One of the things I think is amazing about VBA is the fact that it is so incomplete in some ways. For instance, did you know that there is no native way to get the local timezone offset. Yesterday I was working on a VBA SOAP plugin for Excel and Read more…
Recently, I have been interested in creating a quick one-way encryption method. After playing around with a lot of different variations, I settled on the following: One nice thing about this function is the fact that you can restrict the encrypted message to a certain length. Another interesting thing is Read more…
Did you know that the bitwise operators always return 32-bit (signed) integers? If you don’t believe me, test out the following examples for yourself:
Recently, I had to create a PostgreSQL equivalent of the Java hashCode() function. In order to do this, I needed a way to make sure that numbers that exceed the INTEGER representation (ranging from -2^31 to 2^31-1) will be wrapped. In JavaScript, this is as simple as using the logical Read more…
The following is a function which returns the chainable version of a function: Here is an example of how to define a pseudo-class which uses this chaining method: Here is an example which shows that the chaining works as intended:
The following prototype function mimics the hashCode() function of java.lang.String in Java: Depending on the version of Java that you are running, what is returned from this function may not be the same thing that is returned in Java. On the other hand, this implementation is computationally equivalent to the Read more…
The following is a quick JavaScript function which will return the reverse of a string: The above function is a function that, once defined, will exist for every string. Here are some examples of how to use the above function: By the way, if you noticed the last two examples Read more…
The following is a quick JavaScript function which can determine if a string contains a substring: The above function is a function that, once defined, will exist for every string. The first parameter, which is the string to be found, is required. The second parameter, which is a boolean specifying Read more…
The following is a quick JavaScript function which can determine if a string starts with a substring: The above function is a function that, once defined, will exist for every string. The first parameter, which is the string to be found, is required. The second parameter, which is a boolean Read more…
The following is a quick JavaScript function which can determine if a string ends with a substring: The above function is a function that, once defined, will exist for every string. The first parameter, which is the string to be found, is required. The second parameter, which is a boolean Read more…
