“ Phylotaxis (Phyllos - leaf, Taxis - order) is an exploration of the space where science meets culture. Its structure, derived from the Fibonacci Sequence and closely related to the Golden Ratio, is one of nature's most elegant. The Fibonacci Sequence is the set of numbers where each number is the sum of the previous two numbers. This simple sequence governs phenomena as diverse as the petal arrangement of roses, the breeding patterns of rabbits, and the shape of our galaxy.”

“ The voyage of HMS Endeavour (1768-1771) was the first devoted exclusively to scientific discovery. The Botany Library at the Natural History Museum holds all of the surviving botanical artwork from Captain James Cook's first Pacific voyage. Represented are works of the artists Sydney Parkinson (1745-1771), John Frederick Miller and Frederick Polydore Nodder, among others. These artists' works feature in the finished watercolours made during and after the voyage, between 1773 and 1784. Of the three, only Parkinson sailed on the ship and it was he who made the first sketches of the plants which were encountered and collected.”

Powering Up, One Step at a Time
“ British engineers are converting street vibrations into electricity and predict a working prototype by Christmas capable of powering facility lights in the busiest areas of a city. “We can harvest between 5 to 7 watts of energy per footstep that is currently being wasted into the ground” says Claire Price, director of The Facility Architects, the British firm heading up the Pacesetters Project. “And a passing train can generate very useful energy to run signaling or to power lights.” Like solar and wind proponents, vibration harvesters argue that abundant, clean energy is all around us and goes to waste. The challenge is how to store the power efficiently so it provides a continual output even if the vibrations from footsteps or passing trains temporarily taper off.”
I don't really know how feasible vibration harvesting is but I agree with any research for alternative forms of energy.

Object Oriented Javascript:
- Private, public and privileged members
- One core thing about JavaScript that tends to confuse people is how to get private, public and privileged members.
- Namespacing your JavaScript
- Perhaps a very uncommon approach to developing web applications that require JavaScript (but should be more common) is namespacing your scripts.
- Private Members in JavaScript
- JavaScript is the world's most misunderstood programming language. Some believe that it lacks the property of information hiding because objects cannot have private instance variables and methods. But this is a misunderstanding. JavaScript objects can have private members.

“ My heart feels heavy as I present these portraits of the poorest of the poor of India. My father documented these portraits, not for the Internet, not for the money or artistic effort, but with a sense of history in his mind. “In a few years, it will be hard for us to believe that we lived amongst people like these” he once wrote to me. The subjects in this series are mostly uneducated, poor, and never been in front of a camera.”

Albert Einstein and meandering rivers
“ I begin with a little experiment which anybody can easily repeat. Imagine a flat-bottomed cup full of tea. At the bottom there are some tea leaves, which stay there because they are rather heavier than the liquid they have replaced. If the liquid is made to rotate by a spoon, the leaves will soon collect in the center of the bottom of the cup. The explanation of this phenomenon is as follows: the rotation of the liquid causes a centrifugal force to act on it.”

Stunned Net Art Open 2006
“ The Net Art Open takes a different approach to the curation of Net Art online. Rather then present a single event based exhibition selected by a curator or panel of selectors the Net Art Open is an ongoing blog based process delivered by RSS feed. Curatorial bias has been removed by accepting all work which meets the criteria The result is a true reflection of the state of Net Art now.”

Designing the new layout of my site, I also decided to soften the colors a bit. I'm still using just Blue, Red and a touch of Grey, plus the White background and the Black of text. This were the colors used in the previous version:

And this are the new ones:

Basically, I softened the blue (from #0000ff to #3366ff) and substituted the black(#000) with a grey-black(#333).

On Nature: Sun helps clean the sky
“ The cleaning agent responsible is the hydroxyl radical (denoted OH), which is created when ultraviolet radiation splits apart a molecule of ozone to produce oxygen atoms that subsequently react with water. The resulting hydroxyl radicals are highly active and quickly react with trace atmospheric gases, such as the pollutant carbon monoxide, which is rapidly turned into carbon dioxide.”

On the BBC: detainees to get Geneva rights
“ All US military detainees, including those at Guantanamo Bay, are to be treated in line with the minimum standards of the Geneva Conventions.”
“ Daniel Dell'Orto, a defence department lawyer who was the first to testify, said there were about 1,000 detainees in US military custody around the world.
Guantanamo Bay holds an estimated 450. Mr Dell'Orto did not say where the others were being held.”
“ The new Pentagon policy applies only to detainees being held by the military, and not to those in CIA custody.”

Second post about the new layout.
The sidebar used to contain links to news and most visited (by me) web design sites, links to the categories of my posts, monthly and year archives, a search posts form and the “metadata” (rss, xhtml and css validation, email contact, web hosting).
Since I have a whole page dedicated to external links, I decided to keep in the sidebar only those internal to my web site. I moved the “metadata” into the footer and the fragments links into the sidebar together with the Delicious and Technorati search forms. I think the navigation is clearer now and the sidebar more efficiently organized.

On Digital Web Magazine: accessible widgets for the web
When building web applications, we're working with a fairly restricted set of widgets, compared to those available for native desktop apps. The recent surge of interest in JavaScript points to a solution: we can replicate the functionality of sophisticated native widgets through some clever DOM scripting, and provide our users with exciting interfaces that bridge the gap between native apps and web apps.

On A List Apart: automatic magazine layout
Auto-resized images are a common feature on the web now. Automating the process of resizing images saves a lot of time - it's certainly quicker than manually resizing images in Photoshop - and is a good way to manage images on a site.
Once you have ten or so images, you are better off using an AJAX based image gallery, but this script will fill the gap nicely up until that point.

The sudoku of the 17th century: Sangaku

“ Perhaps it's not surprising that sudoku - the number puzzles that everyone seems to be working on these days - first became popular in Japan before spreading across the ocean. The fad is reminiscent of a math craze that swept the islands centuries ago, when ardent enthusiasts went so far as to turn the most beautiful geometrical solutions into finely illustrated wooden tablets, called sangaku, that adorned the walls of local temples and shrines.”

For some reason it seems that this business fundamental is lost on most business owners.”

This is the first post about the new layout.
At the beginning I wanted to have the latest post bigger and the previous four in a column below, with two more columns beside it, one for the categories and fragments, the other for the archives:

I like it, it's compact and easy to grasp. No fancy positioning and not too much clutter but..the problem, for me, is that there is only an excerpt of the previous posts, to read them it's necessary to click and go to the respective permanent link. I think it's better to read at least the first five posts without having to go to another page. So, I decided against it and went for the layout as it is now. The size of the text is bigger on the latest post and for posts seen singularly (permanent link), a bit smaller on the previous ones when seen on the home page. The column on the right holds all the site navigation, except for the four main pages, which I left in the masthead.

Country overview: women quotas
“ Obstacles to women's political participation exist throughout the world in prevailing social and economic regimes, as well as in existing political structures. In 2005, the representation of women reached nearly 16 percent globally. Although this total has increased in recent years, the minimal progress globally means that the ideal of parity remains a long way off.”
“ Today women constitute 16 per cent of the members of parliaments around the world. Recently, Rwanda superseded Sweden at the number one in the world in terms of women's parliamentary representation - 48.8% women against Sweden's 45.3%. Rwanda is an example of the new trend to use electoral gender quotas as a fast track to gender balance in politics.”
Italy is the 48th Country, after Afghanistan, Iraq and Pakistan. France is even worse.

Using proper quotation marks:
- On a Mac, use Option+] and Shift+Option+] for the left (open) and right (closed) single quotes. For Windows, use ALT 0145 and ALT 0146 for the left and right single quotes (hold down the ALT key and type the numbers on the numeric keypad)
- On a Mac, use Option+[ and Shift+Option+[ for the left and right double quotes. For Windows, use ALT 0147 and ALT 0148 for the left and right double quotation marks (curly quotes)
- In HTML code the characters as ‘ for and ’ for and “ for and ” for (ampersand, pound sign, number, semi-colon)
- The Unicode numeric entities of ‘ for ‘ and ’ for ’ and “ for “ and ” for ” (ampersand, pound sign, number, semi-colon)
When using the ALT keystrokes in Windows, use the numeric keypad not the row of numbers above the alphabet and be sure Num Lock is turned ON.
