Do the math. The top end of the range from the article was $40,000 for housing an inmate 24 hours / day, 365 days a year. That is $4.56 per hour for inmates.
At $7,000 per year for a school, 200 days a year for about 7 hours a day. That is $5.00 per hour for school kids.

theodp writes "'I've been on teams that eat together every day,' writes Joel-on-Software Spolsky, and it's awesome. I've been on teams that don't, and lunch every day is, at best, lonely.' Spolsky is firmly in the camp that believes where and with whom we eat lunch is a much bigger deal than most people care to admit. 'There's a lot of stuff that's accidental about Fog Creek and Stack Exchange,' he concludes, 'but lunch is not one of them. Ten years ago Michael and I set out with the rather ambitious goal of making a great place to work. Eating together is a critical part of what it means to be human and what it means to have a humane workplace, and that’s been a part of our values from day one.'"

lee1 writes "Physicist Axel Kleidon of the Max Planck Institute for Biogeochemistry
in Jena, Germany has shown that it is a mistake to consider the wind and
waves to be truly renewable energy sources. Build enough wind farms to
replace fossil fuels, he says, and we would reduce the energy available
in the atmosphere and actually accelerate climate change. We know from
thermodynamics that only a modest fraction of the solar energy reaching
Earth is available as 'free energy' we can use, taking the form of
winds, ocean currents, and lifting of evaporated water. The rest becomes
heat, which is not available to do work. By building wind and wave farms, we
will be converting part of the sun's useful energy into thermal energy.
The effects of this would probably show up first in the wind farms
themselves, where the gains expected will be less than predicted as the
energy of the Earth system is depleted. Kleidon’s calculations show
that the amount of energy which we can harness from the wind is reduced
by a factor of 100 if you take this into account. In addition, sucking that much energy out of the
atmosphere will alter precipitation, turbulence and the amount of solar
radiation reaching the Earth's surface. The effect
will be comparable to the results of doubling
atmospheric concentrations of carbon dioxide. Even current photovoltaic
designs will contribute to global warming, because they
convert only a small fraction of the light that hits them converting the rest to heat that warms the environment."

Razgorov Prikazka writes "A Dutch-based company from Groningen is trying to create a potato race that is able to survive in a saline environment. The first test-batch was just harvested (English translation of Dutch original) on the island Texel and seem to be in good shape. The company states that rising sea-levels will create a demand for halophile crops. I do wonder if one still has to put salt on ones potatoes when they are grown in salt water."

tlhIngan writes "The US Air Force, having purchased PS3s for supercomputing research, is now the latest victim of Sony's removal of the Install Other OS feature. It turns out that while their PS3s don't need the firmware update, it will be impossible to replace PS3s that fail. PS3s with the Other OS feature are no longer produced since the Slim was introduced, so replacements will have to come from the existing stock of used PS3s. However, as most gamers have probably updated their PS3s, that used stock is no longer suitable for the USAF's research. In addition, smaller educational clusters using PS3s will share the same fate — unable to replace machines that die in their clusters."
In related news, Sony has been hit with two more lawsuits over this issue.

At least 50% of my paychecks would be converted into tokens and put into one of many Neo-Geo machines at the arcade when I was in high school. It's good that my favorite old games finally have an anthem.

Fortunately for us, the FAA has imposed the honor system as our next best defense against terrorism. Hopefully this will allow them to increase the volume of non-bladder liquid I'm allowed to take on planes.

reporter would be caught with in a war zone or covering any armed action anywhere. What started out as a tongue
in cheek project for April Fools wound up being quite the successful demonstration of concept. It features a fully functional
trigger; it has controls for operating the shutter and auto focus; and for the patient shots, it has a mounted bipod. Carry sling optional."

Zugla writes "With google and yahoo's online maps becoming more powerful and easier to use and gps units with built in maps becoming the norm, users are beginning to expect maps and map data in all sorts of applications. I produce automatic market reports which are distributed via email in pdf form and I would like to include annotated maps showing comparable locations and other data. Because including these maps in a distributed (not free) report would be a form of republication, I do not believe I can use google (terms of service) or yahoo's (terms of service) offerings. Are there other sources of free or low cost map or map data?"
