隻手有漂水味，水不能除味

-
當記得在2003年香港爆發禽流感時，我便參與在教會大潔淨的行動中。完後雙手充滿著漂水味，用幾多的水和梘液也不能除去難聞的漂水味，只是除去很少。那日大潔淨後，回家我也自我大潔淨一番，怎料漂水味突然大減，沒有似的。水和梘液不能除去難聞的漂水味，還會有什麼。原來是洗頭水，一個酸，一個鹼，而產生了中和的作用。不知這化學作用對雙手有沒有影響呢？

Save Settings for TeamViewer Portable

-
Work with TeamViewer.ini situated in \TeamViewerPortable\App\teamviewer folder. Setting nosave=0 will save your settings, but in the registry, and that doesn`t make it portable. The thing to do is importsettings=1 wich activate the automatic settings import. TeamViewer Portable will import the settings from a file called tv.ini which has to be situated in the same directory as your TeamViewer.exe. You can create the tv.ini by exporting your settings in the advanced options of the full TeamViewer version (Extras > Options > Advanced > Show advanced options > Export settings for TeamViewer Portable). This works in the oficial portable release from TeamViewer.com. In the PortableApps.com release, tv.ini must be situated in \TeamViewerPortable\App\teamviewer folder. Also, by setting LogOutgoingConnections=1 in the TeamViewer.ini file you can force TeamViewer to write a log file with detailed information about your connections. This log file is used by the TV Manager...

Windows 7 / Windows Search 4 does NOT support UNC network location indexing

-
WDS v3 gets the support, but Microsoft has disabled the support of UNC indexing in WDS v4, even the Windows Search in Windows 7. There're a lot of discussion about how to overcome this step-down functionality ( http://social.technet.microsoft.com/Forums/en-US/w7itpronetworking/thread/afb904c1-1c61-4aae-b6b1-5cf525b9f8de/ ). There is a simple way. Go to  http://www.microsoft.com/download/en/details.aspx?DisplayLang=en&id=3383  to download a patch called UNCFATPHInstaller.msi . Although the KB states that the patch works only for Windows Server 2003, Windows Vista and Windows XP, it actually does work for Windows 7. After patching, the WDS v4 will recognize OTFS protocol handler, as seen in HKEY_CLASSES_ROOT. You could now specify indexing location in Group Policy, which format stated in ( http://technet.microsoft.com/en-us/library/cc732491(WS.10).aspx ) Please noted that the patch only supports 32 bit.
