O I M Optician

Like any computer technician, I love tools and utilities. I can spend weeks looking for and downloading tools I think I will need someday (kinda obsessive). Now and then when I have to do something specific, like repair a Windows component or speed up a Windows installation, I find that it’s...

I finally figured out what was bogging down my database when searching for products. I had to post this. I have about 220,000 active products in my store seekshopping.com... parse time is at the bottom if anyone wants to checkout the performance.I have optimized so many queries and continue to...

No one had developed a CyberCash module, and I really needed one, so I decided to tackle it myself. I'm glad I can give something back to the osCommerce community. For all of you CyberCash users out there, I hope this allows you to continue using CyberCash through VeriSign instead of having to...

This was originally given to me, by Alex Tulkoff, out of a request I had made, for something to keep the images in their correct proportion regardless of their dimensions. I have seen many requests for this now so I'm going ahead and release this as a contribution.To use this just open the...

For vectors, Y = RUNMEAN(X,M) computes a running mean (also known as moving average) on the elements of the vector X. It uses a window of 2*M+1 datapoints. M an positive integer defining (half) the size of the window. In pseudo code: Y(i) = sum(X(j)) / (2*M+1), for j = (i-M):(i+M), and...

Staker is a 3-D artillery warfare game that was inspired by Tank Wars and Scorched Earth, BASIC games I played many years ago. This is just a beta version, so it doesn't have everything in it that I would like. For instance, there is only one type of terrain to battle on. I wanted to release this...

I installed Microsoft Visual Studio(MVS) 2008 and Matlab R2007b and tried "mex -setup" command from Matlab. However my MVS 2008 was not recognized by Matlab. I debugged mex.m and found a way to show MVS 2008 to Matlab. Necessary files are located at 2 different directories in zip file...

This creates a new figure containing subplots of other currently open figures including all non-colorbar axes in the figure (i.e. including subplots).example: i have figures 12 15 18 open. and I want a montage with 12 and 15 on the first line and 18 on the next.mfig = MontageFigures([12 15 18],...

I threw this together for myself, because I wanted a version of interp with differences 1, 2, and 3 (below). I'm sure it's not as fast as it could be - feel free to comment on any potential improvements, or on any bugs.Differences from MATLAB built-in functions: 1. MUCH faster 2. Extends border...

3 days ago i've posted selective mapping method to reduce PAPR, but i used only 3 phase shifts (10,15 and 20) and that was to show the phase shift effect and how it changes the PAPR value, but now in that simulation i'm concerned more about choosing the optimum phase after trying all the possible...

I designed this function with the clear intention in mind of constructing a (useful) database of refractive index. This is basically a function to organize things and (hopefully) set an standard.The function computes the refractive index using a standard form of the Sellmeier formula (as the ones...

The main file in this package, rsparse.m, creates a sparse array object that is a subclass of MATLAB's native sparse data type, but which is robust against certain bugs and errors (present as of R2009b). S=rsparse(varargin) The I/O syntax and options for rsparse() are identical to that of...

I needed to draw some vertical markers to my plots in GUI, so I checked out Brandon Kuczenski's hline/vline submission. However it doesn't accept axes handle as an input argument.Getting around by switching with 'gca' causes weird behavior due to uncertain timing in GUI. So I reverse engineered...

A totally trivial function that I keep on rewriting in line over and over again. Must be somewhere I'm missing or I'm missing something. Here it is in it's "glorious" entirety (-;---------function h=subplotrc(varargin)% function h=subplotrc(varargin) - extension of subplot% subplotrc(m,n,r,c) put...

I've been a fan of OpenID ever since it first turned up on the web, when they were offering bounties for implementing it in popular web apps. So I'm very happy about the scale of adoption it's achieved, and since I've started seeing places where you can use your OpenID to post comments on blogs...

This little project came to be when I couldn't find a shoutbox that was quite to my liking. I'm no expert with PHP, and the coding is far from elegant, but it seems to work well enough as a shoutbox/guestbook/chat script. I know it could be improved upon. After a couple of people asked if they...

Basically, I wanted to have my comment replies hidden, and have them expand only when I clicked (what's used in this case) a div, using jQuery. So top-level comments are down, but of the comment has children (i.e. has any replies to that specific comment) they would be "folded shut". When you...

NOTE: I am deprecating this module in favor of Ubercart's recurring billing (using Authorize ARB) + role promotion features which essentially accomplishes the same goal of this project.When I started this project this functionality in ubercart wasn't available. I would prefer to put my efforts...

FileField Meta Refresh came about because a host I was using had a limits in place that prevented the uploading of files larger than 40M. To get around this I was submitting a small file with the same filename, uploading the actual file via ftp, copying the file into the system files directory...

The Smart menus, Smart tabs duo of modules make everyone's Drupal experience just that little bit more convenient. The two modules give menus and tabs a memory, so that when you revisit a page, your previous tab or menu choice is already pre-selected for you. Not only will this save you numerous...
