Understanding social media in China

by gianluca quaglia

*Understanding social media in China* The world's largest social-media market is vastly different from its counterpart in the West. Yet the ingredients of a winning strategy are familiar. APRIL 2012 . Cindy Chiu, Chris Ip, and Ari Silverman No Facebook. No Twitter. No YouTube. Listing the companies that don't have access to China's exploding social-media space underscores just how different it is from those of many Western markets. Understanding that space is vitally important for anyone trying to engage Chinese consumers: social media is a larger phenomenon in the world'sa second-biggest economy than it is in other countries, including the United States. And it's not indecipherable. Chinese consumers follow the same decision-making journey as their peers in other countries, and the basic rules for engaging with them effectively are reassuringly familiar. Surveying the scene In addition to having the world's biggest Internet user base---513 million people, more than double the 245 million users in the United States1---China also has the world's most active environment for social media. More than 300 million people use it, from blogs to social-networking sites to microblogs and other online communities.2 That's roughly equivalent to the combined population of France, Germany, Italy, Spain, and the United Kingdom. In addition, China's online users spend more than 40 percent of their time online on social media, a figure that continues to rise rapidly. continua qui https://www.mckinseyquarterly.com/Marketing/Digital_Marketing/Understanding… Qgl

Neubot 0.4.11 released

by Simone Basso

Version 0.4.11 is the latest generally-available stable release of Neubot, distributed for Ubuntu >= 10.04, MacOSX >= 10.6, Windows >= XP SP3 and FreeBSD, as well as in source format. Here's what changed in less than 140 characters: win32 auto updates prototype, bug fix for a database bug that corrupted pre-0.4.6 results, new event scheduler, cleanups, docs and fixes. Install, upgrade instructions at http://www.neubot.org/download, read on for more details. This release contains 111 commits. The diffstat says: 86 changed files with 4,102 additions and 278 deletions. Here is the list of what changed and why: - win32: auto updates prototype (still experimental) https://github.com/neubot/neubot/commit/781ae533 This commit includes support for automatic updates in the Windows environment. This piece of work is still marked "experimental", mainly because the code for signing and verifying the update tarball is not yet implemented. My opinion is that one can also trust and install code that is not signed, but I know that most people are not of the same advice. Hence, by default this feature is disabled, and I won't make it the default until there is sign/verify code. So, if you want to exploit it, make sure that you set ``win32_updater`` to ``1``, using the settings page (http://127.0.0.1:9774/settings.html) - database: fix pre-0.4.6 results corruption bug https://github.com/neubot/neubot/commit/33b479a8 In Neubot 0.4.6 I made a stupid programming mistake and introduced a bug in the database code. This bug caused pre-0.4.6 results to be somewhat corrupted. In particular, for each result row, values were permuted. Luckily it seems that the permutation depends on the version of Python and on the system architecture. This means that I'm confident that it's possible to undo this problem in most cases. The fix works like this. First, runs both the broken and the fixed code to compute the buggy permutation. Then, it scans the whole database of results and searches for suspicious lines, i.e. lines where the IP address does not look like an IP address, or the operating system name is not a string, etc. Whenever a suspicious line is found, the code tries to undo the buggy permutation. If the result after the undo makes sense, the code overwrites the suspicious line. Otherwise it is left untouched. Note that it takes some time to search the whole database and eventually fix suspicious lines. It should not be a tremendous boot-time issue: on UNIX Neubot forks before opening the database, while on MacOSX and Windows it is started as a background process. The worst thing that can happen is that, just after boot, Neubot uses a lot of CPU for quite some time. I have tested this bugfix passing Neubot big databases collected on the server side during the lifetime of the project. I have tried to be careful to guarantee that the algorithm to fix this bug consumes a constant amount of memory and does not fail spectacularly. I have, of course, also checked that the bugfix code does not screw new data. And I have also been quite conservative: the patch was finalized more than one month ago, but I decided not to include it in 0.4.10 to perform further testing. However if you notice any issue with it, please let me know as soon as possible. - www: add workaround for IE8 plot issues https://github.com/neubot/neubot/commit/fe5f9565 As reported by Joachim Kross (thanks!), speed and latency plots are empty with Internet Explorer 8, unless one enables the compatibility view mode. This release ships with a workaround, which loads the proper set of javascripts with Internet Explorer 8. With this fix in tree, plots are now shown correctly, both in compatibility and in normal mode. Thanks to Alessio Palmero Aprosio, who did most of the work needed to workaround this problem. - new event scheduler based on stdlib sched https://github.com/neubot/neubot/commit/2f70d911 Comparative tests showed that Python standard library scheduler module (``sched``) was more efficient than Neubot native one. As a consequence, quite some time ago I started working on a diff to replace Neubot scheduler with standard library one. During this release cycle I finally managed to finalize this work, and, since it was stable, I decided to include it in this relase. - More code rationalizations, cleanups, documentation improvements, and bug fixes.

sentenza ECJ su data retention e PI

by avv. Monica A. Senor

La Corte europea di Giustizia, con sentenza 19 aprile 2012, ha sancito il seguente principio: La direttiva 2006/24/CE del Parlamento europeo e del Consiglio, del 15 marzo 2006, riguardante la conservazione di dati generati o trattati nellambito della fornitura di servizi di comunicazione elettronica accessibili al pubblico o di reti pubbliche di comunicazione e che modifica la direttiva 2002/58/CE, devessere interpretata nel senso che non osta allapplicazione di una normativa nazionale, istituita sulla base dellarticolo 8 della direttiva 2004/48/CE del Parlamento europeo e del Consiglio, del 29 aprile 2004, sul rispetto dei diritti di proprietà intellettuale, la quale, ai fini dellidentificazione di un abbonato a Internet o di un utente Internet, consenta di ingiungere ad un operatore Internet di comunicare al titolare di un diritto di autore ovvero al suo avente causa lidentità dellabbonato al quale sia stato attribuito un indirizzo IP (protocollo Internet) che sia servito ai fini della violazione di tale diritto, atteso che tale normativa non ricade nella sfera di applicazione ratione materiae della direttiva 2006/24. Questo il link alla decisione: http://curia.europa.eu/juris/document/document.jsf?text= <http://curia.europa.eu/juris/document/document.jsf?text=&docid=121743&pageI ndex=0&doclang=IT&mode=req&dir=&occ=first&part=1&cid=1183443> &docid=121743&pageIndex=0&doclang=IT&mode=req&dir=&occ=first&part=1&cid=1183 443 Il principio così come espresso potrebbe lasciare attoniti, ma la motivazione pare più convincente Un caro saluto e buon 25 aprile a tutti.
