Comment Re:How Is This Bad? (Score 1) 383

This is a load of horse shit. Yes, atomic mercury is bad for you. However, there are several useful and demonstrably non-harmful mercury compounds. "There's no safe amount of arsenic exposure!" "Hey, your cellphone contains some gallium arsenide transistors. OMGYERPOISONED"

Comment Nook Color handles 99% of my PDFs (Score 2) 254

The built-in PDF reader on the Nook Color is decent. It drains the battery faster (maybe 2x or 3x?) than reading epub files but is still quite usable. I've only ever had trouble with one PDF: there was one page with a TON of overlaid vector images and it wouldn't render correctly; all pages after that page were missing images entirely. Otherwise it's been a fine machine.

Comment Re:13 years? (Score 1) 385

While it'll be nice to get native lambdas, the above example is a bit contrived; it's a lot prettier than this in current C++. With boost's lambda:

vector<int> foo(5, 0);

// one example
int n = 42;
for_each(foo.begin(), foo.end(), _1 = var(n)++);

// and another
for_each(foo.begin(), foo.end(), cout << _1 << '\n');

The syntax isn't perfect, but can be very handy for throwing together prototypes, descriptive code, etc.

Comment Re:Isn't 5/13' less than 55%? (Score 1) 664

The summary incorrectly states "5 ft" but the other news releases state "5 m." The fuel rods are 4.5m long, so the implication is that 100% of the hanging fuel rods are exposed. Any that fell/slumped to the bottom of the pressure vessel are, of course, probably 100% covered since there is still some water in the vessel.

Comment The one-router solution (Score 2) 520

1. download dd-wrt and flash your router; a decent one with a full 8 MB of flash is probably ideal.
2. set it up to have two SSIDs; one will be encrypted, one will not. DO NOT BRIDGE THEM. (You don't want the open wifi AP traffic to be able to reach your other subnet.)
3. set up traffic rate limiting (QoS) on the router; put the public subnet traffic into the "bulk" (i.e., low) priority and your private subnet's traffic into something higher.
4. turn it on, test it well, and smile because you're doing well and doing good.

Submission + - Google Video Race Against Time Goes Distributed (nicalderton.com) 3

Bottles writes: Following Google's announcement to shut down Google Video (previously reported on Slashdot), the Archive Team has inspired a group of volunteers to join together to preserve as much of the content as possible: some 2.5 — 2.8 million videos. In a few short days the effort has evolved from a simple wiki suggesting people band together to download automatically generated lists of video ID's via a crude automated script to a centralised, distributed batch management system which assigns unique video ID's to volunteers' machines for download. The system, developed by Alex Buie in less than 48 hours, is now the recommended way to preserve the content and to avoid duplicate downloads. Watch videos roll in live here thanks to PubNub and read on to find out how you can help.

The clock is ticking to download as much as possible by the 29th of April — before Google throws the switch. Thereafter, Archive.Org has assigned a 140TB buffer for uploads into its 1 petabyte of storage space to house the preserved content. After the cutoff, downloaders can offload their content at their leisure.

The team from around the world, spearheaded and coordinated by Jason Scott, has been working solidly and altruistically. No selection criteria have been applied to the content; the idea is to preserve everything, if possible; however various team members have been working on collating word lists for searches: by concept, year, country etc. In this way they have a growing master list of some 2449000 unique video ID's to be processed of which around 15% are already saved.

You can help out. Please visit the wiki and the #googlegrape irc channel on EFNET, download the scripts and donate a little bandwidth and storage to preserve as much as possible before the cutoff date. There is less than a week left.

Comment Linked nuke article is full of errors (Score 1) 177

The linked article about the nuclear plant problems in Japan is chock full of technical errors and omissions. He skips the primary danger of exposed fuel rods, the danger Japan is facing: thermal damage to the fuel rods themselves, prior to the total meltdown stage, means your steam pressure releases now contain primary radionuclides! He states that the melted fuel rods aren't hot enough to melt steel and concrete, when they most certainly are! (They melted sizeable chunks of the containment vessels at TMI and Chernobyl.) He fails to correctly describe what emergency core cooling systems do and how. He miss-states the actual danger of graphite-moderated reactors: it isn't that graphite is flammable, it's that you're using it as a moderator (as thus, water as some of the neutron absorption) and that makes the system inherently unstable. Once you reach the point of worrying about the graphite burning, you're way past the tremendous explosion/meltdown phase.

Comment Nothing to see here (Score 3, Insightful) 506

As someone who works in the solar and wind controls business, let me state: this is not a surprise or really even a problem. People who install big wind and solar systems understand, because of the payback horizon of such installations, the limitations of the local distribution system. It is completely normal for big turbines to have to feather/furl/divert themselves during strong wind. The owners and installers design for this. It's factored into the payback time of the project!

The problem here is the sensationalist reporting. Yes, we need better electricity distribution systems for distributed generation, but we in the industry know that. We've known it for years. The guys who financed and installed the system at Columbia River Gorge almost certainly knew it.

So, yes, pump money into building bigger lines in the right places, but that's something we've been doing for more than fifty years. Generation locations are rarely at consumption locations, after all, and that was true for coal, natural gas, etc., just as it is for wind, hydro, and solar. The only problem here is that our 1990's generation locations aren't where tomorrow's generation locations are.

On Social Networks, You Are Who You Know 171

santosh maharshi writes "On social networks like Facebook, even if you have kept your profile very private, people can just look at your friends list and infer lots of vital information about you. Most of the social networks like Facebook and LinkedIn allow people to see your picture and your friends list as part of the open access for visitors (the article says that only 5% of Facebook users have bothered to hide their friends list). In a study titled You Are Who You Know: Inferring User Profiles in Online Social Networks (PDF), conducted by Alan Mislove of Northeastern University and his colleagues at the Max Planck Institute for Software Systems, an algorithm was tested that can accurately infer the personal attributes of Facebook users simply by looking at their friend lists. 'At Rice [University], the algorithm accurately predicted the correct dormitory, graduation year, and area of study for the many of the students. In fact, among these undergraduates, researchers found that “with as little as 20 percent of the users providing attributes we can often infer the attributes for the remaining users with over 80 percent accuracy."'"

Comment Re:Free to look--but what if your system is locked (Score 1) 821

My solution:

  • main partition is Win XP
  • second tiny partition for /boot
  • rest of the drive is an encrypted LVM partition with Linux

When I go to travel, I edit my grub menu and enable (uncomment) "hiddenmenu", make sure the default is to boot to XP and the default timeout is just a couple seconds. If you want more stealth, force the machine to boot XP always, recoverable only if you boot off a Live CD (Knoppix, et al) and go re-enable booting to Linux. If you want even more, put your grub and /boot on a thumb drive.

Agent boots up the laptop, perfectly benign Win XP computer. If they want to clone the drive and examine it off-line at their leisure, they're more than welcome.

Of course, I've long ago forgotten my encryption password, so I can't boot into it even if compelled by a court. I guess that makes me a terrarist.

An anonymous reader writes: We've got a winner in the Pentagon's $3.5 million all-robot street rally, the Urban Challenge. Three, actually. WIRED reports that 'bots from Stanford, Virginia Tech, and Carnegie Mellon all completed the course within the six-hour time limit.
