In that 0.73 seconds the payload would accelerate to 3 kms/sec The continuous acceleration would be 3000/9.8/0.73= 417 Gs. That is sure a lot of Gs. Much more than the 3.2 the shuttle produces.
Newer howitzers can have a muzzle velocity of almost 900m/s. They achieve that velocity in a barrel length of only 8.52 meters (55 calibres X 155mm). So 3 km/s in 1.1 km doesn't seem like a big ask.
Before Carly Fiorina destroyed HP they used to be the leader in printers (or at least in the very top tier). Now they crank out plastic pieces of shit that break after a year, are difficult to repair using off-the-bench tools, and try to market a new toner cart to you when the old one is still at 20% capacity. Seriously, our LaserJet 4200 will not go into powersave mode when it is telling me to order a new cartridge with 1/5th the life remaining. It is very annoying.
Another trick I've heard of with the latest HPs is they're putting region protection on their cartridges, like with DVDs. A cheap but legitimate HP cartridge imported from Asia was not allowed to work on an Australian HP printer.
Why isn't some sort of non-stick coating such as Teflon not an option?
On Australian TV some time ago was a piece about the uses of liquid lanolin, a by-product of the wool industry.
When applied to the hulls of day trip tourist vessels the lanolin not only acted as a non-toxic antifouling agent but it reduced fuel consumption by a significant amount (from memory something like 10% to 20%).
However, they had the luxury of being able to beach/dry-dock the vessels to reapply the coating as needed.
I always tell our new starters not to share or write down passwords. Of course some of them will - generally the higher paid ones.
Schneier recommends that you do write down passwords... but recommends that you keep them in your wallet, not on a Post-it Note stuck on the front of your monitor.
He also recommends that you disguise them by mixing them with other numbers and passwords.
The marginal increase in cost from the cooling is canceled out by the heating gains. That is, for every extra dollar I spend cooling heat that I produced with the light bulbs, I save at least an extra dollar off my heating bill.
While 1 kWh of lighting produces 1 kWh of heat, a similar amount of power used to run a heat pump or reverse cycle air conditioner produces around 3 kWh worth of heating.
Waste heat is almost always a second rate heating solution.
The most-successful virus struck Europe in the mid-1200s, killed 40% of the people, and created a shortage of labor that allowed the serfs to free themselves and demand pay. Thus the middle class was born.
What did these viruses have in common? They were very virulent, killing the host quickly, but it didn't matter because their RNA code was spread via fleas.
A number of people doubt the bacterial bubonic plague/rats/fleas explanation due to the rapid manner of spread of the disease. A viral haemorrhagic fever, possibly airborne, is given as a more likely alternative.
Wouldn't do not to reference related work such as the Stanford Camera Array - video here showing the multitude of neat tricks that can be done by processing images from multiple apertures into a single image:

The advent of inexpensive digital image sensors has generated great interest in building sensing systems that incorporate large numbers of cameras. At the same time, advances in semiconductor technology have made increasing computing power available for decreasing cost, power, and package size. These trends raise the question - can we use clusters of inexpensive imagers and processors to create virtual cameras that outperform real ones? Can we combine large numbers of conventional images computationally to produce new kinds of images? In an effort to answer these questions, the Stanford Computer Graphics Laboratory has built an array of 100 CMOS-based cameras.
I can see a scenario where the entire walls and ceiling of a room are a distributed camera, and the user could use a joystick controller to move the view point all around the room as required.
