实时同步虚拟机的系统时间

虚拟机(比如VMWare)的系统时钟会比正常时钟跑得快, 需要同步成标准时间, 否则有些要检查timeout的函数不能正常工作, 比如检查cookie, session是否失效.

 

实时同步系统时间的做法如下:

1.  sudo vi /etc/crontab

2.  添加下面加粗的行, 成为一个每分钟执行的cron job.

# run-parts
01 * * * * root run-parts /etc/cron.hourly
02 4 * * * root run-parts /etc/cron.daily
22 4 * * 0 root run-parts /etc/cron.weekly
42 4 1 * * root run-parts /etc/cron.monthly
*  * * * * root hwclock –hctosys 2>/dev/null >/dev/null

3.  重启crontab :  sudo service crond restart

A very useful tool – Newtork Port Forward

Port forwarding is where you connect to a port on a gateway machine and it automatically forwards you to another port on another machine. It can be useful in a very wide range of situations, including bypassing firewalls or redirecting traffic from a public network to a private network (or vice-versa).

让Firefox记住任意网站密码 & 让Firefox自动修改新密码

有的网页中给<input>加上了 autocomplete=off, firefox就不会记住用户输入的内容. 

要让 Firefox 记住任意网站密码:

1) Windows 用户：找到 C:\Program Files\Mozilla Firefox\components\nsLoginManager.js

2) 然后搜索 _isAutocompleteDisabled，将 "return true;" 修改为 "return false;"



  修改后, 如下图所示:

3) 重启Firefox.  以后更新到新版本的Firefox, 需要重新做相应修改

 

Firefox会弹出一个对话框, 询问是否将记住的旧密码修改为新密码, 一般我们都会选’修改’.

让Firefox自动修改新的密码:

1) Windows 用户：找到 C:\Program Files\Mozilla Firefox\components\nsLoginManagerPrompter.js

2) 查找  this._showLoginNotification(aNotifyBox, "password-change"

    将相关行注释掉, 并加上  "pwmgr.addLogin(aNewLogin);"  

  修改后, 如下图所示:

3) 重启Firefox.  以后更新到新版本的Firefox, 需要重新做相应修改.

Figured out how to sync Notes calendar with Nokia phone calendar

It’s very very easy and convenient to sync Notes calendar with Nokia phone calendar using Nokia PC Sync in Nokia PC Suite(a free tool).  Nokia PC Sync can save the password for Notes id, and automatically sync calendars entries, contacts, emails etc. when my Nokia 5800 is connected to my laptop via USB cable or BlueTooth.

 

Also IBM provides Lotus EasySync to sync Notes with mobile device.

 

Nokia had done very good phones and very good jobs.  Jobs’ Apple had done very good strategy and ecosystem, but will rot off without Jobs.

IBM Systems Director 6.2 startup becomes much faster

The recently released IBM Systems Director 6.2 becomes much much faster when startup.

Director 6.1 takes about 10 minutes to become “Active” status after running  smstart on a 2G Mem/2.6G Dual core x86 Linux.  Now Director 6.2 only takes about 5 minutes. Great performance improvement!
