Pentium works on Windows and Intel Pentium class and AMD CPUs to determine the CPUID information such as the vendor, brand/model, step, model, instruction set family, cpu serial number, and the RDTSC Time stamp register for high resolution timing measured in CPU cycles since the last boot. It is designed to be incorporated in your own Java progams. You can also use it as a standalone utility.

The CreditCard Validator will help you tell: (1) if a credit card number is valid (2) which credit card vendor handles that number. It validates the prefix and the checkdigit. It does *not* contact the credit card company to ensure that number has actually been issued and that the account is in good standing. It will also tell you which of the following credit card companies issued the card: Amex, Diners Club, Carte Blanche,Discover...

Includes classes to let you copy, download and upload files from within a Java program. Also contains a command-line utility to download files. Fully commented Java source is provided. It is now comes in four parts, MiniFileTransfer, FileTransfer and MaxiFileTransfer, Download depending on how much functionality you require. Now supports copying members in local jar files. Usually you embed these classes in your own program.

Base64 is a freeware way of encoding 8-bit characters using only ASCII printable characters similar to UUENCODE. UUENCODE embeds a filename where BASE64 does not. You will see BASE64 used in encoding digital certificates, in encoding user:password string in an Authorization: header for HTTP. The spec is described in RFC 2045. For more details see http://mindprod.com/jgloss/base64.html

Java class library to read and set Windows file/dir times from Java: Create/LastModified . Create time is when the file was first written. LastModified is when the file was last written. Accessed time is when the file was last read or written. Uses JNI native Code. See FileTimes.java for the API to use these methods in your own programs. FileTimes does nothing by itself, other than a debugging test harness to demonstrate the methods.

Fast string search (indexOf) using the Boyer-Moore algorithm. Incorporate this class into your own Java programs to rapidly search strings. Boyerr-Moore is about twice as fast as String.indexOf when the string you are searching in is 2K or over and the pattern you are searching for is 4 characters or longer.

Applet to list all supported encodings (character sets) supported by your browser/java. To install, Extract the zip download with Winzip, available from http://www.winzip.com (or similar unzip utility) into any directory you please, often C:\ -- ticking off the "user folder names" option. To run as an application, type: java -jar C:\com\mindprod\encodings\encodings.jar adjusting as necessary to account for where the jar file is.

Java classes to include in your own programs. They let you read or write a file in one fell swoop into RAM. It also includes createTempFile method that is more convenient to use than Sun's File.createTempFile. It also includes PrintWriterPlus that converts linefeeds to platform specific line feeds even when they are embedded in data. Why the three linked ball logo? It symbolises processing a file in line-sized chunks.

Sound lets you mathematically create sounds in Java. You define your sounds in terms of 16-bit linear code for the waveform, -- an array of samplings. The U_Law.class will then convert that to (or from) *.AU mu-law 8-bit encoding format which you can then play with AudioPlayer.player.start(bis) in an application or with Applet.getAudioClip in an Applet. This is just a sample program. You would insert your own mathematical functions.

In Java, allows you to find out where the mouse in on the screen, even when it is not over one of your apps. This has similar function to MouseInfo.getPointerInfo in Java 1.5+. This class will work in any version of Java. It uses JNI and a DLL, so it only works on Windows. You must install the nativemouse.dll somewhere on the path.
