Tinsology

I’ve been making some progress on the next version of Apparatus. Along with some bug fixes there are a few new features. One new thing is the option to attach a database to allow for more advanced functionality. For now this includes something I’m calling examples generation, which allows you to store your code and output and allow others to view it. This is done without giving them access to the Apparatus interface. Apparatus can still operate in lite mode (without a database), but some features will not be available.

Also in the works is a new template… Read More

Traditionally, when someone is introduced to programming, the first block of code they write is the infamous “Hello World” program. Unless you’re dealing with some esoteric language this program usually consists of just a few or even a single line. There is one popular language out there where, in comparison, Hello World is a monster: Java. If you’re a Java coder you may not see it, especially if Java wasn’t your first language. Try to look at it from the perspective of a first timer: Read More

As someone who is already experienced with a few programming languages, learning new languages, frameworks, and platforms is a much different process from someone who has no background in programming. Obviously having written a ton of code make learning how to write different code much easier. Much of the documentation out there however does not seem to take advantage of this fact. Documentation for someone who is completely new to programming is the same as documentation for someone with years of experience. It might be easier for the experienced programmer to understand and utilize that documentation, but it is still… Read More

If you are implementing your own user management system you may want to ensure that emails associated with users’ accounts are valid. The most straightforward way of doing this is to send an email to this account and verify that the user received it. Obviously we don’t want to do this manually so the solution is to write a script that automates the process.

High Level Concept
What we will need to do is:

1. Generate a confirmation code for our users are registration time
2. Store that code and track which users are not yet confirmed
3. Send an email

For a while now I’ve been working on a web-based PHP interpreter; an interface I can use to quickly test or develop code from my browser. Ultimately this resulted in Apparatus, an in-browser PHP read-evaulate-print loop. Give it a try: http://tinsology.net/scripts/apparatus/.

Note that this is currently a beta version. Any help with identifying bugs will be greatly appreciated.

P.S. Happy New Year!… Read More

If you’ve spent any significant amount of time coding in PHP you’re most likely familiar with PHP’s foreach loop syntax. In simple terms, a foreach loop is an easy way to iterate over the elements of an array. Chances are if you’re reading this you already know that. What you may not know, however, is that it is possible to iterate objects with a foreach loop. Assuming you have some collection class (an object that stores some number of elements in an organized manner) you can iterate over its elements just like you can the elements of an array… Read More

Anyone who has ever had an email account is probably very familiar with the “Do not reply” email. They can take the form of notifications from your bank, reminders to pay a bill, a newsletter, or just plain spam. Generally the read a little something like:

Please do not reply to this email. This mailbox is not monitored and you will not
receive a response.

Usually this is followed by some instructions to follow if you have a question or concern. I imagine at some point in the history of automated emailers someone decided that they did not… Read More

If you use Opera you’re probably aware that it supports shortcuts in the address bar that allow you to run a search on various search engines and websites. For example, if I type g tinsology in the address bar, you’ll get the Google search results for the keyword tinsology. You can do similar things with yahoo, amazon, ask and other sites that come preconfigured in Opera.

Personally, I find myself frequently using this shortcut to Google PHP documentation. For example if I’m looking up documentation for the implode function, I’ll type g PHP implode. More often than not the… Read More | 3 Comments

I suddenly recall something interesting a professor of mine pointed out a couple years ago while on a tangent during lecture. It has to do with the nature of infinity and how accepting something perfectly reasonable as true leads to less intuitive, but equally true conclusions.

The following expression is true and most people would not argue otherwise:

1/3 = .3333333333 . . .

Assume, of course, that there is an infinite number of 3s trailing the decimal point. The following expression is also true, and even fewer people would argue otherwise:

1/3 +… Read More | 2 Comments
