Once, not too long ago in the Enterprise people found themselves working ever so diligently and thought everything was just honky dory thank you very much. Yet they were completely oblivious to the terrible neglect their creative souls were facing. They had forgotten how to imagine, they had stopped practicing the power of insight and ideas were fast becoming stale." ..read more

legs for getting places... (by scottobear, cc)

Web 2.0 tools have made it easier for people to form groups; ranging from temporary flocks of people with a similar interest to close-knit communities, increasingly part of extensive interconnected networks.

Thanks to Web2.0 people can connect and organize, without a manager or a managing structure to lead or frame this organization process. “The power of organizing without organizations” is how Clay Shirky calles it. Others have used the term “non-organizations” or “ultra-lights”. Many Internet mediated groups are non-organizations, in the sense that they do not have a traditional structure or legal entity like a foundation or a association, or a company.

An example is the group of dairy farmers in rural Portugal I am part of, convening around a blog and an email group, and meeting f2f a few times a year for an excursion or study day. There is real value for learning and socializing, there are some shared values, a shared identity. But it comes without the things that used to be part and parcel of more traditional organizations. There is no mailing address, no letterhead paper, no statutes or articles of association, no official “Committee” and no member administration.

When the dairy farmers network wanted to liaise with the traditional Farmers Union in Portugal, they were not accepted unless they would be a “real” association. The “ultra-light” can not be eligible for EU subsidies for training or extension, even though that is what it does.
When hiring a venue to convene, or a leaflet to print, one member has to personally take the financial responsibility up-front. When afterwards members chip in, they can not be given a receipt. The group can not own anything, not hire anybody.

A solution for the non-organizations might be to go the traditional way: formalize the group and rig an organizational structure along traditional lines, depending on the preferences: an association, a company or a charity. But this seems more complex than strictly needed, it would raise transaction costs, and more importantly: what would be lost in the process?
The lightness is a relief, it is felt that the lightness is conducive for learning, for attracting the right people for the right purpose. The agility, the single focus of a group to do its thing, and to stop being a group in case the energy ebbs is unique and refreshing.

This was the conclusion of the case study i did last year:
“Web 2.0 supported communities have the potential to support social organization for development, linking different actors to local development. The organizational models that we avail of at present do not match the new dispersed form of organization. To promote autonomy, sustainability and replicability of communities, further thinking is required.”

John D Smith and I have done some “further thinking”.

We have looked at existing communities, many of them “ultra-lights”, we have reminded each other to look and read with the question in mind:

"How can communities get legs and pockets"?

Legs for getting places, doing the thing it is they want to do;
pockets for being able to pay their way for as long as they want to.

You need legs before you can have pockets, but too large pockets might get in the way for good walking.

We have come across many communities that are -in whatever way- struggling with these questions: some for lack of pockets, others for getting their pockets filled and stopping walking to spend money or get more.

Trying to think of what would be needed to get legs and pockets, one thing might be collective money management tools. A tool to make international online banking "visible" to a larger community, in order for the community leaders to move money in an accountable way. It should be simple, but not too simple; communities probably want to differentiate several "stashes" of money. Read John's blogpost about it here.

Ich denke die weitergegeben Weisheiten und Erfahrungen müssen nicht um bedingt von großem Vorsprung sein zu denen von dem Empfänger. Kleine Informationseinheiten können auch helfen. Gerade, wenn die Informationen immer und überall zur Verfügung stehen. Für mich mache ich hier die Einteilung in Expertenwissen und Masseninformation. Beides denke ich sollte in „The wisdom of crowds“ vorhanden sein. Den damit kann jeder Mensch etwas zum Allgemeinem-Wissen (nicht zu verwechseln mit Allgemeinwissen) beitragen.

Mit dem neuem Verständnis fürs Internet was mit Web2.0 mit gekommen ist, haben sich Teile von Gesellschaften sich verändert. Leider sind nicht Alle dabei. Gerade die Älteren, von deren Weisheit eine Gesellschaft zerren kann, sind unterrepräsentiert im Web2.0. Durch Aktionen wie bloggerpatenschaften.de wird versucht eine Brücke zwischen den Netzwerken aus dem Netz und den Menschen außerhalb des Netzes zu schlagen. Solche Aktionen könnten helfen den "i-Gap" in der Gesellschaft zu überwinden.

Die Möglichkeiten die das Internet bietet müssen besser kommuniziert werden. Viel mehr NPOs (Non-Profit-Organization) müssen sich bilden und sich gegen kommerzielle Angebote durch setzen. Leider liegt es in der Natur der Sache, dass erfolgreiche Web2.0 Angebote von Unternehmen aufgekauft werden. Nichts desto trotz sollte die Partizipation im Internet positiv genutzt werden und nicht nur für Unterhaltung. Gegenüber dem Fernsehen, haben wir im Internet die Möglichkeit das Programm zu machen und sinnvolles mit unserer Zeit im Netzanfangen...natürlich nicht nur!

Jemehr Leute auch ihre Erfahrungen und Wissen, seien diese auch gering, mit ein bringen in Netzwerken erhält die Gesellschaft einen Mehrwert. So muss der nächste Schritt sein zu versuchen den "i-Gap" zu verkleinern oder viele Brücken darüber zu bauen. Jeder kann in seinem Umfeld Begeisterung für Web2.0 Tools und Netzwerke auslösen. Das wird schon helfen. An Schulen und Universitäten muss auch mehr gemacht werden um die "Zukunft" mit Netzsensibilität auszurösten. Gerade Kindern aus Bildungsfernen Familien könnte durch einen sinvollen Umgang mit dem Internet viele Türen geöffnet werden. Dafür müssen aber die Lehrer versuchen die Kinder und Jügendlichen übern den"i-Gap" zubringen.

Ich bin sehr gespannt auf die weitere Entwicklung der Gesellschaft durch die neuen Möglichkeiten die sie hat.

ああ、わすれちゃった！

Avviene però che in certi casi, se per esempio avete fatto un algoritmo in php ma vi accorgete che avreste bisogno dei thread e non avete voglia di mettervi a riscrivere tutto, è proprio necessario un modo per implementarsi i thread.

Allora potremmo usare l'operazione asincrona più naturale che il linguaggio ci fornisce, una richiesta asincrona a una pagina web.

Iniziamo subito con il codice della libreria Thread.php:

[sourcecode language='php']
class Thread{
var $func;
var $arg;
var $thisFileName;
var $fp;
var $host;
var $port;
function Thread($host,$port=""){
$this->host = $host;
if ($port != ""){
$this->port = $port;
}else{
$this->port = 80;
}
$this->thisFileName = $_SERVER["SCRIPT_NAME"];
}
function setFunc($func,$arg=false){
$i=0;
$this->arg = "";
if ($arg){
foreach ($arg as $argument){
$this->arg .= "&a[]=".urlencode($argument);
}
}
$this->func = $func;
}
function setPort($port){
$this->port = $port;
}
function setHost($host){
$this->host = $host;
}
function start(){
$this->fp = fsockopen($this->host,$this->port);
$header = "GET ".$this->thisFileName."?threadrun=1&f=".urlencode($this->func).$this->arg." HTTP/1.1\r\n";
$header .= "Host: ".$this->host."\r\n";
$header .= "Connection: Close\r\n\r\n";
fputs($this->fp,$header);
}
function getreturn(){
$flag=false;
while (!feof($this->fp)) {
$buffer = fgets($this->fp, 4096);
if ($flag){
$output .= $buffer;
}
if (trim($buffer) == ""){
$flag = true;
}
}
return unserialize(trim($output));
}
}
if (isset($_GET['threadrun'])){
$arg_str = "";
$i=0;
if (isset($_GET['a'])){
foreach($_GET['a'] as $argument){
if ($i == 0){
$arg_str .= '"'.urldecode($argument).'"';
}else{
$arg_str .= ",".'"'.urldecode($argument).'"';
}
$i++;
}

}
eval("\$return = ".$_GET['f']."(".$arg_str.");");
echo serialize($return);
exit;
}

?>

[/sourcecode]

Questa libreria è stata scritta originariamente da Alex Lau, io ho fatto alcune modifiche che saranno illustrate dopo.

Ora il codice di esempio per capire come funziona (main.php):

[sourcecode language='php']
include_once("Thread.php");
function get($num)
{
$out = file_get_contents("http://localhost:8080/tesi/crawling/worker.php?num=".urlencode($num));
return time()." ".$out;
}

for ($p=0; $p<6; $p++) {
$thread[$p] = new Thread("localhost",8080);
$thread[$p]->setFunc("get",array($p));
$thread[$p]->start();
}

for ($p=0; $p<6; $p++) {
echo $thread[$p]->getreturn()."
";
}
?>
[/sourcecode]

E di worker.php:

[sourcecode language='php']
sleep(5-$_GET['num']);
echo "thread ".$_GET['num'];
?>
[/sourcecode]

L'ovvio risultato è quello di mostrare come il primo thread creato è anche l'ultimo a ritornare ovvero ha il timestamp più alto.

Nello script di esempio vediamo come si usa la classe Thread, intanto includiamo il file, poi definiamo una funzione che richiama un'altro script passandogli un parametro, questo script contiene ovviamente il codice che vorremmo rendere asicrono.

Andiamo ora a creare il thread, ad impostare il nome della funzione e i suoi parametri, è importante notare che i parametri vanno passati dentro un array sia che siano uno solo sia che siano cento.

Dopo di che lanciamo il thread, successivamente andremo a recuperare l'output della richiesta, notare che questa richiesta è bloccante stavolta, quindi la possiamo utilizzare per monitorare i thread.

Ma come funziona la classe?

Tralasciano l'implementazione il modo è molto semplice, al momento della creazione del thread la classe si salva le informazioni sulla funzione e i suoi argomenti, quando poi si fa partire, la pagina richiama se stessa ma aprendo un socket asincrono, la pagina richiamata in modo asicrono esegue ovviamente le operazioni richieste e il suo output è riferito dall'esterno con un puntatore, in pratica i thread sono creati da apache stesso nel modo più ovvio e naturale che si possa pensare.

Vi faccio notare infine che per motivi di protocollo i valori passati come argomento della funzione sono tutti convertiti in stringhe...

Spero vi sia stato utile.

Enjoy!

On a recent trip to North America I was really impressed by the level of support and passion in Web2.0 but also in Mobile Internet usage, I think you guys use the Internet on your phones a lot more than us Europeans! Which is good for Zinadoo, of course, as USA is our largest and most active market today! When I think back 18 months to when we first launched Zinadoo Site Creation tools, we were engaging with the market and a lot of our time was spent educating users on the benefits of the mobile Internet - things like poor download speeds, weak search, multiple borwsers, high data charges and lack of content....the usual barriers out there! BUT we have seen a dramatic improvement in all of these areas, and now,  in our market and customer engagement we are not spending as much time educating but have now moved onto a different level. How can a business benefit from having a mobile Internet presence, and what can we do to help them promote and market themselves using this medium!

We are doing some interesting work with the Dotmobi Mobile Advisory group as well around mobile advertising and mobile standards compliance, and planning on a big iLoveMobileWeb campaign as well which is very exciting. So many great events coming up over the summer and Nubiq are going to be driving promotion of these events over the Mobile Internet! Should be fun!

Aujourd'hui, j'ai testé ceux que j'ai trouvés et téléchargés hier, parmi les Aggrégateurs de favoris (del.icio.us-like) ou gestionnaires de liens.

J'ai donc été chercher sur le web, qui m'a donné GetBoo, et puis j'ai pensé à chercher directement sur SourceForge, dans la bonne catégorie. Mes critères quand au choix de l'outil étant : open-source, en PHP et pas trop ancien (avec de l'Ajax si possible, et en tout cas, une bonne ergonomie).
J'en ai testé 6.

communitynews

Tout d'abord, communitynews : l'outil est en Python, donc ne m'intéresse pas tant que cela. Exit communitynews.

Pligg

Ensuite vient Pligg, tout d'abord, télécharger la dernière version stable...souci, il est toujours en bêta (la marque de l'appli web2.0) mais prometteur. De plus, pour le télécharger, il faut au préalable se créer un compte sur le forum. Je le fais, car j'ai très envie de le tester.
Il s'agit d'un gestionnaire de news (le nom aurait dû me mettre la puce à l'oreille), genre Digg ou Tomateo, mais il permet bien de mettre des liens et leur contenu (avec en plus la possibilité de voter pour les mises en avant).

Pligg est moderne, bien pensé, avec plein de fonctionnalités (trop?) mais surtout les messages d'erreur ont leur CSS à refaire, car ils arrivent comme un cheveu sur la soupe.

Avant de l'adopter, je teste ceux qui restent.

GetBoo

GetBoo (pour Get Bookmarks) est récent, opensource, en PHP/MySQL. Après téléchargement, je lis le README et l'INSTALL, qui m'apprennent que je dois installer PEAR. Qu'à cela ne tienne, avec mon WampServer, c'est très simple, en deux minutes, c'est fait.
Ensuite, je m'aide de l'installeur web (formulaire) pour configurer ma base de données. L'installeur n'arrive pas à se connecter à ma base. Soit.
Je modifie le fichier de config à la main, afin de spécifier mes préférences, l'outil n'arrive pas à se connecter à ma base de données. Il utilise le package MDB de PEAR.

Aujourd'hui, GetBoo me laisse encore un goût amer en bouche, car je n'arrive pas à obtenir la connexion à la base de données. Si quelqu'un a explication, je suis encore preneuse (pas envie de débooguer toute l'appli), je soupçonne un problème de version, je travaille avec PHP 5/MySQL 5, et j'ai pas spécialement configuré PEAR.

Scuttle

Ensuite, la révélation vint de Scuttle. Scuttle est un outil de bookmarking, qui permet de mettre un utilisateur en favori dans sa Watchlist, qui propose des flux RSS, et des bookmarklets.

Cet outil n'est pas pour les faibles, il n'existe pas, à ma connaissance (ou elle est bien cachée) de doc d'install. Au flanc, j'ai donc commencé par créer la base de données + l'utilisateur attaché à la DB. Ensuite, j'ai modifié/créée le config.inc.php en m'inspirant du fichier par défaut. Il est à noter que l'utilisation de mysqli ne fonctionnait pas, je me suis donc rabattue sur mysql. Enfin, j'ai activé le mod_rewrite d'Apache, afin de profiter de toutes les fonctionnalités.

La page s'affiche bien, hormis un joli message concernant les locales (oui, l'application est traduite en plusieurs langues).
Warning: setlocale() [function.setlocale]: Passing locale category name as string is deprecated. Use the LC_* -constants instead in C:\wamp\www\scuttle\includes\php-gettext\gettext.inc on line 131
Hormis ce gros détail (réglé par un error_reporting(0); dans le fichier de config), l'outil est ce que je cherche. Il est en version Alpha, et en consultant la fiche Framasoft de Scuttle, j'apprends l'existence de forks : ScuttlEDU pour les enseignants et leurs étudiants et surtout SemanticScuttle.

Scuttle n’étant plus développé depuis de nombreux mois, nous avons entrepris de le remettre en route en y ajoutant des possibilités de structuration des tags.

(Eric Dané)

Semantic Scuttle

Avant de crier victoire, j'ai donc testé SemanticScuttle, cette fois-ci on a une documentation, mais forte de ma première installation, j'y suis encore allée au flanc.
SémanticScuttle offre la possibilité d'imbriquer les tags les uns dans les autres, de rendre équivalents deux tags (fr et francais, par exemple, mais pas français, car il y a un petit souci avec les charset pour le moment) et les vignettes des sites web.
Adopté pour moi, il me reste à le faire adopter à mes collègues.

Bookmarks4U

Par acquis de conscience, j'ai été tester Bookmarks4U. Sur la page d'accueil pour le télécharger, il est tout de suite dit :

This Project will NOT be updated ANY MORE.

ce qui refroidit un peu. Mais c'est le premier de ce genre de produit, leur ancêtre un peu, je me dois de le tester. Je l'installe tout bien et au moment d'aller sur la page, parse error !
En lorgnant dans le code, je vois une variable nommée $row[public], or en PHP5 public est devenu un mot-clef...donc cette notation, à bannir pour vos tableaux, pose un problème de portabilité. Utilisez donc des quotes autour des index de vos tableaux, svp. (cf. Why is $foo[bar] wrong?).

Spannende Themen haben uns hier umgetrieben, bei denen immer wieder eine wichtige Frage diskutiert wurde, die meiner Meinung nach die Entscheider im Internet in den nächsten Monaten und Jahren maßgebliche beschäftigen wird: how to monetize social networks? Eine schlüssige Lösung konnte bei vielen Ansätzen noch nicht präsentiert werden.

Diese Garage sollte der Auftakt zu mehr Events zum Thema Facebook in Europa, und speziell in Deutschland bilden. Man kann gespannt sein, eine Fortsetzung wird morgen auf der Next08 erfolgen.

The Library of Congress' photos - Flickr
http://www.flickr.com/photos/library_of_congress/

It is not directory related to Japanese Studies, but there are a lot of interesting photos. For instance, there are more than 300 photos with a tag "world war II" and about 460 photos with a tag "1940s."

Nach eigenen Angaben ist "Pipl designed to retrieve information from the deep web, our robots are set to interact with searchable databases and extract facts, contact details and other relevant information from personal profiles, member directories, scientific publications, court records and numerous other deep-web sources."

Die Ergebnisse sind absolut beeindruckend. Ganz 'en passent' liefern die Betreiber von pipl eine ganze Reihe von statistischem Material (vom Alterstrend bis zur gegrafischen Verteilung) zu den wichtigsten social networking sites (von Facebook bis Frienster).

Parmi les tendances Web du futur-présent à surveiller selon lui:

1. la widgetisation du web
2. la portabilité des donnees
3. le social gaming
4. et encore plus d'expérimentations (les consommateurs s'expriment sur l'idéation produit- suggestions)
5. Le contenu est une commité (le contenu étant gratuit et non-exclusif). Ainsi, il faudra trouver autre chose que du contenu pour attirer et capturer les gens.

Quote from the article: 'We've noticed that many people don't use some tools that would make their lives online much more effective and efficient. Here's our list of some tools we'd suggest are essential. Several of these tools will deliver huge value to your workday and take less than 10 minutes to get set up.'

Based on this article, I started using some of them - these are indeed essential tools!

1. Multi-service IM: makes IM more easy!

2. Cross Platform Screensharing Tool: not used yet; is similar to Microsoft NetMeeting used in the corporate environment

3. A Custom Search Engine: this is really useful; you can now search only on my blog using google

4. Startpage: I use Netvibes, this is really great!

5. Blog With Your Name and Contact Info: will put my gmail address on the blog

Do you know other essential tools?

The first, in following with the end-of-year theme, is the commencement speech by Barbara Kingsolver.  I'm a big fan of hers.  I really enjoy the humor she injects in to her writing (and this speech) as well as the content she writes about.  If you haven't read Animal, Vegetable, Miracle yet, I highly recommend it.  Here's a quote (from the more serious side of her speech):

In the last 30 years our material wealth has increased in this country, but our self-described happiness has steadily declined. Elsewhere, the people who consider themselves very happy are not in the very poorest nations, as you might guess, nor in the very richest. The winners are Mexico, Ireland, Puerto Rico, the kinds of places we identify with extended family, noisy villages, a lot of dancing. The happiest people are the ones with the most community.

The second piece is a video called "Learning to Change" by the Digital Arts group at the Pearson Foundation for CoSN.  It's another video that you should show to  teachers and stakeholders in your schools.  Take a look:
