If you get the error message "Please ensure that adb is correctly located at 'XXX\platform-tools\adb.exe' and can be executed.", just check the path setting in your computer environment for Microsoft Windows Operation System.
The adb in tools/ is moved to platform-tools/ for new SDK version.
Add the real path to your path environment.

[Android] Auto detect target device phone
If you do not find your phone in ADB (Android Device Bridge), you may have some issues needed to check.
1. On the device, go to Settings > Applications > Development and enable USB debugging (on an Android 4.0 device, the setting is located in Settings > Developer options).
2. Check USB driver is installed.
3. Go to the folder where ADB.exe in, e.g, C:\Android\android-sdk\platform-tools.
Type command <adb devices> then it should have your device names list. If not, check USB driver first.
or Try adb commands to restart adb server.
adb kill-server
adb start-server
4. Check Android version of your project. Right click your project->Properties->Android->ProjectBuildTarget. Make sure that it's not newer than your device's version.

[Android] Simple way to set up development environment
It is recommended to use Eclipse.
First take time to read Android Official training materials here. http://developer.android.com/training/basics/firstapp/index.html
1. Because Android is Java based, Java SDK is needed to install.
Better to choice the second latest version if possible. The newest version may have some bugs issue.
2. Download and install Eclipse. (The version is better newer because old version that Android SDK may not support)
3. Run Eclipse and install ADT (Android Development Tool)
Help --> Install new software -->
Paste the address http://dl-ssl.google.com/android/eclipse/site.xml then you can install the ADT.
4. Check Android version of your Android phone then update SDK if necessary by Android SDK Manager.
5. Set up Android Path. Eclipse --> Windows --> Preference --> Android
For my case, I install SDK here. C:\Android\android-sdk
6. Follow the tutorial to build your first App "Hello world".

[Xcode] Provisioning profile cannot be found
Use new iOS developer and add to portal as development device.
After building App, the error message shows "Provision profile XXX cannot be found".
Your xcode project file gets messed up your setting.
Just click your xcodeproj and click "Show Package Contents".
Use textedit to open project.pbxproj and remove XXX string.
Then re-open Xcode and build then it should work again.

[USB] Study about HID to serial
The bandwidth on basic HID is limited to 64 KB/sec.
Windows API abstract the software developer from HID reports, allowing the developer to think of the data interface as an unformatted stream of data, similar to a COM port.
Benefits of developing with HID include:
Compatibility with all commonly-used operating systems (Windows 7/Vista/XP, Mac OS X, Linux)
No need for driver development or distribution
Streamlined device/host interface due to standardized (but flexible) HID specifications
Once a device has successfully enumerated, the host can begin sending and receiving data in the form of reports.All data passed between an HID device and a host must be structured according to specifications found in the report descriptor. These reports can be transmitted across either the “Control” pipe (endpoint 0) or the “Interrupt” pipe (endpoints configured to be IN or OUT).
from AN249.pdf (Silicon Labs)
And UART baud rate is controlled by switch HID-to-Serial Chip.
How to differ each HID devices.
Get the number of physical USB devices on the system associated with this combination of vid and pid.
How to implement Software Application:
At the beginning of the application, the application should register device change notifications by using HID_RegisterForDeviceNotification().
2. Write ON_WM_DEVICECHANGE
3. Write a function OnDeviceChange() as a public function for the window.

[iOS6] Passbook status
Below link show the user test passbook function on Phone for airport but unlucky it doesn't work.
I think new technique should get real users and service providers support then it works.

In early of September, 2012, Virgin Australia, Amerian Airlines, United and Delta are first off the mark to confirm their mobile boarding passes will work with Apple's Passbook app being built into iOS 6, so we have chance to see it happen in the future.

買42吋電視
開始爬文， 找尋42吋電視標地
1. 距離
42吋~1920*1080 最佳觀賞距離 = 64.6/ 1080 * 3400 ≒ 203公分=2.0米
這個公式不知怎麼算來的，是用它的高來計算
2. Resolution
光看第四台，解析度會比傳統 CRT 差；除電漿電視或是 Full HD Channel
3. 電視會越來越大， 所以要儘量買大尺寸
4. Smart TV
若有閒錢或是有網路才買
5. 視訊盒內建
現在為數位時代，有的話就不用外接
6. HDMI
現在 Portable device 幾乎都有，所以一定要
1.3的更棒
7. 3D
現在內容還不夠多，先不用買
8. 兩萬有找

[NFC] Technique
Nexus
7,
Nexus
S, Galaxy Nexus, Nexus Q, Samsung Galaxy S3, HTC One X contains the same NFC
chip (PN544 by NXP Semiconductors).
MIFARE Classic is a technology by NXP, so it is supported by NXP's NFC chips
Blackberry contains an NFC chip by a different
manufacturer so can't read NXP MIFARE Tag.
Based on NFC Forum, list tag types:
- Tag 1 Type: e.g. Broadcom's Topaz/Jewel
- Tag 2 Type: e.g. NXP's MIFARE Ultralight (incl. Ultralight C) or NTAG203
- Tag 3 Type: e.g. Sony's FeliCa chips (e.g. FeliCa Lite)
- Tag 4 Type: e.g. NXP's MIFARE DESFire
NFC devices can operate in three different modes based on the ISO/IEC 18092, NFC IP-1 and ISO/IEC 14443 contactless smart card standards.
- Read / Write: NFC enabled phone can read or write data to any of the supported tag types in a standard NFC data format.
- Peer to peer: Two NFC-enabled devices can exchange data. Peer-to-Peer mode is standardized on the ISO/IEC 18092 standard.
- Card emulation: An NFC-enabled phone acts as reader when in contact with tags or act as a tag for existing readers.
NFC devices:
Blackberry Bold 9900
HTC One X
LG Prada 3.0
LG Optimus Vu
Samsung Galaxy Nexus
Samsung Galaxy Note
Samsung Galaxy S II HD LTE
Samsung Galaxy S III

Sony Xperia S

SKU for APP
The Wikipedia explains that:
It is a unique identifier for each distinct product and service that can be purchased. The usage of SKU is rooted in data management, enabling the company to systematically track its inventory or product availability, such as in warehouses and retail outlets. They are often assigned and serialized at the merchant level. Each SKU is attached to an item, variant, product line, bundle, service, fee, or attachment
For our App SKU, just use <com>.<company name>.<product>, it's a little like program namespace.

[Xcode] Use if condition for storyboard segue push
Generally, we use storyboard seque is that drag button to destination view controller.
But if we want to do if some condition to different target view controller, should use another way.
1. Drag source view controller to destination view controller as seque push.
2. Give push identifier name.
3. Put the code [self performSegueWithIdentifier: @"goToDestination" sender: self]; to your button action.
Remember don't forget the identifier.
