Security Fix Leads To PostgreSQL Lock Down 100

Posted by samzenpus
from the shut-it-down dept.
hypnosec writes "The developers of the PostgreSQL have announced that they are locking down access to the PostgreSQL repositories to only committers while a fix for a "sufficiently bad" security issue applied. The lock down is temporary and will be lifted once the next release is available. The core committee has announced that they 'apologize in advance for any disruption' adding that 'It seems necessary in this instance, however.'"

As noted, 'this is a prerelease version,' so handle with care. Just remove any existing Flash player and extract the new .so file in /usr/lib/mozilla/plugins (or /usr/lib/opera/plugins)."

Bark Beetles Hate Rush Limbaugh and Heavy Metal 220

Posted by samzenpus
from the tiniest-minds dept.
Aryabhata writes "According to scientists, climate change and human activity have allowed bark beetle populations to soar. They decided to fight the beetles by using the 'nastiest, most offensive sounds' that they could think of. These sounds included recordings of Guns & Roses, Queen, Rush Limbaugh and manipulated versions of the insects' own sounds. The research project titled 'Beetle Mania' has concluded that acoustic stress can disrupt their feeding and even cause the beetles to kill each other."

Lanxon writes "Swaroup Anand, 23, from Bangalore, was fully conscious as he underwent open-heart surgery. An epidural to the neck, administered at the city’s Wockhardt Hospital, numbed his body during the procedure. Dr Vivek Jawali pioneered the technique ten years ago and has recently released a tutorial on DVD, which gives a step-by-step guide to the procedure for other surgeons to watch and learn from."

grrlscientist writes "While living and working as a marine biologist in Maldives, Charles Anderson noticed sudden explosions of dragonflies at certain times of year. He explains how he carefully tracked the path of a plain, little dragonfly called the Globe Skimmer, Pantala flavescens, only to discover that it had the longest migratory journey of any insect in the world."

Big Dipper "Star" Actually a Sextuplet System 88

Posted by kdawson
from the toil-and-trouble dept.
Theosis sends word that an astronomer at the University of Rochester and his colleagues have made the surprise discovery that Alcor, one of the brightest stars in the Big Dipper, is actually two stars; and it is apparently gravitationally bound to the four-star Mizar system, making the whole group a sextuplet. This would make the Mizar-Alcor sextuplet the second-nearest such system known. The discovery is especially surprising because Alcor is one of the most studied stars in the sky. The Mizar-Alcor system has been involved in many "firsts" in the history of astronomy: "Benedetto Castelli, Galileo's protege and collaborator, first observed with a telescope that Mizar was not a single star in 1617, and Galileo observed it a week after hearing about this from Castelli, and noted it in his notebooks... Those two stars, called Mizar A and Mizar B, together with Alcor, in 1857 became the first binary stars ever photographed through a telescope. In 1890, Mizar A was discovered to itself be a binary, being the first binary to be discovered using spectroscopy. In 1908, spectroscopy revealed that Mizar B was also a pair of stars, making the group the first-known quintuple star system."

+ - Why is Google Blocking Tor? 1

Submitted by Bobb9000
Bobb9000 (796960) writes "As I and I'm sure other Tor users have noticed, Google has recently begun blacklisting any query coming from a Tor exit node. There's been some discussion of this, but not very much, and while the Tor FAQ claims this is only a temporary problem, and that Google has taken no positive steps to block Tor, for the past few months I haven't been able to find a single exit node that can use Google. Now, it's possible that recently there's just been a massive amount of automated request activity coming from every Tor exit node, but that seems unlikely. Even if it were true, somehow Yahoo has been able to cope, as it almost always works through Tor. So, why is Google making it harder to be anonymous online? Genuine security concerns, or a dislike for anything that takes away their ability to harvest personal data?"

+ - Can XML save the US Credit Markets?->

Submitted by sixoh1
sixoh1 (996418) writes "The Wall Street Journal Opinion pages have a very interesting tidbit today about the eXtensible Business Reporting Language (XBRL) — can XML be used to improve transparency in the jumbled financial markets and help fix the mortgage market mess by making all of the information searchable? The director of Edgar Online thinks so: 'Philip Moyer, who runs the Edgar Online service that distributes SEC data, studied more than 500 mortgage-backed securities priced between 2006 and mid-2008. He found there were only 600 relevant data points needed to assess the risk of a mortgage, which is many fewer than the tens of thousands of factors used to report on stocks. "This crisis has proven that lack of transparency ultimately destroys a market," Mr. Moyers said.'"

+ - At Least 20 Dead in Virginia Tech Shooting

Submitted by StarvingSE
StarvingSE (875139) writes "Virginia Tech police state that at least 20 are dead in a campus shooting school officials are describing as a "monumental tragedy." From the article:

"Today the university was struck with a tragedy that we consider of monumental proportions," said university President Charles Steger. "The university is shocked and indeed horrified."

The attacks mark the worst school shooting incident since 1999 when Dylan Klebold and Eric Harris killed 12 students and a teacher before killing themselves at Columbine High School in Littleton, Colorado


This story is a little off-topic on a technology-related site, but I'm sure quite a few readers attend or are alumni of Virginia Tech."

+ - Effectiveness of Education Technology - NOT

Submitted by CETS
CETS (573881) writes "The National Center for Education Evaluation and Regional Assistance produced this major study of the effectiveness of education technology. Mandated by Congress, the report uses scientifically based research methods and control groups to focus on the impact of technology on student academic achievement. The main findings of the study are:

  • Test scores were not significantly higher in classrooms using the reading and mathematics software products than those in control classrooms.
  • There was substantial variation between schools regarding the effects on student achievement. Although the study collected data on many school and classroom characteristics, only two characteristics were related to the variation in reading achievement. For first grade, effects were larger in schools that had smaller student-teacher ratios (a measure of class size). For fourth grade, effects were larger when treatment teachers reported higher levels of use of the study product.
