Good to hear him speaking up about corporate abuse of power over the
What I find really w-e-i-r-d about the whole "cloud" phenomenon is that
it occurs as the cost of terabyte storage has become almost trivial. I
can understand people using cloud services as backup systems and as
means of synchronizing and transferring data across multiple devices.
But using it _instead of_ one's own storage devices is just phenomenally
stupid: caving in to a rent-seeking business model, and creating
vulnerabilities too obvious to even waste electrons here to list.
He also points to the rapid tightening of corporate control over the OS,
by the usual suspects. "Giving them more control of our data, and
therefore of _us_."
Control is a zero-sum game where the score runs from 0 to 100%. The
more control _you_ have, the less control _they_ have. The more control
_they_ have, the less control _you_ have. Zero sum. Fixed quantity
that does not grow over time. For any given item, you control it or
_they_ control it, and "shared" control really means _they_ control it.

surveillance gives governments access to data they couldn't get
otherwise. You can think of it as a public/private surveillance
Exactly. Mutual back-scratching. If you don't approve of government
surveillance, don't make it even easier for them by using Google,
Facebook, and Twitter. Make it harder for them by using AdBlock,

Note that the accuracy of voiceprint identification has been
hugely exaggerated. That number has been touted primarily by
prosecutors, and by voiceprint identification "experts" who make a
nice buck from offering their services. But just as has been the
case with lie detectors, these claims have not stood up to
rigorous scientific validation.
Of course, that doesn't mean that they won't be used against you
in a court of law, regardless of your guilt or innocence! And some
have been falsely convicted to decades in jail or worse on the
basis of this kind of "evidence".
Forensic speaker recognition has many limitations and is currently
inadmissible in federal court as expert testimony. Bonastre et al
(2003) summarize these limitations quite well:
"The term /voiceprint/ gives the false impression that voice
has characteristics that are as unique and reliable as
fingerprints... this is absolutely not the case."
The thing about voices is that they are susceptible to a myriad of
external factors such as psychological/emotional state, age,
health, weather... the list goes on. From an application
standpoint, the most prominent of these factors is intentional
vocal disguise. There are a number of things people can
intentionally do to their voices to drastically reduce the ability
of machine or human expert to identify their voice correctly (you
would be amazed at how difficult it is - nearly impossible - to
identify a whispered voice). Under these conditions,
identification accuracy falls to 40 - 52 percent (Thompson 1987),
36 percent (Andruski 2007), 26 percent (Clifford 1980).
