Comment: Re:Equally tiny UPS? (Score 1) 180

These low power PC's are opening up new opportunities for UPS's, namely that they all run off low voltage DC (nominally 12V) and open up the possability of a 12V UPS. It saves on the inverter required in the UPS, and increases the overall efficiency.

For a device like this with a variable input voltage you can run it directly from a 12V SLA battery, and then keep the battery topped up with a decent mains charger rated to higher power than the PC. You can generally do the same thing with access points and 12V network switches, and any 5V devices can be run from a $5 step down DC-DC converter.

The only problem I've had with this method is 3.5inch USB Hard Drives, as they usually require a well regulated 12V supply. For those I bought a fancier buck-boost DC-DC converter, they were a little pricier and harder for find than, but still quite reasonable.

In the end you may have 30W worth of devices hanging from the SLA batteries, then just buy a multistage charger rated to the next higher power - eg 30W = approx 2.5A @ 12V, so get a 3 or 4amp charger. You can expand to as many parallel as you like, all it does is slow down the recharge time.

I've seen studies on that before.

One of the best ways to seed the oceans is with the addition of iron based minerals. Plants in the food chain need this to grow, but it's very scarce in the ocean. Historically there was a natural seeding process as iron laden dust was blown off the coastlines, but human development has reduced that source.

In Australia we get a Strata Title deed, with common shared assets managed by a strata management company.

For simple blocks subdivided into a few houses, the homeowners can form their own strata company with little to no costs. For apartments buildings they generally employ a third part to manage it, and residents will then pay monthly strata management fees.

I used to build & configure production reporting systems for industry, and the increase in complexity on the math was freaking painful when you had to take in to account daylight savings. Instead of assuming 24 hours in a day, you would always have to calculate "day end minus day start".

These methods would handle leap seconds just as well, but the cost to performance is massive for such a rare event.

It was a terrible situation but to put things in perspective, this kind of incident is incredibly rare in Australia and only 2 poeple died. If you had concealed carry, there would be orders of magnitude more accidental deaths. Doesnt seem worth it and the gun controls we have here generally do a good job.

Not true. At those powers, a reflection of any surface can be powerful enough to blind. There will be a lot of collateral damage.

Just remember, lasers in the milliwatt range can do permanent damage and this thing is 30kW. It would only require 0.001% of the energy to be reflected - you can get that much off a black surface, let alone something shiny.

Use butane instead of water, which boils at a temperature that is compatible with CPUs. The pressures involved are quite reasonable too eg (30psi).

The butane vapor then flows though a turbine to create power, through a heater exchanger to chill back down and recondense, and then is pumped back to the CPU.

Plenty of scientists have tried to use simpler explanations but there is evidence that rules them out. The best example is the bullet cluster - two galaxies collided and the various components of the cluster - stars, gas and dark matter - all behaved differntly during the collision. The gravitational lensing effects cannot be explained by theories that dont include dark matter.

The issue doesnt seem to be the code.

People are claiming that the hardware is just a re-flashed existing micro router, eg here - http://www.aliexpress.com/item...

Anonabox claim they custom designed the hardware, other are claiming it doesnt seem so, mostly it seems like it a moot point if it's cheap and offers the functionality specified.
