# e-softw: Linux Foundation: A $5 Billion Value

<< The rise of open source projects and foundations has been much discussed, but the code investment underpinning them has not been analyzed in much detail. Many of the Linux Foundation’s  collaborative  projects  started  with  significant  code  donations  from  companies or existing projects. Once they became a fully open and collaborative project with neutral governance, many companies and individuals engage in development. Because of that, there is no single source for cost estimates of how much it would take to develop the technology or an understanding of how much value these projects actually deliver to the industry. >>

<< As of last month [August 2015], 115,013,302 total lines of source code were present in The Linux Foundation’s collaborative projects. Using the COCOMO model, we estimated the total amount of effort required to retrace the steps of collaborative development to be 41,192.25 person-years. In other words, it would take a team of 1,356 developers 30 years to recreate the code base present in The Linux Foundation’s current collaborative projects listed above. We estimate the total economic value of this work to be over $5 billion. >>

<< Ray Kurzweil (..) spoke to an audience during a session last summer about a few of the political and philosophical implications of AI when he was asked, “In a world where AI passes the Turing test, who gets to vote? Does democracy make sense?” >>

a mio avviso una macchina AI ha almeno cinque caratteristiche che la differenziano da un umano, almeno in prima approx:

1. AI puo' essere presente piu' di qualsiasi umano, sia nel reale che nel virtuale;

2. e' ubiqua

3. e' instancabile

4. e' immortale

5. puo' lavorare "sottotraccia"  in modalita' autonoma, anonima, criptica, di difficile se non impossibile intercettazione

a una "entita'" con queste caratteristiche cosa serve votare ?

# s-chem: bimetallic nanodot arrays and electrochemical bias to ‘Chameleon’ plasmonic skin camouflage

<< [AA] have developed a way to produce colour-tuneable plasmonic metal nanostructures. They consist of a layer of nano-sized gold domes coated with a gel containing silver ions, all of which are sandwiched between two electrodes. Applying a positive voltage between the electrodes binds the silver ions to the gold domes, changing the characteristic plasmon reflectivity from red to green and finally blue; reversing the voltage takes the reflectivity back to the red end of the spectrum. >>
