Java: Use ByteBuffer As InputStream
Sometime, your program may need to read data from a ByteBuffer buffer into a InputStream object. There is no class in Java library that provide the facility to do the conversion.
Anyway, to use a ByteBuffer object as an InputStream is pretty simple. What you need to do is to write a class wrapper that inherit InputStream and override the read() function in InputStream.
Java: Format Integer Into Fixed Width String
Sometime, you may want to format an integer or a long value into a fixed width String. You need to display the value in fixed width especially in reports where you want to keep the numbers in aligned (e.g. 3456 as 0003456 and 1234 as 0001234).
Other than that, you may also want to format the integer value for a better visibility. For example, to display integer value as a document number (e.g. 12345678 as 00-01234-5678), for example an account number.
The Java.format() is not flexible enough to solve my problem. At least it cannot be used to format a fixed length document number in the format I want: XX-XXXX-XXXX. Therefore I decide write my own format function.
Java: Continuously Read Data From FileChannel Without MappedByteBuffer
When programmer writes a program to read data from a file continuously and sequentially with a fixed data type reading sequence (e.g. to read three integers then 2 doubles repeatedly), he or she may find the MappedByteBuffer from Java library is useful.

BigDump: Alternative to phpMyAdmin to Import/Restore Large Database
Recently I was facing problem on restoring database with a lot of data into MYSQL using phpMyAdmin. The restoring process keeps interrupted due to the connection between browser and server time's timeout and also due to the timeout in PHP script. Only partial data is restored and I kept dropping the database, increase PHP timeout, increased memory limit, and tried to restore again. But it still failed.

Wordpress: Catch A Spam Comment With Statcounter
Sometime your Wordpress' anti spam software (e.g. Akismet) may not able to stop all the comment spam because the comment looks too real to it and to human too. In this case, you will need to identify the comment whether it is actually a real comment or it is automatically submitted by software.
Someone who made a comment must have visited your site. That's it, if he or she has not visited your site but his or her comment is posted on one of your post. Then it is very high possibility that the comment is a spam comment.
How do you ensure someone who left a comment on your blog actually visited your site? The best way to do it is by looking at the IP address where the computer submitted the comment.
