Jun 1st Children's Day
Friday, June 01, 2007 by HongJunX
Long time not coming here.Today is Children's Day,a new month started...
My paper nearly come out,its name is "Two-stage matrix converter drived indirect torque control of induction motor",hope it will be published and get me graduated successfully.
Actually,these days I am focusing on Ubuntu,which is a Linux distro based on Debian.Ubuntu is considered as the most potential Linux distro among all the famous Linux distros.Nearly half a year,a new version would be published.Now,the version is 7.04,with the name "Feisty fawn".I did get my system upgraded to Feisty fawn last Friday,but today,I did something really really silly:I changed the directory /usr and all its sub directory's mode to 777,then I can not use sudo.When I press ctr+alt+backspace to turn to terminal mode,I found I can not start x-window,system tips said "users do not have the authority to run x-server"."Oh,god",This is really bad news.I have no other idea but turn my head to online help.Under terminal,I had to enter IRC channel.When I described my problem said "What should I do?",a guy relied:"Reinstall",then followed with some ironic words:"What were you thinking about then?". "Oh,god!",I replied and quit as fast as I can,it is a shame,really.I can not forgive myself...Maybe you may wonder why I changed the /usr directory mode to 777,I would say,I was doing some copy and paste work under x-window,I thought if I changed all the directory mode to 777,I could do my all job just by click mouse,no need typing under x-terminal.After this fatal system failure,I know that Linux never forgive those silly people.Maybe you had heard of the famous "#rm /" story...
Oh,really forgotten,Our boss,Mrs Su lead us climbing Yuelu mountain this afternoon.It is a long time that we do not go out for fun together.Actually,I am nervous having meal with my boss every time.How should overcome this barrier of my life?
