China Blocks Chinese Word for 'Egypt'

It's interesting to see how the fragmentation of the Net continues. Imagine
not being able to search for current events in Mexico, Europe, or elsewhere.

China's microblogs have blocked searches for the word "Egypt," a sign that
the Chinese government is trying to limit public knowledge of the political
unrest occurring in the Middle East. The blocking appeared to begin over the
weekend on the Chinese Twitter-like services operated by Sina, Tencent and
Sohu. Queries using the Chinese word for "Egypt" brought no results. "In
accordance with the relevant laws, regulations and policies, the search
result did not display," said the response on the Sina microblogging
site. The English word for "Egypt," however, is still searchable across the
sites.


Egypt: Risk for a Country

Source: Patrick Thibodeau, Microsoft shifts some work out of Egypt;
It is among some 120 companies located in Cairo's Smart Village IT office park
*IT Business*, 31 Jan 2011
http://www.itbusiness.ca/it/client/en/cdn/News.asp?id=61100

Selected text:

Egypt has been aggressively attracting tech companies to its wired office
parks to help create jobs for its young, educated and often English-speaking
workforce. But by cutting off Internet access last week in the wake of civil
unrest, Egypt's government demonstrated just how quickly it can unwind its
hi-tech goals.

Egypt's move to block Internet access prompted Microsoft to respond.  Asked
about the situation in Egypt, Microsoft said in a written response to a
query that it "is constantly assessing the impact of the unrest and Internet
connection issues on our properties and services. What limited service the
company as a whole provides to and through the region, mainly call-center
service, has been largely distributed to other locations."

Egypt's decision to cut Internet access was apparently intended to disrupt
the ability of protestors to use social networks to organize.  But hi-tech
companies have similar flip-the-switch abilities and can shift services in
response to a natural or manmade disaster. It is almost certain that tech
companies in Egypt will respond to the current uncertainty much the same way
Microsoft did—if they haven't already.

The reason that it was so easy to disconnect a country from the rest of
Internet is that today's Internet protocols are very much aligned with
authority. You get your IP addresses from authorities (providers) and depend
on a single backbone that requires we trust all providers.

This is a point I make in http://rmf.vc/Demystify.risks.

It is not sufficient to lament Egypt's actions—we need to move beyond
today's prototype architecture to one that honors the end-to-end principle
by removing the dependency on a centralized authority by defining
connectivity in terms of stable relationships apart from any network. We can
then use whatever facilities are available to exchange bits. The presumed
safety of today's DNS is an illusion that has consequences such as assuring
the Net will unravel as our temporary hold on our own names expires.

Skype gives a hint of what is possible but it relies on a central directory.
The first step is removing the prime dependency—the need to pay mere to
exchange bits over a common infrastructure. We can then evolve to new
protocols that aren't constrained to providers' pipes.

  "In the longer term, we are sure that the world will learn a lesson from
  this very unfortunate example, and come to understand that cutting off a
  nation's access to the Internet only serves to fuel dissent and does not
  address the underlying causes of dissatisfaction."

It appears that the "lesson learning" statement therein is beamed at
governments. Unfortunately, there seems to be ample and convincing evidence
that "lesson learning" (at least of the benevolent variety) is not a skill
generally within the capabilities of any government. However, it is true
that this is a "learning moment", and the lesson that I have received is
that any of us who value Internet freedom had better have a "Plan B" that is
independent of government, whether that plan involves a darknet, archived
DNS records, or some as yet unformulated solution. Jacob Appelbaum and some
associates have evidently provided some dial-up ISP connectivity to
Egyptians, but while that is an admirable improvisation, it is also woefully
inadequate as a functional solution. On the other hand, I think that I will
refrain from tossing my very last US Robotics 56k modem just yet...


Non-snailproofed traffic light proves fatal

One night last August in Tamworth (near Birmingham), England, two cars
driven by teenagers collided head-on on a one-lane bridge, and one of them
was killed.  It has now been revealed that this happened because the traffic
lights governing the one-lane bridge were short-circuited by a snail or slug
crawling over the circuit board.  The surviving driver said he saw the other
car but did not realize what was happening in time.

Most reports do not mention the state of the lights, so I suppose they were
dark rather than showing green both ways.  The failure had been
automatically reported at a monitoring station, but the collision happened
only 20 minutes later.

Public service announcement on Undigestifying

Jonathan Kamens <jik@kamens.us>
Sun, 16 Jan 2011 22:13:12 -0500

For those of you who use Thunderbird or Postbox to read your email, I've
just released a new add-on called "Undigestify" at
https://addons.mozilla.org/en-US/thunderbird/addon/undigestify/. If you
install this add-on, then you can right-click on a Risks Digest and
select "Undigestify", and the digest will be split into separate
messages which you can then read and respond to individually.

(For those of you who are old and nerdy enough to have used Emacs RMAIL
to read your mail, this is equivalent to M-x undigestify.)

Please feel free to forward this to any other digests whose readers might
find it useful. RISKS is the only RFC 1153 digest I still read, so I don't
know who else is out there who might benefit from it.

Please also feel free to contact me with comments, questions or bug reports.

  [Jonathan, Many thanks!  I occasionally still get a complaint about the
  the RISKS *digest* format, so I am happy to know of your undigestifier. PGN]


BBDB ran off with my Spacebar press

There I was paging down with the spacebar, when I noticed something
stuck. Way down in the emacs minibuffer the little snot "BBDB" program it
turned out has been asking me a question, ever so happy to take the spacebar
I had typed (intended to scroll down) as a "y". `Add address
"bla@example.org" to "goo@nurd.example.com"? (y or n) y'

Sort of like when you slip a piece of paper under a voter's pen before he
notices it's too late, then run off in glee.


Re: Cyberwar countermeasures a waste of money, says report (R 26 31)

Here in the DC area, one of the local online-learning institutions has long
run an alarmist "cyber war" radio ad promoting their online certificate
program in cybersecurity.  The lead-in is a woman talking to someone on the
phone about money suddenly disappearing from lots of bank accounts.  Later
in the ad we return to this conversation in time to hear "Now they're saying
it's the cell networks too!  ...Hello?  Hello?"

I wonder if they will move to a more moderate presentation now.  (I'm
not betting on it.)—Joe

This was a long tale, in installments, about the need for personal backups
of all data you want to keep: So far, so good.

Paul then decides to "upgrade" from a DVD burner to a BD burner, when the
only good backup these days is to have all your data on multiple independent
disks, all of which are in regular use:

My personal backup strategy for the laptop which carries everything I work
on is to have at least two external USB drives, neither of which are
normally plugged in.

The laptop has a 640 GB 2.5" drive, so my main portable backup is a 750 GB
2.5" drive which runs on USB power. (I also carry my previous internal
drive, a 500 GB model, as a backup.)

A tiny batch file is sufficient to copy all updated files from a set of
working directories onto the USB drive, then I disconnect it again.

When at home I also have a larger 3.5" USB drive, this one requires external
power as well as the USB cable.

If I should suffer a total disk crash while on a longer trip, I can open the
laptop, replace the disk with the previous main drive and be back in
operation in an hour or two, including the time to install all the security
updates and copy back recently updated files.

The total cost of this backup strategy is around $100 every year or two when
I buy one of the latest big laptop drives.

The key idea here is that only media and disks that you regularly
use/monitor/upgrade can be depended upon to last!

Terje

PS. I also use my Dreamhost-based personal server and an RSYNC account for
real offsite backup of some really critical (encrypted) files. :-)

Paul Robinson <paul@paul-robinson.us> writes:

For small backups, Robinson's suggestion is probably fine. As you start to
fill up your new 2TB drive, the backup cost will rise substantially; worse,
the time to backup will increase to the point at which you may become
discouraged to do backups.

As you noted, HDDs have gotten very, very inexpensive, and you can get
external drive docks at under $50, so this is my preferred mechanism now for
backups.

Risk: staying in a paradigm after technology has passed it by.
