Comment Re:Vigilances (Score 2) 481

At a sit-in one occupies a space owned by a for-profit company without spending a significant amount of money. This space could be used to generate a normal stream of revenue if customers were able to purchase goods or services and move along. By preventing the proprietor from bringing in a normal amount of customers' money, sit-ins definitely result in a loss of revenue and likely tack on an added cost; it takes a few bucks more to ventilate and condition a building full of people than to hold an empty building at a steady state.

With few exceptions (e.g. your parent/teacher teaches a class or chairs a club which no other teachers offer) the potential academic conflict of interest prevents this situation from occurring.
A child in such a situation often attends the lectures of the class but is graded by another teacher familiar with the curriculum.

Comment Re:"not air conditioning the gym from 9pm-3am" (Score 1) 122

HVAC geek here,
I recognize the parent poster's humor, but take exception with the conclusion that more air conditioning capacity would be required.

The cooling system for a gymnaisum should (1) provide enough fresh air for the room's expected occupancy, (2) maintain a comfortable temperature between the lowest seating and the highest seating, and (3) remove water vapor provided by sweaty athletes and heavy-breathing spectators.
A dehumidifying air handler should take care of (1) and (3), while destratification fans would blend the air for consistent feel over the height range described in (2).

During a LAN party, there should be fewer occupants in the space than during, for example, a basketball game.
These occupants would be seated and thus lower to the ground than running and jumping athletes or spectators in bleachers.
Overhead lighting levels could be reduced to limit glare on monitors, probably down to the density required by code for emergency egress.
From 9pm to 3am, the building envelope would not be subjected to the heat load of solar radiation.

If destratification fans were turned off and CO2/H2O sensors were used to control the outside air intake and dehumidification stages of the air handler, respectively, the cost of cooling overnight LAN parties may be less than the cost of cooling the space during its designed use.

Comment Killer App? (Score 5, Insightful) 281

Ubuntu has gone soft. Its recent changes pushed me back to Debian. Why does it have to be targeted at social media, online music sales, etc.? Unless it has something to give that isn't better-known on another platform, there's no incentive for users to switch.
TFA is slashdotted or I'd cross my fingers hoping for just that feature.

Comment Drivers vs Pilots (Score 1) 302

Pretend this program gets off the ground.
Bad drivers tend to survive crashes in good cars.
Bad pilots don't do quite so well, excepting the occasional embarrassing ground roll on landing.
Helicopters require more complicated controls than planes.

There would be a significant population of competent truck drivers who would struggle to pilot an ultralight helicopter-truck.
