Celsius to Fahrenheit

If you just want to convert temperatures by using a website, you should visit the online celsius to fahrenheit conversion tool. Otherwise, keep reading…

This is a very tiny and simple application I’ve written to teach the basic usage of wxWidgets as an introduction to GUI (Graphical User Interfaces).

Its purpose is just what it’s name says: converting from celsius degrees to fahrenheit degrees (and sideways).

Attendance Control

“Attendance Control” is a console application made as an exercise to integrate the different C++ concepts taught in class up to the middle of the year.

The main objective is to be able to develop a employee attendance control which records the times (and justifications, if corresponding) of each time the employees arrive, go to lunch, return from lunch and go back to home.

WP-No-Format WordPress Plugin (Prevent HTML Code Formatting/Modification)

For the ones used to work with WordPress editor’s HTML mode and hate when it creates <p>s and reorganize <br/>s on its will (among other things), I’ve made this plugin.

I’ve been searching a lot for this kind of functionality and, since I couldn’t find any plugin which let you decide which parts of the code you’d want to leave “unformatted”, I started to write my own…


It’s very simple to use. After activating it, you can just type:

<!-- noformat on -->

on the WordPress editor, just before the part you want to protect, and from that point on, WordPress won’t touch the HTML code you write.

If you want to resume the standard “formatting” you have to type:

<!-- noformat off -->

And that’s all!

GNU GPL v3 WP-No-Format is licensed under the GNU GPL v3 (attached)…

Update (version 1.1): added convert_chars function support. Before, some characters got converted to HTML entities (for example, when writting “&&” appeared as “&#038;&”). [Update recommended]

Here is the change log.

Latest WordPress version tested with: 2.8.4

UpTime (How much time has the computer been powered on)

With this tiny tool, you can know how much time has the computer been powered on…


GNU GPL v3 UpTime is licensed under the GNU GPL v3 (attached)…

As usual, here are the links…

For the ones who want to easily read the relevant code:

DWORD dwMilliseconds = GetTickCount();

int nSeconds = (dwMilliseconds/1000)%60;
int nMinutes = (dwMilliseconds/1000/60)%60;
int nHours = (dwMilliseconds/1000/60/60)%24;
int nDays = dwMilliseconds/1000/60/60/24;

char pszStr[256];
sprintf_s(pszStr, 256, "%d days, %d hours, %d minutes and %d seconds", nDays, nHours, nMinutes, nSeconds);

MessageBox(NULL, pszStr, "UpTime 1.0 by NeoEGM <>", MB_ICONINFORMATION);

Guitar Trainer

Guitar Trainer is a program I’ve written to make easier the learning of the position of the different notes in the guitar fretboard. There are lots of features pending to be implemented (including sound, different scales, guessing game by position and by sound, etc.), but it’s quite useful with its current functionality.

The smart right foot

Some days ago, I got an e-mail which stated that there was a challenge which couldn’t be beaten.

The instructions were quite simple:

1- While sitting at your desk, lift your right foot off the floor and make clockwise circles with it.
2- Now, while doing this, draw the number “6” in the air with your right hand. Your foot will change direction!

After breaking my mind for some attempts, I finally found that if you try starting from very low speeds, you can master it!

Anyway I found it quite interesing to be shared :)
As always: practice makes perfect… (Without getting maniac, of course!)

Now start trying!

PHP random password generator

As a new sequel to the Excel random password generator and the Random password generator, I’ve made a PHP random password generator service…

You can call it this way (if you hover the parameter values, you’ll get an explanation):

So, for example, to generate a 10 characters numeric password you could access:

Excel random password generator

Sometimes you may have to generate automatically different random passwords. This could be a very easy task if you just had an Excel function like “RandomPassword”, so you could write:


And get something like:


Well, this is exactly the idea of the Add-In I’ve made…
