Such a move would do away with radar and other speed trap tools.

All that would be needed is a box that gathers this information and
issues citations.

A patrol car need only get close. Static devices catch you in passing.
Static devices can log you in passing. Any traffic light would have the
location and position to also be a speed trap.

Contra flow traffic would gather an astounding number of vehicle information
bursts.

I wonder if traffic avoidance and serious injury line up well.
I would expect most serious injury events involve vehicles
crossing the median and encountering oncoming traffic. If the
Russian traffic videos I see the serious wrecks happen in
seconds and involve cross traffic or oncoming traffic.

Next there would be a mandate for video recording .... That
may be a good thing. If autos had continuous recording cameras
a lot of traffic stop shenanigans might go away but most police
departments would dislike this. The best camera configurations
could be those that have a wide view and would be witness to
lots more. A simple click of the auto remote would silently start the
cameras as the bystander moved well clear of the action.

Cell or WiFi links could move data to a difficult or impossible to corrupt
cloud location as well as keep a local copy.

I sort of see some value in this but the notion of GPS latency and V2V
data being current enough for avoidance and active safety seems like an
astounding technical reach today. This is revenue generating, grudge and tracking
not safety.

Where are bicycles in all this... Clearly in the modern green future bicycles, scooters,
and motor bikes need to be factored in all of this. Skateboards too.

N.B. We do not mandate transponders for all aircraft....

The kit, as described, is a barely adequate 36 hour kit, for four people.

OK for 36 hours in america all you really need is water.

Most individuals can fast for 36 hours.

In addition a can of tuna or a can of soup needs nothing beyond
an opener and a fork or spoon to become food. If you are hungry it is just fine. If it is
not fine you are not hungry...

It gets different if you are hiking or digging through rubble.

Shelter could be high on the list for many...
A blue tarp is inexpensive.

Trash and sanitation need attention...
The superdome and katrina would have been less evil if
there were buckets on ropes and ways to just flush the crud over the
side. Sadly too many had no clue about sanitation and EXPECTED
others to clean up. This responsibility issue and an exclusion zone where
only trained first responders can play is also a disaster in and of itself.

Reach and scope of the disaster can be overlooked.

A katrina wrecks an astounding area in some cases permanently.
Politics imposes limits on rebuilding which gets manipulated
by do-gooders.

A tornado totally wrecks a narrow band that can often
be accessed by first responders in half a mile left/ right of the

A quake is a regional disaster... small medium large...
One lady in Napa was interviewed -- she had wine but ALL the wine

The area of the Napa quake is modest and lightly populated ....

Economic resources of the area come to play.
Does the population live paycheck to paycheck (Katrina)
or is the population flush with a credit card that would
let them move to another state and a work from home

So a blue tarp, water and some cans of tuna and

Not sure where you live, but writable blu ray was available in 2002 initially. DVD in 1997, CD in 1988. We're a little past 5 years. Thats 12 for BD, 17 for DVD, and 26 for CD. There is a wealth of data on storage life on all of them if you know where to look.

Yes,
yet there was a big deal not too long ago where DVD media began to come apart
after about five years. The rumor was that it was a manufacturing FUBAR that lasted
a couple years and impacted a lot of big name players.

I picked five years to comment because apparently the life of media has two statistical humps.
The five year one points to short term risks unknown at day one and the 12 and 17 year data gives
hope that the 40 to 100 year storage life expectation is possible. Bursts of defective media discovered
a couple years after mfg remind folk that inexpensive could be foolish.

Home users had a spate of problems in 2003 or so... if my Google foo is telling.

If they only keep one copy, how do they detect and recover from bitrot?

Or is the stuff already not really important to keep more than one copy around

Data replication is an honest question. What if a copy was kept on spinning disks
and the Blue-Ray media was backing store for spinning media.

A RAID design for the future need not have equal access times for ECC, voting
and redundancy. It only needs to be reliable and the net sum of the parts
inexpensive. Data rates on and off a single Blu-Ray are consistent with very long
distance optical fibre data rates.

If I allow myself to think of this as heterogeneous RAID hardware design it makes sense.
If I allow myself to think of this as an isolated magic solution it seems fragile.

You could have a robot unplug/plug HDs, but once you're accepting the latency of disk changes and spin-up, I imagine Blu-Ray disks would be much, much cheaper than a similar capacity of HDs.

Yes except the connectors are not rated for many disconnects and reconnects.

Hard drive media needs to spin up often. If the drive is not spun then there are
risks of the media and heads having problems. The complexity of the electronics
and component life expectancy on the drives may be less than Blu-Ray media.
There are just too many moving (active) parts in the drive to believe that media with
no moving parts has an equal MTBF value.

With deep pockets and money in the bank... this is worth a hard look.

This estimate also ignores the cost of a robotic system, powering that system, and maintanence and doesn't factor in costs for redundancy (they need two robotic systems, not one.) The whole thing is phenomenally stupid. As someone already pointed out before I got here to say the same, if you want to take data offline simply literally take it offline. Power down the friggin hard drive array completely. Power it back up when needed.

Bingo... but given the mass of data Facebook has set themselves up to store they would
do well to try a multitude of things.

And redundancy of two at this scale is not going to be sufficient.
The media will need to be organized as a RAID larger and wider
than anything folk are used to thinking about.

A read error on one disc will need to be validated by a very big ECC code
on the media and also on redundant media local and far away. Two copies
gives little voting confidence as to which is incorrect so dust off your old
HP-41 calculator and stat pack or perhaps SPSS and start working
on the numbers. Then verify and check them with Haskell and R

Big robot data systems are interesting and even dangerous as they
get bigger and faster.

Then there is the security of the OS running the robot. Stuxnet has
a lesson to be applied here. Lots of stuff spinning... .

They'd also be cheaper, even at the bulk HDD rate that FB would pay.

A quick on-line search show a spindle of fifty 50GB Blu-Ray discs (2.5 TB) retails for about $100. A 4TB HDD costs about $140. So HDD is actually cheaper per byte of storage. Maybe wholesale price ratios are way different from retail, but I see no reason to assume that. So BluRay doesn't win on price, volume, or access speed. The concerns about moisture and big temperature swings seems odd. Are Facebook data centers exposed to the weather?

Seldom used data sitting in spinning power draining disks has a continuous power cost.
Power and cooling are important data center considerations.

Facebook has an astounding pile of data in picture archives that after a couple months are
only called on once in a while if ever again.

Layers of storage from the modern very quick SSD devices to spinning rust disks to perhaps BluRay
seem to have a place when access time and space considerations come to play. I wish them luck.

One problem with BlueRay, DVD and CDROM media is the lack of data as storage beyond
five years or so. But as a physical form factor goes these little devices do have a lot of potential.
I wish them luck and wish I knew what vendor to invest in.

He suggests a massive company like Google or Facebook will eventually have to take up the task of making Tor scale up to millions of users.

If one of those guys gets their hands on it you can forget about using it to hide anything from the government.

"Here's some bugs we've fixed for you guys. Trust us."

Oh yeah, because the current debug team we can trust so much...

There are two parts..
      * Here is the bug.
      * Here is a bug fix.

The first has a lot of value in an open source community.
The second if taken with blind faith is a potential disaster.

As a pair the time window for attack can be reduced.

Gifts from the NSA are an interesting thing... Some might be triggered
because they have evidence that others have knowledge of the
flaw and are exploiting it. As the need for human intelligence
grows the need for secure communication increases from individuals
(assets) far afield. In that regard bug disclosures would be self
serving but still be quality fixes the Tor community needs.

One important point to me in terms of global security is that
"actions speak louder than words" and if the TLAs like the NSA
pay attention to global bad actors things might find clarity in contrast
to the thought police reaching out four+ degrees of connectivity

Speaking about bad actors... our news media outlets seem to
have abandoned all attempts at quality, completeness and

airtime programming does and unedited content should be available.
It is not obvious how one might edit out the payment for cigars

This has gone to stink with the advent of cable and broadcast
