Tuesday, January 26, 2010 - Pinning Down Accidents Caused by Cell Phones
Category: Public Policy
The National Safety Council (NSC)
estimates that 25% of all crashes are caused by cell phones.
The National Highway Traffic
Safety Administration (NHTSA) estimates that driver
distraction from all sources (including cell phones) contributes to
19 percent of all crashes (2008). Even then, this is not
necessarily the cause of the crash.
Both cannot be true, someone here is wrong. The NSC report is
merely a statistical extrapolation of what might have happened,
heavily based on averages. More real world data to corroborate
their numbers is needed. The NHTSA has the opposite problem. Their
numbers are based on real world reports. These suffer from
reporting errors, often because those involved in a crash might not
report being distracted while driving.
Wednesday, January 20, 2010 - Almost Flooded
Category: Photo Gallery
My apartment nearly flooded once the downpour started. Its a good
thing that I was able to improvise and put my phone books to use
for once and fill in the cracks with dirt and mulch from nearby
(and the rain slowed). Minor flooding isn't unusual for this
apartment since it is low lying, but it usually doesn't go much
past the stairs or porch. Today was different. The combination of
over an hour of heavy downpour and a new landscaping job left my
apartment especially vulnerable, turning my staircase into a river.
I called the office, they said they would send maintenance but I
lost hope of that since its already past 5 PM here. The video and
first few photos are from before my handywork, the remainder are of
the aftermath. San Diego, CA. January 18, 2010.

Monday, December 7, 2009 - IPv6 Quirks
Category: Computing Technology
After playing with IPv6 extensively over the weekend, I discovered
a number of oddities about the protocol.
First, autoconfiguration only works with /64 subnets. Anything more
or less, even if the router advertises the prefix, clients will not
add the prefix to its own interface. This seems like it can
problematic as users cannot easily break down these prefixes into
smaller subnets. This could be a key area for using DHCPv6 as a
replacement.
Second, autoconfiguration will not work if the computer is
configured as a router for IP forwarding. This means that
additional work for defining routes needs to be done even if you
only plan on using the default gateway on a network. This can
either be in the form of static routes or a full blown routing
protocol.
Third, 2002::/16 (IPv4 transition addresses) doesn't count as a
real IPv6 address when source address selection occurs. Instead it
is considered a separate scope, similar to an IPv4 address. This
means when websites have both a 2001::/16 IPv6 address and a IPv4
address, the IPv4 address is used by default. If the website has a
2002::/16 IPv6 address and a IPv4 address the 2002::/16 IPv6
address is used to connect. This seems very odd and inconsistent
and can lead to confusion.

Tuesday, October 27, 2009 - Appupdater Research Publication
The paper, "An Implementation of the Linux Software Repository
Model for other Operating Systems" was included in the Second ACM
Workshop on
Hot Topics in Software Upgrades (HotSWUp'09). The paper and
presentation can be downloaded from the workshop website at:

Wednesday, October 14, 2009 - Appupdater 1.3 Released
IMPORTANT: You must either upgrade to 1.3 or newer OR download the
2010 key (https://www.nabber.org/Nabber.org.2010.pub.asc)
to your "keys" directory OR do a manual update (GUI: Download Apps
List, Console: --update --force). Failure to do ONE of these by
December 31, 2009 will cause you to stop receiving updates.
