...

1. Seems blanks in file names are automatically removed after synced online.
2. unsyncable files appear after move out and move in a same folder (unknown error for folder?)
3. Upload Error - file point to invalid online Google Doc (older version of docs not supported?)
4. files appear in Mac's trash
5. files appear in root directory of Google Drive

Seems not a very stable backup storage solution yet

An Idea of Management study by using Email Interactions

Email has To and CC fields.

CC is usually to managers involved.

Could study the Interaction of groups, manager and worker, task time span.

Note

Hash thread safe
open addressing

parallel callback
fibonacci

process.nextTick()
spawn Child, sorting

分离，模块化更像是认识方法

First-Person Cooking 第一人称烹饪

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

inspired by

Scaling foursquare with MongoDB meetup

http://www.meetup.com/New-York-MongoDB-User-Group/calendar/13817235/

4sq Outrage caused by RAM (64G on EC2) max out (not CPU bounded)
badge calculation based on entire check-in history
Solid state hard drive, significant improvement on matching with RAM
Hadoop for analytics, separate data collection branch on logs
customized MongoDB build with C++ code for location search given prefix
sharding from day 1 with MongoDB, (not using replica set yet)
validating objects in app, correcting if possible
no map reduce on MongoDB yet
original 4sq code is PHP with ... SQL
