First-Person Cooking 第一人称烹饪

Yi Wang — Mon, 17 Jan 2011 23:36:00 +0000

webcam and bike helmet work well together, (only USB wire is enough to fix the camera, no tap needed!)
feeling a bit awkward behind a camera facing forward above head
notable perspective difference between eye and camera
several interconnected USB wires, geometry of kitchen, laptop location

found a paper:
"First-person cooking: a dual-perspective interactive kitchen counter"
http://portal.acm.org/citation.cfm?id=1753992
but they seems were using two fixed location cameras, not really First-Person as in FPS

NTFS mobile drive dies ...

Yi Wang — Fri, 25 Jun 2010 22:53:00 +0000

After NTFS error message shown on Ubuntu 9.10 when plugin in the mobile drive, I follow its instruction.

Use
chkdsk /f
under windows

It detects lots of file errors and just die, Windows still can not see the drive.

I wonder this command actually does break my files since the implementation to access NTFS file system under Linux might (must) be different from Windows.

Switching back to Ubuntu, all files on the drive seems corrupted (partial images, I/O error)

Evil!

[Update]
Recovered most files after doing nothing but wait for one day, still some files lost.
Strange thing to me is those partial files come back as full files.

Install git binaries on Godady Linux share host

Yi Wang — Sun, 11 Apr 2010 14:32:00 +0000

Godady Linux has no gcc, so need compatible binary, following tutorial
http://serverfault.com/questions/26836/setting-up-a-git-repo-on-my-godaddy-hosting-plan

Tried Rackspace Redhat 5.3 and CentOS 5.3 which are x64, therefore their binaries are not usable on godaddy's 32 server. Then compiled git from source on another 32 server (also Cent OS 5.3) and copied the binaries to Godady. It works!

Note:

To check Redhat version

http://rnyb2.blogspot.com/2006/02/checking-redhat-version-installed.html

cat /etc/redhat_release

Cent OS 5.3

To check glibc difference

My machine:

ldd (EGLIBC) 2.10.1
