Submission + - Adobe Toughens Sandbox Security in Reader, Acrobat (securityweek.com)

wiredmikey writes: Adobe has beefed up the security capabilities of its Reader and Acrobat software with a more robust sandbox and new security mitigation features, the company said today.

Adobe Reader XI and Acrobat XI, which shipped this week, include a new whitelisting framework, cryptographic capabilities, and a feature that forces all of the DLL files loaded to use ASLR (Address Space Layout Randomization), even if the files were not originally compiled with ASLR enabled.
The biggest change in Reader and Acrobat XI, however, is in the sandbox. The original sandbox in Reader X focused on "write protection" to prevent attackers from installing malware on to the machine or recording user keystrokes. Reader XI now restricts "read-only activities" to prevent attackers from reading sensitive information.

Adobe said that since they added sandbox protection to Adobe Reader and Acrobat, they have not seen any exploits in the wild that break out of the Adobe Reader and Acrobat X sandboxes.

I may end up putting a solar pre heater on the system. In SE Alaska it's a pretty marginal exercise but for most of the civilized world, it's a no brainer.

coldwetdog - have you ever checked out http://builditsolar.com/ ?

a kazillion homemade solar designs, including a lot of variations on a simple drain-back system which doesn't require antifreeze, but instead uses an unpressurized system that simply turns off the circulator pump and lets the water drain out of the collector and back into the insulated holding tank under situations where you would face freezing or heat loss...

i don't think that 25 year figure is correct. there seems to be quite a bit of FUD on the net about 'useful life' but this seems to be the only way the manufacturers can have the economics make sense. really, you have to look at warranties to get a sense of real world lifetimes.

i just took a quick and unscientific survey of the internets, and the tankless designs i saw have 1 year labor and 5 years parts warranty. i very much doubt that the units will last 20 years past their warranty period without continued repair.

my personal experience is that tankless heaters are very fussy and need much more maintenance than a tank heater, which needs almost none besides the replacement of the sacrificial electrodes occasionally, and then only if you want the tank to last far past the 10 year warranty.

one site i saw talked about a 20 year 'useful life' of the tankless heaters, but went on to explain that anyway when things do break, every single part is repairable or replaceable. unfortunately, at current plumber and parts cost, this can easily effectively triple or quadruple the unit's initial cost. also, at least rinnai, a major japanese manufacturer, says the units should be inspected and maintained every year, so you can add *at least* ( $100 * expected service life in years) to the cost of the units. that tank heater with the 10 year life and no service requirements is starting to sound quite a bit better, yes?

in summary, i think your figures are wrong- the info on the net, as well as my personal experience seem to suggest that tankless is a very expensive alternative.

again, a better solution is to insulate, consider solar (homemade equipment can set you up with a system to heat water and your house for under $1000!), and look at other, more cost effective technologies such as grey water heat recovery systems (http://energy.gov/energysaver/articles/drain-water-heat-recovery), which recover much of the heat from baths/showers, the biggest hot water use in a house, and have potentially only a couple of years payback.

i do wonder where you got that 25% increased efficiency figure, as that seems somewhat oversimplified as well.

there is way too much emotion in the energy conservation world. often the most effective solutions are not the sexy ones.

Water heaters should not be running at all unless someone is taking a shower. It is called on demand hot water, tank style heaters need to go. Normally this is gas fueled, not electric.

actually, on demand water is only slightly more efficient than a well insulated water tank heater, and i think the tradeoffs make it not worth the switch. effectively, the tank acts as an energy storage system, which means that you can use a much slower flow of energy over a longer time to heat the water.
this instantaneous demand requirement means that the equipment is much more complicated and expensive to make, needs regular servicing, and has a shorter lifetime, meaning even more manufactured costs, not to mention reinstallation costs. also, since instantaneous heating demands are *much* higher than conventional heater requirements, often a new exhaust flue, and sometimes even a new incoming gas pipe of larger size must be run for the install.

it is more important to make sure your existing heater and all your hot water pipes are very well insulated, and if you really want to spend money in pursuit of efficiency, get a solar water heating system if your climate and situation allow.

Comment mattresses--servers--desktops--phones--screens (Score 2) 331

in order of importance, fragility, price and density.

put some spare mattresses on the floor/sides of the uhaul and put your servers down there. next to each other. (you do have mattresses, right? you're a retreat center and a big fire is coming...)
next desktop boxes, lined up next to each other.
on top networking and ip phones, combined into a few bags/pillowcases etc. these, particularly the phones are light and wont damage each other.
next screens, wrapped in blankets and stabilized. you'll find the screens most fragile, and requiring the most careful packing, but they are also not so expensive to replace so don't worry too much.

come to think of it, you probably can throw some meditation pillows in there between the screens and anywhere else you need them.

that should give you a fast pack of everything critical. you also hopefully have made offsite backups, though.


Submission + - YouTube Partially Unblocked in China (ktsf.com) 1

hackingbear writes: After China unblocked certain sensitive keywords in search engine baidy.com last week, YouTube is now partially, quietly unblocked (Google Translate.) Users inside China can, without bypassing the Great Firewall, visit the site, search for sensitive keywords, and see uncensored results and comments. The videos themselves, including those not related to politics, remain blocked, however. Given that the Chinese government likes to make major changes in gradual, experimental steps, it is unclear what this round of Internet loosening will lead to eventually. At the meantime, many netizens in the country express their welcome of the moves as a good start through microblogging.

Submission + - As many as one in four websites may be blocked in Iran (viewdns.info)

hugheseyau writes: ""Internet usage in the Islamic Republic of Iran has increased significantly since the country's first Internet link went live in 1993, second only now to Israel when comparing the percentage of the population with Internet access in the Middle East. This presents a problem for a regime with a well documented history of press censorship as many users see the Internet as an opportunity to have their voices heard outside the reach of the Iranian Government. In response, in 2006 the Iranian Government began to dramatically increase its censorship of the Internet In Iran.

This article examines the state of Internet Censorship in Iran in 2012 by conducting a survey to determine whether top sites across all categories of the Internet are censored in Iran. The results of this survey were quite shocking, revealing a large percentage of websites are blocked in Iran""

Submission + - Congress Capitulates to TSA; refuses to let Bruce Schneier testify (schneier.com)

McGruber writes: Following up on the earlier Slashdot story "Congress Wants Your TSA Stories" (http://yro.slashdot.org/story/12/03/23/2312228/congress-wants-your-tsa-stories), earlier today, the U.S. House of Representatives Committee on Oversight and Government Reform and the Committee on Transportation and Infrastructure held a hearing titled 'TSA Oversight Part III: Effective Security or Security Theater?' that was streamed line by CSPAN (http://www.c-span.org/Events/House-Hearing-Examines-TSA-Security-Initiatives/10737429331-1/).

In a blog update (http://www.schneier.com/blog/archives/2012/03/congressional_t.html), Bruce Schneider says that "at the request of the TSA" he was removed from the witness list.

Bruce also said "it's pretty clear that the TSA is afraid of public testimony on the topic, and especially of being challenged in front of Congress. They want to control the story, and it's easier for them to do that if I'm not sitting next to them pointing out all the holes in their position. Unfortunately, the committee went along with them."


Submission + - Aeronautical 3D Printing: Design, Print, Fly (3dprinterhub.com)

jcho5 writes: Last August, a team of aeronautical engineers at the University of Southampton designed, built, and successfully flew a UAV (unmanned aerial vehicle) plane within seven days using 3D printing technology. In the video capturing the flight, a small airplane is darted into a vast blue horizon off the platform of a slingshot-mechanism, and immediately the shrill of the plane’s electrically-powered engine drowns out the static caused by wind. The roaring abates as the airplane gets smaller and smaller on the screen.

The goal of the project was to show how 3D printing would revolutionize aeronautical manufacturing. With the help of 3T RPD, a 3D printing firm in the UK, the engineers at Southampton were able to produce a plane using three steps—draw, print, fly; they drew the design on a computer CAD program, printed the parts of the UAV out of hard nylon, snap-jointed the pieces together, and watched the design—drawn only five days prior—rip through the skies.

The question is why aren’t bigger manufacturers investing in this technology? Well, it turns out they are. Companies like Boeing, one of the world’s largest airplane manufacturers, and NASA are already implementing 3D printing technology into their designs. The Boeing Phantom Ray—an unmanned combat air vehicle—for example, is part of the company’s efforts to utilize 3D printing.

At the beginning of the 20th century, industrialization and assembly lines provided every middle-class American the means to own a Ford Model T. Would it be going too far to say that 3D printing will revolutionize aircraft manufacturing in a similar way?


Submission + - China Unblocks Sensitive Keywords (baidu.com)

hackingbear writes: Reports from oversea (in Chinese) and Hongkong-based Chinese media report that China appears to have unblocked several sensitive political keywords. Using Baidu.com the country's leading search engine, users within the mainland border find, in Chinese, uncensored web page links and images using keywords like Tiananmen and "June 4". (Readers can click on the first one to view the images.) Given that the unblocking of these most sensitive keywords (of all) comes one week after Chinese Premier Wen Jiabao publicly denounced left-wing leader Bo Xilai's movement of "striking down the ganster while reviving the red culture" as going down the path of Cultural Revolution, it could signal the silent start of a major political change. Separately, the Financial Times reports that the Premier has proposed the rehabilitation and re-evaluation of the 1989 Tiananmen Incident, but he met strong resistance from the left-wing fraction led by Bo. Bo has been sacked following the denouncement. Also the linked sites of the search result appear still being blocked and that other keywords, such as "Dalai Lama", are still being censored.

Actually, it isn't. In 1844, in the interests of segregating passenger train and road traffic, a rail tunnel was built under the roadbed of Atlantic Avenue, in what was then the independent city of Brooklyn, New York. There is a reply to the OP suggesting that Liverpool has some earlier tunnels than this, but in any case, it would seem that Brooklyn significantly predates the London underground train system.

Americans Elect's board is primarily staffed by the far right. This is simply an effort to split the liberal vote. Go look it up; it's pretty easy to find that Americans Elect's board alone makes it untrustworthy.

actually, this is FUD, and isn't at all correct. the board are political and money people, and of the independent / moderate / better world persuasion.

Peter Ackerman, the chairman and a founder, works on wall street, and also was previously associated with Freedom House, which was started by Eleanor Roosevelt, and which does research and advocacy for human rights and political freedom. He also has co-founded the American Center on Nonviolent Conflict, which "promotes the study and utilization of nonmilitary strategies by civilian-based movements to establish and defend human rights, social justice and democracy".

I'm not sure where you get far right and untrustworthy out of that, but if you mean that Americans Elect are trying to provide a voice that isn't of and filtered by the existing two dysfunctional self interested politics parties, i'm all for that kind of untrustworthy.
