Install Windows 7 (ISO) from USB Flash Drive |
||
 |
 |
 |
星期三, 七月 1, 2009, 11:16 Requirement:
USB Pen Drive (Min 4 GB) Windows 7 ISO (32 bit or 64 bit) MBRwiz Download and Extract it on your hard drive (Diskpart utility for Windows XP doesn’t detect USB drive as Disk hence we need to use this free utility to make bootable USB drive). Steps: 1. Format USB Flash Drive 2.Now go to Start Menu->run->cmd (Open Command Prompt) and Type following command convert i: /fs:ntfs (Where “I” is your USB drive latter) 3.(optional, if your usb drive is already active. you can check with MBRwiz /list) In command window, dir to directory where you have extracted MBRWiz and run following commands mbrwiz /list (note down disk number of your USB Pen drive) mbrwiz /disk=X /active=X (X is Disk Number of your USB Drive) 4.Mount Windows 7 iso as drive. In command window, type following command J: (Drive letter of Windows 7 iso mounted with demon tool) CD boot bootsect /nt60 Y: (Y is drive latter of your USB drive ) (if your current OS system is 32bit, you can only try this with 32bit win7, since your system can not run 64bit exe. Then you need a 32bit win7.) 5.Now copy all files from drive where you have mount Windows 7 iso. Done [ 发表评论 ] | [ 0 trackbacks ] | permalink |  ( 0 / 0 ) |

Win XP File Sharing: Access denied |
||
|
|
|
星期二, 六月 23, 2009, 21:53 Just did a clean install of XP on both laptop and desktop. Upgraded to SP3 immediately after installation. They can see each other on the subnet, and the laptop can share file with desktop, however the desktop can not share any file. I got access denied every time when trying to connect with xx.xx.xx.xx.
Checked with net view (pc-name), still got access denied. Enabled/disabled the guest account, tried to grant access for guest in group policy, e.g. open control panel->administrative tools->local security policy->local policies In "user rights assignment->deny access to this computer from the network", remove the guest/everyone from there In "user rights assignment->access this computer from the network", add everyone in there In "Security options->Account:Guest account status"--Enabled In "Security options->network access:sharing and security model for local accounts", change to classic-local users authenticate as themselves. Use XP tool, to set up home network, does not work. But, all these above don't work. I tried again and again, until I tried ntrights command tool (Windows Server 2003 Resource Kit Tools, download from here ), then type net user guest /active:yes ntrights +r SeNetworkLogonRight -u Guest ntrights -r SeDenyNetworkLogonRight -u Guest It worked for me. :D After all, I still have guest account disabled.

[Linux]Flash plugin for x86_64 |
||
|
|
|
星期二, 四月 14, 2009, 16:14 Since Adobe has not officially support x86_64, the alternative way to do is the following.
1.Download flash plugin Also since I still have Fedora 4 which is not supported by the latest flash player 10, I have to download the older one, flash player 9, from here . 2.mv <install-flash-player>/libflashplayer.so <firefox>/plugins/ 2.Install nspluginwrapper 3. nsplugingwrapper ./<firefox>/plugins/libflashplayer.so

星期日, 四月 12, 2009, 23:28 Lesson 101
0.Install Matlab Distributed Computing Server and Parallel Computing Toolbox 1. Start Distributed Computing Server. cd $Matlab/toolbox/distcomp/bin
% under file system (not within Matlab command line) mdce install
% install Matlab Distributed Computing as a service mdce start
2.connect worker to host (local) startjobmanager -name MyJobManager
% start first job manager, the default job manager name is default_jobmanager without specifying by -name startworker -jobmanager MyJobManager -jobmanagerhost phonexitear -name worker1
% -name worker1 must be after the specified jobmanager name(MyJobManager), otherwise it is registered with the default job manager. stopworker -name worker1
% stop worker startworker -clean -jobmanager MyJobManager -jobmanagerhost phoenixtear -name worker1
% with -clean, to clean up all the checkpoint nodestatus -infolevel 3
% check node status, infolevel [1,2,3] admincenter
% verify the installation and configuration of MDCE java.net.InetAddress.getLocalHost.getHostName
% check the hostnames for local machine, cannot run with -nojvm 3.connect worker to host (remote) jm=findResource('jobmanager','lookupurl','REMOTE_HOST_IP')
% find remote job manager by its IP address, use this to check that MDCE service is running, that hostname resolution is correct, or that firewall is blocking port for communication % DNS lookup: nslookup xx.xx.xx.xx % hostname should match with computer name % to open range of ports on firewall under linux iptable -I INPUT -p tcp --dport 27350:27450 -j ACCEPT
% the base port is 27350, the range for N workers is 27350+N % to open range of ports on firewall under windows % in command line FOR /L %I IN (Start_IP,IP_Step,End_IP) DO netsh firewall add portopening TCP %I “(Name of rule)”%I
% to delete the range of ports under windows FOR /L %I IN (Start_IP,IP_Step,End_IP) DO netsh firewall delete portopening TCP %I
startworker -clean -jobmanager MyJobManager -jobmanagerhost JM_HOST -name worker1 -remotehost ClientHost
% start worker on ClientHost and register on JM_HOST (either client or jm is on remote host) [ 发表评论 ] | [ 0 trackbacks ] | permalink | ( 3 / 116 ) |

星期一, 四月 6, 2009, 01:46 没想到还能代表UMN参加全美的大学乒乓球联赛
在米国这块曾经是乒乓的贫瘠之地上,这项运动的组织也是异常的出色 In NCTTA 2009 National Championships, April 3-5, 2009, Rochester MN, final ranking for Minnesota team is the 10th place. It is the best result for us. To me, I am still loving this game even though I thought it was over long time ago. ;)

Intel 855GME vs 1920x1200 resolution |
||
|
|
|
星期三, 二月 18, 2009, 01:04 Tried to configure an external 24' monitor for an old laptop. The native resolution of 24' monitor is 1920x1200, and the graphics of the laptop is Intel 82852/82855 GM/GME chipset, whose specific maximum setting is only 1600x1200. According to Intel's documentation, this chipset can support up to 2048x1536@60Hz, here . However, the Intel driver does not allow such option, as opposed to some ATI/NVidia chipset which is fully supported by its driver.
So is it doable? The answer is yes, and with several options: [1] Use the third party software such as powerstrip , which can fool the driver to setup a higher resolution. [2] The DTD Calculator is an excellent tool. It requires intensive math calculation to configure any desired resolution. Unfortunately, it doesn't support the 855GME chipset. If you have 915GME or 945GME, you should definitely try it. [3] Finally, I found that even though the normal Intel graphic driver doesn't do the work, the Intel Embedded Graphic Driver (IEGD) supports quite a lot resolutions, such as 1920x1200. The supported platforms includes 852, 855, 910, 915, & 945. So it is way to go. The IEGD driver can be downloaded from here . However it is not flawless. In fact, the Fn to switch between the external & internal monitor is disabled, which supposedly is not included in the IEGD driver but the normal one. Moreover if the external monitor is connected when the IEGD driver is installed (assume larger resolution than the internal one), the internal screen would most likely become dark screen after unplug the external monitor, unless the driver is rollback to the original one.
