## Creating a Gantt Chart for your Project for Free

Today I wanted to work on the schedule of a project with the proper dependencies. More or less, I had the project tasks laid out as a long list (As I would if I were the only one to work on said project) and I needed to answer two main questions:

- How much will it cost?
- How many resources do we need?

The other question, which is always really hard to answer as a software developer, was: * Can you make it happen in 6 months?* But you know the answer to that one:

*(and 6 months later:*

**Of Course!****!)**

*Not*So, I remembedered seeing a manager using MS Project which is what it is. In ...

## ASCII Art Pony

Isn't that cool?

I just find it really facinating that some people have an eye to draw anything with anything (in this case, a little pony with wings using just ASCII characters.)

Have you ever tried to come up with a drawing of your own that would look as good as this one?

## Getting a Proper Random Number on a Computer

99.9% of the time, I see people using random number generator in their software.

Say you have a random function **b()** that generates random bits. Each time you call **b()**, you either get 0 or 1.

Now, in most cases people are going to get a larger number, say you write a function **r()** which returns 8 such bits. You could write it like this:

int r() { return (b() << 7) | (b() << 6) | (b() << 5) | (b() << 4) | (b() << 3) | (b() << 2) | (b() << 1) | (b() << 0); }

Assuming you have a ...

## Some Math

The mean of a set of values [math](x_1, x_2, ..., x_n)[/math] is often represented by [math]\overline{x}[/math]. The calculation of the mean is:

[display]\overline{x} = \mu = {\sum_{i=1}^n x_i \over n}[/display]

The mean may make use of weights (p):

[display]\overline{x} = \mu = {\sum_{i=1}^n x_i p_i \over \sum_{i=1}^n p_i}[/display]

You may want to normalize your weights, which means that their sum will equal 1, with the following:

[display]w_i = {p_i \over {\sum_{j=1}^n p_j}}[/display]

With normalized weights, you can simplify with the following:

[display]\overline{x} = \mu = ...

## Very Difficult Game of Shinsen-Sho

I like a game of Shisen-Sho once in a while. Usually, it's pretty easy. I may have to try 2 or 3 times, but I finish those games fast.

This one, though, it was way harder and it took me many tries before succeeding. But it worked. After a while and many attempts, I finally resolved it.

Unfortunately, the game does not allow us to save the game, I'm wondering whether the author would be willing to offer such an option at some point. I guess I have to post an issue asking such if it's not already available in the latest version.

There is the game as a screenshot (Click to ...

## Solve a in a power n equal b

Finding the value of **a** in equation (1):

a^{n} = b |
(1) |

can be resolved using logarithms.

First, transform equation (1) to equation (2):

ln(a^{n}) = ln(b) |
(2) |

Now we can easily extract the power (n) by changing it into a multiplication:

n × ln(a) = ln(b) | (3) |

From equation (3), we know what the logarithm of a is equal to:

(4) |

Finally, we can write an equation as a = *something*.

## About Radon Gas

I learned about Radon gas as I'm now working in Real Estate at Diverse Realty.

The gas reacts quickly and when that happens it emits some radio active energy. If you are close by, you will therefore be radiated.

We have found, over time, that a small amount of radiation is good for us. Not only that, we actually emit radiation ourselves. More than what Radon gas in our homes generates.

Actually, a smoke alarm system makes use of a decaying bit of radio active material. Those rays go in all directions for a long time.We channel a certain amount in two specific tubes, one of which is ...

## I visited your website...

Every single day I receive an email that tells me they visited my website. There is the one for today:

*« I recently visited your website and wanted to comment on how nice it looks. »*

What I find really interesting is that I manage something like 20 websites and they NEVER tell me which website has a problem. It's like those telemarketers who call you telling you they can fix your credit credit card and immediately tell you there is nothing wrong with it... (you bet, they are always $0 since otherwise you pay a whooping 27%+ interest, who in their right mind would accept such ...

## SMS From Me

SMS From Me is a new service by Made to Order Software Corporation.

This service lets your marketing funnel send SMS from YOUR phone to your prospect.

What SMS From Me offers is a way to send SMS messages to your prospect directly from YOUR phone. This means it is starting a two way conversation with your leads without any intervention from you until your prospect replies to that first text ...

## Create an area that ends with in a triangle

I wanted to create a website header where a background is a large quadrilatere that ends (bottom) with a triangle. So the top is like a rectangle and the two points at the bottom are not at the same level (one is higher than the other, the Y coordinate are different.)

It took me some time on how to do that without using multiple images or multiple divs, etc. And really to make it work cleanly we need an image as a background.

So the image should be large enough for a full screen desktop (crazy big for some these days, mine was big for a while at 1920x1080, now it's a dwarf, right?! ...
