How to hibernate instead of standby when closing the lid of macbook(pro|air)

Sometimes, we probably prefer to hibernate my mbp instead of make it standby when closing the lid. I am wondering why there is no GUI setting for this simple matter. The only way that I know is by using command pmset from the terminal window as follow:

(1) To enable the hibernate:

$ sudo pmset -a hibernatemode 5

(2) To switch back (standby):

$ sudo pmset -a hibernatemode 0

Or for more detail of pmset command, read the manual (man pmset).

Windows could not start because the following file is missing or corrupt \windows\SYSTEM32\CONFIG\SYSTEM

Three days ago, a friend asked me to recover his laptop (winXP) from the following error which always appeared during booting:

Windows could not start because the following file is missing or corrupt \windows\SYSTEM32\CONFIG\SYSTEM

The solution is straightforward from Microsoft website (http://support.microsoft.com/kb/307545). In brief:
The first step is to gain access to windows OS by replacing the broken registry file with the default registry file (windows installation CD is required). The second step is to copy the latest system restore registry file (hopefully your system restore is enabled) to replace the default registry file.

To be more detail, those steps are done as follow:

1. boot using the WinXP installation CD, select repair


2. after entering the command prompt, manually copy (overwrite) the registry file (SYSTEM, SOFTWARE, SAM, SECURITY, DEFAULT) from C:\WINDOWS\REPAIR\ to C:\WINDOWS\SYSTEM32\CONFIG\ (you might want to backup the original files)


3. restart to save mode.


4. gain access to System Volume Information folder (http://support.microsoft.com/kb/309531/), inside the folder, find sub folder with name _restore {GUID}\RPx\snapshot. For example: C:\System Volume Information\_restore{D86480E3-73EF-47BC-A0EB-A81BE6EE3ED8}\RP1\Snapshot


5. copy the following files from the Snapshot folder to any other folders: _REGISTRY_USER_.DEFAULT, _REGISTRY_MACHINE_SECURITY, _REGISTRY_MACHINE_SOFTWARE, _REGISTRY_MACHINE_SYSTEM, _REGISTRY_MACHINE_SAM. Rename each of the files to DEFAULT, SECURITY, SOFTWARE, SYSTEM, SAM, respectively.


6. boot using WinXP installation CD, select repair


7. after entering the command prompt, manually copy (overwrite) the file from step (5) to C:\WINDOWS\SYSTEM32\CONFIG\


8. restart.


9. finish, or according to the microsoft website, you should try to restore the setting to previous restore point (Start, All Programs, Accessories, System Tools, System Restore, Restore to a previous restore point).

That's all :)

Emulating HASP HL Basic

About a month ago, I was asked to remove the protection of a software (it looks like the software is specially developed --not for public sale) which is using usb key to protect the unauthorized execution.

First of all, I would like to give credit to the reverse engineering team board, even though I never post any message there, but their board contains invaluable information to help me complete this task. Please notice that I share this information only for educational purpose and only as a note for myself. If you have trouble, please don't ask me. Go to the board instead. :)

Gladly, the usb key type is HASP HL Basic, which is simpler to emulate. Here is the step I've done to successfully emulate the usb key:

1. Get the password-1 and password-2 of the usb key
   Tool required: hasploger
   Plug the usb key and run hasploger. Then, execute the protected software. Hasploger will be able to get the password-1 and password-2 of the usb key.
2. Dump the usb key (password-1 and password-2 from step (1) are required)
   Tool required: h5dmp
   The size of the dump file is 719 bytes (hasp.dmp)
3. Create dummy memory file
   Tool required: any, notepad text editor is also possible
   Since hasp HL Basic does not contain memory, create file with any content with size 112 bytes (hhl_mem.dmp)
4. Convert the dump file from step (2) and (3) to registry file to be used by emulator
   Tool required: UniDumpToReg
5. Install emulation
   Tool required: I am using multikey_19.0.2-x86 to emulate the key in vista (32bit). While in XP I am using vbus_0.15.4.
   By using the example of registry file from multikey/vbus, modify the registry file from step (4). Then, install the registry and the emulation tool.
6. Done.

All of the tools are available freely in the internet, however, it takes time to find.

That's all :)

Update #1 (2010/11/03)

I've just realized that I miss-typed when I checked my files,the correct multikey file that I was using is multikey_18.0.2-x86. Probably there's a new update now since it had been months.

How to set NetBeans locale to English

My Windows OS has Japanese language as its default locale. However, I am still having troubles understanding Japanese anyway lol. When I try to install JDK+NetBeans, by defaults it will start with the default locale of my system --that is Japanese. After googling here and there, finally found the way to run the NetBeans in English:

Execute the NetBeans with startup parameter --locale:

netbeans --locale en

or

Edit the configuration files (usually in \etc\netbeans.conf), find the entry started with netbeans_default_options="..." and insert the locale parameter to it:

netbeans_default_options="--locale en ..."

How to merge file dll to exe C#

Today, at work I have to create a demo application using C# to automatically launch IE and open certain URL and modify its form input. Since this task requires SHDocVW and MSHTML components, I have to let dll files accompany the exe file. But there is a requirement that the application shall consist of one single executable. Hence, I have to find a way to merge the dll to executable. Gladly, after searching in the internet, I found that it is very simple.

The step is as follows:

1. Download ILMerge from microsoft site here.


2. Install and copy the ilmerge.exe to windows directory or simply make the PATH to installation directory (to let us execute ilmerge.exe from anywhere)


3. Go to the project properties, Build Events. Assuming the dll files are in the same directory of the Target, enter the following code to the post built even command line:
   

   ilmerge /wildcards /out:$(TargetDir)my-final-app.exe $(TargetPath) $(TargetDir)*.dll
   

To have a better understanding on how to execute ilmerge, I suggest to read the ilmerge.doc which is located in the installation folder.

how to change gimp language setting

After changing some regional and language settings in my vista to Japanese, if I run gimp, it displays unreadable character instead of English. I found this url is very helpful to change the language of gimp (in XP, Linux, and MacOSX):
http://docs.gimp.org/en/gimp-fire-up.html#gimp-concepts-running-language

For vista, it is very similar with XP, example is to use English (en):

1. go to control panel, system, advanced system settings
2. click Environment variables..
3. add new environment variable (click New...):
   variable name: LANG
   variable value: en
4. Ok. Finish.

That's all :)

Cannot display Hidden Folders and Files

If you have just infected by some worm or mallware, probably your windows cannot display hidden folders and files although you already set the hidden files options from explorer.
Copy paste the following text to notepad, and save it (for example: repair.reg), then double click to make changes to windows registry.

How to change ubuntu resolution in Virtual Box

Today, I'm installing Ubuntu 8.04 in Virtual Box, with Vista as the host OS. I'm planning to use it as Qtopia development environment. After the installation is completed, I found that the maximum resolution I could set was only 800x600. After some googling, found the solution as follows:

1. install linux guest additions in virtual box
   1. Select from menu: Devices, Install Guest Additions... Ubuntu will detect a new CD inserted and mount it automatically.
   2. go to the terminal, run the VBoxLinuxAdditions.run as root

      $ sudo /media/cdrom/VBoxLinuxAdditions-x86.run



2. edit /etc/X11/xorg.conf using any text editor you're familiar with.
1. Find section "Device" as follows:

   Section "Device"
           Identifier      "Configured Video Device"
           ...
   EndSection

   Insert additional setting so that the section "Device" will look as follows:

   Section "Device"
           Identifier      "Configured Video Device"
           ...
           Driver            "vboxvideo"
   EndSection

2. Find section "Screen" as follows:

   Section "Screen"
           Identifier      "Default Screen"
           Device          "VirtualBox graphics card"
           Monitor        "Generic Monitor" 
           ...
   EndSection

   Modify value of Device and Monitor, and insert some additional setting before EndSection so that the section will look similar with the following (I set resolution 1024x768 here):

   Section "Screen"
           Identifier      "Default Screen"
           Device          "VirtualBox graphics card"
           Monitor        "Generic Monitor"
           DefaultDepth  24
           ....
           SubSection "Display"
               Depth      24
               Modes      "1024x768"
           EndSubSection
   EndSection



3. Finish, reboot.

pppd segmentation fault

At work, I have to develop an embedded system sh3 with busybox and 2.6.12.6 kernel inside it. It is connected to gsm modem through ttySC1. After shutting down several times and rebooting, the pppd occasionally got segmentation fault. The suggestion from debian bug report solves my problem. It is pretty straightforward: Simply delete /var/run/pppd.tdb file (in my system, it is /var/run/pppd2.tdb).

That's all :)

jwgkvsq.vmx worm/virus RECYCLER folder

To clean up system which automatically creates autorun.inf and RECYCLER folder with jwgkvsq.vmx, download and run this program. After reboot, the system probably will complain about missing dll file. To fix it manually, you can use regedit or msconfig:

Regedit:

1. run regedit.exe (start menu, run: regedit.exe),
2. search the dll file name (CTRL+F)
3. delete the entry which contains the missing dll file. Usually, the entry should be found on registry location: HKCU\Software\Microsoft\Windows\CurrentVersion\Run\

Or MsConfig:

1. run msconfig.exe (start menu, run: msconfig.exe),
2. go to startup tab
3. Uncheck the Startup Item which contains missing dll file on the command.

To clean up the infected flash disk or external disk with FAT file system, simply delete the autorun.inf and RECYCLER folder. But if it has NTFS file system, windows will complain about having unauthorized access to the file and folder. You can use Linux and mount the NTFS volume (probably it must be mounted forcefully with options -o force), then delete them. Live CD such as Ubuntu will do.

That's all :)

Updated:
If the above cleaning process didn't work (somehow, the above process works perfectly on my PC but has no effect on my friend's), scan the system using this tool. After scanning, there are probably some unaccessible files (check the log file). then:

1. find suspicious hidden dll file on \windows\system32\,
2. boot to save mode
3. change the ownership of the file (right click, properties, security, click advanced.. the rest I expect you know how.. ;) ), then
4. change the access permissions for everyone,
5. delete the dll file manually.

Perhaps, step (3) to (5) can be applied to remove the autorun.inf and RECYCLER folder too..

That's all :)

Updated #2:
For those who have trouble downloading from antivirus website, I add mirrors for the antivirus:
(2012/10/4: Sorry, the mirrors are no longer available).

PS. Turn off System Restore and unplug your network before executing the removal tool. Otherwise, the virus might not be cleaned up. And refer to microsoft bulletin here to update the vulnerable patch.

If none of the above methods works for you, perhaps you should try to follow the cleaning process from microsoft knowledge base here.

That's all :)

Updated #3:
If you still got problem, The FAQ about conficker from kaspersky might be helpful.

Zend framework mail: broken kanji

I'm using Zend framework for most of my web projects at work. One of the must-have features is must be able to send email either scheduled routinely using cron or executed manually from the web. Somehow, I found that on certain web based email clients the contents of the email with Japanese kanji is unreadable.

I'm quite surprised that after doing many trial and errors converting the encoding type, the solution is very straightforward. Simply add a line to the header of the email contains MIME-Version information as follows:

$class->addHeader('MIME-Version','1.0');

But I still don't know why it should be added manually.. :S

disable SELINUX? for smbd.log: Error was Permission denied

I've just tried to setup another samba for my new linux vmware (I'm using CentOS running on VMWare player). As I already has several linux vmware with samba, I simply copied the samba configuration from other linux which already running.

But.. to my surprised, from the new linux vmware+samba, I cannot mount the samba directory from windows. Checking /var/log/smbd.log, found the following error message:

[2008/10/18 00:26:32, 0] smbd/service.c:make_connection_snum(911)
'/home/user1' does not exist or permission denied when connecting to [remote] Error was Permission denied

I already checked that the directory /home/user1 did exist, the user for connecting was also already had permission to access. After searching for the solution, it seems the problem is related with security enhanced linux policy (called SELINUX ?). Executing man smb_selinux will explain everything what should be done. Well, since this system is only for development, I'm not concerning much for security. The easiest way IMO is by disabling SELINUX at /etc/selinux/config. lol..

SELINUX=disabled

Internet Explorer cannot open the Internet site http://mail.google.com/mail/

I'm not internet explorer (IE) fanboy, but sometimes I'm still using IE together with firefox. When using IE, if gmail already accessed before, after sign in I often get error message as follows:

Internet Explorer cannot open the Internet site http://mail.google.com/mail/
Operation aborted

The only workaround I found is : by clearing the IE temporary internet files (in IE7: menu Tools, delete browsing history, delete files..), and reload the gmail.

That's all. :)

postgresql ilike for non latin character

I was having problem with insensitive query of non latin character in postgresql. My postgresql version is 8.2.5, with EUC_JP encoding. However, for temporary solution, I'm using workaround as follows.

Suppose you are having table ABCD with field name: FIELD1 which might contain non latin characters, with database encoding EUC_JP. For example, to search word 'keyword' with ilike in FIELD1, use the following sql:

select * from ABCD where convert(FIELD1 ,'euc_jp','unicode') ilike '%keyword%';

Gimp on Vista: svg.exe has stopped working

I've just installed Gimp 2.4.5 on Vista. Every time I run Gimp, there're always error message like this:

svg.exe has stopped working

helpbrowser.exe has stopped working

Checking the detail information, seems there's problem with libxml2.dll ( Fault Module Name: libxml2.dll ). Searching from internet, finally found out the workaround:

As administrator, copy libxml2.dll from the bin directory of installed gimp (default will be c:\program files\gimp\bin ) into c:\windows. And don't forget to backup the original libxml2.dll just in case it is required, by simply rename it into any file name, eg: libxml2.dll.original.


That's all.
