Comuptex 2012

這次的Computex show 中Micorsofte主要是強打windows 8系統的 Ultrabook, Tablet , AIO(All in One) PC,
主要大廠ASUS , Acer, Compal, Gigabyte, MSI, Samsung ...等都有展出,
除了這些來看看其它有趣的東西吧.

互動感十足的販賣機, 原本以為是單純的transparent panel 播放動畫,
沒想到是touch panel還可以玩game, AUO的面板,
當然這麼大的面板用的是光學觸控(Optical touch).
 

LITEMAX(晶達光電) 的 Spanpixel Resizing LCD透過獨特的面板切割技術, 提供非一般標準比例的LCD顯示器.
做為特殊工業應用, 車站、購物中心，公共資訊...等的顯示應用.
今年掛牌上市的公司, 電子廣告看板模組似乎有不錯的潛力.

讓我想到Always Innovatin 的 HDMI Dongle
家裡的舊電視只要有HDMI port就可以升級成SmartTV,
後來得知國內有几家公司有在做類似的產品, 似乎也是不錯的商機.

Genius 在2011年推出全球首款Ring Mouse, 今年又推出新一代的Ring Presenter.
用的是2.4GHz無線.

Rabbichant 2.0

規格如下:

精傑電子, 主要強調3D graphic處理能力, 應用在3D presentations, 用transparent panel.
總覺得與磐儀科技推的行動醫療平板很像.

手上拿的是Google Glass ?!
記得CES show中的demo有看過這眼鏡, 暫時找不到之前youtbe上的影片..~"~

G. SKILL

ADATA

玩佷大, 液態氮都出場了.

 如果是在Shopping Mall, Pub..等地方, 應該會吸引不少目光.

萬里科技的號稱全球第一台免去背拍照系統,
不過上面這model 看起來笑的有點僵,
這姿式還有笑容可是要維持3分鐘以上吧, 我猜!!
因為要拍20個角度...冏

看似不錯的功能,
但如果是桌機的話, 雖然灰塵不卡在CPU散熱片上, 似乎依舊在機殼裡面?!

拿D3來展示gaming performance讓我嘴角上揚了一下,
為什麼不拿個3D game來展示..只能說D3正夯...XD

另外Grand Hyatt show room list.

RC version of a program.

Ref. What is an RC version of a program?

Release Candidate, it means its a candidate for a final (official/finished) release of a program.
programs usually go Alpha>Beta>RC>Final.
alpha should be considered badly buggy.
beta should be considered buggy.
RC should be considered stable but may have some small bugs in it.
final is the final product (but not the last version ever).

Alpha's & Beta's (especialy Alpha's) are usually hidden or kept private to avoid normal people from using them to avoid support/troubleshooting problems since there pre-releases

these are development steps/phases, its for planning when they can release the finished version of that program
you could go thought 5 Alpha's, 3 Beta's & 1 or 2 RC's
its to iron out bugs & make sure the features the developers want are in it & in it stabily.

uClibc and Glibc Differences

Ref:

Glibc_vs_uClibc_Differences.txt 

uClibc v.s. glibc 

Glibc, uClibc, Newlib 

uClibc and Glibc are not the same -- there are a number of differences which
may or may not cause you problems.  This document attempts to list these
differences and, when completed, will contain a full list of all relevant
differences.


1) uClibc is smaller than glibc.  We attempt to maintain a glibc compatible
interface, allowing applications that compile with glibc to easily compile with
uClibc.  However, we do not include _everything_ that glibc includes, and
therefore some applications may not compile.  If this happens to you, please
report the failure to the uclibc mailing list, with detailed error messages.

2) uClibc is much more configurable then glibc.  This means that a developer
may have compiled uClibc in such a way that significant amounts of
functionality have been omitted.

3) uClibc does not even attempt to ensure binary compatibility across releases.
When a new version of uClibc is released, you may or may not need to recompile
all your binaries.

4) malloc(0) in glibc returns a valid pointer to something(!?!?) while in
uClibc calling malloc(0) returns a NULL.  The behavior of malloc(0) is listed
as implementation-defined by SuSv3, so both libraries are equally correct.
This difference also applies to realloc(NULL, 0).  I personally feel glibc's
behavior is not particularly safe.  To enable glibc behavior, one has to
explicitly enable the MALLOC_GLIBC_COMPAT option.

4.1) glibc's malloc() implementation has behavior that is tunable via the
MALLOC_CHECK_ environment variable.  This is primarily used to provide extra
malloc debugging features.  These extended malloc debugging features are not
available within uClibc.  There are many good malloc debugging libraries
available for Linux (dmalloc, electric fence, valgrind, etc) that work much
better than the glibc extended malloc debugging.  So our omitting this
functionality from uClibc is not a great loss.

5) uClibc does not provide a database library (libdb).

6) uClibc does not support NSS (/lib/libnss_*), which allows glibc to easily
support various methods of authentication and DNS resolution.  uClibc only
supports flat password files and shadow password files for storing
authentication information.  If you need something more complex than this,
you can compile and install pam.

7) uClibc's libresolv is only a stub.  Some, but not all of the functionality
provided by glibc's libresolv is provided internal to uClibc.  Other functions
are not at all implemented.

8) libnsl provides support for Network Information Service (NIS) which was
originally called "Yellow Pages" or "YP", which is an extension of RPC invented
by Sun to share Unix password files over the network.  I personally think NIS
is an evil abomination and should not be used.  These days, using ldap is much
more effective mechanism for doing the same thing.  uClibc provides a stub
libnsl, but has no actual support for Network Information Service (NIS).
We therefore, also do not provide any of the headers files provided by glibc
under /usr/include/rpcsvc.

9) uClibc's locale support is not 100% complete yet.  We are working on it.

10) uClibc's math library only supports long double as inlines, and even
then the long double support is quite limited.  Also, very few of the
float math functions are implemented.  Stick with double and you should
be just fine.

11) uClibc's libcrypt does not support the reentrant crypt_r, setkey_r and
encrypt_r, since these are not required by SuSv3.

12) uClibc directly uses kernel types to define most opaque data types.

13) uClibc directly uses the linux kernel's arch specific 'stuct stat'.

14) uClibc's librt library currently lacks all aio routines, all clock
    routines, and all shm routines (only the timer routines and the mq
    routines are implemented).

SCHTASKS command.

Ref. Windows CMD commands

Create, delete, edit, list, start or stop a scheduled task.
Works on local or remote computers.

Syntax:

   SCHTASKS /Create [Connect_Options] create_options

   SCHTASKS /Delete [Connect_Options] /TN taskname [/F]

   SCHTASKS /Query  [Connect_Options] [/FO format] [/NH] [/V]

   SCHTASKS /Run [Connect_Options] /TN taskname
   SCHTASKS /End [Connect_Options] /TN taskname

   SCHTASKS /Change [Connect_Options] {[/RU username] [/RP password] [/TR taskrun]} /TN taskname

 Connect_Options:
     /S system                      #remote system (default is local)
    [/U username [/P password]]     #submit job under this name

 create_options:

    /TN taskname /TR taskrun        #Name and pathname for task
    /ST starttime                   #HH:MM:SS (24 hour)
    [/SD startdate] [/ED enddate]   #start and end date "dd/mm/yyyy"

 options:
    /F    Force delete, ignore warnings even if the task is currently runnning.
    /FO format  Output format: TABLE, LIST, CSV
    /NH   No header
    /V    Verbose output

Examples:
Create a task to run at 11 pm every weekday
SCHTASKS /Create /SC weekly /D MON,TUE,WED,THU,FRI /TN MyDailyBackup /ST 23:00:00 /TR c:\backup.cmd /RU MyDomain\MyLogin /RP MyPassword Now delete the task:
SCHTASKS /Delete /TN "MyDailyBackup" /f
