I don't think that it delivers 1,600J, so much as it consumes 1,600J. Quoting the numbers you printed:

1.1g sabot
300 m/s (above 250 m/s, so let's be generous).

E = 0.5*M*V^2, so
E = 0.5*1.1*300*300 = 49,500mJ = 49.5J. So, the muzzle energy is about 1/30th of the energy it appears to be using.

Poking around a bit, I found a variety of velocities and masses for paintballs, so I'll posit that the muzzle energy of a paintball pellet varies between 12J-20J. So, assuming the pressure system is imparting similar energy as a paintball gun, this guy's rail is imparting a maximum of about 30J-38J to the slug, or about 1/50th of the energy consumed. No wonder his graphite sabot didn't reach a target.

it's also cyclical based on I think a 5 year average of the price of oil - that means it's going to start going down next year as gas starts to plummet

It's based on the fund income, which doesn't necessarily correlate to oil prices. The Alaska Permanent Fund Corporation manages a *widely* diversified portfolio. An oil income deposited into the fund becomes a part of the principal and may contribute to the income.

The permanent fund is ultimately a rainy day fund. The distribution of the dividend from the permanent fund can be redirected into the state budget when it's needed. It's difficult to do politically, though.

Recognizing, I suppose, that the Permanent Fund dividend will be difficult to touch, there's a Statutory Budget Reserve (~1.7B, easy to draw from) and a Constitutional Budget Reserve (~$10.1B, harder to draw from). There are also a bunch of smaller savings accounts that do things like offset the high cost of electricity in the villages. All told, Alaska has about $70B in savings, and about $20B of that can be used directly for the budget. That $20B can fund the government at it's current budget for about 4 years without any of the permanent fund earnings.

At worst, hardware manufacturers will make the WiFi portion of the device untouchable from the rest of the firmware, or perhaps requiring signed binary firmware for the WiFi transmitter.

It would be a nice compromise position, but the one of the FCC Documents, in describing the reporting requirements, specifically asks how the device prevents loading "third-party firmware, such as DD-WRT."

I don't think that this does what you think it does. The FCC, in an advisory document, specifically mentions the DD-WRT OS. From Software Security Requirements for U-NII Devices:

What prevents third parties from loading non-US versions of the software/firmware on the device? Describe in detail how the device is protected from “flashing” and the installation of third-party firmware such as DD-WRT.

The FCC is trying, with this rule, to prevent any modification to future devices. From the same document:

An applicant must describe the overall security measures and systems that ensure that:

  • 1. only properly authenticated software is loaded and operating the device; and
  • 2. the device is not easily modified to operate with RF parameters outside of the authorization.

The description of the software must address the following questions in the operational description for the device and clearly demonstrate how the device meets the security requirement.

The same document also suggests that there be strong security between the regulated device and the manufacturer's website to verify installed software. How does this not eliminate the use of Tomato or OpenWRT? If you expect to use one of the alternate firmware on future devices, this proposed rule will absolutely affect your ability to do so.

I've a '97 Chevy 3/4 ton that has been rock solid. It's needed two fuel pumps, a water pump, a clutch, axle seals and the blower motor switch over a life (so far) of 240,000 miles. It needs a little work right now, but not more than about $400 in parts. I *want* to replace it with something newer, but I just can't bring myself to replace something that's been so reliable. Also: only light surface rust on the frame with none on the body.

Child labor laws were not brought about singularly by unions:

Child labor began to decline as the labor and reform movements grew and labor standards in general began improving, increasing the political power of working people and other social reformers to demand legislation regulating child labor. Union organizing and child labor reform were often intertwined. . .

. . .and that's a generous assessment of union involvement with child labor laws in the US. Child labor had been on the decline, but the National Consumer League had been lobbying the US congress for some time, and finally made progress when sentiment changed largely due to the scarcity of jobs.

This success arose not only from popular hostility to child labor, generated in no small measure by the long-term work of the child labor committees and the climate of reform in the New Deal period, but also from the desire of Americans in a period of high unemployment to open jobs held by children to adults.

This is not to say that unions weren't important, but they were as much a part of a larger social movement as they were a cause.

Submission + - Sourceforge staff takes over a user's account and wraps their software installer (arstechnica.com) 11

An anonymous reader writes: Sourceforge staff took over the account of the GIMP-for-Windows maintainer claiming it was abandoned and used this opportunity to wrap the installer in crapware. Quoting Ars:

SourceForge, the code repository site owned by Slashdot Media, has apparently seized control of the account hosting GIMP for Windows on the service, according to e-mails and discussions amongst members of the GIMP community—locking out GIMP's lead Windows developer. And now anyone downloading the Windows version of the open source image editing tool from SourceForge gets the software wrapped in an installer replete with advertisements.
