Bell o Boole?

Le società telefoniche stanno per fallire spettacolarmente a livello mondiale, ed alcune hanno già cominciato. Le altre, fiutato il pericolo, si attaccano al santo protettore richiedendo a) una grossa fetta dei nostri soldi e b) nuove leggi che stronchino la concorrenza.

Le menti pensanti della blogosfera da tempo cercano di attirare la nostra attenzione sul fatto che la posta in gioco è enorme, e le conseguenze sul nostro futuro pesantissime. David Isemberg ha recentementè scritto una lettera al direttore della FCC americana in cui invita a lasciar fallire quelle aziende che si basano su un mdello obsoleto, e favorire la crescita del nuovo.

Shirky nella sua newsletter commenta magistralmente l’attuale situazione come segue:

“The current crisis in the telecom industry is the clash of two 18th century ideas – Alexander Graham Bell’s telephone, and George Boole’s two-state system of logic, which became the foundation of digital networks. For most of the last century, if you’d asked anyone which of those two men’s inventions was most important, the answer would have been Bell by a mile. The phone was on the short list of absolutely critical inventions, while Boolean logic was on a much longer list of interesting mathematical curiosities.

George Boole


Over the last 3 decades, however, that situation has been reversed. Like the telegraph before it, the telephone turns out to have been only a short-term patch, and digital logic is the invention of long-term importance for telecommunications.

Almost every choice critical to the operation of the telephone network turns out to have been a bad choice, and a hundred and fifty years after Boole’s work, the digital alternatives turn out to be the better ones. Telephone networks assume that conversations must be given an entire circuit for the duration of the call. Digital networks can break up data into packets and share infrastructure much more efficiently. Telephone networks are optimized for voice at every part of the system. Digital networks treat voice as one of many possible data applications. Telephone networks are optimized for synchronous and one-to-one communications. Digital networks can support those patterns of communication, but also asynchronous, one-to-many and many-to-many patterns as well.

In addition to being philosophically superior, voice as a digital application is now good enough for the early adopters of Voice over IP to disconnect from telephone networks, relegating voice to just another item of a large and growing list of broadband applications.

This is the transition from sail to steam, in other words, and the owners of the sailboat cartel aren’t very happy. The incumbent telecoms are fighting against the change harder than the beneficiaries of digital networks are fighting for it, because for the telecoms, their existence is at stake. Their current strategy is simple: they want the FCC to outlaw competition, or, if that proves to be impossible, then they want to use the lever of Government regulation to slow and weaken their competitors in order to be able to milk their outdated network architectures and fee structures for as long as possible.

Noto ancora come i mezzi di informazione di massa ignorino totalmente questi argomenti non adatti al grosso pubblico.

La gaffe del giorno di Microsoft

Questa è davvero singolare. Mi ero iscritto alla mailing list Microsoft su Palladium, per tenermi aggiornato sull’argomento. Oggi mi arriva il terzo comunicato, che tra l’altro dice:

New format

Beginning today, we are sending our newsletter in text-only format. In previous mailings, on September 18 and October 3, you likely received an HTML version of this newsletter (unless your email is configured to receive plain text only).

HTML format is standard for many email newsletters as it allows for a more visually pleasing format and a means of allowing the sender to track the reach of the newsletter. Measuring this reach involves placing a tag embedded in the HTML that is not readily visible to the recipient (see technical details below), but tells the sender if and when the newsletter is opened.

As a matter of policy, Microsoft is committed to notifying individuals about all collection of personally-identifiable information, and in this case, no PII was collected. However, since HTML mail tags have been abused by many in the past, we have decided to move to a text-only newsletter format for all our future communications, and apologize for any misunderstanding this instance might have caused.

We do want to assure you that no personally identifiable information was ever sent to or collected by Microsoft, and no unique identifier was sent to Microsoft or our email newsletter agency. In the end, we believe this change will allow you to still get full use out of our correspondence while also knowing that Microsoft is committed to protecting your privacy.

Technical details of the HTML newsletter behavior

  • Each HTML version of the e-mail contained one HTML tag –

    “img src=3D”http://pens.tm500.com/track.php/74D0265C6D/icon.gif” height=3D1=width=3D1″
  • The image tag was from the same domain as the domain from which the e-mail message originated (e.g., pens.tm500.com).
  • The tag URL contained a serial number (e.g., 74D0265C6D) which was tied to the specific e-mailing.
  • On the network, one HTTP GET could be seen going to pens.tm500.com when the message was viewed. The GET request contained only standard HTTP GET information (e.g., browser type, version, language, OS).
  • One HTTP response was sent back containing the GIF (a blank, transparent icon).
  • The number of times that the GIF was requested was used in reporting (the IP address was not used in reporting).
  • On the management server, we could view how many requests had been made for the GIF associated with the e-mail. No other information was provided. (This is the same way that common web page counters work.)
  • The tag was visible at the end of the e-mail if you used a text mail client or you viewed the original message source.
  • Opening the message multiple times would not generate multiple requests if the mail client caches HTTP objects.
  • Many spammers will often include your e-mail address, or a unique identifier, to track specifically what e-mail addresses are valid. Thus, opening a piece of spam in an HTML capable e-mail client will ensure you get more spam from them. This was not the case with this tracking tag.
  • There is an option in Outlook Express to “Read all messages in plain text.” If the user had this option checked they would not have requested the tag.

Davvero stupefacente! Campioni del mondo nello spararsi nel piede! Non passa settimana che non vengano beccati con le mani nella marmellata.

L’etica del weblog

L’avrai sicuramente già letto, ma voglio copiare quel che Doc ha appena detto sull’etica dei weblog:

What we have going for us here in the blog world is a different kind of familiarity with the people we read. We also have the opportunity to fact-check the crap out each other, and watch Google put it all on its public record.

There is also a very different sense of the first person plural, of we. It’s a social place, this blogging world. More like a public market, full of gossip and noise and the sounds of vendors selling and customers arguing.

And, like an old fashioned public market, nobody owns or dominates the conversation. Not even Microsoft. Maybe not even Google.

E per un esempio di “opportunity to fact-check the crap out each other“, vedi l’Arianna senza filo qui sotto.
