Phải thay đổi chính mình thôi

Bắt đầu từ hôm nay sẽ phải thay đổi chính mình.

Sống vì mình chứ không phải vì người khác nữa.

Lenovo Thinkpad rescue cd disk

http://forum.thinkpads.com/viewtopic.php?t=56398

The Rescue and Recovery - Recovery repair diskette solves this problem.
But for those without a floppy drive, I've created a CD image (ISO) of the diskettes, using a PC with a floppy drive and MagicISO (here's a nice tutorial on how I did it).

Like the above link says:

Quote:

This package creates a bootable diskette that can be used to repair a corrupt boot sector on your primary hard drive. This package can also be used to reenable the F11 function as long as the service partition has not been removed from your hard drive. This package supports Rescue and Recovery versions 1.0, 2.0, 3.0, 3.1, 4.0, 4.1 and 4.2.

Here are the download links (these ISOs were made at the 28th of January of 2007 - check if these really are the latest versions of the repair diskette):

Recovery repair CD for Windows 2000 and XP (rnr31_rrd.exe):
http://rapidshare.com/files/89450678/rnr31_rrd_fixed.iso

Recovery repair CD for Windows Vista (rnr40_rrd.exe):
http://rapidshare.com/files/89450908/rnr40_rrd_fixed.iso



Now burn the ISO image to a CD (using Nero, MagicISO, etc.) and restart your computer with the CD in the drive.
Note: Install the Rescue and Recovery software, before restoring the partition.


When booting from the CD (I only tested with the Vista diskette. I assume the same dialogues will appear with the XP and 2000 one):

You'll probably get a "Write protect error writing drive A: Abort, Retry Fail?" error. Just enter "F" to choose the Fail option (this error will appear several times. Just keep pressing "F" every time it appears).

You'll eventually get to a screen where you should choose the option "Option 1: Repair the current master boot record." (press ENTER).
After a few more Fails, a message saying "repairing... writing new mbr..." should appear. After pressing Fail again, you'll get a message saying "File creation error".
Finally another screen will appear with two option: "Press ENTER and continue" and "Press ENTER and continue" (yes, both options have the same text). CHOOSE THE SECOND ONE! (I lost a bit of time here, because I kept choosing the first option).
You'll see a few more error messages (continue pressing "F") and finally a screen saying "The operation was completed successfully". Press ENTER.
You'll probably get a few more "Fails"... After reaching the DOS prompt ("A:\>"), you can turn off the computer.
Note: Remember to eject the CD, or you'll boot again from it.

Now, when you press the ThinkVantage button you'll have the F11 option or you'll be redirected to Rescue and Recovery.

MySQL Cluster

1.What is MySQL Cluster?
Using
MySQL Cluster is a high-availability, high-redundancy version of MySQL adapted for the distributed computing environment.
It uses the NDBCLUSTER storage engine to enable running several MySQL servers in a cluster.
http://dev.mysql.com/doc/refman/5.0/en/mysql-cluster.html
Tech
MySQL Cluster is a technology that enables clustering of in-memory databases in a shared-nothing system(1).

2. Supported
Linux, Solaris, Mac OSX, HT-UX, and other Unix-style operating systems on a variety of hardware.
Cluster Supported Platforms list
3. Architecture
A MySQL Cluster consist of a set of computers, each running a one or more processes which may include a MySQL server, a data node, a management server, and (possibly) a specialized data access programs.

All these programs work together to form a MySQL Cluster. When data is stored in the NDBCLUSTER storage engine, the tables are stored in the data nodes. Such tables are directly accessible from all other MySQL servers in the cluster.
The data stored in the data nodes for MySQL Cluster can be mirrored.
MySQL Cluster's NDB storage engine contains a complete set of data, dependent only on other data within the cluster itself.
Currently, MySQL does not support multiple data nodes in a single server.

4. Keywords
Shared-nothing system(SN): is a distributed computing architecture in which each node is independent and self-sufficient, and there is no single point of contention across the system

Access HTTPS in Java

javax.net.ssl.SSLHandshakeException: sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target

1. First of all you copy the URL that you are connecting to and paste it in your browser. Let us say you are using IE. Just paste the url in the address bar and press enter.

2. You will now probably see a dialog box warning you about the certificate. Now click on the 'View Certificate' and install the certificate. Ignore any warning messages.

3. Now that the server certificate is installed in your computer, your browser will not warn you when you visit the same site again. But however your JRE dumb as it is does not yet know about this certificate's existence until you add it to its keystore. Usually you will use the keytool to manage certificates. Keytool is a command-line utility with numerous arguments that allow you to create and manage keystores for housing digital certificates. For the complete documentation of keytool,http://java.sun.com/j2se/1.3/docs/tooldocs/win32/keytool.html

4. You can list the current certificates contained within a keystore using they keytool -list command. The initial password for the cacerts keystore is changeit. For example:

C:\Program Files\Citrix\Citrix Extranet Server\SGJC\jre\bin>keytool -list -keystore ..\lib\security\cacerts

Enter keystore password: changeit

You will then see the something like this:

Keystore type: jks

Keystore provider: SUN

Your keystore contains 11 entries:

5. Now you have to add the previosly installed certificate to this keystore. To add, begin by exporting your CA Root certificate as a DER-encoded binary file and save it as C:\root.cer. (you can view the installed certificates under Tools->'Internet Options' ->Content->Certificates. Once you open the certificates, locate the one you just installed under 'Trusted Root Certification Authorities". Select the right one and click on 'export'. You can now save it (DER encoded binary) under your c: drive.

6. Then use the keytool -import command to import the file into your cacerts keystore.

For example:-alias myprivateroot -keystore ..\lib\security\cacerts -file c:\root.cer

Enter keystore password: changeit

Owner: CN=Division name, OU=Department, O=Your Company, L=Anytown,

ST=NC, C=US, EmailAddress=you@company.com

SHA1: B5:C3:BB:CA:34:DF:54:85:2A:E9:B2:05:E0:F7:84:1E:6E:E3:E7:68

Trust this certificate? [no]: yes

Certificate was added to keystore

7. Now run keytool -list again to verify that your private root certificate was added:

C:\Program Files\Citrix\Citrix Extranet Server\SGJC\jre\bin>keytool -list -keystore ..\lib\security\cacerts

You will now see a list of all the certificates including the one you just added.

This confirms that your private root certificate has been added to the Extranet server cacerts keystore as a trusted certificate authority.
