Ububtu iBus icon disapear 圖示消失

某一天 iBus 的圖示突然消失了，害我心慌慌，雖然仍然可以打字，但是你知道人對於未見的東西總是有恐懼感，而且很不方便。

在網路上找到以下方法‥

killall ibus-daemon （結束程序）
ibus-daemon -d （重啟ibus）

或
ibus-daemon -d -x -r

Update Google Chrome in Ubuntu

參考這裡（ref here )http://superuser.com/questions/130260/how-to-update-google-chrome-in-ubuntu

You must have http://dl.google.com/linux/deb/ in repo list

Now open a terminal. Type following -

sudo apt-get --only-upgrade install google-chrome-stable

This will install the current stable version of it. Now you have to kill all instances (may be hidden) of old Google Chrome.

sudo pkill -15 google-chrome
sudo pkill -15 chrome

Then start google-chrome as you start it.

Ubable to execute dex: Cannot merge new index

[solution on stackflow]

Android Error in Eclipse: “Unable to execute dex: Cannot merge new index 65799 into a non-jumbo instruction!”

One solution that I found that got it working for me was to add dex.force.jumbo=true to my project.properties.

This was pointed out at: https://groups.google.com/forum/?fromgroups=#!topic/adt-dev/tuLXN9GkVas

This is assuming you are running ADT 21 as this feature wasn't available in previous versions.

FIX ECLIPSE (LUNA) DISPLAY ON UBUNTU 14.04

http://www.kaibader.de/fix-eclipse-luna-display-on-ubuntu-14-04/

In case of starting Eclipse from a console two environment variables need to be set in advance to avoid a corrupted Eclipse window:

export SWT_GTK3=0
export UBUNTU_MENUPROXY=0

In my case I created a desktop entry~/.local/share/applications/eclipse.desktop to facilitate the startup. Adapt it to your needs:

[Desktop Entry]
Version=4.4
Name=Eclipse
Comment=Eclipse IDE
Exec=env UBUNTU_MENUPROXY=0 SWT_GTK3=0 /home/kai/eclipse/eclipse
Icon=/home/kai/eclipse/icon.xpm
Terminal=false
Type=Application
Categories=Utility;Application

repo error: syntax error near unexpected token `newline' repo problem

curl https://dl-ssl.google.com/dl/googlesource/git-repo/repo > ~/bin/repo

執行 repo init -u git://android.googlesource.com/platform/manifest.git 可能會出現下面的錯誤

~/bin/repo: line 1: syntax error near unexpected token `newline'
~/bin/repo: line 1: `<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"

可能是下載的 repo 壞掉了。從官方下載的 repo 檔案可能壞掉了，只要重新下載一次就好了。

curl http://git-repo.googlecode.com/files/repo-1.13 > ~/bin/repo

[1]http://blog.csdn.net/kai46385076/article/details/17460563

Update(2016/06/22)
有另一種可能是要將 https 改為 http

REPO_URL='https://gerrit.googlesource.com/git-repo'
改為
REPO_URL='http://gerrit.googlesource.com/git-repo'

解決 Windows 7 啟動時撥號 PPPoE 無效 (使用rasdial)

如果我們想在 Windows 7 開機後想直接撥號 PPPoE 連線，網路上有些教學是將捷徑放到啟動的資料夾內以便啟動
但不曉得為什麼我的就是沒辦法這麼做
首先將連線的「提示名稱」該項取消打勾，再放入啟動的資料夾
如下圖：

結果發現命令是「空的」

難怪怎麼開機都無法自動執行！

於是這裡提供另一個方法

編輯一個新的純文字檔並將它隨意命名，只要副檔名是 .bat 即可

內容如下：

rasdial.exe "你的連線名稱" "帳號" "密碼"

再將這個*.bat放置到

C:\Users\%username%\AppData\Roaming\Microsoft\Windows\Start Menu\Programs\Startup\ 下即可
