Change the installation directory of npm -g

To prevent to pollute the environment, create a local_dir then

npm config set prefix local_dir

or just edit the .npmrc

prefix=local_dir

and set $PATH to include local_dir/bin

export PATH=local_dir/bin:$PATH

Fail to mount Guest Additions in VirtualBox

Just met this problem today and found solution here

sudo apt-get install virtualbox-guest-dkms virtualbox-guest-utils virtualbox-guest-x11

一些 ssh 的設定

參考這篇，有很多把 key 的話，可以設定 .ssh/config 如下

Host github.com
        User git
        Hostname github.com
        PreferredAuthentications publickey
        IdentityFile ~/.ssh/github/id_rsa
Host bitbucket.org
        User git
        Hostname bitbucket.org
        PreferredAuthentications publickey
        IdentityFile ~/.ssh/bitbucket/id_rsa

使用 ssh-agent 可以在 .bashrc 加入以下設定

# ssh_agent
function check_ssh_agent {
    if [ ! -e "$SSH_AUTH_SOCK" ]; then
        eval `ssh-agent -s`
        ssh-add
    fi
}

check_ssh_agent;

如果有多把 key 而且在不同目錄就要在 ssh-add 後面指定要加入哪些 key

用 cat 寫檔

cat > file << EOF

gitolite + http mode + LDAP

gitolite 安裝

參考這邊，將 /var/www 改為想要放置 git repo 位置的目錄

cd /var/www/
mkdir gitolite-home
export GITOLITE_HTTP_HOME=/var/www/gitolite-home
PATH=$PATH:$GITOLITE_HTTP_HOME/bin
cd gitolite-home/
git clone git://github.com/sitaramc/gitolite gitolite-source
cd gitolite-source/
GHH=$GITOLITE_HTTP_HOME
mkdir -p              $GHH/bin $GHH/share/gitolite/conf $GHH/share/gitolite/hooks
src/gl-system-install $GHH/bin $GHH/share/gitolite/conf $GHH/share/gitolite/hooks
vim /var/www/gitolite-home/share/gitolite/conf/example.gitolite.rc
gl-setup ADMIN的LDAP帳號

apache 設定

參考這邊，修改 auth 的部份為 LDAP

<LocationMatch "/git">
     AuthType Basic
     AuthName "Git"
     Require valid-user 


     AuthBasicProvider ldap
     AuthzLDAPAuthoritative off
     AuthLDAPURL "ldap://server:389/dc=company,dc=local?sAMAccountName?sub?(objectclass=*)" NONE
     AuthLDAPBindDN "cn=user,ou=team,ou=department,dc=company,dc=local" 
     AuthLDAPBindPassword secret 
</LocationMatch>

設定gitolite

選擇以後要放設定檔的位置

• git clone http://server/git/gitolite-admin

gitolite.conf 的設定說明，要新增 repo 或是要加入使用者設定都是在這個檔案修改，修改完成以後將 gitolite.conf 更新回 server

• git add
• git commit
• git push origin master

Outlook 2000 設定

Outlook 2000的個人資料夾檔案(.pst)上限是2GB，不幸滿了的時候的處理方法。

來源: http://support.microsoft.com/default.aspx?scid=kb;zh-tw;296088

• 找出電腦裡的Scanpst.exe，我的在 C:\Program Files\Common Files\System\Mapi\1028\NT 目錄中
• 找到過大的.pst檔，檔案位置可由Outlook的工具－服務－個人資料夾的屬性中得知
• 使用Scanpst修復.pst檔後，重新啟動Outlook，通常還是沒用，因為檔案真的太大了
• 下載這個檔案，這個程式是把.pst刪掉一點，讓檔案小於2GB，這樣Outlook就可以讀，刪掉的資料當然就是不見了(註)
• 再次使用Scanpst修復.pst檔，重新啟動Outlook應該就可以正常使用。如果還是不行，就重複上個步驟，讓他砍掉的大小再大一點

上面的方法只是治標，如果你需要留下來的信就是這麼多，.pst檔再次超過2GB是遲早的事。稍微查了一下，治本的方法是把信分成多個.pst檔來儲存(或者是用GMail?)。

把信分成多個.pst檔的方法

• Outlook裡的工具－服務－新增－個人資料夾－選擇.pst檔的位置－設定名稱跟壓縮設定
• 可以把信件搬進新的個人資料夾，或者設定郵件規則讓某些信件進入特定資料夾
• 搬動信件以後，使用工具－服務－屬性－壓縮原本的.pst
• 也可以使用檔案－匯入把.pst匯入新的個人資料夾

註：公司MIS有示範不遺失任何信的處理方法，不過他動作太快了我記不起來
