An Eye to the World, an Eye to the Net
Every time I have to set up a new website, or I have to revamp an old one I always find myself with the classic dilemma:
“Which colors should I use?”
If I choose colors randomly the results is not really that interesting, so the main idea is to use a pricipal color and then move on the palette. Today I discovered this amazing tool:

Color Scheme example
Pretty handy.

All the old problems are just not here anymore.
Finally the developer of skype had rolled out a version which is pulseaudio friendly.
The version 2.1 Beta works really well, the CPU is not going crazy and it’s all good.
Just update to the last one. And you can use skype again.

More over there is going to be a new Album from Alice in Chains late in September as well.
Autumn will rock!
How an Hill equation looks like?
What is the behaviour of an alpha function?
well, I have scipy installed, I know the equation, I know how to create an array of points… Let’s crunch some numbers!
Hill’s equation:
n variation
K variation:
Alpha function:
If you interested in this and other amenities check the code in the scipy_ex folder on github.
The Hill equation is in the mathematical functions script..
So if you want to import a bazaar branch into git how do you do that?
Following this amazing tutorial which works in a very cool and smooth way
Check it out!
It was really handy 🙂
I’m writing a report and I had to cite an article from a book. It’s one of this book which every article can also be used as a standalone paper. The problem is that if you use an article record, you will miss the book and if you use the book record, you will miss the article.
How to solve it? Google it! (somebody has already solved it and post it somewhere)
And it is. The solution is to use @incollection:
@InCollection{Doe05,
author = {John Doe},
title = {Dynamic Ambient Paradigms},
booktitle = {Paradigm Gems 2},
pages = {223--233},
publisher = {Addison Wesley},
year = 2005,
editor = {Averell Doe}
}
More BiBTeX tips (where I found this solution) on this page.
If you use LaTeX and sometimes want to override the TeX macro to get your figure right there you can do it.
You can use the exclamation point !
\begin{figure}[!ht]
\begin{center}
\includegraphics[scale=0.50]{image.png}
\end{center}
\end{figure}
However the results is not really nice as when Tex take care to do the layout. So the win-win solution would be to have Tex taking care of the layout, but force it to put all the figure that belong to a section within that section.
Well that’s pretty easy and the command
\clearpage{}
Just does the trick.
If instead you refer to a figure but instead of the number of the figure you can read the number of the section, this is because you have misplaced the caption with the label.
The label has to go after the caption, otherwise it will refer to the section not to the figure.
Right way:
\begin{figure}[htb]
\begin{center}
\includegraphics[scale=0.50]{image.png}
\caption{A wonderful image!}
\label{fig: image}
\end{center}
\end{figure}
Note the relax [htb]. LaTeX will take care of the position for you.
An amazing interesting post about crisis and society collapse from Ugo Bardi on the oildrum.
According to the author the complexity of a society is both a cost and a benefit, but after a certain point is only a cost which will bring the society down.
The “homeostasis” is the process which the complex society use to compensate forces which destabilize the society. This analysis is applied to the Roman Empire, but analogy with our societies are also drawn.
The crisis is very close and we are swimming in it, but we are not able to see the water.
I just discovered that in using pylab you can plot an array or list of number vs the list lenght by default.
Let’s say we have a list of point like [2,2,3,4,5,5,6,10, 23,45,58,42,12]
points = [2,2,3,4,5,5,6,10,23,45,58,42,12]
well to plot this you just have to
pylab.plot(points)
and this is the results:
pylab example
The whole script in python
import pylab
points = [2,2,3,4,5,5,6,10,23,45,58,42,12]
pylab.plot(points)
pylab.show()
The last one is needed to show the window, which will happen automatically if you are running the script using ipython with the pylab option.
I just discovered by chance. I always thought that to plot you need x and y, but of course it’s possible to infer the x if you just one to plot only the points, cause each point in the list has a “Cartesian coordinates” embedded, i.e. [0,2];[1,2];[2,3];[3,4];… etc.
