Ebola Nose Spray Vaccine Protects Monkeys

Kurast Re:Technicalities (198 comments)

For a population size of 6 billion, confidence interval of 95%, expected mean distribution of 50% (most conservative) of infection ratio, a sample size of 9 gives us a margin of error of 32% (try yourself: http://www.raosoft.com/samples...)
Given 100% efficacy, it is highly significant, well outside the margin of error.
Is is significant even for 98% confidence.

ARIN Is Down To the Last /8 of IPv4 Addresses

Kurast Re:We are not anywhere near running out of address (306 comments)

Because there is a very high one-time-only cost involved in switching to ipv6, compared to a small running continuous cost of continuing in ipv4, and for now, it is advantageous to become in ipv4. No one wants to be the one to switch first.

Just think of all sort of problems large ISPs will have to deal in terms of support if they switch to ipv6, in terms of phone service, visits, substitution of cable modems, support for old machines running none/bogus ipv6 implementation.

Just think of all the programs coded years ago, with ipv4 hardwired in (I know 4to6, but your client does not).

Not easy as flick a switch.

This seems like a super capacitor and a battery put together. You charge the capacitor, and it slowly charges the battery.

EU Plastic Bag Debate Highlights a Wider Global Problem

Kurast Re:Solution (470 comments)

I live in Brazil and sometimes I walk to the market.
Some upper end markets here give you a paper bag with handles, like this one:
I prefer those to plastic ones. They easily handle 10kg(about 25 lbs, for americans), where the plastic ones barely get 2kg(5 lbs) without punctures. Also they are very sturdy, and survive minor rain.
With two of those paper bags I can take the equivalent of ten or more plastic bags, and they don't hurt my fingers like the plastic ones do.

Brazil Blackout

Kurast Kurast writes  |  more than 5 years ago

Kurast (1662819) writes "Combine a 60 Minutes piece on cyber terrorism on Sunday night with a Brazil blackout that happened today, November 10, 2009, that has "tens of millions of people" without electricity and we have a new threat at the forefront of everyone's minds. The full story about the Brazil blackout can be read at NPR.org in the article "Blackout Leaves Millions Without Power in Brazil" by Mark Memmott (http://www.npr.org/blogs/thetwo-way/2009/11/brazil_blackout_electricity.html) . According to the article power is out in much of San Paulo and Rio de Janeiro.

The 60 Minutes piece from Sunday, November 8, (http://it.slashdot.org/story/09/11/09/0012226/Massive-Power-Outages-In-Brazil-Caused-By-Hackers) blamed blackouts in Brazil in 2005 and 2007 on cyber terrorism and stated it is becoming a serious threat to the United States. With more and more utilities becoming controlled by computers a strike against the power grid in the U.S. is rising to the top of possible terrorist attacks. The 60 Minutes piece goes into greater detail on the effects of an attack on the electricity grid of a major U.S. city."
