can see beautiful Thai font for file list name ^__^

Jailbreak Apple TV 2g with GreenPois0n RC6

I have tried to jailbreak my AppleTV 2g with both GreenPois0n RC6 and PwnageTool 4.2.1 for several times, none of them working well. Fortunately one day I incidentally made it work. Here how I did:

  • I follow the instruction from
  • The problem is I can’t go to DFU mode with the instruction given. It always fails at the end.
  • To FIX this problem, I just enter the DFU mode before running GreenPois0n
  • First I plug in both USB cable and Power cable in to AppleTV then press Menu + Down until the white flash blinking rapidly.
  • Next release both button, the white light will stop blinking.
  • Now immediately hold Menu+Play until the light
  • Once in DFU mode (iTunes will show up), run GreenPoisi0n. It will start jailbreaking suddenly.
  • Wait for 5 minutes, click complete and it’s done.
  • PS. my AppleTV was stuck in recovery mode after the jailbreak process. I have to use RecBoot to kick it out of recovery mode.

3 Multiple displays with 12-Core MacPro 2010

The task is connecting MacPro with 3 monitors, so I ordered Samsung monitors which come with Display, DVI and VGA port on each monitor.

MacPro 2010 comes with two mini-Display ports and one Dual-link DVI. The first trial is to convert mini-Display port to DVI using this mini-Display port to DVI adapter.

However, because of insufficient power, only 2 displays are working (the ones from mini-Display ports)

So I have to order mini-Display port to Display port cable from CircuitAssembly to make these three screens work. Now everything is perfect, I can drive 3 monitors simultaneously.
